Description

Power system drainage pump lifting aid

technical field

The invention relates to a lifting auxiliary device for a drainage pump in a power system.

Background technique

The focus of the substation's flood control work is to ensure the safety of the substation during the flood season, and to meet the requirement that the substation and its production and living facilities will not be flooded when encountering heavy rain or flood exceeding the design standard. Special attention should be paid to substations with low terrain and substations with flooding experience. In the process of flood control, ensuring the normal and effective drainage work is one of the key points of substation flood control work.

Since there is no special auxiliary equipment for lifting the drainage pump in the power system, at present, the method of manually lifting the drainage pump is used to enter and exit the drainage well, that is, the top of the drainage pump is tied with a rope, and the flood control personnel grasp the rope and rely on Manually lower the drainage pump into the fire well (drainage well), and the lifting process is the opposite. Since a drainage pump weighs more than 25 kilograms, in order to ensure the safety of personnel and the pump, two people are often required to cooperate. While this method is simple and practical, it has brought many problems, such as seriously consuming the physical strength of the flood control personnel, taking up too many human resources and causing tension in the flood control personnel, improper force causing the drainage pump to swing and hit the well wall to damage the drainage pump, and because all It is a manual operation, so it is easy to squeeze fingers by the water pump or scratch the skin by the rope when lowering or lifting the water pump. In addition, when transferring the drainage pump, at least two people are required to carry it, which is time-consuming and laborious, and reduces the drainage efficiency. This defect is more obvious during emergency flood control.

Contents of the invention

The technical problem to be solved by the present invention is to provide a power system drainage pump lifting assistant with reasonable structure, stable lifting, safe operation, time-saving and labor-saving, one-person operation and fast transfer.

In order to solve the above technical problems, the structural features of the power system drainage pump lifting aid are as follows: it includes a roller installed on the base, a rotating shaft is installed above the base through a bracket, a roller is coaxially fixed on the rotating shaft, and a connecting wheel is wound on the roller. The traction rope of the drainage pump has a through hole on the base, a baffle is placed on the base, a pump box containing the drainage pump is arranged in the middle of the baffle, the pump box is clamped in the through hole, and a crank is fixed at the end of the shaft. A positioning plate is coaxially fixed on the rotating shaft, and a locking piece is arranged between the positioning plate and the bracket.

The power system drainage pump lift assist device realizes stable lift by moving the bracket type rocker arm assist structure, simple operation, time-saving and labor-saving, can be operated by one person, and the transfer is fast.

The mobile bracket type rocker arm assisting structure mainly includes a bracket installed on the base and a crank on the installation bracket. The base is the underlying structure of the drainage pump lifting aid of the power system, which can provide stable support for the bracket, and can also carry or place the drainage pump. The crank is installed on the upper part of the support through the rotation of the rotating shaft, and the outer periphery of the rotating shaft is fixed with a cylinder that can rotate coaxially with the rotating shaft. Like this, when the crank is driven to rotate, the crank will drive the cylinder to rotate synchronously through the rotating shaft. A traction rope is wound around the drum, one end of the traction rope is fixed on the drum, and the other end of the traction rope is fixedly connected with the drainage pump. Therefore, when the driving crank is turned, the drum will wind or release the traction rope, so that the sump pump can be lifted or lowered by the traction rope, and the operation is very simple. The power system drainage pump lifting assistant realizes the automatic lifting of the drainage pump through the mechanical transmission of the crank handle and the drum, which avoids the direct contact of the workers with the traction rope or the drainage pump with their hands, and fundamentally solves the problem of pinching fingers and scratching the skin. safe question. Because the arm length of the crank is set to be longer than the radius of the drum, a relatively small force can be applied to the crank to lift the heavy drainage pump through the drum, which saves effort and can be operated by one person. A locking piece is arranged between the roller and the support, through which the rolling can be fixed and locked on the support, so that the rolling can not continue to rotate under the action of gravity of the drainage pump, thus playing a locking role.

The base is provided with a through hole corresponding to the drum, through the through hole, the drainage pump can be lowered into the drainage well, which is very convenient. The through hole also has another function, which is to limit the pulling rope of the drainage pump, that is to say, the drainage pump can only be lowered or raised within the range corresponding to the through hole, which improves the stability of the drainage pump when it is raised and lowered. It can effectively avoid the collision between the drainage pump and the well wall, and ensure the integrity and service life of the drainage pump. A baffle is also placed on the base, and the baffle can completely cover the through hole, so that when the water is not drained, it can carry the drainage pump and prevent the drainage pump from falling from the through hole. A pump box is arranged in the middle of the baffle, and the main function of the pump box is to hold the drainage pump. Because the drainage pumps are roughly cylindrical, after the drainage pumps are placed in the pump box, the drainage pumps can be avoided from rolling during the transfer, which ensures the smooth progress of the transfer. The bottom of the pump box is snap-fitted with the through hole, which not only plays a role in blocking the through hole, but also plays a role in positioning the baffle through the through hole.

There are rollers on the base, through which the lifting auxiliary device of the entire power system drainage pump can be easily pushed and transferred. The operation saves time and effort, and can be operated by one person. It is especially suitable for emergency drainage.

As an improvement, one end of the baffle is hinged with the base through a hinge shaft, and a wire roller is installed on the bracket to rotate. The end of the wire roller is fixed with a rocker arm that can drive the wire roller to rotate, and a wire roller disc is fixed coaxially on the wire roller. A locking piece is arranged between the roller disc and the bracket, and a stay rope connected with the other end of the baffle is wound on the wire roller.

After one end of the baffle is hinged on the base through a hinge shaft, the baffle can be moved by turning to realize the opening or covering of the through hole. For the convenience of description, the end of the baffle near the hinge shaft is called the hinged end, and the other end is called the movable end. In this way, when the through hole needs to be opened, only the movable end of the baffle is pulled up, and the baffle can be lifted under the support of the hinged end, which is more labor-saving than the direct lifting method to open the through hole, and is especially suitable for It is helpful to improve the efficiency of emergency rescue when operated by one person.

A wire roller driven by a rocker arm is rotated on the bracket, and a pull rope is wound on the wire roller, and the end of the pull rope is fixedly connected with the movable end of the baffle, so that the wire roller can be driven to wind by rotating the rocker arm at the end of the wire roller Pull the wire, thus play the role of pulling up the movable end of the baffle, and also play the role of lifting the baffle or opening the through hole, and the operation is very simple. The power system drainage pump lifting assistant realizes the automatic opening or bedding of the baffle through the mechanical transmission of the rocker arm and the line roller, which avoids the workers from directly touching the baffle with their hands, and fundamentally solves the problem of being crushed when operating the baffle. Safety issues such as fingers and scratches on the skin. Because the length of the rocker arm is much longer than the length of the radius of the wire roller, driving the pull rope and the movement of the baffle through the rocker arm and the wire roller can save labor, and is especially suitable for one-person operation. The wire roller is coaxially fixed with a wire roller disk, and there is a locking piece between the wire roller disk and the bracket. The function of locking the baffle is very simple to operate.

When in use, first turn the crank to lift the drainage pump away from the baffle through the traction rope, and operate the locking piece between the positioning plate and the bracket to lock the positioning plate and the drainage pump, then turn the rocker to pull the baffle through the wire roller Lift up, and operate the locking piece between the line roller plate and the bracket to lock the line roll plate and the baffle, and finally unlock the locking piece between the positioning plate and the support, and reversely turn the crank to slowly release the drain pump from the through hole. Slowly put it into the fire well, and finally lock the drainage pump and turn on the electricity to drain water. The operation is very simple and can be operated by one person. When it is necessary to lift the drainage pump after draining, just perform the above steps in reverse order, which is very simple.

As an improvement, two supporting rods that can only swing at the bottom of the base are respectively hinged at both ends of the bottom of the base. Aligned stringing holes are arranged on the top, and stringing rods for fixing and stringing each support rod under the base are inserted in the stringing holes.

The support bar is hinged at the end of the base, which can extend the size of the base and enhance the stability of the support of the base. Because the hinged end of the support rod is provided with a limit block matched with the end of the base, the support rod can only swing within the range below the base. For the convenience of description, the state when the support rods are swung towards each other and close to the bottom of the base is called the retracted state, and the state when the support rods are swung backwards and swung to make the limit block touch the end of the base is called the stretched state . In the stretched state, the four support rods prop up the rollers off the ground under the support of the limit block and the end of the base. At this time, the entire power system drainage pump lifting aid is completely supported by the four support rods. In this state, because the support rod is supported outward, its support range is much larger than the support coverage of the base or the rollers, effectively ensuring the stability of the power system drainage pump lifting assistant when draining water. There are stringing holes on the support rods. In the contracted state, the stringing holes on the four supporting rods are set coaxially. At this time, the four supporting rods can be connected in series through the stringing rods, which also plays a role in locking. The role of the support rod.

As an implementation manner, the locking member includes positioning teeth fixed on the outer periphery of the positioning plate, and a positioning plate cooperating with the positioning teeth is hinged on the bracket.

When the positioning plate is clamped between the positioning teeth, the positioning plate will not be able to rotate because of the blocking of the positioning plate, thus playing the role of locking the drum, and the operation is very simple. The locking parts between the wire roller disc and the bracket are the same in structure as the locking parts between the positioning disc and the bracket, that is, the outer circumference of the wire roller disc is also uniformly distributed with positioning teeth, and the bracket is hinged with a hinge that matches the positioning teeth. Positioning plate. The operation method is also the same, and when the locking operation and the unlocking operation are performed, only the positioning plate needs to be rotated, and the operation is very simple.

As an improvement, a pull ring is fixed on the baffle.

The baffle can be manually lifted or lowered through the pull ring, which has the function of opening the through hole in an emergency, and the operation is very simple.

To sum up, the power system drainage pump lifting auxiliary device with this structure has reasonable structure, stable lifting, simple operation, time-saving and labor-saving, can be operated by one person, and the transfer is fast, which helps to improve work efficiency. It is especially suitable for It is used for emergency drainage.

detailed description

As shown in the figure, the power system drainage pump lifting aid includes a base 1 on which a bracket 3 is fixedly installed, and a rotating shaft 4 is installed on the upper part of the bracket 3 for rotation. A drum 5 is coaxially fixed on the outer periphery of the rotating shaft 4 , and a traction rope 7 connected to the drainage pump 6 is wound on the drum 5 , and a crank handle 8 is fixed at the end of the rotating shaft 4 . The base 1 is the underlying structure of the drainage pump lifting aid of the power system, which can provide stable support for the bracket 3 and can also carry or place the drainage pump 6 . Because the crank 8 is installed on the upper part of the bracket 3 through the rotation of the rotating shaft 4, and the outer periphery of the rotating shaft 4 is fixed with a drum 5 that can rotate coaxially with the rotating shaft, so when the crank 8 is driven to rotate, the crank 8 will be driven by the rotating shaft 4. The drums 5 rotate synchronously. A traction rope 7 is wound around the drum 5 , one end of the traction rope 7 is fixed on the drum 5 , and the other end of the traction rope 7 is fixedly connected with the drainage pump 6 . Therefore, when the crank is driven to rotate, the drum 5 will wind or release the traction rope 7, so that the drainage pump 6 can be lifted or lowered by the traction rope, and the operation is very simple. Because the arm length of rocking handle 8 is set longer than the radius of cylinder 5, so apply less power to rocking handle and just can lift heavier drainage pump by cylinder, played the effect of saving labor, one person just can operate. A locking piece is arranged between the drum 5 and the support 3, through which the rolling can be fixedly locked on the support, so that the rolling can not continue to rotate under the action of gravity of the drainage pump, thus playing a locking role.

The base 1 is provided with a through hole 10 corresponding to the drum 5, through which the drainage pump 6 can be lowered into the drainage well, which is very convenient. The through hole 10 also has another function, which is to limit the pulling rope 7 for pulling the drainage pump. The stability of the pump effectively avoids the collision between the drainage pump and the well wall, ensuring the integrity and service life of the drainage pump. A baffle 11 is also placed on the base 1, and the baffle 11 can completely cover the through hole, so that it can carry the drainage pump and prevent the drainage pump 6 from falling from the through hole 10 when not draining. The middle part of the baffle plate 11 is provided with a pump box 12 , and the main function of the pump box 12 is to hold the drainage pump 6 . Because the drainage pumps 6 are generally cylindrical, after the drainage pumps 6 are placed in the pump box 12, the drainage pumps 6 can be prevented from rolling during transfer, which ensures the smooth progress of the transfer. The bottom of the pump box 12 is clip-fitted with the through hole 10, which not only plays a role in blocking the through hole, but also plays a role in positioning the baffle plate 11 through the through hole. The baffle plate 11 is fixedly provided with a pull ring 19, through which the baffle plate 11 can be lifted up or put down quickly manually, thereby opening the through hole 10 in an emergency, and the operation is very simple.

The arm 23 drives the wire roller to wind the backguy, thereby playing the role of pulling up the movable end of the baffle plate, and also playing the role of raising the baffle plate 11 or opening the through hole, and the operation is very simple. Because the length of the rocker arm is much longer than the radius of the wire roller, it can save labor by driving the pull rope and the movement of the baffle through the rocker arm and the wire roller. It can be operated by one person, especially suitable for emergency drainage. Wire roller 21 is coaxially fixed with wire roller disk 22, and between wire roller disk 22 and support 3 is provided with locking member, by operating this locking member, wire roller disk can be locked on the support, has also just played. The function of locking wire roller and locking baffle, the operation is very simple.

When in use, first turn the crank 8 to lift the drain pump 6 away from the baffle plate 11 through the traction rope, and operate the locking member between the positioning plate and the bracket to lock the positioning plate 9 and the drainage pump, then turn the rocker arm 23 to pass the line Roller 21 pulls up the baffle, and operates the locking member between the wire roller disc 22 and the bracket 3 to lock the wire roller disc and the baffle, and finally unlocks the locking member between the positioning disc and the bracket, and reversely rotates the rocker Slowly put the drainage pump 6 into the fire well through the through hole, and finally lock the drainage pump and turn on the power to drain water. The operation is very simple and can be operated by one person. When it is necessary to lift the drainage pump after draining, just perform the above steps in reverse order, which is very simple.

In this embodiment, the locking member between the positioning disc and the support has the same structure as the locking member between the wire roller disc and the support. Take the locking member between the positioning plate and the bracket as an example, the locking member includes positioning teeth 17 fixed on the outer periphery of the positioning plate, and the positioning plate 18 cooperating with the positioning teeth 17 is hinged on the support. When the positioning plate is clamped between the positioning teeth, the positioning plate will not be able to rotate because of the blocking of the positioning plate, thus playing the role of locking the drum, and the operation is very simple.

Two ends of the bottom of the base 1 are respectively hinged with two support rods 13 that can only swing at the bottom of the base 1, and the hinged ends of the support rods 13 are fixedly provided with a limit block 14 that cooperates with the end of the base to support the rollers off the ground. The supporting rods are provided with aligned stringing holes 15, and the stringing holes 15 are inserted with stringing rods 16 for fixing the supporting rods in series under the base. The supporting rod 13 is hinged at the end of the base, which can play the role of extending the size of the base and enhancing the stability of the support of the base. Because the hinged end of the support rod 13 is provided with a limit block matched with the end of the base, the support rod 13 can only swing within the range below the base. For the convenience of description, the state when the support rods 13 swing toward each other and close to the bottom surface of the base is called the retracted state, and the state when the support rods 13 swing back and swing to make the limit block 14 touch the end of the base is called the contracted state. Open state. In the stretched state, the four support rods prop up the rollers off the ground under the support of the limit block 14 and the end of the base. At this time, the entire power system drainage pump lifting aid is fully supported by the four support rods 13 . In this state, because the support rod 13 is supported outward, its support range is much larger than the support coverage of the base or the rollers, which effectively ensures the stability of the power system drainage pump lifting assistant when draining water. The supporting rods are provided with string mounting holes 15. When in contraction state, the string mounting holes 15 on the four supporting rods are coaxially arranged.
