This is just for the convenience of description and does not represent the actual position and direction. Provided is a technical solution of a hoisting device for paralyzed patients: a hoisting device for paralyzed patients, comprising a crane mechanism capable of moving back and forth, left and right, a vertical guide mechanism, an arm support mechanism and a waist suspension mechanism.

The crane mechanism includes two guide rails 1 arranged at the front, rear, left and right, and an inverted "L"-shaped mounting frame 11 installed on the left and right ends of the guide rail 1, and the mounting frame 11 is installed on the roof of the room. The traveling mechanism is equipped with a hoist 12, and the traveling mechanism and the hoist 12 are connected with a remote control 19 for controlling the traveling. The traveling mechanism controlled by the remote controller 19 is an existing technology, which is relatively mature, similar to the overhead crane in the factory, but here, the lifting weight is low, unlike the several tons in the factory. The traveling mechanism includes a front and rear bottom plate 13 installed on the two guide rails 1, and the lower end of the bottom plate 13 is symmetrically installed with four wheels matched with the guide rail 1, and the two wheels on the left side are respectively connected to the bottom plate 13. The motor 14 and the bottom plate 13 are sleeved with a sleeve plate 15 that can slide back and forth, and the hoist 12 is installed on the left side of the upper end of the sleeve plate 15. The tube 2 protrudes from the sleeve plate 15 to the left to facilitate the insertion of the wire rope. The guide tube 2 is fixed with a support ring 211 with a circular cross-section that guides the wire rope. The right end of the sleeve plate 15 is fixed with a pull block 16, and the pull block 16 is threadedly connected There is a lead screw 17 that protrudes back and forth (note: the threads on the lead screw 17 are relatively dense in the figure, so the thread is omitted in the figure and simplified), and the two ends of the lead screw 17 are rotatably connected to the base plate 13. The support block, and one end of the lead screw 17 is connected to the second motor 171 after passing through the support block, the processor 18 and the wireless transceiver 181 are installed on the sleeve plate 15, and the processor 18 is electrically connected to the first motor 14, The second motor 171 , the hoisting machine 12 and the wireless transceiver 181 , and the wireless transceiver 181 is wirelessly connected to the remote control 19 . The remote control 19 controls the first motor 14, the second motor 171, the hoist 12 and the wireless transceiver 181 as existing technologies, which are the same as the crane technology in the factory. Therefore, the specific content will not be described in detail. At the same time, it can also be used here. Including the limit mechanism, in the front-rear direction and the left-right direction, it is the prior art.

The guide mechanism includes a vertically arranged guide pipe 2, the section of the guide pipe 2 is square, and the guide pipe 2 is installed on the left side of the lower end of the walking mechanism, and a telescopic pipe that can be moved up and down is inserted into the guide pipe 2. 21, and after the end of the wire rope of the hoist 12 is inserted through the upper end of the guide tube 2, it is fixed on the upper end of the telescopic tube 21 to pull the telescopic tube 21 to move up and down. The guiding mechanism is mainly to prevent the wire rope from shaking when hoisting the patient, and the direct use of hoisting is likely to cause the patient to shake.

The arm support mechanism includes a connecting plate 22 installed at the lower end of the telescopic tube 21 with a forward opening of a "C" shape, and the lower end of the connecting plate 22 is fixed with a horizontal plate 23 arranged on the left and right, and two horizontal forwards are installed on the horizontal plate 23. The supporting plate 24 is used to hold up the arm or hand, and the middle part of the supporting plate 24 is located just below the telescopic tube 21 so that the wire rope is close to the center of gravity of the patient. It is convenient to drag the patient's arm up, it can be supported to the armpit position, or it can be wider on both sides, which is mainly for the patient's comfort. The front end of the support plate 24 is bent upward to form a slip-off preventing portion 241 that prevents the patient from slipping off. Prevent the patient from slipping forward and play a protective role. The "C"-shaped connecting plate 22 is used here, mainly to facilitate moving the center of the patient to the lower side of the telescopic tube 21, which is consistent with the tension direction of the wire rope, reduces the force of the telescopic tube 21 in the horizontal direction, and has better stability .

The waist suspension mechanism includes a drawstring 3 fixed on the lower end of the telescopic tube 21 , and the lower end of the drawstring 3 is provided with a waist belt 31 that can be tied on the waist of the patient. The drawstring 3 and the waist belt 31 are detachably connected and can be fastened so that the height can be adjusted. Normally, the waist belt 31 is close to the upper end of the support plate 24 when it is horizontal, so that the arms can rest on the support plate 24 at the same time. When the patient is lying on the bed, it can be directly inserted under the waist for fixation to reduce the force exerted by the arm on the support plate 24, and both act on the patient at the same time. Rope 3 is shaking, more secure. The waistband 31 is provided with an opening, and the opening is connected by a Velcro 32 to adjust the tightness. Compared with direct fastening or snap-on, this kind of Velcro is more convenient, and the tightness can be adjusted better. Of course, it cannot be too thin to ensure the connection strength. It can reach a width of more than 10cm, and the patient is more comfortable.

It also includes a sliding mechanism provided on the supporting plate 24 and the horizontal plate 23 to change the distance between the two supporting plates 24 . In this way, it is convenient to adjust the distance between the two support plates 24 to deal with patients of different fat and thinness, and at the same time, it is also convenient to support or hold the patient's arms by hand, which is more comfortable and more flexible. The sliding mechanism includes a matching sliding cylinder 25 that is sleeved on the horizontal plate 23 and can move left and right, and between the sliding cylinder 25 and the supporting plate 24 is also provided with a locking mechanism that can fix anti-skid when the supporting plate 24 is pressed down. . The locking mechanism is to avoid sliding after adjustment. Here, the sliding cylinder 25 slides, and it can also be a sliding block, and then a corresponding guide groove or track is provided on the horizontal plate 23 . The locking mechanism includes a square installation groove opened in the middle of the upper end of the sliding cylinder 25, the installation groove is fixed with a guide cylinder 26 with a square upward cross-section, and a guide block 27 that is adapted to protrude upwards is inserted into the guide cylinder 26, The guide block 27 is fixed on the lower end of the support plate 24, and the support plate 24 and the sliding cylinder 25 are connected by two front and rear support springs 28, the lower end of the guide block 27 is fixed with a non-slip cylindrical stop column 29, The horizontal plate 23 is equally spaced along the length direction with circular slots 291 corresponding to the stop columns 29 penetrating up and down. When the support plate 24 supports the arm, the stop columns 29 can be inserted into the slots 291 to prevent sliding. There is a pressing distance between the stop column 29 and the clamping groove 291, and there is also a distance between the support plate 24 and the upper end of the guide cylinder 26. After the patient is pressed on the support plate 24, the spring 28 is compressed, and then the stop column 29 is pressed against the upper end of the guide cylinder 26. On the horizontal plate 23, when the patient moves left and right, the stop column 29 slides into the adjacent slot 291, or the arm can be directly placed on the support plate 24. When moving, the support plate 24 slides left and right, and the stop column 29 also slides. into the adjacent card slot, therefore, the depth of the card slot 291 is not large, only a few millimeters, so there will be no obvious subversion. In this way, sliding of the pallet 24 and the sliding cylinder 25 is avoided during the movement. It should be noted that when the stop column 29 is stuck into the card slot 291, the guide block 27 abuts on the horizontal plate 23 for support, and the support plate 24 also abuts on the upper end of the guide cylinder 26 for support, so that the stability is improved. it is good. Locking can also be done with knobs for tightening and clamping, but this is cumbersome and not convenient enough.

It also includes a disengagement prevention mechanism disposed between the support plate 24 and the horizontal plate 23 to prevent the support plate 24 from slipping off. In a normal state, the sliding cylinder 25 is prevented from sliding freely. The anti-dropping mechanism includes a cylindrical anti-skid column 4 inserted into the card slot 291 from the lower end, the anti-skid column 4 is located on one side of the sliding cylinder 25, and the anti-dropping support plate 41 is fixed at the lower end of the anti-skid column 4, and the anti-dropping support The rear end of the plate 41 is fixed with an upward anti-disconnection lever 42 , and the anti-disconnection lever 42 is fixed on the support plate 24 . When the support plate 24 is pressed down, it drives the anti-disconnection lever 42 to move downward, thereby driving the anti-skid column 4 to slide out of the card slot 291 to adjust left and right. The spring 28 with the stiffness coefficient can be realized. Of course, this should ensure that when the anti-skid column 4 slips, the stop column 29 has not been inserted into the slot 291, so the distance between the stop column 29 and the horizontal plate 23 can be slightly larger. For example, it can be 20mm to 30mm, and the height of the anti-skid column 4 can be 3mm. It should be noted that this is for reference only and can be changed by yourself in practice. This is more convenient. If the patient wants to adjust to the position, he can press down directly, and it will not slide after releasing.

The front end of the support plate 24 is stressed, and the rear end of the support plate 24 is pulled by the anti-separation lever 42 and the anti-separation support plate 41. The end force, like a lever, increases the stability of the pallet 24 .

Here, the guide tube 2, the telescopic tube 21, the connecting plate 22, the horizontal plate 23, the support plate 24, the slide cylinder 25, the guide cylinder 26, the guide block 27, the anti-dropping support plate 41 and the anti-dropping connecting plate 42 can all be made of aluminum alloy. , light weight and high strength.

Working principle: The first motor 14, the second motor 171 and the hoist 12 can be controlled by the remote controller 19, so as to realize the front, back, left and right movement of the support plate 24 and the belt 31, thereby driving the patient to move forward, backward, left and right. Covering most areas of the entire room, it can also be used by multiple people in the hospital or at home. Moreover, it is not limited to the wheelchair at the bedside, and the wheelchair can also be used farther away, which is more flexible. Compared with the mobile hoisting device on the ground, it is installed on the roof of the room, which is more stable, and there will not be a phenomenon of tipping when the whole moves as on the ground. Moreover, the ground occupies less space, and the upper space is reasonably used. When lifting, move the support plate 24 to the front side of the patient through the remote control 19, then the patient lifts his arm, the support plate 24 is slowly inserted into the patient's armpit, and the patient ties the belt 31 under the body at the same time, and can pass the Velcro 32. To adjust the tightness, the remote control 19 controls the hoist 12 to work, and pulls the telescopic tube 21 to lift the patient. Here, the waist belt 31 can play a relatively large supporting force, and the patient supports the support plate 24, so that the stability is better, and there is a lifting effect. The belt 31 also has a hand-held support plate 24, which avoids shaking and rotation, which is safer. In addition, the height can be changed after adjusting the elasticity through the Velcro 32, so that the hand-held height position of the support plate 24 can be adjusted, which is more flexible and at the same time , the armpit position can also be directly placed on the support plate 24, which plays a main supporting role, and the waist belt 31 plays an auxiliary role. This requires the two support plates 24 to be closer and the waist belt 31 to be looser. When the support plate 24 is pressed down, the spring 28 is compressed, the stop column 29 is pressed against the horizontal plate 23, and the stop column 29 slides into the adjacent card slot 291 under the left and right shaking, so as to realize anti-skid, so that there is no need to lock, and the automatic locking Dead slip. When the arm is not on the support plate 24, under the action of the spring 28, the support plate 24 drives the anti-detachment support plate 41 and the anti-detachment connecting lever 42, so that the anti-skid column 4 is pressed against the lower end of the horizontal plate 23. Once it slides, the anti-skid column 4 will It slides into the adjacent card slot 291 to avoid sliding, which is more secure and does not need to be locked manually. The front end of the support plate 24 is stressed, and the rear end of the support plate 24 is pulled by the anti-separation lever 42 and the anti-separation support plate 41. The end force, like a lever, increases the stability of the pallet 24 .

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, and substitutions can be made in these embodiments without departing from the principle and spirit of the invention and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
