Background technique

As a means of transportation, the suspended sky rail train mainly functions to transport passengers. Sky Train (SkyTrain), also known as sky railway, or empty rail for short, is a branch of rail transit. The basic principle is similar to that of the subway and light rail, but its carriages are suspended carriages. The aerial tram is a train that runs under the aerial track in a suspended manner. The suspended air rail train is mainly divided into three parts: car body, bogie and track beam frame. The car body includes the cockpit and the passenger compartment. The track beam body is the running track of the empty rail train.

Example 1:

As shown in Figures 1 and 2, this embodiment provides a suspended train carriage 200, including a chassis 210 and a suspended train escape device. The suspended train escape device is arranged at the bottom of the carriage and connected to the chassis.

As shown in FIG. 2 and FIG. 3 , the suspended train escape device mainly includes two rails 110 , an escape slide 130 and two guide wheels 140 . The escape slide 130 can slide along the track 110 , and when sliding, the guide wheels 140 guide the escape slide 130 .

The two rails 110 are respectively arranged on two sides of the chassis 210 , are fixedly connected with the chassis 210 , and extend along the length direction of the chassis 210 . A gap is provided between the track 110 and the chassis 210 to form an accommodating space 120 for accommodating the escape slide 130 . The track 110 and the chassis 210 are inclined at an angle, so that one end of the accommodating space 120 is larger and the other end is smaller, that is, the accommodating space 120 includes a large end 122 and a small end 124 .

The escape slide 130 has a plate-like structure as a whole, and grooves are arranged on its surface, and the grooves extend along the length direction of the escape slide 130 . The end of the escape slide 130 close to the small end 124 is provided with a roller 132 , and the axis of the roller 132 is parallel to the width direction of the escape slide 130 . Due to the arrangement of the rollers 132, the frictional force experienced by the escape slide 130 is relatively small when sliding.

In order to prevent the escape slide 130 from sliding along the track 110 during normal driving, a baffle 1222 is provided at the large end 122 of the accommodating space 120 .

Further, a rack 134 is also provided on the escape slide 130 , and the rack 134 extends along the length direction of the escape slide 130 . A gear 142 is provided on the guide wheel 140 for meshing with the rack 134 . The suspended train escape device is also provided with a driving device (not shown in the figure), which is connected with the guide wheel 140 and used to drive the guide wheel 140 to rotate. In this embodiment, the drive device adopts a variable frequency motor, and the variable frequency motor is connected to the storage battery in the compartment.

In addition, the suspended train escape device further includes a guide rail 150 disposed on the upper part of the accommodating space 120 , and the rail surface of the guide rail 150 is spaced apart from the rail 110 . The escape slide 130 is disposed between the guide rail 150 and the track 110 . The rail surface of the guide rail 150 is provided with a plurality of protrusions and recesses, so that the rail surface of the guide rail 150 is a curved surface, that is, the height of the guide rail 150 varies along the sliding direction of the escape slide 130 . A hook 152 is also provided at the end of the guide rail 150 close to the large end 122 of the accommodating space 120 .

The working principle of the suspended train escape device provided in this embodiment is as follows: an escape door is provided at the rear of the carriage, and when the carriage stops in mid-air, the passenger opens the escape door and opens the baffle plate 1222 of the large end 122 of the accommodating space 120 Then start the driving device, the driving device drives the gear 142 to rotate, and the gear 142 drives the rack 134 to rotate through meshing, and then drives the escape slide 130 to slide. With the sliding of the escape plate, the end of the escape plate near the small end 124 of the accommodating space 120 is warped so that the guide wheel 140 cooperates with the rail surface of the guide rail 150, and the guide wheel 140 slides along the rail surface of the guide rail 150. Finally, the end of the escape slide 130 touches the ground, and passengers can slide down to the ground through the escape slide 130 .

In order to facilitate retracting the lowered escape slide 130 into the accommodating space 120, a retracting device is also provided, and the retracting device includes a pull rope, a rope receiving wheel and a handle. One end of the pull rope is connected to the escape slide 130 , and the other end is wound on the rope take-up wheel. By turning the handle, the rope take-up wheel tightens the rope to retract the escape slide 130 into the accommodating space 120 .

Since the guide rail 150 is provided, and the height of the guide rail 150 presents high and low changes along the sliding direction of the escape slide 130, when the escape slide 130 slides downward, the roller 132 at the end of the escape slide 130 moves along the high and low rail surface of the guide rail 150. Sliding can prevent the escape slide 130 from sliding too fast, causing the hook 152 of the big end 122 to be damaged and causing the escape slide 130 to fall off from the accommodating space 120 . Especially when no driving device is provided and only slides down by gravity, the role of the guide rail 150 is even more important.

It should be noted that this embodiment is a preferred embodiment, and in other embodiments, the guide rail 150 may not be provided, and the hook 152 may be provided at the large end 122, and may be connected with the track 110 or the chassis 210; or, in other embodiments In the example, it is not possible to set the retracting device, and it can be retracted by means of transportation; or, in other embodiments, the driving device and the gear 142 may not be provided. Under the effect of gravity, the escape slide 130 can also slide down from the accommodating space 120 so that one end thereof touches the ground.

Example 2:

As shown in Fig. 4, this embodiment provides a suspended train escape device, the basic structure of which is the same as that of the embodiment. The difference is that a lubricating device 160 is added for lubricating the gear 142 and rack 134 . Because the suspended train escape device is only used when the train breaks down, under normal circumstances, the gear 142 does not rotate. Therefore, the tooth surfaces of the gear 142 and the rack 134 are prone to rust, resulting in excessive friction of the rotation of the gear 142 , so adding a lubricating device 160 can improve its meshing performance.

As shown in FIG. 5 , the lubricating device 160 includes a cylinder 161 , a piston 162 and a piston rod 163 . The cylinder 161 is arranged parallel to the chassis 210 and is fixedly connected to the carriage. The cylinder 161 is similar to the piston 162 , and the piston 162 separates the inner cavity of the cylinder 161 to form a first space 1611 and a second space 1612 . A compression spring is provided in the first space 1611, and the compression spring makes the piston 162 have a tendency to compress the second space 1612, and the second space 1612 communicates with the outside world.

The lubricating device 160 also includes an oil tank 164 , a first oil delivery pipe 165 and a second oil delivery pipe 166 . One end of the first oil delivery pipe communicates with the first space 1611 of the cylinder body 161 , and the other end communicates with the bottom of the oil tank 164 . The first oil delivery pipe is also provided with a first one-way valve 1652 , and the first one-way valve 1652 allows the lubricant to only flow from the oil tank 164 into the first space 1611 .

One end of the second oil delivery pipe is connected to the first space 1611 , and the other end leads to the meshing position of the gear 142 and the rack 134 . A second one-way valve 1662 is provided on the second oil delivery pipe, and the second one-way valve 1662 allows the lubricant to flow out only from the first space 1611 .

As shown in FIG. 5 and FIG. 6 , the free end of the piston rod 163 is provided with a toggle rod 1632 . The guide wheel 140 also includes a rotating wheel 144 whose outer diameter is larger than the addendum circle diameter of the gear 142, and whose end is connected with the end of the gear 142, and the rotating wheel 144 is close to the outside of the compartment. A plurality of rotating plates 1442 are arranged on the circumferential surface of the rotating wheel 144 along the circumferential direction. When the rotating plates 1442 rotate with the rotating wheel 144, the rotating plates 1442 can collide with the toggle rod 1632 on the piston rod 163, thereby causing the piston 162 to compress The direction of the first space 1611 moves, and with the rotation, the rotating plate 1442 is separated from the toggle lever 1632 .

The working principle of the lubricating device 160 is as follows:

After the driving device starts, the driving device drives the gear 142 and the rotating wheel 144 to rotate, and the rotating plate 1442 on the rotating wheel 144 rotates, because the toggle rod 1632 of the piston rod 163 is arranged on the top of the rotating wheel 144, and the distance is relatively small. close, so that the rotating plate 1442 can just collide with the toggle rod 1632 on the piston rod 163, thereby pushing the piston 162 to compress the first space 1611, and the piston 162 compresses the lubricant in the first space 1611 to the gear 142 through the second oil delivery pipe 166 Lubricate. After the toggle rod 1632 is separated from the rotating plate 1442, the piston 162 is reset under the action of the compression spring in the first space 1611, and the first space 1611 generates negative pressure, and oil is sucked from the oil tank 164 through the first oil delivery pipe 165. As the rotating wheel 144 rotates, the next rotating plate 1442 touches the toggle rod 1632 of the piston rod 163 , thereby compressing the first space 1611 and compressing the lubricant to the meshing position of the gear 142 and the rack 134 .

In order to recover the lubricant, an oil receiving container (not shown) is arranged under the gear 142 . Since the two gears 142 are respectively located on both sides of the carriage, a set of lubricating devices 160 needs to be respectively arranged on both sides of the carriage. The number of rotating plates 1442 on the rotating wheel 144 can be adjusted to other suitable numbers according to actual conditions.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
