[0001] This utility model relates to the field of escape and evacuation technology, specifically to an emergency escape and evacuation ramp device for rail transit vehicles. Background Technology

[0002] Existing rail transit systems, whether above or below ground, require emergency evacuation ramps at escape points. However, existing escape ramps have a problem: without human intervention, some unruly individuals may use them, or even occupy them entirely. Therefore, an emergency evacuation ramp design is needed that allows it to be opened and used whenever needed for emergency evacuation, and then rolled up when not in use to prevent unauthorized occupation and disruption of escape routes by disorderly crowds. Thus, an emergency evacuation ramp device for rail transit vehicles is required to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides an emergency escape and evacuation ramp device for rail transit vehicles, which solves the problems mentioned in the background.

[0004] This utility model provides the following technical solution: an emergency escape and evacuation ramp device for rail transit vehicles, comprising: an escape platform, a support column connected to the bottom of the escape platform, railings installed on the outer wall of the escape platform, a multi-directional connector provided on the outer wall of the escape platform, a connecting pin connected to the inner wall of the multi-directional connector, a side guide frame sleeved on the outer wall of the connecting pin, an inner groove formed on the outer wall of the side guide frame, a transition wheel connected to the outer wall of the side guide frame, a fixed shaft connected to the outer wall of the multi-directional connector, a rubber pad sleeved on the outer wall of the fixed shaft, a tension sleeve sleeved on the outer wall of the fixed shaft, a side end sleeved on the outer wall of the fixed shaft, an aluminum honeycomb connected to the outer wall of the side end, a guide rod connected to the other side of the aluminum honeycomb away from the side end, a roller sleeved on the outer wall of the guide rod, a belt sleeved on the outer wall of the guide rod, a fixed rod connected to the outer wall of the escape platform, a hand control panel movably connected to the outer wall of the fixed rod, and a meshing wheel connected to the outer wall of the hand control panel.

[0005] Preferably, one end of the connecting pin is threaded into the inner cavity of the multi-directional connector, and the end of the side guide away from the connecting pin is placed on the ground.

[0006] Preferably, the bottom of the side end is connected to an aluminum plate, and the aluminum plate has an aluminum honeycomb structure on both sides.

[0007] Preferably, the inner wall of the elastic sleeve is threaded to the outer wall of the fixed shaft, and a rubber pad is disposed between the elastic sleeve and the side end.

[0008] Preferably, the aluminum honeycomb is made of composite lightweight and high-strength materials, and the core material of the aluminum honeycomb is designed in a honeycomb shape.

[0009] Preferably, the roller is parallel to the inner groove, and the outer diameter of the roller is smaller than the inner diameter of the inner groove.

[0010] Preferably, the outer wall of the meshing wheel is engaged with a take-up and release wheel, and the hand control panel controls the rotation of the take-up and release wheel through the meshing wheel.

[0011] Preferably, the side of the belt away from the guide rod is sleeved on the outer wall of the take-up and release wheel, and the middle section of the belt passes through the outer wall of the transition wheel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The emergency escape ramp device for this rail transit vehicle is equipped with a hand control panel, a winding wheel, a belt, and a transition wheel. When the winding wheel rotates, it pulls the belt to wind up. After the belt passes the transition wheel, a guide rod is attached to the other side.

After the aluminum honeycomb is unfolded, it can be used as an emergency escape ramp.

[0014] 2. The emergency escape ramp device of this rail transit vehicle, through the setting of elastic sleeves, rubber pads, fixed shafts, side ends and other structures, allows the aluminum honeycomb on the device to shrink its overall length when not in use for emergency purposes, thanks to the honeycomb design of the aluminum honeycomb itself. In addition, when the elastic sleeves on the device are tightened, the rubber pads are tightly attached to the outer wall of the side ends, so that when the side ends on the device are fitted onto the outer wall of the fixed shaft, the aluminum honeycomb will not rotate in the direction of the transition wheel, thus preventing the aluminum honeycomb on the device from being stretched.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 An emergency escape ramp device for rail transit vehicles includes: an escape platform 1, a support column 2 connected to the bottom of the escape platform 1, a railing 3 installed on the outer wall of the escape platform 1, a multi-directional connector 4 provided on the outer wall of the escape platform 1, a connecting pin 5 connected to the inner wall of the multi-directional connector 4, a side guide 6 sleeved on the outer wall of the connecting pin 5, an inner groove 7 formed on the outer wall of the side guide 6, a transition wheel 8 connected to the outer wall of the side guide 6, a fixed shaft 9 connected to the outer wall of the multi-directional connector 4, and a sleeve on the outer wall of the fixed shaft 9. A rubber pad 10 is attached. A tension sleeve 11 is fitted onto the outer wall of the fixed shaft 9. A side end 12 is fitted onto the outer wall of the fixed shaft 9. An aluminum honeycomb 13 is connected to the outer wall of the side end 12. A guide rod 14 is connected to the other side of the aluminum honeycomb 13 away from the side end 12. A roller 15 is fitted onto the outer wall of the guide rod 14. A belt 16 is fitted onto the outer wall of the guide rod 14. A fixed rod 17 is connected to the outer wall of the escape platform 1. A hand control panel 18 is movably connected to the outer wall of the fixed rod 17. A meshing wheel 19 is connected to the outer wall of the hand control panel 18.

[0023] Wherein; one end of the connecting pin 5 is threaded into the inner cavity of the multi-directional connector 4, and the side guide 6 away from the connecting pin 5 is placed on the ground. By placing the side guide 6 away from the connecting pin 5 on the ground, the side of the side guide 6 on the device that is close to the multi-directional connector 4 is sleeved on the outer wall of the connecting pin 5. While the connecting pin 5 is connected to the multi-directional connector 4, the side guide 6 is limited between the multi-directional connector 4 and the connecting pin 5, so that the side guide 6 on the device can achieve stability at both ends.

[0024] Among them, the bottom of the side end 12 is connected to an aluminum plate, and the aluminum plate is the two sides of the aluminum honeycomb 13. By connecting the bottom of the side end 12 of the device to the aluminum plate, the two sides of the aluminum honeycomb 13 of the device are set as aluminum plate covers, and the four side ends 12 are connected to the four corners of the aluminum plate, so that one side of the aluminum honeycomb 13 is sleeved on the outer wall of the fixed shaft 9 by two side ends 12, and then the two side ends 12 on the other side are connected to two guide rods 14.

[0025] The inner wall of the elastic sleeve 11 is threadedly connected to the outer wall of the fixed shaft 9, and the rubber pad 10 is disposed between the elastic sleeve 11 and the side end 12. When the inner wall of the elastic sleeve 11 is threadedly connected to the outer wall of the fixed shaft 9, the side end 12 is movably sleeved on the outer wall of the fixed shaft 9. First, the rubber pad 10 is sleeved on the outer wall of the fixed shaft 9 and located on the outside of the side end 12. Then, when the elastic sleeve 11 is threadedly connected to the fixed shaft 9, the rubber pad 10 is pushed to fit tightly against the outer wall of the side end 12 when the elastic sleeve 11 is screwed onto the fixed shaft 9.

[0026] Among them, the aluminum honeycomb 13 is made of composite lightweight high-strength material, and the core material of the aluminum honeycomb 13 is designed in a honeycomb shape. By using composite lightweight high-strength material for the aluminum honeycomb 13 in the device, the core material of the aluminum honeycomb 13 in the device is set in a hexagonal honeycomb shape. By utilizing the design characteristics of the honeycomb shape, the aluminum honeycomb 13 in the device can shrink and expand, so that the aluminum honeycomb 13 in the device can be fully unfolded when needed.

[0027] Wherein; the position of the roller 15 is parallel to that of the inner groove 7, and the outer diameter of the roller 15 is smaller than that of the inner diameter of the inner groove 7. By making the position of the roller 15 on the device parallel to that of the inner groove 7, when the roller 15 on the device is movably sleeved on the outer wall of the guide rod 14, the roller 15 on the device contacts the inner wall of the inner groove 7 after the position is rotated, so that when the aluminum honeycomb 13 is fully expanded, the roller 15 on the device slides down along the inner wall of the inner groove 7.

[0028] The outer wall of the meshing wheel 19 is engaged with the take-up and release wheel 20, and the hand control disc 18 controls the take-up and release wheel 20 to rotate through the meshing wheel 19. The take-up and release wheel 20 is engaged with the outer wall of the meshing wheel 19, so the hand control disc 18 rotates under manual control. The meshing wheel 19 engages with the take-up and release wheel 20, driving the take-up and release wheel 20 to rotate, thereby causing the take-up and release wheel 20 to perform a winding operation, and thus causing the belt 16 on the device to gradually wind up towards the outer wall of the take-up and release wheel 20.

[0029] The belt 16 is sleeved on the outer wall of the take-up and release wheel 20 on the other side away from the guide rod 14. The middle section of the belt 16 passes through the outer wall of the transition wheel 8. As the take-up and release wheel 20 rotates, it pulls the belt 16 to wind up. After the belt 16 passes through the transition wheel 8, the other side of the belt 16 is sleeved on the guide rod 14. This causes the guide rod 14 to pull the aluminum honeycomb 13 to rotate clockwise, thereby expanding and lengthening the aluminum honeycomb 13 towards the transition wheel 8.

[0030] The working principle is as follows: First, by setting up a hand control panel 18, a take-up and release wheel 20, a belt 16, and a transition wheel 8, the take-up and release wheel 20 rotates, pulling the belt 16 to wind up. After the belt 16 passes the transition wheel 8, the other side is connected to the guide rod 14, which in turn pulls the aluminum honeycomb 13 to rotate clockwise. This causes the aluminum honeycomb 13 to expand and lengthen towards the transition wheel 8, and after the aluminum honeycomb 13 is unfolded, it can be used as an emergency evacuation ramp. Then, by setting up a tensioning sleeve 11, ... The structure of rubber pad 10, fixed shaft 9, and side end 12 allows the aluminum honeycomb 13 on the device to shrink its overall length when emergency use is not required, thanks to its honeycomb design. Furthermore, the tightening sleeve 11 on the device ensures that the rubber pad 10 fits tightly against the outer wall of the side end 12 when tightened. This prevents the aluminum honeycomb 13 from rotating in the direction of the transition wheel 8 when the side end 12 is fitted onto the outer wall of the fixed shaft 9, thus preventing the aluminum honeycomb 13 from elongating.

[0031] 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, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
