Description

Technical Field

[0001] This utility model belongs to the field of subway vehicle evacuation ramps. Specifically, this utility model relates to an emergency evacuation ramp for subway vehicles. Background Technology

[0002] As an important part of urban public transportation, the safety and passenger evacuation efficiency of subway vehicles are key considerations in the design and manufacturing process. Emergency evacuation doors, as life channels for passengers to quickly evacuate in special circumstances, are directly related to passenger safety in terms of their reliability. In the existing technology, the deployment and retraction process of evacuation ramps is relatively complex and requires multiple operators to carry out the deployment or retraction process, which is inconvenient for emergency evacuation in dangerous situations.

[0003] To address the aforementioned problems, patent document 111252097B discloses a locking device for an emergency evacuation ramp in urban rail transit, comprising an emergency evacuation ramp and a curved rod assembly. The emergency evacuation ramp includes a pedal lock, a lock frame, a pedal, a lock stop, and a ramp retraction device. The pedal lock and lock frame are located at the front end of the emergency evacuation ramp, and the lock stop is located in front of the ramp retraction device. The curved rod assembly consists of two curved rods, each with a handle. When the emergency evacuation ramp is in the retracted state, the curved rod assembly inserts into the lock frame and lock stop, locking the emergency evacuation ramp. When the emergency evacuation ramp is in the retracted state, after the curved rod assembly inserts into the lock frames on both sides of the emergency evacuation ramp and the lock stop located in front of the ramp retraction device, it will not unfold under external force, preventing accidents. The curved rod assembly has handles, but these do not solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0019] Figure 1 This is a schematic diagram of the structure of the emergency evacuation ramp for subway vehicles in an embodiment of this utility model.

[0020] like Figure 1 As shown, the emergency evacuation ramp for subway vehicles provided by this utility model includes a ramp support 10 and a telescopic ramp structure 20 connected to the ramp support 10. The ramp support 10 is installed on the frame of the subway vehicle, and the telescopic ramp structure 20 is movably connected to the ramp support 10. The telescopic ramp structure 20 can be easily deployed or retracted, and can be quickly deployed for emergency evacuation in the event of a dangerous situation, reducing the possibility of passenger injury and improving safety.

[0021] The retractable ramp structure 20 includes a first-level ramp 21, a second-level ramp 22, a third-level ramp 23, a fourth-level ramp 24, and a fifth-level ramp 25. The fifth-level ramp 25 is retractably and slidably installed within the fourth-level ramp 24. The fourth-level ramp 24 is retractably and slidably installed within the third-level ramp 23. The third-level ramp 23 is retractably and slidably installed within the second-level ramp 22. The second-level ramp 22 is retractably and slidably installed within the first-level ramp 21. The first-level ramp 21 is hinged to the ramp support 10 in a flip-out manner, allowing the retractable ramp structure 20 to be retracted and stored inside the vehicle body.

[0022] Figure 2 This is a cross-sectional view of the primary ramp and the secondary ramp in an embodiment of this utility model.

[0023] like Figure 2As shown, the primary ramp 21 is provided with a first groove 211 that matches the shape of the secondary ramp 22, so that the secondary ramp 22 is slidably disposed in the first groove 211 and can extend or retract within the primary ramp 21. The secondary ramp 22 is provided with first sliding flanges 221 on both sides. The first groove 211 is provided with a first limiting groove 212 that matches the first sliding flange 221. The first sliding flange 221 is slidably disposed within the first limiting groove 212. The first sliding flange 221 is provided with a first limiting protrusion 222 at one end near the primary ramp 21, and the first limiting groove 212 is provided with a second limiting protrusion 213 at one end near the secondary ramp 22. The first limiting protrusion 222 and the second limiting protrusion 213 abut against each other, thereby preventing the secondary ramp 22 from sliding out of the first groove 211, ensuring the structural stability and reliability of the telescopic ramp structure 20.

[0024] A buffer spring 26 is provided between the first limiting protrusion 222 and the second limiting protrusion 213. One end of the buffer spring 26 is connected to the first limiting protrusion 222, and the other end of the buffer spring 26 is connected to the second limiting protrusion 213. The buffer spring 26 can improve the buffering effect during the extension or retraction of the ramp, so that the ramp can extend smoothly and quickly. In case of danger, it can be quickly deployed for emergency evacuation, reducing the possibility of passenger injury and improving safety.

[0025] The telescopic structure between the second-level ramp 22 and the third-level ramp 23, between the third-level ramp 23 and the fourth-level ramp 24, and between the fourth-level ramp 24 and the fifth-level ramp 25 is the same as that between the second-level ramp 22 and the first-level ramp 21. The third-level ramp 23 is provided with a second sliding flange 231 on one side; the fourth-level ramp 24 is provided with a third sliding flange 241 on one side; and the fifth-level ramp 25 is provided with a fourth sliding flange 251 on one side, so that the telescopic ramp structure 20 can extend and retract smoothly, improving the reliability of the structure.

[0026] The first-level ramp 21 is equipped with a support handle 214, which allows the operator to hold onto the ramp and easily flip it over. This enables the second-level ramp 22, third-level ramp 23, fourth-level ramp 24, and fifth-level ramp 25 to extend smoothly and quickly. This allows the emergency evacuation ramps for subway vehicles provided by this invention to be deployed by one person, enabling rapid deployment for emergency evacuation in the event of a dangerous situation, reducing the possibility of passenger injury and improving safety.
