Description

Technical Field

[0001] The utility model relates to the technical field of rail transit emergency evacuation equipment, in particular to a subway tunnel evacuation platform penetration device. Background Art

[0002] The evacuation platform is an emergency evacuation channel in the subway tunnel.

[0003] An evacuation platform is a dedicated passageway within a subway tunnel, typically at the same height as the station platform, designed for evacuating passengers. In the event of an accident in the tunnel, passengers can reach the evacuation platform via the evacuation passageway beneath the train car, allowing them to quickly escape the incident and reach the emergency exit safely.

[0004] Subway evacuation platforms play a vital role in the subway system, especially in emergency situations, and are of great significance in ensuring the safety of passengers.

[0005] The evacuation platform must be disconnected at the section civil air defense doors, flood control doors, platform ends, and connecting passages, with a down-track ladder connected to the trackbed. Disconnection at the civil air defense doors ensures they are not blocked when closing; disconnection at the flood control doors ensures they are not blocked when lowering from the tunnel top; disconnection at the platform ends facilitates station personnel descending from the platform to the trackbed for various construction and maintenance tasks; disconnection at the connecting passages allows for connectivity between the up and down sections, ensuring smooth movement of construction workers or evacuees.

[0006] The above aspects all take into account the passage of personnel through the track bed. However, when water accumulates in the section and personnel cannot pass through the track bed, they must use the evacuation platform for evacuation. If the evacuation platform is disconnected at this time, it will not be able to evacuate personnel.

[0007] Currently, there are two ways to implement the evacuation platform connection device: built-in type and zipper suspension type. The built-in type is to hide the connection device under the existing evacuation platform, and the cable suspension type is to achieve the lifting and lowering of the track ladder through pulleys and cables, so that the pulled-up evacuation platform is basically level with the original evacuation platform.

[0008] Although the built-in evacuation platform has supports, they are not fixed to the ground, posing a risk of lateral movement. There is also a height difference between the built-in platform and the existing evacuation platform. The platform cannot resolve the problem of interpenetration at the platform ends, flood prevention doors, and civil air defense doors. When the zipper-suspended evacuation platform is pulled up, there are no fixings at either end to secure it, posing a risk of lateral movement. There is also a height difference between the pulled-up platform and the existing evacuation platform. The platform cannot resolve the problem of interpenetration at the platform ends, flood prevention doors, and civil air defense doors. There are no lower supports, and only two cables are used to bear the weight of people. Without lower supports, collapse may occur. The cables are set against the tunnel wall, and there is only one cable at one end. There is no cable on the side close to the train, making it prone to rollover. Utility Model Content

During the rotation of guide rail 71, it pushes sliding member 75 to slide upward along top column 63 or support column 74. Top column 63 and support column 74 disengage from the groove of the diagonal support angle 62. The sliding member 75 located above slides in the guide rail 71, driving the adjacent step 73 located below to move. Driven by the sliding member 75, the step units gradually slide upward, close together, and splice into a flat surface. After hydraulic cylinder 72 drives telescopic stair mechanism 5 to move, hydraulic rod 42 drives lifting platform mechanism 1 to rise.
