Description

Technical Field

[0001] The present application relates to the field of urban rail transit vehicle maintenance, and in particular to a subway gangway operation auxiliary device. Background Art

[0002] In the subway, a through-pass (also called a through-connector or transition) is a structure that connects two train cars, allowing the two trains to move relatively freely during travel. This connection structure is usually located at both ends of the train, allowing passengers to move freely between trains, while also facilitating the flexible operation of vehicles in the railway system.

[0003] The gangway mainly includes outer windshield, ferry, pedal and side guard. Among them, the outer windshield is composed of bellows, end frame and connecting frame. The bellows helps to adapt to the changes when the vehicle moves and improve the flexibility of the connection. The outer windshield of the bellows, end frame and connecting frame can be balanced and stable when connecting two trains, and can adapt to different operating conditions, ensuring the reliability and safety of the connection. The ferry is located in the connection area to facilitate passengers to transition between the two trains. It provides a flat and safe surface so that passengers can easily cross the gangway. The pedal is located between the vehicles in the connection area, providing a platform for passengers to get on and off the train. It is usually installed between the connecting frame and the end frame to facilitate passengers to enter and exit the train smoothly. Figure 1 This is a schematic diagram of the side guard plate of the prior art preferred by the embodiment of the utility model. Figure 1 As shown, the side guards are installed on both sides of the connection area of ​​the subway vehicle, surrounding the periphery of the entire through-passage. The side guards include: side guards A, middle guards B, connecting rods C and side guard reels D. Side guards A are located on the outside of the side guard assembly, connected to the support at the end of the vehicle through the side guard shaft, and locked by a quick locking mechanism. The middle guard B is located in the center of the side guard assembly, and is composed of an aluminum plate inlaid on the outside of the middle guard frame. Connecting rod C is connected to the two axial ends of the middle guard, and both ends are installed on the side guards. The side guard reel D can be fixed to the vehicle body through a connecting and fixing device to achieve the connection between the one-piece side guard and the vehicle body. The side guards can play a role in safety protection, external decoration, strengthening the overall structure of the through-passage, and preventing foreign objects from entering.

[0004] Due to the importance of the gangway, in order to prevent the failure of the gangway lock to pop out the side guard plate assembly when the train is operating on the main line, which may cause incidents that endanger operational safety due to the failure of the main components of the gangway. It is necessary to require the train's gangway to be disassembled and inspected regularly in the daily maintenance procedures of the train. In the prior art, there are the following problems with the disassembly and assembly of the side guard plates of the gangway: First, since the side guard plate assembly of the gangway is a one-piece structure with a deadweight of more than 100KG, there is no appropriate position for the hand to grab and lift the manual disassembly and assembly operation. The load-bearing operation is only performed by exerting force on some fingers, which exceeds the load-bearing capacity of normal human hands and fingers, and there is an operational risk. Secondly, the side guard plate assembly is fixed by locking the side guard plate shaft with the support assembly installed at the vehicle end. The distance between the vehicle end supports is fixed when the train is stationary. The installation of the side guard plate assembly requires the cooperation of multiple people to adjust the distance between the side guard plate shafts. The side guard plate assembly has a heavy deadweight and is difficult to adjust. Finally, the edge of the side guard plate of the throughway is made of sharp aluminum alloy. During the operation, the workers must put their fingers into the reel of the side guard plate of the throughway before they can carry out the disassembly operation, and workers often suffer injuries caused by scratches on their fingers.
