Shielding door cab apron placing device for rail transit

Abstract

The invention relates to the technical field of rail transit, and discloses a rail transit platform screen door cab apron placing device. The device comprises a base, a platform screen door and a vehicle door; sliding blocks are symmetrically installed on the two sides of the platform screen door, sliding sleeves are fixedly connected to the lower ends of the sliding blocks, and threaded rods are connected to the inner sides of the sliding sleeves in a sleeving mode; the tail end of the threaded rod is fixedly connected with a first gear, the first gear is meshed with a second gear, and the left side of the second gear is fixedly connected with a cab apron. Rotary placement of the cab apron is automatically achieved by opening the shielding door, the effect of automatically placing the cab apron is achieved, and the problems that manpower and material resources are consumed when workers manually place the cab apron, and the taking efficiency is low are solved; meanwhile, through cooperative arrangement of a limiting rod, a limiting rod, a conducting strip and an electromagnet, upward movement of a limiting plate is achieved, then the effect of preventing the wheels from slipping backwards is achieved, the problem that in the prior art, due to the fact that the cab apron is obliquely placed, the wheels slip backwards is solved, and the riding safety of passengers is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a device for placing a transition plate of a screen door for rail transit. Background technique [0002] In the operation of rail transit, there are often passengers with limited mobility. When taking the subway, staff are required to place the ferry board between the screen door and the car door to facilitate passengers who use wheelchairs or push baby carriages. When it is necessary to use the ferry board Passengers should first contact the platform staff and place the board before boarding. This method is inefficient, and most of the time it is impossible to contact the staff at the first time, and the best boarding time may be missed, which will affect the travel plan of passengers; Secondly, due to the slow movement of people with disabilities during the boarding process using the ferry board, if the screen door is closed during the boarding process, passengers will be ...
