Description

Portable supplementary ladder of boarding

Technical Field

The invention relates to the technical field of subway train boarding ladders, in particular to a portable auxiliary boarding ladder.

Background

When a front car is simulated to have a fault in the process of multi-point passenger propulsion drilling of a subway train, a driver of a rear car needs to board the front car for disposal according to the requirements of an emergency plan, and the situations that the driver is difficult to board and cannot board the front car smoothly in the drilling process often occur.

The reason for this is that: the boarding ladder of the original cab takes the possibility of avoiding the limit invasion in the operation into consideration, the ground clearance of the lowest layer of pedals is 450mm, and if the boarding ladder is in a positive line interval and the height of a track bed is added, the ground clearance of the lowest layer of pedals reaches 650 mm; and the lowest layer of pedal of the original design is recessed 250mm towards the vehicle body in order to avoid the possible invasion limit, so that the gravity center of the human body is shifted when a driver uses the original boarding ladder to board the vehicle, and potential safety hazards exist.

In order to solve the difficulty of boarding of a driver and ensure that the driver can get on the vehicle quickly and safely, a portable auxiliary boarding ladder is provided.
