Railway track train and train door entrance step structure thereof

Abstract

The invention discloses a railway track train and a train door entrance step structure thereof, the train comprises a fixed step fixed on a train body and close to the bottom of the train; a telescopic step forming a continuous step with the fixed step, wherein the telescopic step is far away from the train bottom and comprises a step body fixed to the train body and a movable pedal capable of extending out of the step body, and when the train is in butt joint with the high platform, the movable pedal extends out of the step body to make up for a gap between the step body and the high platform; when the train is in butt joint with a low platform or no platform, the movable pedal retracts to the step body; when the train is in a door closing state, the movable pedal extends to a door closing position to compensate a gap between the step body and a train door leaf; and the train further includes a driving device which drives the telescopic position of the movable pedal. Movement of the movable pedal is controlled through the driving device, and manual operation is replaced. The train door entrance step structure can adapt to platforms with different heights, passengers are preventedfrom falling into gaps, manual operation is not needed, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of railway track trains, in particular to a railway track train and its train door entrance step structure. Background technique [0002] EMU trains run on the line, and the platforms they pass will have high platforms (platform height 1050mm), low platforms (platform height 400mm), and even some stations do not have platforms (platform height 0). [0003] In order to ensure that the entrance of the train is matched with the platform for passengers to get on and off the train, the existing train has three fixed steps in the entrance area. When the platform is high, there is a large gap between the vehicle and the platform, and there is a risk of passengers falling into the gap. In view of this, at present, a manual cover plate is used to cover the next level of steps to adapt to platforms of different heights. However, manual operation is required when opening or closing the door. Therefore, each carriage mu...

Problems solved by technology

In view of this, at present, a manual cover plate is used to cover the next level of steps to adapt to platforms of different heights. However, manual operation is required when opening or closing the door. Therefore, each carriage must be manually operated by a conductor, which is labor-intensive.
