Self-adaptive telescopic footboard device for train platform

Abstract

The invention relates to a self-adaptive telescopic footboard device for a train platform. The self-adaptive telescopic footboard comprises an installation support which is horizontally and fixedly installed in the platform. An opening is formed in the side, close to a compartment, of the installation support. A telescopic footboard is linked in the opening through a driving assembly. The two sides of the installation support are each provided with at least one high-precision laser ranging sensor. The laser ranging sensors are in communication connection with a signal controller installed inside the device. The signal controller can obtain opening and closing signals from the platform or a shielding door or an independent controller, and when a train draws up at a station, laser ranging is conducted, the footboard stretches out automatically after the train is stopped completely; and when the train leaves the station, laser ranging is stopped, and the footboard retracts automatically. The self-adaptive telescopic footboard device for the train platform is reasonable in design, safe and reliable; multi-point laser ranging is adopted, measurement values are compared automatically, and the stretching-out length of the footboard is controlled automatically by means of an interface circuit through a servo driver so that the footboard device can adapt to different gap dimensions between existing platforms and trains, the safety of passengers when the passengers take on and take off the trains can be effectively guaranteed, and scratching between the footboard and the compartment can be prevented; and the trains can operate efficiently, safely and automatically.

Description

technical field [0001] The invention relates to a train platform adaptive telescopic pedal device, in particular to a platform self-adaptive telescopic pedal device for urban rail transit trains such as subways and high-speed rails, belonging to the technical field of urban rail transit and passenger trains. Background technique [0002] The rapid development of urban rail transit and passenger train technology, including subways and high-speed rails, has greatly facilitated the travel of passengers. When the train is running, the body will sway slightly, and there is also a tilt radius when turning. If there is no gap between the platform and the train, the train will inevitably collide with the platform and scratch the body when it enters the station, affecting the normal operation of the train. , so a certain gap must be left to ensure the safety of the train. The size of this gap is generally 80-380mm in the straight line section, and generally not greater than 380mm in...

AI Technical Summary

Problems solved by technology

The size of this gap is generally 80-380mm in the straight section, and generally not greater than 380mm in the curved section. The existence of this gap may cause passengers to accidentally drop objects when getting on and off the train, and even passengers may fall into the gap and cause personal injury.

At present, some platforms adopt the method of installing rubber pads to solve this problem, but the actual effect is not ideal. Due to the construction differences of various types of trains and platforms, there are still large gaps. Generally, the thickness of rubber pads is fixed at 50- 80mm, the hidden dangers of passengers’ personal safety and item loss still exist, and the rubber is easy to age, and needs to be replaced according to a certain period.
