Dual-purpose pedal used for passengers to get on or off train and provided with rack

Abstract

The invention disclosed a dual-purpose pedal used for passengers to get on or off a train and provided with a rack and belongs to the technical field of auxiliary equipment for trains. According to the technical scheme, the pedal is characterized in that a foot pedal is controlled to be pushed out or retracted through meshing of a rotating shaft gear and the rack arranged at the bottom of the foot pedal, the torque of the rotating shaft gear is increased by means of a transmission, a servo motor is controlled to stop by a travel switch, transition between push-out and retraction of the foot pedal is completed through rear guide rollers, a microprocessor in a control circuit is used for determining the type of a platform according to a distance signal measured by an infrared distance measurement circuit, and further, travel of the foot pedal is controlled. The dual-purpose pedal can be simultaneously applied to a high platform and a low platform and brings convenience to the passengers when the passengers get on or off the train through the high platform and the low platform, and safety accidents are avoided; meanwhile, the efficiency of the passengers getting on or off the platform is improved, and dwell time of the train is saved to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of train auxiliary equipment, and in particular relates to a dual-purpose pedal for getting on and off a train with a rack. Background technique [0002] At present, the platform of the railway station is divided into two types: low platform and high platform. The platform floor of the low platform is 70-80cm away from the floor of the train carriage, and the step for getting off the train on the low platform is three steps. The height difference between adjacent steps The height is 25-30cm, it is very difficult for passengers to get on the bus, and it is very easy to step on the air when getting off. However, there is a gap of 30cm between the heightened high platform and the railway station platform. Each car of the train is equipped with a manual train door pedal. Considering that there are many people using it, the manual train door pedal must be durable. Material is made, causes pedal mass to be too he...

[0002] At present, the platform of the railway station is divided into two types: low platform and high platform. The platform floor of the low platform is 70-80cm away from the floor of the train carriage, and the step for getting off the train on the low platform is three steps. The height difference between adjacent steps The height is 25-30cm, it is very difficult for passengers to get on the bus, and it is easy to step on the air when getting off the bus

However, there is a gap of 30cm between the heightened high platform and the railway station platform. Each car of the train is equipped with a manual train door pedal. Considering that there are many people using it, the manual train door pedal must be durable. It is made of high-speed materials, which causes the pedals to be too heavy, causing heavy physical labor for the conductors, which is particularly incompatible with the rapid development of the social status quo.
