Abstract

The invention discloses a built-in sliding plug door system of a high-speed motor train unit. The system comprises a door leaf, a bearing driving mechanism and a pressing and locking device, the bearing driving mechanism is arranged at the top of the door leaf, the pressing and locking device comprises single-point pneumatic pressing and locking devices and a linkage pneumatic pressing and locking device, and the single-point pneumatic pressing and locking devices are arranged on the two sides of an inlet of the vehicle body; the linkage pneumatic pressing and locking device comprises an upper linkage pressing and locking device and a lower linkage pressing and locking device which are arranged at the upper end and the lower end of the door leaf respectively. Multi-point locking is achieved through the pressing and locking device, the door system is prevented from deforming in the working process, and the safety and the sealing performance of high-speed running of the train are guaranteed; a 90-degree plugging and pulling mode is adopted, and plugging and pulling adjustability is achieved.

Description

technical field [0001] The invention relates to the field of high-speed train traffic, in particular to a built-in plug door system for high-speed train sets. Background technique [0002] With the rapid development of the rail transit field, high-speed trains run at a high speed, which requires higher safety requirements for the door system. In order to meet the loading and unloading of large boxes or objects, there is also a greater demand for the opening of the high-speed train door leaf. When the door leaf opening is large, the size of the door leaf is usually large, and the safety and airtightness of the door system during high-speed operation and the deformation generated when the door leaf is closed cannot be guaranteed; in addition, the built-in doors of existing trains cannot Satisfy the requirement of larger Sierra quantity. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to prov...
