Abstract
The utility model provides a side sliding door of a railway vehicle, which adopts an integrally built-in type door body and a driving mechanism to tightly compress a vehicle door through a revolving bar type air-pressure driving structure instead of a conventional hydraulic driving device, thereby realizing continuity and stability of pressure in the process of compressing and sealing. Good compressing and sealing between the side sliding door and the vehicle door is realized through the adoption air-pressure driving principle, and better sealing performance can be kept under the circumstance of increased differential pressure inside and outside the vehicle door. The side sliding door comprises a door body, a control device used for controlling action state of opening and closing of the door body and a resetting adjustment device which realizes recovery of door body state before action in an opening state. The side sliding door is integrally arranged on the inner side of a vehicle body, and the door body is tightly compressed onto a door frame of the vehicle body through the control device. After the door body is closed, pressure exerted on the door body is maintained through the control device. The control device is provided with a driving part adopting pneumatic outputting, an air-pressure locking part and a magnetic valve which controls air-pressure output to the driving part and the air-pressure locking part.
Description
Technical field
The utility model relates to a kind of architecture advances of rail vehicle side sliding door, adopts novel air pressure driving principle to realize the sealing that compresses between side sliding door and the car body particularly, belongs to mechanical manufacturing field.
Background technology
Follow the significantly lifting of present domestic main line railway, urban light rail traffic operation speed, proposed higher design standard for the safe handling and the structural stability of vehicle ancillary facility.
For the present rail vehicle of the domestic speed per hour that has come into operation more than 380 kilometers/hour, the safe handling of side direction car door and sealing are comparatively crucial.When running at high speed, the inside and outside pressure differential of car body increases, if the side sliding door sealing performance does not reach instructions for use and potential safety hazard will occur or influence vehicle '.
The type of drive of existing side sliding door mainly is hydraulic pressure or oil pressure, the shortcoming of this type of hydraulic pressure pressed sealing device is a pressure transient, be prone to the pressure decline that loine pressure descends and causes seal member after long-time the use, thereby directly have influence on sealability, and along with the increase of the inside and outside pressure reduction of car body, adopt hydraulically powered sealability also to descend thereupon, obviously do not meet the performance requirement of high-speed track vehicle.
In addition, leakage problem easily appears in the pipeline of fluid pressure drive device because of local pressure is excessive, need regularly overhaul or supplementary irrigation hydraulic oil, causes the raising of vehicle operating cost.
The utility model content
Rail vehicle side sliding door described in the utility model, be to solve above-mentioned technological deficiency and problem and take whole built-in Men Tiyu driving mechanism, substitute conventional fluid pressure drive device with rotation rod-type air pressure drives structure, realization pressure ground continues and stablizes in compressing the process of sealing.
Purpose of design of the present utility model is, realizes that by taking the air pressure driving principle good hold down between side sliding door and the car body seals, and still can keep higher sealability under the situation that the inside and outside pressure reduction of car body increases.
Another purpose of design is, compresses in the process of sealing realizing, the tolerance of strength pipeline can be replenished at any time, need not regularly to carry out overhaul of the equipments.
