Railway motor trolley power-driven bi-parting sliding plug door system

Abstract

The present invention relates to an electric dual-opened plug door system for a track train, and has the structure that a loading driving mechanism is positioned at the upper part of the train body; a door leaf is connected with the loading driving mechanism through a holding door frame; transmission shafts at the two sides of the train door are connected with the small hanger of the loading driving mechanism through flaps, and then arranged at the two sides of the train body after being connected with a locking device at the middle-lower part of the train door; a roller in a lower swing arm device is arranged in a lower lead rail at the lower part of the train door; an external operational device and an emergency operational device which is arranged at the inner side of the train body are connected with the locking device through steel cables; the lock rail of the door leaves is arranged to match the lock hook on the locking device; the present invention has the advantages that the multi-class locking device strengthens the safety and the reliability of the train door system; through adopting the square lead rail and the slide block loading mechanism, as well as the cross coordinate working manner formed by square lead rails and short lead pillars, the structure of the loading device is compact and the loading capability is improved, and the installation, adjusting and maintenance of the loading device are easy and convenient. The present invention meets the demands of the high speed, safety, reliability, sealing, and sound and heat insulation for the door system of the intercity railway transportation.

Description

technical field [0001] The invention relates to an electric double-opening plug-and-pull door system for rail trains, which belongs to the technical field of railway transport machinery. Background technique [0002] At present, the load-bearing structure of the rail train electric double-opening sliding door system mainly has two forms, one is a single guide post form, and the other is a double guide post form. The bearing mechanism of the plug-and-pull door in the form of a single guide post is relatively long, occupying a relatively large length and space of the car body, which is larger than the width of the door frame of the plug-and-pull door; bigger. At present, the locking devices of these two forms of double-opening electric sliding doors are all arranged on the bearing mechanism, and the locking system is realized by the locking mechanism. This locking form can only meet the requirements of low-speed vehicles. With the rapid development of social economy, the exi...

Problems solved by technology

With the rapid development of social economy, the existing intercity railway passenger transportation mode can no longer meet the needs of the society, and the intercity railway passenger transportation is developing towards public transportation and rapid development, which requires the improvement of the pleasantness, reliability and safety of the sliding doors sex

The passenger flow of intercity passenger transport is relatively large, and the flow of passengers getting on and off the train increases accordingly. Therefore, it is necessary to increase the number of doors in each carriage and increase the opening of the door. Performance, heat insulation performance, safety and reliability put forward higher requirements, increasing the technical difficulty of the door system
