Sliding plug door system used for freight transport motor train unit

Abstract

The invention provides a sliding plug door system used for a freight transport motor train unit. The sliding plug door system comprises a door control system, drive mechanisms, door leaves and first guide rails. The first guide rails are L-shaped guide rails, and the opening direction of each first guide rail faces the corresponding door leaf. The first guide rails and the drive mechanisms are fixedly arranged on the inner wall, right above a sliding plug door, of a carriage. The drive mechanisms are connected with the door control system and the door leaves and can slide along the first guide rails. The drive mechanisms are used for driving the door leaves to move along the first guide rails according to a control command sent by the door control system. By the adoption of the sliding plug door system, in the door opening process, the door leaves swing into the carriage for a center distance firstly and then move along the inner walls of the carriage, and the risk that the door leaves swing outwards in the door leaf opening process and then fall is prevented. Meanwhile, the drive mechanisms of the embodiment are compact and relatively small in occupied inner space of the carriage, and therefore the available space of the carriage is increased.

Description

technical field [0001] The present invention relates to mechanical technology, and in particular to a sliding door system for a freight car unit. Background technique [0002] With the rapid development of the economy, it is a trend of railway express freight services to use high-speed EMUs to transport bulk and high value-added goods. Therefore, how to provide a kind of sliding door with a large opening becomes the focus of technical personnel's research. [0003] The existing external plug door structure mainly consists of a driving mechanism, left and right door leaves, lower guides (the lower swing arm assembly and the sliding groove of the door leaf), internal and external emergency operating devices and door pedals. Among them, the thickness of the door leaf is generally less than 32mm, and the interior is generally filled with aluminum honeycomb or paper honeycomb for sound insulation and heat insulation. The lower part of the door leaf is provided with an isolation...
