Abstract

A sliding plug door system for a freight transport multiple unit. The sliding plug door system comprises a door control system, driving mechanisms (11), door leaves (12), and first guide rails (14). The first guide rails (14) are L-shaped guide rails, and the opening direction of the first guide rails (14) faces the door leaves (12). The first guide rails (14) and the driving mechanisms (11) are fixedly disposed on an inner wall (10), directly above a sliding plug door, of a carriage. The driving mechanisms (11) are separately connected to the door control system and the door leaves (12), and the driving mechanisms (11) can slide along the first guide rails (14). The driving mechanisms (11) are used for driving the door leaves (12) to move along the first guide rails (14) according to a control command sent by the door control system. According to the sliding plug door system, during a door opening process, the door leaves (12) swing into a carriage by a distance first and then move along the inner wall (10) of the carriage, so that during the process of opening the door leaves (12), the risk that the door leaves (12) swing outward a train and then fall is prevented. In addition, the driving mechanisms (11) have a compact structure and occupy a small 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...
