Description

Front-end extending type through channel of railway passenger car Technical Field The invention relates to the technical field of railway passenger car through channels, in particular to a front-end extending through channel of a railway passenger car. Background The connection between trains in the basic consist has not yet been used for a mature front (end) through-passage. The current state is that the same train consisting of two trains is separated from each other. Personnel cannot communicate with each other. If want to go to the tail car from first carriage and need transfer at the platform, therefore the tip setting of two rows of marshalling in prior art is dismantled the structure of connection, when the carriage need be connected to other carriages, can carry out operation such as freely combined's ligature, uncoupling with the help of dismantling the structure of connection, and the through-channel on the railway carriage is usually carried out in the mode of manual work promotion concatenation when ligature, uncoupling, and because through-channel self weight is great, the manual work is ligature, uncoupling is too loaded down with trivial details, has promoted the cost of ligature, uncoupling. Disclosure of Invention The invention aims to provide a front-end extending through channel of a railway carriage, which can meet the requirement of a through channel of the same train, wherein the through channel is simply connected and disconnected and communicated between two trains. In order to achieve the above purpose, the main technical scheme adopted by the invention comprises the following steps: a front-end extension-type through passage for a railway carriage, provided at an end of a carriage body, comprising: The folding type movable folding type automobile comprises a fixed channel fixedly arranged at the end part of an automobile body and a movable channel movably arranged in the fixed channel, wherein a folding shed body is fixedly arranged at the end part of the movable channel at the end part of the automobile body, a folding shed connecting frame is fixedly arranged on the folding shed body, a locking frame assembly is fixedly arranged at the end part of the other automobile body, the folding shed connecting frame is detachably connected with the locking frame assembly, a driving assembly and a guide rail assembly are arranged in the fixed channel, and the driving assembly drives the movable channel to move along the guide rail assembly relative to the fixed channel.
