Installation method of rail vehicle electrical cabinet enclosure

Abstract

A method for installing the electrical cabinet enclosure of a rail vehicle, the main steps are as follows: the main structure of the electrical cabinet enclosure is assembled under the vehicle, and positioning pins are used to ensure that the spring adjustment mechanism is in a compressed state; the guide groove and the first connecting piece are installed on the vehicle Specify the position; push the electrical cabinet enclosure along the direction of the guide groove, so that the electrical cabinet enclosure is inserted into the first connector; fix the enclosure to the vehicle floor and vehicle partition through the second connector and the third connector; pull out the spring Adjust the positioning pin on the mechanism, the base springs up under the action of the spring and touches the roof of the vehicle, then connects the base to the roof of the vehicle with screws, and inserts the positioning pin into the second pin hole and the top pin hole of the hoarding frame; press The rotating panel of the spring adjustment mechanism makes the inner surface of the rotating panel closely contact with the adhesive buckle on the front of the enclosure frame; so far, the installation of the enclosure panel of the electrical cabinet is completed. The installation method of the present invention is particularly suitable for the installation of the enclosure of the electrical cabinet in a narrow space, the installation method is simple, and the installation efficiency is high.

Description

technical field [0001] The invention relates to the installation and fixing of the coaming plate of the electrical cabinet of a railway passenger car, and belongs to the technical field of railway passenger cars. Background technique [0002] In order to ensure the safety of passengers and the appearance of the electrical cabinet on the railway passenger car, the electrical cabinet enclosure is usually installed outside the electrical cabinet. The installation process adopts the order of first installing the electrical cabinet and then installing the electrical cabinet enclosure. In order to ensure the simple and beautiful appearance and structure of the hoarding, the installation of the hoarding usually adopts internal connection, that is, the installation point is placed between the electrical cabinet and the gap between the hoarding, so that the connecting parts and mounting screws can be hidden; With the development of high-grade and humanized direction, more and more tr...

Problems solved by technology

In order to ensure the simple and beautiful appearance and structure of the hoarding, the installation of the hoarding usually adopts internal connection, that is, the installation point is placed between the electrical cabinet and the gap between the hoarding, so that the connecting parts and mounting screws can be hidden; With the development of high-grade and humanized direction, more and more train functions, the internal equipment of the electrical cabinet is also gradually increasing, and the size of the electrical cabinet is also increased accordingly. However, due to the overall layout and space problems of the train, the size of the outer electrical cabinet enclosures should be controlled as much as possible However, the space between the enclosure and the electrical cabinet is getting smaller and smaller. If the enclosure of the electrical cabinet is still installed in the traditional way, the operating space is too narrow when the enclosure is installed, and even some parts cannot be accessed by installation tools. Workers cannot operate, resulting in the phenomenon that the final electrical cabinet enclosure cannot be installed normally
