Description

Assembly line for electrical control cabinet of railway passenger car Technical Field The utility model relates to the technical field of railway carriages, in particular to an assembly line of an electric control cabinet of a railway carriage. Background Along with the rapid development of the railway transportation industry, the production scale of the electric control cabinet of the railway carriage is continuously enlarged, and higher requirements are put on the efficiency and the adaptability of the assembly line. However, the existing assembly line of the electrical control cabinet of the railway carriage has a plurality of defects. On the one hand, the traditional assembly line adopts a working platform with a fixed height, when the electric control cabinets with different specifications are assembled, workers need to frequently adjust the postures of the workers or finish the operation by means of auxiliary tools, so that the labor intensity is increased, misoperation is easily caused, and the assembly quality and the assembly efficiency are influenced. For example, when assembling a higher-sized electrical control cabinet, a worker needs to bend down to operate, which is prone to physical fatigue for a long period of time, and when assembling a shorter-sized control cabinet, the worker needs to raise his/her arm, which also reduces work efficiency.
