A bogie maintenance process and system based on parts cleaning center

Abstract

The invention discloses a bogie overhaul process based on a parts cleaning center, which comprises the following steps: dismantling the bogie to be overhauled into a frame, a wheel set, a traction motor and small parts; and transferring them from respective overhaul lines to centralized cleaning Centralized cleaning at the center; transfer the frame, traction motor, and wheel set back to their respective maintenance lines; perform flaw detection, shot blasting, measurement, and painting on the frame, traction motor, and wheel set in sequence on the corresponding maintenance line and drying overhaul; assemble the dismantled and overhauled frame, traction motor, wheel set components, and small parts after overhaul to complete the overhaul of the bogie. The invention also discloses a bogie overhaul system based on the component cleaning center. The wheel set cleaning and the traction motor cleaning are both moved to the centralized cleaning center for centralized cleaning, which can share cleaning resources and transfer tools, and avoid the traditional cleaning operation from affecting the maintenance workshop. negative impact on the environment.

Description

technical field [0001] The invention belongs to the technical field of bogie inspection and repair of high-speed railway EMUs, and is also applicable to the technical field of ordinary railway trains, urban rail transit vehicles, etc., which require bogie inspection and repair. More specifically, it relates to a bogie inspection process based on a component cleaning center and system. Background technique [0002] The high-speed rail EMU bogie is one of the most important components of the high-speed rail EMU. It has the functions of supporting, steering, driving and braking at the same time during the high-speed operation of the train, and it always bears the horizontal, vertical and vertical loads. load. Under such complex working conditions of high speed and heavy load, reliable bogie maintenance is the key link to ensure its safe operation. [0003] At present, the maintenance process of the bogie of the high-speed rail EMU is to disassemble the bogie into components a...

Problems solved by technology

[0004] However, there are many disadvantages in the above-mentioned traditional maintenance process. The main reasons are: first, the cleaning operation is carried out directly in the component maintenance line of the bogie maintenance depot, and the sewage and cleaning chemicals generated during the cleaning process have an impact on the working environment of the entire bogie maintenance workshop. The second is that the cleaning operation is mainly manual cleaning, and the labor intensity of the operators is relatively high; the third is that the process backflow often occurs because the cleaning quality does not meet the requirements of the next process, which affects the maintenance efficiency of the maintenance line, thus restricting Improve the maintenance efficiency of the whole bogie
