Bogie overhauling process and system based on part cleaning center

Abstract

The invention discloses a bogie overhauling process based on a part cleaning center. The bogie overhauling process comprises the following steps: disassembling a bogie to be overhauled into a framework, a wheel set, a traction motor and small parts; transferring the parts to a centralized cleaning center from respective maintenance lines for centralized cleaning; transferring the framework, the traction motor and the wheel set back to respective maintenance lines; sequentially carrying out the flaw detection, shot blasting, measurement, paint spraying and drying maintenance on the framework, the traction motor and the wheel set on the corresponding maintenance lines respectively; assembling the disassembled and overhauled framework, the traction motor, the wheel set part and the overhauledand replaced small part, and completing overhauling of the bogie. The invention further discloses a bogie overhauling system based on the part cleaning center, wheel set cleaning and traction motor cleaning are both moved into the centralized cleaning center for centralized cleaning, cleaning resources and transfer tools can be shared, and the negative influence of traditional cleaning operationon the environment in an overhauling workshop is avoided.

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
