Problems solved by technology

After the introduction, due to the small amount of maintenance and the limited space, the maintenance equipment of the domestic main engine factory is mainly guided by the situation. and overhaul mode is only for one bogie design
(3) Maintenance data is manually recorded, with large human errors, unable to realize data automation between stations, disordered maintenance, poor controllability, easy to simplify repairs, illegal repairs, missed repairs, etc.
(4) The form of logistics adopts manual handling, which is labor-intensive and low-efficiency
(5) The maintenance data management is still the traditional paper-based data archiving, which is easy to be lost, omitted, damaged, and difficult to archive for long-term preservation
(6) The maintenance efficiency is low and the maintenance quality is poor, which cannot meet the needs of high efficiency, high quality and data automation in the industry

Embodiment Construction

[0034] The running water maintenance method of the EMU framework of the present invention comprises the following steps:

[0035] 1. Shock absorber decomposition

[0036] At the frame and wheel set separation station, the decomposed frame is hoisted by a fixed frame crane to the AGV frame transport vehicle. The height of the AGV car support bracket is 1200mm, and the height of the frame support is suitable for manual maintenance. The operator presses the button on the AGV, and the AGV carries the frame and enters the frame maintenance line automatically. After arriving at the shock absorber disassembly station, it automatically locates and stops. At this station, the axle box shock absorber on the frame is disassembled by a pneumatic trigger. , Vertical shock absorber, transverse shock absorber. The various shock absorbers that have been disassembled are transferred to the storage rack using a combined jib crane. CRH2, CRH3, CRH5 vehicles disassemble and repair similar parts...

Abstract

The invention provides a motor train unit framework flow line maintenance system capable of intelligently maintaining various motor train unit frameworks of CRH (china railway high-speed) series in a high-efficient and high-quality manner and a maintenance method thereof. The motor train unit framework flow line maintenance system comprises a damper decomposition system, a first framework turning system, a brake caliper decomposition system, a tie and torsion bar decomposition system, a framework flaw detection paint maintenance system, a tie mounting system, a torsion bar mounting system, a second framework turning system, a damper mounting system and a draw bar mounting system which are sequentially connected. The motor train unit framework flow line maintenance system is integrated, various scattered stations are reasonably arranged to form a flow line, maintenance process is in a flow line operation manner, and accordingly labor intensity of an operator is lowered, chain mutual controlling, functioning, automation and high-efficiency among the stations are achieved by intelligent logistics.

Description

technical field [0001] The invention relates to a rail vehicle maintenance system and a maintenance method thereof, in particular to a train frame flow-water maintenance system and a maintenance method thereof. Background technique [0002] The EMU bogie is the power drive part of the high-speed EMU train, and it is also an important part to stably bear the weight of the car body. For the safety of trains running at high speed, it is necessary to overhaul the bogies of the EMU, and the quality of the overhaul directly affects the stability and safety of the EMU train operation. [0003] Before the introduction of EMUs in China, there was still a gap in the maintenance of EMUs in China. After the introduction, due to the small amount of maintenance and the limited space, the maintenance equipment of the domestic OEMs has been optimized. and overhaul mode are only for one bogie design. (2) Adopt positioning repair, scattered layout, and extensive process flow. (3) Maintena...
