Intelligent assembly and maintenance work vehicle for high-speed EMU

Abstract

The invention discloses an intelligent assembly and maintenance operation vehicle for China railway high-speed. The intelligent assembly and maintenance operation vehicle comprises a vehicle body, wherein a roller shutter door is arranged at the upper part of the vehicle body; two fixed plates are symmetrically arranged on two sides of the roller shutter door; a guiding groove of the roller shutter door is formed in the inner side of each fixed plate; rollers are arranged on the inner side of each guiding groove; an alarm light is mounted outside the fixed plate on the right side; a foldable support is mounted on the platform of the vehicle body; a sleeve selector is arranged at the right side of the foldable support; a first threading hole is formed beside the sleeve selector; a digital display wrench, a constant-moment wrench and an electric wrench are arranged in front of the sleeve selector; a card reader is further arranged in the front of the foldable support; a keyboard and a mouse are placed in a drawer of the vehicle body; an uninterruptible power supply is mounted in the front half part of the interior of the vehicle body; and a second threading hole is formed below an electric switch. The intelligent assembly and maintenance operation vehicle has the error-proof, missing-proof and re-tightening-proof functions, relieves the labor intensity of workers, realizes real-time recording, inquiry and tracking of assembly data and improves the working efficiency and the assembly quality.

Description

technical field [0001] The invention relates to an assembly and maintenance tool vehicle, in particular to an intelligent assembly and maintenance operation vehicle for high-speed EMUs. Background technique [0002] The bolt assembly and maintenance of the existing high-speed EMU components mostly adopt wind trigger pre-tightening + constant torque wrench check type, hanging special tightening equipment along the fixed track, etc., among which wind trigger pre-tightening + constant torque wrench check Manually identify and tighten bolts, which is not only inconvenient to operate, but also has a high probability of wrong assembly and missing assembly in manual identification. The labor intensity of workers is high, the assembly accuracy is low, and workers need to manually fill in a large amount of relevant assembly information, which is time-consuming and laborious. But the recorded information The quantity is extremely limited, and the retrospective query of assembly data c...

[0002] The bolt assembly and maintenance of the existing high-speed EMU components mostly adopt wind trigger pre-tightening + constant torque wrench check type, hanging special tightening equipment along the fixed track, etc., among which wind trigger pre-tightening + constant torque wrench check Manually identify and tighten bolts, which is not only inconvenient to operate, but also has a high probability of wrong assembly and missing assembly in manual identification. The labor intensity of workers is high, the assembly accuracy is low, and workers need to manually fill in a large amount of relevant assembly information, which is time-consuming and laborious. But the recorded information The quantity is extremely limited, and the retrospective query of assembly data cannot be realized; the hanging special tightening equipment can realize the synchronous tightening of fixed torque, but due to the lag of the information system of each unit, the collected and recorded information cannot be stored and uploaded one by one To the server, there is a lack of corresponding process control means, the probability of error is high, and once a quality problem occurs, it is impossible to realize the true meaning of data traceability
