Train track flaw detection wheel assembly tool and method for assembling train track flaw detection wheels

Abstract

The invention belongs to the technical field of train flaw detection, and relates to a train track flaw detection wheel assembly tool. The train track flaw detection wheel assembly tool is used for assembling flaw detection wheels in an installation groove, and comprises a guide groove, wherein the guide groove is formed outside a train and formed corresponding to the installation groove; and theflaw detection wheels are arranged in the guide groove in a matched and hanging mode and assembled into the installation groove. The invention further discloses a method for assembling train track flaw detection wheels. According to the train track flaw detection wheel assembly tool and the method for assembling the train track flaw detection wheels, on the one hand, the posture problem of staff members is solved, and the problem that force cannot be used caused by supine operation is solved, on the other hand, the problem of the butt-joint between the flaw detection wheels and the installation groove is solved, and the problem that arms cannot exert force, shaking is caused, so that the flaw detection wheels are unable to be quickly pushed into the installation groove is solved; and the locking problem and adjustment problem are further solved, and the problem that the bending deformation of local supporting parts caused by long running of trains is solved, so that the convenience andadjustability of assembly are greatly improved, and the train track flaw detection wheel assembly tool and the method for assembling the train track flaw detection wheels are more practical and moreconvenient to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of train flaw detection, and in particular relates to a train track flaw detection wheel assembly tool and method. Background technique [0002] Flaw detection The flaw detection monitoring of the track by the flaw detection train is a routine safety monitoring for the long-term operation of the track to see if there are potential safety hazards, and it is the basic safety guarantee for various trains. However, the installation position of the flaw detection wheel is designed in the middle of the train wheel. Both the flaw detection wheel and the train wheel run on the guide rail. The distance from the train wheel to the outer edge of the vehicle body is only 500mm, and the distance from the bottom of the train to the sleeper surface is less than 400mm. The installation space is very narrow. Difficulty in installation. [0003] At present, the assembly and disassembly of the flaw detection wheel is carried ...

AI Technical Summary

Problems solved by technology

However, the installation position of the flaw detection wheel is designed in the middle of the train wheel. Both the flaw detection wheel and the train wheel run on the guide rail. The distance from the train wheel to the outer edge of the vehicle body is only 500mm, and the distance from the bottom of the train to the sleeper surface is less than 400mm. The installation space is very narrow. Difficulty installing

[0003] At present, the assembly and disassembly of the flaw detection wheel is carried out by people lying under the flaw detection vehicle. Due to the narrow working space and the heavy flaw detection wheel, the person's posture is limited when screwing the screws under the vehicle. The reason why the detection wheel is relatively heavy is that it is difficult for the arm to hold up the detection wheel and align it with the tightly fitted dovetail groove.

Especially in the cold winter and the hot sun in summer, the labor intensity of the workers is very high in field operations in such an environment, and they have to be replaced many times every time they travel about 800 kilometers.
