Description

Technical Field

[0001] The utility model relates to the technical field of anti-loosening markings for rail transit vehicles, in particular to a device for applying anti-loosening markings on large bolts of rail vehicles. Background Art

[0002] At present, in the rail vehicle manufacturing industry, the tightening and anti-loosening of bolted connections in the structure of large mechanical equipment involved in assembly is crucial for vehicle driving safety. The traditional marking method is for the operator to use a marking pen to mark the screw cap with one hand (see the vehicle structure diagram for details). Figure 1 As shown), the screw cap is painted with a length of 4-10mm according to the size range, and the painted line is carried out along the outside of the bolt body until it reaches a length of 4-10mm on the vehicle structure. The marking line thickness should be uniform and the line width should be 2-3mm according to the size. The above marking method has the following defects:

[0003] 1) Inaccurate marking. Due to the influence of vehicle structure, most bolts are not on the surface. Due to the manual marking process, the length of the marking on the screw cap and the vehicle structure cannot meet the 4-10mm size range required, resulting in inaccurate marking.

[0004] 2) The marking is not easy to observe. Due to the influence of factors such as the operator's own construction techniques and some employees' left-handedness, the anti-loosening marks applied by the employees are not completely consistent;

[0005] 3) Uneven marking. Due to manual operation and the fact that most large vehicle parts are hoisted parts, workers need to lie on their backs with one hand suspended in the air when marking bolts to prevent loosening. This results in the marking not being able to meet the marking line thickness of 2-3mm, and uneven marking often occurs. Utility Model Content

[0006] The purpose of the utility model is to overcome the defects of the existing technology and provide a device for applying anti-loosening marks on large bolts of rail vehicles, which facilitates the anti-loosening marking work of large bolts, ensures that the anti-loosening marks are safely, reliably and neatly applied on the fastening bolt bodies, eliminates the problems of inaccurate, uneven or inconvenient marking, improves the quality of anti-loosening marks on large bolts, and facilitates subsequent construction inspections by staff.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:
