Problems solved by technology

However, during the actual operation of the locomotive, due to the bumping and vibration of the locomotive, the male pin will rotate around its pivot axis. When the male pin and the female pin form a straight line, the bending pin will come out of the brake shoe support. If it is not found in time during the temporary inspection, it will further lead to the detachment of the brake shoe, which will lead to the loosening of the brake shoe and cause a general category C accident of railway locomotives.

Abstract

The invention discloses an anti-falling folding pin and belongs to the technical field of locomotive inspection and repair. The anti-falling folding pin comprises a male pin, a female pin and an anti-falling part. The male pin and the female pin are pivoted and fixed through a pivot shaft. The anti-falling part is arranged at the end, far away from the pivot shaft, of the male pin. The anti-falling part is detachably connected with the male pin. The anti-falling folding pin can effectively prevent looseness of a brake shoe, avoids occurrence of locomotive accidents, ensures safe and stable operation of a locomotive and is simple and reliable in structure and easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of locomotive maintenance, and in particular relates to an anti-off bending pin. Background technique [0002] At present, the brake shoe tags of locomotive units such as DF8B use bending pins to prevent them from coming off. The bending pins are composed of a male pin and a female pin that are pivotally fixed to each other. The male pin is folded down and locked. However, during the actual operation of the locomotive, due to the bumping and vibration of the locomotive, the male pin will rotate around its pivot axis. When the male pin and the female pin form a straight line, the bending pin will come out of the brake shoe support. If it cannot be found in time during the temporary inspection, it will further lead to the detachment of the brake shoe sign, thereby causing the brake shoe to loosen, forming a general category C accident of railway locomotives. Contents of the invention [0003] In order to o...
