Hinge pin for loading machine

Abstract

The invention relates to a hinge pin for a loading machine. The hinge pin for the loading machine comprises a hinge pin body, wherein two ends of the hinge pin body are of a conical structure, and an upper conical sleeve and a lower conical sleeve which are matched with the conical structures of the two ends are correspondingly arranged at the conical structures of the two ends, and an upper end cover and a lower end cover are arranged at the outer sides of the conical sleeves at the two ends of the hinge pin body; the upper conical sleeve and the lower conical sleeve are open conical sleeves; and the taper between the hinge pin body and the corresponding end of the upper conical sleeve is less than that between the hinge pin body and the corresponding end of the lower conical sleeve. The \ fit between the conical sleeves of the hinge pin for the loading machine and a body pin / pin hole of the loading machine can be properly adjusted through the conical structures at the two ends of the hinge pin body as well as the conical sleeves and the end covers matching with the conical sleeves so as to maintain the close fit between the hinge pin (conical sleeves) and the pin hole all the time, so that the problems of fracture of bolts and damage of the body hole caused by the displacement of the hinge pin during working is totally avoided; and simultaneously the hinge pin is very convenient to mount as size of the hinge pin body is less than the size of the hole.

Description

technical field [0001] The invention relates to a connection part of a loader, in particular to a hinge pin part of a loader Background technique [0002] The existing loader uses a columnar hinge pin to connect the fuselage and the machine head. Since the loader is heavily loaded during work and the hinge pin is at the center of the load, the gap between the hinge pin and the pin hole / body hole There will be wear and tear to form a gap, so that the hinge pin will generate an upward movement force during the work process. The upward movement force will break the lower bolt fixing the hinge pin, resulting in damage to the loader or engineering accidents. Therefore, at present, most of the loaders will replace the hinge pins after working for a period of time. If the pin holes are severely worn, the connecting components at this position must be cut and repaired. And because the location of the hinge pin and the pin hole is narrow, the operation of dismantling and repairing i...

AI Technical Summary

Problems solved by technology

[0003] In view of the above problems, a loader hinge pin with a taper is designed, which solves the problem that the hinge pin moves upwards and breaks the lower bolt and damages the fuselage hole due to the use of columnar hinge pins in the existing loader.
