[0002] With the development and progress of engineering machinery design and manufacturing technology, the demand for high-alloy steel track shoes for mining machinery has increased significantly, and the technical and quality requirements have been continuously improved. Track shoes are one of the chassis parts of engineering machinery, used in excavators, bulldozers, etc., and are important parts for manufacturing to withstand impact and high loads.

[0003] For example, the patent with application number CN201010528050.9 discloses a track shoe, including a base plate, a connecting pin ear, an engaging block, a support block and a guide block, wherein the connecting pin ears are fixed on both sides of the base plate; the engaging block is arranged in the middle of the base plate; the support block is arranged on the base plate and is located on both sides of the engaging block; the guide block is arranged at one end of the support block close to the engaging block; the top of the engaging block is arc-shaped, and the contours on both sides are symmetrically arranged, which are a combination of straight lines and curves from top to bottom; the upper surface of the guide block is a horizontal plane, and an inclined surface is connected to both sides of the upper surface.

When installing the hinge shaft, the present solution adjusts the positions of the two plates by abutting against the truncated cone hole for guidance, so that the hinge shaft can be installed when the hinge holes are not fully aligned.

[0012] Preferably, two lifting holes are provided on the top surface of the bottom plate of the plate body, and the lifting holes include a circular hole in the middle and a plurality of strip holes of different lengths extending radially outward from the circular hole. The lifting holes are used to assist lifting, and a lifting head with a cross fork is inserted into the circular hole and the strip hole, and then rotated at a certain angle for lifting.
