Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 5, the traveling wheels 7 are arranged in the box body, the wheel shafts on both sides are respectively supported by bearings 10 which are arranged on the front and rear side plates 8 of the box body in a close fit manner, the wheel shafts and the bearings 10 are also in close fit, the front and rear side plates 8 have the same structural form and are respectively fastened with the left and right side plates 8 of the box body through bolts, and a pair of first positioning screw holes 9 which are symmetrically arranged on the left and right sides of the bearings 10 are arranged on the outer plate surface of the front and rear side plates 8 of the box body.

Referring to fig. 1 to 4, the special dismounting tool for a box body of a shuttle car traveling wheel 7 of the present embodiment includes a planar base 1 having a pair of second positioning screw holes 2 and a screw rod 4 threaded through the middle portion of the planar base 1, the pair of second positioning screw holes 2 are disposed corresponding to the external dimensions according to the position distribution of the pair of first positioning screw holes 9, and are disposed on the left and right sides of the screw rod 4 symmetrically, one end of the bottom surface of the planar base 1 protrudes outward along the axial direction of the screw rod 4 to form a positioning boss 3, the position of the screw rod 4 relative to the pair of second positioning screw holes 2 is disposed corresponding to the position of the pair of first positioning screw holes 9 according to the bearing 10, two ends of the screw rod 4 are exposed at two sides of the planar base 1, a positioning end cap 5 is coaxially disposed at the rod end on one side of the bottom surface of the planar base 1, a handle 6 is disposed at the other rod end, the positioning end cap 5 is in a cylindrical step structure, the whole external diameter is smaller than the internal diameter of the inner ring of the bearing 10, the big end is fixedly arranged at the rod end of the screw rod 4, the small end protrudes outwards along the axial direction, and the end face of the small end is flat.
