Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will make a detailed description of embodiments of the present invention with reference to the accompanying drawings and examples.
The embodiment provides a tool for detaching a bogie wheel on the inner side of a tracked vehicle, which is structurally shown in figure 1 and comprises a bracket arm 1, a base 2, a connecting bolt 3, a fixing nut 4 and a positioning pin 8.
The middle area of the base 2 protrudes upwards to form a groove structure, and the groove comprises two oppositely arranged guide side walls and a positioning side wall which is connected to the tail ends of the two guide side walls and is vertical to the guide side walls. Wherein, all be equipped with trailing arm mounting hole and locating pin mounting hole on the direction lateral wall, the locating side wall is as the locating surface 9 of trailing arm. At least four crawler connecting holes 5 and 6 are arranged on the edge areas of two sides of the base, and the first crawler connecting hole 5 and the second crawler connecting hole 6 have two different inner diameters and are respectively suitable for connecting two series of mobile system crawlers.
The bracket arm 1 is made of high-strength high-carbon steel materials, and the strength of the bracket arm is improved through heat treatment. The rotating end of the supporting arm 1 comprises a U-shaped supporting surface 7 which is attached to the outline of the root of the balance elbow of the bogie wheel on the inner side of the tracked vehicle. The fixed end of the bracket 1 is arranged in the groove of the base 2, the connecting bolt 3 penetrates through bracket mounting holes in two guide side walls of the groove and a fixed end pin hole of the bracket 1 to connect the bracket 1 with the base 2, the fixing nut 4 is arranged at the threaded end of the connecting bolt 3, and the mounting surface of the fixing bolt 4 is attached to the outer surface of the guide side wall of the groove to lock the connecting bolt 3.
