Hinge pin and stable nail pin extractor

Abstract

A hinge pin and stable nail pin extractor is simple in structure and convenient in use and comprises a handle. A stop circle is fixedly connected to one side of the handle, a slide bar is fixedly connected to the other side of the stop circle, the slide bar, the stop circle and the handle are structurally integrated, the diameter of the section of the slide bar is smaller than that of the section of the stop circle, a threaded connecting groove is disposed at the other end of the slide bar and is open outwards, and internal threads are disposed in the threaded connecting groove. A connecting rod is fixedly connected to the other end of the slide bar, and the threaded connecting groove is disposed at the other end of the connecting rod. A hanging pin is connected with the internal threads of the threaded connecting groove and consists of a pin extracting portion and a connecting portion, both the pin extracting portion and the connecting portion are provided with external threads, and the connecting portion is connected with the threaded connecting groove. A sliding hammer gyroscope is penetratingly disposed on the slide bar, is in the shape of a circular tube and is slidably connected with the slide bar left and right. The hinge pin and stable nail pin extractor has the advantages that work intensity of constructors can be reduced when the constructors repair speed reducers, work efficiency is improved, the hinge pin and stable nail pin extractor is light, is easy to be carried and brings convenience for disassembly, and operation can be completed by one person.

Description

[0001] technical field [0002] The invention relates to mining equipment, in particular to a pin shaft and a stabilizing pin extractor. Background technique [0003] In industrial machinery production equipment, the reducer is the most common type. It is responsible for the important link in the operation of the equipment. Generally, the more commonly used reducers include cylindrical gear reducers and planetary gear reducers. Their appearance is relatively heavy. The internal structure is relatively simple, mainly relying on the meshing of internal gears. The gears are generally inseparable from the overhead shaft during the inlay process. It is difficult to take out the pin shaft during maintenance. There is no special tool for reducer maintenance on the market. The conventional removal method is Two people use a sledgehammer to beat, which is cumbersome and laborious to work, and sometimes it will be skewed, causing damage to other accessories.
