Example Embodiment

[0011] When in use, the worm gear drive mechanism is fixed to the back of the female socket through the screw fixing hole 1 at the bottom of the open circular ring 9, and the two copper head fixing plates are fixed to the back of the copper socket through the screw fixing hole 1 on the top. At the same time, the drive hole rectangular plate 3 on the top of the two inner semicircular rectangular plates 5 of the sub copper head fixing plate 4 clamps the worm 7, and the worm 7 is moved forward and backward through the forward and reverse rotating turntable 6, and the worm 7 passes through the drive hole 2. Drive the copper head to pull out.

[0012] The turbine 8 and the worm 7 and the turbine shaft 11 of the worm gear transmission mechanism are engraved by the steel pipe of the machine tool, the worm 7 and the turbine shaft 11 are welded and connected, the turbine shell 12 is cast by a mold, and the top of the turbine shaft 11 is welded with a turntable 6 and the sub copper head is ...

Abstract

The invention discloses a copper head pulling-out device for a coal mine, relates to a coal mine underground switch copper head pulling-out tool, and belongs to the field of mining machines. The copper head pulling-out device is overall composed of subsidiary copper head fixing plates and a worm wheel and worm transmission mechanism. Each subsidiary copper head fixing plate is composed of two semicircular rectangular plates with the semicircular inner sides. Semicircular transmission holes with threaded holes are formed in the top and the bottom of each subsidiary copper head fixing plate. Semicircular screw fixing holes are formed in the upper side and the lower side of each transmission hole rectangular plate. In use, a subsidiary copper head can be pulled out of a master copper head stably, in the whole process, power output is stable, vibration is not generated, and the subsidiary copper head and the master copper head are not damaged; meanwhile, the manual forced dragging processis also omitted, and thus the labor intensity of workers is greatly lowered; and the copper head pulling-out device is easy to manufacture and mount and convenient to use, and extremely has the popularization value.

Description

technical field [0001] The invention relates to a tool for extracting a copper head of an underground switch in a coal mine, which belongs to the field of mining machinery. Background technique [0002] In the coal mine, when installing the switch, it is necessary to insert the sub-copper head with the cable into the female copper head of the switch. During maintenance, the sub-copper head needs to be pulled out from the female copper head of the switch. This process, Normally, the sub-copper head at the interface is loosened by shaking the cable, and at the same time, the steel pipe is used to hit the sub-copper head in reverse. Loose, so it is urgent to develop new tools. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, to provide a kind of copper head extraction device for coal mines that can be fast, safe, efficient, and does not damage the mother and child copper heads. [0004]...
