Abstract

The invention discloses a hinge pin disassembling device for fully-mechanized coal mining and excavating equipment. The hinge pin disassembling device comprises a lower pulling disc and an upper supporting disc, wherein a lining is arranged outside the lower pulling disc in a sleeving manner, the upper supporting disc is arranged at the end part of the lining, a hydraulic jack is arranged at the side, far from the lower pulling disc, of the upper supporting disc, an ejector rod of the hydraulic jack drives the lower pulling disc to move in the lining along the axis, and the lower pulling disc is connected with a hinge pin of a disassembled workpiece. The invention further discloses a using method of the hinge pin disassembling device for the fully-mechanized coal mining and excavating equipment. The hinge pin disassembling device for the fully-mechanized coal mining and excavating equipment is simple in structure, convenient to operate, firm in connection, high in reliability and large in disassembling force. The maximum pulling force can reach near 300KN, the workpiece and a structural component are pressed as a whole, deformation and even damage which are caused by uneven force application are avoided, the working efficiency is increased, and the labor intensity is reduced.

Description

Technical field [0001] The invention belongs to the field of coal mining. More specifically, the invention relates to a pin detacher for fully mechanized mining equipment and its use method. Background technique [0002] In the process of coal mining, with the improvement of mine mechanization, the installation and dismantling of fully mechanized mining and fully mechanized excavating equipment are more frequent. The installation and dismantling of fully mechanized mining and fully mechanized excavating equipment are all realized through the installation and removal of pins. In the harsh environment of the underground, the pin of the equipment used is deformed due to large force or rusted due to high humidity, which makes it difficult to disassemble the pin; there are special environmental conditions such as combustible gas in the coal mine, so heating and baking cannot be used. In the prior art, the destructive dismantling is done by using the shovel cylinder, the rear support c...
