Description

technical field [0001] The invention relates to a mining mechanical equipment, in particular to a hydraulic shaft disconnector. Background technique [0002] In the long-term production practice, due to the long operating period of the equipment, the pins and shafts of the mechanical structure of the equipment are often damaged. At present, it is necessary to use a manual lever hammer to disassemble. The method is difficult to disassemble and assemble when replacing on-site underground. It takes a long time, and at the same time, it is easy to damage the equipment, so that it affects production. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic shaft disconnector with simple structure and convenient use. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a hydraulic shaft release device, including a screw rod, which is characterized in that: the right part of the screw ...
