Mining nut dismounting device and using method

Abstract

The invention discloses a mining nut dismounting device. The mining nut dismounting device comprises a shell, wherein the inner side wall of the shell is connected with a movable shell in a sliding mode; a motor is fixedly installed in the movable shell; a hydraulic telescopic rod is fixedly installed at the bottom end of the movable shell; the other end of the hydraulic telescopic rod is fixedlyconnected with the shell; an output shaft of the motor penetrates through a bearing sleeve; the output shaft of the motor is connected with a torque sensor; a clamping mechanism is mounted on a transmission shaft of the torque sensor; a lubricating mechanism is mounted on the clamping mechanism, at least one handle is mounted on the side surface and the bottom end of the shell; and a controller and a programming controller are further arranged on the side surface of the shell. According to the mining nut dismounting device, automatic lubrication is carried out according to need during disassembling, so that damage is avoided during disassembling and assembling equipment and nuts, torque required by nuts of different specifications is ensured during assembling, the problem of low safety coefficient caused by unreliable installation is effectively avoided, the mining nut dismounting device is suitable for disassembly and assembly operation of nuts of various specifications, and the disassembly and assembly efficiency of machinery is effectively improved.

Description

technical field [0001] The invention relates to the technical field of nut disassembly and assembly, in particular to a mining nut disassembly device and a use method. Background technique [0002] Coal mining machinery belongs to a large classification of machinery. Coal mining machinery is a machine specially used for coal mining. It is different from other mining machinery due to its professional characteristics. As a large country of coal production, China's annual coal output is constantly increasing. The production of machinery plays a pivotal role in our country. Since coal mining machinery needs a long time to move its position, corresponding disassembly devices are needed for disassembly auxiliary operations. [0003] With the wide application of coal mining machinery, the coal mining machinery needs to be disassembled repeatedly due to its short service life in a fixed working place, and it is necessary to ensure that the device is disassembled without damaging the...
