Anchorage device sectioning device, sectioning device and sectioning method thereof

Abstract

The invention discloses an anchorage device sectioning device, a sectioning device and a sectioning method thereof. The anchorage device sectioning device comprises a machine body, a bidirectional oil cylinder, a pair of tool bits, a tool setting block, a lever, a spring, a nozzle, a reciprocating pin shaft, a fulcrum pin shaft, a hinge pin shaft, a mechanical arm and an operation table, an anchorage device is clamped to adjust the depth, linear sectioning force exerting is uniform, sectioning is thorough along the diameter, and the bidirectional oil cylinder extends and exert force at the same time, so manpower is saved. The lever rotates to extrude the reciprocating pin shaft, the acting force is amplified by using the force arm difference, and the pair of tool bits are driven to oppositely move to sectioning the anchorage device, so that the force generation strength is high, the spring automatically resets after sectioning is completed, the working efficiency is improved, non-combustible liquid is sprayed in the whole process, gas ignition is avoided, through mechanical arm operation, a worker is away from the sectioning area and is prevented against injury and through the automatic sectioning on an operation table, the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical tools, and in particular relates to a cutting technique. Background technique [0002] After the mining operation is over, the whole cross-drop method is generally used to deal with the goaf roof. In order to prevent secondary accidents caused by large-scale suspended roofs in the gobs of the working face, and excessive pressure at the moment of falling, it is necessary to remove the anchor rods and anchor cables in time to allow the roof to collapse in time. [0003] In the past, when disassembling the anchor nut, if the nut was not rusted, a special pneumatic tool was used with a special sleeve. If the nut is rusted, it is necessary to use a cutter, put it on the nut, pressurize the oil cylinder, and move the moving knife to realize the cutting. Similarly, when dismantling the anchor cable and anchorage, there are certain restrictions on using tensioning tools to withdraw the anchor. If the...

Problems solved by technology

For example, QLAC-15, QLAC-18, QLAC-22, and QLAC-29 anchorage cutters weigh about 18kg, 25kg, 39kg, and 57kg respectively. They are heavy, and manual lifting is laborious, resulting in labor intensity.

Because it is all manual work, there are safety hazards such as bruises, smashes, collapses, etc.

Each operation process is cumbersome, time-consuming, and work efficiency is low
