Embodiment Construction

[0012] like figure 1 Shown is a schematic structural diagram of a portable filling, mining and tamping simulation device of the present invention. The device is mainly composed of a box body 1, a rotating handle 2, a rotating threaded rod 3, a separate hydraulic jack, an oil delivery hose 4, and a spherical joint 5. , hinged joint support 6, side limit plate 7; box body 1 is welded by steel plate with a thickness of 1cm, and the top cover is fixedly connected with bolts, which is convenient for dismantling the top cover, which is convenient for the objects inside the box body 1. Maintenance repairs. Convenient disassembly In order to make the box body 1 provide sufficient support without deformation, the rear plate of the box body 1 is welded with a steel plate with a thickness of 2 cm, and the outer surface of the entire box body 1 is sprayed with a layer of blue paint. A round hole is left on the upper part of the box body 1, and the quick connector 8 on the oil delivery ho...

Abstract

The invention belongs to the technical field of coal gangue filling mining, and particularly relates to a portable filling mining tamping simulating device. The device structure principle and experiment actions meet the requirement of tamping mechanism laboratory simulation experiments of gangue filling supports. The whole operation process and the implementing filling tamping process of the device have the high similarity, material tamping rules in the actual filling process can be mastered in a laboratory through simulation experiments, a large amount of manpower, material resources, financeforce and time cost for industrial experiments can be saved, the uncertain risk for the industrial experiment results is reduced, and the economical applicable effect is remarkable. The device is easy to carry, related parameter design can be changed, and the requirement for different occasions can be met.

Description

technical field [0001] The invention belongs to the technical field of coal gangue filling and mining, in particular to a portable filling and mining tamping simulation device. Background technique [0002] In the process of coal gangue filling and mining, the filling support is an indispensable equipment, which plays an important role in the transportation, filling and compaction of coal gangue. The compaction mechanism of the gangue-filled support is responsible for the filling and compaction of coal gangue in the goaf, which is a distinctive feature that is different from other supports. After the gangue is filled into the goaf, the tamping mechanism pushes and tampers it, and increases the density of the loose gangue on the basis of pushing and ramming and roofing, so as to improve the compressive capacity of the filled gangue, so that it can withstand a certain roof subsidence. pressure and reduce the subsidence of the roof, thereby effectively controlling the surface ...
