Material compacting device for similar material simulation test and using method

Abstract

The invention relates to a material compacting device for a similar material simulation test and a using method. The material compacting device is particularly suitable for a similar material simulation test in the fields of mining engineering and geotechnical engineering. The device consists of a pressurizing plate, a dual-acting hydraulic jack, a dual-acting hydraulic jack base, a hand-operated spiral lift and a hand-operated spiral lift base. The hand-operated spiral lift is controlled to enable the pressurizing plate and the dual-acting hydraulic jack to descend to a suitable position above a testing material, the dual-acting hydraulic jack is controlled to enable a piston of the dual-acting hydraulic jack to vertically move repeatedly, and the pressurizing plate is driven to repeatedly compact the test material. The material compacting device is high in resetting speed and large in pressure, can meet requirements on repeated pressurizing to the test material, and is good in material compacting effect; the compacting range is large, the compacting speed is high, the labor intensity is reduced, and the test efficiency is improved; and the material compacting device is simple in structure, convenient to implement, high in maneuverability, convenient to control and low in manufacturing and repairing cost.

Description

technical field [0001] The invention relates to a material compacting device and a use method for similar material simulation tests, and is especially suitable for similar material simulation tests in the fields of mining engineering and geotechnical engineering. Background technique [0002] The similar material simulation test is to use artificial materials with similar physical and mechanical properties to natural rock (soil), according to the actual prototype of geological conditions such as mines, scientifically follow a certain proportion to make a model, and then carry out roadway excavation and coal mining in the model Working face mining, etc. to simulate stope activities, observe the movement, deformation and destruction of rock formations, and speculate on what happened in the on-site prototype. Due to its clear and intuitive effects, similar material simulation tests play an important role in the research of scientific issues in the fields of mining engineering a...

But this type of device increases the number of jacks, complex structure, high manufacturing cost and maintenance cost; although the compaction device has realized automation, the compaction range is limited, in order to compact all materials need reciprocating motion, making the compacted material The time is greatly extended, it is difficult to meet the requirements of rapid compaction of materials, and the efficiency is low; and because the device needs to move continuously to compact the materials like manual methods during the working process, the compactness and flatness of the materials cannot be guaranteed

(2) The existing patent CN103728422B discloses a self-moving cloth and vibration device for similar simulation tests. Although the vibration of the test material can be realized, the vibration range of the device is limited, and it needs to be moved continuously like the manual method The efficiency of vibrating the material is low; the device is an independent device, its structure is too complicated, the manufacturing cost and maintenance cost are too high, and it is prone to failure; Although the material device and its use method can also realize the compaction of the test material, the compaction range of the device is limited, and it still needs to be moved continuously to compact the material like the manual method, and the efficiency is low; the device is also an independent device. Moreover, devices such as hydraulic cylinders (jacks) are added, the structure is complicated, and the manufacturing cost and maintenance cost are high
