Intelligent loading multi-dimensional similar model test device

Abstract

The invention discloses an intelligent loading multi-dimensional similar model test device. A vertical model frame comprises a base and four stand columns vertically fixed to the four corners of the base respectively; a front-back baffle plate group and a left-right baffle plate group are detachably connected among the four stand columns, and a plurality of groups of square tube groups penetrate through the lower part of the front-back baffle plate group; a top oil pressure loading mechanism can apply pressure from top to bottom to the interior of a loading simulation area; a bottom oil pressure loading mechanism can apply pressure from bottom to top to the interior of the loading simulation area; a hydraulic system is used for realizing loading control on the top oil pressure loading mechanism and the bottom oil pressure loading mechanism; and a water bag loading mechanism comprises one or more water bags arranged in the loading simulation area and a pressure control assembly located outside the loading simulation area and connected with the water bags. The test device is simple in structure, reasonable in design and easy and convenient to use and operate. With the test device adopted, the problems of difficulty in reconstructing a l a three-dimensional space, low automation degree, and difficulty in obtaining key information in an existing model can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of similar physical simulation tests, in particular to an intelligent loading multi-dimensional similar model test device. Background technique [0002] my country's coal resources are relatively rich, but the conditions of occurrence are relatively complex, and mining is difficult. At present, the basic research on deep coal mining is relatively weak, which makes the coal industry pay a relatively high price while meeting the needs of energy development. Among them, accurate detection of deformation and damage of mining surrounding rock is the basis for disaster control technologies such as scientific mining, rock formation control, water conservation coal mining, and surface ecological restoration. Many scholars at home and abroad have conducted a lot of in-depth research on the key scientific issues of the deformation and failure mechanism and evolution law of the surrounding rock in the stope. Among th...

Problems solved by technology

At the same time, due to the limited size of the model frame, it is often impossible to simulate the entire formation, and it is necessary to apply pressure on the top to achieve the stress condition. At present, most of them use the form of counterweights for manual stacking, which is time-consuming, laborious and has operational risks.
