Stimulated comprehensive experimental device for anchorage construction of anchor bolt support

Abstract

The invention relates to a stimulated comprehensive experimental device for anchorage construction of an anchor bolt support, which can effectively solve the problem of stimulation of a mine roadway support to ensure the stimulation quality and the mine safety production. The stimulated comprehensive experimental device adopts the structure that a bracket table comprises an square upper box and supporting legs mounted on a middle plate at four corner of the lower part of the square upper box; lower intermediate plates placed on the ground are installed at the lower end parts of the supporting legs; angle steels are installed on the corresponding two sides of the square upper box; an artificial ladder placed on the ground is arranged on one side of the upper part of the bracket table; an artificial handrail is arranged at the upper part of the bracket table; a portal framework is fixedly installed on the angle steels through bolts; an oil cylinder is installed at the upper part of the portal framework to from a pressing device; and a model box composed of a box body, a baffle and a pressing plate playing a compacting role is placed inside the portal framework. The stimulated comprehensive experimental device has the advantages that an anchor bolt can be drilled towards the inside of a platform through an anchor bolt machine below the experimental platform, the anchorage process of the roadway anchor bolt support is stimulated, the information of the anchor bolt machine in the drilling process is detected, and the construction and the effect monitoring of the roadway anchor bolt can be facilitated.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a bolt support and anchorage construction simulation comprehensive experiment device. Background technique [0002] The simulation experiment method of similar materials has always been the main experimental method in the experimental research of mining engineering. Its essence is to use materials with similar mechanical properties to the model on the test bench to shrink the experimental model according to a certain ratio of geometric similarity. The model can be excavated into various projects, such as mine roadways, chambers, and longwall stopes. Through the simulation and experimental observation of the engineering process, the mechanical phenomena such as deformation, movement, and destruction of the surrounding rock mass of the project can be studied, and Analyze the forces acting on the supporting structure. The traditional similar material simulation experiment method of...

Problems solved by technology

The traditional similar material simulation experiment method of roadway bolt support effect generally uses a plane simulation experiment device, which can only study a section of the prototype, and for the research object with changes in three-dimensional stress, the plane simulation experiment platform is unreasonable. sex

The plane test bench cannot simulate the process of bolting in the roadway to obtain the force of the bolt and the quality inspection of the support; its clamping structure is also unreasonable. After long-term experiments, the channel steel will cause differences. The degree of bending, the uneven surface of the model after installation, affects the similarity of the model; the lifting of the model frame is inconvenient, and the lifting process is not easy to control. Often, vibrations are generated due to improper speed control after molding, which damages the internal structure of the model, resulting in inaccurate experimental structures. Affect the safety prevention of mine roadway support and cause safety accidents
