Description

Technical Field

[0001] The invention relates to the technical field of hydraulic support test equipment, in particular to a hydraulic support simulation test platform. Background Art

[0002] With the improvement of the mechanization degree of coal mining, the large-angle coal seams and steep-angle coal seams have begun to test and gradually popularize comprehensive mechanized coal mining. The fully-mechanized hydraulic support is one of the key equipment of the fully-mechanized coal mining face in coal mines. It controls the roof rock layer of the working area of ​​the working face by interacting with the surrounding rock, and can reliably and effectively support and control the roof of the working face, isolate the goaf, prevent the gangue from entering the mining face, and provide a safe working space for the working face.

[0003] When the equipment is put into production and the hydraulic support is lowered into the mine, it is necessary to arrange the coal mining machine, scraper, and hydraulic support together on the ground to verify the conformity of the three-machine matching relationship in order to avoid bringing problems into the mine. This process not only requires a large investment of manpower, financial resources, and materials, but also the ground cannot simulate the actual operation of the hydraulic support underground. Problems such as the length of the support connection hose involved when the two hydraulic supports move against each other and the reliability of preventing gangue leakage between the supports are also involved.

[0004] Due to the particularity of the geological conditions of large-angle coal seams and steeply inclined coal seams, the various parameters and performances of underground equipment in the inclined state cannot be fully simulated when conducting debugging tests on horizontal ground. Therefore, it is urgent to design a large-angle hydraulic support debugging test platform to verify the various performance parameters of the hydraulic support. Summary of the invention

[0008] Furthermore, four support plate jacks are provided.

[0009] Furthermore, two adjusting plate jacks are provided.

[0010] Furthermore, the base is provided with two groups of hinge holes for hinged connection with the support plate jack, namely an outer hinge hole and an inner hinge hole, and the distance between the outer hinge hole and the hinge axis is greater than the distance between the inner hinge hole and the hinge axis.

[0013] Furthermore, the base is provided with bolt holes for connecting to the ground.

The back of the support plate is hinged to one end of the support plate jack, and the other end of the support plate jack is hinged to the base; the back of the adjustment plate is hinged to one end of the adjustment plate jack, and the other end of the adjustment plate jack is hinged to the base.
