Description

Technical Field

[0001] The invention relates to the technical field of super-large tonnage hydraulic support test benches, and in particular to a super-large tonnage hydraulic support test bench test piece loading and unloading device and method. Background Art

[0002] my country's coal resources have generally entered the deep mining stage. The high stress and strong disturbance in the deep cause the damage of dynamic disasters such as rock burst to become more severe. In severe cases, it will cause the tunnel of several hundred meters to shrink and deform instantly, collapse and damage the support body. In response to this engineering problem, the development of support equipment with anti-impact and anti-impact characteristics is urgently needed in the deep mining stage of mines with dynamic disasters such as rock burst.

[0003] Hydraulic support is a key support equipment in the process of coal mining. The roof of the fully-mechanized mining face acts directly on the top beam of the hydraulic support in the form of external load. The hydraulic support needs to provide safe and reliable support for the roof of the working face to prevent the rocks that fall due to the broken roof from falling into the supporting working face, and play the role of isolating the goaf. When working, it is used in conjunction with the coal mining machine, and can realize a whole set of processes such as lifting, pushing, lowering and moving, which improves the production efficiency of the coal mining machine, reduces the workload of workers, and ensures the safety of workers' lives to the greatest extent. However, the underground geographical environment of coal mines is complex and the working conditions are quite harsh. In order to meet energy needs, various countries have improved and innovated hydraulic support equipment, resulting in a corresponding increase in the height, volume and tonnage of the support. With the increase in the length of the fully-mechanized mining face of coal mines and the intensification of coal wall slabs, the load on the support during work has been increased, resulting in damage to key components. Therefore, in the current situation where the call for coal mine safety is getting higher and higher, the production quality of hydraulic supports is particularly important.

[0004] At present, the loading and unloading of hydraulic supports on the hydraulic support test bench is still in the manual assistance mode. When the support is transported to the loading position of the test bench, it is necessary to manually control the direction of the loading posture of the hydraulic support on site. The slight adjustment of the left and right and front and back positions of the support requires manual adjustment. In addition, when the hydraulic support needs to be lifted, manual intervention is also required on site. The center of gravity of the support placed on the forklift and other transportation mechanisms is unstable, causing the support to tilt or even fall, avoiding safety accidents. Therefore, there are too many manual behaviors in adjusting the loading posture of the hydraulic support, which not only causes a waste of human resources, but also poses potential risks.
