Description

Technical Field

[0001] The utility model relates to the technical field of mine slope supports, in particular to a mine slope support structure. Background Art

[0002] After mining, the mine environment needs to be restored. The rocks on the mine slopes are unstable and prone to rock peeling and falling. Therefore, a support structure is needed to provide auxiliary support for the mine slopes. The existing support structure has a relatively fixed overall structure when in use, which makes it inconvenient to quickly adjust according to the actual use environment and has poor adaptability.

[0003] In response to the above problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent publication number CN218027757U, which is set as a detachable connection through a fixing mechanism and a mounting rod. According to actual needs, the position of the required support can be quickly adjusted, and the mounting plate is fixed to the rock mass through a first pin to ensure that the rubber pad on the mounting plate is in close contact with the rock mass surface. Since the rock mass surface on the mine slope has a large amount of mud and sand, the rubber pad on the mounting plate is in contact with the mud and sand on the rock mass surface. However, after heavy rain, the mud and sand on the rock mass surface are gradually washed away, and the mud and sand in contact with the rubber pad on the rock mass surface will also be washed away. At this time, there is a gap between the rubber pad and the rock mass, which makes it impossible for the mounting plate to fit on the rock mass, and the first pin alone cannot provide the support capacity of the slope rock mass, which will greatly increase the probability of mine slope collapse. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies of the prior art and provide a support structure for a mine slope with a simple structure and strong supporting capacity, so as to solve the technical problem that after heavy rain, there is a gap between the rubber pad and the rock mass in the existing equipment, which makes it impossible for the mounting plate to fit on the rock mass, thereby poorly supporting the mine slope.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A support structure for a mine slope, characterized in that: a column is fixedly installed on the base plate, a rotating groove is provided on the column, a sliding column is rotatably installed in the rotating groove, the sliding column is coaxially connected to two connecting columns, the two connecting columns are detachably connected, a mounting plate is fixed on each connecting column, a rock breaking block is fixed on the end of the mounting plate away from the connecting column, a vertical hole is vertically penetrated in the rock breaking block, a transverse hole is horizontally penetrated in the rock breaking block, and the vertical hole and the transverse hole are connected, a vertical plug block is slidably inserted in the vertical hole, two transverse plug blocks are movably inserted in the transverse hole, and the two transverse plug blocks are abutted against the vertical plug block.

[0007] As a further optimization or improvement of the present solution, a fixing bolt is inserted into the column, and the fixing bolt passes through the rotation groove and is rotationally connected to the sliding column.

[0008] As a further optimization or improvement of the present solution, threaded holes and threaded columns are respectively provided at the ends of the two connecting columns that are close to each other, and the threaded holes and threaded columns are threadedly connected.

[0009] As a further optimization or improvement of the present solution, the upper threaded connection of the mounting plate is provided with two bolt rods.

[0010] As a further optimization or improvement of this solution, hooks are sleeved on the two bolt rods, and the hooks are fixedly connected to the protective net.

[0011] As a further optimization or improvement of this solution, a plurality of limit grooves are provided on the vertical plug block.

[0012] Beneficial effects of the utility model:

[0013] (1) By using tools, the broken rock blocks on the mounting plate are inserted through the mud and sand into the rock mass. When the broken rock blocks are completely inserted into the rock mass, the vertical plug blocks are also smashed downward using tools. When the vertical plug blocks move downward, the inclined surfaces of the vertical plug blocks push the two transverse plug blocks out of the transverse holes, so that the two transverse plug blocks are transversely inserted into the rock mass. At this time, the transverse plug blocks transversely inserted into the rock mass play a role in fixing the rock mass, thereby enhancing the supporting strength of the rock mass of the mine slope, and solving the technical problem that after the supporting equipment in the prior art is washed by heavy rain, the mud and sand contacting the rock mass surface will be washed away, resulting in the inability of the mounting plate to fit on the rock mass, thereby reducing the supporting capacity of the mine slope.

[0014] (2) After the two horizontal plugs are inserted into the rock mass horizontally, the two horizontal plugs will be clamped on the limit grooves on the vertical plugs, and the two horizontal plugs will be limited. At the same time, the vertical plugs are also fixed by the clamping action of the two horizontal plugs, so that the horizontal plugs are horizontally inserted into the rock mass, so that the equipment has a stable supporting capacity, thereby increasing the adaptability of the equipment.

When a part of the installation plate 7 is embedded in the rock mass, the installation plate 7 is stopped. At this time, the rock breaking block 10 has been completely inserted into the rock mass, and then the vertical plug block 9 is hit downward with a tool. During the downward movement of the vertical plug block 9, the vertical plug block 9 is The inclined surface on 9 moves downward accordingly, and the two horizontal plug blocks 11 are separated from the horizontal hole 17. There are two spring sheets inside. The two horizontal plug blocks 11 abutted by the inclined surface of the vertical plug block 9 are pushed out of the horizontal hole 17 along with the downward movement of the vertical plug block 9, and the two horizontal plug blocks 11 are horizontally inserted into the rock body. At this time, the horizontal plug blocks 11 horizontally inserted into the rock body play a role in fixing the rock body, strengthening the supporting strength of the rock body of the mine slope, and solving the technical problem that after the supporting equipment in the prior art is washed by heavy rain, there is a gap between the rubber pad and the rock body, which makes the mounting plate 7 unable to fit on the rock body, thereby reducing the supporting capacity of the mine slope.

However, when the work is completed, the horizontal plug block 11 will be clamped on the limit groove 18 on the vertical plug block 9 to limit the horizontal plug block 11. At the same time, the vertical plug block 9 is also fixed under the clamping action of the two horizontal plug blocks 11, so that the horizontal plug block 11 is always horizontally inserted into the rock mass, and the vertical plug block 9 is also always vertically inserted into the rock mass, so that the equipment has a stable supporting capacity, thereby increasing the adaptability of the equipment.
