Description

Technical Field

[0001] The utility model relates to the technical field of mine restoration, in particular to an anti-landslide support mechanism for mine restoration. Background Art

[0002] Mine restoration is one of the key points in mountain protection and transformation. Compared with conventional mountain transformation, mines have the characteristics of steep cross-sections and broken terrain due to long-term mining, which can easily cause problems such as soil erosion and landslides.

[0003] In the prior art, the anti-landslide support mechanism used for mine restoration mostly adopts wire mesh laid on the mine surface and baffles set up at the foot of the mountain to prevent the gravel from rolling and falling. The structure is relatively simple. When a landslide causes a large number of rocks to slide down, the wire mesh and baffles can hardly withstand the impact of falling rocks, and have low compression resistance and protection capabilities.

[0004] Therefore, an anti-landslide support mechanism for mine restoration is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-landslide support mechanism for mine repair, comprising: a mine, a reinforced concrete fence is fixedly installed on the surface of the mine, a steel baffle is fixedly installed on the bottom side of the mine surface, a pulling assembly is arranged on one side of the steel baffle, and a supporting assembly is arranged on the other side of the steel baffle.

[0007] As a preferred implementation, a plurality of mounting holes are opened on one side of the mine.

[0008] As a preferred embodiment, a plurality of fixed steel bars are fixedly embedded in the bottom of the reinforced concrete fence, and one end of the plurality of fixed steel bars is fixedly embedded in the surface of the mine.

[0009] As a preferred implementation, a plurality of reinforcing bolts are movably embedded on the surface of the steel baffle, and the bottom ends of the surfaces of the plurality of reinforcing bolts are fixedly embedded in the surface of the mine.

[0010] As a preferred embodiment, the pulling assembly includes a fixed rod and a second steel wire rope, the fixed rod is fixedly embedded in the surface of the mine, the top of the fixed rod is fixedly connected to a first steel wire rope, one end of the first steel wire rope is fixedly connected to a limiting sleeve, one end of the second steel wire rope is fixedly connected to one side of the top of the steel baffle, the other end of the second steel wire rope is fixedly connected to a connecting plate, one side of the connecting plate is fixedly installed with a connecting rod, one end of the connecting rod is fixedly connected to the limiting plate, one side of the limiting plate is fixedly connected to a spring, one end of the spring is fixedly connected to one side inside the limiting sleeve, and the connecting rod, the limiting plate and the spring are all movable inside the limiting sleeve.

[0011] As a preferred embodiment, the support assembly includes a support frame, a limit rod and a plurality of movable top plates, the top of the support frame is fixedly connected to one side of the steel baffle, one side of the support frame is fixedly connected to a steel wire rope, one end of the steel wire rope movably passes through the surface of the limit rod and is connected to a conical top rod, one side of the limit rod is fixedly installed with a mounting ring, one side of the mounting ring is fixedly installed with a plurality of fixed sleeves, the plurality of fixed sleeves are grouped into a group of two, the surface of the limit rod is fixedly embedded in the inside of the mounting hole, and the conical top rod and the movable top plate are movable inside the mounting hole.

[0012] As a preferred embodiment, a movable sleeve is fixedly installed on one side of the plurality of movable top plates, and the plurality of movable sleeves are respectively located in the middle of each group of fixed sleeves, and a limiting movable rod is movably embedded in the middle of each movable sleeve and each group of fixed sleeves, and one end of the conical top rod surface is located in the middle of the plurality of movable top plates.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. The utility model provides a steel baffle, a pulling assembly and a supporting assembly at the foot of a mine to protect and block falling rocks caused by landslides. The steel baffle is fixedly installed on the top of the foot of the mine through the bottom, and is fixed by strengthening bolts. One side is pulled by the pulling assembly to strengthen the impact resistance. When the falling rocks hit the surface of the steel baffle, the connecting plate and the connecting rod will be pulled by the second steel wire rope, and the spring will be pulled synchronously to buffer and reduce pressure, thereby reducing the pulling force on the second steel wire rope and the first steel wire rope to avoid collapse. The other side of the steel baffle is supported by a supporting frame. When the supporting frame receives a large pressure, the steel wire rope and the conical push rod will be pulled, and the conical push rod will move into the movable top plate to squeeze and open the movable top plate. The movable top plate applies pressure through the limiting rod at the top of the conical push rod, and at the same time squeezes the inner wall of the mounting hole to strengthen the fixation, thereby strengthening the supporting capacity of the supporting assembly and simultaneously improving the impact resistance and protection capabilities of the steel baffle.

[0015] 2. The utility model casts a reinforced concrete mesh on the surface of the mine, and a plurality of fixed steel bars are embedded at the bottom of the reinforced concrete mesh. The fixed steel bars are embedded in the mountain on the surface of the mine to strengthen fixation. The reinforced concrete mesh itself has the function of preventing landslides and falling rocks for the mine. At the same time, suitable trees can be planted in the empty grooves inside the reinforced concrete mesh to improve the mountain environment on the surface of the mine. The mountain environment of the mine can be slowly improved over a long period of time through ecological restoration, thereby gradually and fundamentally improving the landslide situation of the mine.
