Description

Technical Field

[0001] This utility model relates to the field of anti-slope protection netting technology, specifically an anti-slope protection netting device for mine restoration. Background Technology

[0002] The anti-slope protection netting device for mine restoration is mainly used to prevent geological disasters such as landslides, collapses and rockfalls, and to ensure the safety of mining projects. It intercepts rock and soil and falling rocks to prevent them from sliding into the mining operation area or affecting surrounding facilities.

[0003] Chinese patent CN222541383U proposes an anti-slide protective barrier net, including a barrier net body, a fixing strap, and positioning components. The barrier net body is disposed in the inner cavity of the fixing strap. Positioning components are symmetrically fixed on both sides of the barrier net body. Limiting components are installed on the positioning components. By utilizing the cooperation between the various structures in this component, the device can quickly and stably replace the damaged barrier net body when it is damaged. This solves the problem that existing devices require three steps for replacement: pulling out, replacing, and re-installing in the river embankment. The process of pulling out the fixing anchor bolts is very time-consuming and laborious, resulting in low efficiency when replacing damaged protective barriers.

[0004] The anti-slide guardrail device in the above scheme does not have a winding structure, which makes it difficult for the device to adjust the tightness of the anti-slide guardrail according to the slope change. As a result, it will affect the degree of fit between the anti-slide guardrail and the slope surface, thus adversely affecting the anti-slide effect. In addition, it is also extremely inconvenient to wind up and transport the anti-slide guardrail. Utility Model Content

[0005] The purpose of this utility model is to provide a landslide prevention fence device for mine restoration, so as to solve the problem mentioned in the background art that the device is difficult to adjust the tightness of the landslide prevention fence according to the slope change, which will affect the degree of fit between the landslide prevention fence and the slope surface, and thus have an adverse effect on the landslide prevention effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a landslide protection fence device for mine restoration, comprising a fixed frame, a winding rod rotatably connected inside the fixed frame, movable seats symmetrically fixedly installed at both ends of the winding rod, a rotating handwheel fixedly installed on one side of each of the two movable seats, and the landslide protection fence body movably wound up at the outer end of the winding rod.

[0007] The bottom of the fixed frame is symmetrically fixed with mounting plates, and an air blowing head is fixedly installed between the two mounting plates. A filter screen is fixedly installed at the bottom of the air blowing head, and a transmission pipe is fixedly installed at the top of the air blowing head.

[0008] Preferably, a counterweight is fixedly installed at one end of the anti-slip slope guardrail body, and a disassembly component is provided at the outer end of the counterweight. Multiple fixing plates are fixedly installed on one side of both the disassembly component and the counterweight, and a ground pin is connected through the interior of each fixing plate.

[0009] Preferably, the disassembly assembly includes a through hole, which is formed inside the counterweight rod. A connecting shaft is connected through the through hole, and a C-shaped fixing seat is rotatably connected to the outer end of the connecting shaft.

[0010] Preferably, the two ends of the connecting shaft are symmetrically provided with bolt threads, and the outer ends of the two bolt threads are threaded with fixing nuts.

[0011] Preferably, both movable seats are rotatably connected to the inner wall of the fixed frame, and the rotating handwheel is located on both sides of the fixed frame.

[0012] Preferably, the transmission pipe is fixedly connected to the output end of the booster pump, and the air blowing head is located above the anti-slip slope guardrail body.

[0013] Preferably, the two fixing nuts are located on both sides of the C-shaped fixing seat, and the connecting shaft passes through the interior of the C-shaped fixing seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a winding rod, movable seat, rotating handwheel and anti-slip slope guardrail body, rotating the handwheel causes the movable seat to rotate, and the two movable seats drive the winding rod to rotate synchronously. The winding rod is used to wind up the anti-slip slope guardrail body. In this way, it is convenient to store and transport the anti-slip slope guardrail body, and it is also convenient to adjust the tightness of the anti-slip slope guardrail device so that it can fit tightly to the slope surface and avoid the guardrail from loosening or falling off due to changes in slope.

[0016] 2. By setting up an installation plate, air blower, filter screen, and transmission pipe, the booster pump can deliver gas from the transmission pipe to the air blower. The air blower cleans the anti-slip fence body, making it easier to remove impurities and dust attached to the surface of the anti-slip fence body, and making the winding of the anti-slip fence body cleaner.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5This utility model provides a technical solution: a landslide prevention fence device for mine restoration, including a fixed frame 1. A winding rod 21 is rotatably connected inside the fixed frame 1. Movable seats 22 are symmetrically fixedly installed at both ends of the winding rod 21. A rotating handwheel 23 is fixedly installed on one side of each of the two movable seats 22. The landslide prevention fence body 24 is movably wound up at the outer end of the winding rod 21. Mounting plates 31 are symmetrically fixedly installed at the bottom of the fixed frame 1. An air blowing head 32 is fixedly installed between the two mounting plates 31. A filter screen 33 is fixedly installed at the bottom of the air blowing head 32. The filter screen 33 prevents dust from entering the pipe and facilitates... The internal structure of the cleaning unit is protected. A transmission pipe 34 is fixedly installed on the top of the air blowing head 32. Both movable seats 22 are rotatably connected to the inner wall of the fixed frame 1. The rotating handwheel 23 is located on both sides of the fixed frame 1. The transmission pipe 34 is fixedly connected to the output end of the booster pump. The air blowing head 32 is located above the anti-slip slope guardrail body 24. This structure can roll up the anti-slip slope guardrail body 24, which is convenient for the transportation and storage of the anti-slip slope guardrail body 24. At the same time, it is also conducive to adjusting the tightness of the anti-slip slope guardrail body 24, thereby improving the anti-slip effect on the mine slope and more effectively ensuring the safety of workers.

[0025] Please see Figure 1 , Figure 2 and Figure 3 One end of the anti-slip slope guardrail body 24 is fixedly installed with a counterweight 4. A disassembly assembly is provided at the outer end of the counterweight 4. Multiple fixing plates 6 are fixedly installed on one side of both the disassembly assembly and the counterweight 4. A ground pin 7 is connected through the interior of each fixing plate 6. The disassembly assembly includes a through hole 51, which is located inside the counterweight 4. A connecting shaft 52 is connected through the through hole 51. A C-shaped fixing seat 53 is rotatably connected to the outer end of the connecting shaft 52. Bolt threads 54 are symmetrically provided at both ends of the connecting shaft 52. The outer ends of the bolt threads 54 are all threaded with fixing nuts 55. The fixing nuts 55 and bolt threads 54 cooperate to limit the C-shaped fixing seat 53. The two fixing nuts 55 are located on both sides of the C-shaped fixing seat 53. The connecting shaft 52 passes through the interior of the C-shaped fixing seat 53. This structure facilitates the disassembly of the bottom fixing structure of the anti-slide fence body 24, thereby facilitating the storage of the anti-slide fence body 24 and preventing the bottom fixing structure of the anti-slide fence body 24 from being caught on the slope during storage.

[0026] Working principle: The workers place the anti-slide fence body 24 on the mine slope and use the ground pin 7 to fix the anti-slide fence body 24 to the slope surface. When it is necessary to adjust the tightness of the anti-slide fence body 24, turn the rotating handwheel 23. The rotating handwheel 23 will roll up the anti-slide fence body 24, thereby adjusting the fit between the anti-slide fence body 24 and the slope surface. When the equipment is not in use, turn the fixing nut 55 to remove it from the bolt thread 54 surface, pull out the connecting shaft 52, and separate the C-type fixing seat 53 from the counterweight 4. Next, rotate the handwheel 23. Rotating the handwheel 23 drives the movable seat 22 to rotate, and the movable seat 22 drives the winding roller 21 to rotate. The winding roller 21 winds up the anti-slip slope guardrail body 24. During the winding process, if impurities are attached to the surface of the anti-slip slope guardrail body 24, start the booster pump. The booster pump delivers gas to the air blowing head 32 through the transmission pipe 34. The air blowing head 32 blows air to clean the surface of the anti-slip slope guardrail body 24 before winding. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
