Description

Technical Field

[0001] This utility model relates to the field of protective equipment, specifically a slope-fixing mesh frame for open-pit coal mines. Background Technology

[0002] An open-pit coal mine refers to a coal seam deposited on the surface or in a shallow layer due to geographical changes, which is mined directly in the open.

[0003] During open-pit coal mining, it is necessary to install anti-slide fixed netting around the perimeter to prevent landslides from damaging surrounding equipment and personnel. However, the existing netting structure is generally a fixed frame combined with a net. The net is used to block landslides, and the net and the fixed frame are fixedly connected. When an impact occurs, the impact force acts directly on the net and is directly transmitted to the fixed frame. Under the action of the impact force, the fixed frame is easily damaged. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0006] Preferably, the fixing mechanism includes a fixing plate and a fixing nail. The fixing plate is fixed around the outer side of the bottom end of the fixing frame, and the fixing nail slides through the fixing plate. In use, the fixing nail cooperates with the fixing plate to fix the fixing frame at the destination position.

[0007] Preferably, the reinforcement mechanism includes a third fixed block, a hollow rod, a movable rod, and a screw. The third fixed block is fixed to the outside of the fixing frame. The hollow rod is hinged between the third fixed blocks. The movable rod is slidably disposed inside the hollow rod. The screw is threaded through one side of the hollow rod. In use, after the fixing frame is installed, the hollow rod is rotated to form an angle between the movable rod and the fixing frame. Then, the movable rod is moved until its lower end enters the soil layer. Afterward, the movable rod is fixed by the screw, so that the movable rod, the hollow rod, and the fixing frame form a triangle, further improving the stability of the fixing frame.

[0008] Preferably, there are four second fixing blocks, with two blocks forming a group, and the gap between the second fixing blocks in each group matches the gap between the first fixing blocks.

[0012] 1. When using this utility model, the first fixing block is placed between the second fixing block, and the adjacent fixing frame can be fixed by passing bolts through, which facilitates the splicing and installation of the fence. When subjected to impact, the impact force is applied to the fence, causing the fence to pull the spring. In this way, the impact force is buffered by the stretching action of the spring, preventing the impact force from acting directly on the fixing frame.

[0013] 2. When using this utility model, after the fixed frame is installed, rotate the hollow rod to make the movable rod and the fixed frame form an angle. Then move the movable rod until the lower end of the movable rod enters the soil layer.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a slope protection mesh frame for open-pit coal mines, including a fixed frame 1 and a barrier net 2. A buffer mechanism is provided between the fixed frame 1 and the barrier net 2. A fixing mechanism is located at the bottom of the fixed frame 1, and a reinforcing mechanism is located on the side of the fixed frame 1. The reinforcing mechanisms are symmetrically installed on both sides of the fixed frame 1. A first fixing block 3 is welded and fixed to one side of the fixed frame 1, and a second fixing block 4 is welded and fixed to the side of an adjacent fixed frame 1. There are four second fixing blocks 4, arranged in pairs. The gap between each pair of second fixing blocks 4 fits with the first fixing block 3. Mounting holes are provided in the centers of both the first fixing block 3 and the second fixing blocks 4. The buffer mechanism includes a first fixing ring 11. The second fixing ring 12 and the spring 13 are used. The first fixing ring 11 is welded and fixed to the outside of the netting 2. The second fixing ring 12 is sleeved on the outside of the first fixing ring 11. The spring 13 is welded and fixed between the second fixing ring 12 and the inner wall of the fixing frame 1. When in use, the first fixing block 3 is placed between the second fixing block 4, and the adjacent fixing frame 1 can be fixed by passing bolts through, which facilitates the splicing and installation of the netting 2. When subjected to impact, the impact force acts on the netting 2, causing the netting 2 to pull the spring 13 to stretch. In this way, the stretching action of the spring 13 buffers the impact force and prevents the impact force from acting directly on the fixing frame 1.

[0021] The fixing mechanism includes a fixing plate 5 and a fixing nail 6. The fixing plate 5 is welded around the outer side of the bottom end of the fixing frame 1. The fixing nail 6 slides through the fixing plate 5. In use, the fixing nail 6 cooperates with the fixing plate 5 to fix the fixing frame 1 at the destination position.

[0022] The reinforcement mechanism includes a third fixing block 7, a hollow rod 8, a movable rod 9, and a screw 10. The third fixing block 7 is welded and fixed to the outside of the fixing frame 1. There are two third fixing blocks 7. The hollow rod 8 is hinged and installed between the third fixing blocks 7. The movable rod 9 slides inside the hollow rod 8. The screw 10 is threaded through one side of the hollow rod 8. When in use, after the fixing frame 1 is installed, the hollow rod 8 is rotated so that the movable rod 8 and the fixing frame 1 form an angle. Then the movable rod 9 is moved until the lower end of the movable rod 9 enters the soil layer. Then the movable rod 9 is fixed by the screw 10, so that the movable rod 9, the hollow rod 8, and the fixing frame 1 form a triangle, which further improves the stability of the fixing frame 1.

[0023] Working principle: When in use, the first fixing block 3 is placed between the second fixing block 4, and the adjacent fixing frame 1 is fixed by bolts passing through, which facilitates the splicing and installation of the netting 2. When subjected to impact, the impact force acts on the netting 2, causing the netting 2 to pull the spring 13 to stretch. In this way, the stretching action of the spring 13 buffers the impact force and prevents the impact force from acting directly on the fixing frame 1. When the fixing frame 1 is installed, the hollow rod 8 is rotated so that the movable rod 8 and the fixing frame 1 form an angle. Then the movable rod 9 is moved until the lower end of the movable rod 9 enters the soil layer. Then the movable rod 9 is fixed by the screw 10, so that the movable rod 9, the hollow rod 8 and the fixing frame 1 form a triangle, which further improves the stability of the fixing frame 1.
