[0027] As Figures 1-3 shown, this application provides an anti-landslide fixed grid for open-pit coal mines, including a first fixed column 1 and a second fixed column 2. The bottoms of the first fixed column 1 and the second fixed column 2 are both fixedly connected with support plates 3. A plurality of mounting holes are symmetrically arranged on the support plates 3, and expansion bolts 4 are arranged in the mounting holes. A plurality of protection components 5 are arranged at equal intervals on the first fixed column 1 and the second fixed column 2. A fixed grid 6 is arranged between the first fixed column 1 and the second fixed column 2, and the fixed grid 6 is located inside a plurality of protection components 5. When the first fixed column 1 and the second fixed column 2 are fixed, first pour a concrete foundation at the required use position, and then fix the support plates 3 on the concrete foundation through the expansion bolts 4 to fix the first fixed column 1 and the second fixed column 2. The utility model surrounds the fixed grid 6 with a plurality of protection components 5 to form an effective protection barrier. When encountering unexpected situations such as falling rocks and ore truck collisions, the protection components 5 can bear the impact force first, protect the fixed grid 6 from being directly damaged, thereby extending the service life of the fixed grid 6 and ensuring the protection effect of the fixed grid 6.
[0028] AsFigures 1-3 As shown in the figure, the protection component 5 includes a protection rod 51, a first spring 52, a second spring 53 and a protection plate 54. The protection rod 51 is U-shaped. One end of the protection rod 51 movably penetrates through the first fixed column 1, and the other end of the protection rod 51 movably penetrates through the second fixed column 2. A first limiting member 511 and a second limiting member 512 are fixedly provided on the protection rod 51. The first spring 52 and the second spring 53 are both sleeved on the protection rod 51. The first spring 52 is located between the first limiting member 511 and the first fixed column 1. One end of the first spring 52 is connected to the first limiting member 511, and the other end of the first spring 52 is connected to the first fixed column 1. The second spring 53 is located between the second limiting member 512 and the second fixed column 2. One end of the second spring 53 is connected to the second limiting member 512, and the other end of the second spring 53 is connected to the first fixed column 1. The protection plate 54 is detachably connected to the protection rod 51. When the protection plate 54 is damaged or worn during long-term use, it can be conveniently replaced without replacing the entire protection component 5, reducing the maintenance cost and workload. During actual use, the protection rod 51 is placed on the slope side, and the protection plate 54 is placed on the far slope side. Through a plurality of spaced protection rods 51, larger falling rocks can be blocked, while smaller falling rocks will be intercepted by the fixed wire mesh 6, reducing the impact on the fixed wire mesh 6. When the mine car collides with the protection plate 54 or the falling rock impacts the protection rod 51, the first spring 52 and the second spring 53 play a buffering role, dispersing and weakening most of the impact force, thereby reducing the force transmitted to the fixed wire mesh 6 and effectively protecting the fixed wire mesh 6 from being directly damaged.
[0029] As Figure 2 shown in the figure, a first connecting member 513 is fixedly provided at one end of the protection rod 51, and a second connecting member 514 is fixedly provided at the other end of the protection rod 51. Plug-in slots 7 are provided on both the first connecting member 513 and the second connecting member 514. The protection plate 54 is inserted into the first connecting member 513 and the second connecting member 514 through the plug-in slots 7. The installation process is simple and fast, without the need for complex tools and cumbersome operation procedures. This greatly improves the installation efficiency and saves labor and time costs. When the protection plate 54 needs to be replaced, the protection plate 54 can be easily pulled out from the plug-in slot 7 for quick replacement, making the maintenance and repair work more convenient.
[0030] As Figure 1 and Figure 3 shown in the figure, a warning sign 8 is attached to the side of the protection plate 54 away from the fixed wire mesh 6. The warning sign 8 can attract the attention of the staff and remind the mine car operators of the existence of the protection plate 54. In working environments such as open-pit coal mines, where the operators and mine cars are active frequently, the warning sign 8 can, to a certain extent, prevent accidental collisions with the protection plate 54 due to negligence, reduce the occurrence of accidents, and improve the safety of the workplace.
[0031] AsFigures 1-3 As shown in the figure, a plurality of connecting rods 61 are provided on both sides of the fixed grid 6. Support members 9 corresponding to the connecting rods 61 are provided on the first fixed column 1 and the second fixed column 2. Connecting grooves 91 adapted to the connecting rods 61 are provided on the support members 9. The connecting rods 61 are placed in the corresponding connecting grooves 91, making the installation process simple and fast. Just placing the connecting rods 61 in the connecting grooves 91 at the corresponding positions can complete the connection of the fixed grid 6 with the first fixed column 1 and the second fixed column 2, without the need to use complex tools and cumbersome installation steps, greatly improving the installation efficiency. When it is necessary to disassemble the fixed grid 6, applying an upward force to the fixed grid 6 can separate the connecting rods 61 from the connecting grooves 91, which is convenient for maintenance and replacement.
[0032] As Figure 1 and Figure 3 shown, first reinforcing plates 10 are provided between the first fixed column 1 and the corresponding support member 9, and between the second fixed column 2 and the corresponding support member 9. The setting of the first reinforcing plates 10 increases the connection strength between the first fixed column 1, the second fixed column 2 and the corresponding support member 9.
[0033] As Figure 1 and Figure 3 shown, second reinforcing plates 11 are provided between the first fixed column 1 and the corresponding support plate 3, and between the second fixed column 2 and the corresponding support plate 3. The setting of the second reinforcing plates 11 increases the connection strength between the first fixed column 1, the second fixed column 2 and the corresponding support plate 3.
[0034] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
