Description

Technical Field

[0001] This utility model relates to a support and reinforcement device for mining tunnels, belonging to the field of support and reinforcement technology. Background Technology

[0002] Mining is a science and technology that extracts mineral resources from the Earth's crust or surface. The mining industry is an important raw material industry. Mining is divided into two types: underground mining and surface mining. Underground mining is very dangerous and prone to collapse. Underground mining requires the use of support and reinforcement devices to support and reinforce the mine shafts, reduce the occurrence of collapses, and ensure the safety of workers.

[0003] Existing support and reinforcement devices typically require multiple sets of support frames for actual use. To ensure the support effect, support plates need to be installed between adjacent sets of support frames to support the top. Existing support plates are mostly fixed between adjacent sets of support frames with bolts, which cannot be adjusted and are relatively inconvenient to install.

[0004] Therefore, this utility model proposes a new solution. Utility Model Content

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-6 As shown, the support and reinforcement device for mine tunnels provided in this embodiment includes several sets of support frames. Each set of support frames includes two columns 1, and a top frame 2 is installed on the top between the two columns 1. A connecting mechanism is provided between adjacent sets of support frames. The connecting mechanism includes a first screw 3 fixedly connected to the middle of the front and rear sides of the top frame 2, and a first internal threaded pipe 4 that cooperates with the first screw 3. The connecting mechanism also includes two symmetrically arranged support plates 5. The top surface of the support plate 5 is flush with the top surface of the top frame 2. One end of the support plate 5 is rotatably installed on one of the support frames, and the other end of the support plate 5 is movably installed on the other support frame. By setting up the connecting mechanism, and by setting up two sets of symmetrical support plates 5, with the top surface of the support plate 5 flush with the top surface of the top frame 2, a supporting function is achieved. One end of the support plate 5 is rotatably installed on one of the support frames, and the other end of the support plate 5 is movably installed on the other support frame, so the distance between adjacent sets of support frames can be adjusted to a certain extent. By setting up the first internal threaded pipe 4 and the first screw 3, rotating the first internal threaded pipe 4 to cooperate with the first screw 3 facilitates the adjustment of the distance between adjacent sets of support frames.

[0027] In this embodiment, as Figure 1 , Figure 4 and Figure 5As shown, rotating blocks 6 are fixedly connected to both the front and rear ends of the support plate 5. Sliding holes 7 are provided at both the upper and lower ends of the rotating blocks 6. A protruding rod 8 is slidably installed on the inner side of the sliding hole 7. A spring 9 is installed at the bottom of the protruding rod 8. A limiting groove 10 is provided on the outer wall of the sliding hole 7. A limiting block 11 that slides with the limiting groove 10 is connected to the outer wall of the protruding rod 8. Bosses are provided on the upper and lower surfaces of both the front and rear sides of the top frame 2. Two first rotating holes 12 are provided on the boss located on the front side. The first rotating holes 12 are rotatably connected to the protruding rod 8. Two sliding grooves 13 are provided on the boss located on the rear side. The sliding grooves 13 are movably connected to the protruding rod 8. By setting the sliding hole 7, the protruding rod 8 and the spring 9, the support plate 5 is installed. The protruding rod 8 is squeezed to compress the spring 9, so that the rotating block 6 is placed between the upper and lower bosses. The protruding rods 8 at both ends of the support plate 5 enter the first rotating hole 12 and the sliding groove 13 respectively, thereby quickly installing the support plate 5. Due to the setting of the sliding groove 13, one end of the support plate 5 can slide in the sliding groove 13, thereby adjusting the distance between two adjacent sets of support frames within a certain range.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, a handle 14 is connected to the outer wall of the middle part of the first internally threaded tube 4. The handle 14 facilitates the rotation of the first internally threaded tube 4.

[0029] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the bottom of the top frame 2 is fixedly connected to two symmetrical mounting plates 15. Reinforcing ribs 16 connect the mounting plates 15 and the top frame 2. The mounting plates 15 and the columns 1 are connected to each other by bolts. Several first connecting holes 17 are opened on the top sidewall of the side of the two columns 1 that are close to each other. Several second connecting holes 18 are opened on the mounting plates 15. The first connecting holes 17 and the second connecting holes 18 are evenly distributed vertically. By setting up the mounting plates 15, the mounting plates 15 and the columns 1 are connected to each other by bolts, facilitating installation and removal. Furthermore, the large number of first connecting holes 17 and second connecting holes 18 ensures that the top frame 2 can be stably connected by bolts after it is raised or lowered.

[0030] In this embodiment, as Figure 3 , Figure 4 and Figure 6As shown, both ends of the bottom of the column 1 are fixedly connected to a second screw 19. The bottom of the second screw 19 is threadedly connected to a second internally threaded tube 20 rotatably mounted on the column 1. A fixing plate 21 is fixedly connected to the middle of the column 1. A second rotating hole 22 is opened in the middle of the fixing plate 21. A rotating rod 23 rotatably connected to the second rotating hole 22 is fixedly connected to the bottom of the second internally threaded tube 20. A hexagonal head 24 located at the bottom of the fixing plate 21 is fixedly connected to the bottom of the rotating rod 23. By setting the second screw 19, the second internally threaded tube 20, the rotating rod 23, and the hexagonal head 24, the top frame 2 can be raised and lowered by rotating the second internally threaded tube 20. In use, an electric wrench is used to rotate the second internally threaded tube 20 on both sides to raise and lower the top frame 2, and then bolts are used for connection.

[0031] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the support and reinforcement device for mine tunnels provided in this embodiment is as follows:

[0032] Step 1: During installation, use an electric wrench to rotate the second internal threaded pipe 20 on both sides to raise the top frame 2, and then use bolts to connect the mounting plate 15 and the column 1;

[0033] Step 2: Install the support plate 5, squeeze the protruding rod 8 to compress the spring 9, so that the rotating block 6 is placed between the upper and lower bosses, so that the protruding rods 8 at both ends of the support plate 5 enter the first rotating hole 12 and the sliding groove 13 respectively;

[0034] Step 3: Rotate the first internal threaded tube 4 to engage with the first screw 3, and adjust the distance between the two adjacent sets of support frames.
