Technical Field

[0001] The invention relates to the technical field of mine tunnel support, and in particular to a mine tunnel support device. Background Art

[0002] The basic purpose of supporting the tunnel is to ease and reduce the movement of the surrounding rock so that the tunnel section does not shrink excessively, and at the same time prevent the scattered and damaged surrounding rock from falling. The effect of tunnel support depends not only on the supporting force of the support itself, but also on a series of factors such as the properties of the surrounding rock, the mechanical properties of the support including supporting force, contractibility, support installation density, the time of support installation, the quality of support installation and the contact mode with the surrounding rock. The contact mode is point contact or surface contact.

[0045] In this embodiment, the function of the multiple reserved blocks 30 is to connect the support members between the adjacent first arc frame 1 and the second arc frame 2. The support members can be made of steel plates, and both ends of the support members are installed on the mounting holes 34. When an accident occurs, the top of the mine tunnel can be supported to form a certain space locally, thereby reducing the possibility of miners being buried by landslides.

[0047] In this embodiment, the fixing nails 6 are driven into the ground to fix the position of the fixing plate 5, so that the first arc frame 1 and the second arc frame 2 have fixed fulcrums.

[0049] In this embodiment, a mining track can be installed on the track plate 4. There are multiple degrees of freedom between the track plate 4 and the fixed block 10, which can reduce the deformation of the track caused by the deformation of the mine tunnel. At the same time, the track plate 4 and the fixed block 10 serve to connect the adjacent first arc frame 1 and the second arc frame 2, so that the device becomes a whole.

[0050] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the variable support rod mechanism includes an upper connecting seat 13 fixedly connected to the middle position of the first arc frame 1 and the second arc frame 2, the bottom of the upper connecting seat 13 is rotatably connected to an upper internal threaded frame 14, the bottom of the upper internal threaded frame 14 is threadedly connected to an upper threaded rod 15, the bottom end of the upper threaded rod 15 is fixedly connected to a hexagonal column 16, the bottom of the hexagonal column 16 is fixedly connected to a lower threaded rod 17, the bottom end of the lower threaded rod 17 is threadedly connected to a lower internal threaded frame 18, and the bottom of the lower internal threaded frame 18 is rotatably connected to a lower connecting seat 20;

[0051] A sliding fulcrum mechanism is installed at the bottom of the lower connecting seat 20, and the sliding fulcrum mechanism is used to change the fulcrum position.

[0052] In this embodiment, the upper threaded rod 15 and the lower threaded rod 17 are rotated by rotating the hexagonal column 16 with a wrench. Since the threads on the upper threaded rod 15 and the lower threaded rod 17 are in opposite directions, the distance between the upper internally threaded frame 14 and the lower internally threaded frame 18 can be adjusted, and the distance between the upper internally threaded frame 14 and the lower internally threaded frame 18 is increased. The supporting force between the first arc frame 1, the second arc frame 2 and the sliding fulcrum block 19 continues to increase, so that the gap between the first arc frame 1 and the second arc frame 2 and the top mine channel becomes smaller, and there is a certain pre-tightening force, so that the position of the first arc frame 1 and the second arc frame 2 is more stable.

[0053] Reference Figure 1 , Figure 4 , Figure 5 and Figure 8 In a preferred embodiment, the sliding fulcrum mechanism includes a sliding fulcrum block 19 fixedly connected to the bottom of the lower connecting seat 20, and a slide plate 3 is slidably connected to both sides of the sliding fulcrum block 19. A plurality of fixed teeth 22 are fixedly connected to the bottom upper surface of the slide plate 3, and a plurality of positioning holes 21 are respectively designed on the bottom upper surface of the slide plate 3 near both ends.

[0054] Two grooves are arranged at the bottom of the sliding fulcrum block 19 , and clamping blocks 23 are rotatably connected inside the grooves respectively. A rotation spring 24 is fixedly connected to an outer wall of one side of the clamping block 23 .

[0055] The first arc frame 1 is hollow inside, and the first arc frame 1 and the second arc frame 2 have the same structure. The rotating short column 28 at the top of the first arc frame 1 is rotatably connected to the rotating short column 28 at the top of the second arc frame 2, and the ball head 31 can rotate at multiple angles inside the ball shell 26.

[0056] The outside of the air pipe 7, water pipe 8 and wire pipe 9 are respectively provided with insulating coatings, the other end of the rotary spring 24 is fixedly connected to the sliding fulcrum block 19, and a plurality of first arc frames 1 and second arc frames 2 are connected end to end, playing a skeleton support role inside the mine tunnel.

[0057] In this embodiment, when fixing the first arc frame 1 and the second arc frame 2, it is necessary to first fix the position of the slide plate 3, and the slide plate 3 is fixed on the ground by drilling holes in the ground and fixing the slide plate 3 with bolts inside the positioning holes 21. The slide plate 3 is then fixed on the ground by hitting the side of the sliding fulcrum block 19 with a hammer to make the sliding fulcrum block 19 slide inside the slide plate 3. Due to the design of the clamping block 23 and the fixed tooth 22, when the sliding fulcrum block 19 slides forward, the clamping block 23 rotates to compress the return spring 24. The sliding fulcrum block 19 moves forward one more fixed tooth 22. Due to the design of the groove on the sliding fulcrum block 19, the clamping block 23 cannot rotate in the opposite direction, so that the sliding fulcrum block 19 cannot slide backward, thereby fixing the sliding fulcrum block 19 and increasing the supporting force for the first arc frame 1 and the second arc frame 2.

[0058] Working principle: When in use, multiple first arc frames 1 and second arc frames 2 are connected end to end, and play a role of skeleton support inside the mine tunnel. Since multiple first arc frames 1 and second arc frames 2 are connected end to end to form a whole, a spring-like structure supports the inside of the pipeline. When the mine tunnel collapses, the spring-type structure made of multiple first arc frames 1 and second arc frames 2, and the design of rotating short columns 28 and mounting seats 29 make the connection between the first arc frame 1 and the second arc frame 2 have multiple degrees of freedom, and the connection will not break. Under the shear force generated by the collapse and deformation of the mine tunnel, the multi-degree-of-freedom design and the structure of the first arc frame 1 and the second arc frame 2 can maintain the connection between the first arc frame 1 and the second arc frame 2. The frame 1 and the second arc frame 2 are internally installed with an air pipe 7, a water pipe 8 and a wire pipe 9. The air pipe 7 plays a role in ventilation, the water pipe 8 plays a role in water flow, and the wire pipe 9 plays a role in electricity flow, so that people trapped in the mine tunnel have sufficient water and air, as well as electricity to support the use of communication equipment and lighting, which relieves the pressure of mine rescue and ensures the life safety of miners, so that miners can hold on until rescuers arrive, thereby increasing the survival rate of miners in mine accidents. In the mine tunnel, various machines and excavation reasons cause the vibration of the mine tunnel, driving the first arc frame 1 and the second arc frame 2 to squeeze each other. The first arc frame 1 and the second arc frame 2 respectively pull the ball head 31 and the buffer rod 32 through the ball shell 26, thereby compressing the buffer spring 33, so that the ... The frame 1 and the second arc frame 2 are close to the wall of the mine tunnel, which reduces the rock stratum shedding caused by vibration in the mine tunnel. The function of multiple reserved blocks 30 is to connect the support members between the adjacent first arc frame 1 and the second arc frame 2. The support members can use steel plates. Both ends of the support members are installed on the mounting holes 34. When an accident occurs, the top of the mine tunnel can be supported to form a certain space locally, which reduces the possibility of miners being buried by landslides. The position of the fixing plate 5 is fixed by driving the fixing nails 6 into the ground, so that the first arc frame 1 and the second arc frame 2 have fixed fulcrums. The mine track can be installed on the track plate 4. There are multiple degrees of freedom between the track plate 4 and the fixing block 10, which can reduce the deformation of the track caused by the deformation of the mine tunnel. At the same time, the track plate 4 and the fixing block 10 play a role in To connect the adjacent first arc frame 1 and the second arc frame 2, so that the device becomes a whole. When fixing the first arc frame 1 and the second arc frame 2, it is necessary to first fix the position of the slide plate 3, by drilling holes on the ground and fixing them inside the positioning holes 21 with bolts, so that the slide plate 3 is fixed on the ground. By using a hammer to hit the side of the sliding fulcrum block 19, the sliding fulcrum block 19 slides inside the slide plate 3. Due to the design of the clamping block 23 and the fixed tooth 22, when the sliding fulcrum block 19 slides forward, the clamping block 23 rotates and compresses the return spring 24. The sliding fulcrum block 19 moves forward one more fixed tooth 22. The design of the groove on the sliding fulcrum block 19 prevents the clamping block 23 from rotating in the opposite direction, so that the sliding fulcrum block 19 cannot slide backward.It plays the role of fixing the sliding fulcrum block 19, and increases the supporting force of the first arc frame 1 and the second arc frame 2. After completion, it is necessary to use a wrench to rotate the hexagonal column 16 to rotate the upper threaded rod 15 and the lower threaded rod 17. Since the threads on the upper threaded rod 15 and the lower threaded rod 17 are in opposite directions, the distance between the upper internal threaded frame 14 and the lower internal threaded frame 18 can be adjusted, and the distance between the upper internal threaded frame 14 and the lower internal threaded frame 18 can be increased. The supporting force between the first arc frame 1, the second arc frame 2 and the sliding fulcrum block 19 continues to increase, so that the gap between the first arc frame 1 and the second arc frame 2 and the top mine channel becomes smaller, and there is a certain pre-tightening force, which makes the position of the first arc frame 1 and the second arc frame 2 more stable. ,
