Description

Technical Field

[0001] The utility model relates to the technical field of mining protection, in particular to a protection device for coal mine back mining. Background Technique

[0002] Coal mines are one of the important energy resources, mainly used for power generation and heating. As a kind of fossil energy, coal can provide a large amount of heat energy and is used as fuel for power plants. Many countries around the world still rely on coal as the main power source, especially in regions where energy demand is growing rapidly or other alternative energy resources are insufficient. Coal is also used as a raw material for industrial production. For example, coke is an important metallurgical raw material used in the production of steel and ferroalloys. In addition, coal can also be used as a chemical raw material, such as in the manufacture of synthetic ammonia, synthetic oil, etc. Coal mines need to be mined in underground mines, but underground mines may collapse, so protection devices are required.

[0003] During the coal mine back mining process, the rock strata and coal seams in the mine may collapse. Therefore, structures such as pillars, steel frames or concrete are used for support and reinforcement to maintain the stability and safety of the roadway. Combustible gas is generated in coal mines. To prevent its accumulation from causing an explosion, a gas drainage system and gas detection instruments are set up. The gas drainage system extracts and discharges the gas to a safe area through pipelines to ensure fresh air in the mine. A large amount of coal dust is generated during coal mine mining. To reduce the impact of coal dust on the health of workers, a wet spray system or water-containing dust coal is used for the prevention and treatment of pneumoconiosis to effectively control the coal dust dust.

[0004] Traditional protection devices usually rely on structures such as pillars, steel frames or concrete to support and reinforce the mine to ensure the structural stability and safety of the mine. However, traditional protection devices are not flexible enough. These devices can usually only be fixed at a certain height by pillars and cannot be flexibly adjusted or adapted to different geological and working environment changes. The material selection and construction technology of traditional protection devices may also limit their applicability in different environments. Content of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a protection device for coal mine back mining, aiming to improve the problems that traditional protection devices cannot be flexibly adjusted or adapted to different geological and working environment changes and their applicability in different environments.

A connecting plate is fixedly connected to the outer wall of the second support column. Another second support column is fixedly connected inside the connecting plate. A shielding plate is fixedly connected to the top of each second support column. A fixing component is arranged inside the machine body, and the fixing component is used to fix the shielding plate on the top of the machine body.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figures 1 - 4 , an embodiment provided by the present invention: a protection device for coal mine back mining, including a machine body 1 and a T-shaped plate 20. A plurality of first support columns 8 are fixedly connected inside the machine body 1. A push rod 2 is fixedly connected inside one of the first support columns 8. The output end of the push rod 2 is fixedly connected with a moving column 5. A plurality of fixing blocks 4 are fixedly connected to the outer wall of the moving column 5. A plurality of grooves 3 are formed inside the first support column 8. One end of each fixing block 4 is slidably connected inside the groove 3. A connecting column 6 is fixedly connected to the top of the moving column 5. A first spring 7 is sleeved on the outer wall of the connecting column 6. The top of the connecting column 6 is fixedly connected with a second support column 10. One end of the first spring 7 is fixedly connected to the top of the T-shaped plate 20, and the other end of the first spring 7 is fixedly connected to the bottom of the second support column 10. A connecting plate 9 is fixedly connected to the outer wall of the second support column 10. Another second support column 10 is fixedly connected inside the connecting plate 9. A shielding plate 11 is fixedly connected to the top of each second support column 10. A fixing component is arranged inside the machine body 1, and the fixing component is used to fix the shielding plate 11 on the top of the machine body 1.

[0027] Specifically, the push rod 2 is used to push the moving column 5. Since the fixing blocks 4 on the moving column 5 are inside the grooves 3, with the continuous pushing of the push rod 2, the moving column 5 stably slides inside the first support column 8, thereby driving the connecting column 6 to move, and then driving the second support column 10 to move. During this process, the first spring 7 on the connecting column 6 is connected to the moving column 5 and the second support column 10. The first spring 7 can relieve the pressure on the connecting column 6 and ensure that the second support column 10 can move stably. In view of the connecting plate 9 connecting a plurality of second support columns 10, each second support column 10 drives the shielding plate 11 to move simultaneously, ensuring that the shielding plate 11 can move vertically smoothly and precisely, thereby improving the operation flexibility of the device and enhancing its adaptability in different working environments.

[0028] Refer to Figure 5 and Figure 6, the fixing component includes a fixing plate 21 which is fixedly connected inside the machine body 1. A plurality of concave blocks 14 are fixedly connected to the side wall of the fixing plate 21. A T-shaped block 13 is slidably connected to the outer wall of the fixing plate 21. The inner wall of the T-shaped block 13 is slidably connected to the side wall of the concave block 14. A connecting block 22 is rotatably connected to the side wall of the fixing plate 21. A chute 15 is formed in the side wall of the T-shaped block 13. A plurality of fixing columns 16 are fixedly connected inside the connecting block 22. The side wall of another concave block 14 is fixedly connected to the side wall of the fixing plate 21. A chute 15 is formed in the side wall of the T-shaped block 13. A plurality of fixing columns 16 are fixedly connected inside the connecting block 22. The side wall of another concave block 14 is fixedly connected to the side wall of the fixing plate 21. One end of the fixing column 16 is slidably connected inside the chute 15. A plurality of sliders 18 are slidably connected to the side wall of the concave block 14. A pressing plate 19 is fixedly connected to the side wall of the T-shaped block 13. A T-shaped plate 20 is fixedly connected to the side wall of the T-shaped block 13. One end of the fixing column 16 is fixedly connected to the side wall of the slider 18. A clamping plate 17 is fixedly connected to the side wall of the slider 18. A chute 15 is formed in the side wall of the pressing plate 19. A second spring 12 is fixedly connected to the side wall of the pressing plate 19. One end of the second spring 12 is fixedly connected to the side wall of the T-shaped plate 20, and the other end of the second spring 12 is fixedly connected to the side wall of the pressing plate 19.

[0029] Specifically, by pressing the T-shaped block 13, the T-shaped block 13 starts to move in the chute 15. The T-shaped block 13 is connected to the connecting block 22 through the fixing column 16. The position of the fixing column 16 ensures the stability of the connecting block 22. As the T-shaped block 13 moves, the inclination angle of the connecting block 22 changes, which in turn affects another fixing column 16, pushing the slider 18 to move inside the device. The movement of the slider 18 guides the clamping plate 17 to perform corresponding actions, enabling the clamping plate 17 to remain open when needed, thus ensuring the flexibility and reliability of the clamping plate 17 during operation. As the pressing on the T-shaped block 13 is released, the built-in second spring 12 acts as a reaction force, pushing the clamping plate 17 to quickly clamp, making the replacement and maintenance operations of the monitoring device more convenient and greatly reducing the possible mistakes and risks during the operation.

[0030] Working principle: The push rod 2 is used to push the moving column 5. The fixed block 4 on the moving column 5 is firmly installed inside the groove 3, which ensures that during the continuous pushing of the push rod 2, the moving column 5 can stably slide inside the first support column 8. The movement of the moving column 5 drives the connecting column 6 to start moving, thereby affecting the position of the second support column 10. On the connecting column 6, the first spring 7 is connected to the moving column 5 and the second support column 10, so that the first spring 7 relieves the pressure on the connecting column 6 and ensures the stability of the movement of the second support column 10. The connecting plate 9 connects multiple second support columns 10, so the movement of each second support column 10 can synchronously affect the position of the shielding plate 11. The vertical movement of the shielding plate 11 is precise and stable, thereby improving the operation flexibility of the device and significantly enhancing its adaptability in different working environments. By pressing the T-shaped block 13, the T-shaped block 13 starts to move. Since the T-shaped block 13 is connected to the connecting block 22 through the fixed column 16, and the fixed column 16 is in the sliding groove 15, as the T-shaped block 13 moves, it pushes the connecting block 22 to change the inclination angle, and then pushes the slider 18 to move through another fixed column 16, immediately driving the clamping plate 17 to move, so that the clamping plate 17 is in an open state. As the T-shaped block 13 is pressed, the second spring 12 generates a reaction force, so that the clamping plate 17 clamps, making the replacement and maintenance of the monitoring device more convenient.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
