Description

Technical Field

[0001] The present invention relates to the field of safety protection technology, and in particular to a safety protection device for mineral geological engineering and a use method thereof. Background Art

[0002] Mineral geological engineering often involves deep well operations, open-pit mining and other scenarios, which have many potential safety hazards, such as unstable geological structures, toxic and harmful gases, dim light conditions, etc. In order to protect the lives of workers and improve production efficiency, it is particularly important to use special safety protection devices. These devices can not only effectively monitor geological changes and warn of potential risks, but also provide necessary protection and self-rescue measures in emergency situations.

[0003] After searching, the invention patent with Chinese patent number CN113605944A discloses a safety protection device for mineral exploration. Compared with the prior art, the invention patent with Chinese patent number CN113605944A provides temporary support for the comprehensive excavation working face. In terms of driving mode, the ground-supporting hydraulic cylinder and the telescopic hydraulic cylinder can work alternately. The head protection shield can be folded horizontally using the movable block to save space. In the working state, the head protection shield can be propped up to support the front coal wall to facilitate the retreat of the tunneling machine and the entry and work of the staff. At the same time, the arc-shaped frame at the top can fit with the arched tunnel, so as to better support and prevent the sudden collapse of the working face from threatening the life safety of the workers.

[0004] However, in the actual use of the above-mentioned device, the design of the safety protection device for mineral exploration obviously focuses on the comprehensive protection of the entire operating area. Through the sophisticated mechanical structure and hydraulic system, it provides a solid support barrier for the excavation operation, effectively preventing major safety risks such as tunnel collapse. However, while emphasizing overall protection, the device ignores the direct protection of individual workers. The direct protection of individual workers can greatly reduce their direct exposure to potential dangers such as falling rocks and flying debris, thereby ensuring their life safety. Therefore, it is necessary to propose a safety protection device for mineral geological engineering and a method of use. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the existing devices in the prior art ignore the direct protection of individual workers, and to greatly reduce the risk of their direct exposure to potential danger sources such as falling rocks and flying debris in the complex and changeable environment of mineral exploration, and to propose a safety protection device and method of use for mineral geological engineering.

The start of the motor 11 will drive the second gear 13 to rotate. The rotation of the second gear 13 will drive the first gear 5 to rotate. The rotation of the first gear 5 will drive the sliding rod 8 to slide along the inner side of the first sliding groove 6. The movement of the sliding rod 8 will drive the moving block 9 to move. The movement of the moving block 9 will drive the protection plate 15 to expand away from the pentagonal plate 4. The movement of the protection plate 15 will drive the arcuate plate 16 to move. The movement of the arcuate plate 16 can buffer the impact from the outside. A safety anti-collision assembly is provided on the outside of the arcuate plate 16. The safety anti-collision assembly includes a sliding strip 17, a spring 19, a sliding block 20 and a flexible plate 21 provided on the arcuate plate 16. When the flexible plate 21 is impacted from the outside, it will drive the sliding block 20 to slide on the outside of the sliding strip 17. The sliding block 20 will squeeze the spring 19. The spring 19 will offset the impact received on the outside of the flexible plate 21. A handrail 24 is movably connected to the side of the first gear 5 away from the top layer protection plate 1.

[0031] A fixing rod 2 is fixedly connected to the side of the top layer protection plate 1 close to the pentagonal plate 4. One end of the fixing rod 2 away from the top layer protection plate 1 is fixedly connected to the pentagonal plate 4. An annular tube 3 is rotatably connected to the outside of the fixing rod 2. The outside of the annular tube 3 is fixedly connected to the first gear 5. The function of the annular tube 3 is to connect the fixing rod 2 and the pentagonal plate 4.

[0032] A plurality of first sliding grooves 6 are formed inside the first gear 5. The plurality of first sliding grooves 6 are evenly distributed in a circular pattern along the first gear 5. The inner side of the first sliding groove 6 is slidably connected to the sliding rod 8. The rotation of the first gear 5 will drive the sliding rod 8 to move inside the first sliding groove 6.

[0033] A limiting block 7 is fixedly connected to the end of the sliding rod 8 away from the pentagonal plate 4. One end of the sliding rod 8 away from the limiting block 7 is fixedly connected to the moving block 9. A plurality of groups of second sliding grooves 10 are formed inside the pentagonal plate 4.

The end of the triangular block 14 away from the moving block 9 is fixedly connected with a guard plate 15. The side of the guard plate 15 away from the top guard plate 1 is fixedly connected with an arcuate plate 16.

[0035] The side of the top guard plate 1 close to the fixed rod 2 is fixedly connected with a motor 11. The end of the output shaft of the motor 11 is fixedly connected with a rotating rod 12. The end of the rotating rod 12 away from the motor 11 is fixedly connected with a second gear 13. The second gear 13 meshes with the first gear 5.

[0036] The outside of the arcuate plate 16 is fixedly connected with a sliding bar 17. Both ends of the sliding bar 17 are fixedly connected with fixing blocks 18.

[0037] A method for using a safety protection device for mineral geological engineering:

[0038] Step 1: First, when the device is impacted from the outside, the first part to be impacted is the flexible plate 21. When the flexible plate 21 is impacted, the flexible plate 21 will deform. The flexible plate 21 will push the sliding block 20 to slide on the outside of the sliding bar 17. The sliding block 20 will squeeze the spring 19, and the spring 19 will buffer part of the impact force.

[0039] Step 2: When the flexible plate 21 is impacted by an external impact force, it will drive the arcuate plate 16 to move towards the side close to the pentagonal plate 4. The movement of the arcuate plate 16 will push the moving block 9 to slide inside the pentagonal plate 4. While the moving block 9 is sliding, it will push the sliding rod 8 to slide inside the first sliding groove 6.

[0040] Step 2: The sliding of the sliding rod 8 in the first sliding groove 6 can buffer the impact force received by the arcuate plate 16. When it is necessary to expand the arcuate plate 16 outwards, start the motor 11. The start of the motor 11 will drive the second gear 13 to rotate. The rotation of the second gear 13 will drive the first gear 5 to rotate. The rotation of the first gear 5 will drive the arcuate plate 16 to expand outwards, realizing the recycling of the device.

[0041] In this embodiment, the start of the motor 11 drives the second gear 13 to rotate. The rotation of the second gear 13 drives the first gear 5 to rotate. The rotation of the first gear 5 drives the sliding rod 8 to slide along the inner side of the first sliding groove 6. The movement of the sliding rod 8 drives the moving block 9 to move. The movement of the moving block 9 drives the guard plate 15 to expand away from the pentagonal plate 4. The movement of the guard plate 15 drives the bow-shaped plate 16 to move. The movement of the bow-shaped plate 16 can buffer the impact from the outside. The specific implementation is that the fixed rod 2 is used to connect the top guard plate 1 and the annular tube 3. The annular tube 3 is used to connect the fixed rod 2 and the pentagonal plate 4. When in use, the start of the motor 11 drives the rotating rod 12 to rotate. The rotation of the rotating rod 12 drives the second gear 13 to rotate. The rotation of the second gear 13 drives the first gear 5 to rotate. The rotation of the first gear 5 drives the sliding rod 8 to move inside the first sliding groove 6. The movement of the sliding rod 8 drives the moving block 9 to move inside the second sliding groove 10. The limiting block 7 is used to connect the sliding rod 8, and the limiting block 7 can play a role in limiting the sliding rod 8. When the moving block 9 moves, it pushes the triangular block 14 to move away from the pentagonal plate 4. When the triangular block 14 moves, it pushes the bow-shaped plate 16 to move away from the pentagonal plate 4. The movement of the bow-shaped plate 16 can buffer the impact from the outside, so as to protect a single staff member and prevent risks from potential hazard sources such as falling stones and flying debris.

[0042] Embodiment Two

[0043] As Figures 1-7 shown, based on Embodiment One, a fixed connection is formed between one end of the fixed block 18 close to the sliding strip 17 and the spring 19. A fixed connection is formed between the end of the spring 19 far from the fixed block 18 and the sliding block 20. A fixed connection is formed between the two sliding blocks 20 and the flexible plate 21 together. The sliding block 20 is slidably connected to the sliding strip 17. The sliding block 20 squeezes the spring 19, and the spring 19 offsets the impact received on the outside of the flexible plate 21.

[0044] Symmetrically fixed connections are formed at the lower part of the pentagonal plate 4 with two telescopic rods 22. A cross plate 23 is fixedly connected between the two telescopic rods 22. A fixed connection is formed between the side of the cross plate 23 far from the top guard plate 1 and the handrail 24. The number of the handrails 24 is two.

[0045] In this embodiment, when the flexible plate 21 is impacted from the outside, it drives the sliding block 20 to slide on the outside of the sliding strip 17. The sliding block 20 squeezes the spring 19, and the spring 19 offsets the impact received on the outside of the flexible plate 21, so as to protect a single staff member. The specific implementation is that when the device is impacted from the outside, the first part to be impacted is the flexible plate 21. When the flexible plate 21 is

[0046] When impacted, the flexible plate 21 will deform. The flexible plate 21 will push the sliding block 20 to slide outside the sliding bar 17. The sliding block 20 will exert extrusion on the spring 19, and the spring 19 will buffer part of the impact force. When the flexible plate 21 is impacted by an external force, it will drive the bow-shaped plate 16 to move towards the side close to the pentagonal plate 4. The movement of the bow-shaped plate 16 will push the moving block 9 to slide inside the pentagonal plate 4. While sliding, the moving block 9 will push the sliding rod 8 to slide inside the first sliding groove 6.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
