Description

Technical Field

[0001] This utility model relates to the field of mine support technology, specifically a support safety protection device for underground copper mining. Background Technology

[0002] Copper mining underground refers to a method of mining through underground tunnels and shafts. This method is suitable for situations where the ore body is buried deep, the scale is small, or the surface environment needs to be protected. Underground mining is technically difficult, but since most copper mines are buried underground, this method must be used. Copper mining sites are mostly located in mountainous or mountainous areas with complex geological conditions and a high risk of geological disasters. Therefore, underground support and protection equipment is very important for copper mining.

[0003] Currently, after the installation of some underground support equipment, the mine wall can be shielded and protected to prevent deformation or collapse. However, when slight deformation occurs in the mine wall, it is difficult for workers to detect it. Furthermore, due to the protection provided by some support equipment, workers also have difficulty detecting falling rocks, which affects the timeliness of worker evacuation and may even cause greater losses. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-8As shown, a support safety protection device for underground copper mining includes two symmetrically arranged support plates 1, an mounting plate 2 fixedly connected to the surface of the support plates 1, and bolts installed on the top of the mounting plate 2. The top of the support plate 1 has a slot 3, and the inside of the support plate 1 has a cavity. An adjustment mechanism 4 is installed inside the cavity. A turntable 5 is fixedly fitted on the surface of the adjustment mechanism 4. The surface of the turntable 5 is in contact with the inner wall of the slot 3. An outer arc plate 6 is fixedly connected to the top of the turntable 5. A fixing block 7 is fixedly connected to the surface of the turntable 5. An inner arc plate 8 is fixedly connected to the top of the fixing block 7. A horizontal plate 9 is fixedly connected to one end of the inner arc plate 8. A force-bearing mechanism 10 is installed on the top of the horizontal plate 9. A storage plate 13 is fixedly connected to the bottom of the horizontal plate 9. A pressure alarm 14 is installed on the bottom of the inner surface of the storage plate 13. There are two horizontal plates 9. A rotating shaft 15 is fixedly connected to the bottom of one horizontal plate 9. A sleeve rod 16 is rotatably fitted on the surface of the rotating shaft 15. An auxiliary mechanism 17 is installed at the bottom of the other horizontal plate 9.

[0026] The adjustment mechanism 4 includes an adjustment rod 41, a worm gear 42, and a worm 43. One end of the adjustment rod 41 is rotatably connected to the inner wall of the slot 3, and the other end of the adjustment rod 41 is rotatably connected to the inner wall of the cavity. The worm gear 42 is fixedly sleeved on the surface of the adjustment rod 41. The bottom of the worm 43 is rotatably connected to the bottom of the inner wall of the cavity, and the top of the worm 43 rotatably extends through to the top of the support plate 1. The worm 43 meshes with the worm gear 42. The turntable 5 is fixedly sleeved on the surface of the adjustment rod 41. When the operator rotates the worm 43, the worm 43 and the worm gear 42 work together to drive the adjustment rod 41 to rotate, thereby adjusting the state of the turntable 5. This makes it easier for the operator to move the device and install it at a designated location.

[0027] The force-bearing mechanism 10 includes a smooth rod 101, a force-bearing plate 102, and a first compression spring 103. The smooth rod 101 slides through the top of the horizontal plate 9. The force-bearing plate 102 is fixedly connected to the top of the smooth rod 101. The first compression spring 103 is sleeved on the surface of the smooth rod 101. The two ends of the first compression spring 103 are fixedly connected to the top of the horizontal plate 9 and the bottom of the force-bearing plate 102, respectively. When the top of the mine is deformed, the force-bearing plate 102 will be forced to lower the smooth rod 101. When the smooth rod 101 is lowered to a certain height, it will contact the top of the pressure alarm 14 and squeeze the pressure alarm 14. At this time, the pressure alarm 14 will sound an alarm to warn the surrounding staff.

[0028] A T-shaped plate 11 is fixedly connected to the surface of the load-bearing plate 102. A T-shaped groove 12 is opened on the surface of the outer arc plate 6. The surface of the T-shaped plate 11 is in contact with the inner wall of the T-shaped groove 12. The stability of the load-bearing plate 102 during movement can be increased by the cooperation of the T-shaped plate 11 and the T-shaped groove 12.

[0029] The diameter of the bottom of the light rod 101 is larger than the diameter of the top of the light rod 101, and the diameter of the bottom of the light rod 101 is larger than the diameter of the top of the press alarm 14. This makes it easier for the light rod 101 to be used in conjunction with the press alarm 14.

[0030] The auxiliary mechanism 17 includes a vertical plate 171, a sliding rod 172, an auxiliary block 173, and a second compression spring 174. The vertical plate 171 is fixedly connected to the bottom of the horizontal plate 9, the sliding rod 172 is fixedly connected to the surface of the vertical plate 171, the top of the auxiliary block 173 is slidably connected to the bottom of the horizontal plate 9, the auxiliary block 173 is slidably sleeved on the surface of the sliding rod 172, the second compression spring 174 is sleeved on the surface of the sliding rod 172, and the two ends of the second compression spring 174 are fixedly connected to the surfaces of the vertical plate 171 and the auxiliary block 173, respectively. The inner surface of the sleeve rod 16 is in contact with the surface of the auxiliary block 173. When the operator pulls and moves the auxiliary block 173, the auxiliary block 173 moves under the action of the elastic force of the second compression spring 174 and cooperates with the sleeve rod 16 to restrict the position of the sleeve rod 16, thereby reinforcing the connection between the two horizontal plates 9.

[0031] Working principle: After the operator moves the device to the designated location, one of the support plates 1 can be bolted to the ground of the mine. Then, the operator can rotate the worm 43. The worm wheel 42 and the worm 43 work together to drive the adjusting rod 41 to rotate. The adjusting rod 41 and the turntable 5 work together to drive the outer arc plate 6 to rotate. The outer arc plate 6 and the force plate 102 work together to support and protect the side wall and top of the mine. Then, the operator rotates the other worm 43. After the other outer arc plate 6 rotates with the turntable 5, the operator can move the other support plate 1 to arrange the two support plates 1 symmetrically. Then, the operator can pull the auxiliary block 173 while rotating the sleeve rod 16. Then, under the action of the second compression spring 174, the sleeve rod 16 and the auxiliary block 173 work together to connect the two horizontal plates 9.

[0032] When deformation occurs at the top of the mine, the force plate 102 is subjected to force, causing the guide rod 101 to descend. The guide rod 101 works in conjunction with the pressure alarm 14. When the pressure alarm 14 is applied, it will sound an alarm to remind the surrounding workers, so as to warn them in time and facilitate their rapid evacuation, thereby improving the safety of mining operations.
