Description

Technical Field

[0001] The invention relates to support equipment technology, and in particular to a buffered lead-zinc mine support equipment and a support method. Background Art

[0002] Lead-zinc ore refers to minerals rich in the metallic elements lead and zinc. Lead and zinc are widely used in the electrical industry, mechanical industry, military industry, metallurgical industry, chemical industry, light industry and pharmaceutical industry. In addition, lead metal is also widely used in the nuclear industry, petroleum industry and other sectors. Zinc is a metal extracted from lead-zinc ore. Zinc is second only to copper and aluminum in the consumption of non-ferrous metals. Zinc metal has good rolling resistance, wear resistance and corrosion resistance, and can be made into alloys with better physical and chemical properties with a variety of metals. The main products produced by primary zinc enterprises are: metallic zinc, zinc-based alloys, and zinc oxide, which are widely used.

[0003] Tunnel support refers to the technical measures taken to support and reinforce the surrounding area of ​​the tunnel during tunnel construction to ensure construction safety, stability and convenience. It can effectively prevent tunnel deformation and collapse, improve construction safety, and ensure the stability of the tunnel structure.

[0004] A Chinese invention patent with publication number CN117868927B discloses a tunnel support device, which does not require welding during use and can be quickly and conveniently assembled through fasteners. Moreover, by setting a first lifting assembly and a second lifting assembly, the height of the first movable plate and the second movable plate can be quickly and flexibly adjusted, thereby adjusting the height of the top plate, so that the tunnel support device can be conveniently adjusted according to the height change of the tunnel, so that the top plate forms a close contact with the top of the tunnel, providing good protection. The use limitations of the tunnel support device have been greatly improved, the construction efficiency of the tunnel project has been improved, and the workload of the workers has been reduced. It has the advantages of simple operation, high efficiency and good applicability. By squeezing the first limit plate and the second limit plate and fixing the bottom of the first limit plate and the second limit plate, the stability of the device can be effectively improved, and the device can be tightly connected to the surrounding strata to form a whole, thereby enhancing the device's resistance to external loads and avoiding displacement and deformation of the device.

[0005] When the existing equipment is in use, the space inside the mine is narrow and the environment is harsh, especially in deep mines or under complex geological conditions.

6. A buffered lead-zinc mine support equipment according to claim 5, characterized in that: The inner wall of the protective plate (42) is provided with a positioning shaft (45), and the outer surface of the positioning shaft (45) is rotatably mounted with an adjustment block (451).

7. A buffered lead-zinc mine support equipment according to claim 6, characterized in that: A first positioning rod (452) and a second positioning rod (453) are rotatably mounted on both ends of the adjustment block (451), and an end of the second positioning rod (453) is rotatably connected to the outer surface of the transmission block (44).

8. A buffered lead-zinc mine support equipment according to claim 7, characterized in that: A clamping block (46) is rotatably mounted on one end of the first positioning rod (452) away from the adjusting block (451), and a connecting block (48) is disposed at the end of the clamping block (46); The outer surface of the end of the connecting block (48) is slidably connected to the inner wall of the supporting block (311).

9. A buffered lead-zinc mine support equipment according to claim 8, characterized in that: Sliding rods (47) are symmetrically arranged at the ends of the protection plate (42), and the outer surfaces of the sliding rods (47) are slidably connected to the inner walls at both ends of the clamping block (46).

10. A buffered lead-zinc mine support method, characterized in that: Using the support equipment according to any one of claims 1 to 9, the support method comprises the following steps: S1. The entire device is transferred to the use position, and the required components are assembled on the support plate (11) in sequence, and the entire device is preliminarily positioned by cooperating with the adjustment column (12) and the positioning plate (13); S2, driving the support component (3) to adjust the angle through the adjustment component (2), so that when the inclination angle of the ore layer is large, it can be attached to the inner wall of the mine hole and support the mine hole; S3. After the support component (3) is adjusted, the protection component (4) supports and buffers the support component (3), thereby keeping the pressure change on the inner wall of the mine cave stable.
