Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective components used in lead-zinc ore mining, in particular to a protective structural component used in lead-zinc ore mining. Background Art
[0002] Protective structures are crucial in lead-zinc ore mining, primarily to prevent head injuries from accidents such as falling ore and tool collisions. In underground tunnels, loose rocks or ore blocks may fall off, and hard hats can protect against direct impacts from these objects. For example, when miners are working near the face (the worksite where ore is mined), hard hats can effectively protect their heads from falling ore from above.
[0003] At present, the protective structural parts used in lead and zinc ore mining are to protect the top and both sides of the mine through support nets. However, the support nets are currently only fixed by square fixings during installation. When gravel falls, the support nets bear a large gravity, and when the gravity is transferred to the square fixings, the stability of the fixings is poor, which makes it easy for the fixings to fall off due to instability. Utility Model Content
[0004] The purpose of the utility model is to provide a protective structural member for lead-zinc ore mining to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective structural member for lead-zinc ore mining, comprising a support plate, a connecting block for connection is provided on the inner side of the support plate, an arc-shaped plate is provided on the inner side of the connecting block, a fixing member is provided through the inner side of the arc-shaped plate, a flat plate is provided on the top of the arc-shaped plate, and a support assembly for supporting and fixing the support net at the top of the mine is provided on the top of the flat plate.
[0006] Preferably, a threaded hole is provided inside the connecting block.
[0007] Preferably, a through hole is opened inside the bottom end of the arc-shaped plate.
[0008] Preferably, the arc-shaped plate is made of high-strength metal.
[0009] Preferably, the support assembly includes an auxiliary rotating rod, which is arranged on both sides of the top of the flat plate, a connecting plate is provided at the top of the auxiliary rotating rod, a double-headed stud is threadedly provided at the center of the connecting plate, a supporting top rod is provided at the top of the connecting plate, and a fixing plate for fixing the support net is provided at the top of the supporting top rod.
[0010] Preferably, a threaded hole is provided at the center of the connecting plate, which is used to drive the stud to move inward when it rotates.
[0011] Preferably, the fixing plate is in an arc shape, so as to facilitate supporting the support net at the top of the mine.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] This protective structure is based on the support plate and is connected to the high-strength metal curved plate through connecting blocks and fixings. This connection method makes the entire structure firm and reliable. The threaded holes in the connecting blocks and the through-hole design at the bottom of the curved plate, combined with the fixings, can ensure that the curved plate is stably fixed to the inner side of the support plate, effectively bearing the pressure from the mine, preventing the structure from loosening or deformation, and providing stable support and protection for the mine mining environment.
[0014] The flat plate at the top of the curved plate provides a stable installation platform for the supporting components, further enhancing the stability of the entire protective structure, so that it can maintain good structural integrity under complex and harsh lead-zinc ore mining conditions, such as vibration, ore impact, etc., to ensure the safe progress of mining operations.
[0015] The auxiliary rotating rod, connecting plate, stud, supporting mandrel and fixing plate in the supporting assembly cooperate with each other to effectively support and fix the support net at the top of the mine. When the stud rotates, it drives the connecting plate to move inward. Through the linkage of the auxiliary rotating rod and the supporting mandrel, the curved fixing plate is pushed upward, so that the fixing plate fits tightly against the support net. This design can adapt to the irregular shape of the mine top, ensuring that the support net can be firmly supported at all positions, preventing the rock from falling from the mine top, and improving the safety of the mining operation surface.
[0016] The arc shape of the fixed plate optimizes the contact mode with the support net, increases the contact area, makes the support net more evenly stressed, reduces the possibility of damage to the support net due to excessive local pressure, extends the service life of the support net, and reduces safety hazards and maintenance costs during the mining process.

[0025] Working principle: When a lead-zinc ore mining protective structure is used, the user first lays the support net on the outer wall of the mine, and then the user places the support plate 1 on both sides of the mine, fits the support plate 1 with the support net, and then the user fixes the support plate 1 with bolts, and then the user fits the bottom ends of the two sides of the two curved plates 3 on the surface of the connecting block 2, and then the user fixes the curved plate 3 to the outer wall of the connecting block 2 through the fixing piece 4. After fixing, the user rotates the stud 8, and the connection plate 7 can be driven on both sides by rotating the stud 7. The outer wall of the head stud 8 moves inward at the same time.
