Description

Technical Field

[0001] This utility model relates to the field of mining equipment accessories technology, and in particular to a wear-resistant liner structure for mining accessories. Background Technology

[0002] During mining operations, key components of equipment such as crushers, conveyors, and screening machines are in long-term contact with hard materials such as ore and gravel, and are subjected to strong impacts, friction, and compression, making them prone to wear and failure. As a core component for protecting these parts, wear-resistant liners directly affect the operational stability, maintenance cycle, and mining costs of the equipment.

[0003] Application No. 202320274627.0 specifically discloses a novel wear-resistant liner for mining machinery, comprising a liner body fixedly connected to the outer wall of an outer plate of the mining machinery. A positioning assembly for fixing the liner body is provided on the outer wall of the outer plate of the mining machinery. An inner positioning ring is provided on the liner body corresponding to the positioning assembly. The positioning assembly includes an outer positioning ring fixedly connected to the outer wall of the outer plate of the mining machinery, and a bidirectional lead screw rotatably connected to the outer positioning ring. This utility model, by setting a positioning assembly on the outer plate of the mining machinery, allows the inner positioning ring on one side of the liner body to fit onto the outer positioning ring of the positioning assembly. During use, rotating the bidirectional lead screw on the outer positioning ring moves the telescopic positioning mechanism, thereby allowing the positioning rod on the telescopic block to insert into the positioning hole of the inner positioning ring. This simplifies fixing and solves the problem of inconvenient disassembly and assembly, and consequently, inconvenient maintenance and replacement, of current wear-resistant liners for mining machinery.

[0004] The above-mentioned solution has shortcomings in use. The liner body and the outer plate of the mining machinery are rigidly connected, which has poor impact resistance. When the liner body is hit by large pieces of ore, it is prone to cracks or breakage, thus affecting the protective effect of the liner body. Therefore, we provide a wear-resistant liner structure for mining accessories. Utility Model Content

[0005] This utility model provides a wear-resistant liner structure for mining accessories, which can fully absorb and buffer the impact force received by the liner body, avoid cracks caused by rigid collisions, and thus prevent local breakage or overall damage, ensuring the protective effect of the liner body under long-term impact conditions.

[0006] The purpose and effect of this utility model of a wear-resistant liner structure for mining accessories are achieved by the following specific technical means: a wear-resistant liner structure for mining accessories includes a mining machinery outer plate and a liner body disposed outside the mining machinery outer plate, wherein the mining machinery outer plate and the liner body are connected by a flexible connecting component.

[0007] A buffer assembly is provided between the outer plate of the mining machinery and the liner body to absorb the impact force borne by the liner body. The buffer assembly includes a support plate disposed on one side of the liner body. Two sets of symmetrical piston plates are fixedly connected to one side of the support plate. A piston cylinder is piston-connected to the outside of each piston plate. One end of each piston cylinder is connected to one side of the outer plate of the mining machinery. A spring is fixedly connected to one end of each piston plate and the inner wall of each piston cylinder.

[0008] Preferably, the flexible connection assembly includes a set of insert frames fixedly connected to one side of the outer plate of the mining machinery. Each insert frame has an L-shaped insert plate inserted inside, and each L-shaped insert plate has a connecting frame sleeved on the outside. One side of each connecting frame is connected to one side of the liner body.

[0009] Preferably, one side of each insert frame and one side of each L-shaped insert plate are threadedly connected with a set of bolts.

[0010] Preferably, each of the connecting frames has a set of connecting grooves on both the front and back sides, and a connecting block is slidably connected to the inner wall of each connecting groove. The ends of each set of connecting blocks that are close to each other are respectively connected to the front and back sides of the L-shaped insert plate.

[0011] Preferably, each piston plate has an insertion hole at one end, and a stabilizing rod is slidably connected to the inner wall of each insertion hole. The other end of each stabilizing rod is connected to the inner wall of the piston cylinder, and the stabilizing rod is located inside the spring.

[0012] Preferably, each piston cylinder has an annularly arranged limiting frame fixedly connected to its outer surface, and each limiting frame has a limiting plate slidably connected to its inner wall. The other end of each limiting plate is connected to one side of the abutment plate.

[0013] Preferably, an anti-collision pad is fixedly connected to the other side of the abutment plate.

[0014] Beneficial effects:

[0015] By combining the flexible connecting component with the buffer component, the liner body can be installed on one side of the buffer component using the flexible connecting component. When the liner body is impacted, the buffer component can fully absorb and buffer the impact force on the liner body through the dual buffering effect of gas compression and spring deformation, avoiding cracks caused by rigid collisions, thereby preventing local breakage or overall damage, and ensuring the protective effect of the liner body under long-term impact conditions.

[0016] By using the socket and stabilizer bar, the compressed spring can be guided when the piston plate moves, preventing the spring from twisting or bending and avoiding the spring from getting stuck between the piston plate and the piston cylinder, which would cause buffer failure. This ensures the elastic recovery performance and long-term buffering effect of the spring. The anti-collision pad prevents direct collision between the liner body and the support plate, thereby avoiding surface dents, wear or paint peeling, and extending the service life of both.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1 With appendix Figure 2As shown: A wear-resistant liner structure for mining accessories includes a mining machinery outer plate 1 and a liner body 2 disposed outside the mining machinery outer plate 1. The mining machinery outer plate 1 and the liner body 2 are connected by a flexible connecting component 3. The flexible connecting component 3 includes a set of insert frames 301 fixedly connected to one side of the mining machinery outer plate 1. Each insert frame 301 has an L-shaped insert plate 302 inserted inside, and each L-shaped insert plate 302 has a connecting frame 303 sleeved on its outside. One side of each connecting frame 303 is connected to one side of the liner body 2. The L-shaped insert plate 302 is used to connect the wear-resistant liner structure to the outer plate 1. The connection between the 2 and the insert frame 301 can form a preliminary positioning of the liner body 2, and the liner body 2 can drive the connecting frame 303 to move on the L-shaped insert plate 302. The sliding connection can effectively avoid the situation where stress concentration easily occurs in the connection part under impact load, which is prone to occur in traditional rigid connections. One side of each insert frame 301 and one side of each L-shaped insert plate 302 are threadedly connected with a set of bolts 304. The L-shaped insert plate 302 and the insert frame 301 can be fastened by the bolts 304, thereby improving the fixing effect of the liner body 2.

[0026] As attached Figure 2 As shown: Each connecting frame 303 has a set of connecting grooves 305 on both the front and back sides. Each connecting groove 305 has a connecting block 306 slidably connected to its inner wall. The ends of each set of connecting blocks 306 that are close to each other are connected to the front and back sides of the L-shaped insert plate 302 respectively. By using the cooperation between the connecting grooves 305 and the connecting blocks 306, the L-shaped insert plate 302 and the connecting frame 303 can be connected, thereby preventing the connecting frame 303 and the L-shaped insert plate 302 from separating.

[0027] As attached Figure 1 Appendix Figure 3 Appendix Figure 4 With appendix Figure 5As shown: A buffer assembly 4 is provided between the outer plate 1 and the liner body 2 of the mining machinery to absorb the impact force borne by the liner body 2. The buffer assembly 4 includes a support plate 401 disposed on one side of the liner body 2. Two sets of symmetrical piston plates 402 are fixedly connected to one side of the support plate 401. A piston cylinder 403 is piston-connected to the outside of each piston plate 402. One end of each piston cylinder 403 is connected to one side of the outer plate 1 of the mining machinery. A spring 404 is fixedly connected to one end of each piston plate 402 and the inner wall of each piston cylinder 403. When the liner body 2 is impacted by a large piece of ore during the operation of the mining machinery, the impact force is transmitted to the support plate 401 through the liner body 2. The liner body 2 will push the piston plate 402 to move inward along the axial direction of the piston cylinder 403. The compressed gas inside the piston cylinder 403 is rapidly pressurized by the piston plate 402, forming the first buffer resistance. At the same time, the piston plate 402 compresses the spring 404 synchronously when it is in position. The spring 404 can absorb the impact energy through elastic deformation. With the dual buffering effect of gas compression and spring 404 deformation, the impact force on the liner body 2 can be fully absorbed and buffered, avoiding cracks caused by rigid collisions, thereby preventing local breakage or overall damage, and ensuring the protective effect of the liner body 2 under long-term impact conditions. The other side of the support plate 401 is fixedly connected to the anti-collision pad 409. The anti-collision pad 409 can prevent direct collision between the liner body 2 and the support plate 401, thereby avoiding surface dents, wear or paint peeling, and extending the service life of both.

[0028] As attached Figure 5 As shown: Each piston plate 402 has an insertion hole 405 at one end, and a stabilizing rod 406 is slidably connected to the inner wall of each insertion hole 405. The other end of each stabilizing rod 406 is connected to the inner wall of the piston cylinder 403, and the stabilizing rod 406 is located inside the spring 404. When the piston plate 402 moves along the axial direction of the piston cylinder 403, the stabilizing rod 406 will always pass through the insertion hole 405 to guide the spring 404. This can accurately limit the compression of the spring 404, ensuring that the spring 404 always deforms along the axial direction during the compression stroke. This can effectively prevent the spring 404 from twisting or bending due to uneven impact force or lateral force, and avoid the spring 404 getting stuck between the piston plate 402 and the piston cylinder 403, which would lead to buffer failure. This ensures the elastic recovery performance and long-term buffering effect of the spring 404.

[0029] As attached Figure 4As shown: Each piston cylinder 403 has a ring of limiting frames 407 fixedly connected to its outer surface. Each limiting frame 407 has a limiting plate 408 slidably connected to its inner wall. The other end of each limiting plate 408 is connected to one side of the abutment plate 401. By using the cooperation of the limiting frame 407 and the limiting plate 408, the movement of the piston plate 402 can be limited, which can effectively prevent the piston plate 402 from detaching from the piston cylinder 403 due to excessive impact rebound force or loosening of the connection after long-term use.

[0030] Working principle: During use, the L-shaped insert plate 302 is inserted into the insert frame 301, and then the insert frame 301 and the L-shaped insert plate 302 are connected in sequence using bolts 304. This allows the liner body 2 to be stably fixed to one side of the support plate 401. When the liner body 2 is impacted by large pieces of ore during the operation of the mining machinery, the impact force is transmitted to the support plate 401 through the liner body 2. The liner body 2 will push the piston plate 402 to move inward along the axis of the piston cylinder 403. The pressure of the compressed gas inside the piston cylinder 403 will rise rapidly under the compression of the piston plate 402, forming the first buffer resistance. At the same time, when the piston plate 402 is in position, it will compress the spring 404 synchronously. The impact energy can be absorbed through the elastic deformation of the spring 404. With the dual buffering effect of gas compression and spring 404 deformation, the impact force on the liner body 2 can be fully absorbed and buffered, avoiding cracks caused by rigid collisions, thereby preventing local breakage or overall damage, and ensuring the protective effect of the liner body 2 under long-term impact conditions.
