Description

Technical Field

[0001] The present invention relates to the technical field of cone crushers, and more particularly to a filling ring structure of a cone crusher. Background Art

[0002] A cone crusher is a type of mining machinery used for crushing stone. Its working principle is as follows: The crushing chamber is formed between the moving cone and the fixed cone inside the cone crusher. The eccentrically rotating moving cone and the fixed cone squeeze and crush the stone. Therefore, the fixed cone is a crucial component of the crushing chamber.

[0003] In existing cone crushers, epoxy resin is typically placed between the fixed cone and the upper frame to fill the gap between the upper frame and the fixed cone. While this structure provides good sealing performance and ensures more uniform stress distribution across the entire structure, repairing and maintaining the fixed cone can damage the epoxy resin filling material. Subsequently, when the fixed cone is reinstalled, the epoxy resin inside must be cleaned and refilled with new epoxy resin. This process takes at least 10 hours from pouring to drying, requiring the cone crusher to be shut down during this time, severely impacting operating efficiency. This process increases the cost of repairing, maintaining, and replacing the fixed cone.

[0004] For example, the Chinese patent publication number CN219994220U, the publication date of November 11, 2022, is titled "A cone crusher fixed cone liner support structure diagram". In this application, epoxy resin filler is directly set between the fixed cone liner and the upper frame, so that the gap between the fixed cone liner and the upper frame is filled; this significantly increases the cost of repairing and maintaining the fixed cone. Summary of the Invention

[0005] The present invention overcomes the problem in the prior art that epoxy resin is filled between the fixed cone and the upper frame, which makes the repair, maintenance and replacement costs of the fixed cone too high when the fixed cone is maintained. A filling ring structure of a cone crusher is provided, which can replace the filled epoxy resin with a filling ring structure, making it convenient to inspect, maintain and replace the positioning body, and effectively reducing the repair, maintenance and replacement costs of the fixed cone.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a filling ring structure of a cone crusher, comprising: an upper frame and a fixed cone, the fixed cone is arranged in the upper frame, the outer wall of the fixed cone is abutted with the filling ring in the circumferential direction, a plurality of positioning members are penetrated through the side wall of the upper frame in the circumferential direction, the end of the positioning member abuts against the outer wall of the filling ring, and an auxiliary abutting sleeve is sleeved on the positioning member.

[0007] In the present invention, by arranging the filling ring and the positioning member to cooperate, the positioning member can abut against the filling ring, so that the fixed cone can be positioned and fixed. When the fixed cone needs to be inspected and maintained, the positioning member can be removed by rotating the positioning member, and then the fixed cone and the filling ring can be easily removed, which facilitates the inspection and maintenance of the positioning cone. In addition, since the dynamic cone of the cone crusher is in motion, the faster the dynamic cone rotates, the greater the impact force of the fixed cone will be. When the power of the cone crusher increases to a certain level, the impact force on the positioning member will also increase, which can easily cause the positioning member to deform. Therefore, an auxiliary abutment sleeve is provided in the circumferential direction of the positioning member to protect the positioning member.

[0008] Preferably, an abutting convex ring is provided on the circumferential direction of the outer side wall of the fixed cone, and an L-shaped annular groove is provided on the filling ring, and the L-shaped annular groove cooperates with the abutting convex ring.

[0009] The L-shaped ring groove cooperates with the abutting convex ring, so that the filling ring can better cooperate with the abutting convex ring.

[0010] Preferably, the auxiliary abutment sleeve includes a fixed ring sleeve and a sliding ring sleeve; an annular inner cavity is provided in the fixed ring sleeve, and a fixed ring groove is provided on the end face of one end of the inner cavity; the sliding ring sleeve includes an outer end ring abutting against the outer side wall of the filling ring, an inner end ring provided in the inner cavity, and a sliding ring plate connecting the outer end ring and the inner end ring, and the sliding ring plate is slidably provided in the fixed ring groove; a plurality of reset springs are abutted between the end of the inner cavity away from the fixed ring groove and the inner end ring; the inner cavity is filled with a non-Newtonian fluid; a plurality of first elastic bags connected to the inner cavity are provided in the circumferential direction of the outer wall of the fixed ring sleeve.

[0011] When the power of the cone crusher reaches a certain level, the dynamic cone exerts a greater instantaneous impact force on the fixed cone after acting on the ore, causing the fixed cone to be subjected to a greater impact force. The fixed cone transmits this impact force to the sliding ring through the filling ring. Because the inner end ring of the sliding ring is located in the inner cavity, which contains a non-Newtonian fluid, when the large impact acts on the non-Newtonian fluid through the inner end ring, the non-Newtonian fluid is very rigid, thus supporting the sliding ring, allowing the sliding ring to support the filling ring, sharing the force on the locating bolts, thereby reducing the force on the locating bolts and protecting them. When the power of the cone crusher is at a lower level, the non-Newtonian fluid is less rigid, allowing the inner end ring to move within the inner cavity, providing a buffer and vibration reduction effect for the fixed cone. In addition, the provision of the first elastic bladder ensures that the inner cavity is always filled with non-Newtonian fluid, which effectively protects the locating bolts when the fixed cone is subjected to sudden impact forces.

[0012] Preferably, an annular abutment platform is provided on the inner side wall of the upper frame, and the annular abutment platform is provided on the upper end surface of the filling ring; an auxiliary abutment device abuts between the upper end surface of the filling ring and the annular abutment platform.

[0013] By providing the auxiliary abutment, the upward component of the impact force can be supported.

[0014] Preferably, the auxiliary abutment includes a fixed sleeve and a sliding rod, a fixed hole is provided at the end of the fixed sleeve, and the sliding rod passes through the fixed hole and is slidably arranged in the fixed sleeve; a thrust spring is abutted between the end of the fixed sleeve away from the fixed hole and the end of the sliding rod; a second elastic bag is provided on the side wall of the fixed sleeve, and the second elastic bag and the fixed sleeve are connected to each other; a non-cow fluid is provided in the fixed sleeve.

[0015] When the power of the cone crusher increases to a certain level, the instantaneous impact force is very large. When the sliding rod receives a large impact force, the non-Newtonian fluid at this time shows a very large stiffness, which can effectively withstand the impact. When the power of the cone crusher decreases to a certain level, the impact force on the sliding rod is small, and the non-Newtonian fluid has a small stiffness, which can play a role in buffering and vibration reduction.

[0016] Preferably, the fixing ring is embedded on the inner wall of the upper frame.

[0017] Through the above arrangement, the fixing ring can be firmly abutted against the upper frame.

[0018] Preferably, the positioning member is a positioning bolt, a threaded hole is provided through the side wall of the upper frame, and the positioning bolt is threadedly connected to the threaded hole.

[0019] By arranging the positioning piece as a positioning bolt, the disassembly and assembly of the filling ring can be facilitated.

[0020] Preferably, eight positioning bolts are provided, and the eight positioning bolts are evenly arranged along the circumferential direction of the upper frame.

[0021] There are eight positioning bolts so that they can respectively abut the filling ring in eight directions, making the fixed cone more stable when it is arranged in the upper frame.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The setting of the positioning bolts makes it easy to inspect, maintain and replace the positioning body, effectively reducing the cost of repair, maintenance and replacement of the fixed cone;

[0024] (2) By setting up an auxiliary abutment sleeve, it can protect the positioning bolts and at the same time play a role in buffering and reducing vibration when the cone crusher rotates at low power. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0030] Example 1: Reference Figures 1 to 3 As shown, a filling ring structure for a cone crusher comprises an upper frame 1 and a fixed cone 2. The fixed cone 2 is disposed within the upper frame 1. An abutting protrusion 21 is integrally formed on the circumferential outer wall of the fixed cone 2. An L-shaped annular groove 31 is provided on the filling ring 33, which cooperates with the abutting protrusion 21. Several positioning members 4 are provided through the circumferential sidewall of the upper frame 1. The ends of the positioning members 4 abut the outer wall of the filling ring 3. Auxiliary abutting sleeves 5 are sleeved on the positioning members 4.

[0031] The positioning member 4 in this embodiment is a positioning bolt, and there are eight positioning bolts, which are evenly arranged along the circumferential direction of the upper frame body 1; a threaded hole 11 is provided through the side wall of the upper frame body 1, and the positioning bolt is threadedly connected to the threaded hole 11, and the end of the positioning bolt abuts against the outer wall of the filling ring 3.

[0032] The auxiliary abutment sleeve 5 includes a fixed ring sleeve 51, a sliding ring sleeve 52 and a plurality of return springs 53; the fixed ring sleeve 51 is inlaid on the inner side wall of the upper frame body 1, and an annular inner cavity 54 is provided in the fixed ring sleeve 51, and a fixed ring groove 511 is provided on the end surface of one end of the inner cavity 54; the sliding ring sleeve 52 includes an outer end ring 521, an inner end ring 523 and a sliding ring plate 522, the outer end ring 521 abuts against the outer side wall of the filling ring 3, the inner end ring 523 is provided in the inner cavity 54, and the two ends of the sliding ring plate 522 are fixedly connected to the outer end ring 521 and the inner end ring 523, the sliding ring plate 522 is slidably arranged in the fixed ring groove 511; a plurality of return springs 53 are abutted between the end of the inner cavity 54 away from the fixed ring groove 511 and the inner end ring 523. In this embodiment, six return springs 53 are provided, and the six return springs 53 are evenly arranged along the circumferential direction of the fixed ring sleeve 51; a plurality of first elastic bags 55 connected to the inner cavity 54 are provided in the circumferential direction of the outer wall of the fixed ring sleeve 51, and the first elastic bags 55 are made of rubber material. The first elastic bags 55 and the inner cavity 54 are filled with non-Newtonian fluid.

[0033] The working principle of the present invention is as follows: In the present invention, by arranging the filling ring 3 and the positioning bolt to cooperate, the positioning bolt can abut on the filling ring 3, so that the fixed cone 2 can be positioned and fixed. When the fixed cone 2 needs to be inspected and maintained, the positioning bolt can be removed by rotating the positioning bolt, and then the fixed cone 2 and the filling ring 3 can be easily removed, which facilitates the inspection and maintenance of the positioning cone.

[0034] In addition, as the moving cone of the cone crusher moves, the faster the moving cone rotates, the greater the impact force on the fixed cone 2 will be. When the power of the cone crusher increases to a certain level, the impact force on the positioning bolt will also be greater, which can easily cause the positioning bolt to deform. Therefore, an auxiliary abutment sleeve 5 is provided in the circumferential direction of the positioning bolt.

[0035] The working principle of the auxiliary abutment sleeve 5 is as follows: when the power of the cone crusher increases to a certain level, the instantaneous impact force of the dynamic cone on the fixed cone 2 after acting on the ore is relatively large, so that the fixed cone 2 is subjected to a large impact force. The fixed cone 2 transmits the impact force to the sliding ring sleeve 52 through the filling ring 3. Since the inner end ring 523 of the sliding ring sleeve 52 is arranged in the inner cavity 54, a non-Newtonian fluid is arranged in the inner cavity 54. When a large impact acts on the non-Newtonian fluid through the inner end ring 523, the stiffness of the non-Newtonian fluid at this time is very large, thereby supporting the sliding ring sleeve 52, so that the sliding ring sleeve 52 can be supported on the filling ring 3, and can share the force of the positioning bolts, thereby reducing the force of the positioning bolts and protecting the positioning bolts; and when the power of the cone crusher is at a low level, the stiffness of the non-Newtonian fluid at this time is relatively small, so that the inner end ring 523 can move in the inner cavity 54, playing a role in buffering and reducing vibration of the fixed cone. In addition, the provision of the first elastic bag 55 in this embodiment enables the inner cavity 54 to always be filled with non-Newtonian fluid, so that when the fixed cone 2 is subjected to a sudden impact force, it can also provide good protection for the positioning bolts.

[0036] Example 2: Reference Figures 1 to 3 As shown, this embodiment is similar in structure to embodiment 1, except that an annular abutment platform 12 is fixedly provided on the inner wall of the upper frame 1, and the annular abutment platform 12 is provided above the upper end surface of the filling ring 3; an auxiliary abutment device 6 is abutted between the upper end surface of the filling ring 3 and the annular abutment platform 12. The number and position of the auxiliary abutments 6 correspond to those of the auxiliary abutment sleeve 5. The auxiliary abutment 6 includes a fixed sleeve 61 and a sliding rod 62. A fixing hole 611 is provided at the end of the fixed sleeve 61. The sliding rod 62 passes through the fixing hole 611 and is slidably arranged in the fixed sleeve 61. The end of the fixed sleeve 61 away from the fixing hole 611 is fixedly arranged on the annular abutment platform 12, and the end of the sliding rod 62 away from the fixed sleeve 61 abuts against the upper end surface of the filling ring 3; a thrust spring 63 abuts between the end of the fixed sleeve 61 away from the fixing hole 611 and the end of the sliding rod 62, and the thrust spring 63 pushes the sliding rod 62 to move in the direction away from the fixed sleeve 61; a second elastic bag 64 is provided on the side wall of the fixed sleeve 61, and the second elastic bag 64 and the fixed sleeve 61 are connected to each other; the second elastic bag 64 is made of rubber material, and non-Newtonian fluid is provided in the fixed sleeve 61 and the second elastic bag 64. The second elastic bag 64 is provided so that the non-Newtonian fluid in the fixed sleeve 61 can be kept full.

[0037] In this embodiment, since the impact force is usually in an inclined direction when the fixed cone 2 acts on the moving cone, the auxiliary abutment 6 is provided to offset the upward component of the impact force; and when the power of the cone crusher increases to a certain level, the instantaneous impact force is very large, so that when the sliding rod 62 receives a large impact force, the non-Newtonian fluid at this time exhibits a very large stiffness, which can effectively withstand the impact; and when the power of the cone crusher is reduced to a certain level, the impact force on the sliding rod 62 is small, and the non-Newtonian fluid has a small stiffness, which can play a role in buffering and vibration reduction.

[0038] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
