Description

Technical Field

[0001] This application relates to the field of crusher tooth transportation technology, specifically to a clamp for lifting crusher teeth of an intelligent crusher. Background Technology

[0002] A crusher is a device that applies mechanical force to solid materials to overcome their cohesive forces and break them into smaller pieces. With the continuous development and progress of technology, crushers are gradually becoming more intelligent. Common crushers include jaw crushers, cone crushers, gyratory crushers, hammer crushers, and roller crushers. Among them, the crushing teeth of the roller crusher are shaped like rollers, hence the name. Due to their large size, the crushing teeth are usually hoisted during transportation. Existing hoisting methods typically use steel wire ropes to tie the crushing teeth, which is not only inconvenient to operate but also has poor safety. Therefore, an intelligent clamp for hoisting crushing teeth of a crusher is proposed. Summary of the Invention

[0003] The purpose of this application is to solve the technical problem that the existing hoisting method usually uses steel wire rope to tie the crusher teeth, which is not only inconvenient to operate, but also has poor safety. This application provides a smart clamp for hoisting crusher teeth.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution:

[0005] A clamp for lifting the crusher teeth of an intelligent crusher includes:

[0006] Two fixed frames are symmetrically distributed and located at both ends of the crushing tooth. Each fixed frame is equipped with a clamping mechanism and two fixed rods, both L-shaped and symmetrically distributed. The clamping mechanism clamps or releases the crushing tooth. Each fixed rod is equipped with a lifting ring. The two fixed rods on the same side are fixed or released by a connector.

[0007] Furthermore, the clamping mechanism includes a plurality of clamping rods that are slidably disposed on the fixed frame and distributed in a circular array. The free end of each clamping rod is provided with an arc-shaped block that abuts and overlaps with the crushing teeth. The fixed frame is rotatably provided with a lead screw that is the same number as the clamping rods and is threadedly engaged with them one by one.

[0008] Furthermore, a bevel gear ring is rotatably mounted on the fixed frame, and a bevel gear that meshes with the bevel gear ring is mounted on the lead screw.

[0009] Furthermore, the fixing frame is provided with a fixing cylinder and an extension rod, and the free end of the extension rod is provided with a positioning plate that abuts and overlaps with the crushing teeth.

[0010] Furthermore, the fixing rod includes an outer rod that is mounted on the fixing frame and has an L-shaped structure. An inner rod is slidably mounted on the outer rod, and a locking member is mounted on both of them. The inner rod is locked by the locking member, and the two inner rods located on the same side are fixed or unfixed by a connecting member.

[0011] Furthermore, the outer rod is slidably mounted on the fixed frame, and the fixed frame and the two outer rods are provided with driving components, which drive the two outer rods to slide synchronously in opposite directions.

[0012] Furthermore, the driving component includes a screw rotatably mounted on a fixed frame, a drive motor with an output shaft connected to the screw mounted on the fixed frame, a slider threadedly mounted on the fixed frame and threadedly engaged with the screw, and two drive rods symmetrically hinged on the slider, with the free ends of the two drive rods respectively hinged to two outer rods.

[0013] Furthermore, the locking component includes a connecting plate disposed on the outer rod, a plurality of locking holes arrayed on the inner rod, a locking rod slidably disposed on the connecting plate and inserted into the locking holes, a limit block disposed at the free end of the locking rod, and a tension spring sleeved on the locking rod disposed between the limit block and the connecting plate.

[0014] Furthermore, one of the inner rods is provided with a positioning groove, and the other inner rod is provided with a positioning block that engages with the positioning groove.

[0015] Furthermore, the connector includes a U-bolt, the two free ends of which pass through two adjacent locking holes and are threaded with fastening nuts that abut against and overlap the inner rod.

[0016] The beneficial effects of this application are as follows:

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown in one embodiment of this application, a clamp for lifting the crushing teeth of an intelligent crusher is provided for clamping the crushing teeth 1, comprising:

[0028] Two fixed frames 2 are symmetrically distributed and located at both ends of the crushing tooth 1. The crushing tooth 1 is roller-shaped and horizontal. The fixed frame 2 is equipped with a clamping mechanism 3 and two fixed rods 4, both L-shaped and symmetrically distributed. The fixed rods 4 are horizontal and clamp or release the crushing tooth 1 through the clamping mechanism 3. The fixed rods 4 are equipped with lifting rings 5, which are vertical and fixed to the fixed rods 4. The two fixed rods 4 on the same side are fixed or released through a connector 6.

[0029] When hoisting the crusher 1, the crusher 1 is in a horizontal position. The two fixing frames 2 are located at both ends of the crusher 1, and the fixing rods 4 are kept in a horizontal position. The two fixing rods 4 on the same side are fixed by the connector 6. The two ends of the crusher 1 are clamped by the two clamping mechanisms 3. Then, the hoisting hook is hooked onto the lifting ring 5, and the crusher 1 can be hoisted. Conversely, after the crusher 1 is transported to the required position, the two fixing rods 4 on the same side are released from the fixing by the connector 6. The two ends of the crusher 1 are released from the fixing by the two clamping mechanisms 3. Finally, the two fixing frames 2 are moved away from the two ends of the crusher 1.

[0030] In summary, this application abandons the conventional method of binding the crushing tooth 1 with steel wire rope. In use, two fixing frames 2 are placed at both ends of the crushing tooth 1, and the fixing rod 4 is kept horizontal. The two fixing rods 4 on the same side are fixed by the connector 6. The two ends of the crushing tooth 1 are clamped by two clamping mechanisms 3. Then, the lifting hook is hooked onto the lifting ring 5, and the crushing tooth 1 can be lifted. The operation is convenient and the safety is improved, so it is more practical.

[0031] like Figure 2 As shown, in some embodiments, the clamping mechanism 3 includes a plurality of clamping rods 301 that are slidably disposed on the fixed frame 2 and distributed in a ring array. The free end of the clamping rod 301 is provided with an arc-shaped block 302 that abuts against and overlaps with the crushing tooth 1. The arc-shaped block 302 is fixedly connected to the clamping rod 301. The fixed frame 2 is rotatably provided with the same number of screws 303 as the clamping rods 301 and threadedly engaged with each other. The plurality of screws 303 are distributed in a ring array.

[0032] Referring to the above, in the initial state, the multiple clamping rods 301 are far apart from each other. During use, the multiple lead screws 303 are driven to rotate synchronously in the positive direction. The multiple clamping rods 301 slide synchronously towards each other due to the thread action until the multiple arc-shaped blocks 302 all abut against and overlap with the crushing tooth 1, so as to clamp the crushing tooth 1. Conversely, the multiple lead screws 303 are driven to rotate synchronously in the opposite direction. The multiple clamping rods 301 slide synchronously away from each other due to the thread action until the multiple arc-shaped blocks 302 are far away from the crushing tooth 1, so as to release the crushing tooth 1 from clamping.

[0033] like Figure 2 As shown, in some embodiments, a bevel gear ring 304 is rotatably mounted on the fixed frame 2, the bevel gear ring 304 is in a vertical direction, and a bevel gear 305 that meshes with the bevel gear ring 304 is mounted on the lead screw 303, the bevel gear 305 is fixed on the lead screw 303;

[0034] Referring to the above, when in use, driving the bevel gear ring 304 to rotate in the forward direction will cause multiple bevel gears 305 to rotate together due to meshing, thereby achieving synchronous forward rotation of multiple lead screws 303. Conversely, driving the bevel gear ring 304 to rotate in the reverse direction will cause multiple bevel gears 305 to rotate together due to meshing, thereby achieving synchronous reverse rotation of multiple lead screws 303.

[0035] like Figure 2 As shown, in some embodiments, a fixing cylinder 7 and an extension rod 8 are provided on the fixing frame 2. Both the fixing cylinder 7 and the extension rod 8 are horizontal and fixed on the fixing frame 2. The free end of the extension rod 8 is provided with a positioning plate 9 that abuts against and overlaps with the crushing tooth 1. The positioning plate 9 is fixedly connected to the extension rod 8.

[0036] Referring to the above, during use, the two fixed frames 2 are positioned at both ends of the crushing tooth 1, and the two ends of the crushing tooth 1 enter the two fixed cylinders 7 respectively and abut against the two fixed frames 2 respectively. The two positioning plates 9 abut against the two ends of the crushing tooth 1 respectively. This design can not only achieve quick positioning of the fixed frames 2, but also facilitate the placement operation after the crushing tooth 1 is transported to the required position.

[0037] like Figures 3-6 As shown, in some embodiments, the fixing rod 4 includes an outer rod 401 that is arranged on the fixing frame 2 and has an L-shaped structure. The outer rod 401 is horizontal. An inner rod 402 is slidably arranged on the outer rod 401 and a locking member 10 is arranged on both of them. The inner rod 402 is horizontal and slides in the horizontal direction. The inner rod 402 is locked by the locking member 10. The two inner rods 402 located on the same side are fixed or unfixed by the connecting member 6.

[0038] Referring to the above, in the initial state, the inner rod 402 retracts into the outer rod 401 and is locked by the locking member 10, preventing the inner rod 402 from sliding. At this time, the overall space occupied by the fixing rod 4 is small. In use, the inner rod 402 is unlocked by the locking member 10, allowing the inner rod 402 to slide horizontally. The sliding distance depends on the specific length of the crushing tooth 1 until the two inner rods 402 on the same side abut and overlap. The two inner rods 402 are then fixed by the connecting member 6 and locked by the two locking members 10 respectively. Conversely, the two inner rods 402 are unfixed by the connecting member 6 and unlocked by the two locking members 10 respectively, allowing the inner rod 402 to retract into the outer rod 401 and relocked by the locking member 10. This design not only reduces the space occupied when not in use but also adapts to crushing teeth 1 of different lengths, thereby improving the flexibility and adaptability of use.

[0039] like Figure 1As shown, in some embodiments, the outer rod 401 is slidably mounted on the fixed frame 2, and the fixed frame 2 and the two outer rods 401 are provided with driving members 11, which drive the two outer rods 401 to slide synchronously in opposite directions.

[0040] Referring to the above, in the initial state, the two outer rods 401 are close to each other, and the overall space occupied by the fixed rod 4 is small. When in use, the two outer rods 401 are driven to slide synchronously in opposite directions to move away from each other by the driving component 11 until the distance between the two inner rods 402 is greater than the diameter of the crushing tooth 1, and then the subsequent operation is carried out. Conversely, when not in use, the two outer rods 401 are driven to slide synchronously in opposite directions to move closer to each other by the driving component 11. This design can not only reduce the space occupied when not in use, but also adapt to crushing teeth 1 of different diameters, thereby improving the flexibility and adaptability of use.

[0041] like Figure 3 As shown, in some embodiments, the driving component 11 includes a screw 1101 rotatably mounted on the fixed frame 2, the screw 1101 being in a horizontal direction, a drive motor 1102 with its output shaft connected to the screw 1101 being mounted on the fixed frame 2, the drive motor 1102 being fixedly mounted on the fixed frame 2 and its output shaft being fixedly connected to the screw 1101, a slider 1103 being slidably mounted on the fixed frame 2 and threadedly engaged with the screw 1101, the slider 1103 sliding in a horizontal direction, and two drive rods 1104 being symmetrically hinged on the slider 1103, the free ends of the two drive rods 1104 being respectively hinged to two outer rods 401;

[0042] Referring to the above, in the initial state, slider 1103 is close to drive motor 1102, and drive rod 1104 and screw 1101 tend to be parallel. At this time, the two outer rods 401 are close to each other. When in use, drive motor 1102 is turned on, drive motor 1102 works, output shaft rotates forward, driving screw 1101 to rotate together. Slider 1103 will slide horizontally away from drive motor 1102 due to the thread action. Drive rod 1104 rotates around the hinge point. Drive rod 1104 and screw 1101 tend to be perpendicular. The two outer rods 401 slide synchronously in opposite directions to move away from each other. Conversely, the output shaft of drive motor 1102 is reversed, driving screw 1101 to rotate together. Slider 1103 will slide horizontally close to drive motor 1102 due to the thread action. Drive rod 1104 rotates around the hinge point. Drive rod 1104 and screw 1101 tend to be parallel. The two outer rods 401 slide synchronously in opposite directions to move closer to each other.

[0043] like Figures 4-6As shown, in some embodiments, the locking member 10 includes a connecting plate 1001 disposed on the outer rod 401. The connecting plate 1001 is fixedly disposed on the outer rod 401. A plurality of locking holes 1002 are arranged in an array on the inner rod 402. The locking holes 1002 are vertical and the plurality of locking holes 1002 are arranged in an array in a horizontal direction. A locking rod 1003 is slidably disposed on the connecting plate 1001 and is inserted into the locking holes 1002. The locking rod 1003 is vertical and slides in a vertical direction. A limit block 1004 is disposed at the free end of the locking rod 1003. The limit block 1004 is fixedly connected to the locking rod 1003 and forms a stepped structure. A tension spring 1005 is disposed between the limit block 1004 and the connecting plate 1001 and is sleeved on the locking rod 1003. The tension spring 1005 is vertical and its two ends are fixedly connected to the limit block 1004 and the connecting plate 1001, respectively.

[0044] Referring to the above, in the initial state, the tension spring 1005 is in its natural state, the limit block 1004 is close to the connecting plate 1001, and the locking rod 1003 is inserted into one of the locking holes 1002. At this time, due to the obstruction of the locking rod 1003, the inner rod 402 cannot slide horizontally, thus locking the inner rod 402. In use, the limit block 1004 is pulled away from the connecting plate 1001, causing the locking rod 1003 to slide vertically until it exits the locking hole 1002. The tension spring 1005 is stretched, and at this time, due to the removal of the obstruction of the locking rod 1003, The inner rod 402 can slide horizontally to unlock it. When two inner rods 402 on the same side collide, the limiting block 1004 is released, and the tension spring 1005 returns to its natural state due to being stretched. The limiting block 1004 and the locking rod 1003 move downward together due to elastic potential energy. The limiting block 1004 approaches the connecting plate 1001, and the locking rod 1003 is inserted into one of the locking holes 1002. At this time, due to the obstruction of the locking rod 1003, the inner rod 402 cannot slide horizontally, thus locking it.

[0045] like Figure 6 As shown, in some embodiments, one inner rod 402 is provided with a positioning groove 12, and the other inner rod 402 is provided with a positioning block 13 that is inserted into and cooperates with the positioning groove 12. The positioning block 13 is fixedly connected to the inner rod 402.

[0046] Referring to the above, in the initial state, the positioning block 13 is far away from the positioning groove 12. When the two inner rods 402 on the same side abut and overlap, the positioning block 13 is inserted into the positioning groove 12. This not only enables rapid positioning between the two inner rods 402, but also improves the connection strength between them, thereby improving the stability of use.

[0047] like Figure 6As shown, in some embodiments, the connector 6 includes a U-bolt 601, the two free ends of which pass through two adjacent locking holes 1002 and are threaded with fastening nuts 602 that abut against and overlap with the inner rod 402.

[0048] Referring to the above, in the initial state, both fastening nuts 602 are separated from the U-bolt 601. When the two inner rods 402 on the same side abut and overlap, the two free ends of the U-bolt 601 pass through the two adjacent locking holes 1002 respectively. Then, tighten the two fastening nuts 602 to both ends of the U-bolt 601 until the fastening nuts 602 abut and overlap with the inner rods 402, thus fixing the two inner rods 402. Conversely, loosen the two fastening nuts 602 to disengage from the U-bolt 601, so that the free ends of the U-bolt 601 exit the two adjacent locking holes 1002 respectively, thus achieving contact and fixing of the two inner rods 402.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
