Description

Technical Field

[0001] This utility model relates to a cone crusher, and more particularly to a fixed cone locking device for a cone crusher. Background Technology

[0002] Cone crushers are a type of secondary or tertiary crushing equipment widely used in industries such as mining, metallurgy, and building materials. They are mainly used for crushing medium-hard and harder materials such as granite, basalt, and iron ore. During crushing, the material enters the crushing chamber from the top feed inlet and falls between the moving cone and the fixed cone. Driven by the eccentric sleeve, the moving cone makes a gyratory motion, continuously squeezing the material between the moving cone and the fixed cone, thereby crushing the material.

[0003] Existing cone crushers typically have a locking ring above the fixed cone that is threaded with the fixed cone for locking. The locking ring is tightened or loosened by raising and lowering a hydraulic telescopic rod. When the hydraulic telescopic rod stops due to a malfunction, it tends to retract, causing the locking ring to loosen from the fixed cone, resulting in poor stability of the fixed cone. Summary of the Invention

[0004] The purpose of this invention is to provide a fixed and stable cone crusher locking device to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fixed cone locking device for a cone crusher is provided, comprising a frame, a fixed cone placed inside the frame, a fixed cylinder fixedly connected to the outside of the frame, a tightening mechanism fixedly connected to the top and bottom of the fixed cylinder near the frame, and a limiting mechanism fixedly connected to the top and bottom of the fixed cylinder away from the frame. The limiting mechanism includes a connecting cylinder fixedly connected to the top and bottom of the side away from the frame, a stud threaded inside the connecting cylinder, a screw block fixedly connected to the end of the stud away from the connecting cylinder, a washer placed outside the stud, a lifting plate movably connected inside the connecting cylinder, a rubber pad fixedly connected to the side of the lifting plate near the screw block, a second spring fixedly connected between the rubber pad and the connecting cylinder, and a limiting post fixedly connected to the side of the lifting plate away from the rubber pad.

[0006] Optionally, the frame includes a frame body, the outer side of which is provided with insertion holes, and the lower part of which is provided with fixing holes.

[0007] Optionally, the fixed cone includes an outer cylinder placed inside the frame, a slot on the outer side of the outer cylinder, a reinforcing plate fixedly connected to the inner side of the outer cylinder, a lifting hole inside the reinforcing plate, a liner fixedly connected to the inner side of the reinforcing plate, and an alignment block fixedly connected to the top of the outer cylinder.

[0008] Optionally, the fixed cylinder includes a cylinder body fixedly connected to the outside of the frame. The cylinder body has a through hole inside. An insert plate is movably connected inside the cylinder body. Limit strips are fixedly connected to both the front and rear sides of the insert plate. A connecting column is fixedly connected to the side of the insert plate away from the frame. A connecting plate is fixedly connected to the top and bottom of the connecting column away from the insert plate. A guide column is fixedly connected to the side of the connecting plate near the insert plate. Fixed plates are fixedly connected to the upper and lower sides of the inner side of the cylinder. A first spring is fixedly connected between the connecting plate and the fixed plate. A limit plate is fixedly connected to the side of the fixed plate near the connecting plate.

[0009] Optionally, the clamping mechanism includes a hydraulic telescopic rod fixedly connected to the top and bottom of the cylinder near the frame, and a top block is fixedly connected to one end of the hydraulic telescopic rod near the insert plate.

[0010] Optionally, the length of the stud is equal to the length between the rubber pad and the screw block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention improves the stability of the fixed cone by setting a limiting mechanism. In use, the fixed cone is first installed and then lifted through the lifting hole. Lifting the fixed cone positions it inside the frame. Activating the tightening mechanism allows the top block to push the insert plate into the slot, thus fixing the fixed cone. After the insert plate is inserted into the slot, the distance from the left side of the connecting column to the inner wall of the cylinder matches the length of the limiting column. Under the elastic force of the second spring, the limiting column can be inserted into the through hole, ensuring a close fit between the limiting column and the connecting column. This limits the position of the connecting column, ensuring that the insert plate will not disengage from the slot in the event of a malfunction causing the top block to retract, thus making the fixed cone more securely fixed. By turning the screw block, the stud rotates inside the connecting cylinder, and the forward and reverse rotation of the stud causes it to rise and fall inside the connecting cylinder, causing the inner end of the stud to press against the rubber pad, thereby limiting the position of the limiting column and preventing it from being released from the limiting position of the connecting column due to vibrations generated by the operation of the crusher, further ensuring the stability of the fixation.

[0023] Reference Figures 1 to 4 The present invention will now be described. The cone crusher fixed cone locking device includes a frame 1, a fixed cone 2 placed inside the frame 1, a fixed cylinder 3 fixedly connected to the outside of the frame 1, a tightening mechanism 5 fixedly connected to the top and bottom of the fixed cylinder 3 near the frame 1, and a limiting mechanism 4 fixedly connected to the top and bottom of the fixed cylinder 3 away from the frame 1. The limiting mechanism 4 includes a connecting cylinder 401 fixedly connected to the top and bottom of the side away from the frame 1, a stud 408 threadedly connected inside the connecting cylinder 401, a screw block 402 fixedly connected to the end of the stud 408 away from the connecting cylinder 401, and a locking block 402 placed on the outside of the stud 408. A washer 403 is provided to ensure the stability of the stud 408 after tightening and to prevent the stud 408 from loosening. A lifting plate 407 is movably connected inside the connecting cylinder 401. The lifting plate 407 can be raised and lowered inside the connecting cylinder 401. A rubber pad 405 is fixedly connected to the side of the lifting plate 407 near the tightening block 402. A second spring 404 is fixedly connected between the rubber pad 405 and the connecting cylinder 401. A limit post 406 is fixedly connected to the side of the lifting plate 407 away from the rubber pad 405. In use, the fixed cone 2 is installed first, and the fixed cone 2 can be lifted through the lifting hole 204. The fixed cone 2 is lifted so that it is located inside the frame 1. By activating the clamping mechanism 5, the top block 502 can push the insert plate 308 into the slot 202, thereby fixing the fixed cone 2. After the insert plate 308 is inserted into the slot 202, the distance from the left side of the connecting column 307 to the inner wall of the cylinder 301 matches the length of the limiting column 406. Under the elastic force of the second spring 404, the limiting column 406 can be inserted into the through hole 302, and the limiting column 406 is in contact with the connecting column 307, thereby limiting the connecting column 307 and ensuring that the hydraulic telescopic rod 501 is in place due to any reason. In the event of a machine malfunction causing the top block 502 to retract, the insert plate 308 will not disengage from the slot 202, thus making the fixed cone 2 more securely fixed. By turning the screw block 402, the stud 408 rotates inside the connecting cylinder 401. The forward and reverse rotation of the stud 408 causes it to rise and fall inside the connecting cylinder 401, thereby pressing the inner end of the stud 408 onto the rubber pad 405, which in turn limits the limit post 406, preventing the limit post 406 from releasing the limit on the connecting post 307 due to vibrations generated during the operation of the crusher, further ensuring the stability of the fixation.

[0024] In another embodiment of the present invention, the frame 1 includes a frame body 101, and the outer side of the frame body 101 is provided with an insertion hole 102 for the insertion plate 308 and the limiting strip 309 to pass through. The lower part of the frame body 101 is provided with a fixing hole 103, through which the frame body 101 can be fixed to the outer shell of the transmission components such as the main shaft and eccentric sleeve of the cone crusher.

[0025] In another embodiment of this utility model, the fixed cone 2 includes an outer cylinder 201 placed inside the frame 101. The outer side of the outer cylinder 201 is provided with a slot 202 for inserting the insertion plate 308. A reinforcing plate 203 is fixedly connected to the inner side of the outer cylinder 201. A lifting hole 204 is provided inside the reinforcing plate 203. The lifting hole 204 facilitates the hoisting of the fixed cone 2. A liner 205 is fixedly connected to the inner side of the reinforcing plate 203. An alignment block 206 is fixedly connected to the top of the outer cylinder 201. The alignment block 206 is used to align the fixed cone 2 with the frame 1. The frame 101 is provided with a slot corresponding to the alignment block 206. By inserting the alignment block 206 into the corresponding slot, the insertion hole 102 corresponds to the slot 202, so that the insertion plate 308 can be inserted into the slot 202.

[0026] In another embodiment of this utility model, the fixing cylinder 3 includes a cylinder 301 fixedly connected to the outside of the frame 101. The cylinder 301 has a through hole 302 for inserting the limiting post 406. An insert plate 308 is movably connected inside the cylinder 301. Limiting strips 309 are fixedly connected to both the front and rear sides of the insert plate 308 to ensure the stability of the insert plate 308's movement. A connecting post 307 is fixedly connected to the side of the insert plate 308 away from the frame 101. Connecting plates 303 are fixedly connected to the top and bottom of the connecting post 307 on the side away from the insert plate 308. A guide is fixedly connected to the side of the connecting plate 303 closest to the insert plate 308. A fixing plate 305 is fixedly connected to the upper and lower sides of the inner side of the guide column 306 and the cylinder 301. The fixing plate 305 can move outside the guide column 306. A first spring 304 is fixedly connected between the connecting plate 303 and the fixing plate 305. A limit plate 310 is fixedly connected to the side of the fixing plate 305 near the connecting plate 303. The limit plate 310 is used to prevent the connecting plate 303 from excessively compressing the first spring 304. The top and bottom of the insert plate 308 near the connecting column 307 are set at an angle. By activating the hydraulic telescopic rod 501, the top block 502 can push the insert plate 308 to insert into the slot 202, thereby fixing the fixed cone 2.

[0027] In another embodiment of this utility model, the clamping mechanism 5 includes a hydraulic telescopic rod 501 fixedly connected to the top and bottom of the cylinder 301 near the frame 101. The hydraulic telescopic rod 501 is powered by a hydraulic pump, which can convert hydraulic energy into mechanical linear motion, so that the hydraulic telescopic rod 501 can drive the top block 502 to approach the insert plate 308 and squeeze the insert plate 308. The top block 502 is fixedly connected to one end of the hydraulic telescopic rod 501 near the insert plate 308. The side of the top block 502 near the insert plate 308 is set at an angle and can fit against the insert plate 308.

[0028] In another embodiment of this utility model, the length of the stud 408 is equal to the length between the rubber pad 405 and the screw block 402, ensuring that the stud 408 can press against the rubber pad 405 after being tightened, while the screw block 402 can press the washer 403, so that the stud 408 will not easily loosen.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
