Description

Technical Field

[0001] This utility model relates to the field of jaw plate replacement technology, specifically to a jaw plate replacement device for a jaw crusher. Background Technology

[0002] Jaw crushers are widely used crushing equipment in industries such as mining, metallurgy, and building materials. Their working principle is to crush materials through the squeezing action between the moving jaw plate and the fixed jaw plate. As a key wear part that directly participates in crushing, the upper and lower parts of the jaw plate do not wear evenly during long-term operation. In order to extend the service life of the jaw plate and reduce production costs, the upper and lower ends of the jaw plate are often swapped to make the wear more uniform.

[0003] The traditional method involves using lifting equipment to remove the jaw plate from the crusher and place it on the ground or a work platform. Operators then manually, or with the aid of auxiliary tools, remove the original top fixing, change the lifting point to the bottom of the jaw plate, and reposition it before placing it back into the crusher. This process requires multiple lifting and lowering operations, consuming significant manpower and time, leading to prolonged equipment downtime. Furthermore, the jaw plate is prone to swaying and rotation during lifting, and the time-consuming positioning further impacts work efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a jaw plate changing device for a jaw crusher, which solves the problem of reduced work efficiency caused by the need for multiple lifting, lowering, and positioning operations during jaw plate changing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a jaw plate changing device for a jaw crusher, comprising a fixed frame, a support base, a rotating pushing mechanism, a rotating winding mechanism, a traction cable, and a limiting connector. The support base is rotatably installed at the bottom of the fixed frame. The rotating pushing mechanism is located on the adjacent surfaces of the fixed frame and the support base, with its moving end and rotating end meshing with each other. The rotating winding mechanism is located on the surface of the support base, with its rotating end located inside the support base. One end of the traction cable is fixedly connected to the rotating end surface of the rotating winding mechanism and wound around the rotating end surface of the rotating winding mechanism. The other end of the traction cable is hinged to the limiting connector, which is inserted into the lifting lug of the jaw plate.

[0006] The fixed frame includes a top seat and a rotating seat. The rotating seat is fixedly installed at the bottom of the top seat, and the rotating seat is rotatably connected to the top of the support seat.

[0007] The rotating pushing mechanism includes an electric push rod, a transmission gear plate, and a transmission gear ring. The electric push rod is fixedly installed at the bottom of the top seat, the transmission gear plate is fixedly installed at the output end of the electric push rod, and the transmission gear ring is fixedly installed at the top of the support seat. The transmission gear ring and the rotating seat are on the same axis, and the transmission gear plate and the transmission gear ring are meshed together.

[0008] The rotary winding mechanism includes a winding roller, a transmission gear, and a motor. The winding roller is rotatably mounted inside the support base, the motor is fixedly mounted on the outside of the support base, and the transmission gear is located between the winding roller and the motor.

[0009] The number of take-up rollers is two sets, which are symmetrically arranged inside the support base. The surface of the take-up rollers is provided with multiple sets of equally spaced grooves. The traction steel cable is wound into the grooves on the surface of the take-up rollers and extends along both sides to the outside of the support base.

[0010] The transmission gears consist of three sets. One set of transmission gears is fixedly fitted to the output end of the motor, and the other two sets are fixedly fitted to one end of the two sets of take-up rollers, with the transmission gear at the motor located between the other two sets of transmission gears. Adjacent transmission gears are meshed together.

[0011] The limiting connector includes a connecting plate, a hinge, a slot, a hook, and a bolt fastener. The hinge is fixedly installed on the top of the connecting plate and is connected to the bottom end of the traction steel cable. The surface of the connecting plate has a slot, and the hook is slidably inserted into the inside of the slot. The bolt fastener passes through the inside of the slot and the top of the hook.

[0012] The number of slots is multiple sets, and the multiple sets of slots are arranged at equal intervals on the surface of the connecting plate.

[0013] The beneficial effects of this utility model are as follows: This invention uses a motor to drive the transmission gear at its output end to rotate. Through the meshing of adjacent transmission gears, two sets of take-up rollers rotate in the same direction. This causes one set of traction cables to be wound into the groove of the take-up roller, while the other set is fed out from the groove. This controls the jaw plate, fixed by the limiting connector, to be interchanged vertically. Simultaneously, an electric push rod drives the transmission gear plate to move horizontally. Through the meshing of the transmission gear plate and the transmission gear ring, the support base rotates at the rotating seat, causing the components on its surface and the jaw plate to rotate horizontally. The rotating take-up mechanism controls the jaw plate to flip along the vertical plane, while the rotating push mechanism controls the jaw plate to rotate horizontally. This eliminates the need to remove the jaw plate, place it on the ground, change its fixed position, and then lift it back to its original position. The jaw plate can be quickly interchanged at both ends and placed back in its original position, improving work efficiency. Multiple sets of traction cables and hooks connect and fix the jaw plate, ensuring stable movement during flipping and rotating, and preventing accidents such as tipping over.

[0017] Figure 1 - Figure 5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 5 The present invention will be further described below.

[0018] A jaw plate changing device for a jaw crusher includes a fixed frame 1, a support base 2, a rotating pushing mechanism 3, a rotating winding mechanism 4, a traction steel cable 5, and a limiting connector 6. The fixed frame 1 is located at the moving end of the lifting equipment. The support base 2 is rotatably installed at the bottom of the fixed frame 1. The rotating pushing mechanism 3 is located on the adjacent surfaces of the fixed frame 1 and the support base 2, with its moving end and rotating end meshing with each other. The rotating winding mechanism 4 is located on the surface of the support base 2, with its rotating end located inside the support base 2. One end of the traction steel cable 5 is fixedly connected to the rotating end surface of the rotating winding mechanism 4 and wound around the rotating end surface of the rotating winding mechanism 4. The other end of the traction steel cable 5 is hinged to the limiting connector 6, which is inserted into the lifting lug of the jaw plate. Specifically, the device is placed on the lifting equipment by the fixed frame 1, so that the device can be driven to move up and down. The support base 2 can rotate under the fixed frame 1 by the push of the rotating pushing mechanism 3. The rotation of the rotating winding mechanism 4 drives the traction steel cable 5 to be wound to its moving end surface, or sends the traction steel cable 5 out of the moving end surface. The traction steel cable 5 pulls the limiting connector 6 to move up and down. The upper and lower ends of the jaw plate are fixed by the limiting connector 6 to control its movement.

[0019] The fixed frame 1 includes a top seat 101 and a rotating seat 102. The top seat 101 is connected to the moving end of the lifting equipment, and the rotating seat 102 is fixedly installed at the bottom of the top seat 101. The rotating seat 102 is rotatably connected to the top of the support seat 2. Specifically, the top seat 101 enables the device to move up and down with the lifting equipment, thereby driving the jaw plate connected to the bottom of the device to be taken out or put into the jaw crusher, and the rotating seat 102 enables the support seat 2 to rotate stably at the bottom of the fixed frame 1.

[0020] The rotary pushing mechanism 3 includes an electric push rod 301, a transmission gear plate 302, and a transmission gear ring 303. The electric push rod 301 is fixedly installed at the bottom of the top seat 101, the transmission gear plate 302 is fixedly installed at the output end of the electric push rod 301, and the transmission gear ring 303 is fixedly installed at the top of the support seat 2. The transmission gear ring 303 and the rotating seat 102 are on the same axis. The transmission gear plate 302 and the transmission gear ring 303 are meshed. There are two sets of electric push rods 301 and transmission gear plates 302, which are arranged symmetrically about the transmission gear ring 303. Specifically, the electric push rod 301 drives the transmission gear plate 302 to move horizontally, and the transmission gear plate 302 drives the transmission gear ring 303 to rotate, thereby causing the support seat 2 to rotate on the surface of the rotating seat 102.

[0021] The rotary winding mechanism 4 includes a winding roller 401, a transmission gear 402, and a motor 403. The winding roller 401 is rotatably mounted inside the support base 2, the motor 403 is fixedly mounted on the outside of the support base 2, and the transmission gear 402 is disposed between the winding roller 401 and the motor 403. Specifically, the traction steel cable 5 is wound and wound onto its surface by the rotation of the take-up roller 401, or the traction steel cable 5 on its surface is released and sent out. The transmission gear 402 enables the motor 403 to drive the take-up roller 401 to rotate stably.

[0022] There are two sets of take-up rollers 401. The two sets of take-up rollers 401 are symmetrically arranged inside the support base 2. The surface of the take-up roller 401 is provided with multiple sets of equally spaced grooves. The traction steel cable 5 is wound into the grooves on the surface of the take-up roller 401 and extends along both sides to the outside of the support base 2. Specifically, the rotation of two sets of take-up rollers 401 causes the traction steel cables 5 to pull the two ends of the jaw plate, controlling its flipping. Multiple sets of traction steel cables 5 are evenly arranged in grooves on the surface of the take-up rollers 401, thereby ensuring that the jaw plate avoids tipping over during the flipping process as the take-up rollers 401 rotate.

[0023] There are three sets of transmission gears 402. One set of transmission gears 402 is fixedly sleeved to the output end of the motor 403, and the other two sets are fixedly sleeved to one end of the two sets of take-up rollers 401 respectively. The transmission gears 402 at the motor 403 are located between the other two sets of transmission gears 402, and the adjacent transmission gears 402 are meshed together. Specifically, through the meshing and transmission of three sets of transmission gears 402, the motor 403 can drive the two sets of take-up rollers 401 to rotate synchronously in the same direction.

[0024] The limiting connector 6 includes a connecting plate 601, a hinge 602, a slot 603, a hook 604, and a bolt fastener 605. The hinge 602 is fixedly installed on the top of the connecting plate 601 and is connected to the bottom end of the traction cable 5. The surface of the connecting plate 601 has a slot 603. The hook 604 is slidably inserted into the inside of the slot 603. The bolt fastener 605 passes through the inside of the slot 603 and the top of the hook 604. Specifically, the connecting plate 601 enables multiple sets of hooks 604 to stably lift the jaw plate, the hinge 602 facilitates stable flipping of the jaw plate, and the bolt fastener 605 facilitates changing the fixed position of the hooks 604.

[0025] The number of slots 603 is multiple, and the multiple sets of slots 603 are arranged at equal intervals on the surface of the connecting plate 601; Specifically, multiple sets of slots 603 facilitate the adjustment of the installation position of the hook 604, so that the hook 604 corresponds to the lifting lugs of various jaw plates.

[0026] In summary: When using this utility model, the operator installs the device at the lifting equipment. When it is necessary to change the upper and lower jaw plates inside the jaw crusher, the hook 604 is inserted into the corresponding slot 603, and the hook 604 is fixed by bolt fasteners 605. The hook 604 is then hung on the lifting lugs at the upper and lower ends of the jaw plate, and the jaw is lifted by the lifting equipment. The drive motor 403 drives the transmission gear 402 at its output end to rotate. Through the meshing transmission of adjacent transmission gears 402, the two sets of winding rollers 401 are driven to rotate in the same direction. A set of traction steel cables 5 is wound and wrapped around the concave part of the winding roller 401. Inside the trough, another set of traction steel cables 5 are fed out from the groove of the take-up roller 401, thereby causing the top of the jaw plate to move down and the bottom to move up, controlling it to flip over and swap the positions of the upper and lower ends. Then, the electric push rod 301 is driven to drive the transmission tooth plate 302 to move horizontally. Relying on the meshing of the transmission tooth plate 302 and the transmission tooth ring 303, the transmission tooth ring 303 rotates. The transmission tooth ring 303 drives the support seat 2 to rotate on the surface of the rotating seat 102, thereby controlling the components on its surface to rotate horizontally together with the jaw plate, so that the front and back sides are swapped. Continue to drive the lifting equipment to put the jaw plate back in its original position to complete the swapping operation.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
