Description

Technical Field

[0001] This utility model relates to the technical field of toothed roller crushers, specifically to a tooling for replacing the crushing tooth plates of a toothed roller crusher. Background Technology

[0002] Toothed roll crushers are mechanical equipment used for crushing medium- to low-hardness brittle materials. They are mainly used in coal, mining, metallurgy, sand and gravel yards and coal preparation plants. Their core function is to generate shearing force through the counter-rotation of double or four toothed rolls to split and crush materials such as coal, coke, and coal gangue. They are characterized by a large crushing ratio, uniform particle size, and low over-crushing rate.

[0003] Toothed roll crushers are widely used in crushing medium- and low-hardness minerals such as barite and limestone due to the advantage that the crushing toothed plates can be partially replaced after wear. However, when replacing toothed plates on site, the distance between the roller body and the frame of the toothed roll crusher is usually ≤300mm. When manually carrying a single toothed plate weighing 30-80kg, it is difficult to exert force and multiple people are required to lift it, which poses a risk of injury. In addition, the toothed plates need to be completely aligned with the roller body mounting groove. The traditional method relies on manual prying for adjustment, which takes 15-30 minutes for a single alignment, resulting in low efficiency. Moreover, after long-term compression and wear, the toothed plates become tightly stuck to the roller body mounting groove, requiring the use of pry bars or sledgehammers to strike, which can easily damage the surface of the toothed plates or roller body.

[0004] Therefore, this utility model provides a tooling for replacing the crushing tooth plates of a toothed roller crusher to solve the above problems. Utility Model Content

[0005] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a tooling for replacing the crushing tooth plates of a toothed roller crusher. This tooling solves the problem that when replacing tooth plates on-site, the distance between the roller body and the frame of the toothed roller crusher is usually ≤300mm. When manually carrying a single tooth plate weighing 30-80kg, it is difficult to exert force and multiple people are required to lift it, which poses a risk of injury. Furthermore, the tooth plate needs to be completely aligned with the roller body mounting groove. Traditional methods rely on manual prying for adjustment, which takes 15-30 minutes per alignment, resulting in low efficiency. Moreover, after long-term compression and wear, the tooth plate becomes tightly stuck to the roller body mounting groove, requiring the use of pry bars or sledgehammers to strike it, which can easily damage the surface of the tooth plate or roller body.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tooling for replacing the crushing tooth plates of a toothed roller crusher includes a frame, an L-shaped support plate on the top of the frame, an electromagnet base mounted on the L-shaped support plate, and the L-shaped support plate being mounted on the frame via the electromagnet base. A lifting plate is provided on one side of the L-shaped support plate, a sliding groove is provided on the lifting plate, a slider is slidably connected in the sliding groove, a clamp for fixing the tooth plate is provided on the slider, a first adjusting component for lateral movement of the slider is provided on the lifting plate, and a second adjusting component for lifting and lowering the lifting plate is provided on the L-shaped support plate.

[0009] Preferably, the clamp further includes an eccentric wheel rotatably connected to the clamp seat, a handle is fixedly connected to the eccentric wheel, the clamp seat has two limiting holes, and limiting pins are inserted into the limiting holes, with the handle located between the two limiting pins.

[0010] Preferably, the first adjustment component includes a second fixed base mounted on the lifting plate and a first motor. The output shaft of the first motor is equipped with a first screw, and the first screw is rotatably connected to the second fixed base. The top end of the slider is threadedly connected to the first screw.

[0011] Preferably, the lifting plate is fixedly connected to two guide rails, the slider is T-shaped, and the two ends of the slider are slidably connected to the two guide rails respectively.

[0012] Preferably, the second adjustment component includes a first fixed seat fixedly connected to the L-shaped support plate and a second motor mounted on the L-shaped support plate. The output shaft of the second motor is equipped with a second screw, and a linkage seat is threadedly connected to the second screw. The bottom surface of the linkage seat is fixedly connected to the lifting plate.

[0013] Preferably, a guide rod is fixedly connected to the first fixed base, and one end of the lifting plate is slidably connected to the guide rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This device uses an electromagnet base to fix an L-shaped support plate, a clamp to hold the toothed plate, and a motor-driven adjustment component to achieve the lifting and lateral movement of the toothed plate. It eliminates the need for manual handling of toothed plates weighing 30-80kg, avoids the operation mode of multiple people working together to lift and transport, solves the problem of difficulty in exerting force when manually handling, avoids the safety hazard of being injured by the toothed plate from the root, and greatly reduces the manpower input.

[0016] 2. This device, through the coordinated arrangement of the first and second adjustment components, achieves precise control over the lifting and lateral movement of the toothed plate. With the assistance of guide rods and guide rails for positioning, it eliminates the need for manual prying and adjustment, and can quickly align the toothed plate with the roller mounting groove, significantly shortening the overall operation time for toothed plate disassembly and installation, and greatly improving replacement efficiency.

[0017] 3. The clamps of this device adopt fixed and movable clamps with C-shaped groove structure. Stable clamping is achieved by eccentric wheel extrusion. There is no need to use pry bars or sledgehammers to separate the adhered toothed plates from the mounting grooves. The non-violent disassembly method avoids bumps to the surface of the toothed plates and also prevents surface damage caused by the transmission of impact force to the roller body. This extends the service life of the toothed plates and roller bodies and reduces equipment maintenance costs. Attached Figure Description

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] A tooling for replacing the crushing teeth of a toothed roller crusher, as shown in the attached figure. Figure 1-4 As shown, the machine includes a frame 1, which is an existing structure. The frame 1 is designed with a crushing roller, and the crushing roller has a toothed plate mounting groove. An L-shaped support plate 2 is set on the top of the frame 1. An electromagnet seat 3 is installed on the L-shaped support plate 2, and the L-shaped support plate 2 is installed on the frame 1 through the electromagnet seat 3. The electromagnet seat 3 becomes magnetic after being energized, and the L-shaped support plate 2 can be fixed on the frame 1 by means of the magnetism of the electromagnet seat 3 after being energized. After the electromagnet seat 3 is de-energized, the L-shaped support plate 2 can be easily removed from the frame 1. A lifting plate 4 is set on one side of the L-shaped support plate 2. A sliding groove 5 is opened on the lifting plate 4, and a slider 6 is slidably connected in the sliding groove 5.

[0025] In this embodiment, the slider 6 is provided with a clamp for fixing the toothed plate. The clamp includes a clamp seat 18 fixedly connected to the slider 6, a fixed clamping claw 14 fixedly connected inside the clamp seat 18, a movable clamping claw 15 slidably connected inside the clamp seat 18, and guide blocks 17 fixedly connected to both ends of the movable clamping claw 15. Guide grooves 16 are provided on both sides of the clamp seat 18, and one end of the guide block 17 is slidably connected to the guide groove 16.

[0026] Both the fixed gripper 14 and the movable gripper 15 are rod-shaped structures with C-shaped grooves, and the C-shaped grooves on the fixed gripper 14 and the movable gripper 15 are in relative positions. The movable gripper 15 can slide in the guide groove 16 through the guide block 17 to adjust the distance between the movable gripper 15 and the fixed gripper 14.

[0027] In this embodiment, the clamp also includes an eccentric wheel 19 rotatably connected to the clamp seat 18. A handle 20 is fixedly connected to the eccentric wheel 19. Two limiting holes 21 are provided on the clamp seat 18, and limiting pins 22 are inserted into the limiting holes 21. The handle 20 is located between the two limiting pins 22.

[0028] The eccentric wheel 19 is eccentrically set. When the handle 20 on the eccentric wheel 19 is between the two limit pins 22, the eccentric wheel 19 can squeeze the movable gripper 15, so that the movable gripper 15 is in the closest position to the fixed gripper 14. Then, the toothed plate can be clamped and fixed by means of the fixed gripper 14 and the movable gripper 15.

[0029] In this embodiment, the lifting plate 4 is provided with a first adjustment component for the lateral movement of the slider 6. The first adjustment component includes a second fixed seat 10 and a first motor 11 mounted on the lifting plate 4. The output shaft of the first motor 11 is equipped with a first screw 12, and the first screw 12 is rotatably connected to the second fixed seat 10. The top end of the slider 6 is threadedly connected to the first screw 12.

[0030] After the toothed plate is removed from the mounting slot, the toothed plate in the clamp can drive the first screw 12 to rotate through the output shaft of the first motor 11, and then move the clamp away from above the crushing roller by means of the movement of the slider 6 on the first screw 12.

[0031] In this embodiment, two guide rails 13 are fixedly connected to the lifting plate 4, the slider 6 is T-shaped, and the two ends of the slider 6 are slidably connected to the two guide rails 13 respectively.

[0032] The guide rail 13 guides the movement of the slider 6, improving the stability of the slider 6 during movement. The guide rail 13 also supports the slider 6, distributing the force when the clamp fixes the toothed plate and moves upward.

[0033] In this embodiment, the L-shaped support plate 2 is provided with a second adjustment component for lifting and moving the lifting plate 4. The second adjustment component includes a first fixed seat 7 fixedly connected to the L-shaped support plate 2 and a second motor 23 installed on the L-shaped support plate 2. The output shaft of the second motor 23 is equipped with a second screw 24, and a linkage seat 8 is threadedly connected to the second screw 24. The bottom surface of the linkage seat 8 is fixedly connected to the lifting plate 4.

[0034] The output shaft of the second motor 23 drives the second screw 24 to rotate, which enables the linkage seat 8 to drive the lifting plate 4 to move upward, and allows the slider 6 to quickly remove the toothed plate from the mounting slot through the clamp.

[0035] In this embodiment, a guide rod 9 is fixedly connected to the first fixed base 7, and one end of the lifting plate 4 is slidably connected to the guide rod 9. The guide rod 9 is used to guide the lifting plate 4 and improve the stability of the movement of the lifting plate 4.
