[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vibrating screen plate auxiliary disassembly device includes: two symmetrically arranged seat plates and a support plate disposed in the two seat plates. The two seat plates and the two support plates are both U-shaped. A pressure rod bushing is sleeved in the adjacent side wall of the two support plates. A positioning shaft is provided between the two pressure rod bushings. Both ends of the positioning shaft extend into the adjacent pressure rod bushing.

[0007] The positioning shaft is fitted with a lever-type tube clamp, and a pressure rod is provided above the lever-type tube clamp. Slots are provided on both sides of the pressure rod. A hanging ring is fixedly connected to one end of the pressure rod. A hanging chain is provided below the hanging ring. A hook is fixedly connected to the bottom end of the hanging chain. A fixing mechanism connected to the pressure rod is provided on the outside of the lever-type tube clamp.

[0008] The fixing mechanism includes an arc-shaped seat, and an arc-shaped groove adapted to the outside of the pressure rod is opened in the middle of the top of the arc-shaped seat. Both ends of the arc-shaped seat are provided with mounting cavities. Both ends of the arc-shaped seat are provided with insertion holes, and the insertion holes are connected to the mounting cavities. Both mounting cavities are provided with limiting plates, and the insertion rod is sleeved in the limiting plates.

[0009] One end of the insertion rod extends to the outside of the insertion hole and is inserted into the slot, while the other end of the insertion rod extends to the outside of the arc-shaped seat. A spring is sleeved on the outside of the insertion rod, and the two ends of the spring are fixedly connected to the inner wall of one side of the mounting cavity and the adjacent side wall of the limiting plate, respectively.

[0010] Furthermore, threaded holes are provided at both ends of the outer surfaces of the two pressure rod bushings and the outer surfaces of the positioning shaft.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As attached Figure 1 To be continued Figure 7 As shown:

[0029] Example 1:

[0030] This utility model provides an auxiliary disassembly device for a vibrating screen plate, including two symmetrically arranged seat plates 1 and a support plate 2 disposed in the two seat plates 1. Both the two seat plates 1 and the two support plates 2 are U-shaped. Each of the adjacent side walls of the two support plates 2 is fitted with a pressure rod bushing 11. A positioning shaft 3 is provided between the two pressure rod bushings 11. Both ends of the positioning shaft 3 extend into the adjacent pressure rod bushing 11.

[0031] The positioning shaft 3 is fitted with a lever-type pipe clamp 5. A pressure rod 6 is provided above the lever-type pipe clamp 5. Slots are provided on both sides of the pressure rod 6. A hanging ring 7 is fixedly connected to one end of the pressure rod 6. A hanging chain 9 is provided below the hanging ring 7. A hook 10 is fixedly connected to the bottom end of the hanging chain 9. A fixing mechanism 4 connected to the pressure rod 6 is provided on the outside of the lever-type pipe clamp 5.

[0032] The fixing mechanism 4 includes an arc-shaped seat 401, and an arc-shaped groove adapted to the outside of the pressure rod 6 is provided in the middle of the top of the arc-shaped seat 401. Both ends of the arc-shaped seat 401 are provided with mounting cavities. Both ends of the arc-shaped seat 401 are provided with insertion holes, and the insertion holes are connected to the mounting cavities. Both mounting cavities are provided with limiting plates 402, and insertion rods 403 are sleeved inside the limiting plates 402.

[0033] One end of the insertion rod 403 extends to the outside of the insertion hole and is inserted into the slot, and the other end of the insertion rod 403 extends to the outside of the arc-shaped seat 401. A spring 404 is sleeved on the outside of the insertion rod 403. The two ends of the spring 404 are fixedly connected to the inner wall of one side of the mounting cavity and the adjacent side wall of the limiting plate 402, respectively.

[0034] As can be seen from the above, the two U-shaped seat plates 1 and the support plate 2 constitute the basic support structure of the device. They are symmetrically arranged to ensure force balance. The pressure rod sleeve 11 is sleeved on the side wall of the support plate 2 and passes through the positioning shaft 3 into the pressure rod sleeve 11. Then, the lever clamp 5 is sleeved on the outside of the positioning shaft 3 to fix the lever arm position of the pressure rod 6. The pressure rod 6 and the lever clamp 5 are fixed together by the fixing mechanism 4 to form a stable lever structure. The hanging ring 7 at one end of the pressure rod 6 is connected to the hanging chain 9 and the hook 10 through the press hook 8. When the personnel need to disassemble the screen plate, the hook 10 is hung on the vibrating screen plate to be disassembled. The personnel exert downward force on the other end of the pressure rod 6. Utilizing the rotation characteristics of the lever clamp 5, the pressure rod 6 forms a lever with the positioning shaft 3 as the fulcrum. The screen plate is hooked out through the hanging chain 9 and the hook 10, realizing the separation of the screen plate from the screen body.

[0035] When the work is completed, the operator can hold the pull block 406 and pull it outward, and use the pull rod 405 to drive the insertion rod 403, so that the insertion rod 403 disengages from the external slot of the pressure rod 6, and the pressure rod 6 and the lever-type pipe clamp 5 can be detached and removed for easy storage and transportation. When reassembly is required, the above operation is repeated. At this time, the spring 404 is compressed by the limiting plate 402. By placing the pressure rod 6 in the arc groove, the slot and the insertion hole are matched. Then the operator releases the pull block 406, and the spring 404 rebounds and pushes the limiting plate 402, which can drive the insertion rod 403 to re-insert into the slot, thus locking the pressure rod 6. This makes the pressure rod 6 and the lever-type pipe clamp 5 detachable and replaceable, which is simple and convenient.

[0036] The U-shaped base plate 1 and the support plate 2 provide a stable support foundation, and the elastic locking structure of the fixing mechanism 4 can be adapted to pressure bars 6 of various lengths. The flexible connection between the hanging chain 9 and the hook 10 can buffer the impact force during disassembly and prevent the screen plate or screen body from deforming due to rigid collision.

[0037] Example 2:

[0038] This embodiment is basically the same as the previous embodiment, except that threaded holes are provided at both ends of the two pressure rod bushings 11 and the positioning shaft 3, and fastening bolts 12 are provided at the top of the outer side of the pressure rod bushings 11. The bottom end of the fastening bolts 12 is fastened to the positioning shaft 3 through the threaded holes.

[0039] The hanging ring 7 is externally attached to a push-button hook 8, and the bottom end of the push-button hook 8 is externally wound and connected to the upper end of the hanging chain 9.

[0040] The other end of the insertion rod 403 extends to the outside of the arc-shaped seat 401 and is fixedly installed with a pull rod 405. The end of the pull rod 405 away from the insertion rod 403 is fixedly installed with a pull block 406, and the pull block 406 is conical.

[0041] The inner bottom of both seat plates 1 is provided with a slot that matches the bottom of the support plate 2, and the slot is U-shaped. Angle steel 13 is fixedly connected to the side walls of both ends of the two support plates 2.

[0042] Each of the angle steels 13 has a screw hole at one top and the inner bottom of the two base plates 1. Each of the angle steels 13 has a fixing screw 14 at one top. The bottom of each fixing screw 14 is fastened to the base plate 1 through the screw hole.

[0043] As can be seen from the above: the pressure rod bushing 11 and the positioning shaft 3 are rigidly connected by the fastening bolt 12. When the pressure rod 6 is subjected to force, the fastening bolt 12 locks the pressure rod bushing 11 and the positioning shaft 3 through the threaded hole to prevent them from rotating relative to each other. The push-type hook 8 on the outside of the hanging ring 7 is unlocked by pressing. Personnel can quickly connect or separate the hanging chain 9 from the hanging ring 7 by pressing the hook to save the connection time. The pull rod 405 and the pull block 406 at the end of the insertion rod 403 allow the operator to quickly control the extension and retraction of the insertion rod 403 by pulling the pull block 406, which facilitates the installation and removal of the pressure rod 6. The I-shaped groove at the bottom of the seat plate 1 is used to position the support plate 2, and then multiple angle steels 1 3. The support plate 2 and the seat plate 1 are rigidly connected by fixing screws 14. The bottom end of the support plate 2 is inserted into the slot, and the fixing screws 14 are tightened through the screw holes of the angle steel 13 and the seat plate 1. At the same time, multiple angle steels 13 can also provide stable fixation between the support plate 2 and the seat plate 1, thereby realizing quick loading and unloading between the support plate 2 and the seat plate 1, which is convenient for personnel to store, transport or assemble. Thus, the assembly of the disassembly device does not require professional tools, which is convenient for personnel to operate. Moreover, the parts used are of good quality and inexpensive, resulting in low operating costs. It improves the disassembly efficiency, operation convenience and scene adaptability of the device, and is suitable for disassembly operations of vibrating screen plates of different coal preparation plants and different specifications.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
