[0021] The implementation principle of the above embodiment is: the cooperation of the sponge pad 2 and the placement slot 3 provides a stable placement position for the disassembly mechanism 4, and the detachable connection of the sponge pad 2 and the parts replacement slot 5 increases the flexibility of the maintenance package, which is convenient for maintenance personnel to manage the parts replacement slot 5 according to different maintenance needs, the hinge connection of the maintenance box 1 and the cover plate 6 and the setting of the buckle 8 on the cover plate 6 realize the opening and closing function of the maintenance box 1, which is convenient for maintenance personnel to operate.
[0022] Reference Figure 2The embodiment shown is that the dismounting mechanism 4 is composed of two semicircular fixed shells 10, which are the main part of the dismounting mechanism 4 and can be spliced into a complete fixed ring 11. In this embodiment, the edges of the two fixed shells 10 are connected through a clamping assembly 15. When the two fixed shells 10 are spliced, the abutting edges fit closely to form a circular fixed ring 11. The fixed ring 11 is integrally connected with the threaded holes, which are uniformly distributed on the circumference of the fixed ring 11. The position and number of the threaded holes are designed according to the fixing and dismounting requirements of the rotary joint to ensure that the rotary joint can be uniformly stressed during operation. The threaded holes are connected with threaded columns 12 through threads. The threaded columns 12 can rotate and axially move in the threaded holes. Through the cooperation of threads, precise position adjustment is realized. The contact part 13 at one end of the threaded column 12 close to the fixed ring 11 is fixedly connected with the threaded column 12 to ensure that it can be in good contact with the surface of the rotary joint and will not cause damage to the rotary joint. The other end of the threaded column 12 is fixedly connected with a handle 14, which facilitates the maintenance personnel to operate the threaded column 12. By rotating the handle 14, torque is transmitted to the threaded column 12 to make the threaded column 12 rotate and move in the threaded hole, thereby realizing the operation of the rotary joint.
[0023] The implementation principle of the above embodiment is that the two semicircular fixed shells 10 are spliced to form a fixed ring 11, which provides a firm basic structure for subsequent operation. The threaded connection of the threaded holes on the fixed ring 11 with the threaded columns 12 enables the maintenance personnel to adjust the position of the threaded columns 12 by rotating the threaded columns 12, thereby driving the contact part 13 to approach or move away from the rotary joint to realize the dismounting or installation of the rotary joint. The connection of the threaded column 12 with the handle 14 enables the maintenance personnel to easily apply torque, and the connection of the contact part 13 with the rotary joint is realized by abutting. When the contact part 13 is in contact with the rotary joint, by moving the threaded column 12, pressure or tension can be applied to the rotary joint to complete the dismounting or installation operation.
[0024] Referring to Figure 3 , Figure 4 , Figure 5In the shown embodiment, the clamping assembly 15 is arranged on the fixing ring 11, wherein the clamping hole 16 is arranged at the upper and lower ends of one of the fixing shells 10, and the clamping block 17 on the other fixing shell 10 corresponds to the clamping hole 16. In this embodiment, the clamping hole 16 is integrally formed with the fixing shell 10, and the position and size thereof are determined according to the size and shape of the clamping block 17 to ensure that the clamping block 17 can be smoothly inserted. The clamping block 17 is fixedly connected with the other fixing shell 10, and the position and shape thereof are matched with the clamping hole 16 to ensure that the clamping block 17 can be accurately inserted into the clamping hole 16. The sliding groove 19 arranged on the clamping block 17 is matched with the wedge block 20, and the sliding groove 19 provides a sliding space for the wedge block 20 to enable the wedge block 20 to linearly slide therein. The wedge block 20 slides in the sliding groove 19 and forms a cooperation relationship with the limiting hole 18. When the clamping block 17 is inserted into the clamping hole 16, the wedge block 20 will enter the limiting hole 18 in the sliding process. The limiting hole 18 is integrally formed with the fixing shell 10, and the position and size thereof are matched with the wedge block 20 to ensure that the wedge block 20 can be accurately inserted and clamped.
[0025] The implementation principle of the above embodiment is that the connection relationship of the clamping assembly 15 ensures that the two fixing shells 10 can be firmly spliced to form the fixing ring 11. When the two fixing shells 10 are close to each other, the clamping block 17 is inserted into the clamping hole 16, and at this time the wedge block 20 slides in the sliding groove 19. When the clamping block 17 is completely inserted into the clamping hole 16, the wedge block 20 will enter the limiting hole 18 under the action of its own shape and position, thereby locking the two fixing shells 10 together to prevent the fixing shells 10 from being separated due to stress when the rotary joint is operated.
[0026] Referring to Figure 5 In the shown embodiment, the wedge block 20 is fixedly connected with the reset compression spring 21, one end of the reset compression spring 21 is connected with the wedge block 20, and the other end is fixed in the sliding groove 19. In this embodiment, the reset compression spring 21 is in a compressed state, and the length and elastic coefficient thereof are designed according to the movement and locking requirements of the wedge block 20. The connection between the reset compression spring 21 and the wedge block 20 and the sliding groove 19 is close, and the elastic force of the reset compression spring 21 drives the wedge block 20 to move towards the limiting hole 18.
[0027] The implementation principle of the above embodiment is that the reset compression spring 21 plays an automatic locking role in the clamping assembly 15. When the clamping block 17 is inserted into the clamping hole 16, the wedge block 20 will automatically slide into the limiting hole 18 due to the elastic force of the reset compression spring 21, thereby realizing the automatic locking of the clamping block 17, and the firm connection of the two fixing shells 10 can be ensured without additional operation. When it is necessary to separate the two fixing shells 10, the maintenance personnel press the wedge block 20 into the sliding groove 19 against the elastic force of the reset compression spring 21, so that the clamping block 17 can be pulled out of the clamping hole 16.
[0028] The working principle of the device is that when the expanded tobacco rotary joint needs to be repaired, the maintenance personnel first open the cover plate 6 of the maintenance box 1, disengage the cover plate 6 from the maintenance box 1 through the buckle 8, then take out the disassembly mechanism 4 from the sponge pad 2 placing groove 3, splice the two semicircular fixing shells 10 into a fixed ring 11 around the rotary joint, firmly connect the two fixing shells 10 by using the clamping assembly 15, that is, the clamping block 17 is inserted into the corresponding clamping hole 16, and the wedge-shaped block 20 is inserted into the limiting hole 18 under the action of the reset compression spring 21, so that the clamping block 17 is prevented from being pulled out, then rotate the rotating handle 14 to drive the threaded column 12 to move along the threaded hole, so that the contact part 13 at one end of the threaded column 12 abuts against the rotary joint and gradually exerts pressure, thereby disassembling the rotary joint from the equipment, and after the disassembly is completed, the maintenance personnel take out the required maintenance parts from the corresponding part replacement groove 5 according to the specific damaged parts of the rotary joint to replace the parts.
[0029] The working principle of the device has been described in the above embodiment, and the above embodiment only expresses several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
