[0002] During the operation of drum granulation equipment, the sealing device of the drum granulation equipment needs to be disassembled and assembled frequently. The sealing device includes a sealing cover, and the sealing cover is connected to the body of the drum granulation equipment by an eyebolt. The stud thread of the eyebolt is inserted into the body of the drum granulation equipment. At the same time, the edge of the sealing cover is hinged to the body of the drum granulation equipment, that is, the sealing cover is set as a movable flip cover to ensure that the sealing cover will not fall off after the sealing device releases the seal of the drum granulation equipment. In order to limit the sealing cover to be stably set relative to the drum granulation equipment by the eyebolt, a notch is provided at the edge of the sealing cover, and the eyebolt penetrates through the notch, so as to facilitate the tightening of the sealing cover by the eyebolt after the material is put in, and at the same time provide support for the sealing cover to be turned over to release the seal of the drum granulation equipment.

[0003] A hand valve for discharging residual liquid is provided in the middle of the sealing cover. The hand valve protrudes from the sealing cover by about 10 cm. The protruding length is similar to the length of the eyebolt protruding from the sealing cover, and the eyebolt is arranged adjacent to the hand valve. When using an ordinary steel pipe or other temporary tools to penetrate into the eyebolt for rotation and disassembly, it is relatively laborious, and it is easily blocked by the liquid discharge hand valve and is prone to falling off, which poses a certain safety hazard. At the same time, there is currently no tool for disassembling the eyebolt. Therefore, it is rather troublesome to control the rotation of the eyebolt. Content of the Utility Model

[0024] Embodiment 1

[0025] As Figure 1 , Figure 2 , Figure 3 shown, a special disassembly tool for a ring bolt includes a force application component 1 and a sleeve plate 2. The sleeve plate 2 is set in a U-shaped structure and is arranged at the end of the force application component 1. The side of the sleeve plate 2 away from the force application component 1 is an opening. The sleeve plate 2 being set in a U-shaped mechanism facilitates sleeving the sleeve plate 2 on the annular column of the ring bolt, that is, the annular column is arranged parallel to the sleeve plate 2 in the middle thereof, providing support for the sleeve plate 2 to drive the ring bolt to rotate. The force application component 1 includes a grip 11 and a connection mechanism 3. A sleeve 12 is arranged at the end of the grip 11. The length of the sleeve 12 is greater than the thickness of the grip 11. The connection mechanism 3 passes through the sleeve 12 and is connected to the sleeve plate 2 at the same time. Under the action of the connection mechanism 3, the grip 11 can rotate reversely relative to the sleeve plate 2, and can control the grip 11 and the sleeve plate 2 to rotate synchronously in the same direction. In this way, it is convenient for the staff to hold the grip 11 to drive the sleeve plate 2 to rotate. At the same time, the sleeve plate is sleeved on the annular column of the ring bolt, thereby driving the ring bolt to rotate. When the grip 11, the sleeve plate 2 and the ring bolt rotate a certain angle, the staff can rotate the grip 11 reversely relative to the sleeve plate 2 to the original position, thus changing the situation that the grip 11 rotates synchronously with the ring bolt for multiple weeks, and avoiding the influence of the existence of the hand valve on the rotation of the ring bolt.

[0026] As Figure 3 , Figure 4 , Figure 5As shown, in order to facilitate the handle 11 to rotate in the opposite direction relative to the sleeve plate 2, the connecting mechanism 3 includes a connecting column 31, a ratchet 34 and a snap plate 36. One end of the connecting column 31 is set to a first polygonal groove 33, and the other end is set to a second polygonal groove 38. The ratchet 34 and the snap plate 36 are set at both ends of the connecting column 31, and the side surfaces close to each other are respectively provided with a first polygonal column 35 and a second polygonal column 37. The polygonal columns are connected and inserted into the polygonal grooves by connecting bolts. With the cooperation of the polygonal columns and the polygonal grooves, the snap plate 36 and the ratchet 34 rotate synchronously with the connecting column 31, so as to provide support for driving the sleeve plate 2 to rotate when the handle 11 rotates. The snap plate 36 is fixedly connected to the sleeve plate 2, the outer diameter of the ratchet 34 is smaller than the diameter of the connecting column 31, the diameter of the connecting column 31 is slightly smaller than the inner diameter of the sleeve 12, and a brake plate 13 is provided in the gap between the ratchet 34 and the sleeve 12. The brake plate 13 is hinged to the sleeve 12 and cooperates with the ratchet 34 to control the sleeve plate 2 and the handle 11 to rotate synchronously when the handle 11 rotates forward. When the handle 11 rotates reversely, the brake plate 13 can rotate relative to the ratchet 34 to provide support for the reversal of the handle 11.

[0027] like Figure 3 , Figure 4 As shown, in order to make the handle 11 movably arranged relative to the connecting column 31, an annular groove 32 is arranged on the connecting column 31, and the annular groove 32 is located on the inner side of the sleeve 12. Two mounting holes 14 are symmetrically arranged on the sleeve 12. A limiting plate 15 is connected to each mounting hole 14 through a connecting bolt. The outer end surface of the limiting plate 15 and the outer side surface of the sleeve 12 are located on the same curved surface, and the inner end surface protrudes from the inner side surface of the sleeve 12 and is inserted into the annular groove 32. With the cooperation of the limiting plate 15 and the annular groove 32, the sleeve 12 is detachable and movably sleeved on the connecting column 31, which provides convenience for the handle 11 to rotate forward and backward relative to the connecting column 31.

[0028] Example 2

[0029] like Figure 1 , Figure 2 , Figure 3As shown in the figure, a special disassembly tool for a ring bolt includes a force application component 1 and a sleeve plate 2. The sleeve plate 2 is arranged in a U-shaped structure and is provided at the end of the force application component 1. The side of the sleeve plate 2 away from the force application component 1 is an opening. The sleeve plate 2 is arranged in a U-shaped mechanism, which is convenient for sleeving the sleeve plate 2 on the annular column of the ring bolt, that is, the annular column is arranged parallel to the sleeve plate 2 in the middle thereof, providing support for the sleeve plate 2 to drive the ring bolt to rotate. The force application component 1 includes a grip 11 and a connection mechanism 3. A sleeve 12 is provided at the end of the grip 11. The length of the sleeve 12 is greater than the thickness of the grip 11. The connection mechanism 3 passes through the sleeve 12 and is connected to the sleeve plate 2 at the same time. Under the action of the connection mechanism 3, the grip 11 can rotate reversely relative to the sleeve plate 2, and the grip 11 can be controlled to rotate synchronously in the same direction as the sleeve plate 2. In this way, it is convenient for the staff to hold the grip 11 to drive the sleeve plate 2 to rotate. At the same time, the sleeve plate is sleeved on the annular column of the ring bolt, thereby driving the ring bolt to rotate. When the grip 11, the sleeve plate 2 and the ring bolt rotate a certain angle, the staff can rotate the grip 11 reversely relative to the sleeve plate 2 to the original position, which changes the current situation that the grip 11 rotates synchronously with the ring bolt for multiple weeks, avoiding the influence of the presence of the hand valve on the rotation of the ring bolt.

[0030] As Figure 3 , Figure 4 , Figure 5 As shown in the figure, in order to facilitate the reverse rotation of the grip 11 relative to the sleeve plate 2, the connection mechanism 3 includes a connecting column 31, a ratchet 34 and a buckle plate 36. One end of the connecting column 31 is provided with a first polygonal groove 33, and the other end is provided with a second polygonal groove 38. The ratchet 34 and the buckle plate 36 are arranged at both ends of the connecting column 31. The mutually adjacent side surfaces are respectively provided with a first polygonal column 35 and a second polygonal column 37. The polygonal columns are connected by connecting bolts and inserted into the polygonal grooves. Under the cooperation of the polygonal columns and the polygonal grooves, the buckle plate 36 and the ratchet 34 rotate synchronously with the connecting column 31, providing support for driving the sleeve plate 2 to rotate when the grip 11 rotates. The buckle plate 36 is fixedly connected to the sleeve plate 2. The outer diameter of the ratchet 34 is smaller than the diameter of the connecting column 31. The diameter of the connecting column 31 is slightly smaller than the inner diameter of the sleeve 12. A brake plate 13 is arranged in the gap between the ratchet 34 and the sleeve 12. The brake plate 13 is hinged to the sleeve 12 and cooperates with the ratchet 34 to control the sleeve plate 2 to rotate synchronously with the grip 11 when the grip 11 rotates forward. When the grip 11 rotates reversely, the brake plate 13 can rotate relative to the ratchet 34, providing support for the reverse rotation of the grip 11.

[0031] As Figure 3 , Figure 4As shown, in order to make the handle 11 movably arranged relative to the connecting column 31, an annular groove 32 is arranged on the connecting column 31, and the annular groove 32 is located on the inner side of the sleeve 12. Two mounting holes 14 are symmetrically arranged on the sleeve 12. A limiting plate 15 is connected to each mounting hole 14 through a connecting bolt. The outer end surface of the limiting plate 15 and the outer side surface of the sleeve 12 are located on the same curved surface, and the inner end surface protrudes from the inner side surface of the sleeve 12 and is inserted into the annular groove 32. With the cooperation of the limiting plate 15 and the annular groove 32, the sleeve 12 is detachable and movably sleeved on the connecting column 31, which provides convenience for the handle 11 to rotate forward and backward relative to the connecting column 31.

[0032] like Figure 6 , Figure 7 As shown, in order to improve the flexibility and practicality of the device, a buckle groove 21 is provided on the vertical side wall of the sleeve plate 2. The buckle groove 21 is provided along the length direction of the sleeve plate 2, and its length is less than the length of the sleeve plate 2. The cross section of the buckle groove 21 is the same as that of the buckle plate 36. The buckle plate 36 is provided in the buckle groove 21, and its length is less than the length of the buckle groove 21. With the cooperation of the buckle plate 36 and the buckle groove 21, the force-applying assembly 1 is stably connected to the sleeve plate 2, and the position of the sleeve plate 2 relative to the force-applying assembly 1 can be adjusted according to the use requirements, and convenience is provided for the rapid disassembly and assembly of the force-applying assembly 1 and the sleeve plate 2.
