Description

Technical Field

[0001] The utility model relates to the technical field of pipeline linings, in particular to a flanging device for pipeline linings. Background Art

[0002] The pipe lining is a kind of pipe skeleton with steel or hard structure as the outer part, and wear-resistant, corrosion-resistant and high-temperature resistant rubber as the inner lining layer. The physical and chemical properties of rubber itself reduce the effects of pipeline conveying medium on the external structure, such as impact force and corrosion. Due to the buffering effect of rubber, the service life of the pipeline is greatly extended, and the cost of users is reduced. The lining is generally flanged at the end of the pipe lining. After searching, the Chinese patent with publication number CN217373459U discloses a flange device for pipe lining, a hydraulic cylinder, a cylinder seat, the hydraulic cylinder is installed on one side of the outer wall of the cylinder seat by bolts, a connecting mechanism is arranged on the cylinder seat, and the liner pipe is arranged on the connecting mechanism. The connecting mechanism is used to place the liner pipe. The flanging die is arranged on the connecting mechanism, the driving mechanism is arranged on the cylinder seat and is used to drive the flanging die to move, the mica heating ring is arranged on the connecting mechanism, and the inner support member is arranged in the inner lining pipe. When it is used, the inner support member is first placed in the inner lining pipe and fixed, and the mica heating ring and the flanging die are used to perform electric heat treatment on the joint of the inner lining pipe at the same time. When the inner lining pipe is evenly heated, the specific heating time can be appropriately changed according to the on-site environment. The engineering hydraulic cylinder provides thrust to push the flanging die forward, extrude and flange the melted part of the inner lining pipe, and withdraw the flanging die after it cools naturally, and the flanging of the inner lining pipe is completed. However, this flanging method can easily push the inner lining pipe into the pipe and form a lift, which can cause the inner lining pipe to separate from the inner wall of the pipe locally.

[0023] Example:

[0024] See also Figure 1-5 A flanging device for pipe lining comprises a fixed plate 1, one side of the fixed plate 1 is provided with an inner wall sliding structure of the liner pipe which can rotate circumferentially and move horizontally, and the other side of the fixed plate 1 is provided with a flanging structure, a positioning structure and a push-pull structure. The flanging structure comprises a plurality of flanging mechanisms which are evenly distributed circumferentially on the fixed plate 1, the flanging mechanisms comprise two groups of heating flanging strips 2 which are symmetrically connected to the fixed plate 1 for rotation, the flanging structure further comprises a flanging driving mechanism which synchronously drives two groups of heating flanging strips 2 in the plurality of flanging mechanisms to rotate inward and outward, after the heating flanging strips 2 have flanging the liner pipe, the local part of the flanging can be heated to cause it to deform and maintain the flanging state.

[0025] Specifically, two groups of heating flanging strips 2 symmetrically rotatably connected to the fixed plate 1 are rotationally connected to the fixed plate 1 through a group of fixed shafts, one group of heating flanging strips 2 is rotationally connected to the fixed shaft through a leveling frame 14 that keeps the two groups of heating flanging strips 2 in the same rotation plane, and the leveling frame 14 is connected to the other group of heating flanging strips 2 through a flipping transmission assembly. Through the leveling frame 14, the two heating flanging strips 2 are kept in the same rotation plane, and with the cooperation of the flipping transmission assembly, one of the heating flanging strips 2 is driven to rotate outward, thereby ensuring that the two heating flanging strips 2 simultaneously flanging the inner liner tube to both sides during flanging.

[0026] Specifically, the flanging drive mechanism includes a fixed frame 8 which is arranged between multiple groups of flanging mechanisms and fixedly connected to the fixed plate 1. A flat toothed disk 9 which is rotatably connected to the fixed plate 1 is arranged at a position between the multiple groups of flanging mechanisms. A flat gear 11 which is meshed with the flat toothed disk 9 is fixedly connected to one of the heating flanging strips 2. A flanging motor 10 for driving the flat toothed disk 9 to rotate is fixedly connected to the fixed frame 8. The flanging motor 10 is started to make the output shaft of the flanging motor 10 rotate clockwise or counterclockwise, thereby driving the flat toothed disk 9 to rotate clockwise or counterclockwise, thereby driving the flat gear 11 to rotate counterclockwise or clockwise, thereby driving one of the multiple groups of flanging mechanisms to rotate counterclockwise or clockwise, and through the cooperation of the flipping transmission assembly, the other heating flanging strip 2 is driven to rotate clockwise or counterclockwise, thereby driving the two heating flanging strips 2 in each group of flipping mechanisms to rotate outward or inward at the same time. When rotating outward, the flanging operation can be performed, and when rotating inward, the heating flanging strip 2 can be retracted.

[0027] Specifically, the flipping transmission assembly includes a transmission bevel gear 13 and two driving bevel gears 12. The two driving bevel gears 12 are respectively fixedly mounted on a leveling frame 14 fixedly connected to one of the heating flanging strips 2 and the other heating flanging strip 2, and the transmission bevel gear 13 is arranged between the two driving bevel gears 12 and is rotatably connected to the fixed frame 8. The two driving bevel gears 12 are both meshed with the transmission bevel gear 13. Through the meshing of the transmission bevel gear 13 and the driving bevel gear 12, when one of the heating flanging strips 2 rotates, it drives the other heating flanging strip 2 to rotate in the opposite direction at the same rotation speed, thereby ensuring the stability of the flanging.

[0028] Specifically, the push-pull structure includes a push-pull frame 5, on which are fixedly connected a plurality of legs 6 which are cross-arranged between two adjacent sets of flanging mechanisms, and the plurality of legs 6 are all fixedly connected to the fixed plate 1.

The position calibration instrument 7 and the flanging motor 10 are both electrically connected to the controller. When the position calibration instrument 7 detects that it has reached the end position of the pipe, it transmits a signal to the controller, and the controller transmits the signal to the flanging motor 10, thereby starting the flanging motor 10, thereby driving a plurality of sets of flanging mechanisms to perform flanging processing on the liner pipe mounted in the pipe.

[0030] Specifically, the inner wall sliding structure of the liner tube includes multiple groups of universal sliding mechanisms circumferentially arranged on the fixed plate 1, and the universal sliding mechanism includes a fixed ball cover 3 fixedly installed on the fixed plate 1, and a universal roller 4 that can rotate in all directions is arranged in the fixed ball cover 3. Through the cooperation of the fixed ball cover 3 and the universal roller 4, it can be conveniently extended into the inner liner tube for horizontal movement, and can also ensure circumferential rotation in the inner liner tube.

[0031] When in use, the push-pull structure is held by hand to make the sliding structure of the inner wall of the liner tube extend into the liner tube. The inner wall sliding structure of the liner tube can facilitate the fixed plate 1 to be pushed into the liner tube and can be moved in the liner tube. The positioning structure detects that the flanging structure moves to the end of the pipe to be flanging position, and the flanging drive mechanism is started to drive two groups of symmetrically rotating heating flanging strips 2 connected to the fixed plate 1 in the multiple groups of flanging mechanisms to rotate to both sides, so as to facilitate flanging processing at multiple points. Then, as the inner wall sliding structure of the liner tube can drive the whole to rotate circumferentially in the liner tube, the multiple groups of flanging mechanisms can be cooperated to completely flanging the liner tube. After the flanging plate processing is completed, the whole can be pulled out of the liner tube through the push-pull structure.
