Description

Technical Field

[0001] The invention relates to the field of pipeline repair, and in particular to a CIPP pipeline repair device and a repair method thereof. Background Art

[0002] CIPP in-situ curing method is an underground pipeline repair process in the trenchless industry. It originated in the UK in the 1970s and is the most widely used trenchless repair technology for underground pipelines in the world. CIPP technology is widely used and is suitable for trenchless repair of gravity flow pipelines, water supply, gas and other pressure pipelines.

[0003] CIPP is a pipe repair technology. The principle is: a non-woven lined pipe or fiberglass, with a polymer coating (PU or PE) on the outside, is first impregnated with polyester resin or epoxy resin, and then flipped into the sewer or sewage pipe by water gravity or compressed air pressure, or (UV-cured fiberglass hose) dragged into the pipeline. Once the liner is fully installed in the main pipeline, it is heated with water, steam, or UV to cause the resin to react chemically and begin to cure, which takes about 4-8 hours. After the liner is cured, a new continuous pipeline with full structural strength will be formed in the original pipeline.

DETAILED DESCRIPTION

[0035] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0036] Reference Figures 1 to 8 A CIPP pipeline repair device shown includes a liner hose 1, a glue pouring assistant, a glue rolling device, and a pneumatic turning device;

[0037] The lining hose 1 is used to fit closely to the inner wall of the damaged pipe, thereby repairing the damaged pipe; the lining hose 1 is filled into the damaged pipe through the air pressure flipping device and fits closely to the inner wall of the pipe, thereby achieving the effect of local repair of the water pipe.

[0038] The glue pouring assistant is used to block one end of the lining hose 1 when pouring glue into the lining hose 1, so as to prevent the glue from flowing from one end of the lining hose 1 to the other end; the glue pouring assistant is used to clamp the lining hose 1 in the middle when pouring glue into the lining hose 1, so as to prevent the glue in the lining hose 1 from flowing to the other end of the lining hose 1 before rolling the glue.

[0039] The glue rolling device is used to flatten the lining hose 1 filled with glue, so that the glue in the lining hose 1 is gradually flattened from one end and filled to the other end of the lining hose 1; after the lining hose 1 filled with glue at one end passes through the glue rolling device, the glue evenly fills the lining hose 1, which is beneficial to the subsequent turning over and bonding process.

[0040] The pneumatic turning device comprises a sealing shell 2, a reel 3 for rolling up the lining hose 1, and a pneumatic turning mechanism for turning over the lining hose 1 and sending it into the damaged pipe. After the lining hose 1 is filled with glue and rolled, it is rolled on the reel 3 in a flat shape, and finally one end is pulled out of the sealing shell 2, and the lining hose 1 is turned over by the pneumatic turning mechanism, so that the glue-covered side of the lining hose 1 is turned outward and pressed against the wall of the damaged pipe, thereby realizing local trenchless repair.

[0041] The glue pouring assistant includes a first bead 4, a second bead 5, two tightening nuts 6 and two fastening bolts 7. The first bead 4 and the second bead 5 are arranged parallel to each other and the lining hose 1 passes between the first bead 4 and the second bead 5. The two fastening bolts 7 are respectively arranged at both ends of the first bead 4 and the second bead 5. Each fastening bolt 7 passes through the first bead 4 and the second bead 5 in sequence. The two tightening nuts 6 are respectively screwed on the two fastening bolts 7 to make the first bead 4 and the second bead 5 press the lining hose 1 against each other. First, use a bucket to prepare glue, and then use the glue pouring assistant to seal a section of the end of the lining hose 1. By rotating the two tightening nuts 6, the tightening nuts 6 move on the fastening bolts 7, so that the first bead 4 and the second bead 5 are pressed against each other until the lining hose 1 is stopped to prevent the glue from flowing to the other end of the lining hose 1.

[0042] The rubber rolling device includes a belt conveyor 8, a flattening roller 9 and a pressing roller 10. The belt conveyor 8 is arranged in an inclined state. A driving motor 11 is fixedly arranged below the belt conveyor 8. The output shaft of the driving motor 11 is connected to the belt conveyor 8 through a synchronous belt 12. The flattening roller 9 is arranged at the top of the upper end of the belt conveyor 8 through a lifting mechanism, and the pressing roller 10 is movably arranged at the top of the lower end of the belt conveyor 8. The driving motor 11 drives the belt conveyor 8 to work through the synchronous belt 12, so that the lining hose 1 on the belt conveyor 8 moves forward. In this process, the lining hose 1 is squeezed by the flattening roller 9 pressed against the belt conveyor 8, so that the glue at the front end of the lining hose 1 is evenly squeezed into the entire lining hose 1.

[0043] The lifting mechanism includes two triangular brackets 13, two threaded rods 14, a long rotating shaft 15 and a hand crank 16. The two triangular brackets 13 are respectively fixedly arranged on both sides of the upper end of the belt conveyor 8. The two threaded rods 14 are respectively arranged in the two triangular brackets 13. Each threaded rod 14 is perpendicular to the plane where the belt conveyor 8 is located. Each threaded rod 14 is axially connected to the triangular bracket 13. The triangular bracket 13 is provided with a strip accommodating groove 17 for accommodating the threaded rod 14. A crossbeam 18 is jointly arranged on the top of the two triangular brackets 13. The long rotating shaft 15 is axially arranged in the crossbeam 18 in a horizontal state. A first bevel gear 19 is fixedly arranged at both ends of the long rotating shaft 15. Each threaded rod The upper ends of 14 extend into the cross beam 18 and are fixedly connected to a second bevel gear 20, the two first bevel gears 19 correspond to the two second bevel gears 20 and mesh with each other, each threaded rod 14 is sleeved with a first slider 21 threadedly connected thereto, the flattening roller shaft 9 is arranged in a horizontal state and its two ends are respectively axially connected to the two first sliders 21, the hand crank 16 is arranged at one end of the top of the cross beam 18 and one end of the hand crank 16 extends to the inside of the cross beam 18, and a third bevel gear 22 is arranged at one end of the hand crank 16 extending into the cross beam 18, and a fourth bevel gear 23 is fixedly arranged on the back side of one of the first bevel gears 19, and the third bevel gear 22 and the fourth bevel gear 23 mesh with each other. The third bevel gear 22 is driven to rotate by the hand crank 16. Since the third bevel gear 22 is meshed with the fourth bevel gear 23, the fourth bevel gear 23 will drive the long rotating shaft 15 to rotate, and the rotation of the long rotating shaft 15 will drive the two first bevel gears 19 to rotate. Each threaded rod 14 is meshed with the first bevel gear 19 through the second bevel gear 20. Therefore, the two threaded rods 14 will also rotate with the rotation of the long rotating shaft 15, and then the two first sliders 21 are driven downward by the rotating synchronous belt 12 of the two threaded tubes, thereby driving the flattening roller 9 to descend through the two first sliders 21 until the lining hose 1 is pressed against the belt conveyor 8 below, thereby realizing the glue leveling process.

[0044] An L-shaped bracket 24 is fixedly provided on both sides of the lower end of the belt conveyor 8, and a guide shaft 25 extending vertically upward is fixedly provided on the top of each L-shaped bracket 24. A second slider 26 is slidably sleeved on each guide shaft 25, and the two ends of the pressing roller 10 are axially connected to the two second sliders 26. The pressing roller 10 is movably sleeved on the two guide shafts 25 through the two second sliders 26. The pressing roller 10 presses the lining hose 1 downward onto the belt conveyor 8 under the action of its own gravity, thereby preventing the tail of the lining hose 1 from deflecting during the glue spreading process.

[0045] One end of the sealed shell 2 is a tapered portion 27, and the pneumatic flipping mechanism is connected to the tapered portion 27. The winding shaft 3 is arranged on the inner side of the sealed shell 2, and the two ends of the winding shaft 3 are respectively axially connected to the inner wall of the sealed shell 2. A turntable handle 28 coaxially connected to the winding shaft 3 is provided on the outer side of the sealed shell 2. An openable sealed hatch cover 29 is provided at the end of the sealed shell 2 away from the tapered portion 27. A supporting base 30 is fixedly provided at the bottom of the sealed shell 2, and two oblique brackets 31 are fixedly provided on both sides of the supporting base 30. A limiting roller 32 is provided on the top of the two oblique brackets 31, and an axle seat 33 for the axial connection of the limiting roller 32 is provided on the top of each oblique bracket 31. After the glue-leveling process, the lining hose 1 is pressed into a flat shape. At this time, one end of the lining hose 1 is tied tightly with a cable tie, and the cable tie is fixed on the winding shaft 3. Finally, the winding shaft 3 is rotated by the turntable handle 28 to gradually roll the lining hose 1 on the winding shaft 3. During this process, the lining hose 1 is supported by the limiting rollers 32 at the top of the two oblique brackets 31 to prevent excessive friction between the lining hose 1 and the sealing shell 2.

[0046] One end of the sealed housing 2 is provided with a plurality of locking rockers 34 evenly distributed along the circumferential direction and used to fix the sealed hatch cover 29. Each locking rocker 34 is connected to the sealed housing 2 through a threaded short rod 35. One end of the threaded short rod 35 is hinged to the sealed housing 2, and the other end is used for the locking rocker 34 to be rotated. The outer edge of the sealed hatch cover 29 is evenly provided with a plurality of escape notches 36 for escaping the threaded short rods 35. The locking rocker 34 is located on the outer side of the sealed hatch cover 29 and is tightly pressed against the sealed hatch cover 29. After the liner hose 1 is completely rolled up on the reel 3, the sealed hatch cover 29 is closed. During this process, the threaded short rod 35 is horizontally rotated outward to enter the escape notch 36 of the sealed hatch cover 29. Finally, the locking rocker 34 is rotated to move toward the sealed housing 2 on the threaded short rod 35 until the sealed hatch cover 29 is fixed on the sealed housing 2.

[0047] The air pressure turning mechanism includes a connecting pipe 37, a connecting head 38 and a controller 39. A clamp 40 is used to lock one end of the connecting pipe 37 and the conical portion 27, the other end of the connecting pipe 37 and the connecting head 38, and the connecting head 38 and the lining hose 1. The controller 39 is arranged on the outer side of the sealed housing 2 to control the external air source to be filled into the sealed housing 2. After closing the sealed hatch 29, the free end of the lining hose 1 on the reel 3 is pulled out from the conical portion, one end of the lining hose 1 passes through the conical portion and the connecting pipe 37 in sequence, and finally passes through the connecting head 38. The end of the lining hose 1 that passes through is folded outward and sleeved on the outer end of the connecting head 38, and finally locked by the clamp 40. Finally, the charging of the external air source is controlled by the controller 39. As the air pressure inside the sealed housing 2 gradually increases, the lining hose 1 wound on the reel 3 passes through the connecting head 38 and gradually turns outward until it reaches the damaged part of the pipeline and is close to the inner wall, completing the local repair.

[0048] A repair method for a CIPP pipeline repair device, the method comprising the following steps:

[0049] S1, first use a bucket to prepare special glue, then use the glue pouring assistant to seal one end of the lining hose 1, and then pour the glue prepared in the bucket into the end close to the glue pouring assistant; after the glue raw materials are poured into the bucket, they need to be fully stirred and mixed, and after sealing a section of the lining hose 1 through the glue pouring assistant, pour the glue into one end of the lining hose 1.

[0050] S2, seal the end of the liner hose 1 away from the glue pouring assistant with tape, and cut an overflow port 41 at the end with a knife; the tape is used to prevent glue from overflowing from the tail end during glue spreading, and the overflow port 41 is used to allow excess water in the liner hose 1 to flow out.

[0051] S3, then use the glue rolling device to evenly roll out the glue at one end of the lining hose 1 and spread it throughout the entire lining hose 1, and the excess glue flows out from the overflow port 41 at the rear end of the lining hose 1; after being flattened by the rolling roller 9 of the glue rolling device, the glue evenly fills the entire lining hose 1, so as to facilitate the subsequent turning over and bonding process.

[0052] S4, then use a cable tie to seal one end of the liner hose 1 with the overflow port 41, and connect the end to the reel 3 through a rope, then pull the liner hose 1 into the sealed shell 2 through the turntable handle 28, and finally roll the liner hose 1 up on the reel 3; the flattened liner hose 1 must first be rolled up on the reel 3 in the sealed shell 2, and the outermost end of the liner hose 1 must be passed through the tapered portion, the connecting pipe 37 and the connecting head 38 in turn, and finally the passed-out end of the liner hose 1 must be fixed on the connecting head 38, so that in the subsequent process of gradually turning the liner hose 1 over and squeezing it out through air pressure, the liner hose 1 will not fall off the connecting head 38.

[0053] S5, when the lining hose 1 is completely rolled onto the reel 3, one end of the lining hose 1 is pulled out from the tapered portion 27 of the sealing shell 2 and extended from the connector 38, and then the extended end is flanged and sleeved on the connector 38, and finally locked with the clamp 40, the connector 38 is extended into the damaged pipe, and the external air source is started to be filled through the controller 39, and the lining hose 1 on the reel 3 is gradually squeezed into the damaged pipe by air pressure, and the turned-over lining hose 1 is fitted with the inner wall of the damaged pipe through the previously injected glue. After the lining hose 1 is fixed to the connector 38, the connector 38 is extended into the entrance of the pipeline, and the air pressure in the sealing shell 2 is continuously increased through the injection of the external air source, and the air pressure gradually squeezes the lining hose 1 outward through the position of the connector 38, and the lining hose 1 is gradually turned over in the process of extrusion, so that the side of the lining hose 1 with glue is fitted with the inner wall of the damaged pipe.
