Description

Technical Field

[0001] This invention relates to the field of pipeline repair technology, specifically to a trenchless pipeline repair epoxy resin adhesive injection device and method. Background Technology

[0002] With the rapid development of industry and urban construction, many factories and cities in my country have gradually transitioned from the construction era to the maintenance and management era. Underground pipe networks, in particular, suffer varying degrees of damage with age, and some pipelines are entering a period of high accident incidence. Therefore, planned maintenance and repair of old pipelines is imperative. However, due to the complexity of underground pipe networks, repairs are easily affected by residential buildings and other facilities, making repairs difficult. Therefore, trenchless repair methods are needed. However, existing underground pipe networks often have small diameters, making it difficult for construction personnel to enter the pipes. Currently, trenchless pipe repair machines are commonly used. These machines typically involve attaching a flexible hose to an airbag, applying epoxy resin adhesive to the hose's outer surface, inserting the airbag into the pipe, inflating it to expand the hose and adhere it to the inner wall of the pipe, and then removing the airbag after the epoxy resin has hardened, thus repairing the pipeline.

[0003] When using this method for repair, the water flow in the pipe network needs to be shut off to allow the epoxy resin adhesive to solidify. However, shutting off the water flow will affect the normal use of the pipes by residents, which is very inconvenient.

[0004] Therefore, there is a need for a trenchless pipeline repair epoxy resin adhesive injection device and method to solve the above problems. Summary of the Invention

[0013] Preferably, a cleaning mechanism is provided on the side of the glue-filling mechanism away from the sealing mechanism.

[0019] This invention also provides a method for injecting epoxy resin adhesive for trenchless pipeline repair, comprising the following steps:

[0020] S1. Blocking; The pipe is separated by the blocking mechanism, and the pipe is divided into a flow area and a working area by the cylinder. That is, the through hole inside the cylinder is the flow area, and the outer circumferential side of the cylinder and the inner wall of the pipe form the working area.

[0021] S2. Pre-treatment: The inner wall of the pipe is pre-treated by a cleaning mechanism to facilitate the fitting of the repair hose.

[0022] S3. Applying epoxy resin to the repair hose using the epoxy resin application mechanism.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The sealing mechanism allows the equipment to seal the outer circumference of the cylinder with the inner wall of the pipe by expanding the sealing airbag during operation, forming a working area to facilitate repair work while ensuring water flow in the pipe and preventing the repair work from affecting residents' normal water supply. Simultaneously, the glue-applying mechanism allows epoxy resin to be squeezed onto the outer circumference of the repair hose after the working area is formed, ensuring even application. Furthermore, the protective cylinder protects the repair hose during the equipment's movement within the pipe, preventing damage from contaminants on the inner wall of the pipe.

[0025] 2. The design of the water-absorbing component enhances the water-proofing effect of the sealing airbag on the work area, preventing water from entering the work area through the gap between the sealing airbag and the inner wall of the pipe, thus affecting the repair effect of the repair hose.

[0026] 3. By designing the telescopic component, the sponge block is brought closer to the extrusion plate during the water-squeezing process after the water-absorbing component absorbs water, resulting in more thorough squeezing of the sponge block by the extrusion plate and improving the water-squeezing effect.

[0027] 4. The second motion mechanism can drive the cleaning mechanism to grind the inner wall of the pipe. During the grinding process, the friction pad can disengage from the inner wall of the pipe and use the flushing water inside the pipe to remove dirt from the friction pad, which facilitates subsequent grinding and improves the grinding effect.

[0054] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0055] like Figure 1-14As shown in the figure, an embodiment of the present invention discloses an epoxy resin adhesive injection device for trenchless pipeline repair, including a cylinder 1. A traveling mechanism 2 is provided at both ends of the cylinder 1. A sealing mechanism 3 is provided at one end of the cylinder 1. An adhesive injection mechanism 4 is sleeved at the other end of the cylinder 1. A partition mechanism 100 is provided on the side of the adhesive injection mechanism 4 away from the sealing mechanism 3. The sealing mechanism 3, the adhesive injection mechanism 4, and the partition mechanism 100 are all connected to the air source mechanism 5.

[0056] The sealing mechanism 3 includes a mounting plate 31 sleeved on the cylinder 1. The mounting plate 31 has an opening in a mounting cavity 32 facing away from the axis of the cylinder 1. A sealing airbag 33 is provided in the mounting cavity 32. The sealing airbag 33 is connected to the air source mechanism 5.

[0057] The glue-filling mechanism 4 includes a protective cylinder 41 that is fitted onto the cylinder 1 with a gap. A repair hose 6 is located between the protective cylinder 41 and the cylinder 1. The protective cylinder 41 can reciprocate linearly along the axis of the cylinder 1. The protective cylinder 41 has an opening facing away from the sealing mechanism 3 in the glue cavity 42. A glue-filling ring 43 is slidably connected in the glue cavity 42. The glue-filling ring 43 is fixedly connected to the cylinder 1. At least eight openings are evenly provided in the glue cavity 42 along the circumferential direction, facing the glue outlet 44 close to the cylinder 1. A fixing ring 45 is fixedly connected to one end of the protective cylinder 41 close to the sealing mechanism 3. At least eight glue-applying blocks 46 are evenly fixedly provided on the inner wall of the fixing ring 45 along the circumferential direction. The protective cylinder 41 is connected to a rotating component 47, which can drive the protective cylinder 41 to reciprocate along the axis of the cylinder 1.

[0058] The cylinder 1 includes a first cylinder 11 and a second cylinder 12, and the first cylinder 11 and the second cylinder 12 are detachably connected.

[0059] Specifically, during use, the traveling mechanism 2, located near the sealing mechanism 3, is inserted into the pipeline. The device is then pushed into the pipeline. When it reaches the area requiring repair, the device is positioned so that the repair hose 6 is directly opposite the repair area. Gas is then injected into the sealing airbag 33 via the air source mechanism 5, causing the airbag 33 to inflate and seal the outer circumference of the cylinder 1 against the inner wall of the pipeline. Simultaneously, the isolation mechanism 100 is inflated, sealing the outer circumference of the cylinder 1 against the inner wall of the pipeline, forming a working area. This allows water to flow from the cylinder... The internal passage of 1 prevents water from flowing through the working area, facilitating repair work. Then, the glue-filling mechanism 4 is activated, and the protective cylinder 41 moves away from the sealing mechanism 3, causing the glue-filling ring 43 to squeeze the epoxy resin glue in the glue cavity 42 from the glue outlet 44 onto the outer surface of the repair hose 6. During the movement of the protective cylinder 41, the rotating part 47 drives the protective cylinder 41 to rotate. The protective cylinder 41 drives the glue-applying block 46 to move through the fixing ring 45. The glue-applying block 46 spreads the squeezed glue evenly on the repair hose 6.

[0060] By setting up the sealing mechanism 3, the equipment can seal the outer circumference of the cylinder 1 with the inner wall of the pipe through the expansion of the sealing airbag 33 during operation, forming a working area to facilitate the equipment's repair work. At the same time, it ensures the flow of water in the pipe and avoids affecting the normal water supply of residents during the repair work. Meanwhile, by setting up the glue-filling mechanism 4, after the working area is formed, epoxy resin can be squeezed onto the outer circumference of the repair hose and spread evenly. At the same time, during the movement of the equipment in the pipe, the protective cylinder 41 protects the repair hose and prevents dirt and other contaminants on the inner wall of the pipe from damaging the repair hose during the movement.

[0061] Furthermore, a camera is installed on the traveling mechanism 2 near the glue dispensing mechanism 4, and the camera is electrically connected to the external control system.

[0062] Specifically, during use, the camera observes the damage to the inner wall of the pipe while the equipment is in motion.

[0063] Furthermore, the rotating component 47 includes a wave-shaped slide rail 471 fixedly connected to the cylinder 1, and a sliding pin 472 is slidably connected in the wave-shaped slide rail 471, and the sliding pin 472 is fixedly connected to the protective cylinder 41.

[0064] Specifically, when the protective cylinder 41 moves, it causes the sliding pin 472 to slide in the slide rail 471. Since the slide rail 471 is wavy, the protective cylinder 41 rotates, thereby spreading the glue evenly.

[0065] Furthermore, the protective cylinder 41 is connected to a movable component 48, which includes a second electromagnetic slide rail 481 fixedly mounted on the cylinder 1, a second electromagnetic slider 482 slidably connected in the second electromagnetic slide rail 481, and a movable ring 483 rotatably mounted on the protective cylinder 41, which is fixedly connected to the second electromagnetic slider 482.

[0066] Specifically, when the protective cylinder 41 needs to move, the second electromagnetic slider 482 is activated. The second electromagnetic slider 482 slides in the second electromagnetic slide rail 481. The second electromagnetic slider 482 drives the moving ring 483 to move, and the moving ring 483 drives the protective cylinder 41 to move. At the same time, the protective cylinder 41 rotates relative to the moving ring 483 under the action of the rotating component 47.

[0067] Furthermore, the glue-filling ring 43 is fixedly connected to the cylinder 1 via the connecting rod 49.

[0068] Furthermore, the sealing mechanism 3 also includes a water-absorbing component 34, which is mounted on a first motion mechanism 7. The first motion mechanism 7 can drive the water-absorbing component 34 to rotate along the axis of the cylinder 1. The water-absorbing component 34 includes a mounting shaft 341, on which a sponge block 342 is rotatably sleeved. The cylinder 1 has an upward-facing water outlet 343, which is connected to a water collection tank 344 located in the cylinder 1. Two first electromagnetic sliding grooves 345 are symmetrically fixedly connected on both sides of the water outlet 343. An electromagnetic slider 346 is slidably mounted in each first electromagnetic sliding groove 345, and a squeezing plate 347 is fixedly connected to each electromagnetic slider 346. The sponge block 342 can move between the two squeezing plates 347.

[0069] Furthermore, the mounting shaft 341 is located slightly above the center of the sponge block 342.

[0070] Specifically, after the sealing airbag 33 inflates, the first motion mechanism 7 is activated, causing the first motion mechanism 7 to drive the sponge block 342 to rotate. During the rotation, the sponge block 342 abuts against the bottom of the inner wall of the pipe, absorbing the water remaining in the working area and the water that seeps into the working area between the sealing airbag 33 and the inner wall of the pipe. When the sponge block 342 moves between the two extrusion plates 347, the first motion mechanism 7 is stopped, and then the first electromagnetic slider 346 is activated, causing the first electromagnetic slider 346 to slide in the first electromagnetic groove 345, bringing the two extrusion plates 347 closer to each other. The two extrusion plates 347 squeeze the water in the sponge block 342 into the water outlet 343, and the squeezed water enters the water collection tank 344.

[0071] By setting up the water-absorbing component 34, the sealing airbag 33 can better isolate water in the working area, preventing water from entering the working area through the gap between the sealing airbag 33 and the inner wall of the pipe, thus affecting the repair effect of the repair hose 6.

[0072] Furthermore, the first motion mechanism 7 is disposed between the glue-filling mechanism 4 and the sealing mechanism 3. The first motion mechanism 7 includes two mounting rings 71 fixedly sleeved on the cylinder 1. At least two motors 72 are uniformly fixedly connected to one of the mounting rings 71 along the circumferential direction. A gear 73 is fixedly connected to the output end of the motor 72. A toothed ring 74 is fitted on the cylinder 1 with a gap. The gear 73 meshes with the toothed ring 74. An mounting cylinder 75 is fixedly connected to the outer circumferential side of the toothed ring 74. Two telescopic members 76 are uniformly fixedly connected to the mounting cylinder 75 along the circumferential direction. The telescopic members 76 are connected to the water-absorbing member 34.

[0073] Specifically, when the first motion mechanism 7 needs to drive the water suction component 34 to rotate, the motor 72 is started. The motor 72 drives the gear 73 to rotate, the gear 73 drives the gear ring 74 to rotate, the gear ring 74 drives the mounting cylinder 75 to rotate, and the mounting cylinder 75 drives the water suction component 34 to rotate through the telescopic component 76.

[0074] Furthermore, the telescopic component 76 includes a fixed cylinder 761 fixedly connected to the mounting cylinder 75, a telescopic rod 762 slidably connected in the fixed cylinder 761, a first spring 763 connected between the telescopic rod 762 and the mounting cylinder 75, a spring groove 764 with its opening direction away from the axis of the cylinder 1 opened in the telescopic rod 762, an extension rod 765 slidably connected in the spring groove 764, a second spring 766 connected between the extension rod 765 and the spring groove 764, and the extension rod 765 and the mounting shaft 341... The fixed connection includes a groove 767 in the fixed cylinder 761 with its opening direction along the axis of the cylinder 1. An abutment rod 768 is fixedly connected to the telescopic rod 762, and the abutment rod 768 extends out of the groove 767. The openings of the two grooves 767 in the two telescopic members 96 are opposite. An abutment ring 769 is fixedly connected to each mounting ring 71. The top of the abutment ring 769 has a notch, and the two ends of the notch are chamfered. The two abutment rods 768 in the two telescopic members 76 are respectively located at the two notches.

[0075] Specifically, during use, when the equipment moves in the pipeline, the planes where the two telescopic components 76 are located are parallel to the horizontal plane. At this time, due to the abutment action between the abutment rod 768 and the outer circumferential side of the abutment ring 769, the abutment rod 768 drives the telescopic rod 762 to stretch the first spring 763 out of the fixed cylinder 761. When the water suction component 34 needs to work, the motor 72 is started, causing the telescopic component 76 to rotate. When the abutment rod 768 moves to the notch position on the abutment ring 769, the abutment rod 768 disengages from the abutment ring 769, and at the same time, the telescopic rod 762 retracts into the fixed cylinder 761, making the sponge block 342 closer to the extrusion plate 347.

[0076] By setting the telescopic component 76, the water-absorbing component 34 makes the sponge block 342 closer to the extrusion plate 347 during the water-squeezing process after absorbing water, so that the extrusion plate 347 squeezes the sponge block 342 more thoroughly and improves the water-squeezing effect.

[0077] Furthermore, a cleaning mechanism 8 is provided on the side of the glue-filling mechanism 4 away from the sealing mechanism 3. The cleaning mechanism 8 is mounted on the second motion mechanism 9. The second motion mechanism 9 can drive the cleaning mechanism 8 to rotate along the axis of the cylinder 1. The cleaning mechanism 8 includes an arc-shaped mounting plate 81. A friction tile 82 is fixedly connected to the side of the mounting plate 81 away from the cylinder 1.

[0078] Specifically, when the equipment is moved to the part of the pipeline to be repaired, the friction pad 82 is first positioned facing the part to be repaired, and then the second motion mechanism 9 is activated, which drives the cleaning mechanism 8 to rotate, and the friction pad 82 performs preliminary grinding treatment on the part to be repaired.

[0079] The cleaning mechanism 8 allows the area to be polished before repair, facilitating the repair work.

[0080] Furthermore, the second motion mechanism 9 has the same structure as the first motion mechanism 7. The included angle between the two notches in the two abutment rings 769 in the second motion mechanism 9 is 180°. Cleaning mechanisms 8 are fixedly connected to the two extension rods 765 in the second motion mechanism 9 respectively.

[0081] Specifically, when the equipment moves in the pipeline, the abutment rods 768 in the two telescopic components 76 are respectively located in the notches of the two abutment rings 769, which shortens the extension distance of the telescopic rod 762 and prevents the friction pad 82 from abutting against the inner wall of the pipeline during the movement of the equipment; when the friction pad 82 needs to rotate, the second motion mechanism 9 is activated, and the abutment rod 768 abuts against the outer circumferential side wall of the abutment ring 769, so that the telescopic rod 762 extends out of the fixed cylinder 761, and the friction pad 82 abuts against the inner wall of the pipeline. The inner wall of the pipe is polished. When the abutment rod 768 moves to the notch of the abutment ring 769, the telescopic rod 762 retracts into the fixed cylinder 761, causing the friction tile 82 to disengage from the inner wall of the pipe. Then, under the flushing action of the water flow, the dirt adhering to the friction tile 82 is washed off. After that, the abutment rod 768 and the abutment ring 769 re-abut each other. After being flushed, the friction tile 82 polishes the inner wall of the pipe again. After the polishing is completed, the second motion mechanism 9 is stopped and the sealing mechanism 3 is started.

[0082] The second motion mechanism 9 enables the cleaning mechanism 8 to grind the inner wall of the pipe. During the grinding process, the friction pad 82 can disengage from the inner wall of the pipe and use the flushing water inside the pipe to remove dirt from the friction pad 82, which facilitates subsequent grinding and improves the grinding effect.

[0083] Furthermore, the partition mechanism 100 includes a partition plate 101 sleeved on the cylinder 1, the partition plate 101 having an opening facing away from the axis of the cylinder 1, the partition cavity 102 being provided with a partition airbag 103, and the partition airbag 103 being connected to the air source mechanism 5.

[0084] Specifically, during use, when the sealing mechanism 3 is inflated, the gas source mechanism 5 fills the isolation airbag 103 with gas, causing the isolation airbag 103 to expand and seal the outer circumferential side of the cylinder 1 with the inner wall of the pipe.

[0085] Furthermore, an airbag 10 is fixedly sleeved on the cylinder 1, the airbag 10 is connected to the air source mechanism 5, and the repair hose 6 is sleeved on the airbag 10.

[0086] Specifically, after the glue-applying mechanism 4 applies glue to the repair hose 6, the air source mechanism 5 inflates the air bag 10, causing the air bag 10 to expand the repair hose 6 and adhere it to the inner wall of the pipe, thus completing the repair work.

[0087] Furthermore, the traveling mechanism 2 includes a mounting fork 21 fixedly connected to the end of the cylinder 1. A mounting rod 22 is fixedly connected to the mounting fork 21. Three hinge rods 23 are evenly hinged along the circumferential direction on the mounting rod 22. A traveling wheel 24 is rotatably provided at the end of each hinge rod 23 away from the hinge end. A sliding ring 25 is slidably sleeved on the mounting rod 22. Three support rods 26 are evenly hinged along the circumferential direction on the sliding ring 25. Each support rod 26 is hinged to the hinge rod 23. A sliding cavity 27 is formed in the mounting rod 22. Three communicating grooves 28 communicating with the outside are evenly formed along the circumferential direction on the inner wall of the sliding cavity 27. A linkage block 29 is slidably arranged in the sliding cavity 27. The linkage block 29 is fixedly connected to the sliding ring 25. A third spring is connected between the linkage block 29 and the sliding cavity 27.

[0088] Specifically, the traveling mechanism 2 is placed in the pipe. Depending on the pipe diameter, the inner wall of the pipe causes the traveling wheel 24 to move closer to or further away from the mounting rod 22. The traveling wheel 24 drives the hinge rod 23 to rotate, the hinge rod 23 drives the support rod 26 to rotate, and the support rod 26 drives the linkage block 29 to stretch the third spring to different degrees.

[0089] The travel mechanism 2 enables the equipment to travel in pipes of different diameters.

[0090] Furthermore, the air source mechanism 5 includes an air pipe 51 that passes through one of the mounting rods 22. One end of the air pipe 51 is connected to an external air source, and the other end of the air pipe 51 extends into the cylinder 1. A first air box 52 is connected to the end of the air pipe 51. The first air box 52 is connected to the sealing airbag 33 through a first connecting pipe 53. A second air box 55 is connected to the first air box 52 through a second connecting pipe 54. An electromagnetic on / off valve is installed in the second connecting pipe 54. The second air box 52 is connected to the airbag 10 through a third connecting pipe 56. The second air box 55 is connected to the isolation airbag 103 through a fourth connecting pipe 57. An electromagnetic three-way valve is installed in the second air box 55.

[0091] Specifically, when the sealing airbag 33 needs to be inflated, the external air source inflates the first air box 52 through the air pipe 51. At this time, the electromagnetic on / off valve is closed, and the gas enters the sealing airbag 33 through the first connecting pipe 53. After the sealing airbag 33 is fully inflated, the electromagnetic on / off valve is opened, and the gas enters the isolation airbag 103 through the air pipe 53, the first air box 52, the second connecting pipe 54, the electromagnetic three-way valve, and the fourth connecting pipe 57. When the airbag 10 needs to be inflated, the air pressure of the external air source is increased, the electromagnetic three-way valve is opened, and the gas enters the airbag 10 through the third connecting pipe 56.
