Description
Technical Field
[0001] The invention relates to the technical field of pipeline repair, in particular to an ultraviolet light in-situ curing repair hose with a waterproof outer film. Background Art
[0002] UV-CIPP is a highly effective pipe repair technology that uses hoses made of special materials to repair pipes in areas that require rapid repairs and are difficult to repair with traditional excavation, such as in city centers, under busy roads, or in ecologically sensitive areas.
[0003] The hose is usually made of fiberglass fabric and is pre-impregnated with a light-curing resin. The resin-impregnated hose is then pulled into the original pipe, inflated to expand it and fit tightly against the original pipe. The hose is then irradiated with ultraviolet light to cure it inside the pipe, forming a new lining layer, thereby repairing the pipe.
[0004] However, in actual use, when the impregnated hose is pulled into the original pipeline, a roller drive belt without limit baffles on both sides is laid on the ground. When the resin-impregnated hose is pulled and moved, the staff mostly relies on manually correcting the hose position to ensure that the hose does not fall directly to the ground. The hose has weight and a certain inertia when moving. In case of emergency, such as machine failure, misalignment of the inserted hose, etc., it is necessary to stop pulling and make adjustments. At this time, the repair hose end stops moving, and the repair hose on the roller drive belt will continue to move into the pipeline under the action of inertia. This can easily cause excess hose stacking or bending at the pipeline inlet, causing overall damage to the hose, thereby affecting the progress of subsequent inflation and curing of the hose.
[0005] Therefore, the present application provides a UV light in-situ curing repair hose with a waterproof outer film to meet the needs. Summary of the invention
[0006] The technical problem to be solved by the present invention is to provide a UV in-situ curing repair hose with a waterproof outer film to solve the problem that the end of the existing repair hose stops moving, while the repair hose on the roller drive belt continues to move into the pipeline under the action of inertia, which easily causes excess hose stacking or bending at the pipeline inlet, causing damage to the entire hose.
[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0008] A UV in-situ curing repair hose with a waterproof outer film comprises a repair hose, wherein an L-shaped guide clamp tube is slidably connected to the surface of the repair hose, a clamp pad is installed at the bottom end of the repair hose, a U-shaped clamp plate is installed on the top of the L-shaped guide clamp tube, a reinforcing portion is fixedly connected to the bent end of the L-shaped guide clamp tube, and a fixing nail is fixedly installed at the bottom of the L-shaped guide clamp tube; a limit clamping assembly, wherein the limit clamping assembly is used to prevent the repair hose from continuing to move due to inertia after pulling is completed, and the limit clamping assembly is connected to the L-shaped guide clamp tube.
[0009] Optionally, the limiting clamping assembly includes an arc-shaped support frame fixedly connected to the inner cavity of the L-shaped guide clamp tube, a curved pressure plate is fixedly connected to the middle of the arc-shaped support frame, a first weakening groove is provided in the middle of the arc-shaped support frame, and a C-shaped limiting clamp is fixedly connected to the middle of the arc-shaped support frame.
[0010] Optionally, a second weakened groove is provided at the top of the C-shaped limiting clamp, and an extension portion is provided in the middle of the arc-shaped supporting frame.
[0011] Optionally, a roller is fixedly connected to the end of the arc-shaped support frame, and a stress-bearing bent plate is attached to the middle of the arc-shaped support frame.
[0012] Optionally, a sliding column is fixedly connected to the bottom end of the stress-bent plate, an elastic sheet is fixedly connected to the bottom end of the extension portion, and a pressing disc is fixedly connected to the bottom of the elastic sheet.
[0013] Optionally, the bottom end of the curved pressure plate is attached to the top of the C-shaped limiting clamp, and the surface of the C-shaped limiting clamp is attached to both ends of the repair hose.
[0014] Optionally, the top of the stress-bent plate fits in the inner cavity of the extension portion, and the bottom of the pressing disc fits in the top of the repair hose.
[0015] Optionally, the width of the middle portion of the U-shaped clamping plate is smaller than the width of the middle portion of the L-shaped guide clamping tube, and a weakened point is provided at the end of the inner cavity of the L-shaped guide clamping tube for downward inclination of the curved end of the L-shaped guide clamping tube.
[0016] Optionally, the bending pressure plate is located outside the arc-shaped support frame and fits with the top of the C-shaped limit clamp when bent, and the arc-shaped support frame and the C-shaped limit clamp are both made of hollow plastic material.
[0017] Optionally, the elastic sheet is C-shaped, the pressing disc is made of rubber, and the sliding columns are arranged in a linear array along the moving direction of the repair hose.
[0018] Compared with the prior art, the present invention has at least the following beneficial effects:
[0019] In the above scheme, by setting a limit clamping component, the repair hose can be limited first when the repair hose is placed into the L-shaped guide clamp tube, and the two ends of the repair hose can be automatically adapted and clamped according to the diameter of the repair hose, so that the direction of the repair hose is limited in the initial state, avoiding the situation where workers manually correct the position when being pulled. When an emergency occurs, the upper end of the arc-shaped support frame will be deformed under pressure, and the bent pressure plate at this time will be displaced and conflict with the top of the C-shaped limit clamp. Under the action of pressure, the C-shaped limit clamp can be better fitted to the two ends of the repair hose. At this time, the friction between the two is increased, which is convenient for better limiting the movement of the repair hose and preventing the hose from entering the pipeline and stacking, causing the hose to bend and damaged, thereby ensuring the normal progress of the subsequent inflation and curing hose.
[0020] By arranging the stress-bent plate, the sliding column, the elastic sheet and the pressing disc, in an emergency, the repair hose stops being pulled, and the speed of the repair hose will be limited and reduced by the limit clamping assembly. After the inner cavity of the extension part is compressed, it will be squeezed and contacted with the stress-bent plate, and the sliding column will drive the pressing disc to move downward under the action of pressure. At this time, the elastic sheet will be straightened, and the pressing disc will contact the waterproof outer film on the surface of the repair hose, and increase the friction between the pressing disc and the outer mold of the repair hose, further reducing the speed of the repair hose under inertia, thereby assisting the limit clamping assembly to limit the repair hose and improving the clamping and limiting effect of the repair hose.
[0021] By providing an L-shaped guide clamp and a reinforcement part, when the repair hose is no longer towed, the weight of the repair hose will continue to move due to inertia. At this time, the worker manually presses the bent end of the L-shaped guide clamp so that the bottom of the bent end is in direct contact with the top of the repair hose. At this time, in order to increase the contact area between the bent end of the L-shaped guide clamp and the top of the repair hose, the thickening effect of the reinforcement part enables the bent end of the L-shaped guide clamp to be pressed while ensuring the strength of the bent end of the L-shaped guide clamp and providing a preliminary limit to the repair hose, thereby reducing the speed of the repair hose after inertia and preventing the repair hose from falling and stacking inside the original pipeline, causing bending and damage to the repair hose.

[0039] like Figures 1 to 8As shown, an embodiment of the present invention provides a UV in-situ curing repair hose with a waterproof outer film, comprising a repair hose 1, wherein the surface of the repair hose 1 is slidably connected with an L-shaped guide clamping tube 2, a clamping pad 3 is installed at the bottom end of the repair hose 1, a U-shaped clamping plate 4 is installed on the top of the L-shaped guide clamping tube 2, a reinforcing portion 5 is fixedly connected to the bent end of the L-shaped guide clamping tube 2, and a fixing nail is fixedly installed at the bottom of the L-shaped guide clamping tube 2; a limit clamping assembly, the limit clamping assembly is used to prevent the repair hose 1 from continuing to move due to inertia after the pulling is completed, the limit clamping assembly is connected to the L-shaped guide clamping tube 2, the limit clamping assembly includes an arc-shaped support frame 6 fixedly connected to the inner cavity of the L-shaped guide clamping tube 2, the end of the arc-shaped support frame 6 is fixedly connected to a roller 7, the middle of the arc-shaped support frame 6 is fitted with a stress-bent plate 8, and the L-shaped guide clamping tube The shape of 2 is L-shaped, and the L-shaped guide clamp tube 2 exposed outside the ground is longer, while the L-shaped guide clamp tube 2 deep into the pipeline is shorter. Combined with the fixing nails at the bottom of the L-shaped guide clamp tube 2, the staff will place the L-shaped guide clamp tube 2 as a whole at the outlet of the pipeline, and the fixing nails will contact and fix on the ground and the pipe wall of the pipeline outlet respectively. Slightly shake to check whether the L-shaped guide clamp tube 2 is stable, then fix the end of the repair hose 1 with the clamp pad 3 and tie it with the traction rope of the winch, put the end of the repair hose 1 horizontally from the L long end of the L-shaped guide clamp tube 2, and press it on the roller 7, then start the winch to drive the repair hose 1 to move along the shape trajectory of the L-shaped guide clamp tube 2, ensure that the repair hose 1 is smoother when it is stretched and moved, and cooperate with the rolling of the roller 7 to more conveniently send the repair hose 1 into the original pipeline.
[0040] By setting the U-shaped clamping plate 4, the U-shaped clamping plate 4 is clamped in the middle position of the L-shaped guiding clamping tube 2. In the initial state, the bent end of the L-shaped guiding clamping tube 2 is flat. When encountering an emergency, the worker manually presses the bent end of the L-shaped guiding clamping tube 2, which will cause the bent end of the L-shaped guiding clamping tube 2 to deform and move closer to the middle. At this time, the distance between the bent ends is reduced. When the bent ends fit each other, the U-shaped clamping plate 4 is directly placed in the middle of the L-shaped guiding clamping tube 2, and then the pressing of the bent end of the L-shaped guiding clamping tube 2 is cancelled, which will automatically rebound. When the bent ends of the L-shaped guiding clamping tube 2 and the U-shaped clamping plate 4 fit each other, the rebound effect is minimized so that they are clamped to each other. This method is more laborious when pressing the L-shaped guiding clamping tube 2, but is easier when clamping the U-shaped clamping plate 4, which is convenient for quick The repair hose 1 is limited in position, which is suitable for situations where precise positioning of the repair pipeline is required and the outer film of the repair hose has good friction resistance. When there is a small distance between the bent ends, the U-shaped clamp 4 can be clamped in advance from the inlet end of the L-shaped guide clamp tube 2, and the bent end of the L-shaped guide clamp tube 2 is continuously pressed down until the distance between the bent ends of the L-shaped guide clamp tube 2 after being pressed down is consistent with the distance between the bent ends of the U-shaped clamp 4, the top of the U-shaped clamp 4 is held and the U-shaped clamp 4 is slid in along the trajectory of the bent end. This method is suitable for situations where the repair hose is constantly correcting its position when entering the pipeline. By slow movement and mutual cooperation, the front end and middle part of the repair hose 1 will not be accumulated or bent and deformed, thereby avoiding affecting the subsequent normal use of the repair hose 1.
[0041] like Figure 6 to Figure 7 As shown, a curved pressure plate 601 is fixedly connected to the middle of the arc-shaped support frame 6, a first weakened groove 602 is provided in the middle of the arc-shaped support frame 6, a C-shaped limit clamp 603 is fixedly connected to the middle of the arc-shaped support frame 6, a second weakened groove 604 is provided on the top of the C-shaped limit clamp 603, an extension portion 605 is provided in the middle of the arc-shaped support frame 6, the curved pressure plate 601 is fixed to the side of the arc-shaped support frame 6, and is inclined to extend downward. When the L-shaped guide clamp tube 2 is pressed, the L-shaped guide clamp tube 2 will tilt downward under the action of pressure. Under the action of the first weakened groove 602, the contact surface between the top of the arc-shaped support frame 6 and the top of the inner cavity of the L-shaped guide clamp tube 2 will be compressed, and the bent pressure plate 601 will also tilt downward under the compression of the top of the arc-shaped support frame 6, and contact and rub with the two ends of the repair hose 1 during the tilt. On the one hand, it can block and scrape away impurities adhered to the two ends of the repair hose 1 during the movement, and on the other hand, it can increase the direct friction between the end of the bent pressure plate 601 and the two ends of the repair hose 1, further limiting the clamping of the repair hose 1.
[0042] The C-shaped limit clamp 603 is fixed in the downward position in the middle of the arc-shaped support frame 6, and also protrudes a certain length. When the repair hose 1 is placed in the inlet of the L-shaped guide clamp tube 2, the two ends of the repair hose 1 will first fit on the inner wall of the C-shaped limit clamp 603, and with the second weakened groove 604, it can adapt to repair hoses 1 of different diameters. When the large diameter is placed on the inner wall of the C-shaped limit clamp 603, the C-shaped limit clamp 603 will be stretched open. At this time, the second weakened groove 604 will be squeezed by the C-shaped limit clamp 603 to deform and compress, and between the C-shaped limit clamp 603 and the repair hose 1, the second weakened groove 604 will be squeezed open by the C-shaped limit clamp 603. When the tubes 1 are squeezed against each other, an interaction force will be formed, and the clamping of the C-type limit clamp 603 is not completely locked. It will rebound back and forth under the compression of the second weakened groove 604. This effect can prevent the outer membrane of the repair hose 1 from being seriously scratched or even worn due to excessive friction on both sides when the repair hose 1 is pulled deeper into the original pipeline. In addition, the C-type limit clamp 603 in the initial state plays a limiting role, which can ensure that the repair hose 1 remains on the motion trajectory when moving, thereby improving the smoothness of the overall work and the limiting clamping of the repair hose 1.
[0043] When the curved support frame 6 is compressed and tilted downward, the bottom end of the curved pressure plate 601 will contact the top of the C-shaped limit clamp 603, so that the stability of the C-shaped limit clamp 603 is improved, thereby improving the clamping effect of the repair hose 1, increasing the friction between the inner wall of the C-shaped limit clamp 603 and the two ends of the repair hose 1, and facilitating the repair hose 1 to better reduce its speed in the L-shaped guide clamp tube 2. After the second weakened groove 604 is compressed, the width of the top of the C-shaped limit clamp 603 becomes smaller. Since the curved pressure plate 601 is tilted and fixed on the side of the curved support frame 6, the contact area with the top of the C-shaped limit clamp 603 is larger when it descends, so that when the second weakened groove 604 is completely compressed, the bottom end of the curved pressure plate 601 can still be in contact, avoiding the situation that when the diameter of the repair hose 1 is too large, the downward inclination of the curved pressure plate 601 cannot contact the top of the C-shaped limit clamp 603, thereby improving the clamping and limiting effect of the repair hose 1.
[0044] like Figure 8As shown, the bottom end of the stress-bent plate 8 is fixedly connected with a sliding column 801, the bottom end of the extension 605 is fixedly connected with an elastic sheet 802, and the bottom of the elastic sheet 802 is fixedly connected with a pressing disc 803. The stress-bent plate 8 is made of rubber and is curved. When the L-shaped guide clamping tube 2 is pressed, the L-shaped guide clamping tube 2 as a whole will be compressed and deformed, and the extension 605 will be compressed. At this time, the stress-bent plate 8 will contact the compressed extension 605 and continuously press the extension 605 during the compression process. The stress-bent plate 8 is squeezed, so that the sliding column 801 and the pressing disc 803 are displaced downward, and the elastic sheet 802 is gradually straightened when the sliding column 801 is displaced downward. Since the main shaking of the sliding column 801 and the pressing disc 803 in the initial state is mainly due to the rebound of the elastic sheet 802, when the stress-bent plate 8 is not squeezed, the pressing disc 803 is close to the bottom end of the extension part 605. This description is intended to make it clear that when the repair hose 1 moves inside the L-shaped guide clamp tube 2 The top of the repair hose 1 is not firmly attached to the top of the repair hose 1 because the elastic effect of the elastic sheet 802 makes the pressing disc 803 and the top of the repair hose 1 generally not fit tightly to the top of the repair hose 1. Its function is to prevent the outer membrane of the repair hose 1 from being scratched by directly sticking to the surface of the repair hose 1, causing the repair hose 1 to be unable to be used normally later. A certain fitting effect can further improve the limiting effect on the repair hose 1, enhance the braking effect of the repair hose 1 after the traction stops, and reduce the occurrence of stacking or bending of the repair hose 1 in the original pipeline. After the bending end of the L-shaped guide clamp tube 2 stops pressing, the arc support frame 6 is no longer compressed as a whole, so that the force-bearing bent plate 8 is no longer pressed by the extension portion 605, and under the rebound of the elastic sheet 802, the sliding column 801 and the pressing disc 803 will return to their initial state.
[0045] The workflow of the technical solution provided by the present invention is as follows:
[0046] Before repairing a damaged pipeline, first open the manhole cover, use a survey robot to check the inside of the pipeline, and use relevant equipment to remove dirt and impurities on the inner wall of the pipeline. Then lay the outer membrane and lay it from the inlet to the outlet using a winch or other traction equipment.
[0047] After the preliminary work is done, start to place the L-shaped guide clamp tube 2, fit the short end of the L-shaped guide clamp tube 2 to the inner wall of the pipe, and place the long end directly on the ground. Use the fixing nails to increase the stability of the L-shaped guide clamp tube 2. After slightly shaking the L-shaped guide clamp tube 2 to ensure that it is in a stable state, start to manually pull out the end of the repair hose 1, and clamp the clamp pad 3 to fix it on the end of the repair hose 1, and tie the traction rope of the winch firmly to the clamp pad 3. Then put the end of the repair hose 1 into the middle of the port of the L-shaped guide clamp tube 2, and first place one end of the repair hose 1 in the On the C-shaped limit clamp 603, the middle part of the repair hose 1 is placed on the roller 7, and the other end of the repair hose 1 is placed on another C-shaped limit clamp 603. When placed, the second weakened groove 604 will be compressed to varying degrees according to the width of the repair hose 1. At this time, only the end of the repair hose 1 enters the L-shaped guide clamp tube 2, and the rest of the repair hose is still outside. It has great instability and requires workers to support it on both sides. When the winch pulls the end of the repair hose 1 into the pipeline, the supporting workers can let go and cooperate with other workers.
[0048] During the transportation work, if there is no emergency, the repair hose 1 is normally transported into the pipeline by the winch. If an emergency occurs, whether it is equipment failure or the repair hose 1 is misaligned during transportation, the work of the winch traction equipment must be stopped first. The repair hose 1 has a certain weight. Under the rolling action of the roller 7 inside the L-shaped guide clamp tube 2, the repair hose 1 has a certain inertia, so that the position of the end of the repair hose 1 stops moving, while the repair hose 1 inside the L-shaped guide clamp tube 2 is still transported into the pipeline. This causes the repair hose 1 that has just entered the pipeline to be stacked or bent. At this time, the worker needs to press the middle bent end of the repair hose 1. After being pressed, the bent end will move toward the middle, and the U-shaped clamp 4 can be taken at any hollow position to clamp the bent end of the U-shaped clamp 4 with the bent end of the L-shaped guide clamp tube 2. At this time, the bottom of the bent end of the L-shaped guide clamp tube 2 is in contact and friction with the top of the repair hose 1, which slows down the movement of the repair hose 1. The position of the reinforcement part 5 is relatively flat, which increases the contact area with the repair hose 1 and improves the speed reduction, which is a first-level limit.
[0049] It is worth mentioning that according to the working method of the workers and the specific material of the repair hose 1, two different methods can be used. One is that when the repair hose 1 is pulled and moved by the winch, the bent end of the L-shaped guide clamp tube 2 can be slowly pressed so that the bottom of the bent end gradually contacts with the repair hose 1, generating a certain friction, reducing the moving speed of the repair hose 1 inside the L-shaped guide clamp tube 2, and clamping the U-shaped clamp plate 4 at the front end of the L-shaped guide clamp tube 2, but not completely, so that during the entire transportation process, the bottom of the bent end of the L-shaped guide clamp tube 2 is always in contact with the top of the repair hose 1. This method requires first First, determine whether the outer film of the repair hose 1 can withstand a certain amount of friction. Second, when the repair hose 1 is pulled and moved by the winch, in an emergency, directly press the bent end of the L-shaped guide clamp 2 with force, and directly make the bottom of the bent end contact with the top of the repair hose 1. This can brake the repair hose 1 moving inside the L-shaped guide clamp 2 to the greatest extent, and then use the U-shaped clamp 4 to clamp it. Because the distance between the bent ends of the U-shaped clamp 4 in the initial state is much smaller than the distance between the L-shaped guide clamp 2 and the surface of the roller 7, there will be no unstable clamping of the small-diameter repair hose 1.
[0050] When the curved end of the L-shaped guide clamp tube 2 is pressed, the arc support frame 6 will bend as the L-shaped guide clamp tube 2 is pressed downward. At this time, the curved pressure plate 601 fixed on the side of the arc support frame 6 will tilt and contact with the two ends of the repair hose 1. On the one hand, it can block and clean the impurities adhering to the two ends of the repair hose 1, and on the other hand, it can increase the friction with the two ends of the repair hose 1. It is a secondary limit. When the curved pressure plate 601 tilts downward, its bottom end will contact and press with the top of the C-shaped limit clamp 603, so that the C-shaped limit clamp 603 and the end of the repair hose 1 have a better clamping effect, and when the second weakening groove 604 is fully compressed, the width of the top of the C-shaped limit clamp 603 can still contact with the bottom end of the curved pressure plate 601, so there will be no situation where the curved pressure plate 601 tilts downward and cannot touch the top of the C-shaped limit clamp 603.
[0051] At the same time, after pressing the curved end of the L-shaped guiding clamp tube 2, the arc-shaped support frame 6 will be compressed as a whole, and the compression of the extension part 605 will contact the stress-bent plate 8, so that the stress-bent plate 8 will move downward under the action of squeezing and drive the sliding column 801 and the pressing disc 803 to descend, and under continuous pressing, the pressing disc 803 will continue to approach the top of the repair hose 1 until it fits. At this time, the curved end of the L-shaped guiding clamp tube 2 is fixed by the U-shaped clamp plate 4, and there will be a slight shake under the action of the elastic sheet 802, which reduces friction. The outer membrane of the repair hose 1 is rubbed, but the pressing disc 803 will continue to contact the top of the repair hose 1, increasing the friction again, and the pressing disc 803 is linearly arrayed along the direction of the L-shaped guide clamp 2, and multiple pressing discs 803 act on the top of the repair hose 1 simultaneously, thereby reducing the speed of the repair hose 1 inside the L-shaped guide clamp 2. This is a three-level limit. At this time, under the joint action of multiple levels of limits, the repair hose 1 located inside the L-shaped guide clamp 2 will stop moving, achieving its clamping limit effect.
[0052] After the fault is eliminated, hold the U-shaped clamp 4 at the hollow position and slide the U-shaped clamp 4 out from the inlet end of the L-shaped guide clamp tube 2. At this time, the bent end of the L-shaped guide clamp tube 2 will return to its initial state, and the arc-shaped support frame 6 will also return to its initial state. The sliding column 801 and the pressing disc 803 will return to their initial state under the rebound force of the elastic sheet 802 without being pressed. Continue to start the winch and pull the repair hose 1 to move.
[0053] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.
