Description

Technical Field

[0001] The present invention relates to the technical field of light-curing lined hose processing, and in particular to a light-curing lined hose for trenchless pipeline repair, and a production device and a production process. Background Art

[0002] When processing the light-curing lined hose, it is necessary to go through the processes of unloading, folding, laminating, and collecting materials to produce a finished dry pipe. Then, the finished dry pipe is sealed, vacuumed, filled, and rolled to finally produce a usable light-curing lined hose. However, during filling, since the light-curing resin is a viscous material, it will inevitably bring in air, and these air bubbles will form large bubbles in it. During the subsequent curing, cavities will be generated, causing water leakage in the sewer pipe. In the existing technology, multiple rolling methods are often used to squeeze out large bubbles, but after the large bubbles are broken, they will generally turn into several medium bubbles, and cannot turn into small bubbles, resulting in the risk of water leakage.

[0003] If the resin inside the hose is kneaded before and during rolling, the bubbles can be squeezed and broken into tiny bubbles through repeated squeezing. These tiny bubbles will not cause cavitation and can flow out of the resin more easily. However, it is difficult to install a kneading mechanism for the resin inside the hose on existing rolling equipment, resulting in the inability to knead the resin before and during rolling.

[0004] Therefore, it is necessary to design a trenchless repair light-curing lining hose, production equipment, and production process that can knead the resin in the hose before and during rolling to turn large bubbles into small bubbles. Summary of the Invention

[0005] In response to the above-mentioned technical deficiencies, the purpose of the present invention is to provide a light-curing lining hose for trenchless repair of pipelines, as well as a production device and a production process, which can knead the resin in the hose before and during rolling to turn large bubbles into small bubbles.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: the present invention provides a production device for a light-curing lining hose for trenchless repair of pipelines, including a mobile vehicle, a lifting mechanism, a rotating mechanism, a large pressure roller and multiple small pressure rollers. The mobile vehicle can move horizontally and straightly relative to the ground. The lifting mechanism is fixedly installed in the middle of the mobile vehicle, and the rotating mechanism is fixedly installed on the lifting frame of the lifting mechanism. The rotating mechanism includes a rotating frame that can rotate and swing. The large pressure roller and multiple small pressure rollers are all rotatably installed on the rotating frame. The bottom of the large pressure roller and the bottom of the multiple small pressure rollers are arranged at the same height compared to the vertical direction.

[0007] Preferably, it also includes multiple friction rollers, which are staggered with multiple small pressure rollers. A stretching mechanism and a swinging mechanism are fixedly arranged on the rotating frame. The stretching mechanism includes a lifting seat and a slide slidably connected to the lifting seat. The multiple friction rollers are rotatably installed on the slide, and the swing rod of the swing mechanism is fixedly connected to the slide.

[0008] Preferably, the swing mechanism also includes a rotating rod, an articulated rod and a rotating motor. The rotating motor is fixedly mounted on the rotating frame through a motor seat. The rotating rod is fixedly mounted on the output end of the rotating motor. One end of the articulated rod is hinged to the rotating rod, and the other end of the articulated rod is hinged to the swing rod. A plurality of sliding columns are fixedly arranged on the lifting seat, and a plurality of slides are fixedly arranged on the slide frame and are slidably connected to the sliding columns.

[0009] Preferably, a clamping shaft is fixedly provided on the top of the slide, a clamping seat is fixedly provided on the rotating frame, a clamping slot is provided on the clamping seat for the slide column to be horizontally clamped in, and an arc plate is provided at the bottom of the slot, which fits with the clamping shaft when pulled upward.

[0010] Preferably, it also includes multiple support shafts that are slidably connected to the friction roller, and each support shaft is provided with a rotatable slide at both ends, the slide is slidably connected to the rotating frame, a spline hole is opened in the middle of the friction roller, and the middle cross-section of the support shaft is the same as the spline hole profile of the friction roller.

[0011] Preferably, the stretching mechanism also includes two guide columns and an electric push rod 2, the bottoms of the two guide columns are fixedly connected to the lifting seat, the electric push rod 2 is fixedly installed on the rotating frame, the output end of the electric push rod 2 is fixedly connected to the top of the lifting seat, the guide columns are slidably connected to the rotating frame, and the bottoms of the guide columns are fixedly connected to the top of the lifting seat.

[0012] Preferably, the rotating mechanism also includes multiple electric push rods, one end of the electric push rod is hinged to the lifting frame, the middle of the rotating frame is located directly below the lifting frame, the other end of the electric push rod is hinged to the right top of the rotating frame, and a rotating rod is fixedly provided on the left top of the rotating frame, and the rotating rod is hinged to the lifting frame.

[0013] The production process of a light-curing lining hose production device for trenchless pipeline repair includes the following steps:

[0014] Step 1: The stretching mechanism pushes the bottom of the friction roller downward to pass through the bottom of the small pressure roller and squeeze with the top of the hose. The small pressure roller is then driven horizontally by the mobile vehicle, and the swing mechanism pushes the friction roller to move back and forth.

[0015] Step 2: When the thickness of the hose needs to be quickly compressed, the working section of the rotating mechanism rotates in the opposite direction of S1, so that the bottom of the large pressing roller is lower than the bottoms of the multiple small pressing rollers. Only the large pressing roller is in contact with the hose. The large pressing roller is then moved by the mobile vehicle to roll the hose multiple times.

[0016] Step 3: When the hose needs to be extruded in multiple layers at the same time, the working section of the rotating mechanism rotates and switches along the S1 direction, so that the multiple small pressing rollers are in a stepped shape. The multiple small pressing rollers are in contact with the hose, and then the small pressing rollers are moved by the mobile vehicle to roll the hose;

[0017] Step 4: In step 3, when the small pressure roller is rolling, the stretching mechanism pushes the friction roller downward to contact the bulging hose when the small pressure roller is rolling, and at the same time, the swing mechanism pushes the friction roller to reciprocate;

[0018] Step 5: When the top flatness of the hose needs to be adjusted, the working section of the rotating mechanism rotates to a horizontal state, and the large pressing roller and multiple small pressing rollers squeeze the top of the hose at the same time.

[0019] The hose produced by the pipeline trenchless repair light-curing lining hose production device includes an outer film layer, a composite layer, an inner film layer and a transparent protective film which are sequentially laminated inwards. The composite layer is made of a mixture of glass fiber composite felt and light-curing resin.

[0020] Preferably, the outer film layer includes an anti-ultraviolet outer film and a non-woven waterproof membrane for isolating the anti-ultraviolet outer film from the composite layer.

[0021] The beneficial effects of the present invention are as follows: the light-curing lining hose for trenchless pipe repair, as well as its production device and production process, can knead the hose by using a stretching mechanism to push the bottom of the friction roller through the bottom of the small pressure roller before rolling. The friction roller is then driven to swing back and forth by a swinging mechanism, and is moved by a mobile vehicle. During the rolling process, the hose is rolled by multiple small pressure rollers at an angle, which produces bulges. The friction roller descends to contact and knead the bulges, so that the resin in the hose is kneaded during the rolling process, further ensuring that large bubbles are reduced to small bubbles.

[0022] Regardless of the height of the friction roller adjusted by the stretching mechanism, the swing mechanism mounted on the rotating frame can push the friction roller to swing back and forth. At the same time, when the stretching mechanism moves upward to its highest position, the swing mechanism pulls, causing the clamping shaft to engage with the clamping seat, providing support for the friction roller.

[0023] The rolling mechanism can adjust the pressure roller to press the hose individually, with multiple smaller rollers, or with both a large roller and multiple smaller rollers simultaneously. This allows the roller position to be adjusted to accommodate varying hose thicknesses, ensuring the hose is precisely flattened. Furthermore, the angled rolling of the smaller rollers can be combined with the kneading motion of the friction roller, resulting in multiple simultaneous kneading cycles and a higher kneading frequency.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Embodiment: The present invention provides a light-curing lining hose for trenchless repair of pipelines, and a production device and a production process, such as Figure 1-13 As shown, the apparatus comprises a mobile vehicle 1, a lifting mechanism 2, a rotating mechanism 3, a large pressure roller 4, and a plurality of small pressure rollers 5. The mobile vehicle 1 can move horizontally and linearly relative to the ground. The lifting mechanism 2 is fixedly mounted in the middle of the mobile vehicle 1. The rotating mechanism 3 is fixedly mounted on the lifting frame 2a of the lifting mechanism 2. The rotating mechanism 3 includes a rotating frame 3a that can rotate and swing. The large pressure roller 4 and the plurality of small pressure rollers 5 are both rotatably mounted on the rotating frame 3a. The bottom of the large pressure roller 4 and the bottom of the plurality of small pressure rollers 5 are arranged at the same height relative to the vertical direction. When squeezing the hose 10, three states can be switched to better adjust the thickness and flatten the hose 10.

[0041] Among them, the first will be along Figure 4 The S1 is rotated in the opposite direction so that the bottom of the large pressing roller 4 is lower than the bottoms of the multiple small pressing rollers 5. At this time, during rolling, only the large pressing roller 4 squeezes the hose 10. Through this squeezing method, the speed can be increased when the mobile vehicle 1 moves, and the hose 10 can be squeezed thinner faster.

[0042] When it is necessary to extrude multiple layers of thickness to the hose 10 at the same time, Figure 4The plurality of small pressing rollers 5 are rotated in the S1 direction to form a stepped shape. In this way, multiple layers of thickness of the hose 10 can be squeezed during one movement of the mobile vehicle 1. This squeezing method is suitable for squeezing out light-curing resin in small amounts multiple times at the end of the process to make the resin inside the hose 10 more uniform.

[0043] At the end, the bottoms of the large pressing roller 4 and the plurality of small pressing rollers 5 are made at the same height, as shown in FIG. Figure 2 As shown, at this time, the hose 10 can be squeezed multiple times at equal heights by moving the mobile vehicle 1 horizontally, so that the excess trace resin in the hose 10 can be completely squeezed out at this time. By the above three methods working in sequence, the hose 10 will be completely flattened.

[0044] Among them Figure 2 As shown, the lifting mechanism 2 can use an electric slide to pull the lifting frame 2a, but is not limited to this structure. The mobile vehicle 1 is connected to the ground using a slide and rails. A rack is provided on the ground, and a rotatable gear is provided inside the mobile vehicle 1 to mesh and move, ensuring that the mobile vehicle 1 can achieve horizontal movement.

[0045] It also includes multiple friction rollers 6, which are staggered with multiple small pressure rollers 5. A stretching mechanism 7 and a swing mechanism 8 are fixedly installed on the rotating frame 3a. The stretching mechanism 7 includes a lifting seat 7a and a slide 7b slidably connected to the lifting seat 7a. Multiple friction rollers 6 are rotatably mounted on the slide 7b. The swing rod 8a of the swing mechanism 8 is fixedly connected to the slide 7b. Figure 4 As shown, at the beginning, the bottom height of the friction roller 6 will be higher than the bottom height of the small pressure roller 5. When large bubbles need to be removed, the stretching mechanism 7 can be used to push the friction roller 6 downwards so that the friction roller 6 moves along the pressure roller 5. Figure 4 The direction indicated by the arrow is downward movement. The movement of the friction roller 6 is divided into two situations:

[0046] First, the bottom of the friction roller 6 is lowered through the bottom of the small pressure roller 5, and the height of the lowering is as follows: Figure 7 As shown, during horizontal movement, only the friction roller 6 contacts the hose 10 , that is, the stretching mechanism 7 pushes the friction roller 6 to perform reciprocating motion to rub the hose 10 , so that large bubbles in the hose 10 are squeezed out.

[0047] Secondly, the friction roller 6 does not pass through the small pressure roller 5 when it is lowered. Figure 8 As shown, superimpose along Figure 4 In the state shown, when moving horizontally, the small pressure roller 5 squeezes the resin to form a bulge, and then the friction roller 6 squeezes the bulge back and forth, so that the bubbles in the bulge are squeezed and turned into small bubbles. During the continued pushing process of the small pressure roller 5, the small bubbles can be better brought out.

[0048] The swing mechanism 8 also includes a rotating rod 8b, an articulated rod 8c, and a rotating motor 8d. The rotating motor 8d is fixedly mounted on the rotating frame 3a via a motor mount. The rotating rod 8b is fixedly mounted on the output end of the rotating motor 8d. One end of the articulated rod 8c is hinged to the rotating rod 8b, and the other end of the articulated rod 8c is hinged to the swing rod 8a. A plurality of slide posts 7c are fixedly mounted on the lifting base 7a, and a plurality of slide plates 7d are fixedly mounted on the slide 7c, which are slidably connected to the slide posts 7c. When the slide 7b is adjusted downward, the rotating rod 8b maintains a constant angle, while the slide plates 7d slide horizontally along the slide posts 7c, allowing the slide 7b to descend. After adjustment is complete, the slide posts 7c are fixed, and the rotating motor 8d drives the rotating rod 8b to rotate. This drives the articulated rod 8c, via the swing rod 8a, to pull the slide 7b back and forth, causing the friction roller 6 to knead the hose 10. By adopting the above-mentioned structural arrangement, no matter to which height the slide 7b is adjusted, the swing mechanism 8 can push the swing rod 8a to swing back and forth at any height without considering the position of the swing rod 8a.

[0049] When the device is not in use, the full weight of the friction roller 6 is constantly pressed against the stretching mechanism 7, which can easily damage it. To address this, a clamping shaft 7e is fixed to the top of the carriage 7b, and a clamping seat 7f is fixed to the rotating frame 3a. The clamping seat 7f defines a slot 7f1 for the horizontal engagement of the slide post 7c. A curved plate 7f2 is located at the bottom of the slot 7f1, which engages the clamping shaft 7e when it is pulled upward. Due to the restraining action of the hinged rod 8c, the clamping shaft 7e slides horizontally along the slide post 7c when the carriage 7b is pulled. The combined effects of these two movements result in an arc-shaped motion of the clamping shaft 7e. In the final stage of its motion, the clamping shaft 7e moves in alignment with the curved plate 7f2, guiding and limiting its position, ensuring that it is precisely engaged with the slot 7f1. After the lifting seat 7a is pulled up, the rotating rod 8b is rotated counterclockwise to pull the slide 7b to slide along the axial direction of the slide column 7c, so that the card shaft 7e is locked into the card groove 7f1 to support the slide 7b and prevent the weight of the friction roller 6 from acting on the stretching mechanism 7 for a long time.

[0050] To enhance the stability of the reciprocating motion of the friction roller 6, multiple support shafts 9 are slidably connected to the friction roller 6. Each support shaft 9 is provided with a rotatable slide 9a at each end. The slide 9a is slidably connected to the rotating frame 3a, which has a slot for the slide 9a to slide vertically. This ensures that the support shaft 9 can move vertically when the stretching mechanism 7 is pulling. The slides 9a also limit the left and right sides of the support shaft 9, improving the support stability of the support shaft 9 and ensuring greater stability when the friction roller 6 slides on the support shaft 9. A spline hole is provided in the center of the friction roller 6, and the cross-section of the support shaft 9 has the same profile as the spline hole of the friction roller 6. Displacement seats 6a are provided at each end of the friction roller 6. The friction roller 6 is rotatably connected to the displacement seats 6a. The displacement seats 6a are fixed to the bottom of the slide 7b. When the slide 7b moves, the displacement seats 6a drive the friction roller 6 to move, causing the friction roller 6 to oscillate back and forth on the support shaft 9. The friction roller 6 is provided with a plurality of balls evenly distributed along the axis direction, and the hose 10 is squeezed by the reciprocating motion of the plurality of balls.

[0051] The stretching mechanism 7 also includes two guide posts 7h and a second electric push rod 7j. The bottoms of the two guide posts 7h are fixedly connected to the lifting seat 7a. The second electric push rod 7j is fixedly mounted on the rotating frame 3a. The output end of the second electric push rod 7j is fixedly connected to the top of the lifting seat 7a. The guide posts 7h are slidably connected to the rotating frame 3a, and the bottoms of the guide posts 7h are fixedly connected to the top of the lifting seat 7a. By controlling the operation of the second electric push rod 7j, the lifting seat 7a is pulled vertically upward, and the movement of the lifting seat 7a is guided by the guide posts 7h.

[0052] The rotating mechanism 3 also includes a plurality of electric push rods 3c. One end of the electric push rod 3c is hingedly connected to the lifting frame 2a. The middle of the rotating frame 3a is located directly below the lifting frame 2a. The other end of the electric push rod 3c is hingedly connected to the top right side of the rotating frame 3a. A rotating rod 3b is fixedly mounted on the top left side of the rotating frame 3a and hingedly connected to the lifting frame 2a. By controlling the working end of the electric push rod 3c to extend, the rotating frame 3a rotates to the left along the hinged connection between the rotating rod 3b and the lifting frame 2a. Conversely, retracting the working end of the electric push rod 3c rotates the rotating frame 3a to the right.

[0053] The production process of a light-curing lining hose production device for trenchless pipeline repair includes the following steps:

[0054] Step 1: The stretching mechanism 7 pushes the bottom of the friction roller 6 downward to pass through the bottom of the small pressure roller 5 and squeeze with the top of the hose 10, as shown in FIG. Figure 7As shown, the small pressure roller 5 is driven horizontally by the mobile vehicle 1, and the swing mechanism 8 pushes the friction roller 6 to move back and forth, so that the friction roller 6 squeezes the light-curing resin in the hose 10, so that the large bubbles in the hose 10 are broken, making it easier for subsequent bubbles to be removed together with the extruded resin.

[0055] Step 2: When the thickness of the hose 10 needs to be quickly compressed, the working section of the rotating mechanism 3 rotates and switches in the opposite direction of S1, so that the bottom of the large pressing roller 4 is lower than the bottom of the multiple small pressing rollers 5, and only the large pressing roller 4 is in contact with the hose 10. The large pressing roller 4 is then moved by the mobile vehicle 1 to roll the hose 10 multiple times; multiple rolling operations squeeze out more light-curing resin from the hose 10.

[0056] Step 3: When it is necessary to extrude multiple layers of thickness on the hose 10 at the same time, the working section of the rotating mechanism 3 rotates and switches along the S1 direction, so that the multiple small pressing rollers 5 are stepped, and the multiple small pressing rollers 5 are in contact with the hose 10, and then the small pressing rollers 5 are moved by the mobile vehicle 1 to roll the hose 10; so that the multiple small pressing rollers 5 extrude the hose 10 at the same time, and the hose 10 is rolled synchronously in layers.

[0057] Step 4: In the step 3, when the small pressure roller 5 is rolling, the stretching mechanism 7 pushes the friction roller 6 downward to contact the hose 10 that bulges when the small pressure roller 5 is rolling, and at the same time the swing mechanism 8 pushes the friction roller 6 to reciprocate; in this way, when the small pressure roller 5 is rolling, large bubbles will remain in the lower layer of resin, and the friction roller 6 can roll again to rub and break the large bubbles that are squeezed upward.

[0058] Step 5: When the top flatness of the hose 10 needs to be adjusted, the working section of the rotating mechanism 3 rotates to a horizontal state, and the large pressing roller 4 and multiple small pressing rollers 5 squeeze the top of the hose 10 at the same time, so that it can be flattened for the last time. At the same time, rolling can ensure that the thickness of the hose 10 is flat.

[0059] The hose produced by the device for producing trenchless repair light-curing lined hoses includes an outer film layer 11, a composite layer 12, an inner film layer 14 and a transparent protective film 13 which are sequentially bonded inwards. The composite layer 12 is made of a glass fiber composite felt mixed with a light-curing resin. The glass fiber composite felt allows it to be better absorbed and fused with the light-curing resin, and the resin can flow better in it during multiple rolling. The outer film layer 11 includes an anti-UV outer film and a non-woven waterproof film for isolating the anti-UV outer film from the composite layer 12. The anti-UV outer film prevents the light-curing resin inside from being directly exposed to sunlight and solidified during transportation and storage. The inner film layer 14 is a highly light-transmitting structure, and its material can be polyetheretherketone or polymethyl methacrylate.

[0060] During use, the trenchless pipe repair light-curing lining hose, production device, and production process can push the bottom of the friction roller 6 through the bottom of the small pressure roller 5 through the stretching mechanism 7 before rolling. The friction roller 6 is then pushed back and forth by the swing mechanism 8, and is driven to move by the mobile vehicle 1 to knead the hose. During the rolling process, the hose 10 is rolled by multiple small pressure rollers 5 at an angle, which will produce bulges. The friction roller 6 descends to contact and knead the bulges, so that the resin in the hose is kneaded during the rolling process, further ensuring that large bubbles are reduced to small bubbles.

[0061] Regardless of the height of the friction roller 6 adjusted by the stretching mechanism 7, the swing mechanism 8 mounted on the rotating frame 3a can push the friction roller 6 to swing back and forth. At the same time, when the stretching mechanism 7 moves upward to its highest position, the swing mechanism 8 pulls, causing the clamping shaft 7e to engage with the clamping seat 7f, providing support for the friction roller 6.

[0062] The rolling device can adjust the large roller 4 to roll the hose 10 individually, the multiple small rollers 5 to roll the hose 10, or the large roller 4 and multiple small rollers 5 to roll the hose 10 simultaneously. This allows the position of the rollers to be adjusted according to the thickness of the hose 10, ensuring that the hose 10 is precisely rolled and flattened. Furthermore, the tilted rolling of the multiple small rollers 5 on the hose 10 can be combined with the kneading motion of the friction roller 6, resulting in multiple simultaneous kneading operations and a higher kneading frequency.

[0063] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and equivalents of the present invention, the present invention is intended to include such changes and modifications.
