Description

Technical Field

[0001] This utility model relates to the field of curing equipment, specifically a curing equipment for inner-lined flexible tubes. Background Technology

[0002] The inner-lined flexible hose consists of an outer membrane, an outer felt, a glass fiber impregnated layer, an inner membrane, and a replacement thread. It is manufactured by folding different materials in a staggered manner, followed by vacuum resin infusion and rolling processes. The inner-lined flexible hose is then pulled into the existing pipe to be repaired, inflated to expand, and tightly adheres to the original pipe. The original pipe serves as the outer membrane, and the inner membrane of the hose serves as the inner membrane. Under ultraviolet light, the resin is cured to form a composite inner-lined pipe with a certain strength. This pipe repair technology significantly extends the service life of the pipeline and reduces costs for users. When laying the inner-lined flexible hose, a hose curing machine is often used to cure the inside of the hose. The hose curing machine is a mechanical device that emits usable strong ultraviolet light to cure the hose.

[0003] According to Chinese Patent Publication No. CN219902988U, a liner hose curing device is disclosed. This utility model can fix a first fixing rod and a second fixing rod. After the roller is installed, the extension and retraction lengths of the first fixing rod and the second fixing rod can be adjusted to correspond to the hose to be cured. This achieves the effect of easy adjustment of the hose curing machine.

[0004] Regarding the aforementioned patent content, an ultraviolet lamp is used to cure the inner lining tube. However, when the ultraviolet lamp is idle, it is directly exposed to the air, which makes it easy for external dust, oil, and other stains to adhere to the surface of the lamp. Since the lamp is the "energy core" for curing, the surface cleanliness directly affects the ultraviolet light output intensity. After dust adheres to the lamp surface, the ultraviolet light transmittance decreases, resulting in insufficient curing of the resin inside the tube and insufficient strength of the composite inner lining tube. This reduces the effectiveness of the ultraviolet lamp and the curing efficiency of the inner lining tube. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a curing device for inner lining tubes to solve the technical problem that when ultraviolet lamps are idle, they are directly exposed to the air, which leads to dust or oil stains easily adhering to the surface of the lamp tube.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a curing device for inner-lined flexible tubes, comprising two mounting bases, an ultraviolet lamp tube installed between the two mounting bases, a first fixing ring installed on the outer wall of one mounting base, and a bolt threaded onto the first fixing ring; a second fixing ring installed on the outer wall of the other mounting base, wherein multiple grooves are formed on one side of the second fixing ring, and a washer is also fitted onto one side of the second fixing ring; multiple iron blocks are installed on one side of the washer; a permanent magnet is installed inside the grooves; a baffle is installed between the washer and the first fixing ring; and a screw hole is formed on the washer.

[0007] By adopting the above technical solution, when the equipment is idle, the ultraviolet lamp tube can be shielded and protected by the baffle to prevent dust and dirt from adhering to the ultraviolet lamp tube, thereby improving the protection effect of the ultraviolet lamp tube.

[0008] Furthermore, the outer walls of both mounting bases are fitted with threaded sleeves and movable rings, and the outer walls of the mounting bases are also fitted with four guide rods, with slides fitted on the outer walls of the guide rods.

[0009] By adopting the above technical solution, the guide rod can guide the slide block, thereby improving the stability of the slide block during movement.

[0010] Furthermore, a pull plate is rotatably connected between the slide and the movable ring via a rotating shaft, and a connecting rod is installed on the side of the slide away from the mounting base, with a roller installed at the end of the connecting rod.

[0011] By adopting the above technical solution, the sliding block can move the connecting rod when it moves, and then move the roller to adjust the position of the roller.

[0012] Furthermore, an annular groove is provided on one side of the movable ring, and a slip ring is provided inside the annular groove. One side of the slip ring is fixedly connected to the threaded sleeve.

[0013] By adopting the above technical solution, when the threaded sleeve rotates, it will drive the slip ring to slide inside the movable ring, and the movement of the threaded sleeve can simultaneously drive the movement of the movable ring.

[0014] Furthermore, the outer wall of the guide rod is provided with an anti-slip sleeve made of silicone rubber material, and the inner wall of the slide block is in contact with the anti-slip sleeve.

[0015] By adopting the above technical solution, the anti-slip sleeve can enhance the friction between the slide and the guide rod, prevent the slide from shifting during equipment operation, and improve stability.

[0016] Furthermore, the outer wall of the mounting base is provided with threads on one side, the threaded sleeve is threadedly connected to the mounting base, and the outer wall of the threaded sleeve is provided with anti-slip texture.

[0017] By adopting the above technical solution, the anti-slip texture makes it easier for workers to rotate the threaded sleeve, allowing the threaded sleeve to move.

[0018] Furthermore, a sealing ring made of silicone rubber is installed on one side of the gasket ring, and the sealing ring is in contact with one side of the second fixing ring.

[0019] By adopting the above technical solution, the sealing ring can improve the sealing performance between the gasket ring and the second fixing ring, preventing external dust from entering the interior of the baffle.

[0020] Furthermore, the iron block is located inside the groove, and one side of the iron block is attached to the permanent magnet.

[0021] By adopting the above technical solution, the stability of the gasket can be improved after the iron block and the permanent magnet are adsorbed and bonded together, so that the baffle can block the ultraviolet lamp tube.

[0022] Furthermore, the ultraviolet lamp is located inside the baffle, which is made of PVC-coated nylon fabric.

[0023] By adopting the above technical solution, the baffle made of PVC coated nylon cloth can be folded or unfolded, improving its applicability.

[0024] Furthermore, multiple guard rods are installed between the two mounting bases.

[0025] By adopting the above technical solution, the guard rod enhances the connection strength between the two mounting bases, prevents the equipment from deforming under stress, and protects the lamp tube.

[0026] In summary, the present invention has the following main advantages: 1. This utility model is provided with a first fixing ring, a second fixing ring, a baffle, a washer, a screw hole, a groove, a permanent magnet, an iron block, and a bolt. When the equipment is idle, the operator can unscrew the bolt from the screw hole to release the washer's restriction. Then, the washer can be pulled to unfold the baffle. When the iron block on one side of the washer is inserted into the groove, the permanent magnet will attract the magnet to position the washer. In this way, the baffle can block the ultraviolet lamp tube, thereby protecting the ultraviolet lamp tube in the idle state and preventing dust or stains from adhering to the ultraviolet lamp tube. 2. This utility model features a sealing ring, which improves the sealing between the gasket ring and the second fixing ring, preventing external dust from entering the interior of the baffle cylinder. Furthermore, the baffle cylinder is made of PVC-coated nylon cloth, making it easy to fold or unfold, thus improving its applicability. 3. This utility model, by comprising a threaded sleeve, a movable ring, a slip ring, an annular groove, a pull plate, a guide rod, a slide block, a connecting rod, and an anti-slip sleeve, allows the operator to manually rotate the threaded sleeve according to the inner diameter of the hose to be cured. The threaded sleeve engages with the threaded mounting base, causing the slip ring to rotate within the annular groove of the movable ring, simultaneously pushing the movable ring axially. The movable ring, via the pull plate, pulls the slide block to slide on the guide rod. The slide block drives the connecting rod and rollers to extend or retract until the rollers are in contact with the inner wall of the hose. This method allows adjustment of the four roller positions without sequentially adjusting them, simplifying the adjustment process and improving the efficiency of roller position adjustment. Furthermore, the anti-slip sleeve enhances the friction between the slide block and the guide rod, preventing the slide block from shifting during operation and improving stability.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure. Example 1

[0031] A curing device for inner-lined flexible tubes, such as Figures 1-9 As shown, the device includes two mounting bases 1, with an ultraviolet lamp 2 installed between them. A first fixing ring 14 is mounted on the outer wall of one mounting base 1, and a bolt 23 is threaded onto the first fixing ring 14. A second fixing ring 15 is mounted on the outer wall of the other mounting base 1, with multiple grooves 20 on one side of the second fixing ring 15. A washer 17 is also fitted onto one side of the second fixing ring 15, with multiple iron blocks 22 mounted on one side of the washer 17. A permanent magnet 21 is installed inside the grooves 20. A baffle 16 is installed between the washer 17 and the first fixing ring 14. A screw hole 19 is provided on the washer 17. When the equipment is idle, the UV lamp tube 2 can be shielded and protected by the baffle 16 to prevent dust and dirt from adhering to the UV lamp tube 2, thereby improving the protection effect of the UV lamp tube 2. The iron block 22 is located inside the groove 20, and one side of the iron block 22 is attached to the permanent magnet 21. When the iron block 22 and the permanent magnet 21 are attracted and attached, the stability of the gasket 17 can be improved, so that the baffle 16 can shield the UV lamp tube 2. The UV lamp tube 2 is located inside the baffle 16. The baffle 16 is made of PVC coated nylon cloth material. The baffle 16 with PVC coated nylon cloth can be folded or unfolded to improve its applicability.

[0032] See Figures 1-7 Both mounting bases 1 have threaded sleeves 5 and movable rings 6 fitted on their outer walls. Four guide rods 10 are also mounted on the outer walls of the mounting bases 1, and slide blocks 11 are fitted on the outer walls of the guide rods 10. The slide blocks 11 are slidably connected to the guide rods 10, and the guide rods 10 guide the slide blocks 11, thereby improving the stability of the slide blocks 11 during movement. A pull plate 9 is rotatably connected to the slide blocks 11 and the movable rings 6 via a rotating shaft. A connecting rod 12 is mounted on the side of the slide block 11 away from the mounting base 1, and a roller 4 is mounted on the end of the connecting rod 12. When the slide block 11 moves, it can drive the connecting rod 12 to move. Then, the roller 4 is moved to adjust its position. An annular groove 7 is provided on one side of the movable ring 6, and a sliding ring 8 is provided inside the annular groove 7. One side of the sliding ring 8 is fixedly connected to the threaded sleeve 5. When the threaded sleeve 5 rotates, it will drive the sliding ring 8 to slide inside the movable ring 6. The movement of the threaded sleeve 5 can simultaneously drive the movable ring 6 to move. One side of the outer wall of the mounting base 1 is provided with threads, and the threaded sleeve 5 is threadedly connected to the mounting base 1. The outer wall of the threaded sleeve 5 is provided with anti-slip texture. The anti-slip texture makes it convenient for the operator to rotate the threaded sleeve 5, so that the threaded sleeve 5 can move. Example 2

[0033] Based on the above embodiment 1, in order to improve the stability of the slide 11 and prevent it from sliding randomly, the following structure will be set.

[0034] Specifically, the outer wall of the guide rod 10 is provided with an anti-slip sleeve 13 made of silicone rubber material, and the inner wall of the slide block 11 is in contact with the anti-slip sleeve 13. The anti-slip sleeve 13 can enhance the friction between the slide block 11 and the guide rod 10, prevent the slide block 11 from shifting when the equipment is working, and improve stability. Example 3

[0035] Based on the above embodiment 1, in order to improve the sealing performance between the gasket 17 and the second fixing ring 15, the following structure will be provided.

[0036] Specifically, a sealing ring 18 made of silicone rubber is installed on one side of the gasket 17. The sealing ring 18 fits against one side of the second fixing ring 15. The sealing ring 18 can improve the sealing between the gasket 17 and the second fixing ring 15 and prevent external dust from entering the interior of the baffle 16. Example 4

[0037] Based on the above embodiment 1, the following structure will be set to improve the connection strength between the two mounting bases 1.

[0038] Specifically, multiple guard rods 3 are installed between the two mounting bases 1. The guard rods 3 enhance the connection strength between the two mounting bases 1, prevent the equipment from deforming under stress, and protect the lamp tube.

[0039] The working principle of this utility model is as follows: First, when the equipment is idle, the operator uses a tool to unscrew the bolt 23 on the first fixing ring 14. The bolt 23 exits from the screw hole 19 of the washer 17, releasing the axial restriction on the washer 17. Then, the baffle 16 is unfolded, and the washer 17 is pulled towards the second fixing ring 15. The washer 17 drives the PVC-coated nylon cloth baffle 16 connected to it. When unfolded (due to the flexibility and support of the PVC-coated nylon fabric, it can maintain its cylindrical shape without collapsing after unfolding), when the gasket 17 approaches the second fixing ring 15, the iron block 22 on one side of the gasket 17 is precisely inserted into the groove 20 of the second fixing ring. The permanent magnet 21 in the groove is instantly attracted to the iron block 22, achieving rapid positioning of the gasket 17. Meanwhile, the silicone rubber sealing ring 18 on the gasket 17 fits tightly against the side of the second fixing ring 15, sealing the gap between them and preventing external dust from entering the baffle 16 through the gap. The baffle 16 completely encloses the ultraviolet lamp tube 2, forming a fully enclosed dustproof space. During idle periods, dust cannot come into contact with the ultraviolet lamp tube 2, achieving the protection goal. When this equipment is used to cure the inner lining hose, the operator can first adjust the roller 4 (to fit the inner diameter of the hose) before use. The operator manually rotates the threaded sleeve 5 on the outer wall of the mounting base 1. Since the outer wall of the mounting base 1 is threaded, the threaded sleeve 5 and the mounting base 1 are threaded together. When rotating, the threaded sleeve 5 moves along the axial direction of the mounting base 1. When the threaded sleeve 5 moves, the sliding ring 8 fixed on one side slides in the annular groove 7 of the movable ring 6, thereby pushing the movable ring 6 to move synchronously along the axial direction of the mounting base 1. When the movable ring 6 moves, it drives the pull plate 9 to rotate through the rotating shaft (the pull plate 9 can swing flexibly around the rotating shaft). The other end of the pull plate 9 pulls the slide 11 to slide along the guide rod 10 (the guide rod 10 guides the slide 11 to prevent deviation). When the slide 11 slides, it drives the roller 4 to extend or retract. When the position of the roller 4 is adjusted to the appropriate position, the operator no longer needs to rotate the threaded sleeve 5. The silicone rubber anti-slip sleeve 13 on the outer wall of the guide rod 10 is tightly fitted with the inner wall of the slide 11, increasing the friction between the two and improving the stability of the slide 11. Next, the staff manually separated the pad ring 17 from the second fixing ring 15 (overcoming the attraction force of the permanent magnet 21), pulled the pad ring 17 towards the first fixing ring 14, and at the same time folded the PVC coated nylon cloth baffle 16 (because the material is foldable, the thickness after folding is only 1-2cm, which can fit the outer wall of the first fixing ring 14 and does not occupy the working space of the lamp tube). Finally, the folded baffle 16 was temporarily fixed with bolts 23 to prevent it from loosening when moving. Then, the power is turned on and the ultraviolet lamp 2 is activated. The ultraviolet lamp 2 emits strong ultraviolet light, which irradiates the resin layer on the inner wall of the hose. The equipment rolls smoothly along the axial direction inside the hose through four rollers 4. The multiple guard rods 3 between the two mounting seats 1 enhance the overall rigidity and prevent the mounting seats 1 from being deformed by force (such as squeezing or bending) when the equipment moves, thereby protecting the internal ultraviolet lamp 2 from damage. During the movement of the equipment, the ultraviolet light continuously irradiates the resin inside the hose. The resin is cured under the action of ultraviolet light to form a composite inner lining tube until the equipment moves to the other end of the hose, completing the full-length curing.
