Description

Technical Field

[0001] This utility model relates to the field of pipeline repair equipment technology, and more specifically, it relates to a support mechanism for UV curing pipeline processing. Background Technology

[0002] UV-curing pipe repair technology revolutionizes pipe repair with its innovative trenchless method. This technology simply involves inserting a flexible composite hose into the old pipe and curing it with ultraviolet light, completing the repair in one step. It completely eliminates the cumbersome processes of traditional methods, such as scaffolding, pipe turning, and water usage, making the construction process simpler and faster, ultimately achieving multiple benefits including high efficiency, environmental friendliness, and cost savings.

[0003] In existing technologies, ultraviolet (UV) lamps are commonly used to locally cure damaged pipe sections. However, due to the complex internal environment of pipes and the lack of effective positioning and fixing measures, the UV lamps are prone to displacement or tilting during installation, resulting in inaccurate coverage of the repair area. This displacement leads to uneven distribution of UV energy received by the resin, causing insufficient curing in some areas and severely impacting the mechanical properties and long-term durability of the repair layer. Furthermore, in current pipe repair processes, the presence of foreign objects, dents, or incomplete pretreatment on the inner wall of the old pipe often prevents the inserted inner liner from achieving a complete and tight bond with the original outer liner. Gaps or air bubbles can easily remain between them, creating localized debonding areas. This poor bonding significantly weakens the integrity of the repair structure, potentially leading to secondary damage such as leakage and delamination during subsequent use, ultimately affecting the overall quality and service life of the repair.

[0004] In view of this, we propose a support mechanism for UV curing pipe processing. Utility Model Content

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a support mechanism for UV curing pipe processing, comprising three support rods, each end of which is fixedly connected to a fixing member 1, and two fixing members 2 are fixedly connected to the three support rods. Each fixing member 2 is hinged to circumferentially spaced swing rods, the ends of which are rotatably connected to electric wheels. Two sliders are slidably connected to the three support rods, each slider being hinged to circumferentially spaced hinge rods, which are hinged to adjacent swing rods. Each fixing member 2 is fixedly connected to a motor 1, the output shaft of which is fixedly connected to a threaded rod. The threaded rod passes through the slider and is rotatably connected to the fixing member 1, and is threadedly connected to the slider. The three support rods are provided with a support and clamping structure.

[0007] The present invention is further configured such that the three support rods are fixedly connected to two connecting plates, and an ultraviolet lamp and a transparent cover are fixedly connected between the two connecting plates, with the ultraviolet lamp located inside the transparent cover.

[0008] The present invention is further configured such that the supporting and pressing structure includes two rotating rings, which are rotatably connected to the two connecting plates respectively. Each rotating ring is hinged with an electric push rod that is spaced apart, and a roller pressing assembly is provided between the left and right adjacent electric push rods.

[0009] The present invention is further configured such that the roller pressing assembly includes two connecting sleeves, the two connecting sleeves are respectively hinged to two electric push rods, a connecting rod is slidably connected between the two connecting sleeves, and the connecting rod is rotatably connected to the pressure roller.

[0010] The present invention is further configured such that springs are sleeved on both the left and right sides of the connecting rod, and the two ends of the springs are respectively fixed to the end of the connecting rod and the adjacent connecting sleeve.

[0011] The present invention is further configured such that the rotating ring is fixedly connected to a toothed ring, the connecting plate is fixedly connected to a second motor, and the output shaft of the second motor is fixedly connected to a gear that meshes with the toothed ring.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a support mechanism for UV curing pipe processing, which has the following beneficial effects: 1. This utility model uses a motor to drive a threaded rod, controlling multiple sets of electric wheels to radially expand, thus stably supporting and centering the mechanism on the inner wall of the pipe. This structure avoids the problem of UV lamp strip displacement caused by unstable fixing in traditional operations, ensuring a constant distance between the UV lamp and the inner lining pipe wall, thereby guaranteeing the uniformity and sufficiency of UV irradiation and solving the hidden danger of insufficient curing caused by light source displacement.

[0015] 2. This utility model utilizes the coordinated control of an electric push rod and a second motor to enable the pressure roller to actively press and reciprocate against the inner lining tube wall. This function effectively eliminates residual air bubbles between the inner and outer lining tubes, forcing the inner lining tube to achieve a tight, all-around fit with the inner wall of the old pipe. This directly improves the problem of poor repair results caused by inadequate fit and enhances the overall quality of the repair layer. Attached Figure Description

Two sliders 6 are slidably connected to the three support rods 1. The sliders 6 are hinged to circumferentially spaced hinge rods 7, which are hinged to adjacent swing rods 4. A motor 1 8 is fixed to the fixing member 2. The output shaft of the motor 1 8 is fixedly connected to a threaded rod 9, which passes through the slider 6 and is rotatably connected to the fixing member 2. The threaded rod 9 is threadedly connected to the slider 6. The three support rods 1 are provided with a support and clamping structure. Two connecting plates 10 are fixedly connected to the three support rods 1. A UV lamp 11 and a transparent cover 12 are fixedly connected between the two connecting plates 10, with the UV lamp 11 located inside the transparent cover 12.

[0022] Please see Figures 3-6 The supporting and pressing structure includes two rotating rings 13, which are rotatably connected to two connecting plates 10. Each rotating ring 13 is hinged to spaced-apart electric push rods 14. A roller pressing assembly is positioned between adjacent electric push rods. The roller pressing assembly includes two connecting sleeves 15, which are hinged to the two electric push rods 14. A connecting rod 16 is slidably connected between the two connecting sleeves 15, and a pressure roller 17 is rotatably connected to the connecting rod 16. Springs 18 are fitted on both sides of the connecting rod 16, with the ends of the springs 18 connected to the ends of the connecting rod 16 and adjacent... Connecting sleeve 15 is fixedly connected; rotating ring 13 is fixedly connected to toothed ring 19; connecting plate 10 is fixedly connected to motor 20; the output shaft of motor 20 is fixedly connected to gear 21 that meshes with toothed ring 19; connecting plate 10 is fixedly connected to support shell 22; support shell 22 is fixedly connected to electric push rod 23; rotating ring 13 is slidably connected to sliding ring 24; sliding ring 24 is rotatably connected to connecting ring 25; connecting ring 25 is fixedly connected to spaced connecting pieces 26; connecting piece 26 has a through groove in the middle; electric push rod 14 is fixedly connected to fixing post 27; fixing post 27 is slidably connected to the through groove of adjacent connecting piece 26.

[0023] The working principle of this utility model: Place the device into the UV-curing inner liner tube, then start the two motors 8. The output shaft of the motor 8 drives the threaded rod 9 to rotate. The threaded rod 9 drives the slider 6 to slide along the three support rods 1 through the thread. The slider 6 drives the swing rod 4 to rotate along the fixed part 3 through the hinge rod 7 until the electric wheel 5 abuts against the inner wall of the UV-curing inner liner tube. Then start the electric wheel 5. The electric wheel 5 rotates inside the UV-curing inner liner tube, moving the device to the designated position.

[0024] During the above process, the UV-curable inner liner tube is brought into contact with the outer liner tube by the expanding gas. If the UV-curable inner liner tube is not fully in contact with the inner wall of the outer liner tube, the electric push rod 23 is activated. The telescopic end of the electric push rod 23 drives the sliding ring 24 to slide along the rotating ring 13. The sliding ring 24 drives the connecting ring 25 and the connecting piece 26 on it to move synchronously. The connecting piece 26 pulls the fixed column 27 outward, so that the electric push rod 14 swings along the rotating ring 13 until the electric push rod 14 swings to the vertical position. Then the electric push rod 23 is closed. During the swing of the electric push rod 14, the connecting sleeve 15 slides along the connecting rod 16, and the spring 18 is compressed. Then the electric push rod 14 is activated. The telescopic end of the electric push rod 14 drives the connecting rod 16 to move through the connecting sleeve 15, so that the pressure roller 17 abuts against the UV-curable inner liner tube.

[0025] Then, start motor 20. The output shaft of motor 20 drives gear ring 19 to rotate through gear 21. Gear ring 19 drives rotating ring 13 to reciprocate along connecting plate 10. Rotating ring 13 causes pressure roller 17 to reciprocate along UV-cured inner liner tube through electric push rod 14, thereby bonding the inner wall of UV-cured inner liner tube and outer liner tube, improving the bonding effect.

[0026] After completing the above operations, turn off motor 20 and control the telescopic ends of electric push rod 23 and electric push rod 14 to reset, so that connecting rod 16 and pressure roller 17 are reset. Then turn on ultraviolet lamp 11 to irradiate the UV-curable inner liner tube to cure it. After the UV-curable inner liner tube has cured, control the device to be removed from the pipeline.
