Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, specifically to a trenchless pipeline repair UV device. Background Technology

[0002] In urban construction and maintenance, pipelines serve as crucial infrastructure, undertaking the critical task of transporting various media such as water, gas, and oil. However, with the passage of time and the erosion of the external environment, pipelines experience aging and damage, severely impacting their normal functionality. Traditional pipeline repair methods often require large-scale excavation operations, which not only disrupts surface traffic and affects the lives of nearby residents but also causes significant economic losses and environmental damage.

[0003] Trenchless pipeline repair technology has emerged, enabling pipeline repair with minimal or no damage to the ground, offering advantages such as short construction periods and minimal environmental impact. UV curing repair technology is a commonly used method in trenchless pipeline repair, utilizing ultraviolet curing lamps to cure the lining material, thereby achieving pipeline repair.

[0004] However, existing trenchless pipeline repair UV equipment has poor adaptability when dealing with pipes of different inner diameters. Because pipe inner diameters vary, and traditional UV equipment typically has a fixed structure, it's difficult to flexibly adjust to different pipe inner diameters. This necessitates replacing equipment of different specifications when repairing pipes of different inner diameters, increasing construction costs and operational difficulty, and affecting repair efficiency and quality. With technological advancements, technologies have emerged that can adjust the length of the roller outriggers; however, the adjustment process requires individual adjustment of each roller outrigger's length, and achieving equal length adjustment for all roller outriggers is difficult. Therefore, developing a trenchless pipeline repair UV device capable of adapting to repairing pipes of different inner diameters is of significant practical importance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a trenchless pipeline repair UV device, solving the problem of poor adaptability of some trenchless pipeline repair UV devices when dealing with pipelines of different inner diameters.

This necessitates replacing different specifications of equipment when repairing pipelines of different inner diameters, increasing construction costs and operational difficulty, and affecting repair efficiency and quality. Furthermore, the new technology requires individual adjustment of the length of each roller support leg during the roller support leg length adjustment process, making it difficult to achieve equal length adjustment of both roller support legs.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: The trenchless pipeline repair UV equipment includes a support unit and a curing lamp tube, wherein the curing lamp tube is installed on the support unit, and a diameter-changing unit is provided inside the support unit;

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] This utility model discloses a trenchless pipeline repair UV device.

[0036] Example 1: According to the appendix Figure 1-3 As shown, it includes a support unit 1 and a curing lamp 2. The curing lamp 2 is mounted on the support unit 1, and a variable diameter unit 3 is provided inside the support unit 1.

[0037] The variable diameter unit 3 includes:

[0038] Driver component 31;

[0039] Telescopic component 32, which is connected to drive component 31;

[0040] Roller 33 is connected to telescopic assembly 32. Drive assembly 31 is used to drive telescopic assembly 32 to extend and retract to adjust the outer diameter of roller 33 to adapt to pipe repair with different inner diameters.

[0041] Furthermore, the support unit 1 includes:

[0042] The support base 11 is provided in two sets and is arranged symmetrically.

[0043] Connecting rod 12 is fixedly connected between two bearing seats 11.

[0044] Furthermore, multiple curing lamps 2 are configured, and these multiple curing lamps 2 are circumferentially equidistantly installed between two support seats 11. As the equipment travels along the pipeline, the multiple curing lamps 2 operate simultaneously, emitting ultraviolet light to cure the lining material inside the pipeline, thereby achieving pipeline repair.

[0045] Example 2: According to the appendix Figure 1-3 As shown, it includes a support unit 1 and a curing lamp 2. The curing lamp 2 is mounted on the support unit 1, and a variable diameter unit 3 is provided inside the support unit 1.

[0046] The variable diameter unit 3 includes:

[0047] Driver component 31;

[0048] Telescopic component 32, which is connected to drive component 31;

[0049] Roller 33 is connected to telescopic assembly 32. Drive assembly 31 is used to drive telescopic assembly 32 to extend and retract to adjust the outer diameter of roller 33 to adapt to pipe repair with different inner diameters.

[0050] Furthermore, the drive component 31 includes:

[0051] Rotating component 311;

[0052] Rotating rod 312, one end of which is fixedly connected to rotating component 311;

[0053] Worm 313 is fixedly sleeved on rotating rod 312;

[0054] The worm gear 314 meshes with the worm 313. Rotating the rotating component 311 causes the rotating rod 312 to rotate, and the worm 313 on the rotating rod 312 rotates accordingly. Because the worm 313 is meshed with the worm gear 314, the worm gear 314 rotates along with the worm 313. The meshing connection between the worm 313 and the worm gear 314 has a self-locking function, ensuring stable operation of the equipment within the pipeline after adjusting the outer diameter of the roller 33, preventing changes in the position of the roller 33 due to unexpected circumstances, and avoiding disruption to the normal progress of repair work.

[0055] Furthermore, the telescopic component 32 includes:

[0056] The rotating shaft 321 is fixedly inserted into the worm gear 314;

[0057] Turntable 322 is fixedly connected to rotating shaft 321;

[0058] Slider 323, multiple sliders 323 are provided, and multiple sliders 323 are slidably connected in the turntable 322;

[0059] Telescopic support leg 324, one end of which is fixedly connected to slider 323.

[0060] Furthermore, the turntable 322 has multiple arc-shaped grooves equidistantly spaced on its circumference, and these arc-shaped grooves are slidably connected to the slider 323. The slidable connection between the multiple arc-shaped grooves equidistantly spaced on the turntable 322 and the slider 323 allows the telescopic support leg 324 to extend and retract synchronously with the rotation of the turntable 322. This results in a flexible and smooth adjustment process, enabling it to quickly and accurately adapt to the requirements of different pipe inner diameters.

[0061] Furthermore, roller 33 is rotatably connected to the other end of telescopic support leg 324. Rotary shaft 321 is fixedly inserted into worm gear 314, and is fixedly connected to turntable 322. Therefore, the rotation of worm gear 314 will drive turntable 322 to rotate as well. When turntable 322 rotates, slider 323 slides within the arc-shaped groove, thereby driving telescopic support leg 324 to extend and retract, thus adjusting the outer diameter of roller 33, allowing roller 33 to fit tightly against the inner wall of the pipe, providing stable support for the equipment's movement within the pipe.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
