Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a UV curing repair inspection robot. Background Technology

[0002] As urban underground pipe networks age, underground facilities such as drainage pipes and cable tunnels often develop defects such as cracks, leaks, and corrosion. Traditional repair methods (such as excavation and replacement or manual lining repair) suffer from problems such as long construction cycles, high costs, and traffic disruptions. UV-CIPP (UV-cured in-situ pipe repair) is a trenchless pipe repair method primarily used for the rapid repair of underground drainage pipes, petrochemical pipelines, and cable tunnels. Its core principle involves using ultraviolet light to irradiate a flexible tube impregnated with photosensitive resin, causing it to rapidly cure and form a high-strength lining within the pipe.

[0003] Searching revealed that most existing curing and repair inspection robots have a cylindrical design with a ring of UV lamps installed on the outer wall. They move inside the pipe using electric wheels. For example, a UV curing device for pipe repair announced in patent publication number has this structural design. However, the applicant found that because pipe inner diameters vary, and the traditional robot structure has a fixed lamp position, the distance between the lamp and the pipe inner wall cannot be adjusted. When dealing with pipes with large inner diameters, the excessive distance between the lamp and the pipe inner wall will cause the UV light intensity to decrease, failing to achieve the ideal curing effect, prolonging the repair time, and reducing the repair efficiency.

[0004] Therefore, the applicant proposes a UV curing repair inspection robot to solve the problem. Utility Model Content

[0005] This invention provides a UV curing repair and inspection robot, which solves the problems mentioned in the background.

[0006] To solve the above-mentioned technical problems, this utility model provides a UV curing repair inspection robot, including a machine housing, with movable wheel assemblies installed on both sides of the machine housing, a UV lamp installed on the outer wall of the machine housing, and an adjustment assembly connected to the UV lamp and the machine housing. The adjustment assembly includes adjustment plates fixed on both sides of the UV lamp, the adjustment plates being inserted into the machine housing through an opening and sliding therein, and a cylindrical block installed on the side of the adjustment plate inside the machine housing, the cylindrical block sliding in a side sliding opening of a disc, the disc being installed at one end of the output shaft of a dual-axis motor.

[0007] A guide plate is inserted into the bottom of the adjusting plate. The guide plate is fixed to the outer wall of the cylinder, and the cylinder has two guide plates installed inside the machine housing.

[0008] A row of connecting plates is fixed at equal intervals on the outer wall of the cylinder, and the connecting plates are fixedly connected to the inner wall of the machine housing.

[0009] The dual-axis motor is located between two cylinders, and the output shaft passes through the inside of the cylinders. The flanges installed at both ends of the dual-axis motor are attached to the two cylinders and fixed with screws, while the discs are also attached to the other side of the cylinders.

[0010] A reinforcing plate is connected between two adjusting plates corresponding to one of the UV lamps, and a stabilizing spring connects the reinforcing plate to the cylinder.

[0011] The machine housing has a wire opening for the dual-axis motor wires to pass through. The side wall of the machine housing is fitted with a protective shell that surrounds the wire opening. A protective plate is installed on one side of the protective shell, and the protective plate has a circular wire hole.

[0012] A sealing ring made of corrosion-resistant rubber is bonded to the inner wall of the opening through which the adjustment plate passes through the machine housing.

[0013] Compared with related technologies, the UV curing repair and inspection robot provided by this utility model has the following beneficial effects:

[0014] 1. This utility model, through the design of the adjustment component, can flexibly adjust the distance between the UV lamp and the inner wall of the pipe according to the inner diameter of the pipe, ensuring that the ultraviolet light irradiates the photosensitive resin hose with the best intensity and uniformity, achieving efficient and high-quality repair, and greatly improving the repair effect and efficiency.

[0015] 2. After further optimization of the adjustment components through guide plates, reinforcing plates, and stabilizing springs, the adjustment plate can slide more stably, with higher overall strength and good stability during movement. The internal stability of the machine housing has also been optimized. The docking method between the dual-axis motor and the cylinder ensures that it does not shake during operation, and the close rotation of the disc and the cylinder also enhances its own stability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Depend on Figures 1-6 This utility model provides a UV curing repair inspection robot, including a machine housing 1, with movable wheel assemblies 11 installed on both sides of the machine housing 1, and a UV lamp 12 installed on the outer wall of the machine housing 1. The UV lamp 12 is connected to the machine housing 1 by an adjustment assembly 2, which includes adjustment plates 21 fixed on both sides of the UV lamp 12. The adjustment plates 21 are inserted into the machine housing 1 through an opening and slide inside. A cylindrical block 22 is installed on the side of the adjustment plate 21 inside the machine housing 1. The cylindrical block 22 slides in the sliding port 24 of the disc 23. The disc 23 is installed at one end of the output shaft 252 of the dual-axis motor 25.

[0025] By adjusting component 2, the machine housing 1 is placed horizontally on the inner wall of the pipe during operation. The moving wheel assembly 11 can move in contact with the inner wall of the pipe. This is a conventional design and can be adjusted according to the inner diameter of the pipe. The principle is not described in detail here. When it is necessary to adjust the distance between the UV lamp 12 and the inner wall of the pipe, simply start the dual-axis motor 25. Its output shaft 252 drives the disc 23 to rotate. As the disc 23 rotates, the sliding port 24 on its side will drive the cylindrical block 22 mounted on the adjusting plate 21 to move. Since the adjusting plate 21 is inserted into the machine housing 1 through the opening and can slide, Therefore, the movement of the cylindrical block 22 will cause the adjusting plate 21 to extend and retract within the machine housing 1. In this way, the UV lamp 12 fixed at the other end of the adjusting plate 21 will move accordingly, thereby realizing flexible adjustment of the distance between the UV lamp and the inner wall of the pipe. The user only needs to adjust the position of the UV lamp 12 by controlling the rotation angle and direction of the dual-axis motor 25 according to the size of the inner diameter of the pipe, ensuring that the ultraviolet light can irradiate the photosensitive resin tube inside the pipe with the best intensity and uniformity, so as to achieve efficient and high-quality repair effect. Then, the UV lamp 12 can be turned on to irradiate the photosensitive resin.

[0026] A guide plate 26 is inserted into the bottom of the adjusting plate 21. The guide plate 26 is fixed to the outer wall of the cylinder 27. The cylinder 27 has two locations and is installed inside the machine housing 1. A row of connecting plates 210 is fixed at equal intervals on the outer wall of the cylinder 27. The connecting plates 210 are fixedly connected to the inner wall of the machine housing 1. A reinforcing plate 28 is connected between the two adjusting plates 21 corresponding to a UV lamp 12. A stabilizing spring 29 is connected between the reinforcing plate 28 and the cylinder 27.

[0027] As mentioned above, in the further optimized design of the adjustment component 2, the adjustment plate 21 slides more stably outside the guide plate 26, and a reinforcing plate 28 is provided between the adjustment plates 21, which has higher overall strength. Together with the stabilizing spring 29, the adjustment plate 21 has good stability when moving.

[0028] The dual-axis motor 25 is located between the two cylinders 27. The output shaft 252 passes through the inside of the cylinder 27. The flanges 251 installed at both ends of the dual-axis motor 25 are attached to the two cylinders 27 and fixed with screws. The disc 23 is also attached to the other side of the cylinder 27.

[0029] As mentioned above, the internal stability of the machine housing 1 is further optimized. The dual-axis motor 25 is connected to the two cylinders 27 through the flange 251, which makes it very stable and not easy to shake during operation. The disc 23 rotates in close contact with the cylinder 27, which also makes it very stable.

[0030] The machine housing 1 is provided with a wire opening for the wires of the dual-axis motor 25 to pass through. A protective shell 13 is installed on the side wall of the machine housing 1 to enclose the wire opening. A protective plate 14 is installed on one side of the protective shell 13, and the protective plate 14 is provided with a circular wire hole. A sealing ring 15 is glued to the inner wall of the opening through which the adjusting plate 21 passes through the machine housing 1. The sealing ring 15 is made of corrosion-resistant rubber.

[0031] Regarding the overall optimization of the robot's housing 1, the corrosion-resistant rubber sealing ring 15 bonded to the inner wall of the opening through which the adjustment plate 21 passes not only effectively prevents moisture and corrosive substances from seeping into the interior of the housing 1, protecting the safety of internal electronic components and mechanical structures, but also reduces internal pressure fluctuations caused by changes in the external environment through its excellent sealing performance. Secondly, the use of the cable port in conjunction with the protective shell 13 and the protective plate 14 effectively protects the wires of the dual-axis motor 25, preventing the wires from being worn or damaged in the complex and ever-changing pipeline environment, thereby extending the robot's service life.

[0032] In this invention, the sliding opening 24 is preferably arc-shaped. When the dual-axis motor 25 rotates forward, the stabilizing spring 29 lengthens, and the corresponding tension is transmitted to the adjusting plate 21 via the reinforcing plate 28. At this time, the adjusting plate 21 slides inward relative to the guide plate 26, while the cylindrical block 22 slides relative to each other in the sliding opening 24. Conversely, when the dual-axis motor 25 rotates in reverse, the stabilizing spring 29 is compressed, and the corresponding reverse thrust is transmitted to the adjusting plate 21 via the reinforcing plate 28. At this time, the adjusting plate 21 slides outward relative to the guide plate 26, while the cylindrical block 22 slides in the opposite direction in the sliding opening 24. In actual use, the cylindrical block 22 rotates in a circular motion relative to the axis of rotation of the dual-axis motor 25.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
