Description

Technical Field

[0001] This utility model belongs to the field of pipeline repair technology, specifically relating to a pipeline photocuring repair device. Background Technology

[0002] Ultraviolet curing trenchless repair technology refers to a pipeline lining repair technology that uses mechanical traction to pull a felt hose impregnated with photosensitive resin into the pipeline to be repaired, injects compressed air to make it adhere tightly to the inner wall of the pipeline, and uses ultraviolet light to cure the resin inside the pipeline, forming a high-strength inner resin lining new pipe, in order to achieve the purpose of pipeline repair.

[0003] For example, Chinese Patent Publication No. CN214008487U discloses a special ultraviolet lamp for trenchless pipeline photocuring repair, comprising two discs. The discs are fixedly connected by a connecting shaft. The outer peripheral wall of the connecting shaft has a mounting groove, within which the ultraviolet lamp is installed. The connecting shaft is covered by a transparent, openable protective cover. A square column is fixedly connected to the side of the discs away from the connecting shaft, and the square column has a telescopic device with a moving mechanism. A power supply is fixedly connected inside the connecting shaft. This device can adapt to pipes of different diameters and allows for easy replacement of the ultraviolet lamp.

[0004] As described in the prior art of the aforementioned patent, the lining is cured in the pipe by irradiation with ultraviolet light. However, the angle between the ultraviolet lamp and the pipe is fixed, which results in some parts of the lining being directly irradiated by the ultraviolet lamp while others are not. The intensity of the irradiated light on the lining varies, resulting in different curing effects. Utility Model Content

[0005] The purpose of this invention is to provide a pipe light curing repair device that can adjust the irradiation angle of the ultraviolet lamp on the lining, thereby improving the uniformity of the light intensity received by the lining.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A pipe photocuring repair device includes two sets of vehicle body mechanisms arranged front and rear, with mounting frames rotatably mounted on the two sets of vehicle body mechanisms, and ultraviolet lamps mounted on the sides of the mounting frames; each vehicle body mechanism includes a center plate, with support leg mechanisms mounted on the sides of the center plate, and rollers mounted on the support leg mechanisms; and rotating shafts are respectively provided at both ends of the mounting frames.

[0008] In a preferred embodiment, a central hole for inserting a rotating shaft is provided through the center of the central plate, and the central axis of the central plate coincides with the central axis of the central hole.

[0009] In a preferred embodiment, the outer side of the outer bushing of the rotating shaft is provided with a lug, and the lug is provided with a quick-release bolt for fixed connection with the center plate.

[0010] In a preferred embodiment, the rotation of the mounting bracket is driven by a drive motor. The outer end of the output shaft of the drive motor has a polygonal structure. One end of the central shaft of the rotating shaft has a socket for inserting the drive shaft of the drive motor. Two quick-release bolts are inserted through the outer side of the drive motor for fixing it to the center plate.

[0011] In a preferred embodiment, the outrigger mechanism includes a support rod 1 fixedly connected to the center plate, a support rod 2 telescopically disposed within the support rod 1, and a locking rod 1 passing through the outer side of the support rod 1 away from the center plate.

[0012] In a preferred embodiment, a traction rope is provided on the outer side of the center plate of each group of vehicle body mechanisms.

[0013] The technical effects achieved by this utility model are as follows:

[0014] When the vehicle body mechanism of this utility model moves inside the pipeline carrying the ultraviolet lamp, the mounting bracket can be adjusted to rotate, thereby driving the ultraviolet lamp to rotate and adjust. By rotating the ultraviolet lamp, the irradiation position of the ultraviolet lamp on the lining can be changed, so that the intensity of ultraviolet lamp irradiation received by all parts of the lining is uniform and consistent, thus improving the curing effect of the lining.

[0015] This practical mounting bracket can be flexibly disassembled and quickly assembled with the vehicle body mechanism. It can be flexibly disassembled and assembled according to the usage environment and transportation needs, improving the ease of use of the device. Attached Figure Description

[0024] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Please see the appendix Figures 1 to 3 As shown, this utility model provides a pipe light curing repair device, including two sets of vehicle body mechanisms 1 arranged front and rear. The two sets of vehicle body mechanisms 1 are rotatably equipped with mounting frames 2, and ultraviolet lamps 3 are installed on the side of the mounting frames 2. The vehicle body mechanism 1 includes a center plate 11, and a support leg mechanism 4 is installed on the side of the center plate 11. Rollers 5 are provided on the support leg mechanism 4. The two ends of the mounting frame 2 are respectively provided with rotating shafts 21, and the outer side of the center plate 11 of each set of vehicle body mechanisms 1 is respectively provided with traction ropes 6.

[0028] When repairing the pipeline, the curing device is placed inside the pipeline to cure the lining that was placed in the pipeline in advance. When the vehicle body mechanism 1 carries the ultraviolet lamp 3 along the pipeline, the ultraviolet lamp 3 is driven to rotate along the rotating shaft 21 by the drive motor 22, so that the relative position between the ultraviolet lamp 3 and the lining can be adjusted, so that the irradiation intensity of the ultraviolet lamp 3 on the lining is more uniform and the curing effect of the lining is better.

[0029] When the vehicle body mechanism 1 of this utility model moves inside the pipeline carrying the ultraviolet lamp 3, the mounting bracket 2 can be adjusted to rotate, thereby driving the ultraviolet lamp 3 to rotate and adjust. By rotating the ultraviolet lamp 3, the irradiation position of the ultraviolet lamp 3 on the lining can be changed, so that the intensity of ultraviolet lamp 3 irradiation received by all parts of the lining is uniform and consistent, thus improving the curing effect of the lining.

[0030] Preferably, in this embodiment, the movement of the device within the pipeline is achieved by the pulling of the traction ropes 6 at both ends of the two sets of vehicle body mechanisms 1.

[0031] The device moves within the pipeline by relying on the support leg mechanism 4 to support the rollers 5 as they roll on the inner wall of the lining, i.e., the inner wall of the pipeline.

[0032] Please refer to the following: Figures 2 to 5 As shown, a central hole 111 for inserting a rotating shaft 21 is provided through the center of the central plate 11, and the central axis of the central plate 11 coincides with the central axis of the central hole 111; an ear piece 211 is provided on the outer side of the outer bushing of the rotating shaft 21, and a quick-release bolt 212 is provided on the ear piece 211 for fixed connection with the central plate 11; the rotation of the mounting bracket 2 is driven by the drive motor 22, the outer end of the output shaft of the drive motor 22 has a polygonal structure, and a insertion hole 213 for inserting the drive shaft 221 of the drive motor 22 is provided at one end of the central shaft of the rotating shaft 21, and a quick-release bolt 222 is provided on the outer side of the drive motor 22 for fixed connection to the central plate 11; the support leg mechanism 4 includes a support rod 41 fixedly connected to the central plate 11, a support rod 42 is provided telescopically inside the support rod 41, and a locking rod 43 is provided through the outer side of the support rod 41 away from the central plate 11;

[0033] In this embodiment, the assembly or disassembly of the vehicle body mechanism 1 and the ultraviolet lamp 3 can be carried out on the ground or underground. During assembly, the rotating shafts 21 at both ends of the ultraviolet lamp 3 are first inserted into the center holes 111 of the center plates 11 of the two sets of vehicle body mechanisms 1. Then, the quick-release bolts 212 of the lugs 211 on the rotating shaft 21 are screwed into the threaded holes pre-drilled in the center plate 11 to fix the outer bushing of the rotating shaft 21 and the center plate 11. Then, the drive shaft 221 of the drive motor 22 is inserted into the rotating shaft 21 with the insertion hole 213. Then, the quick-release bolts 222 on the housing of the drive motor 22 are screwed into the threaded holes pre-drilled in the center plate 11 to fix the drive motor 22 and the center plate 11.

[0034] Then, the support rod 41 and support rod 42 in the support leg mechanism 4 are extended and retracted to make the overall length of support rod 41 and support rod 42 meet the inner diameter requirement of the pipe, so that the roller 5 contacts the inner wall of the liner, and then the support rod 41 and support rod 42 are locked by tightening the locking rod 43.

[0035] The drive motor 22 is powered by an external control device. The power supply line can be set along the traction rope 6 and tied to the traction rope 6 to prevent the power supply line from being pulled too much and breaking.

[0036] After installation, the central axis of the center plate 11 of the two vehicle body mechanisms 1, the central axis of the drive shaft 221 of the drive motor 22, the central axis of the rotating shaft 21, and the central axis of the mounting bracket 2 should be on the same straight line to make the concentricity of the equipment stronger.

[0037] The working principle of this utility model is as follows: When repairing a pipeline, the curing device is placed inside the pipeline to cure the lining that has been placed inside the pipeline in advance. When the vehicle body mechanism 1 carries the ultraviolet lamp 3 and moves along the pipeline, the ultraviolet lamp 3 is driven by the drive motor 22 to rotate along the rotating shaft 21, so that the relative position between the ultraviolet lamp 3 and the lining can be adjusted, so that the irradiation intensity of the ultraviolet lamp 3 on the lining is more uniform and the curing effect of the lining is better.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
