Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a supporting device for a pipeline ultraviolet light curing repair lamp stand. Background Art

[0002] Ultraviolet light-cured pipe repair technology (UV-CIPP) is an innovative repair method. It uses a pull-in method to pull a compacted and treated fiberglass hose into the existing pipe, inflate it, and expand it to fit snugly against the existing pipe. The existing pipe serves as the outer membrane, and the inner membrane of the hose serves as the inner membrane. The resin is then cured under the action of ultraviolet light from a mobile lamp, forming a composite liner with a certain strength. This is a complete pipe repair technology. However, UV-curing repair methods have limitations on pipe shape and size. UV-curing pipe repair is not suitable for pipes with complex shapes and severe structural defects, such as bends, variable cross-sections, and those crossing obstacles and undulating areas. Therefore, a support device for the UV-curing pipe repair lamp is urgently needed to solve these problems. Utility Model Content

[0025] As Figure 2 shown, elastic movable leg includes pipe column 43, spring two 44, supporting leg 45 and universal wheel 46, pipe column 43 is fixed to the outside end of mounting rod 41, the upper end of supporting leg 45 slides into pipe column 43, spring two 44 is fixed between mounting rod 41 and supporting leg 45, and universal wheel 46 is at least provided with one and is installed at the outer end of supporting leg 45;Preferably, supporting leg 45 is herringbone-shaped, universal wheel 46 is provided with two, and two universal wheels 46 are installed on the two sides of the outer end of supporting leg 45, to strengthen the stability when supporting device moves.

[0026] As Figure 1-4As shown, the end of the connecting column 2 away from the connecting plate 1 has a threaded head 3 integrally formed therewith, and both ends of the ultraviolet lamp 6 are provided with a convex threaded groove 61, and the threaded head 3 is threadedly connected to the threaded groove 61; the outer wall of the connecting column 2 is provided with at least a pair of notches 21, and the notch 21 is installed with an elastic limiter, the outer end of the elastic limiter extends out of the notch 21, and an annular limit hole 62 is provided at the edge of the threaded groove 61, and the outer end of the elastic limiter abuts against the limit hole 62; the elastic limiter includes a spring 22 and a limit block 23, the spring 22 is fixed in the notch 21, the limit block 23 is inserted into the notch 21 and fixedly connected to the spring 22, and the inner end of the limit block 23 is limited in the notch 21, and the outer end extends out of the notch 21;

[0027] In this embodiment, when the supporting device is installed, Figure 1-2 As shown, first fit the two circular connecting plates 1 together, and make the side grooves 11 on the two connecting plates 1 correspond one to one, insert the mounting rods 41 on the movable legs 4 into two of the communicating side grooves 11, and then insert the bolts 13 into the through holes 12. The bolts 13 will pass through the mounting holes on the mounting rods 41, and then tighten the bolts 13 to fix the mounting rods 41 on the two connecting plates 1. The remaining movable legs 4 are also installed one by one in the remaining side grooves 11 according to the above operations. The installation operation is simple and it is convenient to install multiple movable legs 4 on the two connecting plates 1.

[0028] Then install the UV lamp 6 on the supporting device, Figure 2-4 , screw the connecting column 2 and the threaded head 3 into the threaded groove 61 at one end of the ultraviolet lamp 6, and press the limit block 23 into the notch 21 before the limit block 23 enters the limit hole 62. At this time, the spring 1 22 is compressed. When the notch 21 enters the threaded groove 61, it is loosened, so that the limit block 23 is pressed against the inner wall of the limit hole 62 under the elastic force of the spring 1 22. In order to facilitate the limit block 23 to easily enter the limit hole 62, a chamfered corner is made at one end of the limit block 23 near the limit hole 62, so that the staff does not need to manually press the limit block 23. After the limit block 23 is screwed into the limit hole 62, the limit The inner wall of the hole 62 will exert an extrusion force on the limit block 23. Since the spring 1 22 has elastic force, the spring 1 22 will be compressed after the limit block 23 is subjected to torsion, so that the limit block 23 can enter the limit hole 62; the threaded connection between the thread head 3 and the thread groove 61 connects the ultraviolet lamp 6 and the connecting column 2 together, and after the limit block 23 is completely inserted into the limit hole 62, the limit block 23 always presses against the inner wall of the limit hole 62, thereby strengthening the connection strength between the ultraviolet lamp 6 and the connecting column 2, and effectively preventing the ultraviolet lamp 6 and the connecting column 2 from being separated by external force when the ultraviolet lamp 6 is in use. The installation operation is simple and easy to operate.

[0029] If the ultraviolet lamp 6 needs to be separated from the support device in the later stage, the ultraviolet lamp 6 can be separated from the support device in the reverse order of the above-mentioned installation operation of the ultraviolet lamp 6 and the connecting column 2, which is simple and convenient to operate.

[0030] During the use of the support device and the ultraviolet lamp 6, the plurality of annularly distributed movable legs 4 of the support device make the support device have a plurality of stress points in the pipeline 5, so that the plurality of movable legs 4 of the support device smoothly slide under the traction of the rope, and better support and transport the ultraviolet lamp 6;

[0031] If a curved section of the pipeline 5 is encountered, the universal wheel 46 in the movable leg 4 can automatically turn along with the movement of the support device, and the rotating disc 42 can also rotate in the side groove 11, so that it can flexibly walk in the curved section of the pipeline 5;

[0032] If the support device moves to a variable cross-section of the pipeline 5 or an obstacle inside the pipeline 5 makes the inside of the pipeline 5 undulating, the universal wheel 46 is pressed, the universal wheel 46 and the supporting leg 45 can be extruded together with the spring 44, the spring 44 is elastically deformed, and at the same time, the universal wheel 46 can also make a turning action on the supporting leg 45, and the rotating disc 42 rotates in the side groove 11, so that the support device can smoothly pass through the variable cross-section of the pipeline 5 or the pipeline 5 with obstacles;

[0033] Therefore, the problem that the ultraviolet light curing pipeline repair device is not convenient to pass through the pipeline 5 with serious complex shape and structural defects is solved.
