Description

Technical Field

[0001] The utility model relates to the technical field of tying head structures, in particular to a tying head structure for repairing ultraviolet light-cured pipelines. Background Art

[0002] Ultraviolet light curing repair technology refers to a pipe repair method in which glass fibers are woven into a tube, impregnated or injected with resin, and then pulled into the original pipe. Under the action of ultraviolet light, the tube is cured to form a liner with a certain strength to achieve the purpose of pipe repair and reinforcement. At present, this technology has been more and more widely used in sewage pipes, rainwater pipes, gas pipes, etc. The fixing method of the tying head in the prior art is simple. During the bundling and dragging of the lining hose, the connection between the lining hose and the tying head will slide significantly. This sliding will seriously affect the sealing of the lining hose. Secondly, this method reduces the accuracy of the light curing position and reduces the service life of the product. Secondly, the setting will cause the light curing pipeline to be scrapped.

[0003] Chinese patent document CN210831004U discloses a piercing head for UV light curing repair, including a bracket, the bracket including a first annular bracket, a second annular bracket arranged inside the first annular bracket, a first block arranged in an array on the bracket, an adjusting screw arranged in an array on the bracket, the adjusting screw including a screw body, and a second block arranged in an array on the bracket. The above device has defects in the piercing head for UV light curing repair. The device first needs to rotate the adjusting screw three times to fix the second block to the light curing pipe for the first time, and then rotate the adjusting screw three times to fix the first block to the lining pipe. This method requires six operations, which is complicated and increases the repair time. Secondly, there is no linkage between the adjusting screws, which easily makes the pipe to be repaired not in the center position, thereby causing repair failure. Utility Model Content
