Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair traction devices, in particular to a traction device for trenchless repair of underground pipelines. Background Art

[0002] Trenchless repair of underground pipelines refers to the technology of repairing underground pipelines directly from the inside without excavation. It generally includes the following steps: (1) draining water from the damaged pipeline; (2) cleaning the sludge in the pipeline, with a focus on cleaning the damaged part of the pipeline; (3) using professional instruments to detect the damage; (4) repairing with a practical resin coating layer; (5) UV curing the repair resin; (6) conducting in-pipe inspection after construction; and (7) acceptance after water is turned on. The specific operation is to dig a first working well and a second working well on the ground at both ends of the channel to be repaired, respectively, set up a traction device near the first working well, set up a repair device in the second working well, and set up a resin coating device on the repair device. The traction device pulls the repair device through the channel to be repaired and then reaches the first working well through a pull rod, and then performs UV curing. In this way, the pipeline is repaired.

[0003] When the internal conditions of a general pipeline repair traction device are unknown, it is easily affected by the complex internal environment of the pipeline, resulting in poor repair results. At the same time, when the device is pulling the repair material, the friction between the pull rope and the wall is large, which not only increases energy consumption but may also cause damage to the pull rope.

[0004] Therefore, it is particularly important to design a traction device for trenchless repair of underground pipelines to change the above technical defects and improve overall practicality. Utility Model Content
