Sweeper for dredging underground pipeline

Abstract

The invention belongs to a power cable laying device, in particular to a clearing device for dredging the underground pipeline. According to the technique proposal provide by the invention, the clearing device for dredging the underground pipeline includes a center positioned device, a clearing device, and a driving mechanism that drives the clearing device to rotate. The invention is characterized in that a plurality of flexible connecting arms are arranged at the outer wall of a rotator in the clearing mechanism; a clearing hammer is arranged at the outer end of each connecting arm. The clearing hammer includes a tube part which is used to be connected with the tube shape connecting arm, and a head part with the function of collision. The head part is bigger than the tube part. The tube part is provided with a tube space for the connecting arm to insert in; and the outer end of the connecting arm is inserted in the tube space. The power cable laying device of the invention can expediently clear the inner wall of a pipeline, thus avoids the damage to the power cable by the thorn on the inner wall of the pipeline.

Description

technical field [0001] The invention belongs to equipment for laying power cables, in particular to a cleaner for dredging underground pipelines. Background technique [0002] The laying of power cables generally adopts the laying methods of pipe laying, tunnel laying, direct burial laying, underwater laying, and the combination of the above methods. Among them, trench laying, tunnel laying and underwater laying are mainly suitable for some special areas. At present, the most commonly used laying methods under urban roads are direct burial and piping. With the increase of investment in urban construction and the long-term planning of the city, direct burial laying will gradually be replaced by pipe laying methods with better applicability. [0003] Pipeline laying is an installation method of laying cables in pre-built underground pipelines. It is suitable for areas with relatively heavy urban traffic, crowded underground corridors, and a large number of laying lines. [0...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the construction site generally dredges the pipes by manpower pulling plastic rods. The disadvantages of this dredging method are: large loss and relatively large restrictions on the length of the pipes

With the gradual promotion of non-excavation technology, the length of some river-crossing pipes is too long, and the current rods cannot be used at all, which makes it difficult to dredge the pipes and affects the quality of cable laying.
