Background

In the engineering construction process, the electric pipelines are usually required to be pre-embedded in concrete, so that the condition that concrete slurry permeates into the pipelines and is solidified at the pipeline interfaces in the later threading process can occur, and the pipelines are semi-blocked or fully blocked. At present, a steel wire is adopted to dredge a pipeline, and then the pipeline is tied on the steel wire and penetrates into the pipeline.

At present, chinese patent CN201820360339.6 discloses an embedded pipe dredging machine, which uses a motor to drive a wear-resistant spring to rotate, and smashes the solidified concrete slurry in the pipeline through a wear-resistant drill bit arranged at the front end of the wear-resistant spring. The embedded pipe dredging machine is suitable for dredging straight pipes, for the internal dredging of bent pipes, the wear-resistant spring rotates forwards in the pipe, and meanwhile, the wear-resistant spring inevitably rubs the inner wall of the pipe, and non-axial compression deformation occurs in the pipe, so that the wear-resistant drill bit cannot be pushed forwards by the wear-resistant spring in the early stage of contacting with blockage, the pipe dredging is time-consuming and labor-consuming, and the progress of threading engineering is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pipeline mediation draw gear has solved the unable control spring of current pipeline mediation draw gear and has appeared the deformation problem of non-axial compression in the pipeline, improves pipeline mediation draw gear's convenient to use degree comprehensively.

In order to achieve the purpose, the utility model is realized by adopting the following technical scheme:

the utility model provides a pipeline dredging traction device, which comprises a dredging spring and a rotator, wherein the rotator is internally provided with an internal thread, the internal thread is jointed with the dredging spring in a rotating way, the tail end of the dredging spring is provided with a drill bit,

the dredging spring comprises a plurality of sections of cylindrical springs, drum-shaped springs are arranged among the cylindrical springs, and the cylindrical springs are rotationally attached to the internal threads;

the rotator is composed of two opposite clamp handles, the tail ends of the two clamp handles are hinged through a connecting shaft, the opposite sides of the two clamp handles are respectively provided with semi-cylindrical grooves which are split into two halves, the two semi-cylindrical grooves are correspondingly spliced to form a cylindrical cavity, and the internal thread is arranged on the inner wall of the cylindrical cavity.

Further, the outer diameter of the cylindrical spring is equal to the outer diameter of the drum spring end spring coil.

Furthermore, the tail end of the dredging spring is a half drum spring, and the drill bit is arranged on the half drum spring.

Further, a net-shaped grinding grain is arranged on the surface of the front end of the drill.

Adopt above-mentioned technical scheme, the beneficial effects of the utility model are that: the utility model discloses a pipeline mediation draw gear's mediation spring comprises the spring of different external diameters, can pass the department of buckling of buried pipe in a flexible way to through a plurality of drum springs constricting with the clearance of buried pipe inner wall, reduced the non-axial bending degree of cylindricality spring in buried pipe in advance, when avoiding meetting the jam, the whole mediation spring is rotatory and the friction by a wide margin of buried pipe inner wall.
