Cable wear tractioned cavity cleaning device

Abstract

The invention discloses a cable wear tractioned cavity cleaning device comprising a main shaft. The two ends of the main shaft are respectively provided with a cable connector and a traction connecting head. The main shaft is provided with a support plate, and the circumference of the support plate is provided with rolling wheels. The main shaft is also provided with a cavity cleaning plate which is connected with the main shaft in a sliding manner. The cavity cleaning plate is provided with a driving arm; the driving arm is provided with a driving wheel; the driving wheel is arranged on the side with the exterior edge located outside of the cylindrical face formed during the rotation of the cavity cleaning plate. The invention is mainly used for laying underground power cables. It can not only be applied in large areas but it is also convenient to construct. With the functions of thorough cleaning, it is not easy to be jammed and can run smoothly. At the same time, for different cable pipes, all that needs to do is replace the cavity cleaning plate according to specific requirement, without the need to be equipped with a number of cavity cleaning plates, thus saving construction costs.

Description

technical field [0001] The invention belongs to the technical field of power cable laying construction tools, and in particular relates to a device used as a cable pulling head to clean the inner cavity of a cable pipe when underground power cables are laid through pipes. Background technique [0002] In the construction of electrical equipment, when the cables pass through buildings, obstacles and other places where the cables are easy to be damaged, it is necessary to bury the cable tubes underground so that the cables pass through the tubes to protect the cables. According to the requirements of construction standards, the inner cavity of the cable tube must be clean and free of debris. Existing construction of cables through pipes is generally guided by a gyro-shaped metal traction head, and the two ends of the traction head are respectively connected to the pull wire and the cable; During the running process, push the sundries in the threading pipe to run, and drive th...

AI Technical Summary

Problems solved by technology

Existing problems: First, the traction head is relatively bulky, the pulling resistance is large, and labor-intensive; especially when encountering debris attached to the pipe wall, it is easy to jam and work efficiency is low; second, the push-type cable The diameter of the tractor head for pipe cleaning is fixed. It is inconvenient to use the corresponding tractor head for different specifications of cable tubes. Moreover, it is difficult to grasp the size of the tractor head. The diameter of the puller head is larger. Although the cleaning effect is better, the It is easy to jam, resulting in poor operation; on the contrary, using a small diameter traction head, although the operation is smooth, but there will be dead corners, which will cause the problem of unclean cleaning; third, the cleaning area of ​​the inner wall of the cable tube can only reach half , it is difficult to meet the requirements of the construction standards for cable pipe penetration
