Technical Field

Background

The optical cable air blowing method (blowing cable for short) is that the optical cable is blown into a pre-buried silicon core pipe by adopting a high-pressure air flow blowing mode. The cable blowing machine blows high-pressure and high-speed compressed air into a silicon core plastic pipe (silicon core pipe for short), the high-pressure air flow pushes the air seal piston, the air seal piston connected to the end portion of the optical cable forms settable uniform pulling force on the optical cable, meanwhile, the hydraulic crawler conveying mechanism of the cable blowing machine clamps the optical cable and conveys the optical cable forwards to form conveying force, and the combination of the pulling force and the conveying force enables the penetrated optical cable to quickly pass through the pipeline in a suspension state along with the high-speed air flow.

When cable blowing work is carried out on an expressway, one cable blowing machine needs to complete a cable blowing task of 1000-2000 meters at a time, the workload is huge, and objects such as soil blocks, small stones and the like often enter the silicon core pipe, and the objects become obstacles when the cable is blown, and the more the objects are, the silicon core pipe is blocked finally, and the optical cable cannot normally run. Under the condition, a constructor usually needs to accurately calculate the blocking position of the barrier, then digs the silicon core pipe from the underground at the blocking position of the barrier, saws the silicon core pipe, and takes out the barrier, so that the cable blowing task with large workload is additionally difficult, and the working efficiency is reduced. Therefore, it is necessary to design a simple cable blowing device which can clear the obstacles in the silicon core pipe during cable blowing so as to facilitate smooth and rapid cable blowing work, especially in cable blowing work with large workload such as an expressway.
