Weak-current cable threading device and threading lead and application method thereof

Abstract

The invention relates to a weak-current cable threading device and a threading lead and an application method thereof, and relates to the technical field of weak-current cable threading. The weak-current cable threading device comprises a reel bracket, a threading lead and a lead head, wherein the reel bracket includes a triangular base, an annular outer ring frame, an annular inner ring frame, arotating shaft and a U-shaped limiting pipe, and the U-shaped limiting pipe is provided with an oil brushing device and an oil supply device. The cross section of the threading lead is provided with agroove, the groove is arranged along the length direction of the weak-current cable in a full length mode, the end of the threading lead is provided with an external thread, the lower end of the leadhead is provided with an internal thread matched with the external thread, the lead head is screwed on the threading lead, and the center of the lead head is provided with a threading hole. The weak-current cable threading device not only realizes fast threading, but also prevents the weak-current cable from being damaged in the threading process; and the improved reel bracket can complete the automatic oil brushing process, and the oil brushing piece can be detached, so that the built-in sponge can be replaced regularly.

Description

technical field [0001] The invention relates to the technical field of weak current threading, in particular to a weak current cable threader, its threading wire and its use method. Background technique [0002] At present, the pipelines of weak current cables generally go underground. During construction, the pre-embedded pipes are first laid underground, and the cable wells are constructed. After the pipeline project is completed, the weak current cables are inserted into the pre-embedded pipes. Due to the long distance between the cable wells, the threading process is generally carried out with a threader. refer to figure 1 , the existing threader includes a threading wire 2 and a spool support 1, the end of the threading wire 2 is provided with a lead head 3, the head of the threading thread 2 is provided with a perforation 31, and the threading thread 2 is wound into a coil and placed on the bobbin support 1 Inside; the spool support 1 includes a triangular base 11 , ...

AI Technical Summary

Problems solved by technology

Since the weak current cables are not protected during the threading process, the weak current cables are easily worn at the corners of the cable wells and pre-embedded pipes, causing damage to the weak current cables
