ADSS optical cable and iron tower connecting device

Abstract

The invention discloses an ADSS optical cable and iron tower connecting device, which aims to solve a defect that the stability of an iron tower is affected due to a great horizontal pulling force imposed on the iron tower by an ADSS optical cable when being installed on the iron tower. The ADSS optical cable and iron tower connecting device comprises a connecting rod, two adjusting rods with thelength being adjustable which are respectively connected at two ends of the connecting rod and pulling rings connected on the adjusting rods respectively, wherein the two pulling rings are respectively connected to supporting rings used for being installed on the iron tower, the pulling rings are movably hooked on the supporting rings respectively, each pulling ring is connected with a pre-twistedwire in a tightened manner, each pre-twisted wire is connected with an ADSS optical cable, and the two pre-twisted wire tightens the connecting rod. The ADSS optical cable is installed on the iron tower through a force unloading device, thereby greatly reducing the horizontal pulling force for the iron tower, reducing influences imposed on the stability of the iron tower, and being conducive to prolonging the service life of the iron tower.

Description

technical field [0001] The invention relates to an ADSS optical cable installation auxiliary device, more specifically, it relates to a connection device between an ADSS optical cable and an iron tower. Background technique [0002] At present, the ADSS optical cable is erected along with the electric power tower, and the optical cable is fixed to each level of iron tower through fittings. The iron towers at both ends and the middle corner tower use tension-resistant fittings to hold the ADSS optical cable to withstand the running tension of the optical cable. The straight line tower in the middle is suspended by hanging fittings Hang the ADSS optical cable without bearing the running tension of the optical cable. For the iron tower, the smaller the horizontal tension of the ADSS optical cable is, the better. Excessive tension will affect the stability of the iron tower. Now we can only rely on adjusting the tightness of the optical cable to reduce the tension on the iron to...

AI Technical Summary

Problems solved by technology

[0004] The invention overcomes the disadvantages that when the ADSS optical cable is installed on the iron tower, the horizontal pulling force on the iron tower is relatively large, which affects the stability of the iron tower, and the ADSS optical cable is prone to excessive sag after long-term use, and provides an ADSS optical cable and Tower connection device, the ADSS optical cable is installed on the iron tower through the connection device, which greatly reduces the horizontal tension on the iron tower and reduces the impact on the stability of the iron tower, and the ADSS optical cable can automatically adjust the length of the connection device when the arc sag is too large, so that Tighten the ADSS optical cable to reduce the sag of the ADSS optical cable, so that the ADSS optical cable is not prone to excessive sag
