A high-altitude cable installation mechanism with pre-tightening function

Abstract

The invention provides a high-altitude cable installation mechanism with a pre-tightening function, which relates to the technical field of cable installation. A No. 1 motor is provided, a lead head is fixedly installed at the front end of the unloading assembly, a No. 1 tightening plate is coaxially and fixedly connected to the upper end of the winding sleeve, and a fixing ring is arranged between the No. 1 fixing ring and the No. 2 fixing ring to lock In this scheme, the mounting plate is first tightened through the two No. 1 fixing rings and No. 2 fixing rings at the rear end, and the assembly is tightened by the fixing ring, so that it can be fixed on the column at one end, and then one end of the cable is tightened. Pass through the unloading assembly, the lead hole of the No. 2 tightening plate and the lead hole of the No. 1 tightening plate, and be fixed in the end lock assembly. No. 1 tightening plate can tighten the cable and prevent the cable from sagging by wrapping the cable around the spool.

Description

technical field [0001] The invention relates to the technical field of cable installation, in particular to a high-altitude cable installation mechanism with a pre-tightening function. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables and so on. They are all composed of single or multi-strand wires and insulating layers, which are used to connect circuits, appliances, etc. [0003] In the construction of offshore engineering, underwater cables are usually used in the far sea area. Compared with conventional cables, underwater cables have higher requirements for compression resistance and corrosion resistance, and the cost is also higher. Therefore, most of the projects in offshore areas and shores are still Overhead installation with conventional cables. When carryi...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a high-altitude cable installation mechanism with a pre-tightening function, which solves the problem that due to the large span of the cable and the effect of the gravity of the cable itself, it is easy to sag too much in the middle of the cable when it is installed horizontally. The shaking range is too large, which is not conducive to the stability of the cable, and the core of the cable itself is made of metal, which is very heavy and not easy to tighten
