Combined wire tightening tool for tightening conductive wire of circuit

Abstract

The invention discloses a combined wire tightening tool for tightening a conductive wire of a circuit, relates to mounting and maintaining equipment for an overhead line or cable, and is used for solving the problems of low wire tightening efficiency and damage to the conductive wire caused by insecure connection of the existing wire tightening device. The combined wire tightening tool for tightening the conductive wire of the circuit comprises a bottom plate and hoops which are arranged on the bottom plate; a rope wheel and an outer protective cover with an inverted U-shaped cross section are arranged on the bottom plate; a rotating shaft of the rope wheel extends out of the outer protective cover and is driven through a rotating disc; rolling shafts are arranged on three edges of the tail part of the outer protective cover; a roller is arranged outside each rolling shaft; the rolling shafts are arranged at the tail part of the outer protective cover of the bottom plate; the rollers are arranged outside the rolling shafts; a traction rope is arranged on the rope wheel; the traction rope extends out of the outer protective cover through the tail part of the outer protective cover. The combined wire tightening tool for tightening the conductive wire of the circuit is used for tightening the wire of the overhead line, is high in wire tightening efficiency, and can reduce the damage to a cable.

Description

technical field [0001] The invention relates to installation and maintenance equipment for overhead lines or cables, in particular to a combined wire tightening tool for line wire tightening. Background technique [0002] The transmission line on the overhead line, due to its certain span, the transmission line is often loose due to its own gravity and thermal expansion and contraction. When the length of the transmission line exceeds the specified length, it is necessary to tighten the loose transmission line. . Of course, when erecting the transmission line, it is also necessary to tighten the transmission line. [0003] In the prior art, there are mainly two kinds of wire tightening tools that are often used: the wire tightening tool disclosed by CN103594976A as the publication number, which includes a ball clamping device for connecting line wires, a second wire tightening block fixed on the pole tower, a fixed The pulley, the first wire tightening block, and the winch...

Problems solved by technology

[0003] In the prior art, there are mainly two kinds of wire tightening tools that are often used: the wire tightening tool disclosed by CN103594976A as the publication number, which includes a ball clamping device for connecting line wires, a second wire tightening block fixed on the pole tower, a fixed The pulley, the first wire tightening block, and the winch set on the ground, the operators stand on the ground and perform the wire tightening operation. The wire tightening tool disclosed in this patent includes multiple structures, and the tightening is carried out on the ground through the winch. Line operation, the power required is relatively large, and after the conversion of multiple parts, the useful work is obviously reduced after the friction loss between the traction rope and the multiple parts; One hook, wrench, sheave, one of the hooks is used to fix the wire tensioner on the tower, and the other hook is connected to the conductor through the tension clamp. Reduces damage to the wire, but the wire is not secure enough when wrapped around the strain clamp
