Embodiment 1

[0013] Embodiment 1. A pre-twisted wire installation jig is characterized in that: it comprises a split-type left shell 6 and a right shell 5; the left shell 6 and the right shell 5 are docked to form a sleeve by a locking mechanism, The central hole of the sleeve is a round hole; the outer surface of the sleeve is provided with a pre-twisted wire 7 fixing mechanism. The open-close left shell 6 and the right shell 5 and the locking mechanism are as follows: a hinge joint 4 is provided between the left shell 6 and the right shell 5, and the left shell 6 is provided on the sleeve. The buckle 1 docked with the right shell 5. How to use: Connect the left shell 6 and the right shell 5 to form a sleeve, and put it on the transmission wire 8 . The locking mechanism of the left shell 6 and the right shell 5 is butted with the buckle 1 through the hinge joint 4 . The locking mechanism can also use belts or pipe clamps to connect the left shell 6 and the right shell 5. The fixing mech...

Embodiment 2

[0014] Embodiment 2: A pre-twisted wire installation jig is characterized in that it includes an openable left shell 6 and a right shell 5; the left shell 6 and the right shell 5 are butted to form a sleeve through a locking mechanism, The central hole of the sleeve is a round hole; the outer surface of the sleeve is provided with a pre-twisted wire 7 fixing mechanism. The outer surface of the upper part of the sleeve is a conical surface 2 . The fixing mechanism of the pre-twisted wire 7 is a casing 3, and there are two casings 3 fixed on the left casing 6 and the right casing 5 respectively. How to use: connect the left shell 6 and the right shell 5 through a locking mechanism to form a sleeve, and put it on the power transmission wire 8. The locking mechanism can be a belt or a pipe collar. The pre-twisted wire 7 fixing mechanism can be a casing, and the end of the pre-twisted wire 7 is inserted into the casing to fix it, so that the pre-twisted wire 7 is wound and repaire...

Abstract

The invention discloses a pre-twisted wire installation clamp and belongs to the technical field of devices of fastening wires. The pre-twisted wire installation clamp is characterized by comprising an opening and closing left pipe shell and an opening and closing right pipe shell. The left pipe shell and the right pipe shell are connected in an abutted mode through a locking mechanism to form a sleeve. The center hole of the sleeve is a round hole. A pre-twisted wire fixing mechanism is arranged on the outer surface of the sleeve. The outer face of the upper portion of the sleeve is a circular conical surface. The pre-twisted wire fixing mechanism is composed of two casing pipes which are fixed on the left pipe shell and the right pipe shell respectively. A hinge joint hinge is arranged between the left pipe shell and the right pipe shell. A snap joint which makes the left pipe shell and the right pipe shell be connected in the abutted mode is arranged on each casing pipe. The clamp can be installed on a power transmission line in a butt joint and sleeved mode, so that the head portion of a pre-twisted wire is inserted into the casing pipes and firmly fixed. The circular conical surface forms a tapered head portion. A ladder assembly sheave hung to the power transmission line can be conveniently moved from the clamp, the labor intensity can be reduced and the overhauling quality of the power transmission line can be ensured.

Description

technical field [0001] The invention relates to a fixture for installing pre-twisted wire, which belongs to the technical field of wire fastening appliances. Background technique [0002] The maintenance of broken strands of transmission wires is an important maintenance work. The transmission maintenance regulations require that the damage rate of the wires is 25%, and pre-twisted wires and protective wires need to be wound on the transmission wires for repair. When the wire is broken, it needs to be wound and repaired with twisted wire. When the twisted wire is deformed, uneven and not tight during winding, it will cause heating, arcing, corona, and even wire breakage. Neat and tight winding of pre-twisted wire and guard wire is one of the effective methods to reduce wire corona. Therefore, it is necessary to take correct and effective maintenance process measures in the maintenance of damaged and broken strands of the transmission wire, so as to ensure the normal operati...
