Special tool for large-angle-tower ground wire hanging installation

Abstract

The invention discloses a special tool for large-angle-tower ground wire hanging installation. The special tool comprises an inverted-U-shaped hook, two ends of the inverted-U-shaped hook are different in length, two tongue piece torsion springs are arranged in the inverted-U-shaped hook, both tail portions of the tongue piece torsion springs are fixed on inner sides of two end openings of the inverted-U-shaped hook, a removing ring is arranged on the outer top portion of the inverted-U-shaped hook, and bolts and nuts are arranged on the end portion of the long end of the inverted-U-shaped hook. The inverted-U-shaped hook is made of red copper, and the diameter of the inverted-U-shaped hook is larger than that of a wire by 2.4cm. An opened groove is formed in an inner side of the long end of the inverted-U-shaped hook, and a ground wire is fixed in the opened groove of the long end. The bolts are one-piece T-shaped bolts and are at least two in number. The end portion of the short end of the inverted-U-shaped hook is an arc-shaped inner corner. The removing ring is fixed on the outer top portion of the inverted-U-shaped hook in a single-point mode and connected with a removing insulation rope, and a hanging insulation rope is fixed at the bottom of the hook. According to the special tool for the large-angle-tower ground wire hanging installation, a novel cable clamp is designed, a catching method and opening directions after hanging are changed, accidental factors when the ground wire is hung are removed, and therefore the problem of cable clamp falling is solved.

Description

technical field [0001] The invention relates to a special tool for hanging the grounding wire of a large corner tower. Background technique [0002] With the rapid development of economic construction, the scale of power line construction is getting larger and larger, and there are more and more lines for power outage maintenance every year. In each power outage maintenance work, a permanent grounding wire needs to be hung at both ends of each power outage line. Because the 500 kV transmission line is an important power supply, the power outage time is short and the task is heavy. This requires the operator to hang up the permanent grounding wires at both ends of the power outage line in the shortest possible time and report to the person in charge of the work. Start work on the outage line. However, in the field work, especially the installation of the grounding wire of the large corner tower, the long installation time often delays the construction period and delays the ...

Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that it is extremely difficult to install and remove and easy to fall out when the horizontal distance and straight-line distance between the operating point and the attachment point are long in the installation of the grounding wire of the high-voltage line. Tool, which has the advantages of improving hooking efficiency and reducing the rate of disengagement
