Description

Technical Field

[0001] The utility model belongs to the technical field of cable installation operations, and specifically relates to a fixing device for overhead cable erection. Background Art

[0002] Overhead cable erection is an indispensable part of the power system, involving the layout, installation, and maintenance of electric wires, and is a key step to ensure the stable transmission of electricity to all regions. When carrying out overhead cable erection work, professional electric power construction personnel are required to participate. They perform precise operations at high altitudes to ensure the safety and stability of the cables.

[0003] In the erection construction of high-voltage overhead transmission lines, the whole set of erection construction methods that use the tension stringing method to string the conductors and use the technological methods coordinated with the tension stringing to carry out various operations such as tight stringing, hanging the wire, and installing accessories is called tension stringing construction.

[0004] The basic characteristics of tension stringing are as follows:

[0005] (1) The cable is in an overhead state throughout the whole process of the cable erection construction. (2) The construction section divided by the traction and tension fields is the unit project of the tension stringing construction, and operations such as tension stringing and tight stringing are carried out within the construction section. (3) The construction section divided by the traction and tension fields is not restricted by the designed strain section. It is possible to select a straight tower as the starting and ending tower of the construction section and directly string the wire on the strain tower. (4) It is possible to tighten the wire and anchor the wire on the straight tower. For any strain tower with direct stringing, it is also possible to directly tighten the wire. (5) Carry out balanced wire hanging or semi-balanced wire hanging on the strain tower with direct tight stringing. (6) The split sub-cables of the same phase are required to be strung and tightened simultaneously.

[0006] The process of cable stringing is simply to first string a small guide rope, then use the guide rope to pull and string the traction rope, and then use the traction rope to pull and string the cable. After the cable stringing is completed, the tight stringing and accessory installation work are completed.

[0007] A guy wire is a rope used to fix utility poles or electric wires, usually made of metal wire or synthetic fiber materials. They are an important part of the power transmission line, mainly responsible for fixing utility poles, supporting electric wires and the transmission line, and ensuring the normal operation of the line. Different types of utility poles need to be matched with different types of guy wires to ensure safety and reliability.

[0008] The problem of the prior art is that in traditional overhead cable erection, it requires operators to work at high altitudes. High-altitude work has a high labor intensity, is very dangerous, and requires high professional skills of personnel. Summary of the Invention
