A kind of automatic installation equipment of pre-twisted wire guard strip for electric power engineering

Abstract

The invention discloses an automatic installation device for pre-twisted wire protection wires used in electric power engineering, which includes an assembly ring, a twisting device is arranged in the assembly ring, a driving device is arranged in the assembly ring, and the end of the connecting half ring is connected with a sleeve through a detachment device. A ring is provided, and a fastening device is arranged on the sleeve ring. In the present invention, through the co-action of the sleeve ring, the threaded ring, the arc-shaped limiting plate and the inclined arc-shaped plate, the arc-shaped inner fastening plate clamps the pre-twisted wire and the cable, so that the end of the pre-twisted wire is at the In the fixed state, the power is provided by the friction between the pre-twisted wire and the driving wheel, and the rotation of the pre-twisted wire is realized under the joint action of the power bevel gear, the transmission bevel gear, the transmission shaft and the transmission gear, so that the pre-twisted wire is moving Rotation is realized during the process, so that the pre-twisted wire is helically wound on the cable to realize the installation of the pre-twisted wire protection line, and in this process, no need to operate with both hands, making the working conditions safer.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to an automatic installation device for pre-twisted wire protective bars used in electric power engineering. Background technique [0002] The transmission and distribution of electric energy is mainly realized through high and low voltage AC power grids. In the past 30 years, HVDC technology has made rapid progress, and has been more and more widely used in some power transmission fields. Therefore, as the development direction of power transmission engineering technology, the focus is on the study of UHV (above 1 million volts) AC transmission and DC transmission technology to form a larger power grid; at the same time, it is also necessary to study the technical problems of superconductor power transmission, in order to prevent overhead power. The suspension point of the line is damaged due to vibration, and the guard line is installed at the clamp of the line...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing pre-twisted wire protection line is manually rotated during installation so that the pre-twisted wire protection line is set on the cable. It is very difficult for some novices to twist the wire protection line. When the hands are working, only the feet are in contact with the cable, which is difficult to ensure the safety of the installation workers, and it is also difficult to install the pre-twisted wire protection line by rotating with both hands. Due to the disadvantage that the connection between the pre-twisted wire protection line and the cable cannot be guaranteed, a kind of automatic installation equipment for the pre-twisted wire protection line for power engineering is proposed, which can effectively realize the installation of the pre-twisted wire protection line, and Can free hands, so that the safety of installation workers can be guaranteed
