Embodiment Construction

[0009] The whole string of insulator tools for the tension-resistant line of the big knife card live replacement line according to the present invention, such as figure 2 As shown, it includes a housing 1, an inner chamber 2 is provided in the housing 1, four first buffer rods 3 are fixedly installed on the upper part of the inner chamber 2, and the first guide rod 66 of each first buffer rod 3 extends out of the housing. 1 travel motor 40 is installed outside, and travel sheave 4 is installed on the output shaft of travel motor 40. For convenience, the replacement insulator tool is suspended on the overhead line by the walking sheave 4, such as Figure 5 and Figure 6 As shown, all the running sheaves 4 are located at the front top of the housing 1. Such as figure 2 As shown, the lower part of the inner cavity 2 is symmetrically installed with two barrier-crossing brackets 28 with the central axis of the inner cavity 2 as the midline. Such as figure 2 and Figure 6 S...

Abstract

The invention discloses a tool with a large knife clamp for lively replacing a strain insulator string on line, comprising a shell; an internal chamber is arranged in the shell; four first damping rods are fixedly arranged at the upper part of the internal chamber; a first guide rod of each first damping rod extends out of the shell so as to assemble a walking motor; an output shaft of each walking motor is provided with a grooved pulley that is arranged above the front upper part of the shell; a positioning device of the tool for replacing an insulator string is arranged at the back part of the shell; the positioning device is hinged with a connecting plate; an U-shaped wire clip is arranged on the connecting plate; a position-limited slot is arranged on the U-shaped wire clip; the U-shaped wire clip is hinged with a hydraulic cylinder; a piston rod of the hydraulic cylinder is fixedly connected with an insulating rod; the insulating rod is hinged with one end of a large knife clamp wire clip; the other end of the large knife clamp wire clip is provided with a positioning hook; three positioning screw holes are arranged on the side wall of the large knife clamp wire clip; a turnover driving motor is arranged on a turnover hinging seat; and an output shaft of the turnover driving motor is connected with a hinging shaft of the turnover hinging seat and the connecting plate.

Description

technical field [0001] The invention relates to a tension-resistant whole string insulator tool for live replacement lines with a big knife card. Background technique [0002] At present, in the ultra-high voltage power transmission and transformation industry, there are great potential safety hazards in the process of using existing tools to replace double L series insulators and double V series insulators. The main reason is that it needs at least two workers to cooperate to replace the insulator string with the existing tools, and, because the installation position of the insulator is that one end of the insulator is close to the wire tower, and the other end is installed away from the wire tower, therefore, at least one A staff member must leave the wire tower completely and carry out high-altitude operations under the condition that the whole body is suspended on the transmission line. The safety of the operation is low, and the transmission line is prone to breakage, c...
