Description

Auxiliary device for indirect live-line work {AUXILIARY APPARATUS FOR INDIRECT LIVE-LINE MAINTENANCE}

The present invention relates to an auxiliary device for indirect live wire work, and more specifically, to an auxiliary device for indirect live wire work that can perform indirect live wire work by applying tension to indirect live wire equipment using a link structure and an elastic chain spring.

In the field of power distribution, work such as replacing wires is carried out in a live wire state without any power outage work. Considering the safety of workers, the indirect live wiring method was introduced. In indirect live wire work, various tip tools such as hydraulic compressors, cutters, and taping machines are mounted and used on the top of the indirect live wire stick.

Among indirect live wire equipment, muscle fatigue increases for workers due to the weight of sticks and tip tools. Also, when looking at an indirect live stick, in a situation where you have to grip below the lower insulation limit cover (red rubber packing), the moment arm becomes longer as the equipment is mounted on the end of the stick opposite to the gripping position. In particular, there is a problem in that the perceived load when fastening the compressor among the tip tools is more than 15kg, which greatly increases the muscle fatigue of indirect live wire workers and causes unstable working posture. Therefore, there is a need to improve this.

The background technology of the present invention is disclosed in Korean Patent Publication No. 10-2020-0025018 (published on March 10, 2020, title of the invention: Auxiliary device for indirect live wire work).

The wire 500 is movably mounted on the body portion 100 and the stick fixing portion 310, is connected to the spring portion 400, and transmits the tension of the spring portion 400 to the link portion 200.

10 and 11, the auxiliary device for indirect live wire work according to the present invention further includes a rotation limiter 600. The rotation limiter 600 limits the rotation of the link unit 200, maintains the angle and posture of the link unit 200, and prevents it from falling. The rotation limiting unit 600 includes a stopper unit 610 and a brake unit 620.

The stopper part 610 has one side (right side in FIG. 10) mounted on the front body portion 110 of the body portion 100, and the other side (left side in FIG. 10) is formed to be inclined downward at a set angle toward the ground, forming a link Rotation of the unit 200 beyond the set angle is restricted.

Additionally, when the link unit 200 moves downward due to cutting of the wire 500, etc., the link unit 200 comes into contact with the stopper unit 610, preventing the link unit 200 from rotating any more. Accordingly, the rotation of the indirect live stick 20 fixed to the stick support part 300 connected to the link part 200 is also restricted, thereby preventing safety accidents from occurring.

The stopper portion 610 may serve to absorb shock applied to the worker in the event of a cutting accident of the wire 500 through a buffering part separately connected to the front body portion 110.

The stopper portion 610 has a stopper groove portion 611 formed on the inside. The stopper groove portion 611 is formed to be larger than the width of the link portion 200, so that the link portion 200 can be accommodated in the stopper groove portion 611 (see FIG. 11).

The stopper portion 610 can absorb the shock applied to the worker 10 when cutting the wire 500 through a buffering part separately connected to the front body portion 110.

The brake portion 620 includes a brake body portion 621 and a brake contact portion 623. The brake unit 620 is connected to the link unit 200 and the stick support unit 300, and fixes the angle and posture of the link unit 200 through surface contact with the stick support unit 300.

The brake body portion 621 is attached to the link portion 200 and the stick support portion 300, and rotates together with the link portion 200. The brake body portion 621 fixes the angle and posture of the link portion 200 through surface contact with the stick support portion 300.

The brake contact portion 623 is mounted on the link portion 200 at the end of the brake body portion 621 (right end in Figure 10).

In the present invention, the rotation limiter 600 further includes an auxiliary brake unit 630. The auxiliary brake part 630 is connected to the link part 200 and the front body part 110 of the body part 100, and the link part 200 is connected by surface contact with the front body part 110 of the body part 100. ) fix the angle and posture.

The auxiliary brake unit 630 serves to fix the angle of the link unit 200 like or as an auxiliary to the brake contact unit 623 of the brake unit 620. The auxiliary brake unit 630 fixes the posture of the link unit 200 through surface contact with the front body unit 110 of the body unit 100.

Referring to FIG. 11, when the link unit 200 moves downward due to cutting of the wire 500, etc., the link unit 200 comes into contact with the stopper unit 610, thereby restricting the rotation of the link unit 200. Accordingly, the rotation of the indirect live stick 20 fixed to the stick support part 300 connected to the link part 200 is also restricted, thereby preventing safety accidents from occurring.

The auxiliary device for indirect live wire work according to the present invention further includes an idler (700). The idler 700 is rotatably mounted on the link unit 200. The idler 700 guides the movement of the wire 500. The wire 500 is mounted on the outer surface of the idler 700. The idler 700 rotates when the wire 500 moves and guides the movement of the wire 500.

Referring to Figures 15 and 16, the auxiliary device for indirect live wire work according to the present invention further includes a wire tube portion 800. The wire tube portion 800 is formed in a hollow shape so that the wire 500 can move, and is mounted on the rear body portion 120 of the body portion 100.

The wire tube portion 800 is formed in an inverted U shape and has a shape that surrounds the shoulder of the worker 10. The wire 500 is moved through the wire tube portion 800. By using the wire tube portion 800, the number of idlers 700 can be reduced compared to an embodiment of the present invention without the wire tube portion 800 described above.
