Description

Multistick for indirect live wire {MULTI-STICK FOR INDIRECT LIVE WIRES}

The present invention relates to a multistick for indirect live wiring, and more specifically, in the case of the direct live wiring method, for indirect live wiring used to prevent workers from being exposed to hazards such as electric shock in the process of directly touching a wire carrying a high-voltage current. By equipping the stick with a multi-task tool, you can perform indirect live wire work such as fastening and disconnecting bypass cable clamps, cutting jumper wires, stripping, compressing sleeves, installing and taping sleeve covers, etc. by using the multi-task tools on one stick alternately. This is about a multi-stick for indirect live wire work, which aims to prevent a decrease in work efficiency and an increase in tool purchase costs due to having sticks with different functions for indirect live wire work.

In general, live line work refers to line work performed while continuing to transmit power to a distribution line. Because the risk of safety accidents is very high, live wire work is performed in cases where it is difficult to cut off power, such as in transmission and distribution facilities, and users who work with live wires must use insulating protection or protective gear.

Live wire work on distribution lines can be divided into direct live wire work and indirect live wire work.

Direct live wire work is a method in which the user wears insulating gloves inside an insulated bucket and then directly touches the live wire. While direct live wire work is simple and saves work time, it has the disadvantage of having a high risk of electric shock, which often results in casualties.

Indirect live wire work is a method of non-contact indirect work using insulating tools such as hot sticks. Indirect live wire work takes a lot of work time, but can greatly reduce the risk of safety accidents.

Live-wire work includes inspection, repair, replacement, and cleaning of wire components such as support insulators. Depending on the type of work, direct live-wire work or indirect live-wire work can be used appropriately.

Recently, when performing new and maintenance work on distribution lines, the proportion of live line or uninterrupted work that does not interrupt the supply of electricity is increasing. In the past, there was a lot of direct live wire work in which users were in direct contact with high-voltage power lines, but the work method is currently in the process of being converted to non-contact indirect live wire work for safety reasons.

In order to perform indirect live wire work, work tools for indirect live wire work are required. However, the tools distributed in the past can only perform a small portion of indirect live wire work, so tools (sticks) must be replaced for each indirect live wire work, which increases work time and thus reduces efficiency.

Therefore, there is a need to improve this.

The background technology of the present invention is disclosed in Republic of Korea Patent Publication No. 10-1292644 (registered on July 29, 2013, title of invention: Wrench for live wire work).

Therefore, the first handle 112 and the second handle 114 can be operated to gradually open or narrow based on the hinge portion 120. Alternatively, the second handle 114 can be operated to gradually expand or narrow from the first handle 112 fixed by the hinge portion 120.

In particular, the worker performs indirect live wire work by moving the first handle 112 and the second handle 114, or the second handle 114.

At this time, the hinge portion 120 can be applied in various ways.

The first frame 132 extends from the first handle 112 with respect to the hinge portion 120, and the second frame 134 extends from the second handle 114 with respect to the hinge portion 120.

Therefore, the second handle 114 and the second frame 134 move relative to the hinge portion 120 in the opposite direction to the first handle 112 and the first frame 132.

At this time, the first frame 132 and the second frame 134 can be applied in various shapes, and can be integrally or separably coupled to the corresponding first handle 112 and second handle 114.

In particular, as an example, the second frame 134 may be hingedly connected to the first frame 132, and the second frame 134 may be hingedly connected to the second handle 114. Accordingly, when the first handle 112 is fixed and the operator pulls or pushes the second handle 114, the second frame 134 rotates with respect to the first frame 132 and can be opened or gathered. .

In addition, the multi-task tool 200 is provided on the first frame 132 and the second frame 134 so that it can be applied to multi-type indirect live wire work. Accordingly, the multi-stick 100 for indirect live wiring according to the present invention is capable of performing multiple roles required for indirect live wiring work as a single device.

In addition, the hanger 210 is open toward the worker holding at least one of the first handle 112 and the second handle 114 so that it can be pulled toward the worker while accommodating the power line 2, and has an inner side This can be formed to be curved.

Of course, the hanger 210 may be detachably coupled to at least one of the first frame 132 and the second frame 134, and may be deformed into various shapes.

Additionally, the first grab 222 is provided on one side of the first frame 132 facing the second frame 134 and serves to accommodate one side of the power line 2. In addition, the second grab 224 is provided on the second frame 134 to correspond to the first grab 222 and serves to accommodate the other side of the power line 2.

In particular, the first grab 222 is integrally or separably coupled to one side of the first frame 132, and the second grab 224 is integrated with the second frame 134 to correspond to the first grab 222. or separably combined.

So, the first grab 222 rotates with the first frame 132 with respect to the hinge portion 120, and the second grab 224 rotates with the second frame 134 with respect to the hinge portion 120. are gathered together

Accordingly, the pair of first grabs 222 and second grabs 224 are linked to the rotation of the first frame 132 and the second frame 134 and serve to surround and support the power line 2. That is, the pair of first grabs 222 and second grabs 224 are used to hold or temporarily support electric wires, jumper wires, sleeves, etc. used as the indirect live power line 2.

At this time, the first grab 222 and the second grab 224 can be transformed into various shapes.

Additionally, the first hand 232 extends from the first frame 132, and the second hand 234 extends from the second frame 134.

Therefore, the second hand 234 is linked to the rotation of the first frame 132 and the second frame 134, and moves a specific work portion of the power line 2 as it contacts or approaches the first hand 232. It plays a role in catching.

The paired first hand 232 and second hand 234 work on a specific work area of the power line 2 by performing indirect live wire work, which is difficult to do with the paired first grab 222 and second grab 224. It is used to perform indirect live wire work such as holding, fastening and disconnecting bypass cable clamps, cutting jumper wires, stripping, compressing sleeves, and attaching or taping sleeve covers.

To this end, the first hand 232 and the second hand 234, which form a pair, are interviewed or approached by one-way rotation of the first frame 132 and the second frame 134.

In particular, the first grab 222 is paired when the first hand 232 and the second hand 234 are interviewed or approached so that the first hand 232 and the second hand 234 are interviewed or approached. ) and the same-side end of the second grab 224 are spaced apart by a set distance.

Of course, the first hand 232 and the second hand 234 can be transformed into various shapes, and can be provided integrally or separately with the corresponding first frame 132 and second frame 134.

In addition, the first hand 232 and the second hand 234 may form uneven portions 235 on opposing inner surfaces, respectively. The uneven portion 235 serves to prevent slip from occurring when gripping a specific work area of the power line 2.

Then, the worker lifts the first handle 112 and the second handle 114 and performs indirect live wiring work on the power line 2 wired at the top, so that the first frame 132 and the second frame 134 can be formed relatively lightly and can be formed so that the influence of wind is reduced.

For example, at least one of the first frame 132 and the second frame 134 may pass through the edge hole 135.

Through the edge hole 135, the weight of at least one of the first frame 132 and the second frame 134 is reduced, and the influence of the wind during high-altitude work can be reduced by guiding the passage of the wind.
