Description

Smart strip sheath {A smart tool to strip wire sheath}

The present invention relates to a manual smart stripping machine, and more specifically, in the process of inserting the end of the extra-high voltage wire when attempting to strip the end of the extra-high voltage wire in the process of performing live wire work. This is about a smart peeling device that allows peeling to be done quickly, easily, and safely in a short period of time without any hassle or inconvenience through a rotation method with a minimal and simple structure.

In recent years, power facilities have been expanded in response to a rapid increase in power demand, but as power users' demands for electricity quality have increased, even momentary power outages have become the subject of civil complaints, leading to an increase in collective action by electricity users such as compensation claims and cases of lawsuits. I'm doing it.

Accordingly, in order to supply quality power during distribution work, an uninterruptible method is being used in which the work is carried out in a live state without power being cut off.

In other words, the uninterruptible method means that workers can perform work while maintaining a certain distance from the transmission cable in order to prevent electric shock accidents that may occur during work such as cutting, taping, clamping, and peeling in a live wire state. It refers to a method of working using tools, etc.

In this paper, we will explain the technology of sheathing extra-high voltage wires in a live state among the uninterruptible methods.

The prior art for sheathing extra-high voltage wires in a live state as described above is as follows.

First, as published in Republic of Korea Patent Publication No. 10-1693146 (hereinafter referred to as ‘Patent Document 1’), insulation is achieved by rotating only the cutting holder built into the removable cutter part inside the casing, using a handle or electric mechanism, etc. Technologies such as a semi-automatic extra-high pressure insulation peeler capable of performing peeling work have been proposed.

In addition, as published in Republic of Korea Patent Publication No. 10-1963539 (hereinafter referred to as 'Patent Document 2'), a hydraulically operated gripper is formed on the insulating stick head at the tip of the insulating extension stick, and a hydraulic control is provided at the rear end. Technologies such as the smart indirect live wire method using plier sticks, which enables precise and safe operation of the gripper through long-distance work that secures a safe separation distance for live wire work, such as forming a hydraulic lever that operates the gripper, have also been proposed.

In addition, as published in Republic of Korea Patent Publication No. 10-1977011 (hereinafter referred to as 'Patent Document 3'), as the operating head is opened and closed through continuous rotation, the live wire is insulated and wrapped by the peeling tool. Technologies such as automatic opening and closing for possible indirect live wires have also been proposed.

However, the skinned part of Patent Document 1 not only has a very complicated technical structure in configuring the skinned part, but also it is quite cumbersome and inconvenient to hold the wire to be skinned, and in particular, it is inconvenient for the worker to handle it due to the weight of the skinned part. It has difficult drawbacks.

Patent Document 2 In addition, the technical configuration of the gripper for covering the wire is quite complex, and it has the disadvantage of increasing production costs and requiring expertise from the operator.

Patent Document 3 also has the disadvantage that, like Patent Document 1, the structure of the peeling tool for peeling the wire is quite complicated. Of course, this also has the disadvantage of being inconvenient to hold the wire and difficult for the operator to use without expertise.
