板部を切除する工具に関するものである。[Field of Industrial Application] The present invention relates to a tool for exchanging a battledore part of front and rear end stop clamps of an old line before exchanging the old and new lines of a transmission line.

っていた。2. Description of the Related Art When replacing an old line that spans several diameters with a new line, the new line is connected to the terminal of the old line and the starting end of the old line is towed by a pilot wire through a train. The detent clamps at the start and rear ends of the wire have a jumper wire attachment battledore portion, which protrudes downward and cannot pass through the gold wheel. For this reason, conventionally, a method has been used in which a cam along is attached to an old wire, is temporarily fixed to a steel tower with a wire rope, an electric wire is cut near the mouth of a retaining clamp, and a wire passing type wire clamp is attached. Although this makes towing possible, it was an aerial work that requires considerable time and labor.

るだけですむので工事は著しく簡略化される。A detent clamp comprises a linear crimp portion and a conical battledore portion at the base. A cut is made in the outer peripheral aluminum material of the battledore part and this is cut to expose the steel sleeve inside. Since the pulling force is secured at the crimping part, there is no problem with the wire extension. The work is significantly simplified because the outer skin of the battledore part only needs to be stripped off.

Prepare an arc blade tool that inserts an arcuate cut into the annular part of the battledore part. The upper and lower dies of the portable hydraulic press are first fitted with the former and then replaced with the latter to form the annular cut. After that, it can be removed manually.

It is made by shifting and covering it with pressure. Now, the side line pg is marked on the battledore portion of this aluminum sleeve, and first, a linear cut is made in the aluminum sleeve along this line, and then an annular cut is made in the annular portion including the point p.

でこのときスイッチを切替えればよい。FIG. 1 shows upper and lower tools 1 and 2 for making a notch along a line p-g mounted on the upper and lower sides of a portable press. The blades of the tools 1 and 2 are straight blades that are symmetrical and even. The blade is pressed against the p-g line from both sides, the position is changed by 2-3 degrees on the same line, and the entire length is cut. At the time of pressurization, if the blade cuts the aluminum layer and comes into contact with the steel clamp inside, the hydraulic pressure suddenly rises, so the switch may be switched at this time.

になる。Next, the tools 1 and 2 are removed and replaced with arc-shaped blade tools 3 and 4 (FIG. 2). This presses the annular part including the p point from both sides. When the arc-shaped tools 3 and 4 on both sides hit, they are located almost outside the steel clamp S, and the aluminum layer is cut off over the entire circumference. After that, it is easy to peel off the battledore part manually, and the detent clamp becomes as shown in FIG. 6 by peeling off.

It is about kg, and one or two workers can easily perform all the work. By using this tool, the battledore part can be easily cut off, and it is not necessary to replace it with the wire wheel passing type wire clamp.
