Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for gripping an electric wire and a spacer using the same, and an object thereof is to facilitate work at a high place.
[0002]
【Example】
The drawings will be described. In FIG. 1, the main body 1 and the arm 2 have a semicircular recess capable of gripping an electric wire facing the center, and the left end is pivotally attached by a pin 3. The main body 1 is provided with a spring chamber 1a having an open front and rear surface on the right side, and a spring 4 is accommodated therein. The arm 2 is provided with a clevis 2a on the right side. (FIG. 2).
The spring support 5 is formed by welding the disc 5b to both legs of the U-shaped plate 5a, and is inserted into the upper space of the spring 4 in the spring chamber. The disc 5b has a central hole 5c. (Figure 3). The T-shaped bolt 6 has a rectangular head 6a and can pass through the clevis 2a of the arm when the direction is adjusted.
In FIG. 1, this T-shaped bolt engages with the clevis, freely passes through the opposite side of the main body and the spring 4, and is screwed into the nut 7 in the U-shaped plate 5a. A push bolt 8 is screwed onto the top wall of the spring chamber, and its tip can press the top of the U-shaped plate 5a.
[0003]
[Action]
The case where an electric wire is removed from this apparatus holding the electric wire as shown in FIG. 1 will be described. First, the push bolt 8 is turned to slightly reduce the spring 4 together with the spring bracket 5. Since the T-shaped bolt 6 is rotatable, its head direction is matched with the clevis 2a direction of the arm. The arm 2 comes out and hangs down and separates from the electric wire. It is obvious from the above when the electric wire is attached.
In this device, the length of the main body 1 is lengthened, and a plurality of presser arms 2 are pivotally attached at appropriate intervals to form a spacer capable of gripping a plurality of electric wires. FIG. 5 is an illustration of a three-wire spacer provided with three arms 2.
[0004]
【The invention's effect】
In the present invention, the spring bracket 5 is inserted between the push bolt 8 and the spring 4. If the push bolt 8 is pushed, only the spring 4 is pushed, and the T-bolt 6 becomes independent of the spring pressure. Therefore, the operator can easily turn 90 degrees of the bolt angle with the fingertip. On the other hand, there is no conventional wire gripper (for example, Japanese Utility Model Publication No. 51-78395) that corresponds to the spring bracket 5. Therefore, referring to FIG. 1 of the present invention, the conventional product directly pushes the upper end of the T-shaped holt 6 with the push bolt 8. The spring 4 is compressed by this pressing, and the friction at both ends of the spring increases. 90-degree turning of the T-bolt 6 increases the difficulty. The use of hand tools was inevitable. Most of the gripping or releasing of the electric wire is a suspended work on a high-altitude power transmission line. Whether or not a manual tool (spanner) is necessary is a problem that is of great interest to the operator. In the case of the present invention, a screw wrench for the push bolt 8 is always required, but a swirl wrench for the T-bolt 6 with spring pressure is not necessary. Significantly reduce the burden on high-altitude workers.
