待望されていた。However, once the wedge has been pushed in, the wedge may be pulled out and then re-pushed in due to adjustment of the wire slackness or other circumstances. In that case, since only the pushing of the retaining clamp in the above-mentioned reference can be performed, it is necessary to prepare some other device for extracting. Since the work is performed in a high place space, there has been a long-awaited need for a clamp capable of both pushing and removing a wedge with a single device.

This arm simultaneously supports the hydraulic cylinder and presses the wedge with its piston rod. However, the U-shaped bearing is a side-open type, and allows only the side locking of the arm. On the other hand, in the present invention, instead of the U-shaped bearing, a support shaft is provided to protrude outward on both sides of the clamp. And the arm is rotatably provided on its support shaft,
The wedge is pressed on the clamp stopping side, and the wedge is pressed on the opposite side to enable removal.

る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a clamp 1 holds an electric wire with clamping pieces 1a and 1b having a C-shaped cross section facing each other. The wedges 2a and 2b are capable of filling the upper and lower gaps of the electric wire E. The wedges 2a and 2b are previously sandwiched with the electric wire E, tightened with bolts at the ears 2c, and the tips are inserted into the clamp. The clamp 1 inserts and fixes the support shaft 4 into a shaft hole 3 formed in the center of both sides and projects outward. One end of the arm 5 is locked to this. The support shaft 4 is on the diameter line of the electric wire E, and the arm 5 is rotatable in the direction of the arrow on the lower surface of the upper surface of the electric wire and has two holes 5 at the end.
a, 5b are drilled. The arm 5 is locked to the steel tower by the hole 5b. FIG. 5 shows another embodiment of the clamp 1. A hinge is provided at the top or bottom of the opposing piece of the C-shaped cross section of the clamp 1 so that either one of the hinges can be selectively coupled to facilitate attachment to the electric wire E. Next, in FIG. 4, a hydraulic cylinder C is fixed at the upper center of the retaining plate 6, and a semicircular cut 6a that can be straddled on the electric wire E is located at the lower center.
However, notches 6b into which the arms 5 can be inserted are provided on both sides thereof. The arm 5 inserted into the cut 6b has a hole 5a.
Is supported by the pin 7. A pressing plate 9 is fixed to an end of the piston rod 8 of the hydraulic cylinder C, and an adapter 9a is provided on the plate surface so as to be able to simultaneously press upper and lower wedges. This adapter has a U-shape that can be inserted into the wire E,
Press the upper wedge at the bend and the lower wedge at both leg ends.

を介在させて、アダプタ9aを押圧すればよい。FIG. 6 shows a case where the electric wire E is extended through a steel wheel (not shown) for stopping a steel tower and is temporarily fixed by a cam-along A. Attach the clamp 1 to a part of the slack electric wire behind the temporary fixing point, rotate the arm 5 toward the tower,
b is connected to the mounting bracket K and stopped on the insulator G of the steel tower.
It is locked to the retaining plate 6 by a. In this state, the oil is fed to the cylinder C, the wedge 2 is pushed by the pressing plate 9, and the electric wire can be stopped by the clamp. Then, the cam-along A is loosened to transfer the tension from the wire W to the electric wire E, and the cam-along is removed to complete this work. If it becomes necessary to remove the wedge at a stage before the removal of the cam-along, the locking of the locking plate 6 by the arm 5 is released, and the wedge pushing device of FIG. Reference numeral 5 re-locks the locking plate rotated and rotated around the support shaft 4. Then the wedge is pressed from the opposite side. If the tip of the wedge is hidden in the clamp, the adapter 9a may be pressed with an appropriate distance piece.

としたことが特徴である。As described above, wedges are all operations in a high space, as described above. Preparing another set of equipment for sampling and arranging it on the opposite side of the wedge was an unbearable labor for workers. The present invention rationalizes this point, and is characterized in that one set of pushing devices can be diverted to extraction.
