DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a wrapping grip remover for use in removing overhead traction grips for securing electric wires to insulators and wrapping grips for attaching branch wires to columns in overhead wire construction. It is about.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
0 and the operating rod 10
2, first raise the winding grip with the raising claw 100, then insert it into the circular ring 101, and move the circular ring 101 along the electric wire while rotating the operation rod 102, The removal of the winding grip has the following problems. There was no problem with a single binding wire, but with a bundle of several such as a wrapped grip, it would be difficult to pull up the first time due to mixed wires when protruding. It is necessary to push the tip of the driver-like raising claw into the interface between the electric wire or branch line and the binding line, and work can be performed only at a position that can be easily confirmed by eyes, and work at high places is difficult. Since the operation is performed while the operator rotates the operation rod, continuous rotation cannot be performed. It cannot be used for manipulator operation tools.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the drawbacks described in the prior art, and provides a wrapped grip remover which can be easily removed by an automatic operation in a stopped state. It is the purpose.

[0004]

SUMMARY OF THE INVENTION A winding grip remover according to the present invention is rotated by a driving force from the outside, and extends along at least the leading edge of an electric wire guide provided with an opening in an axial direction. Protruding beyond the element wire diameter, the tip portion is inclined downward, the rear end portion is provided as a guide receiver that is almost upright over substantially half a circumference, on the top surface of the tip of the unravel guide, An obtuse angle is provided, and a claw that is always in contact with the spring force is provided, and the claw is rotatable toward the unraveling guide side, but is not rotatable to the opposite side. .

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, an electric wire guide 1 which is rotated by an external driving force by a gear mechanism or the like. Has an axial opening 2 for attachment to and detachment from an electric wire or a branch line, and extends substantially halfway along the leading edge of the electric wire guide 1 and projects at least to a height equal to or greater than the wire diameter d of the winding grip. An unravel guide 4 having a guide receiver 3 having a front end portion inclined downward and a rear end portion substantially upright is provided.

As shown in FIG. 1, a claw 5 is always in contact with the upper surface of the tip of the unravel guide 4 at an obtuse angle by the spring force of a spring 6.

The pawl 5 is provided with a ratchet mechanism that is rotatable on the side of the unravel guide 4 but is not rotatable on the opposite side of the unravel guide 4. Note that in FIG.
Is a torsion lever fixed to the electric wire guide 1 so as to be located above the claw 5, and receives a winding grip rising along the claw 5 at the time of removal.
Reference numeral 8 denotes a spur gear having the same opening 2 as the wire guide 1.
The wire guide 1 is fixed to the spur gear 8, and the wire guide 1 is rotated in conjunction with the spur gear 8 when the spur gear 8 is rotated.

In practice, for example, as shown in FIG. 3, a winding grip A and a winding grip B formed by bundling five single wires preformed so that they can be wound in the left direction are provided as shown in FIG.
The case where the cable is attached to the branch line 9 will be described. In addition,
The wire end interval between the winding grip A and the winding grip B is 20 to 3
0 mm. First, unravel guide 4 of electric wire guide 1
The wire guide 1 is set on the branch line 9 as shown in FIG.

Next, when the electric wire guide 1 is rotated leftward in the twisting (tightening) side of the winding grip A, and in FIGS. 4 (a) and 4 (b), an interface between the winding grip A and the branch line 9 is formed. ,
When the unravel guide 4 bites in, the strand of the winding grip A pushes the claw 5 against the spring force and pushes open while sequentially unraveling and running on the guide 4, and when all the strands climb, As shown in FIG. 4C, the claw 5 returns to the original position. When the leading wire of the winding grip A is unraveled and reaches the guide receiver 3 of the guide 4, the rotation is stopped. In this state, the winding grip A is raised from the branch line 9 by the wire diameter d. Thus, the preparation for unraveling the winding grip A is completed.

Next, as shown in FIG. 4D, the wire guide 1 is reversed. The winding grip A is restrained between the guide receiver 3 of the unraveling guide 4 and the claw 5 and is rotated in the rewinding direction while being lifted from the branch line 9 by the element wire diameter d. As shown in FIG. 4 (e), the wire ends are removed from the branch line 9 while the diameter of the wire end is automatically increased in the radial direction by the action of the preform.

When removing the winding grip B, the unravel guide 4 of the electric wire guide 1 is positioned several cm inside the wire end of the winding grip B, and is removed in the same manner as in the case of the winding grip A. The winding grip remover of the present application does not need to be moved along the axial direction of the electric wire or branch line as in the related art, and only needs to rotate the electric wire guide 1 in a predetermined direction in a stopped state.

[0012]

As described above, the present invention has the following advantages. In the stopped state, the detachment is possible only by the rotation operation, so that the detachment can be easily performed even at a high place where it is difficult to visually confirm. It is possible to mechanically remove a winding grip having a strong fastening force having a high-strength self-locking function. Applicable as a manipulator operating tool.
