Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 to 3 show a first embodiment of the present invention. FIG. 1 is a front explanatory view of a cable hanger removing device 10. In the figure, a cable hanger removal device (hereinafter referred to as a “removal device 10”) has a receiving portion 14 having an upper surface formed with an insertion gap 12 for a cable (not shown) to be inserted. The arm 14 includes two arms 16 a and 16 b extending from both sides of the arm 14, and a claw 20 provided at the tip of each arm and supported by the overhead support line 18. Figures 1 and 2
As shown in FIG. 2, the cable hanger 22 is formed of a metal line having a certain degree of elasticity, and a receiving tray 24 made of synthetic resin or the like is provided at a lower end side. The receiving tray 24 constitutes the receiving portion 14. The receiving tray 24 is formed in a substantially lip shape in a plan view such that a direction substantially orthogonal to the overhead support line 18 is a longitudinal direction, and is formed to be concave downward in an arc shape.

The two arms extending from both sides of the tray 24 are bent and deflected as shown in FIGS. 2 and 3, and their claws are provided at two separated positions on an aerial support line 18 whose ends are stretched between utility poles or the like. 20
a and 20b are elastically engaged so as to be hooked. Therefore, in the front view of FIG.
6b, the arms are spread upward on the overhead support line 18 in an inverted C-shape, the claws 20a, 20b on the tip side thereof are engaged with the overhead support line 18, and a twist of approximately 90 degrees is applied from the overhead support line. The receiving tray 24 supported by the arm is supported so that the length thereof is substantially perpendicular to the imaginary supporting line 18. A cable for communication or the like (not shown) is inserted and supported on the upper surface side of the tray.

In FIG. 1, hooks 20a and 20b are provided at the tips of the arms 16a and 16b.
One claw 20a is provided so as to be engaged in a clockwise direction with respect to the imaginary support line in the section a of the imaginary support line, and the other claw 20b is provided so as to be engaged in a counterclockwise direction. The claw engaging in the clockwise direction as viewed in the direction of arrow a is formed as a shallow hook hanging in a shallow hook shape, and the claw engaging in the counterclockwise direction is a deep claw engaging the hook deeply on the imaginary support line 18. Is formed.

In the present invention, the detaching device 10 includes a ground control rod 28 which is gripped and operated by an operator from the ground, and an operating rod 30 attached to the tip of the ground control rod 28. The ground control rod 28 may be composed of a single rod, but is preferably a telescopic rod. In the embodiment, the operating rod 30 is connected and fixed in an L shape from the ground operating rod 28. In detail, a dumbbell-shaped metal receiving member 3 having a small cylindrical portion at the center at the distal end portion of the ground operation rod 28 and an enlarged cylindrical portion whose distal end portion is larger in diameter than the small cylindrical portion.
2 is mounted and fixed via a support cylinder 48, and a screw hole 36 formed with a screw groove is formed in a vertical direction from the center of the upper surface side of the metal fitting 32. The operating rod 30 is fixed by screwing a fixed shaft 37 extending vertically from the base 34 of the operating rod 30 into the screw hole 36. Thus, by rotating the ground operation rod 28 about the longitudinal axis, the operating rod 30 is also integrally rotated in the same direction. A small cylindrical portion, which is the outer periphery of the cylindrical receiving member 32, has a hollow cylindrical base portion 44 of a guide portion 42 described later.
Are provided so as to be able to rotate freely around the longitudinal direction.

In the embodiment, more specifically, the lower end of the horizontal U-shaped base 34 is screwed and fixed to the screw hole 36, and the upper end of the horizontal U-shaped base 34 is slightly upward and zigzag in plan view. It is connected to and fixed to the operating rod 30 via a bent portion 38 that is bent in a shape (FIGS. 2 and 3), and supports the operating rod 30. A locking rod 40 is fixed to the horizontal U-shaped base 34 so as to straddle the U-shaped concave opening. Thereby, the base of the operating rod 30 is reinforced, and the insertion stop positioning when the tip of the operating rod 30 is inserted into the insertion gap 12 on the upper surface of the tray 24 is performed. This locking rod 40
Instead of being fixed so as to straddle the U-shaped concave portion, the U-shaped base 34 may simply be provided so as to protrude from the upper end side to the lower side and the leading end is opened.

The operating rod 30 is rotated about the axis orthogonal to the aerial support line 18 while penetrating through the insertion gap 12 of the cable hanger 22 and is simultaneously moved to both arms 16a and 16b of the cable hanger. Forcibly rotate in the same direction while locking, and hook 2 of cable hanger
0a and 20b are separated from the overhead support line 18. FIG. 1 shows a state in which the operating rod 30 is inserted into the insertion gap 12 by a guide portion 42 described later, and the operating rod 30 is substantially parallel to the overhead support line 18. By turning the ground operation rod 28 clockwise from this state, the operating rod 30 also rotates clockwise. However, the operating rod 30 corresponds to the shape of the lip-shaped tray 24 of the receiving portion 14. From the state of engagement with the receiving portion, it can be naturally raised upward along its edge, and when the force is applied most as shown in FIGS. 2 and 3, the operating rod 30 is applied to both arms 16a and 16b. They will be engaged at the same time. The deep claw 20b is hooked to the imaginary support line counterclockwise and hooked to the imaginary support line 18 and the shallow claw 20a is hooked clockwise to the imaginary support line 18 when viewed in the direction of arrow a in FIG. , The operating rod 30 is simply moved to both arms 16.
a and 16b are rotated rightward while penetrating through the insertion gap 12, and both claws 20a,
0b is almost simultaneously separated from the aerial support line (strictly, the shallow nail side comes off first). In this case, the operating rod 30
The cable hanger is removed while the distal end of the cable hanger is engaged with the shallow claw side.

The direction in which the operating rod 30 is inserted into the insertion gap 12 is not limited to the case shown in FIG. 1, but also when the operating rod 30 is inserted through the insertion gap from the opposite direction, the operating rod is similarly rotated clockwise in plan view. Thus, the cable hanger 22 can be easily detached from the aerial support line 18. For example, FIG.
In the example of No. 5, when the operating rod is inserted into the insertion gap 12 and rotated clockwise to apply the most rotational force, the base side of the operating rod 30 is engaged with the arm 16a on the shallow claw side to perform the detaching operation.

As described above, when the operating rod 30 is inserted into the insertion gap 12 from the opposite direction, the operating rod 3 is configured such that the distal end of the operating rod 30 abuts on the arm 16b of the deep claw 20b.
The base portion of the cable hanger 22 is engaged with the arm 16a on the shallow claw side to forcibly detach the cable hanger 22. Operating rod 3
The reference numeral 0 may be a structure in which the base side is simply fixed and connected in an L-shape from the ground operation rod, and the same operation and effect can be obtained.

In the embodiment shown in FIGS. 1 to 3, the detaching device 10 has a guide portion 42 through which the operating rod 30 can be inserted into the cable insertion gap 12 along the overhead support line 18. In FIG. 1, the guide part 42 is a substantially L-shaped suspension body 4.
The base 44, which is the lower end of the L-shape, is supported idly on the distal end of the ground control rod 28, and its upper end is suspended from an overhead support line. That is, the suspension body 46 has the hollow cylindrical base portion 44 that is loosely fitted to the dumbbell-shaped fitting 32 fixed on the support tube 48 at the tip of the ground operation rod 28. That is, the base 44
A metal wire extends in an L-shape so as to bypass the base 34 of the laterally U-shaped operating rod 30, and an inverted U
A curved portion 45 having a character shape is formed. A concave bottom portion 45a whose opening is directed to the lower surface of the inverted U-shaped bent portion 45 is placed on the upper surface of the overhead support line 18, whereby the support tube 48 is suspended when the suspension body 46 is suspended by the overhead support line. As a result, the entire ground operation rod 28 that idles and engages is suspended from the overhead support line. Therefore, even when the operating rod 30 is not inserted through the insertion gap 12, the upper end of the ground operating rod 28 is
It can be suspended and supported.

As a result, the suspension 46 is connected to the overhead support line 1.
The operating rod 30 is easily inserted into the insertion gap 12 simply by sliding along the longitudinal direction of the aerial support line 18 in a state where the operating rod 30 is suspended from the support rod 8. Will be greatly improved. Moreover,
Since the tip of the ground operation rod 28 can be slid in a state of being suspended by the suspension body 46, the operator operating on the ground can
Since the force for supporting the entire operation rod of the operator is light, the operation labor at the time of operation can be greatly reduced. Thus, the operating rod 3 is simultaneously attached to the two arms of the cable hanger.
The cable hanger can be easily removed from the aerial support line simply by rotating the operating rod 30 about the axis orthogonal to the aerial support line 18 while engaging the engagement of the cable hanger 22. The work can be realized in a very short time and with a simple operation.

When the cable hanger 22 is detached from the aerial support line 18, the cable hanger is slightly scattered from the longitudinal direction of the aerial support line in a predetermined angle direction due to the elastic engaging force of the cable hanger to the aerial support line. By simply picking up and collecting this, the overall work efficiency can be greatly improved. In the embodiment, arrow a
Support line 18 in the counterclockwise direction with the deep claw 20b side in the direction
, And the shallow claws 20a are hooked clockwise, but the deep claws 20b are engaged clockwise,
Similarly, when the shallow claws 20a are engaged in the counterclockwise direction, both claws can be disengaged from the aerial support line by rotating the operating rod clockwise in plan view. Unlike the embodiment, when the cable hanger is formed by bending the claws in the opposite direction at the time of molding, the operating rod 30 only needs to be rotated counterclockwise in plan view. .

FIGS. 4 and 5 show a second embodiment of the detaching apparatus according to the present invention.
Only the operation rod 30 is directly fixed in an L-shape from the upper end of the first embodiment. That is, the operating rod 30
Is simply rotated to the left in a plan view in a state of being penetrated into the insertion gap 12 between the two arms 16a and 16b, and the shallow claw 20a is detached first just by forcibly applying a turning force, and almost simultaneously from the overhead support line. The entire cable hanger will come off. In this case, the cable hanger is removed while the base end of the operating rod 30 is engaged with the shallow pawl side.
