[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhead wire pulling wheel used for laying wires, cables and the like overhead.

[0002]

2. Description of the Related Art When wires and cables are laid overhead,
Conduct wire drawing work on wires, cables, etc. through an overhead wire drawing wheel. Conventionally, such an overhead wire drawing wheel is mounted on a supporting column such as a steel tower or a power pole, for example, as shown in FIG. Wire rope for overhead extension line with rope, bind line 12, etc.
13 was installed, and the work was performed by a person on the support pillar 10.

[0003]

As described above, since the conventional wire-drawing wheel is mounted on a scaffold for elevating a supporting column such as a steel tower or a telephone pole with a rope or a binding wire, the fixed interval is fixed. In the case of the elevating scaffold, it was not possible to attach the wire pulling wire to any position on the support pillar. In addition, since the wheel is not fixed securely, the wheel swings during the wire drawing work of the wires and cables, and the wires and cables may come off from the drawing rollers mounted in the wheel and damage the wires and cables. is there.

[0004] Furthermore, the work of attaching the wire drawing wheel to the support post is performed by the worker ascending to the support post, so that it takes time and effort to fix and remove the wheel and there is a problem in workability.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and provides an overhead wire drawing wheel which can be easily and securely fixed to an arbitrary position of a support column. An aerial wire-drawing metal wheel integrally provided with a metal wheel fixing belt attached thereto, wherein the metal wheel fixing belt has a belt fixing fastener and a belt separating device, and the belt separating device is The lock plate includes a connection plate, an engagement pin, and a lock plate. The lock plate is mounted with a separation / removal ring, and is rotated and moved by operating the separation / removal ring.
In other words, the engagement with the engagement pin provided on the binding plate is released.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view of an overhead wire drawing wheel according to the present invention. FIG. 1 (a) is a side view and FIG. 1 (b) is a front view.
As shown in the figure, a belt fixing fastener 1 such as a buckle is fixed to one end of the belt 2, and the belt 2 and the belt 3 are connected by a separating device 4. Then, the end of the belt 3 is inserted into the fastener 1 fixed to the belt 2 and fixed to the support column. A wire drawing wheel 5 is fixed to and integrated with the belt 2.

FIG. 2 is a detailed explanatory view of the separation device 4. FIG. 2 (a) is a side view, FIG. 2 (b) is a front view, and FIG. 2 (c) is X ₁ -X _{1 of} FIG. It is an arrow view. In the drawing, reference numeral 41 denotes a separation device main body, which is attached to an end of the belt 3 by pins 48. Reference numeral 42 denotes a connecting plate, which is attached to the end of the belt 2 and is engaged with an engaging pin 44 provided on the connecting plate 42 by a lock plate 43 provided on the separating device main body 41 via a spring 45. , Belt 2 and belt 3 are connected. Reference numeral 46 denotes a separation / removal ring, which is mounted in a through hole 43a formed in a lower protruding portion of the lock plate 43. When the ring 46 is pulled down with an operation rod or the like pulled out from the ground, the lock plate 43 is separated from the separation device. Rotational movement parallel to the main body 41, the engagement with the connection plate 42 is released,
The belt 2 and the belt 3 are separated.

FIG. 3 is a detailed explanatory view of the gold wheel 5, and FIG.
Is a front view, FIG. 3 (b) is X ₂ -X ₂ arrow view of Figure (b). In the drawing, reference numeral 51 denotes a frame on which an extension roller 55 is mounted, and 52 denotes a mounting seat having a certain degree of inclination with respect to the frame 51, which is integrally mounted on the belt 2 via a connector 56. Reference numeral 53 denotes a lock plate, and reference numeral 54 denotes an opening / closing plate for attaching the wheel 5 to electric wires and cables.

[0009]

FIG. 4 is an explanatory view showing a state in which the overhead wire pulling wheel of the present invention is mounted on a support pole such as a telephone pole. FIG. 4 (a) is a front view, and FIG. 4 (b) is a rear view. The fixing belt consisting of the belts 2 and 3 connected by the separating device 41 is fixed to the supporting column 10 such as a telephone pole by using the belt fixing fastener 1 fixed to one end thereof.
Tighten and fix at any position. It is preferable to use a fastener with a return prevention device as the belt fixing fastener 1. At this time, since the mounting wheel 52 having a certain inclination with respect to the wheel frame 51 is integrally attached to the wheel 5, when the belt is tightened and fixed to the supporting column 10 as described above, And the wheel 5 are kept substantially parallel. And
Release the lock plate 53 and open the open / close plate 54 to open the wheel frame 51.
An electric wire and a cable are inserted into the inside, and positioned on the extension roller 55, the opening / closing plate 54 is closed, and the lock plate 53 is locked.
In this state, wire and cable extension work is performed.

When the wire and the cable of the present invention are removed after the wire and the cable have been drawn, the separation / removal ring of the separation device 4 is pulled down with an operation rod or the like pulled out from the ground.
As a result, the lock plate 43 of the separation device 4 is
The belt 2 and the belt 3 are rotated in parallel with each other, the engagement between the lock plate 43 and the connecting plate 42 is released, and the belts 2 and 3 are separated at this portion and can be removed.

As described above, in the overhead traveling wire wheel of the present invention, the belt to which the wheel 5 is fixed is fastened and fixed to the supporting column, so that the wheel can be easily fixed to an arbitrary position of the supporting column. It is possible to improve the work of installing the wheel in the wire drawing work. In addition, since the wheel is securely fixed to the support column as described above, the wheel does not swing during wire and cable extension work, and the wire and cable may come off from the extension roller and be damaged. Not even. Further, as described above, by remotely operating the belt separating device from the ground, it becomes possible for the worker to easily remove the wheel without climbing to the support pillar.

[0012]

As described above, according to the overhead wire pulling wheel of the present invention, the belt is fastened and fixed to the support column, so that the support column can be arbitrarily set regardless of the lifting platform of the support column. Can be easily attached to the position of the wheel, which is extremely effective especially when used for a support column without a scaffold for lifting. Also, since the wire and the cable are securely fixed to the support pillar, the wheel does not swing when the wire or the cable is extended, and the wire or the cable does not come off the extension roller and is not damaged. Further, by providing the fixing belt with a separating device so that the fixing belt can be separated in the longitudinal direction, it becomes possible to remove the wheelbarrow by remote control from the ground.
