Note that an improved invention relating to the bundling tool (gripping tool) as described above is described in, for example, Patent Document 1.

Japanese Patent Application Publication No. 11-278108

The work of attaching and bundling the bundling tool shown in Figure 9 and the bundling tool described in Patent Document 1 to the power line is carried out using a rail-mounted vehicle, ladder, or aerial vehicle for high-altitude work, and as all of these involve high-altitude work, there is always a risk of falling.
Although work using a road-rail vehicle is safer than work using a ladder or aerial platform, there is a problem that work using a road-rail vehicle cannot be done in places where the feeder wire is far from the track or where other facilities are installed. Also, there are cases where the two feeders to be worked on are far from each other, in which case a separate work is required to bring the two feeders closer together.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a tool for installing a bundling tool for electric wires, which can be operated only on the ground without working at height, and can attach a bundling tool to an electric wire to bundle two electric wires.
Another object of the present invention is to provide a tool for attaching a feeder wire bundling tool that can easily bring two feeder wires close to each other and bundle them together even when the two feeder wires are separated from each other.
Another object of the present invention is to provide a method for bundling two feeder cables with high efficiency by using a feeder cable bundling tool.

In order to achieve the above object, the present invention provides
A tool for attaching a feeder cable bundling tool is used to bundle two feeder cables that are suspended from a support structure and laid in a pair, using a bundling tool having a pair of semi-tubular restraining members connected by a hinge,
a first tool attached to a tip of the first control rod for bringing two separated feeder conductors closer to each other;
a second tool attached to a tip end of a second operating rod, for attaching the bundling tool to the two adjacent feeder wires in a state in which the pair of semi-tubular restraining members are open, and for rotating the pair of semi-tubular restraining members to close them and inserting a connecting pin into the tubular portion at the end opposite to the hinge,
The second tool is
a connecting member connected to a tip end of the second operating rod and having a male screw portion protruding upward;
a base member rotatably attached to the connecting member via a bearing member;
a pair of guide rods fixed to the base member so as to extend upwardly in parallel with each other;
A holding member that is movable up and down along the guide rod and can hold a bundling tool;
a wire receiving member fixed to the upper end of the pair of guide rods and extending in a horizontal direction;
a closing means for closing the pair of semi-tubular restraining members of the bundle fitting held by the holding member in an open state in response to the rotation of the second operating rod;
a pin pushing means for inserting a connecting pin into a predetermined portion of the end portion opposite to the hinge in a state where the pair of semi-tubular restraining members are closed;
and a hook member rotatably attached to the base member and having a locking portion to which one end of the first rope is locked.

According to the above-mentioned means, the first tool attached to the tip of the first operating rod brings two separated electric power lines closer together, and the second tool attached to the tip of the second operating rod attaches an open bundling tool to the two close electric power lines, closes the semi-tubular restraining member, and inserts a connecting pin into the tubular part at the end opposite the hinge. These operations can be performed only from the ground, so the operation of bundling two electric power lines with a bundling tool can be safely performed without working at height.

Here, preferably, the second tool includes a tension spring for biasing the holding member upward, and when the first rope is pulled, the hook member is rotated in a hook release direction, and the holding member is moved upward by the spring force of the tension spring.
the blocking means is disposed between the base member and the holding member, and includes a slide member having a nut portion screwed into the male thread portion of the connecting member and a pair of pressing pins protruding upward, the slide member being movable up and down along the guide rod,
The slide member is configured to rise in response to rotation of the second operating rod, raising the pair of pressing pins and rotating them in a direction in which they come into contact with the pair of semi-tubular restraining members and close.

This configuration allows the second tool to be constructed compactly with a small number of parts. In addition, by pulling the first rope downward, the hook member is released and the holding member can be moved upward by the spring force of the tension spring, and the second operating rod is rotated to raise the slide member, pushing up the pressure pin and causing it to come into contact with and block a pair of semi-tubular restraining members of the bundling tool, allowing the two feeder wires to be easily and reliably bundled together by the bundling tool.

Further, preferably, the pin pushing means comprises a push pin arranged movably on the same axis as the connecting pin of the bundling tool, a compression spring for pressing the push pin forward, and a storage pipe incorporating the push pin and the compression spring, the storage pipe being fixed to a predetermined portion of the electric wire housing member,
An operation pin is fixed to the push pin and protrudes in a direction perpendicular to the axis of the push pin.
The storage pipe is formed with a spiral groove through which the operation pin is inserted,
one end of a second rope is engaged with the operating pin, and when the second rope is pulled, the lock is released and the push pin moves in a direction protruding from the storage pipe by the spring force of the compression spring, so that the connecting pin is inserted into a predetermined portion of the end of the pair of semi-tubular restraining members opposite the hinge,
One end of a third rope is hooked to the holding member.

This configuration allows the pin pushing means to be constructed compactly with a small number of parts, and when the second rope is pulled downward, the push pin is projected, allowing the connecting pin to be securely inserted into the tubular portion at the end opposite the hinge of the semi-tubular restraining member of the bundling tool. In addition, since one end of the third rope is engaged with the holding member, the holding member can be lowered by pulling the third rope downward after inserting the connecting pin into the bundling tool, and the second tool can be easily removed from the feeder wire.

Also, preferably, the first tool is
a main body frame rotatably attached via a bearing member to the connecting member connected to the tip end of the first operating rod in a state in which the male screw portion protrudes upward;
an upper roller attached to an upper portion of the main body frame so as to be rotatable about a horizontal axis;
A pair of guide rods extending from an upper portion of the main body frame in parallel with the rotation axis of the upper roller;
a holding frame screwed into the male thread portion of the connecting member;
a lower roller rotatably supported by the supporting frame around a horizontal axis of rotation;
One end of the rotating shaft protrudes outward from the holding frame, and the protruding portion is configured to be in contact with a side surface of the main body frame and to be slidable thereon, thereby preventing the holding frame from rotating relative to the main body frame.
According to this configuration, when the two feeders are separated by a relatively short distance, the two feeders can be easily brought close to each other so as to be in contact with each other by the first tool.

Alternatively, the first tool may include:
A U-shaped holder connected to an upper end of the first operating rod;
A guide hand rotatably mounted on a horizontal shaft fixed to the holder;
a roller rotatably mounted on the horizontal shaft;
A pair of hook rods each having a downward hook at its tip and extending horizontally forward from an upper portion of the guide hand;

Below, an embodiment of the feeder cable bundling tool installation tool according to the present invention will be described with reference to the drawings. The feeder cable bundling tool installation tool according to the present invention is designed as a tool suitable for use when attaching a bundling tool 40 as shown in FIG. 9 to a feeder cable, and comprises a first tool 10 for bringing two paired feeder cables closer together when they are separated, and a second tool 20 for bundling the two approaching feeder cables with the bundling tool. Furthermore, the first tool 10 includes tool A, which is used when the two feeder cables are close to each other at a point where the distance between them is small, and tool B, which is used at a point where the distance between the two feeder cables is relatively large.

1 and 2 show an embodiment of a first tool 10A, FIGS. 3 and 4 show an embodiment of a first tool 10B, and FIGS. 5-8 show an embodiment of a second tool 20. As shown in FIG.
First, an embodiment of a first tool 10A will be described with reference to FIGS.
1A is a plan view of the first tool 10A of the present embodiment, FIG. 1B is a side view thereof, and FIG. 1C is a front view thereof. FIG. 2 shows a procedure for using the first tool 10A.

As shown in FIG. 1B, the first tool 10A includes an L-shaped main frame 12 attached to the upper end of an insulating operating rod 34, an upper roller 14 rotatably attached to a horizontal shaft 13 fixed to the upper part of the main frame 12, a pair of guide rods 15A, 15B extending from the upper part of the main frame 12 in parallel with the horizontal shaft 13, a U-shaped holding frame 16 screwed into a male threaded portion 11a formed on the upper part of a connecting sleeve 11 fitted to the upper end of the operating rod 34 and connected by a pin, and a pair of cylindrical lower rollers 18A, 18B rotatably mounted around horizontal shafts 17A, 17B held by the holding frame 16.

One end of the horizontal shafts 17A, 17B that serve as the rotation axis of the lower rollers 18A, 18B protrudes to the outside of the holding frame 16 (to the left in FIG. 1), and the protruding portion is configured to be in contact with the side surface of the vertical side portion 12a of the main frame 12 so as to be slidable, and is configured to prevent the holding frame 16 from rotating relative to the main frame 12. In addition, a bearing (bearing member) 19A such as a sliding bearing is interposed between the lower horizontal side portion 12b of the main frame 12 and the connecting sleeve 11, and a nut 19B that screws into the male thread portion 11a formed on the upper portion of the connecting sleeve 11 is fixed to the center of the holding frame 16, and when the operating rod 34 is turned, the connecting sleeve 11 and the male thread portion 11a rotate, causing the nut 19B and the holding frame 16 to rise or fall relative to the main frame 12.

The guide rods 15A, 15B have a bent portion 15a on the base end side, i.e., the side closer to the holding frame 16, which is bent so as to form a recess toward the upward direction, and a hanging portion 15b on the tip end side, i.e., the end farther from the holding frame 16, which is bent downward.
In addition, an auxiliary rod 15C is provided between the guide rods 15A and 15B to prevent deformation while maintaining a constant distance between the guide rods 15A and 15B.

The first tool 10A is an effective tool when the distance between the two feeders W1, W2 is small. The worker operates the control rod 34 to position the guide rods 15A, 15B so that they are placed on the two feeders W1, W2 as shown in FIG. 2(A), and then moves them forward (to the left in the figure) to engage the recesses formed by the bent portions 15a of the guide rods 15A, 15B with the feeders W1, W2 close to each other as shown in FIG. 2(B). The control rod 34 may also be supported by a tripod.

Then, turn the operating rod 34 to rotate the male screw portion 11a. This causes the holding frame 16 to rise, and as shown in FIG. 2(C), the lower rollers 18A, 18B approach the upper roller 14, pinching the feeder wires W1, W2 and preventing them from coming out of the recesses. Next, pull the operating rod 34 in the direction in which the feeder wires extend, and move the upper first tool 10A to a position where the bundling tool is attached. This brings the two separated feeder wires closer together, and the bundling tool shown in FIG. 9 can be attached to the feeder wires W1, W2, making it possible to easily set the state in which the work of bundling the feeder wires W1, W2 can be performed.

Next, an embodiment of the first tool 10B used to bring two feeders closer together when they are relatively far apart will be described with reference to Figs. 3 and 4 .
3A is a plan view of the first tool 10B of this embodiment, FIG. 3B is a side view thereof, and FIG. 3C is a rear view thereof. FIG. 4 shows a procedure for using the first tool 10B.

As shown in FIG. 3, the first tool 10B includes a holder 111 connected to the upper end of an insulating operating rod 34, a guide hand 113 rotatably attached to a horizontal shaft 112 that is hung between a pair of vertical support pieces 111a formed on the upper part of the holder 111, a roller 114 rotatably attached to the horizontal shaft 112, a pair of hook rods 115A, 115B that have downward hooks F1, F2 at their tips and extend horizontally forward (to the right in the figure) from the upper part of the guide hand 113, a locking portion 116 provided at the tip of the hook rods 115A, 115B, and a rope 117 that has one end fixed to the locking portion 116, is in contact with the upper part of the roller 114, and is wound around the rope 117 so as to change direction 90 degrees downward.

The hook rods 115A and 115B are mounted so as to be slidable in the axial direction by a holder 118 attached to the upper part of the guide hand 113. The guide hand 113 has a protruding piece 113a protruding forward from the lower part, and this protruding piece 113a and the hook rods 115A and 115B are configured to form a storage recess capable of storing two electric power feeders.
The locking portion 116 includes a pin 116a that locks one end of the rope 117, and also has the function of maintaining the distance between the hooking rods 115A and 115B. A retaining member 119 that maintains the distance between the hooking rods 115A and 115B and has a retaining function is connected to the rear ends (the left ends in the figure) of the hooking rods 115A and 115B.

The first tool 10B is an effective tool to use when the distance between the two feeder conductors W1, W2 is relatively large, and the worker operates the operating rod 34 to move the hooking rods 115A, 115B above the lower of the two feeder conductors W1, W2 (W1 in the figure) as shown in FIG. 4(A) and position the hooks F1, F2 at their tips so as to hook onto the higher feeder conductor (W2 in the figure).
Next, the operating rod 34 is pulled down to bring the hooking rods 115A and 115B into contact with the upper part of the feeder wire W1 as shown in Fig. 4(B) At this time, the guide hand 113 rotates, and the hooking rods 115A and 115B tilt.

Then, the rope 117 is pulled to move the hooking rods 115A and 115B backward, and as shown in FIG. 4(C), the two feeder wires W1 and W2 are held side-by-side by the hooks F1 and F2 and the protruding piece 113a of the guide hand 113. This allows the bundling tool in FIG. 9 to be attached to the feeder wires W1 and W2, making it easy to bundle the feeder wires W1 and W2 together.

Next, an embodiment of the second tool 20 used for attaching a bundling tool to two feeder wires and bundling them together will be described with reference to Figs. 5 to 8.
Fig. 5(A) is a front view of the second tool 20 of this embodiment, Fig. 5(B) is a side view thereof, and Fig. 6 is a plan view thereof. Figs. 7 and 8 show a procedure for using the second tool 20.

As shown in FIG. 5, the second tool 20 of this embodiment includes a connecting sleeve 21 that is fitted and pin-connected to the upper end of an insulating operating rod 34, a base member 22 that is rotatably mounted via a bearing 22a at the middle position of the connecting sleeve 21, a pair of parallel guide rods 23A, 23B that are fixed to the rear of the base member 22 so as to extend upward, and a slide member 24 that has a nut portion that is screwed into a male screw portion 21a formed on the upper part of the connecting sleeve 21. When the operating rod 34 is turned, the connecting sleeve 21 and the male screw portion 21a rotate, and the slide member 24 can be moved up and down.

The second tool 20 also includes a bundle tool holding member 25 located above the slide member 24 and movable up and down along the guide rods 23A and 23B, a pair of tension springs 26A and 26B for biasing the holding member 25 upward, a pair of horizontally J-shaped electric wire storage plates 27A and 27B fixed to the upper ends of the guide rods 23A and 23B and extending horizontally forward (to the right in the figure), a beam member 28 spanning between the upper ends of the guide rods 23A and 23B, and a hook member 29 rotatably attached to the base member 22 by a pin shaft 29a.

The holding member 25 is provided with a pair of L-shaped gripping plates 25a, a connecting pin 25b that is horizontally connected between the L-shaped gripping plates 25a, and a pair of cylindrical parts 25c that are fixed to the rear end of the gripping plates 25a and slidably engage with the guide rods 23A and 23B. The holding member 25 is configured to grip the bundled tool (see FIG. 9) by clamping the pin of the hinge 42 of the bundled tool from both sides with a pair of tightening screws 25d that are screwed into the tip of the pair of gripping plates 25a. In addition, the holding member 25 is provided with a rope locking piece 25e, and one end of a rope 31 is connected to this locking piece 25e, so that the holding member 25 can be moved downward by pulling the rope 31 downward.

Further, the pair of tension springs 26A, 26B are stretched between the vicinity of the cylindrical portion 25c of the holding member 25 and the beam member 28. Further, the hook at the tip of the hook member 29 can be engaged with the engaging piece 25e, and one end of a rope 32 (see FIG. 7) is connected to an engaging portion 29b provided at an intermediate position of the hook member 29, so that when the rope 32 is pulled downward, the hook is released and the holding member 25 is raised by the tension of the tension springs 26A, 26B.
The hook member 29 is constantly biased forward by a tension spring 29c stretched between it and the base member 22. When the rope 31 is pulled downward to move the holding member 25 downward, the connecting pin 25b comes into contact with the hook at the tip of the hook member 29 and temporarily releases it to the outside, and when the holding member 25 is further lowered, the hook member 29 rotates due to the tension spring 29c and is automatically locked.

The slide member 24 has a pair of guide pieces 24c that protrude rearward (to the left in the figure), and the side surfaces of these guide pieces 24c contact the outer peripheral surfaces of the guide rods 23A, 23B from the inside, thereby allowing the slide member 24 to move in the vertical direction.
In addition, a pair of pressure pins 24b protruding upward are attached to the slide member 24 in a positionally adjustable manner, and the positions and spacing of the pressure pins 24b are set so that the tips of the pressure pins 24b can abut against the central outer periphery of the semi-tubular restraint member that constitutes the bundle joint.

Furthermore, as shown in FIG. 6, in the wire storage plate 27A constituting the second tool 20, one end of a storage pipe 30 which protrudes laterally is fixed to a position above the tip of the gripping plate 25a of the holding member 25, and this storage pipe 30 contains a push pin 30a and a compression spring 30b which presses the push pin.
An operating pin 30c is fixed to the push pin 30a and protrudes in a direction perpendicular to the axis of the pin, and a spiral guide groove is formed in the storage pipe 30 to guide the operating pin 30c, with one end of a rope 33 being engaged with the operating pin 30c. When the rope 31 is pulled downward, the push pin 30a rotates and is unlocked, and the spring force of the compression spring 30b pushes the push pin 30a so that it moves to protrude from the storage pipe 30, and presses the connecting pin of the bundle metal fitting (40) held by the holding member 25 and pushes it into the cylindrical portion.

Next, a method of using the second tool 20 will be described with reference to FIGS.
The second tool 20 is a tool used to attach a bundling tool to two feeder wires brought close together by the first tool 10A or 10B and bundle them together. When using this tool, first, as shown in Fig. 7(A), the sliding member 24 and the holding member 25 are positioned downward, and the hinge pin of the bundling tool 40 is clamped by the tightening screw 25d of the holding member 25 to hold the bundling tool 40 in a state in which the semi-tubular restraining member is opened.

Then, the electric wires W1, W2 are stored in the recesses of the electric wire storage plates 27A, 27B, and then the rope 31 is pulled to release the hook at the tip of the hook member 29, and the tension of the tension springs 26A, 26B causes the holding member 25 to rise as shown in FIG. 7(B) and the hinge of the bundling metal fitting 40 to contact the center of the lower surface of the electric wires W1, W2. Next, the operating rod 34 is turned to raise the slide member 24, and the tip of the pressing pin 24b is brought into contact with the lower surface of the semi-tubular restraining member of the bundling metal fitting 40 as shown in FIG. 8(A).

Thereafter, when the operating rod 34 is turned to raise the slide member 24, the pressure pin 24b pushes up and rotates the semi-tubular restraining member of the bundling metal fitting 40, so that the two cylindrical portions of the bundling metal fitting 40 overlap (their centers are aligned) as shown in Figure 8 (B).
Here, when the rope 33 is pulled and the operating pin 30c is rotated 90 degrees, the push pin 30a is unlocked and the push pin 30a is pushed out by the spring force of the compression spring, pressing the connecting pin 43 of the bundling metal fixture 40 held by the holding member 25 and pushing it into the cylindrical portions 44A to 44C. As a result, the feeder wires W1 and W2 are bundled together by the bundling metal fixture 40.

Thereafter, the operating rod 34 is turned in the opposite direction to lower the slide member 24, and when it has reached a predetermined position, the rope 31 is pulled to lower the holding member 25, causing the hook member 29 to rotate and automatically lock due to the tension spring 29c, and the tip of the operating rod 34 is moved rearward (leftward in FIG. 8) to remove the electric wire housing plates 27A, 27B from the electric wires W1, W2. Next, the first tool 10A or 10B is removed from the electric wires to complete the work.
The first tool 10A can be removed from the feeder wire by rotating the operating rod 34 to widen the gap between the upper roller 14 and the lower rollers 18A, 18B and releasing the clamped feeder wire, and the first tool 10B can be removed from the feeder wire by loosening the rope 117, which causes the guide hand 113 to move diagonally downward under its own weight, widening the gap between the hooks F1, F2 and releasing the wire.

The invention made by the inventor has been specifically described above based on an embodiment, but the present invention is not limited to the above embodiment. For example, in the first tool 10A, the upper roller 14 and the lower rollers 18A, 18B are described as being rotatably attached to the main frame 12 and the holding frame 16, respectively, but it is also possible to attach a member with a smooth curved surface such as a cylinder or cylinder with low surface friction resistance in a non-rotatable state.

In addition, in the above embodiment, a horizontally oriented J-shaped member is used as the wire accommodating plate 27A, 27B of the second tool 20, but it is also possible to use a horizontally oriented elongated U-shaped member whose lower side has the same length as the upper side.
In addition, the power feeder wire bundling tool installation tool and bundling method of the present invention are not limited to power feeders, but can be widely used when bundling electric wires that are laid in pairs at high altitudes by attaching bundling tools to them.
