Description

[Detailed Description of the Invention] Production LhΔ5'' ■ and 1 This invention is a method for binding wires around high-voltage distribution lines and tightening them (high-voltage live wire work). This invention relates to a binding tool used by being attached to a tip drive device for a work manipulator.

Traditionally, binding work, which is high-voltage live wire work on high-voltage overhead distribution lines, has been carried out at high places by workers wearing insulating protective gear and using manual binding tools for high-voltage live wire work. They got into their cars and worked on the live wires by hand. However, this method requires the operator to hold a hand-operated binding tool in his/her hand, which poses a risk of electric shock and physical fatigue for the worker.

Therefore, there has been a demand for a device that can mechanically and automatically perform such high-voltage live line work.

In order to satisfy this demand, an electrically insulating live wire work manipulator and a binding tool that is attached to the tip of this manipulator and performs binding work have been devised.

However, there are two actions required for this kind of binding work: wrapping the binding wire around the wire, and twisting and tightening both ends of the binding wire. This requires two actions. However, none of the previously proposed devices can perform such operations, and those that can perform only one operation cannot be operated or handled without preparing two live-line work manipulators. Therefore, if a large number of live-line work manipulators are installed in the limited space of the bucket at the tip of the boom of an aerial work vehicle, this will lead to deterioration of the workability of the workers and an increase in the weight of the boom tip. The work of attaching and detaching the binding tool for live wire work to the tip drive device was also troublesome.

This invention was made by paying attention to such conventional problems, and is driven by a tip drive device provided at the tip of a live wire work manipulator to bind wires around electric wires. A binding tool for tightening by hooking includes a roughly cylindrical rotating drum in which an annular binding wire is set on the inner circumferential surface, the wire is inserted through the wire insertion opening, and the binding wire is hung around the wire by rotational action. a first drive shaft that rotates the rotary drum in response to an input from the tip drive device; a hook member that twists and tightens both ends of the bind wire that is hung around the electric wire by rotation; and the tip The present invention is characterized in that it is a binding tool for a live wire work manipulator, which has a second drive shaft that rotates the hook member by input from a drive device.

According to this method, an annular binding wire is set on the inner surface of the binding tool with one end hooked onto the hook member. Next, the live wire work manipulator is operated to insert the wire into the cylindrical rotating drum through the wire insertion opening. Then, by driving the tip drive device provided at the tip of the live wire work manipulator, the rotary drum of the binding tool is rotated via the first drive shaft, and the binding wire is hung around the electric wire. Hook the other end onto the hook. Thereafter, the hook parts on which both ends of the bind wire are hung are rotated via the second drive shaft to twist and tighten both ends of the bind wire. Thereafter, the hook portion is removed from the binding wire to complete the wire binding operation.

In this way, you can bind wires with this one binding tool, so there is no need to prepare two or more live wire work manipulators like in the past, and the tip of the boom of an aerial work vehicle can be This will reduce the weight of the bucket and improve the efficiency of live wire work.

On the other hand, FIG. 8 shows a binding wire length adjustment jig 26. This jig 26 has a helical rod 28 disposed on a rectangular frame-shaped base 27, and when this rod 28 is rotated by a handle 29, a movable plate 30 is moved in the axial direction of the helical rod 28. It looks like this. Furthermore, a pair of pins 31.32 are protruded from the base 27, and both pins 31.3
2 and the moving plate 30, as shown in the figure, bind line A
is hung, and with this bind wire A stretched, the terminal portion A1 is entwined to form a ring-shaped bind wire A.

In this case, by moving the movable plate 30 to a predetermined position, the bind wire A can be formed with a predetermined length depending on the thickness of the electric wire B to be bound.

Next, a method of using the binding tool for a live line work manipulator having such a configuration will be explained.

In advance, the first end drive device 5 of the binding tool 6 is attached to the end drive device 5 attached to the end portion 4a of the live wire work manipulator 4.
It is attached via the second drive connection 11.19 and the connection fixation 25.

On the other hand, a ring-shaped bind wire A having a length suitable for the thickness of the electric wire B is formed using a bind wire length adjustment jig 26 shown in FIG.

Then, perform the binding operation as follows. First, the worker connects the binding line A formed as described above to
As shown in the third time and FIG. 4, the rotary drum 8 is hooked on the bind holding portion 8C on the inner peripheral wall, and one end portion A2 is hooked on the hook portion 9b of the hook member 9.

Next, by operating the live wire work manipulator 4 and moving the binding tool 6, the electric wire B is inserted into the rotating drum 8 through the wire insertion opening 8a, as shown in FIG.

When the electric wire B is inserted into a predetermined position, a signal from the set detection optical sensor 42 is input to the electric control circuit 40 via the optical fiber 44. A control signal corresponding to the binding operation from the electric control circuit 40 is input to the hydraulic control circuit 41 via the cable 45. Then, hydraulic oil is sent from this hydraulic control circuit 41 to the hydraulic motor 5b of the tip drive device 5 via the hydraulic hose 46.

Now, the first drive shaft 1 is connected to the connecting shaft 5a of the tip drive device 5.
0 is driven, the spur gears 12, 13, worms 14, . Rotating drum 8 via worm wheel 15 etc.
is rotated in the direction of the arrow in FIG. 3 (counterclockwise).

As the rotating drum 8 rotates, the tip A of the bind fiA reaches near the point X in FIG.
The force of the electric wire B causes the binding wire A to separate from the binding holding portion 8c of the rotating drum 8. Then, the tip end A3 of this binding line A will be caught on the hook portion 9b.

Thereafter, the second drive shaft 18 is driven by the tip drive device 5, so that the small spur gear 20. The hook member 9 rotates around the shaft portion 9a via the large spur gear 21 and bevel gears 22 and 23. This rotation causes both ends A of the binding line A to
2. A, are twisted and connected to each other. Due to this rotation, the hook member 9 moves forward somewhat against the biasing force of the spring 17 as the shaft portion 9a slides within the cylinder body 16. In this case, when the light from the end detection optical sensor 42 passes through the detection notch 24a of the rotating disk 24, this signal is input to the electric control circuit 40 via the optical fiber 44, and the hook member 9 When the number of rotations of the hook member 9 is detected and the rotation speed of the hook member 9 has been rotated a predetermined number of times, a control signal from the electric control circuit 40 causes the hook member 9 to
The rotation will be automatically stopped. Incidentally, the rotation area of the hook member 9 is secured by the wire insertion opening 8a of the rotating drum 8 having a predetermined width.

Thereafter, the rotary drum 8 is rotated in the opposite direction to the above-mentioned direction by a control signal from the electric control circuit 40 and returned to its original position, and then the live wire work manipulator 4 is operated to lower the binding tool 6. With this, the hook member 9 is removed from the binding line A, and the binding operation is completed.

In this way, one binding tool 6 is used to rotate the binding wire A around the electric wire B.

Terminal part A2 of this binding line A. Since it is possible to perform the work of twisting and connecting A, the binding work can be completed with only this one tool 6. Therefore, predetermined live wire work can be performed with one manipulator 4 without the need to prepare two or more manipulators as in the conventional case. Therefore, the weight increase at the tip of the boom can be reduced compared to the conventional technology, and the work space for the operator can be expanded.

Moreover, each optical sensor 42, 43 . electrical control circuit 40,
By providing the hydraulic control circuit 41 and the like, the binding work can be automated and the -layer workability can be improved.

As explained above, by using the binding tool of the present invention, multiple operations can be performed with this tool, and binding work can be performed with fewer live wire work manipulators than before. This reduces the weight on the tip of the boom of an aerial work vehicle, expands the work space for the worker, and makes it easy to attach and detach tools for live-line work. This has the practical effect of improving work efficiency.
