Abstract

PROBLEM TO BE SOLVED: To provide a method and an apparatus for installing spacers, wherein unstable and unsafe installation work by human power is obviated; spacers are properly installed on electric wires; and post-correcting work made unnecessary. SOLUTION: An spacer-installing apparatus is suspended from electric wires in such a manner that the installing apparatus can travel. All spacers 6 to be placed in one span are temporarily held on the spacer installing apparatus, in such a manner that none of them is in contact with the electric wires 1. The spacer-installing apparatus is them moved until it reaches a target position. Then the spacers 6 are released from the temporary holding state and secured on the electric wires 1. The main part 8 of the spacer installing apparatus has a driving mechanism, a mechanism (trigger) 12 to hold spacers 6 in temporary installation state, so that the spacers will not be in contact with electric wires, and a mechanism (trigger release) 13 to release spacers from temporary installation state and secure them on electric wires 1. The spacer-installing apparatus is also provided with a shaping roller that rotates on electric wires, to keep the spacers in the installation position at right angle.

2. Description of the Related Art In a conventional spacer mounting method, several workers traveled to a target mounting position together with a spacer loaded on a spacecraft and manually mounted the spacer. As shown in FIG. 5, the spacecraft is suspended on the electric wire 1 by the electric wire 1 by the wheel 2 arranged so as to match the conductor interval. The wheel 2 also plays a role in shaping to secure the conductor interval to the design value and facilitate the spacer mounting.

In the above-mentioned prior art, when mounting a large bundle multi-conductor spacer,
The position of the wires is about 1.5m above and below, and 1.8m from the step of the floating vehicle on which the worker is boarding, and requires a ladder-like step to attach the spacer to the wires above. Also, when attaching to the lower electric wire, there is an electric wire at the foot, so it is attached at the middle waist. For this reason, the worker requires a lot of labor to attach the spacer, and the work itself is directly affected by the weather in an unstable scaffold in the air, and it can be said that the work is difficult to secure safety. .

Further, the spacer is mounted behind the spacecraft so as not to hinder the traveling of the spacecraft, and it is required that the spacer be mounted so as to be gripped at a right angle to the electric wire.
However, due to the weight of the spacecraft, the shape of the electric wire that is laid between the towers bends at the position of the spacecraft. This inflection point is concentrated at the wheel position receiving the spacecraft. In order to mount the spacer at a position off this wheel, the mounted vehicle moves even if it is mounted at a right angle in the mounted state, and the bending point changes, so that the upper, middle, and lower wire positions of the mounted spacer are changed. Change and no longer be perpendicular to the wire. For this reason, the worker walks on the electric wire by himself without using the spacecraft again, at the stage where the spacer installation within the span where the influence of the weight of the spacecraft is eliminated has been completed, and the displaced spacer Must be corrected.

The provision of the above method is based on the following findings of the inventors. That is, the spacer uses a so-called boltless clamp structure in which the wire gripping portion is always tightened by the spring force, but by pulling the spring portion of the wire gripping portion in the opposite direction, the wire gripping portion directly contacts the wire. There is a function that does not perform this function, and the function has the same function for each gripped portion having several conductors in one spacer. With this function, the spacer can move on the electric wire. I found it. Therefore, the inventors have set such a function as a temporary mounting state, and then use a unique spacer mounting apparatus that can load spacers that are arranged in one spot at a time, and temporarily attach the spacer to this apparatus. The intended spacers were sequentially released from the temporarily attached holding state while the attached spacers were kept running and run along the electric wires.

It is preferable that the spacer mounting body includes a shaping roller that rolls on the electric wire to maintain the mounting state of the spacer at a right angle. This shaping roller is preferably provided before and after the spacer mounting device main body. With this configuration, even if the wire bending point occurs due to the weight of the spacer mounting device, the conductors of the wire are balanced by the front and rear shaping rollers in the spacer mounting portion in the spacer mounting device, and no displacement occurs after the device is moved. It is preferable that the diameter of the shaping roller be at least large enough to allow the shaping roller behind the shaping roller to ride over the spacer. No such shaping rollers have been found in conventional spacecraft. This is presumed to be that the aircraft did not want to be enlarged and that it was difficult to get over the spacer. It is desirable that the roller part is a cantilever wheel shape when crossing the spacer as described above.During running, the hook part moves and passes through the spacer only at the moment when the roller crosses the attached spacer without derailing from the electric wire. It is good to be able to do it. Such a crossover structure itself is a predetermined technique, and examples thereof include a cantilever wheel, a hanger wheel for a multi-conductor spacer (a product developed by our company), and a windmill type hanger wheel of another company.
