Description

Insulator For An Over Head Line Of Electric Pole

[0001] The present invention relates to a low voltage line connecting suspension for a pole.

Generally, the electric pole is installed from the top by the wire or rack in the order of the processing branch line, the special power line, the neutral line, and the communication line. The special power line is horizontally arranged through the wire, and the working wire, communication line, As shown in FIG.

However, when it is desired to newly install a working wire in such a conventional electric wire, it is difficult to attach a strap provided with a hanging insulator to the rack in a live wire state. Therefore, an additional rack is provided at the lower end of the rack, The machined wire was extended through the suspension insulator.

However, in the case of extension work as described above, there is a phenomenon that the distance between the ground and the working wire is shortened and the wire connection is from the upper end to the lower end, so that twist of the wire and work are very troublesome. Therefore, there is a problem that the danger of electric wire accident and safety accident is exposed as it is, and in particular, there is a problem that a working wire, a communication line, and a low voltage wire for maintaining the ground level during the crossing of the road have to be reworked.

Meanwhile, it is desirable that the distance between the telephone pole and the neighboring building is separated by a predetermined distance or more. In recent years, due to the remodeling or reconstruction of the building, the building may be located in the telephone pole and the telephone pole may be disposed adjacent to the telephone pole.

In the case where a new working wire is to be connected in a state in which a telephone pole and a building are arranged so as to be adjacent to each other, it is very inconvenient because the conventional rack and working wire must be rotated around the telephone pole, In the case of electric wires, there is a problem that electrical users are protested because it is a risk factor of an electric accident for a worker and the electric connection should be disconnected for a predetermined time.

As mentioned above, the machined wire is not easy to move from the live wire state, and therefore, only the band is rotated so as to set the machining wire in the installation direction. However, since the worker must directly work up the work wire, the construction time is considerably long .

Therefore, in the case of extending the new working wire in the adjacent arrangement of the telephone pole and the building, research on the suspension wire which can expand the working wire easily and easily while maintaining the installation state of the conventional rack and the working distribution line was actively conducted.

The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a low-voltage wire connecting and suspending insulator capable of easily and easily expanding a working wire while maintaining the installation state of a conventional rack and a working distribution line, The purpose is to provide.

According to an aspect of the present invention,

A rail-type band having a rail portion arranged to face each other on the circumferential surface, the rail-type band being fixed to the circumferential surface of the pole;

And a plurality of roller members rotatably installed at one side of the upper and lower sides of the bracket body, the fixing bracket being mounted on the rail to move along the rail portion;

A driving motor installed in the fixing bracket for forcibly rotating any one of the plurality of roller members;

A guide member formed along a circumferential surface of the rack body, a stopper formed at a distal end of the rack body, and a mounting hole vertically penetrating the guide member. A rack provided,

A suspending insulator disposed inside the rack,

An adjusting member rotatably fixed through the mounting hole and the suspending insulator of the rack vertically so as to have a cut surface formed so as to be opposed to the upper and lower parts,

A half portion and a slit portion which are cut along the longitudinal direction and are repeatedly formed in a line on the incised inner surface so as to be slidably inserted into the guide portion of the rack, A pair of length adjusting pieces which are restricted in movement in the arrangement and can be moved in the longitudinal direction,

A hanging insulator fixing device provided on the outer surface of the pair of length adjusting pieces so as to be rotatable via a fastening member and having an angle adjusting piece for adjusting the angle of the extended hanging insulator provided at the other end via a fixing member;

And a switch unit installed on the electric pole and controlling operation of the drive motor so as to be rotated in the forward and reverse directions.

According to the present invention as described above, the length adjusting piece provided with the angle adjusting piece is inserted into the rack, and even if the building is disposed adjacent to the hanging insulator fixing device, the angle adjusting piece can be easily avoided And it is possible to install a new working wire easily through the extended suspension insulator while maintaining the safety distance (proper distance) between the suspension fixture and the building.

In addition, when it is judged that the distance between the existing working wire and the new working wire is too close to each other, the adjusting wires and the length adjusting piece provided on the rack are used to separate the working wires from each other, The accident can be prevented and prevented in advance.

In addition, since the position of the suspending insulator fixing device can be automatically adjusted by using the driving motor and the switch portion, it is possible to conveniently adjust the position without removing the existing installed band and re-work, There is no need to protect the operator from electrical safety accidents such as electric shock.
