Protection pipe indirect live wire installation device {INSULATION PROTECTOR INSTALLING DEVICE FOR INDIRECT LIVE WIRE WORK}

The present invention relates to an apparatus for installing an indirect live wire for a protective tube, and more particularly, to an apparatus for installing an indirect live wire for a protective tube capable of installing a protective tube on an electric wire.

In general, live line work refers to line work performed while power transmission continues without a power outage on the line. In this case, direct live work is performed only in limited cases where it is difficult to cut off power, such as in transmission and distribution facilities, because the risk of safety accidents is very high.

On the other hand, in general, since high-voltage wires for supplying power to buildings are arranged close to various workpieces, electric shock disasters frequently occur due to proximity or contact with high-voltage wires when working close to the power lines. In addition, there are often cases in which a power outage accident is caused due to a foreign object contact with an electrical work piece caused by rain, wind, and current.

In order to prevent such electric shock disasters and blackout accidents, straight-line insulated protective tubes are manufactured to protect the straight parts of high-voltage wires at construction sites, etc. to ensure the safety of workers when working near power lines.

To this end, when the hydraulic motor 315 of the driving unit 300 is driven, the rotational power is transmitted to the power transmission unit 320 by the meshing force of the worm 317 and the worm wheel 327 , and the power is transmitted The rotational force of the part 320 is again transmitted to the drive shaft 221 and transmitted to the drive gear 220 .

Accordingly, when the driving gear 220 rotates, the interlocking gear 232 of the first feeding roller units 230 and 230 ′ meshed with the driving gear 220 is operated in interlocking operation, and the first feeding roller unit (230) and (230') are rotated.

That is, when the rotational force is transmitted to the first feeding roller units 230 and 230 ′ as described above with reference to FIG. 11 , the first feeding roller units 230 and 230 ′ are installed in the mounting bracket 240 . A predetermined elasticity is applied by the operation of the spring 241 to press the cover portion 21 of the protective tube 20 , while frictional rolling acts to pull the protective tube 20 backward and move it.

At this time, in the present invention, the second feeding roller parts 422 and 422 ′ and the feeding bearings 431 and 431 ′ are configured on the guide plate 420 and the guide rod 430 , respectively. 20) will guide the smooth movement of

Accordingly, when the front end of the protective tube 20 moved as described above is positioned at the rear end of the guide rod 430 , it comes into contact with the electric wire 10 gripped and fixed by the electric wire fixing unit 450 .

At this time, the fixed electric wire 10 is configured to form an inclination with the guide portion 400, the protective tube 20 enters and the wire ( 10) is accommodated in the cover part 21, and the electric wire 10 is completely attached without separation by the elastic restoring force of the flange part 22 of the protective tube 20.

That is, in the process of moving backward by the operation of the feeding part 200 , the protective pipe 20 automatically continuously attaches the electric wire 10 without a separate flange part 22 opening operation.

According to the above contents, the protection pipe indirect live wire installation device according to the present invention automatically installs the protection pipe on the electric wire by the operation of the feeding part, so that the operator does not need to be close to the electric wire and secures a safe separation distance from the electric wire. work can be done.

In addition, the present invention protection pipe indirect live wire installation device can be installed while securing a safe distance from the wire even when the protective pipe enters the feeding part by the guide pipe, so all work of the wire protection measure is indirect live wire work. can be performed with

In addition, the indirect live wire installation device for the protection pipe according to the present invention operates the worm shaft protruding outside of the driving unit housing with a separate rotating tool when the hydraulic motor fails or hydraulic pressure cannot be provided in the process of driving the driving unit. Manual operation is possible, so it is possible to cope with various situations.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible by those skilled in the art to which the art pertains. will understand
