Description

[Detailed description of the invention] (1) Industrial application field This invention relates to a protective pipe insertion machine that automates the work of installing protective pipes (so-called polyethylene pipes) on distribution lines.
This particularly improves workability.

(2) Prior Art A protection tube insertion machine that automates the work of attaching a protection tube to a power distribution line is conventionally known, as disclosed in, for example, Japanese Utility Model Publication No. 53-45278.

(3) Problems that the invention aims to solve However, conventional protective tube insertion machines are used by hanging from power distribution lines, and the protective tube insertion part that inserts the protective tube into the electric wire is fixed, so it is difficult to When the tube insertion machine could not be positioned directly under the wire, there was a problem that the work could not be done or the protective tube could not be inserted smoothly into the wire.

(4) Means for solving the problems In order to solve the above problems, the present invention provides a protection pipe delivery unit that sends out the protection pipe, and a protection pipe that is attached to an electric wire and sent out by the protection pipe delivery unit. A protective tube insertion machine is equipped with a protective tube insertion section that is pushed open and inserted into an electric wire, and the protective tube delivery section and the protective tube insertion section are connected by a guide that guides the protective tube.
The protection tube insertion part is made swingable within a plane perpendicular to the axis of the electric wire into which the protection tube is inserted.

(5) Effect Due to the above configuration, it is not possible to position the protective tube insertion machine directly below the electric wire, and when the guide and the protective tube insertion part approach the electric wire from diagonally below, the protective tube insertion part must be aligned with the axis of the electric wire. The electric wire, the guide, and the protective tube insertion machine are positioned in the same plane by swinging in a plane perpendicular to , and the protective tube insertion work is performed.

(6) Examples Examples of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, the protective tube insertion machine of the present invention utilizes the sub-boom 4 of the lifting device 3 provided on the work platform 2 of the aerial work vehicle 1, and feeds the protective tube to the tip of the sub-boom 4. A delivery section 5 is attached, and a protection tube insertion section 6 for pushing open the protection tube sent out by the protection tube delivery section 5 and inserting it into the electric wire 8 is attached to the electric wire 8. A flexible guide 7 guides the protective tube between the
are connected by.

As shown in FIGS. 1 and 3, the protective tube delivery section 5 is provided with two pairs of opposing rollers 10 and a rod 11 driven by a hydraulic motor 9. The legs of the tube 16 are held between rollers 10 and the protection tube 16 is sent out by the rotation of the rollers 10, and the protection tube insertion part 6 has a locking tool 13 operated by a handle 14.
It is removably attached to the electric wire 8 with It is movably mounted. The guide 7 has a protective tube 16 sliding along its outer periphery, and can be bent elastically in any direction, up, down, left, or right.

With the above configuration, when installing the protection pipe to the power distribution line, first remove the head of the sub-boom 4 of the lifting device 3 provided in the aerial work vehicle, and then feed the protection pipe to the tip of the sub-boom 4. Part 5
, position the protective tube delivery section 5 below the electric wire 8 , and then attach the protective tube insertion section 6 with the locking tool 13 .
Attach to the wire. At this time, since the guide 7 has flexibility, there is a large degree of freedom in the positional relationship between the protective tube delivery section 5 and the electric wire 8, so that the protective tube insertion section 6 can be easily attached to the electric wire 8.

In the above state, the motor 9 of the protective tube delivery section 5 is driven to rotate the roller 10, and the protection tube 16 is inserted into the rod 11 from the rear of the protection tube delivery section 5. The protection tube 16 is sent out along the outer periphery of the rod 11 and the guide 7 by the rotation of the roller 10, and the protection tube 16 is pushed open left and right by the collars 15 fixed to both sides of the protection tube insertion part 6, and is ejected from this opening. It is attached to the outer circumference of the electric wire. By attaching the next protection tube to the rear end of the protection tube, the protection tubes can be successively attached to the electric wire 8.

If the protective tube insertion machine cannot be positioned directly below the wire, the protective tube insertion section must be attached to the wire from a diagonally downward position, so if the protective tube insertion section is fixed to the guide, Figure 5a
As shown in the figure, since the guide 7, the protective tube insertion part 6, and the electric wire 8' are not on the same plane, it is difficult to attach the protective tube insertion part 6 to the electric wire 8', and it is difficult to attach the protective tube insertion part 6 to the electric wire 8'. Even if it is possible to insert the protective tube into the electric wire 8', the protective tube cannot be inserted smoothly into the electric wire 8', but as shown in FIG. By locating the protection tube insertion part 6 and the electric wire 8' in the same plane, the protection tube insertion part 6 can be easily attached to the electric wire 8', and the protection tube can also be smoothly inserted into the electric wire 8'. be exposed.

(7) Effects of the invention As described above, according to the invention, it is possible to insert the protective tube into the electric wire without placing the protective tube insertion machine directly under the electric wire. This has the effect of expanding the scope of use.
