Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is applicable to overhead distribution lines, etc.
The present invention relates to an indirect hot-line tool suspending device in hot-line work using a heavy indirect hot-line tool such as a hydraulic tool.

[0002]

2. Description of the Related Art FIG. 4 is a schematic explanatory view of a hot working operation using a conventional indirect hot working tool. As shown in the drawing, the other end of a support column 27 provided with a tool receiving table 25 at one end is attached to a side edge 21a of a bucket wheel 21 by a fixture 26.
Attach to Then, the worker 22 on the bucket car 21
However, the operation rod 23 having one end attached with the indirect hot-line tool 24 is deposited in the tool cradle 25, and the other end of the operation rod 23 is held in the indirect hot-line tool.
24 were operating.

[0003] In the above-described conventional working method, the weight of the indirect hot-line tool added to the worker is reduced by depositing the operating rod on the tool receiving pedestal. The weight burden added to the work increased, and the worker was tired. Also, depending on the tool holder,
Since the upper, lower, left and right working ranges of the tool are restricted, it has been necessary to remove the fixing of the cradle to the bucket truck each time the working range is changed.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and provides an indirect hot-line tool suspension apparatus which has a wide working range and improved operability while reducing operator fatigue. The features are: an insulating pillar formed so as to be adjustable in height, a spring balancer attached below the pillar, an arm protruding horizontally at the top of the pillar, and one end attached to the spring balancer at the top of the pillar. Insulated rope with the other end attached to the tip of the arm via a guide roller, and a hook fitting for supporting an indirect hot-line tool suspended via a moving pulley on the insulating rope between the guide roller and the attachment part at the tip of the arm. It is in that.

[0005]

FIG. 1 is a front view of a specific example of an indirect hot-line tool hanging tool according to the present invention, and FIG. 2 is a view taken along line XX of FIG. In the drawing, reference numeral 1 denotes a commercially available spring balancer having a built-in spring 1a therein, and an insulating rope 2 described later.
Is attached at one end. Reference numeral 3 denotes a hollow support body formed of an insulating material such as FRP, which has a screw rod 8 therein, and a slide support 4 at the tip end of the screw rod 8 which can move up and down in the support body 3. Is provided. And
By rotating the column elevating operation handle 7 attached to the column elevating drive gear box 6, one set of gears 6a and 6b in the gear box 6 is rotated, and the screw rod 8 engaged with this is moved up and down. Move in the direction. Accordingly, the slide column 4 moves in the column body 3 in the vertical direction, and the height of the column can be adjusted.

A rotary shaft 18 is provided at the upper end of the slide column 4, and has a horizontally protruding arm 9 attached by a guide roller 5 and a fixing pin 9a. Therefore, the arm 9 is rotatable in the horizontal direction about the rotation shaft 18, and when not needed, the fixing pin 9a is loosened so that the arm 9 can be folded down so as to be able to be folded downward about the pin 9b. is there.

The above-mentioned insulating rope 2 has one end attached to the spring balancer 1, and the other end passing through a guide roller 5 provided at the upper end of the slide support 4, and passing through the distal end 12
Mounted on A moving pulley 10 is provided between the insulating rope 2 between the guide roller 5 and the mounting portion 12 at the tip, and a hook fitting 11 for supporting an indirect hot-line tool is hung on the moving pulley 10. ing.

A protruding support arm 14 extends on a side surface of the column lifting drive gear box 6, and is provided with a mounting bracket 13 for mounting the device of the present invention on a side edge 21a of the bucket car. The device can be mounted on the bucket truck by fitting the mounting bracket 13 to the fixture 26 provided on the side edge 21a of the bucket truck and inserting the fixing pin 20. A base 17 is provided at the lower end of the column body 3, and the base 17 is positioned on the bottom surface of the bucket wheel, and the level of the entire apparatus is adjusted by a level adjustment handle 16. Reference numeral 19 denotes a lock handle for adjusting the height of the column and locking the column.

[0009]

[Action] Prior to hot-line work using indirect hot-line tools,
First, the device of the present invention is placed on a bucket truck, and the device mounting bracket 13 is used.
Is fitted to a fixture 26 attached to the side edge 21a of the bucket wheel, and the level variation of the bucket wheel is adjusted by the level adjustment handle 16 to position the apparatus. Next, the indirect hot-line tool is hung on the hook fitting 11, and the spring balancer 1 is adjusted to make the load zero. Then, the column is adjusted to a predetermined height by rotating the column up / down operation handle to perform the operation.

[0010]

According to the indirect hot-line tool suspension device of the present invention, by providing the spring balancer, the tool becomes zero-gravity at any position, improving the operability of the tool and reducing the fatigue of the operator. It can be significantly reduced. Also, as shown in Fig. 3, by using a moving pulley system as the tool suspension part, the load on the spring balancer is reduced to half of the tool weight, so that the capacity of the spring balancer can be reduced and the size can be reduced. Can be realized. Furthermore, since the tool is suspended by a rope, the working range is widened and workability is improved. Therefore,
It is extremely effective when used for live-line work such as overhead distribution lines using heavy indirect live-line tools.
