Further, on both sides of the outer frame (62) there are holes for attaching hooks, groove wheels, etc., 4 in total, 8 in total, and auxiliary tools such as lifting, towing, etc. can be attached as necessary.

Next, various types of work performed by the electrical installation work vehicle having the above configuration will be explained.

First, as shown in FIGS. 12 and 13, a hole for a pillar is excavated using an earth auger device. Such an earth auger device is composed of a drive device (80), an intermediate shaft (81), and an earth auger (82) attached to a moving base (32) of an electrical work vehicle according to the present invention.
Stop the vehicle frame (1) on the scheduled A device, stand the compound league (19) upright,

Ground. Lower the moving base (32) to the lower end, remove the earth auger drive device (80), and connect the hydraulic hose. Initiate the rotation and, if necessary, move the moving base (32
) lower. To remove soil, the movable base (32) is occasionally raised to remove the soil.

To facilitate excavation, the moving base (32) can be lowered by extending and contracting the moving hydraulic cylinder (42), and the maximum vertical force applied to the earth auger (82) is the weight of the vehicle body.

After such excavation work, the utility pole (A) must be transported to the excavation location. To do this, first load the utility pole (A) onto the electrical installation vehicle.

The procedure for loading the utility pole (A) shown in FIGS. 14 to 18 is shown. In addition, the telephone pole (A) is a concrete pole (A-
1) shows a case consisting of an intermediate steel pipe (A-2) and an upper steel pipe (A-3). In this case, first insert the insertion rod (70a) of the rotating shaft (70b') provided at the upper end of the side loading aid (70) into the upper front f & 4 III of the vehicle body frame 11).
The side-loading type pillar support installed at the location is detachably attached to the side wall of the section (16) as shown in FIG.

In addition, the details of the rotating shaft (70b) are shown in FIG. 15. Thereafter, the wire (72) from the winch (14) is wound around the intermediate steel pipe (A-2) on the ground, and by driving the winch (14), it is pulled up along the auxiliary fitting (70), and the wire (72) is pulled up along the utility pole receiver (16). ). The upper steel pipe (A-3) is similarly placed on the utility pole receiver (16) on the other side.

Next, in order to load the concrete pillar (A-1) onto the work vehicle, as shown in Figures 16 and 17, the composite league (19) is erected and the tip of the concrete pillar (A-1) is Lift the support bracket (73) onto the concrete (A

79) and gradually increase. Concrete pillar (A-1)
The weight of the composite league (19) is the lower end of the receiving roller (54).
When the support metal fitting (75) becomes free, remove the metal fitting. Furthermore, as shown in FIGS. 19 and 20, the utility pole (A) is gradually pulled up using the loading winch (14), the moving base (32) is moved to the right side in the figure, and the vehicle body frame +1+
or change the angle of the compound league (19) to the utility pole (
Alternately perform operations such as following the slope of A), and align the body frame (
Place the concrete pillar (A-1) on top of 11.

After loading the utility pole (A) in the manner described above, it is preferable to position the movable base (32) at the lower end of the utility pole (A) in front of the pole. In this case, adjustments will be made after arriving at the pole erection site. FIG. 21 is an explanatory diagram showing that the league leg (39) can be used for unloading a utility pole (A) from a trunk or for transporting a short distance in addition to the above-mentioned uses.

In this loaded transportation position, the material is transported to the location where the pillar is erected.

At the same location, the utility pole (
A) is lowered onto the ground, but since the concrete column (A-1) loaded in the center of the work vehicle is in the position in front of the column, there is no need to lower it when subsequently erecting the column.

Next is the pole construction, but first is the all-concrete utility pole (A).
I will talk about the erection of pillars. The utility pole (A) is transported to the pole erected location in the state shown by the imaginary line in Figure 22, and upon arrival, the outriggers (17) are stretched and grounded, and the stabilizing auxiliary legs (85) are attached to the front of the vehicle body frame (1). It is attached by inserting and connecting the insertion end (85a) provided at one end into the insertion hole provided in the vehicle body frame (1). Note that (85b) is a wheel attached to the rear end of the stabilizing auxiliary leg (85). When erecting the pole, first drive the loading winch (14) to move the utility pole (A) on the composite lead duct 19), align the lower end with the lower end of the league (19), and at that position attach the pole erecting wire rope (86). ) to connect the hanging bracket (75) and the moving base (32), and attach the winch (
Remove the wire lobe (76) from the movable base (3)
2) Hang the safety belt on the outside of the utility pole (A).

The composite league (19) is gradually raised, and when it stands upright, the utility pole (8) is lowered together with the moving base (32) and buried at a predetermined depth in the excavation pit (B). Hanging fittings (75)
shall be buried together with the utility pole (A).

In addition, the base concrete column (A-1), intermediate steel pipe (A-2)
) and an upper steel pipe (A-3), if there is sufficient space at the location where the pillar is erected, the base concrete pillar (8-1) and the intermediate steel pipe (A-2) are installed at the ground surface.
and the upper steel pipe (A-3) will be connected on the ground to form one piece. Thereafter, one piece is loaded into the center of the composite league (19), and the pillars are erected in the same manner as described above.

Furthermore, when erecting an urban composite pillar in a narrow place, it is done in the manner shown in Figs. 23 to 27.

The base concrete column (A-1) was erected according to the above procedure, and after temporary burial, the intermediate steel pipe (A-2) was installed with a composite leak (1
9) to stand upright and tie it to the base concrete pillar (A-1) as shown. Next, fix the auxiliary bracket for pole erection +-<92) on the movable base (32), set the auxiliary pole for pole erection (93), and raise the movable base (32) to the top end. Lift the upper steel pipe (A-3) from the supporting pillar (93) with the loading switch (95), fit it into the intermediate steel pipe (A-3),
> (A-3) is a single piece. Next is the moving base (32)
Lower it to the lowest level, turn the bolt into the hole for the scaffold above the middle 1l-17 (A-2), and position it slightly above. The auxiliary pillar (93) is connected with wire lobes so as to hang from the holes in the arms on both sides of the upper end, and a safety heald is loosely hung on the outside. Hold the lower part with both arms of the auxiliary pillar Brakeso I-(92),
Hang the safety bell 1-(96) on the outside. In this posture, the base concrete column (A-1) and the intermediate steel pipe (A-'2) are released, and the movable base (32) gradually rises to reach the upper end. Next, put the composite league (19) slightly behind (2-3
degree), that is, the lower end of the league is slightly raised, and the grounding cylinder of the outrigger (17) is slightly raised.
The lower end of the intermediate steel pipe (8-2) is the base concrete column (A-
1) Gently advance to a position where it can fit into the upper end and stop. Stand the composite leader (19) upright and attach the outrigger (1
7), lower the movable base (32), check the match mark, and connect. After joining, each heald and wire rope are uncoupled, the movable base (32) is lowered, the composite leader (19) is lowered onto the vehicle body frame (1,), and the auxiliary column (
93) and Brakeso 1-(92) are removed. In addition, when the upper and lower ends of the utility poles are aligned, and when fitting, one person must use a ladder or the like to visually check and slightly open the poles by hand.
