Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a hole-drilling pole-erecting vehicle configured such that the auger device can be removed when not working.

[Background of the idea]

Almost all work leading up to the erection of utility poles, etc. to support power transmission lines or telephone lines, etc.
In other words, all work from digging holes to erecting pillars was done manually. For this reason, the work takes a long time and requires a large number of workers, resulting in enormous costs and, furthermore, the work itself is extremely difficult. From this point of view, the development of mechanization of pole erection work is progressing at a rapid pace, and some results have been obtained. For example, after digging a hole with an auger device installed on a boom, the auger device is placed horizontally on the lower side of the boom, and then a column is lifted up using a hook. A pole erecting vehicle is proposed. However, this hole-drilling pole-erecting vehicle has a problem in that running stability during movement is poor.
That is, as shown in FIG. 3, the auger device 21 is placed next to the side of the boom 22 when the excavating and pole-erecting vehicle is moving. Since the center of gravity is high, the center of gravity becomes even higher, resulting in poor running stability. Furthermore, when the hole-drilling and pole-erecting vehicle is traveling, the auger device 21 occupies a position that almost blocks the window at the rear of the driver's seat, obstructing the rear view and impairing drivability. In addition, as shown in Figure 4, during pillar erection work,
The auger device 21 is installed horizontally on the side of the boom 22, which makes it difficult to lift the column.
There is also the problem that the workability of the pillar erection work itself is not that good.

DISCLOSURE OF THE INVENTION The first object of the present invention is to provide a hole-drilling pole-erecting vehicle that has excellent running performance when traveling. A second object of the present invention is to provide a hole-digging pole-erecting vehicle that is excellent in pole-erecting workability. The above purpose is to provide a straight-extendable boom whose base is attached to a turntable, which can be raised and extended, a bendable boom installed at the end of this straight-extendable boom, and an auger device and a utility pole installed at the end of this bendable boom. and an auger device configured to be able to be gripped by the gripping device, the auger device is gripped by the gripping device during hole digging work, and the auger device is gripped by the gripping device during pole erection work. The pole is removed from a gripping device, and the pillar is gripped by the gripping device.

【Example】

Figures 1 and 2 show one embodiment of the pit-drilling pole-erecting vehicle according to the present invention, and Figure 1 is an overall schematic diagram;
Figure 2 is an explanatory diagram of the hole digging and pillar erection process. In each figure, A is a hole-drilling pole-erecting vehicle, 1 is a turntable, 2 is a straight-extend boom (in this example, a two-stage telescopic boom is adopted), and 3 is the second-stage straight-extend boom 2a of the straight-extend boom 2. A bending/extending boom is provided at the tip so that it can bend and extend (the bending/extending boom 3 is configured to bend and extend along the lower surface of the straight boom 2), 4 is an undulating cylinder, and 5 is a bending/extending cylinder. Reference numeral 6 denotes a gripping device that is swingably provided at the tip of the bendable boom 3 and can selectively grip the auger device 7 and the utility pole P. Therefore, it is configured to be controlled (the swing angle of the gripping device 6 is adjusted to a predetermined angle under control by the operating device, and the gripping of the telephone pole P is also controlled, for example). 7 is an auger device, and this auger device 7 is composed of an auger motor 7a, a drill portion 7b, and, if necessary, a joint member (not shown) between the auger motor 7a and the drill portion 7b. constitutes a portion that can be firmly gripped by the gripping device 6. Next, the digging and pole-erecting work performed by the hole-digging and pole-erecting vehicle A constructed as described above will be explained with reference to FIG. First, as shown in FIG. 2a, the auger device 7 is held by the gripping device 6, and the drill portion 7b of the auger device 7 is used to drill a predetermined hole using the operating device installed on the turntable 1. Control in position. Then, as shown in FIG. 2b, the user operates the operating device to start digging a hole, and the hole 8 is dug. When the hole digging work is completed, the operation device is operated to transport the auger device 7 to a predetermined position (the set position of the auger device 7) on the hole digging and pole erection vehicle A, and then the gripping device 6 is moved.
The grip of the auger device 7 is released. After the grasping of the auger device 7 by the grasping device 6 is released, the operation device is subsequently operated to remove the utility pole P placed on the digging pole construction vehicle A or at a predetermined position.
is gripped by the gripping device 6, and the operating device is further operated to convey the utility pole P to the position of the hole 8 as shown in FIG. 2c. Thereafter, as shown in FIG. 2d, the utility pole P is inserted into the hole 8 by operating the operating device, and soil, asphalt, or concrete is poured in to stabilize the utility pole P. The pole erection work is completed by removing the pole from the utility pole P. In the above-mentioned series of work steps, in the work steps for erecting the utility pole P represented by c and d in FIG. Therefore, the auger device 7 does not get in the way at all when the utility pole P is grasped by the grasping device 6 and transported to a predetermined position, making the work of erecting the utility pole P more efficient. I can do it well. Also, during the erection work of the utility pole P, the auger device is not placed next to the straight-extending boom, so for example, soil attached to the drill part of the auger device attached to the side may accidentally fall from above. The operator will not experience any unpleasant experience. Furthermore, when the pole-erecting work is completed and the digging and pole-erecting vehicle A is to be moved, the auger device 7 can be stored in a predetermined position separately from the boom. The auger device 7
Since it can be stored by placing it at the bottom, the center of gravity is not as high as in the case shown in FIG. 3, and therefore the excavator and pole erecting vehicle can move with great stability. Furthermore, as shown in Fig. 3, the auger device 7 does not block the rear window of the driver's seat of the digging and pole-erecting truck A, and the rear view is only obstructed. Because there are fewer, the drivability is also better.

【effect】

The digging pole erection vehicle according to the present invention includes a straight-extending boom that can raise and lower and expand and contract, the base of which is provided on a turntable, a bending boom installed at the end of the straight-extending boom, and a bending boom installed at the end of the bending boom. a gripping device that is provided and can selectively grip the auger device and the utility pole;
and an auger device configured to be grippable by the gripping device, the auger device is gripped by the gripping device during hole digging work, and the auger device is removed from the gripping device during pole erection work, and the auger device is gripped by the gripping device. Since it was configured to be carried out by holding the pillar,
For example, in the process of erecting a utility pole, the auger device can be removed when the utility pole is not being dug, and the auger device does not get in the way when the utility pole is being gripped by the gripping device or transported to a predetermined position. Erection work can be done efficiently, and since the auger device is not placed sideways on the boom during the erection work of utility poles, for example, dirt attached to the drill part of the auger device installed sideways can be easily removed from above. It will not fall down suddenly, the operator will not face unpleasant situations, and the work environment will be improved.
When the pole-erecting work is completed and the pole-erecting vehicle is to be moved, the auger device can be removed and stored in the designated position, so the center of gravity is not too high, and therefore the pole-erecting vehicle can be moved easily. It has features such as high safety in running and moving.
