[0009]

Embodiments of the present invention will be described with reference to the accompanying drawings.

In the first embodiment of the present invention, as shown in FIGS. 1 and 2, above the working area of the sloped land 1 such as a slope (at a high place), the upper end can freely swing in various directions. Jib 2
There is standing.

In the case shown in the figure, the jib 2 is placed upright on the sloped ground 1 and, at the same time, the seat 3 is fixed via an anchor or the like, and the jib 2 is provided on the seat 3 so as to be pivotable by appropriate means. The lower end of the jib 2 is supported on a certain swivel seat 4 via the universal joint 5, but may be erected by a method other than the above.

As shown in the figure, the jib 2 can be divided into predetermined lengths (for example, so that it can be carried and handled manually), and can be assembled after being carried into a standing position.

Between the upper end of the jib 2 and the left and right above the standing point of the jib 2 on the inclined ground 1, two left and right side wires 7, 7 are wound up and wound up by operating the first winch 6. I have.

In the case of the drawing, the first side winches 6 are fixed to the sloping ground 1 by anchors and the like, and the two side wires 7, 7 are pulled out from the drum of the first winch 6 in the case of the drawing. , 7 are stopped at the upper end of the jib 2, but in a manner other than the above, the side wires 7, 7 are wound up by operating the first winch 6, and are rewound to swing the upper end of the jib 2 back and forth, left and right. Just move it.

Further, a center wire 10 is wound between the moving body 8 on the sloped land 1 and at least the upper end of the jib 2 by winding and rewinding by operating the second winch 9.

In the case shown in the figure, the center wire 10 fixes the second winch 9 to the sloped ground 1 via an anchor or the like, and pulls the center wire 10 pulled out of the drum of the second winch 9 into the groove at the upper end of the jib 2. 11, and the tip of the center wire 10 was connected to the moving body 8. The second winch 9 was installed on the moving body 8, and the pulled out center wire 10 was connected to the upper end of the jib 2 or passed over the sheave 11. , The center wire 1 to the moving body 8
In some cases, the tip of 0 may be connected (not shown). In short, the center wire 10 is wound up by operating the second winch 9, and the moving body 8 is moved up and down by rewinding.

Also, two left and right side wires 13, 13 that can be wound and rewound by operating the third winch 12 are attached to the two left and right points below the moving body 8 on the sloped land 1 and the moving body 8.
Is stretched out.

Although the left and right third winches 12 are installed on the sloped land 1 in the illustrated case, they may be mounted on the moving body 8. At this time, the ends of the side wires 13 may be fixed to the sloped land 1.

Of course, in order to move the moving body 8 from the sloping ground 1 by the tension of the center wire 10 and the side wires 13 of the third winch 12, the side wires 1
The part near the fixing point of the slopes 3 and 13 with respect to the slope 1 is the pulley 1
It is largely separated (floated) from the sloping ground 1 by the fixing column member 15 attached. The jib 15 swings and turns with the same configuration as the jib 2.

With the above configuration, the moving body 8 on the sloped ground 1 winds the center wire 10 by operating the second winch 9 and the left and right side wires 13 by operating the third winch 12, respectively. Then, the center wire 10 and the left and right side wires 13 are tensioned to float the moving body 8 on the sloped ground 1.

When the center wire 10 is wound by the second winch 9 while rewinding the left and right side wires 13 of the third winch 12 while maintaining the floating state, the moving body 8 in the floating state moves upward. .

When moving the moving body 8 downward, the third wire is moved while the center wire 10 of the second winch 9 is rewound.
The right and left side wires 13 may be wound by the winch 12.

Further, the right first winch 6 and the third winch 6 in FIG.
When the side wires 7, 13 on the left side of the first winch 6 in FIG. 1 and the other side wires 7, 13 on the other side of the third winch 12 in FIG. 8 moves.

When moving the moving body 8 to the right, FIG.
The first side winch 6 and the one side wire 7, 13 of the third winch 12 are unwound, respectively, and the other side wire 7, 13 on the right side of the first winch 6 and the third winch 12 in FIG. Good.

The operation method other than the above is the first operation method.
One of the two left and right side wires 7, 7 by the winch 6 may be wound up, and the other may be rewound to swing the jib 2 left or right.

The moving body 8 can be used in a method other than mounting a drilling machine A on the moving body 8 and drilling an anchor hole, or drilling with a drilling machine held by an operator on the moving body 8. Excavation work on the slope, assembling the screed by the worker on the sloping surface, placing mortar on the screed (concreting concrete, loading the screed, and loading and unloading materials when constructing steel towers etc. on the slope 1) Also).

In the second embodiment of the present invention, as shown in FIGS. 3 and 4, the movable body 8 is provided with wheels 21 which can swing freely in an appropriate arrangement. This wheel 21 is
Although arranged on both sides of the moving body 8, the number and the position may be determined as appropriate.

With the above construction, the wheels 21 are brought into contact with the sloping ground 1 so that the vertical and horizontal movements can be smoothly performed on the sloping ground 1.

The movement of the moving body 8 in the vertical and horizontal directions is the same as in the first embodiment, and will not be described.

In the third embodiment of the present invention, as shown in FIGS. 5 and 6, the movable body 8 is provided with a swingable sled 31 in an appropriate arrangement.

The sled 31 of the above-mentioned swinging (with a pivot point) type
Are arranged on the front and rear sides of the moving body 8 and the like. Then, the sled 31 slides on the sloping ground 1 and the moving body 8 moves smoothly.

The movement of the moving body 8 in the vertical and horizontal directions is the same as in the first embodiment, and a description thereof will be omitted.

In the fourth embodiment of the present invention, as shown in FIGS. 7 and 8, the moving body 8 is provided with a front wheel 41 and a rear wheel 41 which are separately driven and can be steered. is there.

The above-mentioned steering is performed on the driver's seat 4 on the moving body 8.
2 to drive the wheels respectively via known means by the onboard engine. Then, even if there is a slight undulation on the sloped land 1, the movement becomes easy, and the vehicle can travel on the road.

The first winch 6 for the moving body 8
The extension of the center wire 10 and the side wires 7, 7, 13, 13 by the second winch 9 and the third winch 12 is the same as that of the first embodiment, and the description is omitted.

In addition, the lifting of the wire of the winch (not shown) on the moving body 8 by the reaction force against the sloped land 1 at the time of drilling can be stopped by stopping the wire on the sloped ground 1 by appropriate means and by tightening the wire.

[0037]

According to the present invention, since the above-described method and configuration are adopted, the moving body can be floated on the sloping ground and moved vertically and horizontally.

[0038] Therefore, even if obstacles such as undulations and rocks are present on the sloped land, they can be moved smoothly. In addition, the movable body can be smoothly moved by the swing type wheels and sleds.

Further, the front and rear wheels, which are separately driven and steerable, make it easy to move the moving body even if there is undulation on the sloping ground. Can be eliminated.
