On the other hand, as shown in the side view of FIG. 4 and the plan view of FIG. 5, the slope excavator 5 has a crawler type lower traveling body 24 having a traveling hydraulic motor 24b on the left and right. The slope excavator 5 moves the lower traveling body 24 in a boat shape (that is, the front end a and the rear end b of the lower traveling body 24 aslant as shown in FIG. 4) so that the rocks on the slope 1 can easily travel over the rocks. ) Make up. As shown in the side view of FIG. 6, an upper vehicle body 25 is attached to a lower vehicle body 24a constituting a skeleton of the lower traveling body 24 so as to be rotatable about a rear pivot shaft 48, and a hydraulic cylinder is provided. By the extension of 49, the front portion of the upper body 25 can be lifted via the links 50 and 51. As a result, by lowering the rear of the upper body 25, the center of gravity of the slope excavator 5 moves rearward, The slope excavator 5 is stably supported on the slope.

Is mounted so as to be rotated by the bucket cylinder 35.

As shown in FIG. 5, the slope excavator 5 includes an electric motor 36a, a hydraulic pump 36 driven by the electric motor 36a, an oil cooler 37, and an oil tank 38 and control valve 3
9 and a receiver 47 for receiving an operation signal from an operation wireless transmitter 46 of the operator. The receiver 47 starts and stops the electric motor 36a, activates and stops the traveling hydraulic motor 24b under the control of the control valve 39, and controls the swing cylinder 27 and the multi-joint according to the operation signal received. The cylinders 30, 32, and 35 of the arm 29, the hydraulic cylinder 49 for raising and lowering the upper vehicle body 25, and the hydraulic cylinders 52 and 53 for raising and lowering outriggers 55 and 56 described later are remotely controlled.

The outriggers 55 and 56 are shown in FIG.
As shown in the side view of FIG. 7, before and after the lower vehicle body 24a,
Hydraulic cylinders 52, 53 around pivot shafts 61, 62
The left and right pairs are attached to each other so as to be rotated by the hydraulic cylinder 52 and the hydraulic cylinder 52 during excavation work.
By extending 53, these outriggers 5
5 and 56 are made to protrude below the lower surface of the lower traveling body 24 so as to be pressed against the slope 1. The outrigger 55 at the front is a lower traveling body 24 of the slope excavator 5.
By supporting the slope excavator 5 by projecting further to the front, the slope excavator 5 is prevented from tipping over, and the rear outrigger 56 is provided with the bucket 3
In the case of performing a crushing operation by attaching a hydraulic breaker instead of 4, it serves to support the slope excavator 5.

As shown in FIGS. 4 and 5, the slope excavator 5 has a pair of upper and lower brackets 40 and 41 on the right and left rear portions of the upper body 25, respectively. The bracket 42 detachably connected to the tip of the wire rope 4 has two sheaves 43, 44 on the left and right sides.
A wire rope 63 having both ends connected to 0 and 41,
Multiply by 64. The bracket 42 has a connector 57 for connecting the cable 18, and the connector 57 is connected to the electric motor 36 a via a telescopic cable 58.

When a slope is excavated by using such a slope excavator, the supporting machine 2 is disassembled and transported onto a traveling path 3 previously constructed on the upper part of the slope 1 by a cable crane, a helicopter, or the like, and assembled. Similarly, the slope excavator 5 is raised to the traveling path 3, and the wire rope 4 and the cable 18 of the support machine 2 are connected to the bracket 42 of the slope excavator 5.

Next, as shown in FIGS. 1 and 2, the operator of the support device 2 adjusts the amount of expansion and contraction of the boom 12 and places the platform 60 on the edge of the traveling path 3. On the other hand, the operator of the slope excavator 5 extends the hydraulic cylinder 49 by wireless remote control to incline the upper vehicle body 25 with respect to the lower vehicle body 24a, and operates the traveling hydraulic motor 24b of the slope excavator 5 to operate the slope excavator 5. Lower the excavator 5 along the slope. At the same time, the operator of the support machine 2 operates the winch 10 to pay out the wire rope 4, thereby lowering the slope excavator 5 while keeping the wire rope 4 stretched. When the slope excavator 5 reaches a position where the excavation work is to be performed, the hydraulic cylinders 52, 5
3 is extended, the outriggers 55 and 56 are lowered, and the slope excavator 5 is supported by the outriggers 55 and 56.

Here, since the wire rope 4 is unreeled from the sheave 11a at the tip of the boom 12 as the wire rope support, the wire rope 4
Can be made to protrude from the edge of the traveling path 3 toward the slope 1, whereby the mounting position of the wire rope support to the upper revolving structure is set to a low position, and the tension applied to the wire rope causes the support device 2 A structure that does not easily fall can be realized.

Further, since the boom 12 which is a wire rope support provided on the supporting machine 2 is constituted by a telescopic boom, the sheave 11a is expanded and contracted by expanding and contracting the boom 12.
That is, it can be easily adjusted so that the wire rope feeding position is located near the edge of the traveling path.

Since the wire rope 4 is not directly supported on the boom 12 but is supported on the ground via the base 60 at the end of the boom 12, an excessive force is applied to the boom 12 by the tension generated in the wire rope 4. Can be prevented, and the table 60 is pivotally supported and the height can be adjusted. Therefore, even if the table 60 moves with the movement of the boom 12, the positioning of the table 60 can be prevented. Can be easily performed, and it is possible to cope with slight inclination and unevenness of the installation position.

When the slope 1 is excavated by the slope excavator 5, the rock is prevented by the operator by rotating the articulated arm 29 and the bucket 34 forward by radio remote control in a state where the wire rope 4 prevents the fall and the fall. This is done by jumping forward and dropping. This makes it possible to move the slope excavator 5 from above to below to scrape off rocks and the like remaining on the slope 1 efficiently.

During excavation by the slope excavator 5, an outrigger 55 projecting forward from the lower traveling body 24 at the front of the upper vehicle body 25 is projected downward from the lower traveling body 24 to be supported on the slope 1, whereby The excavation reaction force is received by the outrigger 55 to prevent the slope excavator 5 from falling forward.

Also, at the time of excavation, as shown in FIG. 1, the rear of the upper body 25 of the slope excavator 5 is lowered with respect to the lower body 24a, so that the center of gravity of the slope excavator 5 is moved rearward to excavate the slope. The machine 5 is prevented from turning forward.

Further, since the arm cylinder 32 and the bucket cylinder 35 of the multi-joint arm 29 are mounted on the lower surface of the multi-joint arm 29, when the slope excavator 5 is positioned on the slope 1 as shown in FIG. When the center of gravity of the multi-joint arm 29 is close to the slope, and the excavation work is performed on the slope by the multi-joint arm, the excavator can reduce the overturning moment of the front excavator due to the own weight of the multi-joint arm or its excavation reaction force. Therefore, the work can be performed in a stable posture by receiving the excavation reaction force.

The ascending and descending of the slope excavator 5 on the slope 1 is performed by the support machine 2 via the wire rope 4.
The winch 10 is actuated in a state where the wire rope 4 is wound or unwound, and
This is performed by driving the lower traveling body of the slope excavator 5 to travel by remote control. In this case, the slope excavator 5
Is formed in a boat shape, so that even when relatively large rocks project on the slope 1, it is possible to ride over the rocks and pass over the rocks. There is no need to increase the size.

As shown in FIG. 8, the lateral movement of the slope excavator 5 is performed by moving the support machine 2 on the travel path 3 as indicated by an arrow a, and then moving the lower part of the slope excavator 5. Running body 2
4 is driven obliquely up (or down) on the slope 1 as shown by the arrow b, and at the same time, the wire rope 4 is wound (or fed) by the winch 10, and then the slope excavator 5 is moved. This is performed by lowering (or rising) as shown by arrow c. Thus, 1
When supported by the wire rope 4 from the direction, the position can be easily changed by a simple operation, as compared with the method in which the winding amount of the two winches is extended as described in the above-mentioned publication.

In the present embodiment, the turning device 8 of the supporting machine 2 is operated to change the direction of the boom 12 in FIGS.
The support point of the wire rope 4 can be moved in the lateral direction by changing the position as shown in FIG. 5, so that the control range of the support point of the wire rope can be expanded and the support point can be easily adjusted.

The present invention can be used not only for crushing and collapsing a slope by blasting but also for removing rocks and earth and sand on a relatively gentle slope having a slope of, for example, about 30 degrees.

Further, the support device of the slope excavator 5 with the wire rope 4 may be constituted, for example, by installing a rail on the upper part of the slope 1 and movably installing a winch wheel along the rail. Further, a wire rope may be drawn out from a winch device in which an articulated arm, a telescopic boom, and the like are attached to a swivel fixed to the upper part of the slope 1. Further, as shown in FIG. 9, the supporting machine 2 can be used as a machine for supporting another slope excavator , such as a machine for attaching a breaker 59 to the tip of the articulated arm 29A to crush rock on a slope. . Further, a backhoe bucket can be used as a bucket to be attached to the multi-section arm.
