Further, the elevating portion 221 has a structure in which the length of the second leg portion below the fixing portion 32 with the horizontal member 3 can be changed.

FIG. 4 is a diagram for explaining a flow in which the first leg 21 and the second leg 22 of the mobility aid 1 are relatively moved with respect to the hole h1 drilled by the drilling machine 7. be.

As shown in FIG. 4A, first, when the drilling of the hole h1 is completed, the elevating portions 211 and 221 of the first leg portion 21 and the second leg portion 22 are raised to raise the drilling machine. It is assumed that only the leg of 7 is in contact with the slope. That is, the elevating portions 211 and 221 are in the first state. (With the legs of the drilling machine in contact with the slope, raise the first elevating part and the second elevating part, and separate the first leg and the second leg from the slope. Step to set the position (1))

(Step of sliding the slide portion to move the first leg portion and the second leg portion relative to the slope (2))

As shown in FIG. 4C, the elevating portions 211 and 221 are then lowered so that the first leg portion 21 and the second leg portion 22 come into contact with the slope, and the legs of the drilling machine 7 are formed. The part 71 rises and floats in the air. That is, the elevating portions 211 and 221 are in the third state. (Step of lowering the first elevating part and the second elevating part, bringing the first leg part and the second leg part into contact with the slope, and separating the leg part of the drilling machine from the slope. (3))

FIG. 5 is a diagram for explaining a flow of moving the drilling machine 7 from the position of the hole h1 in order to arrange the hole h2 for drilling after FIG.

As shown in FIG. 5A, next, the slide portion 4 is moved to the right (positive X direction), and the drilling machine 7 connected to the slide portion 4 is moved in the X direction with respect to the slope. Move to. (Step of sliding the slide portion to move the drilling machine relative to the slope (4))

As shown in FIG. 5B, the drilling machine 7 is relatively lowered by raising the elevating portions 211 and 221 next. As a result, the first leg portion 21, the second leg portion 22, and the leg portion 71 of the drilling machine 7 are in contact with the slope. That is, the elevating portions 221 and 221 are in the second state. (Step of raising the first elevating part and the second elevating part to bring the legs of the drilling machine into contact with the slope (5))

By using the drilling machine 7 in the arrangement shown in FIG. 5B, the hole h2 can be drilled.

Further, the movement amount of the drilling machine 7 can be adjusted according to the movement amount of the slide portion 4 with respect to the horizontal member 3, and it is also suitable for fine adjustment of the movement amount.

When constructing slopes, double drilling, which is superior in the reliability of the anchor effect, may be required. In the case of a conventional device for drilling a single hole, a device having a weight of about 60 kg can be used. For this reason, even with a method such as the CTB method in which the wire is appropriately hung, it is easy for the operator to lift it on the spot and adjust the position.

However, the device for performing double drilling is very heavy, and it is necessary to use a device having a weight of, for example, 500 to 700 kg. A device that performs such double drilling has a weight that is difficult for an operator to lift, and the position cannot be adjusted. The mobility aid of the present invention is a device that makes it easy to adjust the drilling position of the double drilling machine and slope work that adjusts the drilling position even in slope work using a heavy double drilling machine. Suitable for the method.

Further, FIG. 6 is a diagram for explaining a state in which the connecting portion 5 is connected by rotating the direction of the drilling machine 7 by the rotating portion 6.

The support rod of the drilling machine 7 is fitted and fixed in the opening 51 of the connecting portion 5. The orientation of the drilling machine 7 in the opening 51 can be adjusted by the rotating portion 6. The rotating portion 6 is a disk-shaped member, and has holes 61a to 61g (FIG. 6B) in the circumferential direction around a portion corresponding to the opening 51. The disk-shaped member of the rotating portion 6 is fixed to the drilling machine 7 and attached so as not to move in the horizontal plane (XY direction) with the drilling machine 7.

FIG. 6A is for explaining a fixed state for moving the drilling machine 7 in the X direction. In FIG. 6A, the direction of the connecting portion 5 and the rotating portion 6 is fixed by pinning the hole 61d to the hole 5 of the connecting portion 5. As a result, the direction between the first leg 21 and the second leg 22 on which the connecting portion 5 is provided becomes the X direction. If the drilling machine 7 is moved by using the movement aid 1 in this state, it can be moved in the X direction. That is, the drilling machine 7 can be moved in the horizontal direction of the slope.

Next, FIG. 6B shows a state in which the hole 61 g of the rotating portion 6 is pinned to the hole 52 of the connecting portion 5. If fixed in this direction, the direction between the first leg 21 and the second leg 22 becomes the Y direction. If the drilling machine 7 is moved by using the movement aid 1 in this state, it can be moved in the Y direction. That is, the drilling machine 7 can be moved in the vertical direction of the slope.

Next, FIG. 6C shows a state in which the hole 6c of the rotating portion 6 is pinned. If fixed in this direction, the direction between the first leg 21 and the second leg 22 becomes an oblique direction. If the drilling machine 7 is moved in this state, it can be moved in the F1 direction. Further, FIG. 6D shows a state of being pinned by the hole 61f. If the drilling machine 7 is moved in this state, it can be moved in the F2 direction.

In this way, by providing the rotating portion 6 so that the directions of the movement assisting machine 1 and the drilling machine 7 can be adjusted, the moving direction of the drilling machine 7 using the movement assisting machine 1 can be arbitrarily set. It can also be adjusted to.

[Height adjustment unit 212, 222]

FIG. 7 is a diagram for explaining height adjustment using the height adjusting units 212 and 222. The slope is a rocky place or the like, and is not always flat and may have irregularities, and the slope may not be easily processed. On a slope with such unevenness, there may be a difference in height between the bottom surface on the first leg 21 side and the bottom surface on the second leg 22 side.

In such a case, as the height adjusting portions 212 and 222, the holes in the columnar members of the first leg portion 21 and the second leg portion 22 and the positions for pinning the horizontal member 3 can be changed. , Can be adjusted according to the condition of the slope. In FIG. 7, the work is performed on a slope where the first leg 21 side is lower than the second leg 22 side. Therefore, on the first leg 21 side, the fixing portion 31 of the horizontal member 3 is pinned by using the holes in the second step from the upper step of the height adjusting portion 212. On the other hand, on the second leg portion 22 side, the fixing portion 32 of the horizontal member 3 is pinned by using the holes in the fifth step from the upper step of the height adjusting portion 222. As a result, the arrangement of the basic heights of the first leg 21 and the second leg 22 of the mobility aid 1 can be adjusted, and the drilling machine 7 is perpendicular to the slope. It is easy to control the posture so as to drill holes.

FIG. 8 is a schematic view for making it easy to grasp the state when the slope drilling device 10 is used on a slope. FIG. 8A is a side view of the slope, and FIG. 8B is a front view of the slope.
