  In the drilling device described in Patent Document 1, since it is not necessary to assemble a scaffold with respect to the frame, the construction cost is reduced by that amount, but a drilling hole can be formed only within the range of the boom, and Since it is necessary to install a crane under the legal frame, there is a problem that a drilling hole cannot be formed unless the site is limited.

  Further, as described in Patent Document 2, when the work vehicle is raised and lowered with the lifting wire, if the angle of the lifting wire extending from the movable pulley to both sides with respect to the vertical direction of the inclined ground is different with respect to the left and right lifting wires, There is a problem that the operating force of the lifting wire at the time acts on the work vehicle in an unbalanced manner so that the work vehicle cannot be lifted up and down properly with respect to the slope.

  An object of the present invention is to provide an inclined work facility that is excellent in versatility and that can be moved up and down with high accuracy along a vertical frame of a method frame.

An inclined terrain work facility according to the present invention is an inclined terrain work facility provided with a self-propelled drilling work vehicle and an elevating device capable of moving the drilling work vehicle up and down along a drilling region on an inclined land. The lifting device includes a fixed point provided on both sides of the sloped land on the mountain side of the drilling region, a lifting winch installed on one side of the valley side of the sloped land, and one of the lifting winch side A fixed pulley attached to a fixed point; a lifting wire which is fed out from the lifting winch and hooked on the fixed pulley and is spaced apart from the lifting winch; An angle with respect to the vertical direction of the sloping ground of the moving pulley that is hooked on the middle portion of the lifting wire stretched between the pulley and the other fixed point and supports the drilling work vehicle, and the lifting wire extending from the moving pulley to both sides The left and right lift A wire angle adjusting means to adjust the substantially same for ya, to draw the to fixed pulley and the movable pulley or between other fixed points and at least one of the middle portion of the side of the lifting wire stretched between the movable pulley And a wire angle adjusting means having a wire tensioning device capable of adjusting the length of the adjusting wire .

  In this slope work facility, a fixed pulley is attached to one of the fixed points provided on both sides of the slope on the mountain side of the drilling area, and the end of the lifting wire is fixed to the other, and between the fixed pulley and the other fixed point. While hooking the moving pulley provided in the drilling work vehicle to the middle part of the lifting wire stretched on and lifting and lifting the lifting wire with the lifting winch, while supporting with the lifting wire, It is comprised so that a drilling work vehicle can be moved to an up-down direction along an inclined ground. In addition, the wire angle adjusting means can adjust the inclination angle of the inclined ground of the lifting wire extending from the movable pulley to the left and right sides substantially the same with respect to the left and right lifting wires, so that the drilling work vehicle can be adjusted by the lifting wires. When moving in the vertical direction, the pulling force of the lifting wire can be applied to the drilling work vehicle in a balanced manner, so that the drilling work vehicle can be moved in the vertical direction with high accuracy.

  Here, as the wire angle adjusting means, a wire clip that sandwiches the middle part of the lifting wire stretched between the other fixed point and the moving pulley, an adjusting wire connected to the wire clip, and the adjusting wire What has a wire tension device which can adjust the length of a wire can be used. In this case, the middle part of the lifting wire stretched between the other fixed point and the moving pulley is clamped by the wire clip, and the lifting wire is pulled by the wire tensioning device and extends to both sides of the moving pulley. The angle of the lifting wire will be adjusted. Then, in this state, the drilling work vehicle is lifted and lowered along the inclination direction of the sloping ground by winding or feeding the lifting wire with a winch.

As described above, the wire tensioning device pulls the one lifting wire through the adjusting wire to adjust the angle of the lifting wire extending to both sides of the movable pulley. Then, in this state, the drilling work vehicle is lifted and lowered along the inclination direction of the sloping ground by winding or feeding the lifting wire with a winch. Further, since the adjustment pulley moves along the lifting wire to the optimum load balance position, an excessive force does not act on the lifting wire and the adjustment wire.

In this case, the drilling machine can be moved to the left and right by the swing arm, and the drilling holes can be formed in two adjacent vertical frames, and the drilling holes can be formed in order along one vertical frame. In comparison, work efficiency can be greatly improved.

  According to the sloping ground work facility according to the present invention, the drilling work vehicle can be moved in the vertical direction along the sloping ground while being supported by the elevating wire. Even when it is wide in the vertical direction, it is possible to efficiently form a hole in an inclined ground without increasing the equipment cost. In addition, the wire angle adjusting means can adjust the inclination angle of the inclined wire extending in the vertical direction of the lifting wire extending from the movable pulley to the left and right sides substantially the same with respect to the right and left lifting wires. When moving in the vertical direction, the pulling force of the lifting wire can be applied to the drilling work vehicle in a balanced manner, so that the drilling work vehicle can be moved in the vertical direction with high accuracy.
