JP6280886B2 - Slope working vehicle - Google Patents

Description

  The present invention relates to a slope working vehicle capable of moving a slope on which a slope frame is formed and capable of forming a lock bolt insertion hole and a ground anchor insertion hole.

  Conventionally, as a slope working vehicle that is swung with a winch wire and runs on a slope or a frame and forms a lock bolt insertion hole, etc., the slope is moved to the left and right. Device that can move the lock bolt insertion hole only in the part where the work vehicle body is located (see Patent Document 1), An apparatus capable of drilling without moving to (see Patent Document 2) is known.

  However, in an apparatus that can move the work vehicle body itself in the left-right direction and drill the lock bolt insertion hole only in the part where the work vehicle body is located, it is slightly away from the position where the current drilling operation is performed. When it is desired to drill the lock bolt insertion holes at the left and right positions, the drilling work must be performed after the work vehicle body is moved in the left-right direction, which has the disadvantage of poor work efficiency.

  In addition, in an apparatus that can drill holes without rotating the arm in the horizontal direction and moving in the horizontal direction, the lock bolt insertion hole can be formed without moving the work vehicle body or the like to the left or right. Since the device is not in a state of facing the slope, the lock bolt insertion hole perpendicular to the slope cannot be drilled. There was a drawback that the angle of the lock bolt insertion hole drilled without rotating was not constant.

It is composed of an anti-wheel removal roller 15 that is attached to the side wall of the normal frame 2a below the tire 7 by the position adjusting means 14 during the slope movement and prevents the tire 7 from deviating from the normal frame 2a. Yes.

The tire attachment portion 4 includes a tire attachment portion main body 17 attached via a hydraulic cylinder 16 serving as a tire attachment portion expansion / contraction mechanism 5 that expands and contracts in the left-right direction on the front and rear left and right portions of the work vehicle main body 3, and the tire attachment One end is attached to the front and rear of the body 17, and the tire 7 is attached to the other end. The tire mounting portion main bodies 17 and 17 can be expanded and contracted in the left-right direction by the hydraulic cylinder 16 in accordance with the width of the frame 2a. In addition, the cylinder 6 that expands and contracts in the vertical direction can run on the frame while the tire 7 is expanded and contracted in the vertical direction according to the inclination and unevenness of the frame 2a and the work vehicle body 3 is stabilized.

The rear end of the arm 9 is attached to the rear position of the work vehicle main body 3 so as to be turnable in the left-right direction via an arm rotation shaft 18, and the arm 9 is turned to the side of the arm 9 in the left-right direction. A hydraulic cylinder 19 to be moved is attached.
One end of the support bar 20 is fixedly provided at the bottom near the tip of the arm 9, and the other end of the support bar 20 is connected to an arc-shaped rail 21 provided in front of the work vehicle body 3. It is slidably mounted. The support bar 20 supports the load applied to the tip of the arm 9.

  The support base 10 is attached to the tip of the arm 9 via a support base rotation shaft 22 that can rotate in the left-right direction, and a hydraulic cylinder 23 that rotates the support base in the left-right direction on the side surface of the support base. Is attached. Further, a guide shell mounting portion 11 provided on the support base 10 via a guide shell mounting portion rotating shaft 24 that can be rotated in the vertical direction, and a hydraulic cylinder 25 that rotates the guide shell mounting portion 11 in the vertical direction. And. A guide shell 12 is fixed to the upper portion of the guide shell mounting portion 11.

It is comprised with the engine 29 to drive. The engine 29 is rotatably provided at the rear part of the work vehicle main body, so that the engine 29 can be kept horizontal even during slope driving. Further, by providing the engine 29 at a low position (for example, the center of the work vehicle main body 3 and the center of the engine 29 are substantially the same height), the center of gravity of the work vehicle main body 3 as a whole can be lowered, and stability can be improved. Can be increased.

  The position adjusting means 14 is configured to be able to move the derailment prevention roller 15 in the vertical direction by attaching the derailment prevention roller 15 to the tip of the position adjusting hydraulic cylinder 30 attached to the inside of the cylinder 6. Is.

  At the time of running the frame, the derailment prevention roller 15 is positioned so as to protrude downward from the tire 7, thereby bringing the derailment prevention roller 15 into contact with the legal frame side wall under the tire 7. Thereby, it will be in the state where the tire 7 and the wheel-rolling prevention roller 15 pinch | interpose a legal frame, and it can prevent that the tire 7 is always located on a legal frame and derails from the legal frame 2a.

  Further, when the distance between the legal frames 2 becomes wider or narrower during traveling, the derailment prevention roller 15 can be brought into contact with the legal frame side wall under the tire 7 by the hydraulic cylinder 16 that expands and contracts in the left-right direction. .

When traveling on the ground (including slopes where no frame is installed), the position adjustment hydraulic cylinder 30 is contracted so that the wheel removal preventing roller 15 is positioned above the lower part of the tire. The traveling of the surface work vehicle 1 is not hindered.
In addition, since the tire 7 has a diameter dimension that is twice or more the height dimension of the method frame 2a, the tire 7 can easily get over the method frame 2a.

  When working on the slope where the slope frame 2a is installed, the slope working vehicle 1 is positioned at the lower part of the slope, and the tips of the wires 31 of the left and right winches 8 are reversed to the main anchor 32 at the upper part of the slope. Fix it in the shape of a letter. When the wire 31 is fixed to the main anchor 32, the winch 8 is wound up and advanced. In addition, the tire attachment part expansion / contraction mechanism 5 is extended / contracted in the left / right direction so that the four tires 7 are respectively placed on the normal frame 2a, and the tire attachment part is adjusted so that the left / right distance of the tire 7 and the width of the normal frame 2 are matched. 4 should be adjusted.

  After each of the four tires 7 rides on the method frame 2 a, the position adjusting hydraulic cylinder 30 is extended to bring the wheel removal prevention roller 15 into contact with the method frame side wall below the tire 7. At this time, the position in the lateral direction of the wheel removal preventing roller 15 may be finely adjusted by expanding / contracting the tire mounting portion expansion / contraction mechanism 5 in the left-right direction.

  The slope working vehicle 1 can also move the slope frame to the left and right by extending and retracting the tire mounting portion extension mechanism 5 in the left and right direction.

  When the slope working vehicle 1 arrives at the work position, the hole drilling device 13 is rotated to a predetermined angle. Thereafter, the rod 27 and the bit 28 are hit and rotated by the hydraulic drifter 26, and the lock bolt insertion hole and the like are drilled.

  In the case where a lock bolt insertion hole or the like is further formed in the left and right positions of the lock bolt insertion hole or the like formed by the drilling operation, as shown in FIG. As shown, the support base 10 is rotated in the left-right direction so that the guide shell mounting portion 11 and the guide shell 12 are substantially parallel to the work vehicle body 3. By rotating the support base 10 in this manner, the hole drilling device 13 is in a state of facing the slope and can be drilled so as to be orthogonal to the slope. Therefore, a plurality of lock bolt insertion holes and the like can be easily formed at substantially the same angle in the left-right direction without moving the work vehicle body 3 in the left-right direction.
