Description

本発明は法枠が形成された傾斜面を確実に移動でき、ロックボルトの施工等を行うことができる法面作業車に関する。 The present invention relates to a slope working vehicle that can reliably move an inclined surface on which a frame is formed, and that can perform construction of a lock bolt and the like.

従来、法枠が設けられた法面において、ウインチのワイヤーで牽吊されて法枠上を走行し、作業を行う作業車については、車輪を設けて法枠上を走行する作業車や、ゴム製の無限軌道を設けて法枠上を走行する作業車（特許文献１参照）等が知られている。
しかし、法枠が法面に対して平行ではなく、法枠の幅方向に傾斜していたり、法枠がねじれ状態で設置されていることがあり、このような法枠上を走行すると、単にタイヤを設けただけの法枠作業車では脱輪してしまう可能性があった。脱輪を防止するためには、ワイヤーを固定する主アンカーを法枠の傾斜やねじれに合わせて変更し、ウインチで牽引する角度を変更しながら走行しなければならず、多大な労力を必要としていた。
また、ゴム製の無限軌道を設けた作業車であれば、多少のねじれ等は無視して走行することができるものの、法枠を傷つけてしまうおそれがあった。 Conventionally, on work slopes where a frame is provided, a work vehicle that is swung with a winch wire and runs on the frame and works, a work vehicle that is provided with wheels and runs on the frame, rubber 2. Description of the Related Art A work vehicle (see Patent Document 1) that travels on a legal frame with a made endless track is known.
However, the frame may not be parallel to the plane, but may be inclined in the width direction of the frame, or the frame may be installed in a twisted state. There is a possibility that the wheel will be removed from a frame work vehicle that only has tires. To prevent derailment, it is necessary to change the main anchor that fixes the wire according to the inclination and twist of the frame and to change the angle pulled by the winch, which requires a lot of labor. It was.
Further, a working vehicle provided with a rubber endless track can travel while ignoring some twists and the like, but there is a risk of damaging the legal frame.

以下、図面に示す本発明を実施するための形態により、本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

図１ないし図８に示す本発明を実施するための第１の形態において、１は法枠２が形成された急斜面で作業可能な法面作業車で、該法面作業車１は作業車本体３と、該作業車本体３の左右部位に設けられたタイヤ取付部４、４と、該タイヤ取付部４、４を法枠２の幅に合わせて伸縮させることができるタイヤ取付部伸縮機構５、５と、前記タイヤ取付部４、４に取り付けられたタイヤ６、６、６、６と、前記タイヤ取付部４、４に位置調整手段７を介して取り付けられた脱輪防止ローラー８、８、８、８と、前記作業車本体３に取り付けられたウインチ９と、前記作業車本体３の上面に垂直方向に回動できる支持台１０を介して取り付けられた削孔装置１１とで構成されている。 In the first embodiment for carrying out the present invention shown in FIGS. 1 to 8, reference numeral 1 denotes a slope working vehicle capable of working on a steep slope formed with a slope frame 2, and the slope working vehicle 1 is a work vehicle main body. 3, tire mounting portions 4, 4 provided on the left and right parts of the work vehicle main body 3, and a tire mounting portion expansion / contraction mechanism 5 that can expand / contract the tire mounting portions 4, 4 according to the width of the frame 2. 5, tires 6, 6, 6, 6 attached to the tire attaching portions 4, 4, and wheel removal prevention rollers 8, 8 attached to the tire attaching portions 4, 4 via position adjusting means 7. 8, 8; a winch 9 attached to the work vehicle main body 3; and a drilling device 11 attached to the upper surface of the work vehicle main body 3 via a support base 10 that can be rotated in the vertical direction. ing.

前記タイヤ取付部４は、前記作業車本体３の前後の左右部位に左右方向に伸縮するタイヤ取付部伸縮機構５としての油圧シリンダー１２、１２を介して取り付けられたタイヤ取付部本体１３、１３と、該タイヤ取付部本体１３、１３の前後に一端が取り付けられ、他端にタイヤ６、６、６、６が取り付けられるタイヤ取付軸１４、１４、１４、１４と、該タイヤ取付軸１４、１４、１４、１４を上下方向に伸縮させる油圧シリンダー１５、１５、１５、１５で構成されている。タイヤ取付部本体１３、１３は法枠２の幅に合わせて油圧シリンダー１２により左右方向に伸縮できるものである。また、上下方向に伸縮する油圧シリンダー１５、１５、１５、１５は法枠２の傾斜や凹凸に合わせてタイヤ取付軸１４、１４、１４、１４を上下方向に伸縮させ、作業車本体３を安定させた状態で法枠上を走行できるものである。 The tire mounting portion 4 includes tire mounting portion main bodies 13 and 13 mounted via hydraulic cylinders 12 and 12 serving as a tire mounting portion expansion and contraction mechanism 5 that expands and contracts in the left and right portions of the front and rear of the work vehicle main body 3. The tire attachment shafts 14, 14, 14, 14 are attached to the front and rear of the tire attachment portion main bodies 13, 13 and the tires 6, 6, 6, 6 are attached to the other ends, and the tire attachment shafts 14, 14 , 14, 14 are constituted by hydraulic cylinders 15, 15, 15, 15 that expand and contract in the vertical direction. The tire attachment main bodies 13 and 13 can be expanded and contracted in the left-right direction by the hydraulic cylinder 12 in accordance with the width of the frame 2. Further, the hydraulic cylinders 15, 15, 15, 15 that expand and contract in the vertical direction extend the tire mounting shafts 14, 14, 14, 14 in the vertical direction according to the inclination and unevenness of the frame 2 to stabilize the work vehicle body 3. It is possible to travel on the legal frame in the state of being allowed to.

前記位置調整手段７は、前記タイヤ取付軸１４、１４、１４、１４の内側に取り付けられた位置調整用油圧シリンダー１６、１６、１６、１６の先端に脱輪防止ローラー８を取り付けることにより、脱輪防止ローラー８、８、８、８を上下方向に移動できるように構成したものである。 The position adjusting means 7 is attached to the tip of the position adjusting hydraulic cylinders 16, 16, 16, 16 attached to the inside of the tire mounting shafts 14, 14, 14, 14. The ring prevention rollers 8, 8, 8, and 8 are configured to be movable in the vertical direction.

法枠走行時は、脱輪防止ローラー８、８、８、８をタイヤ４よりも下方へ突出した状態に位置させることにより、脱輪防止ローラー８、８、８、８をタイヤ６下部の法枠内壁２ａに当接させる。これにより、タイヤ４と脱輪防止ローラー８、８、８、８が法枠を挟み込むような状態となり、タイヤ４が常に法枠上に位置し、法枠２から脱輪することを防止できる。 At the time of running the frame, the wheel removal preventing rollers 8, 8, 8, 8 are positioned so as to protrude downward from the tire 4, so that the wheel removal preventing rollers 8, 8, 8, 8 are disposed below the tire 6. The frame is brought into contact with the inner wall 2a. As a result, the tire 4 and the derailment prevention rollers 8, 8, 8, 8 are in a state of sandwiching the legal frame, and the tire 4 is always located on the legal frame and can be prevented from being derailed from the legal frame 2.

なお、地面（法枠の設置されていない法面等も含む）走行時は、位置調整用油圧シリンダー１６、１６、１６、１６を縮めてタイヤ下部よりも上方に脱輪防止ローラー８、８、８、８を位置させ、脱輪防止ローラー８、８、８、８が法面作業車１の走行を妨げないようにする。 When traveling on the ground (including slopes where no frame is installed), the position adjusting hydraulic cylinders 16, 16, 16, 16 are shrunk so that the wheel removal prevention rollers 8, 8, 8 and 8 are positioned so that the derailment prevention rollers 8, 8, 8, 8 do not disturb the running of the slope work vehicle 1.

また、走行中に法枠２の間隔が広くなったり狭くなった場合には、左右方向に伸縮する油圧シリンダー１２、１２により脱輪防止ローラー８、８、８、８をタイヤ６下部の法枠側壁２ａに当接させることができる。 In addition, when the interval between the frame 2 becomes wider or narrower during traveling, the derailment prevention rollers 8, 8, 8, 8 are attached to the frame below the tire 6 by the hydraulic cylinders 12, 12 that extend in the left-right direction. It can be brought into contact with the side wall 2a.

前記削孔装置１１は、前記支持台１０に回動可能に取り付けられたガイドシェル１７と、該ガイドシェル１７上をスライド移動する油圧ドリフター１８と、該油圧ドリフター１８に取り付けられたロッド１９と、該ロッド１９の先端部に取り付けられたビット２０とで構成されている。 The drilling device 11 includes a guide shell 17 rotatably attached to the support base 10, a hydraulic drifter 18 that slides on the guide shell 17, and a rod 19 attached to the hydraulic drifter 18; It comprises a bit 20 attached to the tip of the rod 19.

法枠２が設置された法面で作業を行なう場合、法面作業車１を法面の下部に位置させ、ウインチ９のワイヤー２１の先端部を法面上部の主アンカー２２に固定する。主アンカー２２にワイヤー２１を固定したらウインチ９を巻き上げて前進させる。なお、４輪のタイヤ６、６、６、６がそれぞれ法枠２の上に乗るように、タイヤ取付部伸縮機構５を左右方向に伸縮させ、タイヤ６、６、６、６の左右間隔と法枠２の幅が合うようにタイヤ取付部４、４を調整しておく。 When working on the slope where the slope frame 2 is installed, the slope working vehicle 1 is positioned at the lower part of the slope and the tip of the wire 21 of the winch 9 is fixed to the main anchor 22 at the upper part of the slope. When the wire 21 is fixed to the main anchor 22, the winch 9 is wound up and advanced. In addition, the tire attachment part expansion / contraction mechanism 5 is expanded / contracted in the left / right direction so that the four-wheel tires 6, 6, 6, 6 are respectively on the frame 2, and the left / right distance between the tires 6, 6, 6, 6 The tire mounting portions 4 and 4 are adjusted so that the width of the legal frame 2 matches.

４輪のタイヤ６、６、６、６がそれぞれ法枠２の上に乗りあげた後、位置調整用油圧シリンダー１６、１６、１６、１６を伸長し脱輪防止ローラー８、８、８、８をタイヤ６、６、６、６下部の法枠内壁２ａに当接させる。この時、タイヤ取付部伸縮機構５を左右方向に伸縮させて脱輪防止ローラー８、８、８、８の横方向の位置を微調整してもよい。 After the four tires 6, 6, 6, 6 ride on the legal frame 2, the position adjusting hydraulic cylinders 16, 16, 16, 16 are extended to prevent the wheel removal preventing rollers 8, 8, 8, 8. Is brought into contact with the inner wall 2a of the lower frame of the tire 6,6,6,6. At this time, the lateral position of the wheel removal preventing rollers 8, 8, 8, 8 may be finely adjusted by expanding / contracting the tire attaching / contracting mechanism 5 in the left-right direction.

脱輪防止ローラー８、８、８、８がタイヤ下部の法枠内壁に当接したら、ウインチ９を更に巻き上げ、作業を行いたい位置まで法面作業車１を走行させる。なお、法枠の横桟を通過する際には横桟を通過する脱輪防止ローラー８を上方へ移動させるが、他の脱輪防止ローラー８のいずれかが常にタイヤ下部の法枠内壁２ａに当接しているので、法枠２にねじれや傾斜があっても、確実に法枠上を走行することができる。 When the derailment prevention rollers 8, 8, 8, 8 come into contact with the inner wall of the lower frame of the tire, the winch 9 is further wound up and the slope work vehicle 1 is moved to the position where the work is desired. In addition, when passing the horizontal beam of the frame, the anti-roller prevention roller 8 passing through the horizontal beam is moved upward, but any of the other anti-roller rollers 8 always moves to the frame inner wall 2a below the tire. Since they are in contact with each other, even if the frame 2 is twisted or inclined, the vehicle can reliably travel on the frame.

作業位置に法面作業車１が到着したら、削孔装置１１を所定の角度に回動させる。その後、油圧ドリフター１８のよりロッド１９およびビット２０に打撃および回転を与え、ロックボルト用孔を削孔する。 When the slope working vehicle 1 arrives at the work position, the hole drilling device 11 is rotated to a predetermined angle. Thereafter, the rod 19 and the bit 20 are struck and rotated by the hydraulic drifter 18 to drill the hole for the lock bolt.

なお、本実施の形態の法面作業車１は、タイヤ取付部伸縮機構５を左右方向に伸縮させることにより、法枠を左右に移動することもできる。 Note that the slope work vehicle 1 of the present embodiment 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.
