Description of the Related Art There is known a device (see Patent Document 1) that has a direction moving device and can drill a lock bolt insertion hole at a site where a work vehicle main body is located.

しかしながら、作業車本体自体を左右方向に移動させ、作業車本体が位置している部位にロックボルト挿入孔を削孔することができる装置であっても、作業車本体が法面に対して平行状態でない場合には、法面に対して直交するロックボルト挿入孔等を形成することが困難であった。   However, even if the work vehicle main body itself is moved in the left-right direction and the lock bolt insertion hole is drilled in the part where the work vehicle main body is located, the work vehicle main body is parallel to the slope. When it was not in a state, it was difficult to form a lock bolt insertion hole or the like orthogonal to the slope.

The up-down direction is a direction in which the work vehicle body is raised and lowered, the left-right direction indicates the left-right direction in plan view (FIGS. 2 and 4), and the front-rear direction indicates the up-down direction in plan view.

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は図３及び図４に示すように法枠２ａが形成された法面２で作業可能な法面作業車である。   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 slope 2 in which a slope 2a is formed as shown in FIGS. is there.

この法面作業車１は図１に示すように、作業車本体３と、該作業車本体３の左右部位に設けられ、法枠の幅に合わせて伸縮させることができる伸縮機構４と、該伸縮機構４の前後部位に、それぞれ上下方向に伸縮可能なタイヤ用油圧シリンダー５を介して設けられたタイヤ６と、前記作業車本体３に取り付けられたウインチ７と、前記作業車本体３の底面にそれぞれ上下方向に伸縮可能な支持具用油圧シリンダー８を介して設けられ、前記伸縮機構４が左右方向に伸縮する際に作業車本体３を支持可能な複数の支持具９と、前記作業車本体３の底面部の前後左右方向に設けられた複数個（例えば４個）のセンサー１０と、該センサー１０の信号を受信し、該信号に基づいて作業車本体３が法面２又は法枠２ａに対して略平行となるように、前記タイヤ６が設けられたタイヤ用油圧シリンダー５の作動杆５ａを伸縮させる制御手段１１と、前記作業車本体３に設けられた削孔装置１２と、前記タイヤ６の近傍に、それぞれ位置調整手段１３を介して取り付けられた脱輪防止ローラー１４とで構成されている。   As shown in FIG. 1, the slope working vehicle 1 includes a work vehicle main body 3, a telescopic mechanism 4 that is provided on the left and right parts of the work vehicle main body 3, and can be expanded and contracted according to the width of the slope frame, A tire 6 provided on each of the front and rear parts of the telescopic mechanism 4 via a hydraulic cylinder 5 for a tire that can be vertically expanded and contracted, a winch 7 attached to the work vehicle main body 3, and a bottom surface of the work vehicle main body 3 And a plurality of support tools 9 that can support the work vehicle body 3 when the extendable mechanism 4 extends and contracts in the left-right direction, and the work vehicle. A plurality of (for example, four) sensors 10 provided in the front / rear / right / left direction of the bottom surface of the main body 3 and signals of the sensors 10 are received, and the work vehicle main body 3 is connected to the slope 2 or the frame based on the signals. 2a so that it is almost parallel to the front Position adjusting means 13 in the vicinity of the control means 11 for expanding and contracting the operating rod 5 a of the tire hydraulic cylinder 5 provided with the tire 6, the drilling device 12 provided in the work vehicle main body 3, and the tire 6, respectively. It is comprised with the anti-wheel-removal roller 14 attached via.

前記伸縮機構４は、前記作業車本体３の左右部位に左右方向に伸縮する伸縮機構用油圧シリンダー１５を介して取り付けられたタイヤ取付部１６と、該タイヤ取付部１６の前後部位に一端が取り付けられ、他端（作動杆５ａ）にタイヤ６が取り付けられる上下方向に伸縮可能なタイヤ用油圧シリンダー５とで構成されている。タイヤ取付部１６は法枠２ａの幅に合わせて伸縮機構用油圧シリンダー１５により左右方向に伸縮できるものである。
前記センサー１０は、作業車本体３の前後左右方向に設けられた平行度センサーで、本実施形態では、非接触型の光学式センサーを用いており、この光学式センサーで測定された作業車本体３と法面２又は法枠２ａとの測定値（距離）を制御手段１１へ出力する。該制御手段１１との接続方法は有線又は無線が考えられるが、本実施の形態においては、無線で制御手段１１に接続されている。The telescopic mechanism 4 has a tire mounting portion 16 attached to the left and right portions of the work vehicle body 3 via a telescopic mechanism hydraulic cylinder 15 that stretches in the left-right direction, and one end attached to the front and rear portions of the tire mounting portion 16. The other end (operating rod 5a) includes a tire hydraulic cylinder 5 that can be expanded and contracted in the vertical direction. The tire mounting portion 16 can be expanded and contracted in the left-right direction by the expansion / contraction mechanism hydraulic cylinder 15 in accordance with the width of the frame 2a.
The sensor 10 is a parallelism sensor provided in the front-rear and left-right directions of the work vehicle main body 3. In the present embodiment, a non-contact optical sensor is used, and the work vehicle main body measured by the optical sensor is used. 3 and the measured value (distance) between the slope 2 or the frame 2a are output to the control means 11. The connection method with the control unit 11 may be wired or wireless. In the present embodiment, the connection unit is connected to the control unit 11 wirelessly.

前記制御手段１１は、前記センサー１０からの信号を受信し、前記センサー１０から送信された測定値の差から作業車本体３の法面２又は法枠２ａに対する傾きを算出し、この差が小さくなるように前記タイヤ６が設けられたタイヤ用油圧シリンダー５の作動杆５ａを伸縮させて法面２や法枠２ａと作業車本体３が略平行となるように制御する。本実施の形態においては、作業車本体３に制御手段１１は搭載せず、オペレーターが法面作業車を操作する操作端末（図示せず）に制御手段１１を搭載し、この制御手段１１に無線でセンサー１０からの信号を受信し、制御手段１１が自動で前記傾きの算出及びタイヤ用油圧シリンダー５の伸縮制御を行う。   The control means 11 receives a signal from the sensor 10, calculates the inclination of the work vehicle body 3 with respect to the slope 2 or the frame 2a from the difference between the measured values transmitted from the sensor 10, and the difference is small. The operating rod 5a of the tire hydraulic cylinder 5 provided with the tire 6 is expanded and contracted so that the slope 2 or the frame 2a and the work vehicle main body 3 are substantially parallel to each other. In the present embodiment, the control means 11 is not mounted on the work vehicle main body 3, but the control means 11 is mounted on an operation terminal (not shown) where the operator operates the slope work vehicle. Then, the signal from the sensor 10 is received, and the control means 11 automatically calculates the inclination and controls the expansion and contraction of the tire hydraulic cylinder 5.

なお、法面等の傾きが一定である場合等には、センサー１０として加速度センサー等を用いて、作業車本体３が一定の角度になるように制御してもよい。   When the slope of the slope or the like is constant, an acceleration sensor or the like may be used as the sensor 10 so that the work vehicle body 3 is controlled at a constant angle.

前記削孔装置１２は従来から使用されているもので、前記作業車本体３の前方上部に突出する取付け台１７に枢支ピン１８で回動可能に取付けられた支持台１９と、この支持台１９を回動させる支持台用油圧シリンダー２０と、前記支持台１９に左右方向に回動させる支持台用油圧モーター２１を用いた回動機構２２を介して取付けられたスイングブーム２３と、このスイングブーム２３の先端部に選択的に取付けられる、法面２に形成された法枠２ａにロックボルト挿入孔やグランドアンカー挿入孔を形成するガイドシェル２４および、このガイドシェル２４に取付けられた油圧ドリフター２５とで構成されている。   The hole drilling device 12 is conventionally used, and a support base 19 that is pivotally attached to a mounting base 17 protruding from the front upper portion of the work vehicle body 3 by a pivot pin 18, and the support base. A swing boom 23 attached via a support base hydraulic cylinder 20 for rotating the support base 19 and a rotation mechanism 22 using a support base hydraulic motor 21 for rotating the support base 19 in the left-right direction; A guide shell 24 that forms a lock bolt insertion hole and a ground anchor insertion hole in a slope frame 2 a formed on the slope 2 and is selectively attached to the tip of the boom 23, and a hydraulic drifter attached to the guide shell 24 25.

前記位置調整手段１３は、前記タイヤ用油圧シリンダー６の内側に取り付けられた位置調整用油圧シリンダー２６の先端に脱輪防止ローラー１４を取り付けることにより、位置調整用油圧シリンダー２６の作動杆２６ａを上下方向に伸縮させることにより、脱輪防止ローラー１４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 13 moves the operating rod 26a of the position adjusting hydraulic cylinder 26 up and down by attaching a derailment prevention roller 14 to the tip of the position adjusting hydraulic cylinder 26 attached to the inside of the tire hydraulic cylinder 6. By extending and contracting in the direction, the wheel removal preventing roller 14 can be moved in the vertical direction.

法枠走行時は、脱輪防止ローラー１４をタイヤ６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１４をタイヤ６下部の法枠側壁に当接させる。これにより、タイヤ６と脱輪防止ローラー１４が法枠を挟み込むような状態となり、タイヤ６が常に法枠上に位置し、法枠２ａから脱輪することを防止できる。
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伸縮機構４の伸縮機構用油圧シリンダー１５により脱輪防止ローラー１４をタイヤ６下部の法枠側壁に当接させることができる。During running of the frame, the wheel removal preventing roller 14 is positioned so as to protrude downward from the tire 6, so that the wheel removal preventing roller 14 is brought into contact with the wall of the method frame below the tire 6. Thereby, it will be in the state which the tire 6 and the wheel-rolling prevention roller 14 pinch | interpose a legal frame, and it can prevent that the tire 6 is always located on a legal frame and derails from the legal frame 2a.
In addition, when the distance between the legal frames 2 becomes wider or narrower during traveling, the derailment prevention roller 14 is moved by the hydraulic cylinder 15 for the expansion / contraction mechanism 4 that expands / contracts in the left / right direction. It can be made to contact.

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２６を縮めてタイヤ６下部よりも上方に脱輪防止ローラー１４を位置させ、脱輪防止ローラー１４が法面作業車１の走行を妨げないようにする。
なお、タイヤ６は法枠２ａの高さ寸法の２倍以上の直径寸法を有しているので、法枠２ａを容易に乗り越えることができる。When traveling on the ground (including slopes where no frame is installed), the position adjusting hydraulic cylinder 26 is contracted so that the wheel removal preventing roller 14 is positioned above the lower portion of the tire 6, The running of the slope working vehicle 1 is not disturbed.
In addition, since the tire 6 has a diameter dimension that is twice or more the height dimension of the method frame 2a, it can easily get over the method frame 2a.

法枠２ａ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、左右のウインチ７のワイヤー２７の先端部を法面上部の主アンカー２８に固定する。主アンカー２８にワイヤー２７を固定したらウインチ７を巻き上げて前進させる。なお、４輪のタイヤ７がそれぞれ法枠２ａの上に乗るように、伸縮機構４を左右方向に伸縮させ、タイヤ６の左右間隔と法枠２の幅が合うように伸縮機構４を調整するとよい。   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 27 of the left and right winches 7 are fixed to the main anchor 28 at the upper part of the slope. . When the wire 27 is fixed to the main anchor 28, the winch 7 is wound up and advanced. When the telescopic mechanism 4 is stretched in the left-right direction so that the four-wheel tires 7 are respectively on the frame 2a, and the telescopic mechanism 4 is adjusted so that the left-right distance of the tire 6 matches the width of the frame 2 Good.

また、前記支持具９の支持具用油圧シリンダー８の作動杆８ａを伸長し、支持具９により作業車本体３を支持した状態（タイヤ６が浮いた状態）にし、この状態で伸縮機構４の一方のタイヤ取付部１６（例えば左側のタイヤ取付部）を伸長し、前記支持具９の支持具用油圧シリンダー８の作動杆８ａを縮めてタイヤ６を接地し、前記一方のタイヤ取付部１６を縮めるとともに他方のタイヤ取付部１６（例えば右側のタイヤ取付部）を伸長する。その状態で再び支持具９により作業車本体３を支持した状態（タイヤ６が浮いた状態）にし、他方のタイヤ取付部１６を縮めた後にタイヤ６を接地すれば、支持具９及び伸縮機構４により作業車本体３自体を左右方向に移動させることもできる。   Further, the operating rod 8a of the support hydraulic cylinder 8 of the support 9 is extended so that the work vehicle body 3 is supported by the support 9 (the tire 6 is in a floating state). One tire mounting portion 16 (for example, the left tire mounting portion) is extended, the operating rod 8a of the support hydraulic cylinder 8 of the support 9 is contracted to ground the tire 6, and the one tire mounting portion 16 is While shrinking, the other tire attachment part 16 (for example, the right tire attachment part) is extended. If the work vehicle body 3 is again supported by the support 9 in this state (the tire 6 is in a floating state), and the tire 6 is grounded after the other tire mounting portion 16 is contracted, the support 9 and the telescopic mechanism 4 Thus, the work vehicle main body 3 itself can be moved in the left-right direction.

４輪のタイヤ６がそれぞれ法枠２ａの上に乗りあげた後、位置調整用油圧シリンダー２６を伸長し脱輪防止ローラー１４をタイヤ６下部の法枠側壁に当接させる。この時、伸縮機構４を左右方向に伸縮させて脱輪防止ローラー１４の横方向の位置を微調整してもよい。   After each of the four tires 6 rides on the method frame 2 a, the position adjusting hydraulic cylinder 26 is extended so that the derailment prevention roller 14 is brought into contact with the method frame side wall under the tire 6. At this time, the expansion / contraction mechanism 4 may be expanded / contracted in the left / right direction to finely adjust the lateral position of the wheel removal preventing roller 14.

なお、法面作業車１は、支持具９が設けられている支持具用油圧シリンダー８を伸長させて、支持具９を法面２又は法枠２ａに接地して作業車本体３を支持した状態で、伸縮機構４を左右方向に伸縮させることにより、法枠２ａを左右に移動することもできる。
作業位置に法面作業車１が到着したら、削孔装置１２の支持台用油圧シリンダー２０、回動機構２２を作動させ、スイングブーム２３を回動させロックボルト挿入孔やグランドアンカー挿入孔を形成することができる位置にセットし、油圧ドリフター２５を駆動させて、ロックボルト挿入孔やグランドアンカー挿入孔を形成する。The slope work vehicle 1 supports the work vehicle body 3 by extending the support tool hydraulic cylinder 8 provided with the support tool 9 and grounding the support tool 9 to the slope 2 or the slope frame 2a. In this state, the elastic frame 4a can be moved left and right by extending and retracting the expansion and contraction mechanism 4 in the left and right direction.
When the slope work vehicle 1 arrives at the work position, the support base hydraulic cylinder 20 and the turning mechanism 22 of the hole drilling device 12 are operated, and the swing boom 23 is turned to form a lock bolt insertion hole and a ground anchor insertion hole.
