Description
本発明は、穿孔対象物に複数の孔を連続させた溝を形成するための先行孔への案内ロッド挿入作業の容易な穿孔装置に関する。 The present invention relates to a drilling device that facilitates insertion of a guide rod into a preceding hole for forming a groove in which a plurality of holes are continuously formed in a drilling target.
穿孔対象物としての例えば地山の岩盤に複数の孔を一定間隔隔てて連続させて形成する穿孔方法及びこの方法に用いる穿孔装置が知られている。この穿孔装置を図５に基づいて説明する。尚、図５の右側を「前」、左側を「後」と定義して説明する。穿孔装置１Ｐは、図外の操縦機のアームに連結されるガイドセルと呼ばれる基台１７Ｐと、基台１７Ｐに前後移動可能に設けられた削岩機２Ｐと、基台１７Ｐの前部に設けられた支持部１３Ｐと、支持部１３Ｐに連結されて前方に突出する案内ロッド１１Ｐと、削岩機２Ｐのドリル部３Ｐが案内ロッド１１Ｐの軸線に沿った方向にスライド可能となるようドリル部３Ｐの穿孔ロッド１４Ｐと案内ロッド１１Ｐとを互いに連結するリニアガイドと呼ばれる連結部材１５Ｐとを備える。削岩機２Ｐは、ドリル部３Ｐとドリル部３Ｐを駆動する図外の駆動装置とを備える。ドリル部３Ｐは、駆動装置により回転する回転軸１４ｄと回転軸１４ｄの前端に回転軸１４ｄと一緒に回転するように連結された穿孔ロッド１４Ｐとを備える。穿孔ロッド１４Ｐは、前端に穿孔ビットと呼ばれる切削部１４ｂを備える。案内ロッド１１Ｐは、後端部が支持部１３Ｐに連結固定され前端には先鋭なキャップ１２Ｐを備える。連結部材１５Ｐは、穿孔ロッド１４Ｐに連結された連結部１５ｂと案内ロッド１１Ｐの筒内をスライドするスライド部材１５ａとこれら連結部１５ｂとスライド部材１５ａとを連結する連結板１５ｃとで構成される。連結部材１５Ｐの連結板１５cの前端には、岩盤破砕用の硬質部材であるチップと呼ばれる切削刃部１６Ｐが設けられる。支持部１３Ｐの前面には規制部材１８Ｐが取付けられる。ドリル部３Ｐは支持部１３Ｐに形成された孔１９Ｐを貫通し、前後に移動可能である。基台１７Ｐの前端に連結される支持部１３Ｐは、基台１７Ｐの延長方向に対して上方に垂直に延長する鋼板のような剛体よりなる。
穿孔装置１Ｐによる穿孔作業を説明する。まず、削岩機２Ｐの駆動装置を駆動してドリル部３Ｐの前端の切削部１４ｂで岩盤を削って図外の先行孔を形成する。次に支持部１３Ｐに案内ロッド１１Ｐを取り付ける。そして、操縦機によってアームを制御して案内ロッド１１Ｐを先行孔内に挿入する。その後、削岩機２Ｐの駆動装置を駆動してドリル部３Ｐの切削部１４ｂと連結部材１５Ｐの切削部１６Ｐとで岩盤を削ることで、先行孔と一定の間隔を隔てた図外の後行孔が切削部１４ｂにより形成され、先行孔と後行孔とを一定の間隔で連結する図外の連結孔が切削部１６Ｐにより形成される。以後、孔を穿孔する際に当該孔を穿孔する前に形成した孔を先行孔として利用していって複数の孔を形成していくことで、孔の延長方向と直交する方向において複数の孔が数珠繋ぎのように連続する連続削孔と呼ばれる孔溝、すなわち、複数の孔の外周の一部同士が連結孔により互いに連結された溝を形成できる。
A drilling operation by the punching apparatus 1P will be described. First, the driving device of the rock drill 2P is driven and the rock is cut by the cutting portion 14b at the front end of the drill portion 3P to form a leading hole (not shown). Next, the guide rod 11P is attached to the support portion 13P. Then, the guide rod 11P is inserted into the preceding hole by controlling the arm with the pilot. After that, the driving device of the rock drill 2P is driven to cut the rock with the cutting part 14b of the drill part 3P and the cutting part 16P of the connecting member 15P, so A hole is formed by the cutting part 14b, and a connecting hole (not shown) that connects the preceding hole and the succeeding hole at a constant interval is formed by the cutting part 16P. Thereafter, when the hole is drilled, the hole formed before the hole is drilled is used as the preceding hole, and a plurality of holes are formed in a direction orthogonal to the extension direction of the hole. Can be formed as a continuous groove that is continuous like a daisy chain, that is, a groove in which a part of the outer periphery of a plurality of holes is connected to each other by a connecting hole.
上述した穿孔装置１Ｐの案内ロッド１１Ｐを先行孔内に挿入する作業において、岩盤に形成された先行孔の孔の進行（延長）方向とアームにより前進する案内ロッド１１Ｐの進行方向とが一致していない場合は、操縦機のアームを操縦して案内ロッド１１Ｐの前端を先行孔に挿入した後に案内ロッド１１Ｐを先行孔内に押し込もうとしても案内ロッド１１Ｐの前端が先行孔の内壁に衝突してそれ以上前に進まなくなり、案内ロッド１１Ｐを先行孔内に挿入することができない。よって、事前に、アームを操縦して案内ロッド１１Ｐの位置や案内ロッド１１Ｐの傾き角度を微調整することによって案内ロッド１１Ｐの進行方向を先行孔の孔の進行方向に一致させてから案内ロッド１１Ｐを先行孔内に挿入する必要がある。案内ロッド１１Ｐの進行方向を、挿入目標とする先行孔の孔の進行方向に一致させるためには、操縦者が、案内ロッド１１Ｐを挿入する目標である先行孔の孔尻を確認して、案内ロッド１１Ｐが先行孔の孔尻の方向に真直ぐに延長するように案内ロッド１１Ｐの傾き角度を調整しなければならない。
しかしながら、そもそも操縦機の操縦席から穿孔対象物までは遠いことが多く、操縦席に着座し操縦者が、案内ロッドの前端の位置を先行孔の位置に合わせる作業自体も容易ではなく、案内ロッド１１Ｐを挿入する目標である先行孔の孔尻を確認することも容易ではない。よって、案内ロッド１１Ｐが先行孔の孔尻の方向に真直ぐに延長するように案内ロッド１１Ｐの傾き角度を調整して案内ロッド１１Ｐの進行方向を先行孔の孔の進行方向に一致させることは困難であり、従って、案内ロッド１１Ｐを先行孔内に挿入する作業が困難であるという課題があった。
In the operation of inserting the guide rod 11P of the drilling device 1P described above into the preceding hole, the traveling (extension) direction of the hole in the preceding hole formed in the bedrock coincides with the traveling direction of the guide rod 11P advanced by the arm. If there is not, the front end of the guide rod 11P collides with the inner wall of the preceding hole even if an attempt is made to push the guide rod 11P into the preceding hole after manipulating the arm of the pilot and inserting the front end of the guiding rod 11P into the preceding hole. The guide rod 11P cannot be inserted into the preceding hole. Therefore, by manipulating the arm in advance to finely adjust the position of the guide rod 11P and the inclination angle of the guide rod 11P, the direction of travel of the guide rod 11P is made to coincide with the direction of travel of the preceding hole, and then the guide rod 11P Must be inserted into the leading hole. In order to make the traveling direction of the guide rod 11P coincide with the traveling direction of the hole of the preceding hole targeted for insertion, the operator confirms the hole bottom of the preceding hole that is the target for inserting the guide rod 11P, and guides The inclination angle of the guide rod 11P must be adjusted so that the rod 11P extends straight in the direction of the hole bottom of the preceding hole.
However, in the first place, it is often far from the cockpit of the pilot machine to the object to be drilled, and it is not easy for the operator to sit on the cockpit and adjust the position of the front end of the guide rod to the position of the leading hole. It is not easy to confirm the hole bottom of the preceding hole, which is the target for inserting 11P. Therefore, it is difficult to adjust the inclination angle of the guide rod 11P so that the guide rod 11P extends straight in the direction of the hole bottom of the preceding hole so that the traveling direction of the guide rod 11P matches the traveling direction of the hole of the preceding hole. Therefore, there is a problem that it is difficult to insert the guide rod 11P into the preceding hole.

図２を参照し、本形態の穿孔装置１を説明する。穿孔装置１は、操縦機２と基台４と削岩機５と案内ロッド６と支持部７とリニアガイドと呼ばれる連結部材８と撮像照明ユニット６０とを備える。基台４は操縦機２のアーム２ａに取付けられる。操縦機２は、例えばドリルジャンボウと呼ばれる機械である。基台４は、上面にガイドレール４ａを備える。ガイドレール４ａには、削岩機５の駆動装置９が前後方向に移動可能に搭載される。削岩機５は、駆動装置９とドリル部３とを備える。ドリル部３は、回転軸１０と穿孔ロッド１１とを備える。駆動装置９は、図外のモータによる回転駆動源及び油圧機構による前後駆動源を備える。駆動装置９の回転駆動源には、回転軸１０が回転可能に連結される。穿孔ロッド１１は、回転軸１０の前端に連結されて回転軸１０の回転力で回転する。穿孔ロッド１１は前端に穿孔ビットと呼ばれる切削部４１を備える。切削部４１の前面には切削刃４２を備える。駆動装置９に連結された図外の前後移動機構を操縦機２で操縦して駆動装置９の筐体を前後に移動させることで削岩機５の前後位置を調整できる。削岩機５による穿孔時には、駆動装置９を駆動させて回転駆動源により回転軸を回転させるとともに前後駆動源により駆動装置９の筐体を前後に振動させて穿孔ロッド１１に回転力と打撃力とを加えることで穿孔ロッド１１の切削部４１が地山の岩盤などの穿孔対象物を切削するので穿孔対象物に孔を形成できる。連結部材８は、穿孔ロッド１１と案内ロッド６とを互いに連結するとともに、穿孔ロッド１１と案内ロッド６との間の距離を一定に保ちながら穿孔ロッド１１を案内ロッド６の軸線Ｇに沿う方向に移動可能とするものである。支持部７は、基台側支持部１３と案内ロッド取付体１４と連結装置１５とを備え、基台４の前端に連結固定された鋼板のような板よりなる基台側支持部１３と基台側支持部１３の上方に配置された鋼板のような板よりなる案内ロッド取付体１４とが左右２つの連結装置１５；１５により互いに連結されて構成される。削岩機５のドリル部３は、案内ロッド取付体１４に形成された孔１６を前後に貫通し前後に移動可能である。案内ロッド６は、案内ロッド６の後部が案内ロッド取付体１４に連結固定されて案内ロッド取付体１４の前方に延長する。基台側支持部１３の前面には規制部材１８が取付けられる。基台４と操縦機２のアーム２ａとが互いに連結され、操縦機２のアーム２ａは、図外の油圧機構により駆動する。よって、操縦者が操縦機２を操縦してアーム２ａの動きを制御することで、案内ロッド６の位置や角度を調整し、案内ロッド６を先行孔内に挿入する際の案内ロッド６の位置決め作業を行う。 With reference to FIG. 2, the punching apparatus 1 of this form is demonstrated.

The piercing rod 11 includes a cutting portion 41 called a piercing bit at the front end. A cutting blade 42 is provided on the front surface of the cutting portion 41. The front-rear position of the rock drill 5 can be adjusted by manipulating the forward / backward moving mechanism (not shown) connected to the drive device 9 with the controller 2 and moving the housing of the drive device 9 back and forth. At the time of drilling by the rock drill 5, the driving device 9 is driven to rotate the rotation shaft by the rotation driving source, and the casing of the driving device 9 is vibrated back and forth by the front and rear driving source to cause the drilling rod 11 to rotate and hit. Since the cutting part 41 of the piercing rod 11 cuts the piercing object such as a natural rock, the hole can be formed in the piercing object. The connecting member 8 connects the piercing rod 11 and the guide rod 6 to each other, and keeps the piercing rod 11 in a direction along the axis G of the guide rod 6 while keeping the distance between the piercing rod 11 and the guide rod 6 constant.

That is, the upper end of the coil spring 20 is connected to the upper mounting portion 21, and the lower end of the coil spring 20 is connected to the lower mounting portion 22. The upper attachment portion 21 of the coupling device 15 is fixed to the guide rod attachment body 14 by a fixture 23, and the lower attachment portion 22 is fixed to the base side support portion 13 by the fixture 23. The fixing tool 23 is formed by forming a rod such as a steel rod into a U shape and forming screw portions (not shown) at both ends. A pair of left and right holes 24; 24 are formed on the left and right sides of the base side support portion 13 and the guide rod mounting body 14 so as to penetrate the U-shaped ends of the fixture 23 through the front and rear of the plate.

The support part 7 can be easily formed.
案内ロッド取付体１４の中央には、上部開放で板の前後に貫通する案内ロッド６の位置決め設置用の孔２５が形成される。孔２５の下方には、削岩機５のドリル部３を前後に移動可能に貫通させる孔１６が形成される。孔２５と孔１６とは、連絡孔２６により上下に連続している。案内ロッド６は、円筒状パイプ２８の前端に円錐形状の先鋭なキャップ部材２９が着脱可能に取り付けられたものである。案内ロッド６の前端にキャップ部材２９を備えることで、案内ロッド６の前端の先行孔への挿入を容易にしている。円筒状パイプ２８は、円筒パイプの外周において円筒パイプの軸線に沿う方向に一直線状の開口溝３０が形成されたものである。案内ロッド６の後部が取付板３１に取り付けられる。取付板３１の中央には、下部開放で板の前後に貫通する嵌合孔３２が形成される。案内ロッド６の後部が、取付板３１の嵌合孔３２に嵌め込まれて、案内ロッド６の開口溝３０と嵌合孔３２の開口部３３との位置が合わされた状態で、案内ロッド６の後端部の周囲と取付板３１の後面とが溶接のような連結手段で連結されることで、案内ロッド６と取付板３１とが互いに連結される。案内ロッド６が取り付けられた取付板３１は、案内ロッド取付体１４に連結固定される。つまり、案内ロッド６の後部を設置用の孔２５内に位置させ、案内ロッド取付体１４の後面に取付板３１の前面を当てて開口部３３と連絡孔２６との位置を前後で一致させて案内ロッド取付体１４と取付板３１とをボルト３４，ナット３５のような固定具３６（図２参照）で連結することで、案内ロッド６が案内ロッド取付体１４に着脱可能に取り付けられる。設置用の孔２５を上部開放としたため、案内ロッド６を孔２５の上方から取り付けることができ、案内ロッド取付体１４に対する案内ロッド６の着脱作業を容易とできる。 In the center of the guide rod mounting body 14, a hole 25 for positioning and installing the guide rod 6 that is open at the top and penetrates the front and rear of the plate is formed. A hole 16 is formed below the hole 25 so as to penetrate the drill portion 3 of the rock drill 5 so as to be movable back and forth. The hole 25 and the hole 16 are vertically continuous by the communication hole 26. The guide rod 6 is configured such that a conical sharp cap member 29 is detachably attached to a front end of a cylindrical pipe 28. By providing the cap member 29 at the front end of the guide rod 6, the front end of the guide rod 6 can be easily inserted into the preceding hole.

The imaging illumination unit 60 is provided immediately behind the guide rod 6 on the upper surface 59 a of the unit installation member 59 fixedly installed on the base 4. The imaging illumination unit 60 includes an imaging device 61 such as a video camera that images the front of the guide rod 6 connected to the support portion 7 and a light source 62 that illuminates the front of the guide rod 6. As shown in FIG. 1B, when viewed from the front, the imaging illumination unit 60 has a lens 63 of the imaging device 61 disposed in the center and surrounds the outer periphery of the lens 63 of the imaging device 61 on the front surface. A cylindrical front protrusion 64 is provided. A plurality of light sources 62 are installed on the front surface of the front protrusion 64 so as to face forward. For example, twelve light sources 62 are arranged at 30 ° intervals with respect to the circular center of the cylinder of the front protrusion 64. The light source 62 is preferably a laser light source that emits and emits laser light such as a semiconductor laser. The imaging illumination unit 60 may be installed immediately after the guide rod 6 and at a position where the guide rod 6 and the front of the guide rod 6 can be imaged and illuminated. As shown in FIG. 1C, a display device 66 that displays a video signal from the imaging device 61 is provided on the console 70 of the cockpit 65 of the controller 2. Reference numeral 67 denotes a power cable for supplying power from a power supply unit (not shown) to the imaging illumination unit, and 68 is a signal cable for transmitting a video signal from the imaging device 61 to the display device 66.
穿孔装置１による穿孔作業を説明する。最初の先行孔を形成する際には、案内ロッド６と連結部材８は取り外されている。つまり、穿孔ロッド１１の後軸４６の小径軸部４８に連結部材８が取付けられていない状態で小径軸部４８の前部と前軸４５の後部とが連結される。この形態でドリル部３の穿孔ロッド１１を案内ロッド取付体１４の孔１６を経由させて前方に進め、駆動装置９でドリル部３を駆動して切削部４１で岩盤を切削して先行孔を形成する。 A drilling operation by the punching apparatus 1 will be described. When the first leading hole is formed, the guide rod 6 and the connecting member 8 are removed. That is, the front portion of the small diameter shaft portion 48 and the rear portion of the front shaft 45 are connected in a state where the connecting member 8 is not attached to the small diameter shaft portion 48 of the rear shaft 46 of the drilling rod 11. In this configuration, the drilling rod 11 of the drill unit 3 is advanced forward through the hole 16 of the guide rod mounting body 14, the drill unit 3 is driven by the driving device 9, and the rock is cut by the cutting unit 41 to form the preceding hole. Form.
先行孔を形成した後に、ドリル部３を案内ロッド取付体１４より後方に移動してから、上述したように案内ロッド６を案内ロッド取付体１４に取付ける。そして、穿孔ロッド１１の後軸４６から前軸４５を取り外し、後軸４６の小径軸部４８を連結部材８の筒体５０の孔５２の一端から他端に挿入して、他端に突出した小径軸部４８の前部と前軸４５の後部とを連結する。これにより、連結部材８の筒体５０が小径軸部４８に保持され、かつ、前軸４５の後端と大径軸部４７の前端とで筒体５０の前後移動が規制されて、連結部材８が小径軸部４８により前軸４５の後端と大径軸部４７の前端との間に保持される。小径軸部４８の前部と前軸４５の後部との着脱可能な連結手段としては、小径軸部４８の前部に形成された雄ねじ部４９と前軸４５の後部に形成されたねじ孔４９ａとのねじ結合や、前軸４５の後部に形成された図外の嵌合孔に小径軸部４８の前部を嵌め込んで嵌合孔の外周面に形成された図外のねじ孔にねじをねじ込んで小径軸部４８の前部を締結することによるねじ結合などである。以上のように、小径軸部４８を連結部材８の筒体５０の孔５２に通して前軸４５の後部に連結するだけで穿孔ロッド１１に連結部材８を取り付けることでき、穿孔ロッド１１に対する連結部材８の着脱作業を容易とできる。そして、ドリル部３を前進させ、穿孔ロッド１１の連結部材保持体４０に保持された連結部材８のスライド体５１を、取付板３１の後方から案内ロッド６の筒孔により形成されたスライドレール５５内に挿入することで、案内ロッド６に連結部材８を取り付けることができ、案内ロッド６に対する連結部材８の着脱作業を容易とできる。取付板３１の開口部３３と案内ロッド取付体１４の連絡孔２６と案内ロッド６の開口溝３０の横幅は、連結部材８の連結板２７の板幅より長く形成され、連結板２７が通過できる。また、連結部材８の筒体５０は、穿孔ロッド１１が回転しても回転しない状態に保持される。したがって、ドリル部３を孔１６を経由させて前方に進行させると、連結部材８のスライド体５１がスライドレール５５内を前方に進みドリル部が案内ロッド６に沿って前方に進む。これにより、ドリル部３は、案内ロッド６に対して一定の距離を保ちながら、案内ロッド６の軸線Ｇに沿った方向に移動可能となる。すなわち、連結部材８によりドリル部３が案内ロッド６と一定の距離を維持しながら案内ロッド６に沿って前後に移動可能となる。 After the leading hole is formed, the drill portion 3 is moved rearward from the guide rod attachment body 14, and then the guide rod 6 is attached to the guide rod attachment body 14 as described above. Then, the front shaft 45 is removed from the rear shaft 46 of the perforated rod 11, and the small-diameter shaft portion 48 of the rear shaft 46 is inserted into one end of the hole 52 of the cylindrical body 50 of the connecting member 8 and protrudes to the other end. The front part of the small-diameter shaft part 48 and the rear part of the front shaft 45 are connected. Thereby, the cylindrical body 50 of the connecting member 8 is held by the small-diameter shaft portion 48, and the longitudinal movement of the cylindrical body 50 is restricted by the rear end of the front shaft 45 and the front end of the large-diameter shaft portion 47. 8 is held between the rear end of the front shaft 45 and the front end of the large diameter shaft portion 47 by the small diameter shaft portion 48. As a detachable connecting means between the front part of the small diameter shaft part 48 and the rear part of the front shaft 45, a male screw part 49 formed at the front part of the small diameter shaft part 48 and a screw hole 49a formed at the rear part of the front shaft 45 are provided. And the front portion of the small-diameter shaft portion 48 is fitted into a non-illustrated fitting hole formed in the rear portion of the front shaft 45 and the screw hole is formed in the non-illustrated screw hole formed in the outer peripheral surface of the fitting hole. And screw connection by fastening the front portion of the small-diameter shaft portion 48. As described above, the connecting member 8 can be attached to the piercing rod 11 simply by passing the small-diameter shaft portion 48 through the hole 52 of the cylindrical body 50 of the connecting member 8 to the rear portion of the front shaft 45. The attachment / detachment work of the member 8 can be facilitated. Then, the drill portion 3 is advanced, and the slide body 51 of the connecting member 8 held by the connecting member holding body 40 of the perforating rod 11 is moved from the rear of the mounting plate 31 to the slide rail 55 formed by the cylindrical hole of the guide rod 6. By inserting into the guide rod 6, the connecting member 8 can be attached to the guide rod 6, and the connecting member 8 can be easily attached to and detached from the guide rod 6. The lateral width of the opening 33 of the mounting plate 31, the connecting hole 26 of the guide rod mounting body 14, and the opening groove 30 of the guide rod 6 is formed longer than the width of the connecting plate 27 of the connecting member 8, and the connecting plate 27 can pass through. . Further, the cylindrical body 50 of the connecting member 8 is held in a state in which it does not rotate even if the drilling rod 11 rotates. Therefore, when the drill portion 3 is advanced forward through the hole 16, the slide body 51 of the connecting member 8 advances forward in the slide rail 55, and the drill portion advances forward along the guide rod 6. As a result, the drill portion 3 can move in the direction along the axis G of the guide rod 6 while maintaining a certain distance from the guide rod 6. That is, the connecting member 8 allows the drill portion 3 to move back and forth along the guide rod 6 while maintaining a certain distance from the guide rod 6.
上述のように、連結部材８により案内ロッド６に対してドリル部３を前後に移動可能に取付けた後に、操縦機２の操縦者が、アーム２ａの動きを制御して案内ロッド６の位置を調整し、案内ロッド６を先行孔内に挿入する作業を行う
本形態の穿孔装置１によれば、操縦機２の操縦室６５の操縦者が、表示装置６６に映し出される撮像装置６１の前方の映像を見ながらアーム２ａを操縦して案内ロッド６の前端の位置を先行孔の位置に合わせることができるので、この位置合わせ作業が容易となる。この際、複数の光源６２により案内ロッド６と案内ロッド６の前方を照明するので、位置合わせ作業がより容易となる。そして、図１（ｃ）のように、表示装置６６の映像を見て先行孔５８の孔尻５８ｅを確認することによって、先行孔５８の孔の傾き角度と案内ロッド６の傾き角度との一致を確認できることから、図４に示すように、案内ロッド１１Ｐの進行方向を岩盤５７に形成した先行孔５８の孔の進行方向に一致させることが容易となり、案内ロッド１１Ｐを先行孔５８内に挿入する作業が容易となる。この際、複数の光源６２により案内ロッド６と案内ロッド６の前方を照明するので、先行孔５８の孔尻５８ｅを明るく照らすことができ、孔尻５８ｅの確認作業が容易となる。また、光源６２としてレーザ光源を用いれば、レーザ光の直進性により孔尻５８ｅを点状態に照明でき、案内ロッド６を入れる位置を光の点状態で示せる。これにより、作業者が案内ロッド６を入れる目標となる孔尻５８ｅの確認作業を容易にでき、作業のスムーズ化に貢献できる。
As described above, after the drill member 3 is attached to the guide rod 6 so as to be movable back and forth by the connecting member 8, the operator of the pilot 2 controls the movement of the arm 2a to change the position of the guide rod 6. According to the punching device 1 of the present embodiment, the operator who adjusts and inserts the guide rod 6 into the preceding hole is arranged. The operator of the cockpit 65 of the pilot 2 is in front of the imaging device 61 projected on the display device 66. Since the position of the front end of the guide rod 6 can be adjusted to the position of the preceding hole by manipulating the arm 2a while viewing the image, this alignment operation is facilitated. At this time, since the guide rod 6 and the front of the guide rod 6 are illuminated by the plurality of light sources 62, the alignment operation becomes easier. Then, as shown in FIG. 1C, by confirming the hole bottom 58e of the preceding hole 58 by viewing the image of the display device 66, the inclination angle of the hole of the preceding hole 58 matches the inclination angle of the guide rod 6. 4, it becomes easy to make the traveling direction of the guide rod 11P coincide with the traveling direction of the preceding hole 58 formed in the bedrock 57, and the guide rod 11P is inserted into the preceding hole 58 as shown in FIG. Work becomes easier. At this time, since the plurality of light sources 62 illuminate the guide rod 6 and the front of the guide rod 6, the hole bottom 58e of the preceding hole 58 can be illuminated brightly, and the confirmation operation of the hole bottom 58e becomes easy. Further, if a laser light source is used as the light source 62, the hole bottom 58e can be illuminated in a dot state by the straightness of the laser beam, and the position where the guide rod 6 is inserted can be indicated in the light dot state. As a result, the operator can easily confirm the hole bottom 58e, which is the target for inserting the guide rod 6, and contribute to smoothing the operation.
さらに、本形態の穿孔装置１によれば、連結装置１５のコイルばね２０の弾性により案内ロッド６が可動な状態に維持されているので、案内ロッド６と先行孔との衝突によって案内ロッド６に加わる力により、案内ロッド６が案内ロッド６の進行方向を変えるように動いたり、案内ロッド６に沿った方向と直交する方向に動くことが可能である。従って、例えば、図４の地山の岩盤５７に形成された先行孔５８の進行方向とアーム２ａにより前進する案内ロッド６の進行方向とが一致していない状態で案内ロッド６の前端を先行孔５８内に挿入し、アーム２ａを操縦して案内ロッド６を前方に進めたとしても、先行孔５８と案内ロッド６との衝突によって案内ロッド６に加わる力により、案内ロッド取付体１４が案内ロッド６からの力で動き、案内ロッド６が進行方向を変えながら先行孔５８内を前進するので、案内ロッド６の先行孔５８内への挿入作業が容易となる。 Furthermore, according to the punching device 1 of the present embodiment, the guide rod 6 is maintained in a movable state by the elasticity of the coil spring 20 of the coupling device 15, so that the guide rod 6 is brought into contact with the guide rod 6 by the collision between the guide rod 6 and the preceding hole. By the applied force, the guide rod 6 can move so as to change the traveling direction of the guide rod 6 or can move in a direction perpendicular to the direction along the guide rod 6. Therefore, for example, the front end of the guide rod 6 is formed in the leading hole in a state where the traveling direction of the leading hole 58 formed in the rock 57 of the natural ground in FIG. 4 does not coincide with the traveling direction of the guiding rod 6 advanced by the arm 2a. 58, even if the guide rod 6 is moved forward by maneuvering the arm 2a, the guide rod mounting body 14 is guided by the force applied to the guide rod 6 due to the collision between the leading hole 58 and the guide rod 6. 6, the guide rod 6 moves forward in the preceding hole 58 while changing the traveling direction, so that the guide rod 6 can be easily inserted into the preceding hole 58.
案内ロッド６を先行孔５８内に挿入した後、規制部材１８の前端を図４の岩盤に突付けてから、ドリル部３の前端の切削部４１を岩盤５７まで移動した後に削岩機５を駆動することにより、ドリル部３を案内ロッド６の軸線Ｇに沿って前進させることで図外の後行孔を形成する。すなわち、先行孔５８の下方の岩盤５７を切削して先行孔５８の延長する方向と直交する方向において先行孔５８と一定の間隔を隔てて連続する後行孔を穿孔する。この際、先行孔５８と後行孔との間は連結部材８の切削部５３で削岩されることによって、先行孔５８と後行孔との間を繋ぐ図外の連結孔が形成される。すなわち、岩盤５７に先行孔５８と孔の外周の一部同士を連結孔によって連続させた後行孔を形成できる。以後、孔を穿孔する際に当該孔を穿孔する前に形成した孔を先行孔として利用していって複数の孔を形成していくことで、孔の延長する方向と直交する方向において複数の孔を数珠繋ぎのように連続させた連続削孔と呼ばれる孔溝、すなわち、複数の孔の外周の一部同士が連結孔により互いに連結された溝を形成でき、この溝を岩盤５７の破砕に利用することで、例えば、横坑を掘削する。 After the guide rod 6 is inserted into the leading hole 58, the front end of the restricting member 18 is abutted against the rock in FIG. 4 and then the cutting portion 41 at the front end of the drill portion 3 is moved to the rock 57, and then the rock drill 5 is moved. By driving, the drill portion 3 is advanced along the axis G of the guide rod 6 to form a trailing hole (not shown). That is, the rock 57 under the leading hole 58 is cut to drill a subsequent hole that is continuous with the leading hole 58 at a certain interval in a direction orthogonal to the direction in which the leading hole 58 extends. At this time, the leading hole 58 and the following hole are drilled by the cutting portion 53 of the connecting member 8 to form a connecting hole (not shown) that connects the leading hole 58 and the following hole. . That is, it is possible to form a trailing hole in the bedrock 57 in which the leading hole 58 and a part of the outer periphery of the hole are made continuous by the connecting hole. Thereafter, when the hole is drilled, the hole formed before the hole is drilled is used as the preceding hole, and a plurality of holes are formed. A hole groove called continuous drilling in which holes are connected like a daisy chain, that is, a groove in which a part of the outer periphery of a plurality of holes is connected to each other by a connection hole can be formed, and this groove can be used for crushing the bedrock 57 For example, a horizontal shaft is excavated.
上記のように、案内ロッド６とドリル部３の穿孔ロッド１１とを連結部材８により連結した構成とすれば、ドリル部３の直進性を向上できる。しかしながら、案内ロッド６とドリル部３の穿孔ロッド１１とを連結せずに、ドリル部３を案内ロッド６の軸線Ｇに沿った方向に前後に移動させる構成において、案内ロッド６及び案内ロッド６の前方を撮像する撮像照明ユニット６０と、撮像照明ユニット６０からの映像信号を映す表示装置６６とを備えた穿孔装置１であっても良い。
上記では、基台側支持部１３と案内ロッド取付体１４とを互いに連結する連結装置１５の弾性部材としてコイルばね２０を用いた例を示したが、連結装置１５の弾性部材として板ばねを用いても良い。連結装置１５の弾性部材としてコイルばね２０と板ばねとを併用しても良い。
穿孔装置１の支持部としては、図５で示した支持部１３Ｐと同じ構成のものを用いてもよい。
撮像装置６１や光源６２は支持部７や支持部１３Ｐの上部に設置しても良く、この場合でも、案内ロッド６及び案内ロッド６の前方を撮像したり照明したりできるので、本発明の効果が得られる。電球のようなコヒーレントでない光を発生する光源とコヒーレントなレーザ光を発生するレーザ光源とを併用して光源６２を構成しても良い。光源６２の種類や数は特に限定されないし、作業場の光量が十分であれば、必ずしも設けなくとも良い。

However, in the configuration in which the drill portion 3 is moved back and forth in the direction along the axis G of the guide rod 6 without connecting the guide rod 6 and the drill rod 11 of the drill portion 3, the guide rod 6 and the guide rod 6 The perforation apparatus 1 may include the imaging illumination unit 60 that captures the front and the display device 66 that displays the video signal from the imaging illumination unit 60.
