Description

本発明は、例えば建設現場でコンクリート等を切断するためのワイヤソー又はブレード切断装置及び切断方法に関する。   The present invention relates to a wire saw or blade cutting device and a cutting method for cutting concrete or the like at a construction site, for example.

従来、コンクリート・石材等の切断においてワイヤソーを用いる場合は、引き切りと押し切りとに分類される。後者は例えば、図６に示すように、駆動装置１１を駆動するモータを始動させて駆動輪１１ｂを回転させてワイヤーソーＷｓを高速走行させ、ワイヤソー押込装置２２のモータを始動させて車輪２２ａ１を徐々に回転させ、かつワイヤソーの余長調整装置１２の間隔調節手段１２ｃ１を始動させて間隔調節体１２ｃの長さを徐々に短縮して、押込装置２２を前進させて、押込装置２２の腕状支持体２２ｃ１，２２ｃ２の先端のガイドプーリー２２ｄ１，２２ｄ２を予め穿孔しておいた横孔Ｓｔ１内に挿入しながら、走行するワイヤーソーＷｓを構造物Ｓｔに前側から押し付け、構造物Ｓｔのコンクリート、鉄筋、鉄骨等を切断する。切断量に応じて、押込装置２２を前進させ、間隔調節体１２ｃの長さを短縮する。切断部には冷却水を供給し続けることにより、構造物Ｓｔを縦・横に押し切るように構成した押し切り切断方法が知られている。   Conventionally, when a wire saw is used for cutting concrete, stone, etc., it is classified into a draw and a push cut. In the latter case, for example, as shown in FIG. 6, the motor for driving the driving device 11 is started to rotate the driving wheel 11b to cause the wire saw Ws to travel at a high speed, and the motor for the wire saw pushing device 22 is started to start the wheel 22a1. The distance adjusting means 12c1 of the wire saw extra length adjusting device 12 is started gradually, the length of the interval adjusting body 12c is gradually shortened, the pushing device 22 is advanced, and the arm shape of the pushing device 22 is increased. While inserting the guide pulleys 22d1 and 22d2 at the tips of the supports 22c1 and 22c2 into the pre-drilled horizontal hole St1, the traveling wire saw Ws is pressed against the structure St from the front side, and the concrete and rebar of the structure St Cut the steel frame. In accordance with the cutting amount, the pushing device 22 is moved forward to shorten the length of the interval adjusting body 12c. There has been known a push-cut method that is configured to push the structure St vertically and horizontally by continuously supplying cooling water to the cutting part.

この場合、この方法ではワイヤソーの駆動装置１１と余長調整装置１２とを同時に同期駆動してワイヤソーＷｓの張力を一定とする特殊な制御方法が必要となり、全体の構成が複雑になってしまう。また余長調整装置１２の作用のために長めのワイヤソーが必要となり、余長調整装置１２内の多くのプーリ１２ｄ１，１２ｄ２…を介するため摩擦抵抗が多くなり、駆動モータの負荷が大きく、運転効率が悪い等の欠点を有する。 In this case, this method requires a special control method in which the wire saw driving device 11 and the extra length adjusting device 12 are simultaneously driven synchronously to keep the tension of the wire saw Ws constant, and the overall configuration becomes complicated. In addition, a longer wire saw is required for the operation of the extra length adjusting device 12, and since many pulleys 12d1, 12d2,... In the extra length adjusting device 12 are interposed, the frictional resistance increases, the load on the drive motor increases, and the operating efficiency increases. Has disadvantages such as bad.

解決しようとする問題点は、ワイヤソーによる押し切りにおいて、ワイヤソーの余長調整機能を簡素化して微小移動駆動を可能としかつ余長調節機能のためのワイヤソー通過部分のワイヤソー長さを短くでき、
押し切り時に被加工物付近のワイヤソーの案内プーリの支持体が撓んで被加工物に接してしまい大きな抵抗を作ることがある欠点を解消し、
更に同じ動力源でワイヤソー加工の押し切り・引き切りと共に回転ブレードによる切断を即座に切り替えて切断を可能とし、
更に自走機械のアーム先端位置に対し縦軸及び横軸に方向に自由に傾斜して切断装置のワイヤソーガイドシーブを自由に操作可能とし、又は切断装置に取り付けた回転ブレードを自由に操作可能とし、傾斜面切断が可能となる切断装置・切断方法を提案することを目的とする。 The problem to be solved is that, in the push-cutting by the wire saw, the wire saw extra length adjustment function is simplified to enable fine movement driving, and the wire saw passage portion for the extra length adjustment function can be shortened.
Eliminates the disadvantage that the support of the wire saw guide pulley in the vicinity of the work piece may be bent and contact the work piece when it is pushed, creating a large resistance.
Furthermore, with the same power source, cutting with a rotating blade can be immediately switched along with pressing and drawing of wire saw processing, enabling cutting.
Furthermore, the wire saw guide sheave of the cutting device can be freely operated by freely tilting in the direction of the vertical axis and the horizontal axis with respect to the arm tip position of the self-propelled machine, or the rotating blade attached to the cutting device can be freely operated. An object of the present invention is to propose a cutting device / cutting method capable of cutting an inclined surface.

本発明は、第１に、旋回上下左右前後可能ブームアームを備えた自走機械のアーム先端に押し切り用ワイヤソー装置を取り付けた切断装置である。 A first aspect of the present invention is a cutting device in which a wire saw device for push-off is attached to the tip of an arm of a self-propelled machine equipped with a boom arm capable of turning up, down, left and right.

第２に、押し切り用ワイヤソー装置はワイヤソーを案内する複数の支持棒とプーリと先端側ガイドプーリの付近に位置保持用ガイドローラを設け、支持棒が反対側ガイドプーリ側に撓むのを阻止する構成とした切断装置である。 Second, the push-cut wire saw device is provided with a plurality of support rods for guiding the wire saw, a pulley for positioning, and a guide roller for holding the position in the vicinity of the front end guide pulley, and the support rod is prevented from bending toward the opposite guide pulley side. The cutting device is configured.

第３に、ワイヤソー装置の自走機械との取り付けブラケットの平面板に軸を設け、同心の周囲位置に設けたボルトで下側ブラケットと締結して取り外し可能に一体化した切断装置である。 Thirdly, a cutting device in which a shaft is provided on a flat plate of a mounting bracket with a self-propelled machine of a wire saw device, and a lower bracket is fastened with a bolt provided in a concentric peripheral position so as to be detachably integrated.

第４に、自走機械のアーム先端にワイヤソー切断装置を取り付けて押し切りをする方法において、ワイヤソー切断装置の先端にワイヤソーを誘導するガイドプーリを設け、先に穿孔したコア孔にワイヤソーを巻き付けたガイドプーリを進入させ、ワイヤソーを移送させてワイヤソーに接する被切断物を切断し、かつワイヤソーが切断に伴って緊張状態が不足した場合に自走機械の位置を調節ワイヤソー切断装置全体の位置をずらしてワイヤソー緊張状態を保持するようにした切断方法である。 Fourth, in a method of attaching and cutting a wire saw cutting device to the tip of an arm of a self-running machine, a guide pulley for guiding the wire saw is provided at the tip of the wire saw cutting device, and the wire saw is wound around the core hole previously drilled. When the pulley is entered, the wire saw is moved to cut the workpiece that touches the wire saw, and the tension of the wire saw is insufficient due to cutting, the position of the self-propelled machine is adjusted and the position of the entire wire saw cutting device is shifted It is the cutting method which kept the wire saw tension state.

本発明は、第１に、旋回上下左右前後可能ブームアームを備えた自走機械のアーム先端に押し切り用ワイヤソー装置を取り付けた切断装置としたので、従来のようにワイヤソーを弛みを解消するための特別の機構を設ける必要がなくなり、切断装置の全体の構成を簡素化でき、廉価に提供できる効果を有する。   The present invention, firstly, is a cutting device in which a wire saw device for push-off is attached to the tip of an arm of a self-propelled machine equipped with a boom arm capable of turning up, down, left and right, so as to eliminate slack of the wire saw as in the prior art. There is no need to provide a special mechanism, the entire configuration of the cutting apparatus can be simplified, and the effect can be provided at low cost.

第２に、押し切り用ワイヤソー装置はワイヤソーを案内する複数の支持棒とプーリと先端側ガイドプーリの付近に位置保持用ガイドローラを設け、支持棒が反対側ガイドプーリ側に撓むのを阻止する構成としたので、押し切りに必要なコア孔が深くなればなるほど切断位置のガイドプーリの位置が不安定になり、切断時の引っ張り力でガイドプーリがコア孔に接して大きな摩擦抵抗を作る虞れがあるが、ガイドローラによって常に一定のガイドローラの位置を保持し得るため切断位置も設定時のまま最後まで切断することができる。 Second, the push-cut wire saw device is provided with a plurality of support rods for guiding the wire saw, a pulley for positioning, and a guide roller for holding the position in the vicinity of the front end guide pulley, and the support rod is prevented from bending toward the opposite guide pulley side. Since the core hole necessary for push-off becomes deeper, the position of the guide pulley at the cutting position becomes unstable, and the guide pulley may come into contact with the core hole due to the pulling force at the time of cutting to create a large frictional resistance. However, since the guide roller can always hold a fixed position of the guide roller, the cutting position can be cut to the end while being set.

第３に、ワイヤソー装置の自走機械との取り付けブラケットの平面板に軸を設け、同心の周囲位置に設けたボルトで下側ブラケットと締結して取り外し可能に一体化したので、被切断物の切断作業において残す箇所がある場合に従来のワイヤソー切断では斜めに切断できなかったが、水平面及び垂直面に対しある角度をもってワイヤソー切断面を設定しうることになり、自由な切断面を得ることが可能となり、石材の切り出し時に爾後の調整切りを省略することができる。 Thirdly, since a shaft is provided on the flat plate of the mounting bracket with the self-propelled machine of the wire saw device, and the lower bracket is fastened with a bolt provided in a concentric peripheral position, it is detachably integrated, so that When there is a place to leave in the cutting operation, the conventional wire saw cutting cannot be cut obliquely, but the wire saw cutting surface can be set at a certain angle with respect to the horizontal and vertical surfaces, and a free cutting surface can be obtained. This makes it possible to omit the adjustment cut after dredging when the stone is cut out.

第４に、自走機械のアーム先端にワイヤソー切断装置を取り付けて押し切りをする方法において、ワイヤソー切断装置の先端にワイヤソーを誘導するガイドプーリを設け、先に穿孔したコア孔にワイヤソーを巻き付けたガイドプーリを進入させ、ワイヤソーを移送させてワイヤソーに接する被切断物を切断し、かつワイヤソーが切断に伴って緊張状態が不足した場合に自走機械の位置を調節ワイヤソー切断装置全体の位置をずらしてワイヤソー緊張状態を保持するようにした切断方法であるので、従来の切断方法のようにワイヤソー切断の進行に伴って常にワイヤソーの緊張状態を維持するための複雑な保持機構が不要となり、操作自体も簡素化される効果を有する。 Fourth, in a method of attaching and cutting a wire saw cutting device to the tip of an arm of a self-running machine, a guide pulley for guiding the wire saw is provided at the tip of the wire saw cutting device, and the wire saw is wound around the core hole previously drilled. When the pulley is entered, the wire saw is moved to cut the workpiece that touches the wire saw, and the tension of the wire saw is insufficient due to cutting, the position of the self-propelled machine is adjusted and the position of the entire wire saw cutting device is shifted Since it is a cutting method that maintains the wire saw tension state, a complicated holding mechanism for constantly maintaining the wire saw tension state is not required as the wire saw cutting progresses as in the conventional cutting method, and the operation itself is also performed. Has the effect of being simplified.

旋回上下左右前後可能ブームアームを備えた自走機械のアーム先端に押し切り用ワイヤソー装置を取り付けた切断装置において、
押し切り用ワイヤソー装置はワイヤソーを案内する複数の支持棒とプーリと先端側ガイドプーリの付近に位置保持用ガイドローラを設け、支持棒が反対側ガイドプーリ側に撓むのを阻止する構成とし、
ワイヤソー装置の自走機械との取り付けブラケットの平面板に軸を設け、同心の周囲位置に設けたボルトで下側ブラケットと締結して取り外し可能に一体化した切断装置であり、
更に、自走機械のアーム先端にワイヤソー切断装置を取り付けて押し切りをする方法において、ワイヤソー切断装置の先端にワイヤソーを誘導するガイドプーリを設け、先に穿孔したコア孔にワイヤソーを巻き付けたガイドプーリを進入させ、ワイヤソーを移送させてワイヤソーに接する被切断物を切断し、かつワイヤソーが切断に伴って緊張状態が不足した場合に自走機械の位置を調節ワイヤソー切断装置全体の位置をずらしてワイヤソー緊張状態を保持するようにした切断方法である。 In a cutting device in which a wire saw device for push-off is attached to the tip of an arm of a self-propelled machine equipped with a boom arm capable of turning up, down, left and right,
The push-saw wire saw device is provided with a plurality of support rods for guiding the wire saw, a pulley for holding the position, and a guide roller for position holding in the vicinity of the front end side guide pulley, and is configured to prevent the support rod from bending toward the opposite guide pulley side,
It is a cutting device that is integrated in a removable manner by providing a shaft on the flat plate of the mounting bracket with the self-propelled machine of the wire saw device, and fastening with the lower bracket with bolts provided at the concentric peripheral position,
Furthermore, in the method of attaching and cutting the wire saw cutting device to the tip of the arm of the self-propelled machine, a guide pulley for guiding the wire saw is provided at the tip of the wire saw cutting device, and the guide pulley in which the wire saw is wound around the core hole previously drilled is provided. When the wire saw is cut and the workpiece to be in contact with the wire saw is cut, and when the wire saw is short of tension due to cutting, the position of the self-propelled machine is adjusted. This is a cutting method in which the state is maintained.

図１は本発明装置の一実施例を示す側面図である。バックホー・油圧ショベルのアーム（図示せず）に取り付けられるブラケット１０に取り付けたワイヤソー駆動装置２０が設けられる。駆動装置２０はワイヤソーのガイドシーブ２４が内蔵の油圧モータで回転駆動される。更にワイヤソーで押し切りするため、駆動装置２０の先端部に支柱３１が取り付けられ、支柱３１には左右に延長したガイドプーリ用軸受棒３２が設けられている。そして軸受棒３２の先端にガイドプーリ３０が左右夫々回転可能に取り付けられ、ワイヤソー９の案内をする。更に軸受棒３２の先端から被切削物に予め穿設したコア孔に挿入可能な大きさのガイドプーリ４１を支持する支持棒４２がガイドプーリ３０側より夫々直交配置されて延長形成される。支持棒４２はワイヤソー引き切りの際には、取り外すことが可能となる。   FIG. 1 is a side view showing an embodiment of the device of the present invention. A wire saw driving device 20 attached to a bracket 10 attached to an arm (not shown) of a backhoe hydraulic excavator is provided. The drive device 20 is rotationally driven by a hydraulic motor with a built-in guide sheave 24 of a wire saw. Furthermore, in order to push it out with a wire saw, a support post 31 is attached to the tip of the drive device 20, and the support post 31 is provided with a guide pulley bearing rod 32 extending left and right. And the guide pulley 30 is attached to the front-end | tip of the bearing rod 32 so that rotation on either side is possible, and the wire saw 9 is guided. Further, support rods 42 that support guide pulleys 41 of a size that can be inserted into core holes that are drilled in advance from the tip of the bearing rods 32 are arranged orthogonally from the guide pulley 30 side. The support bar 42 can be removed at the time of wire saw cutting.

したがって、駆動装置２０側のガイドシーブ２４からガイドプーリ３０、４１に夫々ワイヤソー９を掛け渡すことにより、図１に示すように、駆動装置２０が前進移動するにしたがって全体が移動することになり、ワイヤソー９の弛みをキャンセルするための大がかりな装置は不要となる。 Therefore, by passing the wire saw 9 from the guide sheave 24 on the drive device 20 side to the guide pulleys 30 and 41, respectively, as shown in FIG. 1, the entire device moves as the drive device 20 moves forward. A large-scale device for canceling the slack of the wire saw 9 becomes unnecessary.

駆動装置１０の詳細は、図２及び図３に示す。１０はバックホーブラケットを示し、ブラケット１０は上側が自走機械例えばバックホー（油圧ショベル）のアーム先端のピン取り付け孔の位置と一致するように横方向に穿設した支軸用ピン孔１１が２カ所設けられ、下側がワイヤソー駆動装置を支持するためのブラケット１２とされ、双方はボルト１３で回動可能に締結されている。すなわち図２に示すように、ブラケット１０の平面板１０ａに対し垂直の軸１４が植設固定され、下側のブラケット１２には軸１４が回動可能な孔が設けられている。尚、軸１４の取り付け関係は反対としても良い。そして軸１４の中心と同心位置に任意の角度例えば４５度毎にボルト１３が取り付けられている。 Details of the driving device 10 are shown in FIGS. Reference numeral 10 denotes a backhoe bracket. The bracket 10 has two support pin holes 11 drilled laterally so that the upper side thereof coincides with the position of the pin mounting hole at the arm tip of a self-propelled machine such as a backhoe (hydraulic excavator). The lower side is a bracket 12 for supporting the wire saw driving device, and both are fastened by a bolt 13 so as to be rotatable. That is, as shown in FIG. 2, a shaft 14 perpendicular to the flat plate 10 a of the bracket 10 is planted and fixed, and the lower bracket 12 is provided with a hole through which the shaft 14 can rotate. The mounting relationship of the shaft 14 may be reversed. Bolts 13 are attached at an arbitrary angle, for example, every 45 degrees, at a position concentric with the center of the shaft 14.

したがって、ブラケット１０に対し下側のブラケット１２は所定の角度任意に回動可能となり、ワイヤソー駆動装置２０のガイドシーブ２４の延長方向がアームの軸心に対して水平面で傾けることが可能となる。またブラケット１０，１２に対し駆動装置２０が水平方向に設けた軸１６を設け、軸１６を中心に駆動装置２０が傾斜可能にボルト２１で取り付けられている。そのため垂直面と水平面に対して任意の角度で駆動装置２０すなわちガイドシーブ２４の回転面を傾斜させることができる。 Accordingly, the lower bracket 12 can be rotated at a predetermined angle with respect to the bracket 10, and the extending direction of the guide sheave 24 of the wire saw driving device 20 can be inclined with respect to the axis of the arm in a horizontal plane. Further, a shaft 16 provided in the horizontal direction by the driving device 20 is provided to the brackets 10 and 12, and the driving device 20 is attached to the bracket 16 by a bolt 21 so as to be tiltable around the shaft 16. Therefore, the rotation surface of the drive device 20, that is, the guide sheave 24 can be inclined at an arbitrary angle with respect to the vertical plane and the horizontal plane.

図中、２１は駆動装置の基台、２２は油圧モータ、２３は制御弁、２５はガイドシーブ２４の回転軸受、２６は回転駆動軸、２７はガイドシーブ２４のカバー、２８，２９はカバーを示す。 In the figure, 21 is a base of the drive device, 22 is a hydraulic motor, 23 is a control valve, 25 is a rotary bearing of the guide sheave 24, 26 is a rotary drive shaft, 27 is a cover of the guide sheave 24, 28 and 29 are covers. Show.

この装置は、図１に示すように、支柱４２の内側すなわち他の支柱４２に面する側に、ガイドローラ５１がローラ回転軸５２及び支持棒５３と共に一体に取り付けられている。尚、図示の一点鎖線はコア孔の内面を示し、使用に際してはガイドローラ５１が常にコア孔の内壁に接するように調整される。 In this apparatus, as shown in FIG. 1, a guide roller 51 is integrally attached together with a roller rotating shaft 52 and a support bar 53 on the inner side of the column 42, that is, on the side facing the other column 42. The dashed line in the figure indicates the inner surface of the core hole, and in use, the guide roller 51 is adjusted so as to always contact the inner wall of the core hole.

そのためガイドローラ５１は、図４に示すように、ガイドローラ５１がコア孔６１の内壁に接するため、支柱４２が上下に変動しなくなるので、初期設定した切断位置を安定して保持しうることになる。 Therefore, as shown in FIG. 4, since the guide roller 51 is in contact with the inner wall of the core hole 61, the support post 42 does not fluctuate up and down, so that the initially set cutting position can be stably held. Become.

次に切断装置の動作を説明する。被切断物例えば構造物のコンクリートの塊や採石場の自然の石に対し、図５に示すように、所定位置に先に開けたコア孔６１に進入した左右のガイドプーリ４１はワイヤソーの被切断物との抵抗が生じ、夫々反対側のガイドプーリ４１側に引き寄せられてガイドプーリ４１がコア孔６１に接して更に抵抗を作ることがあるが、支柱４２のガイドプーリ４１付近に設けたガイドローラ５１によって、図４に示すように、コア孔６１の内周面に接して移動するため、ガイドプーリ４１がコア孔６１に接して発生する摩擦抵抗が大きくなることを解消できる。この場合、ガイドプーリの位置は、図４に示すように、ガイドローラ５１の外周面がコア孔６１の内周面に接するため、下がることがなくその位置がほぼ正確に保持することができる。 Next, the operation of the cutting device will be described. As shown in FIG. 5, the left and right guide pulleys 41 that have entered the core hole 61 previously opened at a predetermined position are to be cut by a wire saw, for an object to be cut, such as a concrete block of a structure or a natural stone in a quarry. There is a case where resistance to the object is generated and the guide pulley 41 is attracted to the opposite side of the guide pulley 41 side, and the guide pulley 41 comes into contact with the core hole 61 to make further resistance. However, the guide roller provided near the guide pulley 41 of the column 42 As shown in FIG. 4, 51 moves in contact with the inner peripheral surface of the core hole 61, so that it is possible to eliminate an increase in frictional resistance generated when the guide pulley 41 contacts the core hole 61. In this case, as shown in FIG. 4, since the outer peripheral surface of the guide roller 51 is in contact with the inner peripheral surface of the core hole 61, the position of the guide pulley can be held almost accurately without being lowered.

この場合、基準となるバックホーのアーム延長方向に対し平行に設定したワイヤソー駆動装置すなわちガイドシーブの向きを必要な角度に変更するには、ブラケット１０，１２の締結用ボルト１３，２１ａを一旦取り外して所定角度例えば４５度軸１４，１６を中心に回動することにより、自走機械の本体の水平面及び垂直面に対し例えば４５度その他の傾斜角度を持つワイヤソー駆動装置となる。そのためメインガイドシーブ２４の回転面が基準面より４５度又はその他の角度での傾斜状態で回転可能となりかつ前後の移動も同様に４５度傾斜面をそのまま保持して動作することになる。 In this case, in order to change the orientation of the wire saw driving device, that is, the guide sheave set parallel to the reference backhoe arm extension direction to a necessary angle, the fastening bolts 13 and 21a of the brackets 10 and 12 are temporarily removed. By rotating around a predetermined angle, for example, 45 degrees axes 14 and 16, a wire saw driving device having an inclination angle of, for example, 45 degrees with respect to the horizontal and vertical planes of the main body of the self-propelled machine. Therefore, the rotation surface of the main guide sheave 24 can be rotated in an inclined state at 45 degrees or other angle from the reference surface, and the forward and backward movement is similarly performed while holding the inclined surface as it is.

そのため切断箇所において、切断対象でない障害物等があった場合に、自走機械が基準の平行位置では充分な必要なワイヤソー切断が困難となったとき、ブラケット１０に対しネジ１３，２１ａを外して必要な角度に設定し直して用いることができるため、必要な傾斜面に対する切断や障害物に影響されることなくワイヤソー切断が可能となる。   Therefore, when there are obstacles that are not to be cut at the cutting location, when it is difficult for the self-propelled machine to sufficiently cut the wire saw at the reference parallel position, the screws 13 and 21a are removed from the bracket 10. Since it can be set to a necessary angle and used again, a wire saw can be cut without being affected by a necessary cutting with respect to an inclined surface or an obstacle.

自走機械例えばクローラ式・タイヤ式のバックホー・油圧ショベルのアーム先端に設けて使用し、コンクリート・石材・ＦＲＰ材その他一般的な硬質な物の切断装置に適用可能である。 It can be used on self-propelled machines such as crawler type / tire type backhoes / hydraulic excavator arm tips, and can be applied to cutting devices for concrete, stone, FRP materials and other general hard objects.
