In addition to facilitating the holding of the mast angle, the mast should be kept parallel to the bedrock when changing the mast angle during work, and only the cell swing and cell tilt can be used. Since it is possible to change the angle, the angle can be easily changed.
従って 6 個所の 自由度を持つ部分を操作して差 し込み 角を設定する ものに比べて操作が容易 と なる と共に ， 掘 削作業中に差 し角 を変更する場合も， 岩盤 1 8に対 してマ ス ト 6 を平行に維持 しておけば， セ ノレス イ ング シ リ ンダ 1 2と セ ルチル ト シ リ ンダ 1 6のみで差 し角 の変更が行え る よ う にな る。  Therefore, the operation is easier than when the insertion angle is set by manipulating a part with six degrees of freedom, and when the insertion angle is changed during excavation work, the rock mass 18 If the mast 6 is kept parallel in this way, the slip angle can be changed only with the cylinder 12 and the cylinder 16.
一方マス ト 6 の上部には通常各種シ リ ンダゃロ ーテ一 タ な どの ァ ク チユ エ 一タが設け られてお り ， これ らのァ ク チ ユ エ一タ には複数本の高圧ホースよ り な る ホース類 2 0を介して本体 1 側よ り 油圧が供給されてい る。  On the other hand, actuating devices such as various cylinder rotators are usually provided at the upper part of the mast 6, and these actuating devices are provided with a plurality of high-voltage devices. Hydraulic pressure is supplied from the main unit 1 side through the hoses 20 made of a hose.
上記ホ ー ス類 20の一端側はマ ス ト ロ ーテ一タ 7 の前部 で第 4 図に示すよ う に本体 1 側の配管 2 1に接続さ れ， 他 端側はマ ス ト 6 上部に設け られた各種ァ ク チ ユ エータ に 接続されてい る と共に ， 中間部はホースガイ ド 22によ り 支持されてい る。 一 Ί 一 上記ホ ー ス ガイ ド 22は多数の リ ン ク 22 a を連結 した 2 列のチ ェ ー ン 22 b によ り 構成さ れ， 各チ ヱ 一 ン 22 b 間は 複数の支持杆 22 c によ り 一定の間隔 と な る よ う に連結さ れて い る。 One end of the hoses 20 is connected to the piping 21 of the main body 1 as shown in Fig. 4 at the front of the mast rotator 7, and the other end is connected to the master. 6 Connected to various actuators provided at the upper part, and the intermediate part is supported by hose guide 22. The above-mentioned hose guide 22 is composed of two rows of chains 22b connecting a large number of links 22a, and a plurality of support rods are provided between each chain 22b. They are connected so that they are spaced at a fixed interval according to 22c.
上記チ ヱ ー ン 22 b の一端側はマ ス ト 6 の前面に縦方向 に設け られたチヱ ー ンガイ ド 23の上部に接続さ れてい る と共に， 他端側はマ ス ト 6 上部よ り 突設されたブ ラ ケ ッ ト 6 a の先端に接続さ れて い る 。  One end of the chain 22b is connected to the upper part of a chain guide 23 provided vertically on the front of the mast 6, and the other end is higher than the upper part of the mast 6. It is connected to the tip of the protruding bracket 6a.
そ して こ れ ら チ ェー ン 22 b の間に内側よ り ホース類 20 が収容さ れて い て ， ホー ス類 20は各支持杆 22 c の間に設 け られた ク ラ ンプサポータ 22 d を介 して チ ェ ー ン 22 b 間 に ク ラ ンプさ れている。  The hoses 20 are housed between the chains 22b from the inside, and the hoses 20 are clamp supporters 22 provided between the support rods 22c. It is clamped between chains 22b through d.
次に作用を説明する と， 岩盤を掘削す る に 当 っ て ， 岩 盤を掘削する ロ ッ ド 17が掘削位置に達す る よ う マス ト 6 を伸縮動する が， こ れに伴いマス ト 6 上のブ ラ ケ ッ ト 6 a よ り 垂下さ れたホー スガ イ ド 22も伸縮動 して， マス ト 6 上部に設け られたァ ク チ ユ エ 一タ へ油圧を供給する ホ 一ス類 20を支持する。  Next, the operation will be described. In excavating the rock, the rod 6 for excavating the rock expands and contracts the mast 6 so as to reach the excavation position. The hose guide 22 suspended from the upper bracket 6a also expands and contracts to supply hydraulic pressure to the actuator unit provided at the upper part of the mast 6. Support class 20.
こ れに よ つ てホ ー ス類 20が互にか らんだり ， 他装置 と 干渉する こ とがない と共に ， ホース類 20の下部に適当 な 曲線を確保で き る よ う にな る。  Thus, the hoses 20 do not entangle with each other or interfere with other devices, and an appropriate curve can be secured at the lower part of the hoses 20.
ま たマス ト 6 の縮小に伴い こ の曲線部はチ ェ ー ンガ イ ド 23に沿 っ て下降する ため， チ ェー ンガ イ ド 23がチェ 一 ン 22 b を案内 し， チ ヱ ー ン 22 b が捩れる のを防止する よ う にな る 。  In addition, as the mast 6 is reduced, the curved portion descends along the chain guide 23, so that the chain guide 23 guides the chain 22b and the chain. 22b is prevented from twisting.
なお第 4 図に示 した も の は岩盤掘削機の場合で あ る が， 伸縮する マス ト の上部に油圧な どによ り 駆動をさ れる ァ ク チ ユ エータ が設け られた作業機を有する建設機械全般 に適用で き る も のであ る。 産業上の利用可能性 The one shown in Fig. 4 is for a rock excavator. The present invention can be applied to all construction machines having a working machine provided with an actuator driven by hydraulic pressure or the like on the top of an expanding mast. Industrial applicability
こ の発明は以上詳述 した よ う にな るか ら， 作業機の 自 由度を有する 部分が従来の 6 個所か ら 5 個所にな る た め 操作個所が少な く な り ， 操作が容易 とな る。  As described in detail above, the invention has fewer parts to be operated since the work equipment has a degree of freedom from six to five instead of the conventional six parts, thus facilitating operation. It becomes.
しかも こ の 5 個所の 自由度を持つ部分を操作する だけ で， 岩盤に対する セ ルの差 し角 が設定で き る よ う にな り セ ルの位置決めや岩盤に対する差.し角 の設定が従来の も の に比べて容易になる。  In addition, it is possible to set the cell difference angle with respect to the rock only by operating these five degrees of freedom, so that the positioning of the cell and the setting of the difference angle with respect to the rock can be done conventionally. It will be easier than others.
ま たセ ルの差し角がセ ルス ィ ング と セ ルチル ト の作動 だけで決ま り ， 作業機の他の自 由度を有する部分の作動 の影響を受け る こ とがないため， 差 し角 の保持が容易に な る と共に， 作業中差 し角 を変更す る場合も， マ ス ト を 岩盤 と平行になる よ う に保持 しておけば， セ ルス イ ン グ と セ ルチル ト のみで行う こ とができ るため， 差し角 の変 更が容易に行える 。  Also, the angle of contact of the cell is determined only by the operation of the cell swing and the cell tilt, and is not affected by the operation of the other parts of the work equipment that have freedom, so the difference in angle In addition to making it easier to hold the mast and changing the bevel angle during work, if the mast is held parallel to the bedrock, only the cell swing and the cell tilt can be used. The angle can be easily changed.
さ ら にま た こ の発明では伸縮自在なマ ス ト の上部よ り 垂下された複数の ホー ス類をチ ェー ン状のホースガイ ド に よ り 支持した こ と力、 ら， マス 卜 の伸縮に伴いホース類 が伸縮 して も， ホ ース類が捩れた り ， ホ ース類同士が擦 れた り ， から んだ り ， ま た垂れさ がつ たホー ス類が他装 置と干涉する こ とがない。  Further, in the present invention, a plurality of hoses suspended from the upper part of the telescopic mast are supported by a chain-shaped hose guide, and the force and the mass of the mast are increased. Even if the hoses expand and contract with expansion and contraction, the hoses may be twisted, the hoses may be rubbed against each other, or the hoses may be entangled or drooping. Never dry out.
こ れによ つ てホース類が早期に磨耗 した り ， 破損す る こ と がな く ， ホ ー ス類の耐久性を飛躍的に向上す る こ と がで き る よ う に な る 。 This can cause hoses to wear or break prematurely Without this, the durability of the hoses can be dramatically improved.
ま たホ ース類の下部に適当 な径の 曲線部を形成す る こ と がで き る た め， ホ ー ス類が急激に 曲 げ ら れて傷むな ど の おそれがな い と共に ， 曲線部の上部動を案内す る チ ェ ー ン ガ イ ドを設け る こ と に よ り ， ホ ー ス ガ イ ドが捩れる こ と がな いた め， ホ ー ス類の円滑な上下動が可能に な る  Also, since a curved portion having an appropriate diameter can be formed at the lower part of the hose, there is no danger of the hose being sharply bent and being damaged. By providing a chain guide that guides the upward movement of the curved part, the hose guide is not twisted, so that the hoses can move up and down smoothly. Become possible
