Description
ショベルマシンに取り付けられる散水圧砕機、特に反力自由回動式の散水圧砕機に使用するスイベルジョイント装置に関する。 The present invention relates to a sprinkler crusher attached to an excavator machine, and more particularly to a swivel joint device used for a sprinkler crusher of a reaction force free rotation type.
コンクリート構造物の解体作業には、従来から、開閉自在に枢支された一対の圧砕アームを対向する油圧シリンダーによって開閉して前記圧砕アームに挟持された被破砕物を圧砕する圧砕機が、ショベルマシンのブームの先端に取付用ブラケットを介して着脱自在に取り付けられて使用されてきた。
そして、前記圧砕機は、先端側である圧砕アーム側と、後端側であるブラケット側が分離され、圧砕アーム側がブラケット側に対して回動可能に装着されている。したがって、前記圧砕アームが被破砕物を斜めに挟み込んだ場合でも、アームを閉じて被破砕物に圧力を加えるとその反力によって、圧砕アームが被破砕物に対し直角となる向きに回動し、被破砕物に対してその圧砕力を有効に伝達することができる。
このような圧砕機は、ショベルマシンを移動しなくても、圧砕アームが自ら反力自由回動して圧砕物を常に有効に圧砕するので、コンクリート構造物の解体作業を非常に効率よく行うことができる。
また、前記圧砕機には、圧砕アームを枢支するフレーム部に、被圧砕物に向けて散水できる散水ノズルが備えられるようになっており、散水によって圧砕時の粉塵の発生を防止することもできる。
Conventionally, a crusher for crushing a material to be crushed by opening and closing a pair of crushing arms pivotally supported so as to be freely opened and closed by opposing hydraulic cylinders and crushing the object to be crushed has been used for dismantling the concrete structure. It has been used by being detachably attached to the tip of a machine boom via a mounting bracket.
In the crusher, the crushing arm side which is the front end side and the bracket side which is the rear end side are separated, and the crushing arm side is mounted so as to be rotatable with respect to the bracket side. Therefore, even when the crushing arm sandwiches the object to be crushed obliquely, when the arm is closed and pressure is applied to the object to be crushed, the reaction force causes the crushing arm to rotate in a direction perpendicular to the object to be crushed. The crushing force can be effectively transmitted to the object to be crushed.
Such a crusher does not move the excavator machine, but the crushing arm rotates freely by its own reaction force and always crushes the crushed material effectively. Can do.
Further, the crusher is provided with a watering nozzle that can sprinkle toward the object to be crushed on the frame portion that pivotally supports the crushing arm, and it is also possible to prevent generation of dust during crushing by watering. it can.
例えば、本願発明者が開発した特許第３０９９４２０号「反力自由回動式散水圧砕機のスイベルジョイント構造」には、「上方のショベルマシンへの取付用のブラケットを備設した上部ローテータと、下方の圧砕用のクラッシャージョー、駆動用の油圧シリンダー並びに圧砕部への散水ノズルを備設した下部ローテータとを備えてなる反力自由回動式散水圧砕機において、前記の上部ローテータと下部ローテータとをスイベルジョイントを中心にして回動自在に接続し、該スイベルジョイントに給油孔並びに給水孔を穿設し、該給油孔並びに給水孔を介して上部ローテータ側から下部ローテータ側へ給油並びに給水可能としたことを特徴とする反力自由回動式散水圧砕機のスイベルジョイント構造」が開示されている。
上記発明により、反力自由回動の機能が有効に発揮され、被破砕物がいかなる角度で存在していても有効な圧砕力を伝達することができ、また、可撓性ホースを外部に垂下させて連結する必要がなくなり、可撓性ホースが作業の邪魔をしたり、外部の障害物に当たって破損したりして作業性を低下させる恐れがなくなり、さらに、給油源並びに給水源が簡易かつ集中的に連結でき、機能性の高い散水圧砕機が実現された。
According to the invention, the reaction force free rotation function is effectively exhibited, and an effective crushing force can be transmitted regardless of the angle of the object to be crushed, and the flexible hose is hung outside. There is no need to connect them, the flexible hose will not interfere with the work, or it will be damaged by hitting an external obstacle, and the workability will not be reduced. In addition, the oil supply source and water supply source are simple and concentrated A highly functional sprinkler crusher was realized.
しかし、反力自由回動式の散水圧砕機は、左右に自在に回転可能であるため、その振動や衝撃で給油孔と給油ホースの継ぎ目や、給水孔と給水ホースの継ぎ目に緩みが生じやすく油の中に水が混入してしまうという問題があった。
また、上記原因による水漏れにより装置に錆が生じやすくなるという問題もあった。
一方、近年、環境問題の重要性から、コンクリート構造物等の解体作業時における粉塵の発生をさらに減少させることが要望されてきていることへの対応も必要となってきていた。
本発明は上記課題に鑑み、水漏れがなく、油に水が混入することなく、錆の発生を防ぎ、かつ粉塵の発生を防ぐ散水圧砕機用のスイベルジョイント装置を提供する。
However, since the reaction force free rotation type watering crusher can be freely rotated to the left and right, the vibration and impact of the sprinkler crusher tends to loosen the joint between the oil supply hole and the oil supply hose, and the joint between the water supply hole and the water supply hose. There was a problem that water mixed into the oil.
Moreover, there also existed a problem that it became easy to produce rust by the water leak by the said cause.
On the other hand, in recent years, due to the importance of environmental problems, it has become necessary to respond to the demand for further reducing the generation of dust during the demolition work of concrete structures and the like.
