| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an entire rotary casing press-in device with light weight and lower total height capable of reducing a bending load applied to each part of a lifting mechanism by devising a layout of a lifting cylinder and horizontal jack and a support constitution and facilitating installation and assembly.SOLUTION: An entire rotary casing press-in device comprises: a base frame 1 connected to the ground; a lifting frame 2 formed on the base frame 1 so that the lifting frame can move up and down by a lifting mechanism 3; a chuck mechanism to fix a casing R; and a drive rolling mechanism 11 to drive the fixed casing R to rotate. A horizontal jack 29 that corrects an inclination of the base frame 1 is concentrically disposed and directly installed below a lifting cylinder 4 of the lifting mechanism 3.SELECTED DRAWING: Figure 1
【課題】昇降シリンダと水平ジャッキの配置および支持構成を工夫し、昇降機構の各部への曲げ荷重負担を抑制すると共に、取付および組立を容易にして、軽量コンパクトで全体高さの低い全旋回ケーシング圧入装置を提供する。【解決手段】地盤上に接地するベースフレーム１と、ベースフレーム１上に昇降機構３にて昇降自在に設けた昇降フレーム２と、ケーシングＲを固定するチャック機構と、固定したケーシングＲを駆動回転させる駆動回転機構１１とを有し、前記昇降機構３の昇降シリンダ４の下方に、前記ベースフレーム１の傾斜を修正する水平ジャッキ２９を同心上に配置し、かつ、直接的に取付けるように全旋回ケーシング圧入装置。【選択図】図１ |
