である。 By detecting that the elevating object has come off the guide using the device of the present invention and immediately stopping the movement of the elevating object,
Accidents can be prevented from escalating, but the movement of the lifting object can be stopped manually by an operator by issuing an alarm using an electrical signal from a detector, or by automatic control directly using an electrical signal from a detector. or it is optional.

ヤ５でリーダー６の一側面に沿つて吊下げられ、
リーダー６と対向する側面に取付けたスライダー
７をリーダー６のガイド８に係合させた状態で上
下に移動するようになつている（第１図参照）。 A casing 4 is attached below the penetration machine 1 via a hopper section 3, and the penetration machine 1 is suspended along one side of a leader 6 by a wire 5.
A slider 7 attached to the side opposite to the leader 6 is adapted to move up and down while being engaged with a guide 8 of the leader 6 (see FIG. 1).
昇降バケツト２はワイヤ９でリーダー６の一側
面に沿つて吊下げられ、リーダー６と対向する側

ガイド８′に係合させた状態で上下に移動するよ
うになつている（第２図、第３図参照）。 The lifting bucket 2 is suspended along one side of the leader 6 by a wire 9, and is moved up and down while a guide clamp 10 attached to the side facing the leader 6 is engaged with a guide 8' of the leader 6. (See Figures 2 and 3).
貫入機１と昇降バケツト２は互いに関連がない

るようになつている。 Although the penetrating machine 1 and the lifting bucket 2 are shown as having no relation to each other, in reality, each side of the leader 6 through which the penetrating machine 1 and the lifting bucket 2 are guided are adjacent to each other, and the hopper section is connected from the lifting bucket 2 to the leader 6. 3
Sand can be supplied into the casing 4 through the casing 4.

を自動的に制御して行えばよい。 When an elevating object becomes unguided, the movement of the elevating object is immediately stopped, and the stoppage of movement of the elevating object is notified to the operator by activating an appropriate alarm using an electrical signal output from the detector 11. This may be done manually or by automatically controlling the control mechanism of the moving power source (for example, a hydraulic motor) using an electrical signal from the detector 11.
なお、軟弱地盤攪拌混合処理装置における回転
軸の回転駆動部等の他の昇降体の場合も前述と同
様であるので、その具体的説明は省略する。 Incidentally, since the case of other elevating bodies such as the rotation drive unit of the rotary shaft in the soft ground stirring and mixing treatment apparatus is the same as that described above, a detailed explanation thereof will be omitted.
