CAISSON TYPE PILE EXCAVATOR
To provide a caisson type pile excavator that can reduce an operator burden by assisting a driving operation when a bucket is lowered in an excavation pit to land on an excavation surface.SOLUTION: In a caisson type pile excavator 1 having a bucket 13 connected to a tip of a multi-stage expansion arm 6, a distance sensor 21 is provided at a lower end of a base end arm 6a constituting the expansion arm 6, and a distance L to an excavation surface Sa in an excavation pit S is detected. A reference distance L0 from the distance sensor 21 to a lower end of the bucket 13 and an expansion amount L1 of the expansion arm when the expansion arm 6 is in a most shrunken state are subtracted from the distance L, and a separation distance L3 from a lower surface of the bucket 13 to the excavation surface Sa is calculated. When an angle of the expansion arm 6 is within a prescribed angle region α including a vertical direction and the expansion arm 6 is driven in an expanding direction, considering that the bucket 13 is being lowered in the excavation pit S, the separation distance L3 is notified to an operator through a display 25 and a speaker 26.SELECTED DRAWING: Figure 5
【課題】掘削坑内でバケットを下降させて掘削面に着地させる際の運転操作を支援して、オペレータの負担を軽減できる深礎掘削機を提供する。【解決手段】多段式伸縮アーム６の先端にバケット１３を連結した深礎掘削機１において、伸縮アーム６を構成する基端アーム６ａの下端に距離センサ２１を設けて、掘削坑Ｓ内の掘削面Ｓａまでの距離Ｌを検出する。この距離Ｌから、伸縮アーム６が最収縮状態のときの距離センサ２１からバケット１３の下端までの基準距離Ｌ0、及び伸縮アームの伸長量Ｌ1を減算し、バケット１３の下面から掘削面Ｓａまでの離間距離Ｌ3を算出する。伸縮アーム６の角度が鉛直方向を含む所定の角度領域α内にあり、且つ伸縮アーム６が伸長方向に駆動されている場合、掘削坑Ｓ内でバケット１３が下降中であると見なし、離間距離Ｌ3をディスプレイ２５及びスピーカ２６でオペレータに報知する。【選択図】図５
