Abstract
본 발명은 지반굴착장치에 있어 오가머신에 수직상으로 다단 조립되는 로드(ROD)들 중 상기 오가머신에 직접 조립되는 최상단측 로드는 신축작동이 가능한 2증 로드로 구성하여 지반굴착작업시 기 연결조립된 로드의 굴착가능 깊이보다 조금 더 깊게 굴착하고자 할 때 별도의 로드를 연결조립하지 않고도 최상단측의 로드를 필요한 길이만큼 조금 더 깊게 굴착하고자 할 때 별도의 로드를 연결조립하지 않고도 최상단측의 로드를 필요한 길이만큼 신장시키는 수단으로 원하는 깊이의 굴착작업을 진행할 수 있도록 하는 지반굴착장치의 신축로드에 관한 것으로, 오가먼신의 암죠인트에 로드의 수죠인트를 삽입시킨 후 결속핀으로 결합시키는 것에 있어 상기 수죠인트의 하단에는 상, 중, 하단 접속관체와, 상기 상, 중, 하단 접속관들 사이사이에 상, 하측 연결관이 접속되는 내측 로드와, 상기 내측 로드의 상, 중, 하단 접속관체 및 상기 상, 하측 연결관 각각의 원형외주에는 외측 로드에 회전력을 전달할 수 있도록 세로방향으로 평면가공된 외면접속부와, 상기 내측 로드의 상, 중, 하단 접속관체 각각에 결속핀에 의하여 외측 로드와 결합시킬 수 있도록 형성된 외면결속홈과, 상기 내측로드의 외면저속부와 면접촉되는 내면접속부가 형성된 상측 암죠인트와, 상기 상측 암죠인트와 하측 암죠인트와의 사이에 용접되는 외통체가 구비된 외측 로드와, 상기 외측 로드의 상측 암죠인트에는 상기 내측 로드의 상, 중, 하단 접속관체에 형성된 외면결속홈들과의 사이에서 결속핀에 의하여 선택적으로 결속될 수 있도록 형성한 내면결속홈과, 상기 내측 로드의 내부에 고정상태로 장착된 가이드관에 삽입되어 상기 가이드관속을 기밀하게 밀폐되면서 내측 로드의 상, 하 이동을 가능하게 하는 공급관 및 상기 공급관의 하단에 용접되며, 상기 외측 로드의 하측 암죠인트에 삽입, 접속되는 수죠인트와, 상기 접속용 수죠인트와 일체형으로 용저되어 다음단의 로드와 연결되는 연결을 암죠인트를 구비하여서 외측 로드에서 내측 로드를 신축시킬 수 있도록 한 것을 특징으로 하는 것이다.The present invention relates to a ground excavating apparatus, in which a top load rod (ROD), which is directly assembled to an auger machine among rods (ROD) assembled vertically into an auger machine, is composed of a two- When a user wishes to excavate the assembled rod a little deeper than the excavable depth, and when the uppermost rod is to be excavated a little deeper by a required length without connecting and assembling a separate rod, In which a male joint of a rod is inserted into a female joint of an auger god and then the male joint is coupled with a binding pin, Upper, middle, and lower connecting pipe bodies and upper and lower connecting pipes between the upper, middle, and lower connecting pipes at the lower end of the male joint, An outer connecting portion formed in the outer periphery of each of the upper, middle, and lower connecting tubes of the inner rod and the upper and lower connecting pipes, the outer connecting portion being vertically flattened so as to transmit a rotational force to the outer rod; An upper arm joint formed with an outer surface coupling groove formed in each of the upper, middle and lower connection tubes of the inner rod so as to be coupled to the outer rod by a coupling pin and an inner surface connecting portion formed in surface contact with the outer surface lower portion of the inner rod; An outer rod provided with an outer cylinder to be welded between the upper arm joint and the lower arm joint; and an upper arm joint between the upper arm joint and the outer surface coupling grooves formed in upper, middle, and lower end connection tubes of the inner rod, An inner surface coupling groove formed so as to be selectively bindable by a binding pin and a guide pipe inserted in a fixed state inside the inner rod A joint pipe which is welded to a lower end of the supply pipe and inserted into and connected to a lower arm joint of the outer rod, So that the inner rod can be expanded and contracted in the outer rod by providing an arm joint in the connection which is connected to the rod in the next stage.
