EXCAVATOR HAVING ADJUSTABLE WIDTH FOR TRACK
본 발명의 일 실시예에 따른 트랙폭 가변형 굴삭기는 궤도가 지지체에서 회전하는 하부주행체와, 하부주행체에서 선회하는 상부주행체와, 상부주행체에서 상하로 회전하는 붐조립체으로 구성되는 굴삭기로서, 궤도는 일 링크지지체와 타 링크지지체가 상호 회전가능하게 결합되는 랑크조립부와, 각각의 링크지지체에 결합되는 슈부재로 구성되며, 링크지지체는 일측에 부시가 삽입되는 부시삽입공이 관통형성되고, 타측에 핀이 삽입되는 핀삽입공이 형성되어 일 링크지지체의 핀은 타 링크지지체의 부시에 삽입되며, 슈부재에는 슈부재의 폭을 가변시키는 슈커버가 착탈되어, 본 발명에 따른 트랙폭 가변형 굴삭기는 무한궤도의 트랙을 형성하는 메인플레이트에 슈커버를 부착하여 트랙의 폭을 선택적으로 넓힐 수 있도록 함으로써 다양한 폭을 갖는 심굴작업을 보다 용이하게 할 수 있는 효과가 있다.
The present invention relates to a width-adjustable excavator for a track. The width-adjustable excavator for a track according to one embodiment of the present invention is composed of a lower driving body with a track rotating on a support body, an upper driving body turning in the lower driving body, and a boom assembly rotating upward and downward in the upper driving body. The track is composed of a link assembly unit in which one link support body and the other link support body are coupled to be mutually rotatable, and a shoe member which is coupled to each link support body. A bush insertion hole into which a bush is inserted is formed to penetrate one side of the link support body, and a pin insertion hole into which a pin is inserted is formed at the other side so that the pin of one link support body is inserted into the bush of the other link support body. A shoe cover adjusting the width of the shoe member is detachably attached to the shoe member. The width-adjustable excavator for a track according to the present invention attaches the shoe cover on a main plate forming a caterpillar track to selectively widen the width of the track, thereby facilitating excavation work with a variety of widths.
