Claims

[Claims for Utility Model Registration] (1) A utility model comprising both sprockets disposed above and below a panel that is suspended from a leader and embedded, and a chain that is wound around the sprockets and has a plurality of digging tools for digging. An excavation rig that performs excavation by rotating a chain, comprising: an inclinometer for detecting the inclination of the panel; a position correction cylinder having one end connected to a lower part of the leader and the other end fixed to a location other than the leader; and an elevating cylinder whose one end is connected to the leader and the other end is connected to a predetermined position other than the leader above the position correction cylinder,
An excavation device characterized in that the position and attitude of the panel are corrected by operating the position correction cylinder and the elevation cylinder based on the detection result of the inclinometer. (2) It is equipped with both sprockets placed above and below the panel to be suspended from the leader and embedded, and a chain to which a plurality of digging tools for digging are attached, which are wound around the sprockets, and the chain is rotated to perform digging. The excavating apparatus includes a rotating part that rotates integrally with the upper end of the panel, an angle detection part that detects a rotating angle of the rotating part, and a rotating drive body that corrects the rotating angle of the rotating part. Drilling equipment characterized by:
