DEVICE FOR CONSTRUCTION WORK ATTACHMENT FOR CONSTRUCTION WORK AND CONSTRUCTION EQUIPMENT HAVING THE SAME

摘要

The present invention relates to an apparatus for construction work such as pile driving and drilling and an attachment for construction work, and a construction equipment comprising the same. According to the present invention, the apparatus for construction work, which is used for construction base work such as pile driving and drilling by being mounted on a leader installed in a carrier, may comprise: a body connected to the leader; a mounting unit which performs fastening and escape from an object to be fastened such as a pile or a screw by receiving an oil pressure placed on a bottom side of the body in order to be able to allow a direction of receiving the object to be fastened to tilt from a direction parallel to a longitudinal direction of the leader up to the direction vertical to the longitudinal direction of the leader; a tilting unit which receives an oil pressure to tilt the mounting unit in the vertical direction; an oil pressure line which connects the mounting unit and an oil pressure source to apply oil pressure to the mounting unit; a control valve placed on the oil pressure line to allow the oil pressure line to apply one or more oil pressure of an oil pressure to fasten and an oil pressure for escaping to the mounting unit; a fastening maintenance line branched from the oil pressure line to force the mounting unit to perform fastening; and a fastening maintenance valve which connects or block the fastening maintenance line. The present invention is to provide an apparatus for construction work and an attachment for construction work and an equipment comprising the same, capable of allowing easy replacement of a pile or a screw in an attachment of a pile driver or a drilling machine.
