Title:
掘削またはボーリング装置用アセンブリおよび作動方法
Document Type and Number:
Japanese Patent JP7245248
Kind Code:
B2
Abstract:
An assembly for driving excavating equipment for an excavating machine includes a drive assembly sliding along a mast of a machine, for driving the drilling equipment; and an actuator. The drive assembly includes a first structure with guide members for sliding along the mast; and a second support structure to support the drilling equipment. The first and second support structures are mutually movable. The drive assembly has at least two operating configurations, for setting at least two excavation center-to-center distances. In the operating configurations of the drive assembly, the first and second support structures are mutually rigidly and directly constrained. While switching between operating configurations, the first and second support structures are always directly mechanically constrained to each other. The actuator controls movement between the first structure and the second support structure and carries out further operative functions for driving parts of an excavating machine or drilling equipment.
