岩土钻掘设备的液压步履机构

Hydraulic Moving Mechanism of Drilling and Tunneling Equipment

因液压步履移位最方便,辅助时间短,换向灵活,移位对孔准确,大型岩土钻掘设备施工的群孔现场实现近距离的自行迁移多采用液压步履机构。详细叙述了双向移动和单向移动加转向步履机构的结构和特点。

Because the hydraulic moving mechanism can move conveniently, change direction quickly, locate the borehole position accurately, and need short auxiliary time, most of the big drilling and tunneling machines adopted it for moving between boreholes in site. The structure and traits of two direction moving mechanism and one direction moving mechanism with rotation were introduced.
