Abstract

本实用新型公开一种土压平衡盾构机的双刃滚刀。刀体上固连有两圈滚刀，刀体心部套连轴承，滚刀的刃口沿轴向向两边延伸为一加宽的刃口。刃口的宽度较佳为25mm。采用这样的结构，由于刃口加宽，使滚刀的抗磨损性能提高，从而提高刀具使用寿命。使其在富水砂卵石地层情况下使用，掘进速度提高，掘进成本降低。

Description

双刃滚刀
技术领域
本实用新型涉及一种土压平衡盾构机的刀盘所使用的双刃滚刀。
背景技术
当使用土压平衡盾构机在富水砂卵石地段掘进时，刀具的磨耗非常严重，平均120～150m就需全部或大部分更换一次刀具。现有的17″双刃滚刀在富水砂卵石地层掘进时，掘进速度太慢，刀具磨损严重，换刀频繁，掘进成本较大。
实用新型内容
本实用新型要解决的技术问题是提供一种可有效提高耐磨性的双刃滚刀。
为解决上述技术问题，本实用新型的双刃滚刀，刀体上固连有两圈滚刀，刀体心部套连轴承，滚刀的刀圈刃口沿轴向向两边延伸为一加宽的刃口。刃口的宽度较佳为23-27mm。采用双刃滚刀，比单刃型既耐磨又提高掘进效率，由于刃口加宽，使滚刀的抗磨损性能提高，从而提高刀具使用寿命。使其在富水砂卵石地层情况下提高掘进速度，降低掘进成本。
附图说明
本实用新型将通过实施例并参照附图的方式说明：
图1是本实用新型结构示意图。
具体实施方式
如图1所示的本实用新型双刃滚刀，刀体3上固连有两圈滚刀2，滚刀的外径D30为531.3mm，两圈滚刀的中心距B31为100mm。刀体心部套连轴承4，所述两圈滚刀的刃口1沿轴向向两边延伸为一加宽的刃口。刃口的宽度B30为23-27mm，尤其是25mm时较佳。
