摘要:
An excavator for underground excavating arranged to perform excavating work with low vibration and low noise. A rotary excavator and an underground excavating method are also provided. The excavator (1) for underground excavating comprises a plurality of bits (42a,...) having the outside diameter smaller than that of the excavator body (2) and advancing/retracting to/from the excavating side, piston case members (22b,...) incorporating pistons (61) for applying a hitting force to respective bits (42a,...) by the energy of working fluid, a section (30) for storing the working fluid being fed to respective piston case members (22b,...), working fluid circulation passages (352) for allowing the working fluid being fed to respective piston case members (22b,...) to pass, and a body of rotation (40) provided with a plurality of holes (4a,...) for allowing the fluid storage section (30) to communicate with the circulation openings (3a,...) of each working fluid circulation passage (352) in order to feed the working fluid from the fluid storage section (30) to the circulation openings (3a,...) of the respective working fluid circulation passages (352).
摘要(中):
用于地下挖掘的挖掘机布置成执行低振动和低噪声的挖掘作业。 还提供旋转挖掘机和地下挖掘方法。 用于地下挖掘的挖掘机(1)包括具有小于挖掘机主体(2)的外径的多个钻头(42a,...)并且从挖掘侧进出的活塞箱构件(22b ,...),其结合用于通过工作流体的能量将击打力施加到各个钻头(42a,...)的活塞(61),用于存储被供给到相应的活塞壳体构件的工作流体的区段(30) 22b,...),工作流体循环通道(352),用于允许将工作流体供给到相应的活塞箱构件(22b,...)通过;以及旋转体(40),其设置有多个孔 (4a,...),用于允许流体存储部分(30)与每个工作流体循环通道(352)的循环开口(3a,...)连通,以便从流体存储部分 (30)连接到各个工作流体循环通道(352)的循环开口(3a,...)。
