Excavator coupler
Disclosed is an excavator coupler for coupling an excavator accessory to an arm of an excavator. The coupler includes: a body having a first recess engaged with the first pin of the accessory; a tongue-shaped member movable relative to a main body, with the tongue-shaped member having a second recess engaged with a second pin of the accessory; a lock arm pivotally mounted to the body about a fixed pivot point; and an actuator assembly mounted between the lock arm and the tongue member. An actuator assembly has a hydraulic actuator and is configured to i) move the tongue member relative to the body to facilitate engagement and disengagement of the second recess with the second pin; and ii) pivoting the locking arm to selectively prevent the first pin from exiting from the first recess. An auxiliary fail-safe mechanism in the form of a compression spring is provided such that a maximum pressure is set across the hydraulic actuator. Thus, if a hydraulic failure occurs, the compression spring continues to maintain the pressure of the tongue-like member on the second pin of the attachment, thereby ensuring that the attachment is not disconnected from the coupler.
一种挖掘机联接器，其用于将挖掘机附件联接至挖掘机的臂。联接器包括：主体，具有与附件的第一销接合的第一凹部；相对于主体能移动的舌状构件，其具有与附件的第二销接合的第二凹部；围绕固定枢轴点枢转地安装到主体的锁定臂；以及安装在锁定臂与舌状构件之间的致动器组件。致动器组件具有液压致动器并且构造成i)相对于主体移动舌状构件以利于第二凹部与第二销的接合和分离；以及ii)枢转锁定臂以选择性地阻止第一销从第一凹部退出。压缩弹簧形式的辅助故障保护机构被设置，使得在整个液压致动器上设置最大压力。因此，如果液压故障出现，压缩弹簧继续维持舌状构件在附件的第二销上的压力，从而确保附件不会从联接器断开。
