Boom lock device and work machine
The invention relates to the technical field of engineering machinery, and provides a movable arm locking device and an operation machine.The movable arm locking device comprises a first limiting hook, a second limiting hook, a first flexible shaft and a locking mechanism, the first limiting hook is fixedly arranged on a movable arm, and the second limiting hook is arranged on a deflection platform in a fixed-axis rotating mode; the second limiting hook can be clamped with or separated from the first limiting hook; the first flexible shaft is connected to the second limiting hook and controls rotation of the second limiting hook. The locking mechanism is arranged on the deflection platform, the locking mechanism can be switched between a locking state and an unlocking state, in the locking state, the locking mechanism presses the second limiting hook so that the second limiting hook can be kept at the position where the second limiting hook and the first limiting hook can be clamped, and in the unlocking state, the locking mechanism is disengaged from the second limiting hook so that the second limiting hook can rotate. By means of the arrangement, the problem that in the prior art, a movable arm locking device is prone to losing efficacy due to bumping and vibration is solved.
本发明涉及工程机械技术领域，提供一种动臂锁定装置及作业机械，其中，动臂锁定装置包括第一限位钩、第二限位钩、第一软轴和锁紧机构，第一限位钩固设于动臂，第二限位钩可定轴转动地设于偏转平台，第二限位钩能够与第一限位钩相卡接或者脱离卡接；第一软轴连接于第二限位钩，第一软轴控制第二限位钩的转动；锁紧机构设于偏转平台上，锁紧机构能够在锁紧状态与解锁状态之间切换，在锁紧状态，锁紧机构压紧第二限位钩、以使第二限位钩保持在与第一限位钩相卡接的位置，在解锁状态，锁紧机构脱离第二限位钩，以允许第二限位钩转动。如此设置，解决了现有技术中的动臂锁定装置容易因颠簸、振动而失效的问题。
