The invention discloses a movable supporting leg self-locking device and method for a wheeled crane and the wheeled crane, and the self-locking device comprises a limiting device used for limiting a movable supporting leg when the movable supporting leg of the wheeled crane moves to a designated position; the warping plate is used for controlling the limiting state of the limiting device; the locking mechanism is used for driving the warping plate to move up and down; and the triggering mechanism is used for abutting against the locking mechanism when moving to a designated position along with the movable supporting leg, and the triggering mechanism is used for triggering the locking mechanism to act. By means of the triggering mechanism, the limiting device and the warping plate, automatic locking when the movable supporting leg stretches and retracts to the designated position is achieved, potential safety hazards possibly caused by human reasons are avoided, and the safety of a vehicle is enhanced.

    本发明公开了一种轮式起重机用活动支腿自锁装置、方法及轮式起重机,该自锁装置包括:限位装置,用于轮式起重机活动支腿运动到指定位置时,对活动支腿进行限位;翘板,用于控制所述限位装置的限位状态;锁止机构,用于驱动所述翘板上下移动;触发机构,用于随活动支腿运动到指定位置时,与所述锁止机构相抵,所述触发机构用于触发所述锁止机构动作。本发明利用触发机构、限位装置及翘板,实现了活动支腿伸、缩到指定位置时的自动锁止,避免了由于人为原因可能导致的安全隐患,增强了车辆的安全性。
