The invention discloses a hydraulic control wedge-shaped cylinder pin locking device and method and a crane. The hydraulic control wedge-shaped cylinder pin locking device comprises a cylinder pin base, a cylinder pin, a first spring, a push rod base, a second spring, a push rod and a wedge-shaped block. The cylinder pin is connected with the cylinder pin seat; the first spring is arranged in the cylinder pin seat and used for driving the cylinder pin seat to drive the cylinder pin to move; a cavity is formed in the cylinder pin seat, and an oil inlet and a through opening are formed in the cavity; the push rod base covers the oil inlet; one end of the second spring is connected with the push rod base, and the other end of the second spring is connected with the cylinder pin seat; the wedge-shaped block is in sliding connection with the side wall of the cylinder pin; the push rod and the second spring are coaxially arranged, one end of the push rod is connected with the push rod base, and the other end of the push rod penetrates through the through opening and then is connected with the wedge-shaped block to drive the wedge-shaped block to move into the cylinder pin hole along the side wall of the cylinder pin. The gap between the cylinder pin and the cylinder pin hole reserved for improving the success rate of inserting the cylinder pin can be compensated, and finally the purposes of reducing telescopic arm shaking generated when the telescopic oil cylinder drives the telescopic arm to retract and eliminating abnormal sound caused by collision between the cylinder pin and the telescopic arm are achieved.

    本发明公开了一种液控楔形缸销锁紧装置、方法及起重机,包括缸销座、缸销、第一弹簧、推杆底座、第二弹簧、推杆和楔形块;缸销与缸销座相连;第一弹簧设于缸销座内,用于驱动缸销座带动缸销运动;缸销座上设有空腔,空腔上设有进油口和贯通口;推杆底座覆盖在进油口上;第二弹簧设于空腔内,一端与推杆底座相连,另一端与缸销座相连;楔形块与缸销的侧壁滑动相连;推杆与第二弹簧同轴设置,一端与推杆底座相连,另一端穿过贯通口后与楔形块相连,驱动楔形块沿着缸销的侧壁运动至缸销孔内。本发明能够补偿为提高插缸销成功率而留出的缸销与缸销孔之间的间隙,最终达到减少伸缩油缸带动伸臂缩回时产生的伸臂抖动和消除缸销与伸臂碰撞带来的异响。
