The invention belongs to the field of crane accessories, and particularly relates to a gravity center lifting crane anti-sway device. The gravity center lifting crane anti-sway device includes a support frame, a lifting mechanism, a running trolley and a sling; an anti-sway frame is arranged under the running trolley; the upper end of the sling is fixedly connected to the inner top surface of theanti-sway frame; two L-shaped connecting rods are fixedly connected to the lower end of the running trolley; a fixed wheel disc is fixedly installed between the two L-shaped connecting rods; the fixedwheel disc is located in the anti-sway frame and arranged in parallel with the anti-sway frame; a rotating ring is rotatably connected to the side wall of the outer ring of the fixed wheel disc; thelower end of the rotating ring is provided with a segment of tooth groove; a rack is fixedly connected to the outside of the sling; the rack meshes with the lower end of the rotating ring; and both sides of the rotating ring are provided with ratchet teeth. The gravity center lifting crane anti-sway device can convert the kinetic energy and inertial potential energy of a weight swinging upward dueto inertia and wind into gravitational potential energy, so that the swinging energy is quickly converted and consumed, and a good anti-sway effect is realized.
本发明属于起重机配件领域,尤其是涉及一种重心提升式起重机减摇装置,包括支撑架、抬升机构、运行小车和吊索,所述运行小车的下方设有减摇框体,所述吊索的上端与减摇框体的内顶面固定连接,所述运行小车的下端固定连接有两根L形连接杆,两根所述L形连接杆之间固定安装有固定轮盘,所述固定轮盘位于减摇框体内并与减摇框体平行设置,所述固定轮盘的外圈侧壁上转动连接有转动环,所述转动环的下端设有一段齿槽,所述吊索外固定连接有齿条,所述齿条与转动环的下端啮合,所述转动环的两侧设有棘齿。本发明可将重物因惯性和风力向上摆动的动能和惯性势能转化为重力势能,从而使其摆动的能量被快速转化消耗,实现了良好的减摇效果。
