The invention discloses a sliding and rotating type counterweight system which comprises a sliding and rotating device and a counterweight block, the counterweight block is assembled on the sliding and rotating device, and the counterweight block is driven to move through simultaneous sliding and rotating movement of a base on a support, so that the gyration radius and the gravity center position of a counterweight are changed. And a larger displacement distance is realized. Meanwhile, the invention discloses a using method of the balancing weight system. The gravity center position and the turning radius of the balancing weight are variable, and the larger displacement distance of the balancing weight is achieved; under the same condition, the weight of the balancing weight is reduced, the crane turning radius is reduced, the system reliability is improved, and narrow space operation is adapted.
本发明公开了一种滑动旋转式平衡重系统,包括滑动旋转装置与平衡重块,平衡重块装配在滑动旋转装置上,通过底座在支架上同时进行滑动和旋转运动进而带动平衡重块运动,从而改变平衡重的回转半径及重心位置,实现更大的变位距离。同时公开了该平衡重系统的使用方法。本发明实现平衡重重心位置和回转半径可变,实现平衡重更大的变位距离;在同等条件下减少平衡重重量,减小起重机回转半径,提高系统可靠性,适应狭小空间作业。
