A displacement counterweight mechanism relates to the field of engineering machinery and is characterized in that a primary telescopic mechanism is arranged on the lower portion of a counterweight support, one end of a swing support is connected with the primary telescopic mechanism, the other end of the swing support is connected with a counterweight bracket, and a counterweight block is placed on the counterweight bracket; the first-stage telescopic mechanism moves to drive the swing support to swing, the swing support drives the balance weight bracket to move together, and the balance weight block is placed on the balance weight bracket, so that the rotation radius and the gravity center position of the balance weight are changed; furthermore, a second-stage telescopic device can be additionally arranged between the counterweight bracket and the swinging bracket, and the counterweight bracket is driven to further swing through the movement of the second-stage telescopic device, so that a larger displacement distance is realized; the technical problem that the displacement distance of the balancing weight is limited is solved, and the tipping performance of the crane is further improved; and the problem that the counterweight bracket is time-consuming and labor-consuming to disassemble and assemble in a transition state is solved, the efficiency is improved, and the cost is saved.
一种变位平衡重机构,涉及工程机械领域,所述的一级伸缩机构设置在平衡重支架的下部,摆动支架的一端与一级伸缩机构连接,摆动支架另一端与平衡重托架连接,平衡重块放置在平衡重托架上;本发明通过一级伸缩机构运动带动摆动支架摆动,摆动支架带动平衡重托架一起运动,平衡重块放置在平衡重托架上,从而改变平衡重回转半径及重心位置;进一步的,可以在平衡重托架与摆动支架之间增加二级伸缩装置,通过二级伸缩装置运动带动平衡重托架进一步摆动,实现更大的变位距离;本发明解决了平衡重变位距离有限的技术使问题,起重机倾翻性能得以进一步提升;也解决了转场状态下平衡重支架拆装费时费力的问题,提高了效率,节约了成本。
