Hoisting mechanism used for grab machine and grab machine
The invention discloses a hoisting mechanism used for a grab machine and the grab machine with the hoisting mechanism. The hoisting mechanism comprises a spindle and rotatable winding drums arranged at the two ends of the spindle in a sleeving manner correspondingly. A rope used for being connected with at least one grab bucket is wound on each winding drum. The rope outlet directions of the ropeson the two winding drums are opposite. By means of the above structure, when the two winding drums work in a linked manner, due to the fact that the rope outlet directions of the ropes on the two winding drums are opposite, the two grab buckets work at the same time in a manner that one grab bucket ascends and the other grab bucket descends, the two grab buckets cooperatively work, the efficiencyis doubled, construction time is greatly saved, the potential energy of the descending grab bucket is fully utilized for providing kinetic energy for the ascending grab bucket, the grab buckets serveas balance weights of each other, energy consumption generated when the grab buckets ascend and descend is reduced more effectively, and the energy utilization rate of a grab bucket system is higher.
本发明公开了一种用于抓斗机的卷扬机构及具有该卷扬机构的抓斗机，包括主轴及分别套设于主轴两端的可旋转的卷筒，每个卷筒上缠绕有用于连接至少一个抓斗的绳索，两个所述卷筒上的绳索的出绳方向相反。藉由上述结构，两个卷筒联动工作时，由于两个卷筒上的绳索的出绳方向相反，两个抓斗一升一降同时工作，双抓斗协同作业效率双倍提升，大大节约了施工时间，且充分利用下降抓斗的势能为上升抓斗提供动能，互为配重更有效降低了抓斗升降时的能耗，抓斗系统的能量利用率更高。
