The invention relates to the technical field of hoisting equipment, in particular to a double-multiplying-power eight-rope grab bucket hoisting trolley. The double-multiplying-power eight-rope grab bucket hoisting trolley comprises a trolley frame and a double-multiplying-power eight-rope grab bucket hoisting tool, one side of the top of the trolley frame is connected with a hoisting mechanism through bolts, one side or two sides, close to the hoisting mechanism, of the top of the trolley frame are connected with a brake for the hoisting mechanism through the bolts, one side, away from the brake for the hoisting mechanism, of the top of the trolley frame is connected with an opening and closing mechanism through the bolts, and an opening and closing winding drum is arranged on the outer side of the opening and closing mechanism. The double-multiplying-power eight-rope grab bucket hoisting trolley has the beneficial effects that steel wire ropes of the hoisting mechanism and the openingand closing mechanism are connected in parallel in a wound mode, the two steel wire ropes of the opening and closing mechanism enter from a rope guide hole above a double-multiplying-power eight-ropegrab bucket hoisting tool and then are wound out from the two sides to return to the trolley frame to be fixed, the mode depends on the mutual traction force of the steel wire rope arrangement mode,the anti-swing and anti-deflection functions of the hoisting tool are achieved through the winding method of rope winding, the flexibility of the hoisting trolley is higher, the load torque of the hoisting mechanism and the opening and closing mechanism is halved, and the manufacturing costs of the hoisting mechanism and the opening and closing mechanism are reduced.

    本发明涉及吊运设备技术领域,具体是二倍率八绳抓斗起重小车,包括小车架与二倍率八绳抓斗吊具,小车架顶部的一侧通过螺栓连接有起升机构,小车架顶部靠近起升机构的一侧或两侧通过螺栓连接有起升机构用制动器,小车架顶部远离起升机构用制动器的一侧通过螺栓连接有开闭机构,开闭机构的外部设置有开闭卷筒。本发明的有益效果为起升和开闭的机构钢丝绳平行绕接,开闭机构的两根钢丝绳从二倍率八绳抓斗吊具上方的导绳孔进入,然后分两边绕出回到小车架上固定,此种方式靠钢丝绳布置的方式的相互牵制力,通过绳系的绕法实现吊具防摇防偏摆功能,起重小车的灵活性更强,起升和开闭机构的负载转矩减半,降低起升和开闭机构的制作成本。
