The invention discloses a dual-drive elevator, and relates to the technical field of elevators. The dual-drive elevator comprises a hoistway and a lift car, wherein the hoistway is in sliding connection with the lift car, a first traction machine and a second traction machine are installed at the top of the hoistway, one end of the first traction machine and one end of the second traction machine are connected with a balance weight B and a balance weight A through steel wire ropes correspondingly, and the other end of the first traction machine and the other end of the second traction machine are connected with bridge top wheels and bridge bottom wheels through steel wire ropes correspondingly. Two sets of driving systems are arranged and stacked, so that the first traction machine and the second traction machine can be changed into smaller specifications, the technical difficulty of traction machine development is reduced, the first traction machine and the second traction machine are connected with the lift car through the steel wire ropes, the two sets of driving systems do not interfere with each other during use and are completely independent, the balance of the lift car can be kept, the technical difficulty of synchronous control of the two sets of driving systems is greatly reduced, and the running safety of the elevator can be better guaranteed.
本发明公开了一种双驱动电梯,涉及电梯技术领域,包括井道、轿厢,所述井道与轿厢之间滑动连接,所述井道的顶部分别安装有第一曳引机与第二曳引机,所述第一曳引机与第二曳引机的一端分别通过钢丝绳连接有配重B与配重A,且第一曳引机与第二曳引机的另一端分别通过钢丝绳连接有桥顶轮与桥底轮。本发明通过设置有两套驱动系统,使其叠加,即使得第一曳引机与第二曳引机可以改用更小规格,降低了曳引机开发的技术难度,且通过第一曳引机与第二曳引机分别通过钢丝绳与轿厢连接,其两套驱动系统使用时互不干扰,完全独立,并都可以保持轿厢的平衡性,大幅度降低了两套驱动系统同步性控制的技术难度,可更好地保障电梯运行的安全性。
