介绍了一种曳引式节能电梯设计方案。在保持电梯原有曳引结构系统不变的基础上,增加机械变速器、辅助配重、卷筒等装置,使机械变速器输入端连接电梯曳引轮,输出端通过卷筒连接辅助配重。采用机械变速器改变辅助配重与轿厢运动的速比可以匹配电梯不同的载重量与起升高度,实现配重可调,进而可以补偿曳引轮两侧的重量差,使曳引电机维持在低能耗状态。该设计方案利用辅助配重势能的改变就能够实现负载势能的储存和释放,能量形式没有发生转变,是一种直接的节能方案。
Introduced a traction energy-saving elevator design. On the basis of maintaining the same original traction structure system of the elevator, adding mechanical transmission, auxiliary counterweight, drum and other devices to connect the input end of the mechanical transmission to the elevator traction sheave and the output end to connect the auxiliary counterweight through the reel. The use of a mechanical transmission to change the speed ratio of the auxiliary counterweight and the car motion can match the different load and lifting height of the elevator so as to realize the adjustable counterweight so as to compensate the weight difference between both sides of the traction sheave and maintain the traction motor at Low energy state. The design scheme utilizes the change of the auxiliary counter-balance potential energy to realize the storage and release of the load potential energy, and the energy form has not changed, which is a direct energy-saving solution.
