The invention provides a counterweight-free elevator traction device, and belongs to the technical field of elevators. The counterweight-free elevator traction device comprises a multi-layer elevator frame and a steel belt. A driving device is installed at the top end of the multi-layer elevator frame, a car is arranged in the multi-layer elevator frame, a first pulley and a second pulley are installed at the top end and the bottom end of the car, a third pulley is installed at the bottom in the multi-layer elevator frame, one end of the steel belt is connected with the top end of the multi-layer elevator frame, and the other end of the steel belt is connected with the other end of the multi-layer elevator frame. And then the other end of the steel belt sequentially bypasses the first pulley, the driving device, one third pulley, the second pulley and the other third pulley and is connected with one side of the bottom end of the multi-layer elevator frame. Through the arrangement of the steel belt, the distance between the lift car wall and the multi-layer elevator frame is very small, the lift car can be made to be maximum as much as possible under the hoistway with the same size, and carrying personnel are increased.
本申请提供了一种无对重电梯牵引装置,属于电梯技术领域。该无对重电梯牵引装置,包括多层电梯框架和钢带。所述多层电梯框架顶端安装有驱动装置,所述多层电梯框架内部设置有轿厢,所述轿厢顶端和底端均安装有第一滑轮和第二滑轮,且所述多层电梯框架内底部安装有第三滑轮,所述钢带一端与所述多层电梯框架顶端连接,然后所述钢带另一端依次绕过所述第一滑轮、所述驱动装置、一个所述第三滑轮、所述第二滑轮和另一个所述第三滑轮并与所述多层电梯框架底端一侧连接。通过钢带的设置,使得轿厢壁与多层电梯框架的距离非常小,在同尺寸的井道下,能够把轿厢尽可能的做得最大,增加运载人员。
