The invention discloses an energy-saving freight elevator traction system. The traction ratio of the traction system is 4: 1, and the traction system comprises a traction rack, a traction machine, a counterweight frame and a traction rope; and the traction rack comprises a bearing beam and a main machine frame installed on the bearing beam. The main machine frame comprises a first frame, a second frame, a third frame and a fourth frame which are sequentially connected end to end, the traction machine is installed on the first frame and connected with a traction sheave, a counterweight guide wheel is arranged on the second frame, the axis of the counterweight guide wheel is perpendicular to the axis of the traction sheave, and a counterweight rope hitch plate is arranged on the third frame. A counterweight diversion sheave assembly is installed in the middle of an upper beam of the counterweight frame and comprises two counterweight diversion sheaves which are coaxial, the axes of the counterweight diversion sheaves are parallel to the horizontal center line of the counterweight frame, and the axes of the counterweight diversion sheaves are parallel to the axis of the traction sheave. According to the energy-saving type freight elevator traction system, the length size of the counterweight frame is effectively reduced, and therefore the requirement for the depth of a hoistway is lowered.

    本发明公开了一种节能型载货电梯曳引系统,曳引系统的曳引比为4:1,其包括曳引机架、曳引机、对重架和曳引绳;曳引机架包括承重梁和安装于承重梁的主机架;主机架包括首尾依次连接的第一边框、第二边框、第三边框和第四边框,曳引机安装于第一边框,曳引机连接有曳引轮,第二边框上设有对重导向轮,对重导向轮的轴线垂直于曳引轮的轴线,第三边框上设有对重绳头板;对重架的上梁中间位置安装有对重反绳轮组件,对重反绳轮组件包括两个共轴线的对重反绳轮,对重反绳轮的轴线平行于对重架的水平中心线,且对重反绳轮的轴线平行于曳引轮的轴线。本发明一种节能型载货电梯曳引系统,有效缩小了对重架的长度尺寸,从而较低了对井道深度的要求。
