The invention provides an elevator no-load balance coefficient detection device based on screw pulling-up, comprising an upper clamp, a lower clamp, a trapezoidal screw, a trapezoidal nut, and a force transducer. The upper clamp is used for clamping the upper part of a selected traction rope. The lower clamp is used for clamping the lower part of the selected traction rope. The trapezoidal screw can sleeve the upper clamp in an up-down movement mode. The trapezoidal nut sleeves the trapezoidal screw, and is disposed above the upper clamp. The force transducer is mounted between the trapezoidal screw and the lower clamp, and is used for measuring the pulling force between the trapezoidal screw and the lower clamp. According to the invention, a lifting device is replaced by a screw pulling-up device. In the use process, the screw pulling-up device can solve the problem that a hydraulic system load measuring device is of poor synchronization performance. Through use of the screw pulling-up device, the overall cost, overall size and overall weight are reduced.
