Elevator no-load balance coefficient detection device

The utility model provides an elevator no-load balance coefficient detection device. The elevator no-load balance coefficient detection device comprises an upper clamp, a hydraulic cylinder assembly, a lower clamp and a tension sensor. The upper clamp is arranged above the hydraulic cylinder assembly and used for clamping the upper portion of a selected hoist rope section. The hydraulic cylinder assembly is used for lifting the lower clamp. The lower clamp is arranged below the hydraulic cylinder assembly and used for clamping the lower portion of the selected hoist rope section. The tension sensor is used for measuring the tension of the hydraulic cylinder assembly. The hydraulic cylinder assembly serves as a load measuring device, the characteristics of the working stability and reliability of the hydraulic cylinder assembly are fully used, and therefore the elevator no-load balance coefficient detection device has the advantages of being easy to operate, safe in operation process and high in performance, and meanwhile the measured data obtained through the hydraulic cylinder assembly are higher in accuracy.
