The invention discloses a device and a method for detecting the tension of an elliptic sleeve type steel
wire rope. The device comprises two arc tension sensing plates which are symmetrically buckled on the two sides of the steel
wire rope, wherein a plurality of resistance strain sheets are arranged at intervals on the contact surfaces between the arc tension sensing plates and the steel
wire rope; hollow cylindrical clamping covers with side wings are arranged on the outer parts of the arc tension sensing plates; the upper parts and the lower parts of the hollow cylindrical clamping covers are buckled on the steel wire
rope; rubber cushions are arranged at the places, where the hollow cylindrical clamping covers are buckled with the steel wire
rope; the side wings of one hollow cylindrical clamping cover and the side wings of the other hollow cylindrical clamping cover are fixedly connected together through outer fastening bolts; and
signal processors are arranged at the bottoms on the inner sides of the hollow cylindrical clamping covers. The output
voltage change of the resistance strain sheets is detected through the
signal processor by means of the radial contraction and the expansion change of the arc tension sensing plates, the tension change of the steel wire
rope is calculated, the tension data of the steel wire rope is sent to an industrial
personal computer through the
signal processors, and then the tension of the steel wire rope is detected. The device is simple in structure, high in detection efficiency and high in detection speed, and is convenient to operate.
