Embodiment Construction

[0018] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0019] Such as Figure 1~2 As shown, the elliptical sleeve type steel wire rope tension detection device of the present invention comprises two symmetrically fastened and pressed arc-shaped tension sensing plates 7 on both sides of the steel wire rope 1 with side wings, and the arc-shaped tension sensing plates 7 have a carbon content of 0.5% to 0.8% carbon steel. The side wings of the arc-shaped tension sensing plate 7 are fixedly connected by the internal fastening bolts 5, and the inner walls of the two buckled arc-shaped tension sensing plates 7 form an elliptical cylinder, and the length of the minor axis of the elliptical cylinder is 90% of the diameter of the steel wire rope 1 ~95%, the length of the major axis of the oval cylinder is 140%~150% of the diameter of the steel wire rope 1. 6-10 resistance strain gauges 6 are pasted along the central ax...

Abstract

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.

Description

technical field [0001] The invention relates to an elliptical sleeve type steel wire rope tension detection device and method, which is especially suitable for tension detection of round strand steel wire ropes. Background technique [0002] As a key component of hoisting, traction, and load-bearing mechanisms, wire ropes are widely used in mine hoisting, bridge suspension, aerial ropeways, etc., and their tension directly reflects the operating status of the equipment. At present, the steel wire rope tension detection mainly adopts the following three methods: one is the direct detection method of connecting the sensor in series with the steel wire rope; the other is the indirect detection method of using the three-point bending method to detect the lateral force of the steel wire rope; Oscillatory wave method for relationship between wave propagation velocities. The rope tension measuring device whose publication number is CN 200810185697.9 uses a three-point bending meth...
