Abstract

The invention relates to a multi-rope winder steel wire rope tension test method and a device thereof. The method comprises the following steps: firstly fixing an acceleration transducer on steel wire ropes to be tested and connecting with a tension measuring device, then beating the steel wire ropes vertically to generate transverse vibration, collecting the diffusion cycle t of the vibration wave on the steel wire ropes by the acceleration transducer, then inputting the steel wire rope length L, steel wire rope density rho and correction coefficient beta in the tension measuring device of the steel wire ropes to obtain the terminal load Qi of each steel wire rope, and then inputting the average load Qp, diameter R, elastic modulus Ep and the measured terminal load Qi of the steel wire ropes in a tension analysis system to calculate the rate of deviation Pi and adjustment value Delta Li of each steel wire rope. The method and device of the invention can accurately measure the tension of the steel wire rope and analyze the degree of uniformity between a plurality of steel wire ropes to obtain the adjustment value and manage and maintain the steel wire rope, thus prolonging the service life of the steel wire rope, preventing accidents to happen and having an important use value.

Description

technical field [0001] The invention relates to a method for detecting the tension of a steel wire rope and a detection device thereof, in particular to a method for detecting the tension of a steel wire rope of a multi-rope hoist for mining equipment and a detection device thereof. Background technique [0002] The multi-rope hoist is a common equipment in the industry. The uniformity of the tension on the wire rope is an important indicator for the use of the wire rope. According to relevant regulations, the difference between the tension value of each rope of the multi-rope hoist and its average value shall not exceed 10%. [0003] Existing detection methods for wire rope tension mainly include: one is to connect a load cell in series between the wire rope and the lifting weight to measure, this method must be measured in a static state of the wire rope, and the operation process is relatively complicated and the sensitivity is low Another kind is to adopt three-point ben...
