Dynamic measuring method of wire rope tension

Abstract

The invention discloses a dynamic measuring method of wire rope tension. Eight pressure sensors are uniformly arranged in the peripheral direction of the interior of a liner of a score of a roller ofan elevator, as the roller rotates, the eight pressure sensors can measure pressure values at different locations, a tension signal of a wire rope is obtained through the pressure of the wire rope onthe liner. Leads of the pressure sensors are introduced into the interior of the roller of the elevator through a special hollow bolt on the roller, a signal conditioning circuit and a signal acquisition transmitting device are installed on a spoke plate in the roller, and signals of the pressure sensors of the liner are transmitted to an upper computer wirelessly. According to the dynamic measuring method of wire rope tension, a pressure signal can be converted into the tension signal of the wire rope through the special relationship between the liner pressure and the wire rope tension, the method is convenient to install, safe, reliable and convenient to maintain, unstable factors of transmission of the signals inside a mine are avoided, and the security and practicality are greatly improved.

Description

technical field [0001] The invention relates to a dynamic measurement method, in particular to a novel steel wire rope tension dynamic measurement method, which belongs to the technical field of steel wire rope tension monitoring. Background technique [0002] With the development of social science and technology, people's awareness and requirements for safety are getting higher and higher. Due to the limitation of the special working environment and production conditions of the mine, the research on the dynamic measurement of the wire rope tension of the hoist at home and abroad in recent years is mainly to measure the tension of the wire rope on the hydraulic device connected between the wire rope and the skip, but due to the signal transmission inside the mine Unstable factors have not yet made a huge breakthrough, it is difficult to apply in practice, and it is impossible to implement effective monitoring of the upgrading project. Therefore, improvement is needed to pro...
