Problems solved by technology
Manual adjustment is based on experience, it is difficult to ensure that the tension of each steel wire or rope strand is consistent after adjustment
And because it is impossible to adjust in real time, it is impossible to ensure that the tension of each steel wire or strand is always balanced and consistent
It is inevitable that the appearance of the produced steel wire rope will have "edges", "waves" and other phenomena, which will cause certain safety hazards in the twisted steel wire rope, and the service life will also be affected

The invention relates to an online measuring device, a measurement and control system and a measurement and control method for tension of a stranding machine. A guide wheel is mounted at the top of each of two vertical columns of the measuring device, a pressure and tension sensor is mounted in a spring seat on a bottom plate, a spring is connected with the pressure and tension sensor, the upper end of the spring is connected with a vertical shaft which penetrates through a cross beam, and an adjusting wheel is mounted at the top end of the vertical shaft. A displacement sensor is mounted on the vertical shaft, a steel wire of a pay-off wheel strides across one guide wheel, bypasses the adjusting wheel and then strides across the other guide wheel to be connected into the stranding machine, and the two sensors are connected with the computer wirelessly. The measurement and control system comprises the computer and a plurality of the online tension measuring devices mounted on steel wires respectively, the two sensors of each online tension measuring device are connected with the computer, and a control terminal of the computer is connected with each pay-off wheel damper to control pay-off speed. The measurement and control method includes: setting a tension value, acquiring displacement tension data of each measuring device, computing current tension of each steel wire, and comparing the current tension with the set tension to obtain control quantity of the pay-off wheel dampers. The online measuring device, the measurement and control system and the measurement and control method for tension of the stranding machine have the advantages that real-time online tension measurement and control of the steel wires can be realized, tension constancy is controlled automatically, and stranding quality is guaranteed.
Description
technical field [0001] The invention relates to a steel wire rope production machine, in particular to an on-line tension measuring device, a measurement and control system and a measurement and control method for a twisting machine. Background technique [0002] Steel wire rope has high strength, good elasticity, light weight, and good flexibility. It is an important component widely used in various industries such as machinery, shipbuilding, mining, metallurgy, and forestry. A steel wire rope is a rope made of twisted steel wires. Multiple steel wires are twisted into rope strands, and multiple strands are twisted around the central rope core to form a steel wire rope. In order to ensure the safety and reliability of the steel wire rope, the steel wire rope is required to have sufficient strength, good flexibility, compactness of twisting, compression resistance, wear resistance, corrosion resistance and fatigue resistance, among which strength is the most important . ...
