Bridge Construction Tensioning System

The components and working principle of intelligent tensioning equipment
The system is composed of a computer or industrial computer, PLC, analog conversion module, sensor, power box, oil pump, oil tank, pressure gauge, chassis shell, jack, high-pressure oil pipe, and other parts. The prestress tension program control system takes the tension as the control index and the elongation error as the proofreading index.
The system collects data such as the working pressure of each tensioning device (jack) and the elongation (including retraction) of the steel strand through sensor induction measurement, and transmits the data to the system computer in real time for calculation and judgment, and then returns the data Pass it to the PLC to adjust the working parameters of the oil pump motor at any time to control the amount of oil output to obtain the required pressure value, thereby achieving precise control of high-precision tension and loading speed.
