Large tonnage jack fully automatic intelligent tensioning equipment intelligent tensioning box system

Intelligent tensioning refers to the use of computer intelligent control technology, without relying on manual control by workers, to complete the tensioning construction of steel strands through automatic operation of instruments. In today's bridge and road construction,prestressConstruction is widely used

The intelligent tensioning control system is used for automatic control of bridge prestressed tensioning, using a highly integrated controller that controls synchronous tensioning of two or four cylinders through electromagnetic valves. The system operation is simple, and the entire tensioning process can be completed with just one click. The control accuracy is high, which can effectively improveQuality of prestressed construction.

System characteristics

1One machine controlled double top

A smart tensioning master or slave can control up to two jacks. When tensioning with dual beam and four cylinders, only two machines are needed, reducing costs and making it easy to use.

2Advanced control algorithms with high control accuracy and accurate synchronization

Based on a comprehensive mathematical model, advanced control algorithms are used to control tension, ensuring accurate tension and synchronization between jacks.

3Adopting dedicated integrated controller, reliable and durable

The core controller adopts an integrated controller designed specifically for bridge tensioning, with high reliability and easy maintenance. The controller adopts a color LCD display and dedicated physical button control. Compared to using control methods such as laptops and touch screens, this controller is more practical and easy to operate.

Process flow of prestressed tensioning: steel strand threading → installation of work anchor → installation of supporting limit plate → installation of jack → installation of supporting tool anchor → symmetrical tensioning at both ends → tensioning force 15% → tensioning force 30% → tensioning force 100% → tensioning force 103% → holding load for 2 minutes for anchoring → after checking the elongation value and passing it, proceed to the next bundle tensioning → tensioning operation is completed.

The traditional tensioning machine equipment uses manual operation to operate multiple handles of the high-pressure combination valve to achieve various beam types of pre-stressed tensioning, load holding time control, and load compensation operations. There are complex operating procedures, and the prestressing tension value is generally insufficient due to human factors, resulting in a high rate of misoperation; A series of issues such as not recording the actual tensioning results and not recording truthfully. The CNC equipment achieves precise automatic control of prestress during the process of prestress tensioning. And can automatically collect the tensioned prestress; Set the tensioning form (segmented tensioning); Automatically record tensioning time, shifts, and each bundlePrestressed reinforcementThe final pre-stress value and other parameters after tensioning are transmitted through wireless remote data transmission, and these values are formed into reports on the upper computer, saved or printed out. Ensure the accuracy and authenticity of tensioning quality and records.
