Incremental Launching and Closure Control System and Dampers

Introduction

The Incremental Launching Closure Control System and Damper is suitable for the closure of long-span, large-displacement, and heavy-tonnage bridges. It possesses both the vibration damping and seismic resistance functions of ordinary dampers and the jacking function of ordinary hydraulic jacks. Simultaneously, it features displacement compensation and locking capabilities that are absent in both wire rope tensioning and conventional jacking methods, enabling all-weather and intelligent precise closure.

Advantages

1.All-Weather Closure: The device adjusts based on the distance at the closure joint, consistently maintaining an unchanged joint gap. It can automatically perform temperature compensation, achieving all-weather closure.
2.High Precision Grade: Compared to the manual control of ordinary hydraulic cylinder jacking, this device utilizes servo control, allowing operational precision to be controlled within millimeter-level accuracy.
3.Convenient Installation: Compared to ordinary dampers, this device requires no manual length adjustment. Compared to ordinary hydraulic cylinder jacking, it avoids secondary disassembly and reinstallation and is unaffected by the magnitude of jacking force or displacement.
4.High Degree of Automation: Equipped with functions such as automatic jacking and deviation correction. It only requires inputting the set displacement to operate automatically while continuously maintaining the closure joint distance. It can simultaneously perform jacking and stretching and possesses a locking function.
