Synchronous jacking is a special testing instrument used in the field of mechanics, especially playing an important role in bridge maintenance, inspection and reconstruction. This technology can achieve uniform lifting of the entire bridge or other structures through multi-point lifting and high-precision control systems, and ensure the safety and efficiency of operations.
The synchronous jacking system is usually composed of an electric motor, a high-pressure hydraulic pump, a fuel tank, an operation control system, a jack, a pipe, a diverter, etc. The flow of a pump station is output through a diverter and provided to each actuator cylinder respectively. The displacement control system controls the speed of the loaded jacking of each cylinder according to the feedback signal of each different measuring point, thereby realizing the synchronous jacking action of the entire structure.
The technical indicators of the synchronous jacking system include the ability to control multi-point synchronization, the ability to connect multiple synchronous sub-controllers, the ability to achieve overall and single-point local lifting respectively, and high hydraulic synchronization accuracy. In addition, it also has a variety of functions, such as weighing large and heavy objects, synchronous jacking for moving, jacking and lowering of heavy equipment during installation and maintenance, jacking and replacement of rubber bearings for highway bridge repair and reinforcement, jacking and translation of buildings, etc.
In bridge engineering, the use of synchronous jacking technology can improve work efficiency, ensure work safety, and reduce damage to bridge structures. With the continuous development of science and technology, synchronous jacking technology will be further improved and widely used in bridge and other structural engineering fields.
