The working principle of synchronous lifting jack is based on hydraulic transmission and synchronous coordination mechanism. In the hydraulic transmission process, the hydraulic pump pressurizes the hydraulic oil and transmits it to the hydraulic cylinder of the jack. In the hydraulic cylinder, the hydraulic oil exerts force on the piston, pushing the piston to move up along the cylinder, driving the ejector rod to lift the weight. The synchronous coordination mechanism is realized by intelligent control system and multiple high-precision sensors. Sensors are located throughout the jack to collect data such as position change, speed, pressure and so on. After the data is transmitted to the control system, the control system will adjust the hydraulic oil supply parameters of each jack to precisely control the flow and pressure of the hydraulic oil, so that the lifting action of each jack can be synchronized if it is found that the lifting is not synchronized between the jacks. This principle is widely used in the overall structure upgrading of large construction projects, the installation of heavy industrial equipment and other fields, ensuring the efficiency and safety of engineering operations.
(1) The structure of the new support should meet the design requirements and relevant industry regulations.
(2) The overall replacement of the support construction scheme should be calculated to determine the batch of replacement of the support, the displacement of the top and falling beams and the process.
(3) The temporary support of the lifting beam body should meet the requirements of strength, stiffness and stability.
(4) The lifting and falling of the beam should be carried out according to the design requirements.
(5) When the support is replaced, the deviation of the support should be checked according to the ambient temperature, and the construction should be selected under favorable temperature conditions.
(6) Measure the height difference between the original support and the new support, and adjust the construction to ensure that the beam body and bridge floor elevation meet the reinforcement design requirements. Richard
