The frequency conversion synchronous lifting system developed by Jiangsu Canete is used in the settlement and deformation repair projects of high-speed and ordinary railways, urban tracks, underground works, dams, bridges, tunnels, building structures, petroleum and municipal pipelines. In this paper, we This paper mainly introduces a specific case of synchronous lifting of high-speed rail pile foundation settlement and the necessary tools for its realization.
The biggest safety point in the operation of high-speed railways is that the roads in high-speed railways should use straight lines or large-radius circular curves as much as possible, and the lines should not have too much settlement. Important facilities such as national high-speed railways and urban rail transit will have pile foundation settlement monitoring and early warning. Once a problem is found, it should be solved immediately.
The length of the Beijing-Shanghai high-speed railway Tianjin section bridge is 113.69 kilometers. It starts from Langfang City, Hebei Province in the north, passes through Wuqing, Xiqing and other districts in Tianjin City, and ends in Qingxian County, Cangzhou City, Hebei Province. Because the whole line is a flyover, it is under construction. The staff is called "Bridge King". According to the settlement monitoring report, the maximum accumulated settlement of this section is 142.8mm. For this purpose, it is necessary to Remediate differential settlement and ease the safety of driving and equipment.

Two frequency conversion synchronous lifting hydraulic systems control the synchronous lifting of the beam
The control accuracy of the frequency conversion control synchronous lifting system is less than ±0.2mm. It can be extended to 32 points or more than 32 points of multi-point synchronization on the basis of two-point synchronous lifting, up to 99 points. In the multi-point synchronization working state, In addition to maintaining the synchronization of multi-point positions, the load distribution of each fulcrum can be adjusted according to the user's requirements. The dual control of force synchronization and displacement synchronization can be realized, and it can be automatically called at different stages. Multiple hydraulic valves and intelligent programs ensure that the lifting and data are consistent. Safety. Through the process protection function of the flat load valve, the common cylinder expansion accident during multi-cylinder lifting is avoided.
As a manufacturer of PLC controlled synchronous lifting system, Jiangsu Caneteprovides lifting equipment and technical support for hundreds of bridge synchronous lifting projects in China. The company has strong strength, mature technology and industry leader, and is committed to providing hydraulic Synchronized lifting solution.
