Synchronous lifting jacks
intro
1. Synchronous lifting jack is a new type of large component lifting equipment, mainly composed of lifting jack, hydraulic pump station, control system. The principle is to integrate the prestressed anchor anchoring technology with the hydraulic jack technology, anchor the steel strand through the anchor, and then use the computer to centrally control the output flow and oil pressure of the hydraulic pump station, drive the lifting jack piston to extend and shrink, drive the steel strand and the component to lift and fall, so as to achieve the overall synchronous lifting and falling of large components.
2.PLC more synchronous hydraulic system is divided into five parts: hydraulic pump. PLC electronic computer automatic control system. Hydraulic systems. Displacement pressure detection and industrial touch screen computer operating systems. Synchronous lifting The system is the hydraulic lifting system. Electronic computer PLC signal analysis. Displacement monitoring and beam bridge analysis are integrated with construction technology, and complete equipment development is carried out on the basis of system integration. It is mainly on the basis of beam bridge analysis and construction process summary, according to the characteristics of road and bridge design of electronic computer PLC signal analysis and hydraulic system, the input of external supervision equipment displacement data, output hydraulic system residual oil control data signal, the use of a variety of hydraulic equipment to achieve balance. For the purpose of safe and efficient road and bridge jacking, the deviation of the jacking and landing accuracy does not exceed ±0.0.5 mm, the jacking load includes :50 tons -1000 tons, and the jacking height is 11mm to 500mm.
PLC more synchronous jacking hydraulic system is divided into electric hydraulic pump. PLC computer automatic control system. Hydraulic systems. Displacement pressure detection and industrial touch screen computer operating systems. The system is a hydraulic press jacking system. Calculate.
3. Synchronous jacking system software jacking whole process:
1. Install hydraulic jacks and displacement detection and sensing equipment. The hydraulic jacks must be installed to ensure that the road surface is smooth, and the displacement sensor must be installed to ensure that the suspension cable is vertical.
2. According to the distribution of hydraulic jacks, install hydraulic hoses, connect each hydraulic jack in series, and then use hydraulic hose hydraulic press to lift the oil inlet and outlet of the sewage treatment plant.
3. Connect the switching power cable. Connect the main power cable to the sewage treatment plant. Then connect the displacement detection device and the displacement detection terminal on the hydraulic jacking sewage treatment plant to the control cable according to the reference point.
4. Before the same lifting, first check whether the reading of the displacement sensor is accurate. The field staff will pull out the displacement sensor rope, and whether the reading on the display is the same as the displacement value pulled out by the field rope.
5. After the fitting button is implemented before synchronous jacking, the hydraulic jack gradually rises. When the specific working pressure reaches the value of the fitting working pressure, the hydraulic jack automatically terminates the jacking. The default value of the fitting working pressure is: the best default value is about 50% of the specific load.
6. After fitting, first set the target displacement and press and hold the rise button. At this time, the hydraulic jack will automatically rise, and when it rises to the overall target displacement of the lock, it will automatically terminate.
7. After fitting, first set the target displacement and press and hold the Reduce button. At this time, the hydraulic jack will automatically reduce, and when the overall target displacement of the lock is reduced, the automatic termination.
8. Single action operation: Turn the single action power switch to the left part and then raise it. Lower the button. Hold down the Stop or Total Stop button if you need to stop.

Application field
- Construction engineering: for the overall translation and jacking transformation of large buildings, such as the protection and relocation of historical buildings, the correction of high-rise buildings, etc.
- Bridge engineering: plays an important role in the installation process of Bridges, such as the simultaneous erection of prefabricated beams, as well as the overall jacking of Bridges during maintenance and reinforcement.
- Installation of industrial equipment: Installation and commissioning of large industrial equipment, such as generator sets, chemical equipment, heavy machine tools, etc., using synchronous lifting products can ensure the accurate placement of equipment.
1. Construction engineering
- Building overall jacking: For some buildings requiring overall displacement or renovation of the ground floor space, synchronous lifting technology can lift the entire building. For example, in the protection and migration of ancient buildings, by setting synchronous lifting jacks under the building foundation, the building can be smoothly lifted and moved to a new location or developed underground space at the original site without damaging the original structure of the building.
- Building correction: When the building tilts due to uneven settlement of the foundation and other reasons, synchronous lifting can be used to correct the building. The lifting equipment is placed on the side of the building where the settlement is less, and the building is gradually righted by precisely controlling the lifting force and displacement.
2. Bridge engineering
- Erection of prefabricated bridge beams: During the erection of prefabricated beams, synchronous lifting equipment is used to lift the prefabricated beams from the transport vehicles and accurately place them on the supports of the piers. Since prefabricated beams are usually heavier, synchronous lifting can ensure that multiple lifting points apply force at the same time, so that the beam body is in place smoothly and accurately, and avoid damage due to uneven force.
- Complete bridge jacking maintenance or renovation: For some Bridges that need to replace bridge supports, repair the substructure or undergo widening, the synchronous lifting system can be used to complete the bridge jacking. For example, the bridge support is replaced without interrupting the traffic, the bridge upper structure is lifted to a certain height by synchronous lifting jacks, and the bridge is lowered smoothly after the replacement of the support, minimizing the impact on traffic.
