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.
The upper clamp of the lifting jack is connected with the piston of the jack, the lower clamp is connected with the support foot of the lower part of the cylinder, and each hydraulic jack has 2 grippers. Each gripper includes a gripper cylinder, a gripper device plate, and a gripper screw to enable the device to open and close the gripper during on-load descent. Through the hydraulic pump station, pressure oil is supplied to the lifting jack, and the jack piston is pushed to extend and contract the cylinder. When the cylinder is extended, the upper gripper set at the top of the piston tightenes the bearing steel strand so that the lifting weight moves upward with it. The lower gripper connected to the cylinder tightenes the bearing steel strand to ensure that the lifting weight stays in the new position safely and reliably. The upper gripper set together at the top of the piston relaxes the load strand and the piston returns to prepare for the next stroke. When raised in place, the jack piston tightens the bearing steel strand with the upper gripper at the position of almost complete cylinder extension, the lower gripper relaxes the bearing steel strand, and the piston cylinder reduces the weight. In the position close to the completely reduced cylinder, the lower clamp clamp the bearing steel strand, the upper clamp relax the bearing steel strand, the piston no-load extension cylinder, in the almost completely extended cylinder, the upper clamp clamp again the bearing steel strand, the lower clamp relax the bearing steel strand, so the cycle until the lifting weight is accurately in the design position. The hydraulic circuit of the hydraulic jack and pump station is equipped with a hydraulic control check valve and a balance valve, which can lock the oil circuit in the event of sudden power failure and other emergencies, so that the lifting weight can be safely suspended at a fixed height.
1. Check whether the Hydraulic Strand jack is normal before use.
2. Hydraulic Strand jack should strictly comply with the provisions of the main parameters, avoid ultra-high overload, otherwise when the lifting height or lifting tonnage
When the limit is exceeded, serious oil leakage will occur at the top of the cylinder.
3. such as manual pump body oil amount is insufficient, need to add to the pump should be fully filtered N33# hydraulic oil to work
Do.
4. Please refer to the manual for Synchronous lifting electric pump.
5. The center of gravity to choose moderate, reasonable choice of jack point of impact, the bottom surface to pad flat, while taking into account the ground
Soft and hard conditions, whether to liner tough wood, placing is smooth, so as not to load down or tilt.
6. After lifting the heavy object, the heavy object should be supported firmly with the support in time, and the jack is prohibited as a support
Use. If you need to support heavy objects for a long time, choose CLL self-locking jack
7. If you need several jacks lifting at the same time, in addition to the correct placement of the jack, should use multiple shunt valve, and each
The load of the jack should be balanced, and attention should be paid to keeping the lifting speed synchronized. The possibility of subsidence due to uneven weight must also be considered
The situation is to prevent the danger of tilting the object being lifted.
