Abstract
The invention provides a multi-point synchronous hydraulic jacking system. The multi-point synchronous hydraulic jacking system comprises a plurality of jacks, wherein a displacement sensor is arranged on each jack and used for detecting displacement of the jack; a solenoid valve is connected with the oil inlet end of each jack; the output terminals of the displacement sensors are all connected with slave control boxes; the output terminals of the slave control boxes are electrically connected with the solenoid valves; the oil inlet ends of the solenoid valves are connected with an oil pump through a main oil pipe; and a speed limit valve is arranged on the main oil pipe between the oil pump and the solenoid valves. Multiple points can be controlled by the slave control boxes to work synchronously, and part of the points can be operated to work synchronously; and some independent point can also be independently regulated, so that the practicability is high.
Description
Technical field
The invention belongs to hydraulic lifting technical field, be specifically related to a kind of Multi-point synchronization hydraulic lifting system.
Background technology
At present at engineering fields such as the slipform process of building operation and the large tank reverse installation processes of installation work, all need to use jacking apparatus.And common jacking apparatus generally adopts hydraulic pressure or air pressure as power.Pneumatic jacking device owing to needing by gas compression in an airtight large diameter tubular material such as steel pile casting, steel pipe pile, so the danger easily leaking air and set off an explosion.For this kind of large-sized object of the large diameter tubular such as steel pile casting, steel pipe pile material, once the accident of blasting, consequence is by hardly imaginable.Although hydraulic jacking device is not easy to occur explosion accident, utilize hydraulic pressure as power, its shortcoming is exactly that the speed of jacking is excessively slow, can extend the time of whole construction, increases the input cost of engineering.And jacking is carried out to multiple accounting for for needing in building construction process simultaneously simultaneously, but do not have suitable jacking apparatus the large diameter tubular stable material quality such as large tank, steel pile casting, steel pipe pile, fast speed can be reclaimed at present.
Summary of the invention
The object of the present invention is to provide a kind of Multi-point synchronization hydraulic lifting system, realize synchronously accurately controlling to carry out jacking operation to multiple construction point.
For achieving the above object, present invention employs following technical scheme:
A kind of Multi-point synchronization hydraulic lifting system, comprise multiple jack, described each jack is respectively provided with one for detecting the displacement pickup of its displacement, the oil inlet end of each jack is respectively connected with an electromagnetic valve, the mouth of institute's displacement sensors is all connected with a point control box, and the mouth of described point of control box is electrically connected with each electromagnetic valve respectively; The oil inlet end of described electromagnetic valve is connected with oil pump by oil main line; Oil main line between described oil pump and electromagnetic valve is provided with governor valve.
Further scheme, described oil pump, speed limit case are electrically connected with overhead control case respectively, and described overhead control case is serially connected with at least two points of control boxs by 485 buses, and each point of control box is at least electrically connected with 6 electromagnetic valves and 6 displacement pickups.
Further scheme, described overhead control case and computing machine carry out interactive mode and are connected.
During this practical sample is novel, a point of control box at least can control 6 jacks, the maximum quantity of control box is divided to be 16, divide after carrying out series winding by 485 buses between control box and be connected with overhead control case, then can realize carrying out jacking operation to 16 × 6=96 some position simultaneously.The work of 96 some bit synchronizations can be controlled by each point of control box, can also operate for wherein a part of some position, realize certain part point and be synchronized with the movement; Can also adjust separately some some positions separately.Adjusted the jacking stroke of jack by the adjustment of governor valve, carry out operation in conjunction with governor valve and a point control box and can realize the different stroke of each point position jacking; Also can the difference jacking such as between consecutive points in certain sequence (automatically calculate and generate arithmetic progression); A jacking can complete whole setting stroke, also can be divided into a lot of small steps, each small step jacking completes the jacking automatically entering next small step, and all multiple small steps have added up the jacking process of whole stroke; Whether the state of kinematic motion of each point position, in the residing stage, exceed restriction allowed band simultaneously, and whether motion is normal, and system shows and Real-Time Monitoring all in real time.
If the device failure of certain any position, do not have enough time to change device, this some position adopts orthodox method command displacement, does not affect the operation of other some positions of whole system.
