Description
Technical field
The utility model belongs to field of steel structure construction in the construction, especially the horizontal sliding of steel structure control field.
Background technique
Adopt oil hydraulic pump as power source in the existing steel structure sliding construction mostly, promote to be moved to assigned direction by sliding component through hydraulic jack.But in work progress,, make by sliding component easy problem that causes direction skew even disengaging sliding rail because of reasons such as unbalance stress in moving process owing to the monitoring that lacks displacement amount, hydraulic jack pressure and other parameters.
Summary of the invention
The purpose of the utility model is the level of synchronization slip control system of a kind of closed loop of design.In multiple spot synchronization-sliding process, but the displacement amount and the variation in pressure of this synchronization-sliding control system detection at any time each point slippage, and checkout value compared.When relatively difference is greater than the setting permitted value, regulate the propelling force and the fltting speed of each oil cylinder automatically, make by a plurality of promotion points of sliding component and in the displacement difference that allows, move all the time, thereby guarantee by the safety of Sliding Structures part.
The scheme that solves the utility model technical problem is: in the hydraulic jack that slippage is used, install and measure the displacement transducer of slippage, setting pressure sensor outside hydraulic jack is respectively applied for the displacement amount of measurement slippage and the size of each point thrust.Master controller is provided with the Profibus EBI, and the communication unit that in minute control box, is connected with sub-controller simultaneously also has the Profibus EBI, and master controller is connected through the Profibus bus with sub-controller; Between master controller and sub-controller, carry out data communication through the Profibus bus protocol.Adopt the communication of RS485 agreement between master controller and the man-machine interface, man-machine interface shows each point displacement amount and pressure in real time, and sub-controller is carried out the control signal that master controller sends.In minute control box, the signal acquisition process module is connected with displacement transducer, pressure transducer and proportional velocity regulating valve respectively, has the displacement signal of collection, pressure signal, the function of output control signal.
In use, behind operator's primer fluid press pump, the button through main control box sends the instruction of hydraulic jack extension and contraction control again, sets offset deviation and the pressure difference that allows through man-machine interface.During work; Master controller stretches out instruction with hydraulic jack and sends to the branch control box through the Profibus bus; After communication unit in the branch control box receives this instruction, send signal to solenoid directional control valve, the overhanging promotion steel structure of hydraulic jack is moved through sub-controller; The shift value of sensor and force value are sent in the signal acquisition process unit of branch control box, after treatment these signals are uploaded to master controller through communication unit and Profibus bus.Master controller calculates comparison to the displacement signal and the pressure signal of a plurality of points; In case when relatively difference allows difference greater than setting, send the adjustment instruction to a minute control box, divide control box to receive above-mentioned instruction through communication unit through the Profibus bus; Again control signal is transferred to the signal acquisition process unit; Through the aperture of resize ratio series flow control valve, regulate the motion speed of corresponding hydraulic jack, to reach the purpose of dwindling each point displacement difference and pressure difference.In whole slipping, measure at any time incessantly, calculate relatively also control in time so that a plurality of horizontal translocation point is being set the scope inter-sync work of displacement difference and pressure difference.
Compare with existing technology, the utlity model has following advantage:
1. in whole slipping, adopt closed loop control, the shift amount and the force value of dividing the signal acquisition process unit in the control box to gather each point are at any time uploaded master controller after treatment; Master controller is regulated displacement difference and pressure difference at any time through calculating relatively, so that whole slipping is being set operation continuously in the scope that allows in displacement difference and pressure difference.Owing to regulate at any time, each point jacking displacement difference is controlled in minimum (being far smaller than the displacement difference of the traditional sliding technology) scope.
2. the signal that is recorded by sensor is sent into master controller again after the signal acquisition process cell processing of minute control box.In signal processing unit, the signal of surveying handle through modes such as filtering, impedance conversion, analog-to-digital conversion, greatly improved the stability and the precision of signal, and the anti-interference in the transmission course.Protective measures such as overvoltage, excess current, the Security that has improved signal in the collecting treatment process, signal have been implemented simultaneously.
3. adopt the Profibus bus to carry out data communication between master controller and sub-controller, effectively reduce external interference, increased the distance of signal transmission, improved the reliability of communication the influence of data transmission and the quantity of signal transmssion line.
4. adopt hydraulic proportional speed regulating control technology; The system that can guarantee is under the condition of continuous operation; The aperture that changes series flow control valve through control signal is controlled the overhanging speed of hydraulic jack, has improved the speed and the precision of control, has guaranteed the continuity and the Security of construction.
