Working principle: selection uses the quantity of stride machine first on touch screen or industrial personal computer, selects linkage pattern, setting
Jack initial levelling height value, the initial levelling pressure value of setting jacking, lifting height value after setting jacking is levelling, setting jacking
De- beam pressure valve, sets pushing tow synchronous contrast value parameter.
The first step selects linkage work mode on station, and jacking is then clicked on touch screen or industrial personal computer
Petrol station electric motor starting button starts corresponding jacking petrol station motor according to the seat in the plane number of input.Operation jacking rises button, accordingly
Jacking cylinder rises, the following conditions:
1, according to the levelling height value of the setting of touch screen or industrial personal computer, corresponding group's stride machine jacking cylinder is risen to
It stops working behind levelling position.
2, jacking cylinder continues to rise after preceding (1) condition meets, and judges that levelling pressure set by touch screen or industrial personal computer is
No arrival setting value, reaches to jack after setting levelling pressure and stops working, and is being in close contact between stride machine and box beam at this time
State.
3, stride machine jacking cylinder continues to rise after preceding (2) condition meets, and jacking cylinder need to rise to touch screen or industry control
It stops working after machine synchronization settings height, box beam is detached from interim pier at this time.
4, preceding (3) condition judges whether box beam pressure valve reaches setting value after meeting, reach setting pressure and stop working, push up
Rising a working link at this time terminates.
Second step, the click pushing tow electric motor starting button on touch screen or industrial personal computer, pushing tow petrol station electric motor starting, according to
Pushing tow on touch screen or industrial personal computer sets correction value, according to the corrected parameter value of setting by displacement sensor to pushing tow
Oil cylinder is modified synchronous push, and box beam is moved along, and pushing tow displacement sensor judges that pushing tow reaches stroke, and pipe bending cylinder stops
Only；Pushing tow knot beam.
Third step, after pushing tow pushes away, the jacking of stride machine starts to drop, according to the setting stride on touch screen or industrial personal computer
Machine jacking drop parameter value, starting top lifting button, stride machine jacking drop stop working after reaching setting drop parameter value, this time step
The jacking of shoe machine is detached from box beam, and box beam is placed above interim pier.
4th step, after the jacking of stride machine is dropped, stride machine pushing tow is returned, and starting stride machine pushing tow returns button, and pushing tow is returned, arrived
It stops working after up to the origin of displacement sensor, stride machine returns to position and terminates at this time.
5th step, if being shifted according to actual field situation box beam carries out correction movement using left and right deviation correcting device.
