Work process and the principle thereof of the present invention are as follows:
TBM cutterhead combination drive includes two kinds of operating modes: nominal situation and operating mode of getting rid of poverty.
Under nominal situation, main driving frequency conversion motor 11.1 and the moment of torsion provided from driving frequency conversion motor 11.2 can meet the moment of torsion required for drive system 13, frequency conversion motor 1 is driven not work, variable displacement motor switch valve 9 dead electricity connects, the discharge capacity of variable displacement motor 10 is adjusted to minimum, variable displacement motor 10 dallies, rotate forward with variable displacement motor 10 that (B10 hydraulic fluid port goes out hydraulic oil, A10 hydraulic fluid port enters low pressure oil) as a example by, the control port pressure of the B side of flushing valve group 8 is higher than the control port pressure of A side, reversal valve bottom work in flushing valve group 8, the hydraulic oil that the B10 hydraulic fluid port of variable displacement motor 10 flows out flows into from the B9 hydraulic fluid port of variable displacement motor switch valve 9, flowed out by the A9 hydraulic fluid port of motor switch valve 9；The fluid part that oil-supplementing system 6 provides flows into fuel tank 5 by repairing overflow valve 4, remaining fluid flows out from the A3 oil-out of repairing check valve group 3, the fluid part flowed out from A3 oil-out enters from the A8 hydraulic fluid port of flushing valve group 8, fuel tank 5 is flowed back to by the T8 hydraulic fluid port of flushing valve group 8, remaining fluid converges with the hydraulic oil of the A9 hydraulic fluid port outflow of variable displacement motor switch valve 9, is co-flowed into the A10 hydraulic fluid port of variable displacement motor 10.
Get rid of poverty under operating mode, main driving frequency conversion motor 11.1 and the moment of torsion provided from driving frequency conversion motor 11.2 are unsatisfactory for the moment of torsion required for drive system 13, frequency conversion motor 1 is driven to start, motor switch valve 9 must electric not connect, as a example by driving frequency conversion motor 1 to rotate forward, the A2 hydraulic fluid port oil-feed of dosing pump 2, B2 hydraulic fluid port goes out hydraulic oil, the control port pressure of the B side of flushing valve group 8 is higher than the control port pressure of A side, reversal valve bottom work in flushing valve group 8, the fluid part that oil-supplementing system 6 provides flows into fuel tank 5 by repairing overflow valve 4, remaining fluid flows out from the A3 oil-out of repairing check valve group 3；The hydraulic oil flowed out by B2 hydraulic fluid port enters through the B10 hydraulic fluid port of variable displacement motor 10, A10 hydraulic fluid port flows out, the oil return part flowed out from A10 hydraulic fluid port enters from the A8 hydraulic fluid port of flushing valve group 8, fuel tank 5 is flowed back to by the T8 hydraulic fluid port of flushing valve group 8, remaining oil return converges with the fluid of the A3 oil-out of Fill valve group 3, is co-flowed into the A2 hydraulic fluid port of dosing pump 2；Torque signal is passed to the input of controller 14 by torque sensor 12, signal is after controller 14 calculating processes, being exported by controller 14 outfan, the signal after process passes to the control port of variable displacement motor 10, the discharge capacity of regulated variable motor 10 through motor displacement gain module 15；Signal after process passes to the more powerful control port driving frequency conversion motor 1 through torque gain module 16 simultaneously, as the reference torque driving frequency conversion motor 1.When cutterhead starts to get rid of poverty, set and drive the reference torque of frequency conversion motor 1 as mair motor moment of torsion * motor quantity/hydraulic system efficiency, setting motor displacement makes system pressure near Intermediate High Pressure, and makes the output moment of torsion of variable displacement motor 10 basically identical with Motor torque；When still not getting rid of poverty, increase, while increasing the discharge capacity of variable displacement motor 10, the reference torque driving frequency conversion motor 1, driving frequency conversion motor 1 is to reach reference torque to automatically achieve the rotating speed of needs, enough working flows and pressure is provided for variable displacement motor 10, by the synchronous coordination to the discharge capacity of variable displacement motor 10 and the reference torque driving frequency conversion motor 1, feasible system operating pressure basically identical.
