When vehicle device is locked, the first magnetic switch 98 is activated (the second magnetic switch 102 is in unactivated state at this time), to power plant
DCS (dcs) issues jiggering locking signal, while in jiggering control system, and the logic non-signal of the signal is made
For the necessary condition of jiggering engagement, i.e. jiggering barring gear in latched position can not engage.When barring gear is unlocked (figure
7), the second magnetic switch 102 is activated, and issues jiggering unlocking signal to DCS, jiggering control system allows barring gear to nibble at this time
It closes.9th retaining ring 96 is mounted in shift fork axle 83, to 84 stop of limit plate.
Jiggering control system, such as PLC controller, jiggering control system are connected to automatic locking mechanism and jiggering engagement
Mechanism, certainly, the jiggering control system can also connect frequency converter, Power Plant DCS, steam turbine MEH, and frequency converter is mounted on jiggering control
In cabinet processed, frequency converter is connected to motor and starting, frequency control for motor are used, and jiggering electrical control cabinet receives power plant
DCS and steam turbine MEH signal, control system are handled signal is received, and issue jiggering action signal, and by barring gear
State feeds back to Power Plant DCS.
Full-automatic jiggering realizes process: when turbine rotor needs jiggering, jiggering control system receives full-automatic jiggering
Instruction, locking pin cylinder solenoid valve obtains electric at this time, and gas source enters cylinder, cylinder piston band through the air inlet A103 of locking pin cylinder
Dynamic locking pin block fast retractile completes the unlock of barring gear to the position Fig. 7.The second magnetic switch 102 is activated simultaneously, to
DCS issues jiggering unlocking signal, and control system receives the logic non-signal of the first magnetic switch 98, and meshing condition meets, nibbles
Close cylinder solenoid valve obtain it is electric, compressed air through the second speed governing valve 69 enter cylinder, by the second speed governing valve 69 adjust intake velocity,
Cylinder piston rod is slowly shunk, and shift fork swivel plate is driven to rotate clockwise, since shift fork axle and shift fork swivel plate pass through spline chain
It connects, therefore shift fork axle also rotates clockwise, interior shift fork part rotates clockwise under the drive of shift fork axle at this time, to nibble with barring
It closes gear assembly and engages (idle gear of jiggering meshing gear component is engaged with turbine rotor gear) with turbine rotor gear.
When engagement in place when, shift fork swivel plate is just pressed on mechanical position limitation nut, prevents crossing for gear from engaging, while the on cylinder
Two position switch 74 (second position switch 74 is magnetic switch in Fig. 4) and limit switch 72 issue engage in place signal to jiggering
Control system.Jiggering control system receives engagement and waits after signal in place 5 seconds, and then jiggering control system issues to start and refer to
It enables, barring gear brings into operation.When turbine rotor is folded, when reaching rated speed, steam turbine prepares red switch, at this time steamer
Machine pitch is opened, and steam turbine MEH issues GO signal and gives jiggering control system, and jiggering disengages condition and meets, and compressed air is through first
Speed governing valve 67 enters cylinder (engagement cylinder 68), adjusts intake velocity by the first speed governing valve 67, piston rod quickly stretches out, and drives
Shift fork swivel plate rotates counterclockwise, and under the drive of shift fork axle, interior shift fork part drives meshing gear component Quick release.It disengages to
Behind position, (first position switch is magnetic switch to the first position switch 73 on cylinder in Fig. 4, and first position switch 73 judges disk
Whether vehicle disengages in place, second position switch 74 judge jiggering engagement in place) issue jiggering disengaged signal to jiggering control be
System.The locking pin cylinder solenoid valve power loss of barring gear, gas source enter cylinder, gas through the air inlet B104 of locking pin cylinder at this time
The cylinder piston drives locking pin block quickly to reach the position Fig. 6, completes the locking of barring gear.
Adjust automatically in engagement process: if jiggering gear and turbine rotor gear are encountered in engagement process is touched tooth, disk
Vehicle control by reset engage cylinder solenoid valve, i.e., engagement cylinder solenoid valve power loss, compressed air through the first speed governing valve 67 into
Enter and engage cylinder, jiggering disengages, and when jiggering disengages in place, engages magnetic switch (i.e. first position switch 73) quilt on cylinder
Activation issues to jiggering control system and disengages signal in place, and jiggering control system receives disengagement in place after signal to jiggering electricity
Machine issues pulse command, rotates motor, and the angle with barring meshing gear rotation half tooth, then control system swashs again
Engagement cylinder solenoid valve living carries out second of engagement and attempts.If second of engagement process still occurs touching tooth phenomenon, jiggering control
System will carry out repeating to appeal adjustment movement, then attempts third time and engages.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific implementation of the utility model
Example, and in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit of the utility model
And range.
