Make, can be with no-harass switch when error, failure and maintaining.It is to reduce production to shut down using the purpose of fault-tolerant automated system
Time, it is error, failure or putting maintenance into practice no matter to shut down reason.The cost of downtime is higher, is more necessary using appearance
Wrong system.By avoiding production loss, the universal higher cost of investment of tolerant system can be quickly withdrawn.
As shown in Fig. 2 the sub- control device 82 of long-range windlass cabin, the sub- control device 83 of long-range windlass cabin and long-range windlass
The structure of the sub- control device 84 of cabin is identical with the structure of the sub- control device 81 of long-range windlass cabin.4 long-range windlass cabin
Control device (81-84) be according to the distribution situation of ship anchor arrange, the central controller (CPU) of driving cabin Surveillance center 2 and
Telecommunication is carried out using optical cable between long-range cabin control device 8 and between 4 sub- control devices of long-range cabin.In addition,
Each long-range cabin control device is again a distributed I/O.Each long-range cabin control device is designed with 3 identical tension windlass
Machine side operational control cabinet, is placed in the vicinity of identical tension windlass, to facilitate control cable to be connected with identical tension windlass.Identical tension anchor
Control panel is additionally provided with the operational control cabinet of machine machine side, in case every identical tension windlass is individually debugged and is used.When whole ship input is transported
During row, the control information of driving cabin is sent to cabin commutation system by optical cable first, then, then passes to every identical tension windlass
Machine side operational control cabinet, this transmission is two-way, the status information of identical tension windlass in turn, then is passed via contrary order
To driving cabin Surveillance center 2.
What is mainly put in identical tension windlass machine side operational control cabinet (87-89) in the present embodiment is distributed input/defeated
Go out (I/O) module.These distributed input/output (I/O) modules are relay control, frequency control control to anchor winch motor
The final realization of the operations such as system, brake electrical control, steel wire rope tension measurement, the measurement of withdrawing rope and parameter modification.Each is permanent
Tension force windlass machine side operational control cabinet correspondence one identical tension windlass of control.
The folding and unfolding strategy of windlass wirerope, formulates, i.e., mainly according to the motion of hull:Using vessel position information as
Feedback, so as to control the steady movement of ship.
As shown in figure 3, every identical tension windlass is equipped with braking machine, braking mechanism is provided with:One frequency conversion motor 13, variable-frequency electric
It is connected with an encoder 12 behind machine 13, to the rotating speed of measurement motor, a normal work is housed on the output shaft of frequency conversion motor 13
Be used as power brake 14, and in thereafter coaxial a shaft coupling 15 is filled, and is connected with speed change and brake output group 17 by shaft coupling 15,
Identical tension antivibrator 16 is housed on one end of the gear shaft of speed change and the end of brake output group 17, the other end passes through another coaxial tooth
Wheel is engaged with hoist gears group, to drive winch drum 11 to rotate.Wherein, frequency conversion motor 13 is selected:Power of motor is:
1080kW;Nominal torque is:10365Nm, rated speed is:995rpm, maximum speed are:2100rpm, highest use rotating speed
For:1800rpm, model:The frequency conversion motor of 1LA4500-6CV;The model that normal work power brake 14 is selected:YP41-
4500-900 × 30,23000Nm;The model that identical tension antivibrator 16 is selected:During WCB3365.5Bar, moment of torsion is 99kNm;Become
Speed and brake output group 17 are from the model selected:(brake)-disconnected (release) SBD365-C-1400X40 braking moments M=
150kNm。
Operation principle:Hull is walked:Because the power of shallow water pipe laying barge comes from identical tension windlass, so, identical tension anchor
During machine anchor take-up, tense wire rope, to drag hull walking, after during this period frequency conversion motor 13 is powered, braking mechanism is stopped
Car piece unclamps with brake wheel, and frequency conversion motor 13 drives gear reduction box, reel normal work by shaft coupling 15.It is pre- according to hull
The moving track calculation first set goes out the rope closing length of each anchor winch, and when drawing steel wire rope identical tension closed loop control is kept, drawstring
Speed can be selected by frequency conversion motor 13 and reduction box speed, meanwhile, other the identical tension windlass on ship all around symmetrically work,
Also steel wire rope is pulled with same tension force, makes hull at the uniform velocity smoothly advance.When bringing to:Windlass on ship all around symmetrical work
Make, with same power tense wire rope, to keep the steady of hull.When steel wire tension arrival setting value is detected, electric power liquid
Press disc type high speed braking operation (brake at a high speed), the brake block of braking mechanism under spring action with Eton brake wheel brake holding system
It is dynamic, prevent lift heavy from gliding, braking moment can adjust as needed initial tension of spring to determine.Machine oil oil pump feed profit is provided with reduction box
It is sliding, frequency conversion motor 13 is also required to during constant tensile control and is slightly rotated forward.Now, high speed braking operation, hydraulic disc brake and Eton
Brake works simultaneously.Additionally, mair motor is by Frequency Converter Control, rotating rotating speed can step-less adjustment, the outer band brake electricity of converter
Resistance.When windlass reversion drives mair motor that dynamic braking brake modes can be produced when inverting, control identical tension windlass reliably brakes, auxiliary
Help and realize constant tensile control.
Cast anchor:It is the process of loose cable when casting anchor for single windlass, motor is disengaged and driven, using damping brake control
Anchor hawser tension force, both can guarantee that the rope speed that of wirerope, and the lost motion of converter and motor is avoided that again.
At the same time, it is the steady of holding hull, it is necessary to still protected by the windlass of other symmetric positions for being distributed in hull
Hold constant tensile control.
During constant tensile control, by the range of tension force, and fluctuating margin can be set, concrete numerical value can be in debugging
Further arrange.
Above-mentioned industrial control computer, man-machine interface, main control station, ethernet communication equipment, OLM near-end opto-electronic conversion
Device, OLM distal ends optical-electrical converter, communication module, distributed input/output (I/O) module, cabin fairing are existing skill
