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
