As shown in figure 17, driving device 83 comprises transmission shaft 17, motor coupler protective cover 22, plate disc brake 23 and motor coupler, intermediate shaft coupling protective cover 24, intermediate shaft coupling 25, variable-frequency motor 26, water-cooled brake 27 and the support etc. of speed-change gear box 20, gear case.Speed-change gear box 20 is the parallel shafts box typed structure, three grades of transmissions of four axles, and wherein, input shaft is connected with variable-frequency motor 26 by plate disc brake 23 and motor coupler, and tween drive shaft is connected with water-cooled brake 27 and support by intermediate shaft coupling 25.
Motor adopts conversion system to drive, and has the advantages such as infinite speed variation, speed-regulating range width, adjusting speed accuracy height and speed regulation process be steady.Compare than hydraulic-driven, can avoid oil leaking pollution, problem such as configuration Large-scale Hydraulic Pumping Station etc., the characteristics such as it is little to have a volume, and the unit efficiency is high, and cost is relatively low.Most platform anchoring system all adopts the frequency conversion drive mode.Through type selecting, motor is selected French EMERSON product, and variable-frequency motor 26 adopts 6-pole motor, and the three phasevoltage of 690V, reference frequency are 50Hz, and power is 585kW, and nominal torque is 5701Nm, and torque peak is 12150Nm, is 2.13 times of nominal torque.At first, variable-frequency motor 26 will cooperate in harmony with speed-change gear box 20 one, can guarantee that a whole set of windlass normally moves, operation and drive characteristic according to windlass under the different operating modes and speed-change gear box 20, the mechanical specialities of adjustable frequency motor 26 and the output characteristic of large-capacity transducer are studied in great detail, realize the optimum matching of frequency-conversion drive apparatus and speed-change gear box and windlass.Secondly, anchor mooring positioning system comprises the operating condition of Various Complex, and every kind of operating mode is not quite similar to the requirement of motor, in the stage of casting anchor, cast anchor finish after, whether success needs to confirm cast anchor; In the anchoring stage, the impact of ocean engineering platform wind-engaging, wave, stream, tide can be moved, and at this moment, need to adjust continually according to the situation of movement of platform the tension force of corresponding anchor chain; In the stage of weighing anchor, according to the situation that anchor chain reclaims, anchor chain tension force and speed are accurately controlled and adjusted.The 3rd, motor in the anchor mooring positioning system need to adapt to very abominable running environment, except waving, the factor such as shock and vibration, humidity, salt fog and mould, will accomplishing especially that also wave has a direct impact device, make it can adapt to for a long time the rugged environment condition.At last, a series of problems such as because the service conditions of motor is more abominable, the traditional electrical chance brings that Efficiency Decreasing, heating are serious, vibration and noise increase, thus cause the reliability of motor and service life greatly to be reduced; In addition, when satisfying power, range of speed and voltage class, also must consider the type of cooling, degree of protection, range of speed, dielectric level, resonance problem and the shaft current problem of motor, so that therefore the long-time running that motor can be safe and reliable selects variable-frequency motor comprehensively.
The miniature gears 6 of the left and right windlass body apparatus in both sides adopts the gear wheel shaft form, is connected with gearbox shaft and transmission shaft 17 by power-transfer clutch 5 realizations, and power-transfer clutch 5 adopts rectangular spline to be connected with miniature gears 6 and transmission shaft 17.Middle windlass body apparatus is provided with denture clutch 15, and transmission shaft 17 passes denture clutch 15 transmitting torques.Because every cover windlass is by a gear case transferring power, distance is larger between the windlass, therefore the open pinion 6 of left and right windlass body apparatus and the right alignment between the transmission shaft 17 require very high, otherwise power-transfer clutch 5 can't be to upper, even can affect gear transmission, cause simultaneously very large additional bending moment etc., affect the performance of transmission shaft rigidity and gear case.This structure is convenient to the integral installation of windlass, and the right alignment between miniature gears 6 and the transmission shaft 17 requires also to adjust easily to be guaranteed.
For the ease of installing and making, transmission shaft 17 is designed to segmentation structure, and middle continuous with spline coupling, 17 transmitting torques of transmission shaft do not bear moment of flexure.Short gearbox drive axle 17 passes gear case, and matches with the right windlass body apparatus of gear case gear; The long right windlass body apparatus of transmission shaft 17 and speed-change gear box 20 the right and middle windlass machine body apparatus matches.Three windlass are realized the break-make of power and miniature gears by power-transfer clutch, and the power-transfer clutch closure is all thrown off for other two when a windlass job wherein.Power-transfer clutch is that this installs fluid control by clutch control device control, and under the effect of hydraulic power control, clutch oil cylinder promotes or the pulling shift fork, power-transfer clutch is in throws off or closure state, and the power-transfer clutch status has corresponding travel switch to detect.
Speed-change gear box 20 is adopted as the parallel shafts box typed structure as the most key parts of driving device, three grades of transmissions of four axles, divide low gear, high speed gear and neutral, the high speed gear transmitting ratio is 27.9, and the low gear transmitting ratio is 77.4, adopts low gear when duty ratio is larger; When load is low weight, adopt high speed gear; When casting anchor the water-cooled braking action, adopt neutral.The nominal torque of gear case is 400kNm, and the overload moment of torsion is 620kNm.The high/low speed shelves are located on the low speed tween drive shaft, and neutral gear is located on the high speed tween drive shaft, and the high/low speed shelves separate with neutral, are conducive to guarantee that the gear case shift process is reliable, accurate, slide piece can not occur, stop a grade phenomenon.The gear case selector fork also is that the position also has corresponding travel switch to detect, and is the same with clutch control device, all provides power by hydraulic efficiency pressure system by 28 controls of gear case variable block speed governing oil cylinder.Gearbox output shaft is to come transmitting torque in the mode of hollow slow-speed shaft locking dish, replacing common key connects, this designs simplification processing technology, made things convenient for Assembly ﹠Disassembly, and the rigidity of connection of axle and bending resistance, the anti-twisting property of mechanical axis have been improved, reduced the distortion of output shaft end, simultaneously just because the split of output shaft and drop-gear box so that driving device and both sides windlass body apparatus be equipped with certain variable range.
Platform location windlass generally disposes the water-cooled brake as the cloth anchor/drg that casts anchor, and the dynamic load that produces when providing enough braking potential control to cast anchor guarantees to emit continuously anchor chain, and restriction anchor chain speed avoids the anchor chain excessive velocities to have an accident.The water-cooled brake by the cooling system cooling, reaches the requirement of braking and lasting heat radiation to the mechanical energy conversion heat.Relatively rotate the generation resistance during brake work between inner rotator and the housing, the kinetic energy that anchor chain is moved is converted into rapidly heat energy, and cooling water expansion tank will recept the caloric, and heat is taken away.This type Brake Energy is controlled at the decline load in a certain speed range, hinders its speed and accelerates but can not fully load be checked; Control lock torque by the cooling water flow that flows into the water-cooled brake, when not having cooling water expansion tank to pass into, just do not produce lock torque; When cooling water expansion tank passes into and strengthens gradually, produce lock torque and also strengthen gradually, until greatest limit.
