Description
Technical field
The utility model relates to a kind of ocean winch, particularly relates to a kind of electric drive active compensation ocean winch.
Background technology
Ocean winch mainly refers to rely on Scientific Research Ship, exploration of ocean resources ship, ocean engineering support boat, and the ocean engineering ships such as seabed pipeline construction ship are for promoting and transfer the winch of weight.Ocean winch operating environment is severe, and working load is unstable, and safe reliability requires high.Ocean winch must have adapt to lumpy heave compensation function, enough large cylinder sizes and rope woolding capacity, can with the cable sector of cylinder coordination and safe and reliable brake gear.
Ocean winch structure mainly contains two types, i.e. single drum integration winch and trailer coupling and the separation type winch extension and retraction system that Chu Lan mechanism separates separately, front and back are arranged.Single drum integration winch is applicable to being arranged on the deck of marine ship, have that load is little, system be simple, compact conformation, the feature such as transport and easy for installation, low cost of manufacture, well can complete input and recovery operation, but the weight of folding and unfolding weight acts directly on capstan drum and hawser, cause the friction between the tension force of capstan drum upper cable, hawser and extrude very large, wirerope wearing and tearing can be aggravated, the deficiencies such as reduction of service life.MacArtney company of current Denmark, Dynacon company of the U.S., Jiangsu Haitai Ship's Whole Set Co., Ltd., Shanghai Laolei Instrument System Co., Ltd. etc. are manufacture order reel integration ocean winch all.Separation type winch extension and retraction system is primarily of traction winch and storage winch two parts composition, and traction winch is arranged in after retractable frame, and cable sector and Chu Lan mechanism are arranged sequentially in after traction winch successively.Identical by structure, tactic two capstan winches of traction winch are formed, on each capstan winch with 6-8 parallel or inclination cable groove at a certain angle.During winch work, hawser enters traction winch by the end that bears a heavy burden, and (usually have 6-8 cable grooves) after being wound around multi-turn successively on two capstan winches of traction winch, two winch dishes synchronously drive, and are completed promoting or lowering function by the friction force between cable groove and hawser.Because hawser is more in the traction winch winding number of turns, hawser and the effect of rope groove friction power make the tension force of traction winch rear end (being connected with storage winch) greatly reduce relative to front end (load coupling end).And the tension force born due to storage winch cable is less, deep-sea winch multilayer row cable can also be greatly reduced to the destruction of umbilical cables.But the structure of this separation type winch is relatively complicated, and size is huger, comparatively greatly, applicable installation belowdecks or the ship deck space occasion of relatively having more than needed for transport and installation footprint.Odim company of current Norway and Dynacon company of the U.S. all produce this separation type winch extension and retraction system, and wherein Norway Odim company mainly produces electrical drawworks, and Dynacon company of the U.S. mainly produces hydraulically-powered winch.
Winch work circumstance complication in ocean is severe, limited working space, maintenance and installation inconvenience, and ocean winch lifting object is all generally the high precision instrument and equipment of price.In order to ensure the safe folding and unfolding of these expensive equipments, improve the safe reliability of ocean winch, usual employing multiple stage frequency converter, multiple electric motors drag capstan drum, the synchronized Coordinative Control problem that this just relates to multiple stage frequency converter, multiple electric motors drags same load and main transmission power redundancy allocation problem.Multi-motor synchronous control technology takes actv. measure of control, the synchronized Coordinative Control technology of research multiple stage frequency converter, multiple motors, realize the synchronous pulling of multiple electric motors, i.e. torque, power division are even, reach smooth pulse-less in whole speed adjustable range, low cruise is steady, improves dynamic property and the steady-state behaviour of multi-cell drive system, coordinate the normal operation between each motor, guarantee that ocean winch shear reliably runs.Main transmission power redundancy configuration on the one hand ocean winch drive motor is equipped with enough large power, ensures the normal folding and unfolding of ocean winch and heave compensation function; On the other hand the power of configuration will disperse, i.e. gross horsepower as requested, by multiple motors mean allocation.Motor redundant as Denmark MacArtney novel sea winch is equipped with 6, under the ocean working environment that complexity is severe, if wherein 1-3 platform motor breaks down, remaining motor normally works and still can ensure ocean winch shear reliability service, guarantees the safe retrieving of expensive equipment.
Heave compensation system can be divided into passive type heave compensation system and active heave compensation system, passive type heave compensation system realizes passive compensation with the form such as gas spring, hydraulic efficiency pressure system usually, substantially not consumed energy, but compensation precision is lower, and need larger energy storage volume.Active heave compensation system normally arranges the impact that actuator brings with Active Compensation heave movement, and its principal feature is that compensation precision is high, and antijamming capability is strong, but need consume comparatively multi-energy.The many Active Heave Compensation System described in the literature, are driven by hydraulic pressure or pressure system usually.Hydraulic pressure or air pressure active compensation principal feature are that Active Heave Compensation System adopts hydraulic pressure or pneumatic control system to drive winch.But, such ocean hoister system structure relative complex, and there is the risk of process fluid leakage in hydraulic pressure or air pressure.
The external research having carried out electric drive ocean winch, and have Related product to emerge, its cardinal principle is the load driven by motor on the basis of Conventional marine winch in heave movement.
