Abstract
The invention relates to a mooring and positioning device for an offshore drilling platform, which comprises a central controller, at least one mooring and positioning winch and a separating control device, wherein the central controller collectively controls working conditions of each mooring and positioning winch, the separating control device is respectively connected with the central controller and the each mooring and positioning winch, and the mooring and positioning winch is a water-cooled mooring winch with variable frequency resistance. Because a plurality of mooring and positioning winches are used for positioning, and a computer performs central control treatment, a cable of each mooring and positioning winch is in constant tension condition; because the mooring and positioning winch is designed into a multi-braking structural style, the diameter of a brake wheel is reduced, and space occupied by the winch on the platform is reduced; because a water cooled brake is provided, components are cooled in time, and service life of the components is prolonged; and because a wound roll is designed into a structure with a step rope guiding groove, stress condition of the cable is changed during winding, and abrasion of a wire cable is reduced.
Description
Technical field
The present invention relates to the equipment that positions on the offshore oil drilling drilling platform, specifically a kind of mooring locating device for sea drill platform.
Background technology
Through the relevant patent documentation of retrieval; Do not retrieve at present the mooring locating device for sea drill platform identical as yet with structure of the present invention; The existing mooring positioning device that applies to carry out on the ocean drilling platform of oil exploration generally take by many mooring winches separately the mode of control come drilling platform is positioned stable, though the location of drilling platform is played a significantly greater role because the marine operation stormy waves is big; This is difficult to obtain equilibrium for hawser stressed of separate unit mooring winch; Thereby make the stable of marine drilling platform cause very big danger, thus be necessary prior art is improved, to adapt to the needs of ocean operation better.
Summary of the invention
The objective of the invention is to provide a kind of employing computing machine centralized control many mooring winches, make the cable stress of each controlling point mooring winch controlled, can carry out a kind of mooring locating device for sea drill platform of self-balanced according to the stressing conditions of hawser.
In order to realize the object of the invention; Considering that each point stress balance automatic guidance and mooring winch can effectively carry out on the heat-dissipation basis; Mooring locating device for sea drill platform of the present invention is designed to comprise central controller, at least one mooring positioning winch, distributed control device, described each mooring positioning winch of central controller centralized control working condition; Described distributed control device is connected with central controller, each mooring positioning winch respectively; Described mooring positioning winch is made up of frame, drum part, sensor, transmission gear parts, arrangement of clutch, drive motor, high-speed brake, retarder, rope winding jib, low speed brake equipment, water-cooled brake, and described drum part is arranged on the frame; Axle head at drum part is provided with sensor, and sensor links to each other with distributed control device; Described transmission gear parts are arranged on the drum part; And be meshed with gear on the water-cooled brake, described arrangement of clutch is connected with water-cooled brake, retarder respectively, and retarder is arranged on the frame; Retarder is connected with drive motor; Between drive motor and retarder, be provided with high-speed brake, described drive motor is arranged on the frame, on drum part, is provided with the low speed brake equipment; Described rope winding jib is arranged on the frame, and is used to control the sway of the hawser of drum part.Described mooring positioning winch is for having frequency conversion resistor water cooled mooring winch.
Reel in the drum part of described mooring positioning winch is the structure with ladder conductor rope groove.
The arrangement of clutch of described mooring positioning winch is a hydraulic clutch apparatus.
The drive motor of described mooring positioning winch is a variable frequency drive motors.
The water-cooled brake of described mooring positioning winch is the mechanism of Friction disk dynamic brake, and the formation cooling structure that is connected with seawater.
During use, many mooring positioning winch are individually fixed in around the drilling platform, and are connected with distributed control device, and distributed control device is connected with central controller again, and the hawser of each mooring positioning winch navigates to marine desired location respectively under the traction of the ship that casts anchor.Discharge in the process of hawser; The release rate of rope roll detects through sensor; And data-signal is sent to distributed control device, and distributed control device is sent to central controller with information again, and central controller is handled detected signal; Make the instruction of control rope roll release rate, and the work of control high-speed brake and water-cooled brake, low brake.For the tension force that makes each hawser keeps balance, water-cooled brake is designed to the version of dynamic brake.In braking procedure, will produce a large amount of heats, in order to reduce temperature, water-cooled brake is connected with seawater and cools off.Have good positioning back or when meeting sea beat, sensor feeds back to central controller with the pulling force that bears of its hawser respectively of each mooring positioning winch, central controller is realized the stress balance of each mooring positioning winch hawser through the work of control mooring winch.
Advantage of the present invention is: owing to adopt many mooring positioning winch to carry out each point location, and carry out centring control through computing machine and handle, thereby make the hawser of each mooring positioning winch be in permanent tension condition; Because the mooring positioning winch is designed to many brake structural type, thereby the brake wheel diameter is reduced, made things convenient for and made and transportation, reduced winch shared space on platform; Owing to be provided with water-cooled brake, thereby the glancing impact parts in time cooled off, reduced the wearing and tearing of parts, improved the service life of parts, reduced the device damage that parts bring because of marine corrosion simultaneously; Because spool designs becomes to have the structure of ladder conductor rope groove, thereby change the stressing conditions of hawser when twining, reduced the wearing and tearing of steel rope, improved service life; Owing to be provided with sensor, thereby the stressed and release rate of hawser in time detected, realized the purpose of automatic guidance mooring positioning winch; Because rational in infrastructure, degree of automation is high, dependable performance is so there is very big practical and popularizing value.
