Description
Technical field
The present invention relates to the pile leg locking mechanism in a kind of self-elevating ocean platform jacking system.
Background technology
Along with the develop rapidly of seafari and offshore wind farm, traditional bottom-supported platform has not satisfied the requirement of depth of water increase, working range expansion, and jack-up unit just grows up.It mainly is comprised of a barge shape hull (platform) and several Liftable type spud legs, and liftable spud leg can rise to hull the sea certain altitude, and can support the operation at sea of whole platform.Both can the lifting hull, also can the lifting spud leg, purpose is for operation at sea, falling ship and rising stake is in order to move boat.Lifting ship and lifting pole action are finished, and mainly finish by the lifting gear on the hull.From functional requirement and the expansion demand thereof of ocean platform, how the structure of its jacking system is carried out design and optimization, realize that lightweight will be an important research topic.
Summary of the invention:
The object of the invention is to the deficiency for the prior art existence, the pile leg locking mechanism in a kind of self-elevating ocean platform jacking system is provided.This mechanism design is ingenious, and is simple in structure, can be the lifting of ocean platform system service better.
In order to achieve the above object, design of the present invention is:
Adopt a kind of translation cam mechanism, cam center is positioned on the cam bolster, and the cam bolster retrains cam, only allows it that low-angle swinging arranged; Then worm-and-wheel gear driving crank slide block mechanism moves, slider-crank mechanism is to exist in pairs, lay respectively at the left and right sides of translation cam, wherein, slide block is replaced by spherical roller, it and translation cam routing motion, driving translation cam swings to the left or to the right, because the special profile of cam, thereby will lock the baffle plate compression or unclamp, finish self-locking and release.In the motion of cam, need the use location sensor that its position is detected.
According to above-mentioned design concept, this novel mechanism adopts following technical proposals:
Pile leg locking mechanism in a kind of self-elevating ocean platform jacking system, comprise the spud leg with stationary rack, two worm-and-wheel gears, two linkages, a cam mechanism and two latch mechanisms, it is characterized in that: the input of described two worm-and-wheel gears connects power source, and output connects cam mechanism through two linkages respectively; Described cam mechanism is positioned at the tooth top outside of spud leg stationary rack, and two latch mechanisms are installed in respectively the both sides of spud leg stationary rack; Two locking baffle plates are arranged in described two latch mechanisms under two hydraulic cylinder effects, make two locking baffle plate snap close/release spud leg stationary racks; Under the driving of power source, through the transmission of two worm and gears and two linkages, make the cam in the cam mechanism make to swing and compress/discharge described two locking baffle plates, thus the locking of realization spud leg/release.
Described worm-and-wheel gear comprises worm gear and worm engaging, has drive splines to connect power source in the rotating shaft of worm gear, and an end of a short connecting rod in the rotating shaft of worm screw and the linkage is fixedly connected with.
Described linkage comprises that long connecting rod and short connecting rod are hinged by connecting pin, and assurance can be rotated mutually; The other end of two long connecting rods is threaded connection with two claws of cam mechanism respectively.
Described cam mechanism comprises a cam, two claws and two ball rollers; Circular shape is made in described cam bottom, is convenient to locking, and cam is equipped with two position sensors, is used for detecting cam and whether turns to the precalculated position; Described ball roller is processed with groove, and the ball roller embeds cam by groove, finishes reliable connection, and two ball rollers are rotatably installed in respectively on two claws by pin.
Described two latch mechanisms comprise two hydraulic cylinders, two locking baffle plates and two cam bracing frames, the sensor sensing point are arranged, with described two position sensor cooperatings on the cam bracing frame; Described cam bracing frame is threaded connection and is fixed on the locking baffle plate; Described hydraulic cylinder is connected with the locking baffle plate by connecting pin, relatively rotates with assurance; Have in the described locking baffle plate double wedge can with spud leg stationary rack phase snap close; The end face of described cam bracing frame can compress mutually with described cam bottom arc surface.
Operating principle:
Pile leg locking mechanism in this self-elevating ocean platform jacking system is when locking work, receiving that behind lock signal, hydraulic cylinder stretches out, promoting the locking baffle plate and draw close towards vertical spud leg, until be adjacent to the tooth bar base, the motion of hydraulic cylinder is followed: fast close-be adjacent at a slow speed-leave fast; Then, under the driving of motor, the worm and gear system that is positioned at tooth bar base the right promotes the ball roller and moves downward along the translation cam profile, correspondingly the worm and gear on vertical spud leg left side system drives the ball roller with same motion mode and moves upward along cam contour, the worm and gear of two sides is that common participation just can prevent in carrying out self-locking and releasing process owing to the cam discontinuity causes deviation angle larger about only having, thereby affects whole transmission.Sensor sensing point on position sensor on being positioned at cam and the corresponding cam bracing frame is staggered motor output shaft and worm and gear power shaft by the commutation offset assembly on same plumb line the time, and self-locking is finished.
When release is worked, after receiving unlocking signal, be connected with the worm and gear power shaft by the output shaft of commutation offset assembly with motor, the moving ball roller of worm and gear frenulum that is positioned at tooth bar base the right moves upward along the translation cam profile, simultaneously, the moving ball roller of worm and gear frenulum that is positioned at the vertical spud leg left side moves downward along the translation cam profile.Sensor sensing point on nadir on being positioned at cam and the corresponding cam bracing frame staggers motor output shaft and worm and gear power shaft the motor stop motion by the commutation offset assembly on same plumb line the time.Drag the locking baffle plate by hydraulic cylinder subsequently and leave vertical spud leg, the complete release of system.
The present invention compared with prior art, have following remarkable advantage: the present invention designs ingenious, and is simple in structure, lightweight, replaces slide block mechanism in the past, solved the stressed excessive problem of slider support plate, solved simultaneously fully unsettled problem of actuated element.
