Detailed description of the invention
Illustrate embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing; but the present embodiment is not limited to this utility model; every employing analog structure of the present utility model and similar change thereof; all should list protection domain of the present utility model in, the pause mark in this utility model all represents the relation of sum.
As shown in Figure 1-Figure 3, a kind of battle pin formula lifting of ocean platform device that this utility model embodiment is provided, including spud leg 1, and at least one hoist cylinder 4, the most each ring beam 3 that can slide up and down it is equipped with along spud leg on described spud leg 1, one of them ring beam 3 is affixed with the cylinder body of each hoist cylinder 4, and another ring beam 3 is affixed with the piston rod of each hoist cylinder 4；
It is characterized in that: the outer wall of described spud leg 1 is fixed with many vertical rail bars 2, each rail bar 2 is laid around the central axis symmetry of spud leg；
Equipped with rotating annular battle pin 5 on described ring beam 3, battle pin 5 is concentric with ring beam 3 lays (i.e. the ring mandrel line of battle pin and the ring heart dead in line of ring beam), equipped with the battle pin oil cylinder 6 for driving battle pin 5 to rotate on ring beam 3, multiple pin block 51 it is fixed with on the medial wall of battle pin 5, and the quantity of pin block 51 is consistent with the quantity of the rail bar 2 on spud leg, and each pin block 51 is around the central axis symmetry laying of spud leg；
All offer multiple cotter ways 21 that the pin block 51 being available on battle pin comes in and goes out on every rail bar 2, and each cotter way 21 on rail bar is the most equidistantly laid.
In this utility model embodiment, described battle pin 5 is removably formed by connecting by multiple circular arc plates.
In this utility model embodiment, equipped with two proximity switches on described ring beam 3, one of them proximity switch is for solving lock-switch, another proximity switch is locking switch, described battle pin 5 is provided with the trigger unit for triggering two proximity switches, the installation position of the trigger unit on battle pin matches with the installation position of on ring beam two proximity switches, when the pin block making battle pin turn on battle pin inserts the cotter way on spud leg, trigger unit on battle pin can trigger the locking switch Guan Bi on ring beam, and when battle pin turns to the cotter way on the pin block removal spud leg on battle pin, trigger unit on battle pin can trigger the solution lock-switch Guan Bi on ring beam.
When this utility model embodiment uses, by one of them ring beam 3(lower ring) affixed with ocean platform 7, each proximity switch on each ring beam is respectively connected to the electric control system of each battle pin oil cylinder so that electric control system can control each battle pin oil cylinder according to the signal of each proximity switch and run.
The operation principle of this utility model embodiment is as follows:
When ring beam is in released state, the piston rod of the battle pin oil cylinder on ring beam is retracted, and the pin block on battle pin also removes the cotter way on spud leg, and the trigger unit on battle pin triggers the solution lock-switch Guan Bi on ring beam；
Need ring beam when released state is changed to lock-out state, the piston rod making battle pin oil cylinder stretches out, thus drive battle pin to rotate clockwise, when battle pin turns to the cotter way that the pin block on battle pin inserts on spud leg, trigger unit on battle pin triggers the locking switch Guan Bi on ring beam, locking switch on ring beam sends a locking signal immediately to electric control system, and electric control system controls the battle pin oil cylinder stopping action on ring beam therewith, and now ring beam locks with spud leg；
Need ring beam when lock-out state is changed to released state, the piston rod making battle pin oil cylinder is retracted, thus drive battle pin to rotate counterclockwise, when turning to the cotter way on the pin block removal spud leg on battle pin when battle pin, trigger unit on battle pin triggers the solution lock-switch Guan Bi on ring beam, solution lock-switch on ring beam sends a unlocking signal immediately to electric control system, and electric control system controls the battle pin oil cylinder stopping action on ring beam therewith, and now ring beam unlocks with spud leg；
During original state, two ring beams are in lock-out state, and each hoist cylinder is all in the state of stretching out；
When needing to control ocean platform rising, first lower ring is unlocked with spud leg, each hoist cylinder is made to make the retraction stroke of a pitch again, it is allowed to drive ocean platform to rise a pitch, the most again lower ring is locked with spud leg, upper ring beam is unlocked with spud leg, make each hoist cylinder one pitch of work the most again stretches out stroke, upper ring beam is locked with spud leg, the most repeatedly, until ocean platform rises to the height set；
When needing to control ocean platform decline, first upper ring beam is unlocked with spud leg, each hoist cylinder is made to make the retraction stroke of a pitch again, being locked with spud leg by upper ring beam, unlocked with spud leg by lower ring, make each hoist cylinder one pitch of work the most again stretches out stroke, it is allowed to drive ocean platform to decline a pitch, the most again lower ring is locked with spud leg, the most repeatedly, until ocean platform drops to the height set.
