The specific embodiment
Referring to Fig. 1, the hydraulic lift of offshore boring island mainly is to be made of the pile 2 on the platform 1 that is fixedly set in offshore boring island, elevating mechanism 3 and the seat stake mechanism 4 that is arranged on the caisson 5 of offshore boring island.
Elevating mechanism 3 is main by two lifting hydraulic cylinders 31 on the platform 1 that is fixedly installed on offshore boring island, constitute with three clamping hydraulic cylinders 32 of fixedlying connected of lifting hydraulic cylinder 31 and the slips 33 of fixedlying connected with the plunger of clamping hydraulic cylinder 32, and selecting lift herein for use is 3 ~ 4 meters lifting hydraulic cylinder 31.Three clamping hydraulic cylinders 32 are positioned on the same horizontal plane and the central axis with respect to pile 2 is symmetrical arranged along the side of pile 2; It is corresponding that slips 33 is stuck in the side of the face of pile 2 and pile 2, and be provided with the steel thorn that is used to increase engaging frictional force at the face that slips 33 is stuck in pile 2.
Seat stake mechanism 4 is mainly by being arranged at three seat stake hydraulic cylinders 41 on the caisson 5, being arranged at the outside of pile 2 and the seat stake taper sheath 42 of fixedlying connected with caisson 5 and a slips sheet 44 of fixedlying connected with a seat hydraulic cylinder 41 by leverage 43 constitute, and three seat stake hydraulic cylinders 41 are positioned on the same horizontal plane and the central axis with respect to pile 2 is symmetrical arranged along the side of pile 2.Slips sheet 44 is arranged at the top of caisson 5 and matches with seat stake taper sheath 42; It is corresponding that this slips sheet 44 is stuck in the side of the face of pile 2 and pile 2, and be provided with at the face that slips sheet 44 is stuck in pile 2 and increase the steel of engaging frictional force thorn.
Below in conjunction with Fig. 1 the concrete working method of the hydraulic lift of this offshore boring island is elaborated.When offshore boring island needs lifting, at first start clamping hydraulic cylinder 32, the slips 33 of fixedlying connected with the plunger of clamping hydraulic cylinder 32 will tightly be clamped pile 2.It is up to start seat stake hydraulic cylinder 41 this moment, to break away from seat stake taper sheath 42 with the slips sheet 44 that seat stake hydraulic cylinder 41 is fixedlyed connected by leverage 43, start lifting hydraulic cylinder 31 then, stretch out downwards, this moment, offshore boring island upwards rose, when lifting hydraulic cylinder 31 stretches out 3 ~ 4 meters, it is descending to start seat stake hydraulic cylinder 41, slips sheet 44 is embedded in the seat stake taper sheath 42 until chucking, because therefore the outer tapering that is with of slips sheet 44 can block pile 2 firmly.This moment clamping hydraulic cylinder 32 being resetted makes slips 33 break away from pile 2; And lifting hydraulic cylinder 31 resetted, according to this action repeat each 3 ~ 4 meters can with creep into platform safe lift away from the sea level.
Figure 2 shows that another embodiment of the present utility model.The elevating mechanism 3 of the hydraulic lift of this offshore boring island mainly by the pitching pile hydraulic cylinder 34 that is fixedly set on the platform 2 and is positioned at caisson 5 tops be symmetrically set in pile 2 both sides and constitute with the latch hydraulic cylinder II 36 of fixedlying connected of pitching pile hydraulic cylinder 34; The seat stake mechanism 4 of the hydraulic lift of offshore boring island is for being symmetricly set in the both sides of pile 2 and being positioned at latch hydraulic cylinder I 35 on the platform 1, and is provided with the pin hole 21 that matches with latch hydraulic cylinder I 35 and latch hydraulic cylinder II 36 respectively on pile 2.
Below in conjunction with Fig. 2 the concrete working method of present embodiment is elaborated as follows.When offshore boring island needs lifting, start latch hydraulic cylinder I 35, then the plunger of latch hydraulic cylinder I 35 withdraws from from pin hole 21, reset pitching pile hydraulic cylinder 34 this moment, promoting pile 2 descends 3 ~ 4 meters, after pile 2 declines put in place, start latch hydraulic cylinder I 35, then the plunger of latch hydraulic cylinder I 35 inserts in the pin hole 21.Start latch hydraulic cylinder II 36 then, its plunger withdraws from from pin hole 21, and after withdrawing from fully, the withdrawal of the plunger of pitching pile hydraulic cylinder 34 drives latch hydraulic cylinder II 36 and rises, and when reaching pin hole 21 positions of pile 2, stops to promote.So repeatedly, step by step pile 2 is inserted into specified altitude assignment, and offshore boring island is risen to corresponding height.At last, when arriving the precalculated position, the plunger of latch hydraulic cylinder I 35 and latch hydraulic cylinder II 36 is stretched out and insert in the pin hole 21 of pile 2, by the wedging device stake is fixed simultaneously.
