Below with reference to concrete example and corresponding accompanying drawing to the walking displacement of walking assembling self-elevating drilling platform, turn to displacement, vertical lift, offshore boring island by jacking to sea (lake) face and creep into the operating principle that platform fixes and be explained in detail.
" river " type walking assembling self-elevating drilling platform comprises main platform 1 and two assistance platforms 2.Two assistance platforms 2 are arranged at the both sides of main platform 1, as Fig. 5.
As Fig. 3, Fig. 4, Fig. 5, Fig. 6, when " river " type walking assembling self-elevating drilling platform walking displacement, based on two assistance platforms 2, start lifting fluid cylinder 203, main platform 1 is lifted away from 1 ~ 1.5 meter on ground, and then the displacement fluid cylinder 202 that is connected in the horizontal direction of startup and moving body 201, displacement fluid cylinder 202 is rolled by the displacement car body 201 following rollers that flexible and drive are connected with lifting fluid cylinder 203, and by spandrel girder 5 main platform 1 is moved forward 10 meters.After main platform 1 moves successfully, start the lifting fluid cylinder 203 that is connected in vertical direction with moving body 201, main platform 1 is vertically transferred, just main platform 1 is fallen earthward; And then be basic point with main platform 1, starting lifting fluid cylinder 203 rises two assistance platforms 2, two assistance platforms 2 can be lifted from ground, startup makes it flexible with the displacement fluid cylinder 202 that moving body 201 is connected in the horizontal direction then, just driving two assistance platforms 2 moves forward, when with main platform 1 snap after fall earthward, repeatable operation according to this just can be with " " type walking assembling self-elevating drilling platform integral body step by step is moving forward to the desired position in the river.
Respectively be provided with at the two ends of spandrel girder 5 by turning to fluid cylinder 52 controls to do the Rocker arm 51 of divertical motion, to realize as Fig. 7 when offshore boring island turning to when the depth of water is 1 ~ 2 meter waters.
When offshore boring island turns to, based on main platform 1; the lifting fluid cylinder 203 on the Rocker arm 51 comes 2 liters of jack-up of two assistance platforms; handle the corresponding fluid cylinder 52 that turns to then; corresponding Rocker arm 51 is rotated; drive two assistance platform 2 little rotating certain angle (being approximately about 1 degree), after this rotating operation success, transfer lifting fluid cylinder 203 two assistance platforms 2 are landed.Again based on two assistance platforms 2, start lifting fluid cylinder 203 with main platform 1 jack-up, repeatable operation according to this can make that " " type walking assembling self-elevating drilling platform finally turns on the required direction in the river.
When " river is " when type walking assembling self-elevating drilling platform marches to predetermined sea (lake) district, as Fig. 2, start the secondary or the multi-stage expansion fluid cylinder 21 that are arranged at pile 23 tops, push four pile posts 23 to sea (lake) end, the stake footwear for the treatment of pile 23 bottoms touch sea (lake) during the end, pile 23 overcomes the weight of offshore boring island under the effect of secondary or multi-stage expansion fluid cylinder 21, impel pile 23 firm being fixed on the bed of sea (lake).This moment is under the effect of secondary or multi-stage expansion fluid cylinder 21, again with offshore boring island progressively jacking to 3 meters in distance sea (lake) face, by the fastening devices on the caisson unit 3 that pile 23 clampings are firm then, make pile 23 being fixed on the bed of sea (lake) steadily so that assistance platform 2 is more stable.
Because two assistance platforms 2 and main platform 1 be relative to be platform independently separately, safe and reliable when guaranteeing that further offshore boring island is worked.As Fig. 5, between main platform 1 and assistance platform 2, be symmetrically arranged with 3 pairs of locking devices 8.The fixed cover 80 of locking device 8 is arranged on the main platform 1, and the extending cylinder 82 of locking device 8 and the telescopic 81 that is connected with the plunger of extending cylinder 82 are arranged on the assistance platform 2, and fixed cover 80 and telescopic 81 are all used welded steel plate rectangularity frame construction.When offshore boring island is raised to predetermined height by sea (lake) face, start extending cylinder 82, telescopic 81 can be penetrated in the fixed cover 80 of main platform 1, therefore, just can firmly main platform 1 and assistance platform 2 be fixed as one; In addition, the fixed cover 80 of locking device 8 also can be arranged on the assistance platform 2, and the extending cylinder 82 of locking device 8 and the telescopic 81 that is connected with the plunger of extending cylinder 82 are arranged on the main platform 1, when offshore boring island is raised to predetermined height by sea (lake) face, start extending cylinder 82, telescopic 81 can be penetrated in the fixed cover 80 of assistance platform 2, main platform 1 and assistance platform 2 can be fixed as one equally.
As Fig. 8, " returning " type walking assembling self-elevating drilling platform, main platform 1 is arranged at assistance platform 2 in " returning " frame of " returning " type structure.The working method of " returning " type walking assembling self-elevating drilling platform walking displacement is identical with " river " type walking assembling self-elevating drilling platform.Be about to main platform 1 10 meters of frame internal shifts, land then, assistance platform 2 is risen displacement, 10 meters of steps moves to the desired position with offshore boring island according to this.The lifting that turns to displacement, offshore boring island, offshore boring island of " returning " type walking assembling self-elevating drilling platform by jacking to sea (lake) face and creep into working method that platform fixes and all to assemble self-elevating drilling platform identical with " river " type walking.
As Fig. 9, " mountain " type walking assembling self-elevating drilling platform, assistance platform 2 is arranged at three sides of main platform 1.The walking displacement of " mountain " type walking assembling self-elevating drilling platform, the lifting that turns to displacement, offshore boring island, offshore boring island by jacking to sea (lake) face and creep into the working method that platform fixes and assemble the identical of self-elevating drilling platform with the walking of " returning " type, but this kind arrangement mode of main platform 1 and assistance platform 2 has been avoided the useless area of " returning " type walking assembling self-elevating drilling platform empty, can better realize the application that can be used as the workspace area of offshore boring island.
