Below with reference to concrete example and corresponding accompanying drawing to the walking displacement of walking assembled jack-up drilling platform, turn to displacement, vertical lift, drilling platform by jacking to sea (lake) face and creep into the principle of work that platform fixes and be explained in detail.
" river " type walking assembled jack-up 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, such as Fig. 5.
Such as Fig. 3, Fig. 4, Fig. 5, Fig. 6, when the walking of " river " type walking assembled jack-up drilling platform is shifted, take two assistance platforms 2 as the basis, 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, roller below the displacement car body 201 that displacement fluid cylinder 202 is stretched and drive is connected with lifting fluid cylinder 203 rolls, and by bearing beam 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 take main platform 1 as basic point, starting lifting fluid cylinder 203 rises two assistance platforms 2, two assistance platforms 2 can be lifted from ground, then startup makes it flexible with the displacement fluid cylinder 202 that moving body 201 is connected in the horizontal direction, just driving two assistance platforms 2 moves forward, when with main platform 1 snap after fall earthward, according to this repeatedly operation just can " " type walking assembled jack-up drilling platform integral body step by step move to arrive forward the desired position in the river.
Respectively be provided with at the two ends of bearing beam 5 by turning to fluid cylinder 52 control to do the Rocker arm 51 of divertical motion such as Fig. 7, take realize when drilling platform the depth of water turning to during as 1 ~ 2 meter waters.
When drilling platform turns to, take main platform 1 as the basis; the lifting fluid cylinder 203 on the Rocker arm 51 comes 2 liters of jack-up of two assistance platforms; then handle the corresponding fluid cylinder 52 that turns to; corresponding Rocker arm 51 is rotated; drive two angles (being approximately about 1 degree) that assistance platform 2 little rotations are certain, after this rotating operation success, transfer lifting fluid cylinder 203 two assistance platforms 2 are landed.Take two assistance platforms 2 as the basis, start lifting fluid cylinder 203 with main platform 1 jack-up again, according to this repeatedly operation can make that " " the type walking assembled jack-up drilling platform finally turns on the required direction in the river.
When " river is " when the type walking assembled jack-up drilling platform marches to predetermined sea (lake) district, such 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 drilling platform under the effect of secondary or multi-stage expansion fluid cylinder 21, impel pile 23 firmly to be fixed on the bed of sea (lake).This moment is under the effect of secondary or multi-stage expansion fluid cylinder 21, again with drilling platform progressively jacking to 3 meters in distance sea (lake) face, then by the anchor fitting on the caisson unit 3 that pile 23 clampings are firm, make pile 23 being fixed on the bed of sea (lake) so that assistance platform 2 is more stable steadily.
Because two assistance platforms 2 and main platform 1 be relative to be platform independently separately, safe and reliable when guaranteeing that further drilling platform is worked.Such as Fig. 5, between main platform 1 and assistance platform 2, be symmetrically arranged with 3 pairs of latching devices 8.The fixed cover 80 of latching device 8 is arranged on the main platform 1, and the extending cylinder 82 of latching 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 framed structure.When drilling platform 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 latching device 8 also can be arranged on the assistance platform 2, and the extending cylinder 82 of latching device 8 and the telescopic 81 that is connected with the plunger of extending cylinder 82 are arranged on the main platform 1, when drilling platform 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.
Such as Fig. 8, " returning " type walking assembled jack-up drilling platform, main platform 1 are arranged at take assistance platform 2 in " returning " frame of " returning " type structure.The mode of operation of " returning " type walking assembled jack-up drilling platform walking displacement is identical with " river " type walking assembled jack-up drilling platform.Be about to main platform 1 10 meters of frame internal shifts, then land, assistance platform 2 is risen displacement, 10 meters of steps moves to the desired position with drilling platform according to this.The lifting that turns to displacement, drilling platform, drilling platform of " returning " the type walking assembled jack-up drilling platform by jacking to sea (lake) face and creep into the fixing mode of operation of platform with all identical with " river " type walking assembled jack-up drilling platform.
Such as Fig. 9, " mountain " type walking assembled jack-up drilling platform, assistance platform 2 are arranged at three sides of main platform 1.The walking of " mountain " type walking assembled jack-up drilling platform displacement, the lifting that turns to displacement, drilling platform, drilling platform by jacking to extra large (lake) face and creep into the identical of mode of operation that platform fixes and " returning " type walking assembled jack-up drilling platform, but this kind arrangement mode of main platform 1 and assistance platform 2 has been avoided the useless area of " returning " type walking assembled jack-up drilling platform empty, can better realize the application that can be used as the work area area of drilling platform.
