Utility model content
The purpose of this utility model is to provide a kind of BOP suspension arrangement for self-elevating ocean platform, solves that dynamic loading in prior art is relatively big, work efficiency is not high and installs the problem of centering correction inconvenience during BOP group.
This utility model be employed technical scheme comprise that, a kind of BOP suspension arrangement for self-elevating ocean platform, including pallet, pallet entirety is C-shaped shape, pallet upper surface is fixedly installed an adpting flange along line of symmetry, is positioned at adpting flange both sides and is provided with a pair ear mount；
A pair arc-shaped guide rail and a pair wearing plate it is symmetrically arranged with in the upper surface of pallet both sides prong, the wearing plate of every side is positioned at the inner side of this side arc-shaped guide rail, the wearing plate of every side and the arc-shaped guide rail of this side are provided with a spill slide block jointly, each spill slide block is provided with Baltimore groove；Each spill slide block is connected with a push action cylinder piston rod of this side, each push action cylinder cylinder body and this side, pallet upper surface lug corresponding connect.
BOP suspension arrangement for self-elevating ocean platform of the present utility model, is further characterized in that:
The cross section of arc-shaped guide rail is inverted "L" shaped, wearing plate be shaped as arc.
The corner of each spill slide block lower surface is respectively arranged with a roller set one, coordinates with arc-shaped guide rail two side elevation；It is respectively arranged with two roller set two in the outside of each spill slide block lower surface, coordinates with the inverted L-shaped wing plate lower surface of arc-shaped guide rail.
The beneficial effects of the utility model are, it is be rigidly connected between this self-elevating ocean platform BOP suspension arrangement and BOP group, this connected mode can limit two rotational freedoms of BOP group, it is ensured that during operation, Lifting Dynamic Load lotus is little, movement steady, effectively improves work efficiency；And can in the process installing BOP group, it is achieved the spinning movement to BOP group, flexible operation, it is simple to BOP group flange is connected with the centering of riser pipe bolt hole.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, structure of the present utility model is, including pallet 1, pallet 1 is by the box structure of steel plate installed-welded, viewing from above pallet 1 entirety and be C-shaped shape, reserve enough spaces to hold BOP group 8 in " C " type mouth, the lifting as BOP group 8 connects main body；Pallet 1 upper surface is fixedly installed an adpting flange 7 along line of symmetry, is positioned at adpting flange 7 both sides and is provided with a pair ear mount 6, for connecting the hoisting mechanism of BOP group 8；
A pair arc-shaped guide rail 4 and a pair wearing plate 5 it is symmetrically arranged with in the upper surface of pallet 1 both sides prong, the wearing plate 5 of every side is positioned at the inner side of this side arc-shaped guide rail 4, the wearing plate 5 of every side and the arc-shaped guide rail 4 of this side are provided with a spill slide block 2 jointly, each spill slide block 2 is provided with Baltimore groove, as contact surface socket corresponding to the projection on BOP group 8 lifting device；Each spill slide block 2 is connected with push action cylinder 3 piston rod of this side, each push action cylinder 3 cylinder body and this side, pallet 1 upper surface lug corresponding connect；
Spill slide block 2, push action cylinder 3, arc-shaped guide rail 4, wearing plate 5 are all be arranged symmetrically with (arranging respectively) along pallet 1 upper surface line of symmetry in prong upper surface, both sides, spill slide block 2 is the movable hold assembly of this part, holds up BOP group 8 by the mouth combined effect of " C " type.
The cross section of arc-shaped guide rail 4 is inverted "L" shaped, and rail shapes is arc.
Wearing plate 5 be shaped as arc, the wearing plate 5 of both sides is arranged symmetrically with, and symmetrical centre and pallet hold space center and overlap.
With reference to Fig. 4, Fig. 5, the corner of each spill slide block 2 lower surface is respectively arranged with a roller set 1 (the four rolling group 1 in Fig. 4), coordinates with 4 liang of side elevations of arc-shaped guide rail and realizes arcuately guide rail 4 horizontally-guided；Two roller set 2 10 (two roller set 2 10 in Fig. 5) it are respectively arranged with in the outside of each spill slide block 2 lower surface, coordinate with the inverted L-shaped wing plate lower surface of arc-shaped guide rail 4, play the effect preventing spill slide block from tumbling, it is achieved vertically support movement；
Under the coordination clamp standoff effect of roller set 1 and roller set 2 10, it is possible to ensure that the slip of spill slide block 2 is all the time without departing from arc-shaped guide rail 4.
Operation principle of the present utility model is,
1) with reference to Fig. 1, Fig. 4, Baltimore groove on spill slide block 2 is connected with the projection on BOP group 8 lifting device as contact surface, relying on the Baltimore groove on both sides spill slide block 2 as clamping contact position, combined effect, on BOP group 8 lifting device, completes the clamping to BOP group；Compared to the connected mode of existing suspension hook Yu otic placode, limiting more degree of freedom, make BOP group 8 not easily swing when lifting, movement, stationarity is better.
2) with reference to Fig. 2, under the effect of push action cylinder 3, spill slide block 2 slides (wearing plate 5 maintains static) along arc-shaped guide rail 4 relative wear plate 5, push action cylinder 3 piston rod making both sides during operation carries out stretching the action of a contracting, then two spill slide blocks 2 one enter to move back, making BOP group carry out pivotal action, pivotal angular range is determined by the stroke of two push action cylinders 3, but to ensure that spill slide block 2 can not depart from arc-shaped guide rail 4 two ends；Both sides arc-shaped guide rail 4, wearing plate 5 the center superposition holding space of the centre of gyration and pallet 1, it is ensured that the revolution of BOP group carries out around its center, it is simple to the centering of flange bolt hole.
3) with reference to Fig. 5, arc-shaped guide rail 4 cross section is " L " shape, the two sides of upper flange are the contact surface of the roller set 1 of spill slide block 2 both sides, bottom surface is the contact surface of roller set 2 10, roller set one is mainly used in side guide, and works with roller set 21 and can prevent spill slide block 2 from toppling because of unbalance stress.
