Fig. 2 is overlooking the structure diagram of the present utility model.
In figure, 1. blowout preventer crane, 2. compressed air hoist, 3. from mobile handcart, 4. electric crane, 5. hanging beam guide rail, 6. rail
Road, 7. pulley, 8. steel wire rope, 9. suspension hook, 10. control chamber, 11. I-steel guide rails.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in detail.
With reference to Fig. 1, Fig. 2, structure of the present utility model is to be provided with cantilever beam including in drilling platforms afterbody, this cantilever
It is, below beam, the pithead position that preventer is located, in cantilever beam, longitudinal (left and right directions of Fig. 1) is provided with two I-steel and leads
Rail 11, this two I-steel guide rails 11 hangs and is simultaneously installed with two blowout preventer cranes 1；
In cantilever beam, well head center corner relatively is respectively arranged with a compressed air hoist 2, and four compressed air hoists 2 are equal altogether
Control with control chamber 10 and be connected；Every compressed air hoist 2 each draws steel cable 8, and steel wire rope 8 passes through pulley 7 with suspension hook 9 even
Connect, four suspension hooks 9 assist blowout preventer crane 1 jointly to sling preventer together；
In addition, track 6 is vertically arranged with drilling platforms deck, track 6 is provided with from mobile handcart 3, track 6
External end head stretch out drilling platforms deck afterbody, the inner termination position of track 6 is provided with pressure testing seat；The cantilever of in rail 6 top
The lower surface fixation of beam deck is hung with two hanging beam guide rails 5, and this two hanging beam guide rails 5 are be arranged in parallel with track 6, this two hanging beams
Electric crane 4 is provided with guide rail 5.
Blowout preventer crane 1 adopts pneumatic control structure, from 37.5 tons of crane of load-carrying, is arranged on two I-steel guide rails
On 11, airlift reaches 75 tons, be aim at preventer install, the dismounting of in place, well head and the mobile device that designs.Handling preventer
When, the crane of this 37.5 tons of two load-carrying works simultaneously and lifts equipment, operates steadily, easy to operate, by preventer in well head and
Handling back and forth between pressure testing seat.
Because preventer weight is larger, and well head center is unfavorable for that personnel closely operate, and holds during handling
Easily generation swing is abnormally dangerous, and the load-carrying of therefore four compressed air hoists 2 is 5 tons, diagonal setting, using long-distance centralized control,
By steel wire rope 8, gib head 9 hook is fixed on preventer, in moving process, keeps the steady of preventer, assist preventer
Well head is in place and centering.
It is 8.5 tons from the maximum load of mobile handcart 3, preventer groundwork place is at well head center, if it happens former
Barrier will integrally hang out, then using from mobile handcart 3, by preventer, the large-tonnage from well head center movement to main deck hangs
Machine overlay area, is transferred from platform by deck loop wheel machine.910 millimeters of the rail spacing of the guide rail 6 being located from mobile handcart 3, highly 480 millis
Rice, 27 meters of the length of guide rail 6, stretch out 2 meters of main deck afterbody.
Electric crane 4 lifting maximum load is 10 tons, carries out the movement of preventer from mobile handcart 3 for auxiliary, and
The maintenance of most of time preventer is placed on carrying out on main deck, and such working place is larger.So electric crane 4 is in maintenance
During play very important effect, handling and the dismounting of each parts can be completed, simultaneously can also handling other thing
Product.7310 millimeters of the rail spacing of the hanging beam guide rail 5 that electric crane 4 is located, 27 meters of total length, stretch out 2 meters of cantilever beam deck front end.
1, four compressed air hoists 2 of two above-mentioned blowout preventer cranes, it is provided with each from mobile handcart 3, electric crane 4
Power-driven mechanism, respectively control or coordinate control, during movement, staff only needs to carry out hook operation and dismantles
Hook operates.
Device of the present utility model, main innovation point is：1) due to being limited by explosion-proof area, arrange preventer in well head
Crane 1, had not only met use requirement but also had improved safety；2) the explosion-proof restriction in cantilever beam region is relatively low, using electric crane 4, volume
Little, lightweight, lifting is fast with movement speed, improves work efficiency；3) package is closed using cantilever beam platform structure
Removing the work is put, be preventer provide completely, easily movement and maintenance channel；4) hang without using the other ships beyond platform
Installing standby being serviced, what electric crane 4 and the setting from mobile handcart 3 not only solved that preventer keeps in repair above deck hangs
Shipment transmission function, provides miscellaneous equipment maintenance, installation, handling, and goods and materials in crane overlay area on main deck to deposit simultaneously
Lifting, can be cost-effective；5) take into full account the movement safety of preventer, by central controlled four compressed air hoists 2
Auxiliary, minimizing personnel in the operation of overhead positions and reduce operator's quantity, improve work efficiency.
