Below the top of the wedge bracket 9 of lift-type platform, two lower end of lower lift cylinder 5 is connected to below the deck of jack-up unit
On deck 10, the distance between upper ring beam 2 and lower ring 4 can be increased as far as possible in this way, the row of ring beam 2 and lower ring 4 in guarantee
Journey prevents the too short elongation for leading to lift cylinder of the distance between ring beam 2 and lower ring 4 from cannot reach range.
Specifically, it is respectively equipped with connection otic placode below the top of wedge bracket 9 and above upper ring beam, upper lift cylinder 3
Both ends pass through connection otic placode and pin shaft respectively and connect with wedge bracket 9 and upper ring beam 2, under the top and lower ring 4 on two decks 10
Side is also respectively equipped with connection otic placode, and the both ends of lower lift cylinder 5 pass through connection otic placode and pin shaft and two decks 10 and lower ring respectively
Beam 4 is connected.
In the present embodiment, the distance between two pin hole 1a adjacent in same row pin hole 1a be a, (according to
The distance between two neighboring pin hole 1a a determines the stroke of oil cylinder, i.e., lift cylinder is from shortest contraction state to longest
Elongation state stroke slightly larger than a), when upper lift cylinder 3 and lower lift cylinder 5 are retracted to shortest route, upper ring
The distance between beam 2 and lower ring 4 are greater than 3a.It is such to be arranged so as to lift cylinder 3 and the elongation arrival of lower lift cylinder 5
When range, do not collide between upper ring beam 2 and lower ring 4.
In the present embodiment, the first plugging pin oil cylinder 6 is identical with the quantity of upper lift cylinder 3, and the second plugging pin oil cylinder 7 is mentioned under
The quantity of oil-lifting jar 5 is identical, and each upper lift cylinder 3 is provided respectively therein the surface of first plugging pin oil cylinder 6, often
A lower lift cylinder 5 is provided respectively therein the underface of second plugging pin oil cylinder 7.Such structure is conducive to structural loads
Direct transmitting, the whole uniform force on ring beam.
Preferably, in the present embodiment, upper ring beam 2 and lower ring 4 are ring structure.The welding node of ring structure compared with
Few, the intensity and reliability of structure are higher.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
