Description
Technical field
This utility model relates to ocean platform jack up lowering or hoisting gear, particularly to a kind of double-layer movable ring beam hydraulic bolt formula
The continuous lowering or hoisting gear of cylinder spud leg.
Background technology
Hydraulic bolt formula self-elevating ocean platform mainly has, determines ring beam structure at present.Relative to double-layer movable ring beam structure,
Move, determine the simple in construction of ring beam, it is simple to manufacture processing, but during lifting platform, have wait this process of oil cylinder backhaul, rise
Fall process is discontinuously lifting, and average rising or falling speed is relatively low, causes working platform inefficient.Platform is at pre-ballast and bears storm
During load, load is very big, now can only lean on and determine one layer of latch of ring beam and bear load, and the averagely load to a latch is relatively big,
Danger coefficient is higher.After platform is lifted to working depth, can only lean on and determine ring beam and fix, if sea bed injustice may result in hull
The longitudinal and transverse problem such as incline, the safety to platform affects.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, it is provided that a kind of simple in construction, safe and reliable, user
Just double-layer movable ring beam hydraulic bolt lowering or hoisting gear.
The purpose of this utility model is achieved through the following technical solutions: a kind of double-layer movable ring beam hydraulic bolt formula cylinder pile
The continuous lowering or hoisting gear of lower limb, including circle spud leg, described cylinder spud leg is cased with wedge bracket, on rotating ring beam and lower rotating ring beam, in institute
State rotating ring beam and be provided with rotating ring beam bolt mechanism and upper connection bearing pin, described lower rotating ring beam is provided with lower rotating ring beam latch
Upper rotating ring beam described in mechanism and lower rotating ring beam connecting pin be arranged over upper strata oil cylinder, described upper strata oil cylinder and described wedge bracket it
Between be provided with connection otic placode, described lower rotating ring beam be arranged over lower floor's oil cylinder, between described lower floor oil cylinder and described wedge bracket
It is provided with lower connection otic placode.
Further improvement of the utility model is: be arranged over upper strata hoist cylinder, individual upper strata at upper rotating ring beam
Hoist cylinder is distributed in the circumferencial direction of described wedge bracket.
Further improvement of the utility model is: be arranged over lower floor hoist cylinder, individual lower floor at lower rotating ring beam
Hoist cylinder is distributed in the circumferencial direction of described wedge bracket.
This utility model compared with prior art has the advantage that
Without waiting for the time of oil cylinder backhaul lifting when, rising or falling speed is greatly improved, and improves work efficiency；
Pre-ballast peace platform bears storm load when, the latch of two-layer rotating ring beam is had to undertake load together, significantly
Reduce the load suffered by single latch, improve the safety of platform, and reliability；
Compensate for the longitudinal and transverse problem of inclining of hull caused under platform pitching pile holding state due to sea bed injustice, available upper and lower
Rotating ring beam oil cylinder pressurize is adjusted supporting.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Label in figure: rotating ring beam, 5-upper rotating ring beam latch machine under 1-cylinder spud leg, 2-wedge bracket, 3-upper rotating ring beam, 4-
Rotating ring beam connecting pin, 9-upper strata oil cylinder, the upper connection of 10-under rotating ring beam bolt mechanism, 8-under structure, 6-upper rotating ring beam connecting pin, 7-
Otic placode is connected under otic placode, 11-lower floor oil cylinder, 12-.
Detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, this utility model is made further
Describing in detail, this embodiment is only used for explaining this utility model, is not intended that the restriction to this utility model protection domain.
As Fig. 1 shows the one of this utility model a kind of double-layer movable ring beam hydraulic bolt formula continuous lowering or hoisting gear of cylinder spud leg
Planting embodiment, including being cased with wedge bracket 2, upper rotating ring beam 3, lower rotating ring beam 4 on cylinder spud leg 1, described upper rotating ring beam 3 is provided with
Upper rotating ring beam bolt mechanism 5 and upper connection bearing pin 6, described lower rotating ring beam 4 is provided with lower rotating ring beam bolt mechanism 7 and lower rotating ring beam
That goes up rotating ring beam 3 described in connecting pin 8 is arranged over upper strata oil cylinder 9, is provided with between described upper strata oil cylinder 9 and described wedge bracket 2
Connect otic placode 10, described lower rotating ring beam 4 be arranged over lower floor's oil cylinder 11, between described lower floor oil cylinder 11 and described wedge bracket 2
It is provided with lower connection otic placode 12；
Upper rotating ring beam is hinged with hull wedge bracket by 4 oil cylinders, and lower rotating ring beam is hinged with wedge bracket by 4 oil cylinders,
4 set bolt devices it are respectively provided with on upper and lower rotating ring beam.
When liter platform, upper strata oil cylinder is in shortest route state, and upper latch inserts spud leg hole, and spud leg extracted by lower latch
Hole, upper strata oil cylinder stretches out lower floor's oil cylinder retraction platform simultaneously and is lifted, until upper strata oil cylinder reaches Chang lower floor after a pitch
Oil cylinder is reduced to the shortest, and lower latch inserts, and upper latch is extracted.Lower floor's hoist cylinder stretches out upper strata oil cylinder retraction platform simultaneously and is lifted
Rising, until upper strata oil cylinder is reduced to Duan lower floor oil cylinder and reaches the longest after a pitch, upper latch inserts, and lower latch is extracted, so
The most above-mentioned action reaches the purpose of liter platform.During fall platform, lower latch inserts in spud leg hole, and spud leg hole extracted by upper latch, under
Layer oil cylinder retraction upper strata oil cylinder simultaneously stretches out platform and does down maneuver, until after a pitch, lower floor's oil cylinder is retracted on the shortest
Layer oil cylinder reaches the longest, and upper latch inserts, and lower latch extracts, and oil cylinder lower floor's oil cylinder simultaneously of retracting in upper strata stretches out platform and does and decline
Action, until after a pitch, upper strata oil cylinder is reduced to Duan lower floor oil cylinder and reaches the longest, lower latch inserts, and upper latch is extracted,
The most above-mentioned action, completes the purpose that platform declines；Can be by upper and lower layer oil cylinder synchronization of jacking up, receipts when the pre-ballast of storm, pile pulling
Contract piling and pile pulling.
This utility model double-layer movable ring beam structure is without waiting for the time of oil cylinder backhaul lifting when, and rising or falling speed is big
Big raising, improves work efficiency.Pre-ballast peace platform bears storm load when, there is the latch of two-layer rotating ring beam together
Undertake load, substantially reduce the load suffered by single latch, improve the safety of platform, and reliability.This practicality is new
Type compensate for the longitudinal and transverse problem of inclining of hull caused under platform pitching pile holding state due to sea bed injustice, available upper and lower rotating ring beam
Oil cylinder pressurize is adjusted supporting.
