Description

A kind of double-layer movable ring beam hydraulic bolt formula continuous lowering or hoisting gear of cylinder spud leg
Technical field
The present invention relates to ocean platform jack up lowering or hoisting gear, particularly to a kind of double-layer movable ring beam hydraulic bolt formula continuous lowering or hoisting gear of cylinder spud leg.
Background technology
Current hydraulic bolt formula self-elevating ocean platform mainly has, fixed ring girder construction.Relative to double-layer movable ring beam structure, the simple in construction of dynamic, fixed ring beam, it is simple to manufacturing processing, but have wait this process of oil cylinder backhaul in lifting platform process, lifting process be discontinuously lift, and average rising or falling speed is relatively low, causes that working platform is inefficient.Platform is at pre-ballast with when bearing storm load, and load is very big, now can only lean on one layer of latch bearing load of fixed ring beam, and on average relatively big to the load of a latch, danger coefficient is higher.After platform is lifted to working depth, fixed ring beam can only be leaned on to fix, if sea bed injustice may result in the longitudinal and transverse problem such as incline of hull, the safety of platform be affected.
Summary of the invention
The invention aims to overcome above deficiency, it is provided that a kind of simple in construction, double-layer movable ring beam hydraulic bolt lowering or hoisting gear safe and reliable, easy to use.
The purpose of the present invention is achieved through the following technical solutions: a kind of double-layer movable ring beam hydraulic bolt formula continuous lowering or hoisting gear of cylinder spud leg, including circle spud leg, described cylinder spud leg is cased with wedge bracket, upper rotating ring beam and lower rotating ring beam, rotating ring beam is provided with on described rotating ring beam bolt mechanism and on connect bearing pin, what be provided with on described in lower rotating ring beam bolt mechanism and lower rotating ring beam connecting pin rotating ring beam on described lower rotating ring beam is arranged over upper strata oil cylinder, it is provided with between described upper strata oil cylinder and described wedge bracket and is connected otic placode, described lower rotating ring beam be arranged over lower floor's oil cylinder, it is connected otic placode under being provided with between described lower floor oil cylinder and described wedge bracket.
Further improvement of the present invention is in that: be arranged over upper strata hoist cylinder at upper rotating ring beam, and individual upper strata hoist cylinder is distributed in the circumferencial direction of described wedge bracket.
Further improvement of the present invention is in that: be arranged over lower floor hoist cylinder at lower rotating ring beam, and individual lower floor hoist cylinder is distributed in the circumferencial direction of described wedge bracket.
The present invention compared with prior art has the advantage that
When lifting without waiting for the time of oil cylinder backhaul, rising or falling speed is greatly improved, and improves work efficiency;
When pre-ballast peace platform bears storm load, there is the latch of two-layer rotating ring beam to undertake load together, substantially 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 the structural representation of the present invention;
Number in the figure: connect connection otic placode under otic placode, 11-lower floor oil cylinder, 12-under 1-cylinder spud leg, 2-wedge bracket, 3-upper rotating ring beam, 4-under rotating ring beam, 5-upper rotating ring beam bolt mechanism, the upper rotating ring beam connecting pin of 6-, 7-under rotating ring beam bolt mechanism, 8-on rotating ring beam connecting pin, 9-upper strata oil cylinder, 10-.
Detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
As Fig. 1 illustrates a kind of embodiment of the present invention a kind of double-layer movable ring beam hydraulic bolt formula continuous lowering or hoisting gear of cylinder spud leg, including cylinder spud leg 1 is cased with wedge bracket 2, upper rotating ring beam 3, lower rotating ring beam 4, described upper rotating ring beam 3 is provided with rotating ring beam bolt mechanism 5 and upper connection bearing pin 6, what described lower rotating ring beam 4 was provided with described in lower rotating ring beam bolt mechanism 7 and lower rotating ring beam connecting pin 8 rotating ring beam 3 is arranged over upper strata oil cylinder 9, it is provided with between described upper strata oil cylinder 9 with described wedge bracket 1 and is connected otic placode 10, described lower rotating ring beam 4 be arranged over lower floor's oil cylinder 11, it is connected otic placode 12 under being provided with between described lower floor oil cylinder 11 with described wedge bracket 1;
Upper rotating ring beam is hinged by 4 oil cylinders and hull wedge bracket, and lower rotating ring beam is hinged by 4 oil cylinders and wedge bracket, and upper and lower rotating ring beam is respectively provided with 4 set bolt devices.
When peaceful, upper strata oil cylinder is in shortest route state, and upper latch inserts spud leg hole, spud leg hole extracted by lower latch, and upper strata oil cylinder stretches out simultaneously lower floor's oil cylinder retraction platform and is lifted, until upper strata oil cylinder reaches Chang lower floor oil cylinder and is reduced to the shortest after a pitch, lower latch inserts, and upper latch is extracted.Lower floor's hoist cylinder stretches out simultaneously upper strata oil cylinder retraction platform and is lifted, 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, and above-mentioned action reaches the purpose of peaceful so repeatedly.When dropping platform, lower latch inserts in spud leg hole, spud leg hole extracted by upper latch, lower floor's 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 into the shortest upper strata oil cylinder and reaches the longest, upper latch inserts, and lower latch is extracted, and upper strata oil cylinder retraction lower floor's oil cylinder simultaneously stretches out platform and does down maneuver, until after a pitch, upper strata oil cylinder is reduced to Duan lower floor oil cylinder and reaches the longest, and lower latch inserts, and upper latch is extracted, above-mentioned action repeatedly, completes the purpose that platform declines;When the pre-ballast of storm, pile pulling can by upper and lower layer oil cylinder synchronization of jacking up, shunk piling and pile pulling.
Double-layer movable ring beam structure of the present invention is when lifting without waiting for the time of oil cylinder backhaul, and rising or falling speed is greatly improved, and improves work efficiency.When pre-ballast peace platform bears storm load, there is the latch of two-layer rotating ring beam to undertake load together, substantially reduce the load suffered by single latch, improve the safety of platform and reliability.The present invention compensate for the longitudinal and transverse problem of inclining of hull caused under platform pitching pile holding state due to sea bed injustice, and available upper and lower rotating ring beam oil cylinder pressurize is adjusted supporting.
