Description

A kind of continuous lifting gear of double-layer movable ring beam hydraulic bolt formula cylinder spud leg
Technical field
The present invention relates to ocean platform jack up lifting gear, more particularly to a kind of double-layer movable ring beam hydraulic bolt formula cylinder The continuous lifting gear of 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, Structure that is dynamic, determining ring beam is simple, processes, but have during lifting platform and wait for this process of oil cylinder backhaul, rises convenient for manufacture Drop process is discontinuously lifting, and average lifting speed is relatively low, causes working platform less efficient.Platform is in pre- ballast and bears storm During load, load is very big, can only lean at this time and determine one layer of bolt of ring beam and bear load, and the average load to a bolt is larger, Danger coefficient is higher.After platform is lifted to working depth, it can only lean on and determine ring beam and fix, if sea bed injustice may result in hull Longitudinal and transverse the problems such as inclining, affects to the safety of platform.
Invention content
More than overcoming the shortcomings of, provide a kind of simple in structure, safe and reliable, easy to use Double-layer movable ring beam hydraulic bolt lifting gear.
The purpose of the present invention is achieved through the following technical solutions:A kind of double-layer movable ring beam hydraulic bolt formula cylinder spud leg connects Falling unit of continuing rising, including circle spud leg, be cased on the cylinder spud leg wedge bracket, on rotating ring beam and lower rotating ring beam, on described Rotating ring beam is equipped with upper rotating ring beam bolt mechanism and upper connection axis pin, and lower rotating ring beam bolt mechanism is equipped on the lower rotating ring beam Upper strata oil cylinder is equipped with the top of rotating ring beam upper described in lower rotating ring beam connecting pin, is set between the upper strata oil cylinder and the wedge bracket There is upper connecting ear plate, the top of the lower rotating ring beam is equipped with lower floor's oil cylinder, is equipped between lower floor's oil cylinder and the wedge bracket Lower connecting ear plate.
Further improvement of the present invention is:A upper strata lifting cylinder, a upper strata lifting are equipped in the top of upper rotating ring beam Oil cylinder is distributed in the circumferencial direction of the wedge bracket.
Further improvement of the present invention is:Lower floor's lifting cylinder, a lower floor's lifting are equipped in the top of lower rotating ring beam Oil cylinder is distributed in the circumferencial direction of the wedge bracket.
Compared with the prior art, the present invention has the following advantages:
It greatly improves, improves work efficiency without waiting for the time of oil cylinder backhaul, lifting speed when lifting;
When pre- ballast peace platform bears storm load, the bolt for having two layers of rotating ring beam undertakes load together, significantly The load suffered by single bolt is reduced, improves safety and the reliability of platform;
It compensates for due to the longitudinal and transverse problem of inclining of hull caused by sea bed injustice under platform pitching pile holding state, using upper and lower Support is adjusted in rotating ring beam oil cylinder pressurize.
Description of the drawings:
Fig. 1 is the structural diagram of the present invention;
Figure label:The upper rotating ring beam bolt machine of rotating ring beam, 5- under the upper rotating ring beam of 1- cylinders spud leg, 2- wedge brackets, 3-, 4- Rotating ring beam connecting pin under rotating ring beam bolt mechanism, 8- under the upper rotating ring beam connecting pin of structure, 6-, 7-, 9- upper stratas oil cylinder are connected on 10- Otic placode, 11- lower floors oil cylinder, 12- lower connecting ear plates.
Specific embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should Embodiment is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As Fig. 1 shows a kind of a kind of reality of the continuous lifting gear of double-layer movable ring beam hydraulic bolt formula cylinder spud leg of the invention Mode is applied, including being cased with wedge bracket 2, upper rotating ring beam 3, lower rotating ring beam 4 on cylinder spud leg 1, the upper rotating ring beam 3 is equipped with upper dynamic Ring beam bolt mechanism 5 and upper connection axis pin 6, the lower rotating ring beam 4 are connected equipped with lower rotating ring beam bolt mechanism 7 with lower rotating ring beam The top of upper rotating ring beam 3 is equipped with upper strata oil cylinder 9 described in pin 8, and upper connection is equipped between the upper strata oil cylinder 9 and the wedge bracket 1 Otic placode 10, the top of the lower rotating ring beam 4 are equipped with lower floor's oil cylinder 11, are equipped between lower floor's oil cylinder 11 and the wedge bracket 1 Lower connecting ear plate 12;
Upper rotating ring beam is hinged by 4 oil cylinders with hull wedge bracket, and lower rotating ring beam is hinged by 4 oil cylinders with wedge bracket, 4 sets of bolt devices are respectively provided on upper and lower rotating ring beam.
When peaceful, upper strata oil cylinder is in shortest route state, and upper bolt is inserted into spud leg hole, and lower bolt extracts spud leg Hole, upper strata oil cylinder stretches out lower floor's oil cylinder retraction platform simultaneously and is lifted, until upper strata oil cylinder reaches longest lower floor after a pitch Oil cylinder is reduced to most short, lower bolt insertion, upper bolt extraction.Lower floor's lifting cylinder stretches out upper strata oil cylinder retraction platform simultaneously and is lifted It rises, upper strata oil cylinder is reduced to Duan lower floors oil cylinder and reaches longest after a pitch, and upper bolt is inserted into, and lower bolt is extracted, so Above-mentioned action achievees the purpose that peaceful repeatedly.When dropping platform, lower bolt is inserted into spud leg hole, and upper bolt extracts spud leg hole, under Layer oil cylinder upper strata oil cylinder simultaneously of retracting stretches out platform and does lowering action, until after a pitch, lower floor's oil cylinder is retracted on most short Layer oil cylinder reaches longest, and upper bolt is inserted into, and lower bolt is extracted, and upper strata oil cylinder is retracted while lower floor's oil cylinder stretches out platform and does and declines Action, until after a pitch, upper strata oil cylinder is reduced to Duan lower floors oil cylinder and reaches longest, and lower bolt is inserted into, and upper bolt is extracted, The purpose that platform declines is completed in above-mentioned action repeatedly;Upper and lower layer oil cylinder synchronization of jacking up, receipts can be passed through when the pre- ballast of storm, pile pulling Piling and pile pulling are completed in contracting.
Double-layer movable ring beam structure of the present invention carries significantly when lifting without waiting for the time of oil cylinder backhaul, lifting speed Height improves work efficiency.When pre- ballast peace platform bears storm load, the bolt for having two layers of rotating ring beam undertakes together Load substantially reduces the load suffered by single bolt, improves safety and the reliability of platform.The present invention compensates for Due to the longitudinal and transverse problem of inclining of hull caused by sea bed injustice under platform pitching pile holding state, using upper and lower rotating ring beam oil cylinder pressurize Support is adjusted.
