Lower connecting lug plates are arranged between the lower cylinders and the jacking frame. The lifting device has the advantages of simple structure, safety and reliability, and high convenience in use.
Description
Technical field
The present invention relates to ocean platform self lift type lifting gear, particularly a kind of truss-like hydraulic bolt lifting gear.
Background technology
Self-elevating ocean platform pile leg structure mainly contains case type and truss-like two kinds, and case type application is wider.Relative to truss framed leg, the structure of case type is simple, is convenient to manufacture processing, but large by the Area comparison of such environmental effects, and can only work in shallow sea.Truss-like can at the deep ocean work of more than 60m, and therefore truss-like is often used on deep ocean work installation ship or offshore drilling platforms and is pinion and-rack.General truss formula spud leg is pinion and-rack structure, and service behaviour is unstable, there is potential safety hazard.
Summary of the invention
The object of the invention is to overcome above deficiency, the truss-like hydraulic bolt lifting gear providing a kind of structure simple, safe and reliable, easy to use.
Object of the present invention is achieved through the following technical solutions: a kind of truss-like hydraulic bolt lifting gear, comprise wedge bracket, wedge bracket is provided with English truss formula spud leg, English truss formula spud leg is evenly distributed with three main chord tubes, the both sides of every root main chord tube are provided with directive slide track, on directive slide track, cover has top shoe and sliding block, top shoe is provided with upper pin hole, sliding block is provided with downside pin axis hole, the bottom of top shoe is inserted with latch, the bottom of sliding block is inserted with lower latch, the top of top shoe is provided with upper strata oil cylinder, upper strata oil cylinder is connected otic placode with being provided with between wedge bracket, the top of sliding block is provided with lower floor's oil cylinder, lower floor's oil cylinder be provided with between wedge bracket under be connected otic placode.
Further improvement of the present invention is: the top of top shoe is provided with two upper strata oil cylinders, and two upper strata oil cylinders are placed in the both sides of wedge bracket respectively.
Further improvement of the present invention is: the top of sliding block is provided with Liang Ge lower floor oil cylinder, and Liang Ge lower floor oil cylinder is placed in wedge bracket both sides respectively.
The present invention compared with prior art has the following advantages: the present invention effectively reduces spud leg deadweight; current are avoided to impact pile body; service behaviour is steady; under work and the various state of inoperative; there is multiple safety precautions; when a latch lost efficacy, hydraulic system can be utilized to carry out redistributing of power, ensure that platform was in descending operation and Offshore Operation safety.The longitudinal and transverse problem of inclining of hull that the present invention causes because sea bed is uneven under compensate for platform pitching pile holding state, can utilize the pressurize of upper and lower slide block oil cylinder to carry out adjustment and support.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Number in the figure: connect otic placode under latch, 10-upper strata oil cylinder, 11-connecting otic placode, 12-lower floor oil cylinder, 13-under 1-wedge bracket, 2-English truss formula spud leg, 3-directive slide track, 4-top shoe, 5-sliding block, 6-upper pin hole, 7-downside pin axis hole, the upper latch of 8-, 9-.
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 only for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows a kind of embodiment of a kind of truss-like of the present invention hydraulic bolt lifting gear, comprise wedge bracket 1, wedge bracket 1 is provided with English truss formula spud leg 2, English truss formula spud leg 2 is evenly distributed with three main chord tubes, the both sides of every root main chord tube are provided with directive slide track 3, on directive slide track 3, cover has top shoe 4 and sliding block 5, top shoe 4 is provided with upper pin hole 6, sliding block 5 is provided with downside pin axis hole 7, the bottom of top shoe 4 is inserted with latch 8, the bottom of sliding block 5 is inserted with lower latch 9, the top of top shoe 4 is provided with upper strata oil cylinder 10, upper strata oil cylinder 10 and lower floor's oil cylinder 12 all can be provided with two, two upper strata oil cylinders 10 and Liang Ge lower floor oil cylinder 12 are placed in the both sides of wedge bracket 1 respectively, be provided with between upper strata oil cylinder 10 with wedge bracket 1 and be connected otic placode 11, the top of sliding block 5 is provided with lower floor's oil cylinder 12, is connected otic placode 13 between lower floor's oil cylinder 12 with wedge bracket 1 under being provided with.
Embodiment one
Top shoe is hinged by six oil cylinders and hull wedge bracket, sliding block pass through six oil cylinders and wedge bracket hinged, upper and lower slide block is respectively provided with six cover bolt devices.When peaceful, upper cylinder is in shortest route state, and latch inserts spud leg hole, spud leg hole extracted by lower latch, and lift cylinder is retracted to shortest route, and latch is inserted, upper latch is extracted, sliding block lift cylinder extends, and platform is hoisted, until after a pitch, upper latch inserts, lower latch is extracted, and oil cylinder is retracted to shortest route, and above-mentioned action reaches the object of peaceful so repeatedly; When falling platform, lower latch inserts in spud leg hole, and spud leg hole extracted by upper latch, and oil cylinder drives sliding block to be retracted to a spud leg pitch, platform does down maneuver, upper latch inserts spud leg hole, and spud leg hole extracted by lower latch, after oil cylinder is stretched to a spud leg pitch, lower latch inserts spud leg hole, spud leg hole extracted by upper latch, repeatedly above-mentioned action, completes the object that platform declines; When the pre-ballast of storm, pile pulling by upper and lower oil cylinder synchronization of jacking up, shunk piling and pile pulling.
