Description

A kind of truss-like hydraulic bolt lowering or hoisting gear
Technical field
The utility model relates to ocean platform jack up lowering or hoisting gear, particularly a kind of truss-like hydraulic bolt lowering or hoisting gear.
Background technology
Self-elevating ocean platform pile leg structure mainly contains two kinds of case type and truss-likes, and case type application is wider. With respect to truss framed leg, case type simple in structure, is convenient to manufacture processing, but is subject to the Area comparison of such environmental effects large, and can only work in shallow sea. Truss-like can be more than 60m deep ocean work, therefore truss-like often use on deep ocean work installation ship or offshore drilling platforms and be pinion and-rack. General truss formula spud leg is pinion and-rack structure, and service behaviour is unstable, has potential safety hazard.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, and a kind of truss-like hydraulic bolt lowering or hoisting gear simple in structure, safe and reliable, easy to use is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of truss-like hydraulic bolt lowering or hoisting gear, comprise wedge bracket, wedge bracket is provided with English truss formula spud leg, on English truss formula spud leg, be evenly distributed with three main chord tubes, the both sides of every 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, between upper strata oil cylinder and wedge bracket, be provided with and be connected otic placode, the top of sliding block is provided with lower floor's oil cylinder, under being provided with between lower floor's oil cylinder and wedge bracket, be connected otic placode.
Further improvement of the utility model is: the top of top shoe is provided with two upper strata oil cylinders, and two upper strata oil cylinders are placed in respectively the both sides of wedge bracket.
Further improvement of the utility model 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 respectively wedge bracket both sides.
The utility model compared with prior art has the following advantages: the utility model has effectively reduced spud leg deadweight; avoid current to impact pile body; service behaviour is steady; under work and the various states of inoperative; there is multiple safety precautions; in the time that a latch lost efficacy, can utilize hydraulic system to carry out redistributing of power, ensure that platform is in descending operation and Offshore Operation safety. The utility model has made up the longitudinal and transverse problem of inclining of hull causing due to sea bed injustice under platform pitching pile holding state, can utilize the pressurize of upper and lower slide block oil cylinder to regulate support.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: connect otic placode under latch, 10-upper strata oil cylinder, the upper connection of 11-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 understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows a kind of embodiment of a kind of truss-like hydraulic bolt of the utility model lowering or hoisting gear, comprise wedge bracket 1, wedge bracket 1 is provided with English truss formula spud leg 2, on English truss formula spud leg 2, be evenly distributed with three main chord tubes, the both sides of every 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 respectively the both sides of wedge bracket 1, between upper strata oil cylinder 10 and wedge bracket 1, be provided with and be connected otic placode 11, the top of sliding block 5 is provided with lower floor's oil cylinder 12, under being provided with, is connected otic placode 13 between lower floor's oil cylinder 12 and wedge bracket 1.
Embodiment mono-
Top shoe is hinged by six oil cylinders and hull wedge bracket, and sliding block is hinged by six oil cylinders and wedge bracket, is respectively provided with six cover bolt devices on upper and lower slide block. In the time of peaceful, upper cylinder is in shortest route state, and latch inserts spud leg hole, lower latch is extracted spud leg hole, 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 so above-mentioned action reaches the object of peaceful repeatedly; While falling platform, lower latch inserts in spud leg hole, and upper latch is extracted spud leg hole, 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 lower latch is extracted spud leg hole, and oil cylinder is stretched to after a spud leg pitch, lower latch inserts spud leg hole, upper latch is extracted spud leg hole, and above-mentioned action repeatedly completes the object that platform declines; Can be by upper and lower oil cylinder synchronization of jacking up when the pre-ballast of storm, pile pulling, shunk piling and pile pulling.
Embodiment bis-
Top shoe is hinged by six oil cylinders and hull wedge bracket, and sliding block is hinged by six oil cylinders and wedge bracket, is respectively provided with six cover bolt devices on upper and lower slide block. When preparing to put stake peaceful time, upper and lower oil cylinder is in stretching out state, latch keeps inserting in spud leg hole, when action, upper latch is extracted, oil cylinder zero load bounces back to shortest route, same oil cylinder at present stretches out, by latch load transfer, spud leg is transferred, until stretch out long status, now go up latch and insert, lower latch is extracted, upper cylinder drives spud leg to cover a pitch as extend action, covers a pitch with oil cylinder zero load at present as retract action, and above-mentioned action reaches the object of peaceful continuous lifting so repeatedly; While falling platform, action is contrary.
The utility model has effectively reduced spud leg deadweight; avoid current to impact pile body; service behaviour is steady; under work and the various states of inoperative; there is multiple safety precautions; in the time that a latch lost efficacy, can utilize hydraulic system to carry out redistributing of power, ensure that platform is in descending operation and Offshore Operation safety. The utility model has made up the longitudinal and transverse problem of inclining of hull causing due to sea bed injustice under platform pitching pile holding state, can utilize the pressurize of upper and lower slide block oil cylinder to regulate support.
