Abstract
The invention relates to an offshore oil drilling platform, in particular to a column type ocean platform crane. The lower end of a samson post of the column type ocean platform crane is connected with a pedestal; a rotary table sleeves the pedestal and is meshed with the pedestal by a gear; the rotary table can freely rotate around the pedestal; a lower bearing is mounted between the samson post and the rotary table; a portal sleeves the outer side of the samson post; an upper bearing is mounted between the samson post and the inside of the upper end of the portal; the lower end of the portal is connected to the rotary table by a pin shaft; a mechanical room and a control room are arranged on the rotary table; and the rotary table is connected with a cantilever crane. The column type ocean platform crane has the advantages that the safety factor is high; the bearing and wind loading capabilities are strong; the use requirement can be met under a severe working condition; the load is large; the speed is rapid; the efficiency is high; the continuous and frequent operation can be realized; a common hand tool is used for completing the examination and maintenance operation of a rotation supporting system; the maintainability and corrosion resistance are high; the structure is simple; the failure rate is low; the installation is convenient; and the work of carrying, installing and disassembling apparatuses and the like can be conveniently carried out within a range.
Description
Technical field:
The present invention relates to a kind of offshore drilling platforms, particularly a kind of pillar ocean platform crane.
Background technology:
The in-depth utilized petrol resources exploitation along with the mankind and minimizing by land, oil-gas exploration and development proceeds to ocean by land gradually, the spring of platform is welcome development.In extra large work equipment manufacturing field, marine engineering hoisting equipment plays important role.Different with general land hoisting crane, marine purposes hoisting crane is generally fixed in ship platform, and the sport of platform itself produces strong impact to load movement.In operation, offshore crane can with wave pitching, rolling and heave, and these motions will cause load to swing, and particularly in lifting process, this type games of platform easily causes the load of having sling again to be bumped against with deck, and then threatens the safety of operation.It is different with the operative norm of land hoisting crane, due to sea bad environments so the safety factor of ocean platform crane employing is generally at 10 times, and the safety factor that land hoisting crane generally adopts be 2-3 doubly, simultaneously its safe reliability, maintainability, can wind resistance and corrosion stability require all very high.But current used hoisting crane all can not meet the demands.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of pillar ocean platform crane, the arrangement achieves safety factor high, and carrying wind loading rating is strong, can meet bad working environments to use, load is large, and speed is fast, efficiency is high, can work continuously, frequently, use common hand power tool just can complete inspection and the upkeep operation of revolving support system, maintainability, corrosion stability are high, structure is simple, failure rate is low, easy for installation, facilitate the carrying out of the work such as scope interior carrying, Assembly &Disassembly equipment.Overcome existing crane safety coefficient low, maintainability, can wind resistance and the low deficiency of corrosion stability.
The technical solution used in the present invention is: a kind of pillar ocean platform crane, comprises samson post, turntable and pedestal; Samson post lower end connects pedestal, turntable is sleeved on pedestal and also and between pedestal passes through gears meshing, turntable can rotate freely around pedestal, between samson post and turntable, lower bearing is installed, outside samson post, is set with door frame, between samson post and inside, door frame upper end, upper bearing is installed, door frame lower end by pinned connection on turntable, turntable is provided with mechanical room and control cabin, turntable is connected with jib, and jib outer end is connected with main hook and auxiliary hook.
The invention has the beneficial effects as follows: safety factor of the present invention is high, carrying wind loading rating is strong, can meet bad working environments and use, load is large, speed is fast, and efficiency is high, can work continuously, frequently, use common hand power tool just can complete inspection and the upkeep operation of revolving support system, maintainability, corrosion stability are high, and structure is simple, failure rate is low, easy for installation, facilitate the carrying out of the work such as scope interior carrying, Assembly &Disassembly equipment.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
As shown in Figure 1, a kind of pillar ocean platform crane, comprises samson post 1, turntable 4 and pedestal 5; Samson post 1 lower end connects pedestal 5, turntable 4 is sleeved on pedestal 5 and also and between pedestal 5 passes through gears meshing, turntable 4 can rotate freely around pedestal 5, lower bearing 7 is installed between samson post 1 and turntable 4, outside samson post 1, is set with door frame 2, between samson post 1 and inside, door frame 2 upper end, upper bearing 6 is installed, door frame 2 lower end by pinned connection on turntable 4, turntable 4 is provided with mechanical room 3 and control cabin 8, turntable 4 is connected with jib 9, and jib 9 outer end is connected with main hook 10 and auxiliary hook 11.
Upper bearing 6 mainly bears the gravity (axial force) of pulling force (diametral load) and the hoisting crane rotating part (comprising load) passed over by variable-amplitude steel wire rope.Lower bearing 7 mainly bears and passes the thrust (diametral load) of coming and the friction force rotating generation by jib 9.Two bearings itself do not bear capsizing moment, and capsizing moment is born by samson post 1 substantially, as long as samson post 1 does not fall, hoisting crane would not topple.Optimize the condition of toppling like this, what afterbody can be made to design is very little, and safety and maintainability are all good than common ramp bearings.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
