The upper worm gear and worm lifter is linked with bearing lead screw which is connected with upper blocks, the gears of lower blocks are engaged with the gears of lift racks, the lower blocks is matched with the level guiding chute in sliding, two oblique planes of the upper blocks and the lower blocks are matched tightly, the level guiding chute is fixed on the upper of the lower worm gear and worm lifter, the lifting racks are fixed on the footing. The device has the advantages of good self-locking performance, good security performance, reliable locking, comfortable driving, simple structure and easy operation, the locking and the bearing can be combined into one unit, and it can bear the weight of the entire platform.
Description
Technical field
The present invention relates to a kind of self-elevating drilling rig locking device, be used for the locking after the self-elevating drilling platform lifting is located, belong to the drilling rig locking device field.
Background technology
Self-elevating drilling platform is made up of platform, spud leg and elevating mechanism, and platform can be equipped with rig, other plant equipment and living facilities along the spud leg lifting on the Platform Deck.The difference that the platform leg substructure is looked the seabed supporting capacity is divided two kinds of heavy pad and plug-in types.Adorn jacking system around the spud leg, mainly contain hydraulic pressure or electric gear rack-and-pinion, spud leg is transferred and is inserted the seabed during work, platform is raised to the trouble free service height that leaves the sea, and platform is locked, and unclamps locking device after the completion, platform is reduced to the sea, extract spud leg and also all mention, whole platform floats on the sea, is dragged to new well location by tugboat.Relied on mechanism's lockings such as pin in the past, the complex structure of this device, operating difficulties, labour intensity is big, and safety and reliability are all undesirable, and need locking and carry two cover mechanisms.
Summary of the invention
The objective of the invention is to have designed a kind of safe with deficiency for the shortcoming that overcomes above-mentioned prior art, locking is reliable, transmission freely, simple in structure, easy to operate, and locking and the self-elevating drilling rig locking device that unites two into one of carrying, thereby locking device can carry the weight of whole platform again.
The objective of the invention is to realize by following technical proposal:
Self-elevating drilling rig locking device, it is by the platform bearer body, last worm and gear hoist, the load screw mandrel, the load fairlead, last skewback, the vertically-guided groove, following skewback, horizontal guide slot, following worm and gear hoist, footing and lifter rack are formed, last worm and gear hoist top is fixed on platform bearer body inner top, the bottom connects the load screw mandrel by flange, there is the load fairlead load screw mandrel outside, the load fairlead is fixed on the vertically-guided groove top platform, load screw mandrel external screw thread and load fairlead screw-internal thread fit, load screw mandrel bottom connects by connecting flange goes up skewback, last skewback is the leg-of-mutton block of chamfer, the limit face of its right-angle side is slidingly matched with the vertically-guided groove that is fixed on the fluted body of supporting body inwall, the inclined-plane of hypotenuse is slidingly matched with the inclined-plane of the hypotenuse of following skewback, following skewback one side has the teeth that are meshed with the lifter rack teeth, the inclined-plane of the inclined-plane of the hypotenuse of opposite side and last skewback hypotenuse is slidingly matched, the groove of following skewback base and horizontal guide slot is slidingly matched, last skewback and following skewback two inclined-plane tight fits, horizontal guide slot is fixed on down worm and gear hoist top, following worm and gear hoist bottom is fixed on platform bearer body inner bottom part, and lifter rack is fixed on the spud leg.
But this locking device one or two or a plurality of being configured on the offshore boring island.
Since take technique scheme to make the present invention compared with the prior art have good self-locking property, good security performance, and locking is reliable, transmission freely, and is simple in structure, in light weight, easy to operate, lock and carry advantage and the effect that unites two into one and can carry the weight of whole platform.
Description of drawings
Fig. 1 is a structural representation of the present invention
The specific embodiment
Self-elevating drilling rig locking device, by shown in Figure 1, it is by platform bearer body (11), last worm and gear hoist (1), load screw mandrel (3), load fairlead (4), last skewback (6), vertically-guided groove (7), following skewback (8), horizontal guide slot (9), following worm and gear hoist (10), footing (12) and lifter rack (13) are formed, last worm and gear hoist top is fixed on platform bearer body inner top, the bottom connects the load screw mandrel by flange (2), last worm and gear hoist drives lifting with hydraulic motor or reducing motor, there is the load fairlead load screw mandrel outside, the load fairlead is fixed on (not shown) on the vertically-guided groove top platform, load screw mandrel external screw thread and load fairlead screw-internal thread fit, load screw mandrel bottom is by skewback in connecting flange (5) connection, skewback moved up and down on drive load screw mandrel moved up and down and drives when last worm and gear hoist rises, last skewback is the leg-of-mutton block of chamfer, the limit face of its right-angle side is slidingly matched with the vertically-guided groove that is fixed on the fluted body of supporting body inwall, the inclined-plane of hypotenuse is slidingly matched with the inclined-plane of the hypotenuse of following skewback, following skewback one side has the teeth that are meshed with the lifter rack teeth, the inclined-plane of the inclined-plane of the hypotenuse of opposite side and last skewback hypotenuse is slidingly matched, the groove of following skewback base and horizontal guide slot is slidingly matched, horizontal guide slot is fixed on down worm and gear hoist top, last skewback and following skewback two inclined-plane tight fits, assurance moves up and down synchronously, guarantee that teeth engagement Huaihe River is true, following worm and gear hoist bottom is fixed on platform bearer body inner bottom part, driving down by horizontal guide slot when hydraulic motor or reducing motor drive down the worm and gear hoist, skewback moves up and down, when skewback moves to teeth with position that the teeth of lifter rack are meshed instantly, restart and go up the work of worm and gear hoist, lifter rack is fixed on the spud leg.
But this locking device one or two or a plurality of configuration, two locking devices as shown in Figure 1 are balanced configuration, and same a plurality of locking devices are also configurable on identical platform.
The course of work:
During work, drive worm and gear hoist down by hydraulic motor or reducing motor (not shown), driving down by horizontal guide slot, skewback moves up and down.When skewback is moved upwards up to teeth with position that the lifter rack teeth are meshed instantly, start the last worm and gear hoist that drives by hydraulic motor or reducing motor (not shown), the load screw mandrel is moved down along the load fairlead by connecting flange.The load screw mandrel promotes to go up skewback and moves down along the vertically-guided groove, by ramp effect skewback locking is embedded in the lifter rack, thereby finishes locking action.
After locking is finished, because the good self-locking property of worm-and-wheel gear, sleeve mechanism will possess good reliable lock.
The weight of whole platform is by platform bearer body, load screw mandrel, load fairlead, last skewback, following skewback, lifter rack are delivered on the spud leg, so this device will be locked and carrying unites two into one, and carry the weight of platform, make structure simpler, the work safety and reliability.
