Abstract
The invention relates to a self-elevating drilling platform locking system, in particular to a worm structure of the self-elevating drilling platform locking system. The worm structure comprises a box-shaped beam and a worm gear speed reducing box which is arranged in the box-shaped beam, the worm gear speed reducing box comprises a worm gear and a worm, and an included angle between axis of the worm and the side wall of the box-shaped beam is 45-65 degrees. The worm structure is compact in structure and sufficient in space utilization, and cost is saved.
Description
Technical field
The present invention relates to self-elevating drilling platform fastening system, be specifically related to a kind of self-elevating drilling platform fastening system worm structure.
Background technology
Self-elevating drilling platform is a kind of mobile ocean engineering platform being widely used in marine energy sources exploration and exploitation, arrives predetermined work place by barge traction.After suitable working depth adjusted to by working platform, by fastening system firmly fixing platform and spud leg, with the load when work of resisting or storm.
Gravity under this self-elevating drilling platform locking state transmits by following path: platform base → worm gear reducer → carrying screw rod → wedge → locking teeth block → spud leg → seabed.Carrying screw rod, wedge and locking teeth block are load bearing component.Worm gear reducer drives carrying screw rod and then realizes the locking of locking teeth block and spud leg.In traditional worm and gear mounting structure, worm gear and worm screw in space are 90 ° and arrange staggered engagement; The simultaneously connection plane of other component that is connected with same worm mechanism of worm screw, also in 90 ° of layouts.In self-elevating drilling platform fastening system, worm gear reducer is arranged in the box beam of offshore boring island, if still install worm screw by traditional mode, need the inner space increasing box beam, the drawback of such existence has: increase the volume of box beam and space utilization is unreasonable, and cost also increases thereupon in addition.
Summary of the invention
For prior art Problems existing, provide a kind of compact conformation and space utilization rational self-elevating drilling platform fastening system worm structure.
The technical solution used in the present invention is:
A kind of self-elevating drilling platform fastening system worm structure, comprise box beam and worm gear reducer, described worm gear reducer is arranged in described box beam, and described worm gear reducer comprises worm gear and worm screw, and the angle between the axis of described worm screw and the sidewall of described box beam is 45-65 degree.
As preferred version of the present invention, the angle between the axis of described worm screw and the sidewall of described box beam is 55 degree.
As preferred version of the present invention, also comprise carrying screw rod, arrange the motion thread matched with described carrying screw rod in the axis hole of described worm gear, described carrying screw rod is connected by described motion thread with described worm gear.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: compact conformation, space utilization is abundant, and has saved cost.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention will be further described.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
embodiment 1
As shown in Figure 1, the gravity under self-elevating drilling platform locking state transmits by following path: platform base → worm gear reducer 2 → carrying screw rod 5 → wedge, 7 → locking teeth block 8 → spud leg tooth bar 9 → spud leg → seabed.Carrying screw rod 5, wedge 7 and locking teeth block 8 are load bearing component.Worm gear reducer 2 drives carrying screw rod 5 indirectly make the engagement of locking teeth block 8 and spud leg tooth bar 9 or be separated, and then realizes the locking and separately of jack-up rig platform.
As shown in Figure 2, worm gear reducer 2 comprises the casing 6 of worm screw 3, worm gear 4 and reduction box, and worm screw 3 and worm gear 4 are all arranged in casing 6.
Worm gear reducer 2 is integrally provided in box beam 1, if by traditional worm screw mounting means, angle α between the axis 301 of worm screw 3 and the sidewall 101 of box beam 1 is just 90 degree, the longitudinal size arranging box beam 1 is like this just larger, the not compact and irrational drawback of space utilization of structure can be caused, for avoiding this situation, so worm screw 3 is deflected certain angle relative to the sidewall 101 of box beam 1.As shown in Figure 4, the angle α between the axis 301 of described worm screw 3 and the sidewall 101 of described box beam 1 is 55 degree.
As shown in Figure 3, also comprise carrying screw rod 5, arrange the motion thread of the band self-locking property matched with described carrying screw rod 5 in the axis hole of described worm gear 4, described carrying screw rod 5 is connected by described motion thread with described worm gear 4.
embodiment 2
As shown in Figure 5, the angle α between the axis 301 of described worm screw 3 and the sidewall 101 of described box beam 1 is 45 degree.Angle α is more little more saves longitudinal space.But angle can not be too small, too small meeting is interfered with other equipment in box beam, so be advisable to be not less than 45 degree.Embodiment 2 other guide is identical with embodiment 1, repeats no more.
embodiment 3
As shown in Figure 6, the angle α between the axis 301 of described worm screw 3 and the sidewall 101 of described box beam 1 is 65 degree.Angle is larger, and the longitudinal space that worm screw takies is larger.Angle is crossed senior general and is not had the effect of joint space-efficient, so be advisable to be not more than 65 degree.Embodiment 2 other guide is identical with embodiment 1, repeats no more.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
