Abstract
The utility model discloses a self elevating drilling platform pile leg locking device, comprising a locking rack, a transverse drive device, a vertical drive device and a power unit. The locking rack, fitting with a column leg rack, is driven by the transverse drive device and the vertical drive device to mesh with or separate with the column leg rack. The transverse drive device and the vertical drive device, both arranged on the platform, are powered by the power unit. In the utility model, the locking rack is driven by the transverse drive device and the vertical drive device. The locking rack is separated with the column rack when the platform elevates and descends. The locking rack is meshed with the column rack when the platform needs to be positioned; thereby, the total weight of the platform is transferred to the utility model gradually.
Description
Technical field
The utility model relates to a kind of locking device that is used for pile legs of self-elevating drilling platform.
Background technology
In present self-elevating drilling platform, the tooth bar that extends up and down is installed on the spud leg of support platform, platform is provided with the elevating mechanism that is meshed with this tooth bar, comes lift platform by controlling this elevating mechanism.When lifting platform during to certain position, use limited block to snap onto in the tooth of tooth bar usually, thereby reach platform is positioned on this position.Yet, use not only inconvenient operation of limited block, and, make limited block slippage from tooth bar come out, thereby cause the generation of contingency owing to may occur engaging bad situation between the tooth of limited block and tooth bar.And this mode can't shift load from lifting motor, platform weight is all born by jacking system.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of pile legs of self-elevating drilling platform locking device, platform can be positioned on the spud leg more reliably.
A kind of pile legs of self-elevating drilling platform locking device of the present utility model comprises: locking rack, lateral driver device, vertical drive unit and power unit, locking rack and post leg tooth bar are suitable, locking rack is meshed or is separated with the spud leg tooth bar under the driving of described lateral driver device and vertical drive unit, described lateral driver device and vertical drive unit provide power by described power unit, and described lateral driver device and vertical drive unit are arranged on the platform.
Further, described lateral driver device and vertical drive unit are hydraulic cylinder, and described power unit is the Driven by Hydraulic Cylinder system.
The utility model locking rack is by lateral driver device and vertically drive unit driving, when lifting platform, locking rack and spud leg tooth bar are separated, when platform need be located, locking rack is meshed with post leg tooth bar, thereby the total weight of platform is transferred on the utility model locking device gradually.Installation of the present utility model and platform hull are one; so just the weight of platform is delivered to Ship Structure by this system; just no longer stressed with the tooth bar and the jacking system of jacking system engagement in the operation process of platform; adequately protected lifting gear and spud leg tooth bar make jacking system and spud leg tooth bar that be arranged longer application life.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises: locking rack 7, lateral driver device 2, vertical drive unit 3 and power unit 4,5, locking rack 7 is suitable with post leg tooth bar 1, locking rack 7 is meshed or is separated with spud leg tooth bar 1 under the driving of lateral driver device 2 and vertical drive unit 3, lateral driver device 2 and vertical drive unit 3 provide power by power unit 4,5 respectively, and lateral driver device 2 and vertical drive unit 3 are arranged on the platform 6.Wherein, lateral driver device 2 and vertical drive unit 3 can be hydraulic cylinder, and power unit 4,5 is the Driven by Hydraulic Cylinder system.According to circumstances, many cover the utility model can be set on platform 6, as shown in Figure 1, be symmetrical arranged a cover locking mechanism at every main shipboard tube.According to the situation of spud leg, whole platform 6 can 9 cover (not shown go out).
When the end of job of lifting ship, by lateral driver device 2 locking rack 7 is moved into, be meshed, after 18 all cover locking tooth bars are all in place with spud leg tooth bar 1, by discharging the moment of torsion of lifting motor, the total weight of platform is transferred on the utility model locking device gradually.So just the weight of platform is delivered to Ship Structure by this system; just no longer stressed with the tooth bar and the jacking system of jacking system engagement in the operation process of platform; lifting gear and spud leg tooth bar have adequately protected; make jacking system and spud leg tooth bar that be arranged longer application life, improved the stability of platform location simultaneously greatly.
Claims (2)
