Definitions
- the present invention relates to an elevating device producing the relative vertical displacements of the deck and the supporting feet of a mobile marine platform.
- the device according to the invention equips a marine platform intended for work at sea such as oil drilling.
- a marine platform consists of a horizontal bridge and vertical feet, the number of which is at least equal to 3. They are supported on the seabed so as to support the bridge.
- the platform can be brought by floatation to a determined site, the feet being raised. The feet are then lowered into the water until their soles rest on the seabed. The platform bridge is then raised above the water level by resting on the feet. The bridge and the platform legs are guided relatively using guide shoes. This guidance conditions the stability of the platform on its feet. Guidance is all the more effective the greater the distance between the lower and upper guide pads. A relatively large clearance is provided between each foot and the associated guide pads in order to allow normal operation and economical construction.
- the lifting devices which equip marine platforms to ensure the relative movements of the deck and the feet are various.
- Some lifting devices are of the pinion and rack type.
- US Patents 3,183,676 and 2,924,077 describe devices of this kind.
- Each of these devices comprises racks which are integral with the feet and mesh with drive pinions.
- These drive pinions are mounted on chassis which are integral with the bridge.
- the guiding of each foot must therefore be carried out in a precise manner using guiding members mounted, above the pinions, on a superstructure integral with the bridge.
- These guide members must be separated from the guide members located at the level of the bridge by a relatively large distance.
- the feet and the racks can undergo significant deformations between the guide assemblies. Under these conditions, the teeth of the pinions and racks no longer mesh correctly.
- the present invention relates to an elevating device of the pinion and rack type in which the teeth mesh correctly even if the racks undergo deformations.
- the device has the advantage of being isostatic. It avoids the use, above the drive pinions, of guide shoes linked to the platform bridge. It allows the feet to oscillate, avoiding overloads on the gables when the platform is kept in the working position.
- the device according to the invention is suitable for a platform comprising a bridge supported by feet and it. comprises on the one hand racks, cut in uprights fixed to the feet and on the other hand locomotor blocks which each comprise a chassis fitted with pinions driven in rotation by motors and meshing on said racks, the bridge being suspended from each block locomotor by a suspension system comprising an articulation connecting to the locomotor block and it is essentially characterized in that the articulation connecting to the locomotor block is substantially located in the vertical plane of symmetry of the upright containing the longitudinal axis of the foot and that each locomotor unit chassis is connected to at least one other locomotor unit chassis by at least three horizontal tie rods located on either side of said plane of symmetry.
- Figure 1 is a front view of an embodiment of the lifting device comprising two locomotor units associated with a foot of the platform.
- FIG. 2 is a view from the left of FIG. 1.
- FIG. 3 is a top view in section, along the line A-A, of FIG. 1.
- Figure 4 is a top view of a second embodiment of the lifting device comprising three locomotor units associated with a foot of the platform.
- FIG. 5 is a front view of an embodiment perfecting that of FIG. 1.
- FIG. 6 is a section along BB of FIG. 5.
- Figure 7 is a variant of Figure 5.
