Embodiment Construction

[0011] Referring to the accompanying drawings, it can be seen that the specific structure of the present invention is as described above: the suction anchor barrel top flange 21 welded on the top of the suction anchor 1 barrel, and the threaded steel ring 20 is welded on the suction anchor barrel top flange 21 at the same time. The inner side of the gear threaded cap 18 has a threaded outer welding gear, and cooperates with the T-type flange compression end 19. The hydraulic motor 9 drives the gear 13 to rotate through the drive shaft 12, and drives the gear threaded cap 18 to rotate, compresses the T-shaped flange pressing end 19 and the suction anchor bucket top flange 21, and seals the flange interface through the sealing ring 15 . During removal, the hydraulic motor 9 reverses, and the gear threaded cap 18 and the threaded steel ring 20 are disengaged, which can realize automatic release and removal.

[0012] The specific installation steps are:

Abstract

The invention provides a suction type hydraulic rotary flange mechanism. The mechanism includes a hydraulic drive mechanism and a rotating flange pressing two parts, hydraulic drive comprising: a hydraulic motor, shaft, drive gears, wherein the drive gear is welded to the drive shaft . Rotating flange includes: gear threaded caps, T-type flange, seals, steel ring, top barrel flange suction anchors, bolts, water pump flanges, of which the inside of the gear screw cap is threaded outer gear, steel ring welded to the top flange of suction anchors barrel, T-thread connection flange and the pump flange. By hydraulic motor forward drive gear drive gear screw cap, the pressing mechanism of the docking ring to complete the installation, hydraulic motor reverse rotation is completed automatically from the flange. The mechanism effectively improves the efficiency of underwater installation and simple structure of the organization, reduce the construction difficulty. Meanwhile, the structure can be reused for the next shift moved migrate offshore oil platform, saving costs and duration.

Description

technical field [0001] The invention relates to a hydraulic rotary flange mechanism for suction foundation installation. It belongs to the field of offshore oil engineering. Background technique [0002] The offshore oil platform is a crucial link in the development of oil and gas. At present, the foundation of the offshore oil platform has two structures: the steel pipe pile foundation and the suction anchor foundation. Steel pipe pile foundation The steel pipe pile foundation has the outstanding characteristics of large pile diameter, large number of piles, and long pile body. Therefore, professional ships are required for hoisting and diesel piling hammers. The foundation installation period is long and the cost is high. The suction anchor foundation is easy to install, and the suction anchor can be slowly penetrated into the seabed by pumping water to form a negative pressure difference between the inside and outside of the suction anchor. However, after the water pump...
