Water riser pipe transferring system

Abstract

The invention relates to the field of marine drilling engineering equipment, in particular to a water riser pipe transferring system with effective guiding, the alignment time reducing and tilting accident avoiding functions, The transferring system comprises a rail assembly fixedly connected with the foundation, and further comprises a transferring trolley, wherein the transferring trolley is composed of a base movably connected with the rail assembly, a frame structure fixedly connected with the base, a speed reducer assembly fixedly connected with the base and centering guide movably connected with the frame structure; and the number of the centering guide is two, the two centering guide are arranged in parallel, and are perpendicular to the rail assembly. The transferring system is convenient to carry, the occupied area is small, the control displacement is more accurate, the working efficiency is improved, and the occurrence rate of safety accidents is reduced.

Description

technical field [0001] The invention relates to the field of marine drilling engineering equipment, in particular to a riser transfer system capable of effective guidance, reducing alignment time and avoiding tipping accidents. Background technique [0002] The riser is a unique tool for marine drilling, especially for deep-sea drilling. The deep-sea drilling system uses a large number of risers because of the large depth of seawater. Due to the weight of the riser, in order to improve the stability of the hull, it is necessary to reduce the overall riser. In the center, the riser is usually stored vertically. When using the riser, the riser needs to be moved from the riser storage area to the drill floor. After use, the riser needs to be moved from the drill floor to the riser storage area. , in order to efficiently and safely move the riser back and forth between the riser storage area and the drilling floor, usually the upper end of the riser is lifted by a crane, and the...

AI Technical Summary

Problems solved by technology

[0005] 1. The riser transport trolley in the prior art has an integrated structure, and the transport cost is relatively high;

[0006] 2. The trolley for moving the riser in the prior art is driven by a winch, and the winch occupies a large area;

[0007] 3. The trolley for moving the riser in the prior art is driven by the steel wire rope to move on the track, and the steel wire rope is in danger of breaking during the work;

[0008] 4. The riser transfer trolley in the prior art can only control the displacement of the riser through the gap between the riser and the transfer trolley;

[0009] 5. Since the riser transfer trolley in the prior art cannot fix one end of the riser, it cannot be used under severe working conditions such as when the sea waves are large, which reduces the working efficiency of the riser transfer trolley;

[0010] 6. The riser transfer trolley in the prior art has no anti-tipping mechanism when running on the track, and it is prone to tipping accidents under severe working conditions such as when the waves are large
