Abstract

The invention provides a marine engineering submarine pipeline erecting device. The device comprises a supporting under-frame, a middle supporting plate, side supporting plates, buckling plates and bottom plates, wherein the top end of the supporting under-frame is movably connected with a middle supporting plate through spring columns, the side supporting plates are movably connected to the middle parts of the left side and the right side of the supporting under-frame through rotating shafts, buckling plates are movably connected to the top ends of the left side and the right side of the supporting under-frame, the bottom plates are welded to the left side and the right side of the bottom end of the supporting under-frame, upper flow guide plates are welded to the top ends of the left side and the right side of the supporting under-frame, lower flow guide plates are welded to the bottom ends of the left side and the right side of the support under-frame, guide holes are embedded in the middle parts of the left side and the right side of the support under-frame, the left side and the right side of the top end of the supporting under-frame are embedded with movable grooves, the middle of the movable grooves are fixedly connected with side spring columns, collecting chambers are embedded in the middle of the left end and the right end of the supporting under-frame, and anti-dropping elastic ropes are fixedly connected to the bottom ends of the middle of the collecting chambers. The device has the advantages that the structure is stable, the fixing capability is good, the ground grabbing force can be improved along with the increase of the potential flow, and the mounting and fixing operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of pipeline erection equipment, and in particular relates to an ocean engineering submarine pipeline erection device. Background technique [0002] Submarine pipeline erection is an important part of ocean engineering today. There are two main laying methods for submarine pipelines: one is the pipe dragging method, and the other is the pipe laying ship method. Sea and very shallow waters or short-distance sea pipes are laid offshore. [0003] The existing support equipment for submarine pipelines is mostly fixed with the seabed by brackets, so as to support the pipelines. However, during the long-term use of effective submarine pipeline supports, they are impacted by undercurrents on the seabed, which makes the submarine pipeline supports loose, thus failing to perform well. When encountering a large undercurrent, the support of the submarine pipeline will be impacted and separated from the seabed, causing ...
