Sealer device capable of being used for offshore floating transportation of pipe piles

Abstract

The invention discloses a sealer device capable of being used for offshore floating transportation of pipe piles, and belongs to the field of ocean engineering construction transportation. The sealerdevice comprises a sealing cavity body, a prismatic surface reversing cone, a hydraulic driver, an adjustable overhanging arm, a sealing rubber ring, a mechanical lock and a lifting arm; the sealing cavity body comprises a containing cavity cylindrical shell, a sealing top cover, a sealing bottom plate and a sealing sleeve; the prismatic surface reversing cone can only move along the axis direction in the sealing cavity body, after the prismatic surface reversing cone moves through the hydraulic driver, the prismatic surface reversing cone converts axial lifting force into thrust enabling theadjustable overhanging arm to overhang along the radial direction; and along with the overhanging of the adjustable overhanging arm along the radial direction, the sealing rubber ring is expanded outwards, the inner walls of the pipe piles are extruded tightly, and the sealing effect is achieved. According to the sealer device capable of being used for offshore floating transportation of the pipepiles, the traditional tugboat and barge pipe pile transportation mode can be changed, the transportation difficulty and cost are reduced, and the construction period is shortened; a certain adjustingrange is achieved, and sealing of pipe piles of different sizes can be adapted; and a locking function is achieved, and irreparable accidents caused by sealing failure can be prevented through the mechanical lock.

Description

technical field [0001] The invention belongs to the field of marine engineering construction and transportation, and in particular relates to a sealer device that can be used for offshore floating transportation of pipe piles. It is mainly used in the marine transportation of large-diameter pipe pile structures, including the transportation of offshore wind power pipe piles and large steel pipes on offshore platforms. Background technique [0002] my country has a vast sea area and rich marine resources. In order to develop offshore resources, since the offshore wind power project was launched in 2009, after more than ten years of exploration and accumulation, related technologies and industries have gradually matured. However, there are still many technical problems in the construction of offshore facilities, among which the transportation of large-diameter steel pipe piles is one of the problems. [0003] For the transportation of offshore wind power steel pipe piles, tu...
