Abstract

The invention provides an external hoisting system for triangular truss legs, which comprises a leg body and a hoisting beam, wherein the leg body comprises at least three chords arranged in a horizontal direction, the hoisting beam is mounted on any chord, moreover, the hoisting beam is located in a direction which is perpendicular to the chord and extends toward the outer side of the leg body, and both ends of the hoisting beam are respectively provided with a hoisting hole for cooperating with a hook of a gantry crane. The hoisting system can carry out hoisting within a range from 10m to 20m higher than a hoisting beam of the gantry crane, thus increasing the hoisting efficiency of the gantry crane and reducing the corresponding cost of off-shore floating crane operation and the corresponding construction cost.

Description

technical field [0001] The invention relates to the field of pile leg manufacturing, in particular to a triangular truss type pile leg external hoisting device. Background technique [0002] The truss-type pile legs are composed of main chord tubes located at the three apexes of the equilateral triangle and diagonal bracing tubes in the plane where two adjacent main chord tubes are located. The main chord is a circular pipe structure, and the pin holes of the same size are set at equal intervals. When the platform is raised and lowered, the hydraulic cylinder of the lifting device drives the pins to insert into the pin holes, and the expansion and contraction of the oil cylinder drives the platform to rise and fall. The platform goes up and down continuously. The height of the pile legs of this type of platform is determined by the water depth of the design sea area, usually between 90 meters and 160 meters. The shipyard construction adopts large-scale gantry cranes for hoi...
