Abstract

The present invention provides a triangular truss type leg external hoisting device, which includes a leg body and a hanging beam, the leg body includes at least three chord edges arranged in the horizontal direction, and the hanging beam is installed with any one of the on the chord side, and the hanging beam is located in the direction perpendicular to the chord side and extending to the outside of the leg body, the two ends of the hanging beam are respectively provided with hooks for matching with the gantry crane. hanging hole. The hoisting device can realize hoisting beyond the range of 10m to 20m of the height of the gantry crane's hoisting beam, thereby improving the hoisting efficiency of the gantry crane, and saving the corresponding cost of offshore floating crane operations and corresponding construction costs.

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...
