Oilfield skid block hoisting structure

Abstract

The invention relates to an oilfield skid block hoisting structure comprising a skid block and having the innovative characteristics as follows: a plurality of lifting eyes are formed on two edges of the skid block symmetrically; a hoisting system connected with the lifting eyes is arranged above the skid block; the hoisting system at least comprises a lifting beam and a plurality of branch slings; the lifting beam is arranged right above the skid block horizontally; the axes of the lifting beam is perpendicular to the two edges of the skid block, on which the lifting eyes are formed; the number of the branch slings corresponds to the number of the lifting eyes; and the lifting eyes on the same edge of the skid block are respectively connected with one end of the lifting beam close to the same edge through the branch slings. When the oilfield skid block hoisting structure is used, the lifting beam of the hoisting system is connected with a lifting hook of a loop wheel machine directly or indirectly, and the branch slings of the hoisting system are connected with the lifting eyes of the skid block so as to achieve hoisting. When the branch slings are connected with the lifting eyes, the lifting eyes on the same edge of the skid block are respectively connected with one end of the lifting beam close to the same edge through the branch slings, so that the branch slings are far away from a mounting plane of the skid block, the occupation of useful installation space on the upper end surface of the skid block can be reduced, and application range of the oilfield skid block hoisting structure can be widened.

Description

technical field [0001] The invention relates to an oilfield skid, in particular to an oilfield skid hoisting structure. Background technique [0002] In marine engineering, the module refers to the container block that the equipment and facilities of the whole system are assembled in the steel frame according to the technical requirements, and can be transported and hoisted as a whole. As a sub-module of each major equipment, the skid block needs to be hoisted to the platform for structural assembly after construction is completed, or assembled into modules together with structures, pipelines and other disciplines on land for overall hoisting and transportation. [0003] At present, the hoisting structure of the oilfield skid block is generally as follows: several lifting lugs are respectively arranged on both sides of the skid block, and each lifting lug is respectively connected with the lower end of the sling, and the upper end of the sling is connected with the hook at t...

AI Technical Summary

Problems solved by technology

The defect of this kind of hoisting structure is that when the slings are collected from the lifting lugs to the lifting point, the slings are inclined inward, which will occupy the space above the skid, thereby aff
