Hoisting structure for oil field pry block

Abstract

The invention relates to a hoisting structure for an oil field pry block. The hoisting structure comprises a pry block and slings and is characterized in that hoisting bolt holes in vertical directions are arranged at four end corners of the pry block; a hoisting system connected with the pry block is arranged above the pry block and comprises a cover type connection frame which comprises four vertical columns corresponding to the four end corners of the pry block, bolt connection holes corresponding to the hoisting bolt holes are opened in column base boards of the vertical columns, upper ends of the adjacent vertical columns are fixed and connected through transverse beams or longitudinal beams, and hoisting lug boards are arranged at column top ends of the vertical columns; and the number of the slings corresponds to that of the hoisting lug boards, the lower ends of the slings are connected with the hoisting lug boards, and the upper ends of the slings are connected with a crane hoisting hook. A crane hoists the slings connected with the connection frame directly to hoist the pry block. The vertical columns are placed at four corners of the pry block, and the installation space above the pry block is not occupied, so that the hoisting structure is applicable to hoisting of various pry blocks, and the structure is stable and reliable.

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 main equipment, the skid needs to be hoisted to the platform for structural assembly after the construction is completed. [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 the lifting point. The hook of the crane can be hoisted directly by hooking the lifting point. The defect of this kind of hoisting stru...

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 affecting the spatial arrangement on the skid or causing the The arranged equipment or other components collide, so this kind of hoisting structure has certain limitations and cannot be applied to hoisting of all skids
