Jack-up drilling rig manufacturing tooling and manufacturing method

Abstract

The invention relates to a self-elevating drilling platform manufacturing tool and a manufacturing method. The production tool has a platform body, and the bottom surface of the platform body is welded with six ear seats arranged in three rows and two rows according to the size of the welding position of the six upper columns of the jack-up drilling platform on the platform. The connecting holes of each ear seat are The overall machining is performed by installing the platform body on the machine tool. When the jack-up drilling platform is manufactured, the manufacturing tooling is supported by brackets, and the manufacturing tooling is respectively hinged to the upper and lower columns. After adjusting the level of the reference level of the manufacturing tooling, the characteristics of gravity are used to ensure the perpendicularity of the axis of each column to the reference level. The six upper columns and the six lower columns are respectively spot-welded by a plurality of tie bars to form the upper and lower column rigid bodies, and the upper and lower column rigid bodies are respectively welded with the platform and the bottom plate to form the platform body and the base. The self-elevating drill floor produced by the application of the invention has strong bearing capacity, good rigidity and free lifting, and the production method of the invention has the advantages of high working efficiency and low production cost.

Description

technical field [0001] The invention relates to the manufacturing technology of large-scale structural parts of petroleum machinery and equipment, in particular to a jack-up drilling platform manufacturing tool and a manufacturing method. Background technique [0002] Oil skid rig self-elevating drilling rigs have two structures: rotary type and telescopic type. They are large structural parts, and the size can generally reach 6m×3m×6m (length×width×height), which can bear drilling working load and self-weight load. Both the rotary drill floor and the telescopic drill floor are connected by the platform body and the base. figure 1 , figure 2 , image 3 Shown is a schematic diagram of the structure of the rotary drilling platform. figure 1 It is a schematic diagram of the rotary-elevating drilling floor when it is in a low position, and it is in a non-working state. The low position of the platform is for the convenience of transportation. figure 2 It is a schematic dia...
