Mounting method for middle support of liquid cargo pump tubular column

Abstract

The invention discloses a liquid cargo pump tubular column middle support installation method. The liquid cargo pump tubular column middle support installation method comprises the following steps that S1, at the slipway stage, the center position of a liquid cargo pump tubular column in an oil suction well is marked according to the design requirement, and a mark is made; s2, arranging a total station at a proper position at the bottom of the cargo hold; s3, marking a vertical datum line on the transverse bulkhead by using the total station and taking the center of the oil suction well as a datum point, and marking; s4, a plurality of first horizontal datum lines are marked on the transverse bulkhead by using the total station and taking the center of the oil suction well as a datum point, the first horizontal datum lines are marked, and the first horizontal datum lines intersect with the vertical datum lines; and S5, according to the first horizontal datum line, each middle supporting and rooting support is sequentially welded to the transverse bulkhead, and two connecting rods are fixedly connected to each middle supporting and rooting support. The problems that in the prior art, an intermediate supporting rooting support is difficult to install, and the installation precision cannot be guaranteed are solved.

Description

Technical field [0001] The present invention relates to the field of shipbuilding, in particular to a liquid-cargo pump pipe string intermediate support installation method. Background [0002] The intermediate support of the liquid cargo pump pipe string of the refined oil tanker is arranged in the liquid cargo compartment, and the rooting bracket needs to be welded on the tank bulkhead, the rooting bracket is fixed to the liquid cargo pump pipe column through two connecting rods, in order to ensure the verticality of the liquid cargo pump pipe string, the angle of the intermediate support and the liquid cargo pump installation platform is required to be no more than 5 °, the current intermediate support is installed after the installation of the liquid cargo pump, and the liquid cargo pump is installed after the ship is launched, but when the ship is floating after the ship is launched, the operation is more difficult, and the side wall of the cabin needs to be specially paint...

AI Technical Summary

Problems solved by technology

[0002] The intermediate support of the liquid cargo pump string of the product tanker is arranged in the liquid cargo tank, and the rooting bracket needs to be welded on the trough bulkhead, and the rooting bracket fixes the liquid cargo pump string through two connecting rods. In order to ensure the vertical The angle between the intermediate support and the liquid cargo pump installation platform is required to be no more than 5°. At present, the intermediate support is installed after the liquid cargo pump is installed, and the liquid cargo pump is installed after the ship is launched. However, after the ship is launched, the ship In the floating state, the operation is more difficult, and the side wall of the cabin needs to be specially painted, and it is impossible to install a total station for positioning without damaging the paint, so the installation accuracy of the intermediate support is difficult to guarantee
