Hoisting tooling and hoisting method of hydraulic submersible pump

Abstract

The invention discloses a hoisting tool and hoisting method of a hydraulic submersible pump, belonging to the field of ship liquid cargo loading and unloading systems. The power transmission pipe of the hydraulic submersible pump is divided into a first transmission pipe and a second transmission pipe. The hoisting plate connects the first flange and the second flange on the first transfer pipe to hoist the first transfer pipe into the liquid cargo tank. The first flange and the second flange are interposed between the hoisting plate and the first support plate, realizing the support positioning of the first support plate and the second support plate on the deck of the first flange and the second flange, Ensure that the position of the first transfer pipe is installed accurately. The lifting plate is removed, the second transmission pipe is hoisted, and the second transmission pipe is connected to the first flange and the second flange through the connection space between the first support plate and the second support plate. Remove the first support plate and the second support plate, lift the second transfer pipe into the liquid cargo tank and fix the second transfer pipe and the deck. Ensure that the hydraulic submersible pump is hoisted in sections to reduce the bending problem caused by the shaking of the power transmission pipe when it is too long.

Description

Technical field [0001] The present invention relates to the field of ship-free loading and unloading systems, and more particularly to hoisting tooling and lifting methods of hydraulic submarine pumps. Background technique [0002] Hydraulic potubes are often used to deliver liquid goods in the liquid cargo tank of the ship to the liquid cargo. When the hydraulic submerged pump is installed onto the ship, the pump head of the hydraulic potential pump is connected to the power transmission tube, and then the hydraulic potter pump is hailed to the deck of the ship, the crane controls the hydraulic potential pump The potential pump mounting hole on the deck extends into the liquid cargo tank under the deck of the ship, wherein the power transmission tube includes a plurality of pipes connected to the coaxial. [0003] However, the above mode is only suitable for a hydraulic potter pump mounting the overall length of less than 15 meters. For some hydraulic potential pumps having a to...

Problems solved by technology

[0003] However, the above methods are only suitable for installing hydraulic submersible pumps with an overall length of less than 15 meters. For some hydraulic submersible pumps with an overall length of more than 15 meters, the overall length of the hydraulic submersible pump is too long to When hoisting and installing a hydraulic submersible pump over 15 meters, it is easy to cause the power transmission pipe of the hydraulic submersible pump to bend due to shaking of the hydraulic submersible pump, and the possibility of damage to the hydraulic submersible pump during installation is high
