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

Abstract

The invention discloses a lifting tooling for a hydraulic immersed pump and a lifting method and belongs to the field of ship liquid cargo handling systems. A power transmission pipe of the hydraulicimmersed pump is divided into a first transmission pipe body and a second transmission pipe body. A lifting plate is connected to a first flange and a second flange on the first transmission pipe bodyand lifts the first transmission pipe body into a liquid cargo tank. The first flange and the second flange are arranged between the lifting plate and a first supporting plate in a clamped manner, the first supporting plate and a second supporting plate support and position the first flange and the second flange on a deck, and it is guaranteed that the first transmission pipe body is mounted in an accurate position. The lifting plate is detached, the second transmission pipe body is lifted, and connection between the second transmission pipe body and the first flange & the second flange is achieved through a connecting space between the first supporting plate and the second supporting plate. The first supporting plate and the second supporting plate are detached, the second transmission pipe body is lifted into the liquid cargo tank, and the second transmission pipe body and the deck are fixed. It is guaranteed that the hydraulic immersed pump is lifted in a segmental mode, and the problem of bending caused by oscillating when the power transmission pipe is too long is relieved.

Description

technical field [0001] The invention relates to the field of ship liquid cargo loading and unloading systems, in particular to a hoisting tool and hoisting method of a hydraulic submersible pump. Background technique [0002] Hydraulic submersible pumps are often used to transport the liquid cargo in the cargo tank of the ship to the outside of the cargo tank. Usually, when installing a hydraulic submersible pump on a ship, the pump head of the hydraulic submersible pump is connected to the power transmission pipe, and then the hydraulic submersible pump is hoisted to the deck of the ship as a whole, and the crane controls the hydraulic submersible pump to wear The submersible pump installation hole on the deck extends into the liquid cargo tank under the deck of the ship for installation, wherein the power transmission pipe includes a plurality of coaxially connected pipes. [0003] However, the above methods are only suitable for installing hydraulic submersible pumps wit...
