Problems solved by technology

When the bolts are tightened, use a 0.05mm feeler gauge to check that 70% of the perimeter cannot be inserted between the cover plate and the flange plane. Some scattered parts allow the insertion depth of 0.05mm feeler gauge to be 10-15mm. The installation accuracy is very high, and the installation process Accuracy directly affects the use effect. At present, if the installation process accuracy wants to achieve the ideal state, it is time-consuming and labor-intensive, and the adjustment time and cost are high and very difficult.

Embodiment Construction

[0016] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0017] The present invention takes Offshore Oil 278 platform as an example. Before the installation starts, the on-site processing method of the mechanical power milling head after welding is adopted to ensure the accuracy of the flange plane on which the retractable propeller is installed. The value was measured using a laser flatness measuring device (Easy-Laser).

[0018] Step 1. On-site processing of the flange plane of the retractable thruster installation casing.

[0019] Step 1.1. The main body of the retractable thruster should be installed on the plane of the hull casing flange, and the flatness of the casing flange should be 0.508mm. When the bolts are tightened, use a 0.05mm feeler gauge to check that 70% of the circumference cannot be i...

Abstract

The invention provides a ship telescopic propeller installation process. The ship telescopic propeller installation process comprises steps that 1, a telescopic propeller installation containment wellflange plane is machined on site; 2, a telescopic propeller guide rod corner hanging box is mounted; 3, a V-shaped rail of a guide rail body is machined; 4, a telescopic propeller main body is mounted; 5, a V-shaped rail of the guide rail body is mounted; 6, a telescopic guide rod and a lifting hook of a telescopic propeller are mounted; and 7, telescopic propeller hydraulic oil and cooling waterpipelines, cables and a control signal system are mounted. The installation process is advantaged in that the installation process can be compatible with equipment of different types of manufacturers, installation process precision is high, the mounting and adjusting time is greatly saved, mounting efficiency is improved, cost is low, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a ship retractable thruster installation process. Background technique [0002] There are a lot of propeller process equipment for ships. Taking Offshore Oil 278 platform as an example, there are many different types of equipment from different manufacturers, and the degree of automation is high. The installation and commissioning process is complicated, involving many professional manufacturers, resulting in compatibility with different models of manufacturers. The equipment has very high requirements for its dynamic positioning system, and the accuracy of the installation process of its propeller directly affects the use effect of its positioning and other equipment. The plane of the surrounding well flange installed by the retractable propeller of the ship is processed on site, and the flatness requirement is 0.508mm. insert. When the bolts are tightened, use a 0.05mm ...
