Embodiment Construction

[0020] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0021] A method for installing a telescopic azimuth auxiliary propeller, comprising the following steps:

[0022] Step 1: If figure 1 As shown, the telescopic azimuth auxiliary thruster 1, also known as the telescopic rudder propeller, is installed on the hull section 2. Place the hull section 2 on a special bracket with a height of 3.5 meters and fix it firmly to prevent movement during equipment commissioning. Use the equipment to draw the midship line 3 of the hull section 2 and the FR141 rib line 4 of the installation site, and these two lines are used as the reference line for installation. Considering that the working length (longitudinal) of the telescopic rudder propeller is 2742mm, the obstacles at the installation site should be cleared to ensure that there are no obstacles in the area with a lon...

Abstract

The invention discloses a method for installing a telescopic full-rotation auxiliary thruster. The method includes the following steps of firstly, fixing a ship body in a segmented mode, drawing out a midship line and a rib position line, and removing obstacles; secondly, hanging the thruster to the installation position so that the distance between the bottom of the thruster and the plane of a base at the installation position can range from 30 mm to 35 mm; thirdly, adjusting the levelness and perpendicularity of the thruster and fixing the thruster; fourthly, fixing a guide part so that the numerical value of a gap between a guide frame of the thruster and the guide part can be smaller than 1mm; fifthly, marking the installation position with a positioning mark, recording positioning data, and then hanging the thruster away; sixthly, installing accessories at the installation position; seventhly, hanging the thruster to the installation position again, and fixing the thruster according to the positioning data. According to the method, the segmented internal pre-assembly and two-time installation method is adopted, the ship manufacturing cycle is shortened, installation accuracy of the thruster is ensured, the use requirement of the thruster is met, and ship building quality is improved.

Description

technical field [0001] The invention relates to a method for installing a retractable full-rotation auxiliary propeller. Background technique [0002] The retractable full-turn auxiliary propeller, also known as the retractable rudder propeller, is a large-scale drive equipment used on marine engineering ships (such as twelve-cable geophysical exploration ships), and is arranged in the bow section. In order to improve the propulsion performance of marine engineering ships, this type of auxiliary propeller is widely used. Its main function is to drive the ship to a safe area when the ship is in an emergency situation, or to provide auxiliary propulsion power when the power of the main propeller is insufficient and the geophysical cable may be entangled. The retractable rudder propeller can be retracted when the ship is sailing and the speed does not exceed 5 knots, and the annual operation limit is 3000 hours. [0003] During the construction of the 12-cable geophysical exp...
