Problems solved by technology

Traditional retractable azimuth propellers are generally installed in docks, but for propellers with a diameter greater than 3 meters in the underwater part, if they are to be installed normally, the outer plate of the ship’s bottom to the bottom of the dock must be greater than 3.3 meters, and the height of the dock pier of the shipyard is generally It is 1.8 meters, which cannot meet the installation of this thruster

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] A method for installing a telescopic azimuth thruster of the present invention comprises the following steps:

[0025] Such as figure 1 As shown, the bracket tooling 2 and the cover plate tooling 3 are designed in the pit 1 of the general group site, and then the underwater part 4 of the telescopic azimuth propeller is placed on the bracket tooling 2; the cover plate tooling 3 is placed on Above the underwater part 4 of the retractable azimuth propeller; then place the thrust beam 18 and the underwater support plate 5 on the cover plate tooling 3; then position the bottom section 6 above the pit, and fix it with a support 7, At the same time, the flatness processing of the base plane of the telescopic azimuth thruster is completed;

[0026] Such as figure 2 As shown, install the installation base 9, the underwater conduit 10 and the ...

Abstract

The invention discloses a mounting method for a retractable full-revolving propulsor. The mounting method for the retractable full-revolving propulsor comprises the following steps of placing an underwater portion of the retractable full-revolving propulsor on a bracket tool of a pit; designing a shield plate tool for the underwater portion; protecting the underwater portion of the retractable full-revolving propulsor by using the shield plate tool and using the shield plate tool as a working platform provided with the retractable full-revolving propulsor; performing planeness machining on a plane of a base of the retractable full-revolving propulsor in a subsection of a hull bottom in an open operation environment which facilitates machining of the plane of the base after subsection positioning is finished; mounting other components of the propulsor after assemble welding on a hull structure of a block with the retractable full-revolving propulsor is finished; and performing a total-travel retracting test on the retractable full-revolving propulsor in a main assembling field.

Description

technical field [0001] The invention relates to a method for installing a retractable full-turn thruster. Background technique [0002] Due to the needs of dynamic positioning, marine engineering ships are equipped with retractable azimuth propellers at the bow. Traditional retractable azimuth propellers are generally installed in docks, but for propellers with a diameter greater than 3 meters in the underwater part, if they are to be installed normally, the outer plate of the ship’s bottom to the bottom of the dock must be greater than 3.3 meters, and the height of the dock pier of the shipyard is generally It is 1.8 meters, which cannot satisfy the installation of this propeller. Contents of the invention [0003] The object of the present invention is to provide an installation method of a telescopic full-rotation telescopic pusher that can be installed in the pit of the general assembly site. [0004] The purpose of the present invention is achieved through the follo...
