Embodiment Construction

[0030] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:

[0031] The invention discloses a method for installing a super-long tail shaft with a shaft and a generator, which is not only suitable for the installation process of the super-long tail shaft, but also suitable for the removal of the super-long tail shaft and the docking inspection process of ships.

[0032] Take the DF15500 ro-ro ship as an example to complete the shafting installation of the main engine. The ro-ro ship is a stern type, with direct drive of two shafts. The main engine is B&W8S50ME-C9.5 low-speed two-stroke marine diesel engine produced by Hudong. The SMCR: 11800KW x117r / min, CSR: 10300KW x117r / min are irreversible diesel engines, two sets per ship. The propulsion propeller is MAN Alpha adjustable propeller (with tailwind propeller function). The shaft generator is a shaft-holding type shaft ge...

Abstract

The invention discloses a method for installing an ultra-long tail shaft with a shaft and a generator, which includes the following steps: S1, selecting key points that the tail shaft needs to support during the installation process of the tail shaft; S2, setting screw holes and sliding supports at the key points device; S3, check whether the bearing load is within the safe range: if it is within the safe range, perform S4, if not within the safe range, add key points and sliding support devices and return to step S3; S4, install the tail shaft; S5, After the shaft is in place, remove the sliding support and screw in the watertight cover at the screw hole. The invention divides the super long shaft system by splitting the shaft system, adopts segment positioning and multi-point jacking, so it has practical operability, can realize the installation of super long tail shaft safely and conveniently, and is also suitable for super long tail shaft Shaft removal process.

Description

technical field [0001] The invention belongs to the field of installation technology of ship equipment, and in particular relates to a new technology and method for installing super-long shafting. Background technique [0002] At present, in order to meet the requirements of loading and speed of some large ro-ro ships, the line shape of the tail is relatively large, and in order to improve the propulsion efficiency of the propeller, the propeller has to be placed as far back as possible. Therefore, the length of the stern shaft of this type of ship will be very long (over 20 meters) and extend out of the hull plate, and at the same time, a permanent hanger for the shafting system needs to be provided externally to ensure the rigidity of the bearing position. [0003] For the installation of the tail shaft, due to its own weight, the front section of the shaft will naturally sag, which will cause the front end of the tail shaft to contact the bearing or the wall of the tail p...
