[0002] The stern tube of a large bulk carrier is usually designed with a single bearing. In the construction stage of installing the stern shaft to the stern tube, the conventional method is to use a manual chain hoist to lift it slowly. Due to the heavy weight of the stern shaft, this method is not only time-consuming, It is laborious, and the stern shaft is easy to move inside the stern tube during the hoist pulling process, which is very easy to damage the Babbitt alloy of the stern tube bearing, the oil pipe of the stern seal arranged on the inner wall, and the temperature probe protection tube. Once damaged, it cannot be found in time. Late construction brings major quality risks

Embodiment Construction
[0045]The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0046] Such as Figures 1 to 3 Shown is an embodiment of a ship stern shaft installation method of the present invention, comprising the following steps:
[0047] (1) The setting of the roller frame: the roller frame 22 is set at the hoisting entrance of the stern shaft 5 close to the stern tube assembly 24; a pair of rollers;
[0048] (2) Setting of the flexible guide device: the rear end of the roller frame 22 is provided with a flexible guide device 25 for the stern shaft 5 to advance axially during traction; Live four elastic pneumatic tires 4 of the stern shaft 5;
[0049] (3) Pre-adjust the roller frame and flexible guide device: adjust the positio...

The invention relates to the technical field of marine equipment installation, and discloses a method for installing a stern shaft of a ship, comprising the following steps: (1) setting a roller frame; (2) setting a flexible guide device; (3) presetting the roller frame and the flexible guide device; 4) hoisting a stern shaft; (5) confirming the stern shaft center position; (6) towing the stern shaft into the stern tube inner hole; (7) loosening the roller frame and the flexible guide. The method can ensure that the ship stern shaft accurately and steadily enters the stern tube when the ship stern shaft is hoisted, and can prevent the stern tube from being damaged by the movement or shaking of the stern shaft when the ship stern shaft is hoisted, thereby realizing the installation of the stern shaft with high quality and improving the installation efficiency of the stern shaft.
Description
technical field [0001] The invention relates to the technical field of ship equipment installation, in particular to a method for installing a ship stern shaft. Background technique [0002] The stern tube of a large bulk carrier is usually designed with a single bearing.
