Problems solved by technology
The gap between the stern tube and the cabin is only 40mm. The lifting personnel are struggling to work in the narrow space, and the work efficiency is low. It is difficult to ensure the smooth hoisting of the stern tube, and it is easy to damage the Babbitt alloy of the stern tube bearing and the oil pipe of the stern seal arranged on the inner wall. , the temperature probe protection tube, once damaged, it cannot be found in time, which will bring major quality hidden dangers to the later construction

Embodiment Construction
[0030] The present invention will be further clarified below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. Modifications of equivalent forms all fall within the scope defined by the appended claims of this application.
[0031] like Figure 1-10 As shown, a method for installing a stern tube of a ship includes the following steps:
[0032] S1, hoisting and transporting the stern tube lead-in device 1: the stern tube lead-in device is hoisted to the vicinity of the stern tube seat 2 by means of a hoisting device. The stern tube lead-in device includes a bottom plate 11, and hoisting rings 111 are installed on the front and rear sides of the bottom plate to facilitate lifting. Fourteen synchronous oil cylinders 12 are evenly installed on the surface. The telescopic end of the synchronous oil cylinder is f...

The invention discloses an installation method of a ship stern tube. The installation method of the ship stern tube comprises the following steps that S1, the stern tube guiding-in device is hoisted; s2, a stern tube leading-in device is positioned; s3, positioning the stern tube; s4, fixing the stern tube; s5, a stern tube is guided in; and S6, the stern tube leading-in device is withdrawn. The problems that in the prior art, the working efficiency is low, stable hoisting of the stern tube is difficult to guarantee, babbitt metal of a stern tube bearing, an oil tube of a stern seal arranged on the inner wall and a temperature probe protection tube are prone to being damaged, damage cannot be found in time, and great potential quality hazards are brought to later construction are solved.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to a method for installing a stern tube of a ship. Background technique [0002] In the process of ship construction, the installation of the integral stern tube is the first step in the installation of the entire shaft system. The overall stern tube is 5000mm long, Φ780mm in outer diameter, and weighs about 3T. The stern tube is hollow. When the stern tube is inserted from the rear to the front from the stern tube seat, the center of gravity is constantly changing. It is necessary to set up lifting lugs in the stern tube void to take advantage of it. Change the center of gravity. The gap between the stern tube and the cabin is only 40mm, which makes it difficult for the lifting personnel to work in the narrow space, and the work efficiency is low. It is difficult to ensure the smooth hoisting of the stern tube. , The temperature probe protection tube, once damaged, can not be found...
