Description

Ship stern shaft color-changing early warning type installation method

Technical Field

The invention relates to the technical field of ships, in particular to a ship stern shaft discoloration early warning type installation method.

Background

Ships, a collective term for various ships. A ship is a vehicle which can be sailed or moored in a water area for transportation or operation, and has different technical performances, equipment and structural types according to different use requirements. A ship is a man-made vehicle that operates primarily in geographic water. In addition, a civil ship is generally called a ship, a military ship is called a ship, and a small-sized ship is called a boat or a boat, which is collectively called a ship or a boat. The interior mainly comprises a containment space, a support structure and a drainage structure, with a propulsion system using an external or self-contained energy source. The appearance is generally favorable for overcoming the streamline envelope of the fluid resistance, the materials are continuously updated along with the technological progress, the early materials are natural materials such as wood, bamboo, hemp and the like, and the modern materials are mostly steel, aluminum, glass fiber, acrylic and various composite materials.

The stern tube of a large bulk cargo ship is usually designed by a single bearing, and in the construction stage of installing the stern shaft into the stern tube, the conventional method is to slowly carry out hoisting by adopting a manual hoist pulling method, because the dead weight of the stern shaft is heavy, the method is time-consuming and labor-consuming, and the stern shaft is easy to shift in the stern tube in the pulling process of the hoist, so that babbitt metal of the stern tube bearing, an oil tube of a stern seal arranged on the inner wall and a temperature probe protection tube are extremely easy to damage, once the damage cannot be found in time, great quality hidden dangers are brought to later construction, and China with application number of 201811230644.4 discloses a ship stern shaft installation method, and the stern shaft is assisted to hoist by arranging a stern roller frame and a flexible guide device.

Although above-mentioned scheme can guide the stern axle to hoist, is difficult for appearing great drunkenness, but the difficult stable control of calabash lifting rope in hoist and mount in-process, consequently have the guidance and can also avoid appearing the skew, lead to the stern axle even can get into the stern pipe when hoist and mount, nevertheless wearing and tearing are comparatively serious and can't in time discover at hoist and mount in-process, and damage and trouble appear easily in the stern axle in the later stage working process, very big shortening working life.
