Description

A kind of auxiliary installation equipment for ship stern tube

Technical field

The present invention relates to the field of ship installation auxiliary, and in particular to a ship stern tube auxiliary installation equipment.

Background technique

A ship is a vehicle that can sail or be parked in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. The important equipment installed at the bottom end of the ship is the stern shaft. One end of the stern shaft It is connected to the propeller, and the other end is connected to the gearbox or coupling and then to the engine. The engine drives the propeller to rotate through the stern shaft to drive the ship to sail. The more important structure connected to the stern shaft is the stern tube, which is the auxiliary stern tube. It is a necessary structure for the stable operation of the shaft. Most of the existing auxiliary devices for stern tube installation do not have the functions of moving, adjusting and fixing during use, making it inconvenient for users to use.

Chinese patent CN114228941B discloses an improved auxiliary device for ship stern tube installation. The stern tube is placed by placing a plate, and the stern tube is axially fixed in the X direction by two arc plates, and by two moving blocks. The stern shaft tube is axially fixed in the Y direction. The angle adjustment device is used to make the placement plate drive the fixed stern shaft tube for angle adjustment. The height adjustment assembly is used to make the placement plate drive the fixed stern shaft tube for height adjustment. However, this When using this solution, you need to manually control the arc plate to move first so that the stern tube can pass between the arc plate and the placement plate. This process needs to be repeated twice, and then after the stern tube passes through the first arc. After shaping the plate, the position of the first arc-shaped plate must be fixed so that it cannot currently contact the stern tube. Otherwise, the first arc-shaped plate will block the movement of the stern tube, thus making the loading of the stern tube more cumbersome and inconvenient. , at the same time, when the stern tube passes through the first arc plate and continues to move, you need to pay attention to the distance between the worker's hand placed on the first arc plate and the stern tube. If the distance is small, there will be an arc The plate cooperates with the stern tube to cause friction and damage to the workers' hands.
