Tail shaft pipe adjusting tool and using method

Abstract

The invention relates to a tail shaft pipe adjusting tool which comprises four sets of 7-shaped codes welded to a front tail column and a rear tail column, the 7-shaped codes are arranged in the radial direction of a tail shaft pipe, two through holes with internal threads are formed in each 7-shaped code, and an adjusting bolt arranged in the axial direction of the tail shaft pipe is installed ineach through hole. The adjusting bolt is arranged in the radial direction of the tail shaft pipe and can adjust the position of the tail shaft pipe through rotation. Compared with the prior art, thetail shaft pipe adjusting tool is simple in structure and convenient to use. The invention further provides a using method of the tail shaft pipe adjusting tool, the process is optimized, the operation steps are reduced, the workload is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a stern tube adjusting tool and a using method. Background technique [0002] The stern tube is one of the important devices of the ship. It is used to support the propeller shaft and keep the hull watertight to prevent a large amount of outboard water from leaking into the ship. It also prevents lubricating oil from leaking out and polluting seawater. Since the stern tube needs to support the propeller shaft, the installation position of the stern tube will directly affect the arrangement of the center line of the shaft system, which has a great impact on the entire axis. In addition, it involves the normal use of the ship and affects the safety of shipping. The installation of the shaft tube is a very important link. [0003] Such as figure 1 As shown, the existing stern tube adjustment tooling includes a pressure plate 100 and a bolt 200. When in use, a plurality of bol...

AI Technical Summary

Problems solved by technology

[0005] 1. It needs to weld and install the pressure plate on the end surface of the rear stern post and the rear stern tube, and at the same time drill and tap the front and rear stern post structures, which requires a lot of work and takes a long time;

[0006] 2. After the epoxy casting stern tube is installed, it is not only necessary to arrange workers to cut off the pressure plate and the bolts protruding from the tail post structure, but also to use epoxy sealing plates to seal the bolt holes. The steps are cumbersome and inefficient;

[0007] 3. The sealing requirements of the bolt holes are extremely high, and special welding methods and requirements must be strictly followed for hot work. The technical requirements for the construction personnel are very high, and there is a risk of epoxy fracture of the stern tube, so it is difficult to implement Big
