Description

Technical Field

[0001] The present invention belongs to the technical field of ships, and particularly relates to a height measurement tooling for limited space and its usage method. Background Technique

[0002] During shipbuilding, it is difficult to measure the gaps at some positions due to limited space. For example, when installing shock isolators for the main engine, the material of this equipment is rubber, which will slowly deform to a stable state under pressure. After the main engine is installed, the deformation of the shock isolator needs to be measured once or twice a day. After it stabilizes, the height position of the main engine can be completely determined, and then the shaft alignment can be carried out. The measurement efficiency of the deformation of the main engine shock isolator affects the shaft alignment. In the past, the height of the main engine shock isolator was usually measured using an internal micrometer. Although the measurement accuracy of the micrometer is sufficient, due to the complex environment and narrow space, the use of the micrometer is restricted, it is inconvenient for personnel to read the data, and the measurement is difficult.
