Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and particularly to an automatic measuring device for the bearing reaction force of a shafting system, specifically an automatic measuring device for the bearing reaction force used in the installation of a ship shafting system. In particular, it relates to a technical solution for quickly measuring and adjusting the bearing reaction force of a shafting system through high-precision sensing technology and intelligent algorithms. Background Art

[0002] The shipping industry undertakes 80% of the global cargo transportation, promotes the formation of the global supply chain, and drives economic globalization. With the continuous advancement of world integration and the continuous improvement of world trade, the shipping industry has developed rapidly. The shafting system provides power for the ship's movement and is an important part of the ship. Its installation quality affects various aspects such as the ship's service life, navigation safety, and economic benefits. Therefore, developing a highly automated and high-precision shafting installation technical solution is of great significance for improving installation accuracy, reducing labor costs, and increasing production efficiency.

[0003] In the existing technology, for the measurement of the bearing reaction force of each bearing of the traditional shafting system of a ship, a dial indicator 5 is installed above the force measurement point, and a force measurement oil cylinder 6 (equipped with a manual hydraulic pump with a pressure gauge 9) is placed below. When measuring the force, the dial indicator 5 is reset to zero, and the manual hydraulic pump is manually controlled to gradually increase the pressure of the force measurement oil cylinder 6. The forces during the lifting and lowering of the hydraulic jack (jack force = measured oil pressure × area of the oil cylinder 6) and the values of the dial indicator 5 are recorded to depict the force measurement curve. After calculating the force on the force measurement oil cylinder 6 and multiplying it by the jacking coefficient, the actual load of the bearing can be measured, as shown in Figure 1 .
