A static balance detection device and a weight detection method of a marine propeller

Abstract

The invention provides a static balance detection device and a weight detection method of a marine propeller. The device includes an oil collecting pan, a suspension mechanism, a centering mechanism, a centering detection mechanism, an anti-shock and weighing mechanism, and a centering detection mechanism. The suspension mechanism includes a bearing column, a ball head, and a suspension ball seat. The centering detection mechanism includes a servo electric cylinder, a sensor base, a force sensor, and a V-shaped block. The anti-shock and weighing mechanism includes a hydraulic jack, a weighing Sensors, protective covers, barrier rings. The present invention designs a new centering detection mechanism, which keeps the propeller in a balanced state through the servo electric cylinder, collects the data on the sensor, and then calculates and decomposes the mass deviation of the blade through the host computer, which has the advantages of simple measurement operation, It has the characteristics of high intelligence and high reliability, and an anti-shock mechanism is designed at the same time, which greatly improves the safety of the device.

Description

technical field [0001] The invention belongs to the field of ships, and relates to a ship propeller static balance detection device and an overweight detection method, in particular to a propeller static balance detection device with impact resistance. Background technique [0002] The shipbuilding industry not only provides modern technical equipment for my country's naval construction, but also provides necessary material means for water transportation and ocean development in the national economy. As the core component of sailing power, the marine propeller is a key factor determining the overall performance of the ship. Propellers often produce vibration, noise, and reduced service life during operation. The reason is mainly caused by the unbalanced mass of the propeller blades. Therefore, propeller static balance has an important influence on ship performance. [0003] The Chinese patent with application number 201110057262.8 discloses a high-precision ship propeller ...

AI Technical Summary

Problems solved by technology

However, the problems with this device are: 1) This device has no safety protection structure. If a blade of the propeller to be detected is too heavy, a serious tilt will occur when the propeller is hoisted, and the device will be directly impacted and damaged.

2) This kind of device will cause the propeller to rotate during the suspension process, which will cause the outer cylinder and the inner hole of the propeller to shake, increasing the measurement error
