Marine propeller static balance detection device and method

Abstract

The invention discloses a static balance detection device and a static balance detection method suitable for a large marine propeller. The static balance detection device comprises a suspended weighting adjustment mechanism, wherein a coaxial centering detection and positioning platform is arranged just above the suspended weighting adjustment mechanism, and a centering adjustment mechanism is arranged on the periphery of the centering detection and positioning platform; the upper end of the centering detection and positioning platform is provided with a vision imaging and laser center searching device, a rotary platform is arranged below the vision imaging and laser center searching device, a positioning and supporting flange plate is coaxially and fixedly connected just below the rotary platform, a hemispheric bearing is fixedly connected just below the positioning and supporting flange plate, two horizontal sensors are symmetrically arranged on the edge of the lower surface of the upper part of the hemispheric bearing, a hemispheric cavity is formed in the center of an upper-segment cylinder of a platform hydraulic floating base of the suspended weighting adjustment mechanism, and the hemispheric cavity is matched with the hemispheric bearing. According to the static balance detection device and the static balance detection method, the coarse positioning precision in the hoisting process of the propeller is improved by adopting the vision imaging technology, the centering is realized by means of a jacking and stretching mechanism, propellers with different radii can be detected, and the universality and detection precision are improved.

Description

technical field [0001] The invention relates to a static balance detection technology, which is especially suitable for the static balance detection of large marine propellers. Background technique [0002] The size of propellers used in large ships is getting bigger and bigger, and the speed is getting higher and higher, which puts forward new requirements for the balance detection of large ship propellers. The static balance detection of large marine propellers is actually the detection of tiny unbalanced moments of the propellers. It is a difficult technology to measure the tiny unbalanced moment of the giant rotor with a small-scale precision measuring system. Due to the large size and mass of the large propeller, it brings great difficulties to the balance check. [0003] At present, the static balance test of the propeller is mainly the balance hanging method. The balance hanging method is to use a rigid support to assemble the propeller, the mandrel and the rolling ...
