Method for ship anchoring system for failure diagnosing and additional material repairing

Abstract

The invention relates to a method for ship anchoring system for failure diagnosing and additional material repairing. The method is mainly applied to a three-dimensional scanning reverse engineering technology and an additional material manufacturing technology; coordinates of a relative zero point of the ship anchoring system, a three-dimensional measurement anchoring machine characteristic size and the coordinates of a key point, a three-dimensional measurement guide chain roller characteristic size and the coordinates of a key point, coordinates of an upper opening point and a lower opening point of a three-dimensional measurement anchoring chain cylinder and the inner diameter and outer diameter of the anchoring cylinder are selected, three-dimensional block scanning is conducted on point cloud data on the anchor mouth surface, anchor mouth profile point cloud data is processed, a computer virtual simulation anchor experiment is conducted, an anchor mouth is subjected to layered additional material manufacturing through rotary 3D printing equipment, and finally the ship anchor system is assembled to complete the error diagnosis and repair of the ship anchor system. The ship anchoring system has the advantages that in the design period, the failure of the ship anchoring system is accurately diagnosed and repaired, the defect in the building aspect of a current ship anchoring system is made up for, and the ship anchoring system has very significant importance whether in on civil ship building error control or warship building error control.

Description

technical field [0001] The invention belongs to the field of ship mooring system construction, and in particular relates to a method for fault diagnosis and additive repair of ship mooring system. Background technique [0002] It is difficult to control the construction accuracy of the anchor seat, anchor lip, anchor chain barrel and chain guide roller in the current ship mooring construction process. Especially for the anchor lip, once there is a construction error, it will seriously affect the bonding state of the anchor and the anchor lip. The anchor lip needs to be redone if necessary. At present, there are related ship precision construction methods: [0003] The patent for invention with the application number CN201010188201.0 is a segmented construction accuracy control method of a cylindrical ultra-deep sea drilling platform. It provides a method for solving the accuracy control of the main hull of a large drilling platform in current ocean engineering, and provide...
