PRECISE POSITIONING SYSTEM FOR HYDRAULIC IMPACT HAMMER

WIPO Patent Application WO/2024/037120

A1

The present invention relates to a precise positioning system for a hydraulic impact hammer, the precise positioning system comprising a first positioning device mounted on a dredging ship, a second positioning device mounted on a frame, a third positioning device for collecting position information of a hanging point for the frame, a first sensing device mounted on the frame, and a second sensing device mounted on the frame, wherein a positioning calculation device collects data of each of the first positioning device, the second positioning device, the third positioning device, the first sensing device and the second sensing device and calculates position information of a hydraulic impact hammer. On this basis, the influence of hanger luffing and ship tilting on the lowering depth of a hydraulic impact hammer can be ignored, thereby ensuring the positioning precision and positioning stability of the hydraulic impact hammer.
