Abstract

A hydraulic positioning device for ship body segments comprises at least four hydraulic drive units. Each hydraulic drive unit comprises a base, a drive wheel, a hydraulic motor, a first hydraulic cylinder, a jacking hydraulic cylinder, a second hydraulic cylinder, a linkage mechanism, a first horizontal hydraulic cylinder, a second horizontal hydraulic cylinder, a slide plate, a driven wheel and a support. The drive wheel and the driven wheel are connected to the base through the linkage mechanism. The hydraulic motor is used for driving the drive wheel. The piston ends of the first horizontal hydraulic cylinder and the second horizontal hydraulic cylinder are connected to the same vertical shaft of the support through hinges. The bottom ends of the first horizontal hydraulic cylinder and the second horizontal hydraulic cylinder are connected to the base through hinges in an angled manner. The piston end of the jacking hydraulic cylinder is in contact connection with ship body segments. The bottom end of the jacking hydraulic cylinder is in contact with the base through the support and the slide plate. The first hydraulic cylinder and the second hydraulic cylinder are used for adjusting the linkage mechanism. The hydraulic positioning device is simple in structure and low in cost, manual positioning is avoided, and positioning efficiency and precision are increased greatly.

Description

technical field [0001] The invention relates to a hydraulic positioning device for a segmented hull and belongs to the technical field of segmented hull positioning. Background technique [0002] In the process of shipbuilding, the segmented hull is used for welding to complete the manufacture of the whole ship. During the welding process of each segmented hull, a certain relative pose relationship between the segmented hulls should be achieved to meet the requirements of the ship type and welding process, that is, the segmented hulls need to be positioned to control the pose of the segmented hulls . [0003] At present, in the shipbuilding process of many shipyards, the positioning of the segmented hull is carried out manually in the dock. This operation process is not only labor-intensive, but also has low efficiency and positioning accuracy. Contents of the invention [0004] The invention provides a hydraulic positioning device for segmented hulls to solve the proble...
