Lift roller based hull block turning equipment during ship construction

Abstract

The invention discloses lift roller based hull block turning equipment during ship construction. The turning equipment comprises a rotary table (11). Two sides of the rotary table (11) are fixed on rotary rings (21) used for overturning respectively. The rotary table (11) comprises an electromagnet adsorption component and a plane attached to a hull block. Each rotary ring (21) rotates together with an outer side driving gear (33). Grooves are formed in the plane, attracted to the hull block, of the rotary table (11) at intervals. Lift roller components (12) are arranged in the grooves. Each lift roller component (12) comprises a track (123) perpendicular to the plane of the rotary table (11). Roller carriers (124) with rollers (121) are arranged in the tracks (123). Lift roller hydraulic oil cylinder components (122) are connected to the lower sides of the roller carriers (124). Rotary shafts of the rollers (121) are connected with roller driving motor components. By the turning equipment, construction cost of the hull block is greatly reduced, and construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ship building, and more specifically, relates to construction equipment and a turning method for ship hull sections. Background technique [0002] The ship construction of prior art, especially large-scale ship, mostly adopts the segmental construction, then closes up the mode of general assembly. In the construction process of each ship segment, the construction in both the upper and lower directions is bound to be required. Generally speaking, downward construction is relatively easy, while upward construction is relatively difficult for ship construction with many welding processes, and upward welding is required. Moreover, in the process of building sections of ships, the efficiency of face-up welding is low, and the welding quality is difficult to guarantee. Therefore, in order to avoid the problem of face-up welding, it is necessary to turn over the parallel body segment by 180 degrees, and the fa...

Problems solved by technology

However, the construction and maintenance costs of large-scale cranes are relatively high. At the same time, when the crane is used to turn over the ship in sections, the section will have a downward acceleration when turning over the critical point, which will be dangerous to the crane and the entire turning process.
