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.

Embodiment Construction

[0042] The present invention realizes the turnover function of the ship section without lifting lugs and without a crane, and provides a turnover system and implementation method of the ship section. The present invention will be further described below in conjunction with the accompanying drawings.

[0043] Such as figure 1 with 2 , combined with Image 6 with 7 The turnover system of hull segments in the ship building process of the present invention is shown, including turnover equipment and mobile lift car equipment. Among them, such as figure 1 with 2 As shown, the turning device includes a turntable 11 whose two sides are respectively fixed on the turning circle 21 for turning over; the turntable 11 includes an electromagnet adsorption component and a plane that is attached to the hull section. Such as image 3 As shown, driven round pins 22 are arranged at intervals on the outer circumference of each said turning circle 21, and cooperate with the outer drive gear ...

Abstract

The invention discloses hull block turning equipment provided with clamping and protecting mechanisms during ship construction. The hull block 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). Wide slots are formed at the edge, contacting with the hull block, of the rotary table (11). Movable clamping components are arranged in the wide slots. Each movable clamping component comprises a track frame component which is perpendicular to the plane of the rotary platform and moves outwards parallelly to the plane of the rotary platform. Clamping claws are arranged in the track frame components. Each clamping claw is provided with a hydraulic component for moving the claws in two directions. By the hull block turning equipment, construction cost 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...
