Novel universal moulding bed for ship

Abstract

The invention discloses a novel universal moulding bed for a ship. The novel universal moulding bed comprises two cross rails arranged back and forth; the two cross rails are parallel to each other; each of the two cross rails is matched and provided with a plurality of uniformly distributed slide blocks; the two corresponding slide blocks located on the different cross rails are fixedly connectedby a strip-shaped base; the length direction of the base is vertical to the cross rails; a strip-shaped first transverse plate is arranged in the middle of the upper part of the base; the first transverse plate is parallel to the base; the upper part of the first transverse plate is provided with a second transverse plate; the second transverse plate is same as the first transverse plate in sizeand is parallel to the first transverse plate; the first transverse plate is fixedly connected with the corresponding second transverse plate by a vertical plate; and the vertical plate is parallel tothe length direction of the base. According to the novel universal moulding bed, a traditional supporting column fillister head is replaced with a platy electromagnetic pressure head, and point contact is changed into surface contact, so that the stress of a contact point is halved; and a sectional outer plate is fixed by virtue of the suction of the electromagnetic pressure head, so that the problems of sectional deformation and slippage in a moulding bed supporting process are solved.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a new general-purpose tire frame for ships. Background technique [0002] The tire frame is an indispensable process equipment in the shipbuilding process. During the assembly and welding of the segments, especially the segments with curved surfaces, the working surface of the tire frame fits the shape of the segment and supports the segment. The skeleton-free side makes segmental construction have a good working environment, which is conducive to controlling welding deformation, improving construction conditions, improving construction accuracy, and speeding up construction progress. The tire frames currently used in the shipyard mainly include special tire frames and pillar type tire frames, but the special tire frames can only be used once, which is time-consuming, laborious, and material waste, and have been gradually eliminated; the pillar type tire frames h...

AI Technical Summary

Problems solved by technology

The tire frames currently used in the shipyard mainly include special tire frames and pillar type tire frames, but the special tire frames can only be used once, which is time-consuming, laborious, and material waste, and have been gradually eliminated; the pillar type tire frames have the following disadvantages: ① pillars The head is usually a round head, which is not conducive to segmental fixation, especially for segments with large curvature, which may easily cause segmental slippage; Thin-plate steel structure; ③ The pillars are single and independent, and can only be fixed to support the sections. After the completion of the sections, they cannot be moved, and must be operated at high altitude with the help of hoisting equipment; ④ The height of the pillars is adjusted by the bolt, and the minimum adjustment process is small, and additional manual measurement and adjustment are required. poor precision
