A new type of universal tire frame for ships

Abstract

A new general-purpose tire rack for ships, including two horizontal rails arranged at the front and rear, the two horizontal rails are parallel to each other, and a plurality of evenly distributed sliders are installed on the two horizontal rails, and the corresponding two horizontal rails are located on different horizontal rails. The two sliders are fixedly connected by a strip-shaped base. The length direction of the base is perpendicular to the horizontal rail. A long strip-shaped first horizontal plate is fixedly installed in the middle of the upper part of the base. The first horizontal plate is parallel to the base. The first horizontal plate The upper part is provided with a second horizontal plate, the second horizontal plate is the same size and parallel to the first horizontal plate, the first horizontal plate and the corresponding second horizontal plate are fixedly connected by a vertical plate, and the vertical plate is parallel to the length direction of the base . The invention replaces the traditional pillar round head with a plate-shaped electromagnetic indenter, changes point contact to surface contact, and evenly distributes the stress of the contact point, and uses the electromagnetic indenter suction to fix the segmented outer plate to solve the problem of segmental support in the tire frame support process. Deformation and slippage problems.

Description

Technical field [0001] The invention belongs to the technical field of shipbuilding, and specifically is a new type of general tire frame for ships. Background technique [0002] The tire frame is an indispensable technological equipment in the process of ship construction. During the assembly and welding of the segments, especially the segments with curved surfaces, the working surface of the tire frame fits the segment shape to support the segments. The frameless side provides a good working environment for segmented construction, which is beneficial to control welding deformation, improve construction conditions, improve construction accuracy, and speed up construction progress. The tire frames currently used in shipyards mainly include special tire frames and pillar tire frames, but the dedicated tire frames can only work once, which is time-consuming, laborious and wasteful of materials, and has been gradually eliminated; pillar tire frames have the following disadvantages: ...

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
