Device for correcting butt joint 'II-shaped' misalignment of flat-bulb steel

Abstract

The invention discloses a device for correcting butt joint 'II-shaped' misalignment of flat-bulb steel. The device comprises two main boards, model holes are disposed on the main board, the shape of each model hole corresponds to that of the cross section of the flat-bulb steel, the main boards are connected with each other by a nut plate, a nut hole is disposed on the nut plate, a screw is connected onto the nut hole in a threaded manner, the top end of the screw is opposite to a position nearby the middle of the upper middle portion of flat-bulb steel in the height direction of the flat-bulb steel, and a sharp iron inserting hole is arranged on one side, which is opposite to the nut plate, of each main board. The device is used for correcting the misalignment of the flat-bulb steel, butt joint 'II-shaped' alignment correction assembly efficiency of the flat-bulb steel can be improved, the assembly quality is enhanced, welding stacking plates are omitted, stacking plate scars are prevented, coating layers are prevented from being damaged, the device is simple in manufacture, convenient in carrying and quick in assembly and disassembly, labor and material wastage can be effectively reduced, work efficiency is improved, the butt joint 'II-shaped' misalignment of the flat-bulb steel can be corrected, and accordingly the device can be widely used for ship making fields and is safe and reliable.

Description

technical field [0001] The invention relates to an auxiliary device for correcting "Type II" dislocation of spherical flat steel butt joints in the ship production process, and belongs to the field of ship assembly. Background technique [0002] With the continuous development of the shipbuilding industry and the overcapacity of ships, the competition among the industries is becoming increasingly fierce. Improving production efficiency, reducing production costs, and reducing and avoiding repeated construction volumes have become urgent problems that need to be solved urgently. In the process of ship production and construction, due to factors such as marking deviation, installation alignment deviation, design size deviation or loading positioning deviation, the bulb flat steel butt joint at the closing mouth of the segment forms a "Type II" dislocation when closing. In the past, the method of correcting the misalignment was to weld the code plate and use jacks or gourds to ...

AI Technical Summary

Problems solved by technology

In the past, the method of correcting the misalignment was to weld the code plate and use jacks or gourds to correct it. This required a series of workloads such as welding the code plate, removing the code plate, grinding, destroying the paint, and repainting, and the efficiency was low. , seriously affecting production efficiency and increasing costs, greatly reducing the competitiveness of enterprises
