AI Technical Summary

Technical Problem

The installation process of traditional bolt-fixed rolling fenders is cumbersome and poses risks of working at height. Furthermore, disassembling and reassembling internal components can easily lead to equipment malfunction.

Method used

The design employs a bolt hole without threads, which involves pre-drilling aligned unthreaded holes on the hull and rolling fenders, and then using a combination of wire and nuts to install and tighten the bolts inside the hull, thus avoiding high-altitude operations.

Benefits of technology

It enables rapid installation without disassembling internal components, reduces the risks of working at heights, improves installation efficiency, and reduces operational problems after equipment reassembly.

Abstract

The application discloses a quick installation method of a bolted rolling fender, and belongs to the technical field of ship and ocean engineering construction. The rolling fender comprises a shell, a tire and a roller. The purpose of the method is to quickly install the rolling fender on a ship body by using a bolt assembly mode. The installation steps are as follows: step one, a bolt hole is formed at an installation position of the ship body; step two, the whole rolling fender is hoisted to the installation position of the ship body; and step three, bolts are installed and fastened. The method does not need to disassemble precise components such as the tire and the roller in the rolling fender, and the quick fixing is realized by using a specific bolt assembly mode, so that the problems of high-altitude risk, complicated process and equipment reinstallation in the traditional installation are solved.
