AI Technical Summary

Technical Problem

During the construction of large facilities such as bridge piers and bases, workers in the prior art need to climb up and down on the outside of the formwork to install bolts, which poses safety risks and low installation efficiency, which is prone to problems such as insufficient tightening force and few bolts installation, resulting in the risk of collapse of the formwork.

Method used

A connecting member bolt installation device is designed, including a support frame, a load bearing mechanism and a mounting mechanism. Through the synchronous movement of the support frame, the bearing mechanism automatically pushes the bolts and nuts to the position on the template where they need to be installed. The installation mechanism uses a rotating head to connect the bolts and nuts to achieve automatic installation.

Benefits of technology

Through the automated installation device, manual operation is reduced, safety risks are reduced, construction efficiency is improved, and formwork collapse accidents caused by improper bolt installation are avoided.
