AI Technical Summary

Technical Problem

Existing hydraulic climbing formwork devices require manual pinning to secure them when they reach the designated position, resulting in high difficulty and safety risks for high-altitude operations.

Method used

Design a pin insertion mechanism for hydraulic climbing formwork used in high-pier bridges. The mechanism utilizes deflection blocks and limiting components to achieve automated fixing of the platform connecting plate. The weight of the platform connecting plate applies pressure to deflect and reset the deflection blocks, thus locking them in place and avoiding manual pin insertion.

Benefits of technology

The system automates the fixing of the platform connection plate, reducing the difficulty and safety risks of high-altitude operations and improving the safety and efficiency of operations.
