AI Technical Summary

Technical Problem

Existing protective panels for rock mining are inefficient to transport and assemble, making them difficult to install quickly and compromising the safety of workers.

Method used

A telescopic quick-assembly structure was designed, comprising components such as a mobile frame, protective baffle, outer sleeve, inner sleeve, elastic pin, and support buckle. It utilizes a motor-driven multi-stage telescopic screw and a pushing and unfolding mechanism, combined with a pull rope nose and a ground-inserting threaded spike, to achieve rapid assembly and stable fixation of the protective plate.

Benefits of technology

It enables rapid movement, assembly, and secure fixing of the protective panels, improving safety and efficiency in blasting operations and reducing the risk of the protective panels tipping over or shifting.
