AI Technical Summary

Technical Problem

Existing underground cage detection devices pose significant safety hazards when the fall arrestor is damaged, and cannot effectively guarantee the safety of the cage and the personnel inside.

Method used

An acceleration sensor is configured to detect the cage speed. Combined with a support plate, buffer spring, collision sensor, and ring-shaped airbag assembly, it provides additional cushioning protection in the event of fall arrestor failure. A laser rangefinder sensor monitors the distance in real time and triggers the airbag inflation.

Benefits of technology

In the event of a fall arrestor failure, the cushioning effect of the annular safety airbag assembly further enhances the safety and reliability of the cage operation, ensuring personnel safety.
