AI Technical Summary

Technical Problem

Existing coal mine roadway support devices require on-site splicing of multiple components and fixing with a large number of bolts, resulting in slow installation speed, high physical exertion for workers, and low efficiency, making it difficult to meet the rapid support needs of complex underground environments.

Method used

The system employs a combination of connectors and fixing rods. The connectors allow for quick connection between the top plate and the vertical plate, while the fixing rods ensure a stable connection, reducing the use of bolts. The system also incorporates a lead screw mechanism and a limit mechanism for height adjustment and stable fixation.

Benefits of technology

It enables rapid installation of coal mine roadway support, reduces the number of bolts used, improves construction efficiency and stability, and meets the rapid support needs of complex underground environments.
