AI Technical Summary

Technical Problem

Existing hydraulic supports are prone to tilting or collapsing in inclined or uneven roadways, posing safety hazards. Furthermore, the protection of the top beam is easily loosened, affecting the safety of fully mechanized coal mining.

Method used

Design an adjustable hydraulic support, comprising a base, an adjustment component, and a support component. The base and protective plate are supported at multiple angles by rotating and extending the hydraulic rod. The hydraulic rod drives the auxiliary support plate and protective plate to adjust their angle and position within the tunnel to achieve stable support.

Benefits of technology

It effectively reduces the risk of hydraulic supports tipping over in inclined roadways, improves support stability, and enhances safety within the roadway.
