AI Technical Summary

⚠Technical Problem

Existing unit supports are difficult to adapt to various inclination angle requirements in the advance support of fully mechanized mining face roadways in underground coal mines, resulting in high labor intensity, low production efficiency and safety hazards.

⚗Method used

Design a unit support cross-hinged fixing device. By changing the height of the cross-hinged column cap assembly and replacing the pressure block, the inclination angle of the top beam can be adjusted to adapt to the inclination angle requirements of different roadways and working faces.

🎯Benefits of technology

It enables flexible adjustment of the top beam structure, reduces labor intensity, improves production efficiency and safety, reduces procurement and production costs, and adapts to various tunnel conditions.

Abstract

A unit support cross hinge fixing device, including roof beam and two groups of cross hinge column cap assemblies, two groups of cross hinge column cap assemblies are arranged between two main bars of roof beam and are arranged forward and backward along the direction of roof beam, by height change of two groups of cross hinge column cap assemblies, the adjustment of roof beam inclination is realized, so as to meet the inclination requirement of mine roadway and working face. When the inclination of roadway changes greatly, the advanced support does not need to be replaced, and the support measure is also reduced. The utility model not only greatly reduces the design and production cost of manufacturers, but also greatly reduces the production cost of coal mine and the labor intensity of workers, improves the work efficiency, reduces the safety hidden danger, and ensures the safe and efficient production of coal mine.
