AI Technical Summary

Technical Problem

When adjusting the height of the support frame, the knob rotation is inconsistent, resulting in inconsistent height. The support screw is subject to great force and is easily damaged, affecting the adjustment adaptability and reducing practicality.

Method used

The combined structure of the arch frame, adjustment column and fixed column is adopted. By locking the beveled surface of the lower end surface, the arch frame is quickly adjusted and fixed, and the spring and elastic hose are used to quickly butt and lock the locking block and the locking groove to improve adjustment efficiency.

Benefits of technology

The rapid adjustment and fixation of the arch frame is achieved, the efficiency of installation and adjustment is improved, the risk of damage to the support screw is reduced, and the practicality of the tunnel support structure is improved.

Abstract

The utility model discloses a roadway supporting structure which comprises two arch-shaped frames, two symmetrical adjusting columns are movably connected to the lower end faces of the two arch-shaped frames, fixing columns are slidably connected to the ends, away from the arch-shaped frames, of the adjusting columns, movable grooves are formed in the fixing columns, and a plurality of evenly-distributed locking grooves are formed in the sides, away from the center positions, of the adjusting columns. A positioning frame is fixedly connected to the side, away from the center position, of the fixing column, a telescopic rod is slidably connected to the positioning frame, a locking block is fixedly connected to one end of the telescopic rod, and a diagonal plane is arranged on the lower end face of the locking block. Meanwhile, the adjusting column and the arch-shaped frame can be directly moved upwards in cooperation with the use of a diagonal plane of the locking lower end face, rapid adjustment of the arch-shaped frame can be achieved, a locking block and a locking groove can be rapidly locked in cooperation with a spring and an elastic hose, the supporting height of the arch-shaped frame can be rapidly adjusted and locked, and the installation and adjustment efficiency is improved.
