AI Technical Summary

Technical Problem

Existing curved square steel devices are difficult to hoist due to their large size and weight. They are also difficult to install and position in narrow mine bins and funnels, require high maintenance intensity, pose hoisting safety risks, and are prone to cracking due to stress concentration, which affects the service life and safety of the mine bins and funnels.

Method used

The curved square steel is divided into a female curved square steel and a male curved square steel, and the sections are installed by bolting to distribute the weight and stress, which facilitates positioning and hoisting. The left and right square steels are used to further enhance the connection stability.

Benefits of technology

It reduced the labor intensity of maintenance, extended the service life of the equipment, reduced safety hazards, and improved the stability and efficiency of production.

Abstract

The utility model relates to the technical field of arc-shaped square steel, in particular to a detachable easy-to-install novel wear-resistant arc-shaped square steel device which comprises female arc-shaped square steel and male arc-shaped square steel, the female arc-shaped square steel is matched with the male arc-shaped square steel, a first bolt through hole is formed in the female arc-shaped square steel, a third bolt through hole is formed in the female arc-shaped square steel, and the male arc-shaped square steel is matched with the first bolt through hole. The integral arc-shaped square steel is split into the female arc-shaped square steel and the male arc-shaped square steel, the matched shape of the female arc-shaped square steel and the male arc-shaped square steel can achieve the effect of facilitating positioning, the problem that the arc-shaped position is prone to cracking due to stress concentration is solved by splitting the square steel into segments, the weight is also dispersed, hoisting and mounting are facilitated, and the service life of the square steel is prolonged. Compared with the prior art, the arc-shaped square steel has the advantages that the maintenance intensity is greatly reduced, the service life of the arc-shaped square steel is prolonged, the base plate and the body of the ore bin and the funnel can be effectively prevented from being worn through, the potential safety hazard is reduced, the maintenance labor intensity is reduced, and the efficient and stable operation of production is improved.
