AI Technical Summary

Technical Problem

Existing technology has failed to effectively limit the axial displacement of the hot blast stove crossbeam, resulting in uneven grate plate installation and uneven stress, which affects the structural stability of the grate and may even lead to the collapse of the hot blast stove wall, shortening its service life.

Method used

By setting receiving grooves and recesses on the support column to limit the width and length of the crossbeam, and combining the connection between the positioning pin and the support column, the crossbeam can be quickly positioned and stably installed, preventing the crossbeam from tilting.

Benefits of technology

This improves the assembly efficiency and stability of the crossbeams, prevents damage to the grate, and extends the service life of the hot blast stove.

Abstract

The utility model provides a grate cross beam displacement prevention structure which comprises a supporting column, vertical plates extending upwards are arranged on the two sides of the upper end of the supporting column, a boss protruding upwards is arranged in the center of the surface of the supporting column between the two vertical plates, and containing grooves used for containing a cross beam are formed in the positions, located between the vertical plates, of the two sides of the boss. The cross beam is reasonable in design structure, on one hand, the cross beam can be limited in the width direction by forming the containing groove, and the cross beam can be limited in the length direction by forming the groove in the cross beam, so that in the assembling process of the cross beam and the supporting column, the positioning effect can be rapidly achieved, and the assembling efficiency is improved; the purpose of preventing the cross beam from moving in the horizontal direction can also be achieved; and on the other hand, the cross beam and the supporting columns can be further connected through the positioning pins, the problem of tilting caused by uneven stress on the upper portion of the cross beam can be solved, the installation stability of the cross beam is improved, and then the grate is prevented from being damaged.
