Hopper plate joint butt joint structure and hopper applying butt joint structure

Abstract

The invention discloses an improved hopper plate joint butt joint structure. A separation angle plate arranged along a joint is welded and fixed at the butt joint position of two hopper plates, and a reinforcing part is arranged on the outside plate surface of each hopper plate. The separation angle plate is arranged on the outside of a hopper, and the reinforcing parts extend to the separation angle plate and welded and fixed. According to the structure, mechanical performances of the butt joint structure are comprehensively optimized, and the reinforcing parts on the surface of the hopper plates can form a similar sealed or half-sealed hopper hoop, so that the hopper overall strength and rigidity are greatly improved, and high torsion resistant and bearing capacities are provided. Particularly, when the optimized plate joint butt joint structure is used by the hopper plates in the condition of same bearing capacities, the hopper plate thickness can be reduced, or reinforcing part material models can be reduced, and accordingly, the hopper weight is reduced, materials are saved, and costs are reduced. The invention further provides the hopper applying the butt joint structure on the basis.

Description

technical field [0001] The invention relates to the field of bearing structure design, in particular to a butt joint structure of hopper plate plates and a hopper applying the butt joint structure. Background technique [0002] In metallurgical enterprises, containers such as hoppers or chutes are required for material transportation, storage and transshipment during production. Existing containers such as hoppers are mainly welded with steel plates, and steel plates with sufficient thickness are usually selected to meet the strength and rigidity requirements of the hopper. However, for a heavy-duty hopper or a large hopper, it will bear the torque generated by unbalanced support during actual work. In this case, it is not enough to rely solely on increasing the thickness of the steel plate; especially, increasing the thickness of the plate while It will inappropriately increase the self-weight, and in addition to increasing the cost of materials, its torsional strength can...

AI Technical Summary

Problems solved by technology

[0006] Combining the above two situations, it can be seen that the reinforcing plate of the hopper finally increases the strength and rigidity of each hopper plate itself, and does not form a hoop to the hopper as a whole, and cannot produce a tightening effect on the hopper

Therefore, the strength of the butt welds between the hopper plates has not been strengthened over the entire length, but instead increases the stress concentration of the hopper when it is torsionally deformed, making the welds more likely to crack
