Description

Stacking structure of hot-rolled hat-shaped steel and stacking and bundling method
Technical Field
The invention belongs to the technical field of hot-rolled hat-shaped steel production, and particularly relates to a stacking structure of hot-rolled hat-shaped steel and stacking and bundling methods.
Background
Because the section shape of the hot-rolled hat-shaped steel is special, how to pile up the hat-shaped steel before bundling is a big problem in the current production field of the hot-rolled hat-shaped steel. The stacking method is closely related to the tightness degree of the bundled stack, the stability of the bundled stack in the transportation process and the quality guarantee of products. When the stacking method is unreasonable, the bundled stack is loosened and easily scattered in the transportation process, so that the surface of a product is scratched, even the product is subjected to plastic deformation, and the section size is not proper; similarly, the unreasonable bundling method still causes the above situation. Therefore, it is necessary to design a stacking and bundling method suitable for hot-rolled hat-shaped steel according to the particularity of the hot-rolled hat-shaped steel.
There are numerous patents published on the palletizing and bundling method, such as patent application No. CN201911357802.7, which discloses a pipe rapid palletizing device and a palletizing method, including a transport frame, a pipe supporting mechanism, the pipe supporting mechanism includes a rotating component and a supporting piece for receiving the pipe, the rotating component is connected with the supporting piece; the stacking mechanism comprises a pipe clamping assembly and a lifting assembly; the pipe clamping assembly comprises a driving assembly and two symmetrically arranged abutting assemblies, and the driving assembly is connected with the abutting assemblies; the lifting component is connected with the pipe clamping component. The cut pipes are collected on the support piece through the pipe supporting component, the pipe clamping component clamps the pipes on the support piece, the pipes are placed on the pipe transfer trolley under the action of the lifting mechanism, the mechanical pipe supporting component, the pipe clamping component and the lifting component are used for achieving mechanical stacking of the pipes, manual operation in the prior art is replaced, labor force output is reduced, and stacking and loading efficiency is improved. Because the pipe has a round outline, the stacking and bundling processes are relatively simple, and the cross section of the hot-rolled hat-shaped steel has a special shape, the stable and reasonable bundling can not be realized by adopting the method.
Also, for example, patent application No. CN201910537899.3 discloses a section steel stacking apparatus and a section steel stacking method. The section steel stacking equipment comprises a conveyor for conveying section steel rows, a first steel dividing device and a second steel dividing device, wherein the first steel dividing device is sequentially arranged along the conveying direction of the conveyor and is used for separating the section steel rows on the conveyor to obtain the section steel rows with the required number of the section steels; the translation stacking machine is arranged above the conveyor and used for carrying and conveying the spaced profile steel rows to a required stacking station; and the overturning stacker crane is arranged at the output end of the conveyor and is used for overturning the spaced profile steel row to a required stacking station. According to the section steel stacking equipment, the steel separation, layering and stacking of various types of section steel can be met. The patent relates to a method for arranging and stacking section steel, and does not relate to a specific stacking and bundling method for each steel branch of cap-shaped section steel.
