Description

A three-dimensional vertical lifting storage mechanism for straight steel bars

technical field

The utility model relates to the field of steel bar storage equipment, in particular to a three-dimensional vertical lifting type storage mechanism for straight steel bars.

Background technique

With the rapid development of industrial production, the use of straight steel bars is also increasing. Due to the characteristics of large diameter, long length, and heavy weight, straight steel bars require corresponding storage equipment for storage. At present, the storage equipment for straight steel bars is divided into flat storage bins and rotary storage bins. Among them, the flat storage bins are arranged in sequence with multiple long storage tanks, which can realize the simultaneous storage of multiple bundles of straight steel bars. However, the tiled grain storage silo has problems such as large floor area, simple structure, low degree of automation, and inability to work at fixed points when extracting or replacing raw materials. The rotary storage bin can realize the three-dimensional storage of straight steel bars and can work at a fixed point, but because it is a rotary storage bin, it needs to provide enough power for the overall rotation of the steel bars. When the storage positions of the steel bars are uneven, then When performing rotating work, it needs to provide a large power, which consumes a lot of energy, and because it is a rotating structure, it means that all the steel bars are moving. Because the weight of the steel bars is relatively large, its safety performance is poor.
