Casting blank self-stabilizing lifting device

Abstract

The invention relates to the technical field of casting blank lifting, in particular to a casting blank self-stabilizing lifting device which comprises a fixed base, a rotating shaft, a stable lifting mechanism and an anti-reverse mechanism. According to the stable lifting mechanism designed by the invention, the conveying angle of the chain is adjusted according to the height required to be lifted by the adjusting group, so that the height adjusting effect is achieved, and the same casting blank lifting device can be lifted at different heights; meanwhile, the stabilizing frames on the left side and the right side of the chain support the chain through cooperation of supporting grooves and supporting rollers, so that the impact load bearing capacity of the chain is enhanced, the service life of the chain is prolonged, and meanwhile the stability of the casting blank in the lifting process is improved; and the problem that the stability of the casting blank in the lifting process is poor due to the fact that the casting blank lifted on the upper side shakes due to impact force generated when the casting blank falls onto the bearing base is solved.

Description

technical field [0001] The invention relates to the technical field of billet lifting, in particular to a billet self stabilizing lifting device. Background technology [0002] Billet is the product obtained from the molten steel produced by the steel-making furnace after casting by the continuous caster. From the appearance, it is mainly divided into the following types: slab, square billet, rectangular billet and round billet. In the iron and steel industry, the produced billet needs to be transported from the continuous casting workshop to the steel rolling workshop. In the process of transportation, the billet often needs to be lifted and transported due to the different layout heights of the two workshops. [0003] The Chinese patent with Announcement No. cn208994495u discloses a slab vertical lifting device. The device drives the chain from bottom to top through a sprocket. The slab is placed on the slab support device and lifted up with the chain. [0004] The above device...

AI Technical Summary

Problems solved by technology

[0004] The above device has the following problems when lifting the slab: 1. The sprocket chain is used to transport the slab, and when the slab falls to the slab supporting device on the lifting device chain, it is easy to produce an impact during the falling process. force, resulting in a reduction in the fatigue strength of the chain, resulting in a shortened service life of the chain

[0005] 2. When the sprocket chain is used to transport the billet, the chain is prone to deformation during the conveying process, and the chain with unlimited support is easy to drive the billet to shake during the conveying process, which makes it difficult to stabilize the billet. Reduced safety for conveying, slab lifting

[0006] 3. The lifting height of the above-mentioned slab vertical lifting device is fixed, and it is difficult for the same slab lifting device to lift to different heights, resulting in the problem that the use range of the slab lifting device is single
