Abstract

The invention provides a bar slowly-cooled material lifting appliance with a self-closing release function and an application method, and belongs to the technical field of lifting appliances. The lifting appliance comprises a cross beam component, a pocket claw component, a lifting rod component, a drag hook, a lifting rotating component and the like, and can automatically clamp and release a bar material and a slow cooling material. Through the lifting of the cross beam component and the draw hook, the draw hook hooks a pocket claw, so that the pocket claw can be opened; and the draw hook is separated from the pocket claw, so that the pocket claw can be closed. The pocket claw comprises a pair of grabhooks which are connected in a crossed and pivoted mode; when the bars are moved, the clamping force of the lifting appliance is larger along with lifting of the lifting appliance, and the bars cannot fall off. The lifting appliance is simple in structure and safe and reliable in the using process, and manual hooking and unhooking are not needed; and meanwhile, a large bending phenomenon generated by high-temperature slow cooling steel is reduced.

Description

technical field [0001] The present application relates to the technical field of hoisting slings, in particular, to a slow-cooled bar sling with a self-closing and releasing function. Background technique [0002] In the production process of special steel, some steel grades need to be slowly cooled in the foundation pit according to the production process standard before they can be delivered and manufactured. Hang it into the pit for natural cooling. Due to the stacking of high-temperature bars, the lower bar is easily bent by external forces, which makes it very difficult to straighten the bars after slow cooling; Very large, difficult to operate, especially in summer, the working environment is particularly harsh. [0003] After retrieval, Chinese patent CN201921557916.1 discloses a special spreader for rods or pipes, including a cross-shaped first connecting rod assembly, the first connecting rod assembly includes a first connecting rod and a second connecting rod, an...
