Single-hook and double-hook conversion type hook head of hoisting equipment

Abstract

The invention discloses a single-hook and double-hook conversion type hook head of hoisting equipment. The single-hook and double-hook conversion type hook head comprises a double-hook hook head connected to the hoisting equipment, wherein the lower end of the double-hook hook head is detachably connected with a single-hook hook head; two connecting pieces are arranged on the upper portion of the single-hook hook head, and when the single-hook hook head is connected to the double-hook hook head, the two connecting pieces are clamped in grooves of the double-hook hook head correspondingly; and each connecting piece is a convex hanging rod, a hook or a hanging ring. According to the single-hook and double-hook conversion type hook head of the hoisting equipment, the utilization rate of the 80T crown block in the production process can be improved; and particularly, after finished steel coil transportation equipment breaks down, an anchor-head-hook hook head can be quickly converted into the single-hook hook head, and the single-hook hook head can be matched with a C-shaped lifting appliance to participate in the operation activity of lifting finished steel coils from a coiling machine, so that the production rhythm is stabilized, the production guarantee is improved, the accident potential of production interruption is completely eradicated, and stable and smooth production is ensured.

Description

Technical field [0001] The present invention belongs to the technical field of lifting equipment, and more particularly to a single-double hook-shaped hook-hook-hook-shaped hook. Background technique [0002] Carbon steel sheet continuous casting joint production line, the production process is that the slab is preheated by the heating furnace, the rolling unit rolling, and the laminar flow is cooled to enter the underground winding machine to become a finished steel coil, and finally use the finished steel roll transport equipment transmission. Go to the beam and wait for the wagon to lifting. And the production of rhythm production lines in the production line is compact, the hoisting operation is frequent, the work content is mainly: the roll of the rolling unit with anchor hook hook hook, and uses two 40t with single hook Trolley lifting finished steel roll is main. During the daily production process, once the failure cannot be used, once the fault is unusable, it is necessa...

AI Technical Summary

Problems solved by technology

During the production process, an average of two coils of finished steel coil G are rolled every 6 minutes. After the failure of the finished steel coil transportation equipment, two 40T cranes are hoisted from the coiling pit to the finished steel coil storage area for about 6-8 minutes. Left and right, so if the finished steel coil transportation equipment fails, when the finished steel coil G is hoisted from the coiling pit to maintain production, the round-trip time of the two cranes cannot meet the production rhythm, and in severe cases, it will cause production interruption accidents
