Problems solved by technology

These hoisting work currently mainly rely on cranes, ferry cars or elevators in the workshop for hoisting with the help of magnetic suction cups, gravity hooks, gravity clamps, steel wire ropes, rigging, synthetic fiber slings and other components; during the hoisting process, manual labor is required Auxiliary hooking operation not only requires a lot of manual intervention and low efficiency, but also may cause the hook to be loose due to inadvertent manual operation, posing a certain safety risk

Abstract

The invention provides an automatic grab hook lifting appliance for I-shaped steel. The automatic grab hook lifting appliance comprises a grab hook body, and the grab hook body comprises a connectingpart, a grab hook arranged on the lower part of the connecting part in a hinged mode, and locking pieces arranged on the two sides of the connecting part in a mirroring mode; and the locking pieces each comprise an idler wheel arranged on the connecting part, a positioning piece arranged on the side face of the connecting part, a pin shaft arranged on the positioning piece, a locking hook arrangedon the pin shaft, and a rocker arm arranged between the idler wheel and the pin shaft, torsional springs are arranged on the pin shafts, one ends of the torsional springs abut against the positioningpieces, the other ends of the torsional springs abut against the locking hooks, locking shafts are arranged on the two sides of the grab hook correspondingly, the locking hooks are movably arranged on the locking shafts, and the inner edge and the outer edge of the grab hook are each in an arc shape. Compared with the prior art, the locking structure is simple, the locking state is firm, the security risk of hoisting of the I-shaped steel is reduced or avoided, and the functions of stable moving, efficient working, automatic hooking and automatic locking are achieved; and during constructionoperation, manual hooking for fixing is not needed, manual intervention is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an automatic grab hook hanger for I-beams. Background technique [0002] I-beam is a relatively common material in the production of steel components in steel structure processing plants; on the assembly line of the processing plant, it is necessary to hoist the I-beam or steel components to the welding station for welding of frames or panels. These hoisting work currently mainly rely on cranes, ferry cars or elevators in the workshop for hoisting with the help of magnetic suction cups, gravity hooks, gravity clamps, steel wire ropes, rigging, synthetic fiber slings and other components; during the hoisting process, manual labor is required Assisting in the hooking operation not only requires a large amount of manual intervention and is inefficient, but it is also very likely that the hook will not be strong due to careless manual operation, posing a certain safety risk. Ther...
