Steel coils, also known as coiled steel, are rolled by hot pressing and cold pressing, are convenient to store and transport, and are processed into steel plates, steel strips and the like. At present, lifting mechanisms adopted when domestic vertical steel coils are lifted, carried and transferred are generally lifting hooks, the shape types of the lifting hooks are various, and the pincer-shaped lifting hooks are one of the lifting hooks.

The clamp-shaped lifting hook is widely used, clamp walls at two sides of the clamp-shaped lifting hook can automatically stretch and retract under electric control, and hook feet at the bottom of the clamp walls can extend into the steel coil from two sides to hook and lift the steel coil. When the cold-rolled sheet is in work, cold-rolled sheets produced by iron and steel companies are rolled into steel coils on production equipment, and the inner diameter of the steel coils is hooked by a clip-on lifting hook for travelling crane and lifted to a warehouse. However, the thickness of the cold-rolled sheet is quite thin, generally only 0.12-0.24 mm, and the dead weight of the steel coil is about 15 tons, so that the inner ring of the steel coil is easy to generate an indentation when the pincerlike lifting hook hooks the inner diameter of the steel coil to lift, 3% -5% of waste products are generated on the steel plate, material waste is caused, and the utilization rate of the steel plate is reduced. There is a need for an improvement to solve the above-mentioned problems.

Related patents on steel coil lifting mechanisms have been disclosed through searching. For example, chinese patent application No. CN201720676917.2 discloses a horizontal coil lifting appliance with protection, comprising: the main beam, the lifting lug and the two clamp arms are oppositely provided with clamp feet at the end part of the clamp arm far away from the main beam; further comprises: the protecting devices are symmetrically arranged on the two clamp arms and face to the clamping direction of the horizontal coil, and the protecting devices can perform telescopic displacement on the clamp arms under the action of external force. The application is characterized in that the rollers are arranged on the clamp arms and the clamp feet to protect steel coils, but the whole structure is relatively complex in design, relatively high in manufacturing cost and inconvenient to install, and the sliding grooves are formed in the clamp arms, so that the structural strength of the clamp arms is reduced, the whole service life of the lifting appliance is influenced, and the whole design is to be further improved.
