Abstract

The invention discloses a rubber protection device for hoisting a cold-rolled steel coil. The rubber protection device comprises steel plate protection layers, pull rods, steel cylinder protection sleeves, magnet positioning frames, springs, steel cylinders, vertical steel plates, suction claw protection layers, magnet suction claws and arc-shaped bearing plates, wherein the lower ends of the vertical steel plates are welded at one ends of the arc-shaped bearing plates; the steel plate protection layers wrap the vertical steel plates and the arc-shaped bearing plates; the steel plate protection layers on the outer sides of the arc-shaped bearing plates are in contact with the inner walls of holes of the hoisted steel coil; the steel plate protection layers on the inner sides of the vertical steel plates are in contact with the side wall of the hoisted steel coil; at least two steel cylinders are welded at the upper ends of the vertical steel plates; the springs are arranged in the steel cylinders; the lower ends of the springs are pressed against the vertical steel plates, and the upper ends of the springs are pressed against the pull rods; the pull rods extend out of the steel cylinders; the upper ends of the pull rods are bent towards the outer circumferential surface of the hoisted steel coil; the magnet positioning frames are welded at the upper ends of the pull rods; the magnet suction claws are arranged in the magnet positioning frames; and the outer sides of the steel plate protection layers, the steel cylinder protection sleeves and the suction claw protection layers are positioned on the same straight line.

Description

technical field [0001] The invention relates to a clamp sheath, in particular to a rubber protective device for hoisting cold-rolled steel coils. Background technique [0002] The quality of cold-rolled products largely affects the product quality level of the entire steel mill. The process of cold-rolled products is complicated, the equipment investment is large, the technical content is high, and the product quality itself has high performance and appearance requirements. The difference in appearance quality directly affects As far as the quality level of products is concerned, it is common for steel mills to downgrade cold-rolled plates by customers every year because of their appearance quality, which has virtually caused huge waste of quality and value loss. The market value of the product is tens of millions of yuan. Therefore, improving the surface quality of cold-rolled steel coils is a positive practice for the improvement of quality and efficiency advocated by the ...
