Rolled plate hoisting gasket

Abstract

The invention relates to a rolled plate hoisting gasket, belonging to the technical field of hoisting tools. The gasket comprises a length of arc-shaped bending plate mainly identical to an inner ring of the rolled plate, the bending plate is provided with a vertical baffle along an arc side thereof, an external arc surface of the bending plate and an inner surface of the vertical baffle are respectively provided with ferromagnets at intervals, and an inner arc surface of the bending plate is provided with a bump. In comparison with the existing rolled plate gasket, the gasket provided by theinvention has the following advantages that: 1) with the ferromagnets, the gasket can be closely attached to the inner ring of the rolled plate just by only a small length of the arc-shaped bending plate, and the gasket not only has small volume, low cost and convenient use, but also cannot fall off in the process of use; 2) the vertical baffle can further prevent a nylon hoisting belt from contacting an external end surface of the rolled plate, so that the external end surface of the rolled plate is protected; 3) with the bump, an extrusion force applied on the whole gasket by the hoisting belt can be transferred from a corner of the vertical plate to the bump, so that the extrusion force applied on the inner ring of the cold-rolled plate by the hoisting belt is further reduced, and abrasion of the bending plate and the corner of the vertical plate is avoided.

Description

technical field [0001] The invention relates to a protective liner used for preventing the indentation of the inner ring of the coil caused by a suspender during the hoisting process of a cold-rolled coil, and belongs to the technical field of hoisting equipment. Background technique [0002] At present, the hoisting of cold-rolled coils generally adopts the operation mode of balance beam and nylon sling. Indentations often appear on the inner ring of the cold-rolled coil after hoisting in this way. The reason is that the extrusion force of the nylon sling on the inner ring of the coil causes deformation on the surface of the coil. [0003] In order to avoid indentation damage of the plate coil during hoisting, hoisting fixtures are specially designed in the prior art. For example, the Chinese patent No. 200520027558.5 discloses a coiled plate vertical crane clamp, which utilizes the retractable tongue on the coiled plate to be clamped on the inner and outer rings of the co...

Problems solved by technology

But there is no connection between the expansion ring and the coiled plate, it is easy to fall off, and the damage to the coiled plate cannot be avoided; moreover, the expanded ring is an integral annular ring inserted into the inner ring of the entire coiled plate, so the volume of production is large and the cost is high , Inconvenient to use; In addition, the expansion ring is not suitable for the operation method of the balance beam and the nylon sling
