Background
After the finished steel coil is obtained from the production of the strip steel, the steel coil is usually transported by a crane. The existing travelling crane load capacity of a certain steel rolling mill of the horse steel is limited, and a travelling crane clamp is needed when a strip steel coil is hoisted, but the weight of the travelling crane clamp is usually about 3 tons; when the travelling crane carries the travelling crane clamp, the actual maximum load capacity of the travelling crane is greatly reduced. Due to production reasons, when the weight of some steel coils is close to the maximum load capacity of a travelling crane, travelling crane clamps cannot be used for hoisting, and hoisting transportation is usually carried out by adopting hanging strips. In the process of using the hanging strip to carry out steel coil lifting transportation, as the hanging strip is stressed in a triangular trend, and the end part of the strip steel is in a shape of blocking the triangle of the hanging strip, great stress concentration is generated at the end part of the strip steel, extrusion deformation is generated, the lifting influence of the condition on a wide automobile plate or a soft steel coil is great, and the generated lifting waste product also influences the economic benefit of enterprises.

In order to solve the problem that exists, the utility model provides an protection device that prevent coil of strip internal diameter and hang and hinder, when the device cooperation suspender carries out the coil of strip handling, avoid coil of strip top to produce stress concentration effectively to avoided the coil of strip to be destroyed, improved economic benefits.
In order to realize the above-mentioned purpose, the utility model discloses a following scheme, including coil of strip and suspender, handling instrument is "L" shape, handling instrument includes diaphragm and riser, the lower extreme of riser and the edge weld of diaphragm form the junction, the junction includes coil of strip contact surface and suspender contact surface, the interior anchor ring of coil of strip is being pasted to the diaphragm upper surface, the terminal surface of coil of strip is being pasted to the riser left surface, the suspender is pasting diaphragm lower surface and riser right-hand side.
step by step, the diaphragm overcoat has the protective sheath, the interior anchor ring of coil of strip is being pasted to the protective sheath upper surface, the protective sheath lower surface is being pasted to the suspender, the protective sheath cooperatees with the diaphragm shape.
step by step, it has the through-hole to open on the diaphragm, the through-hole intussuseption of diaphragm is filled with strong magnetic material, the inside of protective sheath is inlayed and is had strong magnetic material.
, the protective sheath is a polyurethane material.
, the transverse plate is an arc-shaped plate, and the lower end of the vertical plate is welded with the arc-shaped edge of the transverse plate to form a joint.
, the contact surface of the sling at the joint is provided with a sling groove for accommodating the sling.
, the steel coil contact surface and the sling contact surface at the joint are both arc surfaces.
Prevent that coil of strip internal diameter from hanging the protection device who hinders, when the device cooperation suspender carries out the coil of strip handling, avoid coil of strip top to produce stress concentration effectively to avoided the coil of strip to be destroyed, improved economic benefits.
