Description

Electric horizontal coil clamp

Technical Field

The utility model relates to the technical field of hoisting equipment, in particular to an electric horizontal coil clamp.

Background

In steel enterprises, coil of strip is delivered to warehouse and delivered out of warehouse by an overhead traveling crane through controlling an electric horizontal coil clamp hung on a lifting hook. For a long time, the appearance damage caused by collision of electric horizontal coil clamps or rubbing of steel coils often occurs in the hoisting operation process, so that quality objections are caused, the yield of products is reduced, and the cost is increased. Through on-site observation and analysis, the direct reason for causing the damage of the steel coil is that although two clamp arms of the electric horizontal coil clamp are in an open state, the clamp claw parts on the clamp arms are easy to collide with the steel coil or scrape and rub the steel coil at the descending stage when the steel wire rope hoisted by the overhead travelling crane hangs the electric horizontal coil clamp through the hook group and the ascending stage after the electric horizontal coil clamp is separated from the steel coil after the hoisting is finished. Further analysis, the main reason is that although the distance between the two jaws is about 200mm-300mm larger than the width of the steel coil, the distance between the jaws and the end face of the steel coil is about 100mm-150mm in an ideal centering state, in practice, in a fast-paced production process, during hoisting, the visual error of operation and the skill level affect the control precision of the crown block and the electric clamp, the stability of the electric clamp under the traction of a steel wire rope is not good, and the centering deviation between the electric horizontal coil clamp and the steel coil is often larger than 150mm, so that the distance between the jaws and the steel coil cannot completely meet the requirement of the centering error between the electric horizontal coil clamp and the steel coil. If the opening travel distance of the clamp arm of the electric clamp is increased by transformation, firstly, the production rhythm is restricted, and the production efficiency is reduced; secondly, the electric horizontal coil clamp can collide other steel coils due to the increase of the width when being hoisted in the storage area in which the steel coils are vertically and horizontally arranged; in addition, when the electric horizontal coil clamp is used for off-line warehousing and hoisting of the hot rolled steel coil, the hot rolled steel coil is generally in a high-temperature environment, so that equipment with an electric control device arranged in a jaw area cannot be normally used in the environment.
