Description

Technical Field

[0001] The utility model relates to the technical field of steel coil clamps, in particular to a single-side vertical coil clamp for steel coils. Background Art

[0002] Steel coil, also known as coil steel, is steel that is hot pressed or cold pressed into a coil shape. It is convenient for storage and transportation and for various processing.

[0003] Under existing conditions, lifting machines are often used to facilitate the movement and use of steel coils. However, the grippers used in traditional lifting machines are mostly unilateral clamping structures, such as a steel coil clamp disclosed in announcement number CN205271776U. The upper limit rod and the upper limit setting in the steel coil clamp can increase the falling speed of the steel coil clamp when lifting the steel coil, and can also avoid the secondary damage caused by the steel coil clamp impacting the upper part of the steel coil. Because only a single clamping structure is used to clamp and fix the steel coil with huge volume and weight, the clamping measure has the problem of a single force point, which can easily cause the vertical steel coil to deflect or even tilt and fall, and the horizontal clamping action is difficult to overcome the large weight, which easily leads to vertical falling accidents during the handling process.

[0031] The functional principle of the utility model can be explained through the following operation modes:

[0032] Place the steel coil vertically;
