Problems solved by technology

The sheath with diameter adjustment mechanism can effectively solve the problem of unreliable fixation caused by the insertion of the steel coil sheath into the inner ring of the steel coil with a larger diameter than the steel coil, and also avoids the steel coil sheath being rubbed by the spreader. It is easy to drop, and also avoids the friction between the sheath and the inner ring of the steel coil

Embodiment 1

[0031] Embodiment 1: see Figure 1-5, a steel coil sheath with a diameter reducing mechanism, comprising a circular sleeve 11 and a hollow disc base 12, the inner diameters of the circular sleeve and the hollow disc base are equal and connected into a whole body, the steel coil sheath It also includes a diameter-reducing mechanism, which includes a threaded rod 314 inserted into the through hole 112 with a 90-degree handle 31, and the handle is provided with a positioning pin 311; the 90-degree handle adopts a 90-degree shape. The reason is that the operator can hold the handle with his hand to operate the variable diameter mechanism. The operation is smooth and labor-saving. The second function is that the 90-degree handle is parallel to the base surface of the steel coil sheath disc, and can be positioned and stored in the sheath through the positioning pin on the handle. The fan-shaped groove on the base of the disc will not protrude outward, and will not be damaged by acci...

Embodiment 2

[0033] Embodiment 2: The specific process of inserting the diameter reducing mechanism into a steel coil larger than its diameter.

[0034] see Figure 4 , Figure 5 , the steel coil sheath circular sleeve 11 with a diameter-changing mechanism is inserted into the inner ring of the steel coil 2 that is larger than its diameter, and when it cannot be fixed stably, rotate the steel coil sheath 1 until the handle 31 of the threaded rod 314 is vertical At the ground position and the open hollow body 32 falls on the bottom of the inner ring of the steel coil 2. At this time, the sheath is lifted to make the sleeve 11 contact with the top of the inner ring of the steel coil 2, and then the handle 31 of the threaded rod 314 is removed from the inner ring of the sheath. The disc base 12 fan-shaped groove 121 positioning hole 122 is drawn out, the handle 31 is rotated clockwise, the hollow body 32 and the elastic wear-resistant rubber skin 321 fixed on the threaded rod 314 also rotate...

Abstract

A steel coil sheath with a diameter-changing mechanism comprises a circular sleeve (11) and a hollow disc pedestal (12), and is characterized in that: the circular sleeve and the hollow disc pedestal are same in internal diameter and connected with each other for formation of a through body; the steel coil sheath also comprises the diameter-changing mechanism; a through hole (112) is disposed between the inner wall and the outer wall of the sleeve (11); and the through hole (112) penetrates the sleeve (11) and the disc pedestal (12). By using elastic folding of elastic wear-resistant rubber leather for diameter increasing, the steel coil sheath is applicable to lifting of steel coils with different specifications of internal diameters; by employing the elastic wear-resistant rubber leather and utilizing the support and tension of the elastic wear-resistant rubber leather, the diameter-changing mechanism of the sheath helps to make the sheath tightly contacts the inner ring of the steel coil, reduce the fraction between the sheath and the steel coil inner ring, alleviate shock caused by bump of a suspender to the steel coil and prevent the sheath from falling; the diameter-changing mechanism of the sheath is capable of rotating and opening, and also capable of shrinking to a diameter same with the diameter of the sleeve; and the steel sheath with the diameter-changing mechanism is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a steel coil sheath, in particular to a sheath which has a sheath diameter adjustment mechanism and can prevent the steel coil from colliding with the steel coil when the steel coil is hoisted, and belongs to the field of mechanical technology. Background technique [0002] The thickness of the incoming material and the finished steel strip in the cold rolling mill is relatively thin, and the steel coil is collided with the spreader when it is hoisted. It is inevitable to damage the steel coil when the inner ring of the steel coil is damaged. Due to the thin thickness of the steel strip, scratches and impact marks will affect the product quality and cause economic losses. [0003] After searching, there are many methods and equipment for steel coil protection in the prior art. For example, the protective cover in the specification of Chinese patent CN00217887.7 "Protective sleeve for steel coil packaging" is mainly us...
