A steel coil anti-loosening device

Abstract

The invention discloses a steel-coil loose-preventing device. The steel-coil loose-preventing device comprises a round cover plate and a zigzag rotating handle, wherein the cover plate is matched with the end part of a steel coil; the rotating handle is arranged on the plate surface of the cover plate far away from the steel coil; the plate surface of the cover plate, which faces to one side of the end part of the steel coil, is provided with a ring-shaped groove; the ring-shaped groove is divided into a central round-platform part and an outer-edge cover edge part; a round groove is arranged at the center of the round-platform part; a thread through hole is formed at the center of the round groove; three top parts are arranged in the round-platform part and are uniformly distributed in a radial manner by adopting the center of the round-platform part as the center; one end of each top rod, which extends out of the round-platform part, is fixedly provided with an arc-shaped top plate which are attached with the outer wall of the round-platform part; the end surface of one end of each top rod, which in the round groove of the round-platform part is an arc surface; the top rods are provided with springs, and the two ends of the springs are respectively fixed on the round-platform part and the top rods; the rotating handle comprises a thread part, a middle connecting part and a handle; the thread part is matched with the thread through hole at the center of the round-platform part; and the end part of the thread part is conical. The steel-coil loose-preventing device disclosed by the invention has the advantage that the steel coil can be prevented from being loosened by extruding force.

Description

technical field [0001] The invention relates to the technical field of steel coil anti-loosening equipment, in particular to a steel coil anti-loosening device. Background technique [0002] After the steel coil is wound, the starting end and the end are not fixed and it is easy to loosen. The existing anti-loosening method is to use a flexible structure similar to a packing belt to surround the steel coil from the inside to the outside. The problem with this loosening method is that it is flexible. The structure cannot fit tightly with the surface of the steel coil to generate pressure to prevent the coil from loosening, and this flexible structure is easy to loosen during the transportation of the steel coil. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a steel coil anti-loosening device, which can prevent the steel coil from becoming loose through extrusion force. [0004] In order to achieve the above-m...
