Description

Technical Field

[0001] The present invention relates to the field of steel coil transportation, and in particular to a steel coil fixing device. Background Art

[0002] Currently, long-distance transport of steel coils is typically carried on semi-trailers, where the coils are placed upside down and secured with front and rear wooden wedges. This method of transport has proven to be dangerous. Steel coils typically weigh 15-30 tons, and when the transporter brakes suddenly or experiences bumps, the coils can break free from the wooden wedges due to inertia, rolling forward or falling off, creating a dangerous situation.

[0003] As a result, many special transport vehicles or fixed devices for transporting steel coils have emerged. Special transport vehicles are modified from the truck bed to specifically load steel coils. They are expensive and have a single type of goods. Some steel coil fixing devices have complex structures, numerous transmission components, high costs, and are difficult to store.

[0004] Chinese patent publication CN214355753U, titled "A Steel Coil Fixing Device for Trucks," discloses a steel coil fixing device in which the steel coil is placed on the arc-shaped surfaces of symmetrically arranged fixing blocks. The blocks are connected via fastening mechanisms adapted to fit through holes in the fixing blocks. This single-minded steel coil fixing method provides only limited support in the direction of rolling. This method, facing the complexities of transportation, fails to effectively guarantee the effectiveness and safety of the steel coil fixing device during transportation, resulting in a low safety factor.

[0005] In the Chinese patent document CN 213736598 U, entitled "A Steel Coil Fixing Device," a steel coil fixing device is disclosed: comprising a support mechanism, a transmission mechanism, a drive mechanism, a bracket mechanism, a clamping mechanism, and a limiting mechanism; wherein the transmission mechanism is disposed on the support mechanism and is used to transmit the steel coil; the drive mechanism is disposed on one side of the transmission mechanism and is used to drive the bracket mechanism to move; the bracket mechanism is disposed on one side of the drive mechanism and is used to support the clamping mechanism; the clamping mechanism is disposed on the support mechanism and is used to clamp the steel coil; and the limiting mechanism is disposed on the support mechanism and is used to fix both sides of the steel coil. This steel coil fixing device has a complex structure, many transmission components, high cost, and is not conducive to storage. Summary of the Invention

[0006] The object of the present invention is to provide a steel coil fixing device, which has a high safety factor, low manufacturing cost and is convenient for storage.

[0011] Furthermore, the limit blocks are two in number, each having a second connecting shaft disposed on its axial end face along the steel coil. A second pull rod is disposed between the first and second connecting shafts. The second pull rod can provide a force perpendicular to the axial direction of the steel coil to prevent the steel coil from rolling, while also providing an axial force to prevent axial displacement.

A group of first pull rods 310 is symmetrically provided on both sides of the bottom plate 100 along the axial direction of the steel coil, and each group of first pull rods 310 consists of two. One end of the first pull rod 310 on the same side is connected to the first connecting shaft 712 at the corresponding end, and the other end is connected to the corresponding fixed block 210 through the first connecting member 220.

The bottom plate can also be the loading platform of the transport vehicle, and the fixing block is fixedly connected to the loading platform of the transport vehicle through fasteners.

[0042] The material of each component of the steel coil fixing device provided in the present invention is steel material in the prior art. Preferably, the limit block 250 and the winding member 711 can be made of wood. The surface hardness of wood is lower than that of steel. With the same volume, the weight is lighter, which is conducive to better protection of the appearance of the steel coil and improvement of the support and protection performance of the steel coil 710. Of course, the components of the steel coil fixing device in the present invention can also be made of other materials similar to steel and wood in the present invention.

By adopting the first pull rod arranged between the base plate and the first connecting shaft and the second pull rod arranged between the limit block and the first connecting shaft, an axial supporting force is provided to the steel coil to prevent the steel coil from axial displacement, which effectively increases the firmness and safety factor of the steel coil fixation. Since mechanical connection structures are adopted between the base plate, the fixing block and the first connecting member, and between the first pull rod and the first connecting member and the second connecting member, disassembly and assembly are simple and storage is convenient. The limit block, the first pull rod, the second pull rod and the connecting rod are all symmetrically arranged with a simple structure, which can realize standard and modular production, low cost, and is conducive to promotion and application.
