Description

Technical Field

[0001] The utility model relates to the technical field of steel coil transportation, in particular to a steel coil fixing device for a freight car. Background Art

[0002] Steel coils, also known as rolled steel, are formed into coils by hot pressing and cold pressing of steel. For the convenience of storage, transportation, and various processing, the formed coils are mainly hot-rolled coils and cold-rolled coils. The weight of a steel coil is usually more than 10 tons, and its own weight is relatively heavy.

[0003] After being manufactured, steel coils are generally transported by freight cars. During transportation, fixing brackets are used to fix the steel coils to make the transportation process of the steel coils stable and to ensure the steel coils are stable under the inertia generated by sudden braking.

[0004] A fixing device for a steel coil on a transport vehicle proposed according to the publication number (CN216101794U) includes four fixing bases, which constitute the steel coil fixing device. One end face of the fixing base has a contact surface corresponding to the steel coil. The fixing base has a through hole, and a longitudinal control tube can be inserted into the through hole. Through the above components, when transporting the steel coil fixing device, it has the characteristics of time-saving, labor-saving, convenient loading and unloading, and reusable, increases the safety strength, improves the transportation efficiency, reduces the transportation cost, and gradually realizes the modern transportation mode.

[0005] However, in the above solution, only the fixing device is used to fix the steel coil, and no straps are used for fixing. Without the straps for fixing, the steel coil may slide or roll during transportation due to factors such as inertia, vehicle speed change, and road surface bump. Especially during emergency braking or turning, this risk is more obvious. However, the above solution only adopts one fixing method, which easily causes certain risks to the steel coil during transportation. Content of the Utility Model
