Description

Technical Field

[0001] This utility model relates to the technical field of steel coil transportation equipment, specifically a device for preventing steel coils from loosening. Background Technology

[0002] Steel coils, also known as rolled steel, are a common form of semi-finished product in the steel industry. They are primarily made of carbon steel, stainless steel, and alloy steel. Steel is produced by hot-rolling, cold-rolling, or other forming processes, and then winding it into a tightly rolled, regular cylindrical shape. This shape not only saves storage space and facilitates long-distance transportation but also allows for subsequent deep processing steps such as cutting, stamping, and welding. Steel coils are widely used in numerous fields, including construction, automobile manufacturing, machinery manufacturing, shipbuilding, petrochemicals, and bridge construction. In construction, steel coils are often used to manufacture steel structures and reinforcing bars; in automobile manufacturing, they are mainly used to produce body and chassis components; and in machinery manufacturing, steel coils are an indispensable raw material for manufacturing various mechanical equipment and parts.

[0003] However, existing steel coils are usually directly strapped to trucks during transportation. When passing through bumpy sections of road, the steel coils are prone to loosening due to shaking. This shaking may not only cause the steel coils to shift during transportation, increasing transportation risks, but may also damage the trucks and surrounding facilities, and even cause traffic accidents, posing a serious threat to the safety of people and property.

The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 4In this embodiment of the present invention, a device for preventing loosening of a steel coil includes: a frame 1 and a steel coil 2. A cylinder 3 is concealed above a cylinder frame fixed to the side of the frame 1. A telescopic rod 4 is provided inside the frame 1, and the cylinder 3 is connected to the telescopic rod 4. A first arc-shaped abutment 5 is fixed to the other end of the telescopic rod 4. The cylinder 3 is mounted on the cylinder frame on the side of the frame 1, and the telescopic rod 4 is telescopically moved by air pressure control. When the cylinder 3 works, the telescopic rod 4 pushes the first arc-shaped abutment 5 to press against one side of the steel coil 2, providing an initial fixing force. A crossbar 6 is fixed to the other side of the frame 1. A sliding block 7 is slidably connected to one end of the crossbar 6. Two sets of sliding blocks 7 slide away from or towards each other on the crossbar 6. A spring 8 is fixedly connected to one side of the sliding block 7, and a movable rod 9 is hinged to the other side of the sliding block 7. A hinge 10 is hinged to the other end of the movable rod 9. There are two sets of sliding blocks 7, springs 8, movable rods 9 and hinges 10. A second arc-shaped abutment 11 is fixedly connected to the side of the hinge 10. The sliding block 7 on the crossbar 6 can slide on the crossbar 6 through the elastic action of the spring 8 to accommodate steel coils 2 of different diameters. The sliding block 7 is connected to the second arc-shaped abutment 11 through the movable rod 9 and the hinge 10. When the steel coil is placed in the frame, the second arc-shaped abutment 11, under the elastic force of the spring 8, together with the first arc-shaped abutment 5, clamps the steel coil to ensure that the steel coil will not shift due to shaking. The first arc-shaped abutment 5 and the second arc-shaped abutment 11 are matched in size.

[0022] Reference Figure 3 An inflatable fixing bladder 12 is installed inside the frame 1, and an inflation port 13 is fixed to the side of the frame 1. The inflatable fixing bladder 12 is connected to the inflation port 13, and the inflatable fixing bladder 12 is placed inside the center circle of the steel coil 2. The inflatable fixing bladder 12 inside the frame 1 expands after being inflated through the inflation port 13 and fills the center circle of the steel coil 2, providing additional support for the steel coil and further enhancing its stability.

[0023] Reference Figure 2 A frame door 14 is hinged to one side of the frame 1, and a latch 15 is fixed to the other side of the frame 1. A latch hook that matches the latch 15 is fixed to the side of the frame door 14. There are two sets of latches 15 and their matching latch hooks, and they are installed on the same side of the frame 1 and the frame door 14. The frame door 14 on one side of the frame 1 is connected to the main body of the frame 1 by hinge. After the frame door 14 is closed, the latch 15 and the latch hook are used together to lock the frame door 14 securely, ensuring the safety of the entire device during transportation.

[0024] Reference Figure 1 Two sets of reinforcing rods 16 are fixed at the top and bottom of the frame 1, which can be used to limit and support the upper and lower round ends of the steel coil 2. The reinforcing rods 16 set at the top and bottom of the frame 1 not only enhance the overall structural strength of the frame, but also effectively support the upper and lower round ends of the steel coil, reducing the risk of deformation or loosening caused by uneven weight distribution.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] The working principle of this utility model is as follows: First, the air-filled fixing bladder 12 is inflated through the air inlet 13 to expand it to an appropriate size, ready to receive the steel coil. At the same time, the cylinder 3, telescopic rod 4, spring 8 and other components are checked to ensure they are in normal working condition. The frame door 14 is opened, and the steel coil 2 is carefully placed into the frame 1, ensuring that the center of the steel coil is aligned with the air-filled fixing bladder 12. The cylinder 3 is activated, and the telescopic rod 4 pushes the first arc-shaped abutment 5 to press tightly against one side of the steel coil. At the same time, the spring 8, through the action of the sliding block 7, the movable rod 9 and the hinge 10, causes the second arc-shaped abutment 11 to move towards the steel coil. Move to the other side until it clamps the steel coil together with the first arc-shaped abutment 5. After checking that the steel coil is secure, close the frame door 14 and lock it with the latch 15 and latch hook. Confirm that all fixing devices are in place and locked to ensure that the steel coil will not loosen or shift during the entire transportation or storage process. After the device is ready, the transportation or storage operation of the steel coil can be carried out. During transportation, if the steel coil shakes, the second arc-shaped abutment 11 will feed the force back to the sliding block 7 through the movable rod 9, compressing the spring 8 to relieve the force generated by the shaking and ensure the stability of the steel coil.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
