Description

Technical Field

[0001] The present invention relates to the technical field of steel coil transport vehicles, and in particular to a freight device and a freight method for protecting steel coils. Background Art

[0002] Steel coil is a cylindrical structure made of steel coils. It is a common form of steel in the manufacturing, processing and application process. It has a large mass and inertia. During the transportation of steel coils, in order to facilitate loading and unloading and avoid damage from bumps, its outer surface is usually placed on the transport vehicle;

[0003] However, since the steel coils are easily rolled or overturned due to inertia during transportation, thus causing transportation accidents and casualties, transportation personnel usually use a variety of methods to fix and protect the steel coils. One method is to set a slot device on the transport vehicle, which is a bracket, base, saddle or similar structure, so that the steel coils can fall into the slot device when loading, thereby limiting the displacement of the steel coils to a certain extent; however, in actual applications, the slot device has a very limited ability to limit the displacement of the steel coils. After being squeezed by the steel coils, it is easy to deform and fail. In addition, the same slot device is difficult to be used for steel coils of various specifications. When transporting steel coils of different specifications, the slot device also needs to be changed, which makes the purchase, installation, disassembly and storage of the slot device costly and inconvenient to use;

[0004] Another method is to modify the transport vehicle, such as setting a cargo box platform with grooves on the transport vehicle to limit the displacement of the steel coil; however, in actual application, modifying the transport vehicle is likely to involve illegal modification and other illegal acts, and my country's freight vehicles are usually multi-purpose, and the special vehicles modified to meet the needs of steel coil transportation have a single function and are expensive, which will greatly reduce the applicability of the modified vehicles;

[0005] The last method is that the transport personnel simply put wooden pads or wooden sleepers on both sides of the steel coils, and then use their own driving control technology to avoid the inertial rolling and inertial movement of the steel coils caused by sudden stops and turns of the vehicle during transportation. This method is very likely to cause transportation accidents and casualties. Summary of the invention

[0006] In view of the defects of the prior art mentioned above, the technical problem to be solved by the present invention is to provide a freight device and a freight method for protecting steel coils, which can effectively limit the inertial rolling and inertial movement of the steel coils during transportation, protect the personal safety of the transportation personnel, and avoid damage to the steel coils.

[0007] To achieve the above-mentioned objectives, the present invention provides a freight device for protecting steel coils, wherein the steel coil is arranged on a cargo platform of a freight vehicle, and a cab is also arranged on one side of the cargo platform. The freight device includes a plurality of flexible connectors and a plurality of energy absorbing structures arranged on the cargo platform. Energy absorbing structures are respectively arranged on both sides of any steel coil, and the energy absorbing structures are spaced apart from the steel coils. The energy absorbing structures include a plurality of filling components, each of which includes a filling bag and a filling material arranged in the filling bag. One end of the flexible connector is fixedly connected to the filling component of the energy absorbing structure, and the other end passes through the inner cavity of the steel coil and is fixedly connected to another filling component of the same energy absorbing structure.

[0008] Furthermore, the flexible connecting member is configured as a braided rope.

[0009] Furthermore, the filling material of the filling component is set to quartz sand.

[0010] Furthermore, the capacity of the filling bag is set to 25-50kg.

[0011] Furthermore, the number of filling components provided in the energy absorbing structure close to the cab side on the cargo platform is greater than the number of filling components provided in other energy absorbing structures.

[0012] The present invention also discloses a method for transporting a steel coil using the above-mentioned transport device. The method comprises the following steps:

[0013] S1. Put the filling material into the filling bag to form a filling assembly, and place the filling assembly near the freight vehicle for loading the steel coil;

[0014] S2. transport the steel coil to the cargo platform of the freight vehicle;

[0015] S3, transporting the filling components to the cargo platform of the freight vehicle, and stacking the filling components to form a plurality of energy absorbing structures, so that energy absorbing structures are respectively arranged on both sides of any steel coil, and the energy absorbing structures are arranged at intervals from the steel coil;

[0016] S4. Connect the steel coil to the filling component of the energy absorbing structure through a flexible connector, fix one end of the flexible connector to the filling component of the energy absorbing structure, and pass the other end through the inner cavity of the steel coil and fix it to another filling component of the same energy absorbing structure.

[0017] As described above, the freight device and freight method for protecting steel coils according to the present invention have the following beneficial effects:

[0018] 1. By setting up the freight device, the energy-absorbing structure does not directly contact the steel coil under normal conditions, so that the filling component and the loading and unloading process of the steel coil interfere with each other less. When loading the steel coil, the transportation personnel can either set the energy-absorbing structure on the cargo platform in advance or set the energy-absorbing structure after the steel coil is transported to the cargo platform. When unloading the steel coil, it is only necessary to untie the flexible connector connected to it to unload the steel coil. The operation is convenient and quick, saving time and labor costs.

[0019] 2. By using the energy-absorbing structure formed by the filling component, the energy-absorbing structure can be flexible and versatile, with strong applicability, and can be applied to steel coils of different specifications. There is no need to modify the freight vehicle, nor is there a need to connect the steel coil to the body structure of the freight vehicle, thereby avoiding damage to the body of the freight vehicle. At the same time, the materials of the energy-absorbing structure and the filling component are cheap and easy to obtain, and the implementation plan is simple and popular, without the need for complex processing and manufacturing processes and strict personnel configuration requirements.

[0020] 3. By using flexible connectors to pull the steel coils onto the energy-absorbing structure, additional friction is introduced, thereby reducing or limiting the accidental inertial movement of the steel coils during transportation. The energy-absorbing structure close to the cab side can serve as a buffer barrier to further protect the personal safety of the transportation personnel.

[0021] 4. By dispersing multiple energy-absorbing structures, compared with traditional mechanical restriction schemes, it can disperse and flatten the stress distribution of the cargo platform, avoiding accidents such as overturning, tipping over, and bending of the cargo platform during transportation.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0030] See also Figure 1 to Figure 2 The present invention provides a freight device for protecting steel coils, wherein the steel coil 5 is arranged on a cargo platform 1 of a freight vehicle, and a cab 2 is also arranged on one side of the cargo platform 1. The freight device comprises a plurality of flexible connectors 3 and a plurality of energy absorbing structures 4 arranged on the cargo platform 1. Energy absorbing structures 4 are respectively arranged on both sides of any steel coil 5, and the energy absorbing structures 4 are arranged at intervals from the steel coil 5. The energy absorbing structure 4 comprises a plurality of filling components, and the filling components comprise a filling bag and a filling material 7 arranged in the filling bag. One end of the flexible connector 3 is fixedly connected to the filling component of the energy absorbing structure 4, and the other end passes through the inner cavity of the steel coil 5 and is fixedly connected to the same energy absorbing structure 4. on another filling component; preferably, the energy absorbing structure 4 is formed by stacking a plurality of filling components, and the shape of the energy absorbing structure 4 is stacked into a trapezoid; preferably, the height of the energy absorbing structure 4 is lower than the height of the steel coil 5 lying horizontally on the cargo platform 1, and higher than the height of the center of the steel coil 5 lying horizontally on the cargo platform 1. When the transport vehicle makes an emergency stop or a sharp turn, the energy absorbing structure 4 can avoid destroying its overall structure due to inertial movement and affecting the restricting effect of the freight device; at the same time, the flexible connector 3 and the energy absorbing structure 4 have little conflict with the prior art, and can be implemented independently or as an auxiliary means together with other existing protection schemes.

[0031] The basic working principle of the freight device for protecting steel coils involved in the present invention is: by setting a flexible connector 3 and an energy absorbing structure 4, when the transport vehicle encounters unexpected situations such as sudden stop or sudden turn, resulting in the inertial rolling and inertial movement of the steel coil 5, under the traction of the flexible connector 3, the flexible connector 3 will drive the filling component to move accordingly with the movement of the steel coil 5, and the filling component can continuously consume the kinetic energy of the inertial movement of the steel coil 5 through friction resistance. Furthermore, multiple flexible connectors 3 can drive multiple filling components of the energy absorbing structure 4 to move accordingly, so that the shape of the energy absorbing structure 4 changes accordingly with the movement of the steel coil 5, effectively decelerating the inertial rolling and inertial movement of the steel coil 5, thereby reducing the harm and property loss caused by transportation accidents. At the same time, by arranging the energy absorbing structure 4 and the steel coil 5 at intervals, when the energy absorbing structure 4 is stacked into a trapezoidal shape by the filling components, it can prevent the steps formed by the filling components from becoming steps for the steel coil 5 during inertial rolling and inertial movement, thereby preventing the steel coil 5 from crossing the energy absorbing structure 4.

[0032] See also Figure 1 to Figure 2 The present invention is further described below with a specific embodiment:

[0033] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the flexible connector 3 is configured as a braided rope, the braided structure on its surface increases wear resistance, can provide good grip, and reduce the risk of sliding of the steel coil 5. At the same time, the braided rope is woven from multiple strands of fibers, has a tight structure, high tensile strength, and is soft and easy to bend, making it easy to operate and tie knots. Preferably, in other embodiments, the flexible connector 3 can also be configured as a hemp rope or other similar structures.

[0034] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the filling material 7 of the filling component is set to quartz sand. On the one hand, quartz sand is easy to obtain and store, and its purchase, use and maintenance costs are low, it has good economy, is friendly to individual freight drivers and small transportation companies, and is more conducive to promotion. On the other hand, quartz sand has a high hardness. When the steel coil 5 cannot avoid rolling, the quartz sand can continue to consume its energy and reduce the severity of the accident. Moreover, when the quartz sand accumulates, it can be squeezed by the steel coil 5 and can wrap the steel coil 5 as the contour of the steel coil 5 deforms, thereby avoiding damage to the steel coil 5 and protecting the steel coil 5 to a certain extent; preferably, water is poured on the surface of the filling component to make it moist, thereby increasing the mass and friction of the filling component; preferably, in other embodiments, the filling material 7 of the filling component can also be set to other similar solid granular materials.

[0035] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the capacity of the filling bag 6 is set to 25-50 kg, and filling bags 6 of different capacities can be flexibly set according to the specific specifications of the steel coil 5 and the actual area of ​​the cargo platform 1 of the freight vehicle.

[0036] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the number of filling components set in the energy absorbing structure 4 on the cargo platform 1 close to the cab 2 is greater than the number of filling components set in other energy absorbing structures 4, which can prevent the steel coil 5 from rushing towards the cab 2 due to inertial movement when the freight vehicle is accelerating or rear-ending, thereby protecting the personal safety of the transportation personnel.

[0037] See also Figure 1 to Figure 2 The present invention also discloses a method for transporting steel coils using the above-mentioned transport device. The method comprises the following steps:

[0040] S3, transporting the filling components to the cargo platform 1 of the freight vehicle, and stacking the filling components to form a plurality of energy absorbing structures 4, the shape of the energy absorbing structures 4 is stacked into a trapezoid, and the height of the energy absorbing structures 4 is lower than the height of the steel coil 5 lying horizontally on the cargo platform 1, and higher than the height of the center of the steel coil 5 lying horizontally on the cargo platform 1, and energy absorbing structures 4 are respectively arranged on both sides of any steel coil 5, and the energy absorbing structures 4 are arranged at intervals from the steel coil 5;

[0041] S4. Connect the steel coil 5 to the filling component of the energy absorbing structure 4 through the flexible connector 3. Fix one end of the flexible connector 3 to the filling component of the energy absorbing structure 4, and pass the other end through the inner cavity of the steel coil 5 and fix it to another filling component of the same energy absorbing structure 4.

[0042] As described above, the freight device and freight method for protecting steel coils according to the present invention have the following beneficial effects:

[0043] 1. By setting up a freight device, the energy absorbing structure 4 does not directly contact the steel coil 5 under normal conditions, so that the filling component and the loading and unloading process of the steel coil 5 interfere with each other less. When the steel coil 5 is loaded, the transportation personnel can either set the energy absorbing structure 4 on the cargo platform 1 in advance, or set the energy absorbing structure 4 after the steel coil 5 is transported to the cargo platform 1. When the steel coil 5 is unloaded, it is only necessary to untie the flexible connector 3 connected thereto to unload the steel coil 5. The operation is convenient and quick, saving time and labor costs.

[0044] 2. By using the energy-absorbing structure 4 formed by the filling component, the energy-absorbing structure 4 can be flexible and versatile, and has strong applicability. It can be applicable to steel coils 5 of different specifications, and there is no need to modify the freight vehicle, nor to connect the steel coil 5 to the body structure of the freight vehicle, thereby avoiding damage to the body of the freight vehicle. At the same time, the materials of the energy-absorbing structure 4 and the filling component are cheap and easy to obtain, and the implementation plan is simple and popular, without the need for complex processing and manufacturing processes and strict personnel configuration requirements.

[0045] 3. By using the flexible connector 3 to pull the steel coil 5 onto the energy absorbing structure 4, additional friction is introduced, thereby reducing or limiting the accidental inertial movement of the steel coil 5 during transportation. The energy absorbing structure 4 close to the side of the cab 2 can serve as a buffer barrier to further protect the personal safety of the transportation personnel.

[0046] 4. By dispersing and setting up multiple energy-absorbing structures 4, compared with the traditional mechanical restriction scheme, it can disperse and flatten the stress distribution of the cargo platform 1, and avoid accidents such as overturning, tipping over, and bending of the cargo platform 1 during transportation.
