[0002] In the field of steel production, the transportation of steel coil products is a key link. Traditional transportation methods mostly rely on automobile transportation, which is not only inefficient but also has many safety hazards, especially in complex terrain conditions such as mountainous areas, where the road slope is large and the transportation risk is higher. In addition, automobile transportation will also produce exhaust pollution and increase labor costs.

[0003] A steel rolling project is located in a mountainous area. The hot rolling workshop and the hot acid annealing workshop are far apart in plan layout. The height difference of the construction site is large, with a height difference of 17.8m between the two workshops. The steel coil products of the two workshops are transported by car, and the transportation volume is relatively small, resulting in frequent transportation and low efficiency, which cannot meet the needs of large-scale production. In complex terrains such as mountainous areas, car transportation is prone to accidents due to the large road slope, which poses serious safety hazards. Once an accident occurs, it may cause the car to be destroyed and people to die. Cars use diesel, and exhaust emissions pollute the environment, which does not meet the production requirements of green environmental protection. Summary of the invention

[0030] Example 1

[0031] In order to improve transportation efficiency, reduce safety accidents, save energy and protect the environment, reduce product production costs, and realize intelligent, green and safe transportation methods for steel enterprises, this embodiment proposes a steel coil transportation system based on a battery locomotive 17, which is of great significance for improving production efficiency, reducing production costs, and realizing green production of steel enterprises.

[0032] This transportation system is not only suitable for the transportation of steel coils, but also for the transportation of all steel and long products, including commonly used I-beams, channel steels, angle steels, H-beams, as well as steel products with complex cross-sections such as rails, steel sheet piles, and B-beams, as well as round steel products such as bars. It is not only suitable for iron and steel type steel and long products, but also for non-ferrous type steel and long products.

[0033] like Figure 1 , Figure 2 As shown, the transport system is used to transport steel coils between the first workshop (hot acid annealing workshop) and the second workshop (hot rolling workshop), wherein the height of the second workshop is higher than that of the first workshop. The first workshop has a loading and unloading area, and the lower side of the second workshop has a deep pit area 13, the deep pit area 13 and the loading and unloading area are located at the same level, the loading and unloading area and the deep pit area 13 are connected by a railway track 7, and both the loading and unloading area and the deep pit area 13 are provided with a lifting device; there is a transport device on the railway track 7, the transport device includes a battery locomotive 17 and a flatbed car 18, the battery locomotive 17 drives the flatbed car 18 to move on the railway track 7; a charging room 4 is provided on one side of the railway track 7, the charging room 4 is connected to the railway track 7 through a side track, and an automatic single-opening turnout 5 is provided at the connection.

[0034] The steel coil transportation system of this embodiment is used to connect two workshops with a large height difference. The second workshop is higher than the first workshop. The first workshop has a loading and unloading area. The deep pit area 13 below the second workshop is connected to the loading and unloading area of ​​the first workshop through the railway track 7, and a lifting device is installed on the railway track 7 between the two areas. The lifting device can adopt existing technology, such as a crane, a gantry crane, etc. These lifting devices are responsible for loading the steel coils onto the flatbed truck 18 and unloading the steel coils from the flatbed truck 18, realizing the intelligent transportation of steel coils between the two workshops and solving the safety problems caused by the height difference between the two workshops. The battery locomotive 17 serves as a driving device, which can drive the flatbed truck 18 on the railway track 7 to ensure that the steel coils are smoothly and safely transported to the next workshop, achieving a green, environmentally friendly, safe and intelligent transportation effect.

[0035] The railway track 7 in the loading and unloading area of ​​the first workshop is provided with two loading and unloading lines 1, and an automatic single-opening turnout 5 is provided at the intersection of the two loading and unloading lines 1. Through the configuration of the automatic single-opening turnout 5, the direction of the railway track 7 can be flexibly adjusted to ensure that the flatbed truck 18 for each steel coil transportation can enter the designated loading and unloading line 1 for efficient loading and unloading. The automatic control of the turnout improves the intelligence of the system, reduces manual intervention, and ensures the reliability and efficiency of transportation.

[0036] The loading and unloading area of ​​the first workshop and the deep pit area 13 of the second workshop are both provided with a limit device and a safety guardrail 2, wherein the limit device includes a concrete vehicle stop 3. The concrete vehicle stop 3 effectively prevents the flatbed truck 18 from exceeding the predetermined track range due to improper operation or other accidents, thereby ensuring stability and safety during transportation. The guardrail plays a protective role, preventing personnel from accidentally entering the dangerous area, further improving the safety of the system.

[0037] like Figure 4 As shown, at least two flatbed trucks 18 are provided, and the battery locomotive 17 and the flatbed truck 18, as well as the flatbed trucks 18 and the flatbed trucks 18 are connected by automatic couplers 19. The flatbed trucks 18 are connected by the automatic couplers 19, and the battery locomotive 17 can tow one or more flatbed trucks 18. The design of the automatic couplers 19 makes the connection and disassembly between the flatbed trucks 18 easier and more efficient. The automatic couplers 19 are usually realized by a snap-on or mechanical hook design to ensure a stable connection and easy disassembly. Through this connection method, the battery locomotive 17 can tow multiple flatbed trucks 18 during transportation, thereby improving transportation capacity and efficiency.

[0038] Each flatbed car 18 is equipped with a carriage 14 suitable for loading steel coils. Figure 3 As shown, the size and structure of the carriage 14 should be optimized according to the shape and weight of the steel coil. The bottom of the carriage 14 can be equipped with a special tray or support device to ensure that the steel coil does not slide or tilt during transportation, thereby ensuring the stability of transportation.

[0039] The charging room 4 is located at one end of the railway track 7, near the first workshop. When the battery locomotive 17 is in transit and the battery is low in power, it will automatically drive into the charging room 4 for charging. The design of the charging room 4 ensures that the battery locomotive 17 can quickly connect to the power supply and perform charging operations when it stops.

[0040] like Figure 2 As shown, a gate 8 is arranged on the railway track 7 at one end of the first workshop, a slope 10 is arranged at one end of the second workshop, a road 11 is arranged on the slope 10, and the deep pit area 13 is located below the road 11. The railway track 7 includes an open section 9 and a closed section 12, the open section 9 is located between the first workshop and the slope 10, and the closed section 12 is located in the deep pit area 13. The configurations of the open section 9 and the closed section 12 correspond to different functional areas respectively. The setting of the open section 9 facilitates daily transportation operations, while the closed section 12 avoids interference of the external environment on the transportation process, thereby ensuring the stability and safety of the transportation system.

[0041] like Figure 3 As shown, a canopy 15 is provided on the open section 9 of the railway track 7, a pedestrian passage is provided on one side of the railway track 7, one side of the pedestrian passage is a safety guardrail 2, and the other side is a concrete wall 16, and a camera 6 is provided on the concrete wall 16.

[0042] The canopy 15 can prevent the impact of weather changes on the transportation process and protect operators and equipment from rain. The pedestrian walkway ensures that operators can perform monitoring and maintenance work in a safe area. The design of the canopy 15 and the pedestrian walkway improves the operability and safety of the system, especially in adverse weather conditions, ensuring that operators can work in a suitable environment. The design of the concrete wall 16 and the guardrail provides physical security, while the camera 6 on the wall is used to monitor the entire transportation process in real time, ensuring that operators can monitor the transportation status throughout the process. The camera 6 is connected to the monitoring system via the network, and the operator can view the transportation status in real time, ensuring the transparency and controllability of the transportation process.

[0043] After the battery locomotive 17 is charged, it enters the predetermined loading and unloading area through automatic control, and hoists the product onto the C70 flatbed truck 18 through the factory crane. After the hoisting is completed, the battery train is started through the automatic control system to transport the product to the next workshop. The hot acid annealing workshop has two loading and unloading lines 1, which can be controlled to enter different loading and unloading lines 1 through the automatic single-opening turnout 5. Then the battery locomotive 17 automatically stops at the predetermined loading and unloading area, and the product is unloaded from the C70 flatbed truck 18 to the designated location through the factory crane. The transportation of steel coil products is unmanned throughout the entire process.

[0044] Example 2

[0045] This embodiment proposes a transportation method using the steel coil transportation system based on the battery locomotive 17 as described in Embodiment 1, comprising:

[0046] 1. Transportation of steel coils

[0047] After the battery locomotive 17 is fully charged, it enters the transport line and is connected to two C70 flatbed trucks 18 (with carriages on the flatbed trucks 18) through the automatic coupler 19. The C70 flatbed truck 18 is towed into the deep pit area 13 of the hot rolling workshop, and the C70 flatbed truck 18 is parked at the designated position through the control system of the battery locomotive 17 and the railway limit device. After the battery locomotive 17 is parked, the signal is transmitted to the crane operator of the hot rolling workshop through wireless transmission. After receiving the signal, the crane operator enters the deep pit area 13 and hoists the steel coil onto the C70 flatbed truck 18. At the same time, the hoisting status of the battery locomotive 17 and the C70 flatbed truck 18 can also be monitored in real time through the monitoring screen in the crane room. Each roll of steel coil is about 30t, and each C70 flatbed truck 18 can load two rolls. After lifting the steel coils, the hot rolling crane operator transmits a signal to the automatic control system of the battery locomotive 17. The battery locomotive 17 pushes the C70 flatbed car 18 to the hot acid annealing workshop. The hot acid annealing workshop has two loading and unloading lines 1. The C70 flatbed car 18 is pushed to the designated loading and unloading line 1 through the automatic single-opening turnout 5. After the C70 flatbed car 18 stops at the designated position, the battery locomotive 17 transmits a wireless signal to the hot acid annealing crane operator, informing the hot acid annealing crane operator that the steel coils can be loaded and unloaded. After receiving the instruction, the hot acid annealing crane operator unloads the steel coils. After unloading is completed, the hot acid annealing crane operator transmits a signal to the battery locomotive 17. After receiving the signal, the battery locomotive 17 continues to tow the C70 flatbed car 18 to the hot rolling workshop for transporting the steel coils.

[0048] 2. Charging of battery locomotive 17

[0049] The battery locomotive 17 has 20% less power (20% of the power is enough to transport a steel coil) and is located in the loading and unloading area of ​​the hot acid stripping workshop, and automatically sends a signal to request charging. This signal is only sent to the crane operator in the hot acid stripping workshop. The hot acid stripping crane operator determines whether to allow this battery locomotive 17 to charge based on the charging status of another battery locomotive 17. If this battery locomotive 17 is allowed to charge, the control system enters the battery locomotive 17 interchange charging mode. Another battery locomotive 17 that has been charged starts to start and enters the predetermined track position through the automatic turnout. The battery locomotive 17 that needs to be charged is separated from the C70 flatbed car 18 through the automatic coupler 19, and then enters the predetermined charging position through the automatic turnout for charging. Then the signal is transmitted to another battery locomotive 17. After receiving the signal, the other battery locomotive 17 automatically starts and arrives at the hot acid stripping loading and unloading line 1, and is connected to the C70 flatbed car 18 through the automatic coupler 19. After the connection, the signal is transmitted to the hot acid assisted crane operator, and at the same time the control system changes the traction locomotive to the battery locomotive 17.

[0050] This transportation method uses an intelligent control system to achieve unmanned operation of the entire process, improving transportation efficiency, reducing labor costs, and ensuring the safety and reliability of transportation.

[0051] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
