Technical Field

[0001] This application belongs to the field of steel coil transportation technology, specifically relating to a steel coil transportation device. Background Technology

[0002] In the steel coil production process, the traditional method for transferring steel coils between different factory spans (workshops) is to use overhead cranes and cross-span transport vehicles. The overhead cranes lift the steel coils onto the cross-span transport vehicles, which then move them to another span. Finally, the overhead cranes on the other span lift the steel coils from the cross-span transport vehicles to the designated location.

[0003] This method requires multiple lifting operations using an overhead crane, which can easily cause the steel coils to bump and scrape during the lifting process, affecting their quality. Summary of the Invention

The clearance opening is located on one side of the vehicle body along its width direction and extends through the vehicle body along its height direction. The support structure includes two support members located on both sides of the clearance opening along the length direction of the vehicle body. The cut is used to allow the steel coil trolley to pass along the width of the vehicle body, and the clearance is used to allow the steel coil trolley to pass. The cut and the clearance are located on the same side of the transport vehicle.

[0006] In some embodiments, the size of the clearance is equal to the size of the break along the length of the transport vehicle.

[0007] In some embodiments, multiple clearance openings are provided, and the multiple clearance openings are distributed at intervals along the length direction of the vehicle body; the number of support structures is the same as the number of clearance openings, and they are arranged in a one-to-one correspondence.

[0008] In some embodiments, the number of breaks in the unloading workshop and the number of breaks in the loading workshop are the same as the number of clearance openings and correspond one-to-one. When the transport vehicle travels to the loading position, multiple breaks in the loading workshop correspond to the corresponding clearance opening positions. When the transport vehicle travels to the unloading position, multiple breaks in the unloading workshop correspond to the corresponding clearance opening positions.

Detailed Implementation

[0025] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] The first aspect of this application provides a steel coil transport device with high transport efficiency.

[0027] This application is described below with reference to the accompanying drawings and specific embodiments: Please see Figures 1 to 4 The steel coil 500 transport device provided in this application embodiment includes a transport track 100 and a transport vehicle 200. The two ends of the transport track 100 are located in the unloading workshop and the loading workshop, respectively. The transport track 100 includes a first track 110 and a second track 120, which are arranged opposite to each other. The first track 110 has a broken end 111, and both the unloading workshop and the loading workshop have broken ends 111. The transport vehicle 200 includes a vehicle body 210 that travels on the transport track 100. The vehicle body 210 has a clearance opening 211 for the steel coil trolley to pass through and a support structure 280 for supporting the steel coil 500. The clearance opening 211 is located on one side of the vehicle body 210 along its width direction and extends along the height direction of the vehicle body 210. The support structure 280 includes two support members 281 located on both sides of the clearance opening 211 along the length direction of the vehicle body 210. The broken end 111 and the clearance opening 211 are located on the same side of the transport vehicle 200.

[0028] The transport track 100 provides a running track for the transport vehicle 200, improving the stability of the transport vehicle 200 during operation. The first track 110 has a break 111 for the passage of the steel coil trolley. This allows the steel coil 500 to be transferred from the loading workshop to the support structure 280 via the steel coil trolley without the need for overhead crane. After being transported to the unloading workshop, the steel coil 500 can be unloaded from the transport vehicle 200 via the steel coil trolley. The entire process does not require the intervention of an overhead crane, reducing the risk of collisions to the steel coil 500 and improving its quality.

[0029] The support member 281 is located on both sides of the clearance opening 211 along the length of the vehicle body 210. Therefore, the steel coil 500 is supported by the two support members 281 at the same time. The axial direction of the steel coil 500 is the same as the conveying direction. It is suitable for scenarios where the production line and workshop layout are perpendicular to each other. In other words, it is suitable for scenarios where the extension direction of the production line is perpendicular to the transportation direction.

[0030] The break 111 and the clearance 211 are located on the same side of the transport vehicle 200. During the coiling process, the steel coil trolley carries the steel coil 500 along the width direction of the transport vehicle 200. The steel coil trolley passes through the break 111 in the coiling workshop and moves into the clearance 211, so that the steel coil 500 of the steel coil trolley is directly above the clearance 211. As the saddle of the steel coil trolley descends, the steel coil 500 also descends and switches to be supported by the support structure 280 of the transport vehicle 200. Then the saddle of the steel coil trolley is lowered to below the body 210 of the transport vehicle 200. The steel coil trolley then returns along the width direction of the transport vehicle 200, leaves the transport vehicle 200, and completes the transfer of the steel coil 500 to the transport vehicle 200.

[0031] Uncoiling is the reverse process of coiling. The coil trolley runs along the width of the transport vehicle 200, passes through the break 111 in the uncoiling workshop, and runs to the area directly below the clearance opening 211. The saddle of the coil trolley rises, so that the coil 500 is switched from being supported by the support structure 280 to being supported by the coil trolley. The saddle stops rising, and the coil trolley carries the coil 500 back along the width of the transport vehicle 200 until it leaves the transport vehicle 200, completing the transfer of the coil 500 to the coil trolley.

[0032] In some embodiments, the size of the clearance opening 211 along the length of the transport vehicle 200 can be equal to the size of the break 111, allowing the steel coil trolley to move freely within the break 111. In other words, the steel coil trolley can move freely within the clearance opening 211, thus enabling it to move freely within the break 111. Having the clearance opening 211 and the break 111 of the same size maximizes space utilization. In other embodiments, the size of the clearance opening 211 along the length of the transport vehicle 200 can be smaller than the size of the break 111. This means the break 111 is relatively large along the length of the transport vehicle 200, still allowing for the transport of the steel coil 500, but potentially increasing the instability of the transport vehicle 200's operation to some extent. In some other embodiments, the size of the clearance opening 211 along the length of the transport vehicle 200 can also be larger than the size of the break 111. That is to say, the size of the clearance opening 211 along the length of the transport vehicle 200 is relatively large, and the transport of the steel coil 500 can still be realized. However, it should be noted that the support structure 280 should be able to stably support the steel coil 500, and the size of the suspended part of the steel coil 500 should not be too large.

[0033] In some embodiments, please refer to Figure 5 Multiple clearance openings 211 are provided, such as two, three, or four, and these clearance openings 211 are spaced apart along the length of the vehicle body 210. The multiple clearance openings 211 allow for the transport of multiple steel coils 500, increasing the transport capacity of the transport device and ensuring transport efficiency. In other embodiments, only one clearance opening 211 may be provided, resulting in a smaller transport vehicle 200 and higher transport stability.

[0034] Please see Figure 6 When multiple clearance openings 211 are provided, multiple support structures 280 are also provided. The number of support structures 280 is the same as the number of clearance openings 211. Multiple support structures 280 are arranged sequentially along the length direction of the vehicle body 210. The clearance openings 211 and support structures 280 are arranged one-to-one. The two support members 281 of the support structure 280 are located on both sides of the corresponding clearance opening 211 along the length direction of the vehicle body 210, thereby realizing the support of multiple steel coils 500.

[0035] Please see Figure 2The support member 281 may have an upward-facing positioning groove 2811, which is aligned with a corresponding clearance opening 211 to improve the stability of the steel coil 500 during the support process. The support member 281 can be connected to the vehicle body 210 by bolts. The clearance opening 211 can be rectangular or arc-shaped; this application does not impose any limitation. The support member 281 can be made of materials such as nylon or polyurethane to protect the surface of the steel coil 500. Alternatively, a nylon or polyurethane layer can be applied to the surface of the support member 281 to further protect the surface of the steel coil 500.

[0036] The vehicle body 210 can be welded from structural steel and steel plates, thus making use of on-site steel materials.

[0037] In some embodiments, the number of breaks 111 in the unwinding workshop and the number of breaks 111 in the winding workshop are the same as the number of clearance openings 211 and correspond one-to-one. When the transport vehicle 200 moves to the winding position, the multiple breaks 111 in the winding workshop correspond to the positions of the corresponding clearance openings 211. When the transport vehicle 200 moves to the unwinding position, the multiple breaks 111 in the unwinding workshop correspond to the positions of the corresponding clearance openings 211. In this way, multiple steel coil trolleys can be set up to perform simultaneous winding and unwinding operations on multiple steel coils 500.

[0038] Please see Figure 4 The transport vehicle 200 includes support wheels 230 and wheel sets 220, both mounted on the vehicle body 210. The support wheels 230 and the clearance opening 211 are located on the same side of the vehicle body 210. There are two support wheels 230, located on opposite sides of the clearance opening 211 along the length of the vehicle body 210. There are multiple wheel sets 220, arranged sequentially along the length of the vehicle body. Each wheel set 220 is located between two support wheels 230, meaning the two support wheels 230 are on the outermost side. The clearance opening 211 and the wheel sets 220 are located between the two support wheels 230. Along the length of the vehicle body 210, the distance between the support wheel 230 and the adjacent wheel set 220 is greater than the break 111. The support wheel 230 and the wheel set 220 can provide support for the vehicle body 210. The support wheel 230 is located on the side of the clearance opening 211 of the vehicle body 210, so the number of wheels on the side of the clearance opening 211 of the vehicle body 210 is more than the number of wheels on the side of the non-clearance opening 211. Moreover, the distance between the support wheel 230 and the wheel set 220 is greater than the break 111. This means that when one of the support wheel 230 or the adjacent wheel set 220 is suspended at the break 111, the other can contact the track for support, thereby ensuring the stability of the transport vehicle 200 during operation, and also reducing the number of wheels and reducing costs.

[0039] In other embodiments, the transport vehicle 200 may also include only wheel sets 220. Multiple wheel sets 220 are provided and arranged sequentially along the length of the vehicle body 210. As long as there are enough wheel sets 220, even if two wheel sets 220 are suspended in the air at the same time, the stability of the transport vehicle 200 during operation can still be guaranteed.

[0040] Please see Figure 4 When multiple clearance openings 211 are provided, a wheel set 220 is provided between any two adjacent clearance openings 211. The distance between the support wheel 230 and the adjacent wheel set 220 along the length of the vehicle body 210 is less than the distance between two adjacent clearance openings 211. Here, the distance between two adjacent clearance openings 211 refers to the distance between the edges of the two clearance openings 211 that are close to each other. The fact that the distance between the support wheel 230 and the adjacent wheel set 220 along the length of the vehicle body 210 is less than the distance between any two adjacent clearance openings 211 means that the distance between the support wheel 230 and the adjacent wheel set 220 along the length of the vehicle body 210 is less than the distance between any two adjacent breaks 111 in the unloading workshop or the loading workshop. In this way, at least one of the support wheel 230 and the adjacent wheel set 220 will be in contact with and supported by the first track 110, and they will not be suspended in the air at the same time. This further improves the stability of the transport vehicle 200 during operation and also saves costs.

[0041] In other embodiments, the distance between the support wheel 230 and the adjacent wheel set 220 along the length of the vehicle body 210 can also be greater than the distance between two adjacent clearance openings 211. In this case, more wheel sets 220 need to be set to increase the density of the wheel sets 220. Even if the support wheel 230 and the adjacent wheel set 220 are suspended in the air at the same time, there are still many other wheel sets 220 to support it, ensuring the stability of the transport vehicle 200 during operation.

[0042] Please see Figure 4 The transport vehicle 200 includes a drive assembly 240, which includes a drive member 241. The drive member 241 has a rotatable output end, which is connected to at least one wheel assembly 220 for transmission, thereby enabling the rotation of the wheel assembly 220 and driving the transport vehicle 200. The wheel assembly 220 is driven by the drive member 241, acting as the drive wheel to provide forward power for the transport vehicle 200. The support wheels 230 do not require power and only provide a supporting function, reducing energy consumption and ensuring stability during transportation.

[0043] In some embodiments, please refer to Figure 4The drive assembly 240 also includes a transmission chain 242, the output end of which is connected to the drive shaft 222 of the wheel assembly 220. The wheel assembly 220 is provided with a sprocket 223 coaxial with the drive shaft 222. The transmission chain 242 meshes with the sprockets 223 of at least two wheel assemblies 220, thereby realizing the rotation of the wheel assembly 220 and driving the transport vehicle 200. In some embodiments, the sprocket 223 can be replaced with a roller, and the transmission chain 242 can be replaced with a belt. The belt and roller cooperate to realize the rotation of the wheel assembly 220 and drive the transport vehicle 200.

[0044] When a chain is used, the drive assembly 240 also includes a tension sprocket 243 mounted on the vehicle body 210 to tension the chain and prevent the chain from dragging on the ground and affecting the transmission effect.

[0045] Please see Figure 4 The wheel assembly 220 may include wheels 221 and a drive shaft 222. There are two wheels 221, which are respectively connected to the two ends of the drive shaft 222. The two wheels 221 are located on both sides of the width direction of the vehicle body 210, thereby stably driving the transport vehicle 200 to run.

[0046] In some embodiments, please refer to Figure 4 There are two clearance openings 211 and four wheel sets 220. The four wheel sets 220 are arranged sequentially along the length of the vehicle body 210 as a first wheel set, a second wheel set, a third wheel set, and a fourth wheel set. The second and third wheel sets are located between the two clearance openings 211, while the first and fourth wheel sets are located on the outside of the two clearance openings 211. There are two drive units 241, which are respectively connected to the drive shafts 222 of the second and third wheel sets. The sprockets 223 of the first and second wheel sets are connected by chain drive, as are the sprockets 223 of the third and fourth wheel sets. The arrangement of four wheel sets 220 and two clearance openings 211 improves the conveying capacity of the steel coil 500 while preventing excessive weight and improving stability during transportation.

[0047] It is important to note that the contact point between wheel 221 and drive shaft 222 needs to be isolated with insulating material to prevent the vehicle body 210 from becoming electrified and to improve safety.

[0048] Please see Figure 7 and Figure 8The transport vehicle 200 includes a power pickup assembly 250, a fixed bracket 251, an adjusting bracket 252, and a power pickup plate 254. The fixed bracket 251 is connected to the vehicle body 210, the adjusting bracket 252 is height-adjustably connected to the fixed bracket 251, and the power pickup plate 254 is installed on the adjusting bracket 252 and is in contact with the second track 120.

[0049] The track can be powered by 36V. The contact plate 254 is positioned in contact with the track, transmitting electricity from the track to the booster cabinet 260 of the transport vehicle 200. This converts the 36V power into the voltage required for the drive unit 241, i.e., the motor. This eliminates the need for a battery on the transport vehicle 200 and for dragging cables, making it more convenient. The adjustable bracket 252 means the height of the contact plate 254 is also adjustable, accommodating different heights of the second track 120 and ensuring good contact between them. The contact plate 254 can be made of metal, such as copper or aluminum.

[0050] In other embodiments, a battery may be provided on the transport vehicle 200 to provide power to the drive unit 241, enabling the drive unit 241 to operate.

[0051] In some embodiments, please refer to Figure 7 and Figure 8 The fixed bracket 251 is provided with an oblong hole 2511 extending along the height direction, and the adjusting bracket 252 is provided with a round hole. The contactor assembly 250 also includes a threaded connector connecting the fixed bracket 251 and the adjusting bracket 252, with the threaded connector's screw extending into the oblong hole 2511 and the round hole. When it is necessary to adjust the height of the contactor 254, the nut of the threaded connector is loosened, the height of the bracket 252 is adjusted, and after the height is determined, the nut is tightened to fix the adjusting bracket 252 and the fixed bracket 251. In some embodiments, the adjusting bracket 252 is provided with an oblong hole 2511, and the fixed bracket 251 is provided with a round hole, which can also realize the height adjustment and locking of the adjusting bracket 252. Multiple oblong holes 2511 and round holes can be provided, such as two or three, which can improve the installation stability of the contactor 254.

[0052] In some embodiments, please refer to Figure 7 and Figure 8 The current pickup assembly 250 includes an insulating plate 253, which is located between the current pickup plate 254 and the adjusting bracket 252. The insulating plate 253 prevents the adjusting bracket 252 from becoming energized, thus improving safety.

[0053] In practical implementation, the insulating plate 253 can be made of nylon, rubber, ceramic, or plastic. The pickup plate 254, the insulating plate 253, and the adjusting bracket 252 are all provided with connecting holes. Bolts are inserted through these connecting holes, and nuts are connected to the bolts, thus fixing the pickup plate 254 and the insulating plate 253.

[0054] In some embodiments, a nylon washer may be provided between the nut and the adjusting bracket 252. The nylon washer passes through the bolt thread, and the diameter of the connecting hole of the insulating plate 253 is smaller than the diameter of the connecting hole of the adjusting bracket 252. This can prevent current from being transmitted to the adjusting bracket 252 through the bolt.

[0055] Please refer to the figure. Figure 6 The booster cabinet 260 and control cabinet 270 are installed on the body 210 of the transport vehicle 200. The booster cabinet 260 and control cabinet 270 can be located at the end of the body 210 along its own length direction and do not interfere with each other with the steel coil 500.

[0056] The booster switch 260 converts the low-voltage power picked up by the power pickup assembly 250 into the voltage required by the drive unit 241 and the control cabinet 270, ensuring electrical safety while meeting the voltage requirements of the drive unit 241 and the control cabinet 270. The control cabinet 270 contains a controller that can be electrically connected to the drive unit 241, energizing it as needed.

[0057] A protective railing can be installed on the vehicle body 210, with the booster cabinet 260 and control cabinet 270 located inside the protective railing to protect the booster cabinet 260 and control cabinet 270.

[0058] The 500 steel coil transport device also includes a positioning assembly (not shown in the figure), please refer to [link / reference]. Figure 1 and Figure 2 The positioning component includes a positioning reference 301 and a distance sensor 302 installed on the vehicle body 210. The distance sensor 302 is electrically connected to the controller. The positioning reference 301 can be installed on the ground. There can be two positioning references 301, one in the unloading workshop and the other in the loading workshop. The distance sensor 302 can measure the distance from itself to the positioning reference 301. When the transport vehicle 200 moves the distance sensor 302 closer to the loading or unloading position, the controller receives the distance detected by the distance sensor 302 from the positioning reference 301 of the loading or unloading position. When the distance is lower than a set value, the controller controls the drive component 241 to slow down, thereby decelerating the transport vehicle 200 and ensuring that the avoidance opening 211 stops stably at the position corresponding to the break opening 111.

[0059] In some embodiments, the positioning reference 301 can be a positioning plate or a positioning bracket, etc., and the installation position can be adjusted automatically according to the deceleration distance or acceleration distance, which is not limited in this application. The distance sensor 302 can be a laser rangefinder or a laser sensor, etc.

[0060] The positioning assembly also includes a sensor plate 305, a first proximity switch 303, and a second proximity switch 304. The sensor plate 305 is installed on the ground. Two sensor plates 305 can be installed, one in the unloading workshop and the other in the loading workshop. The sensor plate 305 includes a first sensing part and a second sensing part. The first proximity switch 303 and the second proximity switch 304 are both installed on the vehicle body 210. When the first proximity switch 303 senses the first sensing part, the controller receives the sensing signal from the first proximity switch 303. The controller considers that the transport vehicle 200 is about to reach the loading or unloading position and controls the drive unit 241 to decelerate. When the second proximity switch 304 senses the second sensing part, the controller simultaneously receives the sensing signals from the first proximity switch 303 and the second proximity switch 304. The controller considers that the transport vehicle 200 has reached the loading or unloading position and controls the drive unit 241 to stop working. The transport vehicle 200 stops, and at this time, the clearance opening 211 and the break opening 111 are exactly aligned, and the loading or unloading operation can be carried out.

[0061] Please see Figure 2 The sensing plate 305 can be configured as an L-shaped sensing plate 305. The first sensing part is a first sensing strip 3051, which extends along the length direction of the vehicle body 210. The second sensing part is a second sensing strip 3052, which extends along the width direction of the vehicle body 210. The first sensing strip 3051 and the second sensing strip 3052 are connected and perpendicular to each other. The first proximity switch 303 and the second proximity switch 304 are arranged sequentially along the width direction of the vehicle body 210.

[0062] During the operation of the transport vehicle 200, the vehicle body 210 first approaches the first sensing strip 3051. The first proximity switch 303 senses the first sensing strip 3051 first. Since the first sensing strip 3051 extends along the length of the vehicle body 210, the first proximity switch 303 can continuously emit sensing signals during the operation of the vehicle body 210. The controller can continuously receive the sensing signals emitted by the first proximity switch 303 and determine that the vehicle is about to reach the upper or lower winding position, and control the drive unit 241 to decelerate. When the vehicle body 210 moves close to the second sensing strip 3052, the second proximity switch 304 senses the second sensing strip 3052. At this time, the controller simultaneously receives the sensing signals emitted by the first proximity switch 303 and the second proximity switch 304, determines that the upper or lower winding position has been reached, and controls the drive unit 241 to stop operating.

[0063] In practical implementation, a distance less than a set value detected by distance sensor 302 serves as a signal for the vehicle body 210 to decelerate once. A signal from the first proximity switch 303 sensing the first sensing strip 3051 serves as a signal for the vehicle body 210 to decelerate a second time. A signal from the second proximity switch 304 sensing the second sensing strip 3052 serves as a signal for the vehicle body 210 to stop. This gradual deceleration and stopping of the vehicle body 210 improves transport stability and ensures more accurate parking. Conversely, during the process of the transport vehicle 200 leaving the upper or lower coil position, the controller first activates the drive unit 241, causing the transport vehicle 200 to accelerate. If the controller no longer receives sensing signals from the first and second proximity switches 303 and 304, it activates the drive unit 241 for a second acceleration. If the distance detected by distance sensor 302 is not less than the set value, the controller activates the drive unit 241 for a third acceleration to the normal transport speed, thus achieving the transfer of the steel coil 500.

[0064] With multiple clearance openings 211 and one break opening 111 in both the unloading and loading workshops, the number of sensor plates 305 at the loading or unloading positions can be the same as the number of clearance openings 211. Multiple sensor plates 305 are arranged sequentially at intervals along the length of the vehicle body 210, corresponding one-to-one with the multiple clearance openings 211. For clarity, taking the loading workshop as an example, there are two clearance openings 211 and two sensor plates 305 in the loading workshop. Please refer to [link to relevant documentation]. Figure 1 Two clearance openings 211, namely the first clearance opening 211a and the second clearance opening 211b, are arranged sequentially along the first direction. Two sensing plates 305, namely the first sensing plate 305 and the second sensing plate 305, are arranged sequentially along the second direction. The first and second directions are opposite. The transport vehicle 200 transports along the second direction. The first proximity switch 303 and the second proximity switch 304 first sense the first sensing plate 305, so that the first clearance opening 211a aligns with the break 111, and the winding begins. Then the transport vehicle 200 continues to move along the second direction, and the first proximity switch 303 and the second proximity switch 304 then sense the second sensing plate 305, so that the second clearance opening 211b aligns with the break 111, and the winding begins. The unwinding process in the unloading workshop is the same as described above, and will not be repeated in this application.

[0065] In some embodiments, the positioning component may further include a pressure sensor for detecting the presence of the steel coil 500 on the support structure 280, the pressure sensor being electrically connected to a controller. When the steel coil 500 is placed on the support structure 280, the pressure sensor transmits a pressure signal to the controller, which then determines that the support structure 280 contains the steel coil 500. When the steel coil 500 is removed by the steel coil trolley, the pressure sensor transmits no pressure signal to the controller, which then determines that the support structure 280 does not contain the steel coil 500.

[0066] With one break point 111 in the unloading workshop, one break point 111 in the loading workshop, and two clearance points 211, taking the loading workshop as an example, please refer to [link to relevant documentation]. Figure 1 The transportation process of the steel coil 500 transport device is as follows: The transport vehicle 200 arrives at the coiling position in the coiling workshop, where the clearance 211 corresponds to the break 111. The steel coil trolley then moves through the break 111 to the clearance 211. At this point, the height of the steel coil 500 is higher than the support structure 280. The lifting saddle of the steel coil trolley is located in the clearance 211. The lifting saddle of the steel coil trolley descends, and the support of the steel coil 500 changes from the lifting saddle to the support structure 280. The steel coil trolley then detaches from the steel coil 500 and retreats off the track, completing the coiling operation at the first clearance 211. The transport vehicle 200 continues to move a certain distance until the second clearance 211 corresponds to the break 111. The above actions are repeated to complete the coiling operation at the second clearance 211. The transport vehicle 200 then transports the two steel coils 500 to the unloading position in the unloading workshop for unloading.

[0067] With two break points 111 in the unloading workshop, two break points 111 in the loading workshop, and two clearance points 211, taking the loading workshop as an example, the transportation process of the steel coil 500 transport device is as follows: The transport vehicle 200 arrives at the loading position in the loading workshop, where the two clearance points 211 correspond one-to-one with the two break points 111. The two steel coil trolleys then travel through their respective break points 111 to the clearance points 211. At this point, the height of the steel coil 500 is higher than the support structure 280. The lifting saddle of the steel coil trolley is located in the clearance point 211. The lifting saddle of the steel coil trolley descends, and the support of the steel coil 500 changes from the lifting saddle to the support structure 280. The steel coil trolley disengages from the steel coil 500 and retreats off the track, completing the loading at the two clearance points 211. The transport vehicle 200 then transports the two steel coils 500 to the unloading position in the unloading workshop for unloading.

[0068] The steel coil 500 transport device provided in this application has at least the following advantages: (1) The car body 210 is equipped with multiple coil positions, which can improve the transportation efficiency of the transport vehicle 200. The car body 210 is provided with a clearance opening 211, and the first track 110 is provided with a break 111. This makes it convenient for the steel coil trolley to load or unload coils onto the transport vehicle 200 without the need for an overhead crane, which not only protects the surface quality of the steel coil 500, but also makes it more convenient.

[0069] (2) The support wheel 230 is only set on the side of the clearance opening 211, which reduces the cost of equipment processing and manufacturing. The distance between the support wheel 230 and the adjacent wheel set 220 is greater than the length of the break 111 and less than the distance between the two adjacent clearance openings 211, so that only one wheel is suspended in the air during transportation, and the vehicle body 210 is subjected to uniform force, thereby improving the stability of the steel coil 500 during transportation.

[0070] (3) Setting up positioning components enables automatic loading and transportation of steel coils, resulting in a high degree of automation.
