[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figures 1 to 4 shown, the present invention provides a steel coil transportation system, including a multi-stage conveyor group 100 and at least one stage of lifting machine group 200. At least one stage of lifting machine group 200 is arranged between two adjacent stages of conveyor groups 100. Each stage of conveyor group 100 includes at least one heavy-load transportation path 110 and at least one light-load transportation path 120 arranged in parallel side by side.

At least one heavy-load transportation path 110 of each stage of conveyor group 100 and at least one heavy-load elevator 210 of the lifting machine group 200 are arranged in the same column to form a heavy-load conveyor line 10. At least one light-load transportation path 120 of each stage of conveyor group 100 and at least one light-load elevator 220 of the lifting machine group 200 are arranged in the same column to form a light-load conveyor line 20; along the steel coil transportation direction, transfer cross-moving vehicle groups 300 are arranged at both the diversion end and the converging end of the heavy-load conveyor line 10, and / or transfer cross-moving vehicle groups 300 are arranged at both the diversion end and the converging end of the light-load conveyor line 20.

[0041] Specifically, as Figures 1 to 4As shown in the figure, the steel coil transportation system includes multiple levels of conveying groups 100 and at least one level of lifting groups 200 arranged between adjacent levels of conveying groups 100. When there are multiple groups of lifting groups 200, along the steel coil conveying direction, the multiple levels of lifting groups 200 and the multiple levels of conveying groups 100 are arranged alternately, and the multiple levels of lifting groups 200 are arranged between the first-level conveying group 100 and the last-level conveying group 100. Among them, each level of conveying group 100 includes at least one heavy-load conveying path 110 arranged in parallel for conveying steel coils and at least one light-load conveying path 120 for conveying steel coil saddles. The lifting group 200 includes at least one heavy-load elevator 210 arranged side by side for transporting the steel coil to the height of the lower-level conveying group 100 in the steel coil conveying direction, and at least one light-load elevator 220 for transporting the steel coil saddle to the height of the lower-level conveying group 100 in the steel coil saddle conveying direction. The heavy-load elevator 210 is provided with a lifting heavy-load conveying path for carrying the steel coil, and this lifting heavy-load conveying path is only activated when the steel coil goes on and off the heavy-load elevator 210 to pick up and drop off the steel coil; similarly, the light-load elevator 220 is provided with a lifting light-load conveying path for carrying the steel coil saddle, and this lifting light-load conveying path is only activated when the steel coil saddle goes on and off the heavy-load elevator 210 to pick up and drop off the steel coil saddle. At least one heavy-load conveying path 110 of each level of conveying group 100 and at least one heavy-load elevator 210 of the lifting group 200 are arranged in the same column to form a heavy-load conveying line 10. At least one light-load conveying path 120 of each level of conveying group 100 and at least one light-load elevator 220 of the lifting group 200 are arranged in the same column to form a light-load conveying line 20. The heavy-load conveying line 10 is used to transport the steel coils produced by the rolling mill 1 to the finished product warehouse 2, and the light-load conveying line 20 is used to transport the steel coil saddles after the coils are unloaded in the finished product warehouse 2 to the side of the coiler 3 in the rolling mill 1 to wait for re-coiling. Among them, the heavy-load conveying paths 110 of each level of conveying group 100 and the heavy-load elevators 210 of the lifting group 200 located outside the heavy-load conveying line 10 and arranged in the same column are combined to form a heavy-load auxiliary conveying line 30. The starting end of the heavy-load auxiliary conveying line 30 is also the diversion end of the heavy-load conveying line 10, and the terminating end of the heavy-load auxiliary conveying line 30 is also the converging end of the heavy-load conveying line 10; similarly, the light-load conveying paths 120 of each level of conveying group 100 and the light-load elevators 220 of the lifting group 200 located outside the light-load conveying line 20 and arranged in the same column are combined to form a light-load auxiliary conveying line 40. The starting end of the light-load auxiliary conveying line 40 is also the diversion end of the light-load conveying line 20, and the terminating end of the light-load auxiliary conveying line 40 is also the converging end of the light-load conveying line 20.Along the steel coil conveying direction, transfer cross-traversing car groups 300 are provided at both the diverging end and the converging end of the heavy-load conveying line 10, and / or transfer cross-traversing car groups 300 are provided at both the diverging end and the converging end of the light-load conveying line 20, so as to facilitate the transfer of the steel coils on the heavy-load conveying line 10 to the heavy-load auxiliary conveying line 30 by means of the transfer cross-traversing car groups 300, and / or so as to facilitate the transfer of the steel coil saddles on the light-load conveying line 20 to the light-load auxiliary conveying line 40 by means of the transfer cross-traversing car groups 300, thereby ensuring the timely transfer of the incoming materials at the rear when the lifting unit 200 performs lifting and conveying, and achieving the purpose of making up for the gap between the lifting efficiency of the lifting unit 200 and the steel coil production efficiency through the reasonable diversion of the conveyed materials, so that the transport efficiency of the steel coil transport system matches the steel coil production efficiency.

[0042] Preferably, the conveying group 100 is one of a roller path group, a sliding contact track group, and a capacitor car track group. Correspondingly, the steel coil saddle is one of a tray roller path car saddle that cooperates with the roller path group, a sliding contact car saddle that cooperates with the sliding contact track group, and a capacitor car saddle that cooperates with the capacitor car track group. Of course, the conveying group 100 can also adopt other conveying methods to realize the steel coil conveying. Similarly, the conveying group 100 can also be a combination of several of the roller path group, the sliding contact track group, and the capacitor car group. The present invention does not limit this. In this embodiment, the conveying group 100 adopts the roller path conveying method.

[0043] Preferably, the lifting unit 200 is multi-stage. Along the steel coil conveying direction, the multi-stage lifting unit 200 is arranged between the first-stage conveying group 100 and the last-stage conveying group 100. Specifically, as Figures 1 to 4 shown, in order to realize the steel coil transportation in a site with a large height difference, the lifting unit 200 is set as multiple groups as required. Along the steel coil conveying direction, the multi-stage lifting unit 200 and the multi-stage conveying group 100 are arranged alternately, and the multi-stage lifting unit 200 is arranged between the first-stage conveying group 100 and the last-stage conveying group 100. In this way, the steel coil is transported across a large height difference through the lifting and conveying of the multi-stage lifting unit 200, avoiding the earthwork filling operation when building the rolling mill 1 and the finished product warehouse 2 in a site with a large height difference. For a rolling mill production enterprise with many mountains to build a factory, using the steel coil transport system provided by the present application has the advantages of saving time and effort and reducing construction costs.

[0044] Preferably, the lifting unit 200 includes a plurality of heavy-load elevators 210 arranged side by side. Among at least one of the two adjacent conveying groups 100 to the lifting unit 200, at least one conveying group 100 includes a plurality of heavy-load transport paths 110 arranged in one-to-one correspondence with the plurality of heavy-load elevators 210. Specifically, as Figures 1 to 4As shown in the figure, the lifting unit group 200 includes multiple heavy-duty elevators 210 arranged side by side. Along the steel coil conveying direction, the upper-level conveying group 100 adjacent to the lifting unit group 200 includes multiple heavy-duty conveying tracks 110 arranged in one-to-one correspondence with the multiple heavy-duty elevators 210. Or, the lower-level conveying group 100 adjacent to the lifting unit group 200 includes multiple heavy-duty conveying tracks 110 arranged in one-to-one correspondence with the multiple heavy-duty elevators 210. Or, both the upper-level conveying group 100 and the lower-level conveying group 100 adjacent to the lifting unit group 200 include multiple heavy-duty conveying tracks 110 arranged in one-to-one correspondence with the multiple heavy-duty elevators 210.

[0045] Furthermore, the lifting unit group 200 includes multiple light-duty elevators 220 arranged side by side. At least one of the two-level conveying groups 100 adjacent to the lifting unit group 200 includes multiple light-duty conveying tracks 120 arranged in one-to-one correspondence with the multiple light-duty elevators 220. Specifically, as Figures 1 to 4 shown in the figure, the lifting unit group 200 includes multiple light-duty elevators 220 arranged side by side. Along the steel coil saddle conveying direction, the upper-level conveying group 100 adjacent to the lifting unit group 200 includes multiple light-duty conveying tracks 120 arranged in one-to-one correspondence with the multiple light-duty elevators 220. Or, the lower-level conveying group 100 adjacent to the lifting unit group 200 includes multiple light-duty conveying tracks 120 arranged in one-to-one correspondence with the multiple light-duty elevators 220. Or, both the upper-level conveying group 100 and the lower-level conveying group 100 adjacent to the lifting unit group 200 include multiple light-duty conveying tracks 120 arranged in one-to-one correspondence with the multiple light-duty elevators 220.

[0046] Specifically, both the diverging end and the converging end of the heavy-duty conveying line 10 are arranged between the adjacent lifting unit group 200 and the conveying group 100. Or, both the diverging end and the converging end of the heavy-duty conveying line 10 are arranged between the adjacent conveying groups 100. Or, one of the diverging end and the converging end of the heavy-duty conveying line 10 is arranged between the adjacent lifting unit group 200 and the conveying group 100, and the other of the diverging end and the converging end of the heavy-duty conveying line 10 is arranged between the adjacent conveying groups 100. Specifically, as Figure 2 shown in the figure, both the diverging end and the converging end of the heavy-duty conveying line 10 are arranged between the adjacent lifting unit group 200 and the conveying group 100. In this case, along the steel coil conveying direction, the transfer traversing car group 300 is arranged at the upstream end of the front lifting unit group 200 and the downstream end of the rear lifting unit group 200. Or, as Figure 1 shown in the figure, both the diverging end and the converging end of the heavy-duty conveying line 10 are arranged between the adjacent conveying groups 100. In this case, along the steel coil conveying direction, the transfer traversing car group 300 is arranged between the two adjacent conveying groups 100 at the upstream end of the front lifting unit group 200 and between the two adjacent conveying groups 100 at the downstream end of the rear lifting unit group 200. Or, as Figure 3As shown in the figure, one of the diverging end and the converging end of the heavy-load conveyor line 10 is arranged between the adjacent lifting unit groups 200 and the conveying unit group 100, and the other of the diverging end and the converging end of the heavy-load conveyor line 10 is arranged between the adjacent conveying unit groups 100. In this case, along the steel coil conveying direction, the transfer traversing car group 300 is arranged between two adjacent conveying unit groups 100 at the upstream end of the front lifting unit group 200 and the downstream end of the rear lifting unit group 200, or the transfer traversing car group 300 is arranged between two adjacent conveying unit groups 100 at the upstream end of the front lifting unit group 200 and at the downstream end of the rear lifting unit group 200. Among them, if the heavy-load conveyor line 10 has only a diverging end but no converging end, that is, the heavy-load auxiliary conveyor line 30 directly extends to the finished product warehouse 2, only the transfer traversing car group 300 needs to be arranged at the starting end of the heavy-load auxiliary conveyor line 30.

[0047] Similarly, as Figure 2 shown in the figure, both the diverging end and the converging end of the light-load conveyor line 20 are arranged between the adjacent lifting unit groups 200 and the conveying unit group 100. In this case, along the steel coil saddle conveying direction, the transfer traversing car group 300 is arranged at the upstream end of the front lifting unit group 200 and the downstream end of the rear lifting unit group 200; or, as Figure 1 shown in the figure, both the diverging end and the converging end of the light-load conveyor line 20 are arranged between the adjacent conveying unit groups 100. In this case, along the steel coil saddle conveying direction, the transfer traversing car group 300 is arranged between two adjacent conveying unit groups 100 at the upstream end of the front lifting unit group 200 and between two adjacent conveying unit groups 100 at the downstream end of the rear lifting unit group 200; or, as Figure 3 shown in the figure, one of the diverging end and the converging end of the light-load conveyor line 20 is arranged between the adjacent lifting unit groups 200 and the conveying unit group 100, and the other of the diverging end and the converging end of the light-load conveyor line 20 is arranged between the adjacent conveying unit groups 100. In this case, along the steel coil saddle conveying direction, the transfer traversing car group 300 is arranged between two adjacent conveying unit groups 100 at the upstream end of the front lifting unit group 200 and the downstream end of the rear lifting unit group 200, or the transfer traversing car group 300 is arranged between two adjacent conveying unit groups 100 at the upstream end of the front lifting unit group 200 and at the downstream end of the rear lifting unit group 200. Among them, if the light-load conveyor line 20 has only a diverging end but no converging end, that is, the light-load auxiliary conveyor line 40 directly extends to the rolling mill 1, only the transfer traversing car group 300 needs to be arranged at the starting end of the light-load auxiliary conveyor line 40; if the light-load conveyor line 20 has only a converging end but no diverging end, that is, the light-load auxiliary conveyor line 40 directly leads out from the finished product warehouse 2, only the transfer traversing car group 300 needs to be arranged at the terminating end of the light-load auxiliary conveyor line 40.

[0048] In this embodiment, the heavy-load auxiliary conveying line 30 and the light-load auxiliary conveying line 40 are arranged side by side and aligned, that is, the starting end and the terminating end of the heavy-load auxiliary conveying line 30 are respectively arranged side by side with the terminating end and the starting end of the light-load auxiliary conveying line 40. In this way, the heavy-load auxiliary conveying line 30 and the light-load auxiliary conveying line 40 can share the same transfer traversing car group 300, thereby saving the number of arrangements of the transfer traversing car group 300. Of course, the heavy-load auxiliary conveying line 30 and the light-load auxiliary conveying line 40 can also be arranged side by side and staggered, and the present utility model does not limit this. Among them, when the lifting and conveying speed of the light-load elevator 220 in the elevator group 200 can match the lifting and conveying speeds of multiple heavy-load elevators 210, the steel coil transportation system can be provided with only the heavy-load auxiliary conveying line 30 without the need to provide the light-load auxiliary conveying line 40. Similarly, when the transportation efficiency of the heavy-load conveying line 10 can match the steel coil production efficiency of the steel rolling mill 1, only the heavy-load conveying line 10 can be provided without the need to provide the heavy-load auxiliary conveying line 30.

[0049] Specifically, as Figures 1 to 4 shown, the transfer traversing car group 300 includes a heavy-load traversing car 310 and a light-load traversing car 320 arranged side by side. The heavy-load traversing car 310 is arranged on one side of the heavy-load conveying line 10, and is provided with a heavy-load conveying path 110 thereon; the light-load traversing car 320 is arranged on one side of the light-load conveying line 20, and is provided with a light-load conveying path 120 thereon. In this way, the heavy-load traversing car 310 is used to carry the steel coil on the heavy-load conveying line 10 to the heavy-load auxiliary conveying line 30, and the light-load traversing car 320 is used to carry the steel coil saddle on the light-load conveying line 20 to the light-load auxiliary conveying line 40, so that the steel coil and the steel coil saddle can be carried to the heavy-load auxiliary conveying line 30 and the light-load auxiliary conveying line 40 respectively at the same time without interference, ensuring the relative independence of the diversion of the steel coil and the steel coil saddle. Among them, the heavy-load traversing car 310 is provided with a handling heavy-load conveying path for receiving and sending the steel coil, and the light-load traversing car 320 is provided with a handling light-load conveying path for receiving and sending the steel coil saddle.

[0050] Preferably, as Figures 1 to 4As shown, the steel coil transportation system further includes a first steel coil saddle traversing vehicle 400 and a second steel coil saddle traversing vehicle 500. Along the steel coil conveying direction, the first steel coil saddle traversing vehicle 400 and the second steel coil saddle traversing vehicle 500 are respectively arranged at the loading end of the primary conveying group 100 and the discharging end of the final conveying group 100. The first steel coil saddle traversing vehicle 400 arranged at the loading end of the primary conveying group 100 along the steel coil conveying direction transports the steel coil saddle from the light-load conveying path 120 of the primary conveying group 100 to the heavy-load conveying path 110 beside the coiler 3 in the rolling mill 1 transported back from the finished product warehouse 2. The second steel coil saddle traversing vehicle 500 arranged at the discharging end of the final conveying group 100 along the steel coil conveying direction transports the steel coil saddle after unloading the coil from the heavy-load conveying path 110 of the final conveying group 100 to the light-load conveying path 120. In this way, the automatic pipeline transportation of the steel coil is realized. Since the primary conveying group 100 and the final conveying group 100 are respectively arranged in the rolling mill 1 and the finished product warehouse 2, the transportation of the steel coil saddle between the heavy-load conveying path 110 and the light-load conveying path 120 can also be realized by other lifting equipment.

[0051] Furthermore, the steel coil transportation system further includes a turntable 600, and the turntable 600 is arranged at the direction-changing position of the steel coil conveying direction. Specifically, as Figures 1 to 4As shown in the figure, to achieve a turn in the conveying direction of the steel coil, the steel coil transportation system further includes a rotary table 600. The rotary table 600 is arranged between two conveying groups 100 with inconsistent conveying directions. On the rotary table 600, there are a rotary heavy-load conveying track for picking up and delivering the steel coil and a rotary light-load conveying track for picking up and delivering the steel coil saddle. When the steel coil is conveyed to the conveying group 100 at the upstream end of the rotary table 600, after the rotary table 600 rotates until the conveying direction of its rotary heavy-load conveying track is the same as that of the upper-level heavy-load conveying track 110, the rotary heavy-load conveying track on the rotary table 600 starts to pick up and transport the steel coil on the upper-level heavy-load conveying track 110. After the steel coil is picked up and transported, this rotary heavy-load conveying track shuts down. After the rotary table 600 rotates until the conveying direction of its rotary heavy-load conveying track is the same as that of the lower-level heavy-load conveying track 110, the rotary heavy-load conveying track on the rotary table 600 starts to transport the steel coil on it again. After the steel coil is transported to the lower-level heavy-load conveying track 110, this rotary heavy-load conveying track shuts down; similarly, when the steel coil saddle is conveyed to the conveying group 100 at the upstream end of the rotary table 600, after the rotary table 600 rotates until the conveying direction of its rotary light-load conveying track is the same as that of the upper-level light-load conveying track 120, the rotary light-load conveying track on the rotary table 600 starts to pick up and transport the steel coil on the upper-level light-load conveying track 120. After the steel coil is picked up and transported, this rotary light-load conveying track shuts down. After the rotary table 600 rotates until the conveying direction of its rotary light-load conveying track is the same as that of the lower-level light-load conveying track 120, the rotary light-load conveying track on the rotary table 600 starts to transport the steel coil on it again. After the steel coil is transported to the lower-level light-load conveying track 120, this rotary light-load conveying track shuts down. Among them, by controlling the material transportation interval time of the heavy-load conveying line 10 and the light-load conveying line 20, the interval commutation picking up and transporting of the steel coil and the steel coil saddle can be realized.

[0052] Furthermore, the steel coil transportation system further includes a steel coil tower-shaped repair device 700, a weighing device 800, and a printing device 900.

The steel coil tower-shaped repair device 700 quickly repairs the tower-shaped end face of the steel coil to improve the overall shape of the steel coil, so that the shaped steel coil has a more flat end face, which is more convenient for subsequent steel coil bundling operations; the weighing device 800 weighs the steel coil to obtain the weight data of each steel coil. Preferably, the weighing device 800 is a roller scale; the printing device 900 performs identification printing on the steel coil for management.

[0053] Preferably, along the steel coil conveying direction, the height of the first-stage conveying group 100 is greater than that of the last-stage conveying group 100, or the height of the first-stage conveying group 100 is less than that of the last-stage conveying group 100. Specifically, the steel coil transportation system provided by the present invention can be used for the transportation of steel coils with a large height difference from low to high between the low-position rolling mill 1 and the high-position finished product warehouse 2, or for the transportation of steel coils with a large height difference from high to low between the high-position rolling mill 1 and the low-position finished product warehouse 2.

[0054] Based on the above structural description, the steel coil transportation system provided by the present invention has the following beneficial effects:

[0055] The steel coil transportation system provided by the present invention includes multiple stages of conveying groups 100 and at least one stage of lifting groups 200. The at least one stage of lifting groups 200 is arranged between two adjacent stages of conveying groups 100. The number of lifting groups 200 can be adaptively configured according to the height difference between the rolling mill 1 and the finished product warehouse 2, so as to realize the transportation of steel coils in a site with a large height difference through multi-stage lifting. At the same time, the number of heavy-load conveying channels 110 and light-load conveying channels 120 of each stage of conveying group 100, and the number of heavy-load elevators 210 and light-load elevators 220 of each stage of lifting group 200 can also be adaptively configured according to the matching relationship between the production efficiency and transportation volume of the rolling mill 1, so as to realize the timely and rapid transportation of the steel coils produced by the rolling mill 1.
