[0002] At present, in the continuous heat treatment lines of silicon steel in the metallurgical industry, all of them pass through continuous annealing, recoiling and packaging units. Originally, a steel coil warehouse was set up between the continuous annealing unit and the recoiling and packaging units. A crane was needed to temporarily store the steel coils in the steel coil warehouse. Often, the continuous annealing unit and the recoiling unit are not in the same factory building, so two cranes are needed to transport the steel coils. One crane needs to be operated by one crane, which is very work-intensive. Utility Model Content

[0022] Reference Figure 1 In this preferred embodiment, a steel coil transportation system based on a mother-and-child car to realize heavy coil packaging logistics includes a walking beam 1, a first cross saddle 2, a second cross saddle 3, a third cross saddle 4, a first mother-and-child car transportation device 5 and a second mother-and-child car transportation device 6, wherein,

[0023] The first parent-child transport device 5 and the second parent-child transport device 6 each include a steel coil transport parent car, a steel coil transport child car, a parent car running track and at least one child car running main track, one end of the child car running main track is connected to the parent car running track;

[0024] One end of the mother car running track of the first mother car transport device 5 is arranged adjacent to the side of the first cross saddle 2, and the other end of the mother car running track of the first mother car transport device 5 is arranged adjacent to the side of the second cross saddle 3. The side of the first cross saddle 2 is also arranged adjacent to the walking beam 1, and the side of the second cross saddle 3 is also arranged adjacent to the first packaging unit 12 to form a first steel coil transport channel (the steel coil passes through the first mother car transport device 5, the second cross saddle 3 and the first packaging unit 12 in sequence to form the first steel coil transport channel);

[0025] The second parent-child transport device 6 connects the recoiling unit 14 and the first cross saddle 2. The third cross saddle 4 is provided on the exit side of the recoiling unit 14. The side of the third cross saddle 4 is provided adjacent to the second packaging unit 13. The steel coils of the second parent-child transport device 6 are transported to the recoiling unit 14, and then pass through the third cross saddle 4 and the second packaging unit 13 in sequence to form a second steel coil transport channel. The steel coils of the second parent-child transport device 6 are directly transported to the third cross saddle 4 and then to the second packaging unit 13 to form a third steel coil transport channel.

[0026] When transporting steel coils, any one of the three steel coil transport channels can be selected for transportation, thereby improving the flexibility of steel coil transportation.

[0027] In this embodiment, a fourth cross saddle 7 is provided on the exit side of the mother car running track of the second mother-child car transport device 6 , and the fourth cross saddle 7 is located on the entrance side of the rewinding unit 14 .

[0028] Furthermore, the steel coil transportation system based on the mother-and-child car to realize heavy coil packaging logistics also includes a first buffer saddle 8 located on the exit side of the mother car running track of the second mother-and-child car transportation device 6.

[0029] In this embodiment, a transition vehicle 9 is provided between the first buffer saddle 8 and the third cross saddle 4. The steel coil on the first buffer saddle 8 is transported to the third cross saddle 4 by the transition vehicle 9, so as to be transported to the second packaging unit 13 for packaging.

[0030] Furthermore, the steel coil transportation system based on the mother-and-child car to realize heavy coil packaging logistics also includes a fifth cross saddle 10 and a sixth cross saddle 11 located on the two finished product offline sides 15, and the fifth cross saddle 10 is located on the entrance side of the walking beam 1.

[0031] Furthermore, a transition vehicle 9 is provided between the fifth cross saddle 10 and the sixth cross saddle 11 , so that the steel coil on the sixth cross saddle 11 can be transported to the fifth cross saddle 10 via the transition vehicle 9 .

[0032] In this embodiment, a plurality of second buffer saddles 16 are provided on both sides of the mother vehicle running track of the first mother vehicle transport device 5 and the second mother vehicle transport device 6. The entrance side of the mother vehicle running track of the second mother vehicle transport device 6 is connected to the side of the mother vehicle running track of the first mother vehicle transport device 5.

[0033] In this embodiment, the transport directions of the first and second mast-carriage transport devices 5 and 6 are arranged vertically. Because the transport directions of the mast-carriages can be either perpendicular or parallel to the axis of the steel coil, the vertical arrangement of the first and second mast-carriage transport devices 5 and 6 eliminates the need to rotate the steel coils. The steel coils on one mast-carriage are placed horizontally, while the steel coils on the other mast-carriage are placed vertically. In other words, the vertical arrangement eliminates the need to rotate the steel coils, allowing them to be transported directly according to different packaging requirements, thereby improving transportation efficiency.

[0034] Specifically, the transport sub-trolleys of the first and second parent-child transport devices 5 and 6 receive the steel coils from the first cross saddle 1 .

[0035] The working process of this steel coil transportation system based on the mother-and-child vehicle to realize heavy coil packaging logistics is as follows.

[0036] The steel coil is stored on the fifth cross saddle 10 and the sixth cross saddle 11 through the finished product offline side 15. The steel coil on the sixth cross saddle 11 is transported to the fifth cross saddle 10 by the transition car 9. The finished steel coil is transported from the fifth cross saddle 10 to the first cross saddle 2 by the walking beam 1.

[0037] The first cross saddle 2 is the initial transfer point for the first parent-child transport device 5 and the second parent-child transport device 6. The first parent-child transport device 5 transfers the steel coils from the first cross saddle 2 to the second buffer saddle 16 on its side for temporary storage. Due to the unstable rhythm of the first packaging unit 12, the amount of steel coils stored on the second buffer saddle 16 varies. According to the packaging rhythm requirements of the first packaging unit 12, the first parent-child transport device 5 transports the steel coils from the second buffer saddle 16 or the first cross saddle 2 to the second cross saddle 3 for packaging by the first packaging unit 12.

[0038] The second parent-child car transport device 6 transfers the steel coil from the first cross saddle 2 to the second buffer saddle 16 on its side for temporary storage. According to the needs of the rewinding unit 14 and the second packaging unit 13, the number of steel coils stored on the second buffer saddle 16 may vary. The second parent-child car transport device 6 transports the steel coil from the first cross saddle 2 to the third cross saddle 4 or the second buffer saddle 16. The steel coil transported to the third cross saddle 4 enters the rewinding unit 14 for splitting. The split steel coils are stored on the fourth cross saddle 7. The steel coils stored on the first buffer saddle 8 are transported to the fourth cross saddle 7 by the transition car 9. The steel coils on the fourth cross saddle 7 finally enter the second packaging unit 13 for packaging.

[0039] Each coil has a unique serial number, including the width, thickness, and coil diameter of the strip, etc. Based on this information, the system or the operator determines whether the coil should be transported to the first packaging unit 12, the recoiling unit 14, or the second packaging unit 13.

[0040] The parent-child carriage can transport steel coils in two directions. Take the first parent-child carriage transport device 5 as an example. The child carriage moves the steel coil from the first cross saddle 2 to the mother carriage travel track. The mother carriage transports the steel coil along the track to a corresponding second buffer saddle 16. The child carriage deposits the steel coil on the second buffer saddle 16 perpendicular to the mother carriage travel track. The child carriage returns to the mother carriage travel track to prepare for the next coil receiving task.

[0041] The steel coil transportation system proposed in this embodiment, which utilizes a parent-child vehicle to implement recoil packaging logistics, utilizes the parent-child vehicle to implement the recoil packaging logistics transportation arrangement, connecting the continuous unwinding unit with the recoiling and packaging units, reducing intermediate manual transfers and saving manpower and energy consumption, thus facilitating the realization of an unmanned factory and energy conservation and consumption reduction. Furthermore, because this steel coil transportation system is equipped with two packaging units, steel coils that do not require recoiling unit 14 can be directly packaged. This not only improves production efficiency and reduces transportation volume, but also provides a more flexible structure (any of three steel coil transportation routes can be selected), adapting to different production needs.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
