[0018] When the bundled high-efficiency tube blanks are transported by the hoisting structure, the staff first removes the sling of the hoisting structure, and then opens the driving assembly. When the driving assembly works, it first drives one end of the material rack assembly to move upward, and the other end of the material rack assembly is connected to the support assembly, so it will not be separated from the support assembly. At this time, the tube blanks of the high-efficiency tubes roll down to the first inclined surface of the roller mill through the first gap.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium.

[0042] This embodiment provides a sorting device, as Figures 1 - 15 shown. The sorting device cooperates with a rolling mill 5 for sorting high-efficiency tubes 6. The sorting device includes a support assembly 1, a drive assembly 2, a material rack assembly 3, and a blocking assembly 4. The material rack assembly 3 is located on the support assembly 1. One end of the support assembly 1 is connected to one end of the material rack assembly 3 through the drive assembly 2. The other end of the support assembly 1 is rotatably connected to the other end of the material rack assembly 3. Both the support assembly 1 and the blocking assembly 4 are disposed on the rolling mill 5 and there is a first gap 8 between them. When the drive assembly 2 operates, one end of the material rack assembly 3 moves in the vertical direction, so that the high-efficiency tube 6 falls onto the rolling mill 5 through the first gap.

[0043] Specifically, the rolling mill 5 has a first inclined surface 51 and a second inclined surface 52. The first inclined surface 51 and the second inclined surface 52 are supported on a bracket 53. One end of the bottom of the support assembly 1 is fixed on the second inclined surface 52, and the other end of the bottom of the support assembly 1 is located above the first inclined surface 51. The bottom of the drive assembly 2 is fixed on the second inclined surface, and the output end of the drive assembly 2 is connected to one end of the material rack assembly 3. The blocking assembly 4 is fixed on one side of the first inclined surface 51.

[0044] In this embodiment, the support assembly 1 is mainly used to support the material rack assembly 3, so that there is a height difference between the high-efficiency tube 6 on the material rack assembly 3 and the first inclined surface 51 of the rolling mill 5. The drive assembly 2 is mainly used to drive one end of the material rack assembly 3 to move up and down, so that the high-efficiency tube located on the material rack assembly 3 can be sorted during the movement. The material rack assembly 3 is mainly used to place materials. The blocking assembly 4 is mainly used to prevent the high-efficiency tube 6 from detaching from the rolling mill 5 during the sorting process. The setting of the first gap 8 provides space for sorting.

[0045] After adopting the above structure, after the bundled high-efficiency tube blanks are transported by the lifting structure, the employee first removes the sling of the lifting structure, and then turns on the driving component 2. When the driving component 2 works, it first drives one end of the material rack component 3 to move upward. Since the other end of the material rack component 3 is rotatably connected to the support component 1, it will not separate from the support component 1. At this time, the tube blanks of the high-efficiency tubes roll onto the first inclined surface 51 of the rolling mill 5 through the first gap 8. During this process, due to the presence of the blocking component 4, the tube blanks of the high-efficiency tubes will not fall, thereby realizing the sorting of the high-efficiency tubes 6; then the driving component 2 acts in the reverse direction, and one end of the material rack component 3 moves downward, and the high-efficiency tube 6 returns to the initial position; then the driving component 2 is driven to work again to drive one end of the material rack component 3 to move upward to achieve the next sorting until the bundle of high-efficiency tubes is sorted. That is to say, the sorting device provided in this embodiment makes the tube blanks of the high-efficiency tubes roll back and forth on the material rack component 3 and then fall onto the rolling mill 5 one by one through the first gap 8 through the repeated movement of the driving component 2 in different directions, so as to achieve the purpose of sorting.

[0046] In addition, it should be noted that the sorting device provided in this embodiment needs to be able to identify feeding, so its working rhythm needs to be less than that of the rolling mill 5, that is, the working structure of the driving component 2 needs to be controlled.

[0047] The sorting device provided in this embodiment replaces manual sorting with an automated method, has a high sorting efficiency, and reduces the risk of tube blank damage. It is mainly reflected in: being able to eliminate the high-intensity and somewhat dangerous work of manually sorting and transporting the high-efficiency tube blanks one by one to the rolling mill, achieving the effect of reducing the number of operators; each rolling mill 5 only needs manual hoisting and removing the sling, and the sorting device can perform automatic sorting according to the operation of the rolling mill 5.

[0048] In a specific embodiment, as Figure 1 shown, the sorting device further includes a rotating component 7, and the rotating component 7 is arranged between the other end of the support component 1 and the other end of the material rack component 3.

[0049] Specifically, one end of the support component 1 is connected to one end of the material rack component 3 through the driving component 2. During the operation of the driving component 2, one end of the material rack component 3 will move up and down. In order to prevent the other end of the support component 1 from detaching from the support component, this end needs to be connected to the material rack component 3. And, in order to cooperate with the downward movement of the material rack component 3, the other end of the support component 1 is rotatably connected to the other end of the material rack component 3.

[0050] In a specific embodiment, as Figures 8 - 10As shown, the rotating assembly 7 includes a rotating rod 71 and a clamping plate 72. One end of the rotating rod 71 is connected to the support assembly 1 and can rotate relative to the support assembly 1. The other end of the rotating rod 71 is rotatably connected to the clamping plate 72, and the clamping plate 72 is fixed to the material rack assembly 3.

[0051] The rotating rod 71 is a rod-shaped structure with a bearing seat 73 at its end. The bearing seat 73 is installed on the top of the support assembly 1. When the material rack assembly 3 rotates, one end of the rotating rod 71 can rotate within the bearing. The clamping plate 72 is a plate-shaped structure with a connection hole 721 at one end, and the other end of the rotating rod 71 passes through the connection hole 721. Specifically, the material rack assembly 3 is welded and fixed to the clamping plate 72, the clamping plate 72 is clamped and fixed to the rotating rod 71 by screws, and the rotating rod 71 is fastened to the support assembly 1 by screws. In this way, with the above structure, the rotating rod 71 and the clamping plate 72 connect the support assembly 1 and the material rack assembly 3, ensuring that the reciprocating motion of the driving assembly 2 drives the material rack assembly 3 to perform reciprocating motion, achieving the purpose of efficient pipe rolling sorting. The above rotating rod 71 is a steel pipe with a diameter of 25 mm, and the model of the above bearing seat is BGHFB-C625ZZ-15.

[0052] In a specific embodiment, as Figure 13 and Figure 14 shown, the material rack assembly 3 includes a material plate 31. One end of the material plate 31 away from the blocking assembly 4 extends upward to form a first baffle 32; and one end of the material plate 31 near the first baffle 32 has a first state of inclining downward and a second state of inclining upward.

[0053] The material rack assembly 3 further includes a protective layer wrapped outside the first baffle 32. The protective layer is a 0.8 mm thick stainless steel plate, which can prevent the high-efficiency pipe 6 from being bruised or scratched. In addition, the material rack assembly 3 further includes a frame 33 disposed around the bottom of the material plate 31 and / or the outside of the first baffle 32. The frame 33 is used to increase the structural strength of the material rack assembly 3.

[0054] And, as Figure 14 and Figure 15 shown, a load-bearing member 34 is further provided at the bottom end of the first baffle 32. The load-bearing member 34 is used to ensure the structural stability.

[0055] In the initial state of the driving assembly 2, one end of the material plate 31 near the first baffle 32 inclines downward. As Figure 5 shown, this is the above-mentioned first state. At this time, it can prevent the high-efficiency pipe 6 from shaking on the material plate 31. In another state of the driving assembly 2, one end of the material plate 31 near the first baffle 32 inclines upward. As Figure 4As shown, this is the aforementioned second state. At this time, the high-efficiency tube 6 can slide down onto the rolling mill 5 along the first gap 8 to achieve sorting.

[0056] In a specific embodiment, the driving assembly 2 includes a telescopic cylinder. When the telescopic cylinder is in a contracted state, one end of the material rack assembly 3 away from the blocking assembly 4 inclines downward. When the telescopic cylinder is in an extended state, one end of the material rack assembly 3 close to the blocking assembly 4 inclines downward.

[0057] Specifically, the model of the telescopic cylinder is CG3DN40-75, and it is equipped with a cylinder base 21. As Figure 6 shown, the model of the base fitting is CG-040-24A_CG3, and it also has a cylinder support fitting 22. The model of the cylinder support fitting is Y-G04_(40)CG3.

[0058] In a specific embodiment, as Figures 1 - 3 shown, multiple groups of the material rack assembly 3 are provided, and multiple groups of the material rack assembly 3 are arranged at intervals on the support assembly 1; the number of the telescopic cylinders is the same as that of the material rack assembly 3 and they are arranged in one-to-one correspondence.

[0059] In one embodiment, four groups of telescopic cylinders and the material rack assembly 3 are both provided. Specifically, the cylinder diameter of the telescopic cylinder is 40mm, the stroke is 75mm, each telescopic cylinder generates a thrust of 60 kilograms under one atmospheric pressure, and the entire sorting device includes 4 telescopic cylinders, generating a total thrust of 240 kilograms, which can act on 60 high-efficiency tubes 6.

[0060] In a specific embodiment, the width L1 of the first gap 8 satisfies: d < L1 < 2d; where d is the diameter of the high-efficiency tube 6. The width L1 of the first gap 8 is set such that the sorting device provided in this embodiment can sort one high-efficiency tube 6 at a time, avoiding incomplete sorting caused by sorting multiple high-efficiency tubes 6 simultaneously.

[0061] In a specific embodiment, as Figure 7 shown, the support assembly 1 includes a plurality of cross bars 11 and a plurality of vertical bars 12. The plurality of cross bars 11 and the plurality of vertical bars 12 are arranged crosswise to form the support assembly 1; there is a second gap 9 between one side of the bottom of the support assembly 1 close to the blocking assembly 4 and the rolling mill 5, and the bottom of the support assembly 1 away from the blocking assembly 4 is connected to the rolling mill 5.

[0062] After the high-efficiency tube 6 falls onto the rolling mill 5 through the first gap 8, it is located between the blocking assembly 4 and the vertical bar 12 of the support assembly 1 close to the blocking assembly 4. Then, the high-efficiency tube 6 will pass through the second gap 9 and gradually accumulate on the first inclined surface 51 along the first inclined surface 51.

[0063] In a specific embodiment, the height L2 of the second gap 9 satisfies: d < L2 < 2d; where d is the diameter of the high-efficiency tube 6. Limiting the height L2 of the second gap 9 enables the high-efficiency tube 6 to pass through singly, avoiding the technical problem that excessive high-efficiency tubes 6 passing through the second gap 9 may collide with each other, causing damage to the high-efficiency tubes.

[0064] In a specific embodiment, as Figure 11 and Figure 12 shown, the blocking component 4 includes one or more second baffles. When there are multiple second baffles, the multiple second baffles are arranged at intervals; and the top of the second baffle is higher than the top of the other end of the material rack component 3.

[0065] The surface of the second baffle is wrapped with a stainless steel plate with a thickness of 0.8 mm, which can prevent the high-efficiency tube 6 from being bruised or scratched.

[0066] In a specific embodiment, the sorting device further includes a photoelectric induction component. The photoelectric induction component is arranged on the blocking component 4 and faces the first gap 8; when it senses that the number of high-efficiency tubes 6 on the rolling mill 5 exceeds a preset value, the driving component 2 stops working.

[0067] Specifically, the photoelectric induction component can be a photoelectric sensor, which can judge the height of the high-efficiency tubes 6 currently stacked in the first gap 8 through a light emitter and a light receiver. When the height exceeds the preset value, it proves that the workload of the rolling mill 5 has reached saturation. At this time, the driving component 2 controls the sorting device to stop working.

[0068] Multiple experimental verifications were carried out on the sorting device provided in this embodiment. During the verification process, two situations occurred for the high-efficiency tubes 6. The first was that a single high-efficiency tube 6 dropped, which met the sorting requirements at this time; the second was that multiple high-efficiency tubes 6 interfered with each other and could not drop. At this time, as the telescopic cylinder retracted, all the high-efficiency tubes 6 returned to the initial state, and when the telescopic cylinder extended and retracted again, a single high-efficiency tube 6 could drop smoothly, which also met the sorting requirements.

[0069] The sorting device provided in this embodiment is convenient to use and has high efficiency. It can eliminate the high-intensity and somewhat dangerous work of manually sorting and conveying the high-efficiency tube blanks singly to the rolling mill, achieving the effect of reducing the number of operators; and for each rolling mill, only manual lifting of materials and removal of slings are required, and the sorting device can perform automatic sorting according to the operating conditions of the rolling mill.

[0070] In summary, it is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0071] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Any simple modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
