Description

Technical Field

[0001] This invention relates to the field of steel strip transfer technology, specifically an auxiliary steel strip transfer and feeding device. Background Technology

[0002] Annealing is a crucial step in the production and processing of steel strips. Before annealing, the steel strips need to be transferred from the storage location to the loading area. Therefore, the efficiency and safety of the steel strip transfer and loading directly affect the overall production progress and operational safety.

[0003] Currently, steel strip transfer in the industry mostly adopts two methods: one is fixed grippers combined with overhead crane transfer. This method has obvious limitations, as it can only transfer a fixed number of steel strips and cannot achieve batch transfer, resulting in low transfer efficiency and difficulty in meeting the needs of large-scale production.

[0004] Another method is to use grooved pallets with forklifts for transport. Grooved pallets are heavy, which increases the load during transport. In addition, their structural design is flawed, making it difficult to effectively limit the inner ring of the steel strap. During transport, the steel strap is prone to slipping, which seriously affects the overall safety of the transport and may also damage the surface of the steel strap, increasing production costs.

[0005] In addition, both traditional transfer methods require manual positioning and adjustment, which is cumbersome, labor-intensive, and prone to operational errors, further reducing production efficiency.

[0006] Based on this, the present invention provides an auxiliary steel strip transfer and feeding device to solve the above problems. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides an auxiliary steel strip transfer and feeding device. The present invention has an ingenious structure and focuses on practicality, effectively solving the technical problems of low transfer efficiency, poor transfer safety and poor positioning effect of manual adjustment.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An auxiliary steel strip transfer and feeding device includes a bottom support, a connecting sleeve fixedly installed on the top of the bottom support, two symmetrical primary guide grooves penetrating the surface of the connecting sleeve, a primary guide rod slidably connected inside each of the two primary guide grooves, and the same pin fixedly installed on one end face of each of the two primary guide rods.

[0010] Preferably, the upper end face of the connecting sleeve is machined with a guide slope near the primary guide groove, and the primary guide groove is a J-shaped through groove.

[0011] Preferably, a contact head is fixedly installed on the bottom end face of the pin.

[0012] Preferably, two symmetrically distributed auxiliary handles are fixedly mounted on the surface of the pin.

[0013] Preferably, an auxiliary lifting ring is fixedly installed on the surface of the pin near its upper end.

[0014] Preferably, the inner surface of the connecting sleeve is provided with symmetrically arranged secondary guide grooves located below the primary guide groove, and a sliding block is slidably connected in the secondary guide groove, with the same secondary guide rod fixed between the two sliding blocks.

[0015] Preferably, a rotating ring is rotatably installed inside the connecting sleeve, and the secondary guide rod is rotatably installed inside the rotating ring.

[0016] Preferably, multiple connecting rods are fixedly installed above the rotating ring, and the upper ends of the multiple connecting rods are fixed with the same contact plate. A compression spring is fixedly installed between the rotating ring and the connecting sleeve.

[0017] Preferably, the rotating ring has a storage groove for storing the sliding blocks, and the two sliding blocks are always kept in a state where one is in the storage groove and the other is outside the storage groove.

[0018] The present invention has the following technical advantages.

[0019] 1. This invention uses a bottom support and a connecting sleeve to carry multiple sets of steel strips in batches, eliminating the need for multiple individual transfers and greatly improving the efficiency of steel strip transfer. The bottom support and connecting sleeve can effectively limit the lower surface and inner ring of the steel strip, avoiding the problems of traditional grooved pallets being difficult to limit and easy to fall off, which cannot guarantee safety.

[0020] 2. The two symmetrically arranged secondary guide grooves of this invention serve as the loading groove and the unloading groove, respectively. With the help of the sliding block, the storage groove and the compression spring, the loading and unloading processes can be switched in an orderly manner, ensuring a smooth and continuous transfer process, reducing manual adjustments and further improving overall work efficiency.

[0028] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 4 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0029] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] This invention relates to an auxiliary steel strip transfer and feeding device, comprising a bottom support 1, a connecting sleeve 2 fixedly installed on the top of the bottom support 1, two centrally symmetrical primary guide grooves 3 penetrating the surface of the connecting sleeve 2, and primary guide rods 8 slidably connected inside the two primary guide grooves 3, with the same pin 5 fixedly installed on one end face of each of the two primary guide rods 8. A guide slope 4 is machined on the upper end face of the connecting sleeve 2 near the primary guide grooves 3, and the guide slope 4 guides the primary guide rods 8. In actual operation, this allows the pin 5 connected to the primary guide rods 8 to quickly and efficiently enter the primary guide grooves 3. The primary guide grooves 3 are J-shaped through grooves. By setting the primary guide grooves 3 as J-shaped through grooves, when the primary guide rods 8 rotate into the end of the J-shaped groove of the primary guide groove 3, the entire structure can be lifted by pulling up the pin 5 with the help of a crane. The bottom support 1 is a rectangular structure, and the bottom support 1, together with the connecting sleeve 2, can limit the lower surface and inner ring of the steel strip, ensuring the stability of subsequent steel strip transfer.

[0031] In this embodiment, when the steel strip that needs to be annealed is transferred, multiple sets of steel strips can be lifted to the upper surface of the bottom support 1 multiple times by a crane and a lifting device. At the same time, the connecting sleeve 2 is placed in the inner ring of the steel strip. After the steel strip is put in, the pin 5 is aligned and put into the connecting sleeve 2. During the insertion process, the first-level guide rod 8 on the surface of the pin 5 will gradually enter the first-level guide groove 3 through the guide slope 4. After entering, the first-level guide rod 8 is adjusted to the end face of the first-level guide groove 3. At this time, by moving the pin 5, the pin 5 drives the connecting sleeve 2 and the steel strip to move through the first-level guide rod 8, thereby realizing the transfer of the connecting sleeve 2.

[0032] When the steel strip is transferred to the appropriate position, the first-stage guide rod 8 can be adjusted in the reverse direction to disengage the first-stage guide rod 8 and the pin 5 from the connecting sleeve 2. At this point, the steel strip can be annealed.

[0033] Note: Currently, steel strip transfer mostly uses fixed grippers with overhead cranes or grooved pallets with forklifts. Fixed grippers can only handle a fixed number of steel strips, so the transfer efficiency cannot be guaranteed. Grooved pallets are heavy and it is difficult to limit the inner ring of the steel strip during the transfer process, which affects the overall safety of the transfer.

[0034] As an example, a contact head 10 is fixedly installed on the bottom end face of the pin 5. The contact head 10 has a conical structure. By setting the contact head 10 to a conical structure, the contact head 10 can quickly enter the connecting sleeve 2 during actual operation. The contact head 10 can perform more effective guidance and positioning, thereby improving the positioning and installation efficiency of the pin 5.

[0035] In this embodiment, during the connection process between the pin 5 and the connecting sleeve 2, the lower part of the contact head 10 will first enter the upper opening of the connecting sleeve 2. Because the lower part of the contact head 10 has a smaller volume, it is easier for it to enter the connecting sleeve 2. Even if the initial position is deviated from the center of the connecting sleeve 2, the inclined surface of the contact head 10 can correct its own position in the opposite direction until part of the structure of the pin 5 smoothly enters the connecting sleeve 2.

[0036] As an example, two symmetrically distributed auxiliary handles 6 are fixedly installed on the surface of the pin 5. The auxiliary handles 6 are set in an inclined shape to facilitate the use of the staff.

[0037] As an example, the auxiliary lifting ring 7 is a ring structure. The auxiliary lifting ring 7 is fixedly installed on the surface of the pin 5 near the upper end. The auxiliary lifting ring 7 and the pin 5 form a ring-shaped sealing structure, which can more effectively prevent disengagement and provide safety for transportation and lifting.

[0038] As an example, the inner surface of the connecting sleeve 2 is also provided with two symmetrically arranged secondary guide grooves 9. Each of the two secondary guide grooves 9 is composed of a long vertical groove, a short vertical groove, and an inclined groove that connects the two vertical grooves. The upper surface of the short vertical groove is machined with a sloping rounded corner, that is, when the sliding block 15 moves to this position, it will squeeze the sliding block 15 to retract inward. One of the secondary guide grooves 9 is a feeding groove, and the other secondary guide groove 9 is a discharging groove.

[0039] Sliding blocks 15 are slidably connected in both secondary guide grooves 9. The same secondary guide rod 14 is fixedly installed on one end face of the two sliding blocks 15. Specifically, in the initial state, one of the sliding blocks 15 at both ends of the secondary guide rod 14 is placed in the long vertical groove and the other is placed in the short vertical groove.

[0040] The connecting sleeve 2 is provided with a rotating ring 13. The secondary guide rod 14 is rotatably connected in the rotating ring 13. Multiple symmetrically distributed connecting rods 12 are fixedly installed above the rotating ring 13. The upper end face of the multiple connecting rods 12 is fixedly installed with the same contact plate 11 that can contact the contact head 10. The surfaces of the contact head 10 and the contact plate 11 are respectively provided with a cross-shaped locking block and a cross-shaped locking groove. A compression spring 17 is fixedly installed between the rotating ring 13 and the connecting sleeve 2. The rotating ring 13 is also provided with a storage groove 16 that can accommodate the sliding block 15. The two sliding blocks 15 are always kept in a state where one is in the storage groove 16 and the other is outside the storage groove 16.

[0041] Note: In the initial state, the sliding block 15 in the secondary guide groove 9 (feeding groove) is placed outside the storage groove 16, and it corresponds to the position of the long vertical groove of the secondary guide groove 9, while the other sliding block 15 is placed above the short vertical groove of the secondary guide groove 9 (feeding groove).

[0042] In this embodiment, when the pin 5 is inserted, the lower surface of the contact head 10 gradually contacts the contact plate 11. Relying on the weight of the pin 5 and the contact head 10, the contact plate 11 is pressed down. During the descent, the contact plate 11 drives the connecting rod 12 and the rotating ring 13 to descend. At this time, one of the sliding blocks 15 slides down inside the secondary guide groove 9 (feeding groove). When the sliding block 15 and the rotating ring 13 descend into the inclined groove, they rotate and descend at the same time, thereby driving the contact plate 11 to rotate during the descent, and driving the contact plate 11 and the pin 5 to rotate. This rotation process drives the primary guide rod 8 to gradually move to the position below the tail end of the J structure of the primary guide groove 3, automatically pulling the primary guide rod 8 to the lifting position. After the pull, the pin 5 is lifted directly, thereby driving the connecting sleeve 2, the bottom support 1, and the steel belt to rise and fall.

[0043] During the hoisting process, the spring 17 rebounds, pushing the rotating ring 13, connecting rod 12 and contact plate 11 to rise, continuously pushing the sliding block 15 placed in the secondary guide groove 9 (feeding groove) to disengage from the short vertical groove of the secondary guide groove 9 (feeding groove). During the disengagement process, this sliding block 15 will also be squeezed into the receiving groove 16 by the inner wall slope rounded corner of the connecting sleeve 2. At this time, another sliding block 15 will be placed in the long vertical groove of the secondary guide groove 9 (discharge groove) and will extend and be stuck into the secondary guide groove 9 (discharge groove);

[0044] When it is necessary to unload the contact head 10 and the pin 5, first lower the pin 5. Relying on its weight, the contact plate 11 is pressed down and the above movement is repeated. At this time, the sliding block 15 placed in the secondary guide groove 9 (unloading groove) is driven to slide. Since the secondary guide groove 9 (unloading groove) and the secondary guide groove 9 (loading groove) are symmetrically arranged, the secondary sliding drives are downward counterclockwise rotation and downward clockwise rotation, respectively. Therefore, when the sliding block 15 rotates in the secondary guide groove 9 (unloading groove), it will drive the contact plate 11 and the pin 5 to rotate in the opposite direction, thereby causing the primary guide rod 8 to disengage from the primary guide groove 3.

[0045] Working principle:

[0046] S1. First, use a crane and a lifting device to lift multiple sets of steel strips to the upper surface of the bottom support 1, so that the connecting sleeve 2 is placed in the inner ring of the steel strip to achieve the limit. Then, align the pin 5 with the connecting sleeve 2 and put it in. The contact head 10 first enters the connecting sleeve 2 and corrects its position through its own conical structure. The first-stage guide rod 8 is guided into the first-stage guide groove 3 through the guide slope 4.

[0047] S2. Simultaneously, the contact head 10 presses down on the contact plate 11, causing the connecting rod 12 and the rotating ring 13 to descend, so that the sliding block 15 rotates and descends along the secondary guide groove 9 (feeding groove), pulling the primary guide rod 8 to below the J-shaped tail end of the primary guide groove 3. Then, the pin 5 is lifted by the auxiliary lifting ring 7, which drives the connecting sleeve 2, the bottom support 1 and the steel strip to move. During the upward movement of the pin 5, the compression spring 17 rebounds, causing the sliding block 15 in the secondary guide groove 9 (feeding groove) to be retracted into the receiving groove 16. The sliding block 15 in the secondary guide groove 9 (unfeeding groove) extends out and is inserted.

[0048] S3. When the strip is moved to the appropriate position, the pin 5 is lowered and the contact head 10 presses down the contact plate 11 again, so that the sliding block 15 rotates in the opposite direction along the secondary guide groove 9 (feeding groove), which drives the primary guide rod 8 to disengage from the primary guide groove 3. After the pin 5 is removed, the steel strip can be annealed.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
