Description
Technical Field
[0001] This utility model belongs to the field of medium and heavy plate production technology, specifically relating to a multi-channel rapid transverse transfer system. Background Technology
[0002] Medium and heavy stainless steel plates generally refer to stainless steel plates with a thickness of 4 mm or more. They are widely used in industries such as petroleum, chemical, nuclear power, shipbuilding, and machinery. Currently, medium and heavy stainless steel plates are mainly produced using offline solution treatment. In production, steel billets are typically rolled to the target thickness, straightened after laminar flow cooling, cut to length, and then cooled to room temperature. The steel plates are then transported to an annealing furnace and reheated from room temperature to the solution temperature of 1050–1150°C, held at that temperature for a period of time, and then rapidly cooled to room temperature in a quenching machine. During this process, the temperature of the steel plate cools from approximately 950°C after rolling to room temperature, and then is reheated to 1050°C during solution treatment. This process results in significant energy waste, a long production cycle, and severely limited production capacity.
[0003] To address energy waste in the production process, reduce carbon emissions per ton of steel, and achieve the goals of energy conservation, cost reduction, and efficiency improvement for enterprises, the integrated hot rolling-online solution treatment process for stainless steel has become a necessity. This process utilizes a hot-rolling mill for producing thinner gauges, followed by direct flying shearing after rolling, achieving a final rolling speed of up to 1.6 m / s. The time interval between adjacent steel plates after segmentation is less than 30 seconds. To meet capacity requirements, multiple solution treatment furnace production lines are set up, and the steel enters the next process after quenching in a quenching machine. To match the multiple solution treatment furnace production lines, a device with multi-channel lateral movement capabilities needs to be designed to meet process requirements. Utility Model Content
[0004] The purpose of this invention is to provide a multi-channel rapid lateral movement system, which can at least solve some of the defects existing in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A multi-channel rapid transverse transfer system includes several quenching machines, several quenching machine output roller conveyors, several transverse transfer table input roller conveyors, and a cold straightening machine input roller conveyor. The quenching machines are arranged in parallel side-by-side. One end of each quenching machine output roller conveyor is connected to a corresponding quenching machine, and the other end of each quenching machine output roller conveyor is connected to a corresponding transverse transfer table input roller conveyor. The cold straightening machine input roller conveyor is arranged parallel to the transverse transfer table input roller conveyors and is located outside the outermost transverse transfer table input roller conveyor. A transverse steel picking chain is provided between adjacent transverse transfer table input roller conveyors and between the cold straightening machine input roller conveyor and an adjacent transverse transfer table input roller conveyor. The conveying direction of the transverse steel picking chain is perpendicular to the conveying direction of the transverse transfer table input roller conveyors.
[0007] Furthermore, a plurality of transverse steel picking chains are provided between two adjacent transverse shifting platform input roller conveyors. These plurality of transverse shifting steel picking chains are arranged at intervals along the conveying direction of the transverse shifting platform input roller conveyor, and the end of each transverse shifting steel picking chain is staggered with the input roller of the transverse shifting platform input roller conveyor.
[0008] Furthermore, the two sides of the transverse steel chain adopt a lifting swing chain structure.
[0009] Furthermore, the transverse steel chain includes an inlet swing chain segment, a fixed chain segment, and an outlet swing chain segment arranged sequentially along its conveying direction. The inlet swing chain segment is driven by an inlet swing drive assembly to swing up and down around the connection position with the fixed chain segment. The outlet swing chain segment is driven by an outlet swing drive assembly to swing up and down around the connection position with the fixed chain segment.
[0010] Furthermore, both the inlet swing drive assembly and the outlet swing drive assembly include a hydraulic cylinder, a crank, and a rocker arm. One end of the crank is connected to the power output end of the hydraulic cylinder, and the other end of the crank is connected to the rocker arm. The rocker arm is connected to the end of the inlet swing chain segment / outlet swing chain segment away from the fixed chain segment.
[0011] Furthermore, a chain lifting roller for supporting the transverse steel chain is installed on the crank.
[0012] Furthermore, chain brackets for supporting the chain are installed on the inlet swing chain segment and the outlet swing chain segment.
[0013] Furthermore, a marking machine is provided at the end of the transverse steel chain located between the input roller table of the cold straightener and the adjacent input roller table of the transverse platform.
[0014] Furthermore, a steel transfer mechanism is provided between the transverse steel chain and the input roller table of the cold straightener.
[0015] Furthermore, the aforementioned multi-channel rapid lateral transfer system also includes a thick plate transport chain, which is located on the side of the cold straightener input roller table away from the lateral transfer steel picking chain, and the steel transfer car mechanism passes through the cold straightener input roller table and connects with the thick plate transport chain.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] The multi-channel rapid transverse transfer system provided by this utility model connects the input roller conveyors of each transverse transfer platform and the input roller conveyor of the cold straightener by designing a transverse transfer steel picking chain. This allows steel plates on multiple transverse transfer platform input roller conveyors to be transversely transported to the input roller conveyor of the cold straightener for subsequent straightening processing.

[0028] like Figure 1 and Figure 2As shown, this embodiment provides a multi-channel rapid transverse transfer system, including several quenching machines 1, several quenching machine output roller conveyors 2, several transverse transfer frame input roller conveyors 3, and a cold straightening machine input roller conveyor 6. The quenching machines 1 are arranged in parallel side by side. One end of each quenching machine output roller conveyor 2 is connected to each quenching machine 1 in a one-to-one correspondence, and the other end of each quenching machine output roller conveyor 2 is connected to each transverse transfer frame input roller conveyor 3 in a one-to-one correspondence. The cold straightening machine input roller conveyor 6 is arranged parallel to the transverse transfer frame input roller conveyor 3 and is located outside the outermost transverse transfer frame input roller conveyor 3. A transverse steel picking chain 4 is provided between two adjacent transverse transfer frame input roller conveyors 3 and between the cold straightening machine input roller conveyor 6 and an adjacent transverse transfer frame input roller conveyor 3. The conveying direction of the transverse steel picking chain 4 is perpendicular to the conveying direction of the transverse transfer frame input roller conveyor 3. During operation, multiple quenching machines 1 correspond to multiple solid solution furnace production lines. After online solution treatment, the steel plates are rapidly cooled to the target temperature by their respective quenching machines 1. After quenching, the steel plates are transported via the corresponding quenching machine output roller conveyor 2 to the corresponding transverse frame input roller conveyor 3. Steel plates on adjacent transverse frame input roller conveyors 3 are transported via transverse steel picking chains 4 to transverse frame input roller conveyors 3 closer to the cold straightener input roller conveyor 6. Steel plates requiring straightening are then transported via the cold straightener input roller conveyor 6 to the cold straightener 8 for straightening. This embodiment connects the transverse frame input roller conveyors 3 and the cold straightener input roller conveyor 6 by designing transverse steel picking chains 4, allowing steel plates from multiple transverse frame input roller conveyors 3 to be transversely transported to the cold straightener input roller conveyor 6 for subsequent straightening. This meets the capacity matching requirements of multiple solid solution furnace production lines and features a simple structure and convenient operation and maintenance.
[0029] Specifically, this embodiment uses the matching of three solid solution furnace production lines as an example. Accordingly, three quenching machines 1 are set up: quenching machine 1#, quenching machine 2#, and quenching machine 3#. These three quenching machines 1 are arranged in parallel and connected to solid solution furnaces 1# through 3# in sequence. Similarly, three output roller conveyors 2 for the quenching machines are set up: output roller conveyor 2 for quenching machine 1#, output roller conveyor 2 for quenching machine 2#, and output roller conveyor 2 for quenching machine 3#. Output roller conveyor 2 for quenching machine 1# connects to quenching machine 1#, output roller conveyor 2 for quenching machine 2# connects to quenching machine 2#, and output roller conveyor 2 for quenching machine 3# connects to quenching machine 1#. Track 2 connects to quenching machine 1 (No. 3). Quenching machine 1 processes steel plates ranging from 5mm to 120mm in diameter. The quenching speed for 5mm plates is 1m / s, and for 120mm plates it is 0.06m / s. To meet production schedule requirements, the steel plates need to be quickly removed from the output roller track 2 of the quenching machine after quenching. Therefore, the process requires the output roller track 2 of the quenching machine to have a speed ranging from 0.06m / s to 1.8m / s, which is a wide range. To meet this requirement, it is preferable that the roller motor of each output roller track 2 of the quenching machine uses a separate frequency converter drive, and each motor is equipped with one encoder. Three transverse shift table input roller conveyors 3 are also provided, namely 1# transverse shift table input roller conveyor 3, 2# transverse shift table input roller conveyor 3, and 3# transverse shift table input roller conveyor 3. Among them, 1# transverse shift table input roller conveyor 3 is connected to 1# quenching machine output roller conveyor 2, 2# transverse shift table input roller conveyor 3 is connected to 2# quenching machine output roller conveyor 2, and 3# transverse shift table input roller conveyor 3 is connected to 3# quenching machine output roller conveyor 2. The No. 1 transverse steel pick-up chain 4, located between the No. 1 transverse platform input roller conveyor 3 and the No. 2 transverse platform input roller conveyor 3, is used to transport the steel plates on the No. 1 transverse platform input roller conveyor 3 towards the No. 2 transverse platform input roller conveyor 3. The No. 2 transverse steel pick-up chain 4, located between the No. 2 transverse platform input roller conveyor 3 and the No. 3 transverse platform input roller conveyor 3, is used to transport the steel plates on the No. 2 transverse platform input roller conveyor 3 towards the No. 3 transverse platform input roller conveyor 3. The No. 3 transverse steel pick-up chain 4, located between the No. 3 transverse platform input roller conveyor 3 and the cold straightener input roller conveyor 6, is used to transport the steel plates on the No. 3 transverse platform input roller conveyor 3 towards the cold straightener input roller conveyor 6.
[0030] In an optimized implementation, a plurality of transverse steel chains 4 are provided between two adjacent transverse shifting platform input roller conveyors 3. The plurality of transverse steel chains 4 are arranged at intervals along the conveying direction of the transverse shifting platform input roller conveyor 3, and the end of each transverse steel chain 4 is staggered with the input roller of the transverse shifting platform input roller conveyor 3.
[0031] Because stainless steel requires high surface quality, in order to avoid scratching the surface of the steel plate during transportation, it is preferable to design the two sides of the transverse steel picking chain 4 to adopt a lifting swing chain structure.
[0032] As one specific implementation method, such as Figure 3As shown, the transverse steel chain 4 includes an inlet swing chain segment 10, a fixed chain segment 11, and an outlet swing chain segment 12 arranged sequentially along its conveying direction. The inlet swing chain segment 10 is driven by an inlet swing drive assembly to swing up and down around the connection position with the fixed chain segment 11. The outlet swing chain segment 12 is driven by an outlet swing drive assembly to swing up and down around the connection position with the fixed chain segment 11. Specifically, the exit swing chain segment 12 of the #1 transverse steel picking chain and the inlet swing chain segment 10 of the #2 transverse steel picking chain are arranged intersectingly between the input rollers of the #2 transverse platform input roller conveyor; the exit swing chain segment 12 of the #2 transverse steel picking chain and the inlet swing chain segment 10 of the #3 transverse steel picking chain are arranged intersectingly between the input rollers of the #3 transverse platform input roller conveyor; when the steel plate transported by the #1 quenching machine 1 arrives at the #1 transverse platform input roller conveyor 3, both the inlet swing chain segment 10 and the exit swing chain segment 12 of the #1 transverse steel picking chain 4 rise. Driven by the transmission device of the #1 transverse steel picking chain 4, the steel plate is transported from the #1 transverse platform input roller conveyor 3 to the #2 transverse platform input roller conveyor 3. When the cold metal detector detects that the steel plate has arrived at the #2 transverse platform input roller conveyor 3, the inlet swing chain segment 10 and the exit swing chain segment 12 of the #1 transverse steel picking chain 4... Both sections of the steel plate are lowered and placed on the input roller conveyor 3 of the #2 transverse shifting platform. At this time, the inlet swing chain segment 10 and the outlet swing chain segment 12 of the #2 transverse shifting steel picking chain 4 are raised to lift the steel plate. Under the action of the transmission device of the #2 transverse shifting steel picking chain 4, the steel plate is moved from the input roller conveyor 3 of the #2 transverse shifting platform to the input roller conveyor 3 of the #3 transverse shifting platform. When the cold metal detector detects that the steel plate has arrived at the input roller conveyor 3 of the #3 transverse shifting platform, both the inlet swing chain segment 10 and the outlet swing chain segment 12 of the #2 transverse shifting steel picking chain are lowered and placed on the input roller conveyor 3 of the #3 transverse shifting platform. When it is necessary to transport the steel plate on the input roller conveyor 3 of the #3 transverse shifting platform to the input roller conveyor 6 of the cold straightening machine, the inlet swing chain segment 10 of the #3 transverse shifting steel picking chain 4 is raised, and under the action of the transmission device of the #3 transverse shifting steel picking chain, the steel plate on the input roller conveyor 3 of the #3 transverse shifting platform is transported away.
[0033] Specifically, such as Figure 3 As shown, the transmission device for the transverse steel chain 4 consists of a drive motor 19, a reducer, a drive sprocket 20, and a tension sprocket 21. A tension sprocket 21 is set on each side of the drive sprocket 20. The drive motor 19 and the reducer are connected by a coupling with a brake disc and are equipped with a brake for braking protection.
[0034] In some embodiments, such as Figure 3As shown, both the inlet swing drive assembly and the outlet swing drive assembly include a hydraulic cylinder 16, a crank 15, and a rocker arm 14. One end of the crank 15 is connected to the power output end of the hydraulic cylinder 16, and the other end of the crank 15 is connected to the rocker arm 14 via a synchronous shaft. The rocker arm 14 is connected to the end of the inlet swing chain segment 10 / outlet swing chain segment 12 away from the fixed chain segment 11. The hydraulic cylinder 16 transmits power to the inlet swing chain segment 10 / outlet swing chain segment 12 through the crank 15, thereby realizing the lifting and lowering swing of the inlet swing chain segment 10 / outlet swing chain segment 12.
[0035] Preferably, the crank 15 is equipped with a chain lifting roller 13 for supporting the transverse steel chain 4. During the lifting process, the chain lifting roller 13 rolls, which helps to reduce friction. Furthermore, wear-resistant sliding plates are embedded in the swing chain frames of the inlet swing chain segment 10 and the outlet swing chain segment 12. The chain lifting roller 13 is in direct contact with the wear-resistant sliding plate, which has a long service life and can be directly replaced after long-term wear.
[0036] Optionally, in this embodiment, the chain 18 of the transverse steel chain 4 is a plate-type transport chain, with a cast iron wear-resistant plate inlaid on the upper part of the chain 18. Replacement is very convenient after wear, effectively reducing production costs. To prevent excessive deflection of thin-gauge chains during transportation, a support roller is installed between adjacent chains 18. Furthermore, chain brackets 17 are installed on the inlet swing chain segment 10 and the outlet swing chain segment 12 to support the chains 18, reducing swaying during operation and improving the stability of the transmission system.
[0037] Optimized implementation methods, such as Figure 1 As shown, a marking machine 9 is provided at the end of the transverse steel picking chain 4 located between the input roller table 6 of the cold straightening machine and the adjacent transverse table input roller table 3, for spraying a marking on the surface of the steel plate. The marking is then transmitted to the factory's secondary control system in conjunction with the steel marking scanning equipment to track the steel plate in real time and guide production management.
[0038] In a preferred embodiment, the multi-channel rapid transverse transfer system of this embodiment also includes a thick plate transport chain 7, which takes into account the subsequent processing of both thin and thick steel plates. When producing thin steel plates of less than 50mm, they enter the cold straightener input roller table 6 and are transported to the cold straightener 8 for subsequent straightening and shearing processes. When producing thick steel plates of more than 50mm, they directly enter the thick plate transport chain 7 for subsequent processing.
[0039] Specifically, a steel transfer cart mechanism 5 is provided between the transverse steel picking chain 4 and the input roller conveyor 6 of the cold straightener. The thick plate transport chain 7 is located on the side of the input roller conveyor 6 of the cold straightener away from the transverse steel picking chain 4. The steel transfer cart mechanism 5 passes through the input roller conveyor 6 of the cold straightener and connects with the thick plate transport chain 7. When the steel plate is transported to the end of the #3 transverse steel picking chain 4, it stops. At this time, the steel transfer cart mechanism 5, which has been waiting here, catches the steel plate and, driven by the transmission device of the transverse steel picking cart mechanism 5, transports the steel plate to the input roller conveyor 6 of the cold straightener or the thick plate transport chain 7. The steel transfer mechanism has a long stroke and is equipped with three stations: the No. 3 transverse steel picking link station, the cold straightening machine input roller conveyor station, and the thick plate conveyor chain unloading station. When steel plates with a production specification of less than 50mm need to enter the shearing line, the steel transfer mechanism 5 places the steel plate on the cold straightening machine input roller conveyor 6. When steel plates with a production specification of more than 50mm are produced, the steel transfer mechanism 5 places the steel plate on the thick plate conveyor chain 7 for subsequent thick plate processing.
[0040] In some embodiments, such as Figure 4 As shown, the steel transfer car mechanism 5 includes a steel transfer car track 23, a steel transfer car body 22, and a steel transfer car drive assembly 25 that drives the steel transfer car body 22 to move back and forth on the steel transfer car track 23. The steel transfer car track 23 is arranged between two adjacent input rollers of the cold straightening machine input roller table 6 and is arranged parallel to the axis of the input rollers of the cold straightening machine input roller table 6. One end of the steel transfer car track 22 is used to connect with the No. 3 transverse steel picking chain 4 so that the steel transfer car body 22 on the steel transfer car track 23 can support the steel plate on the No. 3 transverse steel picking chain 4. The other end of the steel transfer car track 23 passes through the cold straightening machine input roller table 6 and connects with the thick plate transport chain 7, so that when the steel plate does not need to be straightened, it can be directly transported to the thick plate transport chain 7 for subsequent processing.
[0041] Optimized implementation methods, such as Figure 4 As shown, the steel transfer vehicle mechanism 5 also includes a lifting drive assembly 24 for driving the lifting and lowering movement of the steel transfer vehicle track 23. The No. 3 transverse steel picking chain 4 transports the steel plate from the previous process to the end of the No. 3 transverse steel picking chain 4 and stops. After the cold metal detector detects that the steel plate has arrived, it sends a signal to the PLC system. At this time, the steel transfer vehicle body 22 of the steel transfer vehicle mechanism 5 is already waiting in the low position. When the steel transport instruction is received, the steel transfer vehicle track 23 of the steel transfer vehicle mechanism 5 rises to the high position under the drive of the lifting drive assembly 24, so that the steel transfer vehicle body 22 lifts the steel plate from the No. 3 transverse steel picking chain 4. The steel transfer vehicle body 22 carries the steel plate and moves towards the cold straightener input roller table 6. After the steel plate is transported to the cold straightener input roller table 6 / thick plate transport chain 7, the lifting drive assembly 24 can drive the steel transfer vehicle body 22 to descend back to the low position, so as not to affect the subsequent process. The lifting drive assembly 24 may adopt, but is not limited to, a crank-rocker structure, as long as it can realize the lifting movement of the steel moving car track and the steel moving car body.
[0042] The above examples are merely illustrative of the present invention and do not constitute a limitation on the scope of protection of the present invention. All designs that are the same as or similar to the present invention are within the scope of protection of the present invention.
