Description

Technical Field

[0001] The present invention relates to the technical field of steel plate production equipment, specifically a device for realizing the rotation function of OAL. Background Art

[0002] OAL, that is, the transition connection channel, is mainly used for the passage of steel plate transfer. The designed production capacity of the continuous annealing unit is 960,000 tons of ordinary cold-rolled products per year. At present, the actual production load has been at a low level for a long time, and the equipment has been stopped for a long time, resulting in serious waste. However, the market demand for hot-dip galvanized products is very large. At the same time, the equipment and technological processes before and after the continuous annealing unit and the galvanizing unit are basically the same. The continuous annealing unit has been transformed into a dual-purpose production line that can produce both ordinary cold-rolled products and galvanized products. When switching to the production of cold-rolled products, it must pass through a transition connection channel as a transition. When producing galvanized products, this channel must be removed and moved away. Otherwise, it will occupy the space of the galvanized product production channel. When switching back to the production of cold-rolled products, this transition connection channel must be installed again. The transition connection channel is large in volume and heavy in weight. The disassembly, hoisting space is limited, and it is also a high-altitude operation. The hidden safety hazards of disassembly and hoisting are large, the time-consuming is long, and the operation efficiency is low, which affects the switching time. Therefore, it is necessary to study a structure that can automatically rotate and adjust the position of the transition connection channel, so as to facilitate two different construction processes for steel plates.

[0003] The defects of the existing steel plate production equipment are as follows:

[0004] 1. The patent document CN211866222U discloses a pipe coil-to-coil continuous annealing unit, "including an unwinding device for passively unwinding the coil stock and inputting protective gas into the pipe cavity of the coil stock; a decoiling and straightening device for actively uncoiling the coil stock and straightening the pipe after uncoiling; an annealing device for annealing the pipe; an inlet pinch device for pinching and feeding the pipe into the annealing device; an outlet pinch device for pinching and feeding the pipe out of the annealing device; and a winding device for winding the annealed pipe; the unwinding device, the decoiling and straightening device, the inlet pinch device, the annealing device, the outlet pinch device, and the winding device are arranged in sequence. The annealing unit for pipes can effectively reduce the length of the equipment, save the equipment occupation space and site cost, and facilitate the equipment layout; it can have multiple annealing channels, and can perform single-channel annealing treatment or multi-channel annealing treatment according to actual working requirements, which is convenient and flexible to use, and the pipes in each annealing channel do not interfere with each other", however, the above-mentioned disclosed pipe coil-to-coil continuous annealing unit in the patent document mainly considers performing single-channel annealing treatment or multi-channel annealing treatment according to actual working requirements, and does not consider the problem of quickly switching the steel plate structure production line. Therefore, it is necessary to study a structure that can adjust the transition connection channel, so as to facilitate the quick switching of the steel plate production line;

[0005] 2. Patent document CN207628885U discloses a stainless steel cold-rolled sheet continuous production system, "at least including a black coil pickling unit, a stainless steel white coil rolling unit, and an annealing pickling unit, wherein the black coil pickling unit, the stainless steel white coil rolling unit, and the annealing pickling unit are sequentially connected together to form a continuous unit; no intermediate annealing section is provided between the black coil pickling unit and the stainless steel white coil rolling unit. The black coil pickling is connected with the stainless steel white coil rolling, annealing pickling and other processes to form a continuous unit, and 2B / 2D products are directly produced, black coil annealing, intermediate annealing, and the transportation of steel coils between processes are omitted, the yield rate is improved, and the factory construction land and engineering investment are saved to a great extent." However, the stainless steel cold-rolled sheet continuous production system in the above-mentioned public document mainly considers the improvement of the yield rate, and does not consider the problem of checking the position of the transition connection channel. Therefore, it is necessary to study a structure that can detect the position of the transition connection channel, thereby preventing the transition connection channel from being completely moved to the connection point and affecting the transportation of the steel plate.

[0016] The operation method of the device for realizing the rotation function of OAL is applicable to the device for realizing the rotation function of OAL described in any one of the above, and includes:

[0017] S1. When galvanized products need to be produced, the steel plate comes down from the grate and falls into the zinc pot for galvanizing. The steel plate is turned vertically upward through the turning roller of the YG device and sent to the galvanized product channel through the electromagnetic induction heater;

[0018] S2. When producing cold-rolled products, the steel plate comes down from the furnace grate. The electric hoist lowers the transition connection channel through the towing rope. The transition connection channel rotates counterclockwise around the rotation axis to the channel connection position by its own weight. The first telescopic rod pushes the extension slot out of the transition connection channel. The steel plate enters the cold-rolled product channel through the transition connection channel and the transfer channel, realizing the production of cold-rolled products.

[0019] S3. When the production of cold-rolled products is completed and galvanized products are to be produced again, the electric hoist pulls up the transition connection channel through the towing rope. The transition connection channel rotates clockwise to the folding and fixing position, realizing the production of galvanized products.

[0020] Preferably, in step S2, the following steps are further included:

[0021] S21. When using the transition connection channel to produce cold-rolled products, make the second telescopic rod work to drive the limit block to move. After the limit block moves to the outer wall of the pressure block, the position of the transition connection channel can be limited through the pressure block, thereby improving the stability of the transition connection channel.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The present invention adjusts and rotates the position of the transition connection channel through the installation of an adjustment component and an electric hoist for adjusting the steel plate production line. When producing cold-rolled products, the steel plate comes down from the furnace grate. Make the electric hoist work to no longer limit the transition connection channel through the towing rope. The transition connection channel rotates counterclockwise around the rotation axis to the channel connection position by its own weight. Make the first telescopic rod work to push the extension slot out of the inside of the transition connection channel. Switch the channel turning roller to make the steel plate move into the inside of the extension slot. The micro motor works to make the micro conveyor belt move to convey the steel plate. The steel plate enters the inside of the cold-rolled product channel through the transfer channel for production, realizing the production of cold-rolled products. Through this operation, a fast, efficient, convenient and safe switching function is realized, enabling the steel plate to be processed to enter different processing production lines for processing without disassembling the transition connection channel, reducing the labor intensity.

[0024] 2. The present invention can adjust the position of the transition connection channel by installing a detection component. When producing cold-rolled products, to prevent the position of the transition connection channel from not rotating and moving to the connection point, after the transition connection channel moves to the connection point, the pressing block pushes the sliding block to move. When the sliding block moves, it pushes the power supply component to move through the sliding rod. The movement of the power supply component makes the conductive column move into the interior of the conductor. The current inside the power supply component flows through the conductor and into the interior of the warning light, causing the warning light to light up. The first spring pushes the sliding block to reset, and then the conductive column can be reset. After the transition connection channel does not move to the connection point, the conductive column will not enter the interior of the conductor. Therefore, it can be judged whether the transition connection channel has moved to the connection point through the warning light, which is convenient for the transition connection channel to convey the steel plate.

[0025] 3. The present invention can stir the zinc liquid inside the zinc pot by installing a square frame and fan blades. When the cleaned steel plate moves into the interior of the zinc pot for galvanizing, after the steel plate is galvanized, the fourth telescopic rod works to push the square frame to move. The square frame makes the galvanized steel plate move out of the interior of the zinc liquid through the rotating roller. The output end of the driving motor rotates to drive the rotating roller to rotate. When the rotating roller rotates, the galvanized steel plate moves into the interior of the electromagnetic induction heater for heat processing. When the square frame moves, the output end of the micro motor rotates to drive the fan blades to rotate. The rotation of the fan blades stirs the zinc liquid, which can prevent the generation of sediment in the zinc liquid. At the same time, stirring the zinc liquid can prevent the occurrence of uneven zinc liquid temperature. After the fan blades are completely separated from the zinc liquid, the rotation of the fan blades generates wind power, which can remove the zinc liquid adsorbed on the outer wall of the square frame.

The shape of the conductor 33 is cylindrical, and the conductor 33 is electrically connected to the warning light.

[0046] Please refer to Figure 1-6, The adjustment component includes an electric hoist 8 and a transition connection channel 5. A traction rope 11 is provided at the output end of the electric hoist 8. The transition connection channel 5 includes a first telescopic rod 16 and an extension slot 17. A rotating shaft 9 is provided at one end of the transition connection channel 5. One end of the cold-rolled product channel 7 is equipped with a transfer channel 13. The adjustment component is installed at one end of the transfer channel 13. An installation slot 18 is provided on the inner wall of the extension slot 17. A micro conveyor belt 19 is provided on the inner wall of the installation slot 18. A micro motor 20 is installed on the inner wall of the extension slot 17 and the micro motor 20 is connected to the micro conveyor belt 19 through belt drive. A hook 15 is provided on the outer wall of one side of the transition connection channel 5, and one end of the traction rope 11 is fixedly connected to the hook 15. A pressing block 24 is provided at the bottom of the transition connection channel 5. Multiple connecting frames 21 are provided at the bottom of the transfer channel 13. A second telescopic rod 22 is provided on the inner wall of the connecting frame 21. A limiting block 23 is fixedly installed at one end of the second telescopic rod 22. When producing cold-rolled products, the steel plate comes down from the grate 1. The electric hoist 8 works and no longer limits the transition connection channel 5 through the traction rope 11. The transition connection channel 5 rotates around the rotating shaft 9 by its own weight. The transition connection channel 5 rotates counterclockwise to the channel connection position, causing the first telescopic rod 16 to work and push the extension slot 17 out of the interior of the transition connection channel 5. The channel switching roller 6 is switched to move the steel plate into the interior of the extension slot 17. The micro motor 20 works to move the micro conveyor belt 19 to convey the steel plate. The steel plate enters the interior of the cold-rolled product channel 7 through the transfer channel 13 for production, realizing the production of cold-rolled products. Through this design and operation, a fast, efficient, convenient and safe switching function is achieved.

[0047] Please refer to Figure 7, a detection component 25 is provided on the inner wall of the transfer channel 13. The detection component 25 includes a guide ring 26 and a sliding rod 27. One end of the sliding rod 27 penetrates through the inside of the guide ring 26. A sliding block 29 is fixedly installed at one end of the sliding rod 27. A power supply component 30 is provided at the other end of the sliding rod 27. A first spring 28 is fixedly provided on the outer wall of the guide ring 26. One end of the sliding rod 27 penetrates through the inside of the first spring 28. A conductive column 31 is provided on the outer wall of the power supply component 30. An installation frame 32 is provided on the inner wall of the detection component 25. A conductor 33 is provided on the inner wall of the installation frame 32. A warning light is provided at the top of the transfer channel 13. When producing cold-rolled products, to prevent the position of the transition connection channel 5 from not rotating and moving to the connection point, after the transition connection channel 5 moves to the connection point, the pressing block 24 will push the sliding block 29 to move. When the sliding block 29 moves, it will push the power supply component 30 to move through the sliding rod 27. When the power supply component 30 moves, the conductive column 31 will move into the inside of the conductor 33. The current inside the power supply component 30 will flow through the conductor 33 and into the inside of the warning light, causing the warning light to light up. The first spring 28 will push the sliding block 29 to reset, and then the conductive column 31 can be reset. After the transition connection channel 5 does not move to the connection point, the conductive column 31 will not enter the inside of the conductor 33. Then, it can be judged whether the transition connection channel 5 has moved to the connection point through the warning light, which is convenient for the transition connection channel 5 to convey the steel plate.

[0048] Please refer to Figure 8 and Figure 9 , a sealing box 35 is provided on the inner wall of the zinc pot 5. Multiple groups of third telescopic rods 36 are provided on the inner wall of the sealing box 35. A square frame 37 is fixedly installed at the top of the third telescopic rods 36. Multiple groups of rotating rollers 38 are provided on the inner wall of the square frame 37. Rotating wheels 39 are installed at both ends of the rotating rollers 38, and the rotating wheels 39 are connected by a belt drive. A driving motor 40 is provided on the inner wall of the square frame 37, and the output end of the driving motor 40 is fixedly connected to one end of one group of rotating rollers 38. Multiple groups of sealing shells 41 are sequentially provided at the bottom of the square frame 37. A micro motor 42 is installed on the inner wall of the sealing shell 41. A fan blade 34 is installed at the output end of the micro motor 42. When the cleaned steel plate moves into the zinc pot 5 for galvanizing, after the steel plate is galvanized, the third telescopic rods 36 are operated to push the square frame 37 to move. The square frame 37 moves the galvanized steel plate out of the zinc liquid through the rotating rollers 38. The output end of the driving motor 40 rotates to drive the rotating rollers 38 to rotate. When the rotating rollers 38 rotate, the galvanized steel plate moves into the electromagnetic induction heater 4 for hot processing. When the square frame 37 moves, the output end of the micro motor 42 rotates to drive the fan blade 34 to rotate. The fan blade 34 rotates to stir the zinc liquid, which can prevent the zinc liquid from producing precipitates. At the same time, after the fan blade 34 is completely separated from the zinc liquid, the fan blade 34 rotates to generate wind power, and the wind power can remove the zinc liquid adsorbed on the outer wall of the square frame 37.

[0049] The operation method of the device for realizing the rotation function by OAL, which is applicable to the device for realizing the rotation function by OAL described in any one of the above, includes:

[0050] S1. When galvanized products need to be produced, the steel plate comes down from the grate 1, falls into the zinc pot 3 for galvanizing, and is turned vertically upward by the turning roller 2 of the YG device, and then goes to the galvanized product channel through the electromagnetic induction heater 4;

[0051] S2. When cold-rolled products are produced, the steel plate comes down from the grate 1, and the electric hoist 8 lowers the transition connection channel 5 through the traction rope 11. The transition connection channel 5 rotates counterclockwise around the rotation shaft 9 to the channel connection position by its own weight. The first telescopic rod 16 pushes the extension slot 17 to extend out of the transition connection channel 5, and the steel plate enters the cold-rolled product channel 7 through the transition connection channel 5 and the transfer channel 13 to realize the production of cold-rolled products;

[0052] S3. When the production of cold-rolled products is completed and galvanized products need to be produced again, the electric hoist 8 pulls up the transition connection channel 5 through the traction rope 11, and the transition connection channel 5 rotates clockwise to the folding and fixing position to realize the production of galvanized products.

[0053] In step S2, the following steps are further included:

[0054] S21. When using the transition connection channel 5 to produce cold-rolled products, the second telescopic rod 22 works to drive the limit block 23 to move. After the limit block 23 moves to the outer wall of the pressure block 24, the position of the transition connection channel 5 can be limited through the pressure block 24, thereby improving the stability of the transition connection channel 5.

[0055] Working principle: First, when producing products, when producing galvanized products, the steel plate comes down from the furnace grate 1 and falls into the zinc pot 3 for galvanizing. After galvanizing, the steel plate is turned vertically upward by the turning roller 2 of the YG device through the zinc pot 3, and then goes to the galvanized product channel through the electromagnetic induction heater 4. When producing cold-rolled products, the steel plate comes down from the furnace grate 1, and the electric hoist 8 works to no longer limit the transition connection channel 5 through the traction rope 11. The transition connection channel 5 rotates counterclockwise around the rotating shaft 9 to the channel connection position by its own weight, so that the first telescopic rod 16 works to push the extension groove 17 to move out of the inside of the transition connection channel 5. The steel plate is turned obliquely upward to the transition connection channel 5 through the switching channel turning roller 6. The micro motor 20 works to move the micro conveyor belt 19 to convey the steel plate. The steel plate enters the inside of the cold-rolled product channel 7 through the conveying channel 13 for production, realizing the production of cold-rolled products. Through this design and operation, a fast, efficient, convenient and safe switching function is realized. When producing cold-rolled products, in order to prevent the position of the transition connection channel 5 from rotating and moving to the connection point, after the transition connection channel 5 moves to the connection point, the pressing block 24 will push the sliding block 29 to move. When the sliding block 29 moves, it will push the power supply component 30 to move through the sliding rod 27. The movement of the power supply component 30 makes the conductive column 31 move into the inside of the conductor 33. The current inside the power supply component 30 flows through the conductor 33 and into the inside of the warning light, making the warning light light up. The first spring 28 pushes the sliding block 29 to reset, and then the conductive column 31 can be reset. After the transition connection channel 5 does not move to the connection point, the conductive column 31 will not enter the inside of the conductor 33. Then, it can be judged whether the transition connection channel 5 has moved to the connection point through the warning light, which is convenient for the transition connection channel 5 to convey the steel plate. When the galvanizing of the steel plate is completed, the third telescopic rod 36 works to push the square frame 37 to move. The square frame 37 moves the galvanized steel plate out of the inside of the zinc liquid through the rotating roller 38. The output end of the drive motor 40 rotates to drive the rotating roller 38 to rotate. When the rotating roller 38 rotates, the galvanized steel plate moves into the inside of the electromagnetic induction heater 4 for heat treatment. When the square frame 37 moves, the output end of the micro motor 42 rotates to drive the fan blade 34 to rotate. The fan blade 34 rotates to stir the zinc liquid, which can prevent the generation of zinc liquid precipitates. At the same time, after the fan blade 34 is completely separated from the zinc liquid, the fan blade 34 rotates to generate wind, and the wind can remove the zinc liquid adsorbed on the outer wall of the square frame 37.
