Description

Technical Field

[0001] This utility model relates to the field of crane production equipment technology, and in particular to a material guiding device for an uncoiler. Background Technology

[0002] Crane manufacturing requires a large amount of steel plates. To facilitate storage and transportation, steel plates are often hot-pressed or cold-pressed into coils. When needed, they are uncoiled, leveled, and then processed into the required profiles. Specifically, during uncoiling, the coiled steel is placed on a guide device, which then transports the coiled steel to the uncoiler to complete the uncoiling process. Currently, most existing guide devices are horizontal to the uncoiler. However, the steel coils are relatively large, causing the top of the coil on the guide device to be higher than the operator's height. This makes it difficult for the operator to visually observe the state of the coil on the guide device, increasing the difficulty of adjusting the distance between the guide device and the coil.

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] A feeding device for an uncoiler, such as Figures 1-6 As shown, the device includes a frame 1, which is a hollow structure with openings at both ends. A steel plate enters through one opening of the frame 1, passes through the hollow structure of the frame 1, and is then conveyed to an uncoiler through the other opening for uncoiling. The frame 1 is fixedly connected to the ground. A material guiding assembly is installed on the frame 1 to guide the steel plate. A pit 2 is formed in the ground on the side of the frame 1 away from the uncoiler. A conveying trench 3 corresponding to the material guiding assembly is formed in the pit 2. A horizontal conveying device is installed in the conveying trench 3. The movable conveying assembly has clamping assemblies installed at the bottom of the pits 2 on both sides of the conveying trench 3; a bridge 4 is installed above the pit 2, and the bridge 4 is located on the side of the clamping assembly away from the frame 1. The side of the pit 2 away from the clamping assembly is a steel coil storage area; the clamping assembly includes a mounting base 5, a mounting plate 6 is slidably connected to the mounting base 5, a horizontally arranged mounting shaft 7 is fixedly connected to the top of the mounting plate 6, the mounting shaft 7 extends to the outside of the mounting plate 6 near the conveying trench 3, and a ring-shaped abutment plate 8 is fixedly connected to the mounting shaft 7 along its circumference. In operation, the conveying assembly moves to the steel coil storage area, where a crane places the steel coil onto the conveying assembly. The conveying assembly then transports the steel coil to the conveying groove 3 below the clamping assembly. Next, the clamping plates 8 of the two clamping assemblies approach each other, causing the mounting shaft 7 to be inserted into the hollow hole of the steel coil, with the clamping plates 8 contacting both ends of the coil. The steel coil rotates under the action of the guiding assembly, causing the steel plate at the end of the coil to enter the uncoiler via the frame 1. Under the combined action of the uncoiler's drag and the guiding assembly, the steel plate on the coil is continuously transported into the uncoiler for uncoiling. The pit 2 allows the steel coil to be placed below ground level, enabling operators to observe the coil and guiding assembly from the ground and adjust the guiding assembly to ensure smooth material handling. The bridge 4 facilitates operator passage and provides an optimal observation position. The conveying assembly facilitates underground transport of the steel coil, reducing the dangers associated with overhead crane lifting.

[0026] In another embodiment, guide rails 9, arranged along the length of the mounting base 5, are fixedly connected to both sides of the mounting base 5. The mounting plate 6 is slidably connected to the guide rails 9. A movable cylinder 10 is fixedly connected to the mounting base 5, and the piston rod end of the movable cylinder 10 is fixedly connected to the mounting plate 6. The movable cylinder 10 facilitates the adjustment of the position of the mounting plate 6, thereby facilitating the adjustment of the distance between the two clamping plates 8 to achieve the clamping of the steel coil. The guide rails 9 improve the sliding stability between the mounting base 5 and the mounting plate 6.

[0027] In another embodiment, a conveying trolley 11 with a drive component is installed inside the conveying trench 3. A traveling wheel 12 is rotatably connected to the conveying trolley 11. A base 13, arranged along the length of the conveying trench 3, is fixedly connected to each of the two inner sidewalls of the conveying trench 3. I-beam rails are fixedly connected to the base 13, and the traveling wheel 12 is rotatably connected to the corresponding I-beam rails. A support frame 14 for supporting the steel coil is installed on the top of the conveying trolley 11. Two spaced-apart support rollers 15 are rotatably connected to the support frame 14. The support rollers 15 are horizontally positioned, and their central axes along the length of the support rollers are perpendicular to the central axis of the conveying trench 3 along the length of the trench. The bottom of the conveying trolley 11 is spaced apart from the bottom of the base 13 and the conveying trench 3. In use, under the action of the drive component, the traveling wheel 12 rotates along the I-beam rails, thereby moving the conveying trolley 11. The conveying trolley 11 drives the support frame 14 and the steel coil located on the support frame 14 to move. The support rollers 15 improve the stability of the support frame 14 in supporting the steel coil and reduce the slippage of the steel coil.

[0028] In another embodiment, the driving component includes a conveyor motor 16, which is fixedly connected to the conveyor trolley 11. The output shaft of the conveyor motor 16 is fixedly connected to a sprocket 17. One of the traveling wheels 12 of the conveyor trolley 11 is coaxially connected to a driving wheel 18. The sprocket 17 and the driving wheel 18 are connected by a transmission chain. In use, when the conveyor motor 16 is started, the output shaft of the conveyor motor 16 drives the sprocket 17 to rotate. The sprocket 17 drives the driving wheel 18 to rotate through the transmission chain. Since the driving wheel 18 is coaxially connected to the traveling wheel 12, it drives the traveling wheel 12 to rotate, thereby realizing the movement of the conveyor trolley 11.

[0029] Two lifting hydraulic cylinders 19 are fixedly connected to the bottom of the conveying trolley 11. The fixed ends of the two lifting hydraulic cylinders 19 pass through the conveying trolley 11 and extend above it. The piston rod ends of the lifting hydraulic cylinders 19 are fixedly connected to the bottom end of the support frame 14. In use, when the conveying trolley 11 moves into the conveying groove 3 below the clamping assembly, the lifting hydraulic cylinders 19 are activated. The piston rod ends of the lifting hydraulic cylinders 19 drive the support frame 14 to move upward. The support frame 14 drives the steel coil to move upward until the center hole of the steel coil is close to the center axis of the mounting shaft 7. Then, the lifting hydraulic cylinders 19 are closed, and the moving cylinder 10 is activated. The piston rod ends of the moving cylinder 10 drive the two mounting shafts 7 to move closer to each other. Both mounting shafts 7 are inserted into the center hole of the steel coil until the abutment plate 8 abuts against both sides of the steel coil. Then, the moving hydraulic cylinder is closed, completing the clamping of the steel coil by the clamping assembly. The lifting hydraulic cylinder 19 facilitates the adjustment of the height of the support frame 14, thereby adjusting the height of the steel coil located on the support frame 14. This allows the height of the steel coil to be adapted to the height of the mounting shaft 7 and the clamping plate 8, avoiding the cumbersome operation of using a crane to lift the steel coil during clamping, and improving the convenience and safety of operation.

[0030] In another embodiment, the material guiding assembly includes a material guiding hydraulic cylinder 20. The fixed end of the material guiding hydraulic cylinder 20 is hinged to the top of the frame 1. A connecting member 21 is hinged to the piston rod end of the material guiding hydraulic cylinder 20. The connecting member 21 extends to the side of the frame 1 near the clamping assembly. Two spaced-apart fixed plates 22 are fixedly connected to the bottom of the end of the connecting member 21 away from the frame 1. At least one material guiding roller 23 is rotatably connected between the two fixed plates 22. In this embodiment, there are two material guiding rollers 23. A drive assembly for driving the material guiding rollers 23 is also installed on the connecting member 21. In use, the material guiding hydraulic cylinder 20 is adjusted so that the bottom of the material guiding roller 23 abuts against the steel coil. Then, the drive assembly is started, and the drive assembly drives the material guiding roller 23 to rotate, thereby realizing the conveying of the steel plate.

[0031] In another embodiment, the drive assembly includes a guide motor 24, which is fixedly connected to the connector 21. A drive sprocket 25 is drivenly connected to the output shaft of the guide motor 24. A driven sprocket 26 is rotatably connected to the outer wall of one of the fixed plates 22. The drive sprocket 25 and the driven sprocket 26 are connected by a chain drive. A pinion 27 coaxially arranged with the driven sprocket 26 is rotatably connected to the mounting plate 6. Both the driven sprocket 26 and the pinion 27 are fixedly connected to the connecting shaft. A transmission gear 28 meshing with the pinion 27 is also rotatably connected to the mounting plate 6. Two driven gears 29 meshing with the transmission gears 28 are installed at the lower part of the mounting plate 6. Both driven gears 29 are coaxially arranged with the guide roller 23. In use, the guide motor 24 is started, and the output shaft of the guide motor 24 drives the drive sprocket 25 to rotate. The drive sprocket 25 drives the driven sprocket 26 to rotate via a chain. The driven sprocket 26 drives the small gear 27 coaxial with it to rotate. The small gear 27 drives the transmission gear 28 meshing with it to rotate. The transmission gear 28 then drives the two driven gears 29 to rotate. Since the two driven gears 29 are fixedly connected to the connecting shaft of their corresponding guide rollers 23, the two driven gears 29 drive the corresponding guide rollers 23 to rotate, thereby realizing the conveying of the steel plate.

[0032] In another embodiment, a pressing hydraulic cylinder 30 is fixedly connected to the connecting member 21 between the guide roller 23 and the frame 1. The central axis of the pressing hydraulic cylinder 30 along its length is perpendicular to the central axis of the connecting member 21 along its length. A pressing tongue 31 is fixedly connected to the piston rod end of the pressing hydraulic cylinder 30, and the pressing tongue 31 is located below the connecting member 21. Because the steel plate is wound on the steel coil for a long time, the steel coil output by the guide roller 23 will tilt towards the connecting member 21. The pressing tongue 31 facilitates pressing down the tilted steel plate, allowing the steel coil to pass smoothly through the guiding device and reducing the phenomenon of the tilted steel coil rubbing against the connecting member 21 and other components. The pressing hydraulic cylinder 30 also facilitates the adjustment of the height of the pressing tongue 31, ensuring that the pressing tongue 31 always contacts the steel plate, thus improving the practicality of the device.

[0033] In another embodiment, a placement assembly is also installed on the frame 1 below the material guiding assembly. The placement assembly includes a placement plate 32, one end of which extends into the frame 1 and is hinged to it. A placement hydraulic cylinder 33 is hinged to the bottom of the placement plate 32, and the fixed end of the placement hydraulic cylinder 33 is hinged to the frame 1. The placement plate 32 facilitates the placement of the steel plate guided by the material guiding assembly onto it, preventing the steel plate from being suspended in mid-air. The placement hydraulic cylinder 33 allows for adjustment of the angle of the placement plate 32, enabling it to adapt to different states of the steel coil and improving the adaptability of the device.

[0034] In another embodiment, the placement plate 32 has an opening at one end away from the frame 1, and the placement plate 32 has a hollow structure. An extension plate 34 is slidably connected inside the placement plate 32. An extension hydraulic cylinder (not shown in the figure) is installed at the end of the extension plate 34 near the frame 1, and the fixed end of the extension hydraulic cylinder is connected to the placement plate 32. In use, when the extension hydraulic cylinder is activated, the piston rod of the extension hydraulic cylinder extends, and the piston rod end of the extension hydraulic cylinder drives the extension plate 34 to move outward from the placement plate 32, thereby facilitating the lengthening of the placement plate 32 to improve the adaptability of the device.

[0035] In another embodiment, a transition plate 35, parallel to the placement plate 32, is slidably connected to the top of the placement plate 32. The transition plate 35 abuts against the placement plate 32, and the end of the transition plate 35 away from the frame 1 is fixedly connected to the end of the extension plate 34 near the clamping assembly. The transition plate 35 improves the stability of the extension plate 34 during sliding and allows the steel plate to fall from the higher transition plate 35 onto the lower placement plate 32, preventing the steel plate from moving from the lower extension plate 34 to the higher placement plate 32, thus ensuring smooth movement of the steel plate.

[0036] Instructions for use: Start the conveyor motor 16. The conveyor motor 16 drives the conveyor trolley 11 to move to the steel coil storage area. The steel coil is placed on the support frame 14 by the crane. Then, when the conveyor trolley 11 moves into the conveying groove 3 below the clamping assembly, start the lifting hydraulic cylinder 19. The piston rod end of the lifting hydraulic cylinder 19 drives the support frame 14 to move upward. The support frame 14 drives the steel coil to move upward until the center hole of the steel coil is close to the center axis of the mounting shaft 7. Then, close the lifting hydraulic cylinder 19 and start the moving cylinder 10. The piston rod end of the moving cylinder 10 drives the two mounting shafts 7 to move closer to each other. Both mounting shafts 7 are inserted into the center hole of the steel coil until the abutment plate 8 abuts against both sides of the steel coil. Then, close the moving cylinder 10 to complete the clamping of the steel coil by the clamping assembly. Then, the placement hydraulic cylinder 33 is adjusted to adjust the angle of the placement plate 32 so that the end of the steel coil can be placed on the placement plate 32. The extension hydraulic cylinder is adjusted so that the extension plate 34 is close to the steel coil. At the same time, the guide hydraulic cylinder 20 is adjusted so that the guide roller 23 abuts against the steel coil. The guide motor 24 is started. The guide motor 24 drives the guide roller 23 to rotate through the drive assembly. The pressing hydraulic cylinder 30 is started. The piston rod of the pressing hydraulic cylinder 30 extends and makes the pressing tongue 31 abut against the steel plate. After the pressing tongue 31 is pressed down, the steel coil falls on the placement plate 32 and is conveyed to the uncoiler through the frame 1.
