Description

Technical Field

[0001] This utility model relates to the field of cranes, specifically to an intelligent crane for lifting steel coils. Background Technology

[0002] Steel coils, also known as rolled steel, are formed by hot or cold pressing of steel into coils for easy storage and transportation, facilitating various processing steps such as processing into steel plates, steel strips, and other steel products. For production convenience, factories install lifting equipment to move steel coils. This equipment includes bridge cranes and gantry cranes. Bridge cranes are generally used in factory buildings; the end beams move the coils back and forth, while the trolley moves left and right along the main beam. Modern steel coil lifting devices sometimes use grippers to hook onto the through-holes of the coil. However, when moving at heights, the wire rope can easily swing, causing the lifting device to swing as well, potentially resulting in the coil rolling. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an intelligent crane specifically designed for lifting steel coils.

[0004] The technical solution of this utility model is implemented as follows: An intelligent steel coil hoisting crane includes two end beams. Two main beams are fixedly connected at the top between the two end beams, and each main beam is equipped with a track. A trolley frame travels on the track at the top of the two main beams. The two trolley frames are connected by a trolley beam. A trolley plate is installed on the top of the two trolley beams. Both ends of the trolley frame are equipped with traveling wheels. A traveling wheel axle is connected between the two traveling wheels at the front. The two opposite ends of the two traveling wheel axles are fixed to a dual-output shaft reduction motor. Two winches are installed on the top of the trolley plate. Steel wire ropes are wound on the winches. The steel wire ropes are wound on pulleys. The pulleys are installed on pulley frames. The pulley frames are installed on both sides of the top of a horizontal beam. A steel coil lifting device is installed at the bottom of the horizontal beam through a rotating mechanism.

[0005] The steel coil lifting device includes a lifting beam, which is a hollow structure open at both ends. Telescopic arms are slidably mounted on both ends of the lifting beam. A vertical arm is fixedly connected to the end of the telescopic arm, and a horizontal arm is fixedly connected to the bottom of the vertical arm. The two horizontal arms are arranged opposite each other. A support device is provided at the bottom of the vertical arm. A mounting base is fixedly mounted on the bottom of the lifting beam. Horizontal hydraulic cylinders are fixedly connected to the two opposite sides of the mounting base. The free end of the horizontal hydraulic cylinder is fixedly connected to the inner side of the adjacent vertical arm.

[0006] The rotating device includes a turntable bearing 1 located at the bottom of the horizontal beam. The top of the inner ring of the turntable bearing 1 is fixedly connected to the bottom of the horizontal beam, and the bottom of the outer ring gear of the turntable bearing 1 is fixedly connected to the top of the lifting beam. The outer ring gear of the turntable bearing 1 meshes with a drive gear 1, which is driven by a drive motor 1.

[0007] The support device includes a rotating arm, which is rotatably mounted at the bottom of a horizontal arm. A telescopic arm is fitted over the rotating arm. Both the rotating arm and the telescopic arm are hollow structures. A hydraulic cylinder is fixedly connected inside the rotating arm, and a support arm is fixedly connected to the bottom of the hydraulic cylinder.

[0008] A turntable bearing is fixedly installed between the vertical arm and the rotating arm. The top of the inner ring of the turntable bearing is fixedly connected to the bottom of the horizontal arm, and the bottom of the outer ring gear of the turntable bearing is fixedly connected to the top of the rotating arm. The outer ring gear of the turntable bearing meshes with a drive gear, which is connected to a drive motor.

[0009] The two ends of the trolley plate extend to the outside of the main beam. The bottom of the trolley plate, located on the outside of the two main beams, is fixedly connected to the fixed end of the vertically installed telescopic column. The movable end of the telescopic column is fixedly connected to the top of the horizontal beam. The telescopic column is located on the side of the pulley frame.

[0010] The beneficial effects of this utility model are as follows: This utility model uses a rotating device to drive the steel coil lifting device to rotate, thereby changing the direction; the trolley wheels on the two main beams are connected by trolley wheel axles and driven by a dual-output shaft reduction motor, ensuring synchronization and improving safety; the telescopic column can extend and retract with the rise and fall of the wire rope, reducing the swaying of the wire rope and making the lifting more stable; the steel coil lifting device uses a telescopic arm to achieve horizontal movement of the horizontal arm to clamp the steel coil laterally, and the horizontal arm and the support arm work together to provide longitudinal support at the through hole of the steel coil, reducing the swaying of the steel coil. The support arm is driven to rotate by the rotating arm, which allows the horizontal arm to enter the through hole of the steel coil first, avoiding interference from the support arm.

Detailed Implementation

[0015] like Figure 1-3 As shown, an intelligent steel coil hoisting crane includes two end beams 1. Two spaced main beams 2 are fixedly connected to the top of the two end beams 1. Each main beam 2 has a track. A trolley frame 3 travels on the track at the top of the two main beams 2. The two trolley frames 3 are connected by a trolley beam 21. The two opposite ends of the two trolley frames 3 are fixedly connected to the trolley beam 21. A trolley plate 4 is installed on the top of the two trolley frames 21. Both ends of the trolley frames 3 are equipped with traveling wheels 23. A traveling wheel axle connects the two traveling wheels 23 at the front. The two opposite ends of the two traveling wheel axles are fixed to a dual-output shaft reduction motor 25. Two winches 26 are installed on the top of the trolley plate 4. Steel wire ropes are wound around each winch 26. The steel wire ropes are wound around pulleys, which are mounted on pulley frames. The pulley frames are installed on both sides of the top of a horizontal beam 27. A steel coil lifting device is installed at the bottom of the horizontal beam 27 via a rotating mechanism.

[0016] Specifically, the two drive shafts of the two winches 26 are connected to the opposite ends of the drive shaft. The two connecting shafts are driven by a dual-output shaft reduction motor, which simultaneously drives the two winches 26 to work, ensuring the synchronicity of the steel coil lifting.

[0017] The steel coil lifting device 5 includes a lifting beam 6, which is a hollow structure with open ends. Telescopic arms 7 are slidably arranged at both ends of the lifting beam 6. A vertical arm 8 is fixedly connected to the end of the telescopic arm 7. A horizontal arm 9 is fixedly connected to the bottom of the vertical arm 8. The two horizontal arms 9 are arranged opposite to each other. A support device is provided at the bottom of the vertical arm 8. A mounting base 19 is fixedly attached to the bottom of the lifting beam 6. Horizontal hydraulic cylinders 20 are fixedly connected to the two opposite sides of the mounting base 19. The free end of the horizontal hydraulic cylinder 20 is fixedly connected to the inner side of the adjacent vertical arm 8.

[0018] Specifically, the dual-output shaft geared motor 25 starts and drives the two traveling wheels 23 on the two tracks to move synchronously. The winch 26 starts and drives the wire rope to rise and fall, which in turn drives the steel coil lifting device 5 to rise above the steel coil. The two horizontal arms 9 are located on both sides of the opening of the steel coil. The horizontal hydraulic cylinder 20 starts and drives the horizontal arms 9 to move inward and enter the opening of the steel coil, so that the two horizontal arms 9 hook the steel coil. Then the winch 26 is started to lift the steel coil and transport it to another place.

[0019] The rotating device includes a turntable bearing 28 located at the bottom of the horizontal beam 27. The top of the inner ring of the turntable bearing 28 is fixedly connected to the bottom of the horizontal beam 27, and the bottom of the outer ring gear of the turntable bearing 28 is fixedly connected to the top of the lifting beam 6. The outer ring gear of the turntable bearing 28 meshes with a drive gear 29, which is driven by a drive motor 30. Specifically, the rotating device can rotate the steel coil lifting device to achieve the direction of the steel coil. The drive motor 30 is fixedly installed on the top of the horizontal beam, and the shaft of the drive motor 30 passes vertically through the horizontal beam. When the drive motor 30 starts, it drives the drive gear 29 to rotate, and the outer ring gear of the turntable bearing 28 meshing with the drive gear 29 rotates, thereby driving the lifting beam 6 to rotate.

[0020] The supporting device includes a rotating arm 10, which is rotatably mounted at the bottom of the vertical section. A telescopic arm 17 is fitted around the rotating arm 10. Both the rotating arm 10 and the telescopic arm 17 are hollow structures. A hydraulic cylinder 16 is installed between the rotating arm 10 and the telescopic arm 17. The fixed end of the hydraulic cylinder 16 is fixedly connected to the bottom of the interior of the rotating arm 10, and the bottom of the free end of the hydraulic cylinder 16 is fixedly connected to the top of the interior of the telescopic arm 17. The hydraulic cylinder 16 is fixedly connected inside the rotating arm 10, and a support arm 11 is fixedly connected to the bottom of the telescopic arm 17. Specifically, during lifting, the two support arms 11 are rotated to opposite positions. After the horizontal arm 9 is inserted into the steel coil, the rotating arm 10 rotates, causing the horizontal arm 9 to rotate, so that the two horizontal arms 9 are opposite each other and located at the through hole of the steel coil. Then, the hydraulic cylinder 16 is activated to drive the telescopic arm 17 to rise and drive the support arm 11 to fall, so that the bottom of the support arm 11 abuts against the bottom of the through hole of the steel coil, thereby reducing the rotation of the steel coil.

[0021] A turntable bearing 13 is fixedly installed between the vertical arm 8 and the rotating arm 10. The top of the inner ring of the turntable bearing 13 is fixedly connected to the bottom of the vertical arm 8, and the bottom of the outer ring gear of the turntable bearing 13 is fixedly connected to the top of the rotating arm 10. The outer ring gear of the turntable bearing 13 meshes with a drive gear 14, and the drive gear 14 is connected to the drive motor 15.

[0022] The two ends of the trolley plate 4 extend to the outside of the main beam 2. The bottom of the trolley plate 4 and the outside of the two main beams 2 are fixedly connected to the fixed end of the vertically arranged telescopic column 18. The movable end of the telescopic column 18 is fixedly connected to the top of the horizontal beam 27. Specifically, when the winch 26 drives the wire rope to rise and fall, the free end of the telescopic column 18 also rises and falls with it, which can reduce the swing of the wire rope and make it more stable when in action.
