DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0023] Example 1

[0024] A lifting mechanism for steel production and processing, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes a mounting base 1, a first winding wheel 2, a first motor 3, a first pull rope 4, a rotating base 5, a rotating shaft 11, a gear 12, a second motor 13 and a gear ring 14. The mounting base 1 is rotatably connected to the first winding wheel 2, the first motor 3 is installed on the right side of the mounting base 1, and the output shaft on the left side of the first motor 3 is connected to the first winding wheel 2 through a coupling. The first pull rope 4 is wound on the first winding wheel 2, and the rotating base 5 is rotatably connected to the bottom of the mounting base 1. The movable end of the first pull rope 4 passes through the rotating base 5. The first pull rope 4 is rotated to the bottom of the mounting base 1. The movable end of the rope 4 is provided with a clamping assembly for fixing the steel, the rotating shaft 11 is rotatably connected to the front side of the bottom wall of the mounting base 1, the gear 12 is fixed to the lower side of the rotating shaft 11, the second motor 13 is installed on the front side of the mounting base 1, and the output shaft on the lower side of the second motor 13 is connected to the rotating shaft 11 through a coupling, the ring gear 14 is fixed to the upper part of the rotating base 5, the gear 12 is engaged with the ring gear 14, and the rotating base 5 is provided with a connecting assembly for connecting it to the first clamping plate 6, and the bottom of the mounting base 1 is provided with an arc-shaped slide groove for fitting with the rotating base 5.

[0025] like Figure 2 and Figure 3 As shown, it also includes a clamping assembly, which includes a first clamping plate 6, a second clamping plate 7, a mounting rod 8, an electric push rod 9 and a guide seat 10. The first clamping plate 6 is fixedly connected to the movable end of the first pull rope 4. There are four second clamping plates 7. The two second clamping plates 7 that are symmetrical front and back are respectively rotatably connected to the left and right sides of the first clamping plate 6. The outer sides of the four second clamping plates 7 are fixed with mounting rods 8. The left and right parts of the upper side of the first clamping plate 6 are both installed with electric push rods 9. The guide seat 10 is connected between the telescopic parts on the upper sides of the two electric push rods 9, and the mounting rod 8 and the guide seat 10 are both slidably connected.

[0026] like Figure 4 and Figure 5As shown, a connecting assembly is also included, which includes a third motor 131, a second winding wheel 15, a second pull rope 16 and a transmission assembly 17. The third motor 131 is installed on the front right side of the rotating base 5. There are two second winding wheels 15, and the second winding wheels 15 are rotatably connected to the left and right parts of the rotating base 5 respectively. The output shaft on the rear side of the third motor 131 is connected to the second winding wheel 15 on the right through a coupling. The two second winding wheels 15 are both wound with a second pull rope 16. The movable ends of the two second pull ropes 16 pass through the rotating base 5 and are fixed to the first clamping plate 6. A transmission assembly 17 is connected between the rear sides of the two second winding wheels 15. The transmission assembly 17 consists of two pulleys and a flat belt. The two pulleys are respectively fixed to the rear sides of the left and right second winding wheels 15, and a flat belt is wound around the two pulleys.

[0027] First, the device is installed on the crane. Then, the left and right electric push rods 9 are controlled to drive the guide seat 10 to move upward, thereby turning the second clamping plate 7 upward and opening through the mounting rod 8. Then, the first motor 3 and the third motor 131 are controlled to drive the first winding wheel 2 and the second winding wheel 15 on the right to reverse at the same time. The second winding wheel 15 on the left is also reversed through the transmission assembly 17, so that the first pull rope 4 and the second pull rope 16 are released synchronously. Under the action of gravity, the first pull rope 4 and the second pull rope 16 will drive the clamping assembly to move downward. When the first clamping plate 6 moves downward to contact with the steel, the electric push rod 9 is controlled to turn the first motor 3 and the third motor 131 to turn the first winding wheel 2 and the second winding wheel 15 on the right to reverse at the same time. The dynamic push rod 9 drives the guide seat 10 to move downward, thereby causing the second clamping plate 7 to flip inward and close through the mounting rod 8. The second clamping plates 7 on the left and right sides will cooperate with the first clamping plate 6 to clamp the left and right ends of the steel. Then, the first motor 3 and the third motor 131 are controlled to drive the first winding wheel 2 and the second winding wheel 15 on the right to rotate forward at the same time, so that the first winding wheel 2 and the second winding wheel 15 will synchronously reel in the first pull rope 4 and the second pull rope 16. The first pull rope 4 and the second pull rope 16 will drive the steel to move upward through the clamping assembly, and the steel will be lifted immediately. Then, the crane is controlled to move the steel to the destination.

[0028] When the steel needs to be deflected, the second motor 13 can be controlled to drive the rotating shaft 11 and the gear 12 to rotate, thereby driving the rotating seat 5 to rotate through the ring gear 14, and then driving the clamping assembly and the steel to deflect through the second pull rope 16. When the steel is deflected to an appropriate level, according to the above steps, the first motor 3 and the third motor 131 are controlled to reverse at the same time, so that the first pull rope 4 and the second pull rope 16 are released, that is, the steel is placed at the destination, and then the electric push rod 9 is continued to be controlled to drive the guide seat 10 to move upward. The second clamping plate 7 is flipped open outward, and the first motor 3 and the third motor 131 are controlled to reel in the first pull rope 4 and the second pull rope 16, so that the clamping member is away from the steel, and the lifting of the steel is completed. In summary, the clamping assembly is first used to fix the steel, and then the first pull rope 4 and the two second pull ropes 16 are used to fix the first clamping plate 6, so that the steel is not easy to rotate during lifting, and then the rotating shaft 11, the gear 12, and the gear ring 14 are used to make the adjustment of the orientation of the steel more convenient, thereby improving the flexibility during processing or transportation.

[0029] Example 2

[0030] On the basis of Example 1, Figure 1 、 Figure 6 and Figure 7 As shown, it also includes an electric guide rail 18, a slider 19 and a positioning plate 20. The electric guide rail 1 is installed on the first clamping plate 6. There are two sliders 19. The sliders 19 are respectively slidably connected to the left and right parts of the electric guide rail 18. The positioning plates 20 are fixed to the sides of the sliders 19 that are away from each other.

[0031] Initially, the electric guide rail 18 is controlled to drive the slider 19 to move outward, so that the positioning plate 20 is separated to the outside. When the first clamping plate 6 moves downward to contact the steel, the electric guide rail 18 can be controlled to drive the slider 19 to move inward, thereby driving the positioning plate 20 to move inward. The positioning plate 20 moving inward will gradually approach the left and right sides of the steel. As the positioning plate 20 continues to move inward, the positioning plate 20 that first contacts the steel will push it toward the center line direction of the first clamping plate 6 until the positioning plates 20 on the left and right sides contact the left and right sides of the steel. At this time, the center of gravity of the steel and the direction of the resultant force of the pull rope are in a vertical line. Continue to control the clamping assembly to clamp the left and right ends of the steel. In summary, by using the electric guide rail 18, the slider 19, and the positioning plate 20, the direction of the resultant force of the pull rope is in the vertical line of the center of gravity of the steel component, which can ensure the safety and stability of the lifting operation and avoid accidents.
