[0028] Referring to Figures 1-3 , the present utility model provides a lifting sling for large flat ingots, including:

[0029] A lifting block 1, a lifting ear 2 is fixedly connected to the top surface of the lifting block 1, a connecting shaft 3 is vertically rotatably connected to the bottom of the lifting block 1, and the bottom end of the connecting shaft 3 is fixedly connected to a cross plate 4, and the cross plate 4 is vertically arranged with the connecting shaft 3;

[0030] A clamping mechanism, the clamping mechanism includes clamping arms symmetrically and slidably connected to the cross plate 4, the clamping arms include clamping plates 5 arranged vertically, on the sides of the two clamping plates 5 away from each other, inclined rods 6 are respectively fixedly connected, the bottom end of the inclined rod 6 is fixedly connected to the bottom end of the clamping plate 5, the top end of the inclined rod 6 is horizontally slidably connected to the cross plate 4 through a sliding component, and an included angle is provided between the inclined rod 6 and the clamping plate 5;

[0031] A pushing component, the pushing component is slidably connected to the cross plate 4, and the pushing component is used to push the two clamping arms to move in opposite directions;

[0032] A rotation driving component, the rotation driving component is installed on the lifting block 1, and the rotation driving component is used to drive the connecting shaft 3 to rotate;

[0033] Wherein, friction blocks 7 are installed at the bottom ends of the sides of the two clamping plates 5 close to each other.

[0034] When the present utility model is used, the device is connected to the lifting equipment through the lifting ear 2, the sling is moved to the designated position through the lifting equipment, and then the relative angle of the sling is adjusted through the rotation driving component. The sling drops, the pushing component pushes the two clamping arms to move towards each other to clamp the workpiece, and then the lifting equipment moves the workpiece to the designated working station, and the pushing component controls the two clamping arms to release the workpiece to complete the transfer work of the workpiece.

[0035] In the present utility model, the workpiece is clamped through the cooperation of the inclined rod 6 and the clamping plate 5, and the force application points are mainly concentrated at the bottom position of the clamping plate 5 to ensure the stability of clamping and provide the safety of the device.

[0036] For a further optimized solution, a horizontal chute 8 is provided on the bottom surface of the cross plate 4, and a through groove is provided on one side of the horizontal chute 8. The sliding assembly includes a sliding rod 9 fixedly connected in the horizontal chute 8. The cross-sectional shape of the sliding rod 9 is rectangular. The top ends of the inclined rods 6 and the top ends of the clamping plates 5 are respectively fixedly connected with sliders 10. The sliders 10 are slidably matched with the horizontal chute 8. The sliders 10 are slidably connected to the sliding rod 9. A sliding sleeve 11 is fixedly connected between the two sliding rods 9. The sliding sleeve 11 is sleeved on the sliding rod 9. The inclined rods 6 and the clamping plates 5 are slidably connected to the horizontal chute 8. One side of the slider 10 at the top end of the inclined rod 6 is fixedly connected with a connecting rod, and the connecting rod is correspondingly arranged with the pushing assembly.

[0037] For a further optimized solution, the pushing assembly includes an installation ring 12. A push plate 13 is vertically and fixedly connected to one side of the installation ring 12. The two push plates 13 are arranged opposite to and parallel to each other. The two push plates 13 are respectively slidably matched with the front and rear sides of the cross plate 4. Oblique grooves 14 are symmetrically provided on the push plate 13 opposite to the through groove. One end of the connecting rod is slidably connected in the oblique groove 14. The two oblique grooves 14 are arranged in a shape of an eight-character structure. A hydraulic telescopic rod 15 is fixedly connected to the side surface of the hanging block 1. The bottom end of the hydraulic telescopic rod 15 is slidably connected to the side of the installation ring 12 away from the push plate 13. During use, the push plate 13 is pushed downward or upward by the hydraulic telescopic rod 15. The connecting rod on the slider 10 at the top end of the inclined rod 6 moves along the direction of the oblique groove 14, so as to realize the left and right movement of the clamping arm. At the same time, since the main force-applying part is on the inclined rod 6, most of the thrust of the push plate 13 is transmitted to the bottom of the clamping plate 5 through the inclined rod 6, and part of the force is transmitted to the slider 10 at the top of the clamping plate 5 through the sliding sleeve 11. Therefore, the relative stability of the clamping between the friction block 7 and the workpiece is ensured, and the safety of the device is ensured. At the same time, the hydraulic telescopic rod 15 and the installation ring 12 rotate relative to each other, which is convenient for the rotation of the bottom clamping mechanism. The outer diameter of the installation ring 12 is larger than the diameter of the hanging block 1.

[0038] For a further optimized solution, a limiting block 16 is fixedly connected to one side of the push plate 13. The cross-sectional shape of the limiting block 16 is an isosceles trapezoid. A limiting groove is provided on the side surface of the cross plate 4. The limiting block 16 and the limiting groove are in limiting cooperation. The connection relationship between the push plate 13 and the cross plate 4 can be ensured through the arrangement of the limiting block 16 and the limiting groove, and the push plate 13 is prevented from detaching from the cross plate 4.

[0039] For a further optimized solution, the rotation driving assembly includes a driven gear 17 coaxially and fixedly connected to the connecting shaft 3. A driving motor 18 is fixedly connected to the bottom surface of the hanging block 1. The output shaft of the driving motor 18 is fixedly connected with a driving gear 19. The driving gear 19 meshes with the driven gear 17. The driving motor 18 is used to control the rotation of the driving gear 19. The driving gear 19 drives the driven gear 17 to rotate, so as to drive the lower clamping mechanism to rotate. At the same time, the diameter of the driving gear 19 needs to be smaller than the diameter of the driven gear 17 to form a speed reduction effect.

[0040] For a further optimized solution, a T-shaped groove is provided at the center of the bottom surface of the hanging block 1. The top end of the connecting shaft 3 is fixedly connected to a turntable 20, and the turntable 20 is rotatably connected in the T-shaped groove. A ball 21 is provided between the bottom surface of the turntable 20 and the T-shaped groove. The arrangement of the turntable 20 and the ball 21 can reduce the relative friction between the mounting shaft and the hanging block 1 and improve the service life of the device.

[0041] For a further optimized solution, a compression spring 22 is fixedly connected between the side surface of the inclined rod 6 and the side wall of the horizontal chute 8. The compression spring 22 is sleeved on the sliding rod 9. The compression spring 22 is always in a compressed state, and cooperates with the push plate 13 to push the slider 10, so as to drive the clamping plate 5 to hold the workpiece.

[0042] For a further optimized solution, a pressure sensor 23 is installed on the friction block 7. The arrangement of the pressure sensor 23 can detect the relative pressure between the friction block 7 and the workpiece, so as to facilitate lifting the workpiece.
