[0034] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0035] Embodiment 1:

[0036] Reference Figure 1 and Figure 2The present embodiment provides a lifting device for flipping plate-type workpieces, comprising a support portion 1, two flipping portions 2 and two clamping portions 3, wherein the upper portion of the support portion 1 is used to connect the lifting equipment, and the lower portion is provided with a first opening 11 downward to form a clamping space, and the clamping space provides a space for clamping and flipping the workpiece 4 to be flipped at the same time. The support portion 1 can be in a triangular shape, a bell shape, etc., depending on whether the aforementioned functions can be achieved. Specifically, the two flipping portions 2 are coaxially connected to the lower portion of the support portion 1 one by one and are located in the first opening 11, and the axes of the two flipping portions 2 are parallel to the first horizontal direction a, and the first horizontal direction a is the width direction of the support portion 1. The two clamping portions 3 are arranged one by one at the opposite ends of the two flipping portions 2 along the first horizontal direction a, and the two clamping portions 3 relatively clamp the workpiece 4 to be flipped along the first horizontal direction a at the first opening 11, so that the workpiece 4 to be flipped is flipped around its axis through the clamping portion 3 along the flipping portion 2.

[0037] Among them, the support part 1 is used to connect the lifting equipment on the one hand to provide lifting power for the sling, and on the other hand to provide support for the workpiece to be flipped 4. During the flipping process, the two clamping parts 3 clamp the workpiece to be flipped 4, and then rotate horizontally and coaxially relative to the support part 1 through the two flipping parts 2, thereby driving the workpiece to be flipped 4 to flip. After the workpiece to be flipped 4 is lifted, the workpiece to be flipped 4 can be flipped by manually applying a small torsional force to the workpiece to be flipped 4. The overall structure of the sling is simple, and in terms of operation, it can adapt to various working conditions.

[0038] Reference Figure 1 and Figure 2 This embodiment provides a lifting device for flipping plate-type workpieces. The flipping part 2 includes a connecting shaft 21, which is arranged along the first horizontal direction a. The first end is used to connect the clamping part 3, and the second end is connected to the supporting part 1 through a ball-axle joint to facilitate the flexible rotation of the connecting shaft 21 relative to the supporting part 1.

[0039] Reference Figure 1 and Figure 2This embodiment provides a lifting device for flipping plate-type workpieces, wherein a spherical protrusion 22 is provided at the second end of the connecting shaft 21, and a spherical groove 12 is provided at a position of the support portion 1 corresponding to the spherical protrusion 22. At least one flipping portion 2 also includes a limiter 23, or both flipping portions 2 may include a limiter 23. The limiter 23 is movably arranged on one side of the spherical groove 12 along the second horizontal direction b, and the limiter 23 can abut against or move away from the spherical protrusion 22 to limit or not limit the rotation of the spherical protrusion 22 relative to the spherical groove 12. The second horizontal direction b is perpendicular to the first horizontal direction a. During the lifting process of the workpiece 4 to be flipped, the workpiece 4 to be flipped does not need to be flipped. At this time, the limiter 23 abuts against the spherical protrusion 22 to limit the rotation of the spherical protrusion 22 relative to the spherical groove 12. When the workpiece 4 to be turned over is lifted and needs to be turned over, when the stopper 23 is away from the spherical protrusion 22, the spherical protrusion 22 can rotate relative to the spherical groove 12, and then the connecting shaft 21 rotates around its axis; the two connecting shafts 21 cooperate to drive the two clamping parts 3 to rotate, thereby realizing the turning of the workpiece 4 to be turned over. The stopper 23 is screwed to the support part 1.

[0040] Reference Figure 1 and Figure 2 This embodiment provides a lifting device for flipping plate-type workpieces. The clamping portion 3 is provided with a receiving cavity 31 facing the clamping space, which is convenient for accommodating the workpiece 4 to be flipped, so that the workpiece 4 to be flipped is relatively stable during the lifting and flipping process. Specifically, Figure 1 and Figure 3 As shown, the cross section of the accommodating cavity 31 can be triangular to match the corners of the workpiece 4 to be flipped in the form of a rectangular plate. In this case, the two clamping parts 3 clamp the workpiece 4 to be flipped at the diagonal positions of the workpiece 4 to be flipped, making the flipping process easier. Alternatively, the cross section of the accommodating cavity 31 can be quadrilateral to match the side of the workpiece 4 to be flipped in the form of a rectangular plate. The two clamping parts 3 clamp the two opposite sides of the workpiece 4 to be flipped, and the flipping of the workpiece 4 to be flipped can also be achieved.

[0041] Reference Figure 1 and Figure 2 This embodiment provides a lifting device for flipping plate-type workpieces. The support part 1 includes two connecting rods 13 hinged at the upper end. The two flipping parts 2 are correspondingly arranged at the lower ends of the two connecting rods 13.

[0042] Reference Figure 1 and Figure 2This embodiment provides a lifting device for flipping plate-like workpieces. The support portion 1 further includes a vertically arranged triangular bracket 14, which is arranged above the two connecting rods 13. The upper ends of the two connecting rods 13 are respectively hinged to the two vertex angles of the lower part of the triangular bracket 14. The upper part of the triangular bracket 14 is used to connect the lifting equipment, which plays a stable supporting role between the lifting equipment and the two connecting rods 13. At the same time, the distance between the two connecting rods 13 can be increased in the first horizontal direction a to accommodate a larger workpiece 4 to be flipped.

[0043] Reference Figure 3 , Figure 4 and Figure 5 This embodiment provides a lifting device for flipping plate-like workpieces. The support portion 1 further includes an adjusting rod 15, which is arranged on the two connecting rods 13 along the first horizontal direction a. The adjusting rod 15 can adjust the angle between the straight lines where the two connecting rods 13 are located along the first horizontal direction a to limit the size of the first opening 11 to adapt to workpieces 4 to be flipped of different sizes.

[0044] Reference Figure 3 , Figure 4 and Figure 5 This embodiment provides a lifting device for flipping plate-like workpieces, wherein the first end of the adjusting rod 15 is hinged on a connecting rod 13, and the second end is passed through another connecting rod 13. The second end of the adjusting rod 15 is provided with a plurality of limiting grooves 151 distributed along the first horizontal direction a, and the limiting grooves 151 can be engaged with or disengaged from the connecting rod 13 corresponding to the second end of the adjusting rod 15. Figure 2 For ease of operation, the limiting groove 151 opens downward, and when engaged with different limiting grooves 151, the distance between the two connecting rods 13 can be adjusted and limited according to the actual size of the workpiece 4 to be flipped.

[0045] Reference Figure 1 and Figure 2 This embodiment provides a lifting device for flipping plate-type workpieces. The lower end of the connecting rod 13 is circular, and the center of the circular lower end is located on the axis of the flipping part 2. The circular lower end can prevent the lifting device from scratching other objects during lifting and flipping, which is safer.
