[0001] This utility model relates to the field of rotary lifting equipment technology, specifically a workpiece rotary lifting equipment. Background Technology

[0002] A workpiece swivel lifting device is a device used in industrial production for lifting and transporting workpieces. It can achieve 360-degree rotation of the workpiece, making it convenient to adjust the position and angle of the workpiece during processing, assembly, inspection and other processes, thereby improving production efficiency and safety. It is commonly used in heavy lifting operations in industries such as machining, automobile manufacturing, and aerospace.

[0003] Currently, workpiece rotating lifting devices lack a limiting structure for the lifting beam, causing the beam to rotate under the force of oscillation during use. This results in instability of the beam and affects the effectiveness of the rotating lifting device. Therefore, a new workpiece rotating lifting device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a workpiece rotating lifting device, which has advantages such as improved overall stability of the rotating lifting device. It solves the problem that the lifting beam rotates when subjected to swinging forces during use, resulting in insufficient stability of the lifting beam and affecting the performance of the rotating lifting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a workpiece rotating lifting device, comprising a lifting device, a lifting ring, and a lifting plate, wherein the bottom of the lifting device is respectively provided with a rotating structure and a positioning structure;

[0006] The rotating structure includes a hanging shaft fixedly installed on the inner wall of the bottom of the hanging plate. A first bearing and a second bearing are respectively installed on the outer peripheral wall of the hanging shaft. An adjusting sleeve is fixedly installed on the outer peripheral wall of both the first bearing and the second bearing. A hanging beam is fixedly installed on the outer peripheral wall of the adjusting sleeve.

[0007] The positioning structure includes a limiting pin inserted into the inside of the lifting shaft, a pin inserted into the inside of the limiting pin, an mounting plate fixedly installed on the bottom outer wall of the lifting beam, four connecting plates fixedly installed on the bottom outer wall of the mounting plate, a rotating shaft rotatably connected between the interiors of two adjacent connecting plates, a counterweight plate fixedly installed on the outer peripheral wall of the rotating shaft, a clamping plate fixedly installed on the bottom outer wall of the counterweight plate, two limiting plates fixedly installed on the bottom outer wall of the mounting plate, and a clamping seat fixedly installed on the top of the clamping plate.

[0008] Furthermore, the first bearing includes an inner ring, an outer ring, and a first ball, with the first ball located between the inner ring and the outer ring. The inner ring is fixedly installed on the outer peripheral wall of the hanger shaft, and the outer ring is fixedly installed on the inner peripheral wall of the adjusting sleeve. The second bearing includes an upper ring, a lower ring, and a second ball, with the second ball located between the upper ring and the lower ring. The lower ring is installed on the outer peripheral wall of the hanger shaft, and the upper ring is fixedly installed on the inner peripheral wall of the adjusting sleeve.

[0009] Furthermore, the shaft has a first insertion hole inside, the limiting pin is inserted into the first insertion hole and is of the same size, the limiting pin has a second locking hole inside, and the pin is inserted into the second locking hole and is of the same size.

[0010] Furthermore, a U-shaped slot is provided on the top of the card holder, and the outer peripheral wall of the limiting pin is engaged inside the U-shaped slot and the size is adapted to it.

[0011] Furthermore, the two limiting plates are respectively located directly above the two card plates, and the card plates are attached to the top of the limiting plates.

[0012] Furthermore, two lifting rings are installed on the outer wall of the lifting device and inside the lifting plate, and the lifting plate is located at the bottom of the lifting device.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This workpiece rotating lifting device uses a limit pin inserted into the lifting shaft to limit its position. The rotating shaft drives the counterweight plate, clamping plate, and clamping seat to rotate and adjust their angles. The counterweight plate makes the weight on the side of the clamping plate closer to the lifting shaft less than the weight on the side farther from the lifting shaft. The clamping plate lifts the clamping seat upward to connect with and fix it to the limit pin, which facilitates the limiting and fixing of the lifting beam, preventing the lifting beam from rotating and improving the overall stability of the rotating lifting device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 The workpiece rotating lifting device in this embodiment includes a lifting device 1, a lifting ring 2 and a lifting plate 3. The bottom of the lifting device 1 is provided with a rotating structure and a positioning structure.

[0023] The rotating structure includes a hanging shaft 4 fixedly installed on the inner wall of the bottom of the hanging plate 3. A first bearing 5 and a second bearing 6 are respectively installed on the outer peripheral wall of the hanging shaft 4. An adjusting sleeve 7 is fixedly installed on the outer peripheral wall of both the first bearing 5 and the second bearing 6. A hanging beam 8 is fixedly installed on the outer peripheral wall of the adjusting sleeve 7. The first bearing 5 includes an inner ring, an outer ring and a first ball. The first ball is located between the inner ring and the outer ring. The inner ring is fixedly installed on the outer peripheral wall of the hanging shaft 4 and the outer ring is fixedly installed on the inner peripheral wall of the adjusting sleeve 7. The second bearing 6 includes an upper ring, a lower ring and a second ball. The second ball is located between the upper ring and the lower ring. The bottom of the lower ring is installed on the outer peripheral wall of the hanging shaft 4 and the upper ring is fixedly installed on the inner peripheral wall of the adjusting sleeve 7.

[0024] The positioning structure includes a limiting pin 9 inserted inside the lifting shaft 4, with a pin 10 inserted inside the limiting pin 9. The lifting shaft 4 has a first insertion hole, into which the limiting pin 9 is inserted in a matching size. The limiting pin 9 also has a second locking hole, into which the pin 10 is inserted in a matching size. A mounting plate 11 is fixedly installed on the bottom outer wall of the lifting beam 8. Four connecting plates 12 are fixedly installed on the bottom outer wall of the mounting plate 11. The internal rotation of two adjacent connecting plates 12 is connected... A rotating shaft 13 is connected, and a counterweight plate 14 is fixedly installed on the outer peripheral wall of the rotating shaft 13. A clamping plate 15 is fixedly installed on the bottom outer wall of the counterweight plate 14. Two limiting plates 16 are fixedly installed on the bottom outer wall of the mounting plate 11. The two limiting plates 16 are located directly above the two clamping plates 15. The clamping plates 15 are attached to the top of the limiting plates 16. A clamping seat 17 is fixedly installed on the top of the clamping plate 15. A U-shaped groove is opened on the top of the clamping seat 17. The outer peripheral wall of the limiting pin 9 is engaged inside the U-shaped groove and the size is compatible.

[0025] In this embodiment, the card plate 15 is affected by the gravity of the counterweight plate 14, which pushes the side of the card plate 15 closest to the hanging shaft 4 upward and rotates it. The limiting plate 16 limits the card plate 15, causing the limiting pin 9 to engage inside the card seat 17.

[0026] The working principle of the above embodiments is as follows:

[0027] When it is necessary to rotate the lifting beam 8, the worker pushes the left side of the clamping plate 15 away from the lifting shaft 4 upwards. At this time, the limiting pin 9 separates from the clamping seat 17. Then, the right side of the clamping plate 15 is pushed so that the clamping seat 17 rotates downwards to adjust the angle. Then, the action of the first bearing 5 and the second bearing 6 drives the lifting beam 8 to rotate 180 degrees. At this time, the left and right clamping seats 17 interchange positions. Then, the clamping plate 15 is released. At this time, the clamping plate 15 is subjected to the gravity of the counterweight plate 14, causing the side of the clamping seat 17 to rotate upwards and lock the limiting pin 9. At this time, the limiting work of the limiting pin 9 is completed.
