[0002] The slewing bearing is a large bearing that can withstand comprehensive loads and can withstand large axial, radial loads and overturning moments at the same time.

[0003] During the production and processing of the slewing bearing, a flipping device is used to flip it. At present, the flipping device clamps the slewing bearing by moving the limit plates towards each other. The slewing bearing has different specifications due to different application occasions, and the current limit plates are mostly fixedly installed on the flipping device. This results in the limit plates on the flipping device being able to clamp only one specification of the slewing bearing, and the flipping device cannot clamp and limit slewing bearings of different specifications, causing the slewing bearing to shake or fall off after clamping, which not only affects the adaptability of the flipping device, but also makes it impossible to ensure the stability of the slewing bearing when limiting.

A guide cylinder 18 corresponding to the guide rod 17 is provided on the placing table 3, and a spring 19 corresponding to the guide rod 17 is welded between the guide cylinder 18 and the base 1. The output end of the first hydraulic cylinder 2 can drive the placing table 3 to lift, and when the placing table 3 lifts, the mutual cooperation between the guide cylinder 18 and the guide rod 17 can ensure the smooth movement of the placing table 3;

[0022] The placing table 3 is horizontally arranged above the base 1. The guide rod 17 is vertically arranged, the spring 19 is vertically welded, the bracket 5 is vertically arranged on both sides of the base 1, and the guide cylinder 18 is a ring structure with an open bottom. A second hydraulic cylinder 6 is fixedly installed on the bracket 5. A slider 7 connected to the output end of the second hydraulic cylinder 6 is slidably sleeved in the bracket 5, and a telescopic rod 8 is fixedly installed on the slider 7. The output end of the second hydraulic cylinder 6 can drive the slider 7 to lift, so that the slider 7 can drive the limiting plate 4 to approach or move away from the placing table 3. The movement of the output end of the telescopic rod 8 can drive the two limiting plates 4 to limit the slewing bearing from both sides;

[0023] The output end of the telescopic rod 8 is fixedly connected to a connecting plate, and a motor 9 is fixedly installed on the connecting plate. The output end of the motor 9 is fixedly connected to a rotating shaft 10, and a sleeve 11 is fixedly installed on the rotating shaft 10. A connecting rod 12 is slidably sleeved in the sleeve 11, and the limiting plate 4 is arranged on the connecting rod 12. The rotating shaft 10 is horizontally arranged on both sides of the placing table 3, and the limiting plate 4 and the connecting rod 12 extend to one side outside the sleeve 11. The output end of the motor 9 can drive the rotating shaft 10 to rotate, and the rotating shaft 10 drives the sleeve 11 and the limiting plate 4 to be able to flip, so that the slewing bearing can be flipped;

[0024] A fixing component for fixing the connecting rod 12 is installed in the sleeve 11;

[0025] The fixing component includes a pressing plate 13 placed on the sleeve 11, and a positioning rod 14 fixedly installed on the pressing plate 13 and extending into the connecting rod 12. A resisting rod 15 is placed in the sleeve 11, and a clamping plate 16 corresponding to the connecting rod 12 is provided on the resisting rod 15. The connecting rod 12 equipped with the limiting plate 4 is extended into the sleeve 11, and then the resisting rod 15 equipped with the clamping plate 16 is extended into the sleeve 11. A locking bolt is used to connect the pressing plate 13 and the sleeve 11, and a fixing bolt is used to connect the sleeve 11 and the resisting rod 15, making the installation of the limiting plate 4 more convenient;

[0026] A locking bolt that is detachably connected to the sleeve 11 is threadedly connected to the pressing plate 13, and a positioning hole corresponding to the positioning rod 14 is provided on the connecting rod 12. The clamping plate 16 and the resisting rod 15 extend to one side outside the sleeve 11. The clamping plate 16 is of a U-shaped structure, and a fixing bolt that is detachably connected to the resisting rod 15 is threadedly connected to the sleeve 11;

[0027] It is further explained that before limiting the slewing bearing, first select the limiting plate 4 according to the specifications of the slewing bearing, so that the specifications of the limiting plate 4 can limit different specifications of slewing bearings. At the same time, the selected limiting plate 4 can fit with the slewing bearing, which not only improves the adaptability of the flipping equipment, but also ensures the stability of the slewing bearing during flipping;

[0028] It should be noted that the specific model specifications of the hydraulic cylinder 1-2, the hydraulic cylinder 2-6, the telescopic rod 8, and the motor 9 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated.

[0029] The functional principle of the present utility model can be described through the following operation method:

[0030] When the slewing bearing needs to be flipped;

[0031] The operator selects the limiting plate 4 that meets the specifications according to the specifications of the slewing bearing;

[0032] The connecting rod 12 equipped with the limiting plate 4 is extended into the sleeve 11, and the pressing plate 13 is placed on the sleeve 11, so that the positioning rod 14 on the pressing plate 13 can extend into the positioning hole in the connecting rod 12, and a locking bolt is used to connect the pressing plate 13 and the sleeve 11;

[0033] The resisting rod 15 is extended into the sleeve 11, so that the resisting rod 15 drives the clamping plate 16 to clamp the connecting rod 12, and a fixing bolt is used to connect the sleeve 11 and the resisting rod 15, thereby realizing the installation of the limiting plate 4;

[0034] The output end of the second hydraulic cylinder 6 drives the slider 7 to slide within the bracket 5, causing the slider 7 to drive the telescopic rod 8, the motor 9, the sleeve 11, and the limit plate 4 to move to the positions on both sides of the slewing bearing;

[0035] The output ends of the two telescopic rods 8 drive the two limit plates 4 to move towards each other, enabling the limit plates 4 to clamp the slewing bearing from both sides;

[0036] The output end of the second hydraulic cylinder 6 drives the slider 7 to move upward, causing the limit plate 4 to drive the slewing bearing to disconnect from the placement table 3. At the same time, the output end of the first hydraulic cylinder 2 drives the placement table 3 to move downward. When the placement table 3 moves downward, it drives the guide cylinder 18 to slide on the guide rod 17, and the spring 19 is stressed;

[0037] The output end of the motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the sleeve 11 to rotate. When the sleeve 11 rotates, it drives the connecting rod 12 and the limit plate 4 to flip the slewing bearing;

[0038] When the slewing bearing is placed, the output end of the first hydraulic cylinder 2 drives the placement table 3 back to the initial position. The output end of the second hydraulic cylinder 6 drives the limit plate 4 and the slewing bearing to move downward, enabling the slewing bearing to fall onto the placement table 3. The output end of the telescopic rod 8 drives the limit plate 4 back to the initial position to facilitate subsequent processing of the slewing bearing.

[0039] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
