[0011] As a further description of the above technical solution:

[0012] The limiting assembly includes a limiting ring disposed on the lower side of the connecting seat. A rotating ring is rotatably connected to the inner wall of the limiting ring.

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a chain-turning machine, comprising a frame 1 for supporting the overall structure. A drive mechanism a3, consisting of a motor, drive shaft, multiple sets of toothed discs, and multiple sets of chains, is located on the outer side of the frame 1. This mechanism drives chain a10 to rotate on the outer side of the toothed discs on the frame 1. A drive shaft mechanism 2, consisting of a drive shaft, multiple sets of toothed discs, and bearing seats, is located on the right side of the frame 1. This mechanism connects chain a10 and chain b11 for synchronous transmission, enabling cargo transport. Chain a10 (model C10B-2-224 sections) is connected to the outer side of the frame 1. A turning mechanism 9, consisting of a guide frame, multiple sets of toothed discs, and a pull rod, is located on the right side of the drive shaft mechanism 2. This mechanism supports chain b11. Chain b11 (model C10B-2-138 sections) is connected to the outer side of the turning mechanism 9. A turning shaft is located on the outer side of the drive shaft mechanism 2. Component 8 consists of a tilting shaft and multiple sets of geared discs. Bearing seats are provided on both sides of the tilting shaft, and a proximity switch assembly 5 is provided on the rear side of the tilting shaft. A drive mechanism b4, consisting of a self-locking geared motor, is provided on the outer side of the tilting shaft assembly 8. The multiple sets of geared discs in the tilting shaft assembly 8 cooperate with the multiple sets of geared discs in the drive shaft mechanism 2, and drive the tilting mechanism 9 to tilt around the drive shaft of the drive shaft mechanism 2. A support frame is provided at the lower part of the drive mechanism b4 to support the drive mechanism b4. A proximity switch assembly 5, consisting of an inductive proximity switch and a lever, is provided on the outer side of the tilting shaft assembly 8 to detect the tilting angle in real time, trigger the motor to start and stop, and ensure accurate tilting position. A guide bar 6 is fixedly connected to the outer side of the frame 1. The tilting shaft assembly 8 and the drive shaft mechanism 2 are connected by chain drive. An adjustment assembly 7 is provided at the lower part of the frame 1, the tilting mechanism 9, and the support frame.

[0033] Reference Figures 1-3The adjustment assembly 7 includes multiple sets of connecting seats 72 fixedly connected to the frame 1, the tilting mechanism 9, and the lower part of the support frame. These seats are in direct contact with the ground and are fixed to the ground using expansion bolts. A movable component 71 is bolted to the outside of each connecting seat 72. The height of the equipment is controlled by adjusting the overlap distance between the movable component 71 and the connecting seat 72. The bolts also assist in locking the movable component 71 to the connecting seat 72, eliminating the need for additional pads or modifications to the AGV, thus reducing production costs and debugging time. An adjusting bolt 75 passes through the inner wall of the connecting seat 72, and an adjusting nut 74 is threaded onto the outside of the adjusting bolt 75. The height of the adjusting nut 74 outside the adjusting bolt 75 is adjusted accordingly. This allows for the adjustment of the height of the connecting seat 72. Through the threaded transmission between the adjusting nut 74 and the adjusting bolt 75, the connecting seat 72 is driven to rise slowly. A limit component 73 is provided on the lower side of the connecting seat 72 to limit the adjusting nut 74, thereby preventing the adjusting nut 74 from loosening due to vibration generated during equipment operation. The adjusting nut 74 is engaged inside the limit component 73. The adjusting component 7 also includes a base 76, which is fixedly connected to the outside of the moving part 71. A regular hexagonal groove is provided in the middle of the base 76, and the adjusting bolt 75 is inserted into the inner wall of the base 76. The base 76 limits the adjusting bolt 75 through the regular hexagonal groove, thereby preventing the adjusting bolt 75 from loosening.

[0034] Reference Figures 2-4 The limiting component 73 includes a limiting ring 731 disposed on the lower side of the connecting seat 72. The limiting ring 731 contacts the lower side of the connecting seat 72 but is not connected to the connecting seat 72, allowing the limiting ring 731 to rotate. A rotating ring 732 is rotatably connected to the inner wall of the limiting ring 731. By rotating, the guide groove 733 drives the limiting member 734 to extend to the outside of the limiting ring 731. The inner wall of the rotating ring 732 is hollow and can accommodate the limiting member 734. A guide is provided through the outer side of the rotating ring 732. The guide groove 733 is arc-shaped. When the rotating ring 732 rotates, the guide groove 733 can guide the movement of the limiting member 734. The rotating ring 732 is slidably connected to the inner wall of the guide groove 733, and there are six sets of limiting members 734. They can abut against the six planes on the outside of the adjusting nut 74 to limit the adjusting nut 74 and prevent it from loosening. The limiting member 734 is slidably connected to the inner wall of the limiting ring 731 and contacts the plane on the outside of the adjusting nut 74.

[0035] Reference Figures 2-4The limiting component 73 also includes a connecting plate a735 fixedly connected to the outside of the rotating ring 732. The connecting plate a735 passes through the limiting ring 731. A connecting plate b736 is fixedly connected to the outside of the limiting ring 731. The connecting plate a735 and the connecting plate b736 are fixedly installed by bolts a737 and damping nuts 738. The bolts a737 are threaded into the inner wall of the damping nuts 738. By the connecting plate a735 approaching the connecting plate b736, the rotating ring 732 is driven to rotate. The connecting plate a735 and the connecting plate b736 are then locked by the bolts a737 and the damping nuts 738. The damping nuts 738 can increase the friction between the bolts a737 and the bolts a737, thereby improving the stability between the bolts a737 and the damping nuts 738. A through groove is opened through the outside of the connecting plate a735. Since the running trajectory of the connecting plate a735 is arc-shaped, the bolts a737 can slide on the inner wall of the through groove by opening the through groove, reducing motion interference.

[0036] Reference Figure 3 and Figure 4 A limiting frame 12 is fixedly connected to the outer side of the limiting ring 731 to limit the connecting block 13, thereby controlling the rotation angle of the limiting assembly 73. This ensures that the multiple limiting parts 734 in the limiting assembly 73 are always aligned with the six planes on the outer side of the adjusting nut 74. A connecting block 13 is fixedly connected to the lower part of the connecting seat 72 near the outer surface of the limiting ring 731. The limiting frame 12 is slidably connected to the inner wall of the connecting block 13. The limiting frame 12 and the connecting block 13 cooperate to control the position of the limiting assembly 73, allowing the limiting assembly 73 to rotate at a certain angle. A scale line 711 is provided on the front side of the moving part 71, and an indicator 712 is provided on the front side of the connecting seat 72. By cooperating with the scale line 711 on the front side of the moving part 71 and the indicator 712 on the front side of the connecting seat 72, the adjustment amount can be accurately displayed, allowing the operator to intuitively understand the degree of height adjustment and achieve precise adjustment.

[0037] Working principle: When the height of the device needs to be adjusted, the adjusting bolt 75 is rotated, and the threaded engagement of the adjusting nut 74 drives the moving part 71 to slide up and down along the connecting seat 72, thereby adjusting the height of the frame 1, the flipping mechanism 9 and the support frame to adapt to AGV equipment of different heights. No additional pads or modifications to the AGV are required, reducing production costs and debugging time. The scale line 711 on the front of the moving part 71 cooperates with the indicator 712 on the front of the connecting seat 72 to intuitively display the adjustment amount and achieve precise control (e.g., 1mm per division). The regular hexagonal groove in the middle of the base 76 is inserted into the adjusting bolt 75 to restrict the circumferential rotation of the adjusting bolt 75, prevent the bolt from shifting during the adjustment process and ensure the stability of the height adjustment.

[0038] When the limiting component 734 needs to lock the adjusting nut 74, the bolt a737 is rotated. Through the threaded connection between the bolt a737 and the damping nut 738, the connecting plate a735 is driven to move closer to the connecting plate b736. At the same time, the rotating ring 732 is driven to rotate. The multiple sets of arc-shaped guide grooves 733 on the rotating ring 732 drive the six sets of limiting components 734 to slide along the arc-shaped trajectory. The limiting components 734 press against the outer plane of the adjusting nut 74. Through multi-point contact, the rotation of the nut is restricted, preventing the nut from loosening due to equipment vibration. At the same time, the damping nut 738 can increase the friction and lock the position of the rotating ring 732, ensuring that the limiting component 734 continuously presses the nut.

[0039] The limiting frame 12 on the outer side of the limiting ring 731 is slidably connected to the inner wall of the connecting block 13 at the lower part of the connecting seat 72, limiting the maximum rotation angle of the rotating ring 732. When aligned with the plane of the adjusting nut 74, the limiting ring 731 can be rotated for adjustment, avoiding contact with the edges of the adjusting nut 74, which would cause the limiting to fail. At the same time, the limiting ring 731 is only located in the upper half of the adjusting nut 74 and does not affect the operator's use of the adjusting nut 74.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
