[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] Please see Figures 1-3 The first aspect of this utility model provides a roller ring gripping device, including: a lifting mechanism 1, and a gripping mechanism 2 connected to the lifting mechanism 1.

[0026] In some embodiments, the lifting mechanism 1 is a component in the roller ring conveying device that carries and transfers heavy objects during the conveying operation, and includes: a first telescopic cylinder 11, a first telescopic arm 12 slidably connected to the first telescopic cylinder 11, and a first hydraulic cylinder 13 connected to the first telescopic cylinder 11 and the first telescopic arm 12.

[0027] In some embodiments, the first telescopic arm 12 is adapted to the first telescopic cylinder 11. Specifically, the first telescopic arm 12 is disposed in the first telescopic cylinder 11 and slidably connected. The output end of the first hydraulic cylinder 13 is connected to the first telescopic arm 12. Under the output action of the first hydraulic cylinder 13, the first telescopic arm 12 can be displaced along the setting direction of the first telescopic cylinder 11, thereby driving the gripping mechanism 2 to be displaced along the setting direction of the first telescopic cylinder 11.

[0028] Furthermore, the lifting mechanism 1 also includes a second telescopic arm 14 connected to the first telescopic arm 12, and a second hydraulic cylinder 15 connected to both the first telescopic arm 12 and the second telescopic arm 14. The end of the second telescopic arm 14 furthest from the first telescopic arm 12 is also connected to the gripping mechanism 2. In some embodiments, one end of the first telescopic arm 12 is hinged to one end of the second telescopic arm 14, and the output end of the second hydraulic cylinder 15 is connected to the second telescopic arm 14. Under the output action of the second hydraulic cylinder 15, the second telescopic arm 14 can rotate about the connection point with the first telescopic arm 12 as an axis, thereby adjusting the angle of the gripping mechanism 2 so that the gripping mechanism 2 can better fit the roller ring to grip it.

[0029] In some embodiments, the gripping mechanism 2 is the part of the roller ring gripping device used for gripping the roller ring. Further, the gripping mechanism 2 includes a gripping block 21, a threaded rod 22 connected to the gripping block 21, a threaded block 23 threadedly connected to the threaded rod 22, and a gripping claw 24 connected to the threaded block 23. The gripping block 21 is a regular polygonal structure. By designing the gripping block 21 as a regular polygon, the operator can arrange a set of threaded rods 22, threaded blocks 23 and gripping claws 24 on the edges of each gripping block 21, thereby using the gripping claws 24 to move closer to each other to achieve the effect of gripping the roller ring.

[0030] Furthermore, the gripping mechanism 2 also includes a motor 25, wherein one end of the threaded rod 22 is rotatably connected to the gripping block 21, and the other end is connected to the motor 25. Under the transmission action of the motor 25, the threaded rod 22 can rotate, thereby driving the threaded block 23 threadedly connected to the threaded rod 22 to move along the direction set by the threaded rod 22, thereby driving multiple sets of gripping claws 24 to move closer to each other.

[0031] In some more preferred embodiments, the gripping mechanism 2 further includes a guide plate 26, one end of which is connected to the gripping block 21 and the other end of which is connected to the motor 25 to fix the motor 25. The guide plate 26 is provided with a guide groove 261, and the threaded block 23 is provided with a guide key that matches the guide groove 261. The guide key is slidably connected to the guide groove 261 and slides in the guide groove 261 through the guide key, thereby enhancing the smoothness of the threaded block 23 when it moves along the direction set by the threaded rod 22.

[0032] In some embodiments, the gripping claw 24 has an arc-shaped structure, with its top connected to the threaded block 23. The multiple sets of gripping claws 24 approach each other and abut against the roller ring to grip the roller ring. In some more preferred embodiments, the bottom of the gripping claw 24 is provided with an inwardly curved protrusion 241. When the gripping claw 24 grips the roller ring, the protrusion 241 at the bottom of the gripping claw 24 abuts against the groove in the middle of the roller ring, thereby realizing the safe gripping process of the roller ring.

[0033] The second aspect of this utility model provides a roller ring transfer vehicle, including the roller ring gripping device described in Embodiment 1.

[0034] Finally, it should be noted that the embodiments disclosed in this utility model are merely preferred embodiments of this utility model and are only used to illustrate the technical solutions of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
