DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] like Figure 1-4 As shown, the hook-type traction AGV of this embodiment includes a vehicle body 10, which includes a chassis 11. A hook assembly 20 is provided at the rear end of the chassis 11. The hook assembly 20 of this embodiment includes a base plate 21, which is fixedly connected to the chassis 11. A circular arc-shaped guide rail 22 is provided on the base plate 21, which is slidably engaged with a slide 23. A hook mechanism is mounted on the slide 23. The hook mechanism of this embodiment includes a hook 24 and a lift drive mechanism for driving the hook up and down.

[0028] In a preferred embodiment of this embodiment, the slide 23 is provided with roller assemblies located on either side of the arc-shaped guide rail 22. Furthermore, the roller assemblies include at least two rollers 25. In this embodiment, each roller assembly includes three rollers. The roller assemblies provided on the slide 23 and the rolling engagement between the rollers 25 and the arc-shaped guide rail 22 can reduce resistance to movement of the slide 23 along the arc-shaped guide rail 22.

[0029] In the preferred embodiment of this embodiment, first spring tabs 26 are mounted on the base plate 21, one at each end of the arc-shaped guide rail 22. Second spring tabs 27 are also mounted on either side of the slide plate 23, corresponding to the first spring tabs 26. The limited cooperation between the first and second spring tabs 26, 27, restricts the sliding range of the slide plate 23, preventing it from moving out of the arc-shaped guide rail 22.

[0030] like Figure 2-3As shown, the hook mechanism of this embodiment includes a hook bracket 28 fixedly connected to the slide 23, with a vertical guide rod 29 disposed therein. Specifically, the hook 24 of this embodiment includes a hook portion 241 and a connecting portion 242. The connecting portion 242 is sleeved onto the vertical guide rod 29, and a lifting drive mechanism is used to drive the connecting portion 242 to move up and down along the vertical guide rod 29. Specifically, the connecting portion 242 of this embodiment is a connecting plate, on which a linear bearing 30 is mounted that slides with the vertical guide rod 29. In this embodiment, the lifting drive mechanism is fixedly mounted on a motor 31 on the hook bracket 28 and a turntable 32 that is transmission-connected to the output shaft of the motor 31. The axis of the turntable 32 is horizontal. In this embodiment, the turntable 32 is mounted on the output shaft of the motor 31. The turntable 32 is provided with a limit shaft 33 that is eccentrically positioned relative to its rotational axis. The limit shaft 33 is engaged with the connecting plate and is always located below the connecting plate. In this manner, the motor 31 drives the turntable 32 to rotate. When the limiting shaft 33 rotates upward about the axis of the turntable 32, the limiting relationship between the limiting shaft 33 and the connecting plate drives the connecting plate to move upward along the vertical guide rod 29. Simultaneously, when the limiting shaft 33 rotates downward about the axis of the turntable 32, the weight of the hook 24 causes the hook to move downward along the vertical guide rod 29. In this embodiment, the hook bracket 28 includes an outer cover that covers the vertical guide rod 29. In this embodiment, the hook bracket 28 includes a connecting seat 35, which is fixedly connected to the slide plate 23.

[0031] In a preferred implementation manner of this embodiment, a roller 34 is installed on the limiting shaft 33, and the roller 34 and the connecting plate are in rolling cooperation, so that the friction between the limiting shaft 33 and the connecting plate can be reduced.

[0032] The above-described embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. The scope of protection of the present invention shall be subject to the claims.
