[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This utility model provides a protective structure for the fork arm guide rail of an AGV trolley, such as... Figure 1 As shown, it includes: a limiting component disposed on the fork arm of the AGV trolley and a guide rail assembly slidably disposed on the AGV trolley for cooperating with the limiting component to limit and protect the fork arm of the AGV trolley; the limiting component and the guide rail assembly are slidably connected.

[0023] In practice, an encoder is installed on the AGV to monitor the extension distance of the fork arm. A cable chain is also installed to power the fork arm and provide signal recognition from the AGV body. Both the encoder and the cable chain are wired. Limiting components and sliding rail components are installed on the AGV fork arm. The extension distance of the AGV fork arm is further limited by the cooperation of the limiting components and the sliding rail components to prevent damage caused by exceeding the maximum extension distance. During the extension of the AGV fork arm, the fork arm drives the limiting components and the sliding rail components to move synchronously. When it reaches the maximum distance of the sliding rail components, the sliding rail components stop moving, and the fork arm continues to drive the limiting components to move. The limiting components and the sliding rail components slide apart. The limiting components can only move to the maximum distance of the sliding rail components to protect the AGV and prevent the encoder rope and cable chain from breaking.

[0024] Furthermore, the guide rail assembly includes a first sliding seat, a second sliding seat, a mounting seat, and a fork arm retraction limiting block for buffering the impact of the AGV trolley's fork arm; the first sliding seat and the second sliding seat are respectively fixedly connected to both ends of the mounting seat; the first sliding seat, the second sliding seat, and the mounting seat cooperate to form an active area for the AGV trolley's fork arm to extend and retract; the limiting component is slidably connected to the first sliding seat and the second sliding seat, and is located within the active area.

[0025] In Embodiment 1, the first sliding seat and the second sliding seat are slidably connected to the AGV trolley to ensure the overall tightness of the AGV trolley. Before the fork arm assembly moves to the maximum moving distance of the slide rail assembly within the AGV trolley, the fork arm is always housed within the active area. When the fork arm travels to the maximum moving distance of the slide rail assembly within the AGV trolley, the limiting component slides relative to the first sliding seat and the second sliding seat. When the fork arm moves within the active area, the directional distance of the fork arm extension and retraction of the AGV trolley is guided and limited by the limiting component and the first and second sliding seats.

[0026] Furthermore, the limiting component includes: a first slide rail and a second slide rail; the first slide rail and the second slide rail are respectively disposed on both sides of the AGV trolley fork arm; the first slide rail is slidably connected to the first sliding seat; and the second slide rail is slidably connected to the second sliding seat.

[0027] In Embodiment 2, the first slide rail and the second slide rail are respectively set on both sides of the AGV trolley fork arm. The fork arm structure is made of wear-resistant material to ensure that it remains smooth even after long-term operation, so as to ensure that the AGV trolley fork arm remains stable when it moves in and out of the activity area.

[0028] Furthermore, it also includes: a fork extension limit block disposed on the AGV trolley and a limit stop plate disposed on the slide rail assembly for cooperating with the fork extension limit block to limit the maximum travel distance of the slide rail assembly; the limit stop plate is detachably connected to the slide rail assembly; the limit stop plate can abut against the fork extension limit block.

[0029] In other embodiments, as shown in the appendix Figure 2-3 As shown, to prevent the slide rail assembly from moving beyond its maximum stroke during the movement of the AGV's fork arm, a limit stop is provided on the slide rail assembly, and a fork arm extension limit block is provided on the AGV. The fork arm extension limit block is located at the maximum movement distance of the slide rail assembly. When the slide rail assembly moves to the maximum distance, the fork arm extension limit block on the AGV will abut against the limit stop on the slide rail assembly, thereby limiting the slide rail assembly and preventing it from moving beyond its maximum stroke.

[0030] Furthermore, it also includes: a slide rail guide block disposed on the AGV trolley for limiting and guiding the movement direction of the slide rail assembly; the slide rail guide block can abut against the slide rail assembly.

[0031] In other embodiments, a slide rail guide block is disposed on the AGV trolley, and a guide groove is provided on the slide rail guide block to guide the movement direction of the slide rail assembly and limit the irregular movement of the AGV trolley's fork arm.

[0032] Optionally, the slide rail guide block is also provided with shims for adjusting the spacing on the slide rail guide block.

[0033] In other embodiments, the model and size of the fork arm mounted on the AGV may vary. To achieve a better guiding effect for the slide rail guide block, the guide groove of the slide rail guide block can be filled to make the contact between the guide groove of the slide rail guide block and the slide rail tighter, thus improving the guiding function of the slide rail guide block.

[0034] Optionally, it also includes: a guide installed on the AGV trolley for guiding the retraction of the AGV trolley's fork arm.

[0035] In other embodiments, the guides on the AGV trolley provide a certain guiding effect when the AGV trolley fork arms retract, so that they return to the original position of the AGV trolley, thus reducing the retraction error.

[0036] This utility model discloses a fork arm guide rail protection structure for an AGV trolley. Through the coordinated work of the limiting component and the guide rail component, it effectively limits the movement range of the fork arm, reducing equipment damage and safety hazards caused by excessive extension and retraction. It adopts a special limiting baffle and guide block to avoid potential accidents caused by fork arm deviation or collision during operation, thereby improving the overall movement safety of the fork arm.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
