Description

A high-stability forklift AGV Technical Field

[0001] This utility model relates to the field of AGV technology, specifically to a highly stable forklift-type AGV. Background Technology

[0002] Forklift AGVs are intelligent material handling equipment widely used in warehousing, logistics, and manufacturing. With the continuous maturation of artificial intelligence technology, forklift AGVs have also experienced rapid development.

[0003] Forklift-type AGVs are typically equipped with a telescopic drive mechanism to extend and retract the forks, allowing them to adapt to different picking depths. Existing telescopic drive mechanisms are usually mounted on the mast's lifting frame. When the telescopic drive mechanism extends the forks to pick up goods, the increased distance between the forks and goods and the mast, along with the increased distance between the goods' center of gravity and the mast, leads to greater torque and stress on the mast, telescopic drive mechanism, and lifting frame. This not only causes instability during picking but also poses a safety risk of forward tilting. Furthermore, it accelerates metal fatigue, affecting service life. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a highly stable forklift-type AGV, which improves the stability and safety of picking up goods and extends the service life of masts, etc.

[0005] To achieve the above objectives, this utility model provides a high-stability forklift-type AGV, comprising a vehicle body; a mast movably mounted on the vehicle body; a scissor-type telescopic mechanism mounted on the vehicle body, the scissor-type telescopic mechanism being used to drive the mast to move; a lifting frame movably mounted on the mast; two fork arms movably mounted on the lifting frame; and an adjustment mechanism for adjusting the distance between the two fork arms.

[0006] Preferably, the vehicle body is provided with a movable base, the door is mounted on the base, and the scissor-type telescopic mechanism is used to drive the base to move.

[0007] Preferably, casters are provided on both sides of the base, and two wheel grooves are provided on the vehicle body to cooperate with the casters.

[0008] Preferably, the vehicle body has a notch, the base is disposed in the notch, and the two wheel grooves are respectively disposed on the two opposite side walls of the notch.

[0009] Preferably, the scissor-type telescopic mechanism includes a first connecting frame, a second connecting frame, a scissor arm assembly, and a first driving member; the first connecting frame is mounted on the vehicle body, the second connecting frame is mounted on the base, the scissor arm assembly is connected to the first connecting frame and the second connecting frame respectively, and the first driving member is mounted on the first connecting frame and connected to the scissor arm assembly.

[0010] Preferably, the adjustment mechanism includes two second drive members, which are mounted on the lifting frame, and each second drive member is connected to one of the fork arms.

[0011] Preferably, the lifting frame is provided with two guide rails, which are arranged in an upper and lower structure; the adjustment mechanism also includes two hanging pulley assemblies, each of which is provided on a corresponding fork arm, and the hanging pulley assembly is slidably engaged on the two guide rails.

[0012] The beneficial effects of this utility model are:

[0013] This utility model discloses a high-stability forklift-type AGV, which uses a scissor-type telescopic mechanism to drive the mast and fork arms to move synchronously. This eliminates the conventional forklift-type AGV design that uses a telescopic mechanism on the mast to drive the fork extension and retraction. The fork arms do not extend or retract relative to the mast. In this way, after picking up goods, the torque and stress on the mast, lifting frame, etc., can be reduced, reducing the risk of forward tilting. This improves the stability and safety of picking up goods, and also reduces the mechanical wear of the scissor-type telescopic mechanism, lifting mechanism, mast, etc., extending their service life.

[0014] Meanwhile, a scissor-type telescopic mechanism is used to drive the mast movement. This mechanism is simple in structure, has a strong load-bearing capacity, enhances the lifting capacity of the two fork arms, and is easy to maintain. Furthermore, by designing an adjustment mechanism to adjust the distance between the two fork arms, it is possible for the two fork arms to lift goods of different sizes, thereby expanding the applicability of this forklift-type AGV.

[0029] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0032] As shown in Figures 1-8, in one embodiment of this utility model, a high-stability forklift-type AGV is provided, including a vehicle body 10, a mast 20, a scissor-lift telescopic mechanism 30, a lifting frame 40, two fork arms 50, and an adjustment mechanism 60. The mast 20 is movably mounted on the vehicle body 10, and the scissor-lift telescopic mechanism 30 is mounted on the vehicle body 10, used to drive the mast 20 to move. The lifting frame 40 is vertically mounted on the mast 20, and the lifting direction of the lifting frame 40 on the mast 20 is spatially perpendicular to the moving direction of the mast 20 on the vehicle body 10. Of course, a lifting mechanism (not shown in the figures) is also installed on the mast 20 to drive the lifting frame 40 to drive the two fork arms 50 to perform lifting actions on the mast 20. The lifting mechanism is prior art and will not be described in detail in this embodiment.

[0033] Two fork arms 50 are movably mounted on the lifting frame 40. The direction of movement of the fork arms 50 on the lifting frame 40 is spatially perpendicular to the lifting direction of the lifting frame 40 on the mast 20 and the direction of movement of the mast 20 on the vehicle body 10, respectively. An adjustment mechanism 60 is mounted on the lifting frame 40 and is used to adjust the distance between the two fork arms 50.

[0034] This embodiment discloses a high-stability forklift AGV that uses a scissor-lift telescopic mechanism 30 to drive the mast 20 and fork arms 50 to move synchronously. This eliminates the conventional forklift AGV design that uses a telescopic mechanism on the mast 20 to drive the fork extension and retraction. The fork arms 50 do not extend or retract relative to the mast 20. This reduces the torque and stress on the mast 20, lifting frame 40, etc., after picking up goods, reducing the risk of forward tilting and thus improving the stability and safety of picking up goods. It also reduces mechanical wear on the scissor-lift telescopic mechanism 30, lifting mechanism, mast 20, etc., extending their service life.

[0035] Meanwhile, a scissor-type telescopic mechanism 30 is used to drive the mast 20 to move. This mechanism has a simple structure, strong load capacity, and can improve the lifting capacity of the two fork arms 50, while also being easy to maintain. Furthermore, by designing an adjustment mechanism 60 to adjust the distance between the two fork arms 50, the two fork arms 50 can lift goods of different sizes, thereby expanding the applicability of this forklift-type AGV.

[0036] In one embodiment, the vehicle body 10 is provided with a movable base 70, the mast 20 is fixedly mounted on the base 70, and the scissor telescopic mechanism 30 is used to drive the base 70 to move. By mounting the mast 20 on the base 70, the process of the scissor telescopic mechanism 30 driving the mast 20 to move is made smoother, thus improving the stability of picking up goods.

[0037] In one embodiment, casters 71 are provided on both sides of the base 70, and two wheel grooves 11 are provided on the vehicle body 10 to mate with the casters 71. A notch 12 is provided on the vehicle body 10, and the base 70 is located within the notch 12. The two wheel grooves 11 are respectively located on two opposite side walls of the notch 12. When the scissor-type telescopic mechanism 30 drives the gantry 20 to move within the notch 12, the casters 71 on both sides of the base 70 can only roll within their corresponding wheel grooves 11. The casters 71 will not contact the ground, avoiding interference from debris on the ground, thereby improving the smoothness of the extension and retraction process of the base 70.

[0038] In one embodiment, the scissor-type telescopic mechanism 30 includes a first connecting frame 31, a second connecting frame 32, a scissor arm assembly 33, and a first driving member 34. The first connecting frame 31 is fixedly mounted on the vehicle body 10, the second connecting frame 32 is fixedly mounted on the base 70, the scissor arm assembly 33 is connected to the first connecting frame 31 and the second connecting frame 32 respectively, and the first driving member 34 is hinged to the first connecting frame 31 and connected to the scissor arm assembly 33.

[0039] Both the first connecting frame 31 and the second connecting frame 32 are rectangular frame structures, which increases the robustness of the connection between the first connecting frame 31 and the base 70, and between the second connecting frame 32 and the vehicle body 10. The first driving member 34 is an electric cylinder. By extending its push rod, the first driving member 34 can drive the scissor arm assembly 33 to deform, thereby driving the base 70 and the mast 20 to move outward.

[0040] In one embodiment, the adjusting mechanism 60 includes two second drive members 61, which are fixedly mounted on the lifting frame 40. Each second drive member 61 is connected to a fork arm 50. The second drive members 61 are also electric cylinders. The extension and retraction direction of the push rod of the second drive member 61 is parallel to the movement direction of the fork arm 50. The two second drive members 61 are arranged in an upper and lower configuration, and the extension and retraction directions of the push rods of the two second drive members 61 are opposite. The push rod of the second drive member 61 is connected to the fork arm 50 through a connecting block 62. By extending or retracting its push rod, the second drive member 61 can move the fork arm 50 connected to it, thus achieving the adjustment of the distance between the two fork arms 50. Of course, the two second drive members 61 can be configured to operate synchronously or independently.

[0041] In one embodiment, the lifting frame 40 is provided with two guide rails 41, arranged in an upper and lower configuration. The adjusting mechanism 60 also includes two hanger-type pulley assemblies 63, each hanger-type pulley assembly 63 being mounted on a corresponding fork arm 50, and the hanger-type pulley assembly 63 slidingly engaging with the two guide rails 41. This structural design not only allows the fork arms 50 to move smoothly on the lifting frame 40, but also ensures the stability of the connection between the fork arms 50 and the lifting frame 40.

In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the 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 or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
