Description

Technical Field

[0001] This application relates to the field of transportation equipment technology, and in particular to a C-type AGV for rapid pallet transport. Background Technology

[0002] In warehousing and logistics automation systems, Automated Guided Vehicles (AGVs) are widely used for the automated handling of various materials. Among them, forklift-type AGVs are one of the mainstream devices for achieving efficient handling of palletized goods because they can directly pick up, lift, and transfer standardized palletized goods.

[0003] Currently, most common forklift AGVs consist of two relatively independent parts. One part is the power drive unit that provides walking, positioning, and navigation capabilities, such as the autonomous mobile AGV chassis or forklift body; the other part is the fork arm assembly that performs cargo loading and lifting. During the handling process, the power drive unit first travels to the fork arm assembly placement location, completes the mechanical docking and locking connection between the two, then the power unit controls the fork arm assembly to extend into the bottom of the pallet and lift the cargo off the ground, and finally the power unit moves the fork arm assembly and cargo together to complete the transportation.

[0004] However, coordination is required before transportation, and the coordination process is quite complicated, which leads to a longer operation cycle and affects the overall transportation efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a C-type AGV for rapid pallet transport, which can improve transportation efficiency.

[0006] The technical solution provided in this application is described below:

[0007] This application provides a C-type AGV for rapid pallet transport, comprising: Chassis body, outriggers, drive components, and fork arms; The outriggers are respectively fixed to the same side at both ends of the chassis body. Each outrigger has a receiving space inside, and the drive assembly is disposed in the receiving space and fixedly connected to the outrigger. The fork arm is disposed on the inner side of the support leg and is connected to the drive assembly, which is used to drive the fork arm to move up and down in the vertical direction.

[0008] Optionally, a guide assembly is provided on the support leg, the guide assembly is vertically fixed on the support leg, and the fork arm is connected to the guide assembly.

[0009] Optionally, the guide assembly includes a guide rail and a slider. The guide rail is vertically fixed to the support leg, one side of the slider is slidably connected to the guide rail, and the other side of the slider is fixedly connected to the fork arm.

[0010] Optionally, the support leg is provided with two guide components, which are located on both sides of the drive component.

[0011] Optionally, the fork arm includes a vertical plate and a horizontal plate, the vertical plate being connected to the drive assembly, and the horizontal plate being horizontally disposed at the lower end of the vertical plate.

[0012] Optionally, the fork arm and the drive assembly are connected by one of the following methods: welding, bolting, or hinge.

[0013] Optionally, a first drive wheel is provided at the bottom of the chassis body, and a second drive wheel is provided at the bottom of the outriggers. The first drive wheel is a swivel wheel.

[0014] Optionally, the drive assembly is connected to the fork arm via a connector.

[0015] Optionally, the inner side of the support leg is provided with a perforation, which communicates with the receiving space; One end of the connector is connected to the drive assembly, and the other end passes through the perforation and is connected to the fork arm.

[0016] Optionally, the drive assembly is one of a hydraulic rod, an electric push rod, or a lead screw.

[0017] As can be seen from the above technical solutions, this application has the following beneficial effects: This application fixes outriggers on the same side at both ends of the chassis body and integrates the drive assembly within the outrigger's receiving space. The fork arms are directly mounted inside the outriggers and connected to the drive assembly. The fork arms are used to lift the pallet, and the drive assembly drives the fork arms to rise and fall vertically. Thus, the fork arms, as a fixed integrated part of the AGV body, do not require separate travel to the fork arm assembly placement location for mechanical docking and locking before handling operations. This eliminates the intermediate step of separating and docking the power drive unit from the fork arm assembly in traditional solutions, thereby simplifying the operation process and improving overall transportation efficiency.

[0023] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Traditional forklift AGVs consist of two parts, requiring cumbersome docking during transport, which negatively impacts overall efficiency. This application proposes a C-type AGV for rapid pallet transport to improve efficiency. The specific implementation structure of this application is described below: See Figures 1 to 6 This application provides an embodiment of a C-type AGV for rapid pallet transport, the embodiment comprising: The chassis body 01, outriggers 02, drive assembly 03, and fork arm 04 are included. The outriggers 02 are fixed to the same side at both ends of the chassis body 01. The outriggers 02 have a receiving space inside. The drive assembly 03 is located in the receiving space and is fixedly connected to the outriggers 02. The fork arm 04 is located inside the outriggers 02 and is connected to the drive assembly 03. The drive assembly 03 is used to drive the fork arm 04 to rise and fall in the vertical direction.

[0025] The chassis body 01 is used to support devices such as batteries, control units, and navigation sensors. At both ends of the chassis body 01, on the same side, a support leg 02 is fixedly connected. Thus, in a top-view view, the chassis body 01 and the two support legs 02 together form a "C"-shaped structure, allowing for forklift access from one side of the pallet 05 for handling operations. The fixed connection between the chassis body 01 and the support legs 02 can be achieved by bolting, welding, or integral molding.

[0026] The two sets of outriggers 02 are parallel to each other and are located on the left front end and left rear end of the chassis body 01, respectively. The inner sidewalls of the outriggers 02, that is, the opposite sides of the two outriggers 02, serve as the mounting reference and lateral limit reference surface for the lifting movement of the fork arm 04.

[0027] Each outrigger 02 has a hollow accommodating space inside. The drive assembly 03 is accommodated and fixed inside the accommodating space of the outrigger 02. The drive assembly 03 is fixed to the inner wall of the outrigger 02 by rigid connection methods such as bolts, clamps or welding, so as to maintain the stability of the drive assembly 03 itself during the lifting action.

[0028] The drive assembly 03 provides vertical lifting power and can be one of a hydraulic rod, an electric push rod, or a screw lifting mechanism. The actuation output end of the drive assembly 03, such as the piston rod end, the push rod end, or the screw nut seat, is directly or indirectly connected to the fork arm 04.

[0029] The fork arm 04 is a fork-lifting component that directly supports goods. One fork arm 04 is provided on each support leg 02. The fork arm 04 is directly connected to the drive assembly 03, and the two fork arms 04 are parallel to each other in the horizontal direction. There is a gap between the two fork arms 04, which is used to place the pallet 05, and the two sides of the pallet 05 are supported on the two fork arms 04 respectively.

[0030] During the transportation of goods, the goods are placed on pallet 05, and the chassis body 01 moves to the front of pallet 05. At this time, the fork arms 04 on the support legs 02 are aligned with the two sides of the pallet 05. Then the chassis body 01 moves forward until the fork arms 04 are below the pallet 05. At this time, the fork arms 04 rise, lifting the pallet 05 and the goods together, and then they can be moved and transported through the chassis body 01.

[0031] In this embodiment, by fixing support legs 02 to the same side at both ends of the chassis body 01, and embedding the drive assembly 03 within the receiving space of the support legs 02, the fork arm 04 is directly installed inside the support legs 02 and connected to the drive assembly 03. The fork arm 04 is used to lift the pallet 05, and the drive assembly 03 drives the fork arm 04 to rise and fall vertically to achieve the raising and lowering of the pallet 05. Thus, the fork arm 04, as a fixed integrated part of the AGV body, does not need to be driven separately to the fork arm assembly placement location for mechanical docking and locking before handling operations. This saves the step of separating and docking the power drive part with the fork arm assembly in traditional solutions, thereby simplifying the operation process and improving overall transportation efficiency.

[0032] During transportation, this application directly transports the goods to the bottom of the pallet. By controlling the fork arm 04 to rise and lift the pallet and goods, transportation can be carried out directly.

[0033] In an optional embodiment, a guide assembly 06 is provided on the support leg 02, the guide assembly 06 is vertically fixed on the support leg 02, and the fork arm 04 is connected to the guide assembly 06.

[0034] In this embodiment, the guide assembly 06 is arranged along the height direction of the support leg 02. The fixed end of the guide assembly 06 is fixed inside the support leg 02 by bolts or welding, while the movable end extends out of the support leg 02 and is fixedly connected to the fork arm 04. The guide assembly 06 is used to provide guidance and lateral support for the fork arm 04 during vertical lifting, so that the fork arm 04 always moves along a preset vertical trajectory, avoiding swaying, twisting, or jamming caused by the shift of the center of gravity of the goods or the asynchronous movement of the drive assembly 03.

[0035] Please continue reading. Figure 5 In this optional embodiment, the guide assembly 06 includes a guide rail 07 and a slider 08. The guide rail 07 is vertically fixed on the support leg 02, one side of the slider 08 is slidably connected to the guide rail 07, and the other side of the slider 08 is fixedly connected to the fork arm 04.

[0036] In this embodiment, the guide rail 07 is a long strip-shaped guide component extending vertically. The guide rail 07 is fixed inside the support leg 02. A vertical hole is provided on the inner wall of the support leg 02 corresponding to the position of the guide rail 07. The slider 08 is located in the vertical hole, and one side of the slider 08 is movably connected to the guide rail 07, while the other side is fixedly connected to the fork arm 04. Specifically, one side of the slider 08 is provided with a sliding groove or rolling element that matches the cross-sectional shape of the guide rail 07, and it can be slidably connected to the guide rail 07. The slider 08 can slide freely in the vertical direction relative to the guide rail 07. The other side of the slider 08 is fixedly connected to the vertical plate 09 of the fork arm 04 by bolts or welding.

[0037] When the drive assembly 03 drives the fork arm 04 to rise and fall, the slider 08 moves up and down along the guide rail 07 together with the fork arm 04.

[0038] In this optional embodiment, the support leg 02 is provided with two guide components 06, which are located on both sides of the drive component 03.

[0039] Specifically, each leg 02 is equipped with two sets of guide components 06 consisting of guide rails 07 and sliders 08. Both sets of guide rails 07 are vertically fixed inside the leg 02 and are symmetrically arranged on the left and right sides of the drive component 03.

[0040] Both sets of sliders 08 have their fixed sides connected to the fork arm 04, so that the fork arm 04 is constrained by two symmetrical guide points during the lifting and lowering process. This can prevent the fork arm 04 from generating torque or tilting due to force on one side, and further enhance the parallelism and stability of the lifting and lowering movement of the fork arm 04.

[0041] Please continue reading. Figure 4 In an optional embodiment, the fork arm 04 includes a vertical plate 09 and a horizontal plate 10, the vertical plate 09 being connected to the drive assembly 03, and the horizontal plate 10 being horizontally disposed at the lower end of the vertical plate 09.

[0042] In this embodiment, the fork arm 04 specifically includes a vertical plate 09 and a horizontal plate 10. The horizontal plate 10 is perpendicular to the vertical plate 09 and connected to it. The horizontal plate 10 extends horizontally inward from the lower edge of the vertical plate 09, that is, it extends towards the other leg 02. The vertical plate 09 and the horizontal plate 10 can be integrally formed, such as by bending or casting, or they can be two independent plates joined together by welding or bolting.

[0043] The function of the cross plate 10 is to extend directly into the bottom of the side of the pallet 05. The upper surface of the cross plate 10 is used to support the crossbeams or bottom plate on the side of the pallet 05, thereby lifting the goods off the ground.

[0044] In an optional embodiment, the fork arm 04 is connected to the drive assembly 03 by one of welding, bolting, or hinge.

[0045] In an optional embodiment, a first drive wheel is provided at the bottom of the chassis body 01, and a second drive wheel is provided at the bottom of the outrigger 02. The first drive wheel is a swivel wheel.

[0046] In this embodiment, a first drive wheel is provided at the bottom of the chassis body 01, and a second drive wheel is provided at the bottom of the outrigger 02. The first drive wheel is a swivel wheel. The swivel wheel can turn accordingly, providing flexible directional adjustment capability.

[0047] Please continue reading. Figure 6 In an optional embodiment, the drive assembly 03 is connected to the fork arm 04 via a connector 11.

[0048] In this embodiment, the connector 11 can be made of metal plates, blocks or rods, and the metal part itself has a certain structural strength.

[0049] The drive assembly 03 is vertically installed in the space of the support leg 02. The output end of the drive assembly 03 is fixed to one end of the connector 11, and the other end of the connector 11 extends outward from inside the support leg 02 and is fixedly connected to the vertical plate 09 of the fork arm 04.

[0050] In an optional embodiment, the inner side of the support leg 02 is provided with a perforation that communicates with the receiving space; one end of the connector 11 is connected to the drive assembly 03, and the other end passes through the perforation and is connected to the fork arm 04.

[0051] In this embodiment, the perforation is a long strip-shaped through groove or rectangular opening extending in the vertical direction, and is opened on the side wall of the support leg 02 facing the fork arm 04. The length of the perforation needs to meet the requirements of the maximum lifting stroke of the fork arm 04, and the width is slightly greater than the thickness of the connector 11 to allow it to slide freely.

[0052] One end of the connector 11 is connected to the output end of the drive assembly 03 within the receiving space by bolts or pins, and the other end extends out to the outside of the support leg 02 after passing through the through hole, and is fixedly connected to the vertical plate 09 of the fork arm 04.

[0053] In an optional embodiment, the drive assembly 03 is one of a hydraulic rod, an electric actuator, or a lead screw.
