Description

Technical Field

[0001] The utility model belongs to the technical field of logistics robots, and in particular relates to a lifting robot used for logistics. Background Art

[0002] While some existing logistics robotics technologies are capable of autonomous navigation and material handling, they still face numerous deficiencies in the unloading process. For example, some robots can only carry materials to designated locations but cannot automatically unload them, requiring manual assistance. This not only reduces operational efficiency but also increases labor costs. Other robots, while designed with automated unloading capabilities, often have complex structures, high maintenance costs, and are prone to instability and failure in practice.

[0003] Furthermore, logistics robots must maintain sufficient stability during operations, especially when unloading, to prevent swaying or tilting due to the weight of the materials, ensuring safe and accurate operation. Existing logistics robots often employ methods such as adding counterweights and optimizing structural designs to achieve stability, but these approaches often increase the robot's overall weight and cost, and compromise its mobility. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a lifting robot for logistics, which solves the problem that existing logistics handling robots often still need manual assistance during unloading and have low stability during unloading.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a lifting robot for logistics, comprising an AGV trolley base, wherein wheels are installed at the bottom of the AGV trolley base, and two groups of support assemblies are relatively installed on the bottom side of the AGV trolley base, wherein the support assembly includes a connecting plate, wherein the connecting plate is rotatably connected to a connecting rod one, a connecting rod two and one end of an electric push rod through a pin shaft, and the other ends of the connecting rod one, the connecting rod two and the electric push rod are rotatably connected to a moving frame through a pin shaft, the connecting rod one and the connecting rod two are arranged parallel to each other, the connecting plate and the moving frame are arranged parallel to each other, a scissor-type lift is installed on the AGV trolley base, a lifting platform is installed on the top of the scissor-type lift, and a unloading assembly is installed on the lifting platform, the unloading assembly includes a push plate, the bottom end of the push plate is connected to the connecting frame, the connecting frame is slidably installed on the lifting platform, the bottom end of the connecting frame is connected to a moving plate, the moving plate is threadedly connected to a screw and slidably connected to a guide rail, the screw is rotatably installed on the support seat and transmission-connected to a motor, and the support seat and the motor are installed on the lifting platform.

[0006] The beneficial effects of the present invention are as follows: the material is pushed by the use of the unloading assembly, thereby realizing automatic, rapid and stable unloading of the material; the support of the support assembly with a parallelogram connecting rod structure provides stable support during unloading, thereby ensuring the safety and accuracy of the operation.

[0007] In order to ensure the stability of the support assembly for the overall support of the device;

[0008] As a further improvement of the above technical solution: the movable frame is an angle iron structure.

[0009] The beneficial effect of this improvement is that when one side wing plate of the movable frame moves parallel to the connecting plate under the push of the electric push rod and the limitation of connecting rod 2 and connecting rod 1, the other side wing plate of the connecting plate keeps moving parallel to the contact surface of the wheel, and then rests on the contact surface of the wheel to provide stable support for the device.

[0010] In order to ensure the supporting strength of the mobile frame;

[0011] As a further improvement of the above technical solution: a rib plate in the form of a triangular plate is welded between the two wing plates of the movable frame.

[0012] The beneficial effect of this improvement is that the ribs can effectively improve the supporting strength of the mobile frame.

[0013] In order to make the mobile rack move stably;

[0014] As a further improvement of the above technical solution: the connecting rod 2 has the same structure and size as the connecting rod 1, and the supporting assembly is installed on two opposite sides of the AGV trolley base.

[0015] The beneficial effect of this improvement is that the parallelogram connecting rod structure composed of the connecting plate, the first connecting rod, the second connecting rod and the movable frame can be stably telescopically folded under the drive of the electric push rod.

[0016] In order to ensure the stability of unloading materials;

[0017] As a further improvement of the above technical solution: a sliding groove for sliding connection to the connecting frame is provided on the lifting platform.

[0018] The beneficial effect of this improvement is that, driven by the motor, the connecting frame can slide stably in the sliding groove, thereby driving the push plate to move and complete unloading.

[0019] In order to ensure the stability of the moving plate;

[0020] As a further improvement of the above technical solution: the guide rail is a T-shaped guide rail, and the lead screw is arranged parallel to the guide rail.

[0021] The beneficial effect of this improvement is that under the limit support of the guide rail and the drive of the lead screw, the movable plate can move stably on the lifting platform.

[0022] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

The mobile frame 64 is an angle iron structure. When the electric push rod 65 pushes and the connecting rod 2 63 and the connecting rod 1 62 limit the side wing of the mobile frame 64 to move parallel to the connecting plate 61, the other side wing of the connecting plate 61 keeps moving parallel to the contact surface of the wheel 2, and then rests on the contact surface of the wheel 2 to provide stable support for the device. A triangular plate rib 66 is welded between the two wing plates of the mobile frame 64. The rib 66 can effectively improve the supporting strength of the mobile frame 64. The structure of the connecting rod 2 63 and the connecting rod 1 62 The support assembly 6 is of the same size and is installed on opposite sides of the AGV trolley base 1.
