Description

Technical Field

[0001] The invention relates to the technical field of AGV trolleys, and in particular to an anti-rollover material receiving device based on an AGV trolley. Background Art

[0002] An AGV cart is a transport vehicle equipped with an automatic guidance device such as an electromagnetic or optical device, which can travel along a specified guidance path and has safety protection and various transfer functions. When receiving materials, some AGV carts first move as a whole to the bottom of the material, and then lift the material through the lifting device on the AGV cart to achieve material reception. However, this method has certain limitations. If the material is placed directly on the ground, after clamping the material, the overall center of gravity is on the outside of the cart, which is prone to tipping over during driving. Patent documents have now been issued to improve this.

[0003] Chinese patent CN217051512U relates to a material receiving device based on an AGV trolley, including a vehicle body, on which a transverse movement device, a lifting device and a clamping device are arranged, the transverse movement device including a first motor, a lead screw, a guide rod and a moving seat, both ends of the lead screw are rotatably connected to the vehicle body, both ends of the guide rod are fixedly connected to the vehicle body, the moving seat is threadedly connected to the lead screw, the moving seat is slidably connected to the guide rod, the first motor is arranged on the vehicle body, and the output shaft is connected to the lead screw. In the present invention, by arranging a transverse movement device, when receiving materials, the clamping device is moved to the outside of the vehicle body to facilitate the clamping device to clamp the materials. After the material receiving is completed, the clamping device is moved to the top of the vehicle body by the transverse movement device, so that the vertical line of the center of gravity of the device is located within the upper surface range of the vehicle body to prevent tipping.

[0004] Although the above patent prevents tipping by placing the vertical line of the center of gravity of the device within the upper surface of the vehicle body, when the clamping device is extended to clamp the material, the overall center of gravity will move to the left, causing the center of gravity of the AGV to change, making the AGV prone to tilting and tipping, affecting the normal use of the AGV.
