Abstract
Description
Technical Field
[0001] This utility model relates to the field of material handling technology, and more specifically, to a material handling vehicle with a self-balancing function. Background Technology
[0002] In factories, handling and stacking goods is often an unavoidable operational process. Material handling operations frequently require moving items to higher levels, typically using manual methods to move goods onto shelves. However, this method is inefficient, labor-intensive, and inefficient, hindering cost control. Manual handling is also difficult for larger and heavier items. Therefore, the handling and stacking of large items generally requires the use of large handling equipment such as diesel forklifts. However, using such equipment requires significant space and presents considerable limitations.
[0003] AGV is an abbreviation for Automated Guided Vehicle, which generally refers to a transport vehicle equipped with electromagnetic or optical automatic guidance devices. It can travel along a prescribed guidance path and has safety protection and various transfer functions. AGV belongs to the category of wheeled mobile robots (WMR), also known as transfer robots. AGV is most often used in factories with a high degree of automation. However, existing AGV transport vehicles are often still in the form of traditional forklifts, which are difficult to handle the problem of stacking goods on high-rise shelves.
[0004] For example, CN210001540U discloses a double-mast stacker truck, including a power supply unit and a drive system powered by the power supply unit. The drive system includes at least a controller, a traveling unit controlled by the controller, and a hydraulic unit. A seat frame is provided at the front of the drive system. The seat frame includes a lifting plate, a frame, and load-bearing pulleys. A first lifting mast and a second lifting mast, driven by the hydraulic unit, are symmetrically arranged on the front and rear sides of the lifting plate. The lifting plate is equipped with horizontally bidirectional forks and a motor and sprockets that drive the forks. The frame surrounds the lifting plate, and the load-bearing pulleys are located at the bottom of the frame and driven by the traveling unit. However, when the forks are inserting or removing goods, if the ground is uneven, the goods are prone to displacement on the forks, posing a risk of falling and seriously affecting the yield rate, thus having significant limitations.

A support plate is movably mounted on the sliding frame, and the support plate can rotate along its central axis. The support plate can always remain horizontal under the drive of an adjustment component. A fork is also mounted on the support plate, and the fork can extend and retract under the drive of a drive component.
[0008] Preferably, the adjusting assembly includes at least one pin respectively disposed on the support plate and the sliding frame, wherein one pin is pivotally connected to the housing of the push cylinder, and the other pin is pivotally connected to the cylinder shaft of the push cylinder;
