Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and more specifically, to a heavy-duty pallet elevator for docking with an AGV. Background Technique

[0002] For projects using AGVs to pick up and place goods for inbound and outbound operations, considering the stability of the AGV during travel, the center of gravity of the AGV should be low, so the height of the AGV body should be low. However, due to the limitations of its own structure, the lowest position for the inbound and outbound stacker to pick up and place goods is higher than the height of the AGV body. To meet the on-site application requirements, there are hydraulic lifting conveyors in the industry, and gantry elevators are also used to compensate for the difference in height between the AGV body and the lowest pick-up and placement height of the stacker.

[0003] After retrieval, the existing patent (Publication No.: CN 220951027 U) discloses a heavy-duty pallet elevator for docking with an AGV. This heavy-duty pallet elevator for docking with an AGV can offset half of the weight of the lifted goods by using a counterweight assembly, enabling a motor with the same power and speed ratio to lift nearly twice the weight of goods; for the lifting of heavy goods, it can reduce the impact on the drive mechanism when the motor starts, making the lifting more stable, and the equipment more stable, reliable, and durable; moreover, a low-power motor can reduce the energy consumption of the equipment, save energy, and reduce unnecessary expenses.

[0004] However, in the above solution, there are still certain deficiencies.
