Description

Technical Field

[0001] The utility model relates to a lifting type cargo fork loader, belonging to the technical field of lifting type cargo fork loader. Background Art

[0002] In the field of production and logistics, the loading and unloading of goods has always been a labor-intensive process. The mechanization and automation of the loading process has become a research hotspot.

[0003] Existing automatic loaders mainly include two categories: one is a truss-type loader. When loading, the truck is driven under the truss, and the loading is carried out by a three-axis moving loading robot with the help of a visual system. This loading method has a complex system, high cost, and low loading efficiency. Moreover, this loading method is generally suitable for bagged materials, and cannot be used for loading stacked materials on pallets; the other is a push-plate conveyor-type loader. This loading method is to place the loading and conveying mechanism on a lifting platform. When loading, the truck is parked next to the loader, and the loading and conveying mechanism moves up and down with the lifting platform to adjust the height between the conveying mechanism and the bottom of the carriage, and the materials are pushed into the carriage by the push plate. However, this loading method generally only pushes the materials to the entrance of the carriage, and then pushes them into the carriage by manual or other unloading devices. It is also not convenient for loading heavier stacked materials.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0012] Furthermore, a fork push plate is fixed to the rear end of the fork assembly, and the fork forward conveying chain is connected to the fork push plate.

[0013] Furthermore, the upper loading frame is also provided with a plurality of pallet forward conveying chains, and both ends of the pallet forward conveying chains are driven by sprockets.

[0014] Furthermore, a large gear is fixedly mounted on the lower surface of the upper frame, and a driving gear is mounted on the lower frame. The driving gear is driven by a motor, and the large gear is meshed with the driving gear for transmission.
