Cargo loading and unloading device and cargo loader

Abstract

The invention discloses a cargo loading and unloading device and a cargo loader. The cargo loading and unloading device comprises a support connected with a vehicle body, a transfer frame and a translation frame which are arranged in a spaced manner in the front-back direction of the vehicle body, and a cargo loading and unloading mechanism arranged on the translation frame and used for being connected with cargoes. A first connecting rod and a second connecting rod which are arranged in parallel are hinged between the transfer frame and the support to form a first parallelogram connecting rodstructure; and a first telescopic cylinder used for pushing the first connecting rod and the second connecting rod to swing front and back is connected between the support and the first connecting rod. A third connecting rod and a fourth connecting rod which are arranged in parallel are hinged between the translation frame and the transfer frame to form a second parallelogram connecting rod structure; and a second telescopic cylinder for pushing the third connecting rod and the fourth connecting rod to lift and swing back and forth is hinged between the second connecting rod and the third connecting rod. Accordingly, through the movement of the transfer frame and the translation frame in the front-back direction and the up-down direction of the vehicle body, efficient loading, unloading or transferring of batched goods can be achieved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a cargo handling device and a cargo handling vehicle. Background technique [0002] The forklift trucks in the prior art generally only have the function of fork loading, that is, loading and unloading goods with pallets. Since there is no cargo box to place the goods, they can only fork one goods for short-distance transshipment at a time, and a single transshipment batch of goods , back and forth forklift waste time, and not suitable for long-distance transportation. In addition, if a truck with a truck-mounted crane is used for cargo transfer, although it has a cargo box and can be transported, it can only lift the cargo, and cannot lift the cargo with a pallet (without a lifting interface), so it is not applicable. If the truck-mounted crane adopts a grab-shaped clamp, the surface is flat, and the boxes that cannot be clamped on the outer surface cannot be lift...
