In the initial state, the goods carrying rack 1 and the moving rack 5 are in an overlapped structure, and the fork truck pushing handle 3 drives the moving rack 5 to send the goods carrying rack 1 to the lower part of the supporting plate of a required container. Then, the hydraulic assembly 4 of the forklift is fed with oil from the oil cylinder 15, so that the piston rod 12 lifts the cargo lifting frame 11, the cargo carrying frame 1 forks the cargo box and the pallet to be separated from the ground, and then the cargo box is carried by pulling or pushing the pushing handle 3 of the forklift.

When the forklift reaches a compartment, the load carrying rack 1 is lifted to a height position higher than the bottom of the compartment, then the container and the supporting plate are conveyed into the compartment through the forklift push handle 3, then the load carrying rack 1 is descended to enable the supporting plate to be in contact with the bottom of the compartment, then the oil cylinder 15 upwards lifts the forklift bottom plate 16 along the piston rod 12 to drive the moving rack 5 and the forklift hydraulic component 4 to be lifted, and meanwhile, the fork rod pull handle 23 is pulled, so that the moving rack 5 slides to the rear of the forklift hydraulic component 4. When the bottom plate 16 of the forklift is lifted to the moving frame 5 to be attached to the goods carrying rack 1, the fork rod pull handle 23 is pushed to enable the moving frame 5 to slide to the front of the hydraulic component 4 of the forklift, then the oil cylinder 15 is used for lifting oil, so that the piston rod 12 is used for lifting the goods carrying lifting rack 11, and the goods carrying rack 1 is used for forking the goods box and the supporting plate to be separated from the end face of the carriage and transporting to a specified position.

After the container and the supporting plate are conveyed to the designated position, the loading rack 1 descends to enable the supporting plate to be in contact with the bottom of the compartment, and then the fork truck push handle 3 is pulled to finish the separation process of the loading rack 1 and the supporting plate. When the electric forklift goes down from the carriage in no-load, the load carrier 1 descends to contact with the end face of the carriage, the fork rod pull handle 23 is pulled at the moment, the moving frame 5 slides to the rear of the forklift hydraulic component 4, then the oil cylinder 15 moves downwards along the piston rod 12, the forklift bottom plate 16 drags the moving frame 5 and the forklift hydraulic component 4 to descend, and meanwhile, the fork rod pull handle 23 is pushed to enable the moving frame 5 to slide to the front of the forklift hydraulic component 4. When the movable frame 5 falls to the ground, the oil cylinder 15 stretches the piston rod 12 to enable the loading frame 1 to be separated from the end face of the carriage, then the forklift push handle 3 is pulled to enable the loading frame 1 to be separated from the carriage, and finally the oil cylinder 15 drives the piston rod 12 to retract to the initial state to complete the whole loading and unloading carrying process.

The hydraulic reversing valve 35, the rotary valve 36, the pressure reducing valve 37 and the overflow valve 38 are integrally placed on the oil tank 29 by adopting a valve block, so that the connecting distance of pipelines is reduced, and the control stability of an oil way is improved. The motor 28 drives the hydraulic pump 30 to suck oil from the oil tank 29 to discharge the pressure oil, and the pressure oil enters each valve to supply oil to the oil cylinder 15. And the process of getting on and off the electric forklift and the process of transporting goods are controlled by the hydraulic reversing valve 35, the rotary valve 36, the pressure reducing valve 37 and the overflow valve 38. The operating oil is cooled by a cooler 40 and filtered by an oil return filter 39. The hydraulic change valve 35 realizes the up-and-down lifting process of the oil cylinder 15 and the piston rod 12 on the electric forklift by changing the steering of the change valve 36. When the load carrier 1 carries goods, the pressure maintaining ball valve 34 realizes the function of maintaining the oil way locking of the oil cylinder 15, and the load carrier 1 is ensured not to actively descend in the carrying process.

In conclusion, the multifunctional portable electric forklift has the advantages of high structural strength, complete functions, stable and reliable operation, convenience in operation and wide application. The problem of the goods transport difficulty of getting on the bus or getting off from the bus is solved. The effects of convenient loading and unloading of light-load goods and vehicle-mounted forking are realized. The working strength of carrying light-load goods is reduced, and potential safety hazards in the carrying process are avoided.
