Novel stable self-elevating fork truck

Abstract

The invention relates to the field of mechanical equipment, in particular to a novel stable self-elevating fork truck. According to the technical scheme, the novel stable self-elevating fork truck comprises a portal, truck legs, a tray frame assembly and a battery, wherein the tray frame assembly ascends and descends on the portal through a lifting device. The lifting device comprises a cylinder, a piston rod and a pump station. The pump station, the cylinder and the battery are all arranged at the root position of the tray frame assembly. The piston rod downwards ejects out and is connected with the portal. The novel stable self-elevating fork truck is simple and practical in structure, implementing is facilitated, on one hand, the gravity center of a truck body of the fork truck is balanced, and the tipping risk is reduced; and on the other hand, the truck weight is reduced, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a novel stable self-elevating stacker. Background technique [0002] Self-elevating stacker is a common equipment in the field of logistics. It is a variety of wheeled handling vehicles for loading and unloading, stacking, short-distance transportation, and heavy object handling of palletized goods. It is widely used in ports, stations, airports, and freight yards. , factory workshop, warehouse, distribution center and distribution center, etc., and can enter the cabin, carriage and container for loading, unloading and handling of palletized goods. It is an indispensable equipment for pallet transportation and container transportation. [0003] A common stacker, such as a stacker structure disclosed in the Chinese patent document CN104909304A, includes a door frame assembly, a car leg, a pallet rack assembly, a handle, a lifting device and electrical components, and the user c...

AI Technical Summary

Problems solved by technology

[0004] However, this structure also has many shortcomings. For example, the stacker will place all or most of the lifting device and electrical components at the bottom of the mast. In this way, when the empty car is self-lifting, the center of gravity of the whole car is behind, or there is a backward tilt. danger

The existing self-elevating stacker part increases the counterweight at the front end of the fork to avoid backward tilting, but the weight of the whole vehicle will increase a lot, which will affect the operability of the whole vehicle and reduce work efficiency

There are also self-lifting stacker parts that change the counterweight at the front end of the fork to a weight type. When in use, it is placed directly on the front end of the fork. When not in use, it must be placed aside and cannot be lost. When the vehicle is transferred, it must be transferred together. , so that not only the operation is troublesome, but the loss of weights will also affect the work of the vehicle
