Single-drive electric forklift truck frame

Abstract

The invention discloses a single-drive electric forklift truck frame. The single-drive electric forklift truck frame comprises a frame main body; a cavity for storing a storage battery is arranged in the frame main body; and an opening is formed in one side of the cavity. The single-drive electric forklift truck frame is characterized in that a notch which communicates with the cavity is formed in the bottom plate of the cavity, symmetric shelves which are used for supporting the storage battery are reserved on the front side and the rear side of the bottom plate of the cavity, the notch and the opening of the cavity are positioned in the same side, at least one side, which is close to the opening of the cavity, of the frame main body is in shaft connection with a battery stopper; a bearing plate which bears the storage battery is arranged on the frame main body; an opening through which the storage battery can enter and exit is formed in the bearing plate; and channel steel is arranged on the inner side of the bearing top plate. The single-drive electric forklift truck frame has the advantages that the arrangement position of the storage battery is low, and stability of a forklift is good; and the cavity communicates with the ground, a large tool is not required, and the storage battery can be taken out from the side surface by a manual hydraulic vehicle, and is convenient to change; and by model selection of the bearing plate and the channel steel, requirements on bending resistance of frames with different tonnages can be met, and the universality is high.

Description

technical field [0001] The invention relates to the field of electric forklifts, in particular to a single-drive electric forklift frame. Background technique [0002] As a loading and unloading tool with large turnover and high efficiency, forklift can be used for loading and unloading, stacking and short-distance transportation. With the rapid development of my country's high-tech industry, forklifts are more and more widely used in stations, ports, freight yards, warehouses and workshops. At present, electric forklifts generally use batteries as energy sources to drive forklifts to perform operations. [0003] A traditional single-drive electric forklift is equipped with a drive system consisting of a drive axle, a reducer, and a drive motor at the front of the frame, the battery is arranged at the upper middle of the vehicle body, and the pump motor and fuel tank are arranged at both sides of the middle or at the rear of the middle. , the steering axle and counterweigh...

Problems solved by technology

[0004] On the one hand, the above-mentioned structure makes the arrangement position of the battery relatively high, resulting in a high center of gravity of the electric forklift body, which affects the stability of the electric forklift

Specifically, it affects the lateral stability of the electric forklift when it is working, making it easy to rollover when the electric forklift is turning; it affects the longitudinal stability of the electric forklift when it is working, so that the maximum load that the electric forklift can fork is reduced

[0005] On the other hand, in the above structure, a bottom plate is welded under the battery, and reinforcing ribs are arranged on the bottom plate as a support. Therefore, when it is necessary to install or replace the battery, it is often necessary to use a large hoisting device to lift the battery or use a special tool to insert and remove the battery. It is very inconvenient and has high requirements for supporting professional equipment and tools, which is difficult for many small enterprises to meet

[0006] In addition, if the above-mentioned structure is to be applied to single-drive electric forklifts of different tonnages, it is necessary to adjust the size and structure of the frame including side panels, bottom plates, ribs, and many other components, which is quite cumbersome and makes traditional single-drive electric forklifts universal.
