technical field

The invention relates to the technical field of forklift trucks, in particular to a battery replacement device of a forklift truck.

Background technique

Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles for loading, unloading, stacking and short-distance transportation of palletized goods. Forklifts are usually driven by fuel engines or batteries. Forklifts can usually be divided into three categories: internal combustion Forklifts, electric forklifts and storage forklifts, electric forklifts refer to forklifts that operate on electricity, most of which work for batteries. In loading and unloading operations, the battery is one of the batteries. Its function is to store limited electrical energy and use it in a suitable place. The battery is an important part of the electric forklift. During the operation of the electric forklift, the battery will continue to charge Therefore, it is necessary to charge the battery. Due to the long charging time of the battery, in order to improve the work efficiency, the battery is usually replaced to ensure the continuous operation of the forklift. At present, the common battery replacement methods are usually as follows:

Method 1: Lift the used battery vertically with the help of a spreader, remove the battery from the right side of the forklift, and place it on a special tool such as a pre-prepared pallet, then transfer the spreader to the spare battery, and Hoist it into the frame;

Method 2: Design the frame of the forklift as a structure with an open bottom and an open right side. When replacing the battery, you need to use another forklift or special tool to remove the used battery, and then move the spare battery into the frame of the forklift. ;

Method 3: Design the frame of the forklift as a structure with rollers at the bottom and an open right side. When replacing the battery, you need to use a special tool to remove the used battery from the frame, and then move the spare battery into the frame of the forklift. Inside;

The fourth method is to arrange the battery directly at the rear of the forklift. When replacing the battery, lift the used battery directly from the rear with the help of a spreader, and then lift the spare battery to the rear of the forklift. When replacing the battery for the forklift, Usually, external tools are needed to complete the battery replacement, such as hoisting equipment, other forklifts and other auxiliary tools. When replacing the battery, a large working space is required. When the working space is insufficient, it will bring greater work to the operation It is inconvenient, and the operation time is long, the operation method is complicated, and the efficiency of replacing the battery is low. In addition, the battery is prone to tilt and fall during the operation, which has a great potential safety hazard.

For example, Chinese Patent Bulletin No. CN105399003A provides a battery replacement device for a forklift, which is basically described as: a trolley including a mobile battery, the trolley includes a tray on which the battery is placed, and the tray is provided with legs at the bottom, The upper end of the support leg is pivotally connected to the bottom of the tray, the lower end of the support leg is provided with casters, the support leg is connected with a link mechanism, the support leg can be controlled by the link mechanism to fold, and the support leg also It can be deployed to a vertical position. The invention pushes the trolley and the battery on the trolley into the forklift together to replace the battery, which is convenient for the staff to use and improves the efficiency of battery replacement, but the practicability of the device is poor, because the trolley is used for In the same Amgen forklift, the gap in the forklift becomes larger, which requires the improvement of the stability of the battery fixing, so that the battery will not shake when the forklift is moving, and some structures need to be added to maintain it. The stable structure of the trolley and battery, if popularized, will increase the cost a lot, and will increase the overall weight of the device, resulting in the forklift requiring more power when starting and running, speeding up the speed of battery replacement, thereby reducing the cost of the forklift. usability of the device.
