Description

A mechanism for extracting and transferring electric boxes from chassis-type commercial vehicle battery swap stations

Technical Field

The utility model relates to the technical field of new energy commercial vehicle battery swap stations, and in particular to an electric box extraction and transfer mechanism for chassis-type commercial vehicle battery swap stations.

Background Art

As one of the efficient ways to supplement the power of commercial vehicles, the automatic battery replacement of new energy commercial vehicles can effectively solve the pain points of commercial vehicle charging spaces, large battery capacity, and long charging time. At present, domestic new energy commercial vehicle battery replacement stations are in a rapid development stage. At present, the market has been rapidly put into the market and operated by backpack-type new energy commercial vehicle battery replacement stations. However, chassis-type commercial vehicle battery replacement stations are still in the initial stage, and the battery replacement method is still in the stage of exploration, research and development, and the profit model is not outstanding compared to backpack-type new energy commercial vehicle battery replacement stations.

At present, several key issues that need to be solved in the design and construction of chassis-type commercial vehicle swap stations are:

One is that it occupies a large space. The chassis battery swap previously had a multi-bin and two sets of stacking cranes structure, which resulted in a huge space occupation at the station site and low utilization of the space on the second floor of the battery swap station.

The second is the accuracy of battery swapping. From the perspective of all operating battery swapping stations, the battery swapping control accuracy controlled by the magnetic grating may occasionally fail to read the magnetic grating, causing the battery swapping machine to not be able to find the origin; the battery swapping control accuracy controlled by laser ranging will increase costs; the battery swapping control accuracy controlled by scanning QR codes may cause the QR code to be covered with dust for a long time or faded and cannot be recognized, resulting in misjudgment of the position.

The third is the efficiency of battery replacement. The chassis-type commercial vehicle battery box is generally composed of three parts, with a total weight of about 4.5 tons. The two sets of pallet cranes are operated with three batteries each time they are replaced, and they only operate once, which causes the overall load of the pallet crane to be too large, making the operation speed of the pallet crane relatively slow, resulting in low utilization of the pallet crane. How to improve the utilization rate of chassis-type commercial vehicle battery replacement stations and the stability of battery replacement is also one of the important research topics of current battery replacement stations.

103. Realize the function of power supply during the operation of the electrical box extraction and transfer mechanism.

The double-row fork telescopic device 8 and the fork multi-position online detection device 9 are combined into a fork telescopic assembly.

During the use of the utility model: after the power box runs to the cache station, the PLC main control room sends instructions to the control system 5 to inform the whole machine how to take the power box. The process is as follows: the power box extraction and transfer mechanism runs to the cache station on the whole machine walking track 2 through the whole machine walking wheel 3, and the walking positioning device 4 re-judges whether the whole machine is in place. The double-row fork telescopic device 8 extends to take the power box, and the fork multi-position online detection device 9 determines whether the fork is in place. The lifting device 6 begins to lift the power box out of the cache station. The lifting positioning device 7 informs the whole machine control system 5 of the current position of the lifting device in real time. The double-row fork telescopic device 8 retracts the power box to the original position of the whole machine.

The PLC main control room continues to send instructions to the whole machine control system 5 to inform how the electric box is put into the electric box storage system. The process is as follows: the whole machine travel wheel 3 travels on the whole machine travel track 2 to the corresponding electric box storage system position. The whole machine control system 5 combines the lifting positioning device 7 to make a double judgment to let the lifting device 6 lift to the appropriate position. The double-row fork telescopic device 8 extends into the electric box storage system with the electric box. The whole machine lifting device 6 descends to a certain height to allow the electric box to slowly contact the electric box storage rack. The lifting device 6 continues to descend to a certain height until the double-row fork telescopic device 8 is separated from the electric box. The double-row fork telescopic device 8 begins to retract and retracts to the original position of the whole machine.

After placing the battery box on the storage rack, the battery box extraction and transfer mechanism starts to take the full battery box to the buffer station. The process is exactly the opposite of the process of placing the battery box on the battery rack by the battery box extraction and transfer mechanism, so it will not be repeated.

The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
