The hoisting tool provided by the embodiment of the utility model is suitable for vehicles with the battery box body 5, and can be particularly used in electric vehicles such as pure electric vehicles, extended range power vehicles or plug-in hybrid vehicles.

It is convenient to understand that the battery replacement device according to the present utility model may refer to an automated system for replacing a battery box of an electric vehicle or other devices, which can automatically replace the battery box 5 to extend the driving range of the vehicle without waiting for battery charging.

However, the distance between the two beams on the a battery box 1 and the two beams on the B battery box 3 is different, so that the lifting mechanism suitable for the a battery box 1 cannot be used for grabbing the B battery box 3, and the lifting mechanism suitable for the B battery box 3 cannot be used for grabbing the a battery box 1. Therefore, for different vehicles equipped with battery boxes 5 of different sizes, different types and even different factories, the power exchange process is difficult, the types of vehicles which can be served by the power exchange station are limited, and the travel convenience of drivers and passengers is reduced.

The frame 2 of the battery box 5 is a general fixing structure, usually a square frame 2, and is composed of four linear trusses which are relatively parallel and equal, and a gap is formed between the frame and the top surface of the battery box 5. Since the fixing mechanism 7 is used for being mounted on the frame 2, and the supporting mechanism 6 is mounted on the fixing mechanism 7, the hoisting mechanism acts on the battery box 5 to realize the power exchanging operation.

Wherein each support means 6 is mounted on every two oppositely arranged fixing means 7 can be understood as: a plurality of fixing mechanisms 7 are respectively provided on two trusses disposed opposite to each other in the frame 2 so that both ends of the supporting mechanism 6 can be respectively mounted on the two trusses disposed opposite to each other, in other words, when the two trusses correspond to both long sides of the square frame 2, the vertical length of the supporting mechanism 6 is the length of the square frame 2, and when the two trusses correspond to both wide sides of the square frame 2, the vertical length of the supporting mechanism 6 is the width of the square frame 2.

The plurality of supporting mechanisms 6 are parallel, which can be understood as that the arrangement space of the plurality of fixing mechanisms 7 on one truss is equal to the arrangement space of the plurality of fixing mechanisms 7 on the other truss, when the supporting mechanisms 6 are installed on the two opposite fixing mechanisms 7, the distance between the two supporting mechanisms 6 is equal in width, so that the supporting mechanisms can be adapted to the fixedly arranged hoisting mechanisms, for example, when the hoisting mechanisms are in a double-row lifting hook 4 structure, as shown in a schematic diagram of an installation structure of one hoisting mechanism and the battery box 5 in fig. 9, the distance between the two lifting hooks 4 is fixed, and then the two lifting hooks can be respectively connected to any positions of the two adjacent supporting mechanisms 6, thereby achieving stable assembly.

When the fixing mechanism 7 and the supporting mechanism 6 are mounted, the positions of the second mounting holes may be opposed to the positions of the corresponding first mounting holes 711 in different longitudinal directions, and the first mounting holes 711 and the second mounting holes may be mounted by passing through the mounting bolts 8. In some embodiments, the first mounting hole 711 of the fixing mechanism 7 on the same truss is closer to the fixing mechanism 7 adjacent thereto, and when the second mounting hole is assembled with the first mounting hole 711, the distance between the mounted support mechanism 6 and the adjacent support mechanism 6 is shorter, and vice versa.
