Various types of battery replacing vehicles are released by part of the existing vehicle enterprises, and batteries of the types of battery replacing vehicles are usually arranged on a bottom frame of a vehicle, so that the operation is carried out from the bottom of the vehicle when the batteries are replaced, namely, the vehicle is lifted through facilities, the bottom frame is suspended, and then mechanical arms or operation trolleys are sent to the lower part of the frame to load and unload the batteries.
At present, the power station for replacing the automobile battery on the market is mainly divided into two facilities, namely a trench and a fixed lifting frame, as well as the original facility for maintaining and repairing the common automobile, wherein the two facilities are technically mature, but still have the following defects:
1. the dependence on the field is too strong, the occupied area is large, and the use is not flexible; since the trench or the fixed lifting frame is a ground fixed facility, the battery charging and storage and transportation facilities matched with the battery charging and storage and transportation facilities in the battery replacement station can only be built and bound with each other integrally, so that a relatively open field is required, and the trench or the fixed lifting frame is not suitable for being built in city centers with crowded traffic and short land or narrow underground garages and other areas.
2. Known fixed lifting frame often comprises a series of complicated and accurate mechanisms, cooperates together to accomplish a series of actions such as counterpoint, locking and lifting to the car, and overall structure is complicated, in case install on the spot accomplish just difficult dismantlement again and shift, needs professional to install, debug, and the price is expensive, and the equipment maintenance cost is high. Moreover, one set of mechanism only serves one automobile with a single specification, the application range is very limited, and the high-density layout cannot be realized due to the huge investment of the battery replacement station integrating part of automobiles and enterprises.
3. The inside only corresponds a motorcycle type usually of current power station of trading, does not have wheel base and wheel base problem when consequently the lifting counterpoint, if the demand of trading of all vehicles of will adapting to, the lifting device must increase a set of complicated mechanical structure and adapt to wheel base and wheel base, even if so still propose the accurate fixed station that can only stop into to the driver of fairly high driving technical requirement. For some drivers who are not skilled in driving technology, certain inconvenience is brought, so that the power changing fields need to be configured with professionals or adopt full-automatic parking systems, and consequently, the power changing efficiency is reduced.
The AGV dolly is the comparatively ripe haulage equipment that bears of present industry occasion application, and it has can remove by oneself and the characteristics of small and exquisite structure, carries on the lift drive arrangement who installs the high accuracy on the AGV dolly in the present trade, and the lifting is implemented to whole immigration car bottom. However, this kind of lifting device is limited to the lifting and moving of the vehicle, and cannot be used for replacing the battery or repairing the bottom of the vehicle, and has the following disadvantages:
1. the AGV dolly of present lifting device need remove to the frame bottom to the vehicle lifting operation, and itself and the lift drive device on it just occupied the activity space of the operation dolly that is used for next trading electricity and arm, leads to unable trading electricity.
2. If design according to present fork truck structure and trade the AGV dolly for electric, then AGV dolly self must bear the weight of car, and the AGV dolly is after holding up the vehicle simultaneously, and its bottom walking wheel also difficult avoid producing unstable removal, consequently need dispose the AGV dolly of very big load.
3. Because the forces in all directions of the bottom of the vehicle need to be borne and balanced, a supporting and balancing and stabilizing mechanism needs to be additionally arranged on the AGV trolley to provide stable supporting force, so that the whole mechanism of the lifting device is complex, the operation is inconvenient, and the manufacturing cost and the maintenance cost are relatively high.

When the lifting mechanism does not perform lifting operation and the AGV trolley 1 can freely walk, the bottoms of the four upright posts 13 of the support frame 2 are in a suspended state and do not contact the ground, as shown in fig. 1.
Referring to fig. 1 to 4, the lifting block 4 is located inside the rectangular frame. In this embodiment, each wheel support rod 5 extending from the bottom of the rectangular parallelepiped frame corresponding to the lifting block 4 is formed with an extending leg 11 in the same direction as the wheel support rod 5.
In this embodiment, the lifting driving device 3 is a telescopic motor, and is fixed on the inner side of the lifting block 4, and shares a shell with the lifting block 4, and the telescopic rod of the telescopic motor, namely the movable end, extends out of the top of the shell of the lifting block 4, and is riveted with the top plate 12 of the support frame 2, so that the connection with the support frame 2 is realized.
Referring to fig. 1 to 4, in this embodiment, a guide mechanism is installed between the lifting block 4 and the supporting frame 2 to guide and limit the lifting block 4 to be lifted relative to the supporting frame 2. The guide mechanism is specifically as follows:
support frame 2 adopts the cuboid frame as above-mentioned in this embodiment, all forms perpendicular guide way 9 between every pair of two pole settings 13 about it, and corresponds every side perpendicular guide way 9 on the shell of lifting piece 4 and all installs two rows of guide rollers 10, and these two rows of guide rollers 10 offset with two pole settings 13 of corresponding perpendicular guide way 9, and every row of guide rollers 10's quantity is two.
