When the two converters 1 simultaneously drive the respective driving connecting rods 1.10 to move, the driven connecting rod 3.1 fixed with the first connecting rod 4.3 moves, and the driven connecting rod 3.1 drives the first connecting rod 4.3 to move; the first connecting rod 4.3 drives the first connecting shaft 4.1 to rotate; the first connecting shaft 4.1 transfers the moving direction of the first connecting rod 4.3 to the second connecting rod 4.4 after being converted; the second connecting rod 4.4 drives the second connecting shaft 4.2 to rotate; the second connecting shaft 4.2 transfers the movement direction of the second connecting rod 4.4 to the movement of the third connecting rod 4.5 after being converted; the third connecting rod 4.5 drives the driven connecting rod 3.1 fixed with the third connecting rod 4.5 to move; at this time, the other converter 1 simultaneously drives the corresponding driving connecting rod 1.10 and the corresponding driven connecting rod 3.1 to move, and the moving directions of the driven connecting rods 3.1 driven by the two converters 1 are consistent, so that each driven connecting rod 3.1 can simultaneously move and drive each rotary lock head 3.2 to simultaneously rotate, and locking and unlocking actions are performed. When one of the two converters 1 does not normally drive the driving connecting rod 1.10 to move, the self structure of the converter 1 generates self-locking, and even if one converter 1 can normally work, the rotating lock head 3.2 cannot be pushed to rotate, so that the whole connecting rod structure 6 can be locked to keep the current state unchanged as long as one converter 1 fails. The whole safety of the connecting rod structure 6 can be ensured by the structure, and the following conditions are avoided: when one of the converters 1 is normal, and the other converter 1 fails, the normal converter 1 opens one of the locking assemblies 3, the locking assembly 3 connected with the failed converter 1 is not jammed, one side of the vehicle carrier plate 5 locked with the lifting frame 2 is unlocked, and the other side of the vehicle carrier plate 5 is locked, so that the vehicle carrier plate 5 is seriously inclined, and a vehicle above the vehicle is turned on one side and overturned, thereby causing serious loss. The scheme in the embodiment has no problem, namely, all the rotary lock heads 3.2 are unlocked simultaneously, or all the rotary lock heads 3.2 are locked simultaneously, and the state that one side of the rotary lock head 3.2 is locked and the other side of the rotary lock head 3.2 is unlocked does not exist.
The utility model has the advantages that: the relative translation of the vehicle carrier plate and the lifting frame can be converted into the rotation of the rotary lock head, so that the locking and unlocking of the vehicle carrier plate and the lifting frame are realized; the vehicle support plate is locked by adopting a plurality of rotary lock heads, the locking structure is reliable, and the locking and unlocking processes are quick; all the lock heads are mutually linked, so that the safety is high; the unlocking and locking relation is only related to the contact relation between the telescopic rod and the vehicle carrier plate, so that the stability and the reliability are high, and the interference of other factors is not easy to occur; the overall structure of the converter is compact.
