The floor device for performance verification of a piggyback transport vehicle of any one of claims 1 to 4, wherein said unlocking mechanism comprises a support beam, a first unlocking block and a second unlocking block, said first unlocking block and said second unlocking block being mounted to said support beam, said first unlocking block being configured to unlock the rotation of said middle rotating frame so as to allow said middle rotating frame to be in a rotatable state, said second unlocking block being configured to unlock the lock between said middle rotating frame and said end frame so as to allow said middle rotating frame to be in a raisable state.
6. The floor apparatus for performance verification of piggyback transport vehicles according to claim 5, wherein a first guide structure is provided between said support beam and said underframe mechanism to guide the vertical lifting of said support beam.
7. The floor apparatus for performance verification of piggyback transport vehicles according to any one of claims 1-4, wherein a second guide structure is provided between said support frame and said chassis mechanism to guide the vertical lifting of said lifting mechanism.
8. The ground apparatus for performance verification of piggyback transport vehicles according to any one of claims 1-4, wherein said side support assembly comprises a support base and at least two roller assemblies disposed on said support base, each of said roller assemblies being mounted on the top surface of said support base along the turning trajectory of said middle swivel frame.
9. The floor apparatus for performance verification of piggyback transport vehicles according to any one of claims 1-4, wherein said drive mechanism includes two drive groups, one for driving rotation of said central rotating frame from an initial position to said loading and unloading position, the other for driving rotation of said central rotating frame from said loading and unloading position back to said initial position; each driving group comprises two driving parts, each driving part comprises a winch supporting seat and a winch arranged on the winch supporting seat, and a rope wound on the winch is used for being connected with the middle rotating frame so as to apply force to the end part of the middle rotating frame.
10. The floor apparatus for piggyback transport performance verification of claim 9 wherein said drive mechanism further comprises a load cell for measuring the amount of drive force applied by said winch to said central rotating frame.
11. The ground device for piggyback transport performance verification of any one of claims 1 to 4, further comprising a first jacking portion for driving said unlocking mechanism to vertically lift and a second jacking portion for driving said lifting mechanism to vertically lift.
