Abstract

The utility model discloses an unhooking robot trolley and an arrangement structure thereof. The unhooking robot trolley comprises a driving platform, an unhooking device, a speed sharing device and a state data generating, collecting, processing and transmitting device, the driving platform comprises a wheel assembly and a platform body framework connected to the upper portion of the wheel assembly. The unhooking device, the speed sharing device and the state data generating, collecting, processing and transmitting device are all arranged on the platform body framework. The unhooking device is used for clamping the hook lifting rod and carrying out unhooking operation; the common-speed device is used for enabling the unhooking robot trolley and the truck to run at the same speed; the state data generating, collecting, processing and transmitting device is used for collecting, processing and transmitting state data generated by the unhooking robot trolley and receiving a control instruction, and autonomous driving and operation control of the unhooking robot trolley are achieved. The wheel assembly comprises a trolley track, track wheels arranged on the trolley track and connected to the lower portion of the platform main body framework, and a driving transmission device.
