Flat car for steering transportation of railway steel rails

The utility model provides a flat car for steering transportation of railway steel rails, belongs to the technical field of transportation trolleys, and aims to solve the problems that when goods are transported by a traditional railway, rails in a station are staggered, a common transportation trolley cannot directly shuttle on the surfaces of the rails, workers need to stride over the rails for carrying, and time and labor are wasted. The supporting wheels are mounted at the bottom of the main body device; the bottom of the steering transportation mechanism is rotationally connected with the main body device; the supporting device is mounted at the bottom of the main body device; the supporting device in the device can provide an auxiliary supporting effect for the whole device and prevent the device from turning on one side, goods can be controlled to be transported in a steering mode through the motor, time and labor are saved, and the goods carrying effect can be effectively improved; and when the goods
