Steering device of plant factory inspection robot

The utility model discloses a plant factory inspection robot steering device which comprises a steering wheel, a steering column, an input shaft, an output shaft, a torsion bar, a universal joint A, a main connecting rod, an auxiliary connecting rod, a universal joint B and a rack, the top end of the steering column is connected with the steering wheel, and a rotating mechanism is arranged between the rack and the universal joint B. According to the steering device, the steering motor is modified on the steering wheel, the steering shaft is controlled to rotate through the steering motor, the steering shaft drives the input shaft and the output shaft to rotate, and therefore the function of rotation transmission is achieved, and the electric power steering mechanism is arranged on the output shaft and composed of the motor and the worm and gear transmission device. The electric power steering mechanism can greatly reduce the torque required during direction rotation, so that the direction control is more accu
