Provided is an automatic locating perpendicular steering rail transfer steel mold trolley. Travelling wheel sets capable of rotating along a perpendicular rotary shaft are arranged at the bottom of the steel mold trolley. A transverse rail and a longitudinal rail are arranged in the shape like a Chinese character ''jing''. The staggered position of the transverse rail and the longitudinal rail is provided with a rotary rail device. The number of the travelling wheel sets is four. The transverse space and between the travelling wheel sets corresponds to the longitudinal rail. The longitudinal space and between the travelling wheel sets corresponds to the transverse rail. In the rotary rail device, a rotary rail is fixedly installed on a rotary rail disk which is rotationally connected with a rotary rail embedded part through a rotary rail rotary shaft at the bottom. According to the automatic locating perpendicular steering rail transfer steel mold trolley provided by the invention, the staggered rails are arranged, and the staggered position is provided with the rotary rail device capable of rotating, so that perpendicular steering rail transfer is achieved conveniently, the safety is high, and derailing does not occur. A locating emitter and a locating receiver are arranged and matched with a jacking device so that a steering position can be located accurately, and reliable rail transfer steering is achieved.
