Transverse moving carrying trolley positioning device for full-automatic prefabricated segment production line

The utility model discloses a transverse moving carrying trolley positioning device for a prefabricated segment full-automatic production line. The transverse moving carrying trolley positioning device comprises a supporting piece and an elastic buffering piece. The supporting piece is arranged at the upper end of the elastic buffering piece, and a semicircular groove is formed in the supporting piece in the front-back direction. The right side of the groove is provided with an inclined surface, and the right end of the inclined surface is lower than the lower side of the wheel axle; when the wheel axle moves in the direction close to the supporting piece in the horizontal direction, the wheel axle forces the supporting piece to press the elastic buffering piece downwards through the inclined face till the wheel axle makes contact with the stop face, the elastic buffering piece forces the supporting piece to reset upwards, and therefore the wheel axle is located in the groove. When the wheel axle moves in the
