This invention discloses a double-layer
fully automatic opening and closing roller beam device for subway
rail transportation, including an upper roller beam, a lower roller beam, a drive column, and side columns corresponding to the drive column. The horizontally transverse upper roller beam is rotatably mounted on the drive column at one end and rests on the side column at the other end. It also includes an
automatic control mechanism and a roller beam rotation support mechanism on the same longitudinal line as the drive column. The
automatic control mechanism includes a control host and several position sensors installed on the side columns and the roller beam rotation support mechanism to transmit the position information of the upper roller beam. The position sensors feed back signals to the control host to automatically control the opening and closing of the upper roller beam. It is installed on an adjustable height support beam, which includes a support beam, crossbeam support feet, and a crossbeam height adjustment mechanism. It has the advantages of
fully automatic opening and closing of the roller beam, simple operation, time and labor saving, high personal safety factor, and high overall
structural stability.
