Beam body support transverse moving device and method

The invention discloses a device and method for supporting and transversely moving a beam body, and the device comprises a track which is laid on the upper surface of a cover beam; the two movable vehicle bodies are installed on the same track and can move along the track, and the two movable vehicle bodies are connected in a spaced mode to achieve synchronous movement; the two telescopic inclined supporting rods are arranged corresponding to the moving vehicle bodies, the bottom ends of the telescopic inclined supporting rods are hinged to the corresponding moving vehicle bodies, and the upper ends of the telescopic inclined supporting rods can stretch out and draw back to achieve inclined supporting on the two sides of the beam body; and the transverse moving driving piece is arranged on the upper surface of the cover beam and used for supporting the beam body and driving the beam body to move in the direction parallel to the track. Movement guiding of the beam body is achieved through cooperation of the ra
