A gantry device and control method; the gantry device comprises a support device, a gantry frame body (8) provided on the support device via a gantry frame connecting device, a sensing unit (2, 5) and a scanning galvanometer (4) arranged on the gantry frame body (8), a sensing unit (3) arranged on the support device, and a vertical actuator (6) located between the scanning galvanometer (4) and the gantry frame body (8) and used to support the scanning galvanometer (4) to move vertically; the gantry frame body (8) cooperates with the gantry frame connecting device to realize the horizontal movement and vertical movement of the gantry frame body (8); according to measurement values of the sensing units (2, 3, 5), a vertical setting value of the sensing unit (5) for measuring the height of the scanning galvanometer (4) is acquired, and then the scanning galvanometer (4) is moved so as to adjust the optimal focal point of the scanning galvanometer (4) to a target point. |
