Document Type and Number:
Japanese Patent JP2021046291
Kind Code:
A
Abstract:
To provide a vibration suppression device for a measurement device, which can direct the measurement device within a prescribed range based on a target attitude angle as a reference even when vibration is applied.SOLUTION: A vibration suppression device 30 of a suspended load camera 9b comprises: the suspended load camera 9b supported by a boom 9 so as to swing; a motor 33 for swinging the suspended load camera 9b; and a vibration control unit 36 that controls the motor 33. The vibration control unit 36 stores, in advance, information about vibration of the boom 9 when a crane device 6 is optionally operated with the weight of an optional load W and an optional attitude, estimates, upon acquisition of the attitude information of the crane device 6, the weight of the load W, and an operation signal of the crane device 6, the vibration of the boom 9 from the attitude information and the operation signal on the basis of the vibration information, calculates an estimated disturbance torque d applied to the suspended load camera 9b through the estimated vibration of the boom 9, and controls the motor 33 so as to cancel the calculated estimated disturbance torque d.SELECTED DRAWING: Figure 5
