CONCRETE-PLACING EQUIPMENT, AND VIBRATION SUPPRESSION METHOD, CONTROLLER AND DEVICE FOR BOOM THEREOF

摘要

The present invention discloses a boom vibration suppression method for concrete distributing apparatus, wherein, the boom comprises a boom oil cylinder (1) for respectively driving each section of the boom; the vibration suppression method comprises: detecting the variation of output force of the boom oil cylinder (1), and maintaining the variation of output force within the range of a preset threshold. The present invention further provides a vibration suppression controller, a vibration suppression device, and a concrete distributing apparatus that implement the method described above. In the present invention, since the variation of output force of the boom oil cylinder is detected to reflect the vibrations on the boom, without the need for detecting the posture and end displacement of the boom, the vibration of the boom is controlled directly and the time delay is little delay; moreover, the pressure of the boom oil cylinder is controlled directly and the variation of output force is maintained within a specific range; that control process is applicable to any boom posture since it has no direct relationship with the posture and dynamic characteristics of the boom; furthermore, the device that implements the method disclosed in the present invention is simple in structure and is high portability without any modification to the original system.
