CONCRETE PUMP TRUCK AND VIBRATION REDUCTION APPARATUS AND METHOD FOR CONCRETE PUMP TRUCK-MOUNTED BOOM

摘要

The present invention discloses a concrete pump truck and an apparatus and a method for reducing the vibration of a boom of the concrete pump truck. The apparatus for reducing the vibration of the boom of the concrete pump truck comprises: a vibration reduction control unit (11), which is connected with an electromagnetic proportional valve (12) connected with boom cylinder (2), a boom terminal vibration monitoring unit (21), which is used for monitoring a amplitude parameter of the tail boom section (14) of the boom (13) and transmitting an amplitude parameter signal to the vibration reduction control unit (11), and a boom posture monitoring unit (20) which is used for monitoring an angle parameter of the boom (13) and transmitting an angle parameter signal to the vibration reduction control unit (11). The concrete pump truck of the present invention further comprises the apparatus for reducing the vibration of the boom of the concrete pump truck. The method for reducing the vibration of the boom of the concrete pump truck provided by the present invention comprises the following steps: monitoring the operating parameters of a concrete pump and the boom (13); generating a control signal according to the monitored operating parameters, outputting an control current of an electromagnetic proportional valve (12) according to the control signal, and controlling the piston positions of the boom cylinder (2); wherein the monitored operating parameters of the boom (13) comprise a vibration amplitude parameter of the tail boom section (14) and an angle parameter of the boom (13).
