Abstract

The invention provides a concrete pump truck, a damping device and a damping method for a concrete pump trunk arm support. The damping device of the concrete pump trunk arm support comprises a damping control unit, an arm support tail end vibration monitoring unit and an arm support posture monitoring unit, wherein the damping control unit is connected with an electromagnetic proportional value connected with an arm support cylinder; the arm support tail end vibration monitoring unit monitors amplitude parameters of a tail arm of the arm support and transmits amplitude parameter signals to the damping control unit; and the arm support posture monitoring unit monitors angle parameters of the arm support and transmits angle parameter signals to the damping control unit. The concrete pump truck also comprises the damping device of the concrete pump truck arm support. The damping method for the concrete pump truck arm support comprises the following steps of: monitoring operation parameters of a concrete pump and the arm support; generating control signals according to monitoring parameters; and outputting an electromagnetic proportional valve control current according to the control signals to control a piston position of the arm support cylinder, wherein the monitoring parameters of the arm support comprise the vibration amplitude parameters of the tail arm of the arm support and the angle parameters of the arm support.

Description

Technical field [0001] The present invention relates to the field of construction engineering machinery, and specifically to a concrete pump truck and a vibration reduction device and method for a concrete pump truck boom. Background technique [0002] At present, large-scale equipment equipped with multi-section rotating arms is widely used in construction projects for concrete construction, such as concrete pump trucks installed on truck chassis. Its main function is to transport concrete from the location of the pump truck to the designated location of the construction project. target location. [0003] A concrete pump truck mainly includes a chassis, concrete pump, pipes and boom. The concrete is alternately pushed into the concrete delivery pipe by the dual supply cylinders installed on the chassis of the pump truck through the connecting mechanism. The pipe is fixed on the side of the boom and moves together with the rotating boom, so that the concrete can be transpor...
