Embodiment Construction

[0047] refer to figure 1 , which shows an extendable articulated arm 11 capable of dispensing concrete or similar material for the construction industry and positioned in a position mounted on a heavy work vehicle 12 in a folded condition for transport and containing control means 10, to control and dampen the vibration that the articulated arm 11 receives during the working state.

[0048] The articulated arm 11 is set to come from figure 1 transition from the folded state shown to the extended or working state, an example of the latter is at figure 2 shown in .

[0049] The heavy work vehicle 12 includes a cab 13 and a support frame 14 on which the articulated arm 11 is mounted.

[0050] The articulated arm 11 comprises a plurality of joint segments, for example, in the shown scheme, comprises six segments, respectively the first segment 15, the second segment 16, the third segment 17, the fourth segment 18, The fifth segment 19 and the sixth segment 20, which are pivot...

Abstract

Apparatus to actively control the vibrations of an articulated arm(11), for example for pumping concrete, consisting of a plurality of segments(15-20) pivoted to each other in correspondence to their own pivoting ends(23) and of drive actuators(24) each cooperating with two of said segments in order to extend and/or fold back the articulated arm. Each of the drive actuators(24) is connected to a drive circuit in order to act on a vertical plane substantially defined by the two segments of the articulated arm to which it is associated. Said apparatus also comprises at least one auxiliary actuator associated to at least one of said segments of the articulated arm in proximity to at least one of the pivoting ends(23), said auxiliary actuator being provided with at least two operative ends, each of said operative ends being connected to a corresponding support, said supports being provided on said segment distanced to each other along the longitudinal development of said corresponding segment and defining, on the segment(15-20), respective application zones, said auxiliary actuator(28) being selectively activable to induce, in said application zones, compensation forces acting on a damping plane which is different from said vertical plane.

Description

technical field [0001] The present invention relates to a device and a corresponding method for controlling the vibrations of an articulated arm, especially (but not only) for pumping concrete and associated with a transport vehicle in so-called on-board pumps. [0002] More particularly, the present invention relates to a device for active control used to reduce vibrations to which segments of an articulated arm are used for pumping concrete in operating machines such as vehicle-mounted A pump, concrete mixer truck or something like that. In EP-A-2347988 a device for controlling the vibration of an articulated arm for pumping concrete is disclosed. Background technique [0003] Heavy work vehicles are known to be used in the construction industry and generally consist of trucks on which articulated arms are mounted for dispensing and pouring concrete. These trucks are available with or without concrete mixers. [0004] A known type of extendable articulated arm consists ...
