The invention discloses an arm frame device of a dynamic compaction machine, which comprises an upper section arm frame, a lower section arm frame, an intermediate arm frame and an arm frame head. A cladding plate is externally connected to the joint between the intermediate arm frame and an anti-roll bar, and the cladding plate and All the main chords of the intermediate jib are connected, and the cladding plate is provided with a connecting part connected with the anti-roll bar. In the present invention, a cladding plate is externally connected to the joint between the intermediate jib and the anti-roll bar, and the cladding plate is connected with all the main chords of the intermediate jib to wrap all the main chords to form a box-shaped beam structure. One end of the anti-roll bar is connected to the cladding plate, and the cladding plate will transmit the reaction force of the anti-roll bar to each main chord. There are more main chords to bear the reaction force of the anti-roll bar, and each main chord bears The reaction force will become smaller, and the main chord will not be easily twisted and deformed. The arm support device of the dynamic tamping machine in the present invention can prevent the twisting and deformation of the main chord, thereby ensuring the normal operation of the dynamic tamping machine. The invention also discloses a dynamic compactor provided with the above-mentioned dynamic compactor arm support device.
Description
technical field [0001] The invention relates to the field of large machinery, and more specifically, relates to an arm support device of a dynamic compactor and a dynamic compactor. Background technique [0002] The anti-roll bars of the dynamic compaction machine usually include two, one end of the two anti-roll bars is connected on the A-frame, and the other end is respectively connected on the two main chords. After the dynamic tamping machine releases the heavy hammer, the boom will have a tendency to tilt backward instantly, and at this time, the anti-roll bar will give the boom a reaction force to prevent the boom from tilting backward. Since the two anti-roll bars are only connected to the two main chords, the reaction force of the anti-roll bars only acts on the two main chords. In the case of a large reaction force, the two main chords connecting the anti-roll bar are likely to be twisted and deformed, which will affect the normal operation of the dynamic compactio...
