Abstract
The utility model discloses an anti-collision bracket for an arm support of a dynamic compaction machine. The anti-collision bracket comprises a bracket solder (81), an elastic buffer device (82), a positioning device (83) and a movable frame (84). The anti-collision bracket is arranged on one side of each of arm support main chord members (10), which faces a lifting hook (3); and one end of the bracket solder (81) is connected with the movable frame (84) in a sliding mode by the elastic buffer device (82) and is limited by the positioning device (83). When the anti-collision bracket is impacted, the movable frame (84) in the anti-collision bracket compresses the elastic buffer device (82), the elastic buffer device (82) relieves impact energy and transfers the residual impact energy to the arm support main chord members (10), and the lifting hook cannot move to a web member due to blocking of the anti-collision bracket, so that the phenomenon that the web member is impacted to be bent is avoided.
