Integral counterweight assembly of dynamic compactor

Abstract

The invention discloses an integral counterweight assembly of a dynamic compactor. The integral counterweight assembly comprises a bottom counterweight, at least two upper counterweights and a counterweight limiting seat, the bottom counterweight is provided with a stud for fixed installation, the upper surface of each upper counterweight is provided with a positioning pin, the lower surface of each upper counterweight is provided with a positioning hole matched with the corresponding positioning pin in an inserted manner, so that the upper counterweights are stacked in sequence, a connecting lug plate fixed to the counterweight limiting seat through a plug pin is arranged on the side edge of the bottom counterweight, and the counterweight limiting seat is used for being fixedly installed on a dynamic compactor platform. By means of the connecting mode of the bottom counterweight and the upper counterweights, the upper counterweights, the bottom counterweight and the dynamic compactor counterweight platform, the bottom counterweight is in threaded connection with the detachable positioning pin while the machining precision is guaranteed, under the long-term impact load, the positioning pin can be replaced after deformation, and the upper counterweights are more convenient and efficient to install.

Description

technical field [0001] The invention relates to the technical field of heavy industry machinery, in particular to an integral counterweight assembly of a dynamic compaction machine. Background technique [0002] In the field of dynamic tamping machine engineering machinery, the existing counterweights are mostly mixed small units made of concrete and iron blocks, and multiple counterweights are combined by welding positioning pins to form a counterweight assembly. [0003] The existing counterweight adopts the positioning method of "two holes on one side", which is based on the combined positioning of the plane and the inner hole. On large-scale counterweights, welding positioning pins are often used to ensure installation accuracy; while the counterweight assembly Overall stability relies on threaded connections for fastening. [0004] In the field of dynamic compaction, the whole machine has to withstand high-frequency repeated impact dynamic loads, and the installation s...
