Abstract

The invention relates to a dynamic compactor boom and a dynamic compactor. The dynamic compactor boom comprises a bottom knuckle arm, a plurality of middle knuckle arms and a top knuckle arm, wherein the bottom knuckle arm, the middle knuckle arms and the top knuckle arm are sequentially connected in series and are respectively knuckle arms with a trussed structure mainly composed of an upper main chord member, a lower main chord member, a diagonal web member and a transverse connecting rod, and the knuckle arms are connected with each other through pin shafts; the cross section area of the dynamic compactor boom is homogeneously and linearly increased from the top knuckle arm to the bottom knuckle arm. The vibration and fatigue problems of large-energy-level dynamic compactors of the prior art can be improved, and meanwhile the processing technology and the disassembly and assembly problem of the boom can be considered.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a dynamic compaction machine arm frame and a dynamic compaction machine provided with the dynamic compaction machine arm frame. Background technique [0002] With the acceleration of urbanization in our country, a large number of land reclamation and land reclamation projects have been carried out, and the collapsible loess area and soft clay area are widely distributed in our country, so the dynamic compaction construction machinery will develop into large-scale and serialized . The arm frame is the key operating part of the dynamic compaction machine, and the rammer is lifted and unloaded by the arm frame to realize the compaction of the foundation. The booms of existing crawler-type dynamic compaction machines are mostly born out of the booms of crawler cranes. With the development of the dynamic tamping machine, a series of problems such as boom design, production, inst...
