[0003] The general steel truss boom is composed of a base boom, a middle boom and a top boom. The existing middle boom includes four chords that The webs between the rods, the top jib and the base jib are quadrangular platform-shaped structures welded by four chords and webs. Before assembly, the base jib, middle jib and The top boom is formed by pairing. The basic boom, middle boom and top boom are generally paired manually. After the pairing is completed, the three sections are manually connected into an overall structure. In the specific installation process, manual pairing is basically used at present. In this way, there are disadvantages such as out-of-tolerance boom straightness, out-of-tolerance overall assembly diagonal, incorrect angle, assembly deviation, non-interchangeability, low production efficiency, and high skill requirements for workers during production. When the pairing of the connectors is seriously affected, it will lead to scrapping and waste of raw materials

The invention discloses a dynamic compactor moving arm combination tool. The dynamic compactor moving arm combination tool comprises a base arm frame assembly tool, a middle arm frame assembly tool, a top arm frame assembly tool and a butt joint tool, wherein the base arm frame assembly tool, the middle arm frame assembly tool and the top arm frame assembly tool are respectively used for assembling a base arm frame, a middle arm frame and a top arm frame; the butt joint tool is used for connecting the base arm frame, the middle arm frame and the top arm frame which are assembled; and as the tools matched with the base arm frame, the middle arm frame and the top arm frame are used for assembling, a tool matched with the structural shape of a moving arm is used as a positioning mechanism to respectively position the top arm frame, the middle arm frame and the top arm frame which are assembled, and the connected ends are welded as an integrated structure, the assembly welding precision is improved, the operation efficiency is improved, the interchangeability is higher, and the product scrapping and the material waste are prevented.
Description
technical field [0001] The invention relates to the technical field of dynamic ramming machine arm assembly, in particular to a dynamic ramming machine arm assembly tooling. Background technique [0002] With the development of large-scale and gigantic industrial projects, in terms of equipment manufacturing and engineering installation, the requirements for the allowable lifting quality of cranes are gradually increasing. Cranes or dynamic compactors use the boom as a supporting structure. However, with the lifting quality With the improvement of boom strength, the requirements for the strength of the boom are getting higher and higher, and the weight of the boom itself is also gradually increasing, which limits the improvement of the lifting quality of cranes or dynamic compaction machines to a certain extent. For this reason, some large-scale cranes and dynamic compaction machines Both began to adopt the steel truss boom structure. On the one hand, the quality of the stee...
