Abstract: At present, there was no systematic method for the structural innovation design of large mining shovel, and there was no relevant report on the configuration synthesis of mining shovel. Aiming at the problem, the constraint synthesis method based on screw theory was used to study the configuration synthesis of large mining shovel.First of all, according to the screw theory, the degree of freedom of the pushing and lifting mechanism model of the mining shovel was analyzed and calculated, and the comprehensive desired motion of the electric shovel configuration was obtained. Secondly, using the constraint synthesis method based on screw theory, two configuration schemes were used to synthesize the configuration of the mining shovel, and through the optimization and screening of the branched chain structure, 100 three-chain electric shovel configuration I and 14 two-branch electric shovel configuration Ⅱ were obtained. Finally, the three-dimensional model was established by the modeling software SolidWorks, and ADAMS software was used to simulate and analyze the excavation trajectory of the simplified model of large mining shovel and a new synthesized configuration. The research results show that the motion simulation trajectory of the new configuration of the electric shovel is basically consistent with the theoretical excavation trajectory, which verifies the feasibility of the configuration method and provides more optional configurations for the structural innovation design of diversified mining electric shovels.
