Abstract

The invention discloses a lifting mechanism of an electric shovel, which comprises a drum inner sleeve, a transmission side spindle, a first grade sun wheel, a first grade planet wheel pin shaft, a first grade planet wheel, a first grade inner gear ring, a first grade planet carrier, a second grade planet carrier, a second grade planet wheel pin shaft, a second grade inner gear ring, a second grade planet wheel, a second grade sun wheel support, a second grade sun wheel and a fixation side spindle, wherein a first grade speed-reduction transmission mechanism comprises the first sun wheel, the first grade planet wheel, the first grade inner gear ring and the first grade planet carrier; and a second grade speed-reduction transmission mechanism comprises the second grade sun wheel, the second grade planet wheel, the second grade inner gear ring, the second grade planet carrier and the second grade sun wheel support. According to the invention, as the single-motor input is adopted, and the two grades of the speed-reduction transmission mechanisms are installed in the drum inner cavity, the space in the drum is completely utilized; the speed-reduction mechanisms adopt two grades of planet gear wheels to realize transmission, so that the transmission of the planet gear wheel has great transmission ratio; and the lifting mechanism is compact in structure and can greatly reduce the weight of the equipment.

Description

technical field [0001] The invention relates to mining equipment, in particular to an electric shovel lifting mechanism. Background technique [0002] Energy saving, emission reduction, and green manufacturing are the mainstream of the development of the equipment manufacturing industry, and structural optimization and equipment weight reduction are undoubtedly a very important branch of this mainstream. As an important equipment in the energy field, the electric shovel should contribute to the weight reduction of structural optimization equipment. As the lifting mechanism in the working device of the electric shovel, it plays a role in overcoming the tangential excavation resistance during the excavation process. Such working conditions require the lifting mechanism to require high power and high mechanical structural strength. Therefore, the lifting mechanism is in terms of volume and weight. It's all very objective. The main part of the hoisting mechanism is in the cabi...
