Abstract

The invention relates to a lifting mechanism and belongs to the field of engineering equipment, in particular to a mining excavator lifting mechanism. The mining excavator lifting mechanism comprises a primary speed reduction drive mechanism, a secondary speed reduction drive mechanism and a motor, the non-load end of the motor is provided with a brake, and the load end is connected with the primary speed reduction drive mechanism through a coupling. Because the mining excavator lifting mechanism uses a single-motor single-winding drum structure and two hoisting ropes, the diameter of each hoisting rope is small, the diameter of the lifting winding drum is small, the drive ratio is reduced, the whole mechanism is simple in structure, light in weight, small in volume, less in drive piece number and small in processing and assembly workload, and the manufacturing cost is greatly lowered.

Description

technical field [0001] The invention relates to a lifting mechanism, belonging to the field of engineering equipment, in particular to a lifting mechanism for a mining excavator. Background technique [0002] Energy saving and emission reduction and green manufacturing are the mainstream of the equipment manufacturing industry. Structural optimization and equipment weight reduction are undoubtedly a very important branch of this mainstream. As an important equipment in the energy field, mining excavators should contribute to the weight reduction of structural optimization equipment. The lifting mechanism of the mining excavator 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 both in volume and weight. very objective. The main part of the lifting mechanism is in the machine roo...
