Abstract

The invention relates to an excavator which comprises a frame assembly, a motor, an operation mechanism, a swing mechanism, a walking mechanism and a transmission mechanism. The frame assembly comprises an upper frame and a lower frame, a motor and an operation mechanism are arranged on the upper frame, a walking mechanism and a transmission mechanism are arranged on the lower frame, the upper frame and the lower frame are connected through a swing mechanism, the swing mechanism is connected with the output end of the motor, and the swing mechanism is used for driving the upper frame to rotate relative to the lower frame; the transmission mechanism is connected with the output end of the motor, the transmission mechanism is in transmission connection with the walking mechanism, the transmission mechanism is used for conveying power of the motor to the walking mechanism, and the walking mechanism is used for driving the excavator to walk forwards or backwards. According to the technical scheme, the functions of advancing and retreating of the whole machine and free rotation of the frame can be achieved through driving action of one motor, and compared with the mode that a hydraulic oil pump supplies oil to a hydraulic motor for driving, the efficiency of the motor is high, and energy consumption is greatly reduced.

Description

technical field [0001] The present application relates to the field of excavators, in particular to an excavator. Background technique [0002] The upper frame and the lower frame of the excavator are connected by a slewing bearing. In a traditional fuel excavator, the rotation of the upper frame is realized by the hydraulic motor installed on the upper frame driving the gear meshing with the rotary gear ring, so as to achieve the digging effect. Bucket index excavation and unloading functions. However, every time excavation and unloading is completed, one rotation is required, and at the same time, the working face leveling process when the bucket swings also needs to be rotated on the frame. In the process of energy consumption of the whole machine, the energy consumed by the rotation is estimated to occupy the working process of the whole machine. 20%-30% of the energy consumption; the hydraulic pump provides the power oil for the hydraulic motor, and the work of the hyd...
