The invention provides a gravity center adjusting method of engineering machinery and the engineering machinery. The gravity center adjusting method of the engineering machinery comprises the following steps: S1, obtaining a first torque applied by a working device of the engineering machinery relative to the engineering machinery; and S2, adjusting rotation of an eccentric balance weight of the engineering machinery according to the first torque, so as to balance second torque and the first torque applied to the engineering machinery by the eccentric balance weight. According to the technical scheme, the defects that in the prior art, an excavator is poor in stability and prone to shaking when working due to the fact that a balance weight of the excavator cannot adjust torque changes of a working arm in the working process are overcome.
Description
technical field [0001] The invention relates to the technical field of construction machinery leveling devices, in particular to a method for adjusting the center of gravity of construction machinery and construction machinery. Background technique [0002] Excavators are commonly used construction machinery. The excavator in the prior art is fixedly provided with a counterweight at the rear, and the counterweight can balance the torque generated when the bucket is excavated, thereby preventing the excavator from overturning. Further, in order to ensure the working safety of the excavator on inclined road conditions, some excavators in the prior art drive the counterweight to move through the driving structure. When it is detected that the excavator is on an inclined road condition, the driving structure adjusts the position of the counterweight, thereby Adjust the position of the center of gravity of the excavator to ensure the safety of the excavator when working on incli...
