Embodiment 1

[0019] The present invention is a method for controlling an excavator, wherein the excavator includes a controller, a left pedal and a right pedal; the method for controlling an excavator comprises the following steps: detecting the acceleration in three axis directions of the controller through a three-axis acceleration sensor, And detect the state of the left and right pedals; get the displacement of the controller in the three axes according to the acceleration in the three axes of the controller; control the movement of the bucket, arm and boom according to the displacement in the three axes of the controller; Control the movement of the upper body of the excavator according to the state of the left and right pedals.

[0020] During the implementation of this embodiment, the operation of the excavator is controlled by the controller, the left pedal and the right pedal, as follows: first, the acceleration in the three axis directions of the controller is detected by the thre...

Embodiment 2

[0022] In this embodiment, on the basis of Embodiment 1, the control of the movement of the upper body of the excavator according to the state of the left pedal and the right pedal includes the following sub-steps: when the left pedal is stepped down and the right pedal is not stepped down, the upper body rotates to the left turn; when the left pedal is not stepped down and the right pedal is stepped down, the upper car body rotates to the right; when the left pedal is stepped down and the right pedal is stepped down, the upper car body does not rotate; The body does not rotate.

[0023] When this embodiment is implemented, the rotation of the upper part of the excavator is operated through the left pedal and the right pedal, which is not easy to cause work fatigue and reduces the risk of accidents.

Embodiment 3

[0025] In this embodiment, on the basis of Embodiment 1, the three axis directions include the first direction, the second direction and the third direction; the bucket, arm and boom are controlled according to the displacement of the controller in the three axis directions The movement of the method includes the following sub-steps: controlling the movement of the bucket according to the displacement in the first direction; controlling the movement of the arm according to the displacement in the second direction; controlling the movement of the boom according to the displacement in the third direction.

[0026] When this embodiment is implemented, the first direction is defined as the vertical direction, that is, up and down; the second direction is defined as the horizontal direction, that is, left and right; the third direction is defined as the horizontal and vertical direction, that is, front and rear; according to the first direction The displacement controls the movement...

Abstract

The invention discloses a control method of an excavator. The excavator comprises a controller, a left pedal and a right pedal; the control method of the excavator comprises the following steps: detecting the accelerated speeds of the controller in three axial directions through a three-axis acceleration sensor, and detecting the states of the left pedal and the right pedal; acquiring the displacements of the controller in the three axial directions according to the accelerated speeds of the controller in the three axial directions; controlling the motions of a bucket, a bucket rod and a moving arm according to the displacements of the controller in the three axial directions; and controlling the motion of the upper vehicle body of the excavator according to the states of the left pedal and the right pedal. According to the control method of the excavator, the bucket, the bucket rod and the moving arm are controlled through the sensor, the phenomenon that the operating arm is difficult to operate due to reasons such as aging, oil hole blockage and the like of a hydraulic device after long-time usage is avoided, and the rotation of the upper vehicle body of the excavator is controlled through the left pedal and the right pedal; besides, when an operator takes the sitting posture, the foot force is far greater than the hand force, so that the operator is not liable to work fatigue, and the risk of accident occurrence is reduced.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an excavator control method. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to excavate materials that are higher than or lower than the bearing surface, and load them into a transport vehicle or unload them to a stockyard. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. [0003] However, when the excavator is in working condition, the operating lever often becomes difficult to operate due to reasons such as the oil hole of the hydraulic cylinder is not smooth. occur. Contents of the invention [0004] The technical problem to be solved by the present i...
