Problems solved by technology

However, when the turntable of the excavator is rotated to 180°, the driver is working backwards. At this time, if the operating lever or the pedal is in the forward state, the excavator walks backward relative to the driver; if the operating lever or the pedal is in the backward state, The excavator walks forward relative to the driver, which increases the difficulty of the driver's operation

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] figure 1 It is a structural diagram of the excavator walking control device provided by the present invention. The walking control device of the excavator includes: an angle judging device 1, which is used to judge the range of the rotation angle of the turntable and outputs the judgment result; a sensor 2, which is used to sense the state of the operating lever or the pedal; and a controller 3, which is connected with the The angle judging device 1 is connected to the sensor 2 for receiving the judging result and the state of the joystick or the pedal, and when the angle judging device 1 judges that the rotation angle is greater than -90° and less than In the range of 90°, if the operating lever or the pedal is in the forward state, the controller 3 controls the driving system of the excavator to drive the excavator forward; if the operating lever or the pedal...

Abstract

The invention provides a travelling control device for an excavator, which comprises an angle determining device, a sensor and a controller, wherein the angle determining device is used for determining the range of the rotation angle of a rotating table and outputting the result of the determination; the sensor is used for sensing the state of an operating rod or pedal; and the controller is connected with the angle determining device and the sensor and is used for receiving the result of the determination and the state of the operating rod or pedal and, according to the range of the rotationangle and the state of the operating rod or pedal, controlling the driving system of the excavator to drive the excavator to move forward and backward. The travelling control device for the excavator, which is provided by the invention, can make the direction of the operating rod or pedal forward and backward movement control action of a driver consistent with the direction of the movement of theexcavator relative to the driver, thereby improving operating comfort.

Description

technical field [0001] The invention relates to an excavator travel control device and method. Background technique [0002] The travel of traditional excavators adopts a hydraulic control method, that is, the driver controls the hydraulic valve through the operating lever or the pedal, thereby controlling the pilot oil circuit to push the main spool to move, so that the working oil pressure of the main oil circuit leads to the travel motor, driving the travel motor to work . Since this control method is full hydraulic control, when the driver operates facing forward, if the operating lever or pedal is in the forward state, the excavator will move forward; if the operating lever or pedal is in the backward state, the excavator will move backward. However, when the turntable of the excavator is rotated to 180°, the driver is working backwards. At this time, if the operating lever or the pedal is in the forward state, the excavator walks backward relative to the driver; if th...
