Excavator and control device for excavator

Abstract

An excavator includes a lower traveling body; an upper turning body turnably mounted on the lower traveling body; and a control device including circuitry, the circuitry being configured to perform notification of whether or not the upper turning body directly faces a target construction surface based on information about the target construction surface and information about an orientation of the upper turning body.

What is claimed is: 
     
         1 . An excavator comprising:
 a lower traveling body;   an upper turning body turnably mounted on the lower traveling body; and   a control device including circuitry, the circuitry configured to perform notification of whether or not the upper turning body directly faces a target construction surface based on information about the target construction surface and information about an orientation of the upper turning body.   
     
     
         2 . The excavator according to  claim 1 , wherein the circuitry performs the notification when a first switch is operated. 
     
     
         3 . The excavator according to  claim 1 , wherein the circuitry is configured to execute directly-facing control for causing the upper turning body to turn so that the upper turning body directly faces the target construction surface, based on the information about the target construction surface and the information about the orientation of the upper turning body, and to perform notification that the directly-facing control is being executed in a case where the directly-facing control is being executed. 
     
     
         4 . The excavator according to  claim 3 , wherein the circuitry is configured to perform notification of completion of the directly-facing control in a case where the upper turning body directly faces the target construction surface due to execution of the directly-facing control. 
     
     
         5 . The excavator according to  claim 4 , wherein the circuitry is configured to perform notification of a case where the upper turning body directly faces the target construction surface, a case where the upper turning body does not directly face the target construction surface, a case where the directly-facing control is being executed, and a case where the directly-facing control is completed, in a mutually distinguishable manner. 
     
     
         6 . The excavator according to  claim 3 , wherein the circuitry is configured to execute the directly-facing control in a case where an operation of turning the upper turning body is performed while a second switch is operated. 
     
     
         7 . The excavator according to  claim 1 , further comprising:
 an attachment attached to the upper turning body; and   an operation device configured to operate the attachment,   wherein when an operation is performed on the operation device in a state where a third switch is operated, the circuitry operates the attachment based on the operation performed on the operation device, information acquired about a position and an orientation of the excavator, and information registered in advance.   
     
     
         8 . The excavator according to  claim 1 , wherein the circuitry performs the notification by sound or display. 
     
     
         9 . A control device for an excavator, the excavator including a lower traveling body, and an upper turning body turnably mounted on the lower traveling body, the control device comprising:
 circuitry configured to perform notification of whether or not the upper turning body directly faces a target construction surface, based on information about the target construction surface and information about the orientation of the upper turning body.   
     
     
         10 . The excavator according to  claim 1 , further comprising:
 an attachment attached to the upper turning body; and   an operation device configured to operate the attachment,   wherein the circuitry is configured to
 execute directly-facing control for causing the upper turning body to turn so that the upper turning body directly faces the target construction surface, based on the information about the target construction surface and the information about the orientation of the upper turning body, 
 perform the notification in a case where a first switch is operated, 
 execute the directly-facing control in a case where an operation of turning the upper turning body is performed while a second switch is operated, and 
 when an operation is performed on the operation device in a state where a third switch is operated, activate the attachment based on the operation performed on the operation device, information acquired about a position and an orientation of the excavator, and information registered in advance, and 
   wherein the first switch, the second switch, and the third switch are the same switch.
