Abstract

According to the present invention, a display system of a turning work vehicle is used for the turning work vehicle in which a work machine having a bucket 8 can be offset relative to a revolving superstructure in the horizontal direction. The display system includes: an arithmetic unit that calculates the position of the bucket on the basis of a detection result obtained by a position detecting device provided on the turning work vehicle, and calculates a necessary revolving amount of the revolving superstructure and a necessary offset amount of the work machine that are needed to align a side section of the bucket with a side edge of a predetermined excavation area; and a display device that displays the positional relationship between the bucket and the predetermined excavation area.

Claims (23)

1. A display system of a turning work vehicle, the display system being used for the turning work vehicle which can offset a work machine including a bucket relative to a revolving superstructure in a horizontal direction, the display system comprising:

an arithmetic unit, which calculates a position of the bucket based on a result of detection by a position detecting device installed on the turning work vehicle, and calculates a necessary revolving amount of the revolving superstructure and a necessary offset amount of the work machine that are needed to align the bucket with a predetermined excavation area; and

a display device which displays on a single screen

information for informing about a revolving angle of the revolving superstructure according to the necessary revolving amount, and

information for informing about a swing angle of the work machine according to the necessary offset amount,

wherein a second display field shows a second position and posture of the turning work vehicle at a second state, and the second display field displays the revolving superstructure and the work machine detached from each other on the single screen.

2. The display system of the turning work vehicle according to claim 1 , wherein the offset of the work machine is performed by swinging the work machine right and left with respect to the revolving superstructure.

3. A turning work vehicle comprising: the display system of the turning work vehicle according to claim 1 ; a lower traveling body; the revolving superstructure which is provided above the lower traveling body so as to be revolvable; and the work machine which can be offset relative to the revolving superstructure in a horizontal direction.

4. The display system of the turning work vehicle according to claim 1 , wherein the display device displays a positional relationship between the bucket and qathe predetermined excavation area, and a side section of the bucket is aligned with a side edge of the predetermined excavation area.

5. The display system of the turning work vehicle according to claim 4 , further comprising a safety device which restricts the revolution of the revolving superstructure and the offset of the work machine so that the bucket does not cross over the side edge of the predetermined excavation area.

6. The display system of the turning work vehicle according to claim 4 , wherein the display device displays at least the bucket and the predetermined excavation area in a plan view.

7. The display system of the turning work vehicle according to claim 4 , wherein the display device displays the side edge of the predetermined excavation area by a virtual line extending in an extending direction of the predetermined excavation area.

8. The display system of the turning work vehicle according to claim 1 , wherein a first display field shows a first position and posture of the turning work vehicle at a first state.

9. The display system of the turning work vehicle according to claim 1 , wherein the revolving superstructure and the work machine shown detached from each other on the single screen shows in a state.

10. The display system of the turning work vehicle according to claim 1 , wherein the work machine swings on a axis located at a circumference of the revolving superstructure.

11. A display method for a turning work vehicle, the display method being used for the turning work vehicle which can offset a work machine, including a bucket, relative to a revolving superstructure in a horizontal direction, the display method comprising:

calculating a position of the bucket based on a result of detection by a position detecting device installed on the turning work vehicle, and calculating a necessary revolving amount of the revolving superstructure and a necessary offset amount of the work machine that are needed to align the bucket with a predetermined excavation area;

displaying on a single screen of a display device,

information for informing about a revolving angle of the revolving superstructure according to the necessary revolving amount, and

information for informing about a swing angle of the work machine according to

the necessary offset amount,

showing, in a second display field, a second position and posture of the turning work vehicle at a second state, and

displaying, in the second display field, the revolving superstructure and the work machine detached from each other on the single screen.
