A shovel includes a traveling undercarriage, an upper rotating structure swingably mounted on the traveling undercarriage, an attachment attached to the upper rotating structure and including a boom, an arm, and an end attachment, and a display device. The display device is configured to display the attitude information of the end attachment in a three-dimensional model that enables three-dimensional visual recognition of the attitude information. The three-dimensional model is displayed in accordance with the attitude of the end attachment.
1. A shovel comprising:
a traveling undercarriage;
an upper rotating structure swingably mounted on the traveling undercarriage;
an attachment attached to the upper rotating structure and including a boom, an arm, and an end attachment; and
a display device configured to display a three-dimensional model that displays attitude information of the end attachment in such a manner as to enable three-dimensional visual recognition of the attitude information relative to a target surface, the three-dimensional model being configured to display a change in a relative angle of the end attachment to the target surface as a change in an area of a plane image of the three-dimensional model.
2. The shovel as claimed in claim 1 , wherein a center line is formed in the three-dimensional model.
3. The shovel as claimed in claim 2 , wherein the center line is a transverse center line, and the three-dimensional model is configured to turn about the center line serving as a central axis in accordance with the relative angle of the end attachment to the target surface in a side view.
4. The shovel as claimed in claim 2 , wherein the center line is a longitudinal center line, and the three-dimensional model is configured to turn about the center line serving as a central axis in accordance with the relative angle of the end attachment to the target surface in a top plan view.
5. The shovel as claimed in claim 2 , wherein the three-dimensional model is configured to turn clockwise or counterclockwise in accordance with the relative angle of the end attachment to the target surface in a front view.
6. The shovel as claimed in claim 1 , wherein
the three-dimensional model internally includes a transverse plane passing through a center and a longitudinal plane passing through the center, and
the transverse plane and the longitudinal plane are translucently displayed and are colored.
7. The shovel as claimed in claim 1 , wherein the three-dimensional model has a circular shape.
8. The shovel as claimed in claim 1 , wherein a bar representation representing a relationship between a height of a working part and a height of the target surface is displayed together with the three-dimensional model.
9. The shovel as claimed in claim 8 , wherein the bar representation includes a plurality of bar representations that are displayed one with respect to each of ends of the working part.
10. The shovel as claimed in claim 9 , wherein the bar representations are displayed one on each of opposite sides of the three-dimensional model.
11. The shovel as claimed in claim 1 , wherein at least one of the relative angle of the end attachment to the target surface in a side view, the relative angle of the end attachment to the target surface in a top plan view, and the relative angle of the end attachment to the target surface in a front view is displayed in a region adjacent to the three-dimensional model.
12. A display device for a shovel, the shovel including a traveling undercarriage, an upper rotating structure swingably mounted on the traveling undercarriage, and an attachment attached to the upper rotating structure and including a boom, an arm, and an end attachment, wherein:
the display device is configured to display a three-dimensional model that displays attitude information of the end attachment in such a manner as to enable three-dimensional visual recognition of the attitude information relative to a target surface, the three-dimensional model being configured to display a change in a relative angle of the end attachment to the target surface as a change in an area of a plane image of the three-dimensional model.
