Embodiment Construction
[0111] For purposes of illustrating the preferred embodiments of the present invention, reference will now be made in detail to the accompanying drawings, Figure 1A shows an excavator 6 provided with a position detection device according to the invention. Excavator 6 includes a cab 32 and boom 8 attached to mounting structure 12 which is rotatably attached to cab 32 by a shaft (not shown) having a longitudinal axis when excavator 6 is arranged in a horizontal On the surface, the longitudinal axis extends vertically.
[0112] Excavator 6 includes a swing cylinder 34 extending between mounting structure 12 and cab 32 . The rotary cylinder 34 is arranged to rotate the mounting structure 12 relative to the longitudinal axis of the shaft when actuated. Thus, by controlling the swivel cylinder 34 it is possible to swivel the mounting structure 12 and thus the boom 8 relative to the longitudinal axis of the shaft.
[0113] The excavator 6 includes a position detection device with...

A position detection device (2) for detecting a position of a bucket (4) of an excavator (6) having a cab (32) and one or more boom arms (8) is disclosed. The excavator (6) comprises a first boom (8) rotatably attached to the cab (32) by a mounting structure (12) rotatably attached to the cab (32) by a shaft (14) having a longitudinal axis (X) extending substantially vertically during normal use of the excavator (6). The bucket (4) is rotatably mounted to an arm (24) that is rotatably attached to a first boom (8) or to a second boom that is rotatably attached to the first boom (8). The cab (32) has a longitudinal axis (Y) and a transverse axis (X) extending perpendicular to the longitudinal axis. The mounting structure (12) is arranged and configured to allow rotation of the first boom (8) relative to the longitudinal axis (Z) of the shaft (14). The position detection device (2) comprises one or more antennas (20) arranged and configured to receive satellite signals from one or more satellites. The position detection device (2) comprises a sensor assembly (10) configured to detect an angular position (alpha) of the first boom (8) relative to a rotation about a longitudinal axis (Z) of the shaft (14).
Description
technical field [0001] The invention relates to a device and method for detecting the position of an excavator bucket. The present invention more particularly relates to an apparatus and method for detecting the position of one or more structures of a bucket of an excavator having a cab and a bucket rotatably mounted to an arm, the A stick is rotatably attached to a boom of an excavator including a boom rotatably attached to a cab by a mounting structure. The boom is arranged to rotate relative to a vertical axis and a horizontal axis. Background technique [0002] An excavator is a digging machine usually mounted on tracks or wheels. A typical excavator has a bucket mounted on the end of a two-member or three-member linkage. When an excavator has a bucket mounted to the end of a two-member linkage, one of the linkages, called the boom, is pivotally mounted to the excavator's mounting structure and extends outward in an upward direction. One end of another link, often ca...
