Abstract
A system for determining an angular position of a boom of a pipelayer is disclosed. The system includes a linkage, an angle sensor, and a controller. The linkage includes a first arm configured to be coupled to a frame of the pipelayer, a second arm configured to be coupled to the boom, and a pivot joint pivotally connecting the first arm to the second arm. The angle sensor is positioned at the pivot joint. The angle sensor is configured to detect a pivot angle between the first arm and the second arm. The controller is configured to determine, based on the pivot angle, the angular position of the boom relative to the frame of the pipelayer.
Claims20
A system, comprising:
- a linkage, comprising:
- a first arm directly coupled to a frame, of a pipelayer, supporting a boom of the pipelayer,
- a second arm directly coupled to a leg of the boom, and
- a pivot joint pivotally connecting the first arm to the second arm;
- an angle sensor, at the pivot joint, configured to detect a pivot angle between the first arm and the second arm;
- and
- a controller configured to determine, based on the pivot angle, an angular position of the boom relative to the frame of the pipelayer.
A pipelayer, comprising:
- a frame supporting a boom pivotally coupled to the frame at a pin joint;
- and
- a system, including:
- a linkage, comprising:
- a first arm directly coupled to the frame,
- a second arm coupled to the boom, and
- a pivot joint pivotally connecting the first arm to the second arm;
- an angle sensor, at the pivot joint, configured to detect a pivot angle between the first arm and the second arm;
- and
- a controller configured to determine, based on the pivot angle, an angular position of the boom relative to the frame of the pipelayer.
A method, comprising:
- detecting, via an angle sensor positioned at a pivot joint pivotally connecting a first arm and a second arm of a linkage, a pivot angle between the first arm and the second arm, wherein the first arm is directly coupled to a frame of a pipelayer supporting a boom of the pipelayer, and the second arm is directly coupled to a second arm directly coupled to a leg of a boom;
- and
- determining, based on the pivot angle, an angular position of the boom relative to the frame of the pipelayer.
