Abstract
A hoist system for cable-reeling operations is disclosed herein. The hoist system includes a housing, a drum disposed within the housing and configured to spin about an axis, a motor configured to spin the drum about the axis, a cable configured to be wound and unwound from the drum as the motor spins the drum about the axis, a cable sensor configured to detect misalignment of the cable during the cable-reeling operations, and a motor controller operatively coupled to the cable sensor and the motor, wherein the motor controller is configured to receive a cable misalignment signal from the cable sensor and adjust operation of the motor in response to the cable misalignment signal.
Claims18
A hoist system for cable-reeling operations, comprising:
- a housing;
- a drum disposed within the housing and configured to spin about an axis;
- a motor configured to spin the drum about the axis;
- a cable configured to be wound and unwound from the drum as the motor spins the drum about the axis;
- a cable sensor configured to detect misalignment of the cable during the cable-reeling operations;
- and
- a motor controller operatively coupled to the cable sensor and the motor, wherein the motor controller is configured to receive a cable misalignment signal from the cable sensor and adjust operation of the motor in response to the cable misalignment signal, wherein the motor controller is further configured to receive a cable alignment signal from the cable sensor indicating that the cable is aligned and adjust operation of the motor in response to the cable alignment.
A system, comprising:
- a hoist including a drum, a motor configured to spin the drum, and a cable configured to be wound and unwound from the drum as the motor spins the drum;
- a cable sensor configured to detect a misalignment of the cable during while the cable is wound and unwound from the drum;
- a processor operatively coupled to the motor and the cable sensor;
- and
- a memory operatively coupled to the processor, the memory comprising instructions stored thereon that, when executed by the processor, cause the processor to:
- receive a cable misalignment signal from the cable sensor;
- adjust operation of the motor in response to the cable misalignment;
- receive a cable alignment signal from the cable sensor indicating that the cable is aligned;
- and
- adjust operation of the motor in response to the cable alignment signal.
A method, comprising:
- commanding, by a processor, a motor to run, the motor configured to rotate a drum to wind and unwind a cable from the drum;
- receiving, by the processor, a cable misalignment signal indicating that the cable is misaligned;
- sending, by the processor, an adjustment signal configured to adjust operation of the motor in response to the cable misalignment signal;
- receiving, by the processor, a cable alignment signal from the cable sensor indicating that the cable is aligned;
- and
- adjusting, by the processor, operation of the motor in response to the cable alignment signal.
