Movement system configured for moving a payload in a plurality of directions

摘要

A movement system includes a bridge crane, a trolley, and a movement device. The movement device includes an attachment portion, a plurality of housings, first and second curved elements, a cable, and a cable angle sensor. The curved elements are pivotally attached to housings and perpendicularly overlap with one another such that a first slot defined in the first curved element is perpendicular to a second slot defined in the second curved element. The first curved element is pivotable about a first axis and the second curved element is configured to pivot about a second axis. The cable extends from the attachment portion and through each of the slots. The cable is pivotable to angularly displace at least one of the curved elements about a respective axis. The cable angle sensor is configured to measure the angular displacement of the at least one of the first and second curved elements.

1. A movement device configured determine a direction of intended movement of a payload, the movement device comprising:
an attachment portion; a plurality of housings operatively extending from the attachment portion; a first curved element and a second curved element extending between respective ends; wherein the ends of the first and second curved elements are pivotally attached to a respective one of the plurality of housings; wherein each of the first and second curved elements forms a partial circle; wherein the first curved element defines a first slot and the second curved element defines a second slot; wherein the first curved element perpendicularly overlaps with the second curved element such that the first slot of the first curved element is in perpendicular relationship to the second slot of the second curved element; wherein the first curved element is configured to pivot about a first axis and the second curved element is configured to pivot about a second axis, which extends in perpendicular relationship to the first axis; a cable extending from the attachment portion and through each of the first slot and the second slot; wherein the cable is configured to pivot relative to the attachment portion such that the cable angularly displaces at least one of the first and second curved elements about the respective first and second axis; and a cable angle sensor configured to measure the angular displacement of the at least one of the first and second curved elements.
