Tension sensor assembly

摘要

A tension detector may detect and help correct tension in a lift cable. The cable may include a lift cable within a telescopic structure, such as a telescopic tower. The tension sensor may detect when the cable tension is outside a high tension threshold and a low tension threshold and trigger an alert when outside the thresholds. The alert may be an audible alert or a visual alert. A controller may prevent a user from making the tension worse and encourage an operator to correct the tension problem by preventing a winch from expanding or retracting the telescopic structure. The tension sensor may use springs to calibrate the thresholds for the high tension and low tension and a series of pulleys to manipulate an arm to engage a tension sensor.

1. A tension sensor system for sensing tension of a cable, comprising:
a high-tension arm mounted on a first pivot and biased to rotate the high-tension arm along a first arc in a first direction; a low-tension arm mounted on a first pivot and biased to rotate the low-tension arm along a second arc in a first direction; a first pulley mounted on the high-tension arm and adapted to receive a cable such that tension on the cable exerts a force to rotate the high-tension arm along the first arc in a second direction; a second pulley mounted on the low-tension arm and adapted to receive the cable such that tension on the cable exerts a force to rotate the low-tension arm along the second arc in a second direction; a high-tension sensor configured to output a signal when the high-tension arm rotates to a high-tension position; and a low-tension sensor configured to output a signal when the low-tension arm rotates to a low-tension position.
