Spindle-shaped sensor for monitoring load and temperature of flexible rope in real time

The invention discloses a spindle-shaped sensor for monitoring the load and the temperature of a flexible rope in real time. The spindle-shaped sensor comprises a spindle-shaped structural frame, an equal-strength cantilever, a support pillar, FBGs (fiber bragg gratings) and separation casings, wherein the spindle-shaped structural frame comprises two arch structures, and the equal-strength cantilever provided with the support pillar is connected with one side of one tip of the spindle shape; through holes are formed in the two tips of the spindle shape and the top of the support pillar, and the to-be-monitored flexible rope sequentially passes through each through hole for fixation; grooves are axially formed in upper and lower surfaces of the equal-strength cantilever and used for pasting the FBGs symmetrically; and one part, which is sleeved with the separation casing, of each grating region serves as a temperature measuring unit, the other part, which is not sleeved with the separation casing, serves as a
