WIRE SENSOR, AND DECELERATION STRUCTURE AND HIGH-SPEED ROTATION PREVENTION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a wire sensor that can reduce or prevent a risk of accidents during wire cutting by keeping a wire from swinging easily when the wire is cut and wound up.SOLUTION: A wire sensor deceleration structure 10 comprises an axis 1 of a wire winding-up drum 7 and a rotation axis 2 on the same axis, a clutch shoe part 3 provided on the periphery of the rotation axis 2, and a non-rotation clutch case 4 provided outside the clutch shoe part 3. The clutch shoe part 3 is energized to the rotation axis 2 by elasticity and makes contact with the clutch case 4 when it has exceeded a certain rotation speed to brake the rotation axis 2.
