The utility model discloses an overhead distribution line pre-stranding type binding wire
fatigue testing machine device, include: frame, guardrail, left fixed unit, left motion unit, support unit, right motion unit, right fixed unit, control box, left fixed unit and right fixed unit be by screw, nut,
force sensor, fixed ring constitute, for the measured
electric wire is fixed in the both ends of device, left motion unit and right motion unit be by
servo electric
jar, wire clamp constitute, and it is located respectively in the intermediate position of left, right fixed unit and support unit, for the measured
electric wire produces synchronous
reciprocating motion's excitation, support unit, and it is via insulator and the recess on it and support the measured
electric wire. The
fatigue testing machine device above, and the equipment structure is simple and easy to manufacture, and
system loading holds the load stability, and two -way dynamic collaborative control, and the force value precision is high, can satisfy each fatigue
test specification technical requirement.
