Title:
WIRE PRE-TWISTED DAMPER
Document Type and Number:
WIPO Patent Application WO/2020/062323
Kind Code:
A1
Abstract:
Disclosed is a wire pre-twisted damper, comprising a strand clamp body (1), galvanized steel strands (2), a damper head (3), a strand clamp pressing plate (4), a stop pin (5), a split pin (6), a hinge pin (7), a preformed armor rod (9) and a rotation fixing component (11), wherein the strand clamp pressing plate (4) is fixed to the top of the strand clamp body (1) by means of a screw; the top of the strand clamp pressing plate (4) is sleeved with the hinge pin (7), and the bottom of the strand clamp pressing plate (4) is sleeved with the split pin (6); and two ends of the bottom of the strand clamp body (1) are both sleeved with the galvanized steel strands (2). The wire pre-twisted damper has a simple structure and is easily operated; wires are fixed inside the strand clamp pressing plate (4) by using the preformed armor rod, thereby preventing shifting of the wire pre-twisted damper; the stand clamp pressing plate (4) is fixed at the top of the stand clamp body (1) by means of the split pin (6) and the stop pin (5), and is easily mounted and removed; and vibration phases of the damper head and the wires are in opposition, such that vibration of the wires is eliminated, and the vibration of the wires is greatly reduced, thereby preventing periodic bending and fatigue failure of the wires due to multiple vibrations, facilitating the protection of the wires and prolonging the service life of the wires.
