Floating type shock absorber with rigidity

Abstract

The invention discloses a floating type shock absorber with rigidity. The shock absorber comprises a rigidity device and two stabilizing devices. The rigidity device comprises a connecting rod, the connecting rod is horizontally arranged, the two stabilizing devices correspond to the two ends of the connecting rod in a one-to-one mode, the stabilizing devices are installed at the ends of the corresponding connecting rod, and each stabilizing device comprises an upper installation plate, a lower installation plate and at least two damping devices. The shock absorber has the advantages that theself-vibration frequency of the damper is adjusted through the rigidity device, so that the movement of the mass unit and the controlled structure generates displacement and speed difference, nonlinear energy consumption is conducted through the damping device, the wires are restrained through the multiple spacers, mutual attraction and collision of the wires are prevented, wire harness vibrationis eliminated and reduced, and up-down waving of the wire harness is prevented. And the torsional rigidity of the split power transmission line is improved by utilizing the two stabilizing devices, sothat the torsional motion of the electric wire is also consumed while the vertical motion is controlled, and the safety of the power transmission line is protected to a greater extent.

Problems solved by technology

[0002] In the overhead EHV transmission, compared with the single guide, the split guide can reduce the inductance of the transmission line and increase the capacitance, so that the wave impedance to the alternating current can be reduced, and the power transmission capacity of the line can be improved. In order to ensure the split wire harness Keep the spacing constant to meet the electrical performance, reduce the surface potential gradient, and in the case of a short circuit, the electromagnetic force will not be generated between the guide wires, causing mutual attraction and collision, or even if it causes an instantaneous attraction collision, it can return to the normal state after the accident is eliminated. , it is necessary to install spacer rods and pendulums at a certain distance in the span. Installing spacer rods can eliminate and reduce the vibration of the wire harness and prevent the wire harness from galloping up and down. Because the galloping of the split wires is often accompanied by torsional motion, and the torsional motion is very important for the galloping excitation. It is very important, but if only spacers are installed, the ability to suppress the overhead wires in the horizontal and torsional direction and other galloping directions is poor. While the pendulum is in the process of swinging, although the larger galloping of the wires is suppressed, the amplitude is larger. , poor damping effect
