Example Embodiment

[0012] Specific embodiment one: combination figure 1 To explain this embodiment, a line shock-proof hammer with adjustable resonance frequency in this embodiment includes a wire clamp assembly 1 and a protective wire cover 4, the protective wire sleeve 4 is sleeved on the wire 5, and the wire clamp assembly 1 is installed on the protective wire sleeve 4 Above, the line anti-vibration hammer also includes a middle support plate 2, two resonance devices 3, a first connecting rod 11, a lower support plate 12, a first rotating part 13, a screw 14, a second rotating part 15, a pressure plate 16, a step Into the motor 17, the worm gear 19, the second connecting rod 20 and the rotating rod 21, the middle support plate 2 is connected to the lower end of the wire clamp assembly 1 by screws, the lower support plate 12 is installed at the lower end of the middle support plate 2, and the stepping motor 17 passes The pressure plate 16 is installed on the lower support plate 12, the output e...

Example Embodiment

[0013] Specific implementation manner two: combination figure 1 To illustrate this embodiment, the line shock-proof hammer of this embodiment further includes a first fixed head 10 and a second fixed head 18. The other end of the first connecting rod 11 and the other end of the second connecting rod 20 respectively pass through the first fixed head 10. And the second fixed head 18 is rotatably connected with a resonance device 3. This arrangement facilitates the smooth rotation of the resonance device 3 and also facilitates the connection of the other end of the first connecting rod 11 and the other end of the second connecting rod 20 with the first fixed head 10 and the second fixed head 18. The other composition and connection relationship are the same as in the first embodiment.

Example Embodiment

[0014] Specific implementation mode three: combination figure 1 To describe this embodiment, both the first rotating member 13 and the second rotating member 15 of this embodiment are bearings. Such a setting facilitates weight reduction and flexible rotation. Other components and connection relationships are the same as those in the first or second embodiment.

Abstract

The invention discloses a line anti-vibration hammer capable of adjusting resonant frequencies, relates to a line anti-vibration hammer, and aims at solving the problems that the existing antivibrator only can be matched with several resonant frequencies, and a resonance vibration attenuation effect cannot be exerted on other numerous frequencies. A line sheath of the line anti-vibration hammer disclosed by the invention covers a lead; a clip assembly is arranged on the line sheath; a middle support plate is connected with the lower end of the clip assembly through bolts; a bottom support plate is arranged at the lower end of the middle support plate; a stepping motor is arranged on the bottom support plate through a pressing plate; the output end of the stepping motor is connected with a screw; two ends of the screw are respectively supported by a first rotating part and a second rotating part and are rotatably connected; a worm wheel is arranged on the bottom support plate above the screw; the middle part of a rotating lever is rotatably arranged on the middle support plate; two ends of the rotating lever are respectively and rotatably connected with one end of a first connecting rod and one end of a second connecting rod; the other end of the first connecting rod and the other end of the second connecting rod are respectively and rotatably connected with a resonant device. The line anti-vibration hammer disclosed by the invention is used for resonant frequency adjustment of an overhead line.

Description

technical field [0001] The invention relates to an anti-vibration hammer for overhead lines, in particular to a line anti-vibration hammer with adjustable resonant frequency. Background technique [0002] Breeze vibrations of transmission lines and wind vibrations of transmission towers often cause extremely harmful faults such as broken strands and broken wires of transmission lines, node connection damage of poles and towers, and many times caused serious large-scale power outages. There are three forms of wind-induced conductor vibration of overhead transmission lines: breeze vibration, sub-gap vibration and galloping, among which the breeze vibration of conductors occurs most frequently and has the greatest impact. The breeze vibration of the wire is due to the periodic "Karman vortex" excitation behind the wire when the wind blows through the wire vertically, which generates a force on the wire perpendicular to the wire and the wind direction, causing the wire to genera...
