Description

An Anti-vibration Hammer that Can Utilize Viscous Damping to Suppress Vibration

technical field

The utility model relates to an anti-vibration hammer, in particular to an anti-vibration hammer which can utilize viscous damping to suppress vibration.

Background technique

Under normal circumstances, the conductor is in a state of vibration all the time, which will affect the performance of the transmission conductor or cause fatigue and broken strands, resulting in economic losses. In actual engineering, anti-vibration hammers are often used to reduce the amplitude of vibration. But the existing anti-vibration hammer mostly adopts the solid hammer head type, which utilizes the vibration of the hammer head and the frictional energy consumption of the steel strand strands. The form is single, and the structural characteristics of itself cannot be fully utilized, and the effect is not very satisfactory. Moreover, through some engineering cases and field experiments that have been built across transmission lines, we found that under long-term vibration, the connection between the fixed clamp and the anti-vibration hammer head and the steel strand is prone to slippage and serious wear. This has just greatly reduced the anti-vibration performance of anti-vibration hammer, affects the life-span of electric transmission lead, serious also needs to change new fittings, expends a large amount of manpower and material resources.

Utility model content

The utility model sets the anti-vibration hammer head as a cavity structure on the basis of the existing anti-vibration hammer. The cavity structure is filled with an appropriate amount of viscous liquid, and a throttling orifice plate is arranged transversely in the middle of the cavity structure. When the liquid passes through the throttling orifice, shear viscous force will occur to achieve the purpose of energy dissipation and vibration reduction.

In order to solve the above-mentioned technical problems, the utility model proposes the following technical solutions: an anti-vibration hammer that can utilize viscous damping to suppress vibration, which includes an anti-vibration hammer head, and the connection between the anti-vibration hammer head and the end of the steel strand is provided with a Compression sleeve, the compression sleeve adopts a three-lobed split structure, which includes a cylindrical end and a conical end, the cylindrical end is embedded in the connection hole of the anti-vibration hammer head, and the external sleeve of the conical end is equipped with an adjustment nuts.

A compression sleeve is also installed at the position where the steel strand is in contact with the fixed clamp, the cylindrical end of the clamp is embedded in the connection hole of the fixed clamp, and an adjusting nut is sleeved outside the conical end.

The anti-vibration hammer head adopts a cavity structure, and a throttling orifice plate and viscous liquid are placed inside the cavity.

A layer of rubber is inlaid inside the compression sleeve.

The utility model has the following beneficial effects:

This patent is made according to the principle of fluid movement, especially when the fluid passes through the orifice, throttling resistance will be generated, and there is a fixed compression sleeve at the connection between the steel strand and the fitting for secondary reinforcement. The contact area between the clamp and the steel strand can be increased to prevent the steel strand from slipping. There is a rubber pad inside the compression sleeve, which can protect the steel strand at the sleeve from abrasion. The anti-vibration hammer has a novel structure and low cost, can realize the purpose of energy consumption and anti-vibration, and can prevent the slippage of steel strands, and can provide a new design idea for the development and research of anti-vibration fittings.

Working process and working principle of the present utility model are:

An anti-vibration hammer that can use viscous damping to suppress vibration. When the breeze vibrates, the wire vibrates, and the anti-vibration hammer installed on the wire will vibrate accordingly, so that the viscous liquid in the cavity will pass through the orifice when vibrating , thus producing a kind of shear viscous resistance to suppress the vibration, the vibration of the hammer head and the friction between strands and strands will also dissipate part of the wind energy.

One end of the sleeve with a small diameter extends into the clamp and the hammer head, and the other end is exposed on the steel strand. The inner sleeve and There is a step-like protrusion at the connection of the outer sleeve. After the outer sleeve is fixed by bolts, the protrusion can withstand the clamp and the hammer head to prevent slippage. And there is a rubber pad in the casing to prevent friction damage between the hardware and the steel strand.
