Abstract
The utility model relates to an antiskid damper, comprising a clamping plate (1) and a fixing bolt installed on the clamping plate (1). The antiskid damper is characterized in that a locking nut (2) is mounted on the fixing bolt, and antiskid thread patterns are arranged on the inner side of the clamping plate. According to the technical scheme of the utility model, a prior damper is improved; compared with a preformed damper, the antiskid damper is much lower in the price, greatly saves the cost and improves the cost performance; compared with the method in which rubber sheets are arranged in the clamping plate (1) to increase the static friction force between the clamping plate (1) and an earth wire, vibration-proof effect of the antiskid damper is not weakened; and compared with other existing dampers, the antiskid damper can prevent repeated sliding, greatly prolongs the service life, reduces strand breaking and wire breaking accidents of the earth wires, reduces labor intensity of maintaining staff, and provides forceful guarantee for safe production of power system.
Description
Technical field
The utility model relates to a kind of stockbridge damper of antiskid.
Background technology
Stockbridge damper is widely used in electric line, and for slackening micro-wind-induced lead wire and earth wire vibration, the protection lead wire and earth wire exempts from fatigue damage.But the installation site of stockbridge damper is most important, must calculate by strict data, if installation site is improper, vibration-isolating effect will be had a greatly reduced quality.In like manner, if can not reset in time after the stockbridge damper slippage that is in operation, just do not have the due weakening effect of stockbridge damper, the chronic fatigue operation is easy to cause the generation of disconnected thigh, disconnection fault.
The utility model content
The purpose of this utility model is to provide a kind of stockbridge damper of antiskid, can effectively prevent the slippage repeatedly of stockbridge damper, corresponding prolongation its useful life, and reduce disconnected strand of lead wire and earth wire, broken string accident.
A kind of stockbridge damper of antiskid, comprise clamping plate and be arranged on the set bolt on these clamping plate, its special feature in: on described set bolt, jam nut is installed, and is provided with anti-slip veins in the inboard of described clamping plate.
The anti-slip veins of its middle clamp plate inboard is the parallel line shaped anti-slip veins, thereby coordinates to increase frictional resistance with the aluminium armor tape gap of clamping plate installation place.
After adopting the technical solution of the utility model, after existing stockbridge damper is transformed, with Pre-Cutter-Type Anti-Vibration Hammer, compare, not only cheap a lot, greatly save cost, and can also improve cost performance.With by pad in clamping plate with sheet rubber, the method that increases the stiction of clamping plate and lead wire and earth wire is compared, and can not weaken the vibration-isolating effect of stockbridge damper.Compare with the in-service stockbridge damper of other types, can effectively prevent the slippage repeatedly of stockbridge damper, greatly increase the service life, reduce disconnected strand of lead wire and earth wire, broken string accident, reduce maintainer's labour intensity, for power system security production provides sound assurance.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of stockbridge damper of antiskid, comprise clamping plate 1 and be arranged on the set bolt on these clamping plate 1, jam nut 2 is installed on described set bolt, and the inboard at described clamping plate 1 is provided with anti-slip veins, be specially the parallel line shaped anti-slip veins, thereby coordinate to increase frictional resistance with the aluminium armor tape gap of clamping plate 1 installation place.
The utility model is installed in addition with jam nut 2 on the set bolt of stockbridge damper clamping plate 1, through evidence, is installed in addition with after jam nut 2 effect that can play good absorbing vibration energy, has effectively prevented the generation of loosening phenomenon, thereby has stopped the slippage of stockbridge damper.Also by the inboard of stockbridge damper clamping plate 1, be that the inner sunken face place arranges anti-slip veins, the degree of depth of anti-slip veins is 1 millimeter, thereby increased the stiction between clamping plate 1 and aluminium armor tape contact-making surface, fixedly after stockbridge damper, making has mutual embedded part between clamping plate 1 and aluminium armor tape gap, although may have bite mark, also is unlikely to hurt wire.Even spring shim is aging, follow the string, or the line construction personnel fail to allow it reach maximum pressure when fastening jam nut 2, or the lead wire and earth wire elongating creep, can not cause the sliding of stockbridge damper to run.
Claims (2)
1. the stockbridge damper of an antiskid, comprise clamping plate (1) and be arranged on the set bolt on these clamping plate (1), it is characterized in that: jam nut (2) is installed on described set bolt, and is provided with anti-slip veins in the inboard of described clamping plate (1).
2. the stockbridge damper of a kind of antiskid as claimed in claim 1 is characterized in that: the inboard anti-slip veins of its middle clamp plate (1) is the parallel line shaped anti-slip veins, thereby coordinates to increase frictional resistance with the aluminium armor tape gap of clamping plate (1) installation place.
