Abstract
The utility model discloses a kind of stockbridge damper, it comprises two tups that are connected to steel strand wire two ends and to be connected on steel strand wire and connecting rod between two tups, described connecting rod top is provided with holder, described holder comprises the subiculum and cover plate with corresponding wire clamping plate face, the relative subiculum of described cover plate arranges card thorn, and described connecting rod is positioned at below described holder and is provided with thread tensioning mechanism; Described thread tensioning mechanism comprises rotating and is arranged on rotating shaft on described connecting rod, is located at the ratchet above rotating shaft and is located at the reel of the rotating shaft other end.The utility model can while auto lock stockbridge damper, effectively prevents that the wire annexes such as stockbridge damper are sliding to be run, and greatly reduces equipment deficiency on electric power line pole tower, wire, improves the serviceability rate of operational outfit.
Description
Technical field
The utility model relates to a kind of stockbridge damper that transmission line uses.
Background technology
The effect of the meteorological conditions such as overhead power line wind-engaging, ice, low temperature, makes circuit produce vibration and wave.Vibration frequency is higher and amplitude is very little, and wind vibration makes overhead wire at suspension point place repeatedly by stubborn folding, causes fatigue of materials, finally causes disconnected stock, line-outage contingency.The frequency of waving is very low, and amplitude is very large, is easy to cause alternate flashover, causes the serious accidents such as line tripping, power failure or burn wire.Stockbridge damper is carried additionally at circuit tower bar suspension point place, to absorb or damping vibration energy, changes circuit wobble frequency, prevents the vibration of circuit or wave.
Stockbridge damper is for before eliminating circuit self-vibration and eliminating resonance that wind etc. causes, gentle breeze vibrations are principal modes of trolley wire vibrations, also be the vibrations having harm most the most often occurred, electric wire seriously can be caused to rupture, people are made to suffer tremendous economic loss, traditional stockbridge damper is generally be made up of two cast iron tups, steel strand wire and clamp, but the amplitude sometimes because of wind generation is excessive, and this design can not meet the needs of people.
In view of the defect existed in above prior art, be necessary existing apparatus to improve further, make it have more standby practicality, could realistic service condition.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of stockbridge damper.
The utility model is taked following technical scheme to realize: a kind of stockbridge damper, it comprises two tups that are connected to steel strand wire two ends and to be connected on steel strand wire and connecting rod between two tups, described steel strand wire casting is arranged in connecting rod, described connecting rod top is provided with holder, described holder comprises the subiculum and cover plate with corresponding wire clamping plate face, the relative subiculum of described cover plate arranges card thorn, inwardly, described connecting rod is positioned at below described holder and is provided with thread tensioning mechanism the thorn point of this card thorn; Described thread tensioning mechanism comprise rotate be arranged on rotating shaft on described connecting rod, be located at above rotating shaft ratchet and be located at the reel of the rotating shaft other end.
Concrete, one end of rotating shaft of the present utility model is provided with the ratchet corresponding with described ratchet; The card thorn that card thorn of the present utility model is controllable rotation direction, length is adjustable, quantity is 1 to 3; When folded diameter of wire is at below 240mm, the quantity of card thorn is 1.
The utility model has following beneficial effect in sum: the utility model structure is simple, design ingenious, can while auto lock stockbridge damper, effectively prevent the sliding race of the wire annexes such as stockbridge damper, greatly reduce equipment deficiency on electric power line pole tower, wire, thus the duplication of labour probability effectively reduced on shaft tower and interruption duration, improve the serviceability rate of operational outfit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model holder.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
As shown in the figures 1 and 2, the utility model is taked following technical scheme to realize: a kind of stockbridge damper, it comprises two tups (4 being connected to steel strand wire 3 two ends, 8) and to be connected on steel strand wire 3 and to be positioned at two tups (4, 8) connecting rod 7 between, described steel strand wire 3 casting is arranged in connecting rod 7, described connecting rod 7 top is provided with holder 1, described holder 1 comprises the subiculum 13 and cover plate 11 with corresponding wire clamping plate face, described cover plate 11 relatively subiculum 13 arranges card thorn 12, the thorn point of this card thorn 12 inwardly, described connecting rod 7 is positioned at below described holder 1 and is provided with thread tensioning mechanism.
Preferably, thread tensioning mechanism of the present utility model comprise rotate be arranged on rotating shaft 6 on described connecting rod 7, be located at above rotating shaft 6 ratchet 5 and be located at the reel 2 of rotating shaft 6 other end.
Preferably, one end of rotating shaft 6 of the present utility model is provided with the ratchet corresponding with described ratchet 5.
Preferably, the card thorn that card thorn 12 of the present utility model is controllable rotation direction, length is adjustable, quantity is 1 to 3.
Concrete enforcement: when folded diameter of wire is at below 240mm, the quantity of card thorn 12 is 1.
The utility model can while auto lock stockbridge damper, effectively prevents that the wire annexes such as stockbridge damper are sliding to be run, and greatly reduces equipment deficiency on electric power line pole tower, wire, improves the serviceability rate of operational outfit.
The above is embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
