Description
Technical field
The utility model relates to a kind of electric power protection gold utensil, the stockbridge damper that particularly a kind of Anti-vibration of Overhead Transmission Line is used.
Background technology
Stockbridge damper, establishes because wind-force shame plays vibration in order to reduce wire.High-tension overhead line bar position is higher, and span is larger, when wire is subject to wind-force, does the used time, can vibrate.During conductor vibration, the condition of work of wire hanging position is the most unfavorable.Due to repeatedly vibration, wire is because periodically bending can generation fatigue rupture.When overhead transmission line span is greater than 120 meters, generally adopt stockbridge damper vibrationproof.
Existing stockbridge damper, comprises wire clamp body, steel strand wire and tup, and described wire clamp body one end is connected with cable, and the other end is fixedly connected with steel strand wire by crozier, and described tup is fixed on the two ends of steel strand wire.Because tup is fixedly connected with wire clamp body by steel strand wire, when being subject to the wind-force of fore-and-aft direction, whole stockbridge damper has the trend of rotation or produces moment rotation, and this just makes to have produced extra bending stress on cable, has accelerated the damage of cable.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of stockbridge damper, can not only guarantee vibration-isolating effect, and can not cause extra bending stress to cable in use procedure, can conscientiously guarantee the useful life of cable.
The utility model addresses the above problem by following technological means: a kind of stockbridge damper, comprise wire clamp body, steel strand wire and tup, described wire clamp body one end is connected with cable, the other end is provided with crozier, described crozier is fixedly connected with steel strand wire, described tup is fixed on the two ends of steel strand wire, between described wire clamp body and crozier, be provided with rotational structure, described rotational structure comprises that one end is fixedly connected with wire clamp body, the first connecting rod that the other end is fixedly installed outer rotary head is fixedly connected with crozier with one end, the other end is fixedly installed the second connecting rod of interior rotary head, described interior rotary head is stretched in unofficial biography head and is rotationally connected with outer rotary head.
Further, in described outer rotary head, be provided with vertical rod, described interior rotary head and vertical rod socket, be provided with spring between described interior rotary head and vertical rod, and described spring one end is connected with interior rotary head, and the other end is connected with vertical rod.
Further, on described tup, be provided with leaking hole.
The beneficial effects of the utility model: stockbridge damper of the present utility model, comprise wire clamp body, steel strand wire and tup, described wire clamp body one end is connected with cable, the other end is provided with crozier, described crozier is fixedly connected with steel strand wire, described tup is fixed on the two ends of steel strand wire, between described wire clamp body and crozier, be provided with rotational structure, described rotational structure comprises that one end is fixedly connected with wire clamp body, the first connecting rod that the other end is fixedly installed outer rotary head is fixedly connected with crozier with one end, the other end is fixedly installed the second connecting rod of interior rotary head, described interior rotary head is stretched in unofficial biography head and is rotationally connected with outer rotary head.The stockbridge damper of this structure, can not only guarantee vibration-isolating effect, and can not cause extra bending stress to cable in use procedure, can conscientiously guarantee the useful life of cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as shown in Figure 1: a kind of stockbridge damper, comprise wire clamp body 1, steel strand wire 2 and tup 3, described wire clamp body one end is connected with cable, the other end is provided with crozier 4, described crozier is fixedly connected with steel strand wire, described tup is fixed on the two ends of steel strand wire, between described wire clamp body and crozier, be provided with rotational structure, described rotational structure comprises that one end is fixedly connected with wire clamp body, the first connecting rod 6 that the other end is fixedly installed outer rotary head 5 is fixedly connected with crozier with one end, the other end is fixedly installed the second connecting rod 8 of interior rotary head 7, described interior rotary head is stretched in unofficial biography head and is rotationally connected with outer rotary head.Existence due to rotational structure, in use, when being subject to the wind-force of fore-and-aft direction, the integrative-structure being comprised of tup and the steel strand wire clamp that can wind the line freely rotates, and can not produce torsion to wire clamp body, so wire clamp body can not produce extra bending stress to cable yet, the stockbridge damper of this structure, can not only guarantee vibration-isolating effect, and can not cause extra bending stress to cable in use procedure, can conscientiously guarantee the useful life of cable.
As the further improvement of technique scheme, in described outer rotary head, be provided with vertical rod 9, described interior rotary head and vertical rod socket, be provided with spring 10 between described interior rotary head and vertical rod, and described spring one end is connected with interior rotary head, and the other end is connected with vertical rod.When being subject to the wind-force of fore-and-aft direction, interior rotary head is externally rotary head rotation mutually, spring stretches, when the abatement of wind or disappearance, spring reset, so just guarantees that the trend of two tup lines is consistent with cable trend all the time, during two tup up-down vibration, its waveform trend is also consistent with cable waveform trend, can make like this vibration-isolating effect of stockbridge damper reach best.
Further improvement as technique scheme, is provided with leaking hole 11 on described tup.When rainwater overstocks in tup, the weight that cable bears strengthens, and its fatigue rupture speed is also accelerated, and the rainwater that can guarantee in tup that arranges of leaking hole is discharged in time.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
