Abstract
The utility model discloses a circular shockproof hammer structure which includes an outer circular wall, and a central circular table which is arranged at the center of the outer circular wall. A plurality of springs are connected between the side wall of the central circular table and the inner wall of the outer circular wall; and a top connecting seat of the central circular table is internally provided with a line hanging through hole. The circular shockproof hammer structure has the better shock-absorbing effect, and greatly improves the service life of the overhead wire.
Description
Technical field
the utility model relates to stockbridge damper field, is specially a kind of circular vibration hammer structure.
Background technology
Trolley wire is subject to the meteorological condition effects such as wind, ice, can produce that frequency is higher, amplitude is less vibration and wave, thereby affect useful life of trolley wire, in electric power transfer, the general stockbridge damper that adopts absorbs or weakens the vibration of trolley wire and wave.The stockbridge damper of prior art carries out damping by the pendulum swing of both sides mostly, and damping effect is poor.
Utility model content
The purpose of this utility model is to provide a kind of circular vibration hammer structure, to solve the poor problem of prior art stockbridge damper damping effect.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of circular vibration hammer structure, it is characterized in that: include external annulus, and the center round platform that is arranged on external annulus center, between described center round platform sidewall and external annulus inwall, be connected with a plurality of springs, and a plurality of springs distribute along center round platform even circumferential, round platform top, described center is connected with Connection Block, is provided with the hanging wire through hole parallel with round platform top, center table top in Connection Block.
Described a kind of circular vibration hammer structure, is characterized in that: around described spring You Liuge， interval 60 degree are distributed in center round platform along even circumferential.
The utility model carries out damping by a plurality of springs that are connected between external annulus and center round platform, has good damping effect, has greatly improved the useful life of trolley wire.
Accompanying drawing explanation
Fig. 1 is the utility model structure vertical view.
Fig. 2 is the utility model structure side cutaway view.
Embodiment
As shown in Figure 1 and Figure 2.A kind of circular vibration hammer structure, include external annulus 1, and the center round platform 2 that is arranged on external annulus 1 center, between center round platform 2 sidewalls and external annulus 1 inwall, be connected with a plurality of springs 3, and a plurality of springs 3 distribute along center round platform 2 even circumferentials, round platform 2 tops in center are connected with Connection Block 4, are provided with the hanging wire through hole 5 parallel with center round platform 2 top table tops in Connection Block 4.Around spring 3 You Liuge， interval 60 degree are distributed in center round platform 2 along even circumferential.
