Abstract
The invention relates to a shockproof hammer comprising two hammer bodies which are connected by a connecting rod. An installation fixture for wire connection is fixedly installed in the middle of the connecting rod. The two hammer bodies are of the same structure, size and weight. Each hammer body comprises a connecting part disposed at the outer side and used for being connected with the connecting rod, the inner end of the connecting part is connected with two shock absorption parts which are arranged in parallel and can move axially, and the two shock absorption parts are symmetrically distributed about the axis of the connecting rod. Each shock absorption part comprises a cylinder part connected with the corresponding connecting part and a round head part connected with the cylinder part, and the round head part and the cylinder part are connected by an arc transition. The shockproof hammer of the invention can effectively absorb or weaken vibrating and galloping of overhead lines and prolong the service life of overhead lines.
Description
Technical field
The invention belongs to stockbridge damper technical field, be specifically related to a kind of stockbridge damper.
Background technology
At present, on ultra-high-tension power transmission line, trolley wire is subject to the meteorological condition effect such as wind, ice, can produce frequency is higher, amplitude is less vibration and wave, thus affecting the service life of trolley wire, in electric power transmits, being generally adopted stockbridge damper absorb or weaken the vibration of trolley wire and wave.
The stockbridge damper of prior art, is mostly swung by the column pendulum of both sides and carries out damping, and this stockbridge damper damping effect is not so good, can cause that wire is damaged because damping effect is bad.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem and a kind of stockbridge damper is provided, it is intended to solve existing stockbridge damper design unreasonable structure, the technical problem that damping effect is bad.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of stockbridge damper, including two hammer bodies, said two hammer body is connected by connecting rod, the middle part of described connecting rod is installed with the installation fixture connected for wire, said two hammer body structure is identical, in the same size, and weight is identical, including the connecting portion for being connected with connecting rod being positioned at outside, the medial extremity of described connecting portion connects two axially displaceable damping portion be arrangeding in parallel, two described damping portion are distributed with the axisymmetrical of described connecting rod, described damping portion includes a trunk portion connected with described connecting portion, one round head connected with described trunk portion, described round head is connected by arc-shaped transition with described trunk portion.
A part for described trunk portion is socketed in the cavity in described connecting portion, is provided with damping spring in the cavity of described connecting portion.
Part in the cavity being socketed in described connecting portion of described trunk portion has a bellend, and the inside bending of outboard end of described cavity forms bending Access Division, for matching with described bellend, it is prevented that described trunk portion skids off described cavity.
Two hammer bodies of stockbridge damper of the present invention, said two hammer body is connected by connecting rod, the middle part of described connecting rod is installed with the installation fixture connected for wire, said two hammer body structure is identical, in the same size, and weight is identical, including the connecting portion for being connected with connecting rod being positioned at outside, the medial extremity of described connecting portion connects two axially displaceable damping portion be arrangeding in parallel, two described damping portion are distributed with the axisymmetrical of described connecting rod, described damping portion includes a trunk portion connected with described connecting portion, one round head connected with described trunk portion, described round head is connected by arc-shaped transition with described trunk portion, can effectively absorb or weaken the vibration of trolley wire and wave, thus extending the service life of trolley wire.
Accompanying drawing explanation
Fig. 1 show the structural representation of the stockbridge damper that the embodiment of the present invention provides;
Fig. 2 show the trunk portion of damping portion and the attachment structure schematic diagram of connecting portion.
Detailed description of the invention
Below, it is further described in conjunction with the example substantive distinguishing features to the present invention and advantage, but the invention is not limited in listed embodiment.
Refer to shown in Fig. 1��2, a kind of stockbridge damper, including two hammer bodies 1, 2, said two hammer body is connected by connecting rod 4, the middle part of described connecting rod 4 is provided with installation fixture 3, described hammer body 1, 2 structures are identical, in the same size, and weight is identical, as shown in Figure 1, described hammer body 1 includes the connecting portion 11 for being connected with described connecting rod 4, the inner of described connecting portion 11 connects two axially displaceable damping portion 12 be arrangeding in parallel, two damping portion 12 are distributed with the axisymmetrical of described connecting rod 4, including a trunk portion 120, one round head 121, described round head 121 is connected with described trunk portion 120 arc-shaped transition, side is seen the shape being similar to bulb.
The present invention is arranged by above hammer body structure so that stockbridge damper has better damping effect.
A part for described trunk portion 120 is socketed in the cavity 110 in described connecting portion 11, three damping springs 13 it are provided with in the cavity 110 of described connecting portion 11, described damping spring 13 is enclosed within a guide post, two terminations of described guide post and the installing hole of the inner bottom part of described cavity 110 and described trunk portion 120 stretch in the installing hole of the medial extremity of the part in this cavity, and this guide post is under spring is not compressed state, namely under home state, its this end with described state trunk portion 120 stretch into part in this cavity medial extremity installing hole hole bottom keep certain predetermined distance, thus forming the stroke space that this trunk portion 120 is predetermined in cavity, and do not result in guide post and skid off installing hole.
Part in the cavity 110 being socketed in described connecting portion 11 of described trunk portion 120 has a bellend 121, the inside bending of outboard end of described cavity 110 forms bending Access Division 111, for matching with described bellend 121, it is prevented that described trunk portion 120 skids off described cavity 110.
Described connecting rod 4 can adopt steel strand wires, it would however also be possible to employ other material.
By above technical scheme, can be seen that, two hammer bodies of stockbridge damper of the present invention, said two hammer body is connected by connecting rod, the middle part of described connecting rod is installed with the installation fixture connected for wire, said two hammer body structure is identical, in the same size, and weight is identical, including the connecting portion for being connected with connecting rod being positioned at outside, the medial extremity of described connecting portion connects two axially displaceable damping portion be arrangeding in parallel, two described damping portion are distributed with the axisymmetrical of described connecting rod, described damping portion includes a trunk portion connected with described connecting portion, one round head connected with described trunk portion, described round head is connected by arc-shaped transition with described trunk portion, can effectively absorb or weaken the vibration of trolley wire and wave, thus extending the service life of trolley wire.
