Abstract

The present invention relates to a kind of stockbridge dampers.The device includes the cast iron tup that a short steel strand wires are connected with its both ends, clamp is connected on short steel strand wires, the end of the two cast iron tup is connected with extension spring, the other end of extension spring is connected with cable, the inside of extension spring is equipped with the two oval pull rings to link together, and the both ends of pull ring are fixedly connected with cable and cast iron tup respectively.Due to the presence of extension spring, extension spring carries out energy-absorbing and flexible connection cast iron tup by the elongation of itself, to make the vibration of cable and the vibration Xiang Zhonghe of cast iron tup, effectively mitigates the shaking of cable;Simultaneously because the presence of pull ring, when cable shakes the limit of the ground amplitude beyond extension spring adjustment, the connection of cable and cast iron tup is become to be rigidly connected by pull ring, to effectively mitigate the shaking of cable, is protected extension spring, is prevented its damage.The device can be used as stockbridge damper use, safe and reliable.

Description

A kind of stockbridge damper
Technical field
The present invention relates to electric armour clamp manufacturing technology field, in particular to a kind of stockbridge damper.
Background technique
A kind of stockbridge damper, number of patent application are disclosed in existing Chinese patent database are as follows: 201420328856.7, The applying date are as follows: 2014.06.19, notification number are as follows: CN203883427U, the day for announcing are as follows: 2014.10.15, structure include: steel Twisted wire, wire clamp and at least two hammer bodies, the hammer body are fixedly mounted on the both ends of the steel strand wires, it is characterized in that: the hammer Body is equipped with the choke face for increasing itself windage.Disadvantage is that: since the device is by increasing stockbridge damper Amplitude and the vibration frequency for increasing stockbridge damper cannot efficiently reduce to close the vibration amplitude and frequency of cable in indirectly The vibration of cable, so the validity of the work of the device is unstable.
Summary of the invention
Technical problem solved by the present invention is being provided a kind of anti-on the basis of drawing and absorbing existing stockbridge damper technology Shake hammer, which matches by extension spring with pull ring, absorbing cable shake during energy while in conjunction cable Vibration amplitude and frequency, to effectively reduce the vibration of cable.
In order to realize the purpose of foregoing invention, the technical solution used in the present invention:
A kind of stockbridge damper is connected on short steel strand wires including the cast iron tup that a short steel strand wires are connected with its both ends Clamp, the end of the two cast iron tup are connected with extension spring, and the other end of extension spring is connected with cable, stretch bullet The inside of spring is equipped with the two oval pull rings to link together, and the both ends of pull ring are fixedly connected with cable and cast iron tup respectively.
When the invention works, first clamp is fixedly connected on cable, then pierces into pull ring in extension spring, will drawn One end of ring and extension spring is fixedly connected on cast iron tup, is finally fixedly connected on the other end of pull ring and extension spring On cable, when cable has slight vibration, extension spring extends while energy-absorbing, and cast iron tup is driven to shake, thus The shaking for effectively mitigating cable, when cable acutely shakes, extension spring elongation while energy-absorbing reduce the shaking of cable, draw When stretching spring and reaching maximal tensility, pull ring is tensed, and cable is made to become to be rigidly connected with cast iron tup, to effectively mitigate electric Extension spring is protected while the shaking of cable, prevents its damage.Compared with prior art, the invention has the benefit that due to The presence of extension spring, extension spring carries out energy-absorbing and flexible connection cast iron tup by the elongation of itself, to make cable The vibration Xiang Zhonghe of vibration and cast iron tup effectively mitigates the shaking of cable;Simultaneously because the presence of pull ring, when cable shakes When the limit that ground amplitude is adjusted beyond extension spring, the connection of cable and cast iron tup is become to be rigidly connected by pull ring, to have Effect ground mitigates the shaking of cable, protects extension spring, prevents its damage.The device can be used as stockbridge damper use, using safe Reliably.
It is connected for the ease of pull ring and extension spring with cable, is set on corresponding cable on the upside of the cast iron tup For connecting the connecting tube of extension spring and pull ring.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the partial enlargement diagram in Fig. 1 at A.
Wherein, 1 short steel strand wires, 2 cast iron tups, 3 clamps, 4 extension springs, 401 pull rings, 5 cables, 501 connecting tubes.
Specific embodiment
As shown in Figs. 1-2, a kind of stockbridge damper, including the cast iron tup 2 that one short steel strand wires 1 are connected with its both ends, short Clamp 3 is connected on steel strand wires 1, the end of two cast iron tups 2 is connected with extension spring 4, the other end and electricity of extension spring 4 Cable 5 is connected, and the inside of extension spring 4 is equipped with the two oval pull rings 401 to link together, the both ends of pull ring 401 respectively with Cable 5 is fixedly connected with cast iron tup 2, is connected for the ease of pull ring 401 and extension spring 4 with cable 5, on cast iron tup 2 The connecting tube 501 for connecting extension spring 4 Yu pull ring 401 is set on the corresponding cable 5 in side.
When work, first clamp 3 is fixedly connected on cable 5, while being fixedly connected with pipe 501 on cable 5, then will Pull ring 401 pierces into extension spring 4, and one end of pull ring 401 and extension spring 4 is fixedly connected on cast iron tup 2, finally will Pull ring 401 and the other end of extension spring 4 are fixedly connected in connecting tube 501, when cable 5 has slight vibration, are stretched Spring 4 extends while energy-absorbing, and cast iron tup 2 is driven to shake, to effectively mitigate the shaking of cable 5, when cable 5 is violent When shaking, the elongation of extension spring 4 while energy-absorbing reduce the shaking of cable 5, when extension spring 4 reaches maximal tensility, pull ring 401 tense, and cable 5 is made to become to be rigidly connected with cast iron tup 2, draw to effectively mitigate protection while the shaking of cable 5 Spring 4 is stretched, its damage is prevented.
The present invention is not limited to the above embodiments, on the basis of technical solution disclosed by the invention, the skill of this field For art personnel according to disclosed technology contents, one can be made to some of which technical characteristic by not needing creative labor A little replacements and deformation, these replacements and deformation are within the scope of the invention.
