Abstract
The present invention relates to a kind of stockbridge damper.The device includes the cast iron tup that a short steel strand wires and its two ends are connected, clamp is connected with 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 provided with the two oval draw rings linked together, and the two ends of draw 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, so that the vibrations of cable effectively mitigate rocking for cable with being closed in the vibrations phase of cast iron tup；Simultaneously because the presence of draw ring, when cable rocks 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 draw ring, so as to effectively mitigate rocking for cable, is protected extension spring, is prevented it from damaging.The device can be used as stockbridge damper, and its is safe and reliable.
Description
Technical field
The present invention relates to electric armour clamp manufacturing technology field, more particularly to a kind of stockbridge damper.
Background technology
A kind of stockbridge damper is disclosed in existing Chinese patent database, its number of patent application is：201420328856.7,
The applying date is：2014.06.19, notification number is：CN203883427U, the day for announcing is：2014.10.15, its structure includes：Steel
Twisted wire, wire clamp and at least two hammer bodies, the hammer body are fixedly mounted on the two ends of the steel strand wires, it is characterized in that：The hammer
Body is provided with the choke face for being used for increasing itself windage.It is disadvantageous in that：Because the device is by increasing stockbridge damper
The vibration frequency of amplitude and increase stockbridge damper, so as to close the vibration amplitude and frequency of cable in indirect, it is impossible to efficiently reduce
The vibrations of cable, so the validity of the work of the device is unstable.
The content of the invention
Present invention solves the technical problem that being：It is anti-there is provided one kind on the basis of drawing and absorbing existing stockbridge damper technology
Shake hammer, the device is engaged by extension spring with draw ring, while energy during absorbing cable vibrations in conjunction cable
Vibration amplitude and frequency, so as to effectively reduce the vibrations of cable.
In order to realize the purpose of foregoing invention, the technical solution used in the present invention：
A kind of stockbridge damper, including the cast iron tup that a short steel strand wires and its two ends are connected, are connected with short steel strand wires
Clamp, the end of the two cast iron tup is connected with extension spring, and the other end of extension spring is connected with cable, stretches bullet
The inside of spring is provided with the two oval draw rings linked together, and the two ends of draw ring are fixedly connected with cable and cast iron tup respectively.
During present invention work, first clamp is fixedly connected on cable, then pierced into draw ring in extension spring, will be drawn
One end of ring and extension spring is fixedly connected on cast iron tup, is finally fixedly connected on the other end of draw ring and extension spring
On cable, when cable has slight vibrations, extension spring extends while energy-absorbing, drives cast iron tup to rock, so that
Effectively mitigate rocking for cable, when cable is acutely rocked, extension spring elongation energy-absorbing, rocking for reduction cable simultaneously is drawn
When stretching spring and reaching maximal tensility, draw ring is tensed, and makes cable become to be rigidly connected with cast iron tup, so as to effectively mitigate electric
Cable protects extension spring while rocking, prevent it from damaging.Compared with prior art, beneficial effects of the present invention are：Due to
The presence of extension spring, extension spring carries out energy-absorbing and flexible connection cast iron tup by the elongation of itself, so that cable
Vibrations effectively mitigate rocking for cable with being closed in the vibrations phase of cast iron tup；Simultaneously because the presence of draw ring, when cable is rocked
During 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 draw ring, so as to have
Effect ground mitigates rocking for cable, protects extension spring, prevents it from damaging.The device can be used as stockbridge damper, and it uses safety
Reliably.
It is connected for the ease of draw ring and extension spring with cable, is set with the upside of the cast iron tup on corresponding cable
Connecting tube for connecting extension spring and draw ring.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the close-up schematic view at A in Fig. 1.
Wherein, 1 short steel strand wires, 2 cast iron tups, 3 clamps, 4 extension springs, 401 draw rings, 5 cables, 501 connecting tubes.
Embodiment
As shown in Figure 1-2, a kind of stockbridge damper, including the cast iron tup 2 that one short steel strand wires 1 and its two ends are connected, short
Clamp 3 is connected with steel strand wires 1, the end of two cast iron tups 2 is connected with extension spring 4, the other end and the electricity of extension spring 4
Cable 5 is connected, and the inside of extension spring 4 is provided with the two oval draw rings 401 linked together, the two ends of draw ring 401 respectively with
Cable 5 is fixedly connected with cast iron tup 2, is connected for the ease of draw ring 401 and extension spring 4 with cable 5, on cast iron tup 2
The connecting tube 501 for connecting extension spring 4 and draw ring 401 is set with the corresponding cable 5 in side.
During work, first clamp 3 is fixedly connected on cable 5, while being fixedly connected with pipe 501 on cable 5, then will
Draw ring 401 is pierced into extension spring 4, and one end of draw ring 401 and extension spring 4 is fixedly connected on cast iron tup 2, finally will
Draw ring 401 and the other end of extension spring 4 are fixedly connected in connecting tube 501, when cable 5 has slight vibrations, stretching
Spring 4 extends while energy-absorbing, drives cast iron tup 2 to rock, so as to effectively mitigate rocking for cable 5, when cable 5 is violent
When rocking, the elongation of extension spring 4 is while energy-absorbing, reduces rocking for cable 5, when extension spring 4 reaches maximal tensility, draw ring
401 tense, and make cable 5 become to be rigidly connected with cast iron tup 2, are drawn so as to effectively mitigate being protected while rocking for cable 5
Spring 4 is stretched, prevents it from damaging.
The invention is not limited in above-described embodiment, on the basis of technical scheme disclosed by the invention, the skill of this area
Art personnel are according to disclosed technology contents, it is not necessary to which performing creative labour just can make one to some of which technical characteristic
A little to replace and deform, these are replaced and deformed within the scope of the present invention.
