Specific embodiment
The embodiment of the present invention is described in further detail below in conjunction with attached drawing.
Embodiment 1
Shown in Figure 1, the embodiment of the present invention provides a kind of impact energy consumption damper, including fixed device 1, fixed device
1 includes the first collet 10 and the second collet 11, and the first collet 10 is set to one end of fixed device 1, and the second collet 11, which is set to, to be fixed
The other end the first collet 10 and the second collet 11 of device 1 include fixed section and chuck end, wherein the first collet 10 and second
The fixed section of collet 11 is connected with fixed device 1, and the first collet 10 is then fixed on vibration source as transmitted electricity for that will fix device 1
On line, bridge cable etc., steel strand wires 2 are fixed in the chuck end of the second collet 11, steel strand wires 2 have certain length, and steel twists
The both ends of line 2 are stretched out from the both ends of the second collet 11 respectively.Steel strand wires 2 are constituted by more steel wires are twisted, when vibration source shakes
When dynamic, due to vibrating the heat production that rubs can occur for more steel wires on steel strand wires 2, convert thermal energy for vibration, successively reduce vibration.
It is shown in Figure 1, two tups 3 are further respectively had at the both ends of steel strand wires 2, each tup 3 is cavity structure,
And the inner surface of cavity is arc, is equipped with damping particles 30 in the cavity of each tup 3, damping particles 30 can in arc with
Meaning is swung.When damper is used to slow down the vibration of power transmission line or bridge cable, damping particles 30 can be according to power transmission line or bridge
The swing that any direction of vibration of cable generates respective direction is not limited to play the role of passive energy dissipation by direction, is subtracted
Effect of shaking is good.Fig. 1 is the schematic diagram that damper is set on power transmission line, since power transmission line is typically all laterally setting, vibrationproof
The whole also laterally setting of hammer；Fig. 2 is schematic diagram when damper is set on bridge cable, since bridge cable generally is vertical
Setting, therefore, damper are whole also vertically arranged.Since the cavity of damper is the structure that inner surface is arc, no
It is limited, is applied when on different vibration sources by the position of damper, damping particles 30 can be swung in cavity, play impact
The effect of energy consumption.
Further, the first collet 10 uses detachable connection with fixed device 1, can make to install not on fixed device 1
It, can be according to the actual size of vibration source when damper is used on different vibration sources with the first collet 10 of size
And the first collet 10 of corresponding size is selected, and guarantee being connected firmly for damper and vibration source to greatest extent, it will not be because of even
The use and performance for loosely influencing damper itself are connect, applicability is wide, practical.
Further, the first collet 10 includes first clamping piece and second intermediate plate, a side and second intermediate plate of first clamping piece
A side it is hinged, another side of another side and second intermediate plate fastens, the hinged flexible part in one side of the first collet 10, energy
Guarantee that first clamping piece and second intermediate plate are opened or are closed around hinge side under certain dynamics.It is equipped on the first collet 10 tight
Firmware, fastener are used to reinforce the fastening of first clamping piece and second intermediate plate, can reinforce the clamping of the first collet 10, avoid because using
Occur the first collet 10 after time is long or material itself expands with heat and contract with cold and the problem of connection loosens occurs with vibration source.
Referring to shown in Fig. 1-Fig. 2, it is contemplated that damping particles 30 consume one and swinging in the arc-shaped cavity in tup 3
Point vibrational energy, therefore here tup 3 it is preferably spherical, the preferably spherical cavity of the cavity of tup 3 makes damping particles 30 can
Preferably to be swung in cavity, to weaken consumption vibration.Secondly, damping fluid 31 can be added in the cavity of tup 3, work as vibration
Source Oscillation Amplitude is larger, only by damping particles 30 cannot well vibration damping when, in spherical hollow space be added damping fluid 31,
The addition of damping fluid 31 can increase the quality of tup 3 first, secondly when vibration source vibration when, damping fluid 31 with vibration side
It is fluctuated to towards corresponding direction.Damping fluid 31 can may be other liquid for distilled water, due to consideration that damper is general
With outdoors, temperature change is larger, and therefore, damping fluid 31 is preferably silicone oil, and silicone oil condensation point is low, and boiling point is high, and thermal stability is good,
It is suitble to open air use.
Further, the quantity of damping particles 30 can be one, and the quantity of damping particles 30 may be at least two,
And damping particles 30 are spherical shape.When the vibration of vibration source is smaller, the number of damping particles 30 is one, 3 lighter weight of tup,
When the vibration of vibration source is larger, the quantity of damping particles 30 is multiple, 3 heavier mass of tup, and anti-vibration effect can be preferable.
Embodiment 2
A kind of impact energy consumption damper is present embodiments provided, is with the difference of above-described embodiment: the two of steel strand wires 2
Rotation is set there are two tup 3 respectively at end, and each tup 3 is all made of cavity structure, and the side of cavity is arcwall face, each tup
Damping particles 30 are equipped in 3 cavity.When damper use is on different vibration sources, since the direction of vibration source is not true
It is fixed, and the needs of damping particles 30 are swung on the face of arc, therefore two tups 3 are rotatably dispose in the both ends of steel strand wires 2, are such as schemed
Shown in 3, when use is on power transmission line, two 3 left and right settings of tup, as shown in figure 4, when use is on bridge cable, two
A tup 3 is in setting up and down, but arcwall face is always positioned at lower section, guarantees that damping particles 30 can freely swing, reaches best
Anti-vibration effect.Cavity is more succinct using the manufacturing process for the tup 3 that the design of one side makes, and cost is lower.
Specifically, each tup 3 is connected by Universal rotary connector with one end of steel strand wires 2, and in each Universal rotary
Finite place piece is all provided on adapter, locating part is used to limit the relative rotation between tup 3 and steel strand wires 2.In use,
According to the orientation of the direction of vibration source and the first collet 10 damper after fixed, the orientation of tup 3 is adjusted, arcwall face is located at
Lower section guarantees that damping particles 30 are swung in arcwall face, and the orientation of damper will not be made different and influence the performance of damper and just
It is often used.
The present invention is not only limited to above-mentioned preferred forms, anyone can show that other are each under the inspiration of the present invention
The product of kind form, however, make any variation in its shape or structure, it is all with identical or similar with the present invention
Technical solution, within its protection scope.
