Description
Technical field
The present invention relates to a kind of damper, specifically a kind of external stayed cable closed cylinder type sticky shearing type damping
Device, belongs to suspension cable damper technique field.
Background technology
With continuing to develop for modern bridging technology, bridge span structure develops towards tall and big, soft, low resistance trend development
Overlength, Long span Flexible bridge are a kind of international trend.The cable-stayed bridge span built in recent years both at home and abroad increasingly increases, and draws
Rope also increasingly increases.Suspension cable is one of main supporting member of cable-stayed bridge, because suspension cable quality is small, flexibility big, internal damping
Low reason produces vibration easily under extraneous environmental excitation.Lasting inhaul cable vibration can cause the tired and anti-of drag-line and anchor head
The destruction of sheath, shortens the service life of drag-line, adds the maintenance and repair expense of bridge, can also make pedestrian to cable-stayed bridge
Security throws doubt upon.Therefore, it is essential to suppress Inclined Cable Vibration, and existing suspension cable damped products have a lot.
There is following deficiency in existing drag-line external damper：
1. existing drag-line mounted-out viscous shearing dampener is generally unenclosed construction, only anti-by dust cover and rubber
Dirt plate can not completely completely cut off with outside air, and extraneous dust and steam etc. can still be invaded, and can influence the performance of damper and use
Life-span.
2. existing drag-line mounted-out viscous shearing dampener casing welds rectangularity by steel plate more, appearance and size compared with
Greatly, sole mass is heavier, installs and safeguard quite inconvenient.And because damper up-down structure is without positioning and guiding measure, damp up and down
Device casing is free state, causes damper casing location difficulty, there is jam phenomenon after installation.
3. during the larger suspension cable of existing drag-line mounted-out viscous shearing dampener angle in for face（≥
45°）, because damper casing installation requirement is vertical with drag-line, cause damper casing angle of inclination excessive, i.e., with horizontal plane
Angle is too small, damper box house high viscosity resisting medium can produce it is excessive, to avoid excessive to change damper casing
Installation approach, decrease damper damping performance, outward appearance can not also be unified.
4. existing drag-line external sticky shearing damper up-down structure is only connected by resisting medium, unlimited bit architecture,
The off-center position of damper is easily caused in transport and installation process, the installation of damper is influenceed.
It is installed on 5. existing drag-line external sticky shearing damper is single pattern in drag-line face, due to internally-damped
Active position from drag-line farther out, the outer turning effect in damper generation face can be made when drag-line out-of-plane vibration, damper is reduced
Effectiveness in vibration suppression outside face.
6. existing drag-line external is viscous（Oil）Damper and similar products are by end cap, cylinder barrel, piston rod, piston group
Into closed structure, the full silicone oil of inside filling.When external world's motion drives piston rod movement, by extruding internal silicone oil, make silicone oil
Power consumption effect is produced by the aperture on piston, the purpose of vibration damping is reached.During such damper work, due to pressing for silicone oil
Contracting is smaller, and cylinder interior must produce higher pressure, it is ensured that silicone oil is not leaked, and all parts will ensure higher processing
And assembly precision, piston rod surface can not have any scratch, pit, and its surface smoothness requirements is also very high, and sealing ring
Sealing property and service life directly affect the service life of damper.
The content of the invention
It is an object of the present invention to overcome the above deficiencies, so as to provide a kind of external stayed cable closed cylinder type viscosity
Shearing type damper, damping cavity is closed structure, is vertically connected with filled high polymer viscosity resistance between part band guide and limit, internal prongs
Buddhist nun's liquid, damping fluid is difficult leakage, service life length, installation and transportation are convenient, install and use not tension cable setting angle influence, damping
There is self-locating function in device, will not be shifted with installing hole distance in installation process in carrying, improve damper and effect is installed
Rate.

The magnetic links magnetic of setting is opposite.
Further, interpolation pipe can use single tube structure or multipipe structure.
Further, ears ring includes being provided with gap between two symmetrically arranged otic placodes, otic placode, and otic placode is provided with logical
Hole, the end face of ears ring is provided with screwed hole, for being connected with guide rod termination.
Further, external damping cylinder lower end, which is provided with monaural ring, monaural ring, is provided with oscillating bearing.
Further, guide rod and ears ring junction are provided with dust cover, and dust cover is by external damping cylinder upper end and guide cover
Including cover holds together.
Compared with the prior art the present invention has advantages below：
1. the present invention is simple in construction, compact, reasonable, good appearance, dependable performance, external environment strong applicability, manufacture add
Work and maintenance cost relative moderate, maintenance, replacing convenience, good market prospect；
2. by the intermolecular internal friction of macromolecule viscous damping liquid filled between interpolation pipe and damping cylinder, it will move
Energy be converted into thermal dissipation and go out, so as to play damping effect；Pass through the adjustable resistance of the change of the viscosity or amount of damping fluid
The size of Buddhist nun's power, it is simple to operate to adapt to the drag-line of different size；
3. damping fluid is enclosed in damping cylinder, it will not be influenceed by external environment and lose its function, also can be in applicable surface
The larger suspension cable of angle is installed；
4. because the guide cover of damper is damped inside cylinder without producing higher pressure, and only interpolation pipe upward, during work
With damping cylinder intersection filling damping fluid, its complementary space undamped liquid, therefore, even if damper install after seal damage or
Damping fluid leakage will not also occur for guide rod abrasion, and damper remains to normal work；
5. being provided with magnet steel in damper, with self-locating function, will not occur with installing hole distance in installation process in carrying
Skew, improves damper installation effectiveness；
6. can two dampers composition triangles install and use, the face that can effectively reduce drag-line inside and outside vibrates；
7. two ends earrings is attached with suspension cable for articulated manner, the small size deviation of drag-line angle is adapted to, it is to avoid resistance
Stuck, the influence damper normal work of Buddhist nun's device.
