Description
Technical field
The utility model is related to stockbridge damper, specifically a kind of damper using viscous damping vibration suppression.
Background technology
Under normal conditions, wire can influence the performance of transmission pressure at every moment all in the state of vibration when serious
Or cause fatigue stranded, cause economic loss.Many amplitudes that vibration is reduced using damper in Practical Project.But it is existing
Solid hammer formula being used some dampers, using tup vibration and steel strand wires stock and the friction energy-dissipating of stock, form is single more, it is impossible to
The architectural characteristic of itself is made full use of, and effect is less desirable.And by the engineering of some built long-span electric transmission lines
Under case and field experiment it was found that vibrate for a long time, the junction of fixing clamper and vibrationproof tup and steel strand wires
Easily there is the situation of sliding and serious wear, this is greatly lowered the vibration suppression performance of damper, the life-span of shadow transmission pressure,
The serious gold utensil for also needing to more renew, expends substantial amounts of manpower and materials.
Utility model content
It is suitable that vibrationproof tup is set to filling in cavity structure, cavity structure by the utility model on the basis of existing damper
The cement liquid of amount, restricting orifice is provided with the intermediate lateral of cavity structure, and cement liquid can be cut by restricting orifice
Viscous force is cut to reach the purpose of passive energy dissipation.
In order to solve the above-mentioned technical problem, the utility model proposes following technical scheme：One kind can be pressed down using viscous damping
The damper for shaking, it includes vibrationproof tup, and the vibrationproof tup is provided with clamp sleeve, the pressure with steel strand wires end junction
Tight sleeve pipe uses three valve split type structures, and it includes cylindrical end and conical end, and the cylindrical end is embedded in the connection of vibrationproof tup
Inside hole, the conical end outer cover is equipped with adjusting nut.
The position that the steel strand wires are contacted with fixing clamper is also provided with clamp sleeve, the cylindrical end edge of the clamp sleeve
It is embedded in inside the connecting hole of fixing clamper, the conical end outer cover is equipped with adjusting nut.
The vibrationproof tup uses cavity structure, and restricting orifice and cement liquid are placed with cavity inside.
The inside of the clamp sleeve is inlaid with one layer of rubber.
The utility model has the advantages that：
This patent can particularly produce the principle of throttle resistance and be made when fluid is by throttle orifice according to fluid motion
, and there is the clamp sleeve of fixed use the junction of steel strand wires and gold utensil to carry out second consolidation, can increase wire clamp with steel strand
The contact area of line, prevents the sliding of steel strand wires.Rubber blanket is provided with clamp sleeve, can protect steel strand wires at sleeve pipe from
Abrasion.The damper new in structure, it is cheap, it is possible to achieve the purpose of power consumption vibrationproof, and steel strand wires can be prevented
Sliding, can provide a kind of new mentality of designing for the developmental research of vibrationproof gold utensil.

The end junction of steel strand wires 4 is provided with clamp sleeve 6, the clamp sleeve 6 uses three valve split type structures, and it includes cylinder
End and conical end, the cylindrical end are embedded in inside the connecting hole of vibrationproof tup 1, and the conical end outer cover is equipped with adjusting nut
7。
Further, the position that the steel strand wires 4 are contacted with fixing clamper 5 is also provided with clamp sleeve 6, the clamping sleeve
The cylindrical end of pipe 6 is embedded in inside the connecting hole of fixing clamper 5, and the conical end outer cover is equipped with adjusting nut 7.
Further, the vibrationproof tup 1 uses cavity structure, and restricting orifice 3 and slilme are placed with cavity inside
Body 2.
Further, the inside of the clamp sleeve 6 is inlaid with one layer of rubber.
The course of work of the present utility model and operation principle are：
A kind of damper using viscous damping vibration suppression, when aeolian vibration, conductor vibration, the vibrationproof installed on wire
Hammer can vibrate therewith, will be by restricting orifice, so as to produce a kind of shearing viscous when the viscous liquid in such cavity vibrates
Resistance suppresses vibration, and the friction between the vibration of tup and steel strand wires stock and stock can also dissipate a part of wind energy.
Be cased with clamp sleeve in the junction of steel strand wires and tup and wire clamp, the small one end of casing diameter put in wire clamp and
In tup, the other end is exposed to be enclosed within steel strand wires outside, and inner sleeve and the junction of outer sleeve have similar step-like convex
Rise, after outside sleeve pipe is bolted, bossing can just withstand wire clamp, tup, prevent sliding.And have rubber in sleeve pipe
Rubber cushion, to prevent the friction damage between gold utensil and steel strand wires.
By above-mentioned description, those skilled in the art completely can be without departing from this utility model technological thought
In the range of, carry out various changes and amendments all within protection domain of the present utility model.It is of the present utility model not most
Matters, belong to the common knowledge of those skilled in the art.
