Description
Technical field
The utility model relates to a kind of damper, especially a kind of damper for overhead transmission line belongs to electric power
Equipment technical field.
Background technique
High-tension overhead line bar position is higher, and span is larger, when conducting wire is acted on by wind-force, it may occur that vibration, due to more
Steel strand wires damper is widely used in the prior art and comes to frame because fatigue rupture can occur for periodically bending for secondary vibration, conducting wire
The vibration of ceases to be busy cable is controlled, when cable vibrates so that connector vibrates, under the action of tup inertia force, and steel strand wires hair
Raw bending deformation, can generate with the movement of conductor vibration opposite in phase, to make conductor vibration elimination or decrease.But it is common at present
Damper when becoming bent deformation displacement it is smaller, cause to damp small, damper mass motion amplitude is big, causes to vibrate cable
Control effect is bad.
Summary of the invention
The purpose of this utility model is that: a kind of damper for overhead transmission line is provided, current damper is overcome
Mass motion amplitude is big, small to absorption of vibrations, the bad phenomenon of anti-vibration effect.
In order to achieve the above object, the technical solution adopted in the utility model are as follows: a kind of vibrationproof for overhead transmission line
Hammer, including connector and tup, connector lower section are fixedly connected with hammerhead jib, and hammerhead jib both ends are connected with tup, and the connector is used
It is connected in same cable, the tup is elliposoidal tup, and the long axis of elliposoidal tup is in a horizontal position, and the tup is hollow to be set
It sets, is provided with billiards in the hollow cavity in tup；The hammerhead jib is elasticity hammerhead jib made of elastic material, is surround on elastic hammerhead jib
There is spring, the spring one end is fixedly connected with connector, and the spring other end is fixedly connected with tup；Further, described anti-
The hollow cavity wall of vibration hammer is covered with elastomeric layer；Further, horizontal threading hole, cable are provided on the connector
It is connect by threading hole with connector, two spacing between tup and connector are equal；Further, the connector includes
Clamp and connecting plate, the threading hole are threaded through on clamp, and clamp lower end is connect with connecting plate, the lower end of connecting plate with
Hammerhead jib connection.
The positive advantageous effects of the utility model are: intracavitary by the way that elliposoidal hollow cavity is arranged on damper
Billiards is set, and billiards is located near sites among hollow cavity when calm, and when damper wind-engaging moves, billiards is past in hollow cavity
It is multiple to move and collided with hollow cavity wall, big energy is consumed, and due to elliposoidal hollow cavity both ends height, billiards has back
The trend of multiple center, the motion frequency of billiards is more straight, and space is higher, more preferably for low-frequency vibration vibrationproof performance, Er Qiexiang
More solid damper overcomes the inertia effects of solid damper, and inhibition of vibration is better than the solid damper of equivalent weight, in
The collision energy of billiards can be absorbed in the flexible material layer being arranged in cavity, enhances inhibition of vibration, elastic hammerhead jib and elastic hammerhead jib
Upper circular spring can be absorbed energy when cable moves up and down, further increase inhibition of vibration.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Fig. 2 is the structural schematic diagram of the utility model one embodiment tup.
Specific embodiment
In order to more fully explain the implementation of the utility model, the embodiment of the utility model presented below, these realities
Applying example is only the elaboration to the utility model, does not limit the scope of the utility model.
It is attached in the figure, it is marked as 1. clamps in conjunction with attached drawing to the further details of explanation of the utility model；2. threading
Hole；3. connecting plate；4. tup；5. hammerhead jib；6. billiards；7. spring；8. flexible material layer.
It is as shown in the figure: a kind of damper for overhead transmission line, including the company being made of clamp 1 and connecting plate 3
Fitting and tup 4, clamp lower end are connect with connecting plate, and threading hole 2 is provided on clamp, is fixedly connected with below connecting plate
Hammerhead jib 5, hammerhead jib both ends are connected with tup 4, and two spacing between tup and connector are equal, and tup is elliposoidal tup, ellipse
The long axis of spherical tup is in a horizontal position, the hollow setting of tup, is provided with billiards 6 in the hollow cavity in tup；Hammerhead jib is bullet
Elasticity hammerhead jib made of property material, elastic material can be the wirerope of rubber bar or hinge joint or include the rubber that wirerope is skeleton
Glue stick is surrounded with spring 7 on elastic hammerhead jib, and spring one end is fixedly connected with connecting plate, and the spring other end is fixedly connected with tup,
The hollow cavity wall of damper is covered with elastomeric layer, and elastomeric layer can be emulsion layer, rubber layer or flexible ABS plastic
Layer.
The utility model on damper by being arranged elliposoidal hollow cavity, and intracavitary setting billiards, billiards is located at when calm
Near sites among hollow cavity, when damper wind-engaging moves, billiards moves back and forth in hollow cavity and with hollow cavity wall
Collision consumes big energy, and due to elliposoidal hollow cavity both ends height, billiards has the trend for replying center, billiards
The more straight space of motion frequency it is higher, more preferably for low-frequency vibration vibrationproof performance, and compare more solid damper, overcome
The inertia effects of solid damper, inhibition of vibration are better than the solid damper of equivalent weight, the flexible material being arranged in hollow cavity
Layer, can be absorbed the collision energy of billiards, enhance inhibition of vibration, and circular spring, can inhale on elastic hammerhead jib and elastic hammerhead jib
Energy when take-up cable moves up and down, further increases inhibition of vibration.
After the embodiments of the present invention is described in detail, one of ordinary skilled in the art is clearly understood that,
Various change and modification can be carried out by not departing under above-mentioned claim and spirit, all according to the technical essence of the utility model
Any simple modification, equivalent change and modification to the above embodiments belong to the range of technical solutions of the utility model,
And the utility model is also not only restricted to the embodiment of example in specification.
