Abstract
The present invention relates to power communication facility fields, particularly disclose swing damping device at the top of a kind of single-pipe tower, it includes single-pipe tower, it is characterized in that：A circle damping partition board is equipped in the single-pipe tower inside top by rope suspensions pendular body, around the pendular body, is the supporting plate for holding damping partition board below the damping partition board, the supporting plate is fixed in single-pipe tower tower wall；It is equipped between the damping partition board and single-pipe tower tower wall in the uniformly distributed spring of radioactivity.Under wind load or seismic loading, iron tower horizontal displacement can be reduced；When amplitude of fluctuation is larger, pendulum column is hit in damping system, can avoid direct collision to the side wall of single-pipe tower, and spring and pendulum the column power that move direction to single-pipe tower generation one together opposite, so as to achieve the effect that reduction displacement.
Description
Technical field
The present invention relates to power communication facility field, swing damping device at the top of more particularly to a kind of single-pipe tower.
Background technology
Single-pipe tower is mainly used as power transmission tower and communication tower, belongs to tall and slender structure.Under wind load and seismic loading, tower
It is larger to push up horizontal displacement.For the angle for using function, there is following defect：When as power transmission tower, larger horizontal displacement
May be pulled off the power transmission line connected thereon；When as communication tower, larger horizontal displacement may make the day placed thereon
Line and signal device are got rid of and are fallen, this can all lead to the failure of transmission system and communication system；
Patent of invention " novel single tube tower "（CN 205189482 U）It proposes to put a steel ball as damper in tower top, but it is logical
Normal tower roof of single-tube tower caliber all very little, common top calibers have 400mm, 600mm etc..If the too small light weight of steel ball is not achieved
Damping effect is easy for greatly very much colliding so as to cause its destruction with single tube tower wall in vibration processes, and this way is very
It is difficult really to realize damping effect.
Invention content
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of reduction horizontal displacement, ensure single-pipe tower safety
Swing damping device at the top of single-pipe tower.
The present invention is achieved through the following technical solutions：
Swing damping device at the top of a kind of single-pipe tower, including single-pipe tower, it is characterized in that：Pass through in the single-pipe tower inside top
Rope suspensions pendular body is equipped with a circle damping partition board around the pendular body, is for holding damping below the damping partition board
The supporting plate of partition board, the supporting plate are fixed in single-pipe tower tower wall；It is equipped between the damping partition board and single-pipe tower tower wall in radiation
The uniformly distributed spring of property.
The damping partition board is with rigid hard board partition.
The damping partition board is made of several demarcation strips, has partitioning slot between adjacent two pieces of demarcation strips.
The spring shares two circle up and down.
There are four springs between every piece of demarcation strip and single-pipe tower tower wall.
The pendular body is cylinder.
The beneficial effects of the invention are as follows：
Under wind load or seismic loading, iron tower horizontal displacement can be reduced；When amplitude of fluctuation is larger, pendulum column is hit
In damping system, direct collision can be avoided to the side wall of single-pipe tower, and spring and pendulum column generate one to single-pipe tower together
The opposite power in direction is moved, so as to achieve the effect that reduce displacement.
Description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the schematic cross-sectional view of the present invention；
Fig. 2 be Fig. 1 in A-A to cross section structure schematic diagram.
In figure, 1 single-pipe tower, 2 supporting plates, 3 demarcation strips, 4 springs, 5 partitioning slots, 6 ropes, 7 pendular bodies, 8 lightning rods.
Specific embodiment
Attached drawing is specific embodiments of the present invention.As shown in Figure 1, 2, swing damping device at the top of this kind of single-pipe tower, packet
Single-pipe tower 1 is included, lightning rod 8 is installed in its tower top, the good rope of a tensile property is anchored at 1 inside top center of single-pipe tower
6,6 lower end of rope connects a pendular body 7, and pendular body 7 can be a ball, it is preferred that cylinder, if because ball
Too small, then because of light weight, damping effect unobvious if too big, are limited by tower top space, amplitude of fluctuation compared with
It is small, and the pendular body 7 of cylindrical shape can be carried in the case where the cross-sectional area of cylinder is certain by increasing its height
Its high quality, so as to increase damping effect；One block of annular supporting plate 2, support are welded in 1 tower wall of single-pipe tower around pendular body 7
Damping partition board is placed on plate 2, supporting plate 2 holds damping partition board, and damping partition board can move on supporting plate 2, and damping partition board is preferably
Hard board partition with certain rigidity passes through the radially distributed bullet of upper and lower two circles between 1 tower wall of damping partition board and single-pipe tower
Spring 4 connects, and 4 one end of spring is welded in 1 tower wall of single-pipe tower, and the other end is anchored on damping partition board, when pendular body 7 is swung,
By pendular body 7 be transmitted through Lai power can equably be transmitted to spring 4 below, and the damping of this fibrous material with rigidity every
Plate is not easy to be broken by pendular body 7, in stationary state, has a certain distance between pendular body 7 and damping partition board, convenient for swinging
Body 7 has certain amplitude of fluctuation；When damping partition board is an entirety, if when pendular body 7 bumps against one side and rum point is opposite
The another side answered can also follow equidirectional movement, and the spring 4 at this moment connected behind is possible to and the anchor point quilt of damping partition board
Failure is drawn, therefore damping partition board is preferably made of several demarcation strips 3, there are partitioning slot 5, every piece of separations between adjacent separator plates 3
It is connected between 1 tower wall of plate 3 and single-pipe tower by four springs 4, each two up and down.When pendular body 7 is bumped against on damping partition board, one
Aspect spring 4 can play cushioning effect, avoid pendular body 7 that 1 tower wall of single-pipe tower is broken, another aspect pendular body 7 makes spring 4
Compressive deformation, at this time spring 4 just produce a power opposite with 1 direction of motion of single-pipe tower, reach reduce deformation damping effect
Fruit.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
