Portion's vibration is larger, and the serious vibration of tower influences the service life of tower, it is therefore desirable to which a kind of new technical solution solves
State problem.
Utility model content
For the vibration for weakening tower top, the utility model is mounted with a kind of resistance suitable for tower top section in tower top
Buddhist nun's device changes mesomerism characteristic, to reach cushioning effect.
The technical solution adopted in the utility model is as follows: a kind of damping unit suitable for tower top section, including main body, resistance
Buddhist nun's bar and frequency modulation device, the main body include the swing arm set gradually using support rod as axle center, block of improving quality, check device and under
Mass block, the swing arm are hinged on the end of support rod, and the check device is connected with block of improving quality, the tail of the lower mass block
Portion is set to the bottom end of support rod, and the frequency modulation device, damper rod are each attached to support rod bottom, if the damper rod is provided with
Dry, several described damper rods are uniformly arranged at an angle in the surrounding of frequency modulation device.
Further, there are three the damper rod is arranged altogether.
Further, frequency modulation spring is provided in the frequency modulation device, the vibration frequency of the frequency modulation spring stretches setting
At close with main body frequency.
Further, it is mutually fixed between each damper rod and the tail portion of support rod by connecting rod.
Further, the height phase of distance of the check device to lower mass block and the non-return ring positioned at tower top section
Deng.
The utility model has the beneficial effects that the vibration damping to pylon is realized by the main system kinetic characteristics for changing pylon,
Increase the service life of tower；Structure and principle are simple, are easy to use.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to the protection scope of the utility model.
As shown in Figure 1, 2, damping unit includes main body, damper rod 6 and frequency modulation device 7, and main body includes with support rod 5 for axis
Swing arm 1, block 2 of improving quality, check device 3 and lower mass block 4, the swing arm 1 that the heart is set gradually are hinged on the end of support rod 5, only
3 top of return device is fixedly connected with the bottom end for block 2 of improving quality, and the tail portion of lower mass block 4 is set to the bottom end of support rod 5, frequency modulation
Device 7 and damper rod 6 are each attached to 5 lower end of support rod, and damper rod 6 is provided with several, several damper rods 6 are in frequency modulation device
7 surrounding is uniformly arranged at an angle.The present embodiment damper rod 6 is arranged three altogether, and three damper rods 6 are solid by connecting rod 8
Due to lower 4 tail portion of mass block, three damper rods 6 are uniformly arranged at an angle in the surrounding of frequency modulation device 7.In frequency modulation device 7
It is provided with frequency modulation spring, the vibration frequency stretching of frequency modulation spring is arranged to close with main body frequency.Check device 3 and lower mass block
The distance between 4 be arranged to be located at the height of non-return ring 11 of tower top section it is equal.
After damping unit is installed on tower top section, top swing arm 1 is connect with tower top section hanging beam 9, and 9 lower end of hanging beam is supported in
In the support of 10 hanging beams, non-return ring 11 is installed between check device 3 and lower mass block 4, entire damping unit is made with 11 phase of non-return ring
With lower end and 12 phase of frequency modulation platform of entire damping unit are fixed, and frequency modulation platform 12 is supported in frequency modulation support 13.Frequency modulation platform
12 for fixing the frequency modulation device 7 of damping unit, and 7 lower end of frequency modulation device is fixed by bolt 14, and bolt is by frequency modulation device 7 and adjusts
After frequency platform 12 is fixed, it is special to change mesomerism to near the vibration frequency of damping unit top end main body for drawing spring elongation
Property, three damper rods 6 of damping unit bottom end, when damping unit is swung with tower, to swaying direction one anti-work of tower
Firmly, the amplitude of tower is reduced, to play the role of damping.To sum up, band dynamic damping fills when tower operation generates vibration
It sets and vibrates together, damping unit movement generates inertia force and reacts on tower, and coordinates this inertia force, and damping unit movement produces
Raw inertia force vibrates contrary with cylinder, greatly reduces cylinder amplitude.
