End, steel pipe body interior are hung with damping piece by connecting rope, and elastic component, elasticity are equipped between damping piece and steel pipe main body inner wall
Part one end is connected with damping piece, and the other end is connected with steel pipe main body inner wall.
Here is the further optimization and/or improvements to above-mentioned utility model technical solution:
Above-mentioned elastic component can be to be multiple, and all elastic components are provided at circumferentially spaced along steel pipe main body.
Above-mentioned steel pipe main body may include at least one the steel pipe monomer for being fixedly connected sequentially and being connected to from the bottom to top, Mei Gegang
Damping piece is equipped with inside pipe monomer, all damping pieces pass sequentially through connecting rope connection, the damping piece of the top from the bottom to top
It is connected to by connecting rope on the roof of steel pipe body interior.
Above-mentioned each intracorporal damping piece of steel pipe list may be provided at 1/2 to 3/4 place of the steel pipe monomer height.
Above-mentioned damping piece can be metal heavy ball.
The utility model reasonable and compact in structure, it is easy to use, by the damping piece of setting suspension, and in damping piece and
Elastic component is connected between the inner wall of steel pipe main body, so as to generate a large amount of damping when wind-induced vibration occurs for whole device,
The loss for accelerating vibrational energy extends service life to reach good damping.
Detailed description of the invention
Attached drawing 1 is the main view broken section structural schematic diagram of the best embodiment of the utility model.
Coding in attached drawing is respectively as follows: 1 for lightning rod needle point, and 2 be connecting rope, and 3 be damping piece, and 4 be elastic component, and 5 be steel
Pipe monomer.
Specific embodiment
The utility model is not limited by following embodiments, can technical solution according to the present utility model and actual conditions
Determine specific embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to specification
The Butut mode of attached drawing 1 is described, such as: front, rear, top, and bottom, left and right positional relationship be according to Figure of description
Butut direction determine.
The utility model is further described below with reference to examples and drawings:
As shown in Fig. 1, only pole type lightning protection needle of the subsidiary damping unit includes steel pipe main body and lightning rod needle point 1, steel
Pipe main body is hollow tube, and lightning rod needle point 1 is mounted on steel pipe main body upper end, and steel pipe body interior is hung with by connecting rope 2
Damping piece 3 is equipped with elastic component 4 between damping piece 3 and steel pipe main body inner wall, 4 one end of elastic component and damping piece 3 connect, the other end
It is connected with steel pipe main body inner wall.As needed, lightning rod needle point 1 is fixedly mounted on the upper end of steel pipe main body, steel pipe by flange
The lower end of main body is fixedly mounted on pedestal by flange, and 2 upper end of connecting rope is fixedly connected on the roof of steel pipe body interior,
So that damping piece 3 can be suspended on steel pipe body interior, elastic component 4 is compressed spring, and under normal condition, compressed spring is kept
Original is long, and when steel pipe main body is generated vibration by wind load, the damping piece 3 of steel pipe body interior suspension can also be swung, into
And a large amount of damping is produced, in addition damping piece 3 can also constantly compress or draw springs 4 during the swing, will damp
Part 3 can overcome the elastic potential energy of elastic component 4 to do work during the swing, so that the loss of vibrational energy is increased, so that entirely
The wind-induced vibration energy of device quickly declines, i.e., can be shaken to the charming appearance and behaviour of whole device by the setting of damping piece 3 and elastic component 4
It is dynamic to play good damping, the vibrating fatigue of flange connections bolt is reduced, service life is extended.
Above-mentioned only pole type lightning protection needle can be made further optimization and/or improvements according to actual needs:
As shown in Fig. 1, steel pipe main body inner wall is circumferentially intervally distributed with multiple elastic components 4.As needed, elastic component 4
It can be in for 4 and sustained height, 4 elastic components 4 are uniformly arranged along the circumferencial direction interval of steel pipe main body inner wall, 4 bullets
The setting of property part 4 has further speeded up the loss of vibrational energy, improves damping.
As shown in Fig. 1, the steel pipe main body include be fixedly connected sequentially from the bottom to top and inner cavity connection at least one
Steel pipe monomer 5 is equipped with damping piece 3 inside each steel pipe monomer 5, and all damping pieces 3 pass sequentially through connecting rope 2 from the bottom to top
The damping piece 3 of connection, the top is connected on the roof of steel pipe body interior by connecting rope 2.According to demand, steel pipe main body packet
It includes 3 steel pipe monomers, 5,3 steel pipe monomers 5 and passes sequentially through flange from the bottom to top and be fixedly installed togather, in each steel pipe monomer 5
It is equipped with a damping piece 3, to can guarantee that each steel pipe monomer 5 shakes in charming appearance and behaviour by the setting of damping piece 3 and elastic component 4
By biggish damping action when dynamic, to reduce the vibrating fatigue of each 5 upper flange junction bolt of steel pipe monomer, prolong
The service life for having grown steel pipe main body passes sequentially through connecting rope 2 additionally, due to all damping pieces 3 from the bottom to top and connects, more often
A damping piece 3 is connected to for steel pipe body interior determines wall separately through connecting rope 2, and the damping piece 3 in the utility model is put
Dynamic amplitude can be bigger, i.e., it is bigger to swing the damping generated by damping piece 3, further improves damping.
As shown in Fig. 1, the damping piece 3 in each steel pipe monomer 5 is arranged in the 1/2 to 3/4 of 5 height of steel pipe monomer
Place.As needed, the damping piece 3 in each steel pipe monomer 5 is arranged at the 2/3 of 5 height of steel pipe monomer, and damping piece 3 is being put
The damping generated when dynamic is maximum.
As shown in Fig. 1, the damping piece 3 is metal heavy ball.Metal heavy ball quality small in size is big, at low cost, is swinging
When the damping that generates it is big.
The above technical characteristic constitutes the most preferred embodiment of the utility model, with stronger adaptability and best implementation
Effect can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
