Description
Technical field
The utility model relates to communicate ancillary equipment field, and in particular to a kind of three towers.
Background technique
The antenna holder of existing three tower is generally connected by screw bolts or is welded on king-post, using the connection of welding
Mode, antenna holder can not be dismantled, and antenna holder just is completed to weld with king-post before installing, and the installation accuracy of antenna holder depends on
The quality of welding, and the mode being connected by screw bolts, to make antenna holder and king-post be connected firmly, preventing antenna holder from deflecting,
Tightened using bolt and be easy to cause king-post surface damage, since wind load is larger when king-post uses, be easy from king-post it is impaired from
It bends.Therefore, need that a kind of installation accuracy is high, king-post surface is not easy due to installing three impaired towers.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of installation accuracy height, king-post table
Face is not easy due to installing three impaired towers.
The purpose of this utility model is implemented with the following technical solutions:
A kind of three towers, the king-post of the prism distribution including three corresponding triangular platforms several are used to connect adjacent two towers
The cross bar and antenna holder of column, antenna holder include columned platform, the first connecting rod of one end and platform side connection and company
It is connected to the pole of the first connecting rod other end, platform offers round table-like through-hole, and through-hole is coaxial with platform, and the inner wall of through-hole is equipped with
Three are less than π with the corresponding matched arc groove in king-post side, the radian of arc groove；Each king-post is equipped with upward for limiting platform
The barrier assembly of movement.
Preferably, barrier assembly is clip.
Further, it is connected between adjacent clip by second connecting rod.
Preferably, each first connecting rod other end is equipped with U-bolt, and each pole passes through corresponding U-bolt and corresponding first
Connecting rod connection.
Preferably, at least provided with two first connecting rods on the platform side of same perpendicular.
Preferably, the angle of each king-post and horizontal plane is 88 °~89 °.
Preferably, mounting plate is equipped at the top of king-post, mounting plate is equipped with lightning rod.
Compared with prior art, the utility model has the beneficial effects that:
It is entrenched in arc groove by the side of king-post, horizontal direction upper king-post strut can not be rotated relative to platform, as long as protecting
The side for demonstrate,proving king-post is fitted into place in arc groove, and high accuracy install can be realized；It is limited on vertical direction by barrier assembly
Platform moves upwards, and due to being obliquely installed for king-post, limits platform by the distance between each king-post and moves downward, relative to existing
The gravity of bolt long-time bearing platform when having technology to adopt reinforcing, platform is small to the active force of king-post in the utility model, and king-post is not
It is easily damaged；Three king-posts are in firm triangular structure under the connection of cross bar, and structural strength is high.

It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
As shown in Figure 1-3, as three towers in one of specific embodiment of the utility model, including three
King-post 10, several cross bars 20 and antenna holder for being used to connect adjacent two king-posts 10 of the prism distribution of corresponding triangular platform, day
Line bracket includes the first connecting rod 302 and be connected to first connecting rod that columned platform 301, one end and 301 side of platform connect
The pole 303 of 302 other ends, platform 301 offer round table-like through-hole 3011, and through-hole 3011 and platform 301 are coaxial, through-hole
3011 inner wall set there are three with the corresponding matched arc groove 3012 in 10 side of king-post, the radian of arc groove 3012 is less than π；Each tower
Column 10 is equipped with the barrier assembly moved upwards for limiting platform 301.
Three prisms of the corresponding triangular platform of three king-posts 10 of three towers, the distance between three king-posts 10 from top to bottom by
It is cumulative big, it is the routine techniques of those skilled in the art according to the size that through-hole 3011 is arranged in the actual installation height of platform 301
Means, details are not described herein, and after platform 301 is installed in place, lower end, can not be downward since the distance between three king-posts 10 increase
Movement；King-post 10 is embedded in arc groove 3012, the rotation of limitation platform 301 in the horizontal direction；By the way that barrier assembly is arranged
Limitation platform 301 moves upwards, so that platform 301 is fixed on king-post 10 from three-dimensional space；If it is solid to directly adopt bolt
Fixed, bolt will bear the gravity of platform 301 for a long time, also provide enough pressing forces and platform 301 is avoided to send out relative to king-post 10
Raw movement, it is impaired that bolt is easy to cause king-post 10, and installation accuracy is lower；When the radian of arc groove 3012 is greater than π, 10 side of king-post
Face can not be embedded in arc groove 3012, cannot achieve the installation of platform 301 Yu king-post 10.
Specifically, barrier assembly is clip 40.Clip 40 clamps king-post 10 by bolt, and the active force of bolt is not direct
King-post 10 is acted on, in addition clip 40 need to provide the resistance for preventing 301 upward sliding of platform, and clip 40 is to king-post 10
Chucking power be much smaller than and directly adopt the pressing force of screw bolt reinforcing platform 301.
Lead to 301 upward sliding of platform for the loosening of clip 40, is connected between adjacent clip 40 by second connecting rod 50, it is real
Existing three clips 40 link, when clip 40 loosens, due to three prisms distribution of the corresponding triangular platform of king-post 10, clip 40
It moves upwards, since second connecting rod 50 realizes the rigid connection of even clip 40, the distance between two clips 40 can not contract
Short, clip 40 can not move upwards, and platform 301 can not move upwards.
When pole 303 installs out of plumb, the adjustment of the verticality, horizontal angle, inclination angle and orientation of each antenna is carried out,
Workload when installation is considerably increased, construction period is extended.
Each 302 other end of first connecting rod be equipped with U-bolt 304, each pole 303 by corresponding U-bolt 304 with it is corresponding
First connecting rod 302 connects, and 301 side of platform of same perpendicular is equipped with two first connecting rods 302.Guarantee that pole 303 hangs down
Straight installation, convenient for the installation of later period antenna.
The angle of each king-post 10 and horizontal plane is 88 °~89 °.Avoid king-post 10 and the angle of horizontal plane too small, limitation three
The manufacture height of turret, restricts the application of triangle tower.
Mounting plate 60 is equipped at the top of king-post 10, mounting plate 60 is equipped with lightning rod 70.
For the structural strength for improving three towers, connected by brace 80 between adjacent crossbars 20.
Above embodiment is only the certain preferred embodiments of the utility model, cannot limit the utility model with this
The range of protection, the variation and replacement of any unsubstantiality that those skilled in the art is done on the basis of the utility model
Belong to the utility model range claimed.
