The scope of the utility model protection.
As Figure 1-Figure 5, the present embodiment transmission tower, including tower body 1 and at least one set of cross biling assembly 2, the tower body 1
Including bottom support bar 11 and upper support bar 12, the end of the end of the bottom support bar 11 and the upper support bar 12
End flange disk (unmarked) is respectively arranged with, the upper support bar 12 is supported by the end flange disk and the bottom
Bar 11 is fixedly connected, and cross biling assembly 2 described in every group includes the first cross-arm 21 and the second cross-arm 22, the side of the upper support bar 12
Mounting hole 121 is offered on wall, the mounting hole 121 runs through the upper support bar 12, and the upper support bar 12 is located at institute
The top for stating mounting hole 121 is additionally provided with suspension hook 122；The mounting end of first cross-arm 21 is provided with shackle 211, and described
The end set of two cross-arms 22 has drag hook 221, the tapered structure of gib head of the drag hook 221 so that the gib head of the drag hook 221
Madial wall is inclined plane, and the section of the gib head 221 from top to bottom gradually increases, on the upside of the mounting end of first cross-arm 21
Carrying axle 23, first cross-arm 21 and second cross-arm are respectively arranged with the upside of the mounting end of second cross-arm 22
22 backwards to being set, and the carrying axle 23 of first cross-arm 21 and second cross-arm 22 is stuck in the corresponding suspension hook 122, institute
State shackle 211 and the drag hook 221 is located in the upper support bar 12 through the mounting hole 121, the drag hook 221 is caught on
The shackle 211.
Specifically, the mounting hole 121 through the body of rod is formed in the present embodiment transmission tower on upper support bar 12, and
The first cross-arm 21 and the second cross-arm 22 in cross biling assembly 2 are correspondingly arranged on shackle 211 and drag hook 221, wherein, drag hook 221
The tapered structure of gib head so that during drag hook 221 is connected with shackle 211, drag hook 221 can gradually lacing wire shackle 211, from
And the first cross-arm 21 and the second cross-arm 22 is caused to clamp upper support bar 12；Importantly, in installation process, cross-arm can be with
By the way of the vertical lifting of routine so that the carrying axle 23 on cross-arm is first hung on suspension hook 122, is then gradually laid flat horizontal stroke
Load, and during being laid flat, the first cross-arm 21 and the second cross-arm 22 will pass through shackle 211 and drag hook 221 tightens together, and be
Raising connection reliability, can the mounting end of the first cross-arm 21 and the second cross-arm 22 below using less bolt with it is upper
Portion's support bar 12 connects, and for prior art, cross-arm horizontal need not lift, meanwhile, also reduce live work high above the ground
To adjust the step of end face of cross-arm is alignd with the mounting surface of upper support bar 12, it is only necessary to which cross-arm is hung on suspension hook 122 i.e.
It can complete to pre-install, also, substantial amounts of bolt is saved for cross-arm of the prior art fixation, it is high to reduce operating personnel
The time of idle job, improve field erected efficiency.
Further, the bottom of upper support bar 12 is provided with locating ring 123, and the diameter of the locating ring 123 is by upper
Tapered under, the locating ring 123 is inserted in the upper port of the bottom support bar 11.Specifically, in assembling tower body 1
During, after upper support bar 12 is lifted, the more convenient He of completion upper support bar 12 of locating ring 123 can be passed through
Bottom support bar 11 is alignd, and because locating ring 123 is in funnel-form, locating ring 123 can be oriented to so that upper support bar 12
Entirety is automatically positioned alignment after falling on bottom support bar 11, so as to reduce the time of worker's work high above the ground, reduces worker's
Labor intensity.Preferably, in order to realize upper support bar 12 and the pretension after lifting of bottom support bar 11, the side of locating ring 123
Wall is further opened with open slot 124, and because the diameter of locating ring 123 from top to bottom tapers into, the bottom of locating ring 123 can
It is not inserted into by resistance in the upper port of bottom support bar 11, and during upper support bar 12 is gradually fallen, positioning
The diameter relative with the upper port of bottom support bar 11 of ring 123 gradually increases, and continues lower backwardness, and locating ring 123 will be stuck in bottom
In the upper port of support bar 11, and open slot 124 can realize that locating ring 123 is deformed with more docile bottom support bar 11
Inwall.
The present embodiment transmission tower, by being correspondingly arranged shackle and drag hook in the end of cross-arm, and on upper support bar
Suspension hook is set, and in installation process, two cross-arms first pass through the carrying axle of itself and hung on suspension hook so that on the upside of the end of cross-arm
By suspension hook pull-up, then, during being laid flat cross-arm, coordinate and two cross-arms can be linked together by shackle and drag hook,
Simultaneously as the tapered structure of the gib head of drag hook so that during drag hook catches on shackle, two cross-arms are gradually tensed, with reality
Existing two cross-arms mutually tense and clamp upper support bar, realize quickly installation, during in-site installation need not horizontal lifting it is horizontal
Load, simplifies field erected process so that transmission tower is easy to live Fast Installation, and improves installation effectiveness.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
