The technical solution adopted for the present invention to solve the technical problems is：
The core concept of the design is to design a kind of cross-arm seat of mouse cage shape, is stretched out on cross-arm seat on 360 degree of directions
More cross-arms enter line and outlet requirement with meet multi-angle in power circuit, while overall cross-arm seat passes through upper and lower two kinds and embraced
Bind round to realize fixation.
A kind of universal cross-arm of steel tube tower, including the first cross-arm seat, the second cross-arm seat and the 3rd cross-arm seat, the first cross-arm seat,
Second cross-arm seat and the 3rd cross-arm seat are annular, are had on the periphery of the first cross-arm seat, the second cross-arm seat and the 3rd cross-arm seat
The plane of annular array, there is gusset in plane, and gusset passes through bolt and installs the first cross-arm, the second cross-arm, the 3rd cross-arm, the 4th horizontal
Load, the 5th cross-arm and the 6th cross-arm, the first cross-arm, the second cross-arm, the 3rd cross-arm, the 4th cross-arm, the 5th cross-arm and the 6th cross-arm
It is respectively directed to six different orientation, the first cross-arm, the second cross-arm, the 3rd cross-arm, the 4th cross-arm, the 5th cross-arm and the 6th cross-arm
On have a conducting wire hanging point, conducting wire hanging point is that butterfly ceramic disk is in series；First cross-arm seat, the second cross-arm seat and the 3rd cross-arm seat
There is connecting hole between cross-arm, the internal diameter of the first cross-arm seat, the second cross-arm seat and the 3rd cross-arm seat is more than in cross-arm seat setting height(from bottom)
The external diameter height of corresponding tower body.
Preferably, the first cross-arm, the second cross-arm, the 3rd cross-arm, the 4th cross-arm, the 5th cross-arm and the 6th cross-arm length phase
Together, the air line distance on cross-arm between conducting wire hanging point should be outside high-tension current breakdown region.
Preferably, the first cross-arm, the second cross-arm, the 3rd cross-arm, the 4th cross-arm, the 5th cross-arm and the 6th cross-arm are segment separator
Structure, it is bolted between two valves.
Second anchor ear bottom is conical sleeve, and the taper of conical sleeve is equal to outside the taper of tower body and the minimum of conical sleeve
Footpath is equal to the external diameter that the 3rd cross-arm seat lower surface corresponds to tower body, is the second snap ring at the top of the second anchor ear, the second snap ring external diameter is equal to
3rd cross-arm seat internal diameter, the second snap ring periphery have the second locking hole.
Preferably, the bending edges number of the second anchor ear is equal to tower body bending edges number.
Preferably, the second anchor ear is segment separator structure, is bolted between two valves.
It is conical sleeve at the top of first anchor ear, the taper of conical sleeve is equal to outside the taper of tower body and the maximum of conical sleeve
Footpath is equal to the external diameter that the first cross-arm seat upper surface corresponds to tower body, and the first anchor ear bottom is the first snap ring, and the first snap ring external diameter is equal to
First cross-arm seat internal diameter, the first snap ring periphery have the first locking hole.

A kind of universal cross-arm of steel tube tower of the present invention, prior art, which compares caused beneficial effect, is：
1) between traditional tower body cross-arm it is independently installed, structural strength deficiency, and the first cross-arm seat in the design, the
Three-decker above and below two cross-arm seats and the 3rd cross-arm seat composition, difference carry ground wire, live wire and zero line, bulk strength is high, can
Meet the transmission line of electricity requirement of senior middle school's low pressure different size.
2) traditional tower body cross-arm enters line and outlet angle after the completion of welding and can only be limited in the range of a very little,
And each layer of cross-arm can receive the inlet wire in 360 directions in the design, can also disclosure satisfy that various to any direction outlet
The transmission of electricity requirement of landform.
3) traditional transmission line of electricity is required for adding wire extra strainer, and power transmission line is from one layer in the design
The tension to power transmission line, energy can be so achieved that after cross-arm inlet wire from adjacent layer or phase interlayer cross-arm hanging wire point outlet
Enough effectively reduce the phenomenon of transmission line of electricity galloping.
4) extra soldered construction operation platform is needed on traditional tower body, and large-sized cage structure can in the design
As workmen rest and operation platform, be advantageous to construction safety.
5) traditional tower body cross-arm needs successively welding one by one, and cross-arm mechanism whole in the design can be on ground
Face be completed after from tower top integral hoisting, modularization assembling can be realized, can greatly accelerating construction progress.
