The purpose of this utility model is to overcome the weak point of above-mentioned background technology, and proposes transmission line of electricity cross cantilever
Beam only post self-balancing basis, it is prevented effectively from tower material and is corroded and the rough sledding flooded occurs.
This utility model transmission line of electricity cross cantilever beam only post self-balancing is basic, and it is positioned at the lower section of transmission of electricity tower leg, and it is special
Levy and be: it includes cross cantilever beam, basis principal post, enlarged footing, tapered pole, cat ladder and guardrail；At described cross cantilever beam
Being arranged on the upper end of the rounded basic principal post of upper surface, the outward flange of each described cross cantilever beam and basis principal post is all provided with
Being equipped with guardrail, be equidistantly provided with tapered pole on described cross cantilever beam, described basic principal post is disposed vertically, and under
End extend into below ground to be passed through together with concreting with enlarged footing；Described cat ladder is arranged on described basic principal post
Side, and along ground to the top of basis principal post.
In technique scheme: described transmission of electricity tower leg is connected by the foundation bolt bolt arranged in tapered pole, and
Form hinged column base structure.
In technique scheme: the center of described basic principal post and power transmission tower are centrally located on same plumb line；Institute
A diameter of 1.6 meters-2.6 meters of the basic principal post stated；Described foundation main column section is that uiform section is solid or hollow structure, described
The outline of basic principal post be hollow square or hollow ring cross section.
In technique scheme: described basic principal post to 1.5 meters of top, is provided with cat ladder along ground.
In technique scheme: when ground is soft foundation, there is pile foundation or micro-in described enlarged footing arranged beneath
Pilework.
In technique scheme: described cross cantilever beam is variable cross-section xoncrete structure, and described cross cantilever
Beam free end cross-sectional area is little, and the root section area that described cross cantilever beam is connected with basis principal post is big.
This utility model has the advantage that 1, power transmission tower frame stands in distance ground has on the cantilever beam of certain altitude, can
Corroded and the rough sledding flooded occurs being prevented effectively from tower material, also reduced the overhead transmission line occupation of land on ground empty
Between, make transmission tower not limited by place, from without hindering production activity around and traffic circulation.
2, only post brace type basis has certain altitude, while satisfied design span, can reduce the system of angle steel tower
Make height, or do not change original shaft tower height, improve the hanging point height of shaft tower.

Detailed description of the invention
Describe performance of the present utility model below in conjunction with the accompanying drawings in detail, but they are not intended that this utility model
Restriction, the most for example, simultaneously by illustrate advantage of the present utility model will become clearer from easy to understand.
With reference to shown in Fig. 1-6: this utility model transmission line of electricity cross cantilever beam only post self-balancing basis, it is positioned at power transmission tower
The lower section of tower leg 7, it is characterised in that: it includes cross cantilever beam 1, basis principal post 2, enlarged footing 3, tapered pole 4, cat ladder 5 and protects
Hurdle 6；The upper end of the rounded basic principal post 2 of upper surface, each described cross cantilever it is arranged at described cross cantilever beam 1
The outward flange of beam 1 and basis principal post 2 is provided with guardrail 6, is provided with tapered pole 4 on described cross cantilever beam 1；Described
