Description
Technical field
The utility model relates to for electrical domain, refers to especially four post steel pipe poles for a kind of high voltage power transmission.
Background technology
Along with the sustainable development of Chinese national economy, urban power consumption increases suddenly, will get more and more at the 110kV of urban spraw ultra-high-tension power transmission line.Because cable run involves great expense, China can't generally adopt at present, so inevitable take overhead wire as main.
The feature of steel pipe pole is mainly that conductor cross-section is large, multiple voltage, loop bar altogether, and available corridor is narrow and small, is often positioned at side, street or isolation flower bed, and root is opened very little.Because steel pipe pole floor space is little, handsome in appearance, can incorporate well urban environment, therefore in urban electricity supply construction, be used widely.
But because China urban power consumption increases severely, transmission line of electricity load is more and more higher, a lot of common steel pipe poles have been difficult to bear high-tension line load, especially in corner or end.
Utility model content
The utility model proposes four post steel pipe poles for a kind of high voltage power transmission, can bear larger load of roadway, can use for transmission line of electricity corner or end.
The technical solution of the utility model is achieved in that
A kind of four post steel pipe poles for high voltage power transmission, its agent structure comprises:
Shaft, is fixedly formed by multiple horizontally disposed connecting portions by four steel pipe columns;
Described connecting portion is square or rectangular frame, and its four bights are for four steel pipe columns of fixing described shaft;
The top position of described shaft is provided with multiple cross-arms, for setting up power line.
In technique scheme, four bights of described connecting portion adopt be nested with described steel pipe column outside and with suitable connecting portion cylinder or the multiple connecting portion annulus formation of described steel pipe column external diameter.
In technique scheme, described steel pipe column is formed by fixedly connecting by multistage steel pipe.
Further, described steel pipe can be seamless steel pipe or ERW.
Further, every two sections of described steel pipes can be fixedly connected with by flange, also can be fixedly connected with by screw or bolt, or be welded and fixed.
In technique scheme, the square of described connecting portion or rectangular frame are inner is the network forming of being interlocked by steel pipe or steel pole, and such as parallel with frame edge or vertical, entirety is the grid of well word shape; Or there is the grid at certain angle of inclination with frame edge.
Further, the sectional area of described connecting portion framework can progressively successively decrease from bottom to top.
In technique scheme, the multistage steel pipe length of described composition steel pipe column not equates, is positioned at the length that the length of every section of steel pipe at position on the lower can be greater than the every section of steel pipe that is positioned at middle and upper part.
In technique scheme, described cross-arm can be arranged on connecting portion place, can certainly be arranged on other positions of steel pipe column pipe shaft.
In technique scheme, described cross-arm can adopt the symmetrical structure centered by shaft, and preferably adopts triangle, and certain leg of frame that specifically can connecting portion is as the leg-of-mutton limit of a side cross-arm; Or be positioned at the pipe shaft of same level position using two steel pipe columns as leg-of-mutton two summits of cross-arm.
In sum, because the utility model has adopted four steel pipe columns, and use multiple cancellated connecting portions to reinforce, make it can either bear larger line load and kept steel pipe pole simplicity generosity, advantage handsome in appearance.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, Figure 2 and Figure 3, four post steel pipe poles for high voltage power transmission of the present utility model, its agent structure comprises:
Shaft, is fixedly formed by multiple horizontally disposed connecting portions 8 by four steel pipe columns 1 (only illustrate in diagram a side two);
Described connecting portion 8 is square or rectangular frame (as shown in Figures 2 and 3), and its four bights are for four steel pipe columns 1 of fixing described shaft;
The top position of described shaft is provided with multiple cross-arms 4, for setting up power line.
In technique scheme, four bights of described connecting portion 8 adopt be nested with described steel pipe column 1 outside and with suitable connecting portion cylinder 5 or the multiple connecting portion annulus formation of described steel pipe column 1 external diameter, its bight is the shape of connecting portion cylinder 5 as shown in Figure 2.
