Description
Technical field
The utility model belongs to the transmission pole technical field, relate in particular to by roll of steel plate make have certain taper, its internal fixation is by the reinforced steel pipe body of rod of the transmission line of electricity of reinforcing rib.
Background technology
In recent years, the ultra-high-tension power transmission line steel pipe pole has obtained to use widely, has played fairly obvious social benefit and economic benefit for the development urban and rural power grids.Along with high speed development of national economy, town and country are increasing to the demand of electric power, and the intensity that the present diameter that is rolled into by 8-18 millimeter steel plate that adopts is the steel pipe pole of 400-2000 millimeter is difficult to competent 220KV, 330KV, the 500KV needs until the 750KV extra high voltage network, therefore, wanting to finish setting up of extra high voltage network just must adopt the super thickness steel plate that is not less than 30 millimeters to roll into diameter greater than 2000 millimeters huge steel pipe pole.And this huge steel pipe pole not only exists difficulty on manufacturing process, produces and also exist the carrying and installation difficulty, installs that area occupied is big, cost of production is high and the defective of waste material.
The utility model content
The purpose of this utility model provides the reinforced steel pipe bar of transmission line of electricity that diameter is little, intensity is high.
First technical scheme that realizes the utility model purpose is: the reinforced steel pipe bar of transmission line of electricity, comprise the steel pipe body of rod that at least one is made by roll of steel plate with certain taper, in the described steel pipe body of rod, be set with at least one small-caliber steel pipe body of rod, and fixedly connected between described each steel pipe body of rod by reinforcing rib.
Its additional technical feature is: the described steel pipe body of rod and be placed in and be concentric arrangement between wherein the small-caliber steel pipe body of rod; On the inwall of the described small-bore steel pipe body of rod, be fixed with reinforcing rib; Be arranged side by side between the small-caliber steel pipe body of rod in the described steel pipe body of rod; The small-caliber steel pipe body of rod that is arranged side by side in the described steel pipe body of rod is solid support rod body; The radially section of the described steel pipe body of rod is a rectangle; The radially section of the described steel pipe body of rod is oval.
Second technical scheme that realizes the utility model purpose is: the reinforced steel pipe bar of transmission line of electricity, comprise the steel pipe body of rod that at least one is made by roll of steel plate with certain taper, and fixing on the inwall in the described steel pipe body of rod by reinforcing rib.
Its additional technical feature is: the radially section of the described steel pipe body of rod is a rectangle; The radially section of the described steel pipe body of rod is oval.
The circuit reinforced steel pipe bar that powers up provided by the utility model compared with prior art has the following advantages: one, since in the internal fixation of the steel pipe pole that rolls with general steel plate by reinforcing rib or be set with small-bore steel pipe pole, therefore under the situation that does not increase wall thickness, improve the mechanical strength of transmission line of electricity steel pipe pole, can satisfy the needs that set up of extra high voltage network with the steel pipe pole of common specification; They are two years old, because the radially section of the reinforced steel pipe bar of this transmission line of electricity not only has the polygon or the circular configuration of rule, but also can be designed to rectangle or ellipsoidal structure, therefore, not only can satisfy general stress balance transmission line of electricity set up needs, but also can satisfy as the needs of the large-scale folk prescription of wide-angle angle pole, terminal pole and superelevation to the floodlight lamp stand.

The specific embodiment
Be described further below in conjunction with the structure and the specific embodiment of accompanying drawing the reinforced steel pipe bar of transmission line of electricity provided by the utility model.
Be illustrated in figure 1 as the structural representation of first kind of reinforced steel pipe bar of transmission line of electricity provided by the utility model, including three radially sections that rolled by steel plate that connect with flange 1 (or welding and other modes) is the reinforced steel pipe bar of transmission line of electricity circular or that polygonal steel pipe pole 2 is formed, is fixed with power line cross bar 3 on the steel pipe pole 2 at its top.Be fixed with as shown in Figure 2 concentric small-caliber steel pipe bar 5 in the inside of this steel pipe pole through reinforcing rib 4.Also can fix regularly arranged three small-caliber steel pipe bars 5 (or solid support rod body) as shown in Figure 3, can play the effect that increases the steel pipe pole mechanical strength equally.Be illustrated in figure 4 as the another kind of structural representation of the radially section of the reinforced steel pipe bar of transmission line of electricity, promptly in order further to improve the mechanical strength of the reinforced steel pipe bar of transmission line of electricity, then the small-caliber steel pipe bar 5 in being inserted in steel pipe pole 2 is internally connected with reinforcing rib 6.
In order to satisfy the needs of the large-scale folk prescription of wide-angle angle pole, terminal pole and superelevation to the floodlight lamp stand, it is the shape of ellipse or rectangle that the shape of the reinforced steel pipe bar of transmission line of electricity can roll into as Fig. 5, radially section shown in Figure 6
Be illustrated in figure 7 as the structural representation of second kind of reinforced steel pipe bar of transmission line of electricity provided by the utility model, be that structure includes three steel pipe poles 2 that rolled by steel plate that connect with flange 1 (or welding and other modes) and the transmission line of electricity formed adds steel pipe pole, on the steel pipe pole 2 at its top, be fixed with power line cross bar 3.Directly welding (or other modes connect) has reinforcing rib 6 on the wall of the inside of this steel pipe pole.The transmission line of electricity steel pipe pole of this structure can satisfy the low slightly occasion of desirable strength, to reach the purpose that reduces cost.The radially section of the same reinforced steel pipe bar of this kind transmission line of electricity also can roll into as shown in Figure 5 and Figure 6 ellipse or the shape of rectangle to satisfy the demand.
