Abstract
The utility model belongs to an iron tower for an electric transmission line, in particular to a compact narrow based tower. According to the technical proposal provided by the utility model, the top of a tower pole is the tower top, and the bottom of the tower pole is the tower base; the amount of the tower pole is four and the four tower poles are respectively positioned around the tower; a connecting rod is arranged between the tower poles. The iron tower is characterized in that: the tower pole comprises two angle bars and a cross-shaped connecting frame; the two angle bars are respectively positioned in the opposite angles of the cross-shaped connecting frame, the two edges of the angle bar are respectively jointed with the two edges of the cross-shaped opposite angle. The tower base of such an iron tower is comparatively narrow, therefore, a line passage can be compressed, the floor area of the iron tower can be reduced, and the engineering cost can be lowered.
Description
Technical field
The utility model belongs to a kind of iron tower of used for transmission line, refers in particular to a kind of compact narrow base tower.
Background technology
When setting up ultra-high-tension power transmission line, usually need to use iron tower, traditional iron tower is in order to satisfy required machinery of ultra-high-tension power transmission line and electrical performance indexes, general all the column foot of iron tower is provided with to such an extent that compare broad, its width can reach more than 7 meters, therefore, and when erecting power transmission lines, can take a large amount of soils, cause very big waste.
Summary of the invention
The purpose of this utility model is to design a kind of compact narrow base tower, and the column foot of this iron tower is narrow, therefore, can the compressed lines paths, reduce the iron tower floor space, reduce construction costs.
The technical scheme that provides according to the utility model, at the top of tower bar is cat head, in the bottom of tower bar is column foot, described tower bar has 4 at least, lay respectively at tower around, between the tower bar, connecting rod is arranged, it is characterized in that: described tower bar comprises two angle steel and a cross link, described two angle steel lay respectively in the diagonal angle of cross link, fit with two limits at cross diagonal angle respectively in two limits of angle steel.
The bottom width L of described column foot is 3～6 meters.
The utility model has the advantages that:
1, under identical service condition, the circuit that this project tower forms is compared with conventional two 220kV transmission lines of electricity that return, and about 7 meters of width of corridor compressions are if this project of employing tower 10km circuit has been saved city development land used 70000m altogether
2(104.8 mu), cost of land are saved 2,080 ten thousand yuan by 200,000 yuan/mu, and this project tower floor space is original 1/4 simultaneously, has also saved the column foot land expropriation cost, reduces engineering construction investment.
2, under identical service condition, the circuit that this project tower forms is compared with 220kV steel pipe circuit, and single basic steel tube tower consumable quantity lacks 20～46%, and the tower material is lower 1000～2000 yuan/ton than tubing unit price, has higher economical efficiency so substitute steel pole.
3, the abominable regional tower of narrow for passage, upright tower construction environment is in short supply, not having corresponding tower can be for selecting for use, restriction 220kV line project design and construction under one stable condition, this project is very remarkable for the design of 220kV power transmission sequence provides technical support, economic benefit that obtains and social benefit.

Fig. 2 is an another kind of structure chart of the present utility model.
Fig. 3 is a kind of structure chart that has of the present utility model.
Fig. 4 is the cross-sectional configuration figure of tower bar.
The specific embodiment
As shown in the figure: the top at the vertical tower bar of arranging 3 is a cat head 7, in the bottom of tower bar 3 is column foot 1, described tower bar 3 has 4 at least, lay respectively at tower around, connecting rod 2 is arranged between tower bar 3, described tower bar 3 comprises two angle steel 8 and a cross link 9, and described two angle steel 8 lay respectively in the diagonal angle of cross link 9, fits with two limits at cross diagonal angle respectively in two limits of angle steel 8.The bottom width of column foot 1 is 3～6 meters.During manufacturing, earlier two angle steel 8 are welded in the diagonal angle of cross link 9, with connecting rod 24 tower bars 2 are welded together again, weld the peg 4 of 3 groups of lateral arrangement then on the top of tower bar 3, on peg 4, be provided for hanging the lead hanging point 6 and the wire jumper string hanging point 5 that is used to hang wire jumper of lead again, at last, whole tower is installed on the prefabricated ground.
Fig. 2 is that with the difference of Fig. 1 connecting rod 2 is different with the overlapping mode of treadle 3.Fig. 3 is that with the difference of Fig. 1 the connected mode of lead hanging point 6 is different, and described lead hanging point 6 utilizes the excellent porcelain 8 of lambdoid length to be connected on the peg 4.The bottom width L of described column foot 1 is 3～6 meters
The utility model can use in line channel and Li Ta condition, the restricted city line engineering of construction environment, and effectively the compressed lines paths reduces the iron tower floor space, reduces construction costs.
