Abstract
The invention relates to a high-voltage power transmission iron tower with a tower neck, which belongs to the technical field of power transmission and distribution. A segment of quadrangular prism truss is arranged between a tower head and a tower body and used as the tower neck, a neck transverse baffle is arranged at the upper part, a tower body bottle mouth transverse baffle is seated at the lower part, and four lateral surfaces formed by four neck main materials are all provided with neck web rods. The combined strength and the rigidity of the neck main materials and the neck web rods are slightly smaller than the strength and the rigidity of a tower head lower crank arm and a tower body bottle neck segment which are connected with the neck main materials and the neck web rods, the iron tower can be controlled to be damaged at the tower neck, and the tower body and the tower head are protected from being damaged and are convenient to restore. Particularly, the rigidity of each cross section of the tower neck is more balanced, the line breaking and tension impact resisting performance is farther superior to that of an open bottle neck, and the heavy ice and violent wind resisting performance is improved. The invention is used for high-voltage power transmission lines.
Description
The technical field power transmission and distribution project.
The existing high tension transmission iron tower of background technology, control does not damage the member of happening part.Therefore, the happening part randomness of iron tower damage is big, uncontrollable.It is difficult that this just causes iron tower to repair: difficulty is done prediction scheme, the difficult remanufactured component that is equipped with, and workload is big, length consuming time.
The technical problem that summary of the invention the present invention will solve is: set up security personnel's parts at the iron tower suitable position, make the damage of iron tower occur in security personnel's parts, guarantee that other part of iron tower is intact.
The technical scheme that the control iron tower damages happening part is: set up the tower neck in the junction of tower head and body of the tower, with " bottleneck " of " one section tower neck " alternative existing iron tower, connect tower head and body of the tower with the tower neck.
Tower neck B (accompanying drawing) is one section quadrangular truss, is formed by connecting with bolt neck master material (6), neck web member (4), neck tabula (3).There is bag neck tabula (3) within it the upper end of four neck master materials (6), and the lower end is sitting on the bottleneck tabula (5) of body of the tower C.There is neck web member (4) tower neck four sides.The two ends of neck master material (6) use junction plate to be connected with the main material (2) of body of the tower master material (7), tower head A respectively.Neck master material (6) is used the equal leg angle manufacturing, and its material is identical with the material of body of the tower master material (7) that links to each other and tower head master material (2); Its cross-sectional area is all more smaller than the cross-sectional area of the cross-sectional area of body of the tower master material (7) and tower head master material (2).Neck web member (4) is used the equal leg angle manufacturing, and its material is identical with the material of continuous body of the tower web member (8) and tower head web member (1), and its cross-sectional area is all more smaller than the cross-sectional area of the cross-sectional area of body of the tower web member (8) and tower head web member (1).
The structure of body of the tower, tower head, member are with existing tower.All kinds of existing towers add the tower neck and form the new all kinds of tower neck high tension transmission iron tower that has.
Can know that by the mechanics of materials component strength, rigidity are all amassed and are directly proportional with construction material coefficient of elasticity, net section.So, all little than tower head, the intensity of body of the tower member, rigidity with the intensity of the tower neck member of material small bore, rigidity.Therefore, the iron tower overload damages and will occur in the tower neck.
Have the advantage of tower neck high tension transmission iron tower to be: 1, the tower neck produces distortion, bearing load earlier when iron tower carries; 2, when iron tower overload desire bad time, the tower neck produces the distortion bending earlier, damages unloading with self, thereby has protected body of the tower, tower head; 3, when iron tower is impacted by broken string, because of the tower neck in abutting connection with tower head, its rigidity is again less than tower head; And be cylinder, each cross section rigidity is balanced, so; Tower neck impact resistance is much better more than a bottleneck of existing tower, and the performance of anti-heavy ice, anti-blast improves; 4, tower neck protection body of the tower is not bad even tower head is not bad, and the iron tower repair can be begun from bottleneck; 5, iron tower is just in case impaired, and the damage happening part must be done the reparation prediction scheme well at the tower neck, is equipped with remanufactured component well, and workload is little, and is consuming time few.
Appended drawings is that tower neck high tension transmission iron tower single line drawing is arranged.
The high joint in the tower body pass of specific embodiment tower neck is long.The length and width of each cross section envelope rectangle of tower neck equal the length and width of body of the tower bottleneck.Neck tabula (3) and the frame of body of the tower bottleneck tabula (5), the configuration of built-in horizontal bar structure are identical, and construction material model, material are identical.The collocation form of neck web member (4) is with the collocation form of the body of the tower web member (8) of body of the tower pass; Neck web member (4) equates with the oblique angle of the body of the tower web member (8) of body of the tower pass with the oblique angle α of neck master material (6).
The tower neck should make combined strength, the rigidity of neck master material (6), neck web member (4) be slightly less than intensity, the rigidity of tower head lower bent lever through mechanical calculation; The intensity of tower head lower bent lever, rigidity are slightly less than intensity, the rigidity of body of the tower pass again, and adjust the associated components size in view of the above.Afterwards, do model tower simulated test earlier, do real the carrying of true type tower again and test, identify iron tower and decrease earlier really, finally confirm tower neck and affiliated full tower structure thereof in the tower neck.
