Abstract
The utility model relates to a kind of structure that improves electric power pylon cross-arm vertical bearing capacity, comprise electric power pylon, the topping wire cross-arm outer end of described electric power pylon is connected with upper strata wire jumper cross-arm, wire jumper cross-arm outer end, described upper strata is connected with jumper string, and wire jumper cross-arm outer end, described upper strata is connected with electric power pylon head by suspension rod.The vertical active force that the utility model adopts hanging rod structure that the weight of jumper string and the weight of wire jumper cross-arm are caused is directly delivered to iron tower main material by suspension rod, can make smaller vertical rigidity wire jumper cross-arm meet structural bearing requirement, the cost of structure is lower, and the outward appearance displacement of structure also can be smaller.
Description
Technical field
The utility model relates to electric power pylon structure, particularly a kind of structure that improves electric power pylon cross-arm vertical bearing capacity.
Background technology
The wire cross-arm of electric power pylon is the external long wire jumper cross-arm of meeting often; and the weight of wire jumper cross-arm and the weight of jumper string can cause vertical active force; therefore conventional structure must strengthen the thickness of wire jumper cross-arm; but this not only can increase the use amount of material, and outward appearance vertical deformation is also larger.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure that improves electric power pylon cross-arm vertical bearing capacity, and not only cost is lower, and appearance deformation is little.
To achieve these goals, the technical solution of the utility model is: a kind of structure that improves electric power pylon cross-arm vertical bearing capacity, comprise electric power pylon, the topping wire cross-arm outer end of described electric power pylon is connected with upper strata wire jumper cross-arm, wire jumper cross-arm outer end, described upper strata is connected with jumper string, and wire jumper cross-arm outer end, described upper strata is connected with electric power pylon head by suspension rod.
Further, described suspension rod upper end is connected with the main material of electric power pylon head, and described suspension rod lower end is connected with wire jumper cross-arm outer end, upper strata.
Further, described suspension rod upper end tie point is positioned at the ground wire cross-arm below of electric power pylon.
Compared with prior art, the utlity model has following beneficial effect: the vertical active force that this electric power pylon adopts hanging rod structure that the weight of jumper string and the weight of wire jumper cross-arm are caused is directly delivered to the main material of head by suspension rod, can make smaller vertical rigidity wire jumper cross-arm meet structural bearing requirement, the cost of structure is lower, and the outward appearance displacement of structure also can be smaller.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1-topping wire cross-arm, 2-upper strata wire jumper cross-arm, 3-jumper string, 4-suspension rod, 5-head, 6-ground wire cross-arm, layer conductor cross-arm under 7-, 8-lower floor wire jumper cross-arm.
The specific embodiment
As shown in Figure 1, a kind of structure that improves electric power pylon cross-arm vertical bearing capacity, comprise electric power pylon, topping wire cross-arm 1 outer end of described electric power pylon is connected with upper strata wire jumper cross-arm 2, wire jumper cross-arm 2 outer ends, described upper strata are connected with jumper string 3, and wire jumper cross-arm 2 outer ends, described upper strata are connected with electric power pylon head 5 by suspension rod 4.
In the present embodiment, described suspension rod 4 upper ends are connected with the main material of electric power pylon head 5, and described suspension rod 4 lower ends are connected with wire jumper cross-arm 2 outer ends, upper strata, and described suspension rod 4 upper end tie points are positioned at ground wire cross-arm 6 belows of electric power pylon.
In the present embodiment, lower layer conductor cross-arm 7 outer ends of described electric power pylon can also be connected with lower floor's wire jumper cross-arm 8, described lower floor's wire jumper cross-arm 8 outer ends are connected with jumper string 3 lower ends of wire jumper cross-arm 2 outer ends, upper strata by flexible pull wire, to prevent that jumper string 3 from swinging.
The vertical active force that the utility model adopts suspension rod 4 structures that the weight of jumper string 3 and the weight of wire jumper cross-arm are caused is directly delivered to iron tower main material by suspension rod 4, can make smaller vertical rigidity wire jumper cross-arm meet structural bearing requirement, the cost of structure is lower, and the outward appearance displacement of structure also can be smaller.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
