The transmission line iron tower with the trilateral structure tower body section has the beneficial effects that firstly, the tower body section adopts the trilateral structure, so as to reduce the floor area and make the selection of tower location more flexible; secondarily, the main materials of the tower body are reasonably arranged according to the asymmetric stress, the strength of three main materials is sufficiently used and the consumption of the tower materials is reduced.
Description
Technical field
The utility model relates to a kind of overhead transmission line iron tower, in particular, relate to the iron tower of power transmission line that a kind of body of the tower section adopts the design of triangle form of structure.
Background technology
The development of China's electric utility is at present advanced by leaps and bounds, and the transmission line of electricity of various electric pressures has all obtained fast development.For reducing the consumption of transmission line construction to social resources to greatest extent, environment-friendly type iron tower of power transmission line such as compact (contracting) type, " F " type have obtained increasing application.This class iron tower has a common characteristic-lead no longer simply to be arranged symmetrically in the both sides of body of the tower, but according to the reasonable Arrangement that requires of surrounding enviroment.
For coordinating mutually, often need to adopt the form of lead asymmetric arrangement, and the asymmetric arrangement of lead directly causes the asymmetric of structure stress with surrounding enviroment.With " F " type tower is example, and two polar conductors are arranged in the same side of body of the tower, the stressed cross-arm side master material that obviously is less than of no cross-arm side master material.The body of the tower section of conventional iron tower of power transmission line adopts the quadrilateral structure of symmetry, is processing and easy for installation simultaneously, and body of the tower master material generally all adopts same specification, promptly main material commons.When quadrilateral structure was applied to " F " shape iron tower, body of the tower master material specification was by the maximum internal force control of cross-arm side master material, and the intensity of not having two main materials of cross-arm side is not in full use, and causes waste.
Body of the tower section to the asymmetric layout iron tower of lead adopts the triangle structure, be that stressed big side adopts two main materials, stressed little sides to adopt single main material, by adjusting the width of triangle structure at stressed larger side, arrange body of the tower master material according to the actual loading situation, make full use of the intensity of three main materials, form of structure is more reasonable, can effectively reduce tower weight and basic material consumption, improves the economy of iron tower of power transmission line.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of simple in structure, compact, the triangle structure body of the tower section iron tower of power transmission line of economical rationality.
In order to overcome the above problems, the utility model is achieved by the following technical solution: it includes: tower leg, body of the tower, tower head and insulator string, described tower head mainly by the lead cross-arm, line bracket and form with the last body of the tower that body of the tower is connected together mutually; Described tower head is gone up the top that body of the tower is fixedly connected on body of the tower by described, and the lead cross-arm is arranged vertically the same side at last body of the tower, and fixedlys connected with last body of the tower respectively.
Described lead cross-arm includes cross-arm and following cross-arm, and described going up on cross-arm and the following cross-arm is connected with two polar conductors by insulator string, and the hanging point of each insulator string all is positioned at the node place of iron tower member; Described lead cross-arm is according to the surrounding enviroment requirement, in the both sides of body of the tower asymmetric arrangement.
Described two polar conductor vertical arrangements guarantee vertical interval and certain horizontal-shift between the last lower wire.
As a kind of improvement, the body of the tower section adopts triangle form of structure, and stressed big side is arranged two body of the tower master materials, and stressed little side is arranged single main material.By optimizing and revising the width of triangle structure in stressed big side, make the maximum internal force of stressed little side master's material suitable substantially with the maximum internal force of stressed big side master's material, the intensity of three main materials all is not fully exerted, and structural shape is reasonable.
Compared with prior art, the beneficial effects of the utility model are: at first, the body of the tower section adopts the triangle structure, has reduced floor space, and the tower position is selected also more flexible; Secondly,, make full use of the intensity of three main materials, reduce tower material consumption according to stressed asymmetry reasonable Arrangement body of the tower master material.With " F " sections tower is example, adopts the triangle steel tubular structure can save tower weight about 30% than quadrangle angle steel structure, can save tower leg base concrete amount about 10%, saves reinforcing bar amount 20%～30%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a triangle form of structure body of the tower section structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model includes: go up cross-arm 1, line bracket 2, go up body of the tower 3, tower leg 4, body of the tower 5, cross-arm 6, tower head 7, insulator string 8 down.
In conjunction with shown in Figure 2, described body of the tower section is a triangle form of structure, stressed big side, is that the cross-arm side is furnished with body of the tower master material, stressed little side, does not promptly have the cross-arm side and arranges single body of the tower master material.
The utility model includes: tower leg 4, body of the tower 5, tower head 7 and wire insulation substring 8, described tower head 7 mainly by the lead cross-arm, line bracket 2 and form with the last body of the tower 3 that body of the tower is connected together mutually; Described lead cross-arm includes cross-arm 1 and following cross-arm 6, described tower head 7 is fixedly connected on the top of body of the tower 5 by described upward body of the tower 3, last cross-arm 1 and following cross-arm 6 are arranged vertically in the same side of last body of the tower 3, and fixedly connected with the upper and lower of last body of the tower 3 respectively.
Described going up on cross-arm 1 and the following cross-arm 6 is connected with two polar conductors by insulator string 8, and the hanging point of each insulator string all is positioned at the node place of iron tower member.Described two polar conductor vertical arrangements guarantee vertical interval and certain horizontal-shift between the last lower wire; The iron tower group immediately, it is certain pre-high that two tower leg bases of cross-arm side have, and guarantees the high fastening rate of iron tower bolt simultaneously, to prevent iron tower guiding line side introversion behind the stringing.
For making the body of the tower structure stress more reasonable, give full play to the mechanical property of each body of the tower master material, alleviate tower weight simultaneously, the body of the tower section adopts the triangle structure, and stressed big side (cross-arm side) is arranged two main materials, the single main material of stressed little side (no cross-arm side) layout.Adjust the width of triangle structure simultaneously, optimize the stress performance of three body of the tower master materials in the cross-arm direction.
At last, it should be noted that above what enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
