Abstract
The utility model belongs to electric pole technical field, discloses a kind of large moment of flexure power steel pipe rod.Form the technical scheme of this device: the thicker successively and steel pipe that radial section is the ellipsoidal structure with minor axis and major axis is formed by bore from top to bottom; Short axial in steel pipe is provided with the reinforcement gusset of at least a slice; Major axis in steel pipe bottom outside face is to being provided with symmetrical feet.This large moment of flexure power steel pipe rod can meet large moment of flexure demand and it has feature rational in infrastructure.
Description
Technical field
The utility model belongs to electric pole technical field, particularly relates to a kind ofly to be used in the terminal of power line or the large moment of flexure power steel pipe rod of corner.
Background technology
In power transmission line, not only comprise straight line carries the stringing pipe bar used, the terminal also comprising conveying circuit or place of turning round uses terminal pole and angle pole.Straight line carries the stringing pipe bar used to be made into circular configuration, and it meets the feature accepting balance, terminal pole and angle pole are made circular tube structure and the imbalance of pulling force then can be caused to form larger moment of flexure, and the diameter of double-rod structure or larger increase steel pipe pole therefore must be used to meet the demand of moment of flexure.And no matter be the diameter adopting double-rod structure or improve pipe bar, not only waste material but also preparation and construction and all there is very large difficulty.
Utility model content
The purpose of this utility model is just to provide and a kind ofly can either meets large moment of flexure demand and its large moment of flexure power steel pipe rod rational in infrastructure.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A kind of large moment of flexure power steel pipe rod, is made up of steel pipe; It is characterized in that: the bore of described steel pipe is thicker successively from top to bottom, and described steel pipe radial section is the ellipsoidal structure with minor axis and major axis; Wherein, the short axial in described steel pipe is symmetrically arranged with two and strengthens gusset.
The additional technical feature forming above-mentioned large moment of flexure power steel pipe rod also comprises:
---the major axis in described steel pipe bottom outside face is to being provided with symmetrical feet.
The large moment of flexure power steel pipe rod of one provided by the utility model, compared with prior art have the following advantages: one, because the radial section forming steel pipe pole steel pipe is the ellipsoidal structure with minor axis and major axis, and its bore is thicker successively from top to bottom, therefore can increase its major axis to moment of flexure, the balance of the moment of flexure that its power line is produced, can realize the needs that corner meets large moment of flexure; Its two, due to forming the major axis in bottom outside face of steel pipe pole steel pipe to being provided with symmetrical feet, therefore can meet the balance of large moment of flexure further.
Accompanying drawing explanation
The structural representation of the large moment of flexure power steel pipe rod that Fig. 1 provides for the utility model;
Fig. 2 is the radial section structural representation of the large moment of flexure power steel pipe rod of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the concrete structure of a kind of large moment of flexure power steel pipe rod provided by the utility model and use principle are described in further details.
As shown in Figure 1, 2, the structural representation of the large moment of flexure power steel pipe rod provided for the utility model.The structure forming this power steel pipe rod is made up of steel pipe 1; And the bore of this steel pipe is thicker successively from top to bottom, and radial section is the ellipsoidal structure with minor axis and major axis.
In the structure of above-mentioned large moment of flexure power steel pipe rod:
---in order to improve the bulk strength of steel pipe pole further, the short axial in steel pipe is provided with the reinforcement gusset 2 and 3 of two (at least a slice or three);
---in addition, the major axis in steel pipe bottom outside face more can improve the balance of its large moment of flexure further to being provided with symmetrical feet 4 and 5.
Namely when this steel pipe pole is as angle pole, namely when power line 6 and 7 pull on this angle pole, form included angle A time, can make the large moment of flexure of pulling force of power line 6 and 7 to the major axis of this angle pole in the same way, therefore can realize with moment of flexure and draw equilibrium of forces, the balance of further raising transmission pole, effectively ensures the safety of transmission line of electricity.
