Description
Technical field
The utility model relates to the transmission line of electricity field, in particular to a kind of electric power line pole tower.
Background technology
At present, the shaft tower that uses in the domestic and international overhead transmission line mainly comprises several classes such as wooden stick, concrete frame, prestressed concrete bar, concrete filled steel tube bar, steel pipe pole and iron tower.But these traditional transmission towers are owing to its problem of drawing materials, and therefore the problem that the ubiquity quality is heavy causes construction and operation maintenance difficulty, freight height; And defective such as that traditional transmission tower also has is perishable, corrosion or cracking, poor durability, application life is shorter; And owing to use bolts in a large number in installation, maintenance cost is higher, and easy generation windage yaw, ice sudden strain of a muscle, thunderbolt etc. under extreme natural environment, and existing shaft tower may cause circuit appearance tripping operation even generation stoppage in transit accident.Existing shaft tower is in order to strengthen the steadiness of the body of rod, the wall thickness of its body of rod is designed to uniform-dimension from top to bottom, though this structure has improved steadiness, has increased the preparation material, increase the weight of shaft tower simultaneously, caused the human and material resources wasting of resources in preparation and the transportation.
The utility model content
The utility model aims to provide a kind of electric power line pole tower, and is bigger with electric power line pole tower quality in the solution prior art, shaft tower preparation, cost of transportation technical problems of high.
To achieve these goals, the utility model provides a kind of electric power line pole tower, comprises the body of rod and the cross-arm that is fixed on the body of rod, and this body of rod is the hollow taper body, and the pipe thickness of conical tube reduces gradually from boring the end to the vertex of a cone.
Further, the body of rod and cross-arm are made by epoxy resin.
Further, cross-arm vertically is provided with respect to the body of rod.
Further, cross-arm is a hollow tube.
Further, the pipe thickness at the body of rod awl end is 32.4mm, and the pipe wall thickness of the body of rod vertex of a cone is 13mm.
Further, the external diameter at the body of rod awl end is 331mm, and the external diameter of the body of rod vertex of a cone is 190mm.
Further, cross-arm is fixed on the upper end of the body of rod by the cross-arm anchor ear, and it is apart from body of rod vertex of a cone 560mm.
Further, has flange arrangement at the bottom of the awl of the body of rod.
The electric power line pole tower that the utility model provides, because its body of rod is the hollow taper body, and the tube wall of conical tube reduces gradually from boring the end to the vertex of a cone, this just makes shaft tower under the prerequisite that guarantees steadiness, greatly alleviated the weight of the body of rod, be convenient to transportation, the installation and maintenance of electric power line pole tower, also save cost simultaneously.
Description of drawings
Figure of description is used to provide further understanding of the present utility model, constitutes a part of the present utility model, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, does not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 shows the structural representation of the described shaft tower of the utility model specific embodiment.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment in the utility model can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Embodiment
Electric power line pole tower as shown in Figure 1 comprises the body of rod 1 and the cross-arm 2 made by epoxy resin.Cross-arm 2 is fixed on the upper end of the body of rod 1 by cross-arm anchor ear 3, and cross-arm 2 is perpendicular to the body of rod 1.Wherein, the body of rod 1 is the hollow taper body, and the pipe thickness of conical tube reduces gradually from boring the end to the vertex of a cone.Because the thick end of tube wall reduces gradually from boring the end to the vertex of a cone, therefore significantly reduced the raw material consumption for preparing this shaft tower.Cross-arm 2 also is a hollow tube, has saved raw material, has alleviated weight.
Electric power line pole tower as shown in Figure 1, the length of the body of rod are 10.6 meters, and the external diameter at the 1 awl end of the body of rod is 331.04mm, and the external diameter of the body of rod 1 vertex of a cone is 190mm.The pipe thickness at the 1 awl end of the body of rod is 32.4mm, and the pipe wall thickness of the body of rod 1 vertex of a cone is 13mm, and the thick end of tube wall reduces gradually from boring the end to the vertex of a cone.Because the minimizing gradually of wall thickness has significantly reduced the consumption of epoxy resin, thereby has alleviated the overall weight of shaft tower.Cross-arm 2 is fixed on the described body of rod 1 upper end by cross-arm anchor ear 3, and preferably, at a distance of 560mm, under this distance, the overall structure of shaft tower is more firm between the cross-arm 2 and the body of rod 1 vertex of a cone, and position of centre of gravity is reasonable.
Preferably, has flange arrangement 4 at the bottom of the awl of the body of rod 1.Flange arrangement 4 is used for the body of rod 1 is fixed on ground or other fixed parts.
According to industry standard this shaft tower is carried out load test, at 90 degree wind-force, be equipped with under the work condition state of anchor, gained load test data: Fx is 349.712, and Fy is 974.033, and Fz is 7786.696, and every data all satisfy the requirement to shaft tower intensity.
In the utility model, the awl bottom of the body of rod divides (being the top load place) thickness to be set to larger than the thickness at the body of rod vertex of a cone (promptly low load place), the bearing function of material has obtained good performance, make shaft tower under the prerequisite that keeps good stability, alleviate overall weight, and saved cost simultaneously.The electric power line pole tower body of rod in the utility model adopts epoxy resin to make, have characteristics such as intensity height, light weight, corrosion-resistant and fatigue performance, endurance quality and electrical insulation capability be good, and because the minimizing of materials, overall weight descends, and is convenient to transportation and maintenance.In addition, the flange that body of rod awl bottom is provided with can be used for the fixing of electric power line pole tower, makes that the installation of shaft tower is very simple, convenient.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
