Abstract
A tangent tower for heavy ice areas comprises a tower body composed of angle steel and provided with a supporting portion, and a cross arm horizontally arranged is fixed at the upper end of the supporting portion. The tangent tower for heavy ice areas is characterized in that V-shaped hanging lines made of soft materials are arranged at the lower end of the cross arm, the upper ends of the hanging lines are fixedly connected with the cross arm, and hanging points for fixing wires are arranged at the lower ends of the hanging wires. The tangent tower for the heavy ice areas has the advantages of being large in supporting force for the wires, safe and reliable, capable of resisting ice and wind, and convenient to manufacture and assembly due to the trapezoidal cross arm.
Description
Technical field
The utility model relates to a kind of tangent tower, relates in particular to a kind ofly to be used for heavy ice and the more abominable power transmission line of environment is used tangent tower.
Background technology
The remote conveying of electric energy; Need lead be grown distance ground and lay, and tend in the way that lead is laid, in case can produce very big stress to the shaft tower of support wire when having tied thick ice on the lead or having born bigger wind-force through lower heavy icing area and the bigger zone of natural wind of some ambient temperatures; Especially at present be used in the tangent tower in lead stage casing; Owing to much more more to bias toward the weight of support wire own during design, and comparatively ignore the stressed of side direction, so security reliability is relatively poor.
The utility model content
The utility model provides a kind of safe and reliable heavy icing area to use tangent tower for solving the prior art problem.
The technical scheme of the utility model is: a kind of heavy icing area is used tangent tower; Comprise the body of the tower that is made up of angle steel, said body of the tower is provided with the support portion, and this upper end, support portion is fixed with horizontally disposed cross-arm; It is characterized in that: the lower end of said cross-arm is provided with the hanging wire of being processed by soft material; Said hanging wire is in the shape of the letter V, and the upper end of hanging wire is fixedly connected with said cross-arm, and the lower end of hanging wire is provided with the hanging point with fixing cord.
The hanging wire of V font defines laterally moving of lead; After tight hanging wire hangs up lead, hanging wire will be decomposed into vertically upward component and level to the pulling force that makes progress that lead provides to the component of both sides, can more lateral support be provided to lead simultaneously; Through the actual proof of using; The utility model is applicable to maximum ice thickness 30mm, and use in the area of maximum wind velocity 30 meter per seconds, and can bear the circuit of electric pressure 800KV.
As preferably, said support portion and cross-arm connecting portion in the central part of said cross-arm.
As preferably, said hanging wire is provided with two groups, lays respectively at the two ends of said cross-arm, and mirror image distributes along said support portion.
As preferably, said cross-arm is provided with the ground line bracket.
As preferably, the cross section of said cross-arm is trapezoidal, and top margin is longer than on the base of cross section.
As preferably, the interior angle angle of said hanging wire is 76 ~ 96 degree.
In sum, the utlity model has following advantage:
1, the support degree to lead is big, can resist the ice wind resistance, and security reliability is high;
2, trapezoidal cross-arm is convenient to processing and manufacturing and assembling.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1, body of the tower, 2, the support portion, 3, cross-arm, 31, line bracket, 32, hanging wire, 33, hanging point.
Embodiment
With embodiment the utility model is described further below.
Embodiment one:
A kind of heavy icing area is used tangent tower, and is as shown in Figure 1, comprises the body of the tower 1 that is made up of angle steel; Body of the tower 1 is provided with support portion 2, and these 2 upper ends, support portion are fixed with horizontally disposed cross-arm 3, support portion 2 and cross-arm 3 connecting portion in the central part of cross-arm 3; Cross-arm 3 upper surfaces are provided with ground line bracket 31, and the lower surface of cross-arm 3 is provided with two groups of hanging wires 32 of being processed by soft material, lays respectively at the two ends of cross-arm 3; And 2 mirror images distribute along the support portion; Hanging wire 32 is in the shape of the letter V, and the upper end of hanging wire 32 is fixedly connected with cross-arm, and the lower end is provided with the hanging point with fixing cord.
Wherein, the cross section of cross-arm 3 is trapezoidal, and the base of cross section is longer than top margin, and the interior angle angle of hanging wire 32 is 76 degree.
Embodiment two:
Be that with the difference of embodiment one the interior angle angle of hanging wire 32 is 96 degree.
Embodiment three:
Be that with the difference of embodiment one the interior angle angle of hanging wire 32 is 80 degree.。
