Technical Field

[2]

The utility model relates to a power transmission apparatus, in particular relates to a self-vertical power transmission tower.

[3]

Background Art

[4]

Electric energy in the conveying process in the far distance, often require some remote areas, such as some traffic is extremely inconvenient remote mountain areas, power transmission in these areas, often requires erecting power transmission tower.

[5]

Can be divided into the power transmission tower as shown in Figure 1 the free-standing the power transmission tower and as shown in Figure 2 the pull wire tower. The present self-supporting steel most widespread application of the power transmission tower, as shown in Figure 1. With the improvement of the power throughput, power transmission tower increasing load and height, when its height of more than 100 meters, the problem of the power transmission tower to : (1) increase the main radius of the main body than the steel pipe will lead to partial-flex ; (2) if the thickness of the wall of the main is too large, not only a waste of steel, cannot play the advantage of high strength steel, and the normal direction of the main surface of the lamellar tearing easily occur ; (3) the main heavy difficult construction, processing and transport. Pulling the pull wire of the power transmission tower at a tower, for more sparsely populated desert area. My many region is densely populated, power verandahs narrow. The use of the transmission tower is greatly limited. As shown in Figure 4, and remains vertical transmission tartans by the external force of the main and disjoint not only have to bear the pressure of the steel tube material must also undertake tension is easy to cause lamellar tearing, the problem of local buckling.

[6]

To this end, to provide a transmission tower, to 200 meters of the power transmission tower, with good bearing performance, low cost, small occupied area, the advantage of convenient construction.

[7]

Content of the utility model

[8]

The above-mentioned problem is to be solved by the following technical scheme: provides a transmission tower, solving the existing transmission tower bearing performance is poor, high cost, space, the shortcoming of the construction is inconvenient.

[9]

The utility model provides a transmission tower, the power transmission tower includes a vertically disposed tower is transversely arranged and a cross arm on the body,

[10]

The tower body is arranged at the base of the main, disjoint transverse member and are connected to form a framework structure, between the main material and the connection point of the node to states the transverse member.

[11]

A main four state in the horizontal plane 90 degrees distribution, the nodes form the upper and lower surfaces of a rectangular hexahedron.

[12]

The node is formed on the same plane of the top surface of the square.

[13]

The number of the top surface of the second, the power transmission tower is divided into three layers.

[14]

states the slanting material respectively connected with the two ends of the adjacent of said main material and transverse member is formed to be oblique surface; each of the main is states braces the surface , disjoint transverse member and is connected with the first end of the triangular.

[15]

The main material and the internal transverse member perfused with concrete steel pipe.

[16]

states the slanting material is provided with a pre-stress of the cable. The cross-section of a steel cable of the main and prestressed to ensure that under the action of the load shall not relieving pressure.

[17]

The node plate is set at the node, the node plate is provided with a plurality of bolt holes, the disjoint states the transverse member and through the bolt hole and the node board is connected.

[18]

The lightning protection device also includes the power transmission tower, and the states the lightning protection device is mounted in the top of the tower the power transmission tower.

[19]

As shown in Figure 5, the structure of the concrete is injected in the main steel tension not only influenced by the pressure, when checking only in the ultimate bearing capacity will consider its pulling force; is provided with a prestressed steel ropes of the disjoint can bear great pulling force; and in this application only disjoint bear the pulling force.

[20]

With the most similar than the prior art, the technical scheme of the utility model has the following beneficial effects:

[21]

1, this application provides a transmission tower, the diameter of the steel pipe of the main is reduced, wall thickness and the node number, the steel of the power transmission tower, the difficulty of construction.

[22]

2, the application provides a transmission tower, thereby reducing the occupied area of the power transmission tower, has the beneficial effect of saving electric power of the corridor.

[23]

3, a steel pipe concrete provided by the application of the main, pressure can bear large; the power transmission tower pressure capability is greatly improved.

[24]

4, disjoint provided by the application of a pre-stressed steel is applied, the pulling force can bear large; providing lateral support to the power transmission tower, bear the shearing force of the cross section of the power transmission tower, the calculation of reducing the length of the main, improve the bearing capacity of the power transmission tower.

[25]

5, the application provides a transmission tower, full use of the steel and concrete performance of the tension of the compression performance, thereby avoiding the lamellar tearing of the large-size steel pipe, the problem of local buckling.

[26]

6, steel pipe concrete provided by the application can be processed in the factory the main, and then is transported to site assembly, after filling concrete and the steel tube, the turning radius of the steel pipe concrete obviously greater than that of the original steel pipe, the long thin than under the same conditions, the internode length can greatly increase, the main is reduced (steel cable) with the disjoint the number of connecting nodes, to reduce the construction cost.

[27]

7, the application provides a during normal use, the power transmission tower, the structure of the concrete is injected in the main steel tension not only influenced by the pressure, when checking only in the ultimate bearing capacity will consider its pulling force; and filled with concrete steel pipe can have a very large pressure, to the relatively weaker force. This can effectively utilize the structure of the concrete to the steel pipe with the advantages of the main body.

[28]

8, the application provides a during normal use, the power transmission tower, is provided with a prestressed steel ropes of the disjoint can bear great pulling force; and in this application only disjoint bear the pulling force. Prestressed for this can effectively utilize the advantages of steel cable as disjoint.

[29]

9, the structure provided by the application of the concrete is injected in the transverse member of the steel pipe, a horizontal component to the disjoint.
