Abstract
The utility model discloses a homo-tower dual- loop straight line tower, characterized by lower height of the tower, less steel consumption and good effect of lightning shielding. The homo-tower dual-loop straight line tower comprises a tower body and a tower head. The tower head comprises an upper lead cross-arm, a middle lead cross-arm and a lower lead cross-arm, which are successively arranged in parallel from the top of the tower body. In the direction of plumb line, the two inclined planes of the middle lead cross-arm and the two inclined planes of the lower lead cross-arm are all arranged between the base plane of the middle cross-arm and the base plane of the lower cross-arm. The utility model is advantageous in that the whole height of the tower body is lowered, and lightning shielding is facilitated, and steel consumption is reduced, for the distance between the base plane of the upper cross-arm and the base plane of the middle cross-arm, compared with prior art, is shortened due to the fact that the two inclined planes of the middle lead cross-arm are arranged below the base plane of the middle cross-arm.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
By shown in Figure 1, common-tower double-return road tangent tower, comprise body of the tower 7 and tower head 9, described tower head 9 comprises the upper conductor cross-arm that is set up in parallel successively from body of the tower 7 tops, middle lead cross-arm and lower wire cross-arm downwards, described upper conductor cross-arm comprise one horizontally disposed go up that cross-arm basal plane 1 links to each other with two ends with last cross-arm basal plane 1 be symmetricly set on body of the tower 7 both sides first on cross-arm inclined-plane 4B on the cross-arm inclined-plane 4A and second, described on cross-arm basal plane 1 be positioned on first on the cross-arm inclined-plane 4A and second on the cross-arm inclined-plane 4B; In described the lead cross-arm comprise one horizontally disposed in cross-arm basal plane 2 link to each other with two ends with middle cross-arm basal plane 2 be symmetricly set on body of the tower 7 both sides first in cross-arm inclined-plane 5B among the cross-arm inclined-plane 5A and second; Described lower wire cross-arm comprises first time cross-arm inclined-plane 6A and second time cross-arm inclined-plane 6B of being symmetricly set on body of the tower 7 both sides that a horizontally disposed down cross-arm basal plane 3 links to each other with two ends with following cross-arm basal plane 3; The horizontal length of cross-arm basal plane 2 is greater than the horizontal length of last cross-arm basal plane 1 and following cross-arm basal plane 3 in described; on the plumb line direction, in described first among the cross-arm inclined-plane 5A, second cross-arm inclined-plane 5B, first time cross-arm inclined-plane 6A and second time cross-arm inclined-plane 6B all between middle cross-arm basal plane 2 and following cross-arm basal plane 3.In addition, the cross-arm basal plane also can be positioned on first on the cross-arm inclined-plane and second under the cross-arm inclined-plane on the above.Optimal way is for as shown in Figure 1, and the described cross-arm basal plane 1 of going up is positioned on first on the cross-arm inclined-plane 4A and second on the cross-arm inclined-plane 4B, adopts said structure, is convenient to the layout of high-tension line.
Under the same conditions, as shown in Figure 2, conventional common-tower double-return road tangent tower is when design, because the horizontal length of cross-arm basal plane 11 is greater than the horizontal length of cross-arm basal plane 10 conventionally in the routine, so consider the distance between the cross-arm inclined-plane 12 in the lead 8B that hangs on the hanging point of lead cross-arm conventionally and the routine, because lead 8B is vertical hanging aloft, under the wind-force effect, can oscillate, for lead 8B and in the routine is not bumped between the cross-arm inclined-plane 12, guarantee conventionally to keep suitable distance L1 between the cross-arm basal plane 11 in the cross-arm basal plane 10 and routine; And the utility model common-tower double-return road tangent tower is when design; as shown in Figure 1; consider the lead 8 that hangs on the hanging point of upper conductor cross-arm and the distance between the middle cross-arm basal plane 2; lead 8 and between the middle cross-arm basal plane 2 is not bumped, so will guarantee to keep between cross-arm basal plane 1 and the middle cross-arm basal plane 2 suitable distance L2.Owing to also be provided with cross-arm inclined-plane 12 in the routine between the cross-arm basal plane 11 in the conventionally cross-arm basal plane 10 of conventional common-tower double-return road tangent tower and the routine; and there is not in first cross-arm inclined-plane 5B among the cross-arm inclined-plane 5A and second between the last cross-arm basal plane 1 of the utility model common-tower double-return road tangent tower and the middle cross-arm basal plane 2; so obviously; when design, the distance of L1 is greater than the distance of L2.In addition; because the horizontal length of middle cross-arm basal plane 2 is greater than the horizontal length of following cross-arm basal plane 3; so the lead 8A that hangs on the hanging point of lead cross-arm during design the time only need be considered to make does not bump with the end of following cross-arm basal plane 3 and gets final product; during for the common-tower double-return road tangent tower design of routine also is like this; promptly guarantee the lead 8C that hangs on the hanging point of lead cross-arm in the routine not with routine under the end of cross-arm basal plane 13 bump; therefore the middle cross-arm basal plane 2 of the utility model common-tower double-return road tangent tower and the distance between the following cross-arm basal plane 3 can and the routine of the common-tower double-return road tangent tower of routine in distance between cross-arm basal plane 11 and the routine time cross-arm basal plane 13 be consistent; meet the design instructions for use fully; comprehensive the above as can be known; the height of the whole tower head 9 of the utility model common-tower double-return road tangent tower can be reduced; thereby make the height of whole body of the tower 7 also can obtain corresponding reduction; help taking shelter from the thunder; in addition; the reduction of the whole height of body of the tower 7; the use amount of steel can also be effectively saved, ample resources can be saved.For example, under the certain situation of other design objective, exhale to claim that height is that the whole height of the utility model common-tower double-return road tangent tower of 36 meters is that the whole height of common-tower double-return road tangent tower of 36 meters routine will reduce 1.8 meters than exhaling the title height, simultaneously, the steel use amount also reduces 0.427 ton.
