Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of four tower tower head structures, including two water The connecting rod 1 being parallel to each other is equalled, is respectively connected with arch support bar 2, two arch support bars at the top of two connecting rods 1 2 both ends are spirally connected at left and right sides of two connecting rods 1 respectively, and uniform crossover is bolted between two arch support bars 2 One reinforcing rod 13,2 bottom surface central location of arch support bar described in two sides are respectively connected with the first pull rod 11, and two described first 11 bottom of pull rod is connected, and two 11 junction bottoms of the first pull rod are connected with the first insulator chain 4, two arches The outer wall of support rod 2 is spirally connected there are two link block 3, and the link block 3 on two 2 outer walls of arch support bar is along arch branch 2 vertical axis of strut is symmetrical, and four 3 tops of link block are bolted with strut 12, intersects between four struts 12 and connects It is connected to the second reinforcing rod 9, four 12 tops of strut are bolted with lightning-arrest line bracket 8, four struts 12 opposite one Face lateral wall is bolted with cross bar 7, intersects between the two neighboring cross bar 7 and is bolted with third reinforcing rod 14, two neighboring Opposite one end is welded with singletree 15 between the cross bar 7, and the opposite one end in two neighboring 7 bottom of cross bar is respectively connected with Two pull rods 10, second pull rod 10 are located at the outside of singletree 15, and two 10 bottoms of the second pull rod are connected, two institutes It states 10 junction bottom of the second pull rod and is respectively connected with the second insulator chain 6, four opposite one sides of the strut 12 are welded with tiltedly Strut 5, the other end of the two neighboring hound 5 are spirally connected with two 15 bottoms of singletree respectively.
