Fig. 3 is the cross-sectional view perpendicular to cross-arm body length direction of embodiment 1.
Specific embodiment
With reference to embodiment, the technical solution of the utility model is described in further detail, but not structure
Any restrictions of pairs of the utility model.
In order to more clearly be illustrated to the utility model, embodiment is listed below to illustrate the excellent of the utility model
More property.
Embodiment 1
As shown in Figure 1-Figure 3, a kind of cross-arm of transmission tower, the cross-arm body being connected including the shaft tower ontology A with peripheral hardware
1；The two sides of the cross-arm body 1 are equipped with multiple support plates 3, and the two sides of the cross-arm body are additionally provided with along cross-arm body 1
The metal otter board 2 that extends of length direction, the metal otter board 2 passes through the described support of support plate 3, the metal otter board
There is handrail in 2 outside.
Handrail is omitted in the top view of Fig. 2, it is seen that cross-arm body 1 and support plate 3.
In practical applications, metal otter board 2 generally requires concordant with the upper surface of cross-arm body so that it is convenient to personnel's row
It walks.Metal otter board 2 is light-weight, people can be supported to walk, and improves support force by support plate 3.And peace is improved by handrail
Quan Xing.This programme improves in existing structure, and improvement cost is low, reasonable in design, not will increase original cross-arm
Weight.
As the further preferred of the present embodiment, the handrail includes more vertical bars 4 and is arranged in helping for the top of vertical bar 4
Hand lever 5, the vertical bar 4 are arranged in the end of support plate 3 and correspond with support plate 3.So the effect of support plate 3 is not
Metal otter board 2 is only supported, fixed handrail, as far as possible reduction number of devices is also used to, reduces failure rate and structure can
It leans on.
In the present embodiment, the vertical bar 4 is connected by angle steel 6 with support plate 3.Specifically, the side of angle steel 6 is logical
Bolt to be crossed to connect with support plate 3, the other side is connect by bolt with vertical bar 4, and it is easy for removal and installation in this way, avoid high-altitude from carrying out
Welding operation.
In the present embodiment, the cross-arm body 1 is set close to the side of shaft tower ontology A there are two foot-operated 7, the foot
It steps on 7 and is equipped with anti-slip part 8；Described foot-operated 7 are at least partly connected with the end of cross-arm body 1, the foot-operated 7 at least portion
Divide and be fixedly connected with the shaft tower ontology A of peripheral hardware, foot-operated 7 free end is arc.Foot-operated 7 stress point is in cross-arm body
On 1 and shaft tower ontology A, therefore stress is relatively good, highly-safe when personnel trample.
In the present embodiment, the cross-arm body 1 is positive six sides perpendicular to the section of the length direction of cross-arm body 1
Shape, the support plate 3 are welded on two inclined-planes on the top of cross-arm body 1, and support plate 3 passes through twin fillet wolt 10 and cross
Ontology 1 is carried on a shoulder pole to be welded to connect.Twin fillet wolt 10 can be improved welding stability, in process, in advance weld cross-arm body 1
Support plate 3 is connected, it is all more convenient when installing metal otter board 2 and handrail in this way.
Free end as cross-arm body 1 commonly used in the art, described is provided with the hanger 9 for hanging insulator chain.
Above-described is only the preferred embodiment of the utility model, all within the scope of the spirit and principles of the utility model
