Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of the transmission tower truss of an embodiment;
Fig. 2 is the structural representation at another visual angle of transmission tower truss of an embodiment.
The specific embodiment
The transmission tower truss of one embodiment, as depicted in figs. 1 and 2, comprises 4 king-posts 100, the first cross bar 200, the first brace 300, head rod 400, the second brace 500 and the second connecting rod 600.The upper end of described king-post 100 is provided with the upper interface being connected with transmission tower, and the lower end of described king-post 100 is provided with the lower interface being connected with base station.Described the first cross bar 200 is perpendicular to described king-post 100, and two ends are connected to the upper end of two adjacent king-posts 100.Described first brace 300 one end are connected in the lower end of described king-post 100, and the other end is connected in the first cross bar 200 middle parts that are connected with described king-post 100.Described head rod 400 is perpendicular to the first brace 300, and one end is connected in described the first brace 300 middle parts, and the other end is connected in king-post 100 upper ends that are connected with described the first brace 300.Described the second brace 500 two ends are connected to the middle part of two adjacent the first cross bars 200.Described second connecting rod 600 one end are connected in described the second brace 500 middle parts, and the other end is connected in the upper end of the nearest king-post 100 of described the second connecting rod 600 of distance.
The design of transmission tower truss should be mated with transmission tower, and transmission tower structure therefore is also determined by transmission tower to a certain extent, as the quantity of the length of the first cross bar 200 and king-post 100 will match with transmission tower.When transmission tower is triangle transmission tower, the quantity of the king-post 100 of transmission tower truss is 3, and when transmission tower is cubic transmission tower, the quantity of the king-post 100 of transmission tower truss is 4.In the present embodiment, take transmission tower as cubic transmission tower be example, therefore the quantity of the king-post 100 of transmission tower truss is designed to 4, accordingly, the quantity of the first cross bar 200, the first brace 300, head rod 400, the second brace 500 and the second connecting rod 600 is respectively 4,8,8,4,4.
Above-mentioned transmission tower truss, comprises king-post 100, the first cross bar 200, the first brace 300, head rod 400, the second brace 500 and the second connecting rod 600.King-post 100, the first cross bar 200 and the first brace 300 form a triangular structure, the first brace 300 is perpendicular to the first brace 300, this triangular structure is divided into two triangular structures, the first brace 300 bend resistance intensity have been strengthened, to strengthen the intensity of king-post 100, and then strengthen the intensity of transmission tower truss vertical direction.Two adjacent the first cross bars 200 and the second brace 500 form another triangular structure, the second connecting rod 600 is perpendicular to the second brace 500, this triangular structure is divided into two triangular structures, the second brace 500 bend resistance intensity have been strengthened, to strengthen the intensity of the first cross bar 200, and then the intensity of enhancing transmission tower truss horizontal direction.After transmission tower is separated with base station, transmission tower truss king-post 100 lower ends and base station are fixed, and transmission tower truss king-post 100 upper ends and transmission tower are fixed, because transmission tower truss has certain height, therefore the height of transmission tower is raised, and exhales accordingly height to be also improved.
Above-mentioned transmission tower trussed construction is simple, and the intensity of vertical direction and horizontal direction is large, and steadiness is strong, on former transmission tower basis, by setting up a transmission tower truss, just can reach the object of rising transmission tower, and cost is lower, short construction period.
In an embodiment, as shown in Figure 2, described transmission tower truss is also provided with the second cross bar 700 therein, and described the second cross bar 700 two ends are connected to two the second adjacent brace 500 middle parts.The second cross bar 700 has further strengthened the second brace 500 bend resistance intensity, to strengthen the intensity of the first cross bar 200, and then better strengthens the intensity of transmission tower truss horizontal direction.
In an embodiment, the structure of described king-post 100, the first cross bar 200 and the first brace 300 is tubular structure therein.King-post 100, the first cross bar 200 and the first brace 300 are main load-bearing pillar, and the load bearing is larger.Identical identical with fineness in the situation that at Material texture, it is large that tubular structure can bear load, so king-post 100, the first cross bar 200 and first brace 300 of tubular structure, can make transmission tower truss more firm.
Therein in an embodiment, as shown in Figure 2, described king-post 100 top and bottom, described the first cross bar 200 two ends and middle part, described the first brace 300 two ends and middle part and described the second brace 500 middle parts are provided with junction plate 800, separable fixing by corresponding junction plate 800 between described king-post 100, the first cross bar 200, the first brace 300, head rod 400, the second brace 500 and the second connecting rod 600.For example, by offering through hole at junction plate 800 and above-mentioned parts, be bolted, change like this parts convenient, be conducive to transmission tower truss to be safeguarded.
In an embodiment, described upper interface and described lower interface are provided with reinforcing rib in the junction of described king-post 100 respectively therein.The upper interface of king-post 100 and the load that lower interface directly bears are very large, and reinforcing rib is set can increase the upper interface of king-post 100 and the intensity of lower interface.
In an embodiment, described king-post 100 is also provided with for climbing of upper and lower transmission tower and follows closely 900 therein.Pa Ding900Wei foot provides origin of force, facilitates the upper and lower transmission tower of personnel, for maintenance and inspection and replacing parts are provided convenience.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
