Abstract
The utility model discloses an electric steel pipe tower, comprising a main line cross arm and branch line cross arms, which are connected to a tower body. The main line cross arm is connected to cross arms for hanging branch leads. The main line cross arm is provided with a lead hanging point and two pull bard connected to the tower body. Two ends of the branch line cross arm are respectively provided with a lead hanging point. The specially-produced cross arm of an electric tower is advantageous in that the structure is simple and processing is easy; the weight of the tower is reduced and production cost is decreased; the installation is more convenient, and the difficulty of hanging wires on branches of a high-voltage power transmission steel pipe tower can be well resolved.
Description
Technical field
The utility model relates to a kind of electric power steel pipe shaft tower cross-arm.
Background technology
At present; The steel pipe shaft tower is widely used in and is used for the electric power conveying in the transmission line of electricity; The steel pipe shaft tower of voltage levels, layering is provided with ground wire cross-arm and lead cross-arm usually, owing to receive the restriction of this structure; Shaft tower that need to hang offset can only add multilayer branch cross-arm on shaft tower, cause shaft tower height superelevation or do not match with the iron tower height of whole piece circuit.And in line design, often needing design to hang the steel pipe shaft tower of branch line, superelevation or do not match with the iron tower height of whole piece circuit has restricted the development of steel pipe shaft tower.In addition, the steel pipe shaft tower of said structure is because the cross-arm number of plies is more, and the cross-arm direction is complicated, makes trouble, the production cycle is long, and inconvenient installation.Increasing branch's cross-arm needs the layering setting, has increased the height of shaft tower, and has increased the weight of the weight of shaft tower, and the Lifting Method in Pole Tower Integral Hoisting manufacturing cost is also higher.
Summary of the invention
The utility model technical problem to be solved is: a kind of electric power steel pipe shaft tower cross-arm is provided; Well solve the difficult problem of high voltage power transmission steel pipe shaft tower branch hanging wire, simple, the easy processing of implementation structure alleviates shaft tower weight; Reduce production costs purpose easier for installation.
For solving the problems of the technologies described above; The technical scheme of the utility model is: electric power steel pipe shaft tower cross-arm; Comprise the main line cross-arm that is connected with body of the tower and branch line cross-arm connected vertically in the outer end of main line cross-arm; Said main line cross-arm is provided with the lead hanging point, at the two ends of said branch line cross-arm the lead hanging point is set respectively.
As a kind of optimized technical scheme, said main line cross-arm is provided with several handrails and is connected with body of the tower with two pull bars.
As a kind of optimized technical scheme, it is the polygon Taper Pipe that said cross-arm adopts the cross section.
After having adopted technique scheme; The beneficial effect of the utility model is: 1. because the cross-arm of the utility model comprises main line cross-arm and the branch line cross-arm that is connected; Outer end at the main line cross-arm vertically connects the branch line cross-arm, is respectively arranged with a lead hanging point at the two ends of branch line cross-arm, and a branch line cross-arm can be hung two offsets; A double loop shaft tower needs three layer conductor cross-arms; If add the double loop branch line, then need six layer conductor cross-arms, adopt three layers of this special cross-arms can solve two two hanging wires that return branched line of main line that return.Therefore, the utility model can well solve branch's hanging wire problem of high voltage steel pipe shaft tower, reduces the shaft tower height, satisfies the hanging wire requirement of transmission line of electricity, makes that high voltage branch steel pipe pole tower weight amount is lighter, profile is more attractive in appearance.2. the utility model just can be realized setting up of two branch lines of a main line on a cross-arm, and the shaft tower that the offset cross-arm is set with traditional batch is compared, and structure is simpler; Reduced difficulty of processing; Make easier for installationly, and alleviated shaft tower weight, reduced cost of production.3. because the cross-arm of the utility model adopts cross-arm to connect the mode of cross-arm, the polygon Taper Pipe is adopted in the cross section, has reduced the shaft tower height; Can obviously reduce body of the tower blast, good stability; The foundation area that reduces shaft tower can be arranged, reduce and take up an area of, its load-carrying properties are good.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the Facad structure sketch map of the utility model embodiment:
Fig. 2 is the plan structure sketch map of the utility model embodiment:
Among the figure: 1. body of the tower, 2. main line cross-arm, 3. branch line cross-arm, 4. handrail, 5. pull bar, 6. hanging point
The specific embodiment
As shown in Figure 1, a kind of electric power steel pipe shaft tower cross-arm comprises two handrails 4 that branch line cross-arm 3 is connected with the main line cross-arm 2 that is attached thereto, with body of the tower 1, and said main line cross-arm 2 employing cross sections are polygonal Taper Pipe.
Said cross-arm comprises main line cross-arm 2 and two pull bars 5, the branch line cross-arm 3 that are connected with body of the tower, is T font syndeton.
Be provided with hanging point 6 in the end of said main line cross-arm 2, be used to hang the main line lead.Centre and two ends at said branch line cross-arm 3 are respectively arranged with lead hanging point 6, and lead hanging point 6 approximate being on the same horizontal plane can be satisfied the horizontal hanging wire requirement of transmission line of electricity.
In order to install and to overhaul conveniently, on said main line cross-arm 2, also be provided with several handrails 4.
