Abstract
The utility model provides a through type steel pipe pole cross arm connection structure and belongs to the field of electric power steel pipe poles. The through type steel pipe pole cross arm connection structure overcomes the defect that an existing structure is high in manufacturing cost, large in welding amount, centralized in stress concentration and the like. The technical scheme of the through type steel pipe pole cross arm connection structure is that the through type steel pipe pole cross arm connection structure comprises a pole body and two cross arms perpendicular to the pole body, through holes are formed in the pole body in the horizontal direction, the cross arms penetrate the through holes to be connected with main pipes, cross arm flanges are fixed at two ends of a cross arm connection main pipe, a cross arm flange is fixed at one end of each cross arm, and the cross arm flanges on the cross arms are fixed with the cross arm flanges of the cross arm connection main pipe in a butting mode. The through type steel pipe pole cross arm connection structure has the advantages of being simple in cross arm seat member machining process, small in welding work quantity and capable of reducing process difficulty effectively, reducing production cost, and saving human and material resources substantially.
Description
Technical field
The utility model relates to a kind of electric power steel pipe pole, is specifically related to the syndeton of electric power steel pipe pole cross-arm and the body of rod.
Background technology
In economy flourishing today day by day, be widely used in electric line, common name electric power steel pipe pole in the industry with the bend steel pipe pole of processing of steel plate.The existing power steel pipe pole as depicted in figs. 1 and 2, mainly comprises the body of rod 6 and cross-arm 1, and the effect of the body of rod 1 is for lead wire and earth wire is risen to certain altitude, in order to keep certain safe distance with ground and ground structure; The effect of cross-arm 1 is that lead wire and earth wire and the body of rod are supported certain distance, guarantees the safe distance of lead wire and earth wire and the body of rod.The body of rod 6 is connected by cross-arm flange 2 with cross-arm 1, wherein on the body of rod 6 Connection Block 3 is set, and Connection Block 3 generally is after being bent into the tubulose of regular polygon with steel plate, is welded on the outer wall of the body of rod 1; Two cross-arm flanges 2 are separately fixed on Connection Block 3 and the cross-arm 1, connect by bolt between the cross-arm flange 2.
When cross-arm 1 was subjected to the tension force of lead wire and earth wire or gravity big, cross-arm 1 was traditionally arranged to be tubulose, to satisfy force request.And the superposed body of rod 6 wall thickness are often thinner, and lead wire and earth wire is delivered to extrusion stress on the Connection Block 3 by cross-arm 1, shown in Fig. 2 direction of arrow, very easily cause the body of rod 6 distortion at Connection Block 3 places.Therefore generally set up annular stiffening rib 4 at Connection Block 3 places, pulling force or the pressure that is delivered on the body of rod 6 is disperseed, to avoid 6 distortion of Connection Block 3 place's bodies of rod.This structure is brought following shortcoming: 1, cost of manufacture height, Connection Block 3 often need bending after the steel plate setting-out, group to, welding; 2, welding capacity is big, and the annular stiffening rib 4 weld seam length overalls of increase are bigger, and needs welding quality preferably; 3, Connection Block 3 place's welding stresses are concentrated etc.
Summary of the invention
[0003] in order to overcome the above-mentioned defective that the known technology field exists, the purpose of this utility model is to provide the through steel pipe pole cross-arm syndeton that a kind of technology is simple, welding capacity is little, cost is low.
The through steel pipe pole cross-arm syndeton that the utility model provides, it comprises the body of rod and the two piece cross-arms vertical with the body of rod, wherein the body of rod laterally has through hole, run through cross-arm in the through hole and connect the person in charge, cross-arm connects person in charge two ends fixedly the cross-arm flange, every cross-arm one end fixedly has the cross-arm flange, and the cross-arm flange on the cross-arm is connected the cross-arm flange butt joint of being responsible for cross-arm fixing.
The through steel pipe pole cross-arm seat that the utility model provides, its beneficial effect is that cross-arm seat member processing technology is simple, the welding engineering amount is less, can reduce technology difficulty effectively, reduces cost of production, has significantly saved human and material resources.
In order to reach better effect, when cross-arm is longer or when heavier, be provided with the flange stiffening rib between the described cross-arm connection person in charge and cross-arm flange, described cross-arm and the cross-arm flange, to increase bonding strength.
Description of drawings
Fig. 1 is the front view of the existing steel pipe pole body of rod and cross-arm syndeton.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the front view of steel pipe pole cross-arm syndeton described in the utility model.
Fig. 4 is the vertical view of Fig. 3.
Mark among the figure:
1. cross-arm; 2. cross-arm flange; 3. Connection Block; 4. annular stiffening rib; 5. cross-arm connects the person in charge; 6. the body of rod.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the steel pipe pole cross-arm syndeton that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 3 and Fig. 4, the steel pipe pole cross-arm syndeton of present embodiment comprises that cross-arm 1, cross-arm flange 2, cross-arm connect the person in charge 5.
Perforate on the body of rod 6 is responsible for 5 with the cross-arm connection and is inserted and weld with the body of rod 6.Cross-arm flange 2, stiffening rib are fixed on cross-arm by welding manner and connect on the person in charge 5.Cross-arm connects the person in charge 5 can adopt conventional steel plate wrap direction processing, also can adopt the fished pipe intercepting of close specification.When adopting the latter, steel pipe thickness is with tubulose cross-arm steel plate thickness, and external diameter should be reference with the diagonal-size of tubulose cross-arm root regular polygon, and for example: tubulose cross-arm root diagonal-size is 165MM, steel plate thickness is 6MM, and then the cross-arm connection person in charge 5 specification should be the steel pipe of Φ 168*6.The cross-arm of this structure connects the person in charge 5 and has the little advantage of processing capacity, only needs get final product from the intercepting of finished product seamless steel pipe.
Stressed from the body of rod, in the existing structure, what the body of rod 6 tube walls at Connection Block 3 places were subjected to is the extrusion stress of more complicated, if body of rod tube wall is thinner, then must set up annular stiffening rib, it is more loaded down with trivial details to construct.The steel pipe pole cross-arm syndeton that this example provides, what be subjected at body of rod tube wall place is the compressive stress of positive direction, as shown in Figure 4, and this pressure can be delivered to the body of rod uniformly by the contact surface that cross-arm connects the person in charge 5 and the body of rod, thereby avoided setting up the loaded down with trivial details of annular stiffening rib, can reduce technology difficulty, reduce cost of production, save human and material resources.
