Abstract
The invention relates to a pole provided with a steel-aluminum combined standard knot for transmission lines tower erecting construction. The upper ends and lower ends of four primary steel bars of the standard knot are connected with one connecting flange respectively to form the frame of the standard knot, and end head connected angle iron is welded at the seam of a connection board and the primary steel bar. A slanting secondary steel bar is riveted crosswise on the primary steel bar through rivets, and an intermediate secondary steel bar is connected with the middle part of the primary steel through the rivets. The material of the primary steel bar is the angle iron, while the material of the secondary steel adopts the angle aluminum. Due to the combination of the steel-aluminum standard knot, the pole not only meets the requirements of strength and structure, but also greatly reduces manpower and material resources for transportation and erection of the pole; moreover, the pole is convenient to transport and use, reduces the cost, and has the remarkable effect when the pole is used for the transmission lines tower erecting construction in special environments such as mountain areas with the inconvenient traffic and difficult operation.
Description
Technical field
The present invention relates to the transmission line construction technical field, specifically relate to a kind of pole that is used for the iron tower of power transmission line vertical construction with steel-aluminium composite type standard nodes.
Background technology
At present, domestic transmission line construction iron tower vertical construction is identical material with pole standard knot master's material and auxilliary material, and have steel standard knot and the aluminum standard generally used save.Steel standard knot weight is heavier, but rigidity is big, good stability; Aluminum standard joint weight is lighter, but rigidity is little, poor stability.The power transmission sequence construction is frequent at mountain construction with pole, must alleviate its weight as far as possible, steel standard knot weight is bigger, and aluminum standard joint cross section is bigger, waste time and energy in transportation and construction, all steel or full aluminium pole all can not satisfy the demand under the specific execution conditions preferably.
Summary of the invention
In order to overcome above-mentioned defective, the object of the present invention is to provide a kind of in light weight, intensity is high, transportation, the pole with steel-aluminium composite type standard nodes easy to use.
For achieving the above object, the present invention takes following technical scheme:
A kind of pole with steel-aluminium composite type standard nodes, this pole comprises the top arm-tie, the upper end joint, standard knot, lower end joint and bottom arm-tie, on the arm-tie of bottom, be connected with the lower end joint, the top of lower end joint is connected with standard knot, the top of standard knot is connected with the upper end joint, the top of upper end joint is connected with the top arm-tie, connect by connecting bolt between each standard knot, wherein said standard knot comprises main material, tiltedly auxilliary material and middle auxilliary material, on the described main material, the lower end respectively is connected with the framework that an adpting flange constitutes this standard knot, tiltedly auxilliary material passes through the rivet cross rivet(t)ing on main material, middle auxilliary material is connected with the middle part of main material by rivet, and described main material adopts angle steel, and tiltedly auxilliary material and middle auxilliary material adopt angle aluminium, the total length of described standard knot accounts for 70% of pole total length, and described upper end joint and lower end joint respectively account for 15% of pole total length.
Described adpting flange is made of junction plate and connecting angle, is welded with four termination connecting angles between four junction plates respectively.
Beneficial effect of the present invention is:
1, adopted the pole of steel-aluminium composite type standard nodes, with equal specification, have all steel standard knot pole and compare, weight can alleviate about 10%; Compare with equal specification, pole with full aluminium standard knot, intensity and stability improve greatly.This compound mode, promptly satisfy intensity, stability and topology requirement, significantly reduce pole transportation and group manpower and materials immediately again, transportation, easy to use, particularly be used for the iron tower of power transmission line vertical construction in the particular surroundings of the operating difficultiess of having inconvenient traffic such as mountain area, effect is particularly remarkable.
2, adopt the welding of junction plate and connecting angle to form the structure of adpting flange, the intensity of having strengthened pole of the present invention is with stable, and bearing is better.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention;
Fig. 2 is I portion (standard knot) enlarged drawing among Fig. 1;
Fig. 3 is the decomposing schematic representation of standard knot;
Fig. 4 is the schematic diagram of adpting flange in the standard knot;
Wherein, 1-top arm-tie, 2-upper end joint, 3-standard knot, 4-connecting bolt, 5-lower end joint, 6-bottom arm-tie, the tiltedly auxilliary material of 7-junction plate, 8-termination connecting angle, 9-master's material, 10-, auxilliary material in the middle of the 11-, 12-rivet.
The specific embodiment
As shown in Figure 1, this pole comprises top arm-tie 1, upper end joint 2, standard knot 3, lower end joint 5 and bottom arm-tie 6, on bottom arm-tie 6, be connected with lower end joint 5, the top of lower end joint is connected with standard knot 3, the top of standard knot is connected with upper end joint 2, the top of upper end joint is connected with top arm-tie 1, connects by connecting bolt 4 between each standard knot 3.
As Fig. 2, shown in Figure 3, the framework of this standard knot 3 is made of four main materials 9 and two adpting flanges, the upper end of four main materials is connected an adpting flange upper and lower end and is connected on another adpting flange, on main material, middle auxilliary material 11 is connected with the middle part of main material by rivet 12 tiltedly auxilliary material 10 by rivet 12 cross rivet(t)ings.As shown in Figure 4, adpting flange is made of junction plate 7 and termination connecting angle 8, is welded with four termination connecting angles 8 between four junction plates 7 respectively.
Wherein, main material 9 adopts angle steel, and tiltedly auxilliary material 10 and middle auxilliary material 11 adopt angle aluminium, and the pole weight of this kind collocation can alleviate about 10%, and integral matching is reasonable, strengthens the bulk strength and stability of pole, is more suitable for using in the area of operating difficultiess such as mountain area.
The total length of pole standard knot 3 accounts for about 70% of pole total length, and upper end joint 2 and lower end joint 5 respectively account for about 15% of pole total length, adopt the pole more reasonable stress of this kind ratio.
In use, the top of top arm-tie 1 is connected with tackle pulley, the lifted weight thing links to each other with tackle pulley on being fixed on top arm-tie 1 by hoisting wirerope, also be provided with on the top arm-tie 1 simultaneously and be used to strain and fixedly 4 groups of backguys of pole, 4 groups of backguys be connected respectively on 4 groups of earth anchors or 4 side master materials of iron tower on.Hoisting wirerope on the assembly pulley turns to angle mill or other driving mechanism on ground to reach the purpose that promotes weight by angle pulley.
When group is made portion's iron tower, the bottom arm-tie 6 of pole can be directly fixed on ground; When group was found the top iron tower, lifting altitude was not enough, 4 groups of backguys then need be set on bottom arm-tie 6 be used for pole is fixed on iron tower on iron tower main material, with realization pole was suspended on the iron tower and used.
