Abstract

The utility model relates to an electrical tower pole structure, which is made of ten kinds of composite materials such as polyester resin, porcelain cement, glass fiber, etc. The utility model is mainly composed of a rod body, a base of the rod body, a nylon plastic rivet, a stainless steel clamp, an insulator, etc. Because the material which has little possibility to be rusted is used, the nylon plastic rivet and the stainless steel clamp are used in the assembly of the top end of the pole tower and other fittings, bolts and nuts are not selected, and the aims of low cost and no maintenance are realized.

Description

A kind of non-maintaining electric force pole tower of making of composite material

The utility model relates to a kind of electric force pole tower of making of composite material, and especially a kind of effective service life is long, light weight, the electric force pole tower that non-bolt is non-maintaining.

At present, known electric force pole tower mainly contains cement pole, iron tower bar and rod, but, electric power is eliminated gradually with rod, fracture is arranged through record when being applied to the cement pole on defeated modified line road as great majority, and cement pole and iron tower bar owing to self heavy must reason, transportation is higher with mounting cost, owing in installation, used many bolts, determined it in use to need to safeguard on time, wasted many manpower, material resources and financial resources.

The purpose of this utility model just provides the non-maintaining electric power line pole tower of a kind of non-bolt, it not only can be used for all electric force pole towers such as high-tension line shaft tower, light pole, cross-arm, lightning-arrest bar, microwave transmission tower, also can be used for all required frameworks of other engineering simultaneously.

The purpose of this utility model is achieved in that is using mylar, the porcelain powder, main rod body that composite materials such as glass fiber are made and cross-arm constitute on the framework, and cross-arm passes the main rod body axle center, fixes with the nylon plastic(s) rivet, live rivet with the stainless steel mounting board then, prevent that it from deviating from, insulator is fixed with the nylon plastic(s) rivet equally, because material therefor all is difficult for getting rusty, simultaneously also not as the easily loosening accessory of bolt, so this product need not to safeguard on time.The utility model is compared with existing product, except that tensile strength, compressive strength, moment of flexure, amount of deflection, shaft moment of torsion reach the necessary parameter of electric power bar, also possess following advantage: (1) is in light weight, only be 1/3 of iron tower bar and cement pole, can save the waste that freight (2) raw material do not have offal; (3) mounting cost is lower, and only be 1/5 of iron tower bar man-hour; (4) the comparable iron tower height of the same type of compact design falls low 20% and do not reduce the use effect; (5) can reduce the electromagnetic field intensity of iron tower; (6) can be in preparation raw material directly color matching and needn't brushing paint arbitrarily; (7) raw material 70% are the inorganic material glass fabric, so service life is long, can use 80 years, and cement pole only use 8-15; (8) the maintenance minimum of Yao Qiuing needn't be cleaned maintenance every year; (9) Chinese People's Anti-Japanese Military and Political College's gas, salt fog, soda acid, moisture-proof are stronger than cement pole and iron tower bar, and can anti-aging, fire-retardant, insulation; Be not only applicable to the inland, the regeneration product of coastal especially and salt fog prone areas; (10) cost of raw material and cost of production only are 1/3 of iron towers.

Below in conjunction with accompanying drawing and embodiment the utility model is further specified:

Fig. 1 is the section assembly drawing of first embodiment of the utility model.

Fig. 2 is the internal organs view of Fig. 1.

Fig. 3 is an A-A section assembly drawing among Fig. 1.

Fig. 4 is a B-B section assembly drawing among Fig. 1.

Fig. 5 is second embodiment of the present utility model-----two bridge structure assembling schematic diagrames.

Among the figure 1, anchoring bolt 2, body of rod base 3, base flange plate 4, ditch nut 5, backguy 6, the body of rod 7, insulator 8, nylon plastic(s) rivet 9, cross-arm 10, nylon plastic(s) rivet 11, backguy flange 12, nylon plastic(s) rivet 13, body of rod bulge loop 14, stainless steel folder 15, cross-arm section Figure 16, nylon plastic(s) rivet 17, stainless steel steel folder 18, pull bar 19, cross-arm 20, cross-arm 21, rivet hole 22, nylon plastic(s) rivet 23, rivet hole

In Fig. 1, anchoring bolt (1) compresses body of rod base (2) with flange (3), and backguy flange (11) circle is pressed on the bulge loop (13) of the body of rod (6), and it is solid on concrete the body of rod (6) with backguy (5) to use nylon plastic(s) rivet (12).Cross-arm (9) is fixed on the body of rod (6) upper end with nylon plastic(s) rivet (10), and is tightened with anti-skidding by stainless steel folder (14).Cross-arm is the amount doesn't matter as required, concrete assembling is shown in Figure 3 as the A-A section, insulator (7) by nylon plastic(s) rivet (8) riveting in cross-arm (9) outer end, concrete shown in Figure 4 as the B-B tangent plane, block nylon plastic(s) rivet (8) other end in case outer cunning by stainless steel folder (17).

Second embodiment as shown in Figure 5, two bridge structures are except that using cross-arm (19) and cross-arm (20) is connected, also connecting two pull bars (18), in the hope of reaching firm effect, the cross-arm of two bridge structures is identical with Fig. 3, Fig. 4 respectively with the assembling of body of rod assembling, cross-arm and insulator.

Still all easily do not get rusty in many bridges structure upper end in single pole framework upper end like this accessory and raw material adopt nylon plastic(s) rivet and stainless steel folder to replace the bolt and nut assembling again relatively firmly and can not come off and skid off, so reached non-maintaining purpose.
