The high stable connection connecting ring 6.Described anchor ear 4 is U-shaped groove-like structure, clamping in the U-lag of anchor ear 4
Cross-arm 1 is installed, and utilizes fastening connection piece 3, such as rivet, make cross-arm 1 and anchor ear 4 be fixedly connected into one.
Described cross-arm 1 can be cross section be square column, as it is shown on figure 3, so, snap fit onto at cross-arm 1 and embrace
After the U-lag of hoop 4, it can be ensured that cross-arm 1 will not rotate relative to anchor ear 4, thus ensure anchor ear 4 and cross-arm 1
Between connection reliability；Further, it is processed to form fillet surface 18 respectively in the corner of described cross-arm 1, arranges
Fillet surface 18 is so that cross-arm 1 more easily snaps fit onto the U-lag of anchor ear 4, and guarantees that both put in place in mutual clamping.
Fix between described installing plate 2 and anchor ear 4 and be connected, such as, can weld between described installing plate 2 and anchor ear 4
Mode or riveting method are fixedly connected into " ten " character form structure, and, installing plate 2 is also offered some
Installation through hole 21.
Described cross-arm 1 can be the column using unsaturated polyester (UP) felt to be processed into, it is also possible to be to use alkali-free glass
The column that fiber process becomes, it is also possible to be the unsaturated polyester (UP) carpet veneer and alkali-free glass using unsaturated polyester (UP) felt to be formed
Fibroplastic alkali-free glass fibre layer alternately superposition the layered composite structure consolidated.No matter unsaturated polyester (UP) felt
The cross-arm 1 of material, or the cross-arm 1 of alkali-free glass fibre material, or comprise unsaturated polyester (UP) carpet veneer, alkali-free glass
The fibrolaminar layered composite structure of glass, can make cross-arm 1 goods be compared to traditional steel cross-arm, wooden horizontal stroke
Load goods gentlier, thinner, and there is more preferable weatherability, thus be conducive to improving installation effectiveness and the peace of cross-arm 1
Service life after dress.
As it is shown on figure 3, the layered composite structure that the cross section of described cross-arm 1 is annular, and from internal layer to outer layer successively
It is first unsaturated polyester (UP) carpet veneer the 12, first alkali-free glass fibre layer the 13, second unsaturated polyester (UP) carpet veneer 14.In order to
Improve the mechanical strength of cross-arm 1 further, and advantageously reduce cross-arm 1 degree of disturbing, can be at the second unsaturated polyester (UP) felt
Second alkali-free glass fibre layer 15 of layer 14 outer surface cladding annular, described second alkali-free glass fibre layer 15 is by alkali-free
Glass fibre consolidation molding；The 3rd unsaturated polyester (UP) carpet veneer in the second alkali-free glass fibre layer 15 outer surface cladding annular
16, described 3rd unsaturated polyester (UP) carpet veneer 16 is consolidated molding by unsaturated polyester (UP) felt.It addition, it is unsaturated the described 3rd
Antiaging coatings 17 can also be coated, as the weather resistant coatings of whole cross-arm 1 on the outer surface of polyester carpet veneer 16；
Generally, described antiaging coatings 17 is formed after using aliphatic polyurethane coating certain thickness.Pass through antiaging coatings
17 ageing-resistant, the resistance against ultraviolet and yellowings that cross-arm 1 can be substantially improved, thus the making of cross-arm 1 is greatly improved
Use the life-span.
As it is shown on figure 3, described cross-arm 1 can also be the annular lamellar composite construction of hollow, and, at cross-arm 1
Hollow cavity in can with filled polyurethane formation of foam polyurethane foam packing layer 11, and utilize plastic cement block to horizontal stroke
Carry on a shoulder pole 1 goods and carry out end seals, so can improve the rigidity of cross-arm 1 further.By the cavity at cross-arm 1
Body is internally formed polyurethane foam packing layer 11, so that this composite material cross arm product is same conveniently carry out punching
Time, also will not reduce the mechanical strength of this cross-arm product, meanwhile, also there is auxiliary and lower the effect of cross-arm degree of disturbing.
After described cross-arm 1 uses above-mentioned layered composite structure as shown in Figure 3, become a kind of polyurethane-glass system multiple
Condensation material cross-arm.By laying unsaturated polyester (UP) carpet veneer at interlayer, hoop intensity and the machine that can improve cross-arm 1 add
Work performance, lowers the degree of disturbing of cross-arm 1.It should be noted that described unsaturated polyester (UP) carpet veneer is not limited to above-mentioned
One unsaturated polyester (UP) carpet veneer the 12, second unsaturated polyester (UP) carpet veneer the 14, the 3rd unsaturated polyester (UP) carpet veneer 16, can be according to
Layered composite structure order rule as shown in Figure 3 lays the unsaturated polyester (UP) carpet veneer of multiple structure, such as, 3 layers, 4
Layer, 5 layers, 6 layers, even more multilamellar, so so that cross-arm 1 significantly reduces on degree of disturbing, part specification
Cross-arm product additional Holder Fasteners can not be used i.e. to can be used directly, the cross-arm product of part specification adds simple
Support adnexa just can reach use standard.It is compared to traditional epoxy systems composite material cross arm and unsaturated-resin system
Composite material cross arm, is not only greatly improved the mechanical strength of cross-arm, meanwhile, is reaching equal mechanical strength condition
Under, this cross-arm goods gentlier, thinner, thus easily facilitate transport, install.
Cross-arm mounting structure of the present utility model is applied to overhead transmission line installing rack as shown in Figure 4, Figure 5, its
In shaft tower 7 and installing plate 2 between by fastening connection piece 3, such as rivet, be directly fixedly connected into " ten " word
Shape structure, so that the installation effectiveness of cross-arm 1 is significantly promoted.Wherein, described installing plate 2 uses V-arrangement
Structural slab, the octagon structure that cross sectional shape is hollow of described shaft tower 7, therefore, the V-shaped groove on installing plate 2
Can hold shaft tower 7 tightly, this structure is so that installing plate 2 has certain elasticity, it is ensured that installing plate 2 and shaft tower 7
Between contact good, and make installing plate 2, shaft tower 7 obtain certain interference rejection ability, improve installing plate 2, shaft tower 7
