Description
Technical field
The utility model belongs to electrical equipment technical field, relates to electric wire cross-arm, especially a kind of reinforcement structure electric wire cross-arm.
Background technology
Electric wire cross-arm is typically mounted at electric pole top, has porcelain vase above, is used for supporting trolley wire.Cross-arm is part important in shaft tower, and it is used for installing insulator and gold utensil, to support wire, lightning conducter, and is allowed to the safe distance certain by regulation holding.At present the end of overhead distribution the most at home and wire break and generally use common double cross-arm as attachment means at connection, a metastable angle space can be there is between cross-arm and electric pole, it is especially susceptible to various birds and builds nest, if tramp metal silk or Bird's Nest humidity conduction cause short circuit and breaking accident in Bird's Nest, cause power supply unit to damage and large-area power-cuts, bring massive losses to power system and users.
The utility model patent of application number 201420173482.6, open a kind of self-regulation cross-arm, including the main cross-arm that insulate, insulation pair cross-arm, the main cross-arm that insulate is made up of front cross-arm, rear cross-arm, front cross-arm is arranged on to be fixed on the welded plate being connected with shaft, rear cross-arm and front cross-arm are hinged by rotating shaft, equipped with removable thread-laying device on rear cross-arm, the secondary cross-arm one end of insulation is fixed on rear cross-arm, the other end is hinged with the hinged seat being fixed on shaft by rotating shaft, and front cross-arm, rear cross-arm, insulation pair cross-arm and shaft form triangle；Wire tension by Equilibrium cross-arm two ends is poor, eliminates the gold utensils such as insulator, reduces cost, it is to avoid line-outage contingency occurs, and ensures power grid security.
Self-regulation cross-arm patented product disclosed above, compared with tradition cross-arm structure, there is the advantage saved material, reduce cost, but its structure does not improve product structure stability, and yet suffer from fixed space after An Zhuaning between cross-arm and electric pole, the phenomenons such as birds nesting at cross-arm cannot be avoided, therefore, cross-arm structure need to be designed, solve product stability and prevent birds from nesting problem.
Utility model content
The utility model is for solving the deficiencies in the prior art, it is provided that a kind of reinforcement structure electric wire cross-arm, to realize improving cross-arm product stability, and the problem such as prevent that birds from nesting at cross-arm.
The technical solution of the utility model is as follows:
A kind of reinforcement structure electric wire cross-arm, is made up of vertical reinforcing plate, U-bolt installing hole, horizontal reinforcing plates, electric pole holes for clamping, rack mounting apertures, clamping auricle and fastener hole.Vertically reinforcing plate and horizontal reinforcing plates are overall direct organization, and U-bolt mounting hole site is on vertical reinforcing plate face, and electric pole holes for clamping, rack mounting apertures and clamping auricle are positioned on horizontal reinforcing plates face, and fastener hole is positioned on clamping auricle.
Vertically reinforcing plate is inverted triangle panel construction, intermediate symmetrical position design U-bolt installing hole, and triangular panels, as a kind of reinforcement structure, can strengthen stability and the extraneous adverse circumstances ability of opposing of electric wire cross-arm.
A total of four of U-bolt installing hole, horizontal direction two is one group, and vertical direction has two groups.Using U-bolt to stride across electric pole direct, bolt head stretches out from the U-bolt installing hole of vertical reinforcing plate, installs nut and can be fixed by U-bolt, thus the U-bolt realized between electric wire cross-arm and electric pole is connected.
After electric pole is connected with vertical reinforcing plate by U-bolt, the termination of electric pole is stretched out from the electric pole holes for clamping being positioned at horizontal reinforcing plates.Electric pole holes for clamping is open circles pore structure, and circular hole opening both sides separately design clamping auricle.Electric wire cross-arm is fixed by upper and lower two groups of U-bolts with electric pole, strengthens connective stability.
The outside end face of two panels clamping auricle is all provided with counting fastener hole, and symmetrical fastener hole can make to be connected with.After using bolt fastening, two panels clamping auricle moves to centre, drives electric pole holes for clamping to shrink, so that the electric pole through electric pole holes for clamping is held tightly, it is achieved horizontal reinforcing plates is fixing with electric pole.
Rack mounting apertures is positioned at horizontal reinforcing plates and vertical reinforcing plate junction, and this position intensity is high, rigidity is stably suitable to install all kinds of support.Rack mounting apertures 6 altogether, symmetrical.
Effect of the present utility model and benefit be:
(1) this reinforcement structure electric wire cross-arm, utilizes triangular vertical reinforcing plate to improve stability and the extraneous adverse circumstances ability of opposing；
(2) two groups of U-bolts improve the bonding strength of electric wire cross-arm and electric pole；
(3) horizontal reinforcing plates makes electric wire cross-arm not possess fixing dead angle, it is to avoid nesting of birds；
(4) horizontal reinforcing plates has electric pole clamping device, improves the connective stability of electric wire cross-arm and electric pole further.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
A kind of reinforcement structure electric wire cross-arm, as shown in Figure of description 1-2, is made up of vertical reinforcing plate 1, U-bolt installing hole 2, horizontal reinforcing plates 3, electric pole holes for clamping 4, rack mounting apertures 5, clamping auricle 6 and fastener hole 7.Vertically reinforcing plate 1 and horizontal reinforcing plates 3 are overall direct organization, and U-bolt installing hole 2 is positioned in vertical reinforcing plate 1, and electric pole holes for clamping 4, rack mounting apertures 5 and clamping auricle 6 are positioned on horizontal reinforcing plates 3, and fastener hole 7 is positioned on clamping auricle 6.
Embodiment
Electric pole passes electric pole holes for clamping 4, uses U-bolt to stride across electric pole and stretches out from U-bolt installing hole 2, and use nut to be locked U-bolt, it is achieved vertically reinforcing plate 1 is adjacent to and electric pole.
Use plain bolt through fastener hole 7, and fasten, move clamping auricle 6 at two to centre, thus realize electric pole holes for clamping 4 and hold the electric pole extended there through tightly.
At 6, rack mounting apertures 5 is respectively mounted corresponding cross-arm support, is fixed electric wire.
