Technical staff by practice it is any it is appropriate in a manner of differently apply representational basis of the present utility model, including using here
The feature that disclosed various features and combination may not disclosed clearly here.
Embodiment one：
Please also refer to Fig. 1-Fig. 5.As shown in figure 1, compound cross-arm 10 is fixed on the body of rod 12 of power transmission rod 11, this is compound
Cross-arm 10 includes：Plug 101, the insulating barrier 102 being coated on plug 101 and sleeve mechanism 103；Sleeve mechanism 103 includes set
Cylinder 1031 and cross-arm connecting plate 1032, sleeve 1031 are socketed on plug 101, and cross-arm connecting plate 1032 is fixed in sleeve 1031
Side and for being attached with the body of rod 12.
The sleeve mechanism 103 set on plug 101, as shown in Fig. 2 the sleeve mechanism 103 includes sleeve 1031 and horizontal stroke
Connecting plate 1032 is carried on a shoulder pole, sleeve 1031 is usually the hollow tube-shape of both ends open, and cross-arm connecting plate 1032 is optional with sleeve 1,031 1
It is body formed, or cross-arm connecting plate 1032 is fixed on sleeve 1031 towards the one of the body of rod 12 by way of mucilage binding or welding
Side, other fixed mechanism can be set on the body of rod 12 and be connected with cross-arm connecting plate 1032, plug 101 is socketed on using sleeve 1031
On realize the connection of sleeve mechanism 103 and compound cross-arm 10, realize the connection with the body of rod 12 using cross-arm connecting plate 1032, can be with
Find out, being fixedly connected without being punched on compound cross-arm 10 for this mode, avoid the influence to the compound mechanical property of cross-arm 10.
Specifically, plug 101 is the main composition important document of compound cross-arm 10, and plug 101 is one along longitudinally extension
Body structure, typically by pultrusion after glass fibre and resin mixing, it is of course also possible to after by glass fibre and resin mixing
Compression molding, or other technological formings are used, this is not limited.The optional polyurethane of resin, epoxy resin or vinyl tree
Fat etc..
Plug 101 can be solid, or at least have the body of a chamber, and the cross sectional shape of plug 101 is optional
Circular, polygon or I-shaped, can be selected as needed in practical engineering application.The plug 101 of the present embodiment is solid
Circular structure.
Plug 101 is chronically exposed in air, easily by the corrosion of various natural causes such as light, electricity, water, acid etc., is made
Phenomena such as intensity decreases being produced into surface aging, therefore usually require to handle the surface of plug 101, conventional way is
In the Surface coating fixed insulation layer 102 of plug 101, it can further improve the insulating properties of plug 101 and/or play etch-proof
Effect.
Insulating barrier 102 is chosen as full skirt 1021 and the sheath 1022 extended on plug 101, or is directly to be coated on core
The sheath 1022 on the surface of rod 101, full skirt 1021 or sheath 1022 can use the silicon rubber of molding sulfidization molding to be made, or adopt
It is made of the silicon rubber of integral injection molding, the insulating barrier 102 has good hydrophobicity and ageing resistance, service life height.
But the insulating barrier 102 does not have the ability of bearing load, if load is acted directly on insulating barrier 102, hold
It is easily caused the cracking of insulating barrier 102 or comes off, so that plug 101 exposes in atmosphere, intensity decreases, under mechanical property
Drop.
Therefore, the compound cross-arm 10 of the present embodiment, a sleeve mechanism is preset at the position that plug 101 is connected with the body of rod 12
103, sleeve mechanism 103 is usually metal material, is chosen as steel, sleeve 1031 is socketed on plug 101, when compound cross-arm 10
When on power transmission rod 11, fixed load is applied directly on sleeve 1031 between the two, without being consequently exerted at plug 101
Or on insulating barrier 102, plug 101 itself will not deform, insulating barrier 102 will not also wear because of long-term stress, insulation
The plugs 101 of the cladding of layer 102 are not exposed in air, avoid corrosion of the external environment condition to plug 101, and sleeve mechanism
103 have enough intensity, and itself will not be damaged because of long-term stress, so as to ensure that the mechanical property of compound cross-arm 10
Energy.
The production stage of the plug 101 of above-mentioned compound cross-arm 10, sleeve mechanism 103 and insulating barrier 102 is：
A) it is integrally formed plug 101 by pultrude process；
B) sleeve 1031 is made to be socketed in the middle part of plug 101, the inner wall shape of sleeve 1031 by way of mucilage binding or crimping
It is adapted with the cross section of plug 101, whole outer peripheral faces at the middle part of 1031 core rod of sleeve 101；
C) in the both sides of sleeve 1031 difference integrated injection molding full skirt 1021 and sheath 1022, full skirt 1021 and sheath
1022 injection can avoid the region at the hanging wire gold utensil of end, and sleeve 1031 is provided with flange 1033, and flange 1033 is provided with
Beneficial to the sealed connection between sleeve 1031 and sheath 1022；
It should be noted that for the plug 101 of end regions, extension can be made before full skirt 1021 and sheath 1022 are molded
Line gold utensil is first fixed in end by way of mucilage binding or crimping, then on the plug 101 at except sleeve 1031 and hanging wire gold utensil
It is molded.The setting energy meet demand of hanging wire gold utensil or pin insulator, does not do specific discussion herein.
By the compound cross-arm of above-mentioned production stage, sleeve 1031 coats the outer peripheral face for being socketed in the middle part of plug 101, full skirt
1021 and whole outer peripheral faces in other regions of the core rod 101 of sheath 1022 in addition to middle part and end, sleeve 1031 and full skirt
It is tightly connected between 1021 and sheath 1022 so that plug 101 is covered by sleeve 1031 and sheath 1022, from external rings
The corrosion in border.
As shown in figure 3, Fig. 3 is the structural representation of power transmission rod 11, the power transmission rod 11 includes above-mentioned compound cross-arm 10 and bar
Body fixture 13, body of rod fixture 13 are used to compound cross-arm 10 being fixed on the body of rod 12.
