The insulating adhesive layer (2) is connected with the inner surface of the insulating layer (1). The isolation layer (6) covers the outer surface of the insulating adhesive layer (2). A new polymer material with good insulating performance is used as the insulating layer, and the insulating adhesive layer (2) with good insulating and adhesive performance makes double-layer covers for the load-bearing rope, which enhances the work efficiency greatly. The utility model has the advantages of simple art and work and labor saving, so as to provide double-layer protection for the load-bearing rope.
Description
Technical field
The utility model relates to a kind of electrified railway device, particularly a kind of opening tubular type catenary insulation protective jacket.
Background technology
Existing electrification railway contact net usually in the tunnel, portal, public affairs stride the inferior place of railway bridge, because existing catenary is to expose in air to use, its can because leak, icicle, branch and other foreign material cause catenary ground connection to open circuit, when situation is serious, will blow catenary and cause the net that collapses, bring loss to railway transportation.For preventing that the problems referred to above from taking place, adopt the method for on catenary, twining the isolating shrinkable band to protect at present usually, but this method technology loaded down with trivial details, waste time and energy, especially be subjected to the restriction of electrified skylight time, its effect is very low.
Summary of the invention
The purpose of this utility model provides a kind of opening tubular type catenary insulation protective jacket; it can prevent that catenary from exposing in air and use; prevent ozone oxidation; waterproof, anti-short circuit; anti-soda acid corrodes; it can be increased work efficiency greatly, and its technology is simple, save labor, and reaches the double shielding to the catenary cable.
The purpose of this utility model is to realize like this; design a kind of opening tubular type catenary insulation protective jacket; it is characterized in that: which comprises at least insulating barrier 1, insulation adhesive layer 2, isolation layer 6, insulating barrier 1 inside face is connected with insulation adhesive layer 2, and insulation adhesive layer 2 outside face are coated with isolation layer 6.
The developed surface of described insulation protective jacket is a rectangle structure, and its insulation adhesive layer 2 length grow 0.5～2cm than the length of insulating barrier 1; The width of insulation adhesive layer 2 grows 1～4cm than the width of insulating barrier 1; The thickness of insulation adhesive layer 2 is identical with the thickness of insulating barrier 1.
The length of described insulating barrier 1 is chosen as 500～1500cm, and width is chosen as 20～35cm, and thickness is chosen as 0.15～0.35cm.
Described isolation layer 6 sizes are more than or equal to insulation adhesive layer 2 length and width dimensions.
Described developed surface is a rectangular insulation protective jacket cross section drum twist.
Characteristics of the present utility model are: opening tubular type catenary insulation protective jacket is as insulating protective layer by characteristics such as good insulating power of novel high polymer material and weather resistances; be aided with the strong liner tack coat of insulating power and adhesive performance; the closely knit layer by layer catenary cable outside that is wrapped in; make it to become one; preventing that catenary from exposing in air uses; avoid leaking, icicle, branch and other foreign material cause catenary ground connection to open circuit; be unlikely to blow catenary and cause the net that collapses; bring loss to railway transportation, catenary is played double protection.Can further specify the beneficial effects of the utility model by following table.

Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the example structure scheme drawing;
Fig. 2 is an embodiment deployed configuration scheme drawing;
Fig. 3 is an embodiment running condition structural representation.
Among the figure: 1, insulating barrier; 2, insulation adhesive layer; 3, catenary cable; 4, construction coats direction; 5, seal; 6, isolation layer.
The specific embodiment
Example structure as shown in Figure 1; opening tubular type catenary insulation protective jacket is by insulating barrier 1; insulation adhesive layer 2; isolation layer 6 stack twist up drums; insulating barrier 1 inside face is connected with insulation adhesive layer 2; insulation adhesive layer 2 outside face are coated with isolation layer 6; their developed surface be rectangle structure as shown in Figure 2; isolation layer 6 width of cloth cover on tack coat 2; insulating barrier 1 is below insulation adhesive layer 2; insulating barrier 1 insulation adhesive layer 2; isolation layer 6 is pressed; in; on be superimposed; be wound into the helix tubular; insulation adhesive layer 2 grows part for sealing 5 than insulating barrier 1; it covers on the isolation layer 6; isolation layer 6 covers on the insulating barrier 1, and consistent with construction coating direction 4.
The developed surface of insulation protective jacket is a rectangle structure, and it is 500～1500cm that the developed surface of insulating barrier 1 is of a size of length, and wide is 20～35cm, and thickness is 0.15～0.35cm.Insulation adhesive layer 2 length grow 0.5～2cm than the length of insulating barrier 1; The width of insulation adhesive layer 2 grows 1～4cm than the width of insulating barrier 1; The thickness of insulation adhesive layer 2 is identical with the thickness of insulating barrier 1.Isolation layer 6 sizes generally equal insulation adhesive layer 2 length and width dimensions, also can appropriateness greater than the size of insulation adhesive layer 2, isolation layer 6 plays protection insulation adhesive layer 2.
Insulating barrier 1, insulation adhesive layer 2 are to be made by High molecular material.The High molecular material of insulating barrier 1 be natural rubber or EVA or haloflex or buna-S or polyvinylchloride or silaatic or EP rubbers or rubber and plastic sizing material or above-mentioned two or more and use blended rubber.The High molecular material of insulation adhesive layer 2 is poly-chloroprene rubber or viton or TPR, TPE or butadiene rubber or butyl rubber or modified polyvinyl chloride.Catenary cable 3 can be the free-throw line footpath of the used catenary of electrified railway.The color of insulating barrier 1 is main with blueness, and it includes red colour system, yellow system, black system, white color system, green system.
During use as shown in Figure 3:
(1), with the catenary cable 3 usefulness gasoline of required coating the surface contaminants Impurity removal, avoid impurity thing flashover, influence insulating power, protecting sleeve surface wiped clean.
(2), insulating barrier 1 and insulation adhesive layer 2, isolation layer 6 are superimposed, isolation layer 6 is last, tack coat 2 is in the centre, insulating barrier 1 is following, isolation layer 6, insulation adhesive layer 2 is superimposed up and down respectively with insulating barrier 1, removes the isolation layer 6 above the insulation adhesive layer 2, be the axle center with the catenary with insulating barrier 1 and insulation adhesive layer 2 in the shape of a spiral wire coat direction 4 along construction and closely be wound into tubular, firmly compress compacting between layer and the layer, make its tight bond.5 edge construction coating directions, 4 opposite senses that seal of insulation adhesive layer 2 outer are bonded on the insulating barrier 1, and firmly compress compacting, make its tight bond.
(3), because insulation adhesive layer 2 length grow 0.5～2.0cm than insulating barrier 1, at the two ends of opening tubular type catenary insulation protective jacket that insulation adhesive layer 2 is tight along stretching the part shutoff, prevent that aqueous vapor from corroding.
(4), tightr for making opening tubular type catenary insulation protective jacket bonding, the outside must apply external force, firmly twines with adhesive tape to get final product.
