Abstract
The utility model discloses a composite insulator end-crimping structure, comprising a hardware fitting and a silicon rubber sleeve, wherein, an annular recess is provided on the internal wall at the end of the hardware fitting and toothed annular grooves are arranged at both ends of the annular recess; a coupling agent is applied on the internal wall at the end of the hardware fitting; a sealant is required to be applied on the surface of the silicon rubber sleeve being arranged to contact the internal wall at the end of the hardware fitting; the end of the hardware fitting is crisped on the silicon rubber sleeve being applied with the sealant and the silicon rubber sleeve is inserted in the annular recess and the annular grooves at the end of the hardware fitting. The utility model has a high mechanization and can minimize artificial influences and prove to be easy for control, effectively improve the sealing reliability, produce a simple structure and good sealing, reduce the cost and shorten the manufacturing cycle dramatically, improve the manufacturing efficiency, reducing the artificial workload and produce composite insulators with few maintaining demands.
Description
One, affiliated technical field:
The utility model belongs in a kind of ultra-high-tension power transmission line with composite insulator end crimping hermetically-sealed construction.
Two, background technology:
Compress hermetically-sealed construction with the composite insulator end in the existing ultra-high-tension power transmission line, be that our factory improved on the basis of traditional room temperature glue sealing in 1999, be on former sealing basis, to have increased a reasonable high temperature silicon rubber seal of elasticity, be enclosed within on the sheath, rubber seal is fitted in the sealing position by the end metal-coating again, it is whole that sealing ring and fluid sealant form a sealing, fluid sealant no longer exposes, prolonged its ageing time, metal-coating also plays the protective action to the sealing position.Along with large-scale production, the deficiency that reflects this structure gradually: complex structure, seal area has a plurality of interfaces to exist, the manufacturing cost height, and the production cycle is long, manual operations is many, labour intensity is big, the control point is many, easily produce cumulative errors, cause the sealing reliability of individual product poor, and in case have an accident, the labyrinth of sealing brings great difficulty to accident analysis again, and maintenance is complicated.
Three, summary of the invention:
The utility model is exactly to solve now with the problems referred to above that exist in the technology, provides a kind of simple in structure, the composite insulator end crimping hermetically-sealed construction that sealing property is better, sealing reliability is high.
For addressing the above problem, technical solution of the present utility model is: a kind of composite insulator end crimping hermetically-sealed construction, it comprises gold utensil, silicone rubber jacket, the end inwall of gold utensil has annular groove, the annular groove two ends also have the zigzag groove, gold utensil end inwall is smeared coupling agent, silicone rubber jacket and gold utensil end inwall contact-making surface are smeared fluid sealant, the end of gold utensil is crimped on the silicone rubber jacket of smearing fluid sealant, and the silicone rubber jacket end embeds in the annular groove and zigzag groove of gold utensil end inwall.
The utility model has one deck fluid sealant at the place of connecing that faces of silicone rubber jacket and gold utensil end and silicone rubber jacket overlay region.
The utility model directly is crimped on gold utensil on the silicone rubber jacket with equipment, has saved high temperature silicon rubber seal and end metal-coating, and is simple in structure, and the identical compression joint technique that the plastic deformation of gold utensil end adopts gold utensil and plug to connect is realized.The utility model is realized high-intensity sealing by the elastically-deformable interaction of plastic deformation of metal and silicon rubber, and at seal area, silicone rubber jacket is equivalent to the silicone rubber O-ring of super large.Because the compression of gold utensil end increases seal area sheath silicon rubber packing, thereby improve the air-tightness of seal area.The sawtooth ring-shaped groove of gold utensil end inwall design makes silicone rubber jacket contact with gold utensil axial section straight line and becomes the curve contact, increases contact area, effectively improves sealing effectiveness.The annular groove of gold utensil end inwall design, after the gold utensil crimping, silicon rubber is full of groove, plays the effect of O-ring seals, and further the enhanced leaktightness effect has reduced the generation at interface simultaneously.Seal area closes by the pressure bonding of coupling agent and special seal gum, the reinforced seal effect, and because the elimination in seal area silicone rubber jacket and gold utensil gap, special seal gum is stressed out, effectively eliminate the generation of bubble, and evenly be applied to by special tooling and facing of overlay region and silicone rubber jacket or gold utensil meet the place, form outermost sealant layer.In a word, the utlity model has production mechanization degree height, reduced the human factor influence, control has effectively improved sealing reliability easily, it is simple in structure, sealing property is better, can effectively reduce cost, shorten the product manufacturing schedule greatly, enhances productivity, reduce working strength of workers, make the maintenance of composite insulator simple relatively.
Four, description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model office profile.
Five, embodiment
As shown in Figure 1, present embodiment comprises gold utensil 1, silicone rubber jacket 5, the end inwall of gold utensil 1 has annular groove 4, annular groove 4 two ends also have zigzag groove 3, gold utensil 1 end inwall is smeared coupling agent, silicone rubber jacket 5 is smeared fluid sealant with gold utensil 1 end inwall contact-making surface, and the end crimping of gold utensil 1 also is bonded on the silicone rubber jacket 5 of smearing fluid sealant, and silicone rubber jacket 5 embeds in the annular groove 4 and zigzag groove 3 of gold utensil 1 end inwall.There is one deck fluid sealant 6 at the place of connecing that faces in silicone rubber jacket 5 and gold utensil 1 end and silicone rubber jacket 5 overlay regions.
