Abstract

The utility model relates to an inserting type stayguy protection sleeve which comprises two semicircle or semioval plastic pipes, a positioning ring and a steel clip; the edge of the semicircle or semioval plastic pipe is extended with a round convexity and the other edge is a round concave surface; the two half pipes pass through the edge of the convex and concave surface to form a complete round or oval pipe; the positioning ring is provided with an opening groove and the inner hole is extended with a tooth; the outer edge is provided with a round ring; the top part of the protection sleeve is positioned on the steel wire which is fixed by the steel pin; the outside of the protection sleeve is provided with a white and red fluorescence mark paint or a red and white reflecting film. Therefore the utility model has alarming effect in day and night. To provide a protection sleeve to the stayguy is an efficient method to the man, livestock, car and the pole.

Description

Plug-in type backguy protective sleeve

The utility model belongs to power system power transmission and distribution technical field.

On power system power transmission and distribution overhead power line, some shaft tower is fixed with backguy, in case shaft tower is in running, and disequilibrium and toppling over.Because backguy does not have distinguishing mark, pedestrian livestock or vehicle easily mistake hit and have an accident.Existing backguy protective sleeve, the patent No. is 99225361.6, part comes with some shortcomings:

Zero existing backguy protective sleeve, its plastic pipe are only opened a seam in one side, during suit, must draw back this seam, just can be inserted in steel strand.Because seam is tight, adds the plastic pipe poor flexibility, the general staff, it is very difficult to draw back the slit.

Zero described backguy protective sleeve, a spacing collar is arranged at its top, slides up and down in order to place restrictions on plastic pipe, and prevents the friction of plastic pipe and steel strand and impaired.Because spacing collar only depends on friction spacing in plastic pipe, in use, not only for not the position, and itself be easy to from pipe, deviate from, make spacing collar ineffective.

Zero because backguy has various specification at the scene, and spacing collar also must have many specifications accordingly, and this has just increased the on-the-spot trouble of installing and using.

The purpose of this utility model is exactly a kind of novel plug-in type anticreep backguy protective sleeve that designs in order to solve above-mentioned shortcoming.

This plug-in type backguy protective sleeve comprises two and half garden shapes or half ellipse garden shape plastic pipe.These two plastic pipe joints have the tongue and the groove of a garden shape respectively, when pegging graft, just in time match up and down.

This plug-in type backguy protective sleeve in use, can be held steel strand with lower tube half, and upper tube half by tongue and groove, is inserted lower tube half at the another side of steel strand, and promptly rail mounted inserts into garden pipe or ellipse garden pipe, and steel strand are just entangled.Owing between tongue and groove certain interval is arranged, so install very convenient.Garden pipe or ellipse garden pipe adopt the PVC plastic production, outer wall scribbles red, white alternate fluorescent signal paint or paste reflective membrane.In order to prevent that the fluorescent lacquer from fading too early, outside signal paint, also scribbles the clear finish that one deck antiultraviolet width of cloth is penetrated.Even this signal paint at night, as long as light-illuminating is arranged, also has bright demonstration effect.Thereby, no matter by day, or night, protective sleeve all can play should warning function.In addition, in order to prevent protective sleeve slippage up and down,, block steel strand with the steel wire clamp near the top of protective sleeve.Because the plastic pipe that protective sleeve is used has certain insulating effect, under special circumstances, backguy is charged, because protective sleeve has been arranged, does not also cause pedestrian or livestock to get an electric shock.

In order to prevent that plastic pipe is in operation and steel strand collision friction, damage is provided with centring ring at the top of plastic pipe mutually.Described centring ring axially has an open slot, and there is flange the outer, and interior edge is an odontoid.In when construction, by open slot, steel strand are embedded the location, centre, then, make flange entangle garden shape or the material pipe port is moulded in ellipse garden toward pressing down, till compressing with the plastic pipe port.Centring ring is interior along plastic layer is thinner all around, and is odontoid, utilizes the elasticity of plastics itself, can hold the different steel strand of thickness.

Loosening in order to prevent that upper tube half and lower tube half are subjected to displacement after insertion, before two semicanals insert, in groove coated special adhesive.Equally, before entangling the mouth of pipe, centring ring, also is coated with this bonding adhesive at the mouth of pipe position of quilt cover.Because the powerful cementation of bonding adhesive, make between two semicanals and centring ring and the mouth of pipe to become as a whole, no longer become flexible displacement.

Advantage of the present utility model: insert at the scene and draw bonding, very convenient, mouth of pipe location is very stable, simple in structure, easy to make, and cost is low, and long service life is compared with original backguy protective sleeve, has tangible advantage.Simultaneously,, can make the steel strand of thickness different size, all can both be inserted in easily owing to adopt a kind of tooth-shape structure at centring ring center.Described backguy protective sleeve can not only be used on the power system power transmission and distribution overhead power line, and can be used on built on stilts communication line, in the cement electric pole backguy of program circuit.

Accompanying drawings

Accompanying drawing 1 is the structure chart of plug-in type backguy protective sleeve.1 is half garden plastic pipe among the figure, also can make half ellipse garden plastic pipe; 2 is half garden plastic pipe protruding cross sections of garden shape on one side, and protruding cross section 2 of this garden shape and half garden plastic pipe 1 are integral, and the diameter of its garden shape is greater than the wall thickness of half garden plastic pipe 1.3 is recessed cross sections of shape, another side garden of half garden plastic pipe 1, and recessed cross section 3 of this garden shape and half garden plastic pipe 1 are integral, and the interior garden slightly larger in diameter in its recessed cross section 3 of garden shape is in the external diameter in the protruding cross section of shape, garden.Two halves garden plastic pipe, the rabbet rail mounted by both sides insert into a complete garden pipe or ellipse garden pipe.There is special adhesive 4 in 3 in protruding cross section 2 and recessed cross section.

Accompanying drawing 2 is centring rings of plug-in type backguy protective sleeve.7 is open slots among the figure, one side open slot 7 axial has a protruding garden, and centring ring interior along 5 one-tenth profiles of tooth, there is flange 6 outer.During construction, centring ring embeds backguy from open slot 7, behind backguy center in place, is pressed in pipe end down again and gets final product.
