Abstract

The invention discloses a jumper splicing sleeve of an overhead power transmission line. The problems that the high-altitude operation is very difficult and the connection of the connected jumper is not reliable are solved in the prior art. The jumper splicing sleeve comprises an olivary internal splicing sleeve (1), wherein two external splicing sleeve caps (2) with the same structure are respectively sleeved on the internal splicing sleeve (1) from the left end and the right end of the internal splicing sleeve (1); the middle section of the internal splicing sleeve (1) is a section (6) with equal diameter; the left part section and the right part section of the internal splicing sleeve (1) are symmetrically arranged tapered pipe sections (4); the left part section and the right part section of the internal splicing sleeve (1) are respectively provided with a tightening seam (5); a convex locating and anti-loosing annular step (7) is arranged at a central part outside the pipe of the equal-diameter section (6) of the internal splicing sleeve (1); and the external splicing sleeve cap (2) consists of a tapered pipe cap body (10) and an annular cap bottoms (12). The jumper splicing sleeve of the overhead power transmission line is simple in structure and safe and convenient to mount in the field.

Description

Built on stilts electric power transmission line wire jumper splicing sleeve
Technical field
The broken string that the present invention relates to a kind of high-pressure delivery electric line connects frock, the wire jumper splicing sleeve that particularly a kind of two ends of the two high pressure pipelines that will break off links together.
Background technology
At present, the frock that continues of making somebody a mere figurehead the electric power transmission line wire jumper is mainly contained two kinds, a kind of is the bolt parallel groove clamp, and another kind is the hydraulic pressure splicing sleeve.Use the bolt parallel groove clamp to exist contact-making surface little, contact resistance is big, connects insecure problem.When using the hydraulic pressure splicing sleeve, because hydraulic test is heavy, exist hydraulic operation work high above the ground difficulty big, the operating time is long, can not adapt to the defective that power system operating mode changes.
Summary of the invention
The invention provides a kind of built on stilts electric power transmission line wire jumper splicing sleeve, solved big and the connected wire jumper contact resistance of high-altitude application task difficulty that existing apparatus exists big be connected insecure technical problem.
The present invention overcomes the above problems through following scheme:
A kind of built on stilts electric power transmission line wire jumper splicing sleeve; Comprise olivary interior splicing sleeve; In interior splicing sleeve, be provided with the wire jumper of built on stilts electric power transmission line; Two pipe caps that continue outward that structure is identical are socketed on the interior splicing sleeve from the right ends of interior splicing sleeve respectively, and the interlude of interior splicing sleeve is the equal diameter pipeline section, and the left part section of interior splicing sleeve and right part section are symmetrically arranged taper pipeline section; On the left part section of interior splicing sleeve and right part section, be provided with and tighten up seam; The center is provided with protruding positioning and locking annular steps outside the pipe of the equal diameter pipeline section of interior splicing sleeve, and the pipe outer wall of the equal diameter pipeline section in the left side of positioning and locking annular steps is provided with left external screw thread, and the pipe outer wall of the equal diameter pipeline section on the right side of positioning and locking annular steps is provided with right external screw thread; The pipe cap that continues is outward formed at the bottom of by taper pipe cap body and annular cap, at the bottom of the annular cap, is provided with internal thread, and the end eaves arranged outside at the bottom of the annular cap has the sealing locknut annulus.
The tapering of the tapering of taper pipeline section and taper pipe cap body is 3 degree, on the left part section of interior splicing sleeve and right part section, be provided with respectively to tighten up seam be three, these three are tightened up seam is that the radians such as axis direction of the interior splicing sleeve in edge are provided with at interval.
The present invention is simple in structure, on-the-spot installs that promptly safety is convenient again, can realize that wire jumper to different cross section carries out high-qualityly reliably continuing, and reusable.

Embodiment
A kind of built on stilts electric power transmission line wire jumper splicing sleeve; Comprise olivary in splicing sleeve 1, the double bounce line end of wire jumper 3 respectively from the right ends cross-under of interior splicing sleeve 1 to interior splicing sleeve 1, and be engaged togather in the middle position activity of interior splicing sleeve 1; Two pipe caps 2 that continue outward that structure is identical are socketed on the interior splicing sleeve 1 from the right ends of interior splicing sleeve 1 respectively; The interlude of interior splicing sleeve 1 is an equal diameter pipeline section 6, and the left part section of interior splicing sleeve 1 and right part section are symmetrically arranged taper pipeline section 4, on the left part section of interior splicing sleeve 1 and right part section, is provided with to tighten up seam 5; When interior splicing sleeve 1 pressurized; Tighten up seam 5 and tighten up, the caliber of splicing sleeve 1 attenuates in making, thereby compresses the wire jumper that quilt wherein continues; The center is provided with protruding positioning and locking annular steps 7 outside the pipe of the equal diameter pipeline section 6 of interior splicing sleeve 1; The pipe outer wall of the equal diameter pipeline section 6 in the left side of positioning and locking annular steps 7 is provided with left external screw thread 8, and the pipe outer wall of the equal diameter pipeline section 6 on the right side of positioning and locking annular steps 7 is provided with right external screw thread 9; Pipe cap 2 continue outward by 12 forming at the bottom of taper pipe cap body 10 and the annular cap, be provided with internal thread 11 in 12 at the bottom of the annular cap, 12 end eaves arranged outside has sealing locknut annulus 13 at the bottom of the annular cap; The internal threads 11 that are provided with in 12 at the bottom of the annular cap of the outer pipe cap 2 that continues on the left side of being inserted in from interior splicing sleeve 1 left side are spirally connected with the left external screw thread 8 that pipe outer wall at the equal diameter pipeline section 6 in the left side of positioning and locking annular steps 7 is provided with; Along with the pipe cap 2 that continues outward to right rotation with interior splicing sleeve 1 in the left side wire jumper firmly compress; Be engaged togather up to the sealing locknut annulus 13 of 12 end eaves arranged outside at the bottom of the annular cap and positioning and locking annular steps 7 in the convexity of the pipe outer center setting of the equal diameter pipeline section 6 of interior splicing sleeve 1; Sealing locknut annulus 13 and cooperating of positioning and locking annular steps 7 are to adopt interference fit, make continuing more closely and having locking function of wire jumper.
The tapering of the left part section of interior splicing sleeve 1 and the taper pipeline section 4 of right part section is 3 degree; About the tapering of taper pipe cap body 10 of the two outer pipe caps 2 that continue also be 3 degree; On the left part section of interior splicing sleeve 1 and right part section, be provided with respectively to tighten up seam 5 be three, these three are tightened up seam is that radians such as axis direction along interior splicing sleeve 1 are provided with at interval.
It is unreliable to the invention solves the parallel groove clamp connection; Accident potential such as easy heating and scaling loss; Solved also simultaneously that hydraulic tube continues that the work high above the ground difficulty is big, work strong high, the operating time is long; Shortcoming and problem such as can only disposablely use, for the continuing of wire jumper of ultra-high-tension power transmission line provides the simple and reliable frock that continues easily.
