Abstract

The utility model discloses a jumper splicing sleeve of an overhead electric power transmission line. The jumper splicing sleeve resolves problems of high task difficulty in aloft operation and unreliable jumper connection of a conventional device. The jumper splicing sleeve comprises an olivary inner splicing sleeve (1). Two outer splicing sleeve caps (2) with same structure are sleeved on the inner splicing sleeve (1) from the left and the right ends of the inner splicing sleeve (1), respectively. An equal-diameter sleeve segment (6) is arranged in the center of the inner splicing sleeve (1). The left part segment and the right part segment of the inner splicing sleeve (1) are conical sleeve segments (4) which are symmetrically arranged and are both equipped with frapping cracks (5). A protruding positioning anti-loosening circular ring step (7) is arranged at the middle part outside the equal-diameter sleeve segment (6) of the inner splicing sleeve (1). Each outer splicing sleeve cap (2) is composed of a conical sleeve cap body (1) and an annular cap bottom (12). The jumper splicing sleeve with simple structure is safe and easy to install on site.

Description

Built on stilts electric power transmission line jumper wire continuing pipe
Technical field
The present invention relates to a kind of connection of broken lines frock of high-pressure delivery electric line, particularly the jumper wire continuing pipe that links together of a kind of two ends of the two high-pressure delivery lines that will disconnect.
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 large, connects insecure problem.When using the hydraulic pressure splicing sleeve, because hydraulic test is heavy, exist hydraulic operation work high above the ground difficulty large, longevity of service 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 jumper wire continuing pipe, solved the large and wire jumper contact resistance that is connected of high-altitude application task difficulty that existing apparatus exists large be connected insecure technical problem.
The present invention is by the above problem of following solution:
A kind of built on stilts electric power transmission line jumper wire continuing pipe, 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 two ends, the left and right sides of interior splicing sleeve respectively, the interlude of interior splicing sleeve is the equal diameter pipeline section, the left part section of interior splicing sleeve and right part section are symmetrically arranged taper pipeline section, be provided with in the left part section of interior splicing sleeve and right part section and tighten up seam, the center is provided with the positioning and locking annular steps of projection outside the pipe of the equal diameter pipeline section of interior splicing sleeve, pipe outer wall at the equal diameter pipeline section in the left side of positioning and locking annular steps is provided with left outside screw thread, is provided with right outside screw thread at the pipe outer wall of the equal diameter pipeline section on the right side of positioning and locking annular steps; The pipe cap that continues outward forms at the bottom of by taper pipe cap body and annular cap, is provided with internal thread at the bottom of the annular cap, 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, arrange respectively to tighten up seam be three, these three are tightened up seam is that radian intervals such as axis direction along interior splicing sleeve arrange.
The present invention is simple in structure, on-the-spot installs that namely 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 jumper wire continuing pipe, comprise olivary interior splicing sleeve 1, the double bounce line end of wire jumper 3 respectively from two ends, the left and right sides 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 two ends, the left and right sides of interior splicing sleeve 1 respectively, the interlude of interior splicing sleeve 1 is equal diameter pipeline section 6, the left part section of interior splicing sleeve 1 and right part section are symmetrically arranged taper pipeline section 4, be provided with in the left part section of interior splicing sleeve 1 and right part section and tighten up seam 5, when interior splicing sleeve 1 pressurized, tightening up seam 5 tightens up, the caliber of interior splicing sleeve 1 is attenuated, thereby compress the wire jumper that quilt wherein continues; The center is provided with the positioning and locking annular steps 7 of projection outside the pipe of the equal diameter pipeline section 6 of interior splicing sleeve 1, pipe outer wall at the equal diameter pipeline section 6 in the left side of positioning and locking annular steps 7 is provided with left outside screw thread 8, is provided with right outside screw thread 9 at the pipe outer wall of the equal diameter pipeline section 6 on the right side of positioning and locking annular steps 7; The pipe cap 2 that continues outward 12 forms at the bottom of by taper pipe cap body 10 and annular cap, is being provided with internal thread 11 in 12 at the bottom of the annular cap, and 12 end eaves arranged outside has sealing locknut annulus 13 at the bottom of the annular cap; The internal thread 11 of 12 interior settings 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 is spirally connected with the left outside 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 arranges, along with firmly compressing to the wire jumper of right rotation with left side in the interior splicing sleeve 1 of the pipe cap 2 that continues outward, until the sealing locknut annulus 13 of 12 end eaves arranged outside is engaged togather with positioning and locking annular steps 7 in the projection of the pipe outer center setting of the equal diameter pipeline section 6 of interior splicing sleeve 1 at the bottom of the annular cap, 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, arrange respectively to tighten up seam 5 be three, these three are tightened up seam is that radian intervals such as axis direction along interior splicing sleeve 1 arrange.
It is unreliable to the invention solves the parallel groove clamp connection, the 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 large, work strong high, the operating time is long, shortcoming and the 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.
