Abstract
The invention relates to a special tool for dual protection of a wire of a strain tower. The special tool comprises a U-shaped fixture connected with a cross arm, wherein a bolt used for locking the cross arm is installed on a flange on one side of the U-shaped fixture, an insulating rope is connected to a flange on the other side of the U-shaped fixture, and a U-shaped retaining ring is connected to the other end of the insulating rope. The U-shaped fixture is formed by finish machining high-quality special steel. The insulating rope is made of insulating nylon yarn. The head portion and the tail portion of the insulating rope respectively form a closed loop, and the two closed loops are connected with the U-shaped retaining ring and the U-shaped fixture respectively. The special tool aims to overcome the defects that when a wire clamping device is used for dual protection of an original wire, a closed loop is not formed and the wire falls off easily when the wire clamping device is in the loose state, and improve the safety of people, equipment and lines when line repair personnel conduct replacement of a strain insulator string and other operation on the power transmission line strain tower with a 35 kV voltage or a higher voltage.
Description
Technical field
The present invention relates to a kind of strain rod tower wire two pipe protection specific purpose tools.
Background technology
Line maintenance personnel change in the work such as strain insulator string on 35kV and above power line tension shaft tower, need to change original stress, by wire and other imposts by originally transferring on insulator string, gold utensil, strain clamp on take-up instrument (as double hook, wire grip etc.), so, the anti-loose safe important task of power line tension shaft tower wire is just born by take-up instrument entirely.Wire below often has some circuits of being crossed over, house, road, factory building etc., if take-up instrument exists potential safety hazard, will likely cause security incident.According to " electric power safety working regulation (circuit pack) " requirement, must change at transmission line and in the work such as insulator string, adopt the anti-loose safeguard measure of wire.The anti-loose safeguard measure of wire in the past adopting is to block wire in side of wire was lead clamping device, and this connected mode belongs to not closed loop and connects, and wire, under relaxed state, is easy to, because vibrations cause coming off, have potential safety hazard.Therefore; not closed loop must take measures to overcome former wire two pipe protections use lead clamping device time; under relaxed state, hold caducous problem; under the unfavorable conditions such as wire vibrations; still can guarantee that anti-loose two pipe protections of wire play a protective role, and applicable on all 35kV and above power line tension shaft tower.
Summary of the invention
The problem that the present invention is directed to above-mentioned prior art existence is made improvement; be that technical problem to be solved by this invention is to provide a kind of strain rod tower wire two pipe protection specific purpose tools; be not closed loop when making up and solve former wire two pipe protections uses lead clamping device; under relaxed state, hold caducous weak point, raising line maintenance personnel change the safety of the person, equipment and circuit in the work such as strain insulator string on 35kV and above power line tension shaft tower.
In order to solve the problems of the technologies described above; technical scheme of the present invention is: a kind of strain rod tower wire two pipe protection specific purpose tools; comprise a U-shaped jig being connected with cross-arm; on one side wing of described U-shaped jig, the bolt for locking cross-arm is installed; on its opposite side wing plate, be connected with insulating cord, the other end of described insulating cord is connected with U-shaped clasp.
Further, described U-shaped jig adopts the fine finishining of high-quality special steel to form.
Further, described insulating cord is made with insulating material nylon yarn, and its head, afterbody respectively form closed loop and be connected with U-shaped clasp, U-shaped jig respectively.
Further, described U-shaped clasp adopts the special steel matching with strain clamp nominal pulling force and coefficient of safety to be made.
Compared with prior art; the present invention has following beneficial effect: at side of wire was; the reconnaissance of two pipe protections is transferred on strain clamp from wire, and force way changes intermetallic ring into and encircles the pulling force interlocking from intermetallic frictional force, and the mode of connection never closure state changes closure state into.At cross-arm side, change the connection of jig standard into from simple canoe connection and be equipped with canoe, jig and cross-arm are fixed with bolt, jig and cross-arm contact area strengthen, interlock is better, and distribution of force is more reasonable and be not easy the phenomenons such as generation gets loose, displacement, operates more convenient.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the embodiment of the present invention.
Fig. 2 is embodiment of the present invention operating state vertical view.
Fig. 3 is embodiment of the present invention operating state end view.
In figure: 1-U shape jig, 11-bolt, 2-insulating cord, the U-shaped clasp of 3-, 4-cross-arm, the U-shaped ring of 5-, the U-shaped draw ring hole of 6-strain clamp, 7-strain clamp, 8-wire.
Embodiment
Embodiment mono-: as shown in Fig. 1 ~ 3; a kind of strain rod tower wire two pipe protection specific purpose tools; comprise a U-shaped jig 1 being connected with cross-arm 4; bolt 11 for locking cross-arm is installed on one side wing of described U-shaped jig 1; on its opposite side wing plate, be connected with insulating cord 2, the other end of described insulating cord 2 is connected with U-shaped clasp 3.
In the present embodiment, described U-shaped jig 1 adopts the fine finishining of high-quality special steel to form.
In the present embodiment, described insulating cord 2 use insulating material nylon yarns are made, and its head, afterbody respectively form closed loop and be connected with U-shaped clasp 3, U-shaped jig 1 respectively.
In the present embodiment, described U-shaped clasp 3 adopts the special steel matching with strain clamp nominal pulling force and coefficient of safety to be made.
When use, first U-shaped clasp 3 is connected with wire 8 by wire connecting ends, then U-shaped jig 1 is fixed on cross-arm 4, and lock stuck with bolt 11.Described wire connecting ends is by U-shaped ring 5, the U-shaped draw ring hole 6 of strain clamp, strain clamp 7 all linked with one another connecting to form successively.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
