Description

A kind of route cross-arm

Technical field

The utility model relates to insulator arrangement technical fields of transmitting electricity, more specifically, it relates to a kind of route cross-arm.

Background technique

In field of electrical equipment, cross-arm used for transmission line is the important matched structural of power transmission rod, for support conducting wire, Lightning conducter etc., and be allowed to keep certain safe distance by regulation.

Existing cross-arm generally uses compound cross-arm, and compound cross-arm usually by insulation mandrel and is set in outside insulation mandrel Protective case composition.In fixed insulator, generally fixed by the cooperation of bolt and nut, and screw rod break-through insulation mandrel and protection Set.Since insulation mandrel intensity is higher, such fixed form enables insulator preferably to be fixed.But due to screw rod It across insulation mandrel and protective case, can enter other substances such as air, rainwater inside protective case, so that insulating core can be accelerated The degree of aging of stick, shortens service life.

Utility model content

In view of the deficienciess of the prior art, passing through fixation the purpose of this utility model is to provide a kind of route cross-arm Insulation mandrel is isolated from the outside by set outer wall, insulation sleeve inner wall, baffle, so as to avoid the erosion of other substances such as air, rainwater Insulation mandrel greatly reduces the degree of aging of insulation mandrel, extends the service life of insulation mandrel.

To achieve the above object, the utility model provides following technical solution:

A kind of route cross-arm, including insulation mandrel and the protective case being set in outside the insulation mandrel, the insulation mandrel Vertical through holes are offered, the protective case includes being set in the insulation sleeve, peace that the insulation mandrel is outer and side is with an opening Mounted in the insulation sleeve open end and covering opening baffle, be connected to the insulation sleeve side wall and may pass through described vertical logical The fixing sleeve outside the baffle is simultaneously stretched out in hole, the fixing sleeve both ends with outside be connected to, the fixing sleeve inner wall be provided with and The internal screw thread of screw flight cooperation, the fixing sleeve and the baffle are interference fitted.

By using above-mentioned technical proposal, fixing sleeve outer wall, insulation sleeve inner wall, baffle inner wall is made to form the space of sealing, To which insulation mandrel to be isolated from the outside completely, and the screw rod of insulator can be threadedly engaged on the inner wall for being mounted on fixing sleeve, real The fixation of existing insulator.Insulation mandrel is isolated from the outside by fixing sleeve outer wall, insulation sleeve inner wall, baffle, so as to avoid Other substances such as air, rainwater corrode insulation mandrel, greatly reduce the degree of aging of insulation mandrel, extend insulation mandrel Service life.

Preferably, the vertical through holes inner wall of the insulation mandrel offers vertical card slot, and the fixing sleeve is provided with and institute State vertical card slot clamping engagement strip.

By using above-mentioned technical proposal, since when screw rod and fixing sleeve relatively rotate, the two can generate opposite effect Power, fixing sleeve has the trend rotated synchronously with screw rod, when the power used is larger, may destroy fixing sleeve and insulation sleeve connects It connects, is broken fixing sleeve with the junction of insulation sleeve, fixing sleeve is caused to be destroyed with insulation sleeve.Pass through setting for vertical card slot It sets, makes between fixing sleeve and insulation mandrel that there are relative restraints, when rotating screw rod, insulation mandrel can play support to fixing sleeve Effect, so that the junction of fixing sleeve and insulation sleeve be avoided to be destroyed.

Preferably, the inner wall of the fixing sleeve offers rhone.

By using above-mentioned technical proposal, when encountering rainy day, can be full of at fixing sleeve and screw flight cooperation Water can then improve the probability of screw rod corrosion for a long time；If the junction of the two is full of dust simultaneously, will lead to the later period can not be twisted It opens, influences to dismantle.By the setting of rhone, the probability of screw rod corrosion at rainwater and dust row, will can be on the one hand reduced, it is another Aspect can avoid blocking, facilitate the disassembly in later period.

Preferably, the baffle and the insulation sleeve grafting, which are glued, cooperates, and the splice ends of the two are in 45 °.

By using above-mentioned technical proposal, cooperation is glued in baffle and insulation sleeve grafting, makes to install more convenient；And by the two Splice ends setting it is at 45 °, the stitching portion that both can make not will receive the direct irradiation of the direct contact and sunlight of rainwater, thus The ageing time of glue can be slowed down, to prolong the service life.

Preferably, the connecting pin of the baffle and the insulation sleeve is provided with vertical convex block, the open end of the insulation sleeve Offer the vertical groove mating with the vertical convex block.

By using above-mentioned technical proposal, when installation, it first is coated with glue in vertical groove, then vertical convex block is aligned vertical Then vertical convex block is inserted into vertical groove by groove, make 45 ° of connecting pin splits of the two, completes to fix.

Preferably, the outer wall indent that the fixing sleeve passes through described baffle one end is provided with threaded area, the threaded area spiral shell Line is combined with fixed ring, and the fixed ring and the baffle push against.

By using above-mentioned technical proposal, although fixing sleeve and baffle are interference fitted, due to insulator can often by To the influence of wind-force, so that fixing sleeve and bolt that insulator will drive shake in all directions, to can make fixing sleeve and gear Occur gap between plate, and gap may be increasing over time, and then influences airtightness.By fixed ring with Threaded area is threadedly engaged, and the relatively fixed degree of fixing sleeve and baffle is substantially increased, to improve the stabilization of fixing sleeve Property, and then can substantially reduce and gap probability occur.

Preferably, the threaded area interference of the fixing sleeve is arranged with dubbin felt collar, and the fixed ring and the baffle press from both sides The tight dubbin felt collar.

It is rigid contact between fixed ring and baffle by using above-mentioned technical proposal, there can be certain interval.By anti- The setting of water malthoid circle improves the connection sealing between baffle and fixed ring, thus reduce air enter it is general in insulation sleeve Rate.

Preferably, the section of the insulation mandrel is rectangle, and having a size of 36 × 46mm.

Compared with prior art, the utility model has the advantages that:

1, insulation mandrel is isolated from the outside by fixing sleeve outer wall, insulation sleeve inner wall, baffle, so as to avoid air, Other substances such as rainwater corrode insulation mandrel, greatly reduce the degree of aging of insulation mandrel, extend the use of insulation mandrel Service life；

2, by the setting of rhone, the probability of screw rod corrosion, another party can on the one hand be reduced by rainwater and dust row Face can avoid blocking, facilitate the disassembly in later period；

3, it is threadedly engaged by fixed ring and threaded area, substantially increases the relatively fixed degree of fixing sleeve and baffle, from And the stability of fixing sleeve is improved, and then can substantially reduce and gap probability occur.
