Description
Technical field
The utility model overheat rigid contact network bus duct steady ear relates to a kind ofly in the track traffic rigid contact net, special-purpose with the built on stilts bus duct of support, makes the wire clamp of its location.
Background technology
Bus duct steady ear of the prior art, general employing is assembled into the design of integral type by two wire clamps.Chinese patent number is 01240444.6 to disclose a kind of bus duct steady ear.Like Fig. 1, shown in Figure 2; This bus duct steady ear is made up of two wire clip bodies 11, insulating gasket 12, dowel bolt 13, elastic cylindrical pin 14 and tie bolt 15; The horizontal direction symmetry is shaped on screw 16 on two wire clip bodies 11; The vertical direction symmetry is shaped on semicircle orifice 17, and tie bolt 15 passes screw 16 two wire clip bodies 11 are fixed together, and insulating gasket 12 is embedded on two wire clip bodies 11 through elastic cylindrical pin 14; Dowel bolt 13 passes semicircle orifice 17 and is sleeved on two wire clip bodies 11; The place, two ends that is positioned at tie bolt 15 on two wire clip bodies 11 is shaped on the anti-turntable 18 of nut, and the middle part of dowel bolt 13 is shaped on setscrew nut 19, and setscrew nut 19 is an integral structure with dowel bolt 13.When reality is used, after this two-piece type wire clip body need close up assembling with bus duct, utilize tie bolt 15 to be inserted in the anti-turntable 18 of nut, total is fixed.
Technique scheme, wire clamp and supporting insulator fixing, and the installation of wire clamp and bus duct, operational procedure inconvenience separately carries out simultaneously separately or arrangement in advance respectively, operating efficiency are low, during construction cost, take a lot of work.Connecting clamp is connected insecure with the dowel bolt of supporting insulator, when dowel bolt was connected with other parts, nut and dowel bolt rotated simultaneously, is not easy to site operation and installs.In horizontal loading effect drop wire clip meeting thereby canting is askew sticks up, bus duct can not accurately be located, and is prone to jam in the wire clamp content, increases the curved disconnected risk of supporting insulator.
The utility model content
In view of this, the technical matters that the utility model solved is promptly providing a kind of unitary construction, can make bus duct more accurately locate, can not jam in wire clamp, and move more failure-free bus duct steady ear.
The technical scheme of the utility model is: a kind of overheat rigid contact network bus duct steady ear,, comprise:
Main body rack is single integrated support structure, and the top is provided with axostylus axostyle, and the both sides, bottom are provided with screw rod;
Slide block is sheathed on the screw rod of main body rack both sides, and is fixed on the main body rack through nut.
Wherein, this screw rod and main body rack are made into integration.
Wherein, this axostylus axostyle and main body rack are made into integration.
Wherein, be provided with pressing plate and locking pad between this slide block and the nut.
Wherein, this main body rack is arc.
Wherein, the downward right-angled bend of this main body rack both-side ends is guaranteed accurately to locate between slide block and the bus duct.
Wherein this slide block has electric conductivity.
The beneficial effect of the utility model is: according to the said structure characteristic, the main body wire clamp is by the metal single integrated support structure of section bar, and structure is firm.
And screw rod and main body rack are designed to mutual indivisible entity structure, and preventing when tightening up nut, screw rod can be with not the tightening and rotate of nut, and the dismounting of necessary slide block and refitting operation are provided convenience when being installed on steady ear for bus duct.
And axostylus axostyle and main body rack are designed to mutual indivisible entity, and after this bus duct steady ear was loaded onto bus duct, wire clamp was locked immediately with captiveing joint of insulator and can not come off from insulator.
According to the said structure characteristic, this bus duct steady ear under the level load effect, wire clamp not can thereby canting, so bus duct accurate positioning property is unaffected.
According to the said structure characteristic, the bus duct of this bus duct steady ear can the jam wire clamp in, avoided the increase of supporting insulator bend loading.
According to the said structure characteristic, conductive slider is that bus duct and the necessary electric property of wire clamp charging operation and the required safety of maintenance effective grounding that has a power failure provide assurance.

The specific embodiment
As shown in Figure 3; Its structure for the utility model overheat rigid contact network bus duct steady ear is a scheme drawing; It comprises main body rack 1, slide block 2, pressing plate 3, locking pad 4 and nut 5, and main body rack 1 is that the top is provided with axostylus axostyle 7 by the metal single integrated support structure of section bar; The both sides, bottom are provided with screw rod 6, and axostylus axostyle and screw rod are made into integration with main body rack respectively.This main body rack 1 is fixed on the supporting insulator 9 of contact system through axostylus axostyle 7.This main body rack 1 is arc, guarantees wire clamp and the required space of bus duct, and have certain diastole property that the downward right-angled bend of both-side ends is guaranteed accurately to locate between slide block and the bus duct.
Slide block 2 is sheathed on the screw rod 6 of main body rack both sides; Slide block 2 has electric conductivity; And be fixed on the main body rack through nut 5, slide block 2 is disposed with pressing plate 3 and locking pad 4 with nut 5, and this structure can prevent effectively that the bus duct steady ear is under the level load effect; Wire clamp can canting, so bus duct accurate positioning property is unaffected.Main body rack 2 two bottom sides are located bus duct 8 by screw rod 6 fixing slide block 2 supports; This screw rod 6 is designed to an indivisible entity with main body rack 1; To prevent that when tightening up nut screw rod 6 can tightening and rotate the slip that this two slide block 2 allows bus ducts to produce because of the effect of expanding with heat and contract with cold therein with nut 5.
As shown in Figure 4, it is the rigid suspended bus duct steady ear of the utility model applicable cases scheme drawing in the subway tunnel rigid suspension catenary.The main body rack 1 of steady ear supports with the insulation that fixed pedestal insulator 9 and supporting traverse channel-section steel 10 are formed one group of vertical hanging, becomes a main composition part of city rail traffic overheat rigid vertical hanging contact system electric power system.The bus duct 8 of this bus duct steady ear can the jam wire clamp in, avoided the increase of supporting insulator 9 bend loadings.
To sum up, main body rack is become by the section bar metal work, and the axostylus axostyle that is provided with through the top is fixed on the contact system supporting insulator.These main body rack both sides are provided with screw rod, through pressing plate, locking pad and nut slide block are fixed on the main body rack below.Slide block is as the platform of direct support of bus duct and slip.The wire clamp main body rack adopts the section bar metal to process single formula structure; It is winning that assembly formula structure is closed in the split of whole mechanics performance ratio prior art; In selection and design, optimized and the cooperating of bus duct; Guarantee bus duct safer use on wire clamp, reliable localization and slip flexibly, the environmental protection of wire clamp production technology, cost and construction technique are further optimized.
In sum, the utility model provides a kind of later-model rigid suspended bus duct elasticity steady ear, is the application of in accordance with the law offering novel patent; The technology contents of the utility model and technical characterstic the sixth of the twelve Earthly Branches disclose as above, yet the personage who is familiar with this technology still possibly utilize the announcement of the utility model, and do various, essence and mentally also the end can disclose different replacement and modification with the utility model.Therefore, the protection domain of the utility model should be not limited to embodiment announcement person, and should comprise various replacement and the modifications that are not different from the utility model in fact, and is contained by following claim.
