Description
Technical field
The utility model relates to a kind of contact system registration device of electrified railway.
Background technology
Contact system is the important component part of electrified railway, and train directly contacts with contact line conducting wire and obtains electric current, is locomotive supply electric power.The contact system registration device is the critical component of contact system, it is used to hang fixedly contact wire, directly contact with contact wire, when motorcycle pantograph passes through, registration device is parts immediate with it, existing registration device comprises steady arm body and positioning support, the abutment sleeve that steady arm body front end is connected is by the fixing contact system of steady ear, the perpendicular positioning ring that the location hook level of steady arm rear body riveted joint is inserted positioning support fixes steady arm, but along with China's high-speed electric railway implementation, requirement to the contact system steady arm is had higher requirement, its structure heaviness of existing registration device, the cross section is big, carrying structure is unbalanced, riveted joint is easily loosening, grip force is little, the tensile strength deficiency, steady arm weight is big, cause body sagging easily, make the contact system straightness accuracy that hangs between the adjacent registration device relatively poor, the motorcycle pantograph current carrying quality is affected, thereby influences train running speed, generally just reach speed per hour 120km/h, can't satisfy the 200Km/h high speed railway construction needs of high speed railway.And when express locomotive passes through, when pantograph is lifted contact system, also cause steady arm easily and contact to produce electric shock accidents.
The utility model content
The purpose of this utility model is: provide a kind of simple in structure, safe and reliable, hinged flexible, easy for installation, sufficient intensity, withstanding corrosion, non-maintaining, long service life, spacing registration device that cost is low arranged.
The purpose of this utility model realizes by implementing following technical proposals Come:
A kind of spacing registration device, comprise steady arm and positioning support, abutment sleeve, location hook that described steady arm comprises the steady arm body and is connected in the body front and back end is characterized in that: described positioning support bottom is fixed with the horizontal location ring, and there is a limited post at the middle part; The affixed location hook in described steady arm body rear end extends with the horizontal location ring of positioning support hinged downwards.
Described this body section of steady arm is a rectangle.
Described steady arm body terminal and and positioning support between windproof backguy is set.
Windproof backguy is set between the registration arm of the front end of described steady arm body and the positioning support that is connected.
Rivet between described steady arm body and location hook, the abutment sleeve.
Described steady arm bulk material adopts Aldrey, and location hook, positioning support adopt the Q235A forged steel, and abutment sleeve adopts Q235A forged steel or Aldrey AlMgSi1F31 material.
Described steady arm, positioning support and or the rivet surface preservative coat is arranged.
The preservative coat surface applied of described steady arm, rivet has conductive layer.
Adopt the utility model, by structure optimization to positioning support and steady arm, and the optimization of material, not only satisfy the Forging Technology requirement, improve connection reliability, improved the moment of holding with a firm grip, satisfied specified slippage requirement, the steady arm own wt alleviates the influence that bow net is produced and also decreases, and has improved the smoothness of contact wire.Coating preservative coat and conductive layer have increased the anti-corrosive properties and the electric conductivity that install.

The specific embodiment
As Fig. 1,2,3 are depicted as existing positioner device, comprise steady arm body 7 and positioning support 3, the abutment sleeve 8 that steady arm body front end is connected is by the fixing contact system of steady ear, the perpendicular positioning ring 5 that location hook 6 levels of steady arm rear body riveted joint are inserted positioning support fixes steady arm, but along with China's high-speed electric railway implementation, requirement to the contact system steady arm is had higher requirement, its structure heaviness of existing registration device, the cross section is big, and carrying structure is unbalanced, and riveted joint is easily loosening, grip force is little, the tensile strength deficiency, steady arm weight is big, causes steady arm sagging easily, make the contact system straightness accuracy that hangs between the adjacent registration device relatively poor, the motorcycle pantograph current carrying quality is affected, thereby influences train running speed, can't satisfy the high speed railway construction needs.
As shown in Figure 4, spacing registration device of the present utility model, the location hook of the two-sided riveted joint in steady arm rear end extends with the horizontal location ring of positioning support hinged to the bottom, the such draw bail of steady arm is more reliable, location hook is connected with positioning support flexibly, no catching phenomenon, and this body section of steady arm is a rectangle, and material is an Aldrey, weight reduction, when having overcome the steel bracket and having installed steel aluminium in conjunction with the time strength problem or steel aluminium wear problem when hinged.And improved the smoothness of contact wire, can improve locomotive running speed greatly.At the registration mast that the positioning support middle part is provided with, limited the amount of raising of steady arm, can avoid working as locomotive through out-of-date, during pantograph lifting steady arm, cause the steady arm body to contact and produce accident between pantograph with the registration arm of stationary positioned bearing.
The structure optimization of positioning support more adapts to the forging form, and the bolt of the fastening registration arm that is increased strengthens holding with a firm grip moment, satisfies specified slippage requirement.Because of positioning support is installed on the aluminium bowl arm configuration, and the friction coefficient of steel is littler than aluminium, and its material adopts the Q235A forged steel.Location hook, positioning support, abutment sleeve adopt the Q235A forged steel, and intensity and performance figure are higher than external aluminum alloy material.Be adapted to the big passenger-cargo mixed race high speed of the 160Km/h electrified railway of contact wire and catenary cross section and rated tension.Above abutment sleeve adopts import Aldrey AlMgSi1F31 material, is adapted to the little 200Km/h railway line for passenger traffic high-speed electric railway of contact wire and catenary cross section and rated tension.
Zinc-plated at positioning support, spacing location hook, abutment sleeve surface heat, rivet surface, steady arm surface anodic oxidation treatment, form one deck preservative coat on the registration device surface, by conduct electricity fat in steady arm body, location hook, abutment sleeve, rivet preservative coat surface coating, thereby form one deck conductive layer on the steady arm surface, improved anti-corrosive properties of the present utility model, coupling reliability and electric conductivity.
As shown in Figure 5, between the rear end of steady arm body and the positioning support and between the registration arm of the front end of steady arm body and the positioning support that is connected windproof backguy 10 is being set, can adapting to open-air harsh environment, guaranteeing the reliability that connects.
As shown in Figure 6, between the rear end of steady arm body and positioning support, windproof backguy is set, removes and guarantee to connect more reliable, can also satisfy the adjustable requirement of limiting device.
