The elastic busbar hard-soft transition apparatus comprises a busbar body, a plate spring element sets, a U-shaped connection plate set, a cable clamp set, an electric connection wire and an electric connection copper bar. With the special structure having the plate spring elements and the electric connection wires, stable transition of pantograph between soft-hard contact overhead line system modes, safety and reliability is provided and faults such as pantograph hitting and drilling can be avoided; elevation of the pantograph is gradually decreased from flexibility to rigidity and hard points are avoided; from rigidity to flexibility, shakes of pantograph due to stress mutation can be avoided and wear of the pantograph can be reduced; and the elastic busbar hard-soft transition apparatus can be installed on a straight line section and also a curve section.
Description
Technical field
What the present invention relates to is a kind of elasticity bus duct rigid-flexibility transition device, belongs to the technical field of urban track traffic rigidity supply network.
Background technology
The overhead contact line of electrified railway and urban track traffic generally adopts rigid suspended more in tunnel, adopts flexible suspension on the ground or on overpass.Rigid-flexibility transition refers to the linking transition between rigid suspended and flexible suspension two kinds of contact system patterns.And in rigid-flexibility transition scheme, bus duct rigid-flexibility transition device is one of vital part.A kind of bus duct rigid-flexibility transition device disclosed in patent No. CN200620078307, disclosed in it, a kind of version of notch-cut type bus duct rigid-flexibility transition element that adopts is every one section of grooving at the flexible contact line entrance point of rigidity bus duct, depth of rebate reduces successively, realizes rigid-flexibility transition to reach the change of rigidity echelon.But the stiffness variation between two grooves is discrete, therefore still there is hard spot at two groove intersections, just hard spot weakened and resolve into several hard spots.Further, in the course of processing, this kind of device needs repeatedly to excise material on bus duct to form multiple groove by Linear cut, and processing is inconvenient, productive costs is higher.
A kind of Rigidity-flexibilitytransition transition busbar and for example disclosed in patent No. CN201310536017, pantograph is reduced in the impact being subject to contact stiffness change by amplitude during rigid-flexibility transition portion by adopting continuous print intermediate incline, thus due to the hard spot that rigidity step variation brings in elimination Rigidity-flexibilitytransition transition busbar, reduce the vibration of electric car pantograph when transitional region.But this device is generally only applicable to linear section, at segment of curve owing to there is circuit superelevation, notch-cut type rigid-flexibility transition produces and reverses, and the place more weak in its end rigidity exists by the danger twisted off.In addition, existing bus duct adopts aluminum alloy materials to be made, its elasticity and to bear twisting resistance more weak, and endurance is poor easily to rupture.
