Description
Technical field
The invention belongs to circuit registration device technical field, relate to a kind of applied to high-speed railway touching net push off mode elastic damper supporting mechanism.
Background technology
Contact net system is the transmission line of electricity of the special shape of powering to electric locomotive of downline overhead erection.It is made up of a few part in contact suspension, supportive device, registration device, pillar and basis.Contact suspension comprises contact wire, dropper, catenary and union piece.In China's development rapidly, up to now, total kilometrage numerical digit ranks first in the world high speed railway, therefore ensures that the normal operation of railway has very important economic implications and social value.
Applied to high-speed railway touching net system is a kind of typical wind sensitive structure, and what its wind-induced vibration directly affected motorcycle pantograph gets stream.But in recent years because of the contact system Frequent Accidents that windburn causes, scope, throughout all parts of the country, causes great railway transport economy to lose.Show the statistical analysis of all accidents of contact system, the fault that wind action causes has accounted for sizable ratio, becomes the principal element affecting safe train operation.Typical contact net system wind-induced damage accident has two large classes, the accident caused apart from not enough guiding discharge by wire insulation after large wind-induced windage yaw and windage yaw, and contact net system generation wind-induced vibration or the component damage waving and cause.
Beijing-Shanghai High-Speed Railway is since in July, 2011 opens, and that reports out is had 4 by large wind-induced contact system accident.On July 10th, 2011, Shandong there occurs the power-off of contact system fault within the border and causes 19 times Train delays because of strong wind, and this is the accident caused because skew occurs positive feeder; 12-14 day in July, 2011, G102 time, G114 time, G105 time train of high-speed motor train unit at eastern station, Beijing-Shanghai express railway Suzhou, there is pantograph and catenary fault in Changzhou, station, Tai'an, cause line contacts bad, make train speed sensor et out of order, cause reducing running velocity or even stoppage in transit; On March 23rd, 2012, strong wind " blows " again Beijing-Shanghai express railway disconnected, and Beijing reaches that part contact net between south, Tianjin has a power failure, southern station, Tianjin breakdown of equipment occurs and causes part Train delay in the south; On November 11st, 2012, Beijing-Shanghai express railway Tai'an to Qufu section comes in contact net fault again, and high wind makes the line feeder et out of order on pillar top.So, with regard to how improving contact system structural system, improve its structures under wind performance and become focal point instantly.
For the anti-wind research of contact system, in current engineering maintenance, have consider in wind gap district or bent slow location by reduce an intercolumniation span, to set up wind support or bracing wire, mode in the bracing wire of push off mode place device " V " type at just location place, reduce contact wire windage yaw.But due under high wind conditions, the change of steady arm displacement also can cause the windage yaw of contact wire to increase, and said method is very not remarkable for its windage yaw inhibition, no doubt these measures serve certain windbreak function, but fundamentally do not solve the fault caused because of wind loading.For high wind region, now adopt wind break wall, paravent, the on the ground mode in tunnel to carry out windproof process, but because its cost is higher, it is complicated to safeguard, also makes it apply and receive impact.
Damper is a kind of common energy-consuming shock absorber, is widely used in the industrial circles such as building, bridge, automobile, equipment at present.The wind-induced vibration response that elastic damper greatly can control contact wire is set in the termination of contact wire steady arm, dissipation contact wire kinetic energy effectively.
Application number be 200910051677.7 Chinese invention patent disclose a kind of elastic hanger damper for electrified railway contact line and manufacture method thereof, described damper comprises dropper twisted wire unit, damping generation unit and linkage unit, described dropper twisted wire unit is made up of steel strand, these steel strand can connect contact wire and catenary on the one hand, also be the attachment device of adopted damping generation unit on the other hand, described damping generation unit is made up of high-damping rubber body, its surface can embed each stock single line in dropper twisted wire unit with groove, be subject to tension force effect moment generation shock damping action, described linkage unit is steel component, comprise Horizontal messenger wire clamp and contact wire wire clamp, for dropper twisted wire and catenary and contact wire are coupled together.Existing ordinary elasticity dropper is mainly replaced to the dropper with damper by the technical scheme of above-mentioned patent disclosure, its dropper is made up of steel strand, these steel strand can connect contact wire and catenary on the one hand, also be the attachment device of adopted damper in addition on the one hand, but its manufacture craft is comparatively complicated, and prove in Practical Project that on dropper, institute is stressed less, therefore this device fails to play windbreak function well.
