Abstract
The utility model discloses an overhead rigid contact net suspension system which comprises a suspension unit and a convergence bar positioning wire clamp, wherein the convergence bar positioning wire clamp is fixed on the suspension unit in a manner of being adjustable in horizontal direction, and at least one part of the convergence bar positioning wire clamp is matched and connected with the suspension unit by an elastic suspension pendant. Compared with the prior art, the overhead rigid contact net suspension system has the following benefits: realizing the matching and connection of the convergence bar positioning wire clamp and the suspension unit by the elastic suspension pendant, optimizing the matching relationship of a pantograph and a contact net when a vehicle runs at the speed of over 80km/h, reducing the natural frequency of the rigid contact net, maintaining the original sag of the rigid contact net, and simultaneously being added with the mutual followship between the pantograph and the contact net, and avoiding the resonance area, thus reducing the contact loss rate of the vehicle pantograph and the rigid contact net during running, and thoroughly eliminating the phenomenon of continuous arc discharge.
Description
Technical field
The utility model relates to a kind of contact system Suspension System, belongs to city railway power equipment supply technical field, refers in particular to a kind of overheat rigid contact network Suspension System.
Background technology
At present, in the construction and operation process of a lot of urban track traffics in the whole nation, all generally use overheat rigid contact network to be train power supply.Existing overheat rigid contact network Suspension System has generally comprised suspension unit and bus duct steady ear; The bus duct steady ear is connected with the suspension unit coupling through the rigidity suspender member; And the principle of design of span is between the bus duct steady ear: adopt 8 meters and above span for speed per hour at the circuit of 80km/h, adopt the span less than 8 meters for the circuit that surpasses 80km/h.This design; When running velocity is no more than 80km/h; Can obtain good result of use, but arcing phenomenon continuously generally takes place between bow net when running velocity when 80km/h is above, explain that present overheat rigid contact network is not good enough to the running velocity suitability more than the 80km/h; Significantly shorten the service life of vehicle pantograph and rigid contact net line; And hide unpredictable traffic safety problem, and still do not have the solution of system both at home and abroad, this problem presses for thorough solution.
The utility model content

To achieve these goals, the utility model is realized by following technical scheme:
A kind of overheat rigid contact network Suspension System; Include suspension unit and bus duct steady ear; The bus duct steady ear is fixed on the suspension unit with the mode with adjustment in the horizontal direction, and at least a portion is connected with the suspension unit coupling through resilient hanger spare in the said bus duct steady ear.
Further, said bus duct steady ear is connected with the suspension unit coupling with resilient hanger spare through the rigidity suspender member respectively, and rigidity suspender member and resilient hanger spare are with man-to-man corresponded manner separation.
Further, said bus duct steady ear matees with suspension unit through rigidity suspender member and resilient hanger spare respectively and is connected, and rigidity suspender member and resilient hanger spare are with a pair of two corresponded manner separation.
Further, the amount of elasticity of said resilient hanger spare is more than or equal to 1/2 sag that produces under the rigid contact net gravity free state.
Further, said rigidity suspender member and resilient hanger spare are set to electrical isolation respectively.
Further; Said suspension unit includes mounting seat, vertical pole, cross bar and bolt, and mounting seat is installed in tunnel top, and vertical pole vertically is installed on the mounting seat; Cross bar is installed on the vertical pole with the mode that has in the vertical direction adjustment, and bolt vertically is installed on the cross bar.
Further, to have a place at least be that electrical isolation connects to the connecting portion between the vertical pole of said suspension unit, cross bar and the bolt three.
The utility model compared with prior art, its beneficial effect is:
The utility model realizes that through resilient hanger spare the bus duct steady ear is connected with the coupling of suspension unit; Optimize the matching relationship of vehicle pantograph and contact system when surpassing the 80km/h running velocity, reduced the natural frequency of rigid contact net, kept the original sag of rigid contact net; Suitably increased simultaneously bow net tracing ability each other; Avoid resonance zone, reduce the vehicle pantograph when operation and the contact loss rate problem of rigid contact net, thoroughly eliminate the phenomenon of continuous arcing thereby reach.
