Description
Technical field
The utility model relates to a kind of the 3rd rail bracing frame that is applicable to electrified track traffic.
Background technology
Existing City Rail Transit System is electrical automation system, and voltage class has DC750V and DC1500V.Train obtains electric energy and is divided into pantograph basically and is subjected to electricity and third-rail current collection dual mode: pantograph electric means: be the charged cable of side suspension on the line, the roof of train is installed pantograph, pantograph slides in the contact of charged cable and obtains electric energy, and this is subjected to electricity the same substantially with traditional tramway train.The third-rail current collection mode: be in the rolling stock traveling steel rail outside the 3rd charged rail to be installed, the train corresponding position is installed pantagraph current collector, and pantagraph current collector slides with the contact of the 3rd rail and obtains electric energy.The third-rail current collection mode is because the cross section is big, and through-current capability is strong, and installation and maintenance all do not need advantage such as special engineering maintenance cart more and more to be widely adopted.
In the system of the electric automatization urban track traffic of adopting the third-rail current collection mode, ground substation is transferred to the 3rd rail with electric energy, train is subjected to stream that electric energy is passed to the train bus by the pantagraph current collector that is contained on the train bogie truck with dynamic contact of the high speed of the 3rd rail, for train provides traction and controls required electric energy; Simultaneously, when train carried out regenerative brake, the unnecessary electric energy that regenerative brake is produced fed back to ground power supply system by pantagraph current collector with dynamic contact of the 3rd rail again; So, it can be a key node that influences the train reliability service that high speed dynamic stability between pantagraph current collector and the 3rd rail is subjected to fluidity, and the ride comfort of the 3rd rail and the 3rd rail are subjected to stream interface and datum clamp face, the parallelism that is the rail upper surface is to influence the stable key factor that is flowed of train pantagraph current collector, that is to say that the setting accuracy of the 3rd rail is to influence the key factor that can the electric automatization urban track traffic stable operation.Simultaneously, behind the 3rd rail installation in position, the 3rd rail supporting construction can not be excessive to the Clamping force of the 3rd rail, can not hinder required freely the stretching of expanding with heat and contract with cold of the 3rd rail.The 3rd rail installation work amount is big, and the installation of the high-efficiency high-accuracy of the 3rd rail needs a kind of the 3rd suitable rail bracing frame.
Chinese patent " 201010295687.8 " the 3rd rail supporting component and insulating support thereof, it comprises the 3rd rail supporting component and rack body, and wherein rack body is made of body under support upper body and the support, and it forms height adjustment structure; The support upper body has mounted base, is used for installing full skirt and the 3rd rail supporting component.
The 3rd rail supporting construction of existing the 3rd rail supporting construction and above-mentioned patent disclosure, its weak point: they all do not provide slightly, structure is implemented in accurate adjustment step by step, do not have the beat adjustment structure yet, are difficult to take into account setting accuracy and efficient.Take a broad view of the subway line that existing domestic the 3rd all rail is powered, unit in charge of construction has usually reduced the setting accuracy of the 3rd rail for the saving cost, particularly the ride comfort of the 3rd rail does not have to guarantee substantially, only just with the 3rd rail pantagraph current collector face with respect to the vertical error control of rail rail level at ± 6mm.The contradiction that the raising of the subway running velocity that the 3rd rail is flowed and the 3rd rail construction precision are not high is increasing, hampers the 3rd rail and is subjected to the application of streaming system in urban track traffic.In the exchange of technology of carrying out with MTR, when mentioning the requiring of ride comfort of the 3rd rail, the related personnel of MTR shows signs of reluctance to quality assurance, it is little that subject matter is exactly that existing the 3rd rail supporting construction can be regulated degree of freedom, mounting process does not segment thick accurate adjustment, does not support the 3rd rail of high-efficiency high-accuracy to install.
