Abstract
The utility model provides a pantograph air spring damping platform for an electric locomotive, belonging to the technical field of an electrified railway. The utility model aims to reduce the vibration of a pantograph by using the damping platform, so as to reduce the consumption of the pantograph and a contact wire, and improve the current collecting quality. According to the technical scheme to solve the problem, a damping platform is formed by a base plate of the damping platform, an air spring, an oil pressure damper and a limiter, and is mounted on a roof of the electric locomotive; and then the pantograph is mounted on the base plate of the damping platform. The inflation pressure of the air spring is regulated to achieve optimal damping effect. The pantograph air spring damping platform is mainly used for the pantograph of the electric locomotive.
Description
Technical field
The utility model belongs to the electrified railway technical field, particularly the stable technology of block of bow collector of electric locomotive.
Background technology
Existing block of bow collector of electric locomotive all is installed on the electric locomotive top board through insulator rigidly both at home and abroad; The vibration that the irregularity of circuit causes is directly passed on the pantograph; The lever amplification has also been passed through in some vibration, though pantograph has the pressure of 70N to contact wire, certain off-line is arranged also during high speed; This will accelerate the loss and reduction current carrying quality of contact wire and pantograph, and this is one of key factor of restriction raising road speed.Some country once tested through a portal frame pantograph was installed on the engine truck, but because of the reasons such as restriction in space, locomotive both sides, can't reach good effect.Though China Railway High-speed speed is very fast, maintenance cost is very high, comprising the service expenditure of pantograph and contact wire.Overseas high speed railway majority state government except that Japan gives and subsidy, and Japan is high speed railway operation country the earliest, but does not pursue too high speed, because of ground traffic tools from energy consumption and loss speed too fast be uneconomic.
The utility model content
The purpose of the utility model provides a kind of block of bow collector of electric locomotive spring damping platform, and it can reduce the vibration of pantograph effectively, thereby reduces the loss of pantograph contact wire and improve current carrying quality.
The purpose of the utility model is realized that by following technical scheme technical matters to be solved is with a vibration reduction platform vibration of electric locomotive roof to be isolated, and reduces the vibration of pantograph.Solve its technical matters employing and comprise vibration reduction platform substrate, spring, oil-pressure damper; The two ends of vibration reduction platform substrate upwards are bent to form broken line type; Four angles of platform substrate have a limiting device to be installed on the electric locomotive top board respectively; Four angle cross line directions of platform substrate are by entad setting gradually oil-pressure damper and air bellow outward respectively; Air bellow and oil-pressure damper are located between electric locomotive top board and the platform substrate, and pantograph is installed on the vibration reduction platform through four insulators, realize receiving the insulation between electricity and the platform substrate.For pantograph nuisance vibration be included in the displacement of the lines of Z-direction, around the X axle with around the angular transposition of Y axle, divide on the railway the above three kinds of displacements of another name for sink-float, sidewinder and nod.It is difficult making above three kinds of displacements all reach best effectiveness in vibration suppression; The benefit of selecting air bellow for use is can be according to the contact loss rate of pantograph; The inflation pressure of adjustment in air bellow makes it reach optimum efficiency, and keeping pantograph is the pressure of 70N all the time to contact wire.
Beneficial effect compared with prior art is the vibration that reduces pantograph.Thereby reduce the loss of pantograph contact wire and improve current carrying quality.The inflation pressure of adjustment in air bellow, keeping pantograph is the pressure of 70N to contact wire all the time, reaches than pantograph is directly installed on the better effect that flowed on the electric locomotive top board.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The contrast accompanying drawing is done and is further described below, and for describing the convenient rectangular axes 1 of setting, directions X is the locomotive working direction, and the Z direction is a vertical, the axis of coordinate of XOY for axially seeing down from Z.In order not take too many Z to height, vibration reduction platform substrate 2 two ends are bending upwards, and vibration reduction platform is symmetrical in the X axle, all only sees half the among Fig. 1.Vibration reduction platform is by the air bellow 3 that is installed in four jiaos of vibration reduction platform bending parts, and oil-pressure damper 4 is formed with limiting device 5.The two ends of vibration reduction platform substrate 2 upwards are bent to form broken line type; Four angles of platform substrate 2 have a limiting device 5 to be installed on the electric locomotive top board 6 respectively; Four angle cross line directions of platform substrate 2 are by entad setting gradually oil-pressure damper 4 and air bellow 3 outward respectively; Air bellow 3 and oil-pressure damper 4 are located between electric locomotive top board 6 and the platform substrate 2, and pantograph 7 is installed on the vibration reduction platform through four insulators 9, realize receiving the insulation between electricity and the platform substrate.Air bellow, oil-pressure damper all have approved product, and its lower end is fixed on the locomotive top board 6, and the upper end is fixed on the vibration reduction platform substrate 2.Limiting device 5 restriction pantographs do not exceed the action radius of permission; The thin bar in upper end passes hole bigger on the vibration reduction platform substrate 2; But diameter less than thick part; Thick part restriction vibration reduction platform 2 extreme displacements, for pantograph 7 for nuisance vibration be included in the displacement of the lines of Z-direction, around the X axle with around the angular transposition of Y axle, divide the above three kinds of displacements of another name for rising and falling, sidewinder and nodding on the railway.It is difficult making above three kinds of displacements all reach best effectiveness in vibration suppression; The benefit of selecting air bellow for use is can be according to the contact loss rate of pantograph; The inflation pressure of adjustment in air bellow makes it reach optimum efficiency, and keeping pantograph is the pressure of 70N all the time to contact wire 8.
