Description
Technical field
The invention 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 the insulator rigidity both at home and abroad, and the vibration that the irregularity of circuit causes is directly passed on the pantograph, and the lever amplification has also been passed through in some vibration.Though pantograph has the pressure of 70N to contact wire, and certain off-line is also arranged during high speed, this will accelerate the loss of contact wire and pantograph and reduce current carrying quality, and this is one of restriction key factor of improving 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, and the high speed railway of Beijing to Tianjin is 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.
If use spring, oil-pressure damper constitutes vibration reduction platform and is installed on the locomotive top board, again pantograph is installed on the vibration reduction platform, but will to make the vibration reduction platform all directions that the favorable damping effect is all arranged be work less than.And the gyrocompassing platform just can be accomplished this point.The directionality of the gyro of high speed rotating is extraordinary, does not need too big gyro just can make its orientation for the so not too big object of pantograph.
The content of invention
The purpose of this invention is to provide a kind of block of bow collector of electric locomotive gyrocompassing platform, it can solve the stable technical matters of block of bow collector of electric locomotive by actv..
The objective of the invention is to realize through following technical scheme, is technical matters to be solved is isolated harmful motion of electric locomotive top board, reduces the loss of pantograph, contact wire, and improves current carrying quality.The technical scheme that the technical solution problem adopts is to be employed in four angle cross line directions of broken line type platform substrate by entad arranging limiting device, oil-pressure damper and air bellow outward respectively successively; Air bellow and oil-pressure damper are located between electric locomotive top board and the platform substrate; Limiting device is installed on the electric locomotive top board; The gyrocompassing device constitutes by being contained in two gyros that are symmetrical in the Y axle on the X axle and being contained in two gyros that are symmetrical in the X axle on the Y axle, and pantograph is installed on the platform substrate through four insulators.The gyrocompassing platform is made up of two parts, makes broken line type in order to save the space substrate.First is a vibration reduction platform, and it is contained on four angles of substrate, is symmetrical in X axle and Y axle; Constitute by four air bellows, four oil-pressure dampeies and four limiting devices; Their upper end is installed on the substrate, and the lower end is installed on the electric locomotive top board, crosses four jiaos of cross line directions and arranges.The limiting device restricting substrate moves in the scope of safety.The advantage of air bellow is to regulate the rigidity that air pressure changes air bellow; Make pantograph on the section circuit that is moved, reach best effectiveness in vibration suppression on the Z direction; And metal spring can only change different springs and regulate rigidity, and this is an advantage of selecting air bellow for use.Another effect of vibration reduction platform is the degree of freedom that motion is provided for the gyrocompassing device.Second portion is the gyrocompassing device, and it is symmetrical in two gyros of Y axle and is contained in two gyros formations that are symmetrical in the X axle on the Y axle by being contained on the X axle.With four gyros is in order to reduce height, and reserves the substrate midway location and through four insulators pantographs are installed.Gyro has approved product to select for use, and its rotor is high speed rotating in the cavity that is evacuated, and it is less to rotate consumed energy in a vacuum, because rotating speed high energy produces bigger directed moment.The moment of four gyros is not rotated substrate and pantograph around the X axle, also do not rotate around the Y axle, reaches directed purpose.The vibration reduction platform of composition such as air bellow, oil-pressure damper reduces the vibration of vertical, reduces to rotate the adverse effect to pantograph with gyro.
The effect that the present invention is compared with prior art useful is to make pantograph be in the not mode of operation of off-line: reduce loss and improve current carrying quality.
