The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
A kind of magnetic suspension train power collector is used metal-impregnated carbon slide, and said metal-impregnated carbon slide is 1.2～1.8g/cm by density
3Porous carbon article is soaked copper through high-pressure smelting and is made.
The electrical resistivity of said metal-impregnated carbon slide≤5 μ Ω m, density 2.5～3.0g/cm
3, Shore hardness>=80, rupture strength>=70.
The bottom surface of said metal-impregnated carbon slide is carried out sandblast/spray copper and is handled.
As depicted in figs. 1 and 2, a kind of magnetic suspension train power collector comprises a base 2, and above-mentioned metal-impregnated carbon slide 4 is installed on the said base.
Two relative sides of said metal-impregnated carbon slide are the dip plane, make its cross-sectional plane be trapezoidal, have the metal-impregnated carbon slide mounting groove on the said base; The dip plane of one side of said mounting groove and metal-impregnated carbon slide one side is suitable; Opposite side is suitable through the dip plane of a wedge shape briquetting and metal-impregnated carbon slide opposite side; Said wedge shape briquetting 1 is fixing with base 2 through bolt 3, and the both sides of said base are fixed with safe edge 5 through screw 6.
Be provided with steel sheath 7 between said metal-impregnated carbon slide 4 and the base 2.
Base is a steel matter; The one, metal-impregnated carbon slide is supported and is able to and install; Make this power collector that good stiffness and intensity arranged; Unlikely metal-impregnated carbon plate fractures and waits the contingency generation when guaranteeing the work of this device, and the 2nd, can play the effect of conduction current, the electric current of slide plate collection will conduct to lead through it again.In addition, the wedge-shaped design of one of which end cooperates briquetting to make the installation, fixing and change and become very convenient of slide plate.4 diameter 8mm holes of slide plate base are used for this power collector is installed on the pantagraph current collector.
Since this power collector when work will with the power rail contact friction, so can receive friction force effect from the parallel orbit direction.For prevent this application force make slide plate gradually slippage break away from base, backplate before and after therefore having increased in the base both sides.Before and after backplate a little more than the slide plate baseplane, but be lower than the slide plate spacing line that weares and teares.When the spacing line of the approaching wearing and tearing of slide plate degree of wear, can avoid backplate to be worn like this.
Metal-impregnated carbon slide is 1.2～1.8g/cm by density
3Porous carbon article is soaked copper through high-pressure smelting and is obtained, and the final physical performance is electrical resistivity≤5 μ Ω m, density 2.5～3.0g/cm
3, Shore hardness>=80, rupture strength>=70; Because the inherent characteristic of carbon component in the material; Therefore this material has good self-lubricating property, can effectively reduce self and to the abrasion of mill material, and the copper of dipping can significantly improve its current capacity and strength of material.Porous carbon article makes required metal-impregnated carbon slide through after high-pressure smelting soaks copper through machinework, and the metal-impregnated carbon slide bottom surface will carry out sandblast/spray copper and handle (contact resistance that such processing can reduce itself and sheath).Then steel sheath is arrived its metal-impregnated carbon slide press fit arrangement behind spray copper through edging machine (also can handle through warding off tin more afterwards, the contact resistance that further reduces carbon piece and steel sheath increases its assembling firmness simultaneously).Steel sheath plays a protective role to the carbon piece, can prevent that metal-impregnated carbon slide from damaging by pressure to break up, and can bear stronger external force, is convenient to assemble with miscellaneous part.
Following table 1 is used to explain beneficial effect of the present invention for the present invention and prior art products condition of service contrast on homemade magnetic suspension train.
