Abstract
The utility model relates to an aluminium-sheathed dipping metal carbon slide plate for the pantograph of an electric locomotive, which adopts carbon used as a basal body. An open pore is dipped with copper alloy, the composite material of a reticular metal structure can be formed, and a dipping metal carbon body can be formed. The outside of the carbon body is coated with a metal aluminium casing, the middle part at the bottom of which is provided with a convex reinforcing rib which is provided with a square hole for fixing a special-shaped screw bolt. The bottom of the dipping metal carbon body is provided with an n-shaped ditch groove which is corresponding to the convex reinforcing rib of the metal aluminium casing. A fixed bolt is inlaid in the ditch groove of the carbon body. The dipping metal carbon slide plate overcomes the defects of the existing carbon slide plates and aluminium-sheathed carbon slide plates, such as low strength, big attrition, big resistance, inconvenient replacement, etc. The utility model simultaneously overcomes the defects of a powder metallurgy slide plate, such as big conducting wire attrition, poor self lubrication, short service life, etc.
Description
The utility model relates to a kind of electric locomotive and is flowed original paper, is used for all types of block of bow collector of electric locomotive of railway (mine).
Existing block of bow collector of electric locomotive is a lot of with the slide plate kind, metal-impregnated carbon slide is arranged, copper-base powder metallurgy slide plate, aluminium-covered carbon slider etc.These slide plates cut both ways to self wearing away of contact system lead abrasion and slide plate, Cu-base powder slide plate intensity height, but it is big to lead abrasion, though metal-impregnated carbon slide and aluminium-covered carbon slider are little to the contact system lead abrasion, but self intensity is undesirable, also has shortcomings such as the insecure and dismounting inconvenience of fixed form simultaneously.
The purpose of this utility model is to overcome the shortcoming of existing block of bow collector of electric locomotive with all kinds slide plate, provides a kind of section structure reasonable, and fixed form is firm, and dismounting is easy to maintenance, the block of bow collector of electric locomotive slide plate that self-lubricating property is good.
The technical solution of the utility model is to realize like this, a kind of block of bow collector of electric locomotive is to be matrix with carbon with aluminium bag metal-impregnated carbon slide, in open pore, immerse copper alloy, form the composite material of net metal structure, constitute the metal-impregnated carbon body, its special character is to be surrounded by the metallic aluminium shell in the outside of carbon body, be embedded on the metal-impregnated carbon body, bolt of rear end plate is installed in the groove of carbon body, the metallic aluminium shell is by the extruded aluminium section manufacturing, there is the convex reinforced rib at the middle part on the bottom, on reinforced rib, have the square opening that is used for fixing heterotypic bolt, be plane or have groove below the bottom, the bottom of metal-impregnated carbon body has shape groove corresponding with the convex reinforced rib on the metallic aluminium shell, is embedded in together, and bolt of rear end plate is the special shaped screw bolt of oblong head, the size of bolt cap is corresponding with the rectangular mouth on the metallic aluminium casing stiffening muscle, and bolt cap is bumped in square opening.The composition that immerses copper alloy consists of aluminium 10-18%, plumbous 3-5%, and antimony 3-4%, tin 4-5%, all the other are copper.
It is reasonable that the utility model compared with prior art has section structure, fixed form is firm, easy for assembly, disassembly and maintenance, self lubricity is good, and is little to all kinds of contact line conducting wire abrasion, only is 1/2nd of partial metallurgy slide plate, the intensity height of slide plate own, wear resisting property is good, and shock resistance is non-friable, and the slide plate long service life is two times on a partial metallurgy slide plate.
Now describe the utility model most preferred embodiment in conjunction with the accompanying drawings in detail:
Fig. 1 is the schematic perspective view of aluminium bag metal-impregnated carbon slide
Fig. 1-a is the carbon body
Fig. 1-b is the metallic aluminium shell

Among the figure 1, carbon body 2, groove 3, aluminium shell 4, reinforced rib 5, square opening
6, heterotypic bolt
A kind of block of bow collector of electric locomotive with the sheath metal-impregnated carbon slide as shown in Figure 1, 2, it is to be matrix with carbon, in open pore, immerse copper alloy, form the composite material of net metal structure, constitute metal-impregnated carbon body 1, its special character is to be surrounded by metallic aluminium shell 3 in the outside of carbon body 1, and metallic aluminium shell 3 is embedded on the metal-impregnated carbon body 1, and fixedly the heterotypic bolt 6 of usefulness is installed in the groove 2 of carbon body 1.Metallic aluminium shell 3 is by the extruded aluminium section manufacturing, and there is convex reinforced rib 4 at the middle part on the bottom, has the square opening 5 that is used for fixing heterotypic bolt 6 on reinforced rib 4, below the bottom for the plane or have groove.The bottom of metal-impregnated carbon body 1 has shape groove 2 corresponding with the convex reinforced rib 4 on the metallic aluminium shell 3, can be embedded in together.Bolt of rear end plate 6 is the special shaped screw bolt of oblong head, and the size of bolt cap is corresponding with the rectangular mouth 5 on metallic aluminium shell 3 reinforced ribs 4, and bolt cap is bumped in square opening.
Block of bow collector of electric locomotive is as follows with the production technology of aluminium bag metal-impregnated carbon slide:
The carbon body is squeezed into shape, sends calciner to, heat to about 1250 ℃ by certain heating gradient, sintering 24 hours, cooling was lost efficacy again, deflated, and the apparent porosity in the assurance carbon body is the key that guarantees the dipping alloy ratio about 20%.In order to guarantee the mechanical characteristics of carbon body dipping alloy tail skid, electric property and resistance to abrasion etc., the composition of the dipping copper alloy of employing consists of aluminium 10-18%, plumbous 3-5%, antimony 3-4%, tin 4-5%, all the other are copper.The carbon body is placed in the high-pressure impregnation jar,,, is forced into 9.8 * 10 then copper alloy fusion in the jar with 760 ℃ of temperature
5About Pa, keep taking-up in about 20 minutes, put into the insulation jar then, through oxygen barrier, assembling is taken out in insulation, inefficacy, cooling back, earlier the special shaped screw bolt of oblong bolt cap is installed in the square opening on the reinforced rib of aluminium shell, then the aluminium shell that has special shaped screw bolt is embedded on the carbon body of impregnating metal, aluminium bag metal-impregnated carbon slide is made in repressed shaping.
