Detailed description of the invention
Embodiment in the present invention is by reference to the accompanying drawings further described below:
In Fig. 1, conductive bodies aluminium rail 2 is E font, and middle middle projection 6 becomes the horizontal stroke in the middle of E word, and the cavity of E word inside forms a fork groove 5.The left side of Fig. 1 is stainless steel tank 3, first curved 90 °, its upper and lower two angles, the tip is not scratched on again or 30 ° of downwarps, and the trough rim of this secondary bending of stainless steel tank 3 makes two journal stirrups 7 of aluminium rail 2 greatly strengthen the constrained force of stainless steel tank 3, and binding force is larger in the horizontal direction to make steel and aluminium.There is the hypotenuse of 15 ° at E shaped steel aluminium composite conducting rail 1 Er Ge angle, the left side, be convenient to inwardly bore rivet hole perpendicular to this hypotenuse, stainless steel self-plugging rivet 4 further links up the crimp of journal stirrup 7 and stainless steel tank 3 with the body of aluminium rail 2, stainless steel tank 3 is compound more firm with aluminium rail 2, and it is less more stable that steel aluminium contacts resistance.
In Fig. 2,12 ° of the each outside upsets of two, 2 left side of aluminium rail journal stirrup 7 before compound.The inside groove innermost of journal stirrup 7 is groove root 8, in steel combined with aluminum manufacturing line, first pair of upper lower pressure wheel forces journal stirrup 7 inwardly to rotate 8 ° around groove root 8, second pair of upper lower pressure wheel forces journal stirrup 7 further inwardly to rotate 4 ° around outer fissure 9, the 3rd pair of left and right pinch roller makes journal stirrup 7 around further inwardly rotation of septal fossula 10 from right to left, force on journal stirrup 7 from septal fossula curve to be left adjacent to the outside of stainless steel tank 3 crimps, also make the gap between inner side and aluminium rail 2 bodies of stainless steel tank 3 crimps less.Fig. 5 is the partial enlarged drawing of Fig. 2 upper left corner journal stirrup 7, and the cavity between aluminium rail 2 and journal stirrup 7 is like the front half body of bird, and beak tip is groove root 8, is septal fossula 10 on bird pileum, and 9 of outer fissures are above groove root 8.Groove root 8, the setting of septal fossula 10 and outer fissure 9 can make journal stirrup by predetermined path rotation, makes the inner side of journal stirrup 7 be adjacent to the crimp of stainless steel tank 3, and manufacturability is reasonable, and aluminum is without unrelieved stress.
Fig. 3 is the drawing in side sectional elevation of center coupling 11.The left side of figure is E type composite conductor rail of steel and aluminum 1, and the right is end fishplate bar 12.The fork groove 5 of aluminium rail 2 overlaps with the jaw 13 of end fishplate bar 12.The termination of every aluminium rail 2 has 3 M12 screws staggered.The long end fishplate bar 12 of a 400mm is placed at the interface place of two composite conductor rail of steel and aluminums of long 15m, bores 6 Φ 13 holes above it, with 14 and 2 overbolts 15 of 4 lag bolts by two composite conductor rail of steel and aluminums and end fishplate bar mechanical and electric on link up.Be the power rail that reaches hundreds of meters or tens of kilometers longitudinally connect with expansion pipe and end bends etc.Middle projection 6 on aluminium rail 2 is main bearing positions of center coupling, and E type composite conductor rail of steel and aluminum 1 is many with the contact surface of end fishplate bar 12, and area of contact is large, and contact resistance is little, and the characteristic that conducts electricity is good.
Fig. 4 is direct current and the backflow composite conductor rail of steel and aluminum drawing in side sectional elevation in installation place.Upper left side is the steel-aluminium composite conducting rail 1 of DC supply, it in the middle of the left side, is the steel-aluminium composite conducting rail 16 that refluxes and conduct electricity, composite conductor rail of steel and aluminum 1 and 16 sections are all E font, profile is the same, just the middle projection sectional area of composite conductor rail of steel and aluminum 16 is less than the middle projection 6 of composite conductor rail of steel and aluminum 1, thereby the sectional area ratio composite conductor rail of steel and aluminum 1 of composite conductor rail of steel and aluminum 16 is little by 17%, the same satisfied current requirements that refluxes and conduct electricity, can save 17% aluminium section bar.The insulating part that middle two fork supports 17 are polycarbonate or glass-felt plastic, the upper left side of two fork supports 17 is upper jaws 18, two forks of upper jaw 18 and the fork groove of E type composite conductor rail of steel and aluminum 1 match.It is little that the center of gravity of E type composite conductor rail of steel and aluminum 1 turns radius with respect to the Hui of jaw 18, thereby rotor inertia is little, good stability.The same lower jaw 19 near two fork supports 17 of center of gravity of lower left backflow composite conductor rail of steel and aluminum 16, easy for installation, reliable and stable, make the left side corrosion-resistant steel contact surface of upper and lower two composite conductor rail of steel and aluminums be positioned at the perpendicular parallel with locomotive running gear center, make pantagraph current collector on locomotive one in front and one in back respectively with the corrosion-resistant steel contact surface moving contact of two composite conductor rail of steel and aluminums, complete the current delivery from the rectifier at traction power supply station to locomotive engine, ensure that locomotive electric current in movement does not interrupt.Fig. 4 right side and below are metallic supports 21, two fork supports are fixed on traveling rail or the other ad-hoc location of girder construction by insulator 20 through middle upper part, thereby make DC supply E type composite conductor rail of steel and aluminum 1 and backflow composite conductor rail of steel and aluminum 16 be arranged in parallel at one on the other locomotive side below, implement the power supply to locomotive pantagraph current collector.Two composite conductor rail of steel and aluminums are installed on the ground by metallic support through the double insulation of two fork supports 17 and insulator 20, thereby ground insulation is good.Without stray current, two composite conductor rail of steel and aluminums adopt same insulation casing to do safety precaution, thereby E type composite conductor rail of steel and aluminum electric supply installation not only economy but also safety.
