Detailed description of the invention
The embodiment of the utility model in is by reference to the accompanying drawings further described below:
In Fig. 1, aluminium rail 1 the right is stainless steel tank 2, and a dovetail furrow 4 is further dug out on its left side.Upper and lower two journal stirrups 5 in aluminium rail 1 the right are tightly embraced the crimp of stainless steel tank 2, then pin journal stirrup 5 and stainless steel tank 2 with stainless steel self-plugging rivet, form the steel-aluminium composite conducting rail 15 of perfectly straight stream positive electricity.
In Fig. 2, compound the first two journal stirrup 5 of aluminium rail 1 flips to the outside 14 °, the medial surface of the stainless steel tank 2 in Fig. 3 is adjacent to after the end face 10 of aluminium rail 1, the interior inclined-plane 8 of 30 ° of the angles of stainless steel tank 2 overlaps with the interior inclined-plane 8 on aluminium rail 1, at this moment the inside application force of rolling wheel up and down on steel combined with aluminum manufacturing line forces outer inclined-plane 9 to rotate 14 ° around groove root 6 to the inside, and outer inclined-plane 9 is the level of state.After this compressing from right to left of the side wheel with 30 ° of inclined-planes on steel combined with aluminum manufacturing line makes the right-hand part of journal stirrup 5 further centered by middle ditch 7, rotate and draw close to the inside, eliminate the gap in journal stirrup 5 and stainless steel tank 2 crimps outsides, also the gap that further reduces the interior inclined-plane of stainless steel tank 2 crimp inner sides and aluminium rail 1, is compounded on aluminium rail 1 stainless steel tank 2 firmly.
Stainless steel tank 2 in Fig. 3 is by clod wash flow forming, first rolls out the oblique angle of 30 ° open and flat on steel, then 90 ° of clod washes inside 30 ° of oblique angles, becomes 15m or the long stainless steel tank 2 of 18m after calibrated.
Fig. 4 is the drawing in side sectional elevation of center coupling.The each 50mm in interface left and right of long two steel-aluminium composite conducting rails of 15m or 18m and each 150mm are outer and be positioned at the left side boring of positive middle part and attack 4 M12 tapped bore, the connecting panel middle part of long 400mm is corresponding each 4 φ 13 holes of boring also, utilize a connecting panel 11 by two 15m or the long composite conductor rail of steel and aluminum of 18m machinery and electric on couple together.Right-hand dovetail form top 12 of connecting panel 11 is sticked in the dovetail furrow 4 of aluminium rail 1, and guidance quality is good, makes two composite conductor rail of steel and aluminums in left and right by automatic aligning, has also increased the area of contact of the two, and the transition resistance between two composite conductor rail of steel and aluminums in left and right is obviously reduced.4 bolts 13 are fasteners of center coupling.
Fig. 5 is the drawing in side sectional elevation of backflow negative electricity composite conductor rail of steel and aluminum 16.This composite conductor rail of steel and aluminum is the negative pole to traction power supply station rectifier for current reflux, and its current ratio is just minimum.Therefore offer 3 lightening holes on negative electricity composite conductor rail of steel and aluminum 16, make the sectional area of its aluminium reduce 20%, be conducive to reduce costs.Stainless steel self-plugging rivet 3 on journal stirrup 5 both can make composite conductor rail of steel and aluminum in Long-term Vibration environment, keep steel aluminium contact resistance not increase, and also can solve and differ the bending problem of bringing 50% left and right because of the coefficient of expansion of corrosion-resistant steel and aluminium.
Fig. 6 is the partial enlarged drawing at journal stirrup 5 places.The groove root 6 of journal stirrup 5 and middle ditch 7 are used for improving the manufacturability of steel combined with aluminum, make aluminium there is no unrelieved stress.The cone of stainless steel self-plugging rivet 3 the inners makes its radial interference, by the crimp of stainless steel tank 2 together with journal stirrup 5 rivetings on the body of aluminium rail 1, stainless steel tank 2 and the combination reliability of aluminium rail 1 are improved.Lightening hole 14 does not affect the combination of steel and aluminium.
Fig. 7 is the cross-sectional view of positive negative electricity composite conductor rail of steel and aluminum in installation place.Top in the middle of Fig. 7 is a horizontal U-shaped insulating support 17, adopts glass-felt plastic or polycarbonate compression molding, is used for supporting two composite conductor rail of steel and aluminums, can make DC1500V 3000A electric current and metallic support 18 insulate.Metallic support 18 can fix on the ground as required, and also changeable shape is fixed on the below of girder construction.The left side of insulating support 17 respectively has a dovetail form top 19 up and down, and top can fill positive electricity composite conductor rail of steel and aluminum 15, fills below negative electricity composite conductor rail of steel and aluminum 16.Can, first by two parallel putting on the ground of composite conductor rail of steel and aluminum, put insulating support 17, after metallic support 18 installs, again two parallel steel-aluminium composite conducting rails be installed on metallic support 18 together with insulating support, use bolted.The adjacent composite conductor rail of steel and aluminum in left and right connects to center coupling with connecting panel 11 afterwards, is loaded on expansion pipe, anchor knot joint, and road fork and insulation cover cap, form " four rails " traction power supply net.
