Background technology
Before the utility model was made, at the compound rail of the 3rd rail electric power system employing steel aluminium of prior art middle orbit traffic, the compound rail of its expansion pipe place steel aluminium cut into two sections or three sections, contacts conduction with the fish plate slide relative.Current compensator of expansion pipe returning apparatus increases conductive section.The several of current compensator also contact conduction by slide relative between the part in addition.For example the expansion pipe in the patent No. ZL200820006292X Alternating Current Power Supply rail device only depends on moving contact to make electric current by expansion pipe.After moving contact conducted electricity process for a long time, the generation of unavoidable electro spark made the contact surface galvanic corrosion, and reliability reduces in the course of time.
Technology contents
The purpose of this utility model is that the expansion pipe that overcomes the compound rail of above-mentioned steel aluminium only depends on the moving contact conduction and the shortcoming of contact surface galvanic corrosion, improves durability and reliability.
The technical scheme that the invention for solving the technical problem adopted is: cut 400mm by line of centers longitudinally with electro spark as the compound rail of a steel aluminium of expansion pipe primary member, two ends cut laterally with 45 ° of difference, the compound rail of steel aluminium is disconnected, become left and right sides varicosity, be aided with the body of the formation joints such as two aluminium matter fish plates of length.Left and right sides varicosity is with the mid point Rotate 180 ° symmetry of longitudinal centerline, and respectively in a 400mm insied width half of the compound rail of raw steel aluminium only, and the top is 45.The copper bellowss of the many ripples of employing multilayer etc. are as current compensator, and are in parallel with the body of expansion pipe.Can expand with heat and contract with cold with the compound rail of steel aluminium on the circuit and automatically change in gap in the varicosity of the left and right sides, electric current then passes to the other end through bellows and fish plate from an end.
Compared with the prior art the utility model has the following advantages:
Expand with heat and contract with cold, during the expansion pipe gap change, the copper bellows of the many ripples of multilayer is that the length of main current compensator two ends that constitute changes thereupon; But two ends conduct electricity all the time, and no slide relative friction can not produce electro spark, no galvanic corrosion, reliable, the life-span is long.
2, the copper bellows current compensator longitudinal rigidity of the many ripples of multilayer reduces greatly, and the slip tripping force of expansion pipe is little, and little to the support and the anchor knot support antagonistic force of the compound rail of steel aluminium on the circuit, system reliability improves.
3. weather is the coldest, when the expansion pipe gap reaches 150mm, left and right sides varicosity does not vertically disconnect, about overlap 250mm, it is more much smaller than the existing compound rail expansion pipe of other steel aluminium with the reduction of the compound rail contact surface of steel aluminium that shoegear in the electric locomotive slips over moment of the present utility model, electro spark obviously reduces, performance improvement.

The specific embodiment
The embodiment of following the utility model in conjunction with the accompanying drawings is further described:
In Fig. 1, it is main adopting the copper bellows of the many ripples of multilayer, is aided with support, connects cover etc. and constitute current compensator 2, and its two end is separately fixed on the left and right sides varicosity of expansion pipe body 1 with bolt.The two constitutes in parallel on electric.From the electric current of the left varicosity input of expansion pipe body 1 respectively through the bellows of fish plate 3 and current compensator 2 by after enter expansion pipe body 1 right varicosity spread out of.Copper bellows employing multilayer thin-walled copper sleeve coincides to be placed in the horizontal tool and injects high-pressure liquid medium to inner chamber, forms the bellows of a plurality of node.Under the identical situation of cross-sectional area, be significantly smaller than the bellows stiffness of individual layer heavy wall copper sleeve moulding by the rigidity of the bellows of multilayer thin-walled copper sleeve moulding.Owing to require the expansion pipe gap of the compound rail of steel aluminium to reach 100mm to 150mm, and the only several millimeters of each node elastic telescopic amount of bellows, so require the bellows with a plurality of node, even several bellowss are together in series with connecing to overlap, to meet total clearance for expansion amount requirement.
In Fig. 2, current compensator 2 is positioned at the upper bottom surface of the compound rail of steel aluminium, and the following contact surface that does not influence the compound rail of steel aluminium contacts with shoegear and slides.The stage casing 400mm of expansion pipe, the whole compound rail of steel aluminium is cut into left and right sides varicosity 4 and 5, added by two to reach the many fish plates about 3 of 1mm and clamp.Two ends of fish plate respectively have 2 pairs of bolts.About two on bolt respectively has one pair of flat gasket and wave spring washer, and the wave spring washer of this moment uses as spring.Different Bolt Tightening Force squares can make fish plate 3 pairs of left and right sides varicosities 4 in the left and right sides with 5 different gripping powers be arranged.The M16 bolt adopts the moment of torsion of 15NM can guarantee good electric contact performance substantially.And this moment, gripping power was far smaller than the longitudinal expansion power of the compound rail of steel aluminium on the circuit, so left and right sides varicosity relative displacement longitudinally.
In Fig. 3, birds-eye view has clearly illustrated that the structure of expansion pipe body 1: horizontal center line is the longitudinal centerline of the compound rail of steel aluminium among the figure, the steel aluminium rerail of expansion pipe place longitudinally line of centers with the seam of the long 400mm of electro spark cutting, two of seam with 45 ° outwards cutting the compound rail of steel aluminium is disconnected become left and right sides varicosity 4 and 5, be aided with reach 1m many constitute the body 1 of expansion pipe than Changyu tailgate 3 and bolt, wave spring washer etc.Gap delta in the left and right sides varicosity 4 and 5 can be expanded with heat and contract with cold with the compound rail of steel aluminium on the circuit and reduced or increase.The electric current of the compound rail of steel aluminium on the circuit of the left side passes to left varicosity 4 after bellows current compensator 2 and fish plate 3 pass on the right varicosity through common fish plate, passes to the compound rail of steel aluminium on the circuit of the right again.The bellows expansion joint of the compound rail of steel aluminium has not only transmitted electric current but also has contained the length variations of the compound rail of steel aluminium.
