Abstract
The utility model relates to a waved expansion joint for a steel-aluminum composite rail, belonging to a power supplying apparatus for rail transportation. The waved expansion joint mainly adopts the following structure: a current compensator consisting of a waved copper busbar (3) and a copper bar seat (4) is connected in parallel with an assembly of a steel-aluminum composite rail left body (1), a steel-aluminum composite rail right body (2) and a splice bar (5). The copper bar (3) is formed by waved copper sheets with thickness less than 0.1mm in a laminating way. The waved expansion joint for the steel-aluminum composite rail can not only transmit currents, but also tolerate the change of the length of the steel-aluminum composite rail on a line. When the waved copper bar (3) is in conduction, relative sliding friction, electric sparks and electrolytic corrosion do not exist, seizure is avoided, the reliability is high, the technology is simple, and the manufacturing is easy. The waved expansion joint for the steel-aluminum composite rail is small in longitudinal rigidity as well as sliding starting force.
Description
Technical field
The utility model relates to the expansion pipe of the compound rail waveform of a kind of steel aluminium, belongs to the equipment of track traffic to electric locomotive power supply usefulness.
Background technology
Before the utility model is made, the expansion pipe of steel-aluminum conductor rail relies on the waist moving contact of fish plate and the compound rail body of I-steel aluminium to transmit partly electric current mostly, a current compensator also in parallel also transmits another partly electric current by moving contact, for example the expansion pipe in the patent No. ZL200820006292.x Alternating Current Power Supply rail device comes to this, the easy galvanic corrosion of sliding contact surface is easily killed.And the current compensator in the bellows expansion joint of the compound rail of patent No. ZL200920178441.5 steel aluminium can directly transmit the electric current of compound rail clearance for expansion two ends of steel aluminium in the past, but this utility model requires to adopt copper bellows, the technology difficulty of the many ripples of multilayer big, yield rate is low.
The utility model content
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, current compensator can directly be transmitted the electric current of compound rail clearance for expansion two ends of steel aluminium in the past without moving contact, but good manufacturability, the yield rate height is made the high expansion pipe of a kind of durability and reliability.
The technical scheme that the invention for solving the technical problem adopted is: the current compensator of expansion pipe is made up of waveform copper bar 3 and copper bar seat 4, and waveform copper bar 3 is to be coincided by the corrugated scale copper of multilayer to form.Current compensator is installed on the reverse side of the compound rail surface stainless steel of steel aluminium, and its left end links to each other with the compound rail of steel aluminium left side body 1, and right-hand member links to each other with the right body 2 of the compound rail of steel aluminium.Left and right sides fish plate 5 is kept the globality of expansion pipe by the two side waists of flexible fastening at the compound rail of steel aluminium.The electric current of the compound rail clearance for expansion of steel aluminium L two ends, some moving contact transmission between fish plate and compound rail left side body 1 of steel aluminium and right body 2, most electric current directly transmission between compound rail left side body 1 of steel aluminium and right body 2 through waveform copper bar 3 and copper bar seat 4.
Compared with the prior art the utility model has the following advantages:
1, expanding with heat and contract with cold, during the expansion pipe gap change, serving as that the main current compensator two end length that constitute change thereupon with waveform copper bar 3; But two ends conduct electricity all the time, and no slide relative friction can not produce electro spark, no galvanic corrosion, can not kill, and reliable, the life-span is long.
2, the processing technology of waveform copper bar 3 is simple, the yield rate height; The waveform expansion pipe of the compound rail of whole steel aluminium is made easily.
3, the longitudinal rigidity of waveform copper bar 3 slip tripping force little, expansion pipe is little, and is little to the support and the anchor knot support antagonistic force of the compound rail of steel aluminium on the circuit, the system reliability height.
Description of drawings:
Fig. 1 is observed the utility model main structure chart from the side.
Fig. 2 is the birds-eye view of the utility model Fig. 1.
Fig. 3 is the A-A cutaway view of the utility model Fig. 1.
The specific embodiment:
The embodiment of following the utility model in conjunction with the accompanying drawings is further described:
In Fig. 1, the compound rail of steel aluminium is divided into left body 1 and right body 2, and current compensator is positioned at the compound rail of steel aluminium top, and its corrosion-resistant steel contact surface is positioned at the bottom, and two ends of waveform copper bar 3 respectively have a copper bar seat 4 to link to each other with right body 2 with the left body 1 of the compound rail of steel aluminium respectively.
In Fig. 2, copper bar 3 undulate curves.The left end of the compound rail of steel aluminium left side body 1 links to each other with the tens of meters compound rails of steel aluminium, the right-hand member of the right body 2 of the compound rail of steel aluminium links to each other with the tens of meters compound rails of steel aluminium, when about each compound rail of steel aluminium of tens of meters when in climate change, expanding with heat and contract with cold, gap L between left side body 1 and the right body 2 changes thereupon, the waveform copper bar 3 length respective change of current compensator, the radian of copper bar 3 each corner changes, in order further to reduce rigidity, copper bar 3 adopts multi-layered thickness to fuse less than the spot welding that coincides behind the bending forming in same pair of mould respectively of the scale copper of 0.1mm, owing to be configured as corrugated in advance, when the longitudinal expansion masterpiece of the compound rail of steel aluminium was used in waveform copper bar 3 two ends, the antagonistic force of copper bar 3 was just much smaller.
In Fig. 3, scale copper happen frequently the copper bar 3 that comes by bolt clip on copper bar seat 4, and copper bar seat 4 is bolted on the upper bottom surface of the compound rail of steel aluminium.About two fish plates by bolt clip on two side waists of the compound rail of I-steel aluminium, spring washer at these bolt two ends only plays spring, make fish plate keep the resilient clamp state to the compound rail of steel aluminium, and what open on the compound rail of steel aluminium is not the hole, garden, but elongated slot, in order to left body 1 or the right body 2 energy relative slippage of fish plate, produce the clearance for expansion L of numerical value with temperature Change with the compound rail of steel aluminium.
Some in the 4800A electric current on the body 1 of the compound rail of a steel aluminium left side through about two fish plates 5 pass to the right body 2 of the compound rail of steel aluminium, this is through allosome contact electric current transmitted; Another part electric current directly passes to right body 2 through electrical alignment device and waveform copper bar 3 from the compound rail of steel aluminium left side body 1, and this is a kind of direct conduction pattern.Make the transition resistance of the transition resistance at the two ends of electrical alignment device own less than the compound rail left side body 1 of steel aluminium and right body 2 and fish plate fabricate block, the electric current that passes through from the electrical alignment device is just greater than the electric current that passes through from the fish plate fabricate block, and is just bigger through the reliability of expansion pipe transmission current.The length variations of the compound rail of steel aluminium on the circuit has not only been transmitted electric current but also has been contained in the expansion pipe of the compound rail waveform of steel aluminium.
