Description
Technical field
The present invention relates to a kind of intrados groove and fogging composite conducting rail, be mainly used in the electric power system of urban track traffic.
Background technology
At present; The steel-aluminum conductor rail that City Rail Transit System is used is generally C type corrosion-resistant steel and directly overlays on the alloy aluminum rail, both sides or extruding or weld together, because of corrosion-resistant steel and alloy aluminum rail contact surface bigger; Long-term use; Be easy to generate the gap between corrosion-resistant steel and the alloy aluminum rail, reduced conductor rail and the conductive effects conduction boots, thereby influenced the total quality of conductor rail.
Summary of the invention
The objective of the invention is: design a kind of track traffic steel-aluminium composite conducting rail; Not only simple in structure; And steel aluminium compound interface is the combination of no gap, and steel aluminium friction force is big, fogging; Therefore good conductivity, interface resistance are little, simultaneously a kind of steel-aluminium composite conducting rail of withstanding corrosion, wear-resistant, long service life.
In order to solve the problems of the technologies described above; The present invention provides a kind of intrados groove and fogging composite conducting rail; It it mainly be " J " type by alloy aluminum rail, cross section corrosion-resistant steel form, the form of welding in the middle of said composite conducting rail adopts, two J type corrosion-resistant steel left-right symmetric are coated on the lower surface of alloy aluminum rail and the outer arc of side; Brute force through three directions compresses, and then J type corrosion-resistant steel is carried out the centre welding; After the welding cooling, J type corrosion-resistant steel and alloy aluminum rail form and closely cooperate, and its compound interface is combined for no gap.
Said alloy aluminum rail is " worker " font; The both sides of its lower end have the groove of 8 ° of gradients, and lower end integral body is the eaves type, in the morning or in the wet weather; The fog that condenses can prevent because of condensing of water smoke steel aluminium faying face to be produced the erosion of prolonged permeation property along the landing of eaves type hypotenuse.
The lower plane that said alloy aluminum rail and J type corrosion-resistant steel are fitted has 1.7 ° angle, and after compressing through external force, this angle can make its difficult drop-off with the tensioning of J type corrosion-resistant steel.
The stainless intrados of said J type is processed with groove, and after compressing through external force, the groove of said J type corrosion-resistant steel intrados and the exterior arc surface place of said alloy aluminum rail form tight engagement, combines friction force to obtain bigger steel aluminium.
Further, after said two J type corrosion-resistant steels and the alloy aluminum rail external force through three directions compressed, the weld seam of 1.5mm was left in the centre; The centre portion of alloy aluminum rail lower end; Have the concave arc groove, in welding process, reach in the weld seam of stainless 1.5mm in the concave arc groove of complete filling alloy aluminum rail after stainless steel welding stick is dissolved by high-temperature electric arc; It is full that feasible one side is welded the weld seam of two sides shaping, guarantees that weld strength is high.If there is not the arc groove of concave end under the alloy aluminum rail, then welding may be insufficient, causes weld defect, influences weld strength.Behind the welding cooling shrinkage, the outer arc of the stainless intrados groove of J type and alloy aluminum rail can carry out secondary shrink nibble with, form mated condition more closely, make its compound interface for the combination of no gap, strengthen steel aluminium friction force and electric conductivity greatly.
Said J type corrosion-resistant steel can form solder joint and pile up after the welding of centre in corrosion-resistant steel outside face commissure, influence the surface contact of outward appearance and conduction boots.Through special milling equipment the groove of wide 10mm, dark 0.2mm is processed in the commissure, makes it and conduct electricity boots and when contacting, have good electrical conductivity and crossing ability.
