Abstract
The utility model involves conductive rail technology field, especially a welding steel aluminum composite conductive rail with I-shaped aluminum rail and stainless steel bands. The stainless steel bands are two J-shaped stainless steel bands. Grooves are in the lateral face of the I-shaped aluminum rail at the upper end. Two J-shaped stainless steel bands are in the upper plane and two upper lateral faces. The J-shaped stainless steel bands are bended and beset in the grooves in upper lateral face of the I-shaped aluminum rail. The two J-shaped stainless steel bands are welded with the I-shaped aluminum rail on the upper plane. The utility model has long joint surface of stainless steel bands and aluminum rails. The stainless steel bands contract when cooled down after welding, so that the stainless steel bands and the aluminum rails combine closely. The transitional resistance is low. The rolled stainless steel is in microstate with good mechanical properties and wear resistance and long service life of conductive rails.
Description
Technical field
The utility model relates to the conductor rail technical field, especially a kind of welded steel-aluminium composite conducting rail.
Background technology
Traditional conductor rail is to adopt low-carbon steel material to make.What adopt as the 3rd rail of Beijing Metro and Tianjin Underground is exactly the dead-soft steel conductor rail.Also adopt at the beginning of last century developed countries be the dead-soft steel conductor rail by the 3rd rail mode initial stage of using.For a transmission distance strengthening conductor rail, improve be subjected to the stream condition, reduce mechanical wear and electrocorrosion, the raising economic and social benefit, a kind of novel conductive rail---steel-aluminium composite conducting rail has appearred the end of the seventies in last century, because of its good conductivity, current capacity is big, easily install, wear resistant corrosion resistant, the life-span is grown and is extensively adopted by developed countries.
Using under the same material situation, the complex form of steel and aluminium has determined the in-use performance of conductor rail, existing complex form has riveted type and co-extrusion pressure type, " a kind of steel-aluminium composite conducting rail " disclosed as Chinese patent CN200320109736.X, as shown in Figure 2, Chinese patent CN03262580.4 discloses " steel-aluminium composite conducting rail ", these two kinds of steel-aluminium composite conducting rails all belong to the riveted type steel-aluminium composite conducting rail, this riveted type steel-aluminium composite conducting rail is the steel band cross section to be curved the C type embed two grooves on the plane on the aluminium rail, form " rivet " structure in the side pressurization, adopt the compound mode of this riveted joint that the trend that steel band is upwarped is arranged, easily form the gap between steel band and aluminium rail, cause contact resistance to increase.The co-extrusion pressure type steel-aluminium composite conducting rail that China's 2003 the 4th phases " the city rail is led traffic study " magazine is introduced, as shown in Figure 3, the compound of this conduction rail steel aluminium is: in squeezing dies steel band after cleaning and aluminium body are squeezed into firm metallurgical binding under the technological parameter of regulation, this metallurgical binding mode forms by the effect of heat and pressure in the crumpling process, steel and aluminium contact surface do not have the gap, but high temperature is influential to the steel band performance in co-extrusion process, the steel band mechanical characteristics is reduced, aluminium also can only be as air-cooled condition, squeezing dies is easy to wear and form rail body dimensional discrepancy, the machinery of co-extrusion pressure type steel-aluminium composite conducting rail material, electric property is poor, and the life-span is short.
Summary of the invention
In order to overcome the deficiency of existing steel-aluminium composite conducting rail aspect of performance, the utility model provides a kind of welded steel-aluminium composite conducting rail, this welded steel-aluminium composite conducting rail not only steel aluminium in conjunction with closely, and the machinery of steel aluminium, good electric property.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of welded steel-aluminium composite conducting rail, have " worker " font aluminium rail and stainless steel band, stainless steel band is two " J " type stainless steel bands, two sides, " worker " font aluminium rail upper end are fluted, article two, " J " type stainless steel band is coated on plane and two upper sides on the aluminium rail, the curved end of " J " type stainless steel band is embedded in the groove of " worker " font aluminium rail upper side, and two " J " type stainless steel bands are welded to connect the junction on plane on " worker " font aluminium rail.
The beneficial effects of the utility model are: welded steel-aluminium composite conducting rail of the present utility model, since stainless steel band and aluminium rail in conjunction with face length, the trend that makes stainless steel band embrace is tightlyer arranged in the time of the welding heat cooling, stainless steel band and aluminium rail are in conjunction with tight, transition resistance is little, material microstate behind the rolling stainless steel band, mechanical property, resistance to abrasion are good, and the conductor rail life-span is long.
