The novel steel-aluminum composite contact rail is reasonable in design, has the characteristics of compact structure, good electric conductivity, long service life, saving of materials, safety and reliability, and the like, and can be widely applied to urban railway construction.
Description
Technical field
The utility model belongs to track traffic device field, especially a kind of novel steel-aluminum conductor rail.
Background technology
In urban track traffic, steel-aluminum conductor rail has become the dominant direction of city rail development with advantages such as its good conductivity, safety factor height, low, the disposable power supply distance of maintenance cost are long, easy for installation.Existing steel-aluminum conductor rail mainly adopts U section bar or C section bar and aluminium rail to be combined with each other, the problem of its existence is: 1, the thermal expansion distortion owing to stainless steel and aluminium differs greatly, Planar Compound, part are compound to be difficult to firmly, therefore, destroy the compound uniformity of steel aluminium, influenced the electric conductivity of steel-aluminum conductor rail; Simultaneously, the aluminium alloy extrusions sectional area adopts " worker " font etc. and depth-width ratio example bigger more, and the sectional area when making equivalent material is less, material usage is more, causes the raising of cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, conduct electricity very well and can save the novel steel-aluminum conductor rail of material.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of novel steel-aluminum conductor rail, constitute by aluminium rail and stainless strip, stainless strip is coated on the aluminium rail, described aluminium rail is " king " word shape, described stainless strip comprises two J type stainless strips, article two, the curved end of J type stainless strip is embedded into the recess of two sides, aluminium rail upper end, and the welding ends of two J type stainless strips links together by welding manner.
And the radian of the curved end of described J type stainless strip is 180 ° and its radius of curvature and ratio≤3 of material thickness.
And the end face of the welding ends of described J type stainless strip is greater than the cross section of J type stainless strip, and the lower end of the welding ends of J type stainless strip is embedded in the upper groove that aluminium rail upper surface is shaped on.
And described aluminium rail upper surface and soffit central authorities are shaped on upper groove and low groove respectively.
And described aluminium rail adopts circular transition and the total height of aluminium rail sectional area, wide ratio to approach 1.
And, be filled with conductor material on the contact surface between described aluminium rail and the stainless strip.
And described conductive material is conductive paste or conducting powder.
Advantage of the present utility model and good effect are:
1, to adopt two radians be 180 ° and its radius of curvature to this conductor rail and the J type stainless strip of ratio≤3 of material thickness is coated on the aluminium rail of " king " font by welding manner, form novel steel-aluminum conductor rail, because stainless steel is heated indirectly less than aluminium and aluminium rail by the temperature arrising caused by friction distortion, after guaranteeing that conductor rail is subjected to temperature arrising caused by friction, structure is tightr, electric conductivity is better, and the locomotive operation frequency further improves, and transport power is strengthened.
2, the end face of the welding ends of two of this conductor rail J type stainless strips is greater than the cross section of J type stainless strip, thisly increased weld strength by strengthening the bonding area mode, prolonged composite contact rail application life.
3, this conductor rail is filled with conductor material on the contact surface between aluminium rail and the stainless strip, can fill up the untight defective of mechanical compound contact by the filled conductive material, further guarantees the electric conductivity of conductor rail.
4, the aluminium rail of this conductor rail circular transition of employing itself and the total height of aluminium rail sectional area, wide ratio approach 1, thereby make the sectional area maximization, saved material, have reduced cost.
5, the utility model is reasonable in design, has compact conformation, conducts electricity very well, long service life, saving material, characteristics such as safe and reliable, can be widely used in during city rail builds.
Description of drawings
Fig. 1 is the structural representation of steel-aluminum conductor rail.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described.
A kind of novel steel-aluminum conductor rail, as shown in Figure 1, constitute by aluminium rail 2 and stainless strip, the aluminium rail is " king " word shape, promptly cave inward in the both sides, upper end of I shape aluminium rail, aluminium rail circular transition of employing itself and the total height of aluminium rail sectional area, wide ratio approach 1, thereby make the sectional area maximization, upper surface and soffit central authorities at the aluminium rail are shaped on upper groove 3 and low groove 5 respectively simultaneously, and the low groove of aluminium rail is convenient to install and increased the rigidity of aluminium rail; Stainless strip comprises two J type stainless strips 1, article two, the radian of the curved end of J type stainless strip is 180 ° and its radius of curvature and ratio≤3 of material thickness, article two, J type stainless strip is coated on the aluminium rail compound for one, its coating mode is: the curved end of two J type stainless strips is embedded into the recess of two sides, aluminium rail upper end, article two, the welding ends of J type stainless strip links together by welding manner, the end face of the welding ends of J type stainless strip is greater than the cross section of J type stainless strip, its lower end is embedded in the upper groove of aluminium rail, article two, J type stainless strip has increased weld strength by strengthening bonding area, has prolonged composite contact rail application life.
In order to increase the electric conductivity of steel-aluminum conductor rail, can also on the contact surface between aluminium rail and the stainless strip, be filled with conductor material 4, this conductive material can be conductive paste or conducting powder, can fill up the not tight deficiency of mechanical compound contact by the filled conductive material, guarantee the electric conductivity of conductor rail.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the specific embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
