Abstract
The utility model relates to a steel-aluminum composite conductor rail for rail transit, which comprises an aluminum rail and a stainless steel coil, which is bonded to the brush surface of the aluminum rail without gaps. Mount grooves on both sides are arranged on lower end face of the H-shaped aluminum rail along the axial direction, the stainless steel coil is embedded into the mount grooves on both ends thereof, and the both sides of the lower end face of the aluminum rail are folded to obtain folded edges. Via-holes combined with the aluminum rail and filled with aluminum rail material are formed on both sides of the stainless steel coil. The utility model has simple structure, non-gap bonding of the composite steel-aluminum interface, good conductivity, large current capacity, small specific gravity, convenient assembly, high resistance to corrosion and wear, and long service life.
Description
One, technical field
The utility model relates to a kind of track traffic equipment, specifically a kind of track traffic steel-aluminium composite conducting rail.
Two, background technology
Along with developing rapidly of track traffic, more and more higher to the requirements for quality of track traffic steel-aluminium composite conducting rail.The conductor rail for supplying power that uses is made up of a matrix and a brush face usually at present, the brush face links to each other with matrix, and the brush face is made up of the abrasion resistant material, wherein, the part that forms towards matrix one side at the brush face is provided with the lath that stretches along brush face length degree direction, wherein one of each lath and brush face portion vertical long and narrow side forms a depression jointly, and it is filled by the material of matrix at least in part.The shortcoming of this structural conductive rail is: complex structure, and steel aluminium compound interface is mechanical bond, and the gap is bigger, causes that resistance increases between matrix and brush surface layer, and service life has been shortened in the corrosion aggravation.
Three, summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of track traffic steel-aluminium composite conducting rail, this steel-aluminium composite conducting rail, simple in structure, and steel aluminium compound interface is the combination of no gap, interface resistance is little, can not be subjected to corrosion infringement between binding layer, so good conductivity, current capacity are big; This steel-aluminium composite conducting rail proportion is little, easy for installation simultaneously; Withstanding corrosion, resistance to abrasion are good, long service life.
The purpose of this utility model is achieved through the following technical solutions:
A kind of track traffic steel-aluminium composite conducting rail comprises aluminium rail body and stainless steel band, it is characterized in that: seamlessly be compounded with stainless steel band on the brush face of aluminium rail body; Described aluminium rail body is " worker " font, and the both sides of its lower surface are along the mounting groove that is axially arranged with of aluminium rail body, and the two ends of stainless steel band are embedded in the mounting groove and make the both sides of aluminium rail body lower surface form bound edge; Be provided with the through hole that combines with aluminium rail body and fill by aluminium rail bulk material in the both sides of stainless steel band.
In the utility model, described aluminium rail body is made by aluminum alloy, and its both sides, lower surface are vertical edge before the assembling.
Stainless steel band presents the C type before assembling, the mounting groove of the two ends of C type and aluminium rail body is suitable.
In the utility model, aluminium rail body part material embeds stainless steel band along its length in the cooresponding through hole of quantity, thereby forms the cooresponding depression of quantity on the bound edge that aluminium rail body is bent to form.
Through hole described in the utility model can be circular port or strip shape hole, forms cooresponding circular depressed of quantity or strip shape depression on the bound edge that aluminium rail body is bent to form.
Compared with prior art, the utility model is not only simple in structure, and good conductivity, current capacity are big; Proportion is little, easy for installation; Withstanding corrosion, resistance to abrasion are good, long service life.
Four, description of drawings
Fig. 1 is a cross section structure scheme drawing of the present utility model;
Fig. 2 is the structural representation of the utility model stainless steel band.
Five, the specific embodiment
Describe a kind of embodiment of the present utility model in detail with reference to Fig. 1 and 2.
A kind of track traffic steel-aluminium composite conducting rail described in the utility model is made of aluminium rail body 1 and stainless steel band 2 two parts.Stainless steel band 2 seamlessly is compounded on the brush face of aluminium rail body.Aluminium rail body 1 is made by aluminum alloy, and the both sides of its lower surface are axially arranged with mounting groove 11 along aluminium rail body, and its both sides, lower surface are vertical edge before the assembling, this vertical edge and stainless steel band 2 compound back formation bound edges.Stainless steel band 2 is the C type before assembling, be provided with manhole 21 in the both sides of stainless steel band.Aluminium rail body 1 is " worker " font.Aluminium rail body 1 partly material embeds stainless steel band 2 along its length in the cooresponding through hole 21 of quantity, thereby forms the cooresponding depression 13 of quantity on the bound edge 12 that aluminium rail body 1 is bent to form, and finally makes the compound interface of the two be the combination of no gap.
When the utility model is made,, the two ends of stainless steel band are embedded into the mounting groove the inside of both sides, aluminium rail body lower surface and make the both sides of aluminium rail body lower surface form bound edge at first process stage; At second process stage, aluminium rail body and stainless steel band are pressed against each other as follows by means of pressure roller, promptly go up pressure roller and be pressed towards the face that is used as the collector shoe surface, the roll-in of side pressure simultaneously is to aluminium rail body two vertical edges, and side direction is pressurizeed continuously from the outside, make aluminium rail body two vertical edges form bound edge naturally, aluminium rail body part material embeds stainless steel band along its length in the cooresponding hole of quantity, thereby on the bound edge that aluminium rail body is bent to form, form the cooresponding depression of quantity, a upper support roller on originally stopping, the aluminium rail is arranged, a lower compression roller is arranged below, and before second process stage, last pressure roller presses together aluminium rail body and stainless steel band.
