The composite conducting rail 100 of embodiment according to a first aspect of the present invention is described below with reference to Fig. 1-Fig. 5.
As Figure 1-Figure 5, composite conducting rail 100 according to an embodiment of the present invention, including 1, two the first steel band 2 of aluminium rail
With the second steel band 3.
Aluminium rail 1 is formed as C-shaped so that the side of aluminium rail 1 is formed with opening 10a, the two sides difference relative to each other of aluminium rail 1
Fluted 10b is formed, the close mutual direction of the edge groove 10b direction, the opening 10a for being directed away from aluminium rail 1 are obliquely installed, and recessed
Slot 10b is formed as wedge groove, and two the first steel bands 2 correspond cooperation in two groove 10b.Second steel band 3 is formed as c-type
Steel band, and the second steel band 3 tool, there are two the side 31 being oppositely arranged, the second steel band 3 is withheld on another side surface of aluminium rail 1,
The above-mentioned side of each side 31 towards aluminium rail 1 extends beyond the side of the above-mentioned side of the neighbouring aluminium rail 1 of corresponding groove 10b
Wall, two sides 31 respectively with two 2 overlap joint weldings of the first steel band.
For example, as Figure 1-Figure 5, opening 10a can be formed in the downside of aluminium rail 1 and opening 10a is opened wide downward, groove
10b can be respectively formed at the left and right sides (for example, left and right sides as shown in figure 1) of aluminium rail 1, and left groove 10b and right side are recessed
Slot 10b be all formed as wedge groove and left groove 10b and right groove 10b can about aluminium rail 1 along the vertical direction (for example,
Up and down direction as shown in figure 1) extend central axis it is symmetrical, left groove 10b can by aluminium rail 1 partial left side surface to the right
Recessed formation, right groove 10b can be by the partial right side surface recessed formation to the left of aluminium rail 1, and left groove 10b and right side are recessed
Direction close mutual direction in the edge slot 10b is obliquely installed upwards, that is to say, that left groove 10b is tilted from left to right, upwards
It setting and right groove 10b right-to-left, is obliquely installed upwards, to ensure that the first steel band 2 cooperates in respective slot 10b
And with after 31 overlap joint welding of respective side, the position of the first steel band 2 fix so that the first steel band 2 is not allowed under the effect of external force

It crosses the upper side wall of respective slot 10b and each side 31 extends downward into the lower wall for being less than respective slot 10b, in order to
The overlap joint welding between side 31 and the first corresponding steel band 2 is realized, so that the first steel band 2 and the second steel band 3 are formed as
The wear-resistant coating of one entirety ensure that the service life of composite conducting rail 100.
Composite conducting rail 100 according to an embodiment of the present invention, the cross sectional shape of composite conducting rail 100 is simple, aluminium rail 1 and
Two steel bands, 3 compound tense, aluminium rail 1 will not be plastically deformed, and simplify the processing technology of composite conducting rail 100, be reduced compound
The composite pressure of conductor rail 100, the cost for facilitating the processing of composite conducting rail 100, reducing composite conducting rail 100；Pass through
By side 31 respectively with corresponding first steel band, 2 overlap joint welding, can be contacted to avoid in welding, directly with aluminium rail 1, to play
The effect of aluminium rail 1 is protected, while ensure that the quality of weld seam；The fillet weld between side 31 and corresponding first steel band 2 exists simultaneously
In cooling procedure, its welded stress there is the component on horizontal and vertical direction, can increase the second steel band 3 and aluminium rail 1 it
Between cladding power, thus fillet weld complete it is cooling after, combine even closer between the second steel band 3 and aluminium rail 1 so that composite guide
Electric rail 100 has good use reliability, ensure that the stable structure of composite conducting rail 100.
In some alternative embodiments of the invention, with opening 10a opposite side table of the groove 10b relative to aluminium rail 1
The tilt angle in face is α1, α1Meet: 5 °≤α1≤15°.For example, in the example of fig. 3, the central axis of each groove 10b with
Angle α between the upper surface of aluminium rail 11Meet 5 °≤α1≤ 15 °, so that it is recessed in correspondence to further ensure the cooperation of the first steel band 2
In slot 10b and with after 31 overlap joint welding of respective side, the position of the first steel band 2 fix so that effect of first steel band 2 in external force
Under be not easy to be extracted and be detached from and cooperate with respective slot 10b, and then improve the structural stability of composite conducting rail 100.
Optionally, the key groove of groove 10b is α2, α2Meet: α2≥2°.For example, in the example of Fig. 2-Fig. 4, it is each recessed
The upper side wall and lower wall of slot 10b moves closer to each other on the direction towards close another groove 10b, so that groove 10b
Upper side wall and groove 10b lower wall between angle α2Meet α2>=2 °, consequently facilitating the cooperation of the first steel band 2 is recessed in correspondence
In slot 10b, the installation of the first steel band 2 is facilitated, the packaging efficiency of composite conducting rail 100 is improved.
In some embodiments of the invention, as shown in figs 2-4, the first steel band 2 is adapted with groove 10b, and two
The first end 21 of one steel band 2 be arranged toward each other and the first end 21 of the first steel band 2 with a thickness of t1, the second of the first steel band 2
End 22 with a thickness of t2, the width of the first steel band 2 is h, and the key groove of the first steel band 2 is β, t1、t2, h and β meet respectively: 2mm
≤t1< t2、h≥1.5*t2,β≥2°.As a result, the first steel band 2 can be preferably adapted with respective slot 10b, guarantee
The compactness that cooperates between first steel band 2 and respective slot 10b；It ensure that the intensity of the first steel band 2, and the first steel simultaneously
There is suitable cooperation width, again such that the first steel band 2 is not easy under the effect of external force between band 2 and respective slot 10b
It is extracted and is detached from and cooperates with respective slot 10b, improve the structural stability of composite conducting rail 100.
In further embodiment of the present invention, holding tank 10c is limited in aluminium rail 1, is formed on the wall surface of holding tank 10c
There is at least one radiating groove 10d.For example, the downside of holding tank 10c is opened wide to form the 10a that is open in the example of Fig. 1-Fig. 3,
Radiating groove 10d there are five being formed on the upper wall surface of holding tank 10c, each radiating groove 10d can have on the part of holding tank 10c
The upwardly recessed formation of wall surface, holding tank 10c is interior to be suitable for setting insulating carriage, can be by composite conducting rail by insulating carriage
In orbit, in order to install, air can flow in radiating groove 10d to promote composite conducting rail 100 at this time for 100 installations
