Embodiment Construction
[0013] Below the present invention is further described in conjunction with the embodiment in the accompanying drawings: figure 1 Among them, the main body is a C-shaped aluminum rail 2, which is composed of a C-shaped aluminum rail 2 and a C-shaped stainless steel 8 to form a C-shaped perforated steel-aluminum composite rail 1. The left side of the C-shaped aluminum rail 2 has two upper and lower round edges 7, two The J-shaped steel belt 3 wraps on the round edge 7, and after the weld seam 5 is cooled, two J-shaped steel belts 3 are tightly hugged to the round edge 7, and the C-shaped stainless steel 8 and the C-shaped aluminum rail 2 are combined into one. The C-shaped aluminum rail 2 on the inner side of the weld 5 is provided with a hole 4 for passing cooling water. The two ends of the hole 4 are tapped as screw holes, and the water pipe joint is screwed on to make the cooling water flow rapidly in the hole 4, and the welding is carried away to the The excess heat on the ...

The invention relates to a C-type aluminum composite conductor rail with holes, and belongs to equipment for urban mass transit power supply. The left side, the upper round edge (7) and the lower round edge (7) of a C-type aluminum rail (2) are mainly coated with C-type stainless steel (8) formed by welding two J-type steel strips (3), the holes (4) allowing cooling water to pass through are formed in the C-type aluminum rail (2) on the inner side of a welding line (5), a middle connecting plate (9) or a mounting plate (11) can be placed in an empty groove (6) of the C-type aluminum rail (2), and a movable seat (13) can move or rotate in a base (14). The C-type aluminum composite conductor rail and a current collector have good sliding contact and matching performance under the condition that the steering radius of a magnetic suspension vehicle is small and the side rolling angle of the magnetic suspension vehicle is large, the rigidity of the C-type aluminum rail (2) cannot be reduced by welding of the J-type steel strips (3), linearity is good, and the parallelity of a line curve and a magnetic suspension rail F is good. The C-type aluminum rail (2) is large in superficial area, good in heat radiation performance and high in transmitted current.
Description
technical field [0001] The utility model relates to a C-shaped steel-aluminum composite conductive rail with holes, which belongs to equipment for power supply of urban rail transit. Background technique [0002] Before the present invention was made, in the power supply system of the third rail and the fourth rail of urban rail transit in the prior art, for example, the three-way high-strength steel-aluminum composite conductive rail with the patent number of 201020281928.9 was only applicable to the stainless steel contact surface located on the horizontal plane, It is not suitable for the stainless steel contact surface to be located on a vertical plane, and its center of gravity is far away from the bottom surface of the aluminum rail. When the two L-shaped stainless steel strips are welded together with the cylinder, the welding heat will anneal the aluminum profile, reduce the rigidity of the steel-aluminum composite rail, increase the deflection, and reduce the power ...
