Abstract
The invention relates to a method for installing and connecting a steel-aluminum composite rail with radiating fins, which belongs to equipment for supplying power to a third rail of urban rail transit. The steel-aluminum composite rail with the radiating fins increases the rated current by more than 1.3 times under the condition that the sectional areas of the aluminum rails are the same, reduces the temperature rise K value under continuous current and saves materials.

The main solution of the invention is realized as follows: the steel-aluminum composite rail (1) is fixed on a support (4) beside a walking steel rail by adopting a top hook (3) and a grabbing hook (2) which are staggered with a radiating fin (8) of the steel-aluminum composite rail (1) in space, and an adjacent steel-aluminum composite rail (1) is connected by adopting a fishplate (9) which can be embedded with the radiating fin (8) of the steel-aluminum composite rail (1). Compared with the prior art, the invention has the following advantages:
1. so that the steel-aluminum composite rail with the radiating fins can be installed and connected.
2. Under the condition of the same section of the aluminum rail, the rated current carrying capacity can be increased by 1.3 times.
3. The temperature rise K value under the continuous current can be reduced by more than 30 percent
4. The sectional area of the aluminum rail can be reduced by more than 30 percent.

Detailed Description
The invention will be further described with reference to the following examples in which:
fig. 1 is an installation diagram of a steel-aluminum composite rail with a heat sink. The steel-aluminum composite rail 1 is provided with a radiating fin 8, the support 4 is installed on the ground beside the walking steel rail, the top hook 3 is fixed on the side wall of the support 4 through bolts, the top hook 3 supports the left side of the steel-aluminum composite rail 1, the grab hook 2 is fixed on the top hook 3 through bolts, the grab hook 2 supports the right side of the steel-aluminum composite rail 1, and the top hook 3 and the grab hook 2 jointly fix the steel-aluminum composite rail 1 on the right side of the support 4. And a nylon sliding sheet 5 is arranged between the installation inclined plane of the steel-aluminum composite rail 1 and the top hook 3 and the grapple 2, so that the steel-aluminum composite rail 1 can slide relative to the support 4 without damaging the support 4 when the steel-aluminum composite rail is expanded with heat and contracted with cold. The top hook 3 and the grapple 2 are spatially staggered with the radiating fins 8 of the steel-aluminum composite rail 1, so that the radiating fins 8 do not interfere with the installation of the steel-aluminum composite rail 1.
Fig. 2 is a sectional view of a steel-aluminum composite rail 1 with cooling fins, wherein each side of the waist of the steel-aluminum composite rail 1 is provided with 4 cooling fins, and the two sides of the waist have 8 cooling fins 1, so that the circumference of the section of the steel-aluminum composite rail 1, which can be cooled, is increased by nearly one time compared with the case without the cooling fins, and the cooling area of an aluminum rail 6 in unit length is increased by 75%; under the condition that the sectional areas of the aluminum rails are the same, the rated current of the steel-aluminum composite rail can be increased by 30 percent; or at the same rated current the temperature rise K is only 70%. The steel-aluminum composite rail 1 is composed of an aluminum rail 6 and a stainless steel groove 7, and the stainless steel groove 7 is formed by welding a basin-shaped stainless steel and two stainless steel bars.
Fig. 3 is a connection diagram of the finned steel-aluminum composite rail 1. Two steel-aluminum composite rails 1 with the length of 15m on the left front view are connected by 4 pairs of bolts by a middle fishplate 9 and are integrated mechanically and electrically, and a plurality of third rail power supply circuits with the length of kilometers are formed. In the middle of fig. 3 is a sectional view a-a at the bolt and on the right of fig. 3 is a sectional view B-B at the fishplate 9. A pair of bolt and nuts clamp the left and right fishplates 9 on the steel-aluminum composite rail 1 in the section A-A. The fishplates on each side in the section view of B-B are respectively provided with 4 grooves with slopes to contain the radiating fins with the same slopes of the steel-aluminum composite rails, and the fishplates 9 and the radiating fins are embedded into a whole.
Fig. 4 is a sectional view of the connection of the finned steel-aluminum composite rail 1, and is also an enlarged view of a sectional view a-a in fig. 3. In the figure, a pair of bolt and nut standard parts tightly clamp the left and right fishplates 9 on the middle steel-aluminum composite rail 1 to form an intermediate joint. Because the radiating fins 8 are embedded in the grooves of the fishplates, the contact area of the fishplates and the steel-aluminum composite rails is increased by 8 times, the contact resistance is reduced by 75%, and the temperature rise k value at the middle joint is reduced by 75%.
