Embodiment Construction

[0018] Below the present invention is further described in conjunction with the embodiment in the accompanying drawings:

[0019] exist figure 1 Among them, the right side of the aluminum rail 1 is a stainless steel groove 2, and a dovetail groove 4 is further dug out on the left side. The upper and lower lugs 5 on the right side of the aluminum rail 1 tightly embrace the flange of the stainless steel tank 2, and then lock the lugs 5 and the stainless steel tank 2 with stainless steel blind rivets to form a steel-aluminum composite conductive rail 15 through which direct current is positively charged.

[0020] exist figure 2 The middle aluminum rail 1 is combined with the first two lugs 5 and turned 14° to the outside, and the image 3 After the inner side surface of the stainless steel tank 2 is close to the top surface 10 of the aluminum rail 1, the inner slope 8 of the stainless steel tank 2 with an angle of 30° coincides with the inner slope 8 on the aluminum rail 1. At...

Abstract

The invention relates to a steel and aluminum composite conductor rail with a dovetail groove and belongs to equipment for urban mass transit. The steel and aluminum composite conductor rail with the dovetail groove is characterized in that the dovetail groove (4) is formed in the left side of an aluminum rail body (1), inward inclined faces (8) of 30 degrees are arranged on the upper side and the lower side of the top face (10) of the right side of the aluminum rail body (1), and two supporting lugs (5) on the outer side of the top of the aluminum rail body (1) are provided with groove bottoms (6) and middle ditches (7). A connecting plate (11) of a middle connector is provided with a dovetail-shaped top (12) which can be embedded in the dovetail groove (4). Two dovetail-shaped tops (19) of an insulation support (17) can be arranged on a straight flow positive electricity composite rail body (15) and a back flow negative electricity composite rail body (16) in a sleeved mode, and thus stainless steel contact faces of two steel and aluminum composite conductor rails are made to be located in the same vertical plane.

Description

technical field [0001] The utility model relates to a steel-aluminum composite conductive rail with a dovetail groove, which belongs to equipment for urban rail transit power supply. Background technique [0002] Before the present invention was made, in the third rail power supply system of urban rail transit in the prior art, for example, a steel-aluminum composite conductor rail with a patent number of 200720005867.1, or an inner-wrapped steel-aluminum conductor rail with a patent number of 201220305047.5, they all only Used where the stainless steel contact surface is in the horizontal plane. For occasions such as maglev vehicle power supply or subway using "four-rail" power supply, the third rail (DC positive) and the fourth rail (return negative) are required to be arranged side by side on the same side of the locomotive. The above-mentioned existing steel-aluminum composite conductive rails cannot Ensure that its stainless steel contact surfaces are in the same verti...
