Problems solved by technology

[0003] See also figure 1 and figure 2 , the existing steel-aluminum composite conductor rails include riveting type and welding type, but due to the composite process requirements of riveting or welding type, the width of aluminum rail after composite is inconsistent with the actual effective surface width of stainless steel strip. When the installation limit of line equipment is small, it cannot better meet the requirements

Embodiment 1

[0030] See image 3 , the embodiment of the present invention provides a special-shaped steel strip, the steel strip has a π-shaped cross section, and mainly includes a steel strip body 1 and two supporting legs 2, and the two supporting legs 2 are symmetrically located below the steel strip body 1, And the outer sides of the two supporting legs 2 are provided with circular arc grooves 3 along the length direction of the steel strip.

[0031] Further, the first tooth grooves 4 are evenly distributed on the outside of the lower end of the support leg 2 along the length direction of the steel strip, and the first tooth grooves 4 communicate with the circular arc grooves 3 .

[0032] Further, the first alveolar 4 is any one of triangle, rectangle and trapezoid.

[0033] The steel strip is integrally formed by hot rolling, which improves production efficiency.

Embodiment 2

[0035] See Figure 4 , the embodiment of the present invention provides a special-shaped steel strip, the steel strip has a π-shaped cross section, and mainly includes a steel strip body 1 and two supporting legs 2, and the two supporting legs 2 are symmetrically located below the steel strip body 1, And the outer sides of the two supporting legs 2 are provided with circular arc grooves 3 along the length direction of the steel strip.

[0036] Further, second tooth grooves 5 are evenly distributed on the lower surfaces of both sides of the steel strip body 1 along the length direction of the steel strip.

[0037] Further, the second tooth groove 5 is any one of triangle, rectangle and trapezoid.

[0038] It should be noted that the steel strip can not only be integrally formed by hot rolling to improve production efficiency; of course, it can also be formed by other forming methods.

Embodiment 3

[0040] See also image 3 and Figure 5 , the embodiment of the present invention provides an "I"-shaped steel-aluminum composite conductive rail, including an "I"-shaped aluminum rail 6 and a steel belt 7, which is characterized in that the two sides of the rail top of the aluminum rail 6 are symmetrically made There are two grooves 8, and the outer walls of the two grooves 8 have circular arc protrusions 9 symmetrically along the length direction; the cross section of the steel strip 7 is π-shaped, including the steel strip body 1 and two supporting legs 2; The two supporting legs 2 are symmetrically located below the steel belt body 1, and the outer sides of the two supporting legs 2 have arc grooves 3 along the length direction of the steel belt 7; the steel belt 7 is buckled on the rail top of the aluminum rail 6, and the two The two supporting legs 2 are respectively inserted into two grooves 8, and the arc protrusions 9 are embedded in the arc grooves 3 by extruding the...

Abstract

The invention discloses a special-shaped steel belt and a steel aluminum composite conductor rail. A steel belt cross section is of a pi-shaped structure, and the special-shaped steel belt comprises asteel belt body and two supporting legs; and the two supporting legs are symmetrically located below the steel belt body, and arc grooves are formed in the outer sides of the two supporting legs in the length direction of the steel belt. The special-shaped steel belt is used for the steel aluminum composite conductor rail, the width of a stainless steel belt is the same as the width of an aluminum rail, so that the effective contact surface width of the stainless steel belt and a collector shoe is increased, the effective current collection surface proportion is increased, reliable current collection of the collector shoe is guaranteed, and meanwhile, the standard requirements of the stainless steel belt and aluminum rail tensile resistance in the circuit direction and the standard requirements of the stainless steel belt and aluminum rail pulling resistance in the vertical circuit direction of the composite conductor rail are met.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, and in particular relates to a special-shaped steel strip and a steel-aluminum composite conductive rail. Background technique [0002] The steel-aluminum composite conductive rail is a power supply rail in the urban rail transit traction network, which is a whole composed of stainless steel strips and aluminum rails on the contact surface. [0003] See also figure 1 and figure 2 , the existing steel-aluminum composite conductor rails include riveting type and welding type, but due to the composite process requirements of riveting or welding type, the width of aluminum rail after composite is inconsistent with the actual effective surface width of stainless steel strip. When the installation limit of line equipment is small, it cannot better meet the requirements. Contents of the invention [0004] In order to solve the above-mentioned problems in the prior art, the present inven...
