Description

I-shaped high-strength conductor rail for high-speed rail line

Technical Field

The utility model relates to an I-shaped high-strength conductor rail for a high-speed rail line.

Background

Conductive rails (also known as power rails or third rails) are used in rail transit systems to transfer power to rail vehicles; the conductor rails are determined by the power requirements of the rail vehicle and the need to improve the safety and efficiency of the overall power system. The following three types of power rails are mainly used worldwide: a power rail similar to that disclosed in the tomas edison patent made of solid steel; power rails comprising a steel rail profile and two extruded aluminium profiles bolted to a steel rail network, this design being referred to in the industry as a "composite rail"; and an aluminum rail with a stainless steel cover. The conductor rail is made of solid steel section or the combination of aluminum section and steel section, and both the high conductivity and the light weight of metal are utilized.

At present, a conductive rail for an urban rail transit system is usually formed by directly covering C-shaped stainless steel on an alloy aluminum rail, two sides of the conductive rail are extruded or welded together, and due to the fact that the contact surface of the stainless steel and the alloy aluminum rail is large, a gap is easily generated between the stainless steel and the alloy aluminum rail after long-term use, the conductive effect of the conductive rail and a conductive boot is reduced, and the overall quality of the conductive rail is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects of the prior art and provides an I-shaped high-strength conductor rail for a high-speed rail line.

The utility model provides a I-shaped conductor rail that excels in for high-speed railway line, includes main part, screw rod and face guard, the face guard constitute by middle part, left part, right part, the left and right both ends at the top of main part all be equipped with the face guard groove, the bottom of left part, right part respectively with face guard groove joint, left part, right part on be equipped with the screw rod hole that a plurality of equidistance was arranged, the downthehole piece that all is equipped with of screw rod promotes the piece, promote the piece all link to each other with the movable block through the spring, screw rod bottom run through the left and right both sides of main part, screw rod hole in proper order to offset with promoting the piece.

As a further improvement, the mask groove consists of a main mask groove and a moving block groove.

As a further improvement, the size of the moving block groove is equal to that of the moving block.

As a further improvement, the screw hole is matched with the size of the screw.

As a further improvement, the mask is made of stainless steel.

As a further improvement, the main body is made of aluminum.

Has the advantages that:

this device promotes the piece through the screw rod, presses the movable block to the movable block recess in, not only can prevent horizontal removal, also can prevent vertical removal, realizes that the face guard is fixed, can effectually prevent that the face guard is not hard up, increases the fixed stability of face guard for the joint strength of face guard and main part increases, simple structure, and the operation is fixed convenient, and it is convenient to change, convenient to overhaul.
