Manufacturing method of producing frog and crossing assemblies for overhead contact systems

Abstract

A modular crossing assembly structure in an overhead contact system. The modular crossing assembly structure includes a plurality of rail underrunning contact segments and a body to which the plurality of these rail segments are attached, where the plurality of rail segments are connectable to an overhead conductor rail and/or overhead contact system. The plurality rail segments are securely affixed to the body by one or more connectors.

What is claimed: 
     
         1 . A modular crossing assembly structure in an overhead contact system comprising:
 a plurality of rail segments; and   a body to which the plurality of rail segments are attached,   
       wherein the plurality of rail segments are connectable to an overhead conductor rail or conductor wire. 
     
     
         2 . The module crossing assembly structure of  claim 1 , further comprising one or more connectors that securely affix the plurality of rail segments to the body. 
     
     
         3 . The module crossing assembly structure of  claim 1 , wherein the plurality of rail segments include a first rail segment, a second rail segment, a third rail segment and a fourth rail segment. 
     
     
         4 . The module crossing assembly structure of  claim 3 , wherein the first and the second rail segments are attached to one side of the body and the third and the fourth rail segments are attached to another side of the body, and wherein the first, second, third and fourth rail segments form a crossing junction. 
     
     
         5 . The module crossing assembly structure of  claim 3 , wherein each of the first, second third and fourth rail segments have a tapered end for smooth passage of collector shoe. 
     
     
         6 . The module crossing assembly structure of  claim 3 , further comprising a central alignment portion that is provided at the center of a crossing between the first, second, third and fourth rail segments. 
     
     
         7 . The module crossing assembly structure of  claim 1 , wherein the body has a guard portion to prevent inadvertent disconnect from overhead structure. 
     
     
         8 . The module crossing assembly structure of  claim 1 , wherein the body has an attachment portion for connecting the body to a special work structure of the overhead contact system. 
     
     
         9 . A modular frog assembly structure in an overhead contact system comprising:
 a plurality of rail segments; and   a body to which the plurality of rail segments are attached,   
       wherein the plurality of rail segments are connectable to an overhead conductor rail or conductor wire. 
     
     
         10 . The modular frog assembly structure of  claim 9 , further comprising one or more connectors that securely affix the plurality of rail segments to the body. 
     
     
         11 . The modular frog assembly structure of  claim 9 , wherein the plurality of rail segments include a first rail segment, a second rail segment, and a third rail segment. 
     
     
         12 . The modular frog assembly structure of  claim 11 , wherein the first and the second rail segments arc attached to one side of the body and the third rail segment is attached to another side of the body, and wherein the first, second, and third rail segments form a turnout junction. 
     
     
         13 . The modular frog assembly structure of  claim 11 , further comprising a switch connector that selectively connects the third rail segment with the first rail segment and the second rail segment. 
     
     
         14 . The modular frog assembly structure of  claim 13 , wherein the switch connector includes one or two movable linking rail segments. 
     
     
         15 . The modular frog assembly structure of  claim 14 , further comprising a reset lever that selectively controls the reset movement of the one or two movable linking rail segments,
 wherein when the reset lever is moved to a first position, the movable linking rail segments is moved laterally into one of two reset positions to connect the third rail segment with the first rail segment, and   when the reset lever is moved to a second position, the movable linking rail segment is moved laterally into the other of two reset positions to connect the third rail segment with the second rail segment.   
     
     
         16 . The module crossing assembly structure of  claim 9 , wherein the body has a guard portion to prevent inadvertent disconnect from overhead structure. 
     
     
         17 . The module crossing assembly structure of  claim 9 , wherein the body has an attachment portion for connecting the body to a special work structure of the overhead contact system.
