Core-inlaid high manganese steel frog structure

Abstract

A core-inlaid high manganese steel frog structure includes a high manganese steel frog body and an inlaid core. The high manganese steel frog body includes a swing track connecting section, a frog central section and a frog-and-track connecting section. The wing track connecting section and the frog-and-track connecting section are respectively arranged on front and rear ends of the frog central section. A mounting groove for cooperatively mounting the inlaid core is arranged in front of the frog central section. The high manganese steel frog body and the inlaid core are detachably connected. The high manganese steel frog body and the inlaid core are detachably connected, which facilitates replacement of vulnerable parts, saves cost, and meets user requirements. The material and production procedure for the high-manganese steel frog body can be different from those for the inlaid core, which helps further improve the performance of the inlaid core.

         4 . The core-inlaid high manganese steel frog structure of  claim 2 , wherein the rear end surface of the inlaid core is inclined from top to bottom and from inside to outside; an angle is formed 2° to 4° between the rear end surface of the inlaid core and vertical direction. 
     
     
         5 . The core-inlaid high manganese steel frog structure of  claim 3 , wherein the rear end surface of the inlaid core is inclined from top to bottom and from inside to outside; an angle is formed 2° to 4° between the rear end surface of the inlaid core and vertical direction. 
     
     
         6 . The core-inlaid high manganese steel frog structure of  claim 1 , wherein first bolt holes are arranged along length direction of the mounting groove at intervals; first bolt mounting holes corresponding to the first bolt holes are arranged on lower end surface of the inlaid core; the inlaid core and the steel frog body are fixedly connected by bolts. 
     
     
         7 . The core-inlaid high manganese steel frog structure of  claim 2 , wherein first bolt holes are arranged along length direction of the mounting groove at intervals; first bolt mounting holes corresponding to the first bolt holes are arranged on lower end surface of the inlaid core; the inlaid core and the steel frog body are fixedly connected by bolts. 
     
     
         8 . The core-inlaid high manganese steel frog structure of  claim 3 , wherein first bolt holes are arranged along length direction of the mounting groove at intervals; first bolt mounting holes corresponding to the first bolt holes are arranged on lower end surface of the inlaid core; the inlaid core and the steel frog body are fixedly connected by bolts. 
     
     
         9 . The core-inlaid high manganese steel frog structure of  claim 6 , wherein an anti-rotation shim and a spring gasket are arranged between the bolt and the high manganese steel frog body. 
     
     
         10 . The core-inlaid high manganese steel frog structure of  claim 2 , wherein arc transitions are respectively arranged between left and right sides of the upper connecting section and the upper end surface of the upper connecting section, and between left and right sides of the upper connecting section and the upper end surface of the low connecting section. 
     
     
         11 . The core-inlaid high manganese steel frog structure of  claim 2 , wherein a width of a read end of the upper end surface of the upper connecting section is set to be 60 mm to 110 mm. 
     
     
         12 . The core-inlaid high manganese steel frog structure of  claim 2 , wherein left and right sides of the mounting groove are respectively arranged with a flangeway; after the lower connecting section is mounted into the mounting groove, left and right side contours of the upper end surface of the lower connecting section are respectively set to coincide with a center line of the bottom of the flangeway. 
     
     
         13 . The core-inlaid high manganese steel frog structure of  claim 11 , wherein left and right sides of the mounting groove are respectively arranged with a flangeway; after the lower connecting section is mounted into the mounting groove, left and right side contours of the upper end surface of the lower connecting section are respectively set to coincide with a center line of the bottom of the flangeway.
