Description

Technical Field

[0001] This utility model relates to the field of rail transit turnout technology, specifically a double-hole rail guard structure for turnouts. Background Technology

[0002] Because fixed frogs contain a "hazardous space," guard rails must be installed to prevent train wheels from entering the wrong direction and causing accidents when passing through the frog. These guard rails act on the back of the wheels to guide them safely through the "hazardous space." Traditional guard rails use channel steel guard rails, which are divided into two types: one is a detachable guard rail structure formed by connecting the guard rail and guide rail with spacers and guard rail bolts; the other is a welded fixed guard rail structure, where the guard rail is welded to the guide rail. The impact between the wheel and the rail, as well as the repeated rolling and sliding of the wheel, requires the guard rail and guard rail pad to have sufficient connection strength to ensure the stability of the frog and guard rail. The detachable guard rail structure connects the guard rail and guide rail together with fasteners. When the impact force between the wheel and the rail is large, the impact force on the guard rail is transmitted to the guard rail bolts and guide rail, which not only affects the stability of the guide rail but also poses a safety hazard due to the breakage of the guard rail bolts, requiring frequent maintenance. Fixed guard rail structures, while simple in design, cannot be adjusted laterally or in the distance between the guard rail and the guide rail flange. Wear can only be repaired by welding, which is inconvenient and results in high maintenance costs. Utility Model Content
