Embodiment Construction
[0009] Below in conjunction with accompanying drawing and embodiment the utility model is further described.
[0010] combine Figure 1 to Figure 2 The basic structure and specific embodiments of the invention can be seen. The elastic stone removal device of the locomotive bogie is installed on the end of the locomotive bogie to remove obstacles on the track. It has a base frame 1 and an elastic stone removal arm 2. It is fixed on the base frame 1; the elastic rock removal arm 2 has an elastic cavity structure with a curved middle part.
[0011] In this embodiment, the base frame and the elastic rock removal arm are fastened together by bolts on the connecting plate. The structure of the elastic stone ejector adopts a plate-welded box structure to reduce the weight of the elastic stone ejector. The elastic rock removal arm 2 is suspended and fastened on the base frame 1 through an adjustable fixing mechanism. In this example, the adjustable fixing mechanism is connected by ...

The invention discloses an elastic stone deflector for an engine truck, which is arranged on the end part of the engine truck to remove a barrier on a rail. The elastic stone deflector comprises a pedestal 1 and an elastic stone deflecting arm 2, wherein the elastic stone deflecting arm 2 is suspended and fastened on the pedestal 1 through an adjustable fixing mechanism; and the elastic stone deflecting arm is an elastic cavity structure with bent middle part. The elastic stone deflector can greatly reduce the root stress of the stone deflector, and greatly improve the speed of a stone bounced off the rail, thereby ensuring safe running of a high speed train.
Description
Technical field [0001] The invention relates to the field of manufacturing dynamic obstacle removal equipment for railway locomotives, especially high-speed locomotives in operation. Background technique [0002] The stone remover is an obstacle removal device installed on the end of the locomotive bogie, which is used to remove obstacles on the track so that the locomotive can pass safely. During the operation of the locomotive, the stone ejector will collide with objects on the rail surface, resulting in frequent damage to the stone ejector. And along with the raising of train running speed, present stone ejector all adopts inelastic rigid structure, like this, on the one hand stone ejector is often subjected to violent impact in operation, causes the frequent damage of stone ejector, has promptly increased maintenance cost, and To a certain extent, it affects the safety and stability of train operation; on the other hand, due to the vibration of the stone ejector during ...
