Abstract
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
Affiliated technical field
The present invention relates to rolling stock, especially express locomotive hinders manufacturing field of equipment with dynamic row in service.
Background technology
Stone deflector is mounted in the obstacle deflector on the engine truck end, is used to get rid of the obstacle on the track, makes the locomotive can safe passing.In the locomotive operation, stone deflector will bump with the object on the rail level, causes stone deflector damage often to occur.And along with the raising of train running speed, present stone deflector all adopts inelastic rigid construction, like this, stone deflector is in operation and often is subjected to violent collision on the one hand, cause the frequent damage of stone deflector, promptly increase maintenance cost, influenced the safety and the stability of train operation again to a certain extent; On the other hand, because stone deflector trembles in high-speed cruising, when bumping with the rail level obstacle, major injury often takes place in the root of stone deflector.
Summary of the invention
The stone deflector that the purpose of this invention is to provide a kind of favorable elasticity, make it to overcome the above shortcoming of prior art, structure by the appropriate design elastic stone deflector, make elastic stone deflector not only can have enough rigidity, prevent that elastic stone deflector from trembleing in high-speed cruising, guarantee the safety and the stability of train high-speed cruising, can have enough elasticity again, in collision process, can produce elastic deformation and efficient buffer, reduce the Root Stress of elastic stone deflector, and the quick bullet of rail level obstacle is left the right or normal track.
The objective of the invention is to realize by following means.
Elastic stone deflector for engine truck is installed in the obstacle that is used to get rid of on the engine truck end on the track, has a pedestal and elasticity row stone arm, and described elasticity row stone arm hangs by adjustable fixed mechanism and is fastened on the pedestal; Elasticity row stone arm is the flexible cavity structure of middle bent.
Adopt design of the present invention well to solve and damage in forecarriage stone deflector utilization process, often occurs, prolong the service life of stone deflector, and under the condition of train high-speed cruising, elastic stone deflector can play good buffer action to the high-speed crash with obstacle equally, can satisfy under the high-speed cruising condition performance requriements to stone deflector.Can significantly reduce the Root Stress of stone deflector, improve the speed that the stone bullet leaves the right or normal track significantly, guarantee the safe operation of train, especially high speed train.
Description of drawings
Fig. 1 is the three-view diagram of elastic stone deflector of the present invention.
Fig. 2 is the total figure of embodiment of the invention elastic stone deflector assembling.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Can find out the basic structure of the present invention and the specific embodiment in conjunction with Fig. 1 to Fig. 2.Elastic stone deflector for engine truck is installed in the obstacle that is used to get rid of on the engine truck end on the track, has a pedestal 1 and elasticity row stone arm 2, and described elasticity is arranged stone arm 2 and is fastened on the pedestal 1 by adjustable fixed mechanism suspension; Elasticity row stone arm 2 is the flexible cavity structure of middle bent.
In the present embodiment, between pedestal and the elasticity row stone arm by bolted on the gusset piece together.The structure of elastic stone deflector adopts the box type construction of plate welding, to alleviate the weight of elastic stone deflector.Elasticity is arranged stone arm 2 and is fastened on the pedestal 1 by adjustable fixed mechanism suspension, in this example, adjustable fixed mechanism is the multi-hole position bolted connection, elasticity row stone arm 2 is provided with gusset piece 4, the pedestal correspondence is provided with gusset piece 3, have the bolt hole of 6 M24 on the gusset piece, in use only need fastening four bolts just can satisfy requirement of strength, the mainly convenient height of adjusting stone deflector apart from rail level of residue bolt hole.
Actual verification of the present invention is improved to example with HXD2B locomotive stone deflector, in use earlier elasticity is arranged stone arm 2 and tightens together by adjustable fixed mechanism suspension, and pedestal 1 is the hollow cavity structure also, then stone deflector is installed on the framework.If in use elastic stone deflector weares and teares, can regulate the height of stone deflector by selecting bolts hole different on the gusset piece for use apart from rail level, guarantee the elastic stone deflector bottom surface apart from the rail identity distance from being about 30mm.The present invention can solve and damage often occur in forecarriage stone deflector utilization process, prolong the service life of stone deflector, and under the condition of train high-speed cruising, elastic stone deflector can play good buffer action to the high-speed crash with obstacle equally, can satisfy under the high-speed cruising condition performance requriements to stone deflector.
