Description
Technical field
The present invention relates to rail technology field, a kind of automatic toggle mechanism for rail vibration damping stone.
Background technology
Along with China rail technology development, rail be broadly divided into high ferro rail, motor-car rail, rail,
Ferrum rail, due to being on the increase of rail quantity, the quantity of rail maintenance staff also gets more and more, and existing rail is safeguarded
It is broadly divided into and checks device for rail, prune and remove in the middle of rail both sides protection trees, the crowded vibration damping stone pushing away rail both sides and rail
Miscellaneous etc., but there is following defect in existing rail maintenance mode: due to meeting when high ferro, motor-car, train, subway move on rail
Produce the biggest vibration force, in order to reduce vibration force, generally lay a large amount of stones in rail both sides and reach the purpose of vibration damping, but
Being as the growth of time, the stone of rail both sides can slowly slide to both sides along with vibration force, and effectiveness in vibration suppression is deteriorated, it is therefore desirable to
Stone is pushed into rail both sides by human at periodic intervals again, but exists and need manually to push stone, and it is long to squeeze the time that pushes away, and squeezes and pushes away speed
Slowly, squeezing and push away weak effect, work efficiency is low.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of automatic toggle mechanism for rail vibration damping stone, permissible
Solve that existing rail maintenance mode exists that automaticity is low, work efficiency low, needs manually squeeze and push away stone, crowded push away the time
