Description
Technical field
The present invention relates to railway technology fields, in particular to a kind of track protective device.
Background technique
Tramcar is generally all layed in the street, and with surface road traffic is less separates, not proprietary right of way.Rail
Electric car track switch is generally embedded to below ground, and when on road surface, casting concrete and vehicle are run, the sundries such as the rubble on road surface are easy
It drops on slider bed platen, if cleared up not in time, is likely to result in slider bed platen and is corroded, card when will cause switch when more serious
Firmly tongue makes vehicle can not normal passageway.
Summary of the invention
The present invention is directed to solve at least one of the technical problems existing in the prior art or related technologies.
For this purpose, one aspect of the present invention proposes a kind of track protective device.
In view of this, an aspect of of the present present invention proposes a kind of track protective device, comprising: one end of cover board, cover board can
Turningly connect the wall of track；Test section, for detecting whether vehicle runs to the pre-determined distance of track；Driving
Portion, connecting cover plate, for driving cover board to rotate；Controller is separately connected test section and driving portion；Wherein, vehicle is run to pre-
If when in distance range, controller controls driving portion movement, and then cover board is driven to be folded to above wall；Vehicle is run to default
When except distance range, controller control driving portion movement, and then drive cover board expansion until cover board the other end set up it is in-orbit
The stock rail in road deviates from the one end on ground.
A kind of track protective device provided by the invention includes: cover board, test section, driving portion and controller.Wherein, track
It is provided with rail switch, rail switch includes stock rail, tongue, wall and slider bed platen, wherein slider bed platen is separately connected base
This rail and wall, slider bed platen, stock rail and wall limit installation cavity jointly, and tongue is located in installation cavity.By rationally setting
The connection structure of cover board is set, the wall so that one end of cover board is movably connected, in this way, when vehicle is run to pre-determined distance range
Except when or when carrying out road surface casting concrete, cover board expansion is until the other end of cover board rides upon the stock rail of track deviates from
The one end on ground, so that cover board is located above tongue, cover board plays the role of obstructing the installation cavity and external environment, so that installation
Chamber is sealed, and slider bed platen is not invaded by sleet at this time, is not accumulated by impurity pollutions such as sandy soil, rubbles, so that corrosion be avoided to slide
The case where table plate, occurs, tongue mobile smoothness and stability when ensure that switch, and then ensure that rail switch just
It is often used；When vehicle is run to pre-determined distance, cover board is folded to above wall, so that stock rail and tongue are not covered
Plate covering, therefore, tongue can be driven to be moved by switching machine at this time, to guarantee the normal operation of vehicle.By rationally setting
Folding and unfolding for cover board is set, so that effectively preventing in the case where guaranteeing conventional use demand of the vehicle to rail switch
Sundries and sleet in external environment are stained slider bed platen, improve safety when vehicle crosses trouble, extend product
Service life.
Specifically, when vehicle is run to pre-determined distance, test section transmits signal to controller, controller control
Driving portion movement, and then cover board is driven to be folded to above wall, then controller transmits a signal to vehicle again；When vehicle run to
