Equipped with rotary steering hole.Sliding block 520 is slidably disposed on guide rail 510, sliding block 520 and horizontal part 120 rotatably phase
Even.So it can be not only oriented to using back-and-forth motion of the guide rail 510 to screw rod 100, but also can be in order to described spiral
The setting of pilot hole.
In a specific embodiment of the utility model, the hand of spiral of screw 400 is spiral with spirally-guided bar 130
Direction is opposite.It can so make to realize more effectively transmission between motor 300, screw 400 and screw rod 100.
Certainly, both hand of spiral can also be identical.
Further, as Figure 1-Figure 5, the front end of snow removing 200 adjacent tracks vehicle 2 of component is set.It can so protect
Card snow removing component 200 can clear up the accumulated snow in front of travelling wheel in time, ensure that driving is reliable.
According to the snow-removing mechanism 1 for rail vehicle of one specific example of the utility model.The component 200 that removes the snow is two
A, the front end of two snow removing components 200 is close to each other and rear end is located remotely from each other.Screw rod 100 is two, two snow removing components
200 are connected by two screw rods 100 with rail vehicle 2 respectively.Two snow removing components 200 can so be utilized at the same time to track
Accumulated snow on beam 3 is cleared up, and can reduce resistance caused by the accumulated snow in front, further easy to raising snow removing effect.
Specifically, as Figure 1-Figure 5, each snow removing component 200 is removed including two that anteroposterior direction parallel interval is set
Snow brush 210.So 210 pairs of track girders 3 can be brushed using two rows snow removing to clear up, ensure every time track girder 3 when driving at the same time
Cleaned twice before and after, further improve snow removing effect.
Further, as Figure 1-Figure 5, the component 200 that removes the snow includes the rigid portion 211 being connected with screw rod 100 and sets
Flexible bristle 212 in 211 lower surface of rigid portion, when snow removing component 200 is positioned at the snow removing position, rigid portion 211 is vertical
With the distance between track girder 3 it is 150-200 millimeters on direction.It can so ensure between rigid portion 211 and the track girder
With enough safe distances.
Specifically, the bottom plate of rail vehicle 2 is equipped with mounting hole, and screw rod 100 is removably engaged in the mounting hole
It is interior.So can removably it be installed in order to screw rod 100.
Work below with reference to Fig. 1-Fig. 6 descriptions according to the snow-removing mechanism 1 for rail vehicle of the utility model embodiment
Make process.
When needing to be removed the snow, motor 300 rotates, and drives screw 400 to rotate, the level of screw 400 and screw rod 100
120 thread fitting of portion, driving screw rod 100 moves forward, while screw rod 100 drives spirally-guided bar 130 and sliding block 520 1
With moving forward, spirally-guided bar 130 drives screw rod 100 to rotate under the guiding in the spirally-guided hole, by the component that removes the snow
Above 20 upsets to track girder 3.
When that need not be removed the snow or snow removing component 20 is safeguarded, motor 300 rotates backward, and drives screw 400
