On 36 end face of baffle；As shown in figure 13,27 one end of sand pipe is fixedly mounted on 28 lower end surface of fixed blocks, and sand pipe
27 communicate with square groove 43；As shown in Figure 10,32 one end of wirerope is fixedly mounted on 30 periphery of winding wheel, and wirerope 32 twines
It is wound on 30 periphery of winding wheel, the other end passes through the first fixed plate 8, movement hole 45, is fixedly mounted on 36 end face of baffle.
As shown in Fig. 2, the draft hitch 1 is mounted on 4 upper surface of crossbearer；As shown in figure 3, the lower end of 4 two sides of crossbearer
Face is separately mounted on 53 upper surface of axle box on two drive wheel mechanisms 5；The periphery diameter of belt pulley 15 is driving cylinder 29
1/2 times of periphery diameter；The periphery diameter that the periphery diameter of belt pulley 15 is equal to friction pulley 13 is identical.
41 original state of second spring is compressive state.
The size of the square groove 43 is identical as 35 size of first hole.
First spring 34 is compressed spring.
First directive wheel 9 is identical as 20 size of the second directive wheel.
Lubricating oil is coated between the guide groove 49 and guide block 51.
It is lubricating grease that lubricating oil is coated between the guide groove 49 and guide block 51.
Specific embodiment are as follows: the drive shaft 24 of movement will will drive driving cylinder 29 and move, and driving cylinder 29 will drive whirlpool
Coil spring 21 moves；Scroll spring 21 will be compressed, and the scroll spring 21 of compression will will drive taper support wheel 23 and move,
During scroll spring 21 compresses, as shown in figure 24, taper support wheel 23 at this time will be along the axial direction of drive shaft 24
Movement, after the threading action between taper support wheel 23 and drive shaft 24 is complete, taper support wheel 23 at this time will be with driving
It will relatively rotate between axis 24；Taper support wheel 23 will be moved in the case where driving 29 driving effect of cylinder；Friction pulley 13 will
It can be moved under the frictional force effect of rail 3；When on rail 3 there are snowy, rain and grease stain or when train climbing power not
When enough, opposite slide will occur between taper support wheel 23 and rail 3 at this time；Taper support wheel 23 at this time will be opposite
The fast speed of movement, since the periphery diameter of belt pulley 15 is 1/2 times for driving 29 periphery diameter of cylinder；Belt pulley 15
The periphery diameter that periphery diameter is equal to friction pulley 13 is identical；So the movement velocity and friction pulley 13 of belt pulley 15 at this time
Movement velocity will not opposite matching；So the belt 22 of upside will will appear the state of loosening at this time；When belt 22 occurs
When loosening, triggering block 39 at this time will be moved under the action of second spring 41 along guide groove 49；The triggering block 39 of movement will
Fixed block 40 is driven to move, fixed block 40 will will drive drive rack 46 and move, and drive rack 46 will will drive the 4th fixing axle
42 movements, the 4th fixing axle 42 of movement will will drive winding wheel 30 and move, and winding wheel 30 will will drive wirerope 32 and move, steel
Cord 32 will will drive baffle 36 and move, and baffle 36 at this time will gradually slowly movement under the action of damper rod 33；At this time
Baffle 36 on first hole 35 communicated with square groove 43, the sand in sandbox 7, which will be flowed out, flows to cone by sand pipe 27
Between shape support wheel 23 and rail 3, to reach the frictional force increased between taper support wheel 23 and rail 3, reaching prevents fire
The purpose skidded in vehicle motion process；During sand in sandbox 7 flows out, train in order to prevent at this time is had skidded
The phenomenon that occur, so reducing the linear velocity of train at this time is necessary；The linear velocity for lowering train movement will
Achieve the purpose that prevent train from skidding；Opposite movement will occur between taper support wheel 23 at this time and drive shaft 24；Institute
Under the externally threaded mating reaction on internal screw thread and drive shaft 24 that will be opened on it with taper support wheel 23 at this time, cone
The direction that shape support wheel 23 will reduce to periphery diameter reduces, in the case where 23 velocity of rotation of taper support wheel is constant,
Reduce the diameter of 23 periphery of taper support wheel at this time, it will so that the linear velocity of taper support wheel 23 reduces, to reach anti-
The only purpose that train skids.
In conclusion it is restricted embodiment of the invention, all those skilled in the art that above embodiment, which is not,
On the basis of substantive content of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as this
The protection scope of invention.
