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 move 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 drive drive rack 46 to move, and drive rack 46 will drive the 4th fixing axle
4th fixing axle 42 of 42 movements, movement will drive winding wheel 30 to move, and winding wheel 30 will drive steel wire rope 32 to move, steel
Cord 32 will drive baffle 36 to 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 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 has 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
The internal thread that will be opened on it with taper support wheel 23 at this time is bored under the externally threaded mating reaction in drive shaft 24
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, it is anti-to reach
The purpose that only train skids.
In conclusion the above embodiment is not the restricted embodiment for being the present invention, all those skilled in the art
On the basis of the substantive content of the present invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as this
The protection domain of invention.
