Abstract
It is a kind of safe end end of New concept railroad rail road that can prevent vehicle from going out blind siding, avoiding derailment accident from occurring the present invention relates to the end end of the blind siding in rail track, particularly blind siding.Technical scheme and principle are, block stake (1) connection dynamic rail (3), when vehicle (4), which is crashed into, blocks stake (1), dynamic rail (3) can be driven to be moved together with vehicle (4), rail bridge (2) can accept load in dynamic rail (3) and the middle of quiet rail (6), the frictional resistance that dynamic rail (3) is subject to when being slided on sleeper (5) can cause vehicle (4) to slow down and stop quickly, it is to avoid the generation of derailment accident.
Description
Technical field
It is that one kind can prevent vehicle the present invention relates to the end end of the blind siding in rail track, particularly blind siding
Go out blind siding, the safe end end of New concept railroad rail road for avoiding derailment accident from occurring.
Background technology
The blind siding of China railways is numerous, currently in order to preventing vehicle from going out blind siding and occurring derailment accident, mostly uses
Car lug is installed at end end and adds the methods such as damper, the shortcoming of this method is that volume is big, complicated, takes track length
Long, the adaptability to different weight, friction speed vehicle is poor.
The content of the invention
Short a pair rail of blind siding most minor details is referred to as " dynamic rail ", other rail and is referred to as " quiet rail " by the present invention；Technical scheme
It is to disconnect the connection of dynamic rail and quiet rail, installed in the end of dynamic rail and block stake, vehicle crash blocks stake car to when blocking
Impact energy pass to dynamic rail, promote dynamic rail simultaneously move, the friction being subject to using dynamic rail when sleeper moves up dynamic
Resistance is to cut down, until offsetting the impact kinetic energy of vehicle, causing vehicle deceleration and stop quickly, it is to avoid the hair of derailment accident
It is raw.
The beneficial effects of the invention are as follows the generation that can be prevented effectively from vehicle derailing accident, length that is simple in construction, taking track
Degree is short, strong to the vehicle compatibility of different weight, friction speed.
Further illustrated below in conjunction with accompanying drawing.
Brief description of the drawings
Description of the invention has 4 width accompanying drawings.
Fig. 1 is the state that rail vehicle drives to railway blind siding terminal position.
Fig. 2, Fig. 3 and Fig. 4 are the states after rail vehicle is blocked.
In figure, 1. block stake, 2. rail bridges, 3. dynamic rails, 4. vehicles, 5. sleepers, 6. quiet rails.
Embodiment
Illustrate the present invention with reference to the accompanying drawings and examples.
The present invention is constituted by blocking stake 1, rail bridge 2, dynamic rail 3, sleeper 5, quiet rail 6 etc..
The structure of embodiment one as shown in Figure 2, blocks the connection dynamic rail 3 of stake 1, one end of rail bridge 2 connects quiet rail 6, another
End had not only contacted with each other with dynamic rail 3 but also relative can slided, stick together in parallel to each other.
Operation principle is, when vehicle 4, which is crashed into, blocks stake 1, and blocking stake 1 can drive dynamic rail 3 to be moved together with vehicle 4,
It is sleeper 5, so when dynamic rail 3 is slided on sleeper 5, by very that the top of dynamic rail 3, which carries the gravity of vehicle 4, lower section,
Big frictional resistance, this resistance in turn can by block stake 1 pass to vehicle 4, cause vehicle 4 slow down and quickly stopping under
Come, it is to avoid the generation of derailment accident.The major function of rail bridge 2 is to lose support energy when dynamic rail 3 is moved away from quiet rail 6, at the two
The centre portion of power accepts load.Here sleeper 5 refers to sleeper, concrete crosstie and track bed etc..
The structure of embodiment two as shown in Figure 3, blocks the connection dynamic rail 3 of stake 1, and one end connection dynamic rail 3 of rail bridge 2 is another
End had not only contacted with each other with quiet rail 6 but also relative can slided, stick together in parallel to each other.
Operation principle is identical with embodiment one.
The structure of embodiment three as shown in Figure 4, blocks the connection dynamic rail 3 of stake 1, rail bridge 2 is fixedly mounted on sleeper 5,
And sticked together in parallel to each other with dynamic rail 3 and quiet rail 6 respectively.
Operation principle is identical with embodiment one.
