It is corresponding with the installment state of anti-drop block 14, if anti-drop block 14 is spun upside down 180 degree, can describes it as
" L " shape.
Specifically, lateral part 14-1 is lagging, and, to erect baffle plate, both are by a monoblock high intensity material for vertical section 14-2
Material is processed, and is integral type structure, for example, can adopt the materials such as steel, ferrum, alloy and carbon fiber, according to metal material then
Its tensile strength and yield strength can be made to meet higher requirement by modifier treatment.
For the ease of installing, lateral part 14-1 is provided with the both sides of width and is formed by the wing plate 14-3 for stretching out
Mounting seat, the thickness of wing plate 14-3 is less than lateral part 14-1, about 1st to four/2nd of lateral part 14-1 thickness point
One of, shown in figure be 1/3rd, top surface and the top surface of lateral part 14-1 of wing plate 14-3 are generally aligned in the same plane, from indulge
When observing to the thickness direction of part 14-2, anti-drop block 14 is in " T " font on the whole, when observing from top view, whole anti-
The top surface of de- block 14 is in smooth rectangle (or square).

Block face 14-6 contacts with track 16 carry out spacing.
Fig. 7 is refer to, after Fig. 7 further develops for derailing, the relative position schematic diagram of each several part shown in Fig. 3.
When derailment occurring further develops, wheel 3-1 is possible to continue to sink, and now, the top surface of track 16 can be embedded in
Indent position 14-7 on the 14-2 lower surfaces of anti-drop block lateral part, is together carried out by lateral part 14-1 and longitudinal component 14-2
Spacing, wherein longitudinal component 14-2 continuation restriction car bodies are traversing, and lateral part 14-1 can then limit car body and continue to move down, then
Act on plus the friction eceleration on direct of travel, at most vehicle can effectively be limited in three dimensions, and, indent
The radian of position 14-7 is consistent with the radian of 16 top surface of track, can avoid damage to track.
Additionally, from fig. 6 it can be seen that the indent position 14-7 of lateral part 14-1 is not complete with the top surface of track 16
Full consistency from top to bottom, both have staggered certain distance Δ L in the horizontal, traversing due to derailing indent position 14-7 closer to
Inner side, and track is then closer to outside.So, during derailing is developed to state shown in Fig. 7 from the state shown in Fig. 6,
Under the draw of track 16, can be by car body outwards " retracting " so as to reverse traversing trend, so as to significantly more efficient
Suppress traversing.
On the premise of derailing safety device protects the functional requirement of vehicle off-line in satisfaction, with the dress after vehicle off-line
Putting the most rationally carries out structure design for condition with rail contact position so as to minimum to the security implication of track, while optimization
Overall dimensions so as to which satisfaction prevents the intensity requirement of vehicle off-line, and mode with bolts to be arranged on below axle box, position
Within vehicle gauge of the locomotive, its simple structure, it is easy for installation, take up room little, stop surface is away from lateral wheel face, rail level distance
Safe and reasonable is set, in normal state, not with rail contact, normal vehicle operation is not affected, only after vehicle derailing
With rail contact, can suppress to derail trailing wheel to continuing traversing and sidewindering well, effectively suppress derailing rear vehicle attitude to enter one
Step deteriorates or topples.
