Fig. 3, Fig. 4 are refer to, Fig. 3 is the stereogram of derailing safety device;Fig. 4 is derailing security protection shown in Fig. 3 The side view of device;
It is in inverted " L " shape anti-drop block 14 that derailing safety device is one piece, and it can be divided into abundant lateral part 14-1 and abundant longitudinal component 14-2, longitudinal component 14-2 are perpendicular in the lower section side of lateral part 14-1, from side When face is observed, in inverted " L " shape.Certainly, used here as be inverted a word be for the structure of more convenient description anti-drop block, It is corresponding with the installment state of anti-drop block 14, if anti-drop block 14 is spun upside down into 180 degree, can describes it as " L " shape.
Specifically, lateral part 14-1 is lagging, and longitudinal component 14-2 is perpendicular baffle plate, and both are by a monoblock high intensity material Material is processed, and is integral type structure, for example, can use the materials such as steel, iron, alloy and carbon fiber, according to metal material then Its tensile strength and yield strength can be made to meet requirement higher by modifier treatment.
For the ease of installing, lateral part 14-1 is formed in the wing plate 14-3 that the both sides of width are provided with by 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 being observed to the thickness direction of part 14-2, anti-drop block 14 is on the whole " T " font, whole anti-when being observed from top view The top surface of de- block 14 is in smooth rectangle (or square).
Two dormant bolt hole 14-4 spaced apart are machined with each wing plate 14-3 respectively, for bolt hole 14-4 Quantity, do not do specific restriction herein, the difference of size and installation requirement according to wing plate 14-3, can also be three, four It is individual even more, it is also possible to only to set one.
The end portion width of longitudinal component 14-2 is less than (also may be used between body part, and the side of both sides by cambered surface 14-5 Being inclined-plane) rounding off, the medial surface of longitudinal component 14-2 is stop surface 14-6, and stop surface 14-6 is in a longitudinal direction from end Portion slopes inwardly 3 °~5 ° to root, and the angle of the inclined angle alpha for setting here is 4 °, the medial surface angle of inclination beta with track shoulder Angle it is consistent.
The lower surface of lateral part 14-1 is provided with an arc concave shape position 14-7, and its radius R is 80mm, with rail top face Radian is consistent, and to increase the contact area of anti-drop block and track head after vehicle derailing, indent position 14-7 passes through transverse part The circular arc position 14-8 rounding ofves of point 14-1 and longitudinal component 14-2 intersections are to stop surface 14-6, lateral part and longitudinal direction portion The intersection of part on-right angle for circular arc, on the one hand can eliminate stress concentration phenomenon, on the other hand can improve anti-drop block By force intensity, prevent it from obvious deformation occur at the position in stress.
Used as another form, the indent position on the lower surface of lateral part can also always transit to stopping for longitudinal component Block face 14-6, being formed together with lateral part 14-1 and longitudinal component 14-2 is in the circular arc position 14-8 of intersection can be with track The curved portion that peripheral shoulder shape matches.
Refer to Fig. 5, Fig. 6, under Fig. 5 is normally travel state, derailing safety device shown in Fig. 4 on bogie with The relative position schematic diagram of axle box, wheel and track;After Fig. 6 is for derailing, the relative position schematic diagram of each several part shown in Fig. 5.
When using, above-mentioned anti-drop block is fixed on the bottom of axle box 2 by four bolts 15, same wheel to two axle boxes lower section One anti-drop block is respectively set, left wheel and right wheel are corresponded to respectively, and positioned at the outside of wheel.Because anti-drop block is in locus Upper and wheel 3-1 and the grade part of track 16 maintain a determining deviation, therefore in normal vehicle operation, anti-drop block not with wheel And rail contact, only in derailing, just with the medial surface sliding contact of track shoulder.
For example, when train derails to the left, left side wheel is disengaged to the outside of left rail, under the axle box of right side The anti-drop block of side is contacted with right rail, and now, the distance between the anti-drop block and left rail in left side become big, are not involved in preventing De-, vice versa.
Because anti-drop block stop surface 14-6 is consistent with the inclined angle of the shoulder lateral surface of track 16, therefore both can be tight Close fits together, on the one hand can limit in the horizontal car body continue outwards it is traversing, suppress vehicle attitude further deteriorate or Topple, force of sliding friction on the other hand can be relied on the direct of travel of train, train is slowed down, reduce risk coefficient.
Fig. 5 show the primary stage of general derailment occurring or derailing, and in this case, anti-drop block only relies on it to be stopped Block face 14-6 contacts with track 16 carry out spacing.
Fig. 7 is refer to, after Fig. 7 is for derailing further development, 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 limitation car bodies are traversing, and lateral part 14-1 can then limit car body and continue to move down, then Plus the friction eceleration effect on direct of travel, at most effective limitation can be carried out to vehicle in three dimensions, and, indent The radian of position 14-7 is consistent with the radian of the top surface of track 16, 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, reverse traversing trend can be made it have, so that significantly more efficient by car body outwards " retracting " Suppress traversing.
Safety device derail on the premise of the functional requirement of protection vehicle off-line is met, with the dress after vehicle off-line Put with rail contact position the most rationally for condition carries out structure design, make its security implication to track minimum, while optimization Appearance and size, makes its satisfaction prevent the intensity requirement of vehicle off-line, and is connected by screw bolts mode installed in axle box lower section, position Within vehicle gauge of the locomotive, its simple structure, it is easy for installation, occupy little space, 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 influenceed, only after vehicle derailing With rail contact, can well suppress derailing trailing wheel to continuing traversing and sidewindering, effectively suppress derailing rear vehicle attitude and enter one Step deteriorates or topples.
