Please refer to Fig. 3, Fig. 4, Fig. 3 is the block diagram of derailing safety device; Fig. 4 is the lateral plan of the safety device of derailing shown in Fig. 3;
Derailing safety device is one piece is inverted " L " shape anti-drop block 14, it can be divided into abundant lateral part 14-1 and abundant longitudinal component 14-2, longitudinal component 14-2 is perpendicular in the side, below of lateral part 14-1, when observing from the side, in inverted " L " shape.Certainly, the word of use inversion one is here the structure in order to convenient description anti-drop block, is corresponding with the installing condition of anti-drop block 14, if anti-drop block 14 is spun upside down 180 degree, then can describes it as " L " shape.
Particularly, lateral part 14-1 is lagging, vertical part 14-2 is perpendicular baffle plate, both are processed by a monoblock high strength material, for integral type structure, such as can adopt the materials such as steel, iron, alloy and carbon fiber, then its tensile strength and yield strength can be made to meet higher requirement by modifier treatment according to metallic material.
For the ease of installing, lateral part 14-1 is provided with the mount pad formed by outward extending wing plate 14-3 in the both sides of Width, the thickness of wing plate 14-3 is less than lateral part 14-1, be about 1/1 to four/2nd of lateral part 14-1 thickness, be 1/3rd shown in figure, the end face of wing plate 14-3 and the end face of lateral part 14-1 are positioned at same plane, when observing from the thickness direction of longitudinal component 14-2, anti-drop block 14 is on the whole in " T " font, when observing from birds-eye view, the end face of whole anti-drop block 14 is smooth rectangle (or square).
Each wing plate 14-3 is processed with respectively two countersunk-heat bolt hole 14-4 kept at a certain distance away, for the quantity of bolt hole 14-4, do not do concrete restriction herein, according to the size of wing plate 14-3 and the difference of installation requirement, can also be three, four even more, also can only arrange one.
The end portion width of longitudinal component 14-2 is less than body part, and by cambered surface 14-5 (also can be inclined-plane) rounding off between the side of both sides, the medial surface of longitudinal component 14-2 is stop surface 14-6, stop surface 14-6 slopes inwardly 3 ° ~ 5 ° from end to root in a longitudinal direction, the angle of the inclined angle alpha set here is 4 °, consistent with the angle of the medial surface angle of inclination beta of track shoulder.
The lower surface of lateral part 14-1 is provided with an arc concave shape position 14-7, its radius R is 80mm, consistent with the radian of rail top face, to increase the area of contact of anti-drop block and track head after vehicle derailing, indent position 14-7 passes through the circular arc position 14-8 rounding off of lateral part 14-1 and longitudinal component 14-2 intersection to stop surface 14-6, the intersection of lateral part and longitudinal component is circular arc and on-right angle, can be eliminated stress concentration phenomenon on the one hand, that can improve anti-drop block on the other hand is subject to force intensity, prevent it from when stressed, occurring significantly distortion at this position.
As another kind of form, indent position on the lower surface of lateral part can also transit to the stop surface 14-6 of longitudinal component always, forms the curved portion that can match with track peripheral shoulder shape with lateral part 14-1 with longitudinal component 14-2 together with the circular arc position 14-8 of intersection.
Please refer to Fig. 5, Fig. 6, Fig. 5 is under normal motoring condition, the safety device of derailing shown in Fig. 4 on bogie truck with the relative position schematic diagram of journal box body, wheel and track; Fig. 6 is after derailing, the relative position schematic diagram of each several part shown in Fig. 5.
During use, above-mentioned anti-drop block is fixed on axle box 2 bottom by four bolts 15, and same wheel below two right axle boxes respectively arranges an anti-drop block, respectively corresponding left wheel and right wheel, and is positioned at the outside of wheel.Because anti-drop block all maintains a determining deviation with the parts such as wheel 3-1 and track 16 on locus, therefore when normal vehicle operation, anti-drop block not with wheel and rail contact, only when derailing, just with the medial surface moving contact of track shoulder.
Such as, when train derails to the left, left side wheel departs from the outside to left rail, and the anti-drop block be positioned at below right-hand axis casing contacts with right rail, and now, the distance between the anti-drop block in left side and left rail becomes greatly, and do not participate in anticreep, vice versa.
Because anti-drop block stop surface 14-6 is consistent with the angle of the inclination of track 16 shoulder lateral surface, therefore both can fit together closely, can limit car body on the one hand in the horizontal continues outwards traversing, vehicle attitude is suppressed to worsen further or topple, force of sliding friction can be relied on the other hand on the direct of travel of train, train is slowed down, reduces risk factor.
Figure 5 shows that general derailment occurring or the primary stage of derailing, in this case, it is spacing that anti-drop block only relies on the contact of its stop surface 14-6 and track 16 to carry out.
Please refer to Fig. 7, Fig. 7 is after derailing further develops, the relative position schematic diagram of each several part shown in Fig. 3.
When derailment occurring further develops, wheel 3-1 likely continues to sink, now, the end face of track 16 can embed the indent position 14-7 on the 14-2 lower surface of anti-drop block lateral part, together carry out spacing by lateral part 14-1 and longitudinal component 14-2, wherein longitudinal component 14-2 continuation restriction car body is traversing, lateral part 14-1 then can limit car body to be continued to move down, add the friction eceleration effect on direct of travel, actv. restriction can be carried out to vehicle at most in three dimensions, and, the radian of indent position 14-7 is consistent with the radian of track 16 end face, can avoid damaging track.
In addition, as can be seen from Figure 6, the indent position 14-7 of lateral part 14-1 and the end face of track 16 be complete consistency from top to bottom not, and both have staggered certain distance Δ L in the horizontal, the indent position 14-7 traversing due to derailing is closer to inner side, and track is then closer to outside.Like this, derailing from the state development shown in Fig. 6 to Fig. 7 shown in state process, under the draw of track 16, by car body outwards " retracting ", reverse traversing trend can be made it have, thus actv. suppresses traversing more.
Derailing safety device is under the prerequisite of the functional requirement of satisfied protection vehicle off-line, with this device after vehicle off-line and rail contact position the most rationally for condition carries out structure design, make it minimum to the security implication of track, optimize oad simultaneously, it is made to meet the requirement of strength preventing vehicle off-line, and mode with bolts is arranged on below journal box body, within being positioned at vehicle gauge of the locomotive, its structure is simple, easy for installation, take up room little, stop surface is apart from lateral wheel face, rail level distance arranges safe and reasonable, in normal state, not with rail contact, do not affect normal vehicle operation, only ability and rail contact after vehicle derailing, derailing trailing wheel can be suppressed well to continuing traversing and sidewindering, effective suppression derailing rear vehicle attitude worsens further or topples.
Please refer to accompanying drawing 8,9,10, Fig. 8 is the structural representation that in framework, air chamber is communicated with; Fig. 9 is the structural representation of framework; Figure 10 is the A direction view of Fig. 9.
Framework comprises two curb girder 1-1, two crossbeam 1-2 between curb girder 1-1; Wherein, curb girder 1-1 is provided with the air bellow seat 1-11 for installing air bellow 7, and the main gas tank 7-1 of the air bellow 7 after installation is positioned at the inner chamber of curb girder 1-1, and crossbeam 1-2 is the solid drawn pipe structure of hollow.In addition, as shown in Figure 8, framework also comprises passage 1-6, for the cavity of the main gas tank 7-1 and crossbeam 1-2 that are communicated with air bellow 7.
As shown in Figure 8, by passage 1-6, make the main gas tank 7-1 of air bellow 7 and the cavity connects of crossbeam 1-2, then the cavity of crossbeam 1-2 can as the auxiliary chamber of air bellow 7, achieve the main gas tank 7-1 of air bellow 7 and being communicated with of auxiliary chamber, effectively make use of the inner space of framework, save as air bellow 7 installs independent cylinder, increase the gas chamber volume of air bellow 7 simultaneously, thus reduce the eigentone of air bellow 7, make air bellow 7 can keep lower and intimate equal oscillation frequency under any load, realize vibration-damping function, improve the traveling comfort of track train.
The particularly important is, find in test under high-speed cruising environment, the reason that in prior art, air bellow cushioning performance declines is, the air-tightness as the curb girder of auxiliary chamber is poor.Because curb girder is welded by steel plate splicing and is formed, and periphery exists many weld seams, and air-tightness is poor.The improvement that the present invention makes just on this basis, will have the auxiliary chamber of cavity as air bellow 7 of hollow seamless steel-tube construction crossbeam 1-2, solid drawn pipe structural perimeter does not have seam, and air-tightness is better.Therefore, compared with prior art, the auxiliary chamber air-tightness of air bellow 7 provided by the present invention is better, can meet the damping requirements of train during high speed.In addition, solid drawn pipe can elect ring cross-section as, when bearing inside or outer radial pressure, stressed comparatively even, meets the load bearing requirements of train during high speed further.
Framework can also comprise the air chamber 1-3 longitudinally arranged, and the two ends of air chamber 1-3 are communicated with two crossbeam 1-2 respectively; In addition, passage 1-6 is communicated with the main gas tank 7-1 of air chamber 1-3 and air bellow 7, to realize the main gas tank 7-1 of air bellow 7 and being communicated with of crossbeam 1-2 cavity.
This air chamber 1-3 is the structure of inner hollow, achieves being communicated with of passage 1-6 and crossbeam 1-2 cavity easily, thus the main gas tank 7-1 of air bellow 7 is communicated with auxiliary chamber by its internal cavities.On the one hand, air chamber 1-3 as auxiliary chamber together with the cavity of crossbeam 1-2, can further increase the auxiliary chamber volume of air bellow, improves the vibration-damping function of air bellow 7; On the other hand, air chamber 1-3 longitudinally arranges (being shown in accompanying drawing 10), can improve the torsional stiffness of curb girder 1-1 and crossbeam 1-2 junction, thus improves the strength and stiffness of framework.
Further, as shown in Figure 10, the two ends of air chamber 1-3 can be fixedly welded on the madial wall of corresponding crossbeam 1-2 respectively, simultaneously, as shown in Figure 8, the position that crossbeam 1-2 madial wall corresponds to air chamber 1-3 end offers crossbeam through hole 1-2-1, is communicated with air chamber 1-3 by crossbeam through hole 1-2-1, crossbeam 1-2 cavity.
In the present embodiment, air chamber 1-3 and crossbeam 1-2 madial wall are welded and fixed, and connection mode is fairly simple, sealing property is excellent, and can save other connection structure, thus realizes the lightweight of framework, therefore, the connection mode of air chamber 1-3 and crossbeam 1-2 madial wall is preferably welded to connect.But, it will be appreciated by those skilled in the art that, the connection mode of the two ends of air chamber 1-3 and the madial wall of two crossbeam 1-2 is not limited only to be welded to connect in theory, such as, air chamber 1-3 can insert at two ends crossbeam 1-2 inner chamber, and carry out sealing also passable at their interconnective positions, or also can design corresponding connection fastener.
On this basis, the bending plate that air chamber 1-3 can take the shape of the letter U for cross section, and with its open side longitudinal measure in the madial wall of curb girder 1-1, make to be connected by air chamber 1-3 between curb girder 1-1 with crossbeam 1-2.Can composition graphs 8, Figure 10 understand, the two edges of U-bend plate open side are welded in crossbeam 1-2, and passage 1-6 corresponds to the position of U-bend plate open side, to be communicated with air chamber 1-3.
In this embodiment, air chamber 1-3 is U-bend plate structure, coordinates the cavity needed for being formed with the madial wall of curb girder 1-1, on the one hand, make use of the madial wall of curb girder 1-1, can save the material forming air chamber 1-3, realize the lightweight of framework; The more important thing is, achieve being welded and fixed of curb girder 1-1 and crossbeam 1-2, to make curb girder 1-1 and crossbeam 1-2 without the need to being directly welded and fixed.When curb girder 1-1 and crossbeam 1-2 is directly welded and fixed, based on mounting structure and space constraint, the weld seam that welding is formed is difficult to range estimation, be not easy to welding and air-leakage test, and air chamber 1-3 position of weld is not blocked, weld seam is easy to observation, thus is easy to welding and air-leakage test.
