Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
With reference to Fig. 2, medium-and low-speed maglev system track F rail joint design of the present invention, comprise its two ends respectively F rail 10 link main with a section form the secondary F rail 20 be connected.With reference to Fig. 3 and Fig. 4, the described main top of F rail 10 link outside between leg 101 and interior leg 102 arranges the boss 11 sunk relative to end face, and longitudinal front end of this connection boss 11 has the main limit buckle 12 crossed out.With reference to Fig. 3 and Fig. 5, outside described secondary F rail 20, the bottom surface at longitudinal two ends is provided with the cavity 22 corresponding with connecting boss 11, the outer end of cavity 22 has the secondary limit buckle 23 laterally inside contracted, and on the roof of cavity 22, lateral separation offers the elongated hole groove 21 of two longitudinal extensions.With reference to Fig. 3, the bolt being set with floor clip makes the formation of F rail 10, secondary F rail 20 removably connect in these two elongated hole grooves 21, arranges in the both sides connecting boss 11 resilient return member 30 that its two ends act on main limit buckle 12, secondary limit buckle 23 respectively.
With reference to Fig. 4, connect on boss 11 and be provided with two positions screwed hole corresponding with two elongated hole grooves 21, these two screwed holes try one's best layout in connection boss 11 both sides, and spacing strengthens with the torsional rigidity strengthening secondary F rail 20.The 2 main limit buckles 12 in place that on main F rail, horizontal direction is arranged, the headroom of main F rail 10 can be made full use of on the one hand, and do not affect the functional requirement of suspend control to the outer leg 101 of F rail, interior leg 102, the reliability that two sections of main F rails 10 longitudinally connect can also be strengthened on the other hand.This boss and F rail, still in one, ensure that the integrality of the rail level of the required detection of levitation gap sensor.With reference to Fig. 4, devise escape at main limit buckle 12 root, increase elastic reset member 30 with main limit buckle 12 in the contact area of longitudinal direction, also reduce the difficulty of processing of main limit buckle 12 simultaneously.For avoiding stress to concentrate, and protecting operating personnel's safety, connecting boss 11 root and protuberance correspondingly designs corners and fillets at main F rail 10.
With reference to Fig. 3 and Fig. 5, secondary limit buckle 23 on secondary F rail 20, mainly coordinates with the main limit buckle 12 of the limit of main F rail 10, and is laterally leaving certain gap, realize reliable longitudinal spacing between main F rail 10, secondary F rail 20 on the one hand, limit longitudinal extension amount excessive on main F rail 10; Meet the rotation demand between the main F rail 10 of accommodation curve section connection, secondary F rail 20 on the other hand.The compressible amount of resilient return member 30 at least should reach the pre-allowance of rail gap of joint, elastic reset member component 30 both can absorb the longitudinal extension energy of main F rail 10, secondary F rail 20, the longitudinal centering of secondary F rail 20 can also be realized, avoid the overall offset phenomenon that secondary F rail 20 causes because joint, two ends screw in compression power is different with contact surface frictional force.The determination of secondary F rail 20 longitudinal length, in conjunction with medium-and low-speed maglev system suspension controller control strategy and requirement, should also need binding curve orbital characteristics (sweep etc.) and joint geographic layout information.
With reference to Fig. 5, the top of described cavity 22 the inner offers rail gap through hole 24.The setting of rail gap through hole 24 is not mainly in order to affect the Data Source of levitation gap sensor, namely when levitation gap sensor is by joint, its test surface situation can only have two kinds, a kind of is the soffit (reflection actual real levitation gap) of main F rail 10, another kind is cannot the through hole of feedback signal, thus ensure that the unicity of sensor signal, be convenient to the design of suspension controller.Also devise escape at secondary F rail 20 secondary limit buckle 23 root, increase the contact area of resilient return member 30 end face and secondary limit buckle 23 as far as possible.And also devise corresponding corners and fillets in positions such as the root of secondary F rail 10 cavity 22 and protuberances, to avoid stress to concentrate, meet joint design practicality.The setting of main F rail 10, secondary F rail 20 protuberance chamfering, is also beneficial to secondary F rail when using on curve track, strengthens the deflection angle between major-minor F rail.
With reference to Fig. 3 and Fig. 5, described main F rail 10 link is fixedly installed the contiguous block 13 longitudinally stretched out in wing rail 103 bottom surface, this contiguous block 13 offers the elongated hole groove 131 of longitudinal extension, the bolt being set with floor clip makes the formation of main F rail 10, secondary F rail 20 removably connect in this elongated hole groove 131, thus increase the overall torsional rigidity of secondary F rail 20, and control joint smooth degree better.
With reference to Fig. 6, the present invention may be used for the connection of curve track section.On curve track, define angle α between secondary F rail 20 center line and main F rail 10 center line, angular dimension can regulate etc. according to line feature (sweep, joint geographic layout information).
The present invention, on the layout type of F rail wing rail place rail gap, devises two kinds of seam arrangements, and all more existing parallel arrangement mode has had very large change.
With reference to Fig. 7, the first joint layout's mode adopts right angle rail gap transition structure, namely described wing rail 103 longitudinal terminal surface and corresponding secondary F rail 20 inner side end are the right-angle folding face of matching, when support wheel scrolls through this rail gap along the longitudinal direction at design attitude (suspension rack does not produce the situation of lateral shift), first main F rail 10 and half roller contact, and bear its rolling and move ahead; Treat that wheel rolls across rail gap, namely can bear second half wheel by secondary F rail 20 to move ahead, thus when making support wheel cross rail gap, the impingement area of support wheel only has half support wheel width, alleviate the situation of the contact surface sudden change that support wheel faces at rail gap place, the impact shock that support wheel bears can be reduced.The transverse movement amount allowed when suspension rack is less than support wheel width one half, and the mentality of designing of this rail gap transition structure is all effective, and only the support wheel area that bears of two sections of right angle changeover portions is different, is also to alleviate the impact that existing parallel seams causes.
With reference to Fig. 2, described wing rail 103 longitudinal terminal surface and corresponding secondary F rail 20 inner side end are the face, oblique angle of matching.When support wheel scrolls through this rail gap, the change of wing rail 103 contact plane of support wheel and main F rail 10 is gradual changes, increase gradually, support wheel contact surface can be reduced largely and to suddenly change the impact shock caused, effectively reduce vibration when support wheel crosses rail gap.When there is transverse movement bigger than normal for vehicle suspension frame entirety, the gradual effect of the contact surface of this transition structure to emergent support wheel is still effective.
Some principles of the above medium-and low-speed maglev system track F rail joint design of the present invention that just explains through diagrams, be not the present invention to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the present invention applies for.
