Description

The three-dimensional adjustable pinch plate rail fastening of medium-and low-speed maglev system
Technical field
The utility model relates to magnetic levitation track technical field, is specially the three-dimensional adjustable pinch plate rail fastening of a kind of medium-and low-speed maglev system.
Background technology
Fastener system is the vitals of medium-and low-speed maglev track structure, the section of track is firmly connected with track by it, guarantee track stability, reliability are played an important role, in addition the elasticity of medium-and low-speed maglev track depends on fastener system substantially, and the precision of medium-and low-speed maglev track also will adjust by fastener system and keep.Therefore, the importance of fastener in medium-and low-speed maglev traffic route and apparent on the impact of transportation safety.
Current domestic magnetic float test wire and commercial line according to different sleeper type of design multiple medium-and low-speed maglev fastener, mainly contain elasticity regardless of open type and elasticity split two kinds.Its Elastic nonseparated rail fastening is generally directly resilient sleeper-bearing and height adjusting cushion plate are directly fixed on infrastructure by anchor bolt, only can realize longitudinal extension and vertically heighten, and cannot complete the transverse direction adjustment of section of track entirety.Section of track structure is connected with infrastructure by two groups of bolts by elasticity separated rail fastening, the three-dimensional adjustment of section of track structure can be realized, but all there is complex structure in existing elasticity separated rail fastening, crosswise joint scarce capacity, the feature that fastener part replacement is difficult in maintenance.
Utility model content
Therefore, in order to overcome the deficiency that prior art exists, the utility model provides one can realize three-dimensional regulation function, and elasticity is reasonable, the three-dimensional adjustable pinch plate rail fastening of medium-and low-speed maglev system easy to maintenance.
For solving the problems of the technologies described above, the utility model medium-and low-speed maglev system pinch plate rail fastening comprises H type sleeper, iron chair and the track arranged successively from top to bottom, also comprise buckle, H type sleeper is pushed down in one end of described buckle, and the other end of described buckle is arranged on iron chair by clamp nut through anchor bolt.
The beneficial effects of the utility model are as follows: 1, by using buckle to replace connecting bolt to realize fastener withholding the section of track, and arranging the resilient sleeper-bearing mated with buckle structure size on top, ensure that the elasticity of fastener system.
2, the amount of parts of fastener system can be reduced significantly while ensure the strength of clamping and roll adjustment performance, improve the reliability of fastener system.
3, by means of only horizontal roll adjustment block can complete to the section of track in length and breadth to adjustment and lateral locking to the section of track, achieve the three-dimensional adjustment of the section of track.
3, can reduce sleeper perforate and machining amount, reduce manufacturing cost, and the roll adjustment of fastener system and part replacement convenient and swift.
4, the utility model structure is simple, processing cost is low, easy for installation, for ease of maintenaince.
After reading the detailed description of the utility model embodiment by reference to the accompanying drawings, other features of the present utility model and advantage will become clearly.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention of the present utility model, the utility model medium-and low-speed maglev system pinch plate rail fastening is made the following instructions.
Embodiment: the three-dimensional adjustable pinch plate rail fastening of a kind of medium-and low-speed maglev system, comprise H type sleeper 12, iron chair 9 and the track 13 arranged successively from top to bottom, also comprise buckle 5, H type sleeper 12 is pushed down in one end of described buckle 5, and the other end of described buckle 5 is arranged on iron chair 9 by clamp nut 2 through anchor bolt 1.Resilient sleeper-bearing 10 and height adjusting cushion plate 11 is disposed with from top to bottom between the bottom of described H profile steel pillow 12 and the upper surface of iron chair 9.Horizontal roll adjustment block pad 8 and horizontal roll adjustment block 7 is provided with between the bottom of described buckle 5 and iron chair 9.This fastener also comprises damping pad 6, one end of described damping pad 6 is between buckle 5 and H type sleeper 12, the other end of described damping pad 6, between buckle 5 and horizontal roll adjustment block 7, has between the fluting of horizontal roll adjustment block 7 and H type sleeper 12 with the longitudinal adjustment amount of control to the gap adapted to.
During assembling, first height adjusting cushion plate 11 and resilient sleeper-bearing 10 are once stacked and align, horizontal roll adjustment block pad 8 and horizontal roll adjustment block 7 are stacked after aligning, through anchor bolt 1, above-mentioned parts is placed on iron chair 9, and complete anchor bolt 1 Height Adjustment by clamp nut 2, after the fluting finally fastener connected and H profile steel being rested the head on 12 aligns, successively damping pad 6 and buckle 5 are installed, finally tighten anchor bolt 1 according to design torque, complete the connection of fastener system and the section of track, behind the locus of the good section of track to be adjusted, concreting track 13, realize being connected and fixed of the section of track and infrastructure.Vertically to heighten, realize the difference amount of heightening by the height adjusting cushion plate 11 changing different-thickness.Longitudinally adjustment, H profile steel rests the head on the groove that 12 base plates have certain depth, and there is the spacing of 6mm in the face, bosom that during installation, horizontal roll adjustment block 7 and H profile steel rest the head ons the fluting of 12, under the effect of fastener longitudinal resistance, freely diffuses stress, the adjustment amount of realization-6-+6mm.Laterally adjustment, changes the horizontal roll adjustment block 7 of different eccentric throw, and bottom is by resilient sleeper-bearing 10, and top, by damping pad 6, completes two-way vibration damping.The clamp nut 2 of anchor bolt 1 is loosened when heightening, buckle 5, damping pad 6 and horizontal roll adjustment block 7 are taken out, extract height adjusting cushion plate 11 out, change the height adjusting cushion plate 11 of required adjustment amount, again horizontal roll adjustment block 7 is inserted, tighten clamp nut 2 according to preset torque, during its part replacement, only need to loosen clamp nut 2 and all conveniently can take out replacing.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
