Description
Technical field
The present invention relates to track traffic, more particularly to a kind of medium-and low-speed maglev track switch vibration suppression type main beam structure.
Background technology
Medium-and low-speed maglev track traffic has safe for operation, pollution-free, low cost as a kind of new orbital fashion
Advantage.Had broad application prospects in Urban Rail Transit Development.
Medium-and low-speed maglev train is using the rail method of operation is embraced, by suspension controller control installation and train suspension rack
Electromagnet adsorbs F rails, the magnetic-levitation train is in suspended state.Train is driven to orbit by linear electric motors.It is but real
It is absolute rigidity and totally straight that magnetic levitation track, which is not, on the circuit of border.Therefore suspension controller need to be adjusted by controlling in real time
Controling power so that train can be suspended in fixed height in orbit, but the continuous adjustment of controling power can cause track structure
Vibration.But it is complicated under rail in practice, there are bridge, roadbed to also have track switch etc..Structure can show track under different rails
Go out different vibration characteristics.Thus need to carry out vibration research respectively for different structural vibrations such as track, bridge, track switches, from
Multiple angles such as suspension controller, structure optimization and structural vibration reduction find the measure of low Criterion for Maglev Guideway Structures vibration in solution.
Because medium-and low-speed maglev track switch uses steel beam structure, relative to interval orbit beam, its small, natural frequency of structures of deadweight
It is low, structural damping is low, therefore when suspend control adaptability it is not strong enough when, vehicle by Cha Qu and easily occur car branch off coupling shake
It is dynamic.Therefore for raising vehicle smoothness, it is necessary to suppress to car trouble coupled vibrations.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of medium-and low-speed maglev track switch girder vibration suppression construction, effectively to suppress
Car trouble coupled vibrations, improves vehicle smoothness.
The technical proposal for solving the technical problem of the invention is as follows：
A kind of medium-and low-speed maglev track switch girder vibration suppression construction of the present invention, is included in what is swung between positive position, lateral position
The main girder steel of track switch, it is characterized in that：The bottom of the main girder steel of track switch is installed with spring damping component, in its positive position, side
The anchoring device that fixed setting is driven by motor on to the pedestal below position, anchoring device act on spring damping component,
It is set to be changed between being tightened up and resetting two states.
The invention has the advantages that the grappling rigidity by improving track switch, increase grappling damping, improve its natural frequency of vibration
And energy dissipation capacity, fundamentally solve medium-and low-speed maglev vehicle track switch Coupled vibration problem, improve track switch stress, improve vehicle fortune
Row stationarity.

Embodiment
The present invention is further described with example below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, a kind of medium-and low-speed maglev track switch girder vibration suppression of the invention construction, is included in positive position A, side
To the main girder steel 1 of track switch swung between the B of position.The bottom of the main girder steel 1 of track switch is installed with spring damping component 2, at it
The anchoring device 3 driven by motor 4 is fixedly installed on pedestal below positive position A, lateral position B, anchoring device 3 acts on
Spring damping component 2, it is set to be changed between being tightened up and resetting two states.
Because medium-and low-speed maglev track switch uses steel beam structure, relative to interval orbit beam, its small, natural frequency of structures of deadweight
It is low, structural damping is small, therefore when suspend control adaptability it is not strong enough when, vehicle by Cha Qu and easily occur car branch off coupling shake
It is dynamic.Train rail coupled vibration is but conversely not susceptible in bridge section and roadbed section, this is due in bridge and roadbed section rail
The lower rigidity of structure is big, the natural frequency of vibration is high and foundation anchor ability is strong.The most effectual way for thus solving car trouble coupled vibrations is to carry
The anchoring strength of high track switch, its natural frequency of vibration and energy dissipation capacity are improved, fundamentally suppress track switch vibration.
Referring to Figures 1 and 2, during the main turn-out track of girder steel 1 of track switch, spring damping component 2 moves therewith.Work as track switch
The main turn-out track of girder steel 1 in place after, the anchoring device 3 that motor 4 drives acts, and acts on spring damping component 2, hinders spring
Buddhist nun's component 2 is tightened up generation pretightning force, by the main girder steel 1 of track switch together with pedestal grappling, so as to improve the intrinsic of track switch girder
Frequency and the main damping ratios that shake, suppress the vibration of track switch girder.
A kind of concrete structure of spring damping component 2 is shown in Fig. 2 and Fig. 4, i.e., described spring damping component 2 is by installing
Seat 21, spring-damper 22 and grappling wheel 23 are formed, and the upper end of spring-damper 22 is fixedly connected with mounting seat 21, mounting seat 21
It is fixedly connected with the main girder steel 1 of trouble, grappling wheel 23 is installed on the lower end of spring-damper 22.
Fig. 3 shows a kind of concrete structure of anchoring device 3, and anchoring device 3 includes anchor block 31, support base 32 and by ten
The screw-nut body that font nut 33, geared screw 34 are formed.The anchor block 31 and one end and support base 32 are be hinged, another
End is be hinged with cross nut 33, and its middle part then has the notch passed in and out for grappling wheel 23 and the lower end of spring-damper 22
36。
Reference picture 4, the top of the geared screw 34 coordinate with the transmission of cross nut 33, lower end and motor 4
The transmission of drive screw 35 coordinates.When the main turn-out track of girder steel 1 of track switch in place after, grappling wheel 23 and the lower end of spring-damper 22 enter card
In slot structure 36, motor 4 drives geared screw 34 to rotate forward through drive screw 35, and grappling is driven through cross nut 33
Seat 31 is deflected down, and grappling wheel 23 is acted on by notch 36, spring-damper 22 is stretched and is produced pretightning force, improves road
The intrinsic frequency of trouble girder and the main damping ratios that shake, suppress the vibration of track switch girder.It is first when the main girder steel 1 of track switch needs turn-out track
First drive geared screw 34 to reversely rotate by drive screw 35 by motor driving 4, grappling is driven through cross nut 33
Seat 31 upward deflects, and releases the locking to grappling wheel 23 and is at free state, track switch can free turn-out track.
A kind of some principles of medium-and low-speed maglev track switch girder vibration suppression construction of the present invention that simply explains through diagrams described above,
It is not intended to by the present invention in shown and described concrete structure and the scope of application, therefore every corresponding modification that may be utilized
And equivalent belongs to apllied the scope of the claims of the present invention.
