Abstract
A medium-and-low-speed maglev turnout girder vibration suppression structure effectively suppresses turnout coupling vibration and improves train operation stability. The structure comprises a main steel turnout girder swinging between a forward position and a lateral position. A spring damping component is fixedly installed at the bottom of the main steel turnout girder. An anchoring device driven by a drive motor is fixedly arranged on a base below the forward position and the lateral position of the vibration suppression structure. The anchoring device acts on the spring damping component so that the spring damping component can be switched between a tensioned state and a reset state.

Technical field
The present invention relates to track traffic, press down vibration shape girder knot particularly to a kind of medium-and low-speed maglev track switch
Structure.
Background technology
Medium-and low-speed maglev track traffic, as a kind of novel orbital fashion, has operation safety, without dirty
Dye, the advantage that cost is low.Urban Rail Transit Development has broad application prospects.
Medium-and low-speed maglev train uses embraces the rail method of operation, controls to install and train by suspension controller
Electric magnet on suspension rack adsorbs F rail, makes magnetic-levitation train be in suspended state.Pass through straight-line electric
Machine drives train to orbit.But magnetic levitation track is not that absolute rigidity is with complete on actual track
Straight.Therefore suspension controller need to adjust control power by controlling in real time so that train can be
It is suspended in fixing height on track, but the continuous adjustment controlling power can cause track structure to vibrate.So
And structure is complicated under rail in reality, bridge, roadbed is had to also have track switch etc..Under different rails, structure can make
Track shows different vibration characteristics.So that for different structures such as track, bridge, track switches
Vibration carries out vibration research, respectively from multiple angles such as suspension controller, structure optimization and structural vibration reductions
Find the measure of low Criterion for Maglev Guideway Structures vibration in solving.
Owing to medium-and low-speed maglev track switch uses steel beam structure, relative to interval orbit beam, its deadweight is little,
Natural frequency of structures is low, structural damping is low, therefore when the control adaptation ability that suspends is strong not, and vehicle
By Cha Qu and easy generation car trouble coupled vibrations.Therefore for improving vehicle smoothness, need car
Trouble coupled vibrations suppresses.
Summary 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 and presses down the structure that shakes,
With effectively suppression car trouble coupled vibrations, improve vehicle smoothness.
It is as follows that the present invention solves the technical scheme that technical problem used:
A kind of medium-and low-speed maglev track switch girder of the present invention presses down the structure that shakes, and is included in forward position, lateral
The main girder steel of track switch swung between Wei, is characterized in that: the bottom of the main girder steel of described track switch is installed with
Spring damping component, the pedestal below its forward position, lateral position is fixedly installed by driving motor to drive
Dynamic anchoring device, anchoring device acts on spring damping component so that it is is being tightened up and is resetting two kinds
Change between state.
The invention has the beneficial effects as follows, by improving the grappling rigidity of 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 vibrations
Problem, improves track switch stress, improves vehicle smoothness.

Detailed description of the invention
The present invention is further described with example below in conjunction with the accompanying drawings.
Seeing figures.1.and.2, a kind of medium-and low-speed maglev track switch girder of the present invention presses down the structure that shakes, including
The main girder steel of track switch 1 swung between forward position A, lateral position B.The end of the main girder steel of described track switch 1
Portion is installed with spring damping component 2, solid on the pedestal below its forward position A, lateral position B
Fixed setting is by the anchoring device 3 driving motor 4 to drive, and anchoring device 3 acts on spring damping component
2 so that it is change between two states being tightened up and resetting.
Owing to medium-and low-speed maglev track switch uses steel beam structure, relative to interval orbit beam, its deadweight is little,
Natural frequency of structures is low, structural damping is little, therefore when the control adaptation ability that suspends is strong not, and vehicle
By Cha Qu and easy generation car trouble coupled vibrations.But it is not susceptible in bridge interval and roadbed interval on the contrary
Train rail coupled vibration, this be owing under bridge and roadbed interval rail, the rigidity of structure is big, the natural frequency of vibration is high,
And foundation anchor ability is strong.Thus the most effectual way solving car trouble coupled vibrations is to improve track switch
Anchoring strength, improves its natural frequency of vibration and energy dissipation capacity, the fundamentally vibration of suppression track switch.
Seeing figures.1.and.2, during track switch main girder steel 1 turn-out track, spring damping component 2 is with it
Move together.After track switch main girder steel 1 turn-out track puts in place, drive the anchoring device 3 that motor 4 drives
Action, and act on spring damping component 2, make spring damping component 2 be tightened up generation pretightning force,
Together with main for track switch girder steel 1 is anchored on pedestal, thus improves the natural frequency of track switch girder and main shake
Damping ratios, suppression track switch girder vibration.
Showing a kind of concrete structure of spring damping component 2 in Fig. 2 and Fig. 4, the most described spring hinders
Buddhist nun's component 2 is taken turns 23 by mounting seat 21, spring-damper 22 and grappling and is constituted, spring-damper 22
Upper end and mounting seat 21 fixing is connected, mounting seat 21 girder steel main with trouble 1 is fixed and is connected, grappling wheel
23 lower ends being installed on spring-damper 22.
Fig. 3 shows a kind of concrete structure of anchoring device 3, anchoring device 3 include anchor block 31,
Support seat 32 and be made up of and screw-nut body cross nut 33, geared screw 34.Described
Anchor block 31 and one end are hinged with support seat 32, and the other end is hinged, wherein with cross nut 33
Portion then has for grappling wheel 23 and the notch 36 of spring-damper 22 lower end turnover.
With reference to Fig. 4, the top of described geared screw 34 coordinates with nut transmission, lower end and driving electricity
Driving screw rod 35 transmission of machine 4 coordinates.After track switch main girder steel 1 turn-out track puts in place, grappling wheel 23
Enter in notch 36 with spring-damper 22 lower end, drive motor 4 through driving screw rod 35
Driven gear screw rod 34 rotates forward, and drives anchor block 31 to deflect down through cross nut 33,
Acted on grappling wheel 23 by notch 36, make spring-damper 22 be stretched generation pretightning force,
Improve the natural frequency of track switch girder and the main damping ratios that shakes, suppression track switch girder vibration.Work as track switch
When main girder steel 1 needs turn-out track, first by driving motor to drive 4 by driving screw rod 35 driven gear
Screw rod 34 reversely rotates, and drives anchor block 31 to upward deflect through cross nut 33, releases anchor
The locking of fixed wheel 23 is at free state, and track switch can free turn-out track.
The above one medium-and low-speed maglev track switch girder of the present invention that simply explains through diagrams presses down the structure that shakes
Some principles, be not intended to by the present invention in shown and described concrete structure and the scope of application,
Therefore every corresponding amendment that may be utilized and equivalent belong to the apllied patent of the present invention
