Description
Technical field
This utility model is related 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 is as a kind of new orbital fashion, safe and pollution-free, low cost with running
Advantage.Have broad application prospects in Urban Rail Transit Development.
Medium-and low-speed maglev train is controlled in installation and train suspension rack by suspension controller using the rail method of operation is embraced
Electric magnet makes magnetic-levitation train be in suspended state adsorbing F rails.Train is driven to orbit by linear electric motors.But it is real
On the circuit of border, magnetic levitation track is not absolute rigidity and totally straight.Therefore suspension controller need to be adjusted by real-time control
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 complex structure under rail in practice, there are bridge, roadbed to also have track switch etc..Under different rails, structure shows can track
Go out different vibration characteristics.So that carry out vibration research respectively for the different structural vibration such as track, bridge, track switch, 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 solving.
As medium-and low-speed maglev track switch adopts steel beam structure, relative to interval orbit beam, its little, natural frequency of structures of deadweight
Low, structural damping is low, and therefore when suspension control adaptability is not strong enough, vehicle occurs car trouble coupling and shakes by Cha Qu and easily
Dynamic.Therefore for improving vehicle smoothness, need to suppress car trouble coupled vibrations.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of medium-and low-speed maglev track switch girder vibration suppression construction, with effective
Suppress car trouble coupled vibrations, improve vehicle smoothness.
The technical scheme adopted by this utility model solution technical problem is as follows:
A kind of medium-and low-speed maglev track switch girder vibration suppression construction of the present utility model, is included between positive position, lateral position and puts
The main girder steel of dynamic track switch, is characterized in that:The bottom of the main girder steel of the track switch is installed with spring damping component, positive at which
It is fixedly installed, on pedestal below position, lateral position, the anchoring device driven by motor, anchoring device acts on spring damping
Component so as to change and reset two states between being tightened up.
The beneficial effects of the utility model are, by improving the grappling rigidity of track switch, increase grappling damping, improve its self-vibration
Frequency and energy dissipation capacity, fundamentally solve medium-and low-speed maglev vehicle track switch Coupled vibration problem, improve track switch stress, improve car
Running stability.

Specific embodiment
This utility model is further illustrated with example below in conjunction with the accompanying drawings.
See figures.1.and.2, a kind of medium-and low-speed maglev track switch girder vibration suppression construction of the present utility model is included in positive position
The main girder steel 1 of the track switch of swing between A, lateral position B.The bottom of the main girder steel 1 of the track switch is installed with spring damping component 2,
The anchoring device 3 driven by motor 4 is fixedly installed on the pedestal below its positive position A, lateral position B, and anchoring device 3 is made
For spring damping component 2 so as to change and reset two states between being tightened up.
As medium-and low-speed maglev track switch adopts steel beam structure, relative to interval orbit beam, its little, natural frequency of structures of deadweight
Low, structural damping is little, and therefore when suspension control adaptability is not strong enough, vehicle occurs car trouble coupling and shakes by Cha Qu and easily
Dynamic.But train rail coupled vibration is not susceptible on the contrary in bridge interval and roadbed interval, this is due in bridge and roadbed interval rail
The lower rigidity of structure is big, the natural frequency of vibration is high and foundation anchor ability is strong.Thus the most effectual way for solving car trouble coupled vibrations is to carry
The anchoring strength of high track switch, improves its natural frequency of vibration and energy dissipation capacity, fundamentally suppresses track switch vibration.
See figures.1.and.2, during main 1 turn-out track of girder steel of track switch, spring damping component 2 is moved therewith.Work as track switch
1 turn-out track of main girder steel in place after, 3 action of anchoring device that motor 4 drives and acts on spring damping component 2, hinders spring
Buddhist nun's component 2 is tightened up generation pretightning force, by main for track switch girder steel 1 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 constituted, 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 constituted.The anchor block 31 and one end are hinged with support base 32, another
End is hinged with cross nut 33, and then there is in the middle part of which notch passed in and out for grappling wheel 23 and 22 lower end of spring-damper
36.
With reference to Fig. 4, the top of the geared screw 34 is coordinated with nut transmission, the drive screw of lower end and motor 4
35 transmissions coordinate.When main 1 turn-out track of girder steel of track switch in place after, grappling wheel 23 and 22 lower end of spring-damper enter into notch 36
Interior, motor 4 drives geared screw 34 to rotate forward through drive screw 35, drives anchor block 31 downward through cross nut 33
Deflection, acts on grappling wheel 23 by notch 36, makes spring-damper 22 be stretched generation pretightning force, improves track switch girder
Natural frequency and the main damping ratios that shake, suppress the vibration of track switch girder.When the main girder steel 1 of track switch needs turn-out track, first by driving
Motor drive 4 drives geared screw 34 to reversely rotate by drive screw 35, drives anchor block 31 upwards through cross nut 33
Deflection, releases and is at free state to the locking of grappling wheel 23, and track switch can free turn-out track.
Some of a kind of medium-and low-speed maglev track switch girder vibration suppression construction of the above this utility model that simply explains through diagrams
