Description
Technical field
The present invention relates to a kind of magnetic suspension to bear bearing, belongs to magnetic-levitation technical field of transportation.
Background technology
Magnetic suspension train change conventional rails vehicle lean on wheel track frictional force promote mode, using magnetic levitation car body,
Linear motor actuation techniques utilize the principle of " identical charges repel each other, and there is a natural attraction between the sexes ", allow car body to have and resist gravitational ability,
And track is completely disengaged, it is suspended in and is vacantly travelled apart from about 1 centimeters of track, create the strange of almost " zero elevation " space flight
Mark.The characteristics of magnetic suspension train is：The speed of service is fast, steady comfortable, it is easy to accomplish to automatically control；It is noiseless, however not excluded that harmful
Exhaust gas is conducive to environmental protection.
But due to being suspended in when train driving above track, centrifugal force and water when earthquake when wind-engaging obstructs dynamic, turning
The influence of the factors such as straight snips power is mounted under these special operation conditions and weather condition between magnetic suspension rail and bridge pier
Magnetic suspension beam support just must the transmission of bearing track beam body tensile, compressive, bending, the load such as cut, turn round, and be reliably delivered under bearing
Portion's bridge pier.The effect that magnetic suspension beam support is carried and transmitted is better, and stability, safety and service life are higher.
Invention content
The goal of the invention of the present invention is：In view of the above problems, a kind of magnetic suspension is provided and bears bearing, structure letter
It is single, the tensile, compressive, bending of beam body transmission can be born under special operation condition, cut, the load such as torsion and are reliably transferred the load to lower part
Structure, and each component mostly uses the mode of sliding friction pair and pivoting friction secondary combination, reduces the excessive wear between mating parts.
The technical solution adopted by the present invention is such：
A kind of magnetic suspension bears bearing, including upper anchoring unit, upper pre-embedded steel slab, tension compression bearing top plate, pulling plug, rebound, pressure
Block bears base-plate, lower pre-embedded steel slab and lower anchoring unit, and several upper anchoring units are set at the top of the upper pre-embedded steel slab, and
It is connect by anchor bolt with tension compression bearing top plate below, the pulling plug passes through rebound upper surface convex spherical from the bottom up
The two is flexibly connected by the through-hole of structure centre and the threaded hole of tension compression bearing top plate lower part concave spherical surface structure centre, the transition
For plate by two side pressing blocks and bolt presses on bearing base-plate, the lower pre-embedded steel slab bears bearing bottom with above it
Plate is connected by anchor bolt, and its bottom sets several lower anchoring units.
Above-mentioned technical proposal has the beneficial effect that：
1, flexible connection is realized in the top and the bottom of bearing by pulling plug and rebound, has rotating function, can be under special operation condition
The tensile, compressive, bending of beam body transmission are born, cuts, the load such as torsion and load be reliably transmitted to substructure from superstructure；
2, be the revolute pair of mating spherical surfaces form between tension compression bearing top plate and rebound, have it is each to rotating function, and can
The vertical load that tension compression bearing top plate is born largely is transmitted downwards；
3, the connection type of each movable part is face contact, when by greater impact or loading force, load and abrasion
Amount is better than the line contact of the prior art, therefore has the characteristics that good supporting effect, supporting ＆ stablizing, reliability be not high, easy to wear.
Preferably, through-hole on the rebound is up-small and down-big ladder hole, pulling plug lower end head it is upper
It is equipped between the cascaded surface of the ladder hole of surface and rebound and bears liner plate.Further preferably, on the head of the pulling plug lower end
Surface is convex spherical structure, and the liner plate outer surface that bears is cylindrical shape, and inner surface is to be matched with the convex spherical on pulling plug head
Concave spherical surface structure and concave spherical surface structure centre be useful for the through-hole that pulling plug passes through.Mating spherical surfaces are formed between pulling plug and rebound
The revolute pair of form, has each to rotating function, can bear the drawing of beam body transmission, cut, the load such as torsion.
Preferably, tension compression bearing top plate lower part concave spherical surface is equipped with annular groove and to inlay macromolecule in slot resistance to
Grind material.Preferably, sliding friction pair is arranged between the rebound and briquetting.Preferably, on the rebound bottom surface
High molecular abrasion-proof material is inlayed equipped with annular groove and in slot, with the mirror face stainless steel board group for bearing the welding of base-plate upper surface
It is secondary at friction.It is respectively equipped with sliding pair between rebound and briquetting and tension compression bearing bottom plate, there is sliding function.Throughout it is arranged
Wear-resistant material, sliding friction pair can effectively prolong the service life.
Preferably, the anchor hole passed through for anchor bolt on the tension compression bearing top plate, which is longitudinal strip-shaped hole, makes bearing
Has the function of fine tuning to installation along bridge, the anchor hole passed through for anchor bolt on base-plate that bears is Cross slat
Shape hole makes bearing have the function of fine tuning in direction across bridge installation, to ensure bearing.
