Abstract
The invention discloses a damping and noise reducing structure in train traveling. The structure is formed by a component 1, a T-shaped steel rail, a component 2, an inclined inner side face wheel, a component 3, a single cambered surface cushion block, a component 4 and a damping block; wherein the single cambered surface cushion block is arranged on the damping block; the T-shaped steel rail is arranged on the single cambered surface cushion block; and the inclined inner side face wheel is placed on the T-shaped steel rail. The damping and noise reducing structure in train traveling has the beneficial effects that 1, the vibration nose generated in train traveling can be effectively reduced; and 2, the service life of a concrete bearing structure can be effectively prolonged.
Description
Technical field
The present invention relates to a kind of damping and fall noise structure, noise structure falls in the damping related in particular in a kind of train driving
Background technology
Current train all can send very large vibrations and noisiness under steam, not only vibrations are produced to compartment, and the environment of rail periphery is also had an impact, even certain destruction is also produced to the concrete bearing structure under rail, thus greatly shorten the application life of concrete bearing structure.
Summary of the invention
The present invention by 1, T steel rail, 2, oblique medial surface wheel, 3, single cambered surface cushion block, 4, snubber block form, it is characterized in that on shock resistance block, be placed with single cambered surface cushion block, single cambered surface cushion block be equipped with T steel rail, T steel rail is put oblique medial surface wheel.
The cross section entirety of T steel rail is I-shaped, and upper end, cross section is T-shaped.
Oblique medial surface wheel respectively has above a plectane is fastened on the cross section at the nearly two ends of cylinder, plectane planar central and cylinder section central point left and right directions coincide, the straight line be linked to be between plectane plane and cylinder section central point is at a right angle up and down, on the periphery of two blocks of plectanes nearly medial surface position on have one have bossy body protrude formed nearly right angle type recess, recess interior angle angle is slightly larger than right angle, and the outer disk of two blocks of plectanes forms straight line from left to right.
The entirety of single cambered surface cushion block is square, and one side is plane, being circular arc, on the position at the right and left proximal edge place, respectively having a hole to wearing before and after another side.
The entirety of snubber block is square, on position, plane the right and left antermarginal place, respectively has a hole to wearing.
Beneficial effect
Can compare and effectively reduce train vibrations noise sound under steam, thus effectively can extend the application life of concrete foundation.

Detailed description of the invention
Set level after bossy body 7 plane of concrete foundation 8 the right and left first sets up two set bolts 9 aimed in bossy body 7 plane of concrete foundation 8 the right and left of the holes in snubber block 6 plane, and then the arc surface of single cambered surface cushion block 5 upwards, set level after two set bolts 9 that in bossy body 7 plane that holes on arc surface aims at concrete foundation 8 the right and left respectively, snubber block 6 is outstanding above set up, after this in the position in the middle of two set bolts 9 also on the arc surface of single cambered surface cushion block 5, the lower plane of T steel rail 2 is put in downwards, last on the both sides tapered plane of the lower end of T steel rail 2 the upper plane of rail pressing plate 4 upwards, set bolt 9 is aimed in middle hole, upper cap nut 3 is overlapped again after the proximal edge place that projection below aims at single cambered surface cushion block 5 sets up, treat the position between two T steel rails 2, Distance geometry height is determined and aligns good rear tightening nuts 3 formally to fix.
Pad be according to two T steel rails 2 between height whether need to determine whether to use, during use, two breach of the edge in its plane are aimed at respectively the front and back sides of set bolt 9, in the space under the lower plane of single cambered surface cushion block 5 and in the upper plane of snubber block 6, insert location.
When train runs on two T steel rails, the present invention can play following effect; Snubber block 6 alleviates and relaxes train impact force produced under steam to the powerful impact of concrete foundation 8 and vibrations at wheel through out-of-date can playing to a large extent.Snubber block 6 can play direct noise reduction at wheel to a large extent through out-of-date and cut off the propagation of impulsive sound in concrete foundation 8, concrete foundation 8 discord impulsive sound is as much as possible empathized, thus greatly alleviate the generation of noisiness, what single cambered surface cushion block 5 in use can effectively be avoided going out because of proximal edge before and after bossy body 7 plane in concrete foundation 8 plane is uneven, and the T steel rail 2 produced is in the imbalance of the actual negative gravity being uneven caused of convex massif plane rear and front end, thus greatly reduce train vibrations degree under steam and noisiness decibel.The lateral surface adopting T steel rail 2 and oblique medial surface wheel 1 can make full use of T steel rail 2 upper end and oblique medial surface wheel 1 excess area when contacting not contact action feature thus eliminate unnecessary side friction, and reduce the generation of noisiness greatly.Adopt T steel rail 2 and oblique medial surface wheel 1 can make full use of contact area large as far as possible on the plane of T steel rail 2 upper end and the periphery of oblique medial surface wheel 1, increase front frictional force, to reduce train oblique medial surface wheel and T steel rail 2 skidding on both faces when climbing and when braking.When tiltedly medial surface wheel 1 can allow train switch tracks under steam simultaneously, enable very level and smooth the removing from original orbital plane of the peripheral disc of oblique medial surface wheel 1, drive to another root T steel rail 2 to get on, and the phenomenon of slightly climbing that interior circular concave wheel occurs when switching tracks can not be produced, thus jolting and noisy phenomenon of fundamentally can eliminating that train occurs when switching tracks.
