Description
Technical field
The utility model relates to a kind of steel-aluminium composite conducting rail of antivibration, belongs to the equipment of track traffic power supply usefulness.
Background technology
Before the utility model is made, in prior art, the steel-aluminium composite conducting rail that the 3rd rail electric power system of track traffic such as subway, light rail is adopted, for example application number is 03262580.4 steel-aluminium composite conducting rail, its steel combines with aluminium, relies on cold stamping aluminium to be clamp-oned in the stainless hole.Have the interference of vibratory force in steel-aluminium composite conducting rail uses, the creep slowly of long-term vibration back aluminium makes the tolerance clearance of aluminium in hole become big, and the tightening degree of steel and aluminium reduces, and contact resistance increases, and electric conductivity reduces.The steel-aluminium composite conducting rail length-diameter ratio is big, and the single order eigentone of this elongated body of rod is low, easily by the low-frequency vibration excitation resonance of travelled by vehicle rail.The zero dimension damping ratio of the compound rail of existing various steel aluminium when vibration is little, and the magnification factor during resonance is big.Can't adapt to the environment that the trailer vehicle speed improves the vibration aggravation that causes.
Technology contents
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of bigger damping ratio that has is provided, and is difficult for resonance, the steel-aluminium composite conducting rail that can keep steel aluminium to be adjacent under long-term vibration.
The main solution of the utility model is achieved in that the utility model mainly adopts and has the i section aluminium alloy section bar 1 that two side interior angles are 95 ° to 118 ° last convex 3, embeds two stainless steel tanks 2 that the side interior angle is bigger 2 ° to 5 ° than the interior angle of last convex 3; Two sides of stainless steel tank 2 longitudinally cut out sawtooth 4.Under the lateral forces of the compound special plane of steel aluminium, journal stirrup 5 translation to the inside and the rotation of aluminium alloy extrusions 1, the inside part aluminum alloy materials of journal stirrup 5 is clamp-oned in the sawtooth 4 of stainless steel tank 2, and force the interior angle of two sides of stainless steel tank 2 in elastic range, to reduce, make the angle between two inboards of two sides of last convex 3 of aluminium section bar 1 and stainless steel tank 2 be reduced to 0.5 ° to 3 ° by 2 ° to 5 °; And be coated with full Polymer viscoelastic damping material 6 in advance in the crack during this time.Journal stirrup 5 is tightly embraced stainless steel tank 2, and the last end face of last convex 3 and the inner bottom surface of stainless steel tank 2 are adjacent to, and aluminium section bar 1 forms one with stainless steel tank 2.
Compared with the prior art the utility model has the following advantages:
1, good anti-vibration.Because two sides of stainless steel tank 2 are in the certain elastic deformation scope, side certain angle that tilts again, journal stirrup 5 by aluminium section bar 1 is pushed down, so the vertical component of the elastic reactance of two sides of stainless steel tank 2 can increase the power that is adjacent to of steel aluminium faying face, have the opposing vibratory force and destroy the characteristics of steel aluminium in conjunction with firmness, contact resistance can not increase, and makes steel-aluminium composite conducting rail keep long-term conductive stability under the dynamic action of vibration that the traveling rail transmits and locomotive pantagraph current collector.Owing to filled up Polymer viscoelastic damping material 6 between the journal stirrup 5 of aluminium section bar 1 and two sides of stainless steel tank 2, make the zero dimension damping ratio C/Cc of steel-aluminium composite conducting rail when vibration by bringing up to C/Cc=0.4 less than 0.1, magnification factor when low-frequency resonance has effectively suppressed resonance by dropping to more than 10 times below 1.6 times.Lay the foundation for improving locomotive running speed.
2, steel and aluminium and three-dimensional anchoring strength height.The horizontal side of various steel-aluminium composite conducting rails is generally all higher to binding force, and difference is at vertical and vertical binding force.The root width of the journal stirrup 5 of aluminium section bar 1 is greater than existing various steel-aluminium composite conducting rails in the utility model, and two side interior angles of stainless steel tank 2 are bigger, make the vertical anchoring strength of steel aluminium of the present utility model that assurance arranged.Sawtooth 4 in the utility model on the stainless steel tank 2 hand hay cutter limits is used for strengthening steel aluminium longitudinal strength, through the compound special plane of steel aluminium to the hand hay cutter of the journal stirrup 5 of aluminium section bar 1 to extruding, be pressed into the calixconcavity place of sawtooth after the journal stirrup 5 inboard aluminium distortion, provide steel aluminium enough longitudinally shearing strength values, prevent that the inconsistent long-term circulation shear that causes of steel and aluminothermy coefficient of expansion from destroying, and can prevent vertical and bending horizontal direction.

The specific embodiment
Following the utility model in conjunction with the accompanying drawings 1 and the embodiment of accompanying drawing 2 be further described: the utility model mainly adopts stainless steel tank 2 to be embedded in the i section aluminium alloy section bar 1 and forms.The both sides interior angle of the last real platform 3 of aluminium alloy extrusions 1 is an a certain angle among 95 ° to 118 °, stainless steel tank 2 adopts the stainless steel band of number millimeters thick, its both sides stamp out the serration pit on punch press, become the channel-section steel of 97 ° to 123 ° at interior angle again through clod wash roll extrusion flanging, the interior angle of stainless steel tank 2 dual-sides is than a certain angle in big 2 ° to 5 ° of the both sides interior angle of the last convex 4 of aluminium alloy extrusions 1, after Polymer viscoelastic damping material 6 is coated in the journal stirrup 5 inboard grooves bottom of aluminium alloy extrusions 1, stainless steel tank 2 is buckled in the middle of the last convex 3 and journal stirrup 5 of aluminium alloy extrusions 1, send into together in the steel aluminium composite production line, last lower pressure wheel by main frame in the manufacturing line compresses steel and aluminium up and down, the left and right sides of main frame is exerted pressure while rotating to the pinch roller ecto-entad, journal stirrup 5 is that the center of circle turns to the inside with its root, also sliding deformation to the inside of the root of journal stirrup 5 subsequently, the inboard lower part of journal stirrup 5 have the part aluminum alloy materials to be entered the calixconcavity place of the sawtooth 4 of stainless steel tank 2 by cold-extruded.Journal stirrup 5 also further makes turn to the inside a certain angle in 0.5 ° to 3 ° of two sides of stainless steel tank 2, and the rotation of two sides of stainless steel tank 2 belongs to the scope of elastic deformation.Stainless like this steel tank 2 is just tightly embraced by journal stirrup 5, and the two strikes up partnership.Polymer viscoelastic damping material 6 is full of the last convex 3 of aluminium alloy extrusions 1 and the interior hand hay cutter of two sides of stainless steel tank 2, strengthened the zero dimension damping ratio of steel-aluminium composite conducting rail, the upper surface of the last convex 3 of the inner bottom surface of stainless steel tank 2 and aluminium alloy extrusions 1 tightly touch, and has guaranteed the conductivity performance between steel and the aluminium.
