Abstract
The utility model relates to a cork rubber pad placed under rails, which is used for concrete sleepers. The utility model is characterized in that the pad is a rectangular parallelepiped rail pad with flat surfaces; cork grains are uniformly distributed in the rubber; the weight specifications of the pad are light, mid-heavy and heavy. The utility model has the characteristics of strong compression resistance, excellent rebound performance, small deformation, large vertical stiffness, aging resistance, etc. Besides, the speed of a train and the effects of vibration isolation and safety can be enhanced; the cost can be reduced, and the maintenance and repair cost can be reduced. The utility model has significance in promoting the development of railway construction in China.
Description
The utility model relates to the fixedly rail bar on the sleeper, pad or similar item, the rubber pad class under the rail chair, specifically a kind of cork-rubber pad that is used for concrete crosstie.
The China railways sleeper has been used instead since the concrete crosstie, all adopt the gum pad, because often lateral spread behind the generation pressurized, sleeper is more fragile, and resilience is little, and permanent deformation is big, not ageing-resistant, so application life is short, has increased railway construction investment and repair and replacement expense, influences high-speed, the high-quality development of railway construction in China.
The utility model provides a kind of cork compressibility that both had for avoiding above-mentioned weak point of the prior art, and the high resiliency of rubber is arranged again, and energy vibration isolation sound-absorbing, ageing-resistant cork-rubber composite material sleeper pad.
The purpose of this utility model can reach by following measure:
Cork-rubber sleeper pad is certain thickness for having, the rectangular pad that appearance is smooth, and the granulated cork in the bolster is evenly distributed in the rubber, and its specification can have following three kinds: light-duty: 184 * 114 * 10 millimeters; Medium-sized: 184 * 120 * 10 millimeters; Heavy: 184 * 132 * 10 millimeters.The manufacturing of cushion prescription mainly by rubber, stearic acid, zinc oxide, sulphur, the last of the ten Heavenly stems dibutyl ester, pure granulated cork form.
Description of drawings is as follows:
Accompanying drawing is a cork-rubber sleeper mat structure schematic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
The China railways sleeper has been used instead since the concrete sleeper, continues to use the gum backing plate always, and result of use is bad, and maintenance cost increases.The utility model bolster 1 specification as shown in drawings is 184 * 132 * 10 millimeters a heavy cork-rubber sleeper pad.Its manufacturing process is to use following raw materials by weight percent: rubber 3000 grams are plasticated with rubber mixing machine, add stearic acid 30 grams more successively, zinc oxide 150 grams, sulphur 60 grams, accelerator 7.5 grams, carbon black 1200 gram, the last of the ten Heavenly stems dibutyl ester 600 grams, antioxidant D 30 grams, antioxidant 4010,30 grams, mixing cork powder 3600 grams that evenly add again, the even back of refining slice, specification by 184 * 132 * 10 millimeters is cut into blank, airing is packed in the mould, sends in the vulcanizing press under 155 ℃ and 80 kilograms of pressure, vulcanizes through 50 minutes, take out the demoulding, produce 22 cork-rubber bolsters.
The utility model compared with prior art has following advantage:
1, surfacing, no groove have no chance rib, no rubber veneer, and inside and outside material is evenly distributed.
2, the utility model compressibility and resilience are good, and transversely deforming is little, and vertical stiffness is little, energy vibration isolation, sound-absorbing, ageing-resistant, long service life.
3, cork-rubber sleeper pad is easy to make, and is with low cost, extensively promotes quickening railway construction in China career development meaning very grave.
