Abstract
The utility model discloses a kind of carbon fiber compound step, there is composite bed, described composite bed is by three-decker, ground floor comprises common unsaturated polyester SMC layer by epoxy wear-resisting SMC layer, third layer, be be composited by castor oil three-glycidyl ether layer between described ground floor and third layer, epoxy resin is different from unsaturated polyester crosslinking method, and chemical bond is different, and various aspects of performance is all variant, its mutual compound rear interface performance and by cold cycling cracking be a difficult problem always.But castor oil glycidol ether, it is a kind of material with unsaturated double-bond and epoxy bond, and its carbochain is longer has good elasticity, it is in epoxy and unsaturated polyester interface, can be cross-linked with epoxy and unsaturated polyester, become intermediate interface material, well can improve interface performance and the cold cycling cracking phenomena of epoxy and unsaturated polyester.
Description
Technical field
The utility model relates to a kind of technical field of step, especially relates to a kind of carbon fiber compound step.
Background technology
Existing step runs in moving staircase girders cocycle, and for the parts that passenger stands, popular says, step is the lorry of the special structure form supplying passenger to stand.The main wheel wheel shaft of each step, together with step chains kink, can accomplish that step is in top set's maintenance level, overturns at inferior division like this.Because step quantity is many, be again movable parts, therefore the quality of escalator Performance and quality depends on the quality and performance of step to a great extent.
Step has integral type and assembly type two kinds.Integral type is formed by aluminum alloy integral die-cast, and its precision is high, and from heavy and light, process velocity is high, replaces assembly type step gradually.Assembly type step is formed by part assembling combination such as pedal, kickplate, supports, weight large (under pedal lined steel plate), low precision, be die casting ability less time product, will be replaced by integral type step gradually.The physical dimension of step comprises: step width, the step degree of depth i.e. tread depths, main wheel and jockey pulley cardinal distance, gauge i.e. main wheel spacing and step.Standard-required: the width (nominal width of escalator) of step should not be less than 0.58m and be no more than 1.1m; The degree of depth of step should be not less than 0.38m; The distance (rise) of upper and lower two step treads of being in operation should more than 0.24m.Step should carry out beaming test, i.e. (under have billet) vertical power applying 3000N on the area of tread 0.2m × 0.3m, and the amount of deflection of generation should be not more than 4mm, and without permanent deformation.And connect the load of bearing 6000 Ns/sq m at work, do not affect normal operation, therefore mainly corrosion-resistant steel compound step and aluminum casting is adopted, and existing step material is due to the defect in design, there is elevator casualty accident in its resistance to abrasion and fatigue durability poor causing, has great potential safety hazard.
Utility model content
The purpose of this utility model is the problem solving above-mentioned proposition, provides a kind of a kind of carbon fiber compound step improving step resistance to abrasion and fatigue durability.
The purpose of this utility model realizes as follows: a kind of carbon fiber compound step, there is composite bed, described composite bed is by three-decker, ground floor comprises common unsaturated polyester SMC layer by epoxy wear-resisting SMC layer, third layer, is be composited by castor oil three-glycidyl ether layer between described ground floor and third layer.
Further prioritization scheme is, above-mentioned a kind of carbon fiber compound step, and the wear-resisting SMC layer of described epoxy comprises high durable epoxy resin layer, carbon fiber layer, wear resistant filler layer and solidification oxidant layer and is composited; Adopt carbon fiber layer can improve the slight of material and elasticity by actv. in this formula, and technical maturity.
Further prioritization scheme is, above-mentioned a kind of carbon fiber compound step, and described common unsaturated polyester SMC layer comprises unsaturated polyester layer, carbon fiber layer and solidification oxidant layer successively and is composited.Adopt carbon fiber layer can improve the slight of material and elasticity by actv. in this formula, and technical maturity.
Further prioritization scheme is, above-mentioned a kind of carbon fiber compound step, and described composite bed is compressing by carrying press-forming machine, and its temperature is 165 DEG C; Adopt such temperature to be conducive to economize energy, reduce energy consumption.
Further prioritization scheme is, above-mentioned a kind of carbon fiber compound step, and described epoxy wear-resisting SMC layer and common unsaturated polyester SMC layer adopt SMC to produce.This auto-processes degree is high, and technical maturity is stablized.
Further prioritization scheme is, above-mentioned a kind of carbon fiber compound step, and described wear resistant filler layer comprises carborundum, aluminium oxide and monox and forms; Such wear resistant filler produces synergism mutually, both resistance to abrasion was added, turn increase the mechanical characteristics of composite material, adding of nano silicon oxide forms elasticity and the mechanical property that island effect adds epoxy resin in the epoxy, and adds its resistance to abrasion.
Advantage of the present utility model: 1, epoxy resin is different from unsaturated polyester crosslinking method, chemical bond is different, and various aspects of performance is all variant, its mutual compound rear interface performance and be always a difficult problem by cold cycling cracking.But castor oil glycidol ether, it is a kind of material with unsaturated double-bond and epoxy bond, and its carbochain is longer has good elasticity, it is in epoxy and unsaturated polyester interface, can be cross-linked with epoxy and unsaturated polyester, become intermediate interface material, well can improve interface performance and the cold cycling cracking phenomena of epoxy and unsaturated polyester.
2, the performance of castor oil three-glycidyl ether layer is better, can be good at link ground floor and third layer, makes the stability of whole step high.
