Description
Technical field
The present invention relates to a kind of technical field of step, especially relate to a kind of carbon fiber and be combined step.
Background technology
Existing step is circular flow on moving staircase girders, the part stood for passenger, and popular says, step is to supply passenger
The lorry of the special structure form stood.The main wheel wheel shaft of each step, together with step chains kink, so can accomplish ladder
Level keeps level in top set, is overturn in inferior division.Because step quantity is many, it is moving component again, therefore escalator
The quality of performance and quality is heavily dependent on quality and the performance of step.
Step has monoblock type and two kinds of assembled.Monoblock type is formed by aluminium alloy integral die-cast, its high precision, from heavy and light, processes
Speed is high, is gradually replacing assembled step.Assembled step is formed by the part assembling combination such as pedal, kickplate, support,
Weight is big (lined steel plate under pedal), and low precision is product when die casting ability is less, will gradually be replaced by monoblock type step.
The physical dimension of step includes：Step width, step depth i.e. tread depths, main wheel and jockey pulley cardinal distance, gauge are namely
Main wheel spacing and step.Standard requires：The width (nominal width of escalator) of step is no less than 0.58m and not
More than 1.1m；The depth of step should be not less than 0.38m；Be in operation upper and lower two step treads distance (rise) should
More than 0.24m.Step should carry out beam test, and that is, on the area of tread 0.2m × 0.3m, (under have billet) is vertical applies
The power of 3000N, the amount of deflection of generation should be not more than 4mm, and no permanent deformation.And 6000 Ns/square metre are born in connection at work
Load, do not affect normally to run, therefore mainly adopt rustless steel to be combined step and aluminum casting, and existing step material due to
Defect in design, its wearability and fatigue durability are poor to lead to elevator casualty accident, has great potential safety hazard.
Content of the invention
Present invention aim to address problem set forth above, provide a kind of a kind of carbon fibre improving step wearability and fatigue durability
The compound step of dimension.
The purpose of the present invention is realized as follows：A kind of carbon fiber is combined step, has composite bed, and described composite bed is
By three-decker, ground floor is to include common unsaturated-resin SMC layer by epoxy wear-resisting SMC layer, third layer, described ground floor with
It is to be composited by Oleum Ricini three-glycidyl ether layer between third layer.
Further prioritization scheme is, above-mentioned carbon fiber is combined step, and the wear-resisting SMC layer of described epoxy includes high durable epoxy
Resin bed, carbon fiber layer, wear resistant filler layer and solidification oxidant layer are composited；Can effectively be carried using carbon fiber layer in this formula
The slight and pliability of high material, and technical maturity.
Further prioritization scheme is, above-mentioned carbon fiber is combined step, and described common unsaturated-resin SMC layer includes successively
Unsaturated-resin layer, carbon fiber layer and solidification oxidant layer are composited.In this formula, material can effectively be improved using carbon fiber layer
Slight and pliability, and technical maturity.
Further prioritization scheme is, above-mentioned carbon fiber is combined step, and described composite bed is by putting forward press-forming machine pressure
Make type, its temperature is 165 DEG C；Energy saving, reducing energy consumption are conducive to using such temperature.
Further prioritization scheme is, above-mentioned carbon fiber is combined step, the wear-resisting SMC layer of described epoxy and commonly unsaturated set
Fat SMC layer adopts SMC to produce.This auto-processes degree is high, and technical maturity is stable.
Further prioritization scheme is, above-mentioned carbon fiber is combined step, and described wear resistant filler layer includes carborundum, aluminium oxide
Constitute with silicon oxide；Such wear resistant filler mutually produces synergism, both increased wearability, increased composite again
Mechanical performance, the addition of nano silicon oxide forms pliability and the mechanical property that island effect increased epoxy resin in the epoxy
Can, and increased its wearability.
Advantages of the present invention：1st, epoxy resin is different from unsaturated-resin crosslinking method, and chemical bond is different, and various aspects of performance
All variant, it is combined mutually rear interface performance and is always a difficult problem by cold cycling cracking.But Oleum Ricini glycidyl ether, be
A kind of material with unsaturated double-bond and epoxy bond, and its carbochain is longer has good pliability, it is between epoxy and insatiable hunger
In resin boundary surface, can be crosslinked with epoxy and unsaturated-resin, become intermediate interface material, epoxy and insatiable hunger can be improved well
Interface performance and cold cycling cracking phenomena with resin.
2nd, the performance of Oleum Ricini three-glycidyl ether layer more preferably, can be good at linking ground floor and third layer so that whole ladder
The stability of level is high.
