Description
Technical field
The present invention relates to the design of escalator components and production technical field are and in particular to escalator and pavement
And the manufacture of the handrail of other transportation facilities use, it is a kind of production method of thermoplastic material elevator handrail.
Background technology
The development of society, growth in the living standard makes the range of application of escalator increasing: market, airport, train
Stand, subway station, library, exhibition center, the hospital of upper scale etc..Originally the escalator in Shanghai City first department store becomes
For the memory that people are happy.
Escalator has to use handrail.Handrail is the building block of escalator and pavement.This
It is in " ω " shape outside handrail, such that it is able to be grasped by user；There is " t " font groove such that it is able to and elevator inside handrail
T shape guide rail agree with, slide glibly.Automatic staircase handrail band must possess longitudinal stretch-resistance, anti-flexibility and laterally
Intensity: (1) in the environment of elevator operation, if longitudinally not having enough tensile resistences, the length of escalator handrail can be with making
Elongated with the passage of time it may appear that handrail departs from the risk of cage guide；(2) handrail is by being pressed by driving wheel
Surface produces frictional force to operate, and handrail can circuitously pass through driving wheel and several auxiliary wheel forms 3 dot structures, thus
Meeting larger the deflecting of producing ratio, this is accomplished by handrail has than larger anti-flexibility and pliability；(3) due in handrail
The t shape groove in portion and agreeing with of cage guide, can make handrail slidably not fall off on elevator for a long time, this is just
Need handrail to have the tension intensity at enough transverse strengths and " ω " shape opening, prevent transverse strength not in " ω " shape
Easily become big at opening and handrail displacement or derailment occurring occur.
Earliest, the handrail of escalator is to draw strong steel wire and multilayer rubber folded structures to constitute by fabric base band, multiply
's.Manufactured by the way of sulfuration molding: the first step: molding, rubberized fabrics, steel wire and each layer raw rubber are stacked together,
Form the structure that a cross section is similar to sandwich；It is wrapped in a t shape mould and fixed with a clevis so as to completely again
Laminating t shape mould；Second step: sulfuration, the material after molding is put in the mould that cross section is " ω " shape, in heating and pressure
In the presence of sulfidization molding, formed there is " ω " shape outline, the interior handrail having " t " shape groove.Due to rubber limited source,
High cost；Mold pressing procedure in manufacture is not easy to continuously manufacture；And outmoded rubber handrail band is not easy to recycling etc. no
Sufficient, people gradually replaced, with thermoplastic material, the handrail that rubber manufactures escalator later, and not only raw material sources are wide, low cost,
And facilitating the continuous production of handrail, outmoded plastic handrail band is also convenient for recycling.But, existing plastic handrail band
Production method still continued to use the technique of rubber handrail band " molding ", be by fabric base band, strengthen wire rope and heat-stabilized wood
Flat panel substrates first made by material, and then reheating is processed into the handrail of c type structure, and not only step is many, and equipment is many, and imitates accordingly
Rate is not high.
