Description
Technical field
The present invention relates to a kind of hoisting rope for elevator to belong to transmission belt manufacture more particularly, to a kind of composite elevator drawing belt
Technical field.
Background technique
Currently, building trade with energy conservation, lightweight, miniaturization, turn to development trend at a high speed, elevator is indispensable as building
Few part, structure and its building arrangements propose higher more advanced requirement.Particularly low noise is developed on traction medium
Sound, lightweight, small room design concept, the big Design of Machine Room of traditional wirerope are gradually eliminated.
Chinese patent CN104528498A discloses a kind of drawing belt of composite material, by more internal supporting body and packet
The wear-resistant elastomeric composition being overlying on outside more internal supporting body, internal supporting body are unidirectionally continuous along drawing belt length direction
Sheet；Internal supporting body includes matrix, and intrinsic silicon has more nonmetallic non-twist continuous monofilaments, more non-twist continuous fiber lists
Contactless between silk, the matrix of every layer of internal supporting body is thermoset resin material or thermoplastic resin material, wear-resistant elastomeric
For thermo-plastic polyurethane or rubber elastomer, the invention by setting multilayer chip composite material as drawing belt inside supporting body,
Under the premise of realizing the good carrying of guarantee, reduces drawing belt bending radius, increase flexibility, but the drawing belt preparation in the invention
Complex process, compared to the present invention, wheel footpath of turning is still larger, is unfavorable for the reduction of traction shaft diameter.

The weight of leader tape.
Load-carrying unit can also be drawing belt common load-carrying unit, such as carbon fiber, glass fibre etc..
The clad bottom with a thickness of 1~4, preferably 1mm；The clad is thermoplastic urethane layers；Thermoplastic
Property layer of polyurethane hardness be 70-100A.
The thickness of the thermoplastic urethane layers can be 3-5mm.
The material of the clad can also use other wear-resistant elastomerics, such as rubber elastomer.
The drawing belt back side is matte structure, advantageously reduces frictional force.
The composite elevator drawing belt has high flexibility.
Compared with prior art, the present invention is provided with specific pattern structure in traction belt surface, and specially more wedge shapes are disconnected
Tooth type structures play guiding role by the way that this structure wedge shape is arranged, make drawing belt that deviation phenomenon not occur, broken teeth structure can be bright
The aobvious turning wheel footpath (reducing traction machine traction shaft diameter) for reducing drawing belt.
The invention patent product is compound using aramid fiber and Thermoplastic polyurethane elastomer material, replaces traction steel wire completely
Rope, so that spies such as drawing belt have light weight, high intensity, flexible, wear-resisting, weather-proof, antifatigue, the service life is long, maintenance cost is low
Point, meanwhile, the traction shaft diameter of outfit is even more to narrow down to 40mm or so, saves Design of Machine Room, saves space, greatly reduces
Building cost；The compound drawing belt has resistance to circumnutating property good, and the service life of compound drawing belt is 5 times of left sides of traditional wirerope
It is right.Aramid fiber has the characteristics that low elongation, high-modulus, is better than wirerope, and furthermore compound traction steel band has low noise, matter
Amount is light, energy conservation, exempts from that lubrication etc. is many advantage.
