Description
Technical field
The present invention relates to a kind of in elevator, transmit power and promote elevator traction bearing carrier and the elevator of car.
Background technology
In traction-type elevator, car and to perform relative motion Beijing South Maxpower Technology Co. Ltd be that the frictional force by between hoist ropes and traction sheave realizes.This power is just traction or driving force.And hoist ropes is exactly the one of which of elevator traction bearing carrier, the current elevator overwhelming majority uses steel wire rope as elevator traction bearing carrier.But, development along with elevator technology, elevator traction bearing carrier develops towards lightweight direction, traditional steel wire rope owing to there is quality weight, the shortcoming such as diameter is big and noise is big, and the elevator of light-weight design extremely limited for installing space cannot meet needs.In order to solve such problem, have been developed that the elevator traction bearing carrier such as steel wire rope such as steel core band and surface nonmetallic coating at present.But, due to or using steel core or steel wire rope as the main stress carrier in elevator traction bearing carrier, and the proportion of steel core or steel wire rope is the highest so that elevator traction bearing carrier is on the premise of meeting requirement of strength, it is difficult to yet further reduce own wt.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of requirement of strength that can meet elevator operation, the elevator traction bearing carrier of the light-weight design that weight can be alleviated as far as possible again, and use the elevator of this elevator traction bearing carrier.
For reaching above-mentioned purpose, the present invention provides a kind of elevator traction bearing carrier, including one or more traction load bearing units, it is characterized in that: each described traction load bearing unit includes polymeric substrate and at least non-metallic fibers silk extended continuously along the length direction of described traction load bearing unit being embedded in described polymeric substrate, described non-metallic fibers silk is glass fibre, carbon fiber or nylon fiber, and the diameter d of described non-metallic fibers silk is 3 μm-80 μm.

When the cross section of traction load bearing unit is regular polygon, a diameter of 1mm-8mm of the circumscribed circle of described regular polygon or the sectional area of described traction load bearing unit are 2.5 mm2-50 mm2。
Preferably, described traction load bearing unit is the tooth banded structure that there is tooth on the anodontia flat ribbon structure in surface or surface, the section thickness of described elevator traction bearing carrier is 0.1mm-4mm, and the cross-sectional width of described elevator traction bearing carrier is 10-250 times of described section thickness.
It is further preferred that the thickness of each described traction load bearing unit is 4 μm-4mm.
Wherein, described elevator traction bearing carrier is laminated by multiple described traction load bearing unit through-thickness or arrangement forms in the width direction.
Preferably, when described traction load bearing unit is tooth banded structure, at least a part of which one side of the upper and lower surface on the thickness direction of described traction load bearing unit has the tooth of projection.
More preferably, the two sides of the upper and lower surface on the thickness direction of described traction load bearing unit all has the tooth of projection, and the tooth on the most described upper surface and described lower surface is along the upper and lower symmetrical setting of thickness direction of described traction load bearing unit.
In another embodiment, the tooth on described upper surface and described lower surface is along the staggered setting of width of described traction load bearing unit.
Wherein, described polymeric substrate is epoxy resin, rubber, PU(polyurethane) one of which.Rubber preferably is selected from TPU(Polyurethane Thermoplastic Elastomer rubber), CR(neoprene) or EPDM(ethylene propylene diene rubber).
Use the non-metallic fibers silk of carbon fiber, glass fibre or nylon fiber as the main stress carrier in elevator traction bearing carrier, there is, intensity higher advantage lighter than steel wire weight.Such as, carbon fiber proportion is less than the 1/4 of steel, and tensile strength is 7-9 times of steel, and elastic modelling quantity is also above steel, as the main stress carrier in elevator traction load bearing unit, on the premise of meeting traction, it is possible to be substantially reduced the weight of elevator traction bearing carrier.Similarly, glass fibre and nylon fiber also have lighter than steel weight, tensile strength is bigger, the higher advantage of elastic modelling quantity.Meanwhile, the present invention is to solve the problem that non-metallic fibers silk wears no resistance, non-metallic fibers silk is embedded in the polymeric substrate that anti-wear performance is good, solve wear-resisting problem, elevator traction bearing carrier can be reduced again in use because of fricative noise.
Further improve as the present invention, present invention also offers a kind of elevator, the car that including driving means, there is car directive wheel, the counterweight with counterweight directive wheel, it is characterized in that: also include that above-mentioned elevator traction bearing carrier, described elevator traction bearing carrier are wound on described car directive wheel, described driving means and described counterweight directive wheel.Use the elevator of above-mentioned elevator traction bearing carrier, enable elevator lay-out more to adapt to compact building hoistway, improve elevator comfortableness.
Compared to prior art, the present invention is on the premise of meeting elevator traction unit safety requirements, and non-metallic fibers silk is introduced elevator traction bearing carrier, it is achieved thereby that the more light-weight design of elevator traction bearing carrier.The elevator traction bearing carrier of the present invention, under the requirement of strength meeting elevator traction power, greatly reduces the weight of elevator traction bearing carrier, reduces elevator traction bearing carrier noise in use.Use the elevator of the elevator traction bearing carrier of the such light-weight design of the present invention, it is possible to more adapt to compact building hoistway, thus improve elevator and run comfort level, make enterprise competitiveness strengthen.
