Description
Technical field
The present invention relates to a kind of elevator traction suspension for elevator.
Background technique
Chinese patent CN101044084B discloses the elevator with the flat belt as load carrier, on belt
The cooperation that guiding rib on guide groove and belt pulley is constituted is fallen off in flat belt sliding and slave pulley with overcoming or is damaged in advance
Bad defect.But there is also some disadvantages for the technical solution of the patent: (1) guiding rib of belt pulley requires machining accuracy high,
Material cost is high；(2) thickness of belt at the guide groove of belt is thin, in the process of running, if the guiding rib and skin of belt pulley
The guide groove cooperation of band is bad, and side is excessive by pressure, may cause the disconnected band of Flat belt or the service life greatly shortens.
Chinese patent CN204138090U discloses the traction suspension line for elevator, the side work of the traction suspension line
Face is plane, which is equipped with several regulating tanks arranged along its length, and other side working face is equipped with multiple along length
The convex ribs of direction arrangement, the patent solve the problems, such as the noise problem of traction surplus and traction suspension line and directive wheel.
But the patent is the shortcomings that still remaining: the rope sheave working face processing with suspension line with convex ribs one side is cumbersome, matches with it
Pair directive wheel cooperation precision it is high, processing cost is high；Traction suspension line cooperates bad, the side of traction suspension line with directive wheel
It is excessive to bear pressure, may cause disconnected band or greatly shortens traction suspension line service life.
Summary of the invention
In view of this, the purpose of the present invention is overcoming the deficiencies of existing technologies, provide that a kind of processing cost is lower, and traction is held
The not easily broken band of carrier unit, uses more reliable elevator traction suspension.
In order to achieve the above objectives, the present invention provides a kind of elevator traction suspension, including traction sheave, directive wheel and with
The traction load bearing unit of the traction sheave and directive wheel cooperation, the traction load bearing unit are used to carrying and moving carriage,
The traction load bearing unit is flat belt-like and has the first working face and the second working face, it is characterised in that: first work
The both sides of the edge for making face, which are respectively provided between guide way outstanding on first working face, the guide way of two sides, to be formed
For the traction race of traction sheave insertion cooperation；Bossy body is equipped on second working face between both sides of the edge, it is described
The guide groove with bossy body cooperation is offered on directive wheel.
Preferably, the traction load bearing unit includes the package for carrying tension element and being wrapped in except the carrying tension element
Body, the inclusion enclave be thermoplastic polyurethane elastomer rubber (TPU), nitrile rubber or ethylene propylene diene rubber (EPDM) wherein
One kind, the carrying tension element have for the one of which or both of which of steel core or carbon fiber.Inclusion enclave is rubber integrated molding,
The molding of bossy body in this way is more easier, and processing cost is lower.And in traditional structure, belt pulley is metal structure, is wanted on it
Guiding rib is made, needs to carry out high-precision metal machining, cumbersome, processing cost is high.
It is highly preferred that the more carrying tension elements are alternatively arranged point in the width direction of the traction load bearing unit
Cloth, the more carrying tension elements all use steel core or all using carbon fiber or the more carrying tension element alternatings
It carries out being alternatively arranged arrangement by the way of steel core and carbon fiber.
Preferably, the cross-sectional shape of the guide way is that triangle, trapezoidal, semicircle, minor arc arch or number of edges are greater than 4
Polygon.
It is highly preferred that the traction sheave insertion cooperates at the centre of traction race, the guide way of two sides and the traction
The first width fits gap d is respectively provided between wheel, the first width fits gap d is 0.3-3mm.
Preferably, the cross-sectional shape of the bossy body is that triangle, trapezoidal, semicircle, minor arc arch or number of edges are greater than 4
Polygon.
It is highly preferred that the cross-sectional shape phase complementary fit of the cross-sectional shape of the guide groove and the bossy body.Phase
Complementary fit refers to: when the cross section of bossy body is triangle, the cross-sectional shape of guide groove is also compatible triangle；It is convex
When the cross section of body is trapezoidal out, the cross-sectional shape of guide groove is also compatible trapezoidal；And so on.
Preferably, bossy body (8) the insertion cooperation is at the centre of the guide groove (5), and the two of the bossy body (8)
All having the second width fits gap b, second width fits gap b between side and the guide groove (5) respectively is 0.3-
3mm。
In a specific embodiment, the bossy body only has 1, and is located at the second working face of traction load bearing unit
Centre.
Preferably, the outer surface of the inner surface of the guide groove and/or the guide way, which has, reduces friction and wear
Protective layer.The protective layer is polytetrafluoroethylene ethylene layer, perfluoroalkoxy base, ceramic layer or the coat of metal.
Due to the adoption of the above technical scheme, the present invention reaches following technical effect:
(1) by the guide way of the both sides of the edge setting protrusion of the first working face of the traction load bearing unit of bandlet shape, two sides
Guide way between form traction race, when cooperating the first working face and traction sheave, traction sheave is located in the traction race, leads
Guiding role is played to body, avoids the sliding of traction load bearing unit；
(2) it is provided with bossy body on the second working face, the guide groove with bossy body cooperation is set on directive wheel, when
When second working face and guide groove contact, bossy body cooperates in guide groove, and guide groove plays guiding to traction load bearing unit and makees
With avoiding the sliding of traction load bearing unit；
(3) guide way and bossy body enhance the intensity of flat banded structure itself, the less easily broken band of use；On the other hand,
The integrated molding processing method of bossy body is set on traction load bearing unit than making adding for guiding rib on directive wheel outer circumference surface
Work mode is easier, and processing cost is lower.
Elevator traction suspension of the invention can be used in the various elevator devices of traction ratio 2:1 or 4:1.Compared to existing
Some elevator traction suspension, structure design of the invention is more succinct, and use is more safe and reliable, and processing cost is more
It is low.
