Description
Technical field
This utility model relates to a kind of elevator dragging hanging apparatus promoting car in elevator and elevator.
Background technology
Chinese patent CN101044084B discloses the elevator with the flat belt as load carrier, on its belt
The cooperation that guiding rib on gathering sill and belt pulley is constituted, to overcome flat belt sliding and come off from belt pulley or damage in advance
Bad defect.But the technical scheme of this patent there is also some shortcomings: the guiding rib of (1) belt pulley requires that machining accuracy is high,
Material cost is high；(2) thickness of belt at the gathering sill of belt is thin, in running, if the guiding rib of belt pulley and skin
The gathering sill of band coordinates bad, and side is stressed excessive, and Flat belt broken belt or life-span may be caused to be greatly shortened.
Summary of the invention
In view of this, the purpose of this utility model is the defect overcoming prior art, it is provided that a kind of processing cost is relatively low, no
Easily broken belt, uses more reliable elevator dragging hanging apparatus and uses its elevator.
For reaching above-mentioned purpose, this utility model provides a kind of elevator dragging hanging apparatus, including traction supporting body, respectively
The traction sheave coordinated with described traction supporting body and directive wheel, described traction supporting body is used for carrying and moving car, described in drag
Draw supporting body to be flat belt-like and be respectively provided with the first work surface coordinated with described traction sheave and coordinate with described directive wheel
Second work surface, it is characterised in that: described first work surface is provided with one or more the first bossy body, described traction sheave
Outer circumference surface is provided with the first gathering sill coordinated with described first bossy body one_to_one corresponding；It is provided only with on described second work surface
One the second bossy body, the outer circumference surface of described directive wheel has second guiding coordinated with described second bossy body
Groove.
Preferably, the first bossy body on the first work surface of traction supporting body and the second bossy body on the second work surface
Mutually stagger setting.
Preferably, described traction supporting body includes the parcel outside carrying tension element and being wrapped in described carrying tension element
Body, described inclusion enclave be Polyurethane Thermoplastic Elastomer rubber (TPU), nitrile rubber or ethylene propylene diene rubber (EPDM) wherein
One, described carrying tension element is steel core or the one of which of carbon fiber or both of which has.Inclusion enclave is that rubber is one-body molded,
So molding of bossy body is more prone to, and processing cost is lower.And in traditional structure, belt pulley is metal structure, want thereon
Making guiding rib, need to carry out high-precision metal machining, cumbersome, processing cost is high.The outer surface of bossy body and institute
State, between the inner surface of gathering sill, there is gap, also reduce the requirement on machining accuracy of the two, reduce processing cost.
It is highly preferred that many described carrying tension elements are spaced distribution on the width of described traction supporting body,
Many described carrying tension elements all use steel core or all use carbon fiber, or many described carrying tension elements alternately use
The mode of steel core and carbon fiber carries out being spaced layout.
Preferably, the shape of cross section of described first bossy body and described second bossy body be respectively selected from trapezoidal, triangle,
Semicircle or that limit number is more than 4 polygonal one of which.
It is highly preferred that the shape of cross section of described first gathering sill is mutually complementary with the shape of cross section of described first bossy body
Coordinate；The shape of cross section phase complementary fit of the shape of cross section of described second gathering sill and described second bossy body.Complementary mutually
Cooperation refers to: when the cross section of bossy body is triangle, and the shape of cross section of corresponding gathering sill is also suitable triangle；
When the cross section of bossy body is trapezoidal, the shape of cross section of corresponding gathering sill is also suitable trapezoidal；The like.
Wherein, on described first work surface, the surface area sum of all the first described bossy bodies is less than described first
The 30% of the surface area of work surface；On described second work surface, the surface area of the second described bossy body is less than described second work

Between the inner surface of face and the second gathering sill 52, there is gap.After second bossy body 42 embeds the second gathering sill 52, between the two
Having gap, gap includes axial gap and radial clearance.Second bossy body 42 of traction supporting body 2 and the second gathering sill 52 are not
Contact, only when traction supporting body 2 is oppositely oriented wheel 8 lateral shift, the second bossy body 42 and the second gathering sill 52 are in side
Contact, play the guiding role, thus avoid discontinuity cause the second bossy body 42 abrasion thus affect whole traction carrying
The life-span of body 2.
Wherein, on the first work surface 21, the surface area sum of all of first bossy body 41 is less than the first work surface 21
Surface area 30%.On the second work surface 21, the surface area of the second bossy body 42 is less than the surface area of the second work surface 22
30%.In the present embodiment, the first work surface 21 of traction supporting body 2 coordinates with traction sheave 1, and traction sheave 1 offers two first
Gathering sill 51, the first work surface 22 of traction supporting body 2 is correspondingly provided with two the first bossy bodies 41, two the first bossy bodies 41
Surface area sum less than the first work surface 21 area 30%.Thus it is ensured that most of area that work surface is more than 70% is used
Contact in the rolling surface with traction sheave 1, force dispersion when making the traction supporting body 2 of bandlet shape coordinate with traction sheave 1, it is to avoid traction
Supporting body 2 local pressure is excessive and easy broken belt, it is ensured that safe and reliable.
Similarly, the surface area of second bossy body 42 of the second work surface 22 of the traction supporting body 2 of the present embodiment
Again smaller than the area of the second work surface 22 30%, it is to avoid when traction supporting body 2 coordinates with directive wheel 8, local pressure is excessive and hold
Easily broken belt, it is ensured that safe and reliable.
In the present embodiment, the inner surface of the first gathering sill 51 and the second gathering sill 52 all has and reduces friction and wear
Protective layer 53.Preferably, protective layer 53 can be its of polytetrafluoroethylene floor, perfluoroalkoxy basic unit, ceramic layer or the coat of metal
Middle one.
Embodiment two
Referring to Fig. 3, the present embodiment is with the difference of embodiment one: the horizontal stroke of first bossy body the 41, first gathering sill 51
Cross sectional shape is triangle；The shape of cross section of the second bossy body 42 is also triangle.
Embodiment three
Referring to Fig. 4, the shape of cross section of first bossy body the 41, first gathering sill 51 is semicircle；Second bossy body
