Technical field
The utility model belongs to elevator component technology field, is specifically related to a kind of hoisting rope for elevator, and relates to this hoisting rope for elevator elevator traction sheave used.
Background technology
Previously, conventionally by the car of rope traction elevator, and according to design regulation requirement, the diameter of steel rope can not be less than 8 ㎜, and the diameter of rope sheave can not be less than 40 times of wirerope diameter, so diameter of steel rope larger (along with the change of payload ratings is large), the diameter of rope sheave is also larger so, that is to say that rope sheave is keeping the relation of following in sb's footsteps with the variation of wirerope diameter under the satisfied prerequisite that is more than or equal to 40 times of wirerope diameters, only this is met the safety requirements that elevator moves up and down.But the aforementioned relation between steel rope and rope sheave is difficult to the miniaturization development that the volume of rope sheave is expected towards industry, can reduce the holistic cost of elevator and reduce taking of corresponding space because dwindle rope sheave volume.With in view of this, people have expected that use drawing belt replaces steel rope.
Technical information about hoisting rope for elevator is no lack of and is seen in disclosed Chinese patent literature, slightly with exemplify as the elevator band of CN101122097A(lift facility and manufacture the method for this elevator band), CN101122100A(is for the method for elevator band and this elevator band of manufacture of lift facility), CN101121302A(is for the belt of elevator device and the manufacture method of this belt), CN101663222A(elevator belt, produce the method for this elevator belt and there is the lift facility of this belt conveyor), CN102304863B(hoisting rope for elevator and manufacture method thereof) and CN101349023B(traction belt for elevator and drive method), etc..
Typically, as CN201825620U recommends to have " steel strip for elevator traction ", be made up of complex root steel strand and the composite layer being coated on outside complex root steel strand, this structural expression is the level and smooth no concave-convex in two sides; And for example CN102635005A provides " one is wrapped up in and moulded the flat drawing belt of carbon fiber elevator Special flat ", and this patent application scheme, for CN201825620U, changes steel strand into carbon fiber.Because the way of contact between drawing belt and the traction sheave of this structure shows as plane contact, thereby traction effect is difficult to meet the requirement that industry is expected." the one-sided shape elevator traction steel band of leading " that Granted publication CN203187270U introduces can make up the poor shortcoming of aforementioned traction effect of CN102635005A and CN201825620U, and objectively can embody the technique effect of the 0011st section to 0014 section of its specification sheets.
