Description
Technical field
The present invention relates to a kind of wirerope, specially a kind of special steel wire rope for elevator.
Background technique
Currently, as the height of floor rises, the speed of service of elevator is gradually accelerated, to wirerope in elevator industry
It is required that also higher and higher, the elevator that some load-carryings are big, the speed of service is fast, it is desirable that the bearing capacity and wear-resisting property of wirerope will
It is good, although and the diameter that increases wirerope can improve the bearing capacity and wear-resisting property of wirerope, greatly enhance
The operating cost of elevator, wastes material, since the frequent use of elevator is made so that the steel wire of wirerope outer layer strand is easy to wear
At fracture of wire or stranded, the service life of wirerope is shortened, and reduce the safety of elevator, therefore we make this and change
Into proposing a kind of special steel wire rope for elevator.
Summary of the invention
To solve the frequent use of the existing technology due to elevator, so that the steel wire of wirerope outer layer strand is easy to wear,
Fracture of wire or stranded is caused, the defect of the service life of wirerope is shortened, the present invention provides a kind of special steel wire rope for elevator.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A kind of special steel wire rope for elevator of the invention, including eight outer layer strands, eight central strands and internal layer stock, eight are in
It is coated with internal layer stock inside equally distributed outer layer strand, is coated with eight between eight outer layer strands being evenly distributed and internal layer stock
The central strand being evenly distributed, the inside of each outer layer strand are coated with eight outer layer silks being evenly distributed, and eight in equal
The inside of the outer layer silk of even distribution is coated with eight PPC nylon yarns being evenly distributed, the inside packet of eight PPC nylon yarns
It is covered with internal layer silk, the surface of each outer layer strand is equipped with rubber layer, and the outer cover of eight outer layer strands is equipped with casing.
Further, the outer layer strand is using left-hand with twisting, and internal layer stock is twisted using dextrad is same, the outer layer strand and internal layer stock
Submit misloading circumferentially.
Further, the internal layer stock is that in line, touchingly cover wire packet twirl core wire is formed by the six roots of sensation.
Further, the central strand is formed by a central hair and six roots of sensation outer layer twisted filament twisting.
Further, the outer layer strand, central strand and internal layer stock pass through roll-in, die drawing into the well-regulated steel wire of abnormity.
Further, the top of described sleeve pipe is set there are two fixinig plate, and two fixinig plates are consolidated by clamping screw
It is fixed.
Compared with prior art, the invention has the following beneficial effects: this kind of steel wire rope for elevator, can be right by casing
Wirerope is clamped, and the contact surface for keeping the outer layer strand, central strand and internal layer stock of wirerope mutual forms compacting stock, is prevented
The length of steel rope time is separated from each other using outer layer strand, central strand and internal layer stock, influences the fastness of wirerope, and high-intensitive pressure resistance
The grease that contains of PPC nylon yarn its lubricant effect can be made to retain the longer time, reduce the abrasion of wirerope, increase
Its fatigue performance, the rubber layer that outer layer strand surface is equipped with can protect the hand of staff, prevent outer layer strand
Steel wire fracture is caused to stab or be frayed to the hand of staff, and internal layer stock is that in line, touchingly cover wire packet is twisted by the six roots of sensation
Core wire forms, central strand is formed by a central hair and six roots of sensation outer layer twisted filament twisting, compares hemp center wireline, mentions significantly
The high rupture pull force of wirerope and the uniformity of rope diameter poker.

Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in Figure 1, a kind of special steel wire rope for elevator, including eight outer layer strands, 1, eight central strand 2 and internal layer stock
3, be coated with internal layer stock 3 inside eight outer layer strands 1 being evenly distributed, eight outer layer strands 1 being evenly distributed and internal layer stock 3 it
Between be coated with eight central strands being evenly distributed 2, the inside of each outer layer strand 1 is coated with eight outer layer silks being evenly distributed
4, the inside of eight outer layer silks 4 being evenly distributed is coated with eight PPC nylon yarns 5 being evenly distributed, eight PPC nylon yarns
5 inside is coated with internal layer silk 6, and the surface of each outer layer strand 1 is equipped with rubber layer, and the outer cover of eight outer layer strands 1 is equipped with casing
7。
Wherein, outer layer strand 1 is using left-hand with twisting, and for internal layer stock 3 using dextrad with twisting, outer layer strand 1 and internal layer stock 3 submit misloading
Circumferentially, the contact surface for making the outer layer strand 1, central strand 2 and internal layer stock 3 of wirerope mutual forms compacting stock.
Wherein, internal layer stock 3 is that in line, touchingly cover wire packet twirl core wire is formed by the six roots of sensation, substantially increases steel
The rupture pull force of cord and the uniformity of rope diameter poker.
Wherein, central strand 2 is formed by a central hair and six roots of sensation outer layer twisted filament twisting, substantially increases the broken of wirerope
The uniformity of disconnected pulling force and diameter poker of restricting.
Wherein, outer layer strand 1, central strand 2 and internal layer stock 3 make mutually by roll-in, die drawing at the well-regulated steel wire of abnormity
Between contact surface formed compacting stock.
Wherein, the top of casing 7 is set there are two fixinig plate 8, and two fixinig plates 8 are fixed by clamping screw 9, right
Wirerope is clamped, and the contact surface for keeping the outer layer strand 1, central strand 2 and internal layer stock 3 of wirerope mutual forms compacting stock,
It prevents the length of steel rope time to be separated from each other using outer layer strand 1, central strand 2 and internal layer stock 3, influences the fastness of wirerope.
It should be noted that the present invention is a kind of special steel wire rope for elevator, when specific works, according to the straight of wirerope
7 sets of the casing outsides in wirerope are fixed by the fixinig plate 8 that clamping screw 9 is equipped with 7 top of casing, make steel by diameter
The outer layer strand 1 of cord, central strand 2 and the mutual contact surface of internal layer stock 3 form compacting stock, prevent the length of steel rope time from using
Outer layer strand 1, central strand 2 and internal layer stock 3 are separated from each other, and influence the fastness of wirerope, and internal layer stock 3 is to be contacted by the six roots of sensation in line
Shape cover wire packet twist core wire forms, central strand 2 is formed by a central hair and six roots of sensation outer layer twisted filament twisting, comparison
Hemp center wireline substantially increases the rupture pull force of wirerope and the uniformity of rope diameter poker, the rubber that 1 surface of outer layer strand is equipped with
Layer can protect the hand of staff, prevent the steel wire fracture of outer layer strand 1 from causing to stab to the hand of staff
Or it frays, and the grease that the PPC nylon yarn 5 of high-intensitive pressure resistance contains can make its lubricant effect retain the longer time, reduce
The abrasion of wirerope, increases its fatigue performance.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
