Description
Technical field
The utility model relates to a kind of elevator ropes being suitably mounted in lift appliance, further relate to a kind of for fixing
The connector of elevator polymer-coated steel cable.
Background technique
Elevator generally passes through dragged wire-rope and is respectively fixedly connected with carriage and to pouring weight, by dragged wire-rope and traction sheave rope groove
Between frictional force drive the carriage to go up and down.
Dragged wire-rope and lift car to the connection of pouring weight are realized by connector.Existing connector is wedge
Shape connector, such as GB/T5973-2006 " wirerope wedge joint ".
However the wedge joint and it is not suitable for all dragged wire-ropes.The steel cable of traditional non-polymer coat is come
It says, since significant change will not occur in use for the diameter of steel cable, which can be good at fixed steel cable.But
For the steel cable with polymer-coated layer, in use due to steel cable, due to the influence of some adverse circumstances, steel
There is the risk that softening or missing occurs in the polymer-coated layer of rope, therefore the diameter of steel cable may change, then position
Steel cable inside wedge joint may be pulled out from wedge joint.
Utility model content
The utility model primary and foremost purpose is to solve above-mentioned problem of the prior art.
One of the purpose of this utility model, which is to provide, a kind of connects stronger safer elevator rope.
Another purpose of the utility model be to provide it is a kind of for more applicable fixed polymer coating steel cable in elevator
Connector in device.
Purpose according to the present utility model provides a kind of elevator rope being suitably mounted in lift appliance.Elevator ropes
Rope includes the steel cable of polymer-coated, and end to the elevator that one or two connector is used to connect the steel cable of polymer-coated fills
It sets, each of one or two connector includes a wedge-shaped sleeve and a wedge block, and there is wedge-shaped sleeve a cavity to be used to
An end of the steel cable of wedge block and polymer-coated is received, wedge block has side in a thickness direction, and wedge block exists
At least part of side is equipped with the end that guide groove is used to keep the steel cable of polymer-coated, which is characterized in that guide groove has width
Wg, unit mm are spent, wedge block has thickness Tw, and the ratio of unit mm, Wg and Tw are between 0.38-0.67.
Compared to existing wedge joint, it is used to keep the guide groove of steel cable in the connector of the utility model on wedge block
Depth is shallower, this makes the contact pressure between the guide groove on steel cable and wedge-shaped sleeve inner wall and wedge block become larger so that steel cable with
Frictional force between connector becomes larger, and steel cable can be fixed more firmly.And even if the polymer-coated layer of steel cable falls off,
Since guide groove is shallower, steel cable still can be firmly fixed between wedge-shaped sleeve and wedge block, will not be because of polymer-coated
Layer falls off and steel cable is caused to fall off.Therefore elevator rope is safer.
Preferably, the ratio of Wg and Tw is between 0.45-0.56.
Preferably, guide groove has a shape of arc in its cross section, radius of curvature R, the radius of curvature R 0.30 ×
Within the scope of d to 0.52 × d, d is the diameter of the steel cable of polymer-coated, unit mm.It ensure that steel cable and guide groove with
And the polymer-coated layer between wedge-shaped sleeve inner wall in steel cable fall off after be still able to maintain very close contact.It is highly preferred that
Radius of curvature R is within the scope of 0.35 × d to 0.50 × d.
The side of wedge block in a thickness direction includes at least left side plane, right side plan and upper N-Side surf.Preferably,
Guide groove is straight, and passes through left side plane and right side plan with constant depth and run through upper N-Side surf.That is, only portion
The upper N-Side surf divided is equipped with guide groove, so that steel cable can generate bigger friction in the intersection of guide groove and upper N-Side surf
Power, steel cable can be preferably fixed, and reduce the risk of sliding.Alternately, guide groove is curved with constant depth
Spend the whole across left side plane and right side plan and upper N-Side surf.As another preferred embodiment, the thickness table of wedge block
Face has left side plane, right side plan, upper N-Side surf and underside plan, and guide groove is straight and passes through left side with constant depth
Plane, right side plan and partial curved surface or guide groove are curved and pass through left side plane, right side plan with constant depth
And the whole of curved surface.
Preferably, there is wedge-shaped sleeve an entrance to enter its cavity for wedge block, and the shape of entrance adapts to wedge block
The shape of shape, entrance has width Wo, and for Wo within the scope of (2.8d+Ww) to (4d+Ww), Ww is the width of wedge block,
Namely the distance between the upper N-Side surf two-end-point of wedge block, unit mm.Compared to the wedge-shaped sleeve of existing wedge joint
Opening, the wedge-shaped sleeve opening of connector is bigger in the utility model, it is easier to the behaviour of fixed installation of the steel cable in connector
Make.
Steel cable involved in the utility model is the steel cable of polymer-coated, is applicable in existing any type of polymer and applies
Cover steel cable, such as polymer-coated steel cable described in CN1753826A.
Another purpose according to the present utility model, provide it is a kind of for fixed polymer coating steel cable in lift appliance
In connector, including a wedge-shaped sleeve and a wedge block, there is wedge-shaped sleeve a cavity to be used to receive wedge block and polymerization
One end of the steel cable of object coating, wedge block have side in a thickness direction, and wedge block is at least part of side
It is used to keep the end of the steel cable of polymer-coated equipped with guide groove, which is characterized in that guide groove has width Wg, unit mm, wedge
Shape block has thickness Tw, and the ratio of unit mm, Wg and Tw are between 0.38-0.67.
Compared to existing wedge joint, for keeping the guide groove of steel cable deep on wedge block in the connector of the utility model
Spend it is shallower, in the fixed steel cable of the connector that is applicable in the utility model, so that steel cable and leading on wedge-shaped sleeve inner wall and wedge block
Pressure area between slot becomes larger, this makes the frictional force between steel cable and connector become larger, and steel cable can be fixed more firmly.
And even if the polymer-coated layer of steel cable falls off, since guide groove is shallower, steel cable still can between wedge-shaped sleeve and wedge block
It is firmly fixed, will not fall off because of polymer-coated layer and leads to falling off for steel cable.Therefore elevator rope is safer.
