The specific embodiment
Below, describe being used for implementing embodiments of the present invention with reference to accompanying drawing.
Fig. 1 is the lateral plan that the Riata for elevator of embodiments of the present invention 1 is shown, and Fig. 2 is the cutaway view of the Riata for elevator of Fig. 1.The core cord 1 that a steel is arranged in the center configuration of Riata for elevator in the drawings.Periphery at core cord 1 is provided with the core cord cladding 2 that resin is made.The core rope rope 3 that many (being eight here) steels are arranged at the periphery twisted of core cord cladding 2.
Be provided with the core rope cladding 5 that resin is made at core cord cladding 2 with by the sub periphery of restricting complex 4 of core rope that eight core rope ropes 3 consist of.Core rope 6 is made of core cord 1, core cord cladding 2, core rope rope 3 and core rope cladding 5.
The outer straton rope 7 that many (being 20 here) steels are arranged at the periphery twisted of core rope cladding 5.Rope main body 8 is made of core rope 6 and outer straton rope 7.Periphery in rope main body 8 is provided with the outer cladding 9 that resin is made.Outer straton rope 7 and outer cladding 9 are bonding by sticker.
All son ropes that comprise core cord 1, core rope rope 3 and outer straton rope 7 are compressed (plastic working) by mould from periphery during fabrication, and the cross sectional shape of these wire rods produces distortion.
For the material of core cord cladding 2 and core rope cladding 5, owing to needing maintenance from the pressure of core rope rope 3 or outer straton rope 7, therefore used the resin that has hardness to a certain degree such as polyethylene or polypropylene etc.And core cord cladding 2 and core rope cladding 5 are by having carried out crosslinked resin and consist of by sneaking into crosslinking agent.
And, for core cord cladding 2 and core rope cladding 5, in order to improve the elasticity as Riata for elevator, simultaneously in order to be reduced in the loss that produces when crooked because of rope sheave, be preferably to a certain extent lower cladding of friction coefficient.
Like this, as the material of core cord cladding 2 and core rope cladding 5, harder and be preferred to the low material of the friction coefficient of same metallic material than the material of outer cladding 9.And, for core cord cladding 2 and core rope cladding 5 and since their can and core cord 1, core rope rope 3 and outer straton rope 7 between produce slip, therefore, the material of excellent in abrasion resistance is preferred.
Because need to guarantee and rope sheave between towability, therefore, outer cladding 9 by to the friction coefficient of rope sheave more than 0.2 and resin, for example polyurethane with sufficient resistance to abrasion consist of.And outer straton rope 7 is by having carried out crosslinked resin and consist of by sneaking into crosslinking agent.
For core cord cladding 2 and core rope cladding 5, preferably: even effect has under the state of tension force in use, core cord cladding 2 and core rope cladding 5 also enter between the adjacent core rope rope 3 as shown in Figure 2, and contact with each other.And for core rope cladding 5 and outer cladding 9, preferably: even effect has under the state of tension force in use, core rope cladding 5 and outer cladding 9 also enter between the adjacent outer straton rope 7 as shown in Figure 2, and contact with each other.
On the surface of outer cladding 9, indicate the check result information 31 corresponding with its position of the inspection of implementing during fabrication and the location information 32 of rope lengths direction with predetermined spacing.Check result information 31 and location information 32 are such as using chopping machine or laser-marking device etc. to be printed on the outer cladding 9.
Inspection during manufacturing is to implement after the coating of the outer cladding 9 in Fabrication procedure or in the inspection operation of separating with Fabrication procedure.In addition, the inspection during manufacturing is implemented continuously or every predetermined space ground along the rope lengths direction.
As the content that checks, for example enumerate rope diameter inspection by laser type measuring outside diameter device, check and by the continuity test of magnetic-leakage type rope detector by the coating thickness of ultrasonic sensor or eddy current type sensor.
Each result who checks by with the position of Mission Number and length direction other record explicitly, indicate the synthetic determination result of all inspections at outer cladding 9.That is, all check results unusually then do not print to " OK ", even and if have one unusually to print to " NG " yet.
In addition, usually, Riata for elevator cuts into the length of needs according to employed lift appliance after manufacturing the length of 2000mm～6000m.In the situation that check result information 31 is " NG ", Riata for elevator is avoided this part cut off finished products.In addition, according to detecting unusual inspection item or scope, sometimes also can postpone the finished products of Riata for elevator integral body.
As location information 32, will be when making length, factory length the end of (before cutting off) be marked on the outer cladding 9.In the example of Fig. 1, indicate factory length every 0.1m.
In addition, check result information 31 and location information 32 are marked on the circumferential same position of outer cladding 9.That is, check result information 31 is marked on the straight line parallel with the axis of Riata for elevator with location information 32.
In such Riata for elevator, indicate check result information 31 on the surface of outer cladding 9 with predetermined spacing, even the therefore also every part of Visual Confirmation check result during fabrication easily after dispatching from the factory.Therefore, before dispatching from the factory, from needless to say, even after finished product dispatches from the factory, during inspection before delivery and during the installation of lift appliance, also can again check check result from the outward appearance of Riata for elevator.Therefore, even comprising in the situation that the Riata for elevator that is detected unusual part is former because of some thereby dispatch from the factory mistakenly, also can easily find this Riata for elevator.
In addition, because location information 32 and check result information 31 are put down in writing in the lump, check that therefore data and the contrast of material object become easy.In addition, when the Riata for elevator in using is carried out maintenance inspection, maybe need in the situation of the part that continues to check having produced the unusual part, this situation of which position in the Riata for elevator of can rapidly this position being in becomes numerical value and holds.In addition, need length in the situation that Riata for elevator is cut to, do not need to use in addition special length meter.
In addition, when car stops at when pulling in the position, which of pre-recorded Riata for elevator partly is positioned at the position of the mark of for example being located at towing machine, thus, when the M/C towing machine is implemented the rescue operation, can make the car precision move to well the position of pulling in.
In addition, check result information 31 and location information 32 are marked on the straight line, to reduce to a certain extent print pitch, thus, when being hung with car and counterweight, can confirm the twisted situation of Riata for elevator.
Here, in order to confirm twisted, print pitch is preferably in two spacings of twisted spacing of outer straton rope 7.That is, when forming the spacing of trying one's best short, lettering becomes continuous line, is suitable for the affirmation of twisted.But, consider the length of lettering, form as a rule a spacing with interior be difficulty comparatively.Opposite, if form three more than the spacing, then be difficult to judge reversing because the rotation of Riata for elevator or owing to twisting or backtwisting cause of lettering.
Usually, about 6.5 times of the twisted of outer straton rope 7 spacing diameter that is Riata for elevator.For example, if the diameter of Riata for elevator is 12mm, then twisted spacing is about 70～80mm, and two spacings of twisted are about 140～160mm.Therefore, the print pitch 100mm shown in Fig. 1 can say in suitable scope.
In addition, in the Riata for elevator with outer cladding 9, outer cladding 9 and the friction coefficient that drives between the rope sheave are large, are difficult to produce Riata for elevator with respect to the slip that drives rope sheave.Therefore, because the possibility that wearing and tearing cause check result information 31 and location information 32 to disappear is lower.But lettering disappears in the situation that hypothesis is because running state etc. causes in use, preferably: the lettering degree of depth of deepening check result information 31 and location information 32 with laser-marking device etc.
In addition, in Riata for elevator as described above, owing to only having adopted a core cord 1, therefore thereby when having acted in use tension force and be applied with load from core rope rope 3 to core cord 1, rope is difficult to distortion, can make the cross sectional shape of Riata for elevator integral body stable, and can reduce the operation of twisted rope, can make to make to become easy.In addition, core rope rope 3 is not that directly twisted is in the periphery of core cord 1, but therefore twisted can make the cross sectional shape of core rope 6 be difficult to distortion in the periphery of core cord cladding 2, also can make thus the cross sectional shape of Riata for elevator integral body stable.
And, do not restrict with other sons and directly do not contact owing to comprising all son ropes of core cord 1, core rope rope 3 and outer straton rope 7, therefore, can prevent that the factor rope from contacting with each other and the frictionally damage that causes, thereby can realize the long lifetime of Riata for elevator.
And, produce traction between outer cladding 9 and the rope sheave in order to make, outer cladding 9 need to be adhered to outer straton rope 7, before outer cladding 9 was bonded to outer straton rope 7, what need fully to clean outer straton rope 7 waited foul or the oil content that adheres to during fabrication.At this moment, if the complex structure of outer straton rope 7 then can't fully clean to the inside of outer straton rope 7.To this, in embodiment 1, owing to making core cord 1 and core rope rope 3 form three-decker, and make outer straton rope 7 form double-layer structure, therefore, can when guarantee enough intensity, fully and easily clean outer straton rope 7, thereby outer cladding 9 can be adhered to outer straton rope 7 securely.
And, because core cord cladding 2 and core rope cladding 5 are made of crosslinked resin material, therefore, rise for the use under hot environment or because bending acts on the temperature that causes continuously, can improve durability, realize long lifetime.
And, because outer cladding 9 also is made of crosslinked resin material, therefore, rise for the use under hot environment or because bending acts on the temperature that causes continuously, can improve durability, realize long lifetime.And, between the rope sheave for by emergency braking time the and the Riata for elevator skid and the temperature that causes rises, can prevent strength decreased, thereby can keep sufficient deceleration performance.

In addition, manufacturing information 33 is printed with the spacing identical with check result information 31 and location information 32 in the rope lengths direction.In addition, manufacturing information 33 circumferentially staggering to the position different from check result information 31 and location information 32 and be printed at outer cladding 9.Other structure is the same with embodiment 1.
In such Riata for elevator, owing to indicating manufacturing information 33 with predetermined spacing at outer cladding 9 along the rope lengths direction, therefore other data plate need not be set, just can be by its Visual Confirmation in kind information relevant with manufacturing.
In addition, the cross section structure of Riata for elevator of the present invention is not limited to the structure of Fig. 2.For example, also can be the structure of core cord 1 not being implemented distortion processing; The structure that the number of core rope rope 3 and outer straton rope 7 reduces respectively (for example core rope rope is 6, and outer straton rope is 16); And the double-layer structure etc. that has omitted core rope rope 3 and core rope cladding 5.
In addition, the cross section has been shown in embodiment 1,2 has been circular Riata for elevator, but said Riata for elevator is broad sense in the present invention, comprises that also cross sectional shape is flat rope, be i.e. rope band.
In addition, in embodiment 1,2, the synthesis result of all inspections is marked on the outer cladding 9 as check result information 31, but check result information 31 also can be in order to understand each result's who checks information.In the case, if come encode ground expression check result by the arrangement that predetermines, then can represent compactly check result information 31.For example, if can with not unusually then as " 0 " if the result who unusually then represents above-mentioned rope diameter inspection, coating thickness inspection and continuity test as three bit digital of " 1 " is arranged.In addition, also can represent unusual having or not with the arrangement of " zero " or marks such as " * ".
