Detailed description of the invention
Below, be described for implementing embodiments of the present invention with reference to accompanying drawing.
Embodiment 1.
Fig. 1 is the lateral plan of the Riata for elevator that embodiments of the present invention 1 are shown, Fig. 2 is the cutaway view of the Riata for elevator of Fig. 1.In the drawings, the core cord 1 of a steel is had in the center configuration of Riata for elevator.The core cord cladding 2 that resin is made is provided with in the periphery of core cord 1.The core rope rope 3 of many (being eight here) steels is had at the periphery twisted of core cord cladding 2.
The core rope cladding 5 that resin makes is provided with at core cord cladding 2 and the peripheries of core rope rope complexs 4 that are made up of eight core ropes rope 3.Core rope 6 is made up of core cord 1, core cord cladding 2, core rope rope 3 and core rope cladding 5.
The outer straton rope 7 of many (being 20 here) steels is had at the periphery twisted of core rope cladding 5.Rope main body 8 is made up of core rope 6 and outer straton rope 7.The external sheath body 9 that resin is made is provided with in the periphery of rope main body 8.Outer straton rope 7 and external sheath body 9 bonding by sticker.
The all son ropes comprising 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.
Core cord 1 and core rope rope 3 are three-deckers of periphery boundling two deck wire in core wire.And the cross section structure of core cord 1 and core rope rope 3 is western Shandong type (シ mono-Le shape).And the twisted length of two deck wires of core cord 1 and core rope rope 3 is equal.That is, core cord 1 is formed in the mode of parallel twisted with core rope rope 3.Outer straton rope 7 is double-layer structures of periphery boundling one deck wire in core wire.
For the material of core cord cladding 2 and core rope cladding 5, owing to needing the pressure kept from core rope rope 3 or outer straton rope 7, there is because being employed herein such as polyethylene or polypropylene etc. the resin of hardness to a certain degree.And core cord cladding 2 and core rope cladding 5 are made up of the resin be cross-linked by being mixed into crosslinking agent.
And for core cord cladding 2 and core rope cladding 5, in order to improve the elasticity as Riata for elevator, the loss simultaneously in order to produce when being reduced in and bending because of rope sheave, is preferably the cladding that friction coefficient is lower to a certain extent.
Like this, as the material of core cord cladding 2 and core rope cladding 5, harder than the material of external sheath body 9 and the material low to the friction coefficient of same metallic material is preferred.And for core cord cladding 2 and core rope cladding 5, slide because they can produce between core cord 1, core rope rope 3 and outer straton rope 7, therefore, the material of excellent in abrasion resistance is preferred.
Owing to needing to guarantee and towability between rope sheave, therefore, external sheath body 9 by the friction coefficient of rope sheave more than 0.2 and there is the resin of sufficient resistance to abrasion, such as polyurethane forms.And outer straton rope 7 is made up of the resin be cross-linked by being mixed into crosslinking agent.
For core cord cladding 2 and core rope cladding 5, preferably: even if under acting on tensioned state in use, core cord cladding 2 and core rope cladding 5 also enter between adjacent core rope rope 3 as shown in Figure 2, and contact with each other.And for core rope cladding 5 and external sheath body 9, preferably: even if under acting on tensioned state in use, core rope cladding 5 and external sheath body 9 also enter between 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 implemented during fabrication and the location information 32 in rope lengths direction with predetermined spacing.Check result information 31 and location information 32 such as use chopping machine or laser marker etc. to be printed on external sheath body 9.
Inspection during manufacture be external sheath body 9 in Fabrication procedure coated after or implement in the inspection operation of separating with Fabrication procedure.In addition, inspection during manufacture is implemented continuously or every predetermined space along rope lengths direction.
As the content checked, such as, there are by the rope diameter inspection of laser type measuring outside diameter device, by ultrasonic sensor or the coated thickness inspection of eddy current type sensor and the continuity test by magnetic-leakage type rope detector.
The result of each inspection, by the other record explicitly of the position with Mission Number and length direction, indicates the synthetic determination result of all inspections at outer cladding 9.That is, all check results are not abnormal then prints to " OK ", even and if have an exception also to print to " NG ".
In addition, usually, Riata for elevator, after the length manufacturing 2000mm ~ 6000m, cuts into the length of needs according to used lift appliance.When check result information 31 is " NG ", Riata for elevator is avoided this partial cut and carry out finished product.In addition, according to detecting abnormal inspection item or scope, the finished product of Riata for elevator entirety can sometimes also be postponed.
As location information 32, length, factory length the end from (before cut-out) when manufacturing are marked on external sheath body 9.In the example of fig. 1, factory length is indicated every 0.1m.
In addition, check result information 31 and location information 32 are marked on the same position of the circumference of external sheath body 9.That is, check result information 31 and location information 32 are marked on on the straight line of the axis being parallel of Riata for elevator.
In such Riata for elevator, indicate check result information 31 on the surface of outer cladding 9 with predetermined spacing, even if therefore also can the every part of easily visual confirmation check result during fabrication after dispatching from the factory.Therefore, from needless to say before dispatching from the factory, even if after finished product dispatches from the factory, during inspection before delivery and the installation of lift appliance time, also again can check check result from the outward appearance of Riata for elevator.Therefore, even if when comprising the Riata for elevator being detected abnormal part and dispatching from the factory mistakenly because of some reason, also can easily find this Riata for elevator.
In addition, owing to location information 32 and check result information 31 being recorded in the lump, therefore check that data become easy with in kind contrasting.Which in addition, when carrying out maintenance inspection to the Riata for elevator in use, when creating unusual part or need the part continuing to check, can this situation of position this position is in Riata for elevator become numerical value to hold rapidly.In addition, when Riata for elevator is cut to need length, do not need to use special length meter in addition.
In addition, when car stop at pull in position time, which part of pre-recorded Riata for elevator is positioned at the position of the mark being such as located at towing machine, thus, when rescue operation implemented by M/C towing machine, car precision can be made to move to position of pulling in well.
In addition, check result information 31 and location information 32 being marked point-blank, to reduce print pitch to a certain extent, thus, when being hung with car and counterweight, the twisted situation of Riata for elevator can be confirmed.
Here, in order to confirm twisted, within print pitch is preferably two spacing of the twisted spacing of outer straton rope 7.That is, when being formed as far as possible short spacing, lettering becomes continuous print line, is suitable for the confirmation of twisted.But considering the length of lettering, is comparatively difficult within being formed as a spacing as a rule.Contrary, if be formed as more than three spacing, be then difficult to judge that the torsion of lettering is due to the rotation of Riata for elevator or owing to twist or backtwisting causes.
Usually, a spacing of the twisted of outer straton rope 7 is about 6.5 times of the diameter of Riata for elevator.Such as, if the diameter of Riata for elevator is 12mm, then a spacing of twisted is about 70 ~ 80mm, and two spacing 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 external sheath body 9, the friction coefficient between external sheath body 9 and driving rope sheave is large, is difficult to produce Riata for elevator relative to the slip driving rope sheave.Therefore, because wearing and tearing cause the possibility of check result information 31 and location information 32 disappearance lower.But, when hypothesis causes lettering disappearance in use due to running state etc., preferably: use laser marker etc. to deepen the lettering degree of depth of check result information 31 and location information 32.
In addition, in Riata for elevator as described above, owing to use only a core cord 1, therefore when act in use tensioned thus from core rope rope 3 be applied with load to core cord 1 time, rope is difficult to distortion, the cross sectional shape of Riata for elevator entirety can be made to stablize, and the operation of twisted rope can be reduced, manufacture can be made to become easy.In addition, core rope rope 3 is not that directly twisted is in the periphery of core cord 1, but twisted is in the periphery of core cord cladding 2, therefore, it is possible to make the cross sectional shape of core rope 6 be difficult to distortion, the cross sectional shape of Riata for elevator entirety also can be made thus to stablize.
And, do not restrict with other sons due to all son ropes comprising core cord 1, core rope rope 3 and outer straton rope 7 and directly contact, therefore, it is possible to the frictionally damage preventing the factor rope from contacting with each other and cause, thus the long lifetime of Riata for elevator can be realized.
And, draw to make to produce between external sheath body 9 and rope sheave, need external sheath body 9 to be adhered to outer straton rope 7, before external sheath body 9 is bonded to outer straton rope 7, need the foul or the oil content that wait attachment during fabrication of the fully outer straton rope 7 of cleaning.Now, if the complex structure of outer straton rope 7, then fully cannot clean the inside to outer straton rope 7.To this, in embodiment 1, three-decker is formed as owing to making core cord 1 and core rope rope 3, and make outer straton rope 7 be formed as double-layer structure, therefore, can while guaranteeing enough intensity, fully and easily clean outer straton rope 7, thus external sheath body 9 can be adhered to outer straton rope 7 securely.
And, because core cord cladding 2 and core rope cladding 5 are made up of the resin material be cross-linked, therefore, carry out continuously acting on and the temperature that causes rises for use in high temperature environments or because of bending, durability can be improved, realize long lifetime.
And, because external sheath body 9 is also made up of the resin material be cross-linked, therefore, carry out continuously acting on and the temperature that causes rises for use in high temperature environments or because of bending, durability can be improved, realize long lifetime.And, the temperature caused by the skidding between rope sheave during emergency braking and Riata for elevator is risen, can prevent intensity from reducing, thus sufficient deceleration performance can be maintained.
