The specific embodiment
Below, the example of accompanying drawings the best of the present invention.
Example 1
Fig. 1 is the cutaway view of the Riata for elevator of the invention process form 1.In the drawings, Dai Zhuan rope body 1 has 7 root ropes 2, coats son rope 2 and forms incorporate resinous cladding 3.Each son rope 2 has the rope strand 4 of many steels.Rope strand 4 afterturns parallel to each other (with reference to JIS G 3525 12.2b).In all child ropes 2, all rope strands 4 are parallel afterturn.Son rope 2 is (Fig. 1) configuration side by side on the cross section vertical with length direction of rope body 1.That is, 7 root ropes 2 keep at interval and the in-line alignment arrangements along the Width (left and right directions of Fig. 1) of rope body 1 is mutual on the cross section vertical with length direction of rope body 1.
The diameter of rope strand 4 is the about 1/400 best of rope body 1 rope sheave of being reeled (not having diagram) diameter.Like this, can alleviate the flexure stress of rope sheave, fatigue durability is improved.In addition, meticulous for the diameter that does not make rope strand 4, as the cross-sectional configuration of child rope 2, compare a preferably watt spirit with filled type with the sealed type of JIS G 3525 defineds and gulp down (ウ オ リ Application ト Application イ プ) formula.
Such Riata for elevator, because son rope 2 configuration side by side, and,, can prevent that sub-rope 2 from the phase mutual friction taking place simultaneously so can prevent moving of son rope 2 with resinous cladding 3 coatings, thereby, can guarantee stable intensity, realize long lifetime simultaneously.
In addition, be parallel afterturn owing to constitute the rope strand 4 of each son rope 2, so be line contact constraint mutually between the rope strand 4.Like this, rope strand 4 to be in contact with one another pressure little, son rope 2 is difficult for inter deteriorations take place, and thus, can guarantee stable intensity, realizes long lifetime simultaneously.
Especially example 1, because all rope strands 4 of all child ropes 2 are parallel afterturn, so can guarantee that in whole cross section impartial intensity and shape stability are good.
Have, adopt the rope strand 4 and the resinous cladding 3 of rigid polyurethane of steel, son rope 2 is adhered to one another by lining cement 5 with cladding 3, so can guarantee sufficient abrasion resistance, the convergence of banded stability and son rope 2 is improved.
Here, descend in rope body 1 integral intensity, under the situation of lesion development, son rope 2 is according to the big order of load burden or damage serious order and rupture.To this, can make each son rope 2 burden load difficulty that becomes equably if increase the radical of son rope 2 in advance, can not gain in strength pro rata with restrict 2 radical of son.
In addition, forming incorporate Riata for elevator with cladding 3, is to be difficult to detect cladding 3 in-to-in rope strands 4 to be damaged to which kind of degree.Promptly it is generally acknowledged: whether son rope 2 damage of degree of the outside face distortion of cladding 3 has taken place to make, and cuts off fully at least to 1 root rope 2, not so can't judge the replacing period of rope body 1.
To this, be about 80% in order to ensure the remaining intensity of rope body 1 when changing according to the life-span, son rope 2 needs to use more than 5.But,, can predict that the damage of other child rope 2 is also developing and causing strength degradation when the occasion of strength degradation to 2 fractures of 1 root rope.Usually, because the standard disruptive load has surplus, so the remaining intensity ratio standard value when reaching the replacing benchmark of JIS reduces about 5%.
Ask the best radical of son rope 2 from above content.That is, establish to decide remaining intensity be a, change benchmark common remaining intensity down is that the radical of b, son rope is that the disruptive load of N, son rope 2 is P, then formula a * P * N=b * P (N-1) establishment.If a=80%, b=95%, 0.8 * P * N=0.95P (N-1) then, N=6.3 promptly obtains and is about 7.Therefore, use the child rope 2 more than 7 just can guarantee sufficient remaining intensity at least.
In addition, the material of cladding 3 is not limited to the thermoplastic polyurethane resin, can be according to suitably selections such as usage conditions.But at high temperature, when many wet environment use, be that polyurethane is compared, preferably be difficult for taking place the rigid polyurethane of hydrolysis with the ester of easy generation hydrolysis.
Example 2
Fig. 2 is the cutaway view of the Riata for elevator of the invention process form 2.In the drawings, Dai Zhuan rope body 11 has 7 root rope complexs 12, coats son rope complex 12 and forms incorporate resinous cladding 13.Each son rope complex 12 configuration side by side on the cross section vertical of rope body 11 with length direction.That is, 7 root rope complexs 12 keep mutually at interval and in-line is arranged and disposed along the Width of rope body 11 on the cross section vertical with length direction of rope body 11.
Each son rope complex 12 comprises respectively, the resinous core 14 that extends along the length direction of rope body 11, be configured in core 14 around and with 3 root ropes 15 of core 14 afterturns.Each son rope 15 has the rope strand 16 of many steels.Rope strand 16 afterturns parallel to each other.In all child ropes 15, all rope strands 16 are parallel afterturn.
3 root ropes, 15 cross sections of each son rope complex 12 are configured in around the core 14 triangular in shapely.The cross-sectional configurations that son rope complex 12 is configured to son rope 15 is shaped as alternately reverse.
As the material of core 14, the material that can use for example the syntheticfibres high density afterturn with the thermoplastic base resin of acrylic resin, poly-vinyl resin or ethene etc. or high-intensity aramid fibre or mekralon etc. to form.
The peripheral part at least of each son rope 15 for the integrated and adhesive-applying 5 of cladding 13.Promptly son rope 15 is adhered to one another by lining cement 5 with cladding 13.
Such Riata for elevator, complex 12 disposes side by side because son is restricted, and coats with resinous cladding 13, so can prevent moving of son rope complex 12, can prevent that son rope complex 12 from the phase mutual friction taking place simultaneously, thereby, can guarantee stable intensity, realize long lifetime simultaneously.
In addition, be parallel afterturn owing to constitute the rope strand 16 of each son rope 15, so son rope 15 is difficult for inter deterioration takes place, thus, can guarantee stable intensity, realize long lifetime simultaneously.
In addition, owing to constitute son rope complex 12,, can dwindle suitable rope sheave diameter so can use thinner rope strand 16 with core 14 and 3 root ropes 15.
Have, 3 root ropes, 15 cross sections are configured in around the core 14 triangular in shapely again.The cross-sectional configurations that sub-rope complex 12 is configured to son rope 15 is shaped as alternately reverse, so complex 12 arranged in high density of son can being restricted can make the width of rope body 11 diminish, improves intensity simultaneously, can also dwindle the width that is suitable for rope sheave
