Description
[technical field]
The Riata for elevator for suspension craning cab that the present invention relates to use in elevator and lift appliance.
[background technology]
Lift appliance has following formation conventionally: rope is suspended on the rope sheave being installed in elevator motor, in one end of rope, hangs and be provided with car, at the other end of rope, hang and be provided with for keeping the bob-weight (Hammer of balance with car).In thering is the lift appliance of such formation, in the past, (the rope footpath hereinafter referred to as in order to prevent premature wear or the fracture of rope, used to there is rope diameter.) rope sheave of 40 times of above diameters.The diameter of this rope sheave (rope sheave footpath hereinafter referred to as.) directly related with the driving torque of the required motor of car lifting, thereby make to take the various parts of the lift appliance that motor is representative to realize miniaturization, lightweight by reducing rope sheave footpath.Wherein, in order to reduce rope sheave footpath, for the above reasons, rope footpath also must reduce.
But while reducing rope footpath not changing the radical of rope, the intensity of rope can reduce, the maximum rated load (Plot Load of elevator possibility weight) can reduce.In addition, if increase the radical of rope, the structure of lift appliance can become complicated.In addition, if reduce rope sheave footpath, the flex life of rope shortens, and needs the frequent rope of changing.
As the means that address these problems, there is document to propose following Riata for elevator: many steel wire twisteds are made to strand, many twisteds of this strand are made to rope, with the most peripheral (for example,, referring to patent documentation 1) of coated this rope of resin material.The lift appliance that has used such Riata for elevator is by the resin material of coated rope most peripheral and the friction force between rope sheave and driven, therefore wishes improve the frictional behavior of resin material and make its stabilization.
Method as improving the frictional behavior between rope sheave and rope, has document to propose to utilize the not polyurethane clad material of the content of wax to carry out coated Riata for elevator (for example,, referring to patent documentation 2) to rope.
Incidentally, the friction coefficient of known resin material depends on sliding velocity and temperature conventionally to a great extent.Also the viscoelastic properties such as dynamic viscoelastic of known resin material have correlativity (Williams-Landel-Ferry formula (WLF formula)) between sliding velocity and temperature in addition.Particularly, the in the situation that of rubber, between viscoelastic property and sliding velocity and temperature, also there is same correlativity, thereby show the viscoelastic property of rubber relevant with the frictional behavior of rubber (for example,, referring to non-patent literature 1).

In various TPUEs, for the 1st resinous principle, aspect the hydrolysis that prevents from producing environment for use, consider, be preferably the TPUE beyond polyester system; For example, if consider desired various characteristics in Riata for elevator (flexibility, durability, resistance to cold), more preferably JIS A hardness (hardness of utilizing A type hardness tester instrumentation to obtain of JIS K7215 defined) is the more than 85 polyethers based thermoplastic polyurethane elastomer below 95.
The 2nd contained resinous principle of resin combination that forms resin-coating layer 2 is that glass transition temperature is than high 20 ℃ of above or low 20 ℃ of above resinous principles of the glass transition temperature of the 1st resinous principle.
As the 2nd resinous principle with such characteristic, as long as meeting above-mentioned condition is just not particularly limited, from the aspect of durability, abrasion test, be preferably the TPUE or the amilan that use the polyalcohol different from the TPUE of the 1st resinous principle to form for raw material.And, in various TPUEs, for the 2nd resinous principle, for example, if consider desired various characteristics in Riata for elevator (flexibility, durability, resistance to cold), preferably JIS A hardness (hardness of utilizing A type hardness tester instrumentation to obtain of JIS K7215 defined) is the more than 85 polycarbonate-based thermoplastic polyurethane elastomer below 95 or silicone-based TPUE.
As amilan, can enumerate Thermoplastic polyamide elastomer, polyamide-based thermoplastic base resin etc.
So-called Thermoplastic polyamide elastomer refers to conventionally by hard section of the polyamide soft section of material that forms, at room temperature demonstrates caoutchouc elasticity with polyethers or polyester.Wherein, from the aspect of hydrolytic resistance, preferably by hard section of the polyamide soft section of Thermoplastic polyamide elastomer forming with polyethers.
Polyamide-based thermoplastic base resin typically refers to the thermoplastic base resin in strand with polyamide bond, can enumerate nylon 6, nylon 66, nylon 11, nylon 12 etc. as example.These materials may be used singly or in combination of two or more.
The mass ratio of the 1st resinous principle and the 2nd resinous principle is 90: 10～70: 30.If the mass ratio of the 2nd resinous principle is too low, can not get the effect (the particularly stable friction coefficient in resin-coating layer 2) obtaining by mixing the 2nd resinous principle.Otherwise if the mass ratio of the 2nd resinous principle is too high, the characteristic of the 2nd resinous principle is preponderated, the resin-coating layer 2 consisting of the formed body of resin combination is really up to the mark, and the flexibility durability impaired or resin-coating layer 2 of rope reduces.Its result, if drive the lift appliance that uses this rope, there will be the problems such as durability variation while making power consumption increase or alternating bending.
The resin combination that forms resin-coating layer 2 can be by mixing to prepare to mentioned component by known means.For this resin combination, can according to the mode that covers the periphery of rope main body 1, carry out moulding by using the known moulding means such as extrusion molding, injection moulding, make thus resin-coating layer 2.And, for the physical property of the article shaped of resin combination is stablized, can implement furnace run.The condition of furnace run can be carried out suitable adjustment according to used resin combination, is not particularly limited.
The glass transition temperature of resin-coating layer 2 is higher, and the sliding velocity dependence of friction coefficient is less, and the modulus of elasticity of resin-coating layer 2 also tends to increase in addition.Therefore, in the situation that by the rope that is formed with the resin-coating layer 2 that glass transition temperature is high for lift appliance, the flexibility of rope is tended to impaired, or while making rope repeatedly carry out bending, there is the tendency of the endurance failures such as breaking of resin-coating layer 2 due to easy generation stress under the environment of the glass transition temperature higher than resin-coating layer 2.Therefore, for the loss modulus E by viscoelastic spectra " the glass transition temperature of resin-coating layer 2 of peak temperature defined, in the situation that only there is 1 above-mentioned peak, this temperature be preferably-20 ℃ following, below more preferably-25 ℃.In addition, in the situation that above-mentioned peak temperature has 2, below the glass transition temperature of the 1st resinous principle that resin-coating layer 2 is contained is preferably-20 ℃, below more preferably-25 ℃.
In addition,, if be greater than 98, the flexibility of rope is easily damaged for the JIS A hardness of resin-coating layer 2 (hardness of utilizing A type hardness tester instrumentation to obtain of JIS K7215 defined), and while driving the lift appliance that uses this rope, power consumption tends to increase.Otherwise if the JIS A hardness of resin-coating layer 2 is less than 85, the durability during as Riata for elevator alternating bending has the tendency of variation.Therefore, the JIS A hardness of resin-coating layer 2 is preferably more than 85 below 98.
In Riata for elevator, from the viewpoint of improving the adaptation of resin-coating layer 2 pairs of rope main body 1, can in rope main body 1, be coated with cement in advance, then form resin-coating layer 2.As cement, as long as for metal and polyurethane are just not particularly limited with cement, can enumerate for example Chemlok (registered trade mark (RTM)) 218 (LORD FarEast Incorp Ltd manufacture).
Have in the Riata for elevator of above-mentioned feature, because relying on the resin material that temperature or sliding velocity have stable friction coefficient, utilization is not coated rope, thereby for lift appliance in the situation that, under the sliding velocity on a large scale of the sliding velocity when maintaining the required small sliding velocity region of car quiescence to common running, can make the stable braking of car.

1), near the connecting part of Riata for elevator 10 and bob-weight 12, force transducer 14 is set.Similarly, in order to measure the rope tension (T of ground 13 sides
2), near the connecting part on Riata for elevator 10 and ground 13, force transducer 14 is set.
In this system, if with specified speed clickwise rope sheave 11, the rope tension (T of ground 13 sides
2) corresponding reduction, reduction value is corresponding to the friction force producing between Riata for elevator 10 and rope sheave 11, at the rope tension (T of bob-weight 12 sides
1) between produce Tension Difference.Utilize 14 pairs of force transducers rope tension (T now
1and T
2) measure, be brought in following general formula, thereby obtain the friction coefficient between Riata for elevator 10 and rope sheave 11.In addition, at rope tension (T
1and T
2) mensuration in, the situation of small sliding velocity is defined as to 1 * 10
-5mm/second, the situation of the sliding velocity that conventionally turns round is defined as to 0.01 mm/second and 1 mm/second, with these speed, rope sheave 11 dextrorotations is transferred and implement to measure.And temperature during this mensuration is 25 ℃.
[several 1]
In above-mentioned formula, θ is rope winding angle (i.e. 180 degree), K
2the coefficient determining for shape by rope sheave groove (1.19).
For the result of the friction coefficient being obtained by above-mentioned formula, by sliding velocity, be that the friction coefficient in the situation of 1 mm/second is made as 100, the relative value of take with respect to this friction coefficient represents that by sliding velocity be 0.01 mm/second and 1 * 10
-5friction coefficient in the situation of mm/second, the results are shown in table 1.
[table 1]
The friction coefficient of the Riata for elevator obtaining in embodiment and comparative example as shown in Table 1, demonstrates along with sliding velocity reduces and the tendency that reduces.But the change of the friction coefficient of the Riata for elevator obtaining in embodiment is little, sliding velocity 1 * 10
-5friction coefficient in the situation of mm/second can maintain the more than 75% of friction coefficient in the situation of 1 mm/second.On the other hand, the change of the friction coefficient of the Riata for elevator obtaining in comparative example is large, sliding velocity 1 * 10
-5friction coefficient in the situation of mm/second is reduced to below 45% of friction coefficient in the situation of 1 mm/second.
And from the result of embodiment 1～3 and comparative example 5, the change of the higher friction coefficient of ratio of polycarbonate-based thermoplastic polyurethane elastomer is less; But if polycarbonate-based thermoplastic polyurethane elastomer is too high with respect to the mass ratio of polyethers based thermoplastic polyurethane elastomer, the resin-coated layer of Riata for elevator can become really up to the mark, can not get having can be used as the product that rope carries out the flexibility of alternating bending.
From above result, according to the present invention, by utilization, there is the temperature of not relying on or sliding velocity and the resin material of stable friction coefficient is coated rope, Riata for elevator and the lift appliance that under a kind of sliding velocity on a large scale of the sliding velocity when maintaining the required small sliding velocity region of car quiescence to running conventionally, can make the stable braking of car can be provided.
