To this end, a rope is used in which a plurality of element wires constituting the wire rope are each covered with resin material and the whole wire rope is covered with resin material, thereby reducing the wear due to slippage between the element wires and the wear due to contact with the sheave, which wear occurs when the rope is entrained around the sheave. When the elevator sheave diameter is reduced, a worried lowering of the rope life can be suppressed or the rope life can be improved. Thus, it is possible to achieve reduction of size and weight of equipment including motors and hoists, installation space saving for elevators, improved safety and reliability of the system by virtue of the increased rope life.
Description
Technical field
The present invention relates to a kind of cable type elevator, particularly, the present invention relates to a kind of elevator that adopts cable wire, and cable wire is made by the steel wire that is coated with resin material, and the excircle of cable wire also is coated with resin material.
Background technology
The cable type elevator comprises that one is provided with the drive unit of a motor, a decelerator, a pulley and a deflecting wheel, elevator railway carriage load is applied to that main rope one end (being referred to as " cable " hereinafter) that is wound on the pulley is gone up and counterweight load is applied to mechanism on the cable other end but also have one, to move up and down elevator railway carriage and counterweight by the frictional force between cable and the pulley.
Cable generally by with a plurality of steel strand wires twists to forming together, and steel strand wires by with the steel wire coil buckling to making together.This cable wire satisfies required frictional behavior, the ABRASION RESISTANCE of driving elevator, fatigue resistance etc., and have very high stability.
But,, therefore must have certain service life because cable is the product of loss-type.The factors of limit life of cable can be divided into four types, that is: when cable when pulley moves past, by the bending of cable and elongation and the fatigue that produces, because the wearing and tearing of the caused by relative motion between the steel wire, be arranged at the wearing and tearing between the wall of outermost steel wire of cable wire and pulley groove, contact with air and the corrosion that produces by cable.Like this, for reducing the influence that cable produces owing to alternating bending when mobile from pulley, the ratio D/d of diameter of pulley D and cable diameters d is set at 40 or bigger.
In addition, the diameter D of the pulley motor-driven moment of torsion required with moving up and down the elevator railway carriage is directly related.For minimizing includes the volume and weight of the elevator of motor, must reduce the diameter of pulley.
In addition, cable wire is wound onto by being activated on the castiron pulley and by friction.Therefore, in the time of in cable is clamped in pulley, being in contact with one another of metalwork shakes generation and noise, thereby influences comfortableness.
As the scheme that addresses these problems, the specification of Japan Patent JP-A-7-267534 discloses and has a kind ofly reduced diameter of pulley and a kind ofly reduce the vibrations and the method for noise by synthetic fiber cable twisted together by using, fiber wherein for example can be an aramid fibre, these fibers have more flexibility than steel wire, but also be coated with resin, urethanes for example.
In addition, be the service life of the synthetic fiber cable of determining to be coated with resin, disclose a kind of conductive carbon fibre the embedding in the synthetic fiber cable that is coated with resin and by detecting voltage in the specification of Japan Patent JP-A-8-261972 and judged the method whether conductive carbon fibre ruptures, wherein the intensity of conductive carbon fibre is weaker than the intensity of synthetic fiber.
In addition, with pulley to contact pressure big more, the service life of cable is also just short more so.In other words, the contact pressure of cable is directly proportional with the tension force F of cable, is inversely proportional to the diameter D of pulley.Like this, if reduce the diameter of pulley, pressure will increase (pressure of cable approximates F/ (D/d)) so.
As the scheme that addresses this problem, International Application No. WO 99/43885 discloses a kind of flat belt that uses and has reduced the method that contacts pressure with pulley, be coated in the life-span of the lip-deep resin of flat belt with prolongation, wherein flat belt is made of a plurality of steel strand wires of arranging along a straight line, and steel strand wires be steel wire by can application of resin or synthetic resin for example aramid fibre be twisted to together and form.
For the mechanical device that reduce to adopt cable comprises diameter of pulley in the cable type elevator, for the volume of the motor that reduces to be used for drive pulley or winch and reduce the erection space of mechanical device, solve the cable life-span that in the process that reduces the cable bending radius, produced and the decline problem of intensity with regard to needs.
One object of the present invention is to provide a kind of safe and reliable cable by solve the cable life-span produced and the reduction problem of intensity when reducing the cable bending radius.
Another object of the present invention is to provides a kind of safe and reliable elevator by solve the cable life-span produced and the reduction problem of intensity when reducing the cable bending radius.

Implement best mode of the present invention
Below with reference to accompanying drawings the present invention is made detailed description.
Cable wire as load bearing component is to make together by the steel wire coil buckling is formed steel strand wires, then steel strand wires are screwed in together.Therefore cable can be widely applied in the pulley in a lot of mechanical devices that comprise elevator by reeling or being clamped in owing to have flexibility.The cable of being made by steel is a kind of loss-type parts, so the prolongation in its service life is decided by the raising of reliability and security.As mentioned above, for reduce cable on pulley when mobile because that alternating bending produces is tired and wear and tear, alternating bending just becomes the cable wire factor in service life that influences, difference according to mechanical device, the diameter D of pulley and the ratio (D/d) between the cable diameters d can be set to a definite value or bigger (for elevator, this value is set to 40 or bigger).
Reduce volume, space and cost that diameter of pulley helps to reduce mechanical device.For making the negative effect minimum of above-mentioned four factors relevant with the cable life-span, cable of the present invention is processed to the structure shown in the following embodiment:
With reference to Fig. 1, as the cable wire 1 of load bearing component be by with steel wire 2 coil bucklings to forming steel strand wires 3 together, then steel strand wires 3 are twisted to and make together.Every steel wire 2 all is coated with a wire coating 4, and whole cable 1 is coated with an inter coat material 6, and its outermost layer is coated with cable coating 5.
Reducing under the situation of diameter of pulley, or in elevator, for the ratio D/d that makes diameter of pulley D and cable diameters d less than 40 (conventional value in the factors of limit life of referring in the prior art), must improve the fatigue properties that cable 1 is produced by its sweep when mobile on pulley.Therefore, should be primarily focused on the bending stress that acts on the steel wire 2 that constitutes cable 1, and test reducing the required wire shape of diameter of pulley.When the cable tier that is used as operation was on pulley, bending stress σ b will act on the steel wire 2.Here, maximum bending stress (σ bmax) acts on the outermost layer of every steel wire along cross section, and the distance of the heart is directly proportional among stress value and the relative steel wire 2.In other words, this numerical value is directly proportional with the diameter δ of steel wire 2.When representing the longitudinal modulus of elasticity of steel wire 2 with E, maximum stress in bend δ bmax can be represented by following equation:
σbmax＝Eδ/D
In addition, stress intensity (amplitude) the σ a that acts on the outermost layer of steel wire 2 can be expressed from the next:
σa＝Eδ/2D
According to these equatioies, just can reduce the possible stress that acts on the steel wire 2 by the diameter δ that reduces steel wire 2.Traditional elevator employing diameter is that pulley and the steel wire diameter of 500mm is the cable wire of 0.8mm.Therefore, as an example, can adopt the cable wire that phosphorus content is 0.7%, diameter is 0.3mm to finish fatigue experiment and determine fatigue limit σ a1 by the tension force of part pulsation.The mean stress of this moment is about 500Mpa.The result as shown in Figure 2.Therefore, can clearly find: the stress intensity of fatigue limit σ a1 (amplitude) σ a is about 260Mpa.
Therefore, if make cable wire with the above-mentioned steel wire of making fatigue experiment, and reduce the diameter of pulley, must satisfy following equation so, purpose is that the ratio D/d between diameter of pulley D and the rope diameter d is set at 40 or littler, and this equation is as follows:
Eδ/2D＜260(Mpa)
For example, in using the lift appliance of traditional steel wire, diameter of pulley D is 500mm, and rope diameter d is 12mm, and its diameter of steel wire that constitutes cable wire 1 is 0.8mm.The ratio D/d of diameter of pulley D and steel wire diameter d is 41.7.Otherwise for the cable wire of present embodiment, if diameter of pulley D is reduced to 200mm, rope diameter d is set at 12mm, and its diameter of the steel wire δ that constitutes cable wire 1 is about 0.50mm, and numerical value D/d is 16.7mm just so.In addition, if steel wire diameter d is set to 12mm, its diameter of the cable wire δ that constitutes cable wire 1 is about 0.25mm, and numerical value D/d is exactly 8.3mm so.
Consider from the angle of fatigue, can reduce the stress σ a that results from the steel wire 2 by the diameter δ that reduces steel wire 2.In addition, if consider that because this factor in caused by relative motion effect of attrition cable wire service life of steel wire 2, the diameter that reduces steel wire 2 so just influences the life-span of cable.The relative motion of cable wire 2, promptly sliding distance increases with the increase of rope diameter d.For reducing the distance of relative motion, the diameter of cable wire is diminished.But the diameter d that reduces cable wire also can reduce the breaking strength of cable wire 1, therefore must improve the breaking strength of steel wire 2.Like this, steel wire 2 its breaking strengths of formation cable wire 1 should be 1770MPa or bigger.
In addition, in the present embodiment, the surface of every steel wire 2 all is coated with wire coating 4, and purpose is to reduce because the wearing and tearing of the caused by relative motion of steel wire 2.Wire coating 4 is made of resin, for example polyethylene, polyamide, tetrafluoroethylene, polyurethane, epoxy resin or vinyl chloride.Compare with steel, the elastic modelling quantity of wire coating 4 is less, thereby when steel wire 2 is in contact with one another, forms enough contacts area, to allow steel wire in the lower situation lower slider of surface pressing.Like this, just can prevent the contact that steel wire 2 is concentrated mutually in the part, thereby reduce the wearing and tearing of steel wire.
The wire coating 4 that is used to reduce steel wire 2 wearing and tearing is made by the current material that the plastic flow dynamic pressure is lower than steel, i.e. the soft coating material.The frictional force that is produced by the mutual sliding-contact of steel wire 2 can be represented by the product Aws of the shear strength s of contact area Aw and material substantially.Like this, contact area Aw equals (vertical load)/(the plastic flow dynamic pressure of material) substantially, thereby makes the steel as base material have less contact area.Therefore, the shearing that is produced by the relative slip of steel wire 2 just can be born by wire coating 4, and wire coating 4 is to be made by the lower soft coating material of shear strength, and vertical load supports by the steel wire 2 as base material, so just makes frictional force very little.In this case, can for example molybdenum sulfide or graphite and can produce identical effect as the soft coating material that constitutes wire coating 4 with kollag.
Under the situation of diameter δ that reduces steel wire 2 and diameter of pulley D, except the wearing and tearing that produce by the relative slip of steel wire 2, also must consider by the most external steel wire on the cable wire and the contact between the pulley groove and the wearing and tearing that produce.Therefore, in the present embodiment, for reducing the wearing and tearing between steel wire 2 and the pulley groove, the outermost surface of cable wire 1 is coated with cable wire coating 5, as shown in Figure 1.The coating material of above-mentioned cable wire 2 can be used as the material of cable wire coating 5.In a word, the ratio of wearing and tearing and pressure of contact surface and material yield pressure has relation closely, therefore can be by reducing this ratio amount of reducing wear.In other words, as mentioned above, it is very effective to the amount of reducing wear to reduce pressure of contact surface.Compare with the situation that steel wire 2 and pulley groove directly contact, whole cable wire 1 is coated with coating with closed state and situation about contacting with pulley groove can increase radius of curvature on contact point, thereby increases contact surface, promptly reduces pressure of contact surface.In addition, the radius of curvature on contact point, can also increase contact area by the elastic modelling quantity that reduces material and contact pressure with reducing.
Because cable 1 of the present invention is made in a manner described, so steel wire 2 can directly not be in contact with one another or directly contact with pulley groove.Like this, by in the steel strand wires 3 with many steel wire formation twisted together, be arranged in outermost steel wire and needn't have ABRASION RESISTANCE.Constitute by Wa Shi (Wallington) shaped steel twisted wire 3 at last according to cable wire 1 of the present invention, and steel wire 2 has the diameter δ that equates substantially.
When and when reducing the diameter D of pulley for the size that helps reducing machinery and weight, make except diminishing bending stress reduces owing to the coating 4 on steel wire, the steel wire 2 and cable wire coating 5 diameters on the whole cable wire 1, the twisting method of cable wire 1 also can influence the pliability of cable wire, and its floating coat 4 is used to reduce the wearing and tearing that produce along with reducing of steel wire diameter.In a word, the twisting method that is used for the steel wire 1 of machinery comprises: make steel wire 2 and steel strand wires 3 twist method (Lang ' s layer) and make steel wire 2 and the steel strand wires 3 common method of twisting of twisting in opposite direction along the Lang Shi of identical direction twisting.
In the cable of making by the Lang Shi method of twisting, the angle that the central axial line of steel wire 2 relative cable wires 1 forms is greater than the corresponding angle of the cable of making by the common method of twisting.Therefore, only with regard to crooked, the overall flexibility that Lang Shi twists cable is very high.Like this, under the cable 1 of present embodiment is used for situation that diameter of pulley diminishes, for example be used for elevator, the ratio that is used for diameter of pulley D and cable diameters d when cable is lower than for 40 following time of situation, can adopt the cable of being made by the Lang Shi method of twisting 1.In addition, in the cable of being made by the Lang Shi method of twisting, it is longer to be positioned at the lip-deep steel wire of cable, and compares with the cable of being made by the common method of twisting, this surface is more level and smooth, contacts and lower pressure of contact surface with regard to the part that the cable of being made by the Lang Shi method of twisting is born seldom like this.Therefore, compare with the cable of being made by the common method of twisting, when cable 1 was clamped in the pulley, the compression that acts on the cable coating was lower.Contact pressure between cable 1 and the pulley increases along with reducing of diameter of pulley.Consider the fatigue and the life-span of cable coating 5, under the cable 1 with present embodiment is applied to situation on the elevator that diameter of pulley diminished, when the ratio D/d of diameter of pulley D and cable diameters d less than 40 the time, just can adopt the cable of making by the Lang Shi method of twisting 1.
In addition, for the cable of making by the common method of twisting, when tension force acts on the cable, increase along separating the rotary resistance of turning round direction.Like this, if the cable of present embodiment 1 is applied on the machinery, and the highest top-priority ability that this machinery is had prevent cable 1 from rotating, so just can adopt the cable of making by the common method of twisting 1.
When steel wire 2 fractures that constitute cable 1, as reducing in service life of the cable 1 of load bearing component.Determine that the crack conditions that outermost layer is coated with the cable 1 of cable coating 5 can be undertaken by following method: utilize magnetic crack detection for example magnetic leakage flux detect the fracture of the steel wire 2 that constitutes load bearing component.
Fig. 3 is the cutaway view that is clamped in the cable 1 of the present invention in the pulley 7.Under situation about being applied on the elevator, cable 1 is clamped in the pulley groove 8, and a motor (not shown) is used to rotating pulley 7, so that cable 1 is activated by the frictional force between cable 1 and the pulley groove 8.Pulley groove 8 is arranged in the liner 9, and liner 9 is installed in the pulley 7, and liner 9 is releasably attached on the pulley 7.Consider the frictional force of generation between liner 9 and cable coating 5 and possible wearing and tearing, liner 9 is formed from a resin, and is for example made by polyurethane, polyamide or polyethylene.Become flexible by using these resin materials can make with contacting of cable coating material, perhaps make elevator produce friction of viscoplasticity resin and enough frictional force, wherein cable coating material and above-mentioned resin material are similar.Can also substitute liner 9 by the application of resin material coating, so also can produce suitable frictional force and ABRASION RESISTANCE.
Fig. 4 is the cutaway view of second embodiment of the present invention's cable.The difference of this embodiment and first embodiment is: a fibre core 10 is installed on the center of cable 1.This fibre core 10 is by the such natural fabric of hemp or resemble polypropylene, polyester, polyamide, polyethylene, such synthetic fiber or the PBO of aromatic polyamide and make.When cable is subjected to tension force or is wound onto on the pulley and when crooked, this structure can reduce because the relative slip of steel strand wires 3 makes the wearing and tearing of steel wire 2 or wire coating 4 generations.In addition, the fibre core made from the high synthetic fiber of intensity 10 has improved the breaking strength of cable 1.In this case, set the twisting method of fibre core by following mode: the percentage elongation of the steel strand wires of being made by steel wire 2 and the percentage elongation of fibre core are complementary, so that load correctly is assigned on steel strand wires 3 and the fibre core.The cable core material of cable can be polyurethane, polyamide or polyethylene.
Fig. 5 is the cutaway view of the 3rd embodiment of the present invention's cable.The difference part of this embodiment and first embodiment is: the steel strand wires 3 that are arranged on the cable center are coated with steel strand wires coating 11.This steel strand wires coating 11 is made by resin material, for example polyurethane, polyamide or polyethylene.So just can reduce the wearing and tearing that make steel wire 2 or wire coating 4 generations owing to the relative slip of steel strand wires 3.All steel strand wires 3 all can be coated with the steel strand wires coating.
Fig. 6 is the cutaway view of the 4th embodiment of the present invention's cable.The difference part of this embodiment and first embodiment is: all steel strand wires 3 all are coated with steel strand wires coating 11.Like this, compare with the above embodiments, present embodiment can more effectively reduce the wearing and tearing that make steel wire 2 or wire coating 4 generations owing to the relative slip of steel strand wires 3.
Fig. 7 is the cutaway view of the 5th embodiment of the present invention's cable.The difference part of this embodiment and the 6th embodiment is: do not have coating on the steel wire, but all be coated with steel strand wires coating 11 on each steel strand wires 3 and be full of lubricant 12.Lubricant 12 is a kollag, for example molybdenum sulfide or graphite or lubricating grease.Owing to have a this structure, even therefore cable 1 is bent, lubricant 12 still can be used for reducing the wearing and tearing that the relative slip owing to steel wire 2 produces.Just in this point, compare with the 6th embodiment, can be by making every steel wire 2 all be coated with coating and lubricant further being sealed to the service life that mode in the every steel strand wires further prolongs cable.In the above-described embodiment, can prolong the service life of cable by the filler identical of filling in every steel strand wires with above-mentioned coating material.
Fig. 8 is the perspective view of first embodiment of the elevator of the above-mentioned cable wire of employing.In addition, Fig. 9 is a top view, there is shown the hoist trunk when present embodiment when the top is watched.
The pulley bearing of elevator cage 51 by being installed in elevator railway carriage bottom is on cable 53.One end of cable 53 is fixed on the building at supporting-point 54.Its other end is fixed on the building at supporting-point 55 by pulley 52, pulley 56 and counterweight pulley 58 that is installed on the counterweight 57 that is installed in elevator railway carriage bottom.Drive unit 59 rotates pulley 56, with the frictional force drives cable 53 by producing between pulley 56 and the cable 53, thereby moves in the vertical direction elevator railway carriage 51 and counterweight 57.This drive unit 59 is provided with a brake 60.
In Fig. 8, drive unit 59 is expressed as a gearless type drive unit that comprises a motor, but it also can be a gear type drive unit that adopts reduction gearing.As shown in Figure 9, can control elevator railway carriage 51 by guiding parts 61 and elevator railway carriage track 62, so that it only moves in the vertical direction.Equally, although not shown in the drawings, but still can control counterweight 57 by guiding parts and a counterweight track 63, so that it only moves in the vertical direction.In addition, elevator railway carriage 51 is provided with door 72a and the 72b that is positioned at elevator railway carriage side, so that it is relative with the stop side door 73a and the 73b that are positioned at aisle one side.In Fig. 8 and 9, drive unit 59 is suspended in the top of elevator railway carriage 51, but it also can be installed in the space between elevator railway carriage 51 and the lifting channel wall 64 by a less motor or reduction gearing.
When cable 53 is manufactured into structure shown in the foregoing description, to compare with the elevator that adopts conventional cable, the pulley 52, pulley 56 and the counterweight pulley 58 that are positioned at elevator car case bottom in Fig. 8 have less diameter.
The hoist trunk of elevator is provided with a pit that is used as free space in its bottom.In the structure of the cable that adopts the present invention, pulley 52 its diameters of elevator railway carriage bottom are very little, so just reduced the size of the elevator railway carriage bottom pulley 52 of stretching out from the elevator railway carriage downwards, and the also comparable pit of the prior art of pit is more shallow, thereby helps reducing the required cost of build building.
In addition,, therefore can alleviate the gross weight of elevator railway carriage, to allow the elevator railway carriage being quickened and deceleration with small driving force because the size of the pulley 52 of elevator railway carriage bottom can reduce.Like this, just can reduce to constitute the size of the driver or the motor of drive unit, thereby reduce power to the power source of driver part transmitting power.In addition, although not shown in the drawings, elevator railway carriage 51 generally also is provided with brake hard parts, and when cable 53 fractures, these brake hard parts can be braked elevator railway carriage 51.Because the gross weight of elevator railway carriage 51 and elevator railway carriage bottom pulley 52 reduces, so the required brake force of brake hard parts also diminishes, thereby makes the brake hard parts be lighter than traditional parts.
In addition, because the diameter of pulley 56 diminishes, therefore the rotating speed of the required pulley 56 of moving elevator railway carriage 51 increases at a predetermined velocity, and the moment of torsion that drive unit 59 is produced diminishes.In other words, drive unit 59 passes through less moment of torsion with bigger speed operation.Like this, if drive unit 59 is a kind of gearless type drive units, the diameter of motor is reduced.In addition, if adopt a gear type drive unit, so just can reduce the speed reducing ratio of reduction gearing or save reduction gearing.So just can reduce the installing space of the drive unit 59 at the top that is arranged at hoist trunk, thereby, under the very low situation of the building ceiling of attic, can reduce the overhang of hoist trunk.
As shown in Figure 9, in order to save the installing space of drive unit 59, pulley 56, counterweight pulley 58 and counterweight 58, preferably with in pulley 56 and the linear space that is installed between elevator railway carriage 51 and the lifting channel wall 64 of counterweight pulley 58 cardinal principles.Like this, when the diameter of pulley 56 and counterweight pulley 58 reduced, just moved along the direction of arrow A in the accompanying drawing installation site of counterweight pulley 58.So just enlarge the gap between the lifting channel wall 64 and counterweight 57 in the above-mentioned accompanying drawing, thereby can increase the width dimensions (the size B in the accompanying drawing) of counterweight 57.Like this, constructing identical required counterweight 57 thickness (the size C in the accompanying drawing) of counterweight of weight will diminish, thus can elevator railway carriage 51 and lifting channel wall 64 between space (dimension D in the accompanying drawing).Therefore, the shared space of hoist trunk is reduced.
In addition, adopt the cable 53 of the present invention shown in Fig. 8 and 9 to have following advantage.
At first, prolong the service life of cable 53, thereby prolonged the replacement cycle of cable.In other words, compare with the elevator that adopts conventional cable, the coefficient of friction between cable 53 and the pulley 56 is bigger, thereby can reduce the pressure of 53 pairs of pulleys 56 of cable.This pressure is that the tension force by cable produces, and the tension force of cable to be gross weight by elevator railway carriage 51 and counterweight 57 produce.Therefore,, can not produce slip between cable 53 and the pulley 56 yet, in other words, alleviate the gross weight of elevator railway carriage 51 and counterweight 57 even pressure diminishes.Therefore, just can reduce the manufacturing cost of elevator railway carriage 51 and counterweight 57, but also can reduce the power of drive unit 59 and power source.
In the embodiment shown in fig. 9, the pulley 52 of elevator railway carriage bottom and the longitudinal axis of pulley 56 are vertical mutually substantially, rather than extend along same direction.If the elevator that traditional flat belt is used for having this structure, belt will reverse between the pulley 52 of elevator railway carriage bottom and pulley 56 so.The flat belt that is twisted along inclined direction enters in the pulley 52 and pulley 56 of elevator railway carriage bottom, will produce concentrated wear like this or make the frictional behavior instability.Otherwise, because the cross section of cable 53 of the present invention be circular substantially, therefore and adopt the structure that may make the cable distortion even, the situation that concentrated wear also can not occur with make the unsettled situation of frictional behavior.
In addition, the resin fibre cable is subjected to that when irradiation ultraviolet ray may change or aging when it, therefore may directly or indirectly be radiated under the condition in the hoist trunk and be arranged in the outdoor sightseeing elevator at sunlight and can not use the resin fibre cable.On the contrary, cable of the present invention can adopt steel wire to make strengthening part, to be used for carrying.Therefore, even be exposed to ultraviolet ray down, cable also can not wear out, and can be applied under the above-mentioned condition.
In addition, under about 200-700 ℃ temperature, the resin fibre cable may sex change, thereby its intensity is sharply descended.Therefore, when being applied to the resin fibre cable on the elevator, according to the difference of its material and may since the fire in the building rupture.In addition, because the fire in the building and during heating, the sheathing resin material that is used to tie up stranded steel wire will melt, thereby makes the mutual tied up in knots of twisted wire, and elevator is broken down when the flat belt that is provided with stranded steel wire.On the contrary, cable of the present invention adopts steel wire as the strengthening part that is used to carry.Therefore, though hoist trunk because fire and heating also has only the resinous coat material just may melt, and the high strength of its intensity when still in the time of about 1000 ℃, keeping adopting traditional cable wire.Because when not using elevator during breaking out of fire in the building, therefore can be not directly the security of elevator not be impacted owing to occurring problem that fire reduces the durability of cable in the building, but when the building accident catch fire and elevator just in use, above-mentioned feature provides effective measures.
In addition, in the elevator that adopts traditional cable wire, adjustable height is big more, and the length of cable wire is also just long more.In this case, because cable must support the weight of himself, therefore must further improve the intensity of cable.In contrast, the traditional cable wire that equates with intensity is compared, and the weight of cable 53 its unit lengths of the present invention is less.Therefore, even when being used for cable of the present invention on the very big elevator of hoisting depth, this cable also can suppress the increase of the suspension load that causes owing to himself weight.
Cable of the present invention has lightweight advantage, when therefore changing old cable at the installation elevator or with new cable, will be easy to transportation, the installation and removal operation of cable.
In addition, in the combining structure of the cable wire of prior art and steel pulley,, cable wire and pulley produced noise owing to being in contact with one another.In the express elevator of pulley with rotation at a high speed, this situation is particularly evident.In contrast, when adopting cable of the present invention, because its surface applied has resin, and resin no matter therefore whether pulley is made by steel or resin, can both prevent the generation of contact noise than steel softness.
In addition, for preventing the wearing and tearing between the steel wire or between the steel strand wires, be full of lubricant in traditional cable wire.Therefore, just occur the possibility of greasy dirt, for example lubricant splashes and adheres on the clothes.In contrast, cable of the present invention does not make with lubricator, therefore greasy dirt will not occur.In a word, the cable wire of elevator can not be exposed in elevator railway carriage or the passenger part, and above-mentioned advantage can prevent effectively that lifting channel wall is contaminated, perhaps effective operating environment of improving maintenance and checking the workman.
In addition, the resin fibre cable has very big percentage elongation when bringing into use, and therefore, after a period of time after the installation, must adjust its length.This is because resin fibre than steel wire softness, therefore makes coadaptation of fiber phase and tight mutually contact just need the cost long time.In contrast, there is the structure of steel wire at cable of the present invention center, therefore compares with the situation of using traditional cable wire, and its initial percentage elongation will earlier settle out, thereby needn't adjust the length of cable once more.
Cable of the present invention is coated with resin on the surface, type that therefore can be by correct selection resin or pigment is mixed into makes it can be painted arbitrarily in the resin.Like this, for sightseeing elevator or outdoor elevator, color that can be by making cable is identical with the color of building or hoist trunk and do not make the existence that it should be noted that cable, the mode of the color that perhaps in contrast, can be by making cable and the TOTAL DIFFERENT COLOR of building or hoist trunk is given prominence to the operation of elevator.Perhaps, make the different piece of cable have different colors respectively, thereby, see different color combination according to the difference of the upright position of elevator railway carriage 51.In this case, need prevent that resin bed is separated from each other at the intersection of color.Therefore, pigment need not be pre-mixed in the resin, can pass through pigment and mixed with resin, meanwhile the resin continuously coating is also passed through to change pigment to be mixed to the excircle of cable main body, can be that resin bed is painted just, but also can guarantee that resin bed is a continuous layer with different colors.As mentioned above, can be by to the cable 53 painted design effects that improve.
Figure 10 is the top view of second embodiment of the elevator of employing the present invention's cable.Its difference part of present embodiment and embodiment shown in Figure 9 mainly is: counterweight 57 is installed on the different position.In other words, counterweight 57 is installed between the side and lifting channel wall 64 of elevator railway carriage 51, and wherein this side of elevator railway carriage 51 is positioned on the position relative with elevator side door 72a, 72b.Therefore, pulley 52, pulley 56 and the drive unit 59 of elevator railway carriage bottom just are installed on the different positions.These structural difference are that the restriction by the building general layout causes.As shown in figure 10, in this embodiment, the pulley 52 of elevator railway carriage bottom and the longitudinal axis of pulley 56 extend along different directions, and the longitudinal axis of pulley 56 and counterweight pulley 58 also extends along different directions.That is, cable is being twisted between pulley 52 and the pulley 56 and is further being twisted between pulley 56 and counterweight 58.Therefore,, compare with the structure shown in 9 with Fig. 8 so, just may produce concentrated wear, or make the frictional behavior instability if in having the elevator of this structure, adopt traditional flat belt.But if cable of the present invention is applied in the structure shown in Figure 10, the unsettled phenomenon of concentrated wear and frictional behavior will not take place so, because the cross section of cable is roughly circle, this is a feature of the present invention.In other words, present embodiment is a kind of structure that can make full use of the advantage of cable of the present invention more.
Figure 11 is the perspective view of the 3rd embodiment of the elevator of employing the present invention's cable.In this embodiment, top pulleys 65 and 66 is used in the bottom of hoist trunk pulley 56, drive unit 59 and brake 60 being installed.The major advantage of this structure is: the drive unit 59 that may produce noise can be installed in the bottom of hoist trunk, rather than be installed in the top of hoist trunk, because in the bottom of hoist trunk, noise is difficult to become problem, but at the top of hoist trunk, the easiest propagation of noise.In addition, compare with the embodiment shown in 9 with Fig. 8, the whole length of cable 53 and weight will be distinguished elongated and become heavy, therefore need plenty of time and energy to finish the problem of fitting operation with regard to existence.But, when in this structure, using cable of the present invention, just can make the weight saving of whole cable and fitting operation become easy.In other words, this embodiment is a kind of structure that makes full use of the present invention's the lightweight advantage of cable more.
Figure 12 is the perspective view of the 4th embodiment of the elevator of employing the present invention's cable.In this embodiment, the position of counterweight 57 shown in Figure 11 is arranged on elevator railway carriage back shown in Figure 10.Certainly, the problem that exists Figure 10 and 11 illustrated embodiments to relate among this embodiment, that is, in Figure 10, cable 53 is twisted two positions, in Figure 11, because the length of cable is very long, has therefore just increased the weight of whole cable.But the cable of the application of the invention just can prevent concentrated wear and frictional behavior problem of unstable, but also can alleviate the weight of whole cable, even requiring cable to produce in the structure of distortion.
Figure 13 is the perspective view of the 5th embodiment of the elevator of employing the present invention's cable.In this embodiment, pulley 56, drive unit 59 and brake 60 are installed in the top of hoist trunk or one and are arranged in the machine room of hoist trunk top.The elevator railway carriage is supported and is suspended on the cable 53 by a vertical frame 69 and a crosshead 70 by an elevator car tank tower 68.One end of cable 53 is connected on the crosshead 70, and the other end then is connected on the counterweight 57 by pulley 56 and deflecting wheel 67.Pulley 56 is rotated, with by the frictional force drives cable 53 between pulley 56 and the cable 53, thus moving elevator railway carriage 51 and counterweight 57.Supporting elevator railway carriage 51 and adopt deflecting wheel 67 by elevator car tank tower 68 is not the requisite requirement of the present invention.
This embodiment can be widely applied in the structure of elevator, but this structure also can adopt cable of the present invention.Therefore particularly, in the structure of present embodiment, deflecting wheel 67 often is used, and compares with the structure that does not adopt deflecting wheel, and winding angle is that the angular range that is wound on the pulley 56 of cable 53 is less probably.Frictional force between pulley 56 and the cable 53 has the characteristic that reduces continuously with winding angle.Therefore, the frictional force deficiency is so that cable 53 produces the tendency of sliding on pulley 56.On the contrary, compare, when adopting cable 53 of the present invention, can obtain higher friction power, thereby a kind of reliable elevator that can prevent that cable 53 from skidding is provided with traditional cable wire.
Figure 14 is the perspective view of the 6th embodiment of the elevator of employing the present invention's cable.This embodiment has adopted relative its diameter to have slim cylindrical drive device 59, brake 60 and the pulley 56 of less thickness.Therefore, by drive unit 59 being arranged in the space between hoist trunk and the elevator railway carriage 51, just can reduce the headroom of hoist trunk, in other structure, drive unit is installed in the headroom of hoist trunk.Drive unit 59 in the present embodiment preferably is made of a kind of permanent-magnet type gearless synchronous motor.In this case, if the diameter of pulley 56 is very big, the rotating speed with the pulley 56 of identical speed moving elevator railway carriage 51 is just very little so, and the moment of torsion that is produced by drive unit 59 will increase.Therefore, the diameter of the motor of formation drive unit 59 must be very big.In contrast, when adopting cable of the present invention, the diameter of pulley 56 can reduce, thereby the diameter of drive unit 59 is suitably reduced, to reduce the size of hoist trunk.
Figure 15 is the perspective view of the 7th embodiment of the elevator of employing the present invention's cable.In this embodiment, elevator railway carriage 51 is suspended on the hitch point 71 by cable 53.Cable 53 is connected with counterweight 57 by pulley 56.This structure hangs elevator railway carriage 51 without any need for vertical frame or crosshead, so it has the advantage of simplifying elevator railway carriage surrounding structure.In addition,, comprise that the whole height of elevator railway carriage and crosshead also reduces, therefore just a less exceptional space can be set at the top of hoist trunk owing to do not need crosshead.Like this, owing to drive unit 59 is installed in this additional space, so the height dimension of drive unit 59 is more little, and exceptional space is also just more little.Therefore, when adopting cable of the present invention, the diameter of pulley 56 can be very little, and the diameter of the motor of formation drive unit 59 also can be very little, thereby the height dimension of drive unit 59 is reduced.Like this, just can make the exceptional space that is arranged on the hoist trunk top less.
Figure 16 is the perspective view of the 8th embodiment of the elevator of employing the present invention's cable.The structure of this embodiment is as follows: drive unit 59, brake 60 and pulley 56 are installed in the inside of counterweight 57, and cable 53 is driven by pulley 56, to move in the vertical direction elevator railway carriage 51 and counterweight 57.In the structure of this embodiment, will drive unit and like be installed in the side of building, therefore compared with prior art, can reduce the space of hoist trunk.But,, must reduce the size of these parts for drive unit 59, brake 60 and pulley 56 are installed in the counterweight 57.Otherwise, if adopt cable of the present invention, so just can reduce the diameter of pulley 56, thereby drive unit 59 and brake 60 are diminished, so just these parts can be installed in the counterweight 57.
In Figure 16, drive unit 59, brake 60 and pulley 56 are installed in the counterweight 57, but under situation about these parts being installed on the elevator railway carriage 51, cable that can the application of the invention and obtain same effect.
Figure 17 is the perspective view of the 9th embodiment of the elevator of employing the present invention's cable.This embodiment is a kind of structure with following characteristics: elevator railway carriage 51 and counterweight 57 interconnect by top pulleys 65 and cable 53, guide rail 76 is installed between driving rolls 74 and the pressure roller 75, drive unit 59 is used to rotate driving rolls 74, to move in the vertical direction elevator railway carriage 51 and counterweight 57.Similar to embodiment shown in Figure 16, this embodiment does not need drive unit and other parts are installed on the side of building, so it has the effect that reduces the hoist trunk space.Here, in order to bear suspension load in the side that does not make building, this structure preferably makes top pulleys 65 be bearing on the guide rail 76.But, in order not increase hoist trunk, top pulleys 65 need be installed in the following manner: make it move its center from guide rail 76 along continuous straight runs.In this case, the moment of flexure that is produced by suspension load acts on the guide rail 76, so just makes the guide rail bending easily.In contrast, if adopt cable of the present invention, the size of top pulleys 65 just can reduce so, thereby reduces horizontal displacement and moment of flexure between top pulleys 65 and the guide rail 76.Therefore, can reduce the weight of guide rail 76.
Except that above-mentioned elevator, cable of the present invention also may be used in other field.A kind of application as wherein is illustrated the situation that the present invention is applied on the crane below.Generally speaking, crane is generally used for outdoor or is used in the bigger interior space, and the cable that constitutes crane is exposed in wind and rain and the dust.Therefore, by corrosion or dust and the wearing and tearing that produce will be shortened the service life of cable.In contrast, because cable surface applied of the present invention has resin bed, directly be not exposed in wind and rain or the dust as the stranded steel wire of reinforcing section.Therefore, compare with traditional cable wire, the present invention can prolong the life-span of cable.
In addition, in cable of the present invention, can carry out painted to the surface of resin bed at an easy rate.Therefore, by the resin bed on surface being coated multiple different color, make the operating personnel of crane or carry out steel wire around the crane and handle the workman of operation and find these cables easily.Therefore, can make crane with good safety and operability.In this case, the color of the surface resin layer of cable is preferably yellow, orange with different iridescent.But if the color of surrounding environment and above-mentioned color are similar, so this color relation can not improve visibility, should adopt other color certainly.
As an example in other Application Areas that applies the present invention to except that elevator, will be applied to hanging basket in the skifield or the situation on the lift below to the present invention's cable and be illustrated.Hanging basket or lift usually in the mode that is similar to crane in outdoor application, as mentioned above.Cable of the present invention is coated with resin, so it has the life-span of good weather fastness and overlength.
In addition, the traditional cable wire outward appearance and the scenery of skifield are not complementary, because steel wire is under the state of exposing.And that cable of the present invention can easily carry out surface resin layer is painted, therefore can produce in appearance the lift that can match with scenery.For example, make lift not noticeable if desired, cable preferably is coated with white or the light colour approximate with white so.Otherwise if desired that lift is noticeable on its bearing of trend, resembling redness, blueness or green such visible color so is suitable color.Particularly, can pass through the different color of coating on the cable of contiguous lift, and make the passenger easily identify optional moving direction.
In addition, for the chair type lift, the passenger be sitting in just cable wire below.Like this, a problem will occur: according to the difference of the mode of lubricant applications to the cable wire, the lubricant droplet that passenger's clothes may be fallen is made dirty.But cable of the present invention does not need to make with lubricator, therefore needn't worry passenger's the clothes of making dirty.
By the way, the cable that is used on the lift of skifield must be annular, that is, the opposite end of cable must link together.For traditional cable wire, be to take apart by the steel strand wires that will constitute cable, the mode that will be woven together from the steel strand wires that opposite end stretches out by joint technology manufactures annular with cable then.In contrast, cable of the present invention can be manufactured into annular by following operation:
Remove a standing part of the face coat resin that is positioned at the cable two ends.Then, the steel strand wires that constitute cable wire are untied, and the steel strand wires that will stretch out from two ends by joint technology are woven together.Next, to the part handled application of resin material once more.
In this case, if rainwater or the analog part by coating again is penetrated in the cable, cable just may corrosion so, and also variation of its intensity.Therefore, must on this part, be coated with application layer in weather-proof mode at least.As a preferred example, can perhaps one resin strip be wound on the cable by heating pipe of making by heat-shrinkable resin of suit on cable with pressure adhesive.Perhaps, can use the interface between the resin of original surface resin layer of encapsulant sealing and coating again and make cable have more weather proof.
The present invention who makes in the above described manner can prevent the cable lost of life that reduces to cause owing to the elevator pulley diameter, perhaps prolongs the life-span of cable.Therefore, the present invention can reduce to include the size and the weight of the equipment of a motor and an elevator, and save the required space of elevator is installed, but also can be by prolonging the security that improves whole device service life and the reliability of cable.
