The specific embodiment
Followingly one embodiment of the invention are described with reference to accompanying drawing.
Fig. 1 is the whole pie graph of one embodiment of the invention.
In Fig. 1, the axle 16 of local derviation pulley 11 and rope sheave 10 being arranged to local derviation pulley 11 and rope sheave 10 spools 15 substantially parallel.In addition, it is substantially parallel with elevator car upper deflection sheave axle 18 counterbalanced weight deflection sheave 5 and elevator car upper deflection sheave to be arranged to the deflection sheave axle 17 on counterbalanced weight top.And hoist cable is wrapped on each pulley.In Fig. 1, the elevator user takes advantage of into elevator (counterbalanced weight is positioned at the rear side of lift car) from the right left of accompanying drawing.
In Fig. 1, on the beam in being arranged at Machine Room floor face 1 (not shown) etc. single pole 2 is installed, on single pole 2, connecting the two ends of resin-coating hoist cable 3.Sagging to the bottom hoist cable along hoist trunk from an end of this hoist cable, the one end is wrapped on the deflection sheave 5 that is positioned at counterbalanced weight 4 tops and extends upward.This deflection sheave 5 is arranged on the parallel direction of the length direction that makes counterbalanced weight 4 and deflection sheave axle 17.This is owing to wearing and tearing in resin-coating hoist cable 3 the special surface abrasions of abstaining from, that produce in the side of pulley groove can be reduced to minimum cause.That is to say, for fear of reversing of 90 ° of appearance between axle 16 that is installed in the local derviation pulley 11 on the platform 26 and the hoist cable, so that the axle 17 of deflection sheave 5 mode parallel with spools 16 of local derviation pulley 11 is arranged to make deflection sheave axle 17 parallel with the length direction of counterbalanced weight 4 deflection sheave 5.
When using traditional steel hoist cable, because the bending spring of steel hoist cable is big, so, deflection sheave 5 can only be arranged to itself and the length direction quadrature of counterbalanced weight.Promptly, if it is parallel with the length direction of counterbalanced weight deflection sheave 5 to be arranged to its direction, then because the bending spring of steel hoist cable is big, so thickness (left and right directions of accompanying drawing) with respect to counterbalanced weight 4, it is big that the diameter of deflection sheave 5 becomes, and, increase this problem so the sectional area of hoist trunk can occur because the diameter of this pulley determines spacial size.For this reason, do not adopt the direction method to set up parallel of deflection sheave 5 being arranged to it with the length direction of counterbalanced weight.
In the present embodiment, adopted the less minor diameter resin-coating hoist cable of restriction of bending spring aspect, the diameter of deflection sheave can be provided with littler than the thickness of counterbalanced weight, owing to will pulley be arranged to the length direction quadrature with counterbalanced weight, so suppressed the increase of counterbalanced weight thickness on the whole.But,,, need improve intensity by increasing radical, thereby cause the thickness of pulley to increase in order to support the weight of lift car and counterbalanced weight if use the hoist cable of minor diameter.At this moment, in the machine of present embodiment is arranged, since sheave shaft to thickness increase the form that increases with the length of pulley on the counterbalanced weight length direction and occur, and the increase of end wise is almost without any restriction, so the increase of hoist cable radical can not cause new problem, owing to avoiding reversing fully, prolong the hoist cable effect in service life so have along with the hoist cable that flank wear produces.
The other end of hoist cable 3 is sagging towards the below along hoist trunk from single pole 2, is wrapped in elevator car upper deflection sheave 9 back change of directions and extension up.Deflection sheave 9 is installed on the not shown angle steel, and its axle 18 stretches out from crosshead 8.Crosshead 8 is at the top with the mode of level and the framework 7 of taking advantage of two settings about Inbound at lift car and links.Elevator car frame 7 links in bottom and platform 6, and elevator cages 13 is installed on the platform 6 across vibration-proof rubber spare 12.In addition, the elevator lobby flooring 14 of each floor is positioned at the position relative with elevator cages 13, and user 19 is by the elevator door 27 that is positioned at the accompanying drawing left and right directions elevators of coming in and going out.In the machine arrangement that present embodiment proposes, the axle 18 of elevator car upper deflection sheave 9 be arranged on be installed in platform 25 on the axle 15 parallel directions of rope sheave 10 of electrical motor 20 on, owing to torsion phenomenon can not occur, so, even in the chute side of elevator car upper deflection sheave 9, the side of resin-coating hoist cable can not be worn yet.That is, because all 4 S. A.s all be arranged in parallel, so reversing can not appear in resin-coating hoist cable fully, like this, the resin hoist cable cannot cause the life-span to be reduced fully because of this factor of flank wear.And, aspect the deflection sheave 9 of lift car side, because lift car originally just has enough depth, thus can be as counterbalanced weight 4, because of the thickness (depth) of lift car and the relation between the diameter of pulley size go wrong.And, because axle 18 be arranged in parallel with crosshead 8, so be installed in the angle steel at a two ends can be directly and crosshead link, so also produced another effect, promptly, compare with the vertically disposed traditional arrangement method of axle and crosshead, become more convenient (specifically being arranged among Fig. 2 of machine describes in detail) is set.In addition, if, then can pulley be divided into several, and a plurality of middle angle steel, the joining line of going forward side by side are set suitably between the partition type pulley at direction of principal axis because of the length increase of axle causes deflection of shaft significantly to aggravate.And, owing to adopted the bottom that elevator car upper deflection sheave 9 is arranged on crosshead 8, the structure that hoist cable is passed from the below of crosshead, so, gap size between decision hoist trunk top and elevator car roof, that is, built on stilts apart from the time, deflection sheave no longer is an a crucial factor, so also have the effect that can shorten built on stilts size.
From the upwardly extending hoist cable of the counterbalanced weight side of hoist trunk bottom twine be linked in vertical plane with the overlapping local derviation pulley 11 of counterbalanced weight top deflection sheave 5 on, from the upwardly extending hoist cable of the lift car side of hoist trunk bottom twine be linked in vertical plane with the overlapping rope sheave 10 of elevator car upper deflection sheave 9 on.And elevator drive is connected with rope sheave 10 with coaxial manner with electrical motor 20.Because the hoist cable relation of twining, single pole 2 is arranged on than in the residual spaces more in the inner part such as local derviation pulley 11 and rope sheave 10, like this, though carry out hoist cable cut short operation the time some inconvenience, help effective utilization to the Machine Room flooring.In traditional elevator device, owing to can't guarantee big binding force between steel hoist cable and the steel pulley, so taked hoist cable on rope sheave, to twine two circle canoes of two circles, and in the present embodiment, since adopted surface material than the more soft resin-coating hoist cable of the surface material of other pulleys as main hoist cable, so, consider to prolong this point in service life of resin-coating hoist cable from override, for the length of contact with rope sheave and hoist cable is controlled in the minimum zone to reduce the surface abrasion of hoist cable, and in order to reduce to playing material hoist cable number of bends the service life of heart yearn, make the number of bends of the hoist cable in rope sheave and the local derviation pulley reduce to original 1/3rd, and, in order to prolong the service life of resin-coating hoist cable from surface and inner this two sides, adopted hoist cable on rope sheave and local derviation pulley, only to twine the individual pen canoe of a circle.And, in two circle canoes, the center of hoist cable only is offset the distance that a hoist cable adds the upper hopper chute width, so, strictly speaking, hoist cable rubs mutually with the side of chute, even avoid this point, the individual pen winding method of the resin-coating hoist cable that is proposed concerning the wear-out life that prolongs the surface, especially prolong the wear-out life of side very effective.
In addition, in high speed with above in the elevator of high-speed operation, because the volume of electrical motor 20 is big, so the accurate elevator of image scale is such, the vertical direction that electrical motor is arranged on counterbalanced weight 4 is not a good method, in this programme, adopt and used the standard lift diverse ways of resin-coating hoist cable, by electrical motor being arranged on the vertical direction of elevator car upper deflection sheave 9, thereby the machine in the Machine Room has been occupied spatial control in the limit of minimum.And, in this arrangement, because counterbalanced weight is arranged on the rear side of lift car, so also have following effect, that is, and when a plurality of elevators laterally form a line and form an eleva-tor bank, also can form a group elevator system, in this group elevator system, the wearing and tearing and the bending of resin-coating hoist cable can appear hardly, so can prolong the service life of hoist cable.Furthermore, the machine arrangement of present embodiment also has following effect, promptly, even taking advantage of the offset load that has occurred lift car on the Inbound, because its moment of rotation is consistent with the hand of rotation of deflection sheave, so can not produce the unfavorable condition that the resin-coating hoist cable is worn in the side of deflection sheave 9 because of offset load takes place.
Engine arrangement when Fig. 2 represents in one embodiment of the invention to overlook Machine Room and hoist trunk from the top.Figure (a) is the figure when the Machine Room ceiling is overlooked the Machine Room flooring, and figure (b) is the figure when hoist trunk is looked up in floor below in Machine Room.The dotted line of connection diagram (a) and figure (b) is represented the annexation of a hoist cable in the many hoist cables.Can know that from figure (a) hoist cable extends along hoist trunk from single pole 2 downwards, deflection sheave 5,9 upwardly extending hoist cables by counterbalanced weight and lift car respectively, the top by local derviation pulley 11 and rope sheave 9 is provided with, and does not wherein occur reversing.From figure (b) as can be seen, for hoist cable being directed to top and not contacting with crosshead 8, the diameter of deflection sheave 9 is set to bigger than the width of crosshead, the deflection sheave 9 that is divided into a plurality of (being two herein) at direction of principal axis, fix in the place of necessity by three angle steel 21, it is installed in the bottom of crosshead 8, promptly near on the position of lift car side.This be because, in order to strengthen main hoist cable single-piece suspention intensity, be used to realize that with many minor diameter resin-coating hoist cable of pulley minor diameterization is wrapped in pulley.Angle steel is directly installed on the crosshead in many places, and axle 18 is parallel with the direction of crosshead 8, and this method for arranging reduces the effect that constitutes amount of parts except having, and also has the effect that prevents bending shaft.And, the structure that employing will these a plurality of partition type pulley combinations be got up, in the time need changing the intensity of hoist cable because of varying in weight of lift car, can be by increasing or reduce the radical of hoist cable, the number that promptly increases or reduce pulley is adjusted, so have following effect, promptly do not need to prepare the pulley of plurality of specifications, also can realize normalisation.In addition, the relation between the life-span of the minor diameter hoist cable of many windings and the lower limit of diameter of pulley also is applicable to the occasion of rope sheave, so rope sheave also can adopt the pulley of minor diameter.When using the rope sheave of minor diameter, if wish to obtain the elevator car speed of regulation, electrical motor has high rotating speed and a little torque characteristics with employing electrical motor is for well, and this means under the capacitance unmodified situation of drive motor, the volume of electrical motor can be dwindled by equivalence deceleration effect, the effect that the Machine Room is provided with can be more easily electrical motor moved into thereby have.And, though the minor diameter resin-coating hoist cable of many windings has cumbersome this disadvantage of adjusting at aspects such as Tension Control, also have following effect, promptly, when a hoist cable damaged, its degree to the adverse effect that total system caused had obtained reduction.And, lift car at various weight, can regulate the comprehensive strength of main hoist cable part by the radical of adjusting hoist cable,, therefore have the development cost that can reduce the resin hoist cable and the effect of development time so there is no need to prepare the different resin-coating hoist cable of multiple hoist cable diameter.Again, owing to can control the character of surface of resin-coating hoist cable to a certain extent, so can improve the binding force of resin-coating hoist cable, therefore, needn't between steel pulley and steel hoist cable, cooperate, special cutting type chute shape must be adopted in order to ensure binding force, and the pulley groove in the simple rounded cross section of processing can be used.
Fig. 3 represents an alternative embodiment of the invention.Be with the difference of Fig. 1, in the machine arrangement that Fig. 3 proposes, be installed in the space of stipulating in the building in order to lack the platform elevator even occur, and with the installation site of counterbalanced weight when rear side makes the situation of side into, also the flank wear of hoist cable and bending etc. can be controlled in the minimum scope, thus the life-span that can guarantee long hoist cable.So-called " counterbalanced weight is installed in side " refers to counterbalanced weight is arranged in lifting on the position of taking advantage of the Inbound quadrature with lift car.At this, elevator user 19 with the perpendicular direction of accompanying drawing on the lift car of coming in and going out.Compare with the method to set up of Fig. 1, its difference is, the axle 18 and the crosshead 8 of the deflection sheave 9 of elevator car upper is in the position relation of having rotated 90 °, rope sheave 15 is not overlapping in vertical direction with elevator car upper pulley 9, move towards a lateral deviation opposite with lift car side single pole 2, and the deflection sheave 9 of elevator car upper than crosshead 8 by the top.After axle and crosshead half-twist were provided with, even be arranged in the elevator device of side at counterbalanced weight, the situation that hoist cable also can not occur reversing was so have the effect that prevents flank wear.Single pole 2 is arranged on the outside, make rope sheave and the approaching effect of local derviation pulley, it is the winding angle to strengthen hoist cable and be wrapped on the rope sheave time, like this, then can adopt resin-coating hoist cable, and electrical motor can be arranged on the position that is positioned at the center on the vertical projection of counterbalanced weight and lift car with a little bit poorer a little character of surface of binding force.In addition, the deflection sheave of elevator car upper being arranged on locational effect than cross head height, is can reduce noise and Applicable scope can be expanded on the hyper-velocity elevator.That is, though this method to set up is not very favourable on built on stilts size, in fireballing elevator, built on stilts size is original just very big, so this point can not become big problem.On the other hand, the noise that contacts between pulley and the hoist cable and form can strengthen along with the rising of speed, but as long as sound pollution source and elevator cages are kept apart, then can reduce the harmful effect of noise, so this method to set up for example is very suitable for the pulley circular velocity more than or equal to the elevator device of 600m/min.
Fig. 4 is the engine arrangement of the elevator car upper among another embodiment of the present invention.This figure is the figure when elevator car upper is seen in the Machine Room.Among the figure, the axle 18 of the deflection sheave 9 of elevator car upper is arranged on the position with crosshead 8 quadratures, and two deflection sheavies 9 are that the center is arranged on the left and right sides evenly with the crosshead, in central authorities angle steel 21 are set, and are installed in the top of crosshead 8.In central portion angle steel installation shaft 18, angle steel is simple structure, can obtain the effect of cost-cutting.If the quantity of elevator car upper pulley 9 as shown is even number, then can be arranged in the structure that distributes about middle body, if odd number, then frame is on many crossheads 8, or angle steel is made into " order " font, and with in the pulley embedded space, like this, just sound pollution source and lift car can be spaced apart.
Fig. 5 represents another embodiment of the present invention.Be that with the difference that is provided with of Fig. 1 single pole 2 is separately positioned on the outside of hoist cable.Its result, local derviation pulley 11 is not overlapping with counterbalanced weight top 5 in vertical plane, and rope sheave 10 is not overlapping with elevator car upper pulley 9 in vertical plane.Its effect is to make local derviation pulley and rope sheave further approaching, so the winding angle in the time of can making the resin-coating hoist cable be wrapped on the rope sheave is bigger, though adhesiveness is not very good, but owing to can adopt resin-coating hoist cable with excellent surface frictional behavior, and single pole partly is positioned at the outside of the hoist cable of downward extension, can carry out the effect that hoist cable is cut short operation easily so have.Certainly, prolonging aspect the basic effect in hoist cable life-span, such as there not being 90 ° to reverse so can not cause flank wear fully, so and since number of bends to reduce aspects such as the degree of injury that heart yearn is caused alleviates identical with the embodiment of Fig. 1.
Fig. 6 represents another embodiment of the present invention.Be that with the difference that is provided with of Fig. 5 therefore the elevator user has and can realize that small-sized counterbalanced weight is positioned at the effects such as elevator device of side going into the perpendicular direction of accompanying drawing is superior.And, can prevent that the resin hoist cable is worn, by reducing crooked number of times to prevent that heart yearn is caused damage, because of the raising of binding force can be used the resin hoist cable of surface material through strengthening, and the operation effect such as more convenient that becomes of cutting short of hoist cable does not reduce fully.
Fig. 7 represents another embodiment of the present invention.Be that with the difference that is provided with of Fig. 6 in the single pole 2, a single pole that is positioned at the balance heavy side is arranged on the outside of hoist cable, and the axle of counterbalanced weight top deflection sheave is arranged on the direction with the length direction quadrature of counterbalanced weight.Need near operation single pole when hoist cable is cut short, but in the ordinary course of things, owing to can cut off operation in a side, so, the single pole of lift car side is arranged in the residual space can't bring big overslaugh to operation, because an outside that is positioned at the hoist cable of downward extension in the single pole is so have the effect that the operation of making becomes more convenient.On the other hand, length direction with respect to counterbalanced weight has reversed 90 ° because axle is on the top of counterbalanced weight, so compare with the embodiment of Fig. 1 to Fig. 6, aspect flank wear, want a little bit poorer, but because axle and length direction quadrature, so have the effect that can increase the deflection sheave of balance heavy side diameter.In this method to set up, as the resin-coating hoist cable, if use character of surface through strengthening and having strengthened core line diameter to improve the major diameter resin-coating hoist cable of tensile strength in order to adapt to use in the high capacity elevator device, consider that from this point in service life that improves hoist cable the major diameter pulley must be arranged on the counterbalanced weight.In addition, present embodiment also has and can realize a kind of effect of using the elevator device of major diameter resin-coating hoist cable.
Figure when Fig. 8 is Machine Room from top birds-eye view 7 embodiment and hoist trunk.Its graphic technique is identical with Fig. 2, (a) expression Machine Room, and (b) expression hoist trunk, the dotted line that connects both is represented the method to set up of hoist cable.The flank wear of resin-coating hoist cable just just might take place in the part of local derviation pulley 11 and counterbalanced weight top deflection sheave 5.
Fig. 9 represents another embodiment of the present invention.Be with the difference that is provided with of Fig. 7, in the deflection sheave of lift car side, also occurred 90 ° and reversed.Identical with Fig. 7, the method to set up of present embodiment also is highly suitable for using the elevator device of major diameter resin-coating hoist cable.Because elevator car upper is different with the balance heavy side, has sufficient space aspect the major diameter deflection sheave being provided with, so, as long as when the decision counterbalanced weight breaks away the diameter of taking turns, satisfy the thickness of hoist cable heart yearn and the restriction condition relevant of bending spring with the hoist cable life-span, and the diameter value of lift car sideslip wheel and the diameter value of counterbalanced weight sideslip wheel are complementary, just can the same with the embodiment of Fig. 7 the resin-coating hoist cable be applicable to high-capacity elevator, thereby can obtain to reduce the effect of electrical motor volume.
Figure when Figure 10 represents Machine Room from top birds-eye view 9 embodiment respectively and hoist trunk.Owing to used large diameter resin-coating hoist cable, so can reduce the radical of hoist cable, can correspondingly shorten the axial length of deflection sheave, its result thus, can play and dwindle two places and reverse the caused angle of reversing, thereby the effect that reduces flank wear is arranged.
Figure 11 represents another embodiment of the present invention.In the present embodiment, be not use deflection sheave with the difference of the embodiment of Fig. 1 to Figure 10, the end of hoist cable links with balance heavy side connecting part 23 and lift car side connecting part 24 respectively.The characteristics of present embodiment are, the formed average column direction of many resin-coating hoist cables that is attached at balance heavy side connecting part 23 is parallel with the axle 16 of local derviation pulley 11, the formed average column direction of many resin-coating hoist cables that is attached at lift car side connecting part 24 is parallel with the axle 15 of rope sheave 10, and the axle 15 of rope sheave 10 is parallel with the axle 16 of local derviation pulley 11.Thus, the surface of resin-coating hoist cable becomes very little in the possibility that the chute side of rope sheave and local derviation pulley is worn, thereby has improved surperficial wear-out life.And hoist cable adopts a circle canoe to be wrapped on rope sheave and the local derviation pulley.Like this, when adopting two circle canoes, be wrapped in hoist cable on the pulley and move to when the adjacent chute the flank wear that moves along the side of chute and cause and compare, have the effect that reduces flank wear the resin-coating hoist cable.And, one circle winding method has the effect that reduces the winding number of times, can be reduced to 1/3rd of two traditional circle canoes with being played material number of bends the broken string life-span of heart yearn, so in the elevator device that adopts 1 pair 1 canoe, also can obtain the effect that prolongs the resin-coating hoist cable life-span from wearing and tearing and this two aspect that breaks.
Like this, according to present embodiment, in the elevator device that uses the resin-coating hoist cable, can pass through setting and the arrangement of hoist cable end and the winding method of hoist cable etc. of the various pulleys such as deflection sheave of improvement rope sheave, local derviation pulley, moving body, getting rid of life-span to hoist cable has material surface abrasion, heart yearn broken string and clad and senile cause such as peels off, and can prolong the hoist cable effect in service life thereby have.
And, according to present embodiment, owing to improved the reliability of service of resin-coating hoist cable, so, therefore can in elevator, use the drive motor of high speed revolution and little torque, have and to make motor miniaturization, the elevator machine chamber can be set, can make the setting of the machine effects such as freedom that become more.
