Description
Technical field
The present invention relates to a kind of elevator device, especially relate to and a kind ofly connect lift car and counterbalanced weight by main hoist cable, the rope sheave through winch carries out elevator to this main hoist cable, the elevator device that relies on the friction between main hoist cable and the rope sheave that lift car is gone up and down.
Background technology
In general, elevator device (being designated hereinafter simply as " elevator ") adopts mode of traction to drive usually.In the elevator that adopts this mode of traction, utilize main hoist cable suspention lift car and counterbalanced weight, and main hoist cable is carried out elevator through winch, make lift car and counterbalanced weight in the opposite direction carry out oscilaltion thus.
In recent years, the elevator of machine House-less has become the main flow elevator gradually, and the principal feature of the elevator of machine House-less is that winch is arranged in the hoist trunk.The elevator of this kind machine House-less roughly can be divided into 2 kinds of structures, is about to that winch is arranged on the structure of lift car or counterbalanced weight top and winch is arranged on the structure in the space of lift car and hoist trunk between the walls.
The elevator of above-mentioned machine House-less adopts so-called 2: 1 hoist cable winding method mostly, that is to say, utilizes the principle of movable pulley, on lift car and counterbalanced weight, pulley is set, and makes winch equal 2 times of amount of movement of lift car to the coiling amount of main hoist cable.Adopt 2: 1 hoist cable winding method, required power in the time of can reducing winch and reel.
According to said structure, with winch the coiling amount of main hoist cable and identical 1: 1 the hoist cable winding method of amount of movement of lift car are compared, can reduce the required torque of reeling, so can make the winch that constitutes by electrical motor etc. realize miniaturization.
On the other hand, concerning the hoist trunk of the terraced car move inside of supplying power, the requirement in channel cross-sectional area and the gap between elevator car roof and the hoist trunk top of horizontal surface of dwindling hoist trunk is very urgent.
For this reason, technological as formerly, a kind of scheme has been proposed; It is in 2: 1 hoist cable winding method of employing; Many winchs (comprising electrical motor) are set, and use the little miniature electric motor of torque rating, dwindle the gap between elevator car roof and the hoist trunk top thus.
As machine room-less elevator that has dwindled gap between elevator car roof and the hoist trunk top and the elevator that used multiple motors, for example proposed by patent documentation 1 disclosed elevator.
In patent documentation 1 disclosed elevator; Illustrated in figures 1 and 2 like patent documentation 1; Adopt 1: 1 hoist cable winding method, connect the lower end and the counterbalanced weight of lift car, and the winch that has adopted external-rotor motor is set at the hoist trunk top with main hoist cable.Thus, can realize a kind ofly the Machine Room need not being set, and can dwindle the structure in gap between elevator car roof and the hoist trunk top as far as possible.
In addition; In patent documentation 1 disclosed elevator; Like Fig. 4 of patent documentation 1 and shown in Figure 5; Also proposed to connect the top and the counterbalanced weight of lift car with main hoist cable, the structure that two electrical motors are set above the counterbalanced weight and lift car and counterbalanced weight separately above the structure of electrical motor is set.
According to said structure, through winch being divided into two winchs, compare with the occasion that adopts a winch to drive, can be at half by the torque drop that the electrical motor of each winch is required, its result can make winch realize miniaturization.

Patent documentation
In patent documentation 1 disclosed elevator structure; Be arranged on the structure in the gap of lift car and hoist trunk between the walls for the structure that realizes that Machine Room this purpose is not set, adopted winch is set and with winch above lift car or counterbalanced weight.
In the winch of patent documentation 1, adopted leptosomatic external-rotor motor., under the occasion of using wire sling, when being wound on main hoist cable on the rope sheave, can receive the restriction of the rate of curving aspect of wire sling.If limpingly main hoist cable is wound on the little rope sheave of the rate of curving (rope sheave that diameter is little), then may causes main hoist cable exceedingly crooked, thereby influence the service life of main hoist cable.
In order to prevent above-mentioned situation, for example when to adopt diameter d be 10 millimeters main hoist cable, needing to adopt diameter D is that diameter D is the rope sheave more than 400 millimeters more than 40 times in the diameter d of main hoist cable.
Therefore, if adopt the electrical motor of external-rotor-type commonly used, because the diameter of rope sheave is 400 millimeters, so can cause the volume size of winch further to increase.
For example, when the width of counterbalanced weight is approximately 200 millimeters,, exceed the corresponding size of size partly so must the channel cross-sectional area of the horizontal direction of hoist trunk be enlarged with this because the size of winch has exceeded the size of counterbalanced weight.
In addition; Two ends at the main hoist cable that connects lift car and counterbalanced weight have the main hoist cable end that is fixed on the hoist trunk wall; Because main hoist cable end is provided with the spring that tension adjustment uses etc., so need in hoist trunk, guarantee to be provided with the required size of these springs.Therefore, winch is arranged on counterbalanced weight above the time owing to need guarantee the size that is provided with of these members, so also can cause the height dimension of hoist trunk to increase.
Summary of the invention
The present invention has carried out comprehensive research to above-mentioned problem; The object of the present invention is to provide a kind of elevator; This elevator can be limited in the component parts of elevator in the scope of specific structure and numerical value, thereby can dwindle the channel cross-sectional area of hoist trunk and the height dimension of hoist trunk.
Elevator of the present invention is characterised in that; Pulley is set respectively on lift car and counterbalanced weight; And adopt 2: 1 hoist cable winding method; The diameter d of using main hoist cable is connected lift car and counterbalanced weight with the main hoist cable with flexibility that relation between the diameter D of rope sheave satisfies D/d＜20 with rope sheave, winch is arranged on the top of counterbalanced weight, and makes winch towards the S. A. of the winch direction parallel with respect to the long limit of counterbalanced weight.
The invention effect
As stated; Owing to adopt 2: 1 hoist cable winding method; And use the relation between the diameter D of diameter d and rope sheave of main hoist cable to satisfy the main hoist cable and the rope sheave with flexibility of D/d＜20, thus can make electrical motor and rope sheave miniaturization, through this miniaturization; Can adopt the winch width to be less than or equal to the winch of counterbalanced weight width; Through upside at the actuation range of counterbalanced weight so that the parallel mode of axle of the long limit of counterbalanced weight and electrical motor, with this winch be arranged on counterbalanced weight in the drop shadow spread of upside; Can obtain thus in the channel cross-sectional area of the horizontal direction of dwindling hoist trunk, to dwindle the effect of the height dimension of hoist trunk.

The specific embodiment
First embodiment
Followingly describe with reference to the structure of accompanying drawing to the related elevator of one embodiment of the invention.At first see figures.1.and.2 and carry out explanation roughly.
In general elevator; Utilize main hoist cable 3 to connect lift car 1 and counterbalanced weight 2; Main hoist cable 3 winch 5 is set midway, carry out elevator through 5 pairs of main hoist cables of this winch, and lift car 1 and counterbalanced weight 2 in the opposite direction gone up and down up and down through this winch action.
The main hoist cable 3 of present embodiment uses 2 a pair of main hoist cables, is provided with the spring 31 that tension adjustment is used at an end 30a of main hoist cable 3, and is suspended on the beam 32 that is fixed in the hoist trunk wall.In addition, on the other end 30b of main hoist cable 3, also be provided with the spring 31 that tension adjustment is used, and be suspended in equally on the beam 32 that is fixed in the hoist trunk wall.
Being fixed with two pulleys at the top of lift car 1 is pulley 6a and pulley 6b, and lift car 1 utilizes winch 5 to go up and down.In addition, pulley 6a and pulley 6b also can be arranged on the bottom of lift car 1.
Fig. 2 representes to be arranged on the pulley 6a at lift car 1 top and the state of pulley 6b; Be respectively arranged with two guiding groove promptly main hoist cable guiding groove 12a and main hoist cable guiding groove 12b on pulley 6a and the pulley 6b, each root master hoist cable 3a, 3b are respectively through these guiding grooves 12a, 12b.In addition, each root master hoist cable 3a, 3b are directed into the rope sheave 9a and the rope sheave 9b of winch 5 after through pulley 6b.
Can know that from Fig. 1 and Fig. 2 winch 5a and winch 5b be relatively to the ground setting, rope sheave separately is that distance and the main hoist cable guiding groove 12a of pulley 6b and the interval between the main hoist cable guiding groove 12b between rope sheave 9a and the rope sheave 9b is close.Through decision like this at interval, main hoist cable 3a and the main hoist cable 3b angle when the main hoist cable guiding groove 12a of pulley 6b and main hoist cable guiding groove 12b come out diminishes, and preferred parallel has the effect in the service life that can prolong main hoist cable 3a and main hoist cable 3b thus.
This pulley 8 is installed along the long side direction of counterbalanced weight 2, in Fig. 1, is provided with the mode of the area of conter of the last side direction that is positioned at counterbalanced weight 2.That is to say that pulley 8 is installed into the long limit quadrature of its S. A. and counterbalanced weight 2.
So; 2 main hoist cable 3a, 3b are departure point with the end 30a on the beam 32 that is suspended in the hoist trunk wall; Through the pulley 6a and the pulley 6b of lift car 1, after passing pulley 6a and pulley 6b, further extend into the pulley 8 of counterbalanced weight 2 behind rope sheave 9a through winch 5 and the rope sheave 9b; Afterwards, the other end 30b of main hoist cable is suspended on the beam 32 of hoist trunk wall.
In the present embodiment; Lift car 1 is provided with pulley 6a and pulley 6b and pulley 8 as movable pulley with counterbalanced weight 2, so, with respect to the main hoist cable coiling amount of rope sheave 9a and rope sheave 9b; The amount of movement of lift car 1 is 1/2, has just constituted 2: 1 hoist cable winding-structure.
Though the amount of movement of lift car 1 is 1/2; But because the required power of elevator is compared with 1: 1 hoist cable winding method and is diminished; So can reduce by the first electrical motor 10a and the required torque of the second electrical motor 10b, can make winch 5a and winch 5b realize miniaturization.
As stated, main hoist cable 3a and main hoist cable 3b be pulley 6a and the pulley 6b through elevator car upper respectively, and one of which end and building side direct connection, and the other end is fixed on the building side after through the pulley 8 that is arranged on counterbalanced weight 2 upper surfaces.
In addition, two winchs are that winch 5a and winch 5b are controlled so as to synchronization action through not shown control setup, so can avoid lift car 1 that unnecessary vibration takes place.
At this, the required torque of the first electrical motor 10a and the second electrical motor 10b increases with the diameter of rope sheave 9a and rope sheave 9b with being directly proportional.Be specifically, along with the diameter of rope sheave 9a and rope sheave 9b increases, the length of the moment arm till the point of action that is acted on to main hoist cable 3a, 3b is elongated, thus the bigger torque of needs.Therefore, further realize miniaturization in order to make the first electrical motor 10a and the second electrical motor 10b, its precondition is to dwindle the diameter of rope sheave 9a and rope sheave 9b.
; As normally used main hoist cable in elevator; The general main hoist cable that is made up of steel wire that adopts is set at d at the diameter with main hoist cable, and the diameter of rope sheave 9a and rope sheave 9b is set under the situation of D; If adopt the main hoist cable that constitutes by steel wire, then need use the main hoist cable of D/d＞40.
About this regulation, for example in the intensity proof method of separating the traction elevator that is right of the relevant decree of building standard method and this building standard method and elevator technology benchmark, done record.
Therefore,,, the diameter of rope sheave 9a and rope sheave 9b need be dwindled, the miniaturization of the first electrical motor 10a and the second electrical motor 10b can be realized as its precondition in order to reduce by the first electrical motor 10a and the required torque of the second electrical motor 10b.And as stated,, then can't satisfy above-mentioned precondition if use the main hoist cable that constitutes by steel wire.
Therefore; In order to satisfy above-mentioned precondition; For example adopt the periphery that constitutes by thin wire to apply the high main hoist cables of flexibility such as hoist cable or banded hoist cable of synthetic resin, then can dwindle the diameter of rope sheave 9a and rope sheave 9b, make it possible to satisfy above-mentioned precondition.
That is to say; When adopting the hoist cable that constitutes by steel wire, if dwindle the diameter of rope sheave 9a and rope sheave 9b, then can cause steel wire overflexing and make the shortening in service life of hoist cable; And if use the high hoist cable of flexibility; Then overflexing situation can not take place, so even dwindle the diameter of rope sheave 9a and rope sheave 9b, can not cause shorten the service life of hoist cable yet.
For example, with the reduced 1/2 of rope sheave 9a and rope sheave 9b, then the first electrical motor 10a and the required torque of the second electrical motor 10b also can be reduced to 1/2, so can dwindle the width dimensions of winch 5a and winch 5b.
The main hoist cable that above-mentioned flexibility is high can obtain through diameter and the use high tensile steel that dwindles wire rod; Compare with the occasion of using steel wire; Even adopt the main hoist cable below the D/d=20, also can realize fatigue resistance and the long-term reliability identical with the main hoist cable of steel wire system.
As this main hoist cable with flexibility, preferably adopt main hoist cable shown in Figure 3, through adopting following structure, can obtain to have the main hoist cable 3a (3b) of flexibility.
As shown in Figure 3; 6 thin wires 30 are accumulated unit wire rod 31,6 root unit wire rods 31 are accumulated basic wire rod 32, again 5 pile foundation wire rods 32 are accumulated the main body wire rod; After this around these wire rods, carry out moulding, can access main hoist cable 3a (3b) with synthetic resin 33 with flexibility.
In the present invention, importantly realize above-mentioned precondition, and on this basis, the diameter D of employing rope sheave is the main hoist cable and the rope sheave of D/d＜20 with the ratio of the diameter d of main hoist cable.Therefore, be necessary to use hoist cable material with high flexibility.
As stated, can make electrical motor and rope sheave realize miniaturization,, can make the corresponding miniaturization of width of realization of electrical motor and rope sheave and counterbalanced weight 2 through satisfying above-mentioned precondition.That is to say, can realize that size is less than or equal to the electrical motor and the rope sheave of counterbalanced weight 2 width.
Below the method to set up of the first electrical motor 10a and the second electrical motor 10b is elaborated.
As depicted in figs. 1 and 2, the first electrical motor 10a and the second electrical motor 10b are fixed on the beam 32 of actuation range upside of counterbalanced weight 2, and the rope sheave 9a that has independently of one another of the first electrical motor 10a and the second electrical motor 10b and rope sheave 9b against each other to.And two electrical motors i.e. first electrical motor 10a and the second electrical motor 10b motor reel that is configured to the first electrical motor 10a and the second electrical motor 10b are located along the same line.
As the first electrical motor 10a and the second electrical motor 10b, can use the slim electrical motor of axial dimension, and also can use the slender type electrical motor of axial dimension greater than the Width size less than the Width size.
In the present embodiment, consider and counterbalanced weight 2 between relation, adopted the leptosomatic first electrical motor 10a and the second electrical motor 10b, just used the greatest width dimension of winch to be less than or equal to the electrical motor of the width dimensions of counterbalanced weight 2.At this moment, as stated, preferred rope sheave also has above-mentioned relation.
Use the reason of slender type electrical motor to be at this; For electrical motor is arranged on counterbalanced weight 2 in the area of conter scope of upside; Must use small-sized electrical motor; And when using small-sized electrical motor,, then can in miniaturization, obtain big as far as possible torque if use the slender type electrical motor.
According to said structure; Upside through at the actuation range of counterbalanced weight 2 is provided with winch 5a and winch 5b; And with winch 5a and winch 5b be arranged on counterbalanced weight 2 in the area of conter scope of upside; Can avoid lift car 1 and winch 5a and winch 5b in the same cross section of hoist trunk, to interfere, thereby can dwindle the sectional area of hoist trunk.That is to say, owing to can winch 5 be arranged in the area of conter scope of actuation range of counterbalanced weight 2, so can dwindle the sectional area of hoist trunk.
In addition, owing to can winch 5a and winch 5b be arranged on the side of lift car 1, and need not be arranged on the top of lift car 1, so can dwindle the top of lift car 1 and the gap between the hoist trunk top.That is to say, because the top of lift car 1 does not exist winch 5a and winch 5b, so can correspondingly shorten the height of hoist trunk.
And; Through make rope sheave 9a and rope sheave 9b relatively to; Can further dwindle main hoist cable 3a and main hoist cable 3b distance each other; Thereby the angle in the time of can making winner's hoist cable below rope sheave 9a and rope sheave 9b, get into counterbalanced weight 2 diminishes, and helps to prolong the service life of main hoist cable 3a and main hoist cable 3b thus.
In addition; Can impartially divide when ceding territory to be arranged on rope sheave 9a and the rope sheave 9b at total radical of main hoist cable; For example when main hoist cable 3a and main hoist cable 3b are made up of 2 main hoist cables respectively; Total radical of main hoist cable is 4, and when winch 5 is made up of winch 5a and two of winch 5b, 2 hoist cables of reeling respectively on each rope sheave 9a and the rope sheave 9b.Therefore, the sum of winch 5 and main hoist cable is preferably even number respectively.
Structure according to above-mentioned present embodiment; Compare with the occasion of using a rope sheave to suspend all hoist cables in midair; The suspension load that acts on the motor reel reduces half, so the framework realization miniaturization that can make the axle of the first electrical motor 10a and the second electrical motor 10b and support these.
The quantity of winch 5 is not limited in two of present embodiment, also can use the winch 5 more than three, certainly, when the quantity of hoist cable is 8, also can use 4 winchs.
As stated; Owing to adopt 2: 1 hoist cable winding method; And use the relation between the diameter D of diameter d and rope sheave of main hoist cable to satisfy the main hoist cable and the rope sheave with flexibility of D/d＜20, thus can make electrical motor and rope sheave miniaturization, through this miniaturization; Can adopt the winch width to be less than or equal to the winch of counterbalanced weight width; Through upside at the actuation range of counterbalanced weight so that the parallel mode of axle of the long limit of counterbalanced weight and electrical motor, with this winch be arranged on counterbalanced weight in the drop shadow spread of upside; Can obtain thus in the channel cross-sectional area of the horizontal direction of dwindling hoist trunk, to dwindle the effect of the height dimension of hoist trunk.
Second embodiment
Followingly the related elevator of other embodiments of the invention is elaborated with reference to Fig. 4.Be that with the difference of embodiment shown in Figure 2 in the present embodiment, the pulley 6a and the pulley 6b that are arranged in the pulley 6 at top of lift car 1 form one group, and spaced apart to be provided with another group pulley be pulley 6c and pulley 6d.
In addition, the rope sheave 9a of winch 5a and winch 5b and rope sheave 9b are also to be arranged on the beam 32 mode that should the predetermined distance devices spaced apart.
Main hoist cable 3a is through pulley 6a and pulley 6b, and main hoist cable 3b is through pulley 6c and pulley 6d, and main hoist cable 3a and main hoist cable 3b are wound on the rope sheave 9a and rope sheave 9b of winch 5a and winch 5b.
According to said structure; Can set the interval between main hoist cable 3a and the main hoist cable 3b wideer, can obtain thus to improve lift car 1 suspention stability effect, reduce the effect of the danger that main hoist cable 3a and main hoist cable 3b be intertwined and make main hoist cable 3a and main hoist cable 3b successfully gets in the guiding groove of each pulley and at least a effect in the effect that can increase the service life.
In the present embodiment, the pulley 6 of lift car 1 is provided with 2 pairs, and the pulley 8 that is arranged on the counterbalanced weight 2 also can use 2 pulleys with each pulley of lift car 1 accordingly.
The 3rd embodiment
Followingly the winch 5a on the related hoist trunk top of another other embodiment of the present invention and the example that is provided with of winch 5b are described with reference to Fig. 5 and Fig. 6.
At Fig. 1 to the embodiment shown in Figure 3, winch 5a and winch 5b against each other to state under be fixed on the beam 32, so the axial length addition of winch 5a and winch 5b makes that the horizontal length of winch 5 is elongated.
Relative therewith, present embodiment is characterised in that and has proposed a kind of structure of dwindling the lateral length (axial length) of winch 5, in order to shorten the axial overall length dimension L of winch 5 single-pieces, is arranged on the short transverse winch 5a and winch 5b overlapping.
Two winchs are that winch 5a and winch 5b are arranged in the motor reel specified amount that upwards staggers; The rope sheave 9b that is positioned at the second electrical motor 10b of below compares with the rope sheave 9a of the first electrical motor 10a that is positioned at the top; Axially staggering apart from S; Thus, can not hinder the main hoist cable on the rope sheave 9a that is wound up into the first electrical motor 10b to pass through.
After this, the pedestal 24b that is provided with that the pedestal 24a and the second electrical motor 10b are set with the first electrical motor 10a combines through transom 23, across vibration-proof rubber 25 winch 5a and winch 5b is fixed on the winch pedestal 26 at last.
The purpose that vibration-proof rubber is set is for the solid-borne sound that prevents winch 5a and winch 5b (Solid Borne Sound) is delivered to contiguous room, and reduces the vibration of lift car 1.According to present embodiment; There is no need vibration-proof rubber 25 to be set on the pedestal 24b respectively being provided with of the pedestal 24a and the second electrical motor 10b that be provided with of the first electrical motor 10a; Therefore number of components and parts can be reduced, the length of the short transverse of winch 5a and winch 5b can be dwindled.
Occasion at present embodiment; Need be on short transverse overlapping winch 5a and the required space of winch 5b of being provided with; But through making lift car 1 lightweight; Can realize the lightweight (can reduce the stacked blocks number of counterbalanced weight) of counterbalanced weight 2, its result can be in top belay overlapping winch 5a and required space of winch 5b of being provided with on short transverse of counterbalanced weight 2.
That uses in an embodiment of the present invention is coated and main hoist cable with the use steel wire in the main hoist cable of flexibility and the technology is formerly compared by synthetic resin 33, can improve friction coefficient.So, realized under the weight-saving situation that at lift car 1 the main hoist cable of being processed by steel wire skids easily, therefore, to compare with the main hoist cable of processing by steel wire, the main hoist cable that has been carried out coating by synthetic resin 33 is more favourable.
At two electrical motors is on the first electrical motor 10a and the second electrical motor 10b, is provided with in the position with rope sheave 9a and rope sheave 9b opposition side and is fixed on brake disc or stop mechanism 21a and the stop mechanism 21b of brake wheel to brake that pushes rotation on the motor reel and through brake shoe.
The purpose of stop mechanism 21a and stop mechanism 21b is when lift car 1 rests on the floor of regulation, to stop lift car 1 to go up and down; Because fault or brake shoe have appearred in a side in stop mechanism 21a and stop mechanism 21b when the situation of abnormal wear has taken place; The opposing party's stop mechanism still can play a role, so can prevent lift car 1 action and the speed rising that suppresses lift car 1.
These stop mechanisms are installed on the first electrical motor 10a or the second electrical motor 10b, more for a long time, through the drg (not shown) of dual system is set, can on each electrical motor, stop mechanism be installed on lift car 1 in the quantity of electrical motor.

And main hoist cable 3a and main hoist cable 3b are wound on the rope sheave 9a and rope sheave 9b on counterbalanced weight 2 tops, and are fixed to the building side.
In addition, winch 5a and winch 5b are fixed on the not shown beam (beam 32 shown in Figure 1), and this beam is used to connect guide rail 13a and the guide rail 13b to the walking channeling conduct of counterbalanced weight 2.
In the occasion of common elevator, be processed to form the diameter d that at the interval of guiding groove 12a on pulley 6a and the pulley 6b and guiding groove 12b W size equals main hoist cable and add the value that obtains after the permission oscillating quantity of main hoist cable 3a and main hoist cable 3b.
According to present embodiment; Can interval W be set for the diameter d of main hoist cable and compare enough greatly; For example be set at more than 2 times of diameter d of main hoist cable, so that the incident angle of the pulley 6a on lift car 1 top and pulley 6b and rope sheave 9a and rope sheave 9b becomes minimum.
Thus, the friction on the surface of main hoist cable 3a and main hoist cable 3b can be suppressed, the vibration of lift car 1 can be suppressed simultaneously.
In addition, according to present embodiment, it is winch 5a and winch 5b that winch 5 has two winchs.So, just in case when wherein fault has taken place in a winch, the non-equilibrium state of the load between monitoring lift car 1 and the counterbalanced weight 2, and lift car is risen or descend through remaining winch.
As the confirmation method of non-equilibrium state, for example can use the load detecting appearance of lift car 1 to confirm, perhaps also can confirm through detecting hoist cable tension force and motor torque, therefore, can use above-mentioned any method to confirm.
In addition, when fault has taken place a side winch, all compare in the occasion of normal operation with 2 winchs, total torque reduces.If repair time is shorter, then can adopt the close torque of maximum torque with normal winch to make the lift car low speed elevation.
