Description
The present invention relates to elevator device, particularly relate to the tension element of this elevator device.
Traditional traction elevator system comprises a car, a counterweight, and two or many connect the ropes of car and counterweight, and one is used for pulley that these ropes are moved and the motor that hauling block is rotated.These ropes are twisted with the fingers or are twisted into by steel wire, and pulley is made by cast iron.
Although common steel cable and cast iron pulley have been proved to be very reliable and expense is reasonable, their application still is limited.A kind of such tractive force that is limited between rope and the pulley.The common technology that increases tractive force between rope and the pulley causes the durability of rope to reduce, increase the pressure of wearing and tearing or increase rope.
Another that uses this steel cable is limited in the flexibility and the fatigue characteristic of steel rope.The minimum diameter of steel cable is mainly stipulated by tired demand, thereby has been caused thicker rope relatively.This cross-sectional plane thicker rope has relatively reduced its intrinsic flexibility, forces pulley to have a relatively large diameter.The diameter of pulley is big more, and it is just big more to drive the required moment of torsion from motor of elevator device, thereby has increased the size and the expense of elevator device.
Another defective of common round rope is the pressure that less diameter of pulley will increase rope, shortens the life-span of rope.Rope pressure produces when rope is crossed pulley, and is directly proportional with tension force on the rope, and is inversely proportional to diameter of pulley D and rope diameter.In addition, the shape of pulley groove comprises the tractive force increase technology of this pulley groove of intaglio having increased the maximum rope pressure that rope is born again.
In the lift facility that a kind of representative type rope drives, the wedge shape clip is as terminating set.Work between the streamline contour chock that the wall with relative angle and of this wedge shape clip by elevator rope being fixed on the wedge shape clip centered on by steel cable.In the tensioning process of rope, this chock effect is resisted against on the wall of wedge shape clip rope.This design-calculated benefit is that chock can have a relatively sharp angle and produce a bigger Clamping force.Because steel cable has high compression-strength, this bigger Clamping force can not produce such as deleterious effects such as crushing or creeps rope.
In the deficiency of attempting to overcome the smooth bar cable that is used for elevator device and the effort of defective, develop to some extent for the coating tension element that comprises a relatively more flat tension element.This flat tension element comprises the single ropeway carrying-rope in a plurality of embedding one common coats.This representative type tension element that the application considers is at the U.S. NO.09/031 of application on February 26th, 1998, in divide an application " tension element of elevator " that is entitled as " tension element of elevator " for No. 108 and December 22 applied for by AttorneyDockeyt1998 more detailed description is arranged, these two pieces of documents will be here by with reference to and incorporated.
This coat around and/or separate these single ropes, and and form one and be used for the composition surface that engages with hauling block.The tension element of this structure makes the pressure of rope can pass through the more uniform distribution of tension element, and tractive force increases and all is possible than the pulley of minor diameter.
This flat tension element connected and the method on the termination of being fixed on comprises this element ring is clamped the end on a bar and with pair of plates.This flat board passes the fastener that is arranged on the hole on this flat board by one group and is fixed.Another method that this flat tension element is connected on the termination comprises a tapered end fastener, and wherein wedge of material is positioned at the end of tension element and is clamped by pair of plates.In this structure, one flat plate has the wedge-shaped cross-section that matches with wedge of material, and another piece flat board has the cross-sectional plane of same thickness.Similarly, this passes the fastener that is arranged on the hole on the flat board to flat board by one group and fixes.The shortcoming of this terminal connection method is that the Clamping force that is provided by fastener only is provided the tension force ability to take the burden of this terminal.In addition, this wedge fasteners has limited the ending point of element, has pind down adjustable.
Top technology can not stand the test, and the scientists and engineers continues research and develops the more effective and durable method and apparatus that drives elevator device under the procuratorial guiding of the application.
According to the present invention, the terminating set that is used to have compressible external coating tension element comprises a chock, and it is arranged in the socket with the clamping surface that cooperatively interacts.Cable loop is around chock and insert this socket, and is clamped by the tensioning of element and the power that cooperation produced of chock and clamping surface there.
Most important characteristic of the present invention is the angle of the shape of chock, particularly chock, comprises its length and width.This chock is determined size, the chosen slip of angle to provide enough Clamping forces to offset rope, and can be above the compressing stress ability of tension element.In addition, this chock comprises the tension force a when semi-circular top distributes rope to cross over chock effectively.

In Fig. 1, shown a traction elevator system 12.This elevator device 12 comprises car 14, counterweight 16, traction drive part 18 and motor 20.This traction drive part 18 comprises the tension element 22 and the hauling block 24 that connect car 14 and counterweight 16.This tension element 22 and pulley 24 engagements make pulley 24 rotate mobile tension element 22, thus mobile car 14 and counterweight 16.Tension element 22 joins by terminal clip 30 and counterweight 16 and car 14.Although what show is a gear motor 20, should be noted that this structure is not only shown form, the present invention can use gear or non-gear motor, in addition, although what show is a relative more flat tension element 22, should note this also mode of an example just equally, the present invention can use the tension element of other form that comprises circular coated tension element etc.
An embodiment of terminal clip 30 is shown in more detail among Fig. 2.Tension element 22 is twining chock 32 and is being positioned at socket 34.Terminal clip 30 is connected with counterweight 16 with car 14 by pipe link 36, and this pipe link 36 utilizes pin 38 to be connected on the socket 34.Pipe link 36 is by being screwed into nut 40 also with spring cotter 42 fixing being connected on car 14 and the counterweight 16.Also show a kind of additional clamping plate clip 50 among Fig. 2, wherein tension element 22 is sandwiched in the groove 52,54 of plate 56,58 in a kind of mode of double-deck lapping.
Referring to Fig. 3, clip 30 is used to provide the security terminal of a tension element.In use, the leader of tension element 22 44 inserts the perforate 46 that is arranged in socket 34 bottoms, as shown in FIG., tension element around part 47 round chock 32, afterbody 48 passes from perforate 46 again then.Chock 32 inserts in the opening 60 of sockets 34, obtains clamped position as shown in Figure 2, and leader 44 wherein and afterbody 48 are clipped in 62,64 of the clamping surfaces of socket 34 respectively.Terminal clip 30 is designed so that tension element 22 and the alignment of pipe link 36 substantial axial, to obtain the rotation that actv. load transfer and control produce undesirable terminal clip.
Still with reference to Fig. 3, in service usually at elevator device 12 (Fig. 1), the tension force (T) in tension element 22 leaders 44 is the direction shown in the arrow 66, its makes impels chock 32 to enter socket 34 more to perforate 46 directions around part 47.Along with the load of tension element 22 makes chock 32 enter socket 34, the Clamping force of arrow 68 representatives is clamped leader 44, and it is resisted against on the clamping surface 62, and the Clamping force of arrow 70 representatives is clamped afterbody 48, and it is resisted against on the clamping surface 64.Clamping force 68,70 is perpendicular with jaw 62,64 respectively, and perpendicular to the various piece of chock 32, and it is with normal force (Fn) expression.Offset tension force (T) in the tension element 22 by jaw 62,64 Clamping forces that produced with acting on friction force on the part 47, thereby this element is remained in the clip 30.
The another kind of embodiment of terminal clip 30 is presented among Fig. 4 and Fig. 5, and pipe link 36 wherein is connected on the pivot body 72 by pin 38, and pivot body 72 utilizes pivot pin 74 pivotally to be connected on the socket 34 conversely again, and fixing with spring cotter 76.In this special embodiment, the leader of tension element 22 44 inserts the perforate 46 that is arranged in socket 34 bottoms, as shown in FIG., tension element around part 47 round chock 32, afterbody 48 passes from perforate 46 again.Chock 32 is inserted in the opening 60 of socket 34 then, obtains clamped position shown in Figure 5, leader 44 wherein and afterbody 48 are clamped at 62,64 of the clamping surfaces of socket 34 respectively.In case the key character of this embodiment is that chock 32 and tension element 22 are installed in the socket 34, pivot body 72 then is mounted, to prevent if the tension force in the element reduces and cause the chock of not noted to skid off from socket.In addition, this special embodiment keeps tension element 22 and pipe link 36 to align coaxially basically to obtain the actv. load transfer.Pivot body 72 also can be so that tension element 22 produces an angle displacement with respect to car 14 or counterweight 16, and can not produce big stress in pipe link 36 or socket 34.This special embodiment is better than Fig. 2 and another advantage embodiment illustrated in fig. 3 is, causes the bottom-to-top-height of socket to reduce because chock 32 inserts by the top of socket 34.Then pivot body 72 is inserted also close this chock, thereby reduced the bottom-to-top-height of terminal clip 30.
The shape of chock 32 is to produce normal force 68,70 and the correct key factor that keeps tension element 22.The related parameter that has of the chock 32 of control normal force Fn as shown in Figure 6 comprises the length (L) of 78 representatives, the degree of depth (d) of 80 representatives, and 33,35 the angle φ from line of centers 83 to clamping surface of 82 representatives and the width (W) of tension element 22 are (Fig. 2).Tension force (T) in the tension elements 22 that another parameter relevant with control normal force 68,70 is 66 representatives.Parameter L and d are fixed against φ slightly, but limited by the free space of hoistway (not shown).The tension force T of a given name, normal force Fn68,70 (Fig. 3 and Fig. 5) is relevant with angle φ again conversely.That is to say that if φ is too little, Fn is with excessive, tension element 22 will experience compression creep.What be even more important in one embodiment a bit is that tension element 22 includes the outer coat of a urethane, perhaps be coated with another kind of flexible resilient part, this is because they have the maximal compressed stress (σ that is about 5MPa before producing expendable distortion or creep
c).On the other hand, if if φ is too big, normal force is with too small, and tension element will slide in terminal clip 30.Its biggest advantage is the compressing stress that reduces on the tension element 22.A kind of method that reduces compressing stress is the length L that increases the Clamping force effect, but considers hoistway and limited this respect.Consider above-mentioned physical parameter, for fear of surpassing σ
c, minimum φ can be pre-determined by following formula:
φ=tan
-1[T/(σ
c *L
*W)]
In a typical case of the present invention used, tension element had the tension force T of about 2500N, and d is about 60mm to 70mm, and L is about 140mm, and φ is about 9 and spends to 10 degree.
With the special example that is presented at the terminal clip 30 among Fig. 4 and Fig. 5 the present invention is described referring now to Fig. 6.A representative type tension element 22, described in above-mentioned related application, by having the outer coat of urethane and having 30, the wide flat flexible rope of the 30mm of the maximum tension of 000N constitutes.As is known in the art, the safety factor of elevator rope is approximately 12, thereby the maximum tension that offers tension element 22 is approximately 2500N.Length L is that 140mm and angle φ are that 10 chocks 32 of spending obtain size d according to following formula:
d=2(Ltanφ)=2(140tan20/2))=49.37mm
Equal 2500N with T and come following definite Fn:
Fn=T/sinφ=2500/sin(20/2)=14,397N
Because Fn is distributed on the whole area of leader 44, so the stress in compression sigma of tension element 22 is leader area A, promptly is clipped in the function of area at clamping surface 32 places of chock 32, and this area can followingly calculate:
A=L*w=140*30=4,200mm
2
Compressing stress in the tension element 22 can followingly be determined:
σ=Fn/A=14,397/4,200=3.43MPa
In this special example, the compressing stress of material does not go beyond the limit, and therefore can not produce creep.
It is extremely important that terminal clip 30 is offset the ability of the T on the leaders 44, and it is the function of the friction coefficient (μ) between Fn and tension element 22 and clamping surface, chock 32 surfaces.In the example of being given, tension element 22 comprises a urethane coat, and clamping surface 62 and chock 32 all are smooth steel parts, and the conservative value of friction coefficient is μ=0.25 approximately between these surfaces.In order correctly chock 32 to be remained in the socket 34, T must offset the tension force in the leader 44 basically, and remainder can be delivered to around part 47.Following relation of plane has provided the maximum low power Fr that disappears from the principle aspect that clamps, or the amount of the tension force that can be cancelled, in the example of the μ that provides=0.25:
Fr=μ*Fn=0.25*14,397=3,599N
Therefore, recall in example the maximum T of given 2500N, all the tension force T in tension element 22 leaders 44 will be cancelled, so element can not slide in terminal clip 30.
Another embodiment of the present invention is included in a rough surface on jaw and the chock, its purpose is to improve the friction coefficient between tension element 22 and clamping surface 62,64 and the chock 32.In a special embodiment, this surface makes its roughening by the process of sandblasting.Sandblast friction coefficient brought up to 0.35 or bigger in the surface.The method that increases skin friction force comprises etching, machinework, annular knurl and other suitable similar approach.Except increasing friction coefficient, will form little protuberance and low ebb on the surface of this roughening.A characteristic of urethane coat is to be tending towards presenting cold flow under high load condition.Under above-mentioned condition of loading, urethane coat cold flow enter and in chock and socket around the protuberance and low ebb, be also referred to as lock-in feature, it provides little but actv. mechanical caging, and this lock-in feature has increased the ability that terminal clip opposing tension element 22 slides.Lock-in feature in the scope of the invention can comprise groove, striped 83 (Fig. 7), otch, diamond pattern or other suitable forms.It should be noted that these lock-in features have reduced required normal force recited above.Use described lock-in feature can reduce length L, perhaps increase angle φ the danger that creep takes place is minimized.
Another embodiment that has shown chock 32 among Fig. 7, it is included in the protuberance 84,86 that is formed with passage 88 therebetween.Protuberance 84,86 height near rope in tension element 22 coats.For example, the tension element 22 among special embodiment is that 3mm is thick, and it has the high rope of 1.4mm that is arranged at wherein. Protuberance 84,86 in this specific embodiments is approximately the dark passage of 1mm 88 with formation.Tension element 22 is positioned at passage 88, and chock 32 is installed in the socket 34 as mentioned above.The benefit of protuberance 84,86 is that they are contained in the tension element 22 that the coat material has given expectation cold flow characteristic in the passage 88, in addition, protuberance 84,86 determines that by the displacement of restriction chock 32 in socket 34 size prevents that the compressing stress of tension element 22 lost efficacy.Just in case being delivered to swell in the element, power greater than expection normal force Fn 84,86 will contact and stop chock 32 mobile in socket 64 with clamping surface 62,64.
Referring now to Fig. 2,8 and 9 the available tensioning clip 50 that together uses with terminal clip 30 above-mentioned is described.The purpose of this tensioning clip 50 is the tension force that helps in termination and the counteracting element 22, makes the tension force between leader 44 and the afterbody 48 equal the tension force that they enter socket 34 places.Tensioning clip 50 also helps terminal clamp 30 to reduce stretch-draw when undesirable accident takes place tension element 22, as, in the process that lift car 14 stops suddenly, assist terminal clip 30.Tensioning clip 50 was just clamped them before afterbody 48 and leader 44 enter socket 34.When with tension element 22 engagements, tensioning clip 50 can not move. Plate 56,58 is shown in the figure and be identical in description, but within the scope of the invention, and this two boards can change into wherein that a plate has the tension element groove, and another piece plate does not have groove.
As mentioned above, tensioning clip 50 comprises a pair of plate 56,58, and they include a tension element groove 52,54 near tension element 22 thickness.Plate is provided with the boring 51 that is used to pass fastener 53. Plate 56,58 also comprises having a guide edge 55 than long radius, is beneficial to leader 44 and afterbody 48 enters seamlessly transitting of tensioning clip 50 from socket 34.
In use, leader 44 inserts in the groove 52 of plate 56, and afterbody 48 inserts in the groove 54 of plate 58, and this two boards is assembled together with fastener 53.When bolt 53 was tightened, tension element 22 was sandwiched in the groove 52,54, and clamped by plate 56,58 and to resist slip.In this way, prevented tension element moving with respect to tensioning clip 50.
When additional tensioning clip 50 used with terminal clip 30, leader 44 and afterbody 48 were shared whole tension force that car 14 produces.Consider this point, be used for determining that analysis that above institute has set up the clamping characteristic will be modified to reflects that tension force shares a load on every hawser.
Though shown and described illustrated embodiments, can make various modifications without departing from the spirit and scope of the present invention and substitute.Therefore, should understand that the present invention describes in the mode of example, but be not limited to this.
