First end 24 of ropes 22 is fixed on the building member 14, and ropes 22 drives with drive pulley 30 engagements and by elevator main 32 then.Then rope 22 is walked around deflection sheave 34.Respectively as illustrated in fig. 1 and 2, rope 22 can be reeled separately or bifilar coiling deflection sheave and drive pulley 34,30.The advantage of bifilar coiling is still less to provide additional tractive force to elevator device 10 under the worn-down situation.Then rope 22 is walked around idle pulley 36, and described idle pulley 36 directly or indirectly is installed on the building member 14.Then, rope 22 is walked around idle pulley 38 belows that are arranged on counterweight 20 places, and then ends at second rope end, 26 places that are installed on the building member 14.
During work, lift car 16 promotes certainly by hoistway 12 under the effect of ropes 22, and ropes 22 provides tractive force and suspension force.When the described drive pulley 30 of elevator main 32 drivings was rotated, rope 22 ordered about lift car 16 and replace vertical shifting up and down with counterweight 20 in hoistway 12.Therefore, embodiments of the invention do not need to be used for the machine room of elevator device 10.In the preferred embodiment of this structure, adopt flat ropes to provide additional tractive force and permission to adopt littler pulley and elevator main.A this example that can flat ropes used in this invention is that sequence number in application on February 26th, 1998 is 09/031,108, be entitled as the rope described in the unsettled together U.S. Patent application of " stretching element that is used for elevator ", the document is feared at this for your guidance.Adopt less main frame not only can reduce the expense of system 10, can also reduce the size and the weight of elevator main, thereby elevator main 32 and lift car 16 can be made one.In addition, adopt ropes 22 can also reduce by two groups of ropes with stretching and suspension effect.
Referring to Fig. 3, alternative embodiment of the present invention has been represented a Machineroom-less elevator system 110, and this system 110 has a lift car 116 that is advanced by the elevator main of installing 132 thereon.Main frame 132 drives one and is installed on the main frame 132 or built in wherein drive pulley 130.Elevator device 110 also comprises a deflection sheave 134 and a plurality of idle pulley 135-141.Idle pulley 135,136 is fixedly mounted on the lift car 116, and idle pulley 139,141 is installed on the counterweight 120.Idle pulley 137,138,140 directly or indirectly is installed on the building member 114.Ropes end 124,126 also directly or indirectly is fixed on the building member 114.At first, ropes 122 is walked around idle pulley 135,136, walks around idle pulley 137 then.Then, rope 122 is wound on drive pulley and the deflection sheave 130,134.Then, rope 122 is respectively by idle pulley 138,139,140,141 guiding.Shown in Fig. 3 and 4, rope 122 can be reeled separately or bifilar being wound on deflection sheave and the drive pulley respectively.
During work, elevator main 132 drives described drive pulley 130 and rotates, and described drive pulley 130 drives rope 122, thereby advances lift car 116 in hoistway 112.This Abseiling device has the advantage beyond the first embodiment of the invention.This Abseiling device provides the ratio of drive pulley speed with the elevator car speed of three to one (3: 1), adopts littler main frame thereby reduced required moment and the permission of elevator main.Further reducing of this elevator main size is that elevator device is very expected, this means that the requisite space of main frame and weight and expense can further reduce.
Referring to Fig. 5 and 6, in another alternative embodiment of the present invention, Machineroom-less elevator system 210 comprises lift car 216 and the counterweight 220 that is hung by ropes 222.Rope 222 comprises first cable end 224 and second cable end 226 that is fixed on the counterweight 220 that is fixed on the lift car 216.The rope 222 that is driven by elevator main 232 passes drive pulley 230.Elevator main 232 and drive pulley 230 are installed on the lift car 216.A deflection sheave 234 also is installed on the lift car 216.A plurality of idle pulley 235-238 are arranged in the hoistway 212.Idle pulley 235,236,238 directly or indirectly is fixed on hoistway 212 tops of building member 214, and idle pulley 237 directly or indirectly is fixed on hoistway 212 bottoms of building member 214.In lift car 216, be shaped on turnover plate 250, with can be near elevator main 232.
The end 224 of ropes 222 at first is installed on the lift car 216, and rope 222 is walked around idle pulley 235,236 respectively then, then walks around to turn to and drive pulley 234,230.Next, rope 222 is walked around idle pulley 237,238 and is directed to, and ends at counterweight 220 then.This Abseiling device provides the ratio of drive pulley speed with the elevator car speed of two-to-one (2: 1), adopts littler main frame thereby reduced required moment and the permission of elevator main.
Another advantage of the present invention is that the elevator main that is installed on the lift car described here can provide comparatively safe environment for service personnel.Can operate elevator main by the turnover plate that it provides from the inside of lift car.
Principal character of the present invention is that the rope that adopts in above-mentioned elevator device is flat.Its width can cause rope to have a mating surface that is limited by width " W " with the increase of gauge ratio, promptly helps carrying the pressure of described rope.Therefore, the maximum rope pressure in the rope has reduced.In addition, than the circular rope that is 1, by improving the size ratio, the thickness of flat ropes (see figure 7) " t1 " can be reduced with respect to size, still keeps being used in the rope support the rope constant cross-sectional area partly of tension load simultaneously.
Shown in Fig. 7 and 8, flat ropes 722 comprises a plurality of independent bearing core wires 726, and these heart yearns are enclosed in the same overplate 728.Overplate 728 separates each heart yearn 726 and has determined to be used for and hauling block 724 ingear mating surfaces 730.Bearing core wires 726 can be made by high-intensity lightweight non-metallic material, and for example aramid fibre is perhaps made by metallic material, for example thin high-carbon steel fiber.Expectation makes the thickness " d " of heart yearn 726 as far as possible little, to increase alerting ability and to reduce the stress of heart yearn 726.In addition, for the heart yearn of being made by steel fiber, fibre diameter should be less than 0.25 millimeter, and preferably diameter is in about 0.10 millimeter to 0.20 millimeter scope.Steel fiber with this diameter can improve the alerting ability of heart yearn and rope.The heart yearn of making by the material that will have this weight, intensity, life-span, especially above-mentioned alerting ability characteristic is in flat ropes, and traction sheave diameter " D " can reduce, and still can remain in the maximum rope pressure that can accept in the limit simultaneously.
Mating surface 730 contacts with the corresponding surface 750 of hauling block 724.Overplate 728 is by polyurethane material, and preferably thermoplastics type's urethanes is made, and many heart yearns 726 are extruded and passed to this material in the following manner, and promptly each independent heart yearn 726 all is carried out restriction and can not be along the longitudinal movement with respect to other heart yearns 726.For overplate, if there is other materials to be enough to satisfy tectal required function, promptly draw, wear and tear, to the load of heart yearn transmitting tractive and overcome environmental factor etc., also can adopt these materials.Should be understood that,,, then adopt flat ropes and the favourable aspect that has will reduce if they can not satisfy or surpass the mechanical characteristics of thermoplastics type's urethanes although can adopt other materials for overplate.According to the mechanical characteristics of thermoplastics type's urethanes, the diameter of hauling block 724 can be reduced to 100 millimeters or littler.
The result of structure flat ropes 722 is like this, and rope pressure can distribute more equably by rope 722.Because many little heart yearns 726 in flat ropes resilient coating 728, are then compared with the rope of prior art, the pressure on every heart yearn 726 has obviously reduced.Heart yearn pressure is reduced by at least n -1/2, wherein n is for giving fixed load and steel wire cross-sectional area, the number of parallel heart yearn in the flat ropes.Therefore, compare with the traditional rope elevator with less load-carrying capacity, maximum rope pressure has obviously reduced in the flat ropes.In addition, for identical load-carrying capacity, effectively rope diameter ' d ' (measuring at bending direction) has reduced, and is not reducing under the D/d ratiometric situation, and diameter of pulley ' D ' is kept than fractional value.In addition owing to reduced diameter of pulley D, just can adopt at a low price with more compact high-speed electric expreess locomotive as driving host.
Fig. 7 has also represented the sort of hauling block with traction surface 750 724 that is configured to hold flat ropes 722.Mating surface 750 be constructed to be permeable to provide tractive force and guide flat ropes 722 and pulley 724 between the form of engagement.Hauling block 724 comprises a pair of flange 744 and the one or more dividing plate 745 that is arranged between the adjacent flat rope that is arranged on pulley 724 both sides.Hauling block 724 also comprises the lining 742 that is contained between flange 744 and the dividing plate 745.Lining 742 defines mating surface 750, makes to form lateral clearance 754 between the both sides of flat ropes 722 and lining 742.Double-type flange 744 and dividing plate are realized function that flat ropes 722 is guided with lining, produce tangible inconsistent phenomenon to prevent rope under the state lax the grade.Although graphic display unit comprises lining, should be understood that, also can adopt the not hauling block of belt material cover.
Although with reference to specific embodiment performance with described the present invention, for a person skilled in the art, should this understand that without departing from the spirit and scope of the present invention, the present invention can make various deformation.For example, the position of drive pulley and deflection sheave can exchange.In addition, although graphic elevator main 32,132 is positioned at lift car 16,116 belows, they also can be installed in side, top or any other position of lift car.Similarly, the position of elevator main 232 also can change.
