Detailed description of preferred embodiment
Referring to Fig. 1-2, implement elevator device of the present invention and generally indicate with label 10.This elevator device comprises a hoistway 12 that is limited by surrounding structure 14.A lift car 16 is positioned at hoistway 12, is used for carrying out up-and-down movement along hoistway.First and second elevator pulleys 20,22 are connected the below of lift car 16 and are positioned at relative both sides.Elevator device 10 comprises first and second support columns 24 and 26, and they are arranged on the side 28 of lift car 16, and generally is positioned at opposite side 30,32 places of hoistway 12.First and second pillar stiffeners 24,26 are from the bottom or the base plate 34 of hoistway 12 extends to hoistway along vertical bearing of trend top.Supporting member 36 (being represented by dotted lines among Fig. 1) is installed in hoistway 12 tops and the general horizontal direction between first and second pillar stiffeners 24,26 is extended.
CD-ROM drive motor 42 is supported on the supporting member 36 and is positioned at vertically extending space, described CD-ROM drive motor comprises a drive pulley that links to each other with drive motor 44, and along aliging in the hoistway 12 vertically extending spaces, this space is between lift car 16 and hoistway wall 46.
Elevator device 10 also comprises a counterweight 48, and this counterweight 48 has a counterweight pulley 50 that is connected the counterweight top.Counterweight 48 is suitable for being positioned at CD-ROM drive motor 42 belows and the CD-ROM drive motor 42 of preferably aliging, and described CD-ROM drive motor 42 is positioned at the vertical extent space, and described space is along hoistway 12 extensions and between lift car 16 and sidewall 46.Counterweight 48 links to each other with lift car 16 by a flat ropes or band, is used at lift car along hoistway 12 balance lift car vertically the time.
With respect to the drive motor and the pulley that use traditional circular rope, adopt flat ropes or belt just can drive and hang lift car and counterweight load with less drive motor and pulley.Since rope through repeatedly crooked with stretch after can produce fatigue, so the diameter of the drive pulley of using on the elevator that has traditional circular rope is restricted to 40 times bigger of rope diameter.Flat ropes or belt have the size ratio greater than 1, said here size than the ratio of the width w that is defined as rope or band and thickness t (size than=w/t).Therefore, with respect to traditional circular rope, flat ropes or band itself is just thinner.Because rope approaches, so when this rope or belt were walked around the pulley of a given diameter, intrastitial flexure stress was less.So just can use hauling block than minor diameter.Torque is directly proportional with the diameter of hauling block.Therefore, use the torque that can reduce motor than the hauling block of minor diameter.The size of motor (volume of rotor) roughly is directly proportional with torque, therefore, though no matter the much mechanical horsepower outputs of the size of pulley keep constant, but with respect to the elevator device that uses traditional circular rope, flat ropes or belt make this system can use less drive motor to come with higher speed operation.Therefore, less traditional flat drive motor can be placed in the hoistway between lift car and the hoistway wall, and this has reduced size and its fabrication cost of hoistway significantly.
In a word, the size (that is the size of drive motor and pulley) that reduces machine has many advantages.At first, when machine was placed on the top of lift car and hoistway wall, less machine had reduced the demand to hoistway space.The second, the used material of small machine is few, thereby its manufacturing cost is lower with respect to bigger machine.The 3rd, small machine in light weight, this has just reduced the time that is used for handling machine, and has reduced and be used for machine is promoted the devices needed that puts in place, thereby has reduced erected cost significantly.The 4th, low torque and the high-speed characteristic system that makes can save expensive gear.Furtherly, gear can cause vibration and noise, and need be lubricated maintenance.But if desired, the machine that has gear also is operable.
With respect to circular rope, the load distribution that flat ropes or belt also make elevator and counterweight on the pulley than large tracts of land on, to reduce the specified pressure on the rope, this has just prolonged the service life of rope.Again furtherly, flat ropes or band can be made by the material with high towability, for example have fiber or reinforcing bar urethanes or rubber sheath.
Flat ropes 52 has first and second ends 54,56, and each end all is connected in the top of hoistway 12.Preferably first end 54 of flat ropes 52 is connected on the strut member 36, and second end 56 of flat ropes is connected on the top board 58 of hoistway 12.As shown in Figure 2, flat ropes 52 is extended downwards from first end 54 of strut member 36, around roughly 180 ° on counterweight pulley 50, extend upward again and around roughly 180 ° of drive pulley 44, downward then extension is also passed through first and second elevator pulleys 20,22 from bottom hung lift car 16, roughly extends upward and end at second end 56 at top board 58 places of hoistway 12 again.
Be used for first and second director elements 60,62 that lift car 16 and counterweight 48 are led respectively along the length setting of first and second pillar stiffeners 24,26.Director element 60,62 can be made one with pillar stiffener 24,26 or leave and around being arranged on the periphery of pillar stiffener.As shown in Figure 1, first and second guides 60,62 define the first and second elevator guide surfaces 64,66 respectively.The first and second elevator guide surfaces 64,66 minutes at least on corresponding to the length of the pillar stiffener in elevator cage operation path not along first and second pillar stiffeners, 24,26 vertical extent.The apparent surface 68,70 of lift car 16 is processed to definite shape to mesh in a movable manner with the first and second elevator guide surfaces 64,66 respectively when first and second pillar stiffeners 24,26 move when lift car.First and second guides 60,62 also define the first and second counterweight guide surfaces 72,74 respectively.The first and second counterweight guide surfaces 72,74 at least on corresponding to the length of the pillar stiffener in weight counterbalance operation path not along first and second pillar stiffeners, 24,26 vertical extent.The additional apparent surface 76,78 of counterweight 48 is processed to definite shape to mesh in a movable manner with the first and second counterweight guide surfaces 72,74 respectively when pillar stiffener moves when counterweight.In order more to clearly illustrate the rope layout among Fig. 2, the graphic lift car 16 and first and second pillar stiffeners 24,26 are spaced apart.
During operation, the signal that CD-ROM drive motor 42 is received the controller (not shown) rotates to drive described drive pulley 44 in the counterclockwise direction, so that lift car 16 moves up along hoistway 12.The part of drive pulley 44 pulling flat ropes 52 between drive pulley 44 and elevator pulley 20,22 that rotates counterclockwise moves up, and make elevator pulley 56 roll successively, thereby along hoistway 12 elevator 16 that moves up along flat ropes towards its second end.When drive pulley 44 was rotated in the counterclockwise direction, increasing around drive pulley 44 and towards counterweight pulley 50 downward parts of extending of flat ropes 52 made the counterweight pulley rotate counterclockwise, thereby counterweight 48 descended along hoistway 12.
The signal that CD-ROM drive motor 42 is also received controller rotates to drive described drive pulley 44 in the clockwise direction, so that lift car 16 moves down along hoistway 12.Drive pulley 44 pullings that clockwise rotate make the counterweight pulley clockwise rotate, thereby counterweight 48 are moved up along hoistway 12 around drive pulley 44 and towards counterweight pulley 50 downward flat ropes 52 of extending.The drive pulley 44 that clockwise rotates also makes the part of flat ropes 52 between drive pulley and flat ropes 52 second ends 56 increase, make elevator pulley 20,22 roll and leave its second end, thereby lift car 16 is moved down along hoistway 12 along flat ropes.

CD-ROM drive motor 202 and drive pulley 204 are connected in the top of hoistway 12, for example are connected on the sidewall 206 (as shown in Figure 4) or top board 208 of hoistway.CD-ROM drive motor 202 can be for example gear or belt deceleration type, reducing required motor torque, and aligns in hoistway 12 vertical extent spaces, and this space is between the lift car 16 and hoistway wall 206 in the hoistway.Lift car comprises first and second elevator pulleys 20,22 that are connected to the lift car bottom and are positioned at the relative both sides of car.Counterweight 48 and the counterweight pulley 50 that is connected to its top are arranged on CD-ROM drive motor 202 belows, and preferably with lift car 16 in hoistway 12 and sidewall 206 between the space in CD-ROM drive motor align.Flat ropes or band 210 have first and second ends 212,214 that link to each other with the top of hoistway 12.As shown in Figure 4, first and second ends 212,214 are connected on the top board 208 of hoistway 12 in relative basically both sides.Flat ropes 210 is roughly extended downwards from its first end 212, around roughly 180 ° on counterweight pulley 50, roughly extend upward then, around drive pulley 204 roughly 180 ° roughly extend downwards again and by pulley 20,22 from bottom hung lift car 16, roughly extend upward and end at second end 214 at its top board that is positioned at hoistway 12 208 places then.Adopting certain rope layout aspect moving elevator car 16 and counterweight 48, the mode of operation of elevator device 10 is similar shown in the mode of operation of elevator device 200 and Fig. 1 and 2, has therefore just no longer illustrated.
Referring to Fig. 5 and 6, indicate with sequence number 300 usually according to the described elevator device of another embodiment of the present invention.Represent with identical sequence number with the element that previous embodiment is similar.To describe the embodiment shown in Fig. 5 and 6 at the part different below with previous embodiment.
Elevator device 300 comprises one first strut member 302, it roughly is connected along horizontal-extending between the relative both sides 304,306 of hoistway at the top of hoistway 12 and with described both sides 304,306, and first strut member 302 is also above the vertical extent space of extending along the hoistway between lift car 16 and the hoistway wall 308.Similarly, second strut member 310 roughly is connected along horizontal-extending between the hoistway 12 relative both sides 304,306 of well headroom and with described both sides 304,306, preferably is positioned at identical plane with first strut member 302.Second strut member 310 and places between first strut member 302 and the lift car also above the vertical extent space of extending along the hoistway between lift car 16 and the hoistway wall 308 12.First and second deflection sheavies 312,314 are connected respectively on first and second supporting members 302,310.
Counterweight 316 with the counterweight pulley 318 that is connected to its top is preferably disposed on first and second strut members, 302,310 belows, and in the vertical extent space of extending, so that service worker can enter wherein easily and safely along the hoistway between lift car 16 and the hoistway wall 308 12.By the associated drives pulley 322 of CD-ROM drive motor 320 (for example brushless motor of direct drive) and the hoistway bottom in the vertical extent space of extending along the hoistway between lift car 16 and the sidewall 308, lift car 16 and counterweight 316 move up and down along hoistway 12 respectively.As shown in Figure 6, CD-ROM drive motor 320 and drive pulley 322 are installed on the floor 324 in the hoistway cavity 326.But flat ropes or band 328 are with type of drive and drive pulley 322 engagements, to make lift car 16 and counterweight 316 vertical shifting along hoistway 12.Flat ropes 328 has first and second ends 330,332 that are connected in hoistway 12 tops.As shown in Figure 6, first end 330 of flat ropes 328 is connected with second strut member 310, second end 332 with roughly be in the top board 334 of lift car 16 and link to each other with respect to the hoistway 12 of first end, 330 opposite sides.Flat ropes 328 is roughly extended downwards from first end 330 that it is positioned at second strut member 310, around counterweight pulley 318 about 180 °, extend upward again and around roughly 180 ° of first deflection sheavies 312, roughly extend downwards then and around roughly 180 ° of drive pulley 322, roughly extend upward again and around roughly 180 ° of second deflection sheavies 314, then roughly extend downwards also and hang lift cars 16, roughly extend upward again and second end 332 at top board 334 places of hoistway stops by first and second elevator pulleys 20,22.
During operation, the signal that CD-ROM drive motor 320 is received the controller (not shown) rotates to drive described drive pulley 322 in the clockwise direction, with the part of downward pulling flat ropes 328 between the drive pulley 322 and second strut member 310.Flat ropes 328 these parts that move down are turned around and are made second deflection sheave 314 rotate, and make the contraction in length of the part of flat ropes between second deflection sheave 314 and flat ropes second end 332.The part of flat ropes 328 these shortening length makes elevator pulley 20,22 along its rolling and towards its second end 332, thereby lift car 16 is moved up along hoistway 12.The drive pulley 322 that clockwise rotates also makes the part of flat ropes 328 between the drive pulley 322 and first deflection sheave 302 move up, and the deflection sheave of winning is rotated and counterweight 316 is moved down along hoistway.
During operation, the signal that CD-ROM drive motor 320 is received the controller (not shown) rotates to drive described drive pulley 322 in the counterclockwise direction, upwards to spur the part of flat ropes 328 between the drive pulley 322 and second strut member 310.Flat ropes 328 these parts that move up are turned around and are made second deflection sheave 314 rotate, and the length of the part of flat ropes between second deflection sheave and flat ropes second end 332 is increased.The part of flat ropes 328 these increase length makes elevator pulley 20,22 along its rolling and away from its second end 332, thereby lift car 16 is moved down along hoistway 12.The drive pulley 322 that rotates counterclockwise also makes the part of flat ropes 328 between the drive pulley and first deflection sheave 302 move down, and the deflection sheave of winning is rotated and counterweight 316 is moved up along hoistway.
Principal character of the present invention is to have used flat ropes in above-mentioned elevator device.The increase of size ratio causes rope to have an active flank that is limited by width " W ", and this makes the distribution of rope pressure be optimized.Therefore, the maximum rope pressure in the rope can reach minimum.In addition, green phase increases above-mentioned size than (the size ratio of circular rope equals 1) for circular rope, and the thickness of flat ropes " t1 " (see figure 8) can reduce, and keeps being used in the rope supporting the constant cross-section area at the rope position of tensile 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 the .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 keep maximum rope pressure to be in the acceptable limit simultaneously.
Mating surface 730 contacts with the corresponding surface 750 of hauling block 724.Overplate 728 is by polyamine base ethyl formate material, preferably thermoplastics type's amido ethyl formate is made, 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 amido ethyl formate although can adopt other materials for overplate.According to the mechanical characteristics of thermoplastics type's amido ethyl formate, 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, and 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 complementary type 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.
Though according to embodiments of the invention the present invention is illustrated and describes, but those skilled in the art should be known in change, omission and the increase that can make other under the situation that does not break away from the spirit and scope of the present invention in form and details.For example, can adopt other rope layouts, wherein CD-ROM drive motor is set in place the hoistway side between lift car and hoistway wall.Exception, CD-ROM drive motor also can be arranged on the hoistway superjacent air space between lift car and the sidewall.Therefore, the present invention represented and that describe represents in the mode of example among each embodiment, rather than limitation of the present invention.
