Definitions

  • the present invention relates generally to an elevator system, and more particularly to an elevator system including a drive motor provided between an elevator car and a hoistway sidewall, the motor driving a rope or ropes by traction.
  • BS 5655 Part I 1986 defines a traction drive lift as a lift whose ropes are driven by function in the grooves of the driving sheave of the machine.
  • EP-A-0 719 724 discloses a traction sheave elevator wherein a flat drive motor unit is placed in a machine space provided in the elevator shaft or in a wall structure of the shaft.
  • EP-A-0 710 618 discloses a traction sheave elevator wherein the drive machine unit is placed in a top part of the elevator shaft..
  • the present invention provides a traction drive elevator system as claimed in claims 1, 2 and 16.
  • An advantage of the present invention is that the elevator system significantly reduces the space and construction costs associated with an elevator system having a machine room.
  • a second advantage of the present invention is the provision of several alternative drive motor locations.
  • a third advantage of the present invention is that flat rope technology reduces the size of the drive motor and sheaves, and thereby reduces the space between the elevator car and sidewall of the hoistway required for accommodating the motor and sheaves.
  • an elevator system embodying the present invention is generally designated by the reference number 10.
  • the elevator system includes a hoistway 12 defined by a surrounding structure 14.
  • An elevator car 16 is disposed in the hoistway 12 for upward and downward movement therealong.
  • First and second elevator sheaves 20, 22 are coupled to an underside of the elevator car 16 at opposite sides relative to each other.
  • the elevator system 10 includes first and second support columns 24, 26 disposed at one side 28 of the elevator car 16, and generally at opposite sides 30, 32 of the hoistway 12 relative to each other.
  • Each of the first and second support columns 24, 26 extends vertically from a bottom portion or floor 34 of the hoistway 12 to an upper portion of the hoistway.
  • a support member 36 (shown by the dashed lines in FIG.1) is mounted on and extends generally horizontally between the first and second support columns 24, 26 at a top portion of the hoistway 12.
  • a drive motor 42 including a drive sheave 44 drivingly coupled to the drive motor, is supported on the support member 36 and is aligned within a vertically extending space along the hoistway 12 between the elevator car 16 and a sidewall 46 of the hoistway.
  • the elevator system 10 further includes a counterweight 48 having a counterweight sheave 50 coupled to a top portion of the counterweight.
  • the counterweight 48 is situated below and preferably aligned with the drive motor 42 in the vertically-extending space along the hoistway 12 between the elevator car 16 and the sidewall 46.
  • the counterweight 48 is coupled to the elevator car 16 via a flat rope or belt for balancing the elevator car during its vertical movement along the hoistway 12.
  • flat ropes or belts permit smaller drive motors and sheaves to drive and suspend elevator car and counterweight loads relative to drive motors and sheaves using conventional round ropes.
  • the diameter of drive sheaves used in elevators with conventional round ropes is limited to 40 times the diameter of the ropes, or larger, due to fatigue of the ropes as they repeatedly conform to the diameter of the sheave and straighten out.
  • Torque is proportional to the diameter of the traction sheave. Therefore, the use of a smaller diameter traction sheave reduces motor torque.
  • Motor size (rotor volume) is roughly proportional to torque; therefore, although the mechanical output power remains the same regardless of sheave size, flat ropes or belts allow the use of a smaller drive motor operating at a higher speed relative to systems using conventional round ropes. Consequently, smaller conventional and flat drive motors may be accommodated in the hoistway between the elevator car and a sidewall of the hoistway which significantly reduces the size and construction cost of the hoistway.
  • reducing the machine size i.e., drive motor and sheaves
  • the smaller machine reduces the hoistway space requirement when the machine is located above the elevator car and sidewall of the hoistway.
  • a small machine utilizes less material, and will be less costly to produce relative to a larger machine.
  • the light weight of a small machine reduces the time for handling the machine and the need for equipment to lift the machine into place so as to significantly reduce installation cost.
  • low torque and high speed allow the elimination of gears, which are costly. Further, gears can cause vibrations and noise, and require maintenance of lubrication.
  • geared machines may be employed if desired.
  • Flat ropes or belts also distribute the elevator and counterweight loads over a greater surface area on the sheaves relative to round ropes for reduced specific pressure on the ropes, thus increasing its operating life.
  • the flat ropes or belts may be made from a high traction material such as urethane or rubber jacket with fiber or steel reinforcement.
  • the flat rope 52 has first and second ends 54, 56 each coupled within a top portion of the hoistway 12.
  • the first end 54 of the flat rope 52 is coupled to the support member 36 and the second end 56 of the flat rope is coupled to a ceiling 58 of the hoistway 12.
  • the flat rope 52 extends downwardly from its first end 54 at the support member 36, loops generally 180° about the counterweight sheave 50, extends upwardly and loops generally 180° about the drive sheave 44, extends generally downwardly and underslings the elevator car 16 via the first and second elevator sheaves 20, 22, and extends generally upwardly and terminates at its second end 56 at the ceiling 58 of the hoistway 12.
  • First and second guide members 60, 62 for guiding the elevator car 16 and the counterweight 48 are respectively disposed along the length of the first and second support columns 24, 26.
  • the guide members 60, 62 may be formed integrally with the support columns 24, 26 or may be separate from and disposed about a perimeter of the support columns.
  • the first and second guide members 60, 62 respectively define first and second elevator guide surfaces 64, 66.
  • the first and second elevator guide surfaces 64, 66 respectively extend vertically along the first and second support columns 24, 26 at least over a length of the support columns corresponding to the path of elevator car travel.
  • Opposing surfaces 68, 70 of the elevator car 16 are shaped to be movably engagable with respective first and second elevator guide surfaces 64, 66 as the elevator car moves vertically along the first and second support columns 24, 26.
  • the first and second guide members 60, 62 also respectively define first and second counterweight guide surfaces 72, 74.
  • the first and second counterweight guide surfaces 72, 74 respectively extend vertically along the first and second support columns 24, 26 at least over a length of the support columns corresponding to the path of counterweight travel.
  • Additional opposing surfaces 76, 78 of the counterweight 48 are shaped to be movably engagable with respective first and second counterweight guide surfaces 72, 74 as the counterweight moves vertically along the support columns.
  • the elevator car 16 is shown as being spaced from the first and second support columns 24, 26.
  • the drive motor 42 is signaled by a controller (not shown) to rotate the drive sheave 44 in a counterclockwise direction to move the elevator car 16 upwardly along the hoistway 12.
  • the counterclockwise rotating drive sheave 44 pulls a portion of the flat rope 52 between the drive sheave 44 and the elevator sheaves 20, 22 upwardly, and in turn, causes the elevator sheaves to roll along the flat rope toward its second end 56 to thereby move the elevator 16 upwardly along the hoistway 12.
  • the drive motor 42 is also signaled by a controller to rotate the drive sheave 44 in a clockwise direction to move the elevator car 16 downwardly along the hoistway 12.
  • the clockwise rotating drive sheave 44 pulls a portion of the flat rope 52 looping about the drive sheave 44 and extending downwardly toward the counterweight sheave 50 which causes the counterweight sheave to rotate in a clockwise direction, to thereby move the counterweight 48 upwardly along the hoistway 12.
  • the clockwise rotating drive sheave 44 also lengthens a portion of the flat rope 52 between the drive sheave and the second end 56 of the flat rope 52 which causes the elevator sheaves 20, 22 to roll along the flat rope away from its second end to thereby move the elevator car 16 downwardly along the hoistway 12.
  • the provision of the drive motor within the space along the hoistway between the elevator car and a sidewall of the hoistway minimizes internal building height requirements because no machinery occupies the overhead projection of the elevator car or within the hoistway pit.
  • the provision of the machinery to the side of the elevator car also reduces the overhead dimension of the hoistway in that space is only required for rope elongation, buffer stroke and jump allowance for the counterweight.
  • FIG. 3 an elevator system in accordance with a second embodiment of the present invention is generally designated by the reference number 100.
  • the elevator system 100 is similar to the elevator system 10 except that the elevator system 100 employs a 1:1 roping configuration which does not employ a counterweight sheave or elevator sheaves.
  • the embodiment of FIG. 3 will be explained with respect to its aspects which are different from previous embodiments.
  • a first end 102 of the flat rope 52 is coupled to a top portion of the counterweight 48, and a second end 104 of the flat rope is coupled to a lower portion of the elevator car 16.
  • the flat rope 52 extends generally upwardly from its first end 102 at a top portion of the counterweight 48, loops generally 180° about the drive sheave 44, and extends generally downwardly and is coupled to a lower portion of the elevator car 16 at 106.

  • the drive motor 42 is signaled by a controller (not shown) to rotate the drive sheave 44 in a counterclockwise direction to move the elevator car 16 upwardly along the hoistway 12.

  • a portion of the flat rope 52 extending between the drive sheave 44 and the counterweight 48 increases in length, whereby the counterweight is lowered along the hoistway 12.
  • the drive motor is also signaled by a controller to rotate the drive sheave 44 in a clockwise direction to move the elevator car 16 downwardly along the hoistway 12 via the guide members 60, 62.

  • the second support member 310 is aligned over the vertically extending space along the hoistway 12 between the elevator car 16 and the sidewall 308, and is interposed between the first support member 302 and the elevator car.
  • First and second deflector sheaves 312, 314 are respectively coupled to the first and second support members 302, 310.

  • the elevator car 16 and the counterweight 316 are moved upwardly and downwardly along the hoistway 12, in part, by means of a drive motor 320, such as a direct drive brushless motor, and associated drive sheave 322 situated at a lower portion of the hoistway within the vertically extending space along the hoistway between the elevator car 16 and the sidewall 308. As shown in FIG.
  • the drive motor 320 and the drive sheave 322 are mounted to a floor 324 within a hoistway pit 326.
  • a flat rope or belt 328 is drivingly engaged with the drive sheave 322 to move the elevator car 16 and the counterweight 316 vertically along the hoistway 12.
  • the flat rope 328 has first and second ends 330, 332 coupled within a top portion of the hoistway 12. As shown in FIG. 6, the first end 330 of the flat rope 328 is coupled to the second support member 310 and the second end 332 is coupled to a ceiling 334 of the hoistway 12 generally at an opposite side of the elevator car 16 relative to the first end 330.

  • the drive motor 320 is signaled by a controller (not shown) to rotate the drive sheave 322 in a clockwise direction which pulls downwardly on a portion of the flat rope 328 between the drive sheave 322 and the second support member 310.
  • This downwardly moving portion of the flat rope 328 in turn causes the second deflector sheave 314 to rotate so as to shorten the length of a portion of the flat rope between the second deflector sheave 314 and the second end 332 of the flat rope.
  • the elevator sheaves 20, 22 are caused by this shortening portion of the flat rope 328 to roll therealong toward its second end 332, thereby moving the elevator car 16 upwardly along the hoistway 12.
  • the clockwise rotating drive sheave 322 also moves upwardly a portion of the flat rope 328 between the drive sheave 322 and the first deflector sheave 302 causing the first deflector sheave to rotate so as to move the counterweight 316 downwardly along the hoistway 12.
  • the drive motor 320 is also signaled by a controller to rotate the drive sheave 322 in a counterclockwise direction which moves upwardly a portion of the flat rope 328 between the drive sheave and the second support member 310.
  • This upwardly moving portion of the flat rope 328 in turn causes the second deflector sheave 310 to rotate so as to increase the length of a portion of the flat rope between the second deflector sheave and the second end 332 of the flat rope.
  • the elevator sheaves 20, 22 are caused by this lengthening portion of the flat rope 328 to roll therealong away from its second end 332, thereby moving the elevator car 16 downwardly along the hoistway 12.
  • the counterclockwise rotating drive sheave 322 also moves downwardly a portion of the flat rope 328 between the drive sheave and the first deflector sheave 302 causing the first deflector sheave to rotate so as to move the counterweight 316 upwardly along the hoistway 12.
  • An essential feature of the present invention is the flatness of the ropes used in the above described elevator system.
  • the increase in aspect ratio results in a rope that has an engagement surface, defined by the width dimension "w", that is optimized to distribute the rope pressure. Therefore, the maximum rope pressure is minimized within the rope.
  • the thickness "t1" of the flat rope may be reduced while maintaining a constant cross-sectional area of the portions of the rope supporting the tension load in the rope.
  • the flat ropes 722 include a plurality of individual load carrying cords 726 encased within a common layer of coating 728.
  • the coating layer 728 separates the individual cords 726 and defines an engagement surface 730 for engaging the traction sheave 724.
  • the load carrying cords 726 may be formed from a high-strength, lightweight non-metallic material, such as aramid fibers, or may be formed from a metallic material, such as thin, high-carbon steel fibers. It is desirable to maintain the thickness "d" of the cords 726 as small as possible in order to maximize the flexibility and minimize the stress in the cords 726.
  • the fiber diameters should be less than .25 millimeters in diameter and preferably in the range of about 10 millimeters to .20 millimeters in diameter.
  • Steel fibers having such diameter improve the flexibility of the cords and the rope.
  • the traction sheave diameter "D" may be reduced while maintaining the maximum rope pressure within acceptable limits.
  • the engagement surface 730 is in contact with a corresponding surface 750 of the traction sheave 724.
  • the coating layer 728 is formed from a polyurethane material, preferably a thermoplastic urethane, that is extruded onto and through the plurality of cords 726 in such a manner that each of the individual cords 726 is restrained against longitudinal movement relative to the other cords 726.
  • Other materials may also be used for the coating layer if they are sufficient to meet the required functions of the coating layer: traction, wear, transmission of traction loads to the cords and resistance to environmental factors.
  • thermoplastic urethane if they do not meet or exceed the mechanical properties of a thermoplastic urethane, then the benefits resulting from the use of flat ropes may be reduced. With the thermoplastic urethane mechanical properties the traction sheave 724 diameter is reducible to 100 millimeters or less.
  • the rope pressure may be distributed more uniformly throughout the rope 722. Because of the incorporation of a plurality of small cords 726 into the flat rope elastomer coating layer 728, the pressure on each cord 726 is significantly diminished over prior art ropes. Cord pressure is decreased at least as n -1 ⁇ 2 , with n being the number of parallel cords in the flat rope, for a given load and wire cross section. Therefore, the maximum rope pressure in the flat rope is significantly reduced as compared to a conventionally roped elevator having a similar load carrying capacity.
  • the effective rope diameter 'd' (measured in the bending direction) is reduced for the equivalent load bearing capacity and smaller values for the sheave diameter 'D' may be attained without a reduction in the D/d ratio.
  • minimizing the diameter D of the sheave permits the use of less costly, more compact, high speed motors as the drive machine.
  • a traction sheave 724 having a traction surface 750 configured to receive the flat rope 722 is also shown in FIG. 7.
  • the engagement surface 750 is complementarily shaped to provide traction and to guide the engagement between the flat ropes 722 and the sheave 724.
  • the traction sheave 724 includes a pair of rims 744 disposed on opposite sides of the sheave 724 and one or more dividers 745 disposed between adjacent flat ropes.
  • the traction sheave 724 also includes liners 742 received within the spaces between the rims 744 and dividers 745.
  • the liners 742 define the engagement surface 750 such that there are lateral gaps 754 between the sides of the flat ropes 722 and the liners 742.
  • a traction sheave without liners may be used.
