Definitions

  • the present invention relates to an art of layout in an elevator without a machine room.
  • Fig. 11 is a plan view of a hoist-way in a conventional elevator without a machine room as disclosed in JP-A-2000-255933 (Pages 7 and 8, Figs. 15 and 16), showing relation between a sheave of a winding machine and turning pulleys provided at a top of the hoist-way
  • Fig. 12 is a vertical sectional view of the hoist-way.
  • the drawings show an elevator device having 2:1 roping which includes a cage 3 suspended by a hoisting rope 15 which is wound around a sheave 4a of a winding machine 4 at the top of the hoist-way, and a balance weight 9 which moves up and down in proportion to the cage.
  • the winding machine 4, the sheave 4a and a first turning pulley 5 are arranged in parallel to a ceiling face of the hoist-way, and the hoisting rope is turned to a vertical direction by means of a second turningpulley 6 and then, wound around two suspending pulleys 18 which are pivotally attached to a lower part of the cage thereby to suspend the cage 3.
  • the balance weight 9 is suspended by turning the hoisting rope 15 from the sheave 4a to a vertical direction by means of a turning pulley 7 at a side of the balance weight, and by winding the hoisting rope 15 around a suspending pulley 19 which is pivotally attached to the weight balance 9.
  • WO 02-22486 is a prior art document which discloses features falling under the characterising portion of Claims 1 and 3.
  • EP 1 057 771 A2 is further prior art.
  • This invention has been made in order to solve the above described problems, and an object of the invention is to obtain an elevator having 1:1 roping in which a hoist-way is decreased to the smallest in size, while a maintenance space for a winding machine can be secured.
  • an elevator device comprises the features of Claim 1.
  • first turning pulley and the second turning pulley are in combination preferably having different diameters from each other.
  • the winding machine, sheave and turning pulleys are made smaller in size, and a plurality of the turning pulleys which are not in parallel to the ceiling of the hoist-way are arranged in a gap between the cage and the wall of the hoist-way.
  • a rope having excellent flexibility or a steel rope having a small diameter and high strength is applied to the hoisting rope, and the winding machine, sheave and turning pulleys are made smaller in size.
  • Fig. 1 is a plan view showing relation between a sheave of a winding machine and turning pulleys at the top of the hoist-way in Embodiment 1 according to this invention
  • Fig. 2 is a vertical sectional view of the hoist-way.
  • the drawings show an elevator device having 1:1 roping which includes a cage 3 moving up and down along a pair of guide rails 10 provided in the hoist-way, a hoisting rope 13 which is engaged at its one end with the cage 3 and engaged at the other end with a balance weight 9 moving up and down along other guide rails 11, and a winding machine 4 having a sheave 4a around which the hoisting rope is wound.
  • the elevator device is constructed in such a manner that the winding machine 4 is arranged close to a wall of the hoist-way in an upper part of the hoist-way, the sheave 4a is provided so as not to be in parallel to a ceiling face of the hoist-way, a plurality of the ropes 13 are divided into more than two lines of a first turning pulley 5 and a second turning pulley 6 which are arranged in parallel to the ceiling face of the hoist-way to be deflected to a center of gravity of the cage, and the ropes are further turned to a vertical direction by means of a third turning pulley 8 and engaged with rope retaining parts of the cage thereby to suspend the cage.
  • the 1:1 roping can be attained even in a narrow gap at the top of the hoist-way, and even though a number of the hoisting ropes are employed, a rope fleet angle, that is, an angle at which the ropes are likely to be detached from rope grooves in the sheave or the turning pulleys can be depressed to a small angle, because a plurality, more than two, of the first turning pulley and the second turning pulley are employed.
  • the rope fleet angle can be made small, deflected abrasion of the rope grooves can be restrained, and noises can be decreased, thus enabling effective lives of the ropes to be prolonged.
  • Fig. 3 is a plan view corresponding to Fig. 1 , showing Embodiment 2.
  • Fig. 4 is a vertical sectional view of the hoist-way in Fig. 3 .
  • Embodiment 2 is the same as the above described structure, except that two turning pulleys, namely the second turning pulley 6 and a third turning pulley 6a are employed, while the first turning pulley 5 is single, in other words, the three turning pulleys in total from the first to the third are employed.
  • the same members or equivalent members as in the foregoing embodiment are designated by the same reference numerals, further description will be omitted.
  • Fig. 5 is a plan view corresponding to Fig. 3 , showing Embodiment 3, and Fig. 4 is a vertical sectional view of the hoist-way in Fig. 5 .
  • the two turning pulleys namely the second turning pulley 6 and the third turning pulley 6a are combined, while the first turning pulley 5 is single.
  • the diameter of the turning pulley 5 is made smaller so as to match a turning angle of the rope 13 drawn out from the sheave 4a of the winding machine to the center of gravity of the cage in view of a layout, and a diameter of a single second turning pulley 6b is made larger instead of employing the two turning pulleys 6 and 6a.
  • the diameter of the second turning pulley 6b is selected so as to match the turning angles of the sheave 4a and the turning pulley 5, thereby to restrict angles of the ropes with respect to respective rope grooves in the third turning pulley 8 within an allowable range. Further description will be omitted, because arrangement of the other members is the same as in Embodiment 2, and the same reference numerals designate the same members or equivalent members.
  • the optimum rope fleet angle can be obtained by making the diameters of the first turning pulley and the second turning pulley different from each other, and by selecting and combining the diameters of the turning pulleys so as to match differences between the turning angles of the rope.
  • the shaft and bearing beam of the second turning pulley 6b are located apart from the first turning pulley 5, and interference will not occur. Accordingly, such an advantage that the turning pulleys can be positioned more close to each other in a vertical direction, and the above described rope fleet angle can be made smaller can be attained.
  • Fig. 6 is a plan view corresponding to Fig. 1 , showing Embodiment 4, and Fig. 7 is a vertical sectional view of the hoist-way in Fig. 6 .
  • the drawings show an elevator device having the 1:1 roping which includes a cage, a hoisting rope which is engaged at its one end with the cage and engaged at the other end with a balance weight which moves up and down with respect to the cage, and a winding machine having a sheave around which the hoisting rope is wound.
  • the elevator device is constructed in such a manner that the above described winding machine 4 is arranged close to the wall of the hoist-way in the upper part of the hoist-way, the above described sheave 4a is provided so as not to be in parallel to the ceiling face of the hoist-way, a plurality of the ropes 13 from the sheave 4a to the cage are divided to the first turning pulley 5 and the second turning pulley 6 which are arranged in parallel to the ceiling face of the hoist-way to be deflected, and the ropes are further turned to a vertical direction respectively by means of a third turning pulley 8a and a fourth turning pulley 8b for the purpose of dropping down the ropes to two rope retaining parts at both sides of the cage, thereby to suspend the cage.
  • the 1:1 roping can be attained in a narrow gap at the top of the hoist-way, and a deflected load will not be exerted on the cage, because the cage is suspended at two points surrounding the center of gravity of the cage. Therefore, this elevator device can be applied to the elevator having a large capacity.
  • the rope fleet angle can be made small because the ropes are divided to the first turning pulley and the second turning pulley.
  • the rope fleet angle can be made small, deflected abrasion of the rope grooves can be restrained, and noises can be decreased, thus enabling effective lives of the ropes to be prolonged.
  • Fig. 8 is a plan view corresponding to Fig. 6 , showing Embodiment 5, and Fig. 7 is a vertical sectional view of the hoist-way in Fig. 8 .
  • the winding machine, sheave and turning pulleys are made smaller in size, and all of a plurality of the turning pulleys which are not in parallel to the ceiling of the hoist-way are arranged in a gap between the cage and the wall of the hoist-way. Further description will be omitted, because arrangement of the other members is the same as in the foregoing embodiments, and the same reference numerals designate the same members or equivalent members.
  • the turning pulleys are arranged in the gap between the cage and the wall of the hoist-way, they are not overlapped on a plain of the cage and become free from restraint in the gap above the top of the cage. Accordingly, such an advantage that the turning pulleys can be contained in the narrow gap above the top of the cage can be obtained.
  • Fig. 9 is a plan view corresponding to Fig. 8 , showing Embodiment 6, and Fig. 10 is a vertical sectional view of the hoist-way in Fig. 9 .
  • a rope having excellent flexibility or a steel rope having a small diameter and high strength is applied to the hoisting rope, and the winding machine, sheave and turning pulleys are made smaller in size, in the above described elevators. Further description will be omitted, because arrangement of the other members is the same as in the foregoing embodiments. It is self-explanatory that such application of the steel rope having the small diameter and high strength, and downsizing of the winding machine, sheave and turning pulleys can be also applied to Embodiments 1 to 4 in the same manner.
  • the elevator device having 1:1 roping which includes a cage moving up and down along a pair of guide rails provided in a hoist-way, a hoisting rope which is engaged at its one end with the aforesaid cage and engaged at the other end with a balance weight moving up and down along other guide rails, and a winding machine having a sheave around which the aforesaid hoisting rope is wound is constructed in such a manner that the aforesaid winding machine is disposed close to a wall of the hoist-way in an upper part of the hoist-way, having the aforesaid sheave arranged not in parallel to a ceiling face of the hoist-way, a plurality of the ropes stretched from the aforesaid sheave to the aforesaid cage are divided into more than two lines of a first turning pulley and a second turning pulley which are arranged in parallel to the ceiling of the hoist-way thereby to be deflected to a center
  • the 1:1 roping can be attained even in the narrow gap at the top of the hoist-way, and even though a number of the hoisting ropes are employed, the rope fleet angle, that is, the angle at which the ropes are likely to-be detached from the rope grooves in the sheave or the turning pulleys can be depressed to a small angle, because a plurality of the first turning pulleys are employed.
