Definitions

  • the present invention relates to an arrangement as defined in the preamble of claim 1 in the guiding of the counterweight of an elevator.
  • FIG. 5 shows a top view of an elevator car and counterweight so placed in the elevator shaft that the guide rails are as close to each other as possible. It can be seen from the figure that both the elevator car and the counterweight are provided with sliding guides, because there is not enough space between the guide rails for roller guides, which have two wheels on the sides of the guide rail and one wheel against the dorsal edge of the guide rail .
  • the object of the present invention is to overcome the above-mentioned drawbacks and to enable the use of roller guides on the counterweight in traction sheave elevators provided with thin hoisting ropes in cases where shaft space is used sparingly.
  • a further object of the invention is to allow the use of sturdy and rigid guide rail joints and fastenings and also to enable a suspension as centric as possible e.g. in respect of gripping forces.
  • the invention By applying the invention, one or more of the following, among others, can be achieved: due to thin hoisting ropes and a high suspension ratio, the traction sheave and rope pulleys are small and light as compared with those used in conventional elevators due to the small traction sheave, the operating brakes of the elevator are smaller due to the small traction sheave, the torque requirement is lower, allowing the use of both a smaller motor and smaller operating brakes as a result of a smaller traction sheave and a large suspension ratio, a higher rotational speed is needed in order to achieve a given speed of the elevator car, so the same motor output power can be achieved by a smaller motor a small traction sheave allows the use of a smaller driving motor of the elevator, which means a reduction of the acquisition/manufacturing costs of the driving motor the small size of the machine and thin ropes allow relatively easy placement of the elevator machine the weight of the elevator car and counterweight can be completely or at least partially carried by the elevator guide rails in elevators applying the invention,
  • the primary sphere of application of the invention is elevators designed for the transportation of people and/or freight .
  • the elevator solution of the invention uses sub- stantially thin ropes having a diameter of e.g. about 4...6 mm.
  • Fig. 1 presents a diagrammatic and simplified top view of a counterweight arrangement in an elevator shaft according to the invention
  • Fig. 2 presents a diagrammatic top view of the solution of Fig. 1, additionally showing the placement of the diverting pulleys.
  • FIGs 1 and 2 are diagrams representing a typical elevator suspension solution according to the invention, wherein the hoisting machine 5 of an elevator moving in an elevator shaft 1 is connected via a traction sheave 6 to a set of hoisting ropes consisting of mutually parallel hoisting ropes 2 of e.g. substantially round cross-section and supporting a counterweight 4 moving along its tracks, i.e. guide rails 9 and 11, and an elevator car 3 moving on guide rails 7.
  • the track of the counterweight 4 is so disposed between the elevator car 3 and the wall of the elevator shaft that the longer sides 17 and 18 of the cross-section of the counterweight 4 are substantially parallel to the nearest wall of the elevator car 3 and to the adjacent wall of the elevator shaft 1.
  • the counterweight 4 itself has not been rotated to an oblique position relative to the elevator car guide rail line, but the longer sides 17 and 18 of the counterweight are substantially perpendicular to the guide rail line of the guide rails 7 of the elevator car 3.
  • the parallel hoisting ropes 2 are represented in the figures only by their cross-sectional surface in the vertical portion of the ropes.
  • the elevator car 3 is provided with roller guides 8, which move along the three guide surfaces of a substantially vertical guide rail 7 as the elevator car is traveling upwards and downwards in the elevator shaft.
  • the counterweight 4 is also provided with roller guides 10, which move along the three guide surfaces of a substantially vertical guide rail 9, 11 as the counterweight is moving in the elevator shaft.
  • the counterweight 4 is a modified rectangle such that two diagonally opposite corners of the counterweight have been beveled by cutting off a substantially triangular piece.
  • the corners thus beveled have a planar surface 15 at a suitable angle to the center line of the counterweight 4.
  • the beveled corners are so located at the corners of the counterweight that the corner the one of the corners which is closer to the guide rail 7 of the elevator car is farther away from the elevator car 3 than the beveled corner of the counterweight placed farther away from the guide rail 7.
  • Mounted on each planar surface 15 at the corner of the counterweight is a counterweight roller guide 10 in such manner that the middle one of the three rollers points substantially towards the mass center 16 of the counterweight.
  • the guide rails 9 and 11 of the counterweight 4 are placed in a rotated position relative to the center line of the counterweight near the beveled corners of the counterweight .
  • the angle of rotation corresponds to the bevel angle of the planar surface, and thus both the guide rails 9, 11 and the roller guides 10 and the mass center 16 of the counterweight are all sub- stantially on the same line.
  • the guide rail 11 is fixed to the elevator shaft by means of brackets 12.
  • the guide rail line of the guide rails 9, 11 of the counterweight 4 has been rotated to an oblique position relative to the guide rail line of the guide rails 7 of the elevator car in such manner that the angle of rotation is substantially in the range of 0...90 0 . Due to this rotation, the counterweight guide rail 9 placed closer to the car guide rail 7 is farther removed from the elevator car than in prior-art solutions. Therefore, the counterweight guide rail 9 is also farther removed from guide rail 7 of the elevator car, thus allowing the use of roller guides.
  • the other counterweight guide rail 11, mounted at a larger distance from the car guide rail 7, is placed closer to the elevator car than guide rail 9.
  • the angle of rotation can be adjusted according to the dimensions of the counterweight so that the hoisting point and the mass center 16 of the counterweight coincide and the guide rail line crosses the same point. This solution is advantageous in respect of sliding friction and gripping forces .
  • Fig. 2 additionally presents by way of example a diagrammatic representation of one type of placement of diverting pulleys 13, 14 in the rope suspension as seen from above.
  • One of the decisive factors in the placement of the diverting pulleys is the space required for the passage of the ropes .
  • a counterweight differing from the above description in its cross-section and having roller guides (10) placed substantially in the same way as described above.
  • the corners of the counterweight need not necessarily be beveled over the entire height of the counterweight but only in the region of the fastening point of the roller guides. Even this beveling is not necessarily needed if the mounting of the roller guides (10) is implemented in a manner such that the roller guides are at an oblique position as described above but the cross-section of the counterweight is substantially rectangular over its entire height.
  • the mounting of the roller guides is implemented e.g. by fastening the roller guide to two adjacent side surfaces of the counterweight around the corner between the sides .
  • the corners of the counterweight may also be beveled symmetrically so that all the corners are beveled in the same way.
  • the elevator of the invention is characterized by what is disclosed in the characterization part of claim 1.
  • Other embodiments of the invention are characterized by what is disclosed in the other claims.
  • Inventive embodiments are also presented in the description section of this application.
  • the inventive content disclosed in the application can also be defined in other ways than is done in the claims below.
  • the inventive content may also consist of several separate inventions, especially if the invention is considered in the light of expressions or implicit sub- tasks or in respect of advantages or sets of advantages achieved. In this case, some of the attributes contained in the claims below may be superfluous from the point of view of separate inventive concepts.
