Definitions

  • the invention relates to a lift for heavy loads consisting of an elevator car and a counterweight, the traversable along guide rails Elevator car along with guide rails movable counterweight by means of a via a Traction sheave guided rope is connected and the rope of a first cable hinge point on a first guide roller of the Counterweight; continue on a first pulley, continue on a second pulley of the counterweight, continue on the driven by a drive unit traction sheave, continue from the traction sheave to one below the Elevator car arranged first pulley pair, continue on a second pulley, continue on one below the Elevator car arranged second deflection roller pair and continues to run on a second rope fix point.
  • WO 03/010081 From the document WO 03/010081 is an elevator device become known, in which the drive unit a guide rail of the elevator car, on a Guide rail of the counterweight and on a support column supported. In addition, a traverse is provided, which is at one end to the second guide rail of the counterweight and at the other end to the console of the drive unit supported. The one rope fix point is at the crossbar arranged.
  • a disadvantage of this device is the expensive solution to Support of the drive unit on a support column.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the task to avoid the disadvantages of the known device and to provide a lift with a 4: 1 cable guide, the is just under construction.
  • Fig. 1 shows a known from the prior art Elevator with an elevator car 1 and a counterweight 2, wherein the elevator car 1 with the counterweight 2 means connected via a traction sheave 3 rope 4 connected is.
  • the traction sheave 3 is by means of a drive unit 5 driven. It is a 4: 1 rope guide with Sublimation of the elevator car 1 provided with, with one meter rope movement on the traction sheave 3 the Elevator car 1 and the counterweight 2 vertically around moved a quarter of a meter.
  • the rope 4 is from an upper first rope fixation point 6 a first deflection roller 7 of the counterweight 2, on an upper first guide roller 8, further to a second Guide roller 9 of the counterweight 2, continue on the above arranged, by means of the drive unit 5 drivable Traction sheave 3, further from the traction sheave 3 on a arranged below the elevator car 1 first Deflection pulley pair 10, further on an upper second Deflection pulley 11, further to a below the elevator car 1 arranged second pulley pair 12 and on an upper second cable fix point 13 out.
  • Fig. 2 shows a plan view of the inventive Elevator with a 4: 1 cable guide.
  • the one in one Elevator shaft 14 along a first Cabin guide rail 15 and a second Cabin guide rail 16 movable elevator car 1 has at least one car door 17, which by means of a not shown door drive with a landing door 18th cooperates.
  • the counterweight 2 is along a first counterweight guide rail 19 and along a second counterweight guide rail 20 in the elevator shaft 14th movable, which is limited by shaft walls 14.1 and a shaft ceiling 14.2.
  • the top part of the Elevator shaft 14 is designated shaft head 14.3.
  • the rope 4 is a rope strand with several parallel trained ropes. For simplicity's sake continue to maintain the term "rope”.
  • the Drive unit 5 can, for example, an asynchronous motor or have a synchronous motor with permanent magnets.
  • the arrangement of the pulleys 7,8,9,10,11,12, the Traction sheave 3 and the drive unit 5 is from the Floor plan of Fig. 2 can be seen, wherein the longitudinal axis of Drive unit 5 with traction sheave 3 perpendicular to Schachtwand runs, at least the Guides 19,20 of the counterweight 2 arranged are.
  • Fig. 3 and Fig. 4 show details of the arrangement of Drive unit 5 and the upper first guide roller 8 of the inventive elevator.
  • a carrier 21 is supported at one end on the first cab guide 15 and the first counterweight guide rail 19 and the other end the second counterweight guide rail 20.
  • the Guide rails are by means of brackets 22 with the shaft wall 14.1 connected, the vertical rail forces in the Manhole are routed.
  • One arranged on the carrier 21 Drive console 23 carries the drive unit 5 and the Traction sheave 3.
  • a roller console arranged on the carrier 21 24 carries the upper first pulley 8.
  • the upper first rope fixation point 6 and the upper second Seilfixtician 13 arranged on the carrier 21.
  • FIG. 5 and Fig. 6 show details of the arrangement of upper second deflection roller 11 of the inventive Elevator.
  • a roller console 25 is based on the second car guide rail 16 and carries the upper second pulley 11.
  • the pulley bracket 25 has a Boom 26 on which a speed limiter 27th attachable.
  • the guide rail 11 is by means of ironing 22 connected to the shaft wall 14.1, wherein the vertical Rail forces are directed into the pit.
  • Fig. 7 shows a variant of the arrangement of Drive unit 5 with traction sheave 3.
  • the longitudinal axis of Drive unit 5 with traction sheave 3 runs parallel to Shaft wall, at least the guide rails 19,20 of the counterweight 2 are arranged.
  • the pulleys 7.9 the counterweight 2 and the guide roller 8 of the carrier 21st are arranged diagonally.
  • the rope fixing points 6,13 are continue to be provided on the carrier 21.
