Definitions

  • the invention relates to elevator system with a compensation of Lifting rope masses from central to very off-center (“backpack") suspended cars and a traction sheave drive, the in a shaft, in a shaft table or in a separate one Space is housed, the traction sheave of which Suspension rope strand either simple, with or without a deflector, or is wrapped twice, as well as with a direct one or indirect suspension of the car and a counterweight, as well as a supply car carried by the car and function control suspension harness and a mass balancer.
  • backpack very off-center
  • Elevator systems are often used for all conceivable Car full to empty, combined with the car position from top to bottom and one towed by the car Supply and function control pendant wiring harness, Compensating elements for the strand masses for the purpose of reduction until minimization of the rope force differences between the suspension rope on the car side and the suspension cable the counterweight side used.
  • the principle is as follows: With an upper car position is the suspension cable mass, calculated from the traction sheave, up to to the car small due to the short suspension rope length, therefore but the mass of the balancing strand due to its length large from the car to its lower turning point. At a The situation is reversed in the lower car position. The same applies to the counterweight. That way one significantly reduced based on half the payload maximum drive and braking power.
  • the usual suspension cable balancing is done in a known manner through a compensating element in the form of chains, weight-loaded Belts or realized by tensioned lower ropes (U.S. 4,716,989).
  • the compensating element is on the one hand on the car and on the other hand attached to the counterweight.
  • the shaft pit becomes the compensating element with or without clamping devices diverted.
  • Tensioned compensation elements with or without a vibration-damped tensioning device are preferred for travel speeds of the elevator v> 2.5 m / s used.
  • a compensation device is the Support rope masses through the interposition of compensating elements on the one hand between the car and the shaft wall and on the other hand between counterweight and shaft wall, combined in each case with a data transmission element.
  • a disadvantage of the latter compensation devices is likewise the high space requirement of the counterweight balance in the elevator shaft through the redirection in the shaft pit and the attachment and arrangement of the same in the shaft behind the Counterweight or in an inclined arrangement in front of it, without using the Car collide. In any case, that means bigger ones Shaft dimensions than usual.
  • Another disadvantage is that the additional masses at least consist of 2 strands, namely the strand for the car and the line for the counterweight, not counting the data transmission lines.
  • the invention is based on the object shown To avoid disadvantages and an elevator system at the beginning described genus with a space-saving, constructive extremely simple, optically acceptable and easy to use To create balancing mass arrangement.
  • the mass of the hanging cable becomes conscious together with the mass of the compensating element on the 1.75 times the cable mass per meter for partial load compensation and 4 times per meter for ideal compensation enlarged and with the counterweight mass as with the description of a conventional elevator system is taken into account.
  • the compensation element together with the hanging cable acts this car position at all, but hangs fully the shaft wall.
  • the car is in the top one Stop, the mass is fully attached to the car and is the same thus the suspension rope masses, which are now on the counterweight side are located. Together with the increased counterweight mass here again the ideal smallest result Rope force difference values for full or empty Car.
  • An elevator installation according to the invention can be particularly advantageous in the limit range for driving problems, more limited Number of rope grooves in the elevator machine, larger heads, higher speeds and can be used where Lower ropes, chains or other compensating devices are more common Arrangement between car and counterweight undesirable are.
  • Reasons for this can be: lack of space, low Shaft pit, glass shaft in the lower shaft area without View restrictions due to usual compensation devices, Noises and other.
  • the safety gear on the car and, if necessary, the counterweight are sure to adapt to this fact, need less than the acceleration of gravity g decelerate and thus a long-term jumping of the car or counterweight safely prevent.
  • Fig. 1 In the associated single Fig. 1 is strongly traction drive 1 in the upper Area of a shaft 2 arranged.
  • a Set of suspension cables 3 In the example there is a Set of suspension cables 3 in a single loop around the traction sheave 1 led.
  • a counterweight 4 At one end of the suspension rope 3 is a counterweight 4 attached directly and on the other side a car 5.
  • the suspension cable guide and suspension is for the invention is immaterial.
  • a double Wrapping may be provided or an additional deflection disc and car 5 and counterweight 4 can be in bulk Roll be hung.
  • Other variants are conceivable.
  • the mass of the compensating strand is 7 per meter together with the mass of the suspension cable harness 6 per meter therefore 4 times the mass of the suspension cable strand 3 per meter, with a mass greater than 4 times the compensating effect deteriorates again.
  • the compensating strand 7 from one or more single strands.
  • a correspondingly suitable groove shape of the Traction sheave 1 selected, e.g. B. a reduced undercut width or generally, a groove shape with reduced Driving ability, and thus a disproportionately reduced Surface pressure between groove and rope.
  • the Compensation line 7 can be carried out untensioned, in addition should he in a further embodiment of the invention in a Guided and if necessary by means of a roller tensioner to be excited.
