Definitions

  • the invention relates to elevator system with a compensation of Tragseilmassen from middle to strong off-center ("backpack") Suspended cars and a traction sheave drive, the in a shaft, in a shaft niche or in a separate one Room is housed, with the traction sheave of the Support rope either simple, with or without diverter, or doubly entwined, as well as with a direct or indirect suspension of the car and a counterweight, and, furthermore, a supply carried by the car. and function control hanger harness and a mass balancing device.
  • the principle is the following: In an upper car position is the carrying rope mass, calculated from the traction sheave, until to the car due to the short support rope length small, for but the mass of the equalizer due to its length from the car to its lower reversal point. At a lower car position, the situation is reversed. The same applies to the counterweight. In this way receives one on the half payload a significantly reduced maximum drive and braking power.
  • the usual suspension cable mass balance is in a known manner by a compensating element in the form of chains, weight-loaded Belts or realized by taut sub ropes (US 4,716,989).
  • the compensation element is on the one hand on the car and on the other hand attached to the counterweight.
  • In the Shaft pit is the compensation element with or without jigs diverted.
  • Tensioned Compensation Elements with or Without vibration-damped tensioning device are preferably for driving speeds of the elevator v> 2.5 m / s used.
  • EP 1 234 796 A1 is a compensation device of Tragseilmassen through the interposition of balancing elements on the one hand between the car and the shaft wall and on the other between counterweight and shaft wall, combined each with a data transmission element.
  • a disadvantage of the latter compensation devices is likewise the high space requirement of the counterweight compensation in the elevator shaft through the diversion in the pit and the attachment and arrangement of the same in the shaft behind the Counterweight or in an oblique arrangement before, without the Car to collide. That means bigger in any case Well dimensions as usual.
  • Another disadvantage is that the additional masses at least consist of 2 strands, namely the strand for the car and the strand for the counterweight, not counting the data transmission lines.
  • the invention is based on the object, the indicated Disadvantages to avoid and an elevator system of the beginning described genus with a space-saving, constructive extremely simple, visually acceptable and easy to use To provide balancing mass arrangement.
  • An elevator system according to the invention can be particularly advantageous at the limit of driveability problems, more limited Number of rope grooves of the elevator machine, larger heads, greater speeds and used where Lower ropes, chains or other compensation devices more usual 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 Visual restrictions due to usual compensating devices, Noises and other things.
  • the invention is based on an embodiment closer to be discribed.
  • a traction sheave 1 in the upper Area of a shaft 2 arranged.
  • a Set of carrying ropes 3 in simple wrap around the traction sheave 1 led.
  • a counterweight 4 directly attached and on the other side a car 5.
  • the suspension cable guide and suspension is for the invention insignificant.
  • a double Looping be provided or an additional deflection disc and car 5 and counterweight 4 can be in bulk Be hung role.
  • the mass of the equalizer is 7 per meter together with the mass of the hanging cable harness 6 per meter therefore 4 times the mass of the supporting rope 3 per meter, with a mass greater than 4 times the balancing effect deteriorates again.
  • the compensation line 7 from one or more single strands.
  • the Compensating strand 7 For elevators with speeds of up to 8 m / s, the Compensating strand 7 to be designed to be untensioned, beyond he should in a further embodiment of the invention in one Guided guided and optionally by means of a roll tensioning system to be excited.
