Definitions

  • the invention relates to an elevator installation.
  • the invention is applicable to elevator systems with at least one car, in particular a plurality of cars, which can be moved in a lift shaft via guide rails.
  • At least one fixed first guide rail is fixedly arranged in an elevator shaft and is aligned in a first, in particular vertical, direction;
  • at least one fixed second guide rail is aligned in a second, in particular horizontal, direction;
  • at least one third guide rail rotatable relative to the elevator shaft is fastened to a rotary platform and can be transferred between an orientation in the first direction and an alignment in the second direction.

  • Another form of conversion unit may be provided.
  • the car has a brake, which should reduce the driving speed. In a horizontal travel, however, other braking forces are required than in a vertical drive. So far, this circumstance is realized by different control of the brakes and / or the use of separate brakes.
  • the first rail has a first rail width and the second rail has a second rail width; the second rail width is less than the first rail width.
  • the brake is in particular a safety brake whose braking force can not be selectively metered during operation. If an emergency stop is initiated, such a safety brake is activated, which then uses the full spring force to close the brake.
  • Such a brake is activated in particular by releasing a brake spring, which is kept pretensioned during normal operation.
  • the brake spring provides the braking force in the activated case and causes a safety braking, regardless of whether the car is in a vertical or horizontal travel.
  • significantly higher braking forces are required for a vertical travel than for a horizontal travel.
  • a significantly low braking force is desirable to minimize the consequences of acceleration in the horizontal direction (comparable to an emergency braking in a subway).
  • first rail and the second rail are aligned in different directions.
  • first rail has a steeper orientation than the second rail.
  • “steeper” means: the rail is oriented at a greater angle relative to the horizontal plane.
  • the first rail is in particular vertically aligned and / or the second rail is in particular aligned horizontally.
  • the first rail is fixedly aligned in a first, in particular vertical, direction
  • the second rail is firmly aligned in a second, in particular horizontal, direction.

  • the 10 2016 205 794.4 describes in this context in detail an arrangement with integrated platform pivot and a drive unit for rotating the rotary platform, which can also be used in the context of the present invention for storage and as a rotary drive for the rotary platform.

  • FIG. 3 shows the second rail 57, which is horizontally aligned in the elevator installation 50.
  • the second rail 57 has a second rail width B2. Due to the smaller rail width, the brake spring 35 relaxes when applied to the second rail 57 more than when it rests against the first rail 58. Due to the spring characteristic, this reduces the normal force F.
  • 4 shows an example of a simplified spring characteristic of the brake spring 35. In this case, the spring characteristic is linear (over operating range constant spring constant D), which is not mandatory. Taking into account the desired braking force, a rail with the suitable rail width can be selected on the basis of the spring characteristic.

Abstract

L'invention concerne un système d'ascenseur (50), comprenant une cabine (51), au moins un premier rail (56) et un deuxième rail (57), le long duquel la cabine (51) peut être déplacée ; un frein (30) servant à ralentir la cabine par rapport aux rails (56, 57), lequel est mis au point pour appliquer pendant une opération de freinage une force normale (F) sur un des rails (56-8). Le frein (30) est mis au point pour entrer en contact pendant l'opération de freinage avec un des rails (56, 57) sur une première face de freinage (31) et sur une deuxième face de freinage (32). La première face de freinage (31) est opposée à la deuxième face de freinage (32). La distance entre les deux faces de freinage (31) l'une par rapport à l'autre définit une largeur (B1, B2) de rail. Le premier rail (56) présente une première largeur (B1) de rail, et le deuxième rail (57) présente une deuxième largeur (B2) de rail, la deuxième largeur (B2) de rail étant inférieure à la première largeur (B1) de rail.
