Definitions

  • the present invention relates to an elevator installation, in which at least one elevator car is not suspended centrally above its center of gravity but rather eccentrically or eccentrically or eccentrically on a suspension element.
  • An elevator installation generally comprises an elevator cage and at least one counterweight, which are moved in opposite directions in an elevator shaft.
  • the elevator car and the at least one counterweight run here in or along guide rails.
  • the designed as a T-profile guide rails basically take in this type of eccentric suspension the inclusion of a tilting moment, which is located on an upper guide shoe of the elevator car or at the relevant point of the guide rail in a tensile force and at a lower guide shoe of the elevator car or on the concerned position of the guide rail in a pressure force manifests.
  • a load torque which is generated for example by promoted persons.
  • eccentrically suspended elevator cabs require, on the one hand, correspondingly sturdy guide rails and, on the other hand, guides which withstand the occurring forces.
  • this fact represents a constructive additional expense or disadvantage, so that solutions are sought for this purpose.
  • the patent CH 517,043 discloses a solution for an elevator car, in which a hydraulic thrust piston drive is arranged laterally in the elevator shaft outside the movement space of the elevator car.
  • a wrapping body that is to say rope, which is guided by rollers arranged in mirror-inverted manner, a cradle with a joint is realized, which thus permits a starting of the driving force varying from the direction.
  • This patent thus discloses an improved transmission of a force application point located outside the movement space of the elevator car to another force application point, which lies within the movement space of the elevator car below the center of gravity of the elevator car.
  • the object of the present invention is to find a compensation device for the compensation of the occurring tilting and load moments in an eccentrically suspended elevator car.
  • the solution of the problem consists in the design, arrangement and design of a compensation device, which provides a wrap around rollers on the elevator car with at least one second support means.
  • the wrapping of at least two arranged on the elevator car rollers according to the invention is carried out in opposite directions, in such a way that the wrap by at least one second support means generates a torsion, which acts against the tilting or load moment of the elevator car.
  • a torsion arises from the fact that the at least one second suspension element - hereinafter referred to as compensation means - is guided around a first roller offset from a center axis or centroid line of the elevator car to the guide rails on the elevator car at the top and around a second, from the Center axis or centroid of the elevator car offset in the opposite direction role in opposite directions, ie guided around the bottom. This results in force components that counteract the pressure occurring at the bottom of the elevator car and against the train that occurs at the top of the elevator car.
  • a compensation of this compressive and tensile force can be achieved not only by means of opposing rollers and a suspension means, but also by pulling or pressing mechanical devices that run along, for example on other guide rails with the elevator car. Accordingly, the term compensating means should also include such solutions in the following.
  • an elevator installation with an eccentrically suspended elevator cage for example in the form of a so-called backpack suspension, has the following basic structure:
  • the elevator cage usually runs along two guide rails, which are arranged on one of the four sides of the elevator shaft. On the same side are usually also the drive and the Counterweight arranged.
  • the driving, first carrying and blowing agent is in this case preferably attached as close as possible to the guide rails directly to the elevator car.
  • the second suspension element which may have a round, wedge-shaped or flat cross-section, is made of the materials or material compositions usually used in this field.
  • belts with steel tensile carriers or a gall chain are considered because they have a low elongation and permanent elongation.
  • the support or better said compensating means is fixed at one end, for example, as deep as possible in the elevator shaft and horizontally as far as possible from the guide rails first, lower attachment point attached. From this first, lower attachment point away, the compensation means wraps around a first roller, which is arranged on the lower edge of the elevator car, preferably horizontally as close as possible to the guide rails.
  • the compensating means wraps around a second roll in opposite directions.
  • This second roller is preferably arranged at the upper edge of the elevator car and preferably horizontally as far as possible away from the guide rails. From this second roller, the compensating means leads to a second, upper attachment point, which is preferably as high as possible in the elevator shaft and preferably horizontally as close as possible to the guide rails.
  • This basic variant of a compensating means arrangement optimally ensures possible lever ratios and the smallest possible bending radii of the compensating means, but arrangements are also possible in which the two rollers are arranged at the same height, for example at the lower edge of the elevator car.
  • the support means guide not - as previously described - be diagonally extending, but also vertically extending configured in the elevator shaft.
  • a further refinement variant which is based on what has been described so far, guides the compensating means over rollers which protrude beyond a side wall of the elevator car, ie the rollers are not placed on the underside or on the wall of the elevator car which is opposite the guide rails but on one or more sides. as a symmetrical pair - preferably on both side walls of the elevator car.
  • a further preferred embodiment variant provides on both sides of the elevator car a guidance of the compensating means running diagonally in the elevator shaft. This would require that the door of the elevator car is preferably placed on the front side (the guide rails opposite side) of the elevator car.
  • the compensating means described so far is fixedly attached at both ends. Calculations for this embodiment variant have shown that the compensating means acts in this case with a slightly variable torque against the overturning moment of the elevator car.
  • the compensating means acts in this case with a slightly variable torque against the overturning moment of the elevator car.
  • a constant, unchangeable length variable which is formed by the distance from the first roller to the elevator car to the second roller to the elevator car.
  • the length of the free piece of compensating means increases from the lower attachment point to the first roller. This increase in length occurs at the expense of a decrease in the free length of the compensating means from the second roller to the upper attachment point.
  • the torque which according to the invention is opposed to the overturning moment of the elevator car, has a certain value when the elevator car is in the center of the elevator shaft. This value is formed by a tensile component (pulling away from the guide rails) caused by the lower free piece of balancing means and by a pressure component (pushing towards the guide rails) caused by the upper free piece of balancing means. Towards the lowest and the highest position of the elevator car in the elevator shaft, the two components of the torque shift accordingly.
  • the difference is small.
  • the difference in length only 0.156 m, with a total length of the compensating means of 14 m and a possible accessibility of a minimum length of the upper free piece or the lower free piece of 2.28 m.
  • the length of 2.28 m corresponds to the length of the hypotenuse in a right-angled triangle formed by a horizontal catheter in the form of the cabin depth (1.2 m) and a vertical catheter in the form of a minimally free shaft head height.
  • the calculation is based on the assumption that the upper edge of the elevator car or the lower edge of the elevator car can approach a maximum of 2 m to the shaft ceiling or the shaft floor, from which Consequently, a minimum length of the free pieces of the compensating means of 2.28 m results.
  • a design variant to achieve this provides a compensating means having a defined range of elasticity which is wider than the difference in length.
  • a further embodiment variant, with which the length difference can be compensated provides for a weight-loaded compensating element.
  • a weight-loaded compensating element For this purpose, one of the two fixedly secured ends of the compensating means is no longer fixed, but acted upon in a deflection roller with a defined weight.
  • a spring-loaded rocker can fulfill the same task.
  • the weight is selected in terms of its mass so that, according to the most common cabin or building use, a certain value of the tilting or load moment of the elevator car so compensates that the tensile or compressive forces occurring on the guide rails or at the guide shoes of the elevator car this value is zero.
  • This value may be in the long-term average at half the payload or lower. If the elevator car is empty, or is loaded to the maximum, then only half the tilting or load torque acts on the guides.
  • the weight is adjustable on an approximately horizontally arranged lever and equipped with an electric-electronic control or safety switch for detecting a seating of the lever, which is connected to the entire safety circuit of the elevator system.
  • a further embodiment variant, with which the length difference can be compensated, provides a spring reinforcement of one or both rollers on the elevator car.
  • the rollers can thereby provide in the horizontal direction for a defined compensation in the tension of the compensating means.
  • a related embodiment variant provides for the compensation of the difference in length by a controlled adjustment of the rollers on the elevator car in the horizontal direction.
  • a controlled adjustment for example, piston or a spindle can be provided, which are controlled by means of the information as to how high the elevator car is in the elevator shaft. Accordingly, the rollers are moved horizontally as needed.
  • the Z-shaped arrangement of the compensating means can be spread more or less adaptively in the horizontal direction, but also the ratio of the tensile force of the upper free piece of the compensating means to the tensile force of the lower free piece of the compensating means can be influenced.
  • Another adjustment of the compensating torque is due to sensors which are arranged in the guide shoes of the elevator car. These sensors measure the occurring tensile or compressive force and can on the one hand so provide for a balance that results from the moment difference due to different high positions of the elevator car in the elevator shaft.
  • the guide shoes may additionally be equipped with dampers which dampen any torque peaks that occur when driving off or stopping.
  • roller guides Preferably, the roller guides have a low coefficient of friction and almost identical coefficients of friction with respect to static and dynamic friction.
  • a further embodiment variant of an elevator system according to the invention provides that the elevator car is suspended eccentrically in two respects.
  • the elevator car is suspended from a corner, for example for construction reasons of the building.
  • the tilting or load moment of the elevator car occurs diagonally.
  • this embodiment variant according to the invention provides, in addition to the one or two parallel compensation means, a further, at right angles led compensation means ,
  • the compensation directions thus acting in combination can thus compensate for a diagonally occurring tilting or load torque according to the invention.
  • the compensating means is not fixed stationary on the elevator shaft walls, but attached to the guide rails of the elevator car.
  • the previously shown and inventive Z-shaped arrangement of the compensating means can be realized in this case by the elevator car not only on the side in or along guide rails runs on which the counterweight, the drive and the eccentric suspension are, but also on the opposite side.
  • the elevator car thus runs, for example, on all four edges on guide rails; However, due to the eccentric suspension of the elevator car and the tilting moment caused thereby still occur tensile and compressive forces in the guides, which it according to the invention to eliminate or at least weaken.
  • this can be achieved by the compensating means being mounted in a running manner in separate guide shoes, which are arranged at a distance above and below the elevator car.
  • the absorption of the tensile and compressive forces caused by the tilting moment is advantageously distributed over a greater length of the guide rails.
  • a second embodiment variant in this respect provides, in addition to the two (or four) guide rails for the elevator car, further fastening rails provided only for the compensating means. At least two such opposing mounting rails thus assume the tilting moment-eliminating arrangement of the otherwise also Z-shaped compensating means.
  • the recording of the overturning moment is no longer distributed over a greater length of the elevator car guide rails, but ensured by specially provided mounting rails.
  • the guide shoes of the compensating means no longer have to be at a distance from the guide shoes of the elevator car but can be placed at the same height.
  • the described embodiments according to the invention have in common that the elevator car is hung eccentrically and as a result a tilting moment or undesired forces in the guides occur. Furthermore, they have in common that counteracting these forces by means of a compensating means.
  • a compensating means This is realized, for example, in a Z-shaped guidance of the compensating means via at least two rollers on the elevator car, by arranging a first roller offset from the center of gravity of the elevator car to the elevator car suspension and a second roller from the center of gravity of the elevator car away from the elevator car.

  • a compensating means 11 is guided so that it underlies the second roller 10b away from an attachment point 12a and over-slips the first roller 10a.
  • From the first roller 10a away the compensating means 11 is guided to a second attachment point 12b, which is located in a lever 15.
  • the lever 15 is rotatably articulated in a pivot point 21 and carries a weight 14 which can be moved on the lever 15.
  • Under the lever 15 is a safety switch 20, which triggers when sitting of the lever 15 due to elimination of the tension in the compensating means 11 through the then downwardly rotating lever 15.
