Definitions

  • the present invention relates to a roller guide for a car of an elevator system for guiding along a guide rail and such a car and such an elevator system.
  • Carriages are guided in elevator shafts by means of guides, in particular roller guides, along guide rails.
  • guides in particular roller guides, along guide rails.
  • the diameters of the rollers used in the roller guides can be increased, which leads to lower accelerations of the wheel axle when driving over irregularities on the rolling surface of the guide rails and thus to greater comfort.
  • the ride comfort can be increased by soft running surfaces of the rollers, since in this case the irregularities of the rolling surface are better absorbed.
  • a roller guide according to the invention is used for a car of an elevator system for guiding along a guide rail.
  • the roller guide has a roller carrier which is attachable to the car, wherein on the roller carrier a plurality of rollers are arranged such that the rollers are rolled with their respective running surface on the same rolling surface of the guide rail, and wherein the rollers in the roller carrier with each a direction component are mounted movably perpendicular to the rolling surface of the guide rail.
  • roller guide By such a roller guide, the force that is transmitted via the roller guide to the guide rail, distributed over several roles. As a result, the individual roles can be made smaller than would be the case with a single role.
  • a roller guide according to the invention at the same time a higher ride comfort, as possible unevenness on the rolling surface of the guide rail, which usually have small dimensions, usually act on only one of the plurality of roles. Since the rollers are individually movably mounted in the direction vertical to the rolling surface, the unevenness acts on only one roller at a time, while the remaining rollers continue to provide the regular guidance and therefore compensate, at least in part, for the unevenness.
  • each support be substantially perpendicular to the rolling surface, particularly preferably completely perpendicular to the rolling surface, since thus due to Avoidance of unnecessary bearing loads and friction due to skewed movements and thus a particularly effective power transmission is achieved in terms of life and comfort improvement.
  • rollers can be selected as needed, but at least two rollers for the effect of the invention are necessary. Particularly preferred are three or four rollers, but also five, six or more roles are conceivable. For the sake of completeness, it should also be mentioned that rollers can rest on the guide rail on two or three rolling surfaces for guidance. In such cases, the roller guide for the other rolling surfaces may also be carried out according to the invention.
  • the rollers are arranged on the roller carrier in the direction of movement of the car with respect to their axes spaced from each other.
  • the rollers can be arranged, for example, in a row with a certain distance between two rollers.
  • the force acting on the roller guide by the car force can be optimally distributed to the guide rail, while ensuring that the most local unevenness on the usually narrow guide rails each act on only one of the rollers.
  • the rollers are arranged on the roller carrier in the direction of movement of the car overlapping.
  • the rollers can be arranged, for example, overlapping in two rows.
  • the roller guide at least in the direction of movement of the car, be made compact.
  • the rollers are supported in operative connection with each other such that a movement of one of the rollers in a direction perpendicular to the rolling surface of the guide rail causes an opposite movement of at least one of the remaining rollers. That is, at least one roller moves in a direction opposite to the former.
  • the movement of a first roller which is caused by an unevenness in the rolling surface of the guide rail, is compensated by a movement of at least one further roller, preferably even as far as possible by a movement of all other rollers.
  • the force on the first roll is thus reduced directly by the at least one other role.
  • a possible swinging of the first roll is avoided.
  • the operative connection between the rollers is at least partially formed by means of a hydraulic fluid.
  • a hydraulic operative connection is largely independent of the exact geometric configuration of the roller guide and can therefore be adapted particularly easily to a roller guide or its roller carrier.
  • an attenuation of the movements can be predetermined, which is optimally adapted to the other elasticities, for example, of the rollers and the load-bearing components, which are unavoidable in the system, in the sense that this follows a local unevenness Harmonics are minimized in terms of time and size.
  • the rollers are each movably mounted by means of hydraulically interconnected hydraulic cylinders and corresponding pistons.
  • hydraulic cylinder is explicitly not intended to be limited to a cylindrical shape, although such is customary for such applications. This allows a particularly simple realization of the movably mounted rollers, since hydraulic cylinders can be simply connected to one another by hydraulic hoses, for example. However, for example, corresponding channels can also be provided in the roller carrier.
  • the hydraulic fluid is enclosed by an at least partially flexible container, the rollers being respectively coupled to an outside of the container such that movement of the rollers in a direction perpendicular to the rolling surface of the guide rail is transferred to the hydraulic fluid via the outside of the container.
  • a container eg. Of rubber, flexible plastic or similar material.
  • a non-linearity of the force transmission between the roller and the hydraulic fluid can be perpendicular to the movement of the roller be reached to the rolling surface. For example. higher stiffness can be achieved for higher deflections of the rollers.
  • the container is arranged on and / or in the roller carrier. This is a particularly compact design possible.
  • An inventive car of an elevator system has at least one roller guide according to the invention.
  • An elevator system according to the invention has at least one car according to the invention and at least one guide rail.
  • FIG. 1 shows schematically a roller guide according to the invention in a preferred embodiment.
  • Figure 2 shows schematically a roller guide according to the invention in a further preferred embodiment.
  • Figure 3 shows schematically a roller guide according to the invention in a further preferred embodiment.
  • FIG. 1 schematically shows a roller guide 100 according to the invention in a preferred embodiment.
  • the roller guide 100 has a roller carrier 110 and exemplarily four rollers 120. Furthermore, a guide rail 180 is shown, along which the roller carrier 100 can be moved.
  • the roller guide 100 can be attached to a car of an elevator system via the roller carrier 110, for example, a simple screw connection can be provided for this purpose.
  • a car usually has a plurality of roller guides.
  • the usual direction of movement of the car and thus also of the roller guide 100 takes place vertically in an elevator shaft along the associated guide rail 180, while in the figure the direction of movement is shown horizontally for the sake of clarity.
  • the guide rail 180 has a rolling surface 181, on which the rollers 120 abut with their respective running surface in regular operation and roll. Furthermore, a bump 182 is shown in the rolling surface 181, which may be, for example, an impurity, a damage or a weld.
  • the rollers 120 each have a piston 130 on which the rollers 120 are rotatably mounted at one end about their respective axes.
  • the pistons 130 are disposed in associated hydraulic cylinders 125 and movably supported in the direction perpendicular to the rolling surface 181.
  • the corresponding storage and possibly additionally necessary holding devices which secure the rollers against falling out are not shown for the sake of clarity.
  • the hydraulic cylinders 125 are arranged in the roller carrier 110 or form part of the roller carrier 110.
  • the four hydraulic cylinders 125 shown are connected to one another via a channel 135. In this channel 135, which may be, for example, a bore in the roller carrier 110, there is a hydraulic fluid 140th
  • All pistons 130 are acted on at one end with the hydraulic fluid 140.
  • the acted upon by the hydraulic fluid 140 surfaces of the piston 130 are present all the same size, so that a force transmission between a piston and the hydraulic fluid 140 at a movement of the associated role perpendicular to the rolling surface 181 for all rollers 120 is equal. If one of the rollers 120 now overruns an unevenness 182 during rolling on the guide rail 180, ie when moving the associated car, as shown by way of example for the right-hand roller in FIG. 1, this roller is lifted or into the roller carrier 110 pushed. Accordingly, the other three rollers are lowered or pushed out of the roller carrier 110.
  • the height by which the right roller is pressed into the roller support 110 is distributed evenly among the other three rollers by the hydraulic fluid 140, i. each of these other three rollers is pushed out of the roller carrier only a third of that height or distance. This results in an elevation of the right roll relative to the rolling surface about the height which it is forced into the roll carrier and in addition to a third of that height, i. the height by which each of the other three rollers is pushed out of the roller carrier 110.
  • the roller carrier 110 is raised only by a quarter of the height of the irregularity 182 relative to the rolling surface 181.
  • roller carrier 110 is illustrated by a concrete example.
  • the right-hand roller is pressed in by 3 mm into the roller carrier 110.
  • These 3 mm are evenly distributed on the other three rollers, which are therefore pressed out by 1 mm from the roller carrier.
  • the height difference between the right roll and the other three rolls is thus 4 mm, while the roll carrier 110 is raised in total by only 1 mm with respect to the rolling surface 181.
  • FIG. 2 schematically shows a roller guide 100 according to the invention in a further preferred embodiment.
  • the roller guide 100 differs from the roller guide according to FIG. 1 in that firstly only three rollers 120 are provided and secondly that the rollers 120 overlap in the direction of movement of the roller guide 100 or of the car.
  • the smaller distance between two rollers overcomes the irregularity of two successive rollers at a shorter distance. This means that, depending on the length of the irregularity in the direction of movement of the car, the second role may possibly already raised, while the first role is still in decline. This leads to a smoother motion sequence and thus also increases ride comfort.
  • FIG. 3 schematically shows a roller guide 100 according to the invention in a further preferred embodiment.
  • the rollers 120 are not supported by interconnected hydraulic cylinders and corresponding pistons.
  • the rollers 120 each have a holder 160, on which the rollers 120 are rotatably mounted at one end about their respective axes.
  • the brackets 160 are disposed in associated openings in the roller carrier 110 and movably supported in a direction perpendicular to the rolling surface 181.
  • the appropriate storage and possibly additionally necessary holding devices which To prevent them from falling out, they are not shown further for the sake of clarity.
  • the roller carrier 110 has in the present case in the interior a cavity in which a container 150 is arranged.
  • the container is made, for example, from a flexible plastic, rubber or similar material and encloses the hydraulic fluid 140.
  • the holders 160 of the rollers 120 are coupled to an outside of the container 150 such that both movement of a holder into the roller carrier 110 are transferred to the hydraulic fluid 140 as well as a pressure change in the hydraulic fluid 140 to the brackets.
  • Movement of a roller into the roller carrier 110 therefore results in movement of the other three rollers out of the roller carrier 110.
  • the movement of the right-hand roller is distributed at least approximately uniformly over the other rollers so that these other three rollers are only about one-third of the height that the one roller is pressed into the roller carrier 110 to be pushed out.
  • attention must be paid to a suitable shaping of the container 150 and the locations of the coupling to the brackets 160.
  • the advantage here is that the power transmission can also be designed non-linear. This then happens at the expense of a uniform force transmission, but in favor of other desired properties of the roller guide, such as, for example, a higher rigidity with larger deflections.
