Definitions

  • the present invention relates to a device for vibration damping on elevator cabs, which are held in a support frame, wherein in order to attenuate the horizontal and vertical impacts transmitted from the support frame to the car, support buffers between the support frame and the underside of the car, an upper element for horizontally centering the relative position of the upper part the cabin in the support frame, which simultaneously brakes the horizontal deflection, and a lower element for horizontal centering of the relative position of the lower part of the cabin in the support frame, which simultaneously brakes the horizontal deflection, are provided.
  • US Pat. No. 4,428,460 describes a combined device by means of which the lower part of a car body is supported on four individual plates suspended in articulated quadrilaterals and additional rubber buffers and the upper part of the car body is guided by centering elements. The transverse deflection is counteracted with adjustable spring elements.
  • the device comprises numerous, complicated mechanical elements, which can cause corresponding problems and costs in terms of function and maintenance.
  • a system is known from US Pat. No. 4,660,682, in which the lower part of the cabin is horizontally movably supported in all directions on roller or slide guides and the upper part is held in a central position between the supporting frame and the cabin by means of damping elements.
  • the horizontal deflection of the lower part of the cabin takes place against spring forces that center the cabin.
  • a mechanical stop centering is provided, which consists of the actuating cylinder and levers.
  • the intervention of the mechanical centering device can transmit noise and impacts to the cabin.
  • the deflection of the lower part of the cabin corresponds to a pendulum movement, which means that every point on the underside of the cabin moves on a circular line around the center of rotation of the top of the cabin. This in turn has the consequence that in particular the outer points on the underside of the cabin have to make a corresponding vertical movement.
  • the integration of a load measurement is also difficult.
  • U.S. Patent No. 4,113,064 describes a similar device. This is mechanically blocked with an electromagnet, which is attached to the support frame and, when excited, attracts a rubber-mounted plate located on the cabin body. The friction generated by the friction brakes further horizontal deflection of the cabin. The necessary vertical flexibility is only partially given. The mechanical blocking device will be noticeable by an impact sound and it is not intended to operate it while driving.
  • the present invention has for its object to provide a device that strongly dampen the horizontal and vertical impacts on a cabin held in a support frame during fast travel and can bridge the damping function if necessary.
  • side plates 4, a lower yoke 3 and an upper yoke 2 form a support frame for a cabin body 1.
  • the support frame is guided with guide shoes 5 in guide rails 5.1 and carried with ropes 6.
  • 5.2 is a guide rail joint.
  • the cabin body 1 lies on ball roller buffers 8, which are fastened in the horizontal leg 15.2 of the support bracket 15 with bolts 8.3 and nuts 8.4.
  • 15.1 are elements of a static load measurement and are attached below and above at the beginning of the leg of the horizontal leg 15.2 of the support bracket 15. 7 with a lower centering element is referred to, which consists of a jacket 7.1, a rubber-elastic filling 7.2 and a guide sleeve 7.3.
  • a ball joint with a release and tensioning device 14 In the ball joint there is a spherical body 12 with a guide bolt 11 which passes through its center, is firmly connected to it and projects upwards. The part of the guide bolt 11 which projects upwards is located after an open space 11.1 in the guide slide sleeve 7.3.
  • a dashed contour 8.2 shows the shape of the ball in the unloaded state as a ball and the drawn-out contour 8.1 shows it in the normally loaded state.
  • the top of the car body 1 has guide bolts 9 which are fastened to the car body 1 with plates 9.1.
  • These guide bolts 9 pass through guide sliding sleeves 10.3 of centering elements 10, which in turn are attached to the upper yoke 2 with the jacket 10.1.
  • the centering elements 10 have a rubber-elastic filling 10.2 between the jacket 10.1 and the guide sliding sleeve 10.3.
  • Fig. 2 illustrates an example of the placement of the centering element 7, the ball roller buffer 8 and the guide pin 9 on the cabin body 1.
  • the ball roller buffer 8 are located below the four corners of the cabin body 1.
  • the lower centering element 7 is attached centrally and the guide pins 9 are in line a guide axis 5.3 arranged on the top of the cabin.
  • FIG. 3 shows a top view of the ball joint 13 with a clamping and releasing device 14.
  • a fixed clamping jaw 13.2 is located on a base plate 13.1, which is firmly connected to the base plate 13.1 and movably connected to the fixed clamping jaw 13.2 via a hinge 13.4 , a movable jaw 13.3.
  • a short leg 13.5 with a transverse bore 13.6 is fastened to the end of the fixed clamping jaw 13.2 opposite the hinge 13.4 and a long leg 13.7 with an outer transverse bore 13.8 and an inner transverse bore 13.9 at the same point on the movable clamping jaw 13.3.
  • the tensioning and releasing device 14 consists of two separate Functional groups, one for tensioning and one for loosening.
  • the one for loosening acts on the outer end of the long leg 13.7 by a draw bolt 14.6 leading through the outer bore 13.8 and being attracted by an electromagnet 14.5 when it is excited.
  • the electromagnet 14.5 is fixed with an angle support 14.10 on the same base as the base plate 13.1.
  • the opening travel is limited with an adjusting screw 14.7 with nut 14.8.
  • the set screw is held by a flange plate 14.9, which is firmly connected to the electromagnet 14.5.
  • the point of engagement of the set screw 14.7 lies in the middle between the outer bore 13.8 and the inner bore 13.9 on the long leg 13.7. Is tensioned with a clamping bolt 14.1, which is guided through the holes 13.6 and 13.9, and with a tension spring 14.3, which is preloaded with nuts 14.2 via washer 14.4.
  • 12 denotes a spherical body which is flattened at the top and bottom and has a bevel 12.3 at the lower edge.
  • An upwardly projecting bolt 11 is firmly connected to the spherical body 12.
  • these two parts 11 and 12 can move about a center 12.4 within an available angle of rotation.
  • X 7.4 at half the height in the centering element 7 denotes another pivot point.
  • An additional buffer pad 12.2 reduces the movement angle for the spherical body 12 at this point.
  • the device described above works as follows:
  • the underside of the cabin body rests on ball rolling buffers 8.
  • Vibration buffers with a spherical shape have the property that their force-displacement characteristic curve is very progressive.
  • Working point is the vertical spring travel of the cabin body with a maximum load change, for example at most 2 mm.
  • Higher frequency mechanical vibrations eg> 10 Hz
  • the car body 1 can now roll on these ball rolling buffers 8 sufficiently far in all horizontal directions without the movement being hindered by the screw bolts 8.3 and thus intercept lateral impacts from a known cause, with a lateral evasive movement relative to the supporting frame 4, and from the passengers keep away.
  • the car body 1 with its lower part performs these shock-absorbing evasive movements while driving, the car top is held in a defined central position by the two guide bolts 9 and centering elements 10 arranged in line.
  • the guide bolts 9 can slide in the guide slide sleeves 10.3 in the vertical direction, so that when the cabin body 1 moves vertically, there is no additional vertical force due to a change in load or deflection of the lower part.
  • the centering elements 10 with the rubber-elastic filling 10.2 can absorb higher-frequency transverse vibrations and keep them away from the cabin body 1.
  • the deflection movement of the lower part of the cabin body 1 must be limited because the spatial conditions in the shaft, in particular the distance to the front wall of the shaft, are limited.
  • the buffer pad 12.1 in the ball joint 13 is determined.
  • the deflection movement of the lower part of the cabin body 1 pulls the bolt 11 at an angle and thus also the spherical body 12 until it lies with its bevel 12.3 on the buffer support 12.1 and then, depending on the specific surface pressure and the Shore hardness of the buffer support 12.1, makes a corresponding buffer path.
  • Practical application shows that the deflection in the guide axis can and should be greater than that in the direction of the shaft wall with the entrances.
  • the deflection towards the exits must never reach the amount of the threshold air gap and secondly, the function of the mechanical coupling of the shaft and cabin doors must not be impaired.
  • the door coupling mechanisms are attached to the upper half of a car body, so that because of the centering elements 10 and the guide bolts 9 on the upper part of the car body 1, they only have to participate in a fraction of the deflection movement.
  • the door threshold gap is currently on the level of the greatest deflection movement, which must be checked or limited absolutely safely and reliably in the direction towards the entrance. This is done by targeted additional buffer supports 12.2 in the ball joint 13 at the point which reduces the deflection path of the cabin body 1 to the admissible dimensions towards the entrances.
  • the permissible dimension of the deflection path in this direction can be, for example, 10 mm, 15 to 20 mm then being permissible for the other directions of movement.
  • Natural vibrations of the car body 1 in the natural resonance range of, for example, 1 to 1.5 Hz are caused by the internal damping friction of the rubber-elastic Fillings 7.2 / 10.2 and that of the ball roller buffer 8 prevented.
  • the disposition and dimensions of the individual components of the device according to the invention are matched to the cabin mass, the maximum speed to be driven and the local conditions.
  • the elements of a static load measurement 15.1 work completely independently of the functions of the device according to the invention, because with vertical movements of the cabin body 1, the sliding guide sleeves 7.3 / 10.3, the guide bolts 9 and the bolts 11 do not produce vertical forces which distort the load measurement.
  • the translation geometry between the horizontal Cabin movement and that of the bevel 12.3 on the underside of the spherical body 12 is given by the distance X between the two pivot points 12.4 and 7.4 and the diameter of the spherical body 12. Changes in the distance X due to changes in load are taken into account millimeter by millimeter.
