Definitions

  • the invention relates to a braking device for a Elevator with an elevator car and a counterweight, the along guide rails in an elevator shaft can be moved, wherein the braking device on the Elevator car or the counterweight is arranged and at Overspeed the elevator car or the counterweight by means of spring elements and brake wedges to the Guide rails shut down.
  • a disadvantage of the known device is that the spring package and the guides are cast in one piece are.
  • the spring assembly must be applied depending on Braking force are produced, which is the braking device expensive.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the task to avoid the disadvantages of the known device and a braking device with universal structure for Shutting down an elevator car or a counterweight to accomplish.
  • the advantages achieved by the invention are in essential in that a simple Construction of the braking device is possible.
  • the Braking device consists of a few, different Components. Another advantage is that the Braking device with the same components different braking forces can be adjusted. The Brake device is thus without much effort for Elevator cabs or counterweights with different brazeable masses usable.
  • the inventive braking device the possibility of Fine adjustment with respect to the braking force.
  • the spring elements consist of easy-to-manufacture lamellae. Depending on Braking force can be used more or less fins become.
  • Fig. 1 shows a not shown in one Elevator shaft movable elevator car 1, wherein the Elevator car 1 by means of the shaft height extending guide rails 2 is guided.
  • the one with Door 1.1 provided elevator car 1 is from a support frame 3 with a lower yoke 4 and an upper yoke 5 carried.
  • a Braking device 6 arranged in emergency the Elevator car 1 shut down.
  • the elevator car 1 drives by means of an endless rope 7 a not shown rotating speed limiter, which is at a certain overspeed of the elevator car 1 in Down direction blocked.
  • the blocked Speed limiter also blocks that over one not shown arranged in the pit Tension pulley guided endless rope 7, the elevator car 1 however, it continues to move down, with the blocked, connected to a tripping lever 8 endless rope 7 the Braking device 6 engages.
  • the with the endless rope 7 in Connecting tripping lever 8 consists of a Axis of rotation 8.1, at one of the braking device. 6 engaging actuating fork 8.2 is arranged.
  • the Operating fork 8.2 of the opposite Braking device 6 is by means of a at the axis of rotation 8.1 arranged connecting rod 8.3 actuated.
  • at Blocked endless rope 7, also called limiter rope is the axis of rotation 8.1 seen from the cabin door 1.1 ago in Turned clockwise.
  • the operating fork is 8.2 raised at the free end.
  • the elevator car 1 for emergencies in Upstream be shut down.
  • the braking device can also be arranged on the counterweight.
  • Fig. 2 shows details of a guide leg 2.1 of the guide rail 2 acting brake device.
  • 6 To visualize the details of the braking device. 6 is the guide rail 2 in the region of the braking device. 6 shown interrupted.
  • the braking device 6 is made from a yoke arranged at the 4.5 housing 9, as Carrier is used for spring packs 10 and / or for Justiervole 11.
  • the housing 9 also serves as a carrier and guide for Wedge guide elements 12, which in turn brake wedges 13 with Hold and guide brake pads 14.
  • a push rod 15 engages on the one hand on the brake wedge 13, on the other hand is the Push rod 15 hinged to the actuating fork 8.2.
  • the modular spring assemblies 10 and the modular built Justierwee 11 are each end by means of a Spring clip 16 with the wedge guide element 12 releasably connected, wherein lugs 10.1 and 11.1 of the spring packs 10th or the Justierwee 11 slipping of the packages 10,11 prevent the wedge guide elements 12.
  • the packets 10, 11 each end are for example one Threaded pin 17 and nuts 17.1 connected, with first Support 12.2 of the wedge guide elements 12 and at least one second support 9.2 of the housing 9 from the spring packs 10th and Justiervolen 11 hold existing overall package.
  • a spring package 10 consists of ten Slats 10.2 of the same thickness and the same material.
  • the geometrically slightly smaller Justierverse 11 consist in shown example of three slats 11.2.
  • the slats 10.2, 11.2 are punched, for example, from sheet metal.
  • Other Slat materials or different slat thicknesses are also possible.
  • the slats 10.2,11.2 can also differing from the C-shape shown a different shape exhibit.
  • the individual spring assemblies or Justiervole the Braking device 6 can also have a different number Have lamellas. Depending on the number of slats, material, Slat thickness or lamella shape can different spring constants are generated, which are directly affect the braking force.
  • the wedge guide element 12 is in first grooves 9.1 of Housing 9 out and has an extension 12.1. In normal operation, the brake wedge 13 by means of Extension 12.1 and the push rod 15 in rest position held.
  • the spring packs be arranged on a support body 20, wherein the For example, C-shaped support body 20 on the Keil Replacements institute 12 acts.
  • the spring packs 21st consist of at least one lamella 21.1 and are in Grooves 22 of the support body 20 inserted.
  • Im shown Example are three grooves or three spring assemblies 21st intended. It can also have more or less than three grooves 22 may be provided, wherein the grooves 22 also different can be wide.
  • Spring packs 21 can serve as Justiervole.
  • the Braking device 6 can with one or more support bodies 20 be provided.
