Definitions

  • the present invention relates to a device and a Vertical displacement prevention method and Vertical vibrations on load handling devices of vertical conveyor systems during its standstill, which is the desired one Achieve the effect that the load handler during the floor stops by means of a braking device Friction is held on its guide rails and if there is a corresponding control command this Friction is canceled.
  • EP 0 346 195 discloses an electromagnetically actuated caliper brake which is designed, inter alia, to connect the car or the counterweight of an elevator to its guide rails in a friction-locked manner on control command.
  • the brake contains two two-armed caliper levers with a common center joint, the axis of which is fixed to the cabin or the balance weight.
  • the clamp sides of the caliper levers are covered with brake pads and encompass the guide bar of the cabin or counterweight guide rails.
  • the opposite drive ends of the caliper levers are spread by a compression spring, which creates the clamping force between the brake pads and the web of the guide rail on the other caliper side.
  • a tension magnet is arranged concentrically to the expanding compression spring, which overcomes the force of the compression spring when the current flows and thus opens the brake caliper.
  • the disclosed braking device is intended in particular as a holding brake for counterweights or cabins of linear motor-driven elevators and the claims essentially relate to the design of an integrated damping element for preventing switching shocks and switching noises caused by the pull magnet.
  • load suspension devices are prone to vertical vibrations during standstill, which are excited by the stopping process, by changes in load or by the level compensation processes described.
  • Vertical displacements as well as vibrations of the load handler in passenger lifts can cause unpleasant sensations to the point of being frightened by the passengers.
  • the level differences between the cabin floor and shaft door sill of a passenger elevator can cause tripping accidents for passengers getting on and off.
  • the situation described can be improved by frictionally holding the load handler to its Guide rails can be reached.
  • the present invention has for its object a to create a braking device attached to the load suspension device, the vertical displacement problems described above and vertical vibrations of the load handler solves without compromising driving comfort, in particular without opening the brake to continue the load handler to cause a jerk.
  • the attachment or use of the braking device according to the invention which is attached to the load suspension device and has an integrated recording of the holding forces, has significant advantages. Measuring the holding forces directly on the braking device is technically advantageous because it enables the effectively existing holding forces to be precisely recorded and compensated for, while all indirectly acting methods for relieving the brake involve several sources of error.
  • a perfect brake relief before starting to continue is not generated here by generating a control system from a torque detection when stopping and a measurement the payload difference calculated during the floor stop Preload torque enabled by the drive unit, but by having this torque through before starting the drive unit built up continuously so far until one by the load measuring sensors on the load suspension device attached brake device formed measuring bridge is balanced, d. H. until this braking device is perfectly relieved. Deviations due to friction and due to errors in the payload measurement as well as by Inaccuracies in the generation of a calculated one The corresponding torque is the default value for this method locked out.
  • the load suspension device according to the invention attached braking device the usual holding brake on the Replace drive unit, but also an operation with both braking devices is possible.
  • the braking device attached to the load suspension device the holding forces recorded in the up and down direction
  • Load situations provide enough information to pre to continue driving this brake device completely relieve pressure and thus enable a smooth start.
  • the detection of the holding forces in the up and down direction is required for two reasons.
  • the on Load suspension device attached braking device for example due to boarding or disembarking passengers, in different ways Direction charged.
  • the drive unit is the direction of loading on the Load suspension device attached braking device depends on whether the weight of the load handler and current Payload greater or smaller than that of the counterweight is.
  • the integration of the measuring elements in the unit of the load suspension device attached braking device allows one simple, sandwiched with other cabin components combined attachment of this device to the cabin.
  • a toggle mechanism has the advantage of being powerful of the lifting mechanism with simple means in many cases is strengthened and no permanent holding force in the braking state the lifting mechanism is required. It is therefore, too taking into account power failures, lifting mechanisms applicable, which are activated without a preloaded spring for a short time Closing and opening strokes work such.
  • An important advantage of this invention is that the future use of suspension elements made of plastic fibers (e.g. aramid fiber ropes or flat belts) in Increased mass of problems to be expected regarding vertical displacements and vibrations during floor stops by using the load suspension device according to the invention attached braking device can be avoided can.
  • plastic fibers e.g. aramid fiber ropes or flat belts
  • Fig. 1 is a plan view of an inventive Cabin brake device 1 shown. On the left you can see a cabin guide rail 2 common in elevator construction which the braking device acts.
  • the cabin brake device 1 essentially consists of a cuboid housing 3, a brake caliper support 4 fixed therein with two brake caliper joint bolts 5, the brake calipers 6 with brake caliper hub 6.1 and brake lining carrier 6.2, the brake linings 7, a toggle lever mechanism 8, as a lifting magnet, hydraulic cylinder or Lifting spindle motor designed lifting mechanism 9 and a compression spring 10.
  • it contains strain gauges 11 with which the holding forces of the brake calipers are recorded.
  • the holding effect of the cabin brake device is achieved in that the compression spring 10 spreads the drive levers of the brake calipers 6 which can be pivoted about the brake caliper joint bolts 5 via the toggle lever mechanism 8 and thus presses the brake-side lever thereof with the brake pads 7 against the running surface of the guide rail.
  • the toggle lever mechanism greatly increases the spring force.
  • the drawn position of the cabin brake device corresponds to the state in which it holds the cabin frictionally on the guide rails 2.
  • the cabin brake device is released in that the controllable lifting mechanism 9 overcomes the biasing force of the compression spring 10, brings the toggle lever mechanism 8 into a bent position, thereby relieving the brake calipers 6 and moving the brake pads at a sufficient distance from the guide rail 2.
  • a device which enables the effective length of the extended toggle levers to be adjusted by means of screws.
  • FIG. 2 shows a vertical section through the cabin brake device 1.
  • the cabin guide rail 2, the base plate 12 and the cover plate 13 of the housing 3, the brake caliper support 4 with the brake caliper joint bolts 5, the brake caliper 6 with brake caliper hub 6.1 and brake pad carrier 6.2 are shown.
  • a cross section through the toggle mechanism 8 and the lifting mechanism 9 and the compression spring 1o The mode of action of the detection of the holding forces on the cabin brake device according to the invention can be seen here.
  • the housing 3 contains one with it here connected metallic guide carrier 14, the two plate-shaped Boom 15 has two bores 16 each, which as play-free guides for the brake caliper joint bolts 5 serve.
  • the arms 15 act as a parallelogram guide for these bolts, which are Cross pin 17 fixed to the brake caliper hub 6.1 of the brake caliper 6 connected and on the other hand axially via piezoelectric Pressure sensors 18 against the base plate 12 and the cover plate 13 are supported.
  • Fig. 4 shows the application and installation of a car brake device according to the invention in a conventional elevator system. Shown are an elevator shaft 20 with car guide rails 2 installed therein, a machine room 21 containing a drive unit 22 with traction sheave 23, an elevator car 24 with car frame 25, a counterweight 26 and suspension means 27 which connect and support the car and the counterweight and are in turn driven by the traction sheave 23. Attached to the cabin frame 25 are roller guide units 28 for guiding the cabin 24 on the cabin guide rails 2, safety catch devices 29 and the cabin braking devices 1 according to the invention. These components are designed in such a way that they can be flanged to one another and to the cabin frame by means of suitable connecting parts. With this technology, in the case of very heavy cabins, two or more cabin braking devices can also be installed one below the other.
  • FIG. 5 shows a preferred arrangement of two cabin braking devices 1, in which a common compression spring 30 via a connecting rod 32 and the toggle mechanisms 8 both braking devices are actuated and a common, on the cabin frame attached lifting mechanism 31 against this the compression spring 30 releases, which ensures synchronous function and one-sided braking is excluded.
