Definitions

  • Different braking forces here means the braking force and thus the deceleration in the event of an emergency stop in the upright position for physical and human reasons Compatibility in the up direction should be significantly smaller than in the down direction.
  • a technical article in LIFTREPORT (Issue 5/91, page 38) describes one in both directions with different braking force acting safety brake BFx3.
  • One over cable and Rope wrap trigger device is with one Eccentric disc on each side of the cabin.
  • the Eccentric discs have two flats, which as Act and the rotary movement when triggered to stop.
  • the two Eccentric discs depending on the direction of travel, clockwise or Turned counterclockwise up to these stop surfaces.
  • the with the rotation increases the radius of the eccentric discs an opposite compression spring together, with which the Braking effect occurs.
  • the angle of rotation is smaller than in the downward direction and this is how, as desired, the Braking effect and thus the deceleration in the upward direction smaller.
  • the ratio of the two braking effects in the Aufund the downward direction to each other is through the given geometric dimensions of the eccentric discs and can cannot be changed afterwards.
  • the braking force is only general adjustable. Due to the rolling path of the eccentric discs there is a relatively long reaction path up to the full one Braking effect.
  • the invention is characterized inter alia by characterized in that as braking force generating element at least one up and down tiltable seesaw is available for catching in up or down Downward driving direction different braking forces generated. A short reaction path up to is also advantageous full braking effect.
  • the design with only one existing Brake shoes and actuators for both directions of travel is structurally simple and inexpensive to manufacture.
  • the braking force in the up and down directions is uneven generating device is as a spring-supported two-point bearing designed for the rocker that can be tilted up and down.
  • the spring-supported point or swivel bearings are counter Spring-loaded articulated cups formed with defined standby position.
  • the rocker points in the standby position of the Brake safety device, joint balls resting in joint sockets on.
  • the brake shoes are in the standby position by one Retention spring pressed against the stops that after the Brake safety device also serve as stops for the rockers.
  • the seesaw is engaged by one that engages in the seesaw Driver pin actuated, which with any Tripping device is connected.
  • the brake shoe is articulated to the rocker.
  • the rocker can be tilted over the dead center, which provides greater security against the automatic Falling back results.
  • the tilted rocker has a stop defined End position.
  • the brake safety device can have one or two rockers.
  • a brake device with a rocker has a fixed and a movable brake shoe.
  • a second rocker can be supported on fixed abutments.
  • the trigger device can be used as a simple lever mechanism Diagonal bracket and rope coupling to be formed.
  • a fulcrum of the lever mechanism is with a release shaft for the triggering of the parallel safety gear on the coupled on the other side of the cabin.
  • the brake safety device shown in Figure 1 consists in essentially from a cross-movable, in a not shown cabin support structure mounted, base plate 8, on which a stop block 23 on the left and a right Spring block 22 is arranged. Furthermore, to the left of one Guide rail 7 between a brake shoe 14.1 with a brake pad 15.1 and the stop block 23 a triangular in the basic form Rocker 1.1 available.
  • the rocker 1.1 has a lower and upper Joint ball 2.1 / 2.2, each in one in the stop block 23 worked out upper and lower fixed socket 12.1 / 12.2 rest. At the top of the rocker 1.1, this is by means of an articulated bearing 3.1 operatively connected to the brake shoe 14.1.
  • the joint balls 2.1 / 2.2 and the spherical bearing 3.1 form the Corner points of an approximately isosceles triangle.
  • the practical executed outer shape of the seesaw is not to the shown form bound and can be used within wide limits vary as long as their intended function is guaranteed.
  • the rocker In the standby position shown, the rocker is 1.1 by means of one in the stop block 23 and on the rocker 1.1 attached retaining spring 5.1 held.
  • the brake shoe 14.1 is in this position on the back and one on top Double stop 13.1 / 13.2 loosely on so that during normal Lift operation no contact with the guide rail 7 takes place.
  • An approximately on the median of the Rocker triangle existing slot 20.1 serves the actuating Engagement of, for example, a round bolt, Driver 4.1.
  • the driver 4.1 is located on a Release lever 19, which is part of a T-shaped release rod 18th forms, the latter above and below with a governor rope 16 is coupled.
  • the Movable joint pans 6.1 / 6.2 rest in a defined position Thrust washers 9, which are in the standby position Brake safety device from an upper and lower compression spring 10.1 / 10.2 are pressed against an inner stop.
  • the upper Compression spring 10.1 is in an upper spring chamber 17.1 and lower compression spring 10.2 in a lower spring chamber 17.2 built-in.
  • the upper compression spring 10.1 is by means of an upper one Adjusting screw 11.1 variable via the second thrust washer 9 prestressed.
  • the lower compression spring 10.2 is independent of the upper, by means of a lower adjusting screw 11.2 over the second thrust washer 9 variably biased.
  • the brake safety device according to the invention is shown in FIG engaged position with a brake catch in the up-driving direction shown.
  • the same functional sequences are used here with a brake catch in the down-driving direction, but with Tilting movements of the rockers 1.1 / 1.2 down.
  • the prestressed lower compression spring 10.2 compressed by the amount X.
  • the lower spring 10.2 with a possibly weaker dimension the set screw 11.2 less biased what accordingly results in smaller delay values.
  • FIG. 4 shows a variant for the triggering device shown in the form of a lever mechanism 28.
  • the first Angle lever 25 is rotatable about a pivot point 25.3 and carries the driver at the end of its horizontal leg 25.1 4.2.
  • the vertical leg 25.2 is with its upper end hingedly connected to a connecting strap 27 which in turn with its other end with the lower end of the vertical leg 24.2 of the second angle lever 24 also is articulated.
  • the second angle lever 24 is rotatable about a pivot point 24.3 and carries at its end of the left horizontal leg 24.1 the driver 4.1.
  • the horizontal leg 24.1 of the second angle lever 24 has also as a connection to a limiter rope 16 Rope clutch 26 on.
  • the inconsistent rotational movements of the both levers 24/25 in the event of a brake release cause one synchronous up or down movement of the two drivers 4.1 and 4.2 and a correspondingly common tilting in the same Direction of the two rockers 1.1 and 1.2.
  • the fulcrum 24.3 is advantageous at the end of a connecting shaft, not shown arranged which, when triggered, the second in parallel working safety gear on the other side of the Cabin operated.
  • Geometric dimensions of the rocker 1 can this loss of path partially or fully compensated. This can for example, by an increased distance between the Joint balls 2.1 and 2.2 and the movable joint socket 6.1 and 6.2, and possibly a slightly different height of the triangle can be achieved.
  • the function of the simplified safety gear applies Initial friction of the movable brake shoe 14/15 the guide rail 7, because with a larger base distance in Triangle also generate a larger vertical tilting force got to.
  • the simplified trigger bar is used as the trigger device 21 or the angle lever 24 applicable.
  • Safety gear are simplified and schematic shown. They are primarily intended to be the solution principle and the functions in an easily understandable and descriptive way show. The practical execution can do more in detail or differ less from the depictions shown. For example, for the rockers 1 / 1.1 / 1.2 additional possibly inevitable guide elements provided. Further the practical version will have separate stops for the Brake shoes 14/15 when the Have safety gear, which the relatively high absorb vertical deceleration forces when braking. Thereby the spherical bearings 3 / 3.1 / 3.2 only the horizontal Take up pressure forces.
  • a compression spring 10.1 / 10.2 can be any permanently elastic Element with a suitable characteristic curve can be used.
  • Set screws 11.1 / 11.2 are mechanical or others Fuses are provided, which automatically adjust the Prevent set screws 10.1 / 10.2 reliably.
  • Retaining spring for the rockers 1 / 1.1 / 1.2 can replace them a spreading compression spring between the rockers 1 / 1.1 / 1.2 be provided. Points of attack for such a compression spring would be, for example, laterally led out bearing bolts Spherical bearing 3 / 3.1 / 3.2 suitable.
