Definitions

  • the invention relates to a catching device for a carriage of a sloping or vertical elevator guided on running rails, each with a cam which engages by means of self-locking friction on each running rail, consists of an eccentrically mounted cam, held at a stop and biased in its direction of action, the axis of rotation of which on a sliding frame opposite that Main frame of the carriage is guided so that it can be pushed, and each with a brake block as an anti-tamper device, with a triggering device in the event of, for example, a broken rope and / or exceeding a predeterminable maximum speed of the carriage for engaging the cam plate biased in the effective direction on the associated running rail and with at least one shock absorber for damping the relative movement between the sliding frame and the main frame when the cams engage the running rails.
  • Rail-bound inclined or vertical elevators are to be fitted with safety brakes according to international standards in order to bring the carriage or car to a standstill in emergencies, such as a broken rope or exceeding the permissible maximum speed.
  • Friction brakes are predominantly used as safety brakes, which in such cases, after being triggered by suitable devices with friction linings, slide on the running rails.
  • the running rails generally consist of structural steel profiles with unprocessed surfaces and can be partially corroded or iced up, especially in the case of elevators installed outdoors, which has a strong influence on the momentary coefficient of friction on the friction pairing and thus the braking distance.
  • blocking devices as safety brakes and / or speed limiters, which grip the running rails in a force-locking manner or even engage in a form-fitting manner in the rail guide, for example in accordance with DE-GM 77 27 207 a safety catch device with a spring-preloaded device Eccentric as a cam disc, which clamps the carriage against a brake block on the running rail, self-locking.
  • Such blocking devices have practically no appreciable braking distance, if they grip this is associated with correspondingly high braking decelerations and with undesirable noises.
  • a safety brake and a speed limiter for a rail-guided vertical elevator with the generic features mentioned above have become known from DE-PS 119 240.
  • a catching device two rotatable eccentric disks connected to each other by a shaft are provided, which engage the associated running rail without sliding friction and press them against a brake block as an anti-tamper device; on each eccentric disc, the axis of rotation can move in a pushing manner transversely to the running direction of the car and is supported on the car frame by a spring or a hydraulic buffer.
  • the stroke on the eccentric disc corresponds directly to the transverse damping path, since the eccentric disc does not act in a blocking manner on the running rail, but rather rolls on it during braking; the damping path is therefore quite short, so that the braking delay when gripping the safety gear is correspondingly high, because the inclination of the curve on the eccentric must be chosen small so that its engagement on the running rail remains in the area of self-locking friction and less than the full for the damping path Revolution of the eccentric disc is available.
  • a spring can also be used as a damping device for the kinetic energy of the car, since the eccentric disc cannot swing back.
  • the invention has for its object a safety brake and / or a speed limiter for a carriage guided on rails of an inclined or vertical elevator with one of the stroke of the safety gear completely to create independent damping path, which can thus be dimensioned for the respective application.
  • the sliding frame is guided in a pushing manner on the main frame in the running direction of the carriage and that the safety device engages in a blocking manner on the running rails.
  • the two eccentrics that are prestressed in the effective direction come into engagement with the respectively associated running rail after they have been triggered.
  • the friction pairing between the eccentric and the running rail is self-locking, so that the eccentric rolls on the rails without sliding until the clearance on the brake block forming the tamper-evident block is overcome; so that the slide frame is clamped and blocked on the rails, so that the main frame of the carriage including the platform runs against the shock absorber; the greater the weight, the greater the braking force.
  • the invention results in a braking delay corresponding to the damping path until the carriage comes to a standstill. Sliding friction on the running rails does not occur at all in the invention, so that the desired braking or damping path can be predefined and dimensioned in a suitable manner, regardless of the surface condition of the running rails, for the respective use of the elevator.
  • a spring preload of the eccentric is possible in principle.
  • a drop weight fixedly attached to the eccentric is used, because otherwise the catching device will not function in the event of a spring break; the spring force required for triggering also need not be monitored.
  • the triggering device on each eccentric consists of one trigger guard, at the stop of which the associated eccentric abuts and is kept out of engagement during normal travel, and both trigger guards are non-rotatably connected to one another via a trigger shaft connected.
  • any release pivots on the release shaft and levered out both trigger guards at the same time In an emergency, both eccentrics always come in at the same time, and the carriage is prevented from being skewed.
  • a slack rope release is provided in the invention, which consists of a rocker pivotally mounted on the main frame of the carriage in a swivel joint, on the levers of which the two traction cables engage, and two push rods pivotably mounted on the lever ends of the rocker in swivel joints attack the release shaft so that it can pivot in order to trigger the safety gear and blocking device in the event of a rope break.
  • a speed limiter is provided in the invention as a second trigger device, which consists of a sensor wheel rotatably mounted on the slide frame on each running rail and at least one radially inwardly biased, sickle-shaped centrifugal weight on the sensor wheel that is pivotally spring-loaded and that with a pin via a trigger lever on the release shaft engages in a swiveling manner in order to release the catching and blocking device in the event of the maximum speed of the carriage being exceeded.
  • two opposing centrifugal weights are provided on the speed limiter, which are inevitably connected to one another by means of a coupling via two further rotary joints to form a joint parallelogram, so that they can only move synchronously in the radial direction.
  • the two flyweights are expediently arranged in a housing ring which is connected in a rotationally fixed manner to the sensor wheel and is closed with a cover on the side facing away from the sensor wheel, and slots are arranged in the cover which are penetrated by the flyweight-resistant pins; the rotating centrifugal weights are thus protected on all sides by the housing.
  • At least one leaf spring is fastened at one end to the housing ring of the speed limiter, the other end preloading the centrifugal weights radially inwards, and the housing ring together with the leaf spring is for determination the release centrifugal force rotatably held in the circumferential direction between the cover and the sensor wheel.
  • two opposing leaf springs are provided, each of which acts on an associated centrifugal weight.
  • the carriage denoted overall by 1 of a rail-bound, inclined elevator operated by a cable winch is shown; the two pulling ropes acting on the carriage 1 are denoted by 7 in FIG. 1a.
  • the Carriage 1 consists of a main frame 11, on which a platform 13 is supported at an angle via a support 14 at an angle ⁇ .
  • the rails 2 shown horizontally in Figure 1 run with respect to the flat horizontal on a slope at the angle of inclination ⁇ , so that the platform 13 is then horizontal, on which a car, not shown in detail, is built for people or load transport.
  • the carriage 1 has 11 on the main frame two axes 15, on each of which a two-armed rocker 16 is pivotally received in the middle; at the ends of each rocker 16 two impellers 17 are mounted.

  • a sliding frame 1 1 is received in a sliding manner in the running direction A and is supported on both sides by shock absorbers 6 on the main frame 1 1.
  • a catch and blocking device designated as a whole by 3 is attached above each running track 2, and can be brought into engagement with the running tracks 2 von by two trigger devices 4 and 5 acting independently of one another:

  • Each eccentric 31 is biased by a drop weight 33 attached to it in its effective direction W for engagement with the running rail 21 and is as long as the trigger guard 36 holds it at its stop 361, with a certain distance above the upper leg 211 of the running rail U profiles 21.
  • the effective surface of the eccentric 31 is formed by a curve, the slope of which is designed in the circumferential direction for self-locking friction when engaged with the upper leg 211 of the running rail 21.
  • a brake block 3 2 fixed to the slide frame 1 2 provides the upper leg 2 1 1 of the running track 2 1 with a encompasses the corresponding recess; in the disengaged position shown in FIGS. 2 and 3, both on the eccentric 3 1 and on the brake block 3 2 opposite it, a certain clearance L is provided for the upper leg of the U profile 2 1.
  • Both trigger guard 36 are rotatably connected to each other via a trigger shaft 36. If the trigger shaft 36 is rotated, for example by actuating the trigger lever 35 shown in FIGS. 2 and 3, firmly connected to the trigger bracket 36 and trigger shaft 36, then the trigger bracket 36 on both eccentrics 31 simultaneously disengages and the drop weight 33 rotates the eccentric 31 in its effective direction W for engagement with the running rail 21.
  • the slack rope release is best seen in Fig.1a) and is generally designated 4; Furthermore, a speed limiter, generally designated 5, is arranged on each of the two catching and blocking devices 3, which responds to the catching and blocking device 3 independently of the slack rope release 4 when the carriage 1 in the direction of travel A downwards exceeds its predetermined maximum speed, bswp. because of a cable winch brake failure.
  • the slack rope release 4 shown in Fig.1a) consists of a 411 pivoted centrally on the main frame 11 rocker 41 mounted in the pivot joint. At the opposite levers of the rocker 4 1, the two pull cables 7 attack. At both lever ends of the rocker 41 push rods 42 are pivotally mounted in pivot joints 421, each of which engages via slots 422 on a pin 341 of the trigger shaft 34 of the catching and blocking device 3. The length of the slots 422 in the push rods 42 is matched to the damping stroke D during braking. In the event of a cable breakage of one of the two pull cables 7, the taut other cable 7 pulls the rocker 4 1 into the pivoted position shown in dashed lines in FIG. 1a), as a result of which the trigger shaft 3 'on its pins 3' 1 is rotated via the push rods 4 2, whereby the trigger guard 3 ' two eccentrics 3 1 come out of engagement and the eccentrics 3 1 engage on the running rails 2 1.
