Definitions

  • the invention relates to a device for securing, in particular the crash, of elevators or lifting devices according to the preamble of claim 1 and a method for hedging, in particular of the crash, of elevators or lifting devices according to the preamble of claim. 8
  • the invention is therefore based on the object to provide a device and a method of the type mentioned, by which the mentioned disadvantages do not occur or to a lesser extent.
  • a scanning element is provided, which is offset by the proper movement of the elevator or the lifting device in a movement along a predetermined path. This can be done, for example, by guiding the scanning element along a contour element. In normal operation, this scanning element will not leave the predetermined path. However, if the elevator exceeds a certain speed, which can be specified by the construction of the device, in particular geometry of the predetermined path and the inertia of the sensing element, so the sensing element leaves due to the inertia of the predetermined path, whereby a brake or Safety gear is triggered.
  • the brake or safety device is integrated into the device according to the invention.
  • a simple mechanical solution for monitoring the speed is specified, which makes it possible to trigger a brake or safety gear at a predetermined speed by the construction.
  • the proposed solution is thus equipped with an integrated speed limiting function.
  • the device requires only a small amount of installation space, and this only in an already envisioned elevator shaft. Installations in the area of the shaft head or the shaft pit are not required.
  • the device according to the invention also works without auxiliary power, the omission of which can consequently not be a reason for a malfunction.
  • a scanning element 3 which can be embodied, for example, as a roll, follows in normal operation a web which in this concrete exemplary embodiment is predetermined by the profile 2.
  • This profile 2 is normally stationary, for example in the elevator shaft, assembled. It preferably extends over the entire path of travel of the elevator or the lifting device or a counterweight possibly present for load balancing.
  • it is a contour element, for example a wave profile or a profile with a different periodic contour.
  • the scanning element 3 is usually carried by the load-receiving device of the elevator or the lifting device or of a possibly existing counterweight.
  • the profiling of the profile 2 and the sensing element 3 are structurally coordinated so that in normal operation, which is characterized by the failure to exceed a defined speed, that scanning element 2 remains largely in contact with the profile.
  • a suitable pressure device 6, for example a return spring, is provided for this purpose.
  • the sensing element 3 loses contact with the profile 2 due to inertia. This leaves it is his train scheduled in regular operation. Leaving the predetermined path is used to trigger a catch or brake device.
  • An alternative embodiment of the invention provides, instead of a purely mechanically acting on the sensing element 3 profile 2, a device that the web the scanning element 3 pretends.
  • This may be a field based on another, preferably electromagnetic or magnetic interaction with a, preferably periodic, potential profile along the travel path.
  • a suitable scanning element 3, for example a magnet is set into a forced oscillatory motion when the potential field is traversed by the interaction with the field.
  • This embodiment also provides that the components are matched to one another in such a way that, when a defined speed is exceeded, a trajectory of the scanning element 3 provided for the controlled operation is left by the latter due to the inertia of mass. This is also used to trigger a catch or brake device.
  • the related safety gear consists of an articulated lever 4 and a latching element 5, which engages in a, in the illustrated case stationary and preferably over the entire travel of the elevator or the lifting device or a load balance possibly existing counterweight extending, catching profile 1.
  • a catching profile 1 another suitable catching element may be used, for example, recesses may be provided in suitable parts of the building structure or the elevator construction.
  • a further advantageous embodiment provides a plurality of catch elements along the travel path.
  • the sensing element 3 is attached to the articulated lever 4.
  • the catch profile can be designed as a separate component or a separate module or as a composite component with the profile 2.
  • the device according to the invention can be designed so that it can be used when unloading the safety gear, e.g. at the resumption of the regular operation after the elimination of the cause of the crash, without further action returns to the normal operating state. Under certain circumstances, this is a suitable device provided, if necessary, the pressure device 6 can also take over this function.
