Definitions

  • the present invention relates to an elevator system.
  • the invention relates to a device with which a moving body to be displaced on a guide rail can be guided and braked in an elevator system.
  • An elevator system usually includes several moving bodies which are guided by at least one guide rail in order to prevent them from lateral, i.e. essentially horizontal, movements.
  • the driving body is usually an elevator car and often at least one counterweight.
  • a traveling body is generally moved vertically between different levels.
  • several guide devices are usually provided on the driving body, for example in the form of guide shoes, which move along the vertical guide rail and can be supported on it in the lateral direction.
  • the elevator system In order to be able to brake vertical movements of the traveling body, the elevator system generally has a braking device.
  • a braking device can be designed as a so-called safety brake in order to be able to stop the vertical movement of the driving body as safely, quickly and efficiently as possible in emergency situations such as a free fall.
  • the braking device can have a braking element which is pressed against the guide rail when the braking device is activated and can therefore bring about a desired braking force on the driving body coupled to the braking device due to the friction generated here.
  • Guide rails in elevator systems are usually not perfectly aligned parallel to a desired travel path of a moving body, for example due to manufacturing and/or installation tolerances.
  • at least locally limited portions of a guide rail can not be linear and perfectly vertical, but curved and/or obliquely aligned.
  • lateral deviations in the position of a guide rail can occur, particularly in very tall elevator systems a target position of up to several millimeters. The deviations can vary along a longitudinal extent of the guide rail.
  • relatively high speeds are typically required when moving the moving body, so that lateral deviations of the guide rail from its target position can lead to a rapid, jerky lateral displacement of the moving body.
  • the guide devices on elevator cars of elevator systems are usually designed to be elastically mounted.
  • the guide devices can yield to the deviations of the guide rail from its target position to a certain extent, at least within a predetermined tolerance range, without exerting strong and / or in particular jerky forces in the lateral direction on the elevator car.
  • the design of the braking device of an elevator system must also take into account the possible lateral deviations of the guide rail from its target position.
  • the braking device is usually designed in such a way that its braking element is located laterally away from the target position of the guide rail by a sufficiently dimensioned activation distance as long as the braking device is not activated.
  • the activation distance is chosen so that the braking element does not come into contact with the guide rail, even with maximum expected lateral deviations of the guide rail from the target position, as long as the braking device has not been activated.
  • the relatively large activation distance to be chosen in conventional braking devices means that the braking element, if the braking device is to be activated, must first be displaced over the entire activation distance until its surface comes into contact with the guide rail and a braking effect can be generated.
  • an actuator that displaces the braking element must be suitably designed in order to be able to overcome such a large activation distance.
  • the braking element needs to be moved over a large area Activation distance requires a certain amount of time, which can have a negative effect on the reaction time of the braking device or ultimately on the braking distance.
  • WO 2004/033353 A1 a device for combining elevator guidance and safety braking is described.
  • EP 3 141 511 A1 a housing arrangement for a safety actuation device is described.
  • EP 1 400 476 A1 a safety gear for elevators is described.
  • EP 3 141 511 A1 discloses a device according to the preamble of claim 1.
  • a device for guiding and braking a moving body to be displaced along a guide rail which has a holder, a guide device and a braking device.
  • the holder can be attached to the chassis. Managers can be transferred between the guide device that can be guided on the guide rail and the traveling body.
  • the guide device is configured to move along at least one surface of the guide rail in the longitudinal direction of the guide rail.
  • the guide device is held and mounted on the holder in such a way that the guide device can be elastically displaced relative to the holder in a direction transverse to the longitudinal direction of the guide rail by at least a predetermined tolerance distance and thereby transfers the guides to the holder.
  • the braking device has a carrier and a braking element and is configured to move the braking element between a deactivated configuration in which a braking surface of the braking element is laterally spaced from the guide rail and an activated configuration in which the braking surface of the braking element can be placed against the guide rail , reversible by an activation distance in one To shift direction transverse to the guide rail.
  • the carrier of the braking device is rigidly coupled to the guide device, so that the carrier of the braking device follows lateral displacements of the guide device relative to the holder.

  • a tolerance distance within which the guide device can follow deviations of the guide rail from its target position should be relatively large.
  • jerky movements of the driving body should be avoided and thus a high level of driving comfort for passengers should be achieved.
  • the proposed device is intended to make it possible to brake the driving body efficiently, quickly and safely.
  • a moving body can be understood to mean both an elevator car and a counterweight.
  • a high level of ride comfort is particularly advantageous in elevator cabins.
  • Efficient, fast and safe braking is beneficial for both elevator cars and counterweights.
  • the two objectives mentioned are in some ways contradictory.
  • the tolerance distance with which the guide device can follow the guide rail on local lateral deviations should be as large as possible.
  • the braking devices are usually designed and arranged in such a way that their activation distance, by which their braking elements must be laterally displaced in order to produce a braking effect by resting on the guide rail, is greater than the tolerance distance of the guide device.
  • the greater this activation distance the more difficult it is to move the braking elements quickly and efficiently over this activation distance in order to be able to brake the driving body.
  • the activation distance can be smaller, for example by more than 10%, preferably more than 50% or even more than 80%, than the tolerance distance.
  • the tolerance distance of the guide device can preferably be greater than 3 mm, more preferably greater than 4 mm or even greater than 5 mm or greater than 10 mm, whereas the activation distance of the braking device can preferably be less than 3 mm, more preferably less than 2 mm can.
  • the guide device can follow lateral deviations of the guide rail along which it is supposed to run with great tolerance, but the braking device only needs to shift its braking element over a short activation distance in order to be able to quickly and efficiently trigger braking of the driving body.
  • the holder, the guide device and the braking device of the proposed device should be designed and arranged in a predetermined manner and interact with one another.
  • the holder should primarily be configured to be attached to the driving body and thereby fix the other components of the device to the driving body.
  • the holder should be sufficiently mechanically stable to be able to accommodate managers and transfer them to the driving body. For example, leaders can appear in a range from a few Newtons to a few kilonewtons for a short time.
  • Such guides can, for example, be exerted by the guide device on the holder if the guide device is, for example, suddenly displaced laterally in order to follow local position deviations of the guide rail.
  • the holder can be designed as a largely rigid structure and a structure that can be rigidly attached to the driving body.

  • the guide device is held and mounted on the holder in such a way that it can be moved transversely to the longitudinal direction of the guide rail relative to the holder at least over the predetermined tolerance distance.
  • a mechanical coupling between the guide device on the one hand and the holder on the other hand should be designed in such a way that the relative displacement between the two components can take place elastically, that is to say without plastic and therefore irreversible deformations of those used for such a coupling Components. Furthermore, the mechanical coupling between the guide device and the holder should be designed such that the managers can be transferred from the guide device to the holder.
  • the guide device can therefore be displaced along the guide rail and elastically follow any lateral deviations at least up to the predetermined tolerance distance. Forces caused in the lateral direction can be transferred elastically to the holder and thus to the driving body in order to guide them in their vertical movement on the one hand, but on the other hand to avoid causing jerky lateral movements.
  • the braking device is configured, as long as it is not activated, to have no significant influence on the displacement of the driving body, but to cause braking, in particular possibly emergency braking, of the driving body when the braking device is activated.
  • the braking device has at least one carrier and one braking element.
  • the braking element can be displaced relative to the carrier.

  • the lateral distance between the braking surface of the braking element of the braking device and the opposite surface of the guide rail, i.e. the activation distance of the braking device, can be significantly smaller than the tolerance distance by which the braking device together with the guide device can be elastically displaced laterally relative to the holder.
  • the guide device has at least one roller which is rotatable about an axis and which is configured and arranged in such a way that the roller can be moved in a rolling manner with a lateral surface along the surface of the guide rail.

  • the bearing rail is articulated at one of its ends to the rest of the carrier 43, so that the movement in the joint leads to a movement of the bearing rail in the direction 37.
  • the electric actuator 57 can move the bearing rail laterally, ie in the direction 37 transverse to the longitudinal direction 35 of the guide rail 7, towards the guide rail 7.
  • the actuator 57 can move the braking element towards the guide rail 7 by briefly lifting the sliding surface 51 from the counter-sliding surface 53.
  • the braking element 45 can have a groove which opens the braking element 45 towards the actuator 57.
  • the actuator 57 presses in the lateral direction on the bottom of the groove in the braking element 45.
  • the groove is designed in such a way that it creates the required space in the braking element 45, so that the braking element 45 remains movable along the longitudinal direction 35 when the electric actuator 57 in an extended state at least partially protrudes into the braking element.
  • the actuator 57 can displace the braking element 45 in the longitudinal direction 35 of the guide rail 7, with its sliding surface 51 sliding along the counter-sliding surface 53 of the carrier 43 and thus also being moved laterally towards the guide rail 7.
  • the device 9 described here for guiding and braking the moving body 2 offers the possibility of using the elevator car 3 comfortably on the one hand to guide the guide device 21, which can be moved elastically over the tolerance distance, during its vertical displacement along the guide rail 7.
  • the braking device 41 of the device 9 with its braking element 45 or its braking elements 45 can be moved past the guide rail 7 with very little lateral play in the deactivated configuration, since the braking device 41 is rigidly coupled to the guide device 21. Accordingly, the braking device 41 can be activated quickly and effectively by engaging the braking element 45 or the braking elements 45 towards the guide rail 7 over an activation distance 49 that is smaller than the tolerance distance 39.
