Definitions

  • the invention relates to a sliding guide shoe according to the preamble of claim 1.
  • the invention also relates to a counterweight equipped with such sliding guide shoes.
  • the invention relates to an elevator installation.
  • Elevator systems for transporting people and goods contain elevator cars that can be moved up and down in an elevator shaft.
  • the elevator cars can be moved in the vertical elevator shaft via suspension means, for example in the form of suspension ropes or suspension belts, by means of a drive unit.
  • the elevator installation generally includes at least one counterweight, which is moved in opposite directions in the elevator shaft.
  • the elevator car and the at least one counterweight run in guide rails.
  • Guide shoes are usually used to guide elevator cars and counterweights, and the guide shoes can be designed as sliding guide shoes or roller guide shoes.
  • Known and common are, for example, multi-part sliding guide shoes comprising a guide shoe housing and insert, such as are known from DE 203 15 915 U1. Such or similar sliding guide shoes are attached to vertical supports of counterweight frames. Such an arrangement with a counterweight frame and sliding guide shoes attached to it is shown, for example, in EP 3 199 483 A1.
  • WO 2014/027399 A1 relates to a further counterweight which is equipped with sliding guide shoes for guidance.
  • the sliding guide shoe for an elevator system for transporting people or goods is used to guide an elevator car or a counterweight along a guide rail extending in the direction of travel or longitudinal direction.
  • the sliding guide shoe includes a guide element with a guide channel.
  • the guide channel of the guide element is designed to complement a guide area of the guide rail and extends in the longitudinal direction.
  • This guide area which is formed, for example, by a web-like projection of the guide rail or a spring of the guide rail, can be accommodated in the guide channel.
  • the guide channel thus defines the sliding surface which, when the sliding guide shoe is installed in the elevator or is ready for operation, can make sliding contact with the guide rail in the guide area.
  • the sliding guide shoe can consist of the guide element described. However, it would also be conceivable for the guide shoe to include additional components in addition to the guide element, such as a lubricating device for oiling the guide rail.
  • the elevator car or the counterweight can have a support structure.
  • the support structure for supporting the elevator car can be, for example, a so-called catch or car frame.
  • the support structure can be a counterweight frame.
  • the support structure can have at least one recess for attaching the sliding guide shoe.
  • the guide element has a longitudinally extending engagement member which can be positively engaged in the recess of the support structure.
  • the guide element has a collar, which adjoins the engagement element with respect to the longitudinal direction, for encompassing the recess and for forming a stop for securing the guide element in the longitudinal direction in terms of position.
  • the collar is understood to be a flange-like elevation that forms a stop surface that is supported on the carrier structure with respect to the longitudinal direction when the guide part is inserted or placed in the recess.
  • a guide element provided with an engaging member and a collar is easy to assemble.
  • the guide element can be easily and yet precisely mounted on the support structure.
  • the guide element can be designed as a one-piece molded body made of a plastic.
  • the material for the shaped body can be a preferably rigid plastic material can be used.
  • the components of the guide element mentioned, ie the guide channel, the engagement member and the collar, are thus monolithically connected to one another.
  • Such a plastic molding can be produced inexpensively.
  • Another advantage is that the sliding guide shoe does not have to include any additional components; in particular, no larger metallic components such as a guide shoe housing are necessary.
  • the guide element can be designed as a disposable component and can be replaced easily and inexpensively after the end of its service life.
  • the guide element is particularly preferably an injection molded part. Such a guide element can be produced easily and with high precision.
  • the engagement element for the form fit is designed with a recess, which is advantageously open to the guide area of the guide rail provided for the guide, as a shell-like retaining pin that is inserted into the recess is inserted.
  • the engagement element can be designed in particular for the form fit with a U-shaped recess as a shell-like retaining pin.
  • the holding pin can have a semi-circular outer contour that is adapted to the round U-shaped recess.
  • the collar can then be a flange section protruding radially outwards.
  • the guide element can furthermore have a fastening section for fixing the guide element to the carrier structure. Thanks to the fastening section, it can be ensured that the sliding guide shoe can be connected to the elevator car or the counterweight directly and without additional components such as housing parts.
  • the fastening section is particularly preferably formed on the collar in the radial direction or at right angles to the longitudinal direction.
  • the fastening section can consequently also be part of the one-piece plastic molded body.
  • the guide element can have only one collar. However, it would also be conceivable to provide two collars. In this case, the guide element can have two opposite collars with respect to the longitudinal direction, so that the two collars enclose the carrier element from both longitudinal sides when the guide element is inserted into the recess. The distance between the collars, more precisely the distance between their stop surfaces, would then correspond to the thickness of the support structure in the area of the recess.
  • the fastening section can have a hole for a screw for screwing the guide element to the support structure.
  • a guide element that is plugged into or onto the carrier structure via the recess can be secured quickly and without great effort.
  • the hole can preferably be less than 10 cm, preferably less than 8 cm and particularly preferably less than 5 cm away from the groove bottom of the guide channel or from the closest area of the sliding surface of the guide channel. In this way, a guide element with a slim and compact design is created.
  • the hole is a through hole in which a metal bushing is inserted or otherwise arranged therein.
  • the metal bushing can be connected to the plastic part, for example by being sprayed onto the metal bushing.
  • the metal bushing ensures reinforcement of the attachment area for secure and durable positioning.
  • the guide element can have two segments, with the engagement member being assigned to a first segment and the collar being assigned to a second segment.
  • the stop surface formed by the collar can thus specify the separating line or plane between the two segments.
  • the second segment can further comprise a head part extending in the longitudinal direction. Thanks to the head part, there is a sufficiently long guide channel for optimal guide properties available.
  • the guide channel is consequently assigned to both segments or contained in both segments.
  • the lengths of the two segments can preferably be approximately the same—measured in the longitudinal direction.
  • the length L2 of the second segment is preferably greater than the length of the first segment.
  • a further aspect of the invention relates to a counterweight for an elevator system with a counterweight frame as a support structure for the counterweight.
  • the counterweight frame is used to hold weight elements.
  • weight elements in the form of metal plates or concrete weights stacked on top of one another can be arranged and in particular fixed therein.
  • the counterweight frame comprises at least one yoke and in particular an upper yoke and a lower yoke and beams connecting the upper yoke and the lower yoke. In the operational position, the yokes run in a horizontal direction, with the upper yoke and the lower yoke closing off the counterweight frame at the top and bottom, respectively; the beams mentioned run in the vertical direction.
  • the counterweight also has at least one sliding guide shoe and in particular a sliding guide shoe as described above, wherein the sliding guide shoe can be guided along a guide area of a guide rail designed as a projection or spring for guiding the counterweight.
  • the respective yoke has a horizontal plate on which at least one sliding guide shoe is attached.
  • the horizontal yoke plate has at least one recess into which the guide rail protrudes to form a slot guide and in which the sliding guide shoe is accommodated in a form-fitting manner. Thanks to this arrangement, no additional means are necessary to ensure groove guiding properties.
  • the slide guide shoe is easy to mount in the counterweight frame.
  • the yoke plate preferably has at least two recesses for accommodating sliding guide shoes, so that it can be guided on two sides. Particularly preferably, both the upper and the lower yoke each have two sliding guide shoes accommodated in recesses.
  • At least one of these recesses can be designed in a U-shape for receiving the sliding guide shoe in a form-fitting manner, as a result of which an open-designed recess can be obtained.
  • the sliding guide shoe can be a guide element with a have round groove bottom of a guide channel.
  • a round groove base is particularly suitable for guiding a guide area, formed by a fold, of a guide rail designed as a hollow profile.
  • Two recesses can be provided for each yoke on which sliding guide shoes are or will be mounted, with the recesses facing each other and with one of the recesses being arranged in the respective yoke plate and the other recess being arranged on an extension piece attached to the yoke plate by means of detachable fastening means .
