Definitions

  • the invention relates to a sliding guide shoe for a lift for passenger or goods transport according to the preamble of claim 1. Furthermore, the invention relates to a method for maintenance or revision of an elevator system with such Gleit Operationssepticn.
  • Sliding guide shoes are often used to guide elevator cars. Elevator systems in buildings have a generally vertical elevator shaft, in which a respective guide rail is arranged on mutually opposite shaft walls. Sliding guide shoes arranged on the elevator car have inlays with sliding surfaces which slide with little play along a guide rail. Sliding guide shoes in which the inserts are configured as profiles of U-shaped cross-section are known and commonly used. In contrast to roller guide shoes, the sliding guide shoe basically has no moving parts. Since the deposits wear off over time, used or old sliding inserts must be replaced.
  • JP 2006-103896 shows a sliding guide shoe with a sliding insert consisting of two side parts and a bottom part, wherein the two side parts and the bottom part in cross-section define a "U" in the inserted state.
  • the slide insert has a profiling on the inside, the tread depth determines whether the worn slide insert needs to be removed, but it is difficult and cumbersome to remove the slide insert, for example because the bottom part is sandwiched between the rubber plates, can hardly be removed separately, so in practice the entire insert together with the sliding insert and rubber plates must be removed from the guide shoe housing.
  • the sliding element is a U-profile made of hardwood, which is surrounded by a U-shaped rubber profile. Hardwood profiles of this type are difficult to produce and expensive, and they are no longer sufficient in terms of sliding properties.
  • the hardwood profile is not supported by the rubber profile but is secured at the top and bottom only by plates bolted to the guide shoe housing.
  • the two-part insert has a sliding element and a carrier element, wherein the sliding element is releasably connected to the carrier element.
  • the carrier element has sliding surfaces on which the guide rail contact with a small amount of play.
  • the support member may have by appropriate choice of materials, structural design or shaping damping properties, whereby a low-vibration ride of the cabin can be ensured.
  • the carrier element itself has at least in the normal case no sliding function.
  • the sliding element is connected to the support member or connectable that it can be removed laterally from the Gleitmentsschuh in the longitudinal direction or inserted into this, the sliding element can be exchanged and replaced as wear part even after the first commissioning of the elevator system and without elaborate arrangements , In particular, it is possible to remove the sliding element while the remaining sliding guide shoe remains on the longitudinally extending guide rail. After removal of the sliding element, the carrier element is still in the inserted position in the guide shoe housing.
  • Carrier element and optionally also the sliding element is designed at least in the inserted state as a cross-sectionally U-shaped profiles, wherein the profile longitudinal direction corresponds to the predetermined longitudinal direction by the guide rail.
  • the U-profile may have two leg walls and a web wall connecting them.
  • the carrier element and / or the sliding element can each be made of flat blanks, wherein the leg walls connect, for example via film hinges to the web wall. To form the profile shape of the blank can be erected from a flat rest position.
  • the sliding surfaces could also be formed by separate components.
  • the outer component of the insert i.
  • the support member may be made of a comparatively elastic plastic such as elastomers based on PU, rubbery materials such as synthetic rubber (e.g., EPDM or NBR) or natural rubber (NR). With the support element noise and vibration can be damped.
  • the sliding element may consist of a comparatively stiff plastic material. Good sliding properties can be achieved if the sliding element is made for example of a material such as PTFE or UHMW-PE with low coefficients of friction.
  • the sliding guide shoe could be designed such that the sliding element can be pushed or pulled out from both sides in the longitudinal direction into the carrier element. Particular advantages, however, arise when the slider is insertable or retractable only from one longitudinal side into the carrier element. With this order can be created a simple, consisting of a few individual sliding guide shoe.
  • the sliding element is supported with respect to the longitudinal direction on one side in each case by a stop, up to which the sliding element is limited in the carrier element can be inserted.
  • the stop may be predetermined by the carrier element, by the guide shoe housing or possibly even by a separate part.
  • the support element has at least one up to a shoulder in the longitudinal direction extending recess for receiving the sliding element.
  • the respective sliding element can be inserted and inserted from the one longitudinal side.
  • the shoulder thereby forms a stop for the sliding element, up to which the sliding element can be pushed into the carrier element.
  • the longitudinally extending, non-continuous recess extends from an open longitudinal side to said shoulder, wherein the shoulder can be created for example by a step in the support element.
  • the support member may be fixed or fixable by means of fastening means positively or non-positively in the guide shoe housing. It would also be conceivable to fix the carrier element using adhesive in the guide shoe housing.
  • the sliding guide shoe has opposite sliding surfaces and a sliding surface extending transversely thereto, which are slidably movable along guide surfaces of the guide rail with preferably little play, it may be advantageous for a sliding element to predetermine the three sliding surfaces, the sliding element preferably being monolithic and monolithic Component is designed.
  • the sliding guide shoe may comprise three sliding elements, each sliding element each forming a sliding surface.
  • This arrangement has on the one hand manufacturing advantages, since the simple-shaped sliding elements can be easily and inexpensively manufactured.
  • the sliding elements made of suitable plastics can be produced for example by extrusion.
  • the sliding elements could also be designed as injection-molded parts made of plastic. Of course, other manufacturing processes would be conceivable.
  • this arrangement leaves one use-dependent replacement of wearing parts too. Any new sliding elements must therefore not be replaced in every maintenance interval.
  • the arrangement with a plurality of sliding elements is further advantageous in that it is particularly suitable for oil-free operation.
  • the sliding guide shoe would comprise only two sliding elements.
  • the individual sliding elements can be designed as a plate-shaped body. Such sliding elements can be produced in a particularly simple and cost-effective manner.
  • three fastening grooves are provided in the carrier element for preferably (in relation to the insertion direction or longitudinal direction) positive reception of a respective sliding element.
  • the fastening groove undercuts and the sliding element to the undercuts have complementary wedge-shaped edge portions, resulting in a dovetail connection between the sliding element and the carrier element.
  • the combination of the three fastening grooves forming the above-mentioned recesses with the sliding elements which can be accommodated therein could also be advantageous for sliding guide shoes having other configurations of the recesses. For example, it is not absolutely necessary for certain applications that sliding elements are supported on a shoulder formed by the carrier element. Such Gleit Eventsschuh could thus have longitudinally extending, continuous recesses (without shoulder).
  • a retaining element can be provided which is fastened or fastened in the region of a longitudinal side on the guide shoe housing.
  • the gliding Ment can thus be included between the support member and the aforementioned stop, whereby the sliding member is securely held in the guide shoe housing.
  • the holding element has a surface on the guide shoe housing resting or alslegbaren mounting wall portion and a spaced from the guide shoe housing retaining wall portion for holding the insert.
  • the retaining wall portion and the mounting wall portion can lie on plane-parallel planes.
  • the holding element may be a bent part made of metal.
  • the holding element can thus be made from a single sheet metal blank and formed by Blechumformmaschinen.
  • the sliding guide shoe may further comprise a preferably separate protective element for protecting the sliding surfaces against contamination from the outside.
  • the protective element can be positioned on an inner side facing the at least one sliding element on the holding element or, for example, attached by gluing. In a fully assembled position, the protective element bears against the sliding element or on the sliding elements and protects itself sealingly therefrom.
  • the protective element is preferably made of a non-metallic material. It may be made of plastic, and preferably of a plastic having elastic properties (e.g., elastomers). For example, PUR, EPDM, NBR or NR are particularly suitable. Furthermore, it is conceivable that the protective element was made of a felt or a non-woven.
  • the sealing effect for protecting the sliding surfaces can be further improved if the protective element is designed flat and has a first surface portion and a subsequent inside, a smaller thickness than the first surface portion having sealing portion which defines a contact surface to the sliding element. Between the surface portion and sealing portion may be a step. An outer edge of one end of the slider may be fitted in the step.
  • the sealing section can form a type of sealing lip inwards which prevents the guide rail acted upon.
  • the protective element and the retaining element can each have an incision at least partially enclosing the guide rail in the operating position.
  • the protective effect can be increased if the incision of the protective element is tapered relative to that of the retaining element.
  • the sliding element used projects beyond the carrier element and / or via the guide shoe housing.
  • the part of the sliding element projecting beyond the carrier element and / or the guide shoe housing can be easily grasped and pulled out.
  • the supernatant should preferably be at least 5 mm and more preferably about 10 mm.
  • the support member may be configured such that it has an upper end which is offset in the inserted position against an adjacent housing surface and / or an edge of the sliding member in the region of the longitudinal side inwardly, whereby a recess or an open towards the longitudinal side cavity between Guide shoe housing and sliding element is created.
