Definitions

  • the invention relates to a Tragstoffenditati, as well as an elevator system with such Tragstoffenditati and a method for attachment of support means to a Tragstoffenditati.
  • Areas of application for such a Tragstoffenditati are, for example, support and drive systems for cabins of passenger and goods lifts.
  • Elevator systems usually have an elevator car and a counterweight which are movable in an elevator shaft or along free-standing guide devices.
  • the elevator installation has a drive unit with at least one drive element in the form of a traction sheave, wherein the traction sheave transmits the required drive forces to the elevator car and the counterweight via at least one flexible support means.
  • Required additional deflections of the support means are usually realized by deflecting elements in the form of pulleys.
  • the suspension elements can either be attached directly to the elevator car and the counterweight, or in the elevator shaft or also to the guide devices.
  • the suspension elements are fastened to the cabin, the counterweight, the elevator shaft or the guide devices via suspension end connections.
  • the Tragstoffend be suspended for example via a threaded rod on a holding element.
  • the present invention has as its object to provide a Tragstoffendinformation which holds the support means with increased security in the Tragstoffenditati.
  • the Tragstoffendtagen should also allow a simple and secure looping of the support means in the housing of Tragstoffenditati.
  • the suspension element end connection according to the invention for an elevator installation for fastening a suspension element to a support structure has a housing with two opposite side walls.
  • a first element for wrapping around the suspension element is at least partially looped around by a suspension element loop, and a second element for wrapping around the suspension element is received in this suspension element loop.
  • the first element is non-displaceably connected to the housing, the second element is rotatably arranged.
  • the second element has an eccentrically arranged projection.
  • This arrangement of the support means in the TragstoffendENS has the advantage that the support means in a simple manner in the Tragstoffendtagen can be run. Because only one of the elements to be wrapped is firmly connected to the housing, the support means must not be cumbersome around two elements around. It is sufficient to form a loop with the support means, and to put this loop around the fixedly connected to the housing first element. The second, free element is placed in the loop through openings in the sidewalls of the housing. By a rotation of the second element on the one hand, the support means between the first element and the projection of the second element is clamped, and on the other hand, the second element is locked in the housing, because the projection in the rotated state is no longer feasible through the openings. As a result, the suspension element can be securely and simply fastened in the suspension element end connection without the need for additional securing devices.
  • This has the advantage that further items can be attached to the suspension element end piece before assembly (prefabricated), which have a cross section that would no longer allow the looping in of the suspension element end piece.
  • the tension members are usually not visible and therefore not visually inspect for defects, because they consist for example of several parallel strands, which are surrounded by a plastic sheath. Therefore, for monitoring the suspension element for defects, for example, connecting pieces are fastened to the suspension element such that individual strands of the support means can be contacted electrically. Since the attachment of such monitoring fittings may require special tools, it is advantageous if this can not be done in the assembly of the elevator, but in advance in the factory. As a result, the time required for mounting the suspension element in the elevator is additionally reduced.
  • Another advantage of the inventive arrangement of the support means in the TragstoffendENS is the increased security.
  • This arrangement has both the advantages of a wedge-lock type end connection as well as the advantages of opposing wrap around two elements.
  • the support means On the first, firmly connected to the housing element, the support means is in two opposing layers. Due to the opposition, there are high frictional forces between the superimposed layers of the support means, which are reinforced by the high contact pressure caused by the gravity of the car or the counterweight.
  • the second, rotatable element with the projection has a self-reinforcing effect on a clamping of the suspension element: If the tensile force of the support means larger, then the projection of the second element is stronger pressed against the first element.
  • This self-reinforcing effect additionally serves in the present invention as a second security to the holding force of the opposing layers of the support means on the first, firmly connected to the housing element.
  • the method according to the invention for fastening a suspension element to a suspension element end connection comprises the following steps: arranging the suspension element in the suspension element end connection such that a suspension loop at least partially surrounds the first element and the second element is arranged in the suspension loop; Rotating the second element, so that the support means is clamped between the projection of the second element and the first element.
  • a Tragstoffendthetic with a housing having two side walls, a housing connected to the first element and a second element is used.
  • a suspension element end connection according to the invention is preferably used. This allows a simple and quick installation and ensures an improvement in safety.
  • the support means tail is not guided into or through the housing during attachment of the support means to the support means end connection.
  • the inventive Tragstoffendinformation and the inventive method for attachment of support means to a Tragstoffenditati can also be used in other areas, such as for fastening of load straps.
  • FIG. 1 an elevator installation 20 is shown by way of example.
  • a shaft 22 In a shaft 22 are a car 24 and a counterweight 25, which are interconnected via one or more support means 2.
  • An attached to the shaft wall 23 drive 28 transmits via the drive pulley 27 driving forces on the support means 2 to move the car 24 and the counterweight 25.
  • the Supporting means 2 is attached via a Tragstoffenditati 1.
  • the support means take over carrying and driving function, or even only one of the two functions.
  • the drive may be, for example, on the cab, up or down the shaft, or in a separate engine room.
  • the anchoring of the Tragstoffendtell 1 takes place in the illustrated embodiment via a threaded rod 29 and a retaining element 21 on the shaft wall 23.
  • the Tragstoffendtagen 1 can also be anchored elsewhere, for example by a direct connection, such as a weld, with a fixed structure of the elevator system .
  • the suspension element end connection 1 can also be anchored to a guide rail or to a support structure arranged in the shaft 22 or to an additional auxiliary construction (not shown).
  • the suspension element end connection according to the invention can be anchored to the car and / or to the counterweight (not shown).

While certain frictional properties are important for the traction side 18, for example, longevity or rigidity may be the focus of the rear side 19.
  • the traction side 18 of the support means 2 is designed with longitudinal ribs in order to be able to optimally guide the belt on the deflection and drive rollers and to optimize the friction properties.
  • FIGS. 3a and 4a is ever an exemplary embodiment of a support means loop 12 is shown.
  • the support means 2 is folded close to one end 13 of the support means 2, so that a loop 12 with an eye 14 and a portion on which the support means 2 runs in opposite directions and substantially parallel arises.
  • the eye 14 of the support means loop 12 has a width. This width depends on the properties of the suspension element 2. In the case of a belt with a strand thickness of 1.75 mm, the width of the eye 14 is approximately 25 mm, for example. If support means with other properties, for example with thinner or thicker strands, are used, it should be ensured that the width of the eye 14 can have a different size. Consequently, it may be necessary, the dimensions of the housing 3 of the TragstoffendENS 1 vote on the properties of the support means 2, which is obvious to the expert.
  • FIGS. 2 to 4c each exemplary embodiments of a Tragstoffendtagen 1 are shown with a support means 2.

These open sides facilitate the arrangement of the support means loop 12 in the TragstoffendENS 1, as you can reach into the housing 3 with your hands at several points.
  • the webs 11, 6 may be wider, so that the housing 3 - except for an outlet opening for the support means 2 - has closed walls.
  • the first element 4 and the webs 6 and 11 are arranged in the housing 3 such that minimum distances between the first element 4 and the webs 6 and 11 are greater than a width of an eye 14 of Carrier loop 12. This allows for looping the support means loop 12 in the TragstoffendMIS 1 with the eye 14 ahead and around the first element 4 around.
  • the upper web 11 has a bore 7. This serves to attach the Tragstoffenditati 1 to other suspension structures (not shown). Typically, a threaded rod is threaded into the bore 7, which is then anchored in a mounting structure. Another function of the upper web 11 is to stabilize the housing 3.
  • the at least one lower web 6 reinforces the housing 3.
  • An outlet opening between the side walls 9, 10 and adjacent to the lower web 6 serves to guide the suspension element 2 into the housing 3 and out of the housing 3.
  • the outlet opening is preferably used to introduce the support means 2 in the housing 3.

  • the first element 4 can be designed as a hollow cylinder, or as a solid cylinder.
  • the surface of the first element 4 may be smooth, or it may have a rough structure to increase the static friction. In this case, profile-like patterns can be used, such as transverse ribs or grooves.
  • a second element 5 for wrapping around the suspension element 2 also extends essentially between the side walls 9, 10 of the housing 3.
  • the second element 5 is not fixedly connected to the housing, but rotatably mounted therein.
  • the second element 5 is preferably designed as a cylinder with an eccentric projection. As in the FIGS. 3a and 4a shown, this cylinder may have a circular base surface 15. Alternatively, the base 15 may for example also be teardrop-shaped, oval, wedge-shaped, or egg-shaped.

Because the projection 8 of the second element 5 has the result that this projection is not circular, the second element 5 can only be guided through the openings 16 in a specific introduction position. If the second element 5 is completely inserted into the housing 3, ie if the side portions 17 are each in an opening, then the second element 5 is rotatable about its axis of rotation, because the eccentric projection 8 is now located between the side walls 9, 10 and will not be stopped by them. In this use state, the second element 5 is thus rotatable from the insertion position into a locking position. In this case, a position of the eccentric projection 8 is variable. In the locking position, the projection 8 is arranged so that the support means 2 is clamped between the projection 8 and the first element 4.
  • the suspension element 2 can be arranged in the suspension element end connection 1 such that the first element 4 can be wrapped at least partially by a suspension element loop 12 formed by the suspension element 2, and that the second element 5 can be received in this suspension element loop 12.

  • An axis indicates how the second element 5 and the support means 2 in the housing 3 can be arranged in a use state.
  • a side wall 9, 10 can only be connected to the rest of the housing 3 when the support means loop 12 has already been arranged around the first element 4. In this case, the support means loop 12 does not have to be guided through the outlet opening 8, but can be pushed laterally onto the first element 4.
  • a fastening element (not shown), for example, a cable tie, are attached to the oppositely parallel sections of the support means 2.
  • This fastener may facilitate attachment of the support means 2 in the support means end connection 1, but this method may be practiced without such a fastener.
