Definitions

  • the invention relates to a traction sheave elevator with an elevator car, which can be moved along guide rails, with a counterweight also guided on rails, with in Cross section round suspension elements on which the elevator car and the counterweight is attached without a pulley in a backpack design are, and with at least one engine, one Traction sheave for the suspension means and a brake formed Drive that is in the upper area of the elevator shaft between the Shaft wall and the space that the elevator car in its top position needed, and / or in a vertical extension this area is arranged, the axis of the Traction sheave approximately horizontally and at the same time parallel to the neighboring one Shaft wall and / or to the adjacent cabin wall is oriented.
  • Such a traction sheave elevator is from the Japanese utility model publication JP 4-50 297 known.
  • the advantage this arrangement is that a separate machine room for the drive of this elevator is not required.
  • the Backpack construction advantageous because it is inexpensive as it with relatively few parts and even without deflection disks.
  • an arrangement of the traction sheave on a horizontal lying parallel to the adjacent shaft wall Axle a convenient loop and guide for the suspension elements.
  • WO 99/43589 is also used for an elevator of a different type Deflection rollers under the elevator car have been a relatively long time Drive engine known in the upper area of the shaft, however it is not a backpack-style elevator and above all, special ropes are used as suspension elements, namely flat ropes or straps are required to ensure adequate Traction is transmitted and still the traction sheave can be carried out with a relatively small diameter.
  • the suspension means Steel wire ropes with a nominal diameter of about 8 mm or are less. This allows a correspondingly small diameter the traction sheave and still use more common Wire ropes as a suspension element, so that the usual known Calculation methods can be applied. This also bears contribute to an overall inexpensive, space-saving traction sheave elevator ready to provide.
  • the diameter of the traction sheave can be about 36 cm or 32 cm or less.
  • the torque requirement is correspondingly low on the one hand and the space requirement on the other.
  • the axial length of the drive can be at least twice as large in particular about 2 1/2 times to 3 times or more than the diameter of the traction sheave. Accordingly slim the entire drive fails and is correspondingly low Space required between the cabin and the shaft wall or if necessary in a vertical continuation range of this distance between Cabin and shaft wall.
  • the traction sheave can be directly on the output of the motor arranged and the drive is designed in particular gearless his. Because the torque requirement of the traction sheave by the aforementioned Measures can be kept low, a transmission can be saved.
  • the axial length of the drive pulley can be chosen so that they have space for at least five, in particular six suspension elements or has hoisting ropes axially next to each other. This allows for small Traction sheave diameter the transmission correspondingly higher Load capacities, so that despite the small suspension means in diameter the elevator car enables a satisfactory payload.
  • one clear distance between the carrier provided and the drive can be the one located between the carriers Bridge the gap or space in the assembled position.
  • the straps can also be attached to consoles be anchored to the shaft walls.
  • the two spaced carriers can thus by the respective drive attached to each other to form a structural unit be connected before or after the assembly is formed.
  • Those used to hold the drive in the elevator shaft Carriers can be roughly horizontal and parallel to the drive immediately adjacent shaft wall mounted in the elevator shaft be and attachment points or feet of the drive can be on the top or on the bottom or - with profiled Beams - essentially horizontal in cross-section oriented flanges or legs of these beams in Use position be fixed.
  • an attachment on the top of the straps or also on the top of Flanges or thighs provide great security because the Force application based on pressure.
  • a further embodiment of the invention can consist in that the feet or attachment points of the drive with at least a plate or several cross struts are connected in turn in particular detachable on the carriers, consoles or the like are attached. This will result in greater stiffening this construction unit from the drive and its Attachment achieved.
  • a simplification of assembly and possible disassembly can be achieved if at least one of the two carriers Can be moved parallel to itself and therefore the distance between the two carriers can be enlarged such that the Drive for assembly or disassembly between the carriers is movable through.
  • a drive mounted on the carrier can then either be pulled up over the straps from below or be drained between them. Conversely, it can also a drive hanging from under the brackets from above drained between the initially moved carriers and then assembled or when disassembling between the beams be pulled up.
  • the diameter of the traction sheave can already be used for the above explained dimensional ratios equal to or less than theirs axial dimension and in particular about half of the axial length of the traction sheave. This way offers the traction sheave has enough space for several side by side Suspension means, especially those in their training and Flexibility of particularly cheap round wire ropes with relative small diameter or cross section.
  • Another convenient way to attach the drive can be that the drive with its attachment points directly or through one or more consoles on the shaft wall adjacent to the drive, in particular by means of anchors engaging approximately horizontally in this shaft wall is attached. This allows running through the shaft Carriers are avoided.
  • the drive on or under one Carrier is attached and an additional support on the Shaft wall and / or on at least one or two guide rails is provided to prevent tipping.
  • To this Way can also be the attachment or suspension of the drive inside the shaft and preferably in the space between space-saving yet effective between the cabin and the shaft wall shape.
  • the drive can be used directly or indirectly attached to the shaft wall (s), what towards the solution of the Japanese utility model publication 4-50997 has the advantage that the guide rails for the elevator car or the counterweights are not additionally loaded become. But it is also possible that the drive on one at the upper ends of the elevator car guide rails and / or the counterweight, in particular by means of carriers and / or a plate is arranged, if for example carrier, Consoles or wall fastenings inside the shaft should be avoided.
  • the traction sheave is approximately in the Middle between the guide rails or their extensions is arranged. This allows a largely symmetrical rope arrangement with correspondingly uniform force distribution. It can also be avoided that the traction sheave elevator and especially those from the engine, brake and traction sheave existing drive unit possibly in niches or openings a boundary wall must intervene, that is, such Niches or openings or other weakening of the shaft wall can be avoided.
  • a traction sheave elevator designated as a whole or also abbreviated to "elevator 1” has an elevator car 2 which along for the sake of simplicity in Fig. 1, in Fig. 2, however, indicated guide rails 3 in an elevator shaft 4 can be moved up and down. It recognizes one also in Fig. 1 a counterweight 5, which like the elevator car 2 is guided in a known manner on rails and to the Elevator car 2 performs an opposite movement.
  • the elevator car 2 and the counterweight 5 hang on suspension elements 6, preferably wire ropes, which are round in cross section, and are free of deflection pulleys and in a backpack design.
  • suspension elements 6 preferably wire ropes, which are round in cross section, and are free of deflection pulleys and in a backpack design.
  • an overall designated 7 drive is provided, which is formed from a motor 8, a traction sheave 9 for the suspension means 6 and a brake 10 and especially in FIGS. 3 to 6 also with regard to various fastening options within the Elevator shaft 4 is shown.
  • this drive 7 is located in the upper area the elevator shaft 4 between the shaft wall 4a and the room, which the elevator car 2 needs in its uppermost position or in a vertical extension of this area.
  • This drive 7 in its lateral expansion to the clear distance between the shaft wall 4a and this immediately adjacent cabin wall 2a limited and of course compared to these walls can also keep a safe distance. So can a relatively low shaft head above the top position of the elevator car are sufficient, the elevator car 2 in Fig. 1 has not yet reached its top position.
  • the central axis of the traction sheave 9 and thus also of the motor 8 is roughly horizontal and parallel to the neighboring one Shaft wall and also to the adjacent cabin wall 2a oriented. So that the drive 7 fits into this space, 2 to 6 it is relatively slim and its axial length is greater than its diameter. Furthermore are the motor 8, the traction sheave 9 and also in the exemplary embodiment the brake 10 coaxial to one another or one behind the other arranged. For example, Fig. 3 illustrates that the axial length of the drive 7 larger than the largest diameter this drive is 7.
  • the suspension means suitably designed as steel wire ropes 6 can have a nominal diameter of about 8 mm or less have, so that there is also a relatively small diameter Traction sheave 9 of, for example, about 36 cm or 32 cm or more less realizes what the overall lean training of the entire drive 7 benefits.
  • the axial length of the drive 7 is more in the exemplary embodiment than twice as large, especially about two and a half times to about three times or even several times larger than the one already mentioned, relatively small diameter of the traction sheave 9. This leads to an elongated slim shape of the drive 7 with accordingly small outer diameter that works well in this way the clear space between the shaft wall 4a and the adjacent adjacent cabin wall 2a fits and a relative small dimension of this distance or space allowed.
  • FIGS. 2 to 6 also show that the traction sheave 9 directly on the output of the motor 8 is arranged, the entire drive 7 is gearless overall can be trained. So it's a simple, relatively light and therefore less prone to failure Drive 7.
  • the axial length of the traction sheave 9 is in the embodiment chosen so that they have space for several suspension elements or hoisting ropes 6 has axially side by side. For example, it can be five or six or possibly more such suspension means 6 next to each other record, so that correspondingly large loads be made possible. But here is the diameter of the traction sheave 9 only about the same or even smaller than their axial Dimension and can be, for example, about half the axial Length of the traction sheave 9. This is useful because in sufficient space in the axial direction to accommodate the drive 7 and its traction sheave 9 is present during this space is limited in the transverse direction in that the distance between the cabin 2 and the shaft wall 4a as small as possible should be.
  • FIGS. 3 to 6 there are different options shown how the drive 7 directly or indirectly on the or the shaft walls, be they those transverse to the shaft wall 4a extending shaft walls 8a or also on the shaft wall 4a itself can be attached:
  • 3 to 5 can be used to fasten the drive 7 in the elevator shaft 4 two parallel and at least partially a clear distance between the carrier 11 different cross sections can be provided.
  • the drive 7 bridges the one located between these carriers 11 Distance or space in the mounted position and thereby contributes to stiffen this arrangement.
  • the ends of the beams come to rest on the shaft walls 4b or intervene in these shaft walls 4b in order to prevent them the forces absorbed are preferably introduced into these shaft walls 4b.
  • 3 to 5 illustrate that the two are spaced apart Carrier 11, be it U-profiles according to FIG. 3 or 4 and 5, or other profiles, by the drive 7 each attached to them to one another Construction unit can be connected before assembly or formed only after assembly in the shaft 4 becomes.
  • Fig. 3 shows an arrangement in which the for holding the Drive 7 serving carrier 11 approximately horizontally and parallel to the shaft wall 4a directly adjacent to the drive 7 in the elevator shaft 4 can be mounted, the attachment points or feet 13 of the drive 7 on the top this carrier 11 attack, so that the statics to a pressure load leads at this point. In this case they run Beam 11 at a distance below the shaft cover 12.
  • Fig. 5 it is also indicated that the feet or Fastening points 13 of the drive 7 connected to a plate 14 can be, in turn, in particular releasably to the Carriers 11 or attached to a console or the like is. This is useful if the distance between the Carrier 11 too large for the width of the attachment point 13 the drive 7. In addition, such an additional plate 14 increase the rigidity and stability of the entire arrangement and the two carriers 11 even better with each other connect.
  • Fig. 6 shows an arrangement in which the drive 7 with its attachment points 13 via a console 16 on the Drive adjacent shaft wall 4a is attached.
  • the shaft wall 4a in this area a recess 17, so that the console 16 partly in this recess 17 with vertical Screws 18, partly on the inside of the shaft wall 4a horizontal screws 19 or other fasteners can be anchored.
  • the recess 17 thus enables one very stable attachment of the console 16 and thus also the drive 7 to be realized on the shaft wall.
  • the drive 7 is accessible from the outside of the shaft 4 because of the recess 17 is continuous. If necessary, it is also sufficient a niche as a recess 17.
  • the drive 7 could also be fixed on or under only one support 11 in such a way as shown in the figures by means of two carriers and is described in addition, and there could be additional support on the shaft wall 4a and / or 4b and / or at least one or both guide rails 3 for securing be provided against tipping.
  • the drive 7 could also be shown in FIG Way on one at the upper ends of the guide rails 3 of the elevator car 2 and / or the counterweight 5 for Example can be arranged by means of carriers and / or a plate.
  • This also allows the use of relative heavily dimensioned suspension elements or ropes 6, even if the Diameter of the traction sheave 9 is small and, as already mentioned, Is 32 cm or even less. So this contributes a space-saving arrangement that accommodates the Drive 7 within the shaft 4 allows.
  • the traction sheave elevator 1 with an elevator car 2 running along of guide rails 3 is movable, with one also Counterweight 5 guided on rails and with a cross-section round suspension elements 6 or hoisting ropes is in backpack design executed, that is, the elevator car 2 and the counterweight 5 hang on the suspension elements, which in turn are attached to a traction sheave 9 one formed from motor 8, traction sheave 9 and brake 10 Drive 7 is arranged.
  • This drive 7 is in upper area of the elevator shaft 4 between the immediate adjacent shaft wall 4a and the cabin 2 respectively between the shaft wall 4a and the space that the elevator car 2 needed in its uppermost position or in a vertical Extension of this area arranged.
  • the axis of the traction sheave 9 runs approximately horizontally and simultaneously in parallel to the adjacent shaft wall 4a and to the adjacent cabin wall 2a.
  • the axial length of the drive 7 is greater than its diameter and the motor 8 and the traction sheave 9 are arranged coaxially to each other, so that an angular gear between motor 8 and traction sheave 9 can be avoided.
