Definitions

  • the invention relates to a method for modernizing a drive of a lift installation according to the preamble of independent claim 1.
  • An elevator system aims to transport people and goods within a building between floors.
  • a cabin serves to accommodate the people and goods.
  • a drive drives by means of suspension the cabin, which is thereby moved up and down in a vertically extending shaft.
  • the suspension element connects the cabin to a counterweight. It is guided by a traction sheave.
  • the traction sheave transmits the force required for the process or the holding to the suspension elements.
  • the traction sheave is driven or held by a drive device and / or by a braking device.
  • Another type of drive drives the cabin by means of hydraulic lifting devices.
  • the driving and holding force is acting by a pump unit directly via a piston acting, or indirectly by means of a rope or chain hoist, transmitted to the cabin.
  • Both drive types have specific usage characteristics and are subject to wear.
  • the usage characteristics are, for example, the driving speed or the load for which the elevator installation is designed. Wear occurs, for example, by a longer lasting Use of the elevator system, which leads to signs of wear on components of the elevator installation. If the usage requirements change or the wear becomes too great, the existing drive or at least the entire elevator system must be replaced or replaced.
  • the object of the invention is now to provide a method for modernizing a drive of a lift system, which is optimally applicable to existing buildings, ie a conversion time is to be shortened and construction adjustments should whurst omitted.
  • An elevator installation includes a drive, a carousel and a counterweight.
  • the car and the counterweight are arranged in a vertically extending shaft oppositely arranged up and down movable.
  • the suspension element connects the cabin to the counterweight and the suspension element is carried and driven by the drive by means of at least one traction sheave.
  • the new drive is modular. It consists at least of the traction sheave and of at least one motor required to drive the traction sheave.
  • the motor and the traction sheave are preferably assembled into a drive module.
  • the core function of the drive is perceived by this drive module.
  • the drive module also includes a braking device.
  • the drive module can be supplemented with a deflection module to allow adjustability of the suspension element spacing.
  • the drive module and the deflection module are preferably connected to each other by means of an extension, which allow adjustment of a required support means distance.
  • the suspension element spacing is the distance between a part of the suspension element strand running to the drive and a part of the suspension element strand running away from the drive.
  • the drive module and / or the deflection module is provided with connection parts, which can be used for fastening the drive within the shaft or in the engine room.
  • the modernization of an existing elevator drive takes place by arranging the new drive outside the space occupied by the existing drive.
  • the advantage of this method is that the existing drive is available for a very long time for the operation of the elevator installation. It can be used in particular to transport the new drive as a whole or in modules close to the installation site, preferably a top floor.
  • the new drive can be assembled and / or completed in the vicinity of the installation site as needed, and prepared for final assembly.
  • the elevator system is still available for the elevator users.
  • the existing support means can now be removed, the new drive mounted and the suspension means are in turn installed and the elevator system is already available again for transport tasks or elevator users.
  • the existing, no longer required drive unit does not affect the operation of the modernized elevator system, it can either be left at its installation location or it can be dismantled on occasion and transported, for example, with the modernized elevator system in a suitable for disposal of the material floor.
  • the method for replacing an elevator drive in an elevator installation is optimally applicable in existing buildings. It requires no or only minor structural measures to allow the installation of a new elevator drive in an existing shaft space. A high safety standard is given since existing equipment can be used widely and the transport of heavy loads is eliminated. The process allows economic processes, since the existing system can be used for a long time and thus the downtime significantly reduced and in particular, since no other transport equipment such as a crane or a helicopter must be rented.
  • Fig.1 , and Figure 12 show examples of elevator systems 1 with held on support means 2 car 3, and counterweight 4, which are in a vertically extending shaft 5, opposite, up and down movable.
  • FIG.1 shows an example with a, before the conversion, overhead engine room 8, which is rebuilt by means of direct or 1: 1 suspension.
  • Figure 12 shows an example with a, prior to the conversion, down / side machine room 8 and associated roller assembly 33, which is converted by means of 2: 1 suspension.
  • Suspension means a selected transfer factor.
  • the support means 2 is firmly connected to the 3abine 2, or counterweight 4, in 2: 1 suspension, the support means 2 by means of deflection roller to the car 3, or counterweight 4 is connected.
  • the original space required by the old or existing drive machine 9 is not required in both examples for the new drive 7.
  • the new drive 7 is arranged outside the space required by the old or existing drive 9 space.
  • the old engine 9 can, as shown in the examples, be left in the assembled state and disassembled at a later time, or the existing drive 9 can be disposed of using, for example, the car 3 as a transport container.
  • the former engine room 8 can be used for other tasks.
  • a controller 10 required for the new drive 7 can be arranged in the former machine room 8, or in the access area of a storey door, or at another location, preferably in the vicinity of the drive 7.
  • the modernization can be completed in a very short time.
  • the downtime of the elevator system is low. This is especially economical.
  • the relative position of car 3 and counterweight 4 to each other and with respect to well space boundaries 36, as in the Fig.1 . 11 . 12 and 13 presented essentially unchanged.
  • This allows in particular a reduction of the conversion time, since existing installations can be left and the modernization costs are low. Complex adjustments to the building structure are eliminated.
  • the unchanged relative position of the car 3 and counterweight 4 to each other and with respect to manhole boundaries 36 means that the position of guide rails 34, 35 is not changed substantially, even if optional guide rails 34, 35 are replaced.
  • the new drive 7 is, as in the Fig.2 and 3 shown, modular design.
  • a drive module 11 is provided with a traction sheave 12 for the support means 2 of the car 3 and counterweight 4, with a motor 21 required for driving the traction sheave 12 and in the example shown with a braking device 14 required for braking the traction sheave 12.
  • the drive device 13 and the traction sheave 12 are one Drive module 11, as in Figure 4 exemplified, assembled.
  • the drive module 11 is provided with interfaces 15. These interfaces 15 allow the connection of connection parts 16.
  • These connection parts 16 allow either a mounting of the drive module 11 within the shaft 5, for example, to the shaft ceiling 6 as in the Fig.1 . 7 and 8 seen on the floor of a conventional engine room 8 as in Figure 5 represented or on the bases 17 a previously dismantled old prime mover 9 as in Figure 6 shown or on a support 32 as in Figure 12 seen.
  • the interfaces 15 allow the connection of an extension 18, to which a deflection module 19 is connected, such as in the Fig.1 . 2 and 3 shown.
  • the extension 18 together with the drive module 11 and the deflection module 19 allows adjustment of the support means distance corresponding to the requirements of the elevator installation 1.
  • the deflection module 19 in turn contains interfaces 15 which allow the connection of fasteners as used in the drive module 11.
  • the interface 15 of the drive module 11 and the interface 15 of the deflection module 19 are identical. This allows for easy installation, since when attaching the extension 18 there is no possibility of confusion.
  • the extension 18 and the deflection module 19 are designed such that the overall height of the drive 7 through the assembly of drive module 11, extension 18 and deflection module 19 is not changed.
  • the interfaces 15 are designed functionally. They allow a modular composition of the drive 7 according to the requirements of the building.
  • An additional advantage is that the individual modules and parts can be transported separately to the installation site.
  • the transport units are small and have a low individual weight. For example, they can be transported to the vicinity of the installation site in the building by means of an old elevator installation 9 intended for conversion.
  • this drive 7 is best suited for replacing existing drives 9 by being optimally adaptable to existing buildings, i. it can be arranged both within the shaft 5 as in an existing engine room 8.
  • the support means distance is also easily adjustable. The setting of the support means distance does not affect the overall height of the drive 7.
  • the drive module 11 is optionally provided with a guide roller 20, which ensures a, independent of the support means distance, wrap around the traction sheave 12 by the support means 2.
  • the wrap angle ( ⁇ ) is 90 ° to 180 °.
  • This wrap can be achieved by the arrangement of the guide roller 20th to be changed.
  • a wrap angle ( ⁇ ) in the vicinity of 180 ° is desired.
  • the advantage of this arrangement is that the wrap angle ( ⁇ ) can be defined independently of the carrier mean distance.
  • the drive module 11 can also be used directly without using the guide roller 20. This results depending on the arrangement, a wrap angle ( ⁇ ) of 90 ° or 180 °, as in the schematic diagrams 4a, 4b and 4c shown.
  • the support means 2 has, as in the 4d to 4f 2 has a substantially circular cross-section or has a substantially flat cross-section, the surface serving to transmit the driving force being smooth, longitudinal, serrated, studded, perforated or of any other structure, or the support means 2 has any cross-section ,
  • the traction sheave is designed such that the transmission of the driving force from the traction sheave on the support means 2 is functionally enabled
  • the drive 7 is not limited to a specific support means 2. It is suitable for a variety of load-bearing profile shapes. It is advantageous if support means 2 are used, which are suitable for small deflection radii. As a result, the drive 7 can be made particularly small.
  • the drive module 11 is provided with interfaces 15, which allows the attachment of several connection parts 16.
  • the advantage of this embodiment results from the universal applicability of the drive module 11.
  • the interfaces 15 allow the attachment of the connection parts 16 required for a specific elevator installation 1.
  • the interfaces 15 are, as in the Figure 3 . 4 . 9 and 10 seen, for example, slots or hole arrangements or jaws for receiving connection means.
  • the connection parts 16 are optionally extension 18, deflection module 19, suspension or support modules 25, 26, or suspension means end connections 27 or further aids.
  • the design of the drive module 11 with functional interfaces 15 allows the use of the drive module 11 for many types of elevators, and this allows a rational and cost-effective production of the product.
  • a first advantageous connection part 16 is an extension 18, which is arranged with an end region on the interface 15 of the drive module 11, and at the other end region of a deflection module 19 is attached.
  • the deflection module 19 has the drive module identical interface 15.
  • the advantage of the extension 18 is that an adjustment of the support means distance is possible.
  • universal drive and deflection modules can be used, which in turn allows a rational production of the drive.
  • the deflection module 19 and the drive module 11 have the same interfaces 15. This is particularly advantageous because it increases the design options. For example, instead of the arrangement, drive module 11 and deflection module 19, two drive modules 11 can be used. As a result, the performance of the drive system 7 can be significantly increased.
  • the interface 15 of the drive module 11 and the deflection module 19 for extension 18 allows a fine adjustability of the Tragstoffdistanz.
  • This advantageous embodiment allows adjustment to the actually existing carrier distance. Thus, there is no skew, whereby a wear of the support means 2 is reduced.
  • connection part 16 is a suspension module 25 which is arranged on the interface 15 of the drive module 11 and / or the deflection module 19, which allows the suspension of the drive to a shaft ceiling 6, or another connection part 16 is a support module 26, which the interface 15 of the drive module 11 and / or the Umlenkmoduls 19 is arranged, which allows the attachment of the drive 7 in a machine room 8 or on a shaft wall.
  • the support module 26 is, for example, as in Figure 12 shown used to arrange the new drive 7 in place of existing pulleys 33.
  • the new drive 7 is mounted on carrier 32 here.
  • the carriers 32 are usually as in the Figure 12 visible, supported in wall niches or they are connected by means of consoles to the shaft wall or a shoring.
  • the new drive 7 can also be attached to counterweight guide rails 34 and / or cabin guide rails 35, provided that they are dimensioned accordingly.
  • the hanging or support modules 25,26 are advantageously provided with noise or vibration damping materials.
  • the advantage of this embodiment is the fact that an appropriate building type attachment can be selected.
  • the suspension module 25 advantageously uses threaded or support rods, which allow adjustment of the installation height. The new drive machine 7 can thus be easily leveled.
  • the hanging module 25 uses, for example, existing openings in the shaft ceiling 6, or in the bottom of the overhead engine room 8 to hang the drive 7 to the shaft ceiling 6, wherein the counterplates required in the engine room 8 are made long and narrow, and between the existing machine bases 17 are arranged.
  • the counter plates may have other shapes, as they are useful for the arrangement. For example, they can be round if required.
  • any machine base 17, which for fastening an old Drive 9 were used, can be left. This reduces the conversion time and the associated costs.
  • individual interfaces 15 and associated connection parts 16 are designed as integrated components of the drive 7.
  • a support module 26 may be embodied as a fixed component of the drive or deflection module.
  • the drive module 11 and / or the deflection module 19 is advantageously provided with suspension means end connections 27.
  • the advantage here is that the interfaces are reduced to the building, since all supporting forces from the car 3 and counterweight 4 are performed on the drive unit 7 and are introduced via the suspension points of the drive 7 in the building.
  • the arrangement of the suspensions allows the use of a 2: 1 umhlindfitten arrangement in elevator systems 1, which were hung in the old version directly, or 1: 1.
  • This arrangement is made possible by a particularly advantageous design of Tragstoffendriven. This is advantageous because small drives can be used, whereby the space requirement remains low.
  • the drive module 11 and / or the deflection module 19 is provided with an interface 15 for fastening an auxiliary hoist 28.
  • the auxiliary hoist 28 is used for installation-related process of elevator material and / or installation personnel.
  • inventive drive 7 is transported by means of the old elevator installation 1 in the vicinity of the installation site, preferably in a top floor 30 and completed there with the necessary connection parts 16.
  • the old cab 3 is now set and secured in the vicinity of the top stop 30 and the old support members are dismantled.
  • the roof of the cabin 3 can be used as Häplatform.
  • the inventive drive 7 is preferably lifted using the existing cable bushings and a mounted in the machine room 8 drawbar 29 to the shaft ceiling 6 and fixed by means of suspension module 25. Now the new suspension 2 can be retracted.
  • the elevator installation can move into an assembly operation and the cabin can be moved; depending on the conversion agreement, the remaining shaft equipment can be replaced.
  • the canopy is advantageously used as Montageplatform.
  • any components of the old machine room equipment, such as drive machine, control boxes, etc. are transported to a suitable floor.
  • a suitable floor is for example a floor which can be easily reached for transport purposes.
  • An auxiliary hoist 28 is not required in this example and the elevator system 1 is again available to the customer after a short conversion time.
  • the elevator 10 associated with the control and / or drive control is advantageously arranged in the engine room 8.
  • it can also be arranged wholly or partly in the shaft 5 or in an easily accessible location, preferably in the vicinity of the drive.
  • a machine room 8 is often available.
  • the machine room 8 can at least partly not be used elsewhere.
  • the old drive 9 is located on a shaft superstructure which ensures a sufficient safety distance from the canopy to the shaft head or the components installed therein. He is thus within the engine room 8 in an elevated position. Accordingly, the machine room 8 can not be used in its full height, especially in this subarea. This portion of the engine room 8 is particularly suitable for an arrangement of the new controller 10 and / or drive control.
  • the electrical connection to the drive 7 is usually possible simply by existing openings in the shaft ceiling 6.
  • the best arrangement of the controller 10 and / or the drive control can be selected. It is particularly advantageous that a, for the purposes of the elevator installation 1 no longer required existing engine room 8 or at most parts thereof is free for other use. A corresponding part of the machine room 8 can be separated by an intermediate wall.
  • the methods shown are examples. Combinations are possible. For example, only the drive can be renewed on a case-by-case basis or, for example, the entire system including the cab, counterweight, etc. is renewed.
