Definitions

  • the present invention relates to a method for erecting at least two elevators in a building which is in its construction phase, the usable lifting heights of these elevators being gradually adapted to an increasing height of the building.
  • the elevators will already be installed in an earlier construction phase as soon as some floors of the building and the necessary elevator shafts with the appropriate Height are created.
  • the usable lifting heights of such elevators can be adapted to the current building height during the construction of the building, so that the elevators grow with the building and can be used for the vertical transport of people or material during the building's construction phase. This means that elevators specially designed for transport tasks during the construction phase - for example those that are attached to the outside of the building - can be wholly or partially saved.
  • Such an elevator installation method is known in which an elevator with an elevator drive machine, an elevator car and a counterweight is installed in a designated elevator shaft as soon as several lower floors of the building and an elevator shaft assigned to the elevator with a corresponding height are built.
  • the elevator car and the counterweight of the elevator are suspended from a drive platform that includes the elevator drive machine, at least one suspension element being guided from the elevator car via at least one drive pulley of the drive machine to the counterweight, and the drive platform being raised to the next higher level by means of a lifting device, if the current building height makes an increase in the usable lifting heights of the elevator systems appear appropriate.
  • the guide rails of the elevator system are successively attached from an assembly platform during the construction phase in the elevator shaft, so that the drive platform for the purpose of adapting the usable lifting height of the elevator along these guide rails can be lifted in the elevator shaft.
  • the drive platform can then be supported on load-bearing elements of the elevator shaft at a desired higher level by means of support beams that can be extended from the drive platform.
  • a lifting platform is used to raise the drive platform and is fixed as far as possible above the drive platform in the elevator shaft before the drive platform is lifted.
  • the lifting platform is equipped with deflection rollers, over which deflection rollers traction means of a hoist mounted on the drive platform are guided. With the help of this hoist, the drive platform is raised together with at least the elevator car in the elevator shaft to a new level adapted to the current building height and supported there. In the final state of the elevator system, the drive platform is used as the machine room floor of the finished elevator system.
  • the WO2011048275 does not contain any indication of a possibility of simplifying or reducing costs in elevator systems in which several elevators are installed in the same building with a usable lifting height that can be adapted to the increasing height of the building.
  • the assembly platform is used to install elevators which are arranged in elevator shafts lying next to one another in a building which is in its construction phase.
  • Each of the elevators comprises a drive platform with a drive machine, which drive machine supports and drives the elevator car.
  • the assembly platforms in the respectively assigned elevator shaft are raised, among other things.
  • the present invention is based on the object of specifying a cost-saving method for erecting elevator systems which comprise several elevators, the usable lifting height of which can be adapted to a building height that increases during the construction phase.
  • the object is achieved in a method for erecting at least two elevators in a building that is in its construction phase, the usable lifting heights of these elevators being gradually adapted to an increasing height of the building, with each of the at least two elevators in an elevator shaft assigned to it of the building is arranged and comprises a drive platform with an elevator drive machine, which elevator drive machine carries and drives an elevator car and a counterweight via a traction sheave and at least one flexible support means, with lifting operations being carried out to adjust the usable lifting heights, in which one of the drive platforms of the at least two elevators in the assigned elevator shaft is raised to a higher level and locked there, and a single lifting platform is used to carry out these lifting operations, which is temporarily above the respective drive platform to be lifted m is fixed in the assigned elevator shaft and forms a support structure via which the lifting force required to raise the drive platform is transmitted to the load-bearing elements of the elevator shaft.
  • the invention is therefore based on the idea of dispensing with the provision of several lifting platforms in an elevator system with several elevators whose usable lifting heights are adjusted by gradually raising the drive platform by moving a single lifting platform to a position above the drive platform to be lifted - or . Above the elevator shaft assigned to this drive platform - is moved. Such a transfer of the lifting platform can take place in each case before or after the lifting platform is raised to a new, higher building level. Since a very stable lifting platform with an adjustable support device and with at least one drive platform hoist is required for lifting a drive platform with elevator car, counterweight and elevator support means, the method according to the invention and the elevator system according to the invention have the advantage that their use can achieve considerable cost savings.
  • the term “elevator shaft” should be understood to mean a room in a building that is in its construction phase, its height increases in accordance with the construction progress, the space being dimensioned and designed in such a way that an elevator car and a counterweight of one elevator each can move up and down along vertical carriageways in the space.
  • Such an elevator shaft can be a single shaft enclosed by shaft walls. However, it can also be part of a coherent room in which the lanes of an elevator car and a counterweight of one of the at least two elevators arranged parallel to one another are arranged, with no shaft wall between the lanes of adjacent elevators, but usually steel girders for fastening of elevator components are available.
  • traction means is to be understood as any elongate and slack component suitable for transmitting tensile forces, for example wire ropes, belts or chains.
  • transfer is to be understood as transporting a lifting platform from an elevator shaft that delivers the lifting platform into an elevator shaft that receives the lifting platform, which transport is usually a lifting in the delivering elevator shaft, a sideways movement between the two elevator shafts and a lowering or lifting in the receiving elevator Includes elevator shaft.
  • a drive platform hoist with drive platform pulling means is installed on the lifting platform to raise the drive platforms, the drive platform pulling means being coupled to the drive platform to be lifted in order to carry out a lifting process.
  • the arrangement of the drive platform lifting mechanism on the single lifting platform has the advantage that only a single drive platform lifting mechanism is required to lift the drive platforms of the at least two elevators.
  • a drive platform hoist with a drive platform pulling device is installed on each of the drive platforms to lift the drive platforms to be lifted drive platform is coupled to the lifting platform positioned above this drive platform.
  • a transfer of the lifting platform between the elevator shafts of the at least two elevators concerned is carried out for alternately lifting the at least two drive platforms, for which purpose the lifting platform is driven on a first lifting platform traction means driven by a first lifting platform hoist and on a second lifting platform driven by a second lifting platform hoist
  • Lifting platform traction means is suspended and the transfer of the lifting platform is effected by coordinated actuation of the two lifting platform lifting mechanisms.
  • This embodiment has the advantage that the lifting platform can be transferred in a particularly simple and cost-effective manner, since cable pull devices that can be used as lifting platform hoists are usually used in elevator assemblies and no additional auxiliary devices - such as horizontal guides - have to be installed for the displacement process.
  • the first lifting platform traction means is guided from a first lifting platform lifting mechanism installed on the lifting platform via a first deflecting body arranged on this approximately above the center of gravity of the lifting platform to a first suspension point, which is above the lifting platform is supported approximately in the cross-sectional center of the elevator shaft releasing the lifting platform on this elevator shaft, and the second lifting platform traction means is guided by the second lifting platform lifting mechanism, which is also installed on the lifting platform, via a second deflecting body arranged on this approximately above the center of gravity of the lifting platform to a second suspension point, which is supported on this elevator shaft above the lifting platform approximately in the cross-sectional center of the elevator shaft receiving the lifting platform.
  • the first lifting platform traction means are fixed to the first suspension point and the second lifting platform traction means are fixed to the second suspension point, or the first lifting platform traction means is via a first lifting platform traction means pulley arranged at the first suspension point and the second lifting platform traction means is attached via a Second suspension point arranged second lifting platform traction means deflection roller returned to the lifting platform and fixed there.
  • the lifting platform in order to transfer the lifting platform from the elevator shaft delivering the lifting platform to the elevator shaft receiving the lifting platform, the lifting platform is lifted from its support points in a first step by pulling the first lifting platform traction means into the first lifting platform lifting mechanism, and in a second step by pulling it in of the second lifting platform traction means in the second lifting platform lifting mechanism, the lifting platform is pivoted around the first suspension point as the pivot center to approximately the cross-sectional center of the elevator shaft receiving the lifting platform, and in a third step the lifting platform is pulled in or out of at least the second lifting platform traction means into the second or out of the second lifting platform hoist brought to the intended vertical position in the elevator shaft receiving the lifting platform.
  • This sequence of the transfer of the lifting platform carried out with the aid of the two lifting platform lifting mechanisms is particularly simple and requires a relatively low expenditure of time.
  • the lifting platform is transferred from the elevator shaft that delivers the lifting platform to the elevator shaft that receives the lifting platform in a first step by pulling it in of the first lifting platform traction means in the first lifting platform lifting mechanism, the lifting platform is raised vertically, wherein or after which the second lifting platform traction means is held taut or tightened by being pulled into the second lifting platform lifting mechanism, and in a second step the lifting platform is opened by letting out the first lifting platform traction mechanism from the first lifting platform lifting mechanism about the second suspension point as a pivot center to approximately the cross-sectional center of the elevator shaft receiving the lifting platform, and in a third step the lifting platform is pivoted to the vertical position provided for it by pulling in or letting out at least the second lifting platform pulling means into the second or from the second lifting platform lifting mechanism brought to the elevator shaft receiving the lifting platform.
  • the lifting platform in order to transfer the lifting platform from the elevator shaft delivering the lifting platform to the elevator shaft receiving the lifting platform, the lifting platform is raised vertically in a first step by pulling the first lifting platform traction means into the first lifting platform hoist. In a second step, the lifting platform is pivoted by pulling the second lifting platform traction means into the second lifting platform lifting mechanism around the first suspension point as the pivoting center to approximately the middle between the mentioned elevator shafts.
  • the lifting platform is pivoted by letting the first lifting platform pulling device out of the first lifting platform lifting gear around the second suspension point as the pivoting center up to approximately the cross-sectional center of the elevator shaft receiving the lifting platform, and in a fourth step the lifting platform is pivoted by pulling in or out of at least the second lifting platform pulling device brought into the second or from the second lifting platform hoist in the vertical direction to its intended vertical position in the elevator shaft receiving the lifting platform.
  • the two Lifting platform hoists operated alternately several times in order to effect an approximately straight lateral displacement of the lifting platform.
  • the suspension points, at which the first and second lifting platform traction means are fixed or deflected are arranged on at least one protective platform, which is temporarily installed vertically displaceable in the area of the upper ends of the at least two elevator shafts that move upwards during the construction phase and is supported.
  • This attachment of the suspension points of the lifting platform traction means in the area of the at least two elevator shafts has the advantage that it can be implemented with little effort because when installing elevators whose usable lifting heights are gradually adapted to an increasing height of the building, such protective platforms in each of the elevator shafts must be present anyway.
  • At least one safety traction means is installed as a fall protection for the lifting platform during the transfer process, which is fixed on the one hand to the lifting platform, from the lifting platform to a safety traction means deflection pulley attached in the area of one of the suspension points for the lifting platform traction means and then back to the lifting platform and guided through a pulling device safety device attached to the lifting platform, which pulling device locking device blocks the safety pulling device and thus a lowering of the lifting platform if a speed at which the safety pulling device moves through the safety catching device exceeds a certain limit.
  • one of the lifting processes in which one of the drive platforms of the at least two elevators is alternately raised to a higher level is carried out before it is carried out a corresponding lifting of the lifting platform within one of the at least two elevator shafts is carried out by at least one of the lifting platform lifting mechanisms with the associated lifting platform traction means guided to a suspension point. This ensures that there is a sufficient distance between the lifting platform and the drive platform to be lifted in order to be able to implement the lifting process in which the drive platform is raised by an intended lifting distance.
  • At least one shock-absorbing element in the form of an elastic roller or an elastic buffer is mounted on the side of the lifting platform. This prevents the lifting platform from colliding with elements of an elevator shaft from leading to damage when the lifting platform is shifted sideways or when it is lifted.
  • a transfer of the lifting platform from one of the at least two elevator shafts to another of the at least two elevator shafts is carried out for alternately lifting the at least two drive platforms, the lifting platform along a substantially horizontally arranged track temporarily installed for this transfer is moved.
  • the drive platform lifting mechanism installed on the lifting platform or a lifting platform lifting mechanism used to lift the lifting platform is used as the drive for moving the lifting platform sideways along the horizontally arranged track, the traction means of the drive platform lifting mechanism or the lifting platform lifting mechanism being arranged in such a way that it extends essentially horizontally from the respective lifting mechanism to a fastening point present in the area of the elevator shaft receiving the lifting platform.
  • the lifting platform lifting gear When using the lifting platform lifting gear, after the lifting platform has been raised, the lifting platform would have to be coupled to a sliding chassis in order to be able to free the lifting platform traction means for lateral displacement.
  • This embodiment has the advantage that the sideways displacement of the lifting platform along a horizontally arranged roadway does not require any additional drive device.
