Definitions

  • the invention relates to an installation arrangement for installation work in an elevator hoistway during construction of a building, the installation arrangement comprising at least one installation deck configured to move along an elevator hoistway and configured for carrying out installation operation in the hoistway of the elevator.
  • Such kinds of installation arrangements as e.g. platforms or construction elevators are needed in the construction stage of a building to transport constructors and/or equipment to desired places of the building site. Furthermore, mechanics and constructors working in an elevator hoistway as well as on floors should be able to use an elevator to move between floors.
  • Known prior art solutions use movable installation platforms, which are suspended and moved by hoisting ropes. The hoisting ropes run via a traction sheave of a hoisting machine disposed in a separate machine base structure (sometimes called cathead) above the installation platform. The machine base structure is erected stepwise as the construction work proceeds, such that hoisting height of the installation platform increases in steps.
  • the object of the present invention is to provide a new kind of installation arrangement for installing an elevator during construction of a building, which overcomes the above mentioned disadvantages at least partly.
  • the invention also refers to a construction time elevator comprising such an installation arrangement.
  • the installation arrangement comprises an installation deck, which is used for the installation operation. Builders and mechanics can work from the installation deck. It can also be used for transporting construction material and for example elevator components up to the building.
  • the installation arrangement further comprises at least one mover forming a part of a linear motor, which mover has motor windings and is connected to the installation deck.
  • the mover is configured to co-act with at least one stator beam, forming the other part of the linear motor, located vertically in the elevator hoistway.
  • the movable body thus allows movement of the installation deck within the movement range defined by the stator beam.
  • a horizontally-located stator beam may be provided to establish an installation deck movable in horizontal direction to use used for installation and construction of the building.
  • the installation arrangement comprises a motion and safety control unit connected to the installation deck comprising drive and safety components for the operation of the linear motor.
  • the motion and safety control unit comprises an elevator drive unit, e.g. an inverter, and an electronic or mechanical overspeed governor, so that the installation arrangement and the at least one vertical stator beam in the elevator hoistway form a construction time elevator which is ready to use and meets all the official safety regulations.
  • the arrangement is on the other hand easy to install and to use.
  • Electronic overspeed governor means an overspeed governor comprising an electronic supervision unit, such as for supervising movement of the installation deck.
  • the installation arrangement comprises a power source, in particular a battery, for supplying power to the motor windings.
  • a power source may comprises a high-power battery, such as a lithium-ion battery, for feeding electrical power to the motor windings.
  • the battery is preferably charged during idle times via a battery charger, such as a wireless charger or a one-phase AC supply cable connected to a battery charger.
  • a battery charger such as a wireless charger or a one-phase AC supply cable connected to a battery charger.
  • This has the advantage that no three-phase feeder cables are needed for operating the mover / installation deck combination, but a temporary power connection may be adequate in the building site.
  • the whole construction time elevator does not need high voltage feeder arrangements, such as a vertical feeder bar for AC mains in the shaft.
  • the power source my act as a backup power source in case of any power failure of AC mains.
  • the installation arrangement also comprises mechanical brakes, which are dimensioned to stop and hold the installation deck in elevator hoistway.
  • the brakes are preferably arranged in connection with the mover(s).
  • the brakes are configured to interact with the stator beam and/or with guide rails located in the elevator hoistway.
  • the brakes may comprise friction pads and/or wedges to clamp two side faces of the stator beam.
  • the brakes can also be embodied as locking means, e.g. comprising sprocket wheels or friction roller co-acting with the stator teeth of the stator beams, which would provide a friction-based or form-fit safety arrangement which also could be used as part of an overspeed governor.
  • the sprocket wheel or friction roller could be braked via brake-pads or wedges.
  • Such type of wedges can automatically be drawn back from a locking position at the sprocket wheels/friction rollers in contrast to conventional wedges which are clamped between a guide rail and a gripping device body, in which case the car has to be drawn off the wedges with a lot of effort.
  • a locking means is connected to the installation deck, which locking means is configured to interact with a surrounding building structure or the stator beam and/or guide rails located in the building. With such locking means the installation deck may be locked tightly into its place in the hoistway before starting the installation work.
  • This locking means preferably comprises a mechanical form- or friction-based interlocking of at least one locking element connected to the installation deck and a fixed element mounted in connection with the hoistway, e.g. with the stator beam(s) or guide rails.
  • the locking means may be integrated with the mechanical brakes.
  • the installation deck could be dismantled and a separate construction-time elevator car will be mounted to the same mover(s). This construction-time car will then be used for transferring materials and constructors up to the building. It is also possible to use even two or more mover/platform or car combination in the same hoistway moving along the same stator beam to speed up the building process.
  • the invention simplifies the usage of the installation arrangement and the corresponding construction time elevator and provides following real advantages for building constructors.
  • Even the building infrastructure does not need to be completed.
  • This system can be used clearly earlier than any conventional systems.
  • in case of using a battery as power source even no electric installation has to be completed? in the hoistway to use the construction time elevator.
  • the installation deck preferably comprises a lower deck and an upper safety cover mounted above the lower deck.
  • the purpose of the safety cover is to protect workers working on the lower deck.
  • the safety cover may also function as an upper installation deck which can be used by workers to extend the stator beam(s) upwards by mounting new stator beam segments on top of the already mounted stator beam segments so that the range of the construction time elevator slowly increases in the upwards direction, which extension can be performed in a very safe way.
  • At least two movers are connected side by side to the installation deck and co-acting with two parallel vertical stator beams in the elevator hoistway.
  • these stator beams are placed in a distance so the corresponding movers connected to the installation deck are placed near the edges or ends of the side of the installation deck where the movers are mounted.
  • At least two movers may be mounted above each other on a mounting structure to double up the propulsion force generated in connection with one stator beam.
  • the installation deck may be mounted to a vertical support frame to which the movers are mounted.
  • This support fram offers the option to arrange several movers above each other.
  • this support frame offers the option to mount several installation decks to it, e.g. a lower deck and an upper deck.
  • the motion and safety control unit comprises all drive and safety components for the operation of the linear motor, so that now components have to be located in the shaft or hoistway.
  • all necessary shaft equipment is/are the stator beam(s) and optionally a vertical electric feeder bar in the shaft for the electrification of the mover and of all electric components mounted in connection with the installation deck.
  • the mover comprises also permanent magnets co-acting with the stator beam. Accordingly a flux-switching permanent magnet motor (FSPM) can be used which has a good efficiency and performance.

  • at least some of the permanent magnets in the stator side are designed in the form of schach arrays.
  • the motion and safety control unit comprises the elevator drive unit for energizing the windings of the mover to provide a desired propulsion force and speed of the installation deck along the stator beam.
  • an electronic overspeed governor is used as overspeed governor, as this avoids the necessity of a mechanical interlocking of a first overspeed governor part connected with the installation deck with a second overspeed governor part connected with the hoistway, e.g. with the stator beam, guide rail or feeder bar.
  • the motion and safety control unit comprises at least one motion sensor for sensing absolute position and movement of mover/installation deck. This enables the constructor to perform installation work exactly in a desired height of the hoistway.
  • the sensor signal may also be used as base signal for the motor drive, for safety purposes, e.g. speed control as well as for the indication of hoisting speed and for the electronic overspeed governor.
  • the motion and safety control unit comprises a wireless charger for charging the power source, preferably if the installation deck is in an idle position, e.g. on the ground floor. This always keeps the power source in a sufficient charging state to enable the use of the linear motor during working time. The same holds true if the power source is only used as a backup power source aside of a normal AC mains supply, e.g. via a vertical feeder bar in the hoistway in connection with a tap connected to the installation deck.
  • the motion and safety control unit may be provided with a socket for 1-phase AC supply line.
  • all drive components are enclosed in a control cabinet to provide protection against an electrical shock, this way safe maintenance work may be ensured, there is no need to provide additional isolation protection in shaft.
