Definitions

  • the present invention relates to a method for the scaffold-free assembly of an elevator system in an elevator shaft according to the preamble of claim 1.
  • an elevator system To install an elevator system in an elevator shaft, various components of the elevator system must be installed in the elevator shaft. These include, for example, the elevator car, a counterweight, elevator car rails, counterweight rails, at least one suspension cable, a drive, shaft and cabin doors and the electrical installation as well as various other components and small parts. Since an elevator shaft always extends over several floors of a building, it is necessary to transport at least some of the corresponding components into the upper areas of the elevator shaft so that they can be installed there. This is difficult if the elevator system has to be installed in an elevator shaft first.
  • the car of the elevator system to be constructed is first at least partially assembled in the elevator shaft.
  • the assembly can take place on the shaft floor or on a base or on crossbeams that can be installed on the shaft wall.
  • the car is then placed on the shaft floor, the base or the crossbeams.
  • the assembly of the car must be advanced enough that at least one person can stand safely on the car floor or on the car roof.
  • a personnel winch and a safety system are permanently mounted on the at least partially assembled car.
  • the personnel winch can in particular be a winch approved for the transport of persons.
  • the personnel winch is an electric hoist for raising and lowering a load that transports the wire rope connected to the load through the winch.
  • the wire rope can be moved by the personnel winch in particular at a constant speed.
  • an assembly cable is suspended in the elevator shaft, which can in particular be designed as a wire cable.
  • it is either attached directly with a first end to a load-bearing element, or the assembly cable is guided with the first end over at least one deflection pulley attached to a load-bearing element and the first end is then firmly connected to the elevator car.
  • the second end of the assembly cable is connected either directly or over at least one further deflection pulley to a personnel winch that is firmly mounted on the at least partially assembled elevator car and tightened until it is ready for use.
  • the assembly cable can be placed with a suitable section over a traction sheave on the personnel winch and its remaining second end can be laid loosely in the elevator car or loosely guided out of the elevator car and wound up under the elevator car. It is also possible to attach the second end of the assembly rope to a drum connected to the personnel winch and then wind the loose length of the assembly rope onto the drum. While the assembly rope can have any excess length when using a traction sheave, the capacity of a drum is limited, so that the length of the assembly cable must at least approximately match the height of the elevator shaft and the intended suspension.
  • the assembly cable is connected to the passenger winch, once the assembly cable has been connected to the passenger winch, it is possible to move the at least partially assembled elevator car with the passenger winch.
  • the at least partially assembled elevator car can then be moved up and down within the elevator shaft via the passenger winch.
  • the passenger winch is not the actual drive of the elevator system with which the elevator car is moved during regular operation. Since the actual drive still has to be installed in the elevator shaft, the passenger winch is a temporary drive that only serves the purpose of moving the elevator car up and down during assembly work.
  • the assembly rope is also not the supporting rope with which the elevator system will later be permanently operated, but it is only temporarily installed in the elevator shaft, connected to the passenger winch and the elevator car for the duration of the assembly work and then removed from the elevator system again.
  • the additional safety system which is connected to the at least partially assembled car with its integrated safety device against the risk of falling, provides the assembly personnel with sufficient protection against possible malfunctions during the upward and downward travel of the at least partially assembled car when it is moved with the personnel winch. This even applies if the assembly cable of the personnel winch should break. With the at least partially assembled car, the assembly personnel can reach any position within the elevator shaft in order to carry out assembly work at appropriate points in the elevator shaft.
  • the at least partially assembled elevator car can serve as a temporarily suspended passenger transport device as an assembly platform and can move assembly personnel, tools and small and light components of the elevator system up and down in the elevator shaft.
  • At least the assembly cable guided over at least one deflection pulley and the passenger winch are only required for the assembly of the elevator system for as long as the elevator car is required as an assembly platform for assembly work for the installation of components of the elevator system in the elevator shaft.
  • the safety system can also be partially removed from the elevator car if it includes components that do not remain permanently in the elevator car. After these components have been removed from an elevator shaft, they can be reused at another construction site.
  • the invention therefore provides for the use of components of the elevator system to be constructed for the assembly platform, if possible, which remain in the elevator shaft even after assembly has been completed, in particular components of the elevator car, and for the components of the elevator system to be only temporarily supplemented with components that enable suspension and a controlled upward and downward travel of the at least partially assembled elevator car and can be reused several times. This increases the efficiency of the assembly process and the assembly is more sustainable.
  • the at least partially assembled elevator car used temporarily for assembly purposes can be optimized with an appropriately designed safety system from the point of view of a high level of safety for the assembly personnel.
  • the components of the safety system which supplement the components remaining in the elevator system or represent a self-contained system, can form a component package that is temporarily used on a elevator car during assembly work in an elevator shaft and then removed again to be used on a new construction site.
  • the component package enables sufficient safety for the assembly personnel, even if the elevator car has not yet been fully assembled and none or not all of the safety components present in the subsequent elevator system have been installed in the elevator shaft.
  • the technical effort for providing a reliable assembly platform can thus be limited to a level that sufficiently takes into account the safety interests of the assembly personnel, but also fully guarantees their safety.
  • the at least partially assembled elevator car is made capable of temporarily serving as an assembly platform by temporarily adding some additional components and installing a few other components in the elevator shaft.
  • the few special components from the elevator shaft and the car that were required to upgrade the at least partially assembled car to an assembly platform with which the assembly work to be carried out over the full height of the elevator shaft can be carried out.
  • the car can then be finally assembled in the elevator shaft, if this is still necessary.
  • the passenger winch to be attached to the lift car can be kept small and compact and is therefore easy to attach to and remove from the lift car, whether on the car roof or in the car above - on the ceiling side - and/or below - on the floor side.
  • the feature of the at least partially assembled lift car is to be understood in such a way that the lift car must already be constructed to such an extent that it has sufficient inherent stability to be able to safely carry at least one fitter and his tools.
  • the load-bearing capacity of the partially assembled lift car can in particular be sufficient to be able to carry at least two fitters and their tools.
  • the elevator car can already be used as an assembly platform, for example, if the elevator car floor, the elevator car frame and the elevator car roof have been assembled and one or more fall protection devices have been attached to the elevator car roof to cover any gap between the outer circumference of the elevator car and the shaft wall.
  • a lifting device is additionally mounted in the elevator shaft, the lifting device is used to transport components of the elevator system during further assembly, and the lifting device is removed from the elevator shaft again after the assembly work in the elevator shaft has been completed.
  • the lifting device is provided, with which, for example, elevator car and counterweight rails, doors, drive components, suspension cables and the like can be moved up and down within the elevator shaft.
  • the lifting device can be, for example, a material winch, a chain hoist or a comparable device.
  • the components listed can be used for moving the elevator system.
  • Components can also be installed in the elevator shaft in other ways, and the elevator car and the lifting device can also be used to install other elevator components.
  • the at least partially assembled elevator car is not burdened by the transport of heavier components and may even be overloaded. This increases the safety of the assembly personnel during assembly work.
  • the respective transport routes and means can be functionally optimized. While the design and mobility of the at least partially assembled elevator car can be optimized, for example, from the point of view of high safety for the assembly personnel, it is possible to design the lifting device to match the weight of the components to be installed in the elevator shaft, although safety requirements for a lifting device may not be as high as for a passenger winch. In this way, the technical effort can be limited to a level that sufficiently takes into account the safety interests of the assembly personnel, but is also designed to be able to move the heavy components of the elevator system reliably.
  • load-bearing elements have been mounted in the shaft head ceiling, to which at least one deflection roller, the Assembly rope, the lifting device and/or a fall stop rope can be attached.
  • the load-bearing elements mounted in the shaft head ceiling simplify the temporary conversion of the elevator car into an assembly platform.
  • the load-bearing elements can, for example, be concreted into the shaft head ceiling on site at low cost or fastened in the area of the shaft head ceiling using dowels or push-through fastenings before assembly of the elevator system begins.
  • the additional load-bearing elements mean that any other load-bearing elements required for the operation of the elevator system remain unused, so that they are freely accessible for assembly work.
  • the load-bearing elements can remain in the shaft head ceiling after assembly work in the elevator shaft has been completed. This means that the elevator can be dismantled again and a new elevator installed, thus ensuring sustainability.
  • the load-bearing elements can also be used for maintenance work.
  • components are used for the safety system at least in part which form a permanent part of the elevator system even after the assembly work in the elevator shaft has been completed.
  • An example of this is the safety gear, which must be present in a fully assembled, operational elevator system and which can form part of a temporary safety system when installed in a car.
  • a safety system is installed on the elevator car and in the elevator shaft, which includes a fall stop rope, a safety device, a Actuating device and a rod that connects the actuating device and the safety gear to one another.
  • the fall stop rope must be attached to a load-bearing element arranged on the shaft head ceiling in the elevator shaft and from there hang down to approximately the shaft floor.
  • the free end of the fall stop rope runs through the actuating device, which is connected to the safety gear mounted on the elevator car. If the elevator car moves downwards too quickly during assembly work, the actuating device triggers the safety gear, which slows down the downward movement of the elevator car and stops it completely.
  • the safety gear can be a component that remains permanently on the elevator car.
  • the safety gear as a component of the safety system then does not have to be removed from the elevator car and the elevator shaft after the assembly work in the elevator shaft has been completed.
  • an actuating device for the safety gear must also be installed on the car, with which the assembly personnel can manually trigger the safety gear themselves if necessary. Activation of the actuating device by the assembly personnel is transmitted to the safety gear via the rods.
  • the safety system has safety switches.
  • safety switches that can be considered are overload switches, slack rope switches, rail limit switches, protective space switches and the like.
  • the safety switches increase the operational safety of the Installation personnel. Since the safety switches are part of the safety system, they can be easily attached to the elevator car using the safety system and later removed from the elevator shaft after the installation work has been completed and then reused on a new construction site. If the safety switches detect a fault condition, such as an overload, a slack installation rope, an end of the rail or the narrowing of a necessary protective space, the personnel winch is automatically switched off and the movement of the elevator car is stopped.
  • a fault condition such as an overload, a slack installation rope, an end of the rail or the narrowing of a necessary protective space
  • the safety system has a trigger mechanism for producing an emergency opening, which can be set to a different trigger height.
  • An emergency opening serves the purpose of being able to leave the elevator shaft even if the elevator car can no longer be moved with the passenger winch.
  • the door cutout or part of it at the top stop in the elevator shaft can be considered as an emergency opening.
  • the emergency opening In order for the emergency opening to be large enough to allow a person to leave the elevator shaft through the emergency opening, the elevator car's journey must be safely stopped before the car completely or partially closes the emergency opening. Since the shaft heads on a construction site are always at different heights, the position at which the elevator car's journey is stopped must always be individually determined and set anew on a construction site. This is possible using a trigger mechanism that can be set to a different trigger height.
  • the safety system has a combination of a pressure-resistant element and a pressure-compliant element as a trigger mechanism.
  • the trigger mechanism can, for example, have a pressure-resistant element and an element that is flexible under pressure, such as a spring.
  • the pressure-resistant element can be a pipe, a sheet metal angle or another shaped body that is placed over the mounting cable. Both elements are attached to the mounting cable in such a way that it slides freely through them when the elevator car moves.
  • the pressure-resistant element and the pressure-compliant element are designed to be telescopic into one another, whereby the two elements can be fixed to one another in different extension positions. The different extension positions result in different trigger heights for the trigger mechanism.
  • the triggering works when the pressure-resistant element hits the pulley when the elevator car travels upwards.
  • the impact is transferred to the spring, which transfers the pressure to a switching element connected to the elevator car, which switches off the passenger winch when a pressure signal is received.
  • the elevator car remains immediately in its current position and the emergency opening remains sufficiently wide open.
  • the element which is flexible when pressed, prevents force peaks and vibrations in the elevator car and damage to the assembly cable when the pressure-resistant element hits the pulley and blocks further upward movement.
  • the elevator car is provided with the passenger winch in a position close to the ground in the elevator shaft, the elevator car rails are installed progressively from bottom to top, and the elevator car is guided by car rails that have already been installed in the elevator shaft during the assembly of the elevator car rails. If the elevator car is installed close to the ground, it does not yet have to be moved upwards within the elevator shaft. In the position close to the ground, the passenger winch can also simply be attached to the elevator car. The assembly cable is then transported at a first end over a passenger winch attached to the elevator car and laid loosely in the elevator car or loosely guided out of the elevator car and wound up and fastened under the elevator car and firmly connected to the elevator car at the second end.
  • the first car rail can also be installed in the elevator shaft without the installation staff having to move the car up in the elevator shaft.
  • the car and the car rail can already be installed in such a spatial relationship to each other that the car is already positioned in the path of movement intended for regular operation and is connected to the lower car rail in such a way that it is guided by it during a subsequent upward movement.
  • the installation staff then want to install another car rail at the top end of the car rail already installed close to the ground, the car can be moved in a movement guided by the already installed car rail up to the upper rail limit switch of this car rail. above. From this position of the car, the assembly staff can easily carry out the corresponding assembly work. This procedure is repeated until the last car rail is installed in the upper area of the elevator shaft.
  • the car rails and also the counterweight rails can be installed over the full height of the elevator shaft.
  • the car does not swing in the elevator shaft during the assembly work.
  • the assembly staff therefore have a firm footing on the car and can work safely.
  • the elevator car is suspended from the assembly cable in a suspension of at least 1:1.
  • the 2:1 suspension is often used for classic passenger transport in multi-storey buildings. It doubles the load-bearing capacity, but also halves the speed, which must be compensated for with a more powerful motor.
  • a 3:1 or 4:1 suspension can also be used. In these cases, only additional pulleys are required, which can easily be installed in the elevator shaft and, if necessary, on the car roof.
  • a motor lifting device is introduced into the elevator shaft for transporting the drive, which has a holder for receiving the drive, the motor lifting device is can be moved up and down in the elevator shaft using a lifting device, and the motor lifting device is held and guided on a guide rail via guide elements.
  • the lifting device can be, for example, a material winch, a separate chain hoist or a similar device.
  • the holder is suitably dimensioned and designed to accommodate a drive and to keep it non-slip during transport through the elevator shaft from the take-over position to the end position.
  • the motor lifting device has a stop to which the rope or chain connected to the lifting device can be attached. The motor lifting device is raised or lowered via the lifting device.
  • the guide elements can be designed in such a way that they not only guide the motor lifting device and the drive during transport through the elevator shaft, but also partially or completely support them in terms of weight.
  • the guide rail on which the guide elements are guided can be the car rail or the counterweight rail, which is located in the relevant section of the elevator shaft.
  • a separate guide rail can also be installed in the elevator shaft, which only serves the purpose of guiding the motor lifting device and, if necessary, supporting it. After the drive has been installed in its desired position, the motor lifting device can be removed from the elevator shaft again.
  • the motor lifting device has one or more joints, via which the bracket is pivotably connected to the rest of the motor lifting device in a horizontal plane. Due to the pivotable mounting, the unloaded bracket can be pivoted out of the elevator shaft in a horizontal direction to a floor or to a floor access on which the drive has been provided. There, the drive is easily accessible in order to connect it to the bracket and to fasten it. The bracket loaded with the drive is then pivoted back into the elevator shaft and transported with the motor lifting device to the height at which the drive plate is located, on which the drive is to be mounted in its position of use.
  • the bracket can be pivoted again via the joints in a horizontal direction so that the bracket with the drive is in a position above the drive plate in which the drive can be placed precisely on the drive plate and connected to it.
  • the bracket can then be swiveled back into the elevator shaft via the joints and then removed from the elevator shaft together with the motor lifting device.
  • Phases a) or b) serve to assemble the car to an assembly state in which the car can be used as an assembly platform, as well as to assemble the temporarily required components to make the car usable as an assembly platform.
  • phase c at least the car rails are installed in the elevator shaft, progressing from bottom to top.
  • the installation of the car rails is important in this phase because it means that the elevator shaft can be accessed with the car at its full height and assembly work can therefore be carried out from the car at the full height of the elevator shaft.
  • the counterweight rails can of course also be installed in this phase, although these must only be installed in the elevator shaft when the counterweight is to be connected to the cable.
  • phase d) it is advisable to install the drive in phase d) and therefore before phase e) because the shaft and car doors would interfere with the transport of the drive from the supply floor to the installation position. Components of the electrical installation could also be damaged.
  • the lifting device used to move the drive in phase c) can also have been installed in the elevator shaft during phases a) or b) and c).
  • phase f the assembly steps are then undertaken to be able to move the elevator car with its regular drive. Since the drive has already been installed in the elevator shaft, the cables in particular must now be installed. The counterweight rails and the counterweight itself can have already been assembled in one of the previous steps; if this has not yet been the case, assembly must now take place in phase f).
  • This rough structure of the assembly process means that the assembly time required can be significantly reduced. There is no need to erect scaffolding in the elevator shaft or install a separate assembly platform. However, the safety of the assembly personnel is guaranteed even when the elevator car is used as an assembly platform by installing the temporary safety system.
