Definitions

  • the invention relates to a method for planning and at least partially installing an elevator system in an elevator shaft according to claim 1.
  • Installation steps such as installing a component within an elevator shaft, have traditionally been performed by fitters or installation personnel.
  • a fitter goes to a location within the elevator shaft where the component is to be installed and installs the component at a desired location, for example, by drilling holes in a shaft wall and securing the component to the shaft wall with screws or bolts inserted into these holes.
  • the fitter may use tools and/or machines to do this.
  • individual installation steps can be automated, for example, by an automated assembly device.
  • the assembly device can, for example, drill holes at specified positions on the shaft walls of the elevator shaft and insert anchor bolts into the drilled holes.
  • the following steps, such as aligning and attaching guide rails using rail brackets and the aforementioned anchor bolts, can then be performed by an installer.
  • Rail brackets usually have a lower rail bracket section and an upper rail bracket section that can be screwed to the lower rail bracket section.
  • the lower rail bracket section is fixed to the shaft wall. For example, screwed on.
  • the guide rail is connected to the upper rail bracket section, which can be moved relative to the lower rail bracket section. This allows the guide rail to be aligned.
  • the division of labor between the automated assembly device and the installer can vary.
  • the WO 2017/016783 A1 describes an automated assembly device for performing an installation process in an elevator shaft of an elevator system and a method for performing an installation process using such an assembly device.
  • a support component with a mechatronic installation component is fixed in the elevator shaft at various heights.
  • the installation component performs various installation steps, such as drilling holes in a shaft wall of the elevator shaft.
  • WO 2017/016783 A1 focuses mainly on the implementation of the installation and does not deal in detail with its planning.
  • the EP 1 225 522 A1 describes a design system for an elevator product to be manufactured based on a specific order.
  • the EP 3 127 847 A1 describes a device and a method for determining the position of an installation platform in an elevator shaft.
  • the WO 2017/016780 A1 describes an automated assembly device for performing an installation process in an elevator shaft of an elevator system and a method for performing an installation process using such an assembly device.
  • this method before drilling a hole in a shaft wall of the elevator shaft, an image of the position of reinforcements within the shaft wall is created, and based on this image, drilling positions for the boreholes are determined.
  • the object of the invention is, in particular, to propose a method for planning and at least partially installing an elevator system in an elevator shaft, which enables the installation to be carried out as planned. According to the invention, this object is achieved by a method having the features of claim 1.
  • verifying that the automated installation steps can be performed by the assembly device ensures that the planned automated installation steps can actually be carried out. Ensuring the feasibility of the planned automated installation steps is also helped by planning the automated installation steps only after the actual layout of the elevator system has been derived. This allows changes from the target layout to the actual layout of the elevator system to be taken into account when planning the automated installation steps.
  • the installation of the The elevator system is continued by one or more technicians.
  • the technician aligns guide rails and secures them to the shaft walls, installs a drive, assembles a car, and performs all necessary electrical installations. It is also possible for individual installation steps to be performed by another automated assembly device.
  • the assembly device performs several installation steps automatically. It can perform a single installation step, such as drilling a hole in a shaft wall, multiple times at different locations in the elevator shaft, or it can perform several installation steps, such as drilling a hole and inserting an anchor bolt into the hole. Even if different installation steps are performed, they are often performed multiple times at different locations in the elevator shaft.
  • the assembly device has, in particular, a carrier component and a mechatronic installation component.
  • the carrier component is designed to be displaced relative to the elevator shaft, i.e., for example, within the elevator shaft, and to be positioned at different heights within the elevator shaft.
  • the installation component is held on the carrier component and designed to carry out an installation step within the installation process at least partially automatically, preferably fully automatically.
  • the installation component is designed, for example, as an industrial robot.
  • the assembly device has, in particular, a displacement device, by means of which the carrier component can be displaced in the elevator shaft, and a fixing component for fixing, in particular caulking, the carrier component in the elevator shaft.
  • the assembly device has, in particular, a control device for controlling the individual components of the assembly device.
  • the assembly device is, for example, configured according to a WO 2017/016783 A1 described assembly device.
  • Deriving a target layout for the elevator system from the target dimensions of the elevator shaft is primarily performed by a planner, who is supported in particular by a special computer-aided planning tool. This derivation can also be carried out fully automatically using a corresponding computer-aided tool.
  • the starting point for deriving the target layout are the target dimensions of the elevator shaft, such as the width, depth, and height of the elevator shaft, the number of floors, and the dimensions of door cutouts.
  • the target dimensions of the elevator shaft can be taken from construction plans of the building containing the elevator shaft. It is also possible for the target dimensions of the elevator shaft to be derived from a digital building model of the corresponding building.
  • the target layout of the elevator system specifies, for example, the arrangement of a counterweight (next to or behind the elevator car), the size of the elevator car, the type and number of guide rails, the arrangement and design of the drive machine, and the type and design of any support means (e.g., steel cables or belts).
  • the target layout can have a lower level of detail than the actual layout subsequently derived from it. For example, it is possible that the target layout only specifies the arrangement of the counterweight and the size of the elevator car.
  • the determination of the installation steps to be carried out by an automated assembly device is also carried out by a planner. However, this step can also be fully automated. In this context, the planner also specifies which assembly device should be used to carry out the automated installation steps.
  • the planner's particular task is to plan the installation of the elevator system so that it can be carried out as quickly and/or cost-effectively as possible.
  • different installation steps can be carried out automatically. For example, in some cases it may be advantageous to only drill holes for fixing guide rails and insert the corresponding anchor bolts automatically; in other cases it may be advantageous to drill holes automatically and fix so-called rail bracket bases for fixing guide rails to the shaft wall using corresponding screws.
  • the determination of the automated installation steps also depends on the available automated assembly devices. There may be different versions of mounting devices that can perform at least partially different installation steps. It is also possible For example, due to the dimensions of the elevator shaft, only a specific version of the mounting device can be used, which can also influence the determination of the automated installation steps.
  • the automated installation steps can be defined independently of the target layout of the elevator system. This is the case, for example, if the same installation steps are always performed automatically for all possible elevator system layouts. For example, it can be specified that holes are always drilled by an automated assembly device, and that the assembly device always inserts anchor bolts into the drilled holes. Thus, only adopting this specification is necessary to define the automated installation steps.
  • the dimensions of the intended automated assembly device are compared with the dimensions of the elevator shaft.
  • the assembly device is designed to be flexible enough, for example, that a fixing component for fixing the support component can be adapted to different dimensions of the elevator shaft within certain limits. Such adaptations are planned or specified, in particular, within the scope of this process step.
  • the installation component can reach all necessary locations in the elevator shaft.
  • the check to determine whether the automated installation steps can be carried out by the assembly device is carried out, in particular, based on the target dimensions of the elevator shaft and the target layout of the elevator system.
  • the aforementioned inspection is carried out based on the actual dimensions of the elevator shaft and the actual layout of the elevator system. It is not absolutely necessary that the above-mentioned test is carried out on the basis of the target layout of the elevator system.
  • the process steps described so far can be carried out based on the target dimensions of the elevator shaft and thus independently of the actual elevator shaft in which the elevator system is to be installed.
  • the recording of some actual dimensions of the elevator shaft must be carried out at or in the elevator shaft.
  • the actual dimensions can be recorded manually by a planner or installer, for example.
  • the planner or installer measures the width and depth of the elevator shaft at different heights and/or checks whether the dimensions of the door cutouts correspond to the target specifications. It is also possible to measure the entire elevator shaft using an automated measuring system.
  • the measuring system can, for example, be designed like a WO 2018/041815 A1
  • the measuring system described above must be implemented.
  • the aim of the recording or measurement is to determine any deviations from the nominal dimensions of the elevator shaft.
  • the dimensions of the elevator shaft can also include surface properties, particularly the shaft walls, or holes and local elevations in the shaft walls.
  • the dimensions of the elevator shaft here also include the layout of reinforcements in the shaft walls of the elevator shaft. This means that when recording actual dimensions, the layout of reinforcements can also be detected and documented using a suitable sensor, for example, integrated into a digital model of the elevator shaft.
  • the derivation of an actual layout of the elevator system from the target layout of the elevator system and the recorded actual dimensions of the elevator shaft is also carried out by a planner, a fitter, or fully automatically.
  • the goal is to adopt the target layout as the actual layout of the elevator system.
  • it is checked whether the target layout can be implemented in the real elevator shaft defined by the actual dimensions. For example, it is checked whether the planned size of the elevator car is compatible with the actual dimensions of the elevator shaft.
  • the check can, for example, include all specifications of the target or actual layout. If this is the case, the target layout is adopted as the actual layout of the elevator shaft. If this is not the case, adjustments to the layout are made according to the actual dimensions of the elevator shaft.
  • the size of the Elevator cabin can be adapted.
  • all other specifications of the target or actual layout can also be adjusted. If the automated assembly device requires reference elements to determine its position in the elevator shaft, for example, in the form of cords stretched in the elevator shaft, their position is also determined in this process step.
  • the assembly device is removed from the elevator shaft and the installation is continued, in particular by a fitter, by hand or with the assistance of tools.
  • the planners or fitters mentioned can be a single person or several different people.
  • a digital model of the elevator shaft is created using the recorded actual dimensions of the elevator shaft. This allows for a particularly accurate derivation of the actual layout from the target layout of the elevator system.
  • the actual layout of the elevator system can be integrated into the digital model of the elevator shaft and thus mapped particularly accurately.
  • a digital model of an elevator shaft is specifically understood to mean a CAD model of the elevator shaft, which may also contain additional information.
  • the level of detail of the digital model of the elevator shaft can vary. For example, only a few dimensions of the elevator shaft may be measured by hand, and the digital model created based on these. However, it is also possible for the entire elevator shaft to be measured very precisely using an automated measuring system, and for the digital model to be derived from the resulting point cloud.
  • the digital model of the elevator shaft can be integrated into a digital building model and blueprints of the building containing the elevator shaft.
  • a further check is performed to determine whether the automated installation steps can be performed by the assembly device. This constitutes a second check of the feasibility of the automated installation steps. This particularly reliably ensures that the automated installation steps can actually be performed. Feasibility is ensured even if the actual layout of the elevator system differs from the target layout.
  • the assembly device uses a suitable sensor to check, before carrying out an upcoming installation step, whether the installation step can be carried out as planned.
  • a suitable sensor for example a laser scanner for distance measurement or a sensor for detecting reinforcements in a shaft wall.
  • This sensor is used to more closely examine the intended position at which the installation step is to be carried out, for example, a hole is to be drilled and a rail bracket base is to be mounted.
  • the laser scanner it can be checked, for example, whether there are any local unevennesses, such as holes or edges, in the shaft wall at the intended position that could make the planned implementation of the installation step difficult or impossible.
  • the sensor for reinforcement detection can be used, for example, to check whether there is reinforcement at the intended position that would prevent a hole from being drilled at the intended location. Positioning is difficult or impossible.
  • the positioning of the sensor and the evaluation of the acquired sensor data are carried out primarily by the control device of the mounting device.
  • the installation step will be carried out as planned. If the feasibility check is negative, the implementation will be rescheduled so that the installation step can be carried out, and the rescheduled installation step will then be carried out as planned. This ensures the feasibility of the installation step with particular certainty.
  • the intended position for the installation step is shifted within permissible limits so that the installation step can be carried out.
  • the intended position is shifted so that a detected reinforcement no longer interferes with the drilling of a hole.
  • additional installation step for example, a raised area at the specified location can be removed using a chisel, allowing the originally planned installation step to be carried out without being affected by the raised area.
  • an installer in the event that replanning while adhering to specified specifications is not possible, can specify the implementation of the installation step and start the execution. The installer can then, using his experience, decide that implementation of the installation step is justifiable even without adhering to the specified specifications.
  • a specified specification can, for example, be that in a certain
  • the installation device would only automatically carry out the installation step of drilling a hole in the shaft wall if this requirement is met. However, if reinforcement is present, for example, at the edge of the specified area, the installer can decide to take the risk that the drilling might not be successful and drill the hole in the intended position anyway.
  • the installer can adapt the implementation process to the one planned by the installation facility. This allows them to contribute their experience to the implementation process.
  • the installer can change the sequence and initiate the installation step directly via an input on the control device of the assembly device. It is also possible for the control device of the assembly device to have an interface through which the installer can remotely access the control device, for example, via a mobile phone app, and change the sequence and initiate the installation step.
  • the digital model of the elevator shaft is adjusted using the sensor data acquired by the sensor. This enables the creation of a particularly accurate digital model of the elevator shaft.
  • the type of adjustment depends on the type of sensor used. If distances to the shaft wall were measured using the sensor, the masses of the elevator shaft contained in the digital shaft model are adjusted locally. If reinforcements in a shaft wall were detected using the sensor, the information about the reinforcements is incorporated into the digital model of the elevator shaft.
  • an assembly protocol is automatically created for the automatically performed installation steps.
  • the assembly log can be viewed as part of the model of the elevator shaft and thus a building model of the corresponding building. This means that the installation is logged and documented without any additional effort.
  • the assembly log can, for example, be evaluated and used for subsequent installation steps carried out by an installer. For example, the installer can use the assembly log to obtain information about which automated installation steps require manual rework.
  • the assembly log can also be saved for documentation purposes.
  • the assembly log is created in particular by the control device of the assembly device and saved in such a way that it can be retrieved later.
  • the assembly log contains, for example, information about the exact positions at which the installation steps were carried out and/or about the successful or unsuccessful completion of the automated installation steps.
  • a simulation of the automated installation step is carried out. This makes it possible to check particularly precisely whether the planned automated installation steps can actually be carried out.
  • a computer-aided simulation tool is used in which the assembly device and the elevator shaft are modeled.
  • a simulation of the individual automated installation steps is then carried out.
  • a planner or an automated system can check whether the installation steps can actually be carried out or whether, for example, there are collisions between the installation component and the elevator shaft or the support component.
  • the insertion of the assembly device into the elevator shaft can also be simulated.
  • a position is determined by a marker located on the elevator shaft.
  • the markers can be located in the elevator shaft or in or directly next to the Door cutouts of the elevator shaft. The recording and evaluation of these markings can also be advantageously carried out independently of the procedural steps for planning and at least partially installing an elevator system in an elevator shaft.
  • the markings can, for example, indicate building axes, particularly a vertical axis. Based on the building axes identified by the marking, the digital model of the elevator shaft can be correctly aligned. It is also possible for the aforementioned marking to indicate a defined height, for example, a so-called meter mark. The meter mark indicates a vertical distance of 1 m from the top edge of the finished floor. From this, for example, the correct position of an elevator shaft door can be determined very precisely.
  • a reinforcement plan of the elevator shaft walls is taken into account when deriving a target layout for the elevator system. This allows the target layout to be derived in such a way that as few problems as possible arise with the reinforcements in the shaft walls during installation of the elevator system.
  • a reinforcement plan contains information about the locations and, in particular, the depth at which reinforcements run in the shaft walls. The target layout is thus defined, for example, so that no holes need to be drilled where reinforcements are present.
  • reinforcing bars run vertically in shaft walls, which are connected to horizontal reinforcing bars in the ceiling area by means of special brackets.
  • the guide rails are defined in the target layout in such a way that no rail bracket bases need to be fixed to the shaft walls in the ceiling area.
  • the guide rails can have a length that corresponds approximately to the distance between the ceilings of the building in which the elevator shaft is located. The guide rails can then be fixed in such a way that they always abut one another in the area of a ceiling of the building.

  • a position of the mounting device is determined using a reference element arranged in the elevator shaft, and the mounting device carries out automated installation steps.
  • a fitter aligns guide rails of the elevator system to an alignment element arranged in the elevator shaft and then fixes them in place.
  • a course of the alignment element is determined based on a course of the reference element and the actual layout of the elevator system, and information on the course of the alignment element is made available to the fitter. This allows the fitter to arrange the alignment element in the elevator shaft very quickly and without having to measure the elevator shaft.
  • two reference elements are used in the first installation phase and two alignment elements are used in the second installation phase, all of which are designed in particular as cords and run mainly in a main extension direction of the elevator shaft.
  • the main direction of extension of the elevator shaft is understood here to be the direction in which an elevator car of the fully assembled elevator system travels.
  • the main direction of extension is therefore generally vertical, but it can also be inclined relative to the vertical or horizontal.
  • the main direction of extension does not necessarily have to run along a single straight line along the entire length of the elevator shaft.
  • the main direction of extension can also be composed of straight sections, the transition areas of which can also be rounded.

  • the alignment of the guide rails to the alignment elements can be determined, for example, according to a method described in WO 2015/091419 A1 described procedures.
  • Information about the alignment element's path can be provided to the installer in a variety of ways. For example, distances between the alignment element and the reference element can be output for two different heights, which can then be manually adjusted and measured. A special gauge can also be used for setting the specified distances. If both the reference element and the alignment element are exactly vertical, outputting the specified distances is only sufficient for one height.
