Description

The invention relates to a scaffold transport system, a method for controlling a scaffold transport system and the use of a scaffold transport system and/or a method for controlling a scaffold transport system.

It is known from the prior art that when erecting or dismantling scaffolding, additional lift systems are used, via which material can be delivered to higher scaffolding levels of the scaffolding. The scaffolding planes each represent horizontal planes. The material can be additional scaffolding material or building material. The lift systems known from the prior art are usually set up separately from the scaffolding, for example in the form of a freight elevator, so that the material required can be delivered in the vertical direction. As an alternative to the lift systems, cable winches are used, some of which are mounted on the scaffolding, for example via their gears. The cable winches are also intended to transport the material to be transported from the ground to a higher scaffolding level in a vertical direction.

Usually, the lift systems or cable winches are loaded on the ground by staff at a loading position in order to deliver the relevant material to a higher scaffolding level, where the delivered material can be removed again at an unloading position, i.e. the lift system is unloaded. Employees are required for loading and unloading, for example workers who load and unload the material. The unloaded material is then carried to the place of use by the workers in the respective scaffolding level. Depending on the size of the scaffolding, multiple workers and possibly multiple lift systems are required to efficiently move the material from the unloading location to the point of use. This applies analogously to the transport of the material from a delivery location, where, for example, a truck with the corresponding material to be transported is parked, to the loading position.

From the DE 298 08 022 U1 a classic scaffold transport system with a rail system and a chassis is known, which can be pulled by hand along a horizontal rail section.

The WO 2012/006694 A1 shows a scaffolding transport system having horizontally extending rails over which a wheeled carriage can be slid, with the wheels resting on the rails.

In the DE 699 01 777 T2 describes a bridge-like conveyor system for crossing roads.

From the DE 22 32 739 A1 a paternoster-like lift device is known.

The object of the invention is to provide an efficient scaffolding transport system with which it is possible to efficiently deliver, inter alia, building material to the desired positions and locations of a scaffolding, for example during erection and dismantling of the scaffolding.

The object is achieved according to the invention by a scaffolding transport system according to claim 1 with a rail system which has at least one horizontally running rail section and at least one carriage module which is set up to move along the rail system, the carriage module having a coupling section via which the carriage module is captive and movably coupled to the rail system and having a support portion over which the carriage module supports objects during movement. The rail system has at least one vertically running rail section which is coupled to the horizontal rail section. A system controller is provided, which is set up, among other things, to control the movement of the at least one carriage module along the rail system. The system controller is designed to access sensor values in order to control a movement of the at least one carriage module along the rail system. The carriage module is designed as a robot, the movement sequences of which are controlled by the system controller. The slide module has a drive that ensures that the Carriage module automatically moves along the horizontal rail section and along the vertical rail section. The scaffold transport system includes a scaffold. The rail system comprises a plurality of modular rail elements which are attached to the framework by means of fasteners and which form the rail sections. In addition or as an alternative, the framework has framework elements, with the rail system being formed via the framework elements into which the rail sections are integrated.

The basic idea of the invention is that the scaffolding transport system can transport objects in a corresponding scaffolding level of a scaffolding to the desired place of use in an efficient and automated manner due to the horizontal rail section. For this purpose, it is no longer necessary to resort to the manpower of personnel, for example that of a worker, which means that the efficiency in the transport of the corresponding material can be increased. The efficiency is increased to the extent that time-consuming and physically demanding work, i.e. the transport of objects such as scaffolding material in a specific scaffolding level, is automated via the scaffolding transport system. Manual intervention is no longer necessary. At the same time, transport safety is increased since human error during the transport of objects, for example building and/or scaffolding material, which could lead to damage to the corresponding objects or the periphery or to accidents involving people, is avoided. At the same time, due to the increase in efficiency and the inherent improvement in safety, the cost can be reduced because the effort and time required can be reduced. The scaffold transport system can therefore result in improved construction site logistics.

The scaffolding transport system can be used in general for various types of scaffolding or scaffolding, for example for tubular-coupler scaffolding, work scaffolding, protective scaffolding, fixed scaffolding, suspended scaffolding, trestle scaffolding, mobile scaffolding, facade scaffolding, spatial scaffolding, stair towers, free-standing scaffolding, industrial scaffolding, cable bridges, event scaffolding and/or Special constructions, which are used, among other things, in civil engineering, in industrial plant construction, in road construction, in bridge construction, in vehicle construction, in shipbuilding, in Structural engineering, in carpentry, in engineering timber construction, in special construction, in civil engineering, in earthworks, in regional culture construction, in hydraulic engineering and/or in special construction.

A scaffold is usually a temporary, reusable auxiliary construction made from standardized scaffolding elements, for example rods and/or tubes made of metal or wood, for example bamboo. However, permanent scaffolds are also known which are designed for continuous operation, for example in special or special construction or in special applications such as tower scaffolding.

Since the rail system has at least one vertically running rail section, which is coupled to the horizontal rail section, the carriage module can be moved along the two rail sections. The two rail sections can cross, with the carriage module being designed in such a way that it can travel over the intersection of the vertically running rail section and the horizontal rail section. As a result, the manual transport of building material or scaffolding material from scaffolding level to scaffolding level can be simplified, since the time-consuming and physically demanding work is automated.

The vertical rail section can be installed first when installing the rail system, running vertically along the scaffolding from the ground. Starting from a loading position provided on the floor of the scaffolding, the rail system can then be expanded. In particular, the first vertically running rail section initially extends as far as the horizontal rail section.

In general, the rail system has a number of rail sections running vertically and a number of rail sections running horizontally, so that the carriage module can reach as many positions as possible in the rail system in order to transport objects to the appropriate locations, for example the places of use. The multiple track sections may cross, creating multiple intersections at which the carriage module may change its direction of travel.

The at least one vertically running rail section and/or the at least one horizontally running rail section are or is in particular designed to be stationary. This means that the corresponding track section is immobile.

The drive ensures that the carriage module moves automatically along the corresponding rail section, i.e. it is not pulled along the corresponding rail section by a (pulling) cable or a person.

In particular, the drive is integrated in the carriage module, ie it is arranged within a housing of the carriage module.

The drive can be an electric motor that converts electrical energy into a mechanical movement of the slide module.

The energy supply for the drive can be ensured via at least one battery, for example a Li-ion battery. The battery is designed in particular as an accumulator.

Accordingly, the rail system can be constructed using separately designed rail elements which can be attached to a framework, in particular subsequently. The modular structure of the rail elements ensures that the rail system can be expanded by adding further rail elements. In particular, the rail system can grow with the scaffolding during its construction, which ensures that all desired locations and positions of the scaffolding can be reached. Since the rail elements, which are designed separately, can be coupled to existing, standardized scaffold elements, it is possible to retrofit the scaffold transport system.

The attachment means provided for attaching the rail elements can also be of modular design, so that they can be easily attached to the different attachment points of a scaffold. These can be snap connections or the like. Couplings commonly used in scaffolding are also suitable, for example standard couplings, rotary couplings and/or butt couplings. The fastening means can also be realized by pipe and plug connections, screw or clamp connections, carrier clamps and module node connections be. The corresponding fastening means can be coupled to the coupling section of the scaffolding, for example to rosettes that are commonly used.

In general, all fastening or connecting means can be in the form of the above-mentioned couplings, clamps or connections.

According to another embodiment, the rail system is provided via the scaffolding itself, which has appropriately designed scaffolding elements that integrally comprise rail sections required for the rail system. For example, the modular scaffolding elements are rods or tubes that each form a corresponding rail section. When assembling the scaffolding, the rail system is expanded accordingly at the same time.

In general, the rail elements can also include rail curve elements. The rail curve elements are provided, for example, to connect two horizontally running rail sections that intersect essentially at right angles. Accordingly, the rail system can be expanded via the rail curve elements in such a way that the rail system is essentially L-shaped in its plan view. This makes it possible, for example, for the rail system to extend over scaffolding that is set up along a building facade that has a corner. The L-shape of the rail system corresponds to two two-dimensional rail networks arranged essentially at right angles. The rail curve element ensures that the carriage module can move efficiently along the rail system, since a right-angled connection of the two two-dimensional rail networks would require at least a complete stop of the carriage module. Due to the rail curve element, which is provided for connecting the two two-dimensional rail networks that intersect essentially at right angles, the carriage module can change the corresponding planes formed by the rail networks without being completely stopped. It is generally possible via the rail curve elements for the rail system to be three-dimensional, for example L-shaped.

The rail system can generally be designed in such a way that it connects two horizontally running rail sections that intersect essentially at right angles. This can be implemented via at least one rail curve element or another transition mechanism.

Alternatively or additionally, the rail system can be designed in such a way that it connects two rail sections that essentially intersect at right angles and that run vertically in their corresponding two-dimensional rail network. For example, the carriage module travels along a vertical rail section of a first rail network to its end, and then changes to another two-dimensional rail network that is perpendicular to the first. This is the case when the carriage module is moved upwards along a wall, the wall representing the first two-dimensional rail network, and then proceeding on a ceiling, which represents the second two-dimensional rail network perpendicular to the first. This transition can also be implemented via at least one rail curve element or another transition mechanism.

In general, the rail elements or the frame elements having rail sections form movement paths for the at least one carriage module, along which the carriage module can move in order to transport objects.

According to one aspect, the rail system has at least one two-dimensionally closed rail system area, in particular several rail system areas connected to one another being provided. The rail system areas represent a two-dimensional rail network in which the slide module can move. The rail system is therefore arranged in a plane that corresponds to the front of the corresponding scaffold. This plane is essentially perpendicular to the ground. The two-dimensional rail network is thus spanned in the vertical and horizontal direction, i.e. in the corresponding plane, so that the carriage module can move up, down, to the left and to the right in the closed, two-dimensional rail network.

The carriage module can be moved along a closed rail track of the rail system, which at least includes, in particular forms, the closed, two-dimensional rail network. The carriage module can move to a loading position and an unloading position, which are located along the closed rail track, in order to be loaded or unloaded.

The support section can be of modular design, so that different load handling units can be coupled to the support section. The load handling units can be load handling units specific to the object to be transported. If a large object is to be transported, a load handling unit designed specifically for this purpose can be coupled to the corresponding carrying section, so that safe transport of the object is ensured. Correspondingly, several small objects can be safely transported in another load-carrying unit, which can also be coupled to the support section. Due to the modular structure of the support section, it is ensured that the different load handling units can be coupled to the carriage module in a simple manner. In addition, a load handling unit can be designed in such a way that several different objects can be transported with it. The modular support section ensures that the selected load handling unit can be coupled to the corresponding support section of the carriage module in a simple manner and thus in a short time, whereby the efficiency of the scaffold transport system is correspondingly increased.

The objects to be transported, which are transported via the carriage module along the rail system, can be building material, scaffolding material, people, tools and the like. Correspondingly differently designed load handling units can be provided for the different objects.

In general, the load-carrying units can be designed in such a way that the objects to be transported are secured in the corresponding load-carrying units. This can be done via appropriate locking or securing mechanisms that have the load handling units.

According to one embodiment, the coupling section comprises at least one gripping unit, via which the carriage module is captively coupled to the rail system, and/or at least one sliding unit, via which the carriage module slides along the rail system. The gripping unit and the sliding unit can together form a gripping-sliding mechanism of the carriage module, via which the correspondingly safe movement of the carriage module along the rail system is possible. The gripping unit can be designed in such a way that it at least partially encompasses the rail elements or sections of the rail system in order to be coupled to the rail system in a correspondingly captive manner. For this purpose, the gripping unit includes a correspondingly designed gripping section.

The sliding unit can have a profile roller or a profile wheel, with the profile interacting with correspondingly designed rail elements or sections. For example, the rail elements or sections have a repeating hole pattern that corresponds to the profile of the sliding unit. The profile may include projections that engage the openings.

The sliding unit can be coupled to the drive, the drive mechanically driving the sliding unit, in particular the profile roller or the profile wheel.

Alternatively, the sliding unit and the correspondingly designed rail elements or sections are formed by a rack and pinion drive system, in which the rail elements or sections are rack-like. Consequently, the rail elements or sections have regular projections with which the sliding unit interacts, in particular the profile roller or profile wheel of the sliding unit.

In general, the sliding unit and the rail elements or sections each have corresponding structures which can be provided on associated surfaces.

The correspondingly designed structures of the sliding unit and the rail elements or sections, for example the rack and pinion drive system, are provided in particular for the vertically running rail elements or sections. This allows a vertical in a simple manner Ensure movement of the slide module. The horizontal rail elements or sections can also be designed accordingly.

The movement of the carriage module along the horizontally running rail elements or sections can also take place via rollers, tires or the like, which are also part of the sliding unit.

In particular, the gripping and sliding mechanism ensures that the carriage module can be coupled to the rail system in a simple manner. The carriage module can be attached to a rail element of the rail system in a simple manner, for example as a "plug-and-play" module. For this purpose, the carriage module can be pressed against the rail element via the gripping unit and/or the sliding unit, as a result of which the gripping mechanism of the gripping unit is activated. As an alternative or in addition, the gripping mechanism can be activated manually using a correspondingly designed button, using sensors, or in some other way.

In particular, the gripping-sliding mechanism and the corresponding gripping and sliding units ensure that the carriage module can travel over crossings of the rail system at which vertically running rail sections and horizontally running rail sections intersect.

The gripping unit can comprise at least one length-adjustable arm which has a free end on which a rolling element is provided. During the movement of the carriage module, the rolling element rolls off the rail element or section. The arm together with the rolling element ensures that the rail element or the rail section is at least partially encompassed.

In particular, the gripping unit includes two arms with corresponding rolling elements.

The two arms can be assigned to opposite sides in relation to the respective rail element or the respective rail section, so that the respective rail element or the respective rail section is partially encompassed by two opposite sides.

Alternatively or additionally, the two arms can be arranged at the front and rear in the direction of movement of the carriage module, so that the carriage module when driving over crossing rail sections, it always rests with at least one rolling element on a rail element or rail section. This ensures that the slide module is held captive.

In general, the at least one carriage module is thus held exclusively on the at least one rail section, in particular the associated rail element.

According to one embodiment, the carriage module comprises four gripping units arranged in two pairs. The pairs each define a direction of movement of the carriage module, so that two directions of movement are provided which intersect, in particular at right angles. An activated gripping unit is sufficient to ensure the captive movement of the slide module along the rail system.

Other embodiments may include fewer gripping units, such as two, or more gripping units. This depends in particular on the area of application.

The carriage modules may include a direction changing mechanism. The direction change mechanism can be formed via the gripping-sliding mechanism, ie the at least one gripping unit and the sliding unit, in particular the gripping units. For example, the carriage module is moved along the direction of a first pair until the carriage module stands on the intersection of a horizontally running rail section and a vertically running rail section. In this position, at least one gripping unit of a second pair, which previously did not grip the rail system, is activated so that the at least one gripping unit of the second pair grips the rail system at least partially. Then the active gripping unit of the first pair or the active gripping units of the first pair are released, so that the carriage module is captively coupled to the rail system only via the at least one gripping unit of the second pair. The carriage module can then be moved along the direction of movement that is defined by the second pair, ie perpendicular to the previous direction of movement.

In general, the speed of the carriage module can be reduced before a change of direction in order to ensure that the gripping units securely grip the corresponding rail elements or sections.

Alternatively, provision can be made for the rail system to have a direction-changing mechanism in which the crossings between horizontally and vertically running rail sections are formed by crossing sections which are designed to be rotatable. If a carriage module has reached a crossing or is standing on the corresponding crossing section, it can be rotated (for example by 90°) in order to change the direction of movement of the carriage module. The crossing sections can be controlled accordingly by a system controller.

According to one embodiment, multiple carriage modules are provided. The multiple carriage modules can be moved simultaneously in the rail system while being spaced from each other so that a safe distance is ensured. A collision between two slide modules is thus effectively prevented. The individual carriage modules can carry different objects, depending on which load handling unit is arranged on the corresponding carrying section of the carriage module. In this way, a continuous material flow can be achieved, as several slide modules with appropriately equipped load handling units move in the rail system at the same time.

The system controller can access sensor values in order to control an optimal movement of the at least one carriage module along the rail system. The sensor values are, for example, the positions of people who wear corresponding transmitters. As a result, the positions or locations to be controlled can be determined by control technology. Furthermore, the rail elements can include sensors that enable the system controller to detect the rail system that has been set up. For example, the system controller creates a (two- or three-dimensional) model of the rail system in order to calculate optimized trajectories for the at least one carriage module. The rail system can also be stored in terms of control technology using reference points, for example by providing sensors or transmitters at the crossings. There between the crossings linear movement paths are present in each case, the system control can determine these automatically or provide the movement paths to be followed along the reference points.

The sensors can be external sensors that have been subsequently attached to the corresponding rail elements or at least have been assigned to the rail elements.

The system controller may include a real-time position sensing unit configured to automatically sense the positions of people, such as workers, and/or carriage module(s). Accordingly, the system controller can automatically coordinate the movements of the individual carriage modules to prevent collisions or interference between the carriage modules and/or the workers. The calculations and execution of the corresponding movement sequences of the carriage modules can take place in an automatic manner, so that the most efficient possible transport of the objects to be transported via the individual carriage modules to the corresponding places of use is ensured.

The individual carriage modules are therefore designed as robots whose movement sequences are controlled by the system controller. The system controller can function as a central system unit that controls the carriage modules. Alternatively, the system control can be formed by many individual control modules, each of which is integrated in a carriage module. The multiple control modules then together form the system controller, communicating with one another.

The individual slide modules each have, for example, an (integrated) control module that receives control commands and implements them accordingly.

Furthermore, the control modules of the individual carriage modules can be designed to generate the control commands.

This results in the at least partially automated movement of the at least one carriage module along the rail system.

In general, the system controller can take into account safety protocols that are applied when the corresponding movement commands for the carriage modules are generated, ie the commands to the carriage modules are generated along which movement paths of the rail system the carriage modules are to move. For example, the system control includes the prioritized safety protocol, according to which a sufficiently large safety distance between the carriage modules and people, in particular workers, must be maintained if the carriage modules are moving.

The system control can also include collision detection for unforeseen objects in the movement paths, remote emergency control, sensor override detection and/or a manual intervention option, for example a manually operated switch, to start or end the system.

The collision detection is implemented using sensors, for example infrared sensors and/or optical sensors, which are arranged on the respective carriage modules. The sensors record corresponding data and transmit this to the system controller or to the system modules that are provided in the respective carriage modules.

The remote emergency control is used to interrupt the scaffold transport system in an emergency. Remote emergency control can also be provided to return the individual carriage modules to their previous positions. The previous positions are defined as the positions where the carriage modules last stopped, usually loading and unloading positions.

The sensor override detection is provided, for example, via sensors provided accordingly on the carriage modules, which record undesired operating states and transmit the recorded data accordingly to the system controller. The sensors can be pressure, temperature, acceleration and/or gyro sensors.

In general, the carriage modules can include other sensors in addition to the sensors mentioned.

The possibility of manual intervention is given in particular on each carriage module, so that the operators, especially workers, the entire Can control, stop and/or start the scaffold transport system if they operate the carriage module accordingly. This will usually be the case in the unloading and loading positions where the carriage modules come to rest.

In particular, the possibility of intervention ensures that the stand transport system, in particular the system control, is informed that the corresponding carriage module has been loaded or unloaded, so that it can be moved.

The control panel may have artificial intelligence or machine learning technologies so that it learns automatically as it operates.

For example, the scaffolding transport system, in particular the at least one carriage module, collects data on the process of scaffolding assembly during its operation, such as the amount of weight transported, waiting times of at least one worker and/or the at least one carriage module, type of activity, time required for loading or unloading Unloading of the at least one carriage module, time required for the transport of scaffolding parts and idle time, start and end of working hours, time and number of safety problems detected by the scaffolding transport system, in particular the system controller, and other data based on sensors and the interaction of the carriage module with the workers develop.

Furthermore, the scaffolding transport system can include a sensor, for example a visual, ultrasound-based or other type of sensor, which is set up to detect scaffolding parts, so that the scaffolding transport system is set up to count the number of scaffolding parts used, in particular depending on the type.

The workers who work with the scaffolding transport system can be equipped with a wearable device so that steps, height and other data can be recorded and/or stored. The data can be reconciled with the at least one sled module.

All (recorded) data can be stored in a data processing unit, for example a cloud server. About this Present data to the operator of the scaffolding transport system in an edited manner, for example on a website.

The data can be coordinated with the data processing unit, for example the cloud server, as an alternative or in addition to the at least one carriage module.

Furthermore, the invention is achieved by a method according to claim 6 for controlling a scaffolding transport system, with a rail system which has at least one horizontally running rail section and at least one vertically running rail section which is coupled to the horizontally running rail section, at least one carriage module and a system controller, which is set up, among other things, to control the movement of the at least one carriage module along the rail system. The system controller is designed to access sensor values in order to control a movement of the at least one carriage module along the rail system. The carriage module is designed as a robot whose motion sequences are controlled by the system controller, the carriage module having a drive that ensures that the carriage module automatically moves along the horizontal rail section and along the vertical rail section. The scaffold transport system includes a scaffold. The rail system comprises a plurality of modular rail elements which are attached to the framework by means of fasteners and which form the rail sections. In addition or as an alternative, the framework has framework elements, with the rail system being formed via the framework elements into which the rail sections are integrated. The method also includes the following steps:

• Loading the slide module in a loading position,
• Moving the carriage module along the rail system, and
• Unloading the carriage module in an unloading position.

It is thus possible to efficiently and automatically transport objects with the carriage module in a horizontal plane, for example a scaffolding plane, if the carriage module runs along the horizontal plane Rail section is moved. The rail system is formed by the frame or at least attached to the frame.

Since the rail system comprises at least one vertically running rail section in addition to the horizontal rail section, it is also possible to move the carriage module in a plane of movement that is perpendicular to a horizontal plane. The carriage module can therefore move objects along the scaffolding, i.e. in a horizontal and vertical direction.

The rail system can also have a two-dimensionally closed rail system area, which makes it possible to load and unload the at least one carriage module in a repetitive process. In the case of the closed rail system area, it is particularly possible to use several carriage modules, so that a higher cycle rate is possible in order to transport the objects from the loading position to the unloading position. The efficiency of the scaffold transport system is increased accordingly.

Furthermore, several unloading and loading positions can be provided in the rail system, with the corresponding carriage modules being able to be controlled by the system control to move to the corresponding positions. The unloading and loading positions can be defined by holding positions for the carriage module along the rail tracks that the rail system comprises. Alternatively, the slide modules can also be controlled manually to move to the appropriate positions.

The object of the invention is further achieved through the use of a scaffold transport system of the aforementioned type and/or the use of a method of the aforementioned type according to claim 7 in order to erect and/or dismantle a scaffold. The erection and dismantling of scaffolding is thus carried out efficiently and with a high degree of automation, which means that costs can be reduced accordingly.

The scaffolding transport system can consequently be used to deliver scaffolding material, for example scaffolding elements, fasteners and other building materials for scaffolding, to the required locations when erecting or dismantling the scaffolding. At the same time, the scaffold transport system can do this be used to expand or dismantle the corresponding scaffolding transport system, as this is modular.

The scaffolding transport system is expanded or dismantled in a simple manner if the scaffolding elements already include integrated rail sections, since the rail system is then expanded or dismantled at the same time as the scaffolding is erected or dismantled.

In figure 1 Figure 1 shows a scaffolding transport system 10 comprising a rail system 12 which in the embodiment shown is arranged on a scaffolding 14 comprising a plurality of levels A to H extending in a horizontal plane parallel to the ground. Accordingly, the scaffolding 14 has a floor A and seven further scaffolding levels B to H.

The scaffolding 14 corresponds to a conventional scaffolding, which consists of several scaffolding elements 16, for example tubes or bars, vertical posts, diagonals, running board coverings 18, which form the corresponding levels B to H, and connecting elements 19, via which the running board coverings 18 and/or the scaffolding elements 16 are connected to one another in order to form the scaffolding 14. The connecting elements 19 can be wedge connections.

In the embodiment shown, the rail system 12 comprises a plurality of horizontally running rail sections 20 and a plurality of vertically running rail sections 22 which are formed by modular rail elements 23 which are coupled to the scaffolding 14, in particular the scaffolding elements 16, as will be explained below. Accordingly, the rail elements 23 are designed separately from the scaffolding 14 .

In the embodiment shown, a horizontal rail section 20 is provided in the frame level B and another horizontal rail section 20 is provided in the frame level F, so that four frame levels B to F lie between the two horizontal rail sections.

The vertically running rail sections 22, however, are provided at intervals of two vertically running scaffolding elements 16, as shown in FIG figure 1 emerges. However, the distances can also be selected differently, depending on requirements.

The respective vertically running rail sections 22 and the horizontally running rail sections 20 are each coupled to one another, so that crossings 24 of the corresponding rail system 12 result, which will be discussed below.

Furthermore, two vertical rail sections and two horizontal rail sections, which connect the two vertical rail sections to one another, form a two-dimensional closed rail system area 26 which, in a frontal view of scaffolding 14, partially covers a plane of scaffolding 14 that extends in the horizontal and vertical directions extends. The vertical rail sections are each formed by four rail elements 23 , whereas the horizontal rail sections are each formed by two rail elements 23 .

In the embodiment shown, a plurality of rail system areas 26 connected to one another are provided, which are arranged adjacent to one another and are connected to one another. The connection of the adjacent rail system areas 26 takes place in that they share a horizontally running partial rail section or a vertically running partial rail section.

Total are in figure 1 four different rail system areas 26 are provided.

The rail sections 20, 22, in particular the rail elements 23, are all designed to be stationary, so that the rail system 12 is fixed.

In addition to the rail system 12, the scaffold transport system 10 comprises at least one carriage module 28, which is set up to move along the rail system 12, as will be explained below, in particular with reference to FIG Figures 4 to 7 .

For this purpose, the carriage module 28 has a coupling section 30, via which the carriage module 28 is captively and movably coupled to the rail system 12 during operation (see in particular Figures 4 to 6 ). In addition, the carriage module 28 includes a support section 32, via which the carriage module 28 can carry objects, as can be seen from FIG figure 1 emerges. For this is with the support portion 32 coupled a load handling unit 34, which is based on the below figures 6 and 7 is explained in more detail.

In figure 1 A total of four carriage modules 28 are shown that belong to the scaffold transport system 10 . Consequently, each rail system area 26 is assigned at least one carriage module 28 .

In general, a plurality of carriage modules 28 can be provided for each rail system area 26, resulting in higher clocking in a corresponding rail system area 26. This is explained in more detail below with reference to the control of the scaffold transport system 10 .

The carriage modules 28 can also be moved over several rail system areas 26, i.e. one carriage module 28 for several rail system areas 26.

In general, the horizontally running rail sections 20 as well as the vertically running rail sections 22 define a plurality of movement paths for the carriage modules 28 along which the carriage modules 28 can move.

In the Figures 2a to 2c a part of the rail system 12 is shown in more detail, namely a rail element 23. The rail element 23 shown is a vertically running rail element 36, which is shown in different views.

Such a vertically running rail element 36 can already form a vertically running rail section 22 in a simple embodiment of the scaffold transport system 10 . Usually, however, a plurality of vertically extending rail elements 36 are provided to form a vertically extending rail section 22, as shown in FIG figure 1 emerges.

The vertically extending rail member 36 is formed separately from the vertically extending frame member 16, as shown in FIG Figure 2a emerges. It is coupled to the vertically running framework element 16 via fastening means 38, in particular to a coupling section 40 attached to the framework element 16, for example to a so-called rosette. The Coupling section 40, in particular the rosette, can be welded to the framework element 16, that is to say fixed in terms of position.

The corresponding fastener 38 is in the Figure 2c clearly visible. It is evident from this that the fastening means 38 can be in the form of a clip or plug-in connection which is of modular design so that it can be coupled to the corresponding coupling section 40 quickly and easily.

The fastening means 38 comprises in particular a wedge-shaped fastening section which has a slot through which the fastening means 38 can be pushed onto the coupling section 40, in particular the rosette. A fastening mechanism may be provided in the fastening portion which automatically actuates to couple the fastener 38 to the coupling portion 40 when the fastening portion has been slid onto the coupling portion 40 via the slot. In this case, for example, a bolt is guided through a receiving area of the coupling section 40 in order to lock the fastening means 38 on the coupling section 40 . The receiving area is one of the corresponding openings of the coupling section 40, ie the rosette.

The fastening means 38 is, for example, a modular frame wedge connection.

How from the Figures 2a and 2b As shown in particular, the vertical rail member 36 includes a traversing portion 42 formed via regular apertures 44 in a surface 46 of the corresponding vertical rail member 36. As shown in FIG. The openings 44 are arranged periodically at a regular distance, cooperating with the coupling section 30 of the carriage module 28, as will be explained below.

In general, the vertically extending rail member 36 can be made from sheet metal that has been bent, for example by means of a (CNC) bending machine. The metal sheet may be steel sheet to provide the required rigidity. The thickness of the sheet metal can be between 2 mm and 4 mm, in particular 3 mm.

How from the Figures 2a to 2c As can be seen, the corresponding vertically extending rail element 36 has a substantially Ω-shape, with the upper, continuous section defining the traversing section 42 being flat so that the carriage module 28 can move along the traversing section 42 . In addition, the free ends are bent again compared to a real Ω shape, in particular twice, so that they point to the opening of the "Ω". Due to the shape of the rail element 36, high flexural rigidity is ensured with little use of material, so that the respective rail element 36 is light but resistant to bending.

As in particular from the Figure 2c As can be seen, the vertically running rail element 36 has a substantially continuous slot 50 on its rear side 48, via which the respective, modularly constructed fastening means 38 can be inserted and slid into the vertically running rail element 36. The respective fastening means 38 can thus be displaced along the slot 50 in order to be adapted to the position of the coupling sections 40 of the vertically running scaffolding elements 16 which are usually arranged in a fixed manner. This ensures a correspondingly simple installation of the rail system 12.

The fastening means 38 can be selected as a function of the scaffolding that has been erected, in particular the type of scaffolding, and can be correspondingly coupled to the vertically running rail element 36 . To do this, it is used and pushed to the appropriate position. Then it is fixed so that it is attached to the rail element 36 .

The positions of the fastening means 38 can then be fixed accordingly, via fixing means or fixing mechanisms, in order to prevent undesired relative movement.

The length of the vertical rail member 36 may be 0.5 m, 1 m, 1.5 m, 2 m, 2.5 m, 3 m, 4 m or more, with the corresponding length being related to the commonly used lengths of vertical rails Framework elements 16 is adapted, which are standardized. Accordingly, intermediate lengths or shorter vertically running rail elements 36 can also be provided.

In the Figures 3a and 3b a further rail element 23 used in the rail system 12 is shown, namely a horizontally running rail element 52 which is designed essentially in a manner analogous to the vertically running rail element 36 .

In the embodiment shown, the horizontally running rail element 52 differs only in the type of connection to the scaffolding 14, in particular the scaffolding elements 16. Fastening means 54 are also provided, via which the horizontally running rail element 52 is connected to the corresponding coupling sections 40, for example the rosettes , which is coupled to vertically extending scaffolding elements 16 .

In some embodiments, the fasteners 54 and the coupling portions 40 of the framework members 16 may be a butt joint.

The fastening means 54 for the horizontally running rail element 52 each protrude at an angle α from the corresponding coupling section 40, the angle α to the horizontally running scaffolding element 16, to which the horizontally running rail element 52 is to be arranged parallel, being between 10° and 90° , in particular about 45°.

In the embodiment shown, the horizontally running rail element 52 is shorter than the corresponding horizontally running frame element 16 .

Otherwise, the rail element 52 running horizontally, like the rail element 36 running vertically, essentially has an Ω-shape, a travel section 42 with regular openings 44 being provided on a surface 46 of the rail element 52 running horizontally. Likewise, the horizontally running rail element 52 has an essentially continuous slot 50 on its rear side 48, via which the position of the fastening means 54 can be adjusted.

This in figure 1 The scaffolding transport system 10 illustrated, in particular its rail system 12, shows how the individual rail elements 23 are arranged on the scaffolding 14, i.e. the vertically running rail elements 36 and the horizontally running rail elements 52.

In the Figures 4 and 5 1 is shown in detail how the carriage module 28 is arranged on a rail element 23, in particular a vertically extending rail element 36 (see FIG figure 4 ) and a horizontal rail element 52 (see figure 5 ).

As already explained, the carriage module 28 comprises a coupling section 30, which in the embodiment shown is formed by four separately designed gripping units 56, of which only two gripping units 56 are shown in the figures. The four gripping units 56 are arranged in pairs opposite each other on the carriage module 28, so that each carriage module 28 comprises two gripping units 56 which are arranged in the direction of movement during operation and two further gripping units 56 which are arranged perpendicular to the direction of movement.

During operation, the carriage module 28 is constantly coupled to the corresponding rail element 23 with at least one gripping unit 56, so that the carriage module 28 is arranged captively on the rail system 12. The corresponding gripping units 56 thereby ensure that the carriage module 28 is nevertheless movably arranged, since they only at least partially encompass the corresponding rail element 23 . The gripping units 56 have in particular a gripping section 58 corresponding to the Ω-shape of the rail elements 23, that is to say a clamp-like gripping.

The gripping section 58 engages, for example, in a depression in the essentially Ω-shaped rail elements 23, so that the carriage module 28 is guided securely.

The four gripping units 56 ensure that the carriage module 28 can, on the one hand, travel over the crossings 24 of the rail system 12 and, at the same time, can change direction at the corresponding crossing 24 .

In this respect, the four gripping units 56 form a gripping mechanism and a direction-changing mechanism 59, which are described below with reference to FIG figure 1 is explained.

From the figure 1 shows that the vertically running rail sections 22 are continuous, which means that the carriage module 28 can be moved without braking along a corresponding vertical rail section 22 since there are no interruptions.

If the carriage module 28 is to be moved in the horizontal direction over a vertically running rail section 22, the carriage module 28 encounters an interruption. Due to the paired design of the gripping units 56, it is ensured that gaps or interruptions can be traversed, so that the carriage module 28 can still be moved unbraked. The gap or interruption to be bridged depends on the size of the slide module 28, in particular the distance between the gripping units 56 of a pair.

The use of the direction changing mechanism 59 will be explained below. For example, a carriage module 28 moves along a vertically extending rail section 22 towards an intersection 24 at which the carriage module 28 is to change its direction of movement from vertical movement to horizontal movement.

The front gripping unit 56 in the direction of movement can be released so that the carriage module 28 is only coupled to the corresponding vertically running rail element 36 via the rear gripping unit 56 in the direction of movement. The carriage module 28 is then moved to the crossing 24 so that the two gripping units 56 provided for the vertical movement are assigned to different vertical rail elements 36 of the rail system 12 .

Alternatively, the carriage module 28 is driven onto the crossing 24 without releasing one of the two gripping units 56 since the corresponding interruption or gap can be traversed by the carriage module 28 .

In this position, in which the carriage module 28 is located on the crossing 24, the two gripping units 56 provided for the horizontal movement are also assigned to two different horizontally running rail elements 52. However, both gripping units 56 provided for the horizontal movement are still in the inactive state.

Depending on the further horizontal movement (left or right), at least one corresponding one is provided for the horizontal movement Gripping unit 56 is actuated to engage the corresponding horizontally extending rail element 52, whereby the carriage module 28 is temporarily coupled to both at least one horizontally extending rail element 52 and at least one vertically extending rail element 36.

All gripping units 56 provided for the vertical movement are then released, so that the carriage module 28 is only coupled to the rail system 12 via at least one gripping unit 56 provided for the horizontal movement. The carriage module 28 can then be moved in the horizontal direction along the rail element 52 running horizontally.

In general, it can be provided that the carriage module 28 is coupled to the corresponding rail element 23 during the movement via one or two gripping units 56 .

In addition to the gripping units 56, the respective coupling section 30 of a carriage module 28 includes a sliding unit 60, via which the carriage module 28 is moved along the rail elements 23.

The corresponding sliding unit 60 interacts with the openings 44 of the displacement section 42 (see FIG figures 2 and 3 ), wherein the sliding unit 60 comprises, for example, a profile roller or a profile wheel, the corresponding profile having projections corresponding to the openings 44, which engage in the opening 44 when the carriage module 28 is moved along the rail elements 23.

The sliding unit 60 can be coupled to a drive integrated in the carriage module 28, which drives the sliding unit 60, in particular the profile roller or the profile wheel. The drive is located in the housing of the carriage module 28, which is why it cannot be seen in the figures.

The gripping units 56 and the sliding unit 60 therefore together represent a gripping-sliding mechanism 62 of the carriage module 28. The coupling section 30 consequently comprises a direction-changing mechanism 59 and a gripping-sliding mechanism 62.

According to a particular embodiment, a common gripping/sliding mechanism 62 can be formed, so that the sliding function is integrated in the corresponding gripping units 56, for example.

In general, the rail elements 23 that form the vertically running rail sections 22 and the horizontally running rail sections 20 can be connected to one another at the crossings 24 . The carriage modules 28 then have a correspondingly designed gripping/sliding mechanism 62 which makes it possible for the carriage modules 28 to travel over such crossings 24 and change their direction of movement there.

The special gripping-sliding mechanism 62 can be implemented by a defined activation sequence of the gripping units 56 .

In the figure 6 1 is an exploded view of a carriage module 28 arranged on a vertically running rail element 36, to the carrying section 32 of which, shown schematically, a load handling unit 34 is coupled.

The support section 32 has a modular design, so that different load handling units 34 can be coupled to the support section 32 . For example, it is a clip or clamp connection, so that the corresponding load handling unit 34 is coupled to the carriage module 28, in particular its carrying section 32, by pressure.

The load handling unit 34 shown comprises a support frame 64 and a core 66 which is arranged in the support frame 64 and is suitable for receiving different objects. This is clear from the Figures 7a to 7f emerge, in which the structure of the load handling unit 34 is shown in more detail.

For example, from the Figures 7e and 7f shows that the core 66 can be pushed onto the corresponding support frame 64. Depending on the embodiment, this can be done from the left or the right side or from both sides.

Accordingly, the support frame 64 of the load handling unit 34 is coupled directly to the support portion 32 of the carriage module 28 in a modular fashion. In addition, the support frame 64 itself can also be of modular design, so that different cores 66 can be used in the support frame 64 .

The in the figures 7 The core 66 shown is designed in such a way that it can accommodate standard scaffolding elements 16 for scaffolding in order to produce a further element of the scaffolding 14 . The core 66 is intended to receive at least four horizontally extending frame members 16, two deck decks 18, and two vertically extending frame members 16, as shown. In general, however, the core 66 can accommodate more objects.

In addition, the core 66 includes a safety mechanism 68, via which the objects placed in the load-bearing unit 34, in particular the core 66, such as scaffolding elements 16, can be appropriately secured. This ensures that the objects to be transported cannot become detached from the carriage module 28 and fall down.

In the embodiment shown, the safety mechanism 68 is formed by a folding mechanism and holding elements 70 coupled thereto, which can be operated on the outer sides of the core 66 . About this, the holding elements 70 can be adjusted to be transferred to a receiving position in which the core 66 can be loaded; see in particular Figure 7b .

In general, a load handling unit 34 can be arranged on the carrying section 32 of the carriage module 28, with which people can also be transported. Accordingly, the correspondingly designed load handling unit 34 has a basket or the like with which people can be transported.

In figure 8 1 is shown an alternative embodiment of a scaffold transport system 10 according to the invention which is essentially that of FIG figure 1 is equivalent to.

This in figure 8 Scaffolding transport system 10 shown comprises at least one further horizontal rail section 20, which belongs to the figure 1 Shown horizontally extending rail sections 20 is substantially perpendicular, ie in a to the through figure 1 constructed level of the scaffold transport system 10 additional, third level.

The at least one further horizontal rail section 20 is connected to the other horizontal rail section 20 via a rail curve element 72 which extends over a corner of the scaffolding 14 .

As a result, the scaffolding transport system 10 and the rail system 12 are three-dimensional, since two two-dimensional rail systems, which are essentially perpendicular to one another, are coupled to one another via the curved rail element 72 . At the in figure 1 The rail system 12 shown is therefore a two-dimensional rail network. The correspondingly constructed rail networks each represent a rail plane that is spanned by the horizontal and vertical directions, which corresponds to the front of the framework 14 .

In the embodiment shown, both two-dimensional rail networks do not yet have any two-dimensionally closed rail system areas 26, since only one horizontally running rail section 20 is provided per rail network.

However, a further horizontally running rail section 20 can be installed on each of the upper scaffolding levels in order to form two-dimensionally closed rail system areas 26 so that rail system areas 26 of the rail system 12 that are adjacent across the corners are then coupled to one another via the rail curve element 72 . The two two-dimensional rail networks can consequently be connected to one another via the rail curve element 72 in order to form the three-dimensional rail system 12 .

How from the figure 8 As can be seen, in particular the arrows drawn in, it is possible for at least one carriage module 28 to move over both two-dimensional rail networks, so that the carriage module can also be moved around curves or corners of the scaffolding 14 . As a result, material can thus be transported over long distances in an automated manner, in particular over corners of a building.

Accordingly, only two workers are required to set up such scaffolding 14, as in figure 8 is shown, namely one at a loading position 74 and another at an unloading position 76 of the rail system 12. This applies analogously to the structure in FIG figure 1 .

The carriage module 28 is loaded or unloaded at the corresponding positions 74, 76, with the carriage module 28 being moved between the two positions 74, 76 along the rail system 12, in particular along the rail curve element 72.

in the in figure 8 In the embodiment shown, the rail curve element 72 is an outer curve element. in the in figure 9 In the illustration shown, a rail curve element 72 is shown which allows an inside curve.

It is generally possible that the rail system 12 and thus the scaffolding transport system 10 can also cover complex shapes of scaffolding 14 via the different rail curve elements 72, ie outer curve and inner curve element.

As can be seen from the figures, the scaffolding transport system 10 and the method explained can be used both for scaffolding erection and for scaffolding dismantling. Furthermore, the scaffolding transport system 10 and the method explained can be used to transport material, for example building material, or people, in particular when the scaffolding 14 has already been completed.

Due to the automated scaffold transport system 10, the objects are transported in an efficient manner, since the transport is automated. If several carriage modules 28 are used, a constant flow of material is also ensured, since material can be made available at a desired cycle rate despite long distances.

This provides an efficient scaffolding transport system 10 and a method with which scaffolding assembly and dismantling in particular is simplified and accelerated. At the same time, safety is increased because human errors are reduced to a minimum.

To control the scaffold transport system 10, in particular the movement of the individual carriage modules 28 (see figure 1 ), a system controller 78 is provided.

The individual carriage modules 28 are controlled via the system controller 78, with the system controller 78 being configured as a central unit that communicates with the carriage modules 28, or as a decentralized unit that includes a number of control modules that communicate with one another in order to jointly control the system controller 78 to train. In the decentralized variant, for example, the carriage modules 28 each include a control module, with the carriage modules 28 communicating with one another.

In the embodiment shown, a mixed form is provided, according to which the system controller 78 includes a central control unit 80 and the individual carriage modules 28 each include control modules 81, which all communicate with one another.

The central control unit 80 can be operated by the user to control the at least one carriage module 28 . For example, the central control unit 80 is a portable device worn by the user.

Several (central) control units 80 can also be provided, which are either assigned to a specific section of the rail system 12, i.e. the carriage modules 28 located there. In the case of several control units 80, it can also be provided that these have a hierarchy, so that a ( central) control unit 80 forms the main control unit.

• Aktualisieren der Position des Benutzers, also des Arbeiters, der die zentrale Steuereinheit 80 trägt,
• Senden von Stopp- bzw. Nothalt-Befehlen für das wenigstens eine Schlittenmodul 28,
• Pausieren/Wiederaufnahme der Ausführung bzw. Bewegung des wenigstens einen Schlittenmoduls 28, und/oder
• Manuelle oder halb-manuelle Fahrbefehle an das wenigstens eine Schlittenmodul 28 senden.

The following functions of the scaffold transport system 10, among others, can easily be implemented via the at least one (portable) central control unit 80:

• Updating the position of the user, i.e. the worker carrying the central control unit 80,
• Sending stop or emergency stop commands for the at least one carriage module 28,
• Pausing/resuming the execution or movement of the at least one carriage module 28, and/or
• Send manual or semi-manual travel commands to the at least one carriage module 28.

In this respect, the user can actively intervene in the movement sequences of the at least one carriage module 28 via the (portable) central control unit 80 or his position is transmitted in order to prevent a collision, as already explained above.

In general, the system controller 78 can be provided with artificial intelligence or machine learning techniques that enable the control of the carriage modules 28 to become more efficient and/or autonomous during the operation of the scaffold transport system 10 .

Furthermore, the system controller 78 can take into account different security protocols or security rules when controlling the individual carriage modules 28 in order to comply with desired security standards. In particular, the system controller 78 takes into account that people are not endangered, so that in principle a sufficiently large distance is maintained between a moving carriage module 28 and a person.

The system controller 78 can access sensor data that is recorded by sensors 82 that are carried, for example, on the individual carriage modules 28, the rail system 12, in particular crossings 24, and/or the people on site. Accordingly, it is possible, among other things, to automatically detect the position of the workers and/or the carriage modules 28 and to take it into account when controlling the movement of the carriage modules 28, so that neither persons are endangered nor carriage modules 28 collide with one another.

In general, the scaffolding 14 can be erected in that the first two to three scaffolding levels or scaffolding bays are still conventionally assembled, with the horizontally running rail section 20 being installed on the first scaffolding level.

Based on this, material, in particular framework elements 16 and/or rail elements 23, can be transported to the desired places of use by means of the carriage module 28 in order to expand the rail system 12 and/or the framework 14. The rail system 12 can be due to the expand modular structure of the individual rail elements 23 in the desired manner.

If a two-dimensional closed rail system area 26 has been created, a continuous flow of material can be provided, for example by operating several slide modules 28 simultaneously via the system controller 78 (see figure 1 ). As a result, the efficiency can be increased accordingly.

Due to the sensors used, worn by the workers located on the scaffolding 14, corresponding unloading positions can be defined which correspond to the locations where the workers are located. This ensures that the material is delivered to the desired place of use.

In order to find the best possible movement path, the system controller 78 can have recorded the rail system 12 in terms of control technology, for example as a two-dimensional or three-dimensional map. The intersections 24 can represent reference or node points for the system controller 78 .

In general, the scaffold transport system 10 can be operated manually via a control unit, in a partially automated or fully automated manner, with the degree of automation depending on the wishes of the operator of the scaffold transport system 10 .

For example, the speed of the slide modules 28 can be set in the partially automated control, with a maximum speed of up to 60 m/min being provided in fully automated operation. In the case of the partially automated control, it can also be provided that the workers enter manually whether the corresponding carriage module 28 has been unloaded or loaded.

In general, the carriage modules 28 are designed to transport at least twice their own weight as a load, for example a load of at least approx. 60 kg with an own weight of 30 kg, with the carriage modules 28 usually being able to transport loads of more than 100 kg.

The power supply of the individual carriage modules 28 is ensured by batteries, for example Li-ion batteries, which can be designed as accumulators. The system controller 78 can monitor the battery status of the sled modules 28 and command them to be automatically moved to a charge collection point if the charge status is critical.

The corresponding carriage module 28 can then be replaced by an already fully loaded carriage module 28, which is possible since the carriage modules 28 are modular and can therefore be used universally. Charging a discharged sled module 28 takes approximately 1 to 5 hours.

As an alternative to the illustrated embodiments with the separately formed rail elements 23, framework elements 16 can also be provided which already comprise the respective rail sections 20, 22 in an integral manner. Thus, the track system 12 is implemented at the same time as the scaffold 14.

the inside figure 10 The section of the scaffold transport system 10 shown shows a changing station 84 at which a carriage module 28 can be reloaded by a new load handling unit 34 being coupled to the carrying section 32 of the carriage module 28 .

The new load handling unit 34 can already be preloaded in the changing station 84 so that the (empty) load handling unit 34 brought back by the carriage module 28 is replaced by the new (loaded) load handling unit 34 . In this way, the efficiency can be correspondingly increased, since the carriage module 28 is merely decoupled from the old load-carrying unit 34 and coupled to the new load-carrying unit 34 .

For this purpose, the changing station 84 can include a changing platform 86 so that the load handling unit 34 is at a suitable height for the operator.

In this respect, there is at least one loading position 74 at the changing station 84.

The changing station 84 can generally be used with the scaffold transport system 10 .

For example, the scaffold transport system 10 includes a plurality of changing stations 84, for example an upper changing station 84 for unloading and a lower changing station 84 for loading the respective carriage module 28. This can increase efficiency even further, since no time is lost due to loading and unloading.

In figure 11 a further scaffold transport system 10 not according to the invention is shown, which only has a vertically running rail section 22, in particular consists of this. The carriage module 28 accordingly moves along the vertically running rail section 22 in order to transport building material or the like from a lower level, in particular the ground, to a higher level of the scaffolding 14 .

The carriage module 28 can be designed in a manner analogous to the previous embodiments.
