Description

The invention relates to a transport system for several assembly elements to be assembled, in particular in a row, in particular fire protection and ventilation ducts, pipelines and cable duct elements, for transporting the assembly elements to a wall or ceiling surface, comprising a lifting device with which the assembly elements can be lifted to their assembly location on the ceiling surface, comprising at least one flat transport element on which the assembly elements can be placed, and at least one belt element, which is arranged on the transport element and with which it can be suspended, the lifting device being movable in a vertical direction is.

The D1 ( DE 10 2017 121 603 A1 ) discloses a conveyor and transport system for tunnel structures. The running rails of the two-rail hanging railway, which are arranged in parallel, are connected to one another via cross sleepers and suspended from the ridge of the tunnel structure. Carrying carriages guided by running gears are suspended from the rail elements. The trolleys can have devices for raising and lowering the wing.

D2 (WO 2021/003 526 A1) discloses a suspended, single-track rail system for transporting loads in mines. Several upper trolleys, which hold a rail, are suspended from anchor chains that are fixed in the roof of the mine. In turn, lower chassis are attached to this rail, which can accommodate transport devices.

The D3 ( DE 102 42 574 A1 ) discloses a method of making a tunnel and a monorail. A suspension device for a rail is injected with concrete into the outer shell of the tunnel. Vehicles are suspended from the single-track rail.

The D4 ( DE 20 33 514 A ) discloses a transport system for prefabricated walls. The upper edge of a wall is provided with rollers so that they can be moved with belt ropes hanging on a rail.

The retrofitting of fire protection ducts in halls with high ceilings is particularly difficult if the hall is already equipped with machines or other infrastructure. The fire protection ducts are usually composed of individual elements. During assembly, the elements are transported individually to the ceiling surface and assembled there consecutively, thus forming a route. For transporting the duct elements to the ceiling surface, hitherto lift trucks or forklifts have been used which stand on the floor and can be extended or retracted in a vertical direction. However, this system only works if the floor directly below where the fire protection duct will later run is freely accessible. If, for example, there is a system or machine (e.g. in a factory building), installation directly above this system is only possible with a great deal of effort and several workers.

The object of the present invention is to provide a transport system with which fire protection duct elements or other assembly elements can be transported quickly and easily to a ceiling surface without damaging the ceiling surface unnecessarily and the transport system can also be used when there is limited or difficult space and/or other trades are in the transport route and/or the floor directly below the installation site of the assembly elements is not freely accessible or there is an opening in the floor.

This object is achieved by a transport system for several assembly elements, in particular fire protection and ventilation ducts, pipelines and cable duct elements to be assembled in a row, for transporting the assembly elements to a wall or ceiling surface, comprising a lifting device with which the assembly elements can be lifted to their assembly site on the ceiling surface, comprising at least one flat transport element on which the assembly elements can be placed, and at least one belt element, which is arranged on the transport element and with which it can be suspended, the lifting device moving in a vertical direction is cash. The invention is characterized in that the transport system further comprises a rail device, which has at least one rail element, which is aligned parallel to the row of assembly elements to be installed, and has at least two fastening units, with which the rail element can be detachably fastened to the ceiling surface, the rail element being displaceable along the longitudinal axis of the rail element in a displacement direction relative to the fastening units, and the lifting device on the belt element also has an anchoring element, with which the lifting device can be fastened to the rail element, with the lifting device being fastened to the rail element in the fully raised state the mounting element resting on the lifting device is arranged between the two rail elements.

The mounting elements can be fire protection, ventilation or cable duct elements, or also pipes, or other infrastructure elements. However, it is also conceivable to use the transport system for any other element that has to be transported for mounting on a ceiling surface.

The lifting device is preferably designed as a device with which the assembly elements can be transported vertically. The transport element can preferably be used to lift loads of up to 2500 kg, but at least 25 kg. The entire transport system is preferably designed for transporting these loads. However, it is also conceivable that the lifting device can also be used to transport the assembly elements in a horizontal direction. The transport element of the lifting device is preferably designed as a plate or a box that is open at the top. The horizontal extent of the transport element can preferably be pulled out and/or pushed together in order to be adaptable to mounting elements of different sizes. Assembly elements with an extent of up to 0.80 m x 12.0 m can preferably be transported with the transport system according to the invention, particularly preferably with an extent of 1.0 m x 3.0 m. Larger assembly elements can thus be transported with the transport system according to the invention than with a lift truck, for example.

Furthermore, the transport element, preferably in the lowered state, can be used as a work table for the pre-assembly of the assembly elements. The lifting device is preferably already arranged on the rail device. For example, sections of pipes or ducts to be assembled parallel to one another can be prepared next to one another to form an assembly element and then transported to the ceiling surface in this state. Several assembly elements can also be transported simultaneously with the transport element.

The assembly elements can be placed on the transport element or, in the case of a box that is open at the top, can be placed in the transport element. Furthermore, it is conceivable that the transport element is designed as a closed box, which can preferably be opened on one of its outer surfaces. For example, smaller assembly elements can then be placed in the transport element, while larger assembly elements can be placed on the transport element. It is also conceivable that a drive element for driving the lifting device is arranged inside the box, so that the transport element can be pulled up by itself on the belt elements.

Four belt elements are preferably arranged on the transport element. The belt element is preferably designed as a rope, belt, toothed belt or band. The belt element is preferably made of thermoplastic polyurethane (PUR), a textile fabric, Kevlar or nylon. The belt element can preferably be loaded with loads of up to 2500 kg.

In a preferred embodiment, the transport member is a rectangular plate or box with the four strap members located near the four upturned corners. An anchoring element is arranged at the free end of each belt element. The belt element is preferably clamped in the anchoring element. The anchoring element is preferably screwed to the rail element or suspended in the rail element so that it can move in the direction of displacement. Furthermore, it is also conceivable that the anchoring element is designed as a hook or can be hung on the rail element with a tongue and groove system.

The rail element is designed as an elongate element which has a greater extent in its longitudinal direction than in its cross section perpendicular to this longitudinal direction. The rail element is preferably made of metal, in particular aluminum. The rail element can be fastened to the ceiling surface with the fastening units.

The rail system preferably has two rail elements. The fastening units are mounted in two rows along the planned course of the row of mounting elements to be mounted. A row is preferably arranged on the longitudinal sides of the planned course of the row of assembly elements to be assembled. The two rows are preferably at a distance from one another which is slightly greater than the width of the mounting elements, so that a mounting element can be arranged between the rows. The rail elements can be fastened to the fastening units.

When fastened to the fastening units, the rail elements can be displaced relative to the fastening units along the row of fastening units in the displacement direction thus defined. The rail elements are thus preferably aligned parallel to the row of mounting elements to be assembled. Two belt elements can preferably be fastened to each rail element, so that the transport element is arranged parallel to the ceiling surface and under the installation site of the installation elements with the aid of the cable and rail elements.

The mounting location is the location on the ceiling surface at which a mounting element is currently being mounted or is to be mounted next. For example, with fire protection ducts one mounting element after the other is first transported to the ceiling surface and then mounted at the end of a row of already mounted mounting elements, the mounting location changes after each mounting of a mounting element in the direction of the displacement. The assembly location shifts horizontally by the length of an assembly element in the direction of the assembly elements of the planned assembly element row that are still to be assembled in the direction of displacement. The lifting device can now follow this displacement by horizontal displacement in the direction of displacement with the aid of the rail system. The lifting device can also be lowered and loaded at a location which is not immediately below the installation site. After loading, the lifting device can then be pulled up in a vertical direction and, in the raised state, can be displaced in the direction of displacement with the aid of the rail system until the assembly site is reached. Furthermore, it is also conceivable that the assembly system according to the invention can be used for the disassembly or replacement of assembly elements.

According to at least one further embodiment, the transport system also has a frame device, which comprises a flat, horizontally arranged base element, at least two flat, vertically arranged side elements, which are each arranged on an edge of the base element, and at least three wheel elements, which are arranged underneath the base element on the latter and with which the frame device can be moved on a floor, the lifting device with its anchoring elements being able to be fastened to the upper edges of the side elements.

The base element is preferably designed as a plate or grid. The side elements are preferably designed with two rods each arranged at a corner of the base element, the rods of a side element being connected with crossed struts. Four wheel elements are preferably arranged on the underside of the base element. The wheel elements are preferably designed as wheels or rollers. The frame device thus preferably forms a rollable carriage.

The height of the side elements can be freely selected and adapted to the desired application. The anchoring elements of the lifting device can preferably be fastened to the upper end of the rods of the side elements. The rods preferably each have a guide element which encloses the rods along their circumference and can be displaced in a vertical direction on the rods. The transport element of the lifting device can preferably be hooked into the guide elements, so that the transport element can be guided securely in a vertical direction on the frame device. In this state, the lifting device can be raised and lowered in the frame device.

The frame device can preferably be used to transport the assembly elements from, for example, a raised loading area of a transport vehicle to the vicinity of the assembly site with the aid of the lifting device suspended from the frame device. It is also conceivable to transport the assembly elements with the frame device directly to the assembly site, for example if the floor is freely accessible directly below the assembly site. The assembly elements can be displaced relative to the ground with the aid of the frame device and the wheel elements and can be raised and lowered in the vertical direction with the aid of the lifting device.

Even when the lifting device is arranged on the frame element, the transport element can be used, preferably in the lowered state, as a work table for the pre-assembly of the assembly elements.

According to at least one further embodiment, the fastening units of the rail device can be fastened to the ceiling surface along a straight line and at a distance smaller than the length of the rail element and each have at least one roller element, the rail element being displaceable relative to the roller element in the displacement direction parallel to the ceiling surface.

According to at least one further embodiment, the rail element is designed as a hollow profile with a recess designed to complement the roller element, with the rail element enclosing the roller element with its wall delimiting the recess and the wall also having a recess in which a connecting unit can be guided, which connects the roller element to a fastening element, which is arranged on the ceiling surface.

The fastening element is preferably designed as an angle, one leg surface of which is arranged on the ceiling surface and the other leg of which is arranged on the connecting unit. The connecting unit is preferably oriented vertically, arranged with its upper end on the fastening unit and has a roller element at its lower end. The connection unit can preferably be exchanged for a connection unit with a different length in its vertical direction. By using longer When the lifting device is in the fully raised state, the connection units have the mounting element at a greater distance from the ceiling surface, so that obstacles on the ceiling surface, for example existing pipelines or supports, can be overcome.

The roller element is preferably designed as a double roller, with one roller being arranged on each side of the connection unit. Both rollers have a common axis of rotation, which is preferably arranged parallel to the ceiling surface and perpendicular to the direction of displacement. The rollers are preferably made of a plastic or a plastic mixture, so that they can be rolled in the rail element with particularly little friction. The rail element is preferably designed as a hollow profile. The rail element can preferably be slipped onto the roller elements in the direction of displacement, so that the roller elements are arranged in the enclosed space of the hollow profile, also referred to as a recess. The roller elements run in the enclosed space of the hollow profile. The rail element can thus be displaced relative to the fastening units by a rolling movement of the roller elements on the inner surface of the rail element in the direction of displacement.

The fastening units of a row are preferably fastened to the ceiling surface at a distance from one another that is smaller than the length of the rail element. The rail element is always guided by at least two fastening units parallel to the ceiling surface and in the direction of displacement. Before a roller element is guided out of one end of the rail element when the rail element is displaced, the other end of the rail element always reaches a further fastening unit and thus a further roller element.

According to at least one further embodiment, the fastening units of the rail device can be fastened in a hole in the ceiling surface, which can be used for fastening the assembly elements.

A first assembly element is preferably transported to its assembly site with the transport system according to the invention and is temporarily fastened there to the ceiling surface. Fastening units are preferably not fastened in all bores of the ceiling surface. This is made possible in particular by the fact that fewer attachment points are required for the secure attachment of the rail device than for the attachment of the assembly elements. Thus, even when the rail device is arranged on the ceiling surface, there are still free bores in which the mounting elements can be fastened. Following the attachment of the first assembly element, the second assembly element is transported to its assembly site, which is offset in the direction of displacement to the first assembly site, but is directly adjacent to the first assembly site. The second mounting element is also attached first. From this point on, the transport system no longer has to be moved back to the first installation location in the opposite direction to the displacement direction. The fastening units for the rail elements at the first installation location are therefore no longer required and can be removed.

The first mounting element is now preferably finally fastened in the now free bores of the removed fastening units at the first mounting location. In this way, all mounting elements of the row of mounting elements can be fastened provisionally and then finally, one after the other, with the final fastening preferably taking place in the bores of the remote fastening units. The mounting element is preferably fastened with screws and dowels in the holes in the ceiling surface, but any other fastening method is also conceivable here, for example using nails, adhesive or other fastening methods known to those skilled in the art.

According to at least one further embodiment, the transport element has at least one traverse element, which is arranged on the upper side of the transport element, wherein it has at least one recess at the end points of its longitudinal extent, in which a belt element on the traverse element can be guided.

In its longitudinal extension, the traverse element is preferably arranged transversely to the direction of displacement. The belt element, which is guided at one end of the traverse element, is therefore preferably connected to one of the two rail elements of the rail device and the other belt element, which is guided from the other end of the traverse element, is connected to the other of the two rail elements.

The transport element preferably has two traverse elements. The two traverse elements are preferably arranged parallel to one another and transversely to the direction of displacement on the transport element. The two traverse elements are preferably arranged on the upper side of the transport element. The two traverse elements are preferably arranged on the front and rear edges of the upper side of the transport element, viewed in the direction of displacement. It is also conceivable that the transport element has more than two traverse elements. In this case, all traverse elements are preferably arranged parallel and transverse to the direction of displacement. The additional traverse elements are preferably arranged between the two traverse elements on the front and rear edges of the upper side of the transport element. Two belt elements are preferably arranged on each cross member, so that if the lifting device has more than two cross members, it also has twice as many additional belt elements as additional cross members.

Preferably, the traverse element can be pulled out and pushed together, so that the length of the traverse element can be adapted to the width of the mounting elements and thus also to the distance between the two rows of fastening units. The traverse element preferably has a recess at its end, in which the belt element is guided. Thus, viewed from the rail element, the belt element preferably enters the traverse element from above through an entry opening. It is conceivable that there is an outlet opening on the underside of the traverse element, from which the belt element emerges and from there it can be guided onto the underside of the transport element. It is also conceivable that the outlet opening of the traverse element is connected directly to the interior of the transport element designed as a box. In this case, the belt element preferably emerges from the outlet opening of the traverse element and is then arranged directly in the interior of the transport element.

According to at least one further embodiment, the lifting device comprises a drive element which is arranged on the underside of the transport element and with which the belt element can be shortened and lengthened, the transport element being able to be raised and lowered in a vertical direction by shortening or lengthening the belt element.

All belt elements are preferably guided to the drive element on the underside of the transport element. The drive element preferably comprises at least one coil element and at least one motor element, with which the coil element can be driven. A belt element can preferably be wound up and unwound with the coil element. The drive element preferably has the same number of coil elements as the lifting device has belt elements. However, it is also conceivable that several belt elements can be wound up and unwound on a common coil element. Each coil element preferably has its own motor element, so that each of the coil elements can be controlled individually with the aid of a control element.

By winding the strap member onto the spool member, the strap member is shortened and the hoist is lifted in a vertical direction. By unwinding the strap member from the spool member, the strap member is lengthened and the hoist is lowered in a vertical direction. All motor elements are preferably controlled with the aid of a control element, so that the transport element is raised and lowered evenly. It is also conceivable that the control element has a sensor element with which the position of the transport element in space can be measured, so that the motor elements and coil elements can be controlled in a targeted manner and independently of one another with the help of this sensor information, so that, for example, an inclined position of the transport element in space can be compensated for by targeted lengthening and/or shortening of individual belt elements.

• - Transport von zumindest einem Montageelement an den Montageort durch Auflegen von zumindest einem Montageelement auf das Transportelement und Bewegung der Hebevorrichtung in der vertikalen Richtung und/oder horizontale Bewegung der Hebevorrichtung durch Verschieben des Schienenelements in Verschieberichtung auf den Rollenelementen;
• - Montage des Montageelements am Montageort,

wobei die letzten beiden Schritte beliebig oft wiederholbar sind bis sämtliche Montageelemente am Montageort montiert sind.The object is also achieved by a method for the assembly, in particular the assembly on a ceiling surface, of a continuous row of assembly elements, in particular fire protection, ventilation and cable duct elements, with a transport system comprising a lifting device which has at least one flat transport element, at least one belt element and at least one anchoring element and with which the assembly elements can be lifted in a vertical direction, and a rail device which has at least one fastening unit, comprising at least one roller element and at least one rail element which is mounted on the roller elements in a displacement direction -is slidably slidable, wherein in the fully raised state the mounting element is arranged resting on the lifting device between the two rail elements, comprising the steps:

• - Fastening at least two fastening units along a straight line at the installation site distributed over the entire length of the row of mounting elements to be mounted on a ceiling surface at a distance from one another which is smaller than the length of the rail element in its direction of displacement;
• - Fastening the lifting device to the rail device by fastening the anchoring elements of the lifting device to the rail element and pushing the rail element onto the roller elements of the fastening units in the direction of displacement;
• - Transport of at least one assembly element to the assembly site by placing at least one assembly element on the transport element and movement of Hebevor direction in the vertical direction and/or horizontal movement of the lifting device by sliding the rail element in the direction of sliding on the roller elements;
• - assembly of the assembly element at the assembly site,

The last two steps can be repeated as often as you like until all assembly elements have been assembled at the assembly site.

In a first step, the fastening units are preferably fastened in two rows to the ceiling surface, as described above. The two rows are preferably at a distance from one another which is greater than the width of the mounting elements. Within a row, the fastening units are preferably fastened at a distance from one another that is smaller than the length of the rail element in the direction of displacement. The rows are arranged parallel to each other and parallel to the direction of displacement.

In the second step, the lifting device is attached to the rail device. For this purpose, preferably all anchoring elements of the lifting device are fastened to the preferably two rail elements of the rail device and the rail elements are pushed onto the roller elements. One rail element is preferably pushed onto at least two roller elements of at least two fastening units in a row of fastening units and the other rail element is preferably pushed onto at least two roller elements of at least two fastening units in the other row of fastening units.

The transport system is now ready for use and the transport of the assembly elements to their respective assembly site can begin.

For this purpose, in a third step, the lifting device is moved vertically and with the aid of the rail device horizontally to a loading location. At least one assembly element is placed on the transport element at the loading location. The lifting device is now moved vertically and with the help of the rail device horizontally to the installation site. An obstacle, for example a machine or system standing on the ground, or a shaft opening can be overcome, for example by a first vertical movement followed by a horizontal movement, since the transport element can be guided over the obstacle with the help of the lifting device and the rail device.

In the fourth step, the assembly element is attached or assembled at the assembly site.

Steps three and four can now be repeated as often as further assembly elements are to be assembled.

According to at least one further embodiment, after a mounting element has been transported to its mounting location, at least one of the mounting points that were previously used for mounting the mounting units is used to mount the mounting element.

It is conceivable that this step is carried out instead of the fourth step of the method described above. It is also conceivable that this step is carried out in addition to the fourth method step and that only a provisional attachment of the assembly element takes place at the assembly site in the fourth method step.

According to at least one further embodiment, after the fastening units have been fastened to the ceiling surface, the lifting device with its anchoring elements is first fastened to a frame device, which has at least three wheel elements with which the frame device can be moved in a horizontal plane relative to the floor, and then the mounting elements are transported on a first part of the transport route to the installation site using the lifting device, which is arranged on the frame device, and only then are the anchoring elements of the lifting device fastened to the rail element and the rail elements pushed onto the roller elements of the fastening units.

In this way, part of the transport path for the assembly elements can first be overcome with the lifting device arranged on the frame device. For example, unloading the assembly elements from a truck or other means of transport, for example. With the help of the frame device, assembly elements can be transported from one room to another room or from one building to another building with the transport system according to the invention, since a continuous ceiling surface is preferably present for the use of the rail system.

For dismantling, the lifting device is lowered from the frame device until the transport element rests on the base element and the belt elements are no longer loaded. The anchoring elements can now be detached from the rods of the side elements and fastened to the preferably two rail elements. The further method corresponds from now on to the second, third and fourth method step of the method according to the invention described above.

According to at least one further embodiment, the assembly elements are transported to the installation site with the lifting device arranged on the frame device by moving the frame device horizontally on the floor and moving the lifting device vertically, and the step of attaching the fastening units to the ceiling surface is omitted.

It is therefore also conceivable, for example in rooms with low ceiling heights or if there is no obstacle on the floor below the installation site over which the installation elements have to be transported, that no conversion of the lifting device from the frame device to the rail device is necessary. It is therefore conceivable that the assembly elements are transported to the assembly site exclusively with the lifting device arranged on the frame device.

1 shows the transport system 1 according to the invention. In this figure, the assembly elements 2 are assembled in a row of assembly elements, which runs from right to left, i.e. in the displacement direction S, on the ceiling surface 3. The assembly element 2 is placed on the transport element 5 of the lifting device 4 for transport to the ceiling surface 3. This loading takes place preferably on the left edge of 1 instead of. For this purpose, the lifting device 4 is moved to the left in the direction of displacement S with the aid of the rail device 9 . The drive element 7 arranged in the embodiment shown in the interior of the transport element 5 (therefore in 1 (not visible) shortens or lengthens the belt elements 6 and thus raises or lowers the transport element 5 in a vertical direction V. In the loaded state, the lifting device 4 is now raised and the assembly element 2 is transported by moving the lifting device 4 with the aid of the rail device 9 to the right, counter to the direction of displacement S, to the assembly site.

In this embodiment, the transport element has two traverse elements 24 which are arranged transversely to the displacement direction S on the upper side of the transport element 5 . The traverse elements 24 can be pulled out and/or pushed together, so that the width of the transport element can be adjusted transversely to the direction of displacement S to the width of the assembly elements.

The belt elements 6 are fastened to the two rail elements 10 of the rail device 9 with the aid of the anchoring elements 12 . In this embodiment, the anchoring elements are designed as rods that each connect two belt elements and can be fastened to the rail element 10 . The mounting elements 2 are mounted between the rail elements 10 and the rail elements are then moved in the displacement direction S. The finished row of assembly elements runs parallel to the direction of displacement S. The rail elements 10 are fastened to the ceiling surface 3 with the aid of fastening units 11 and can be displaced in the direction of displacement S in relation to the fastening units 11 .

The mounting elements already mounted are fastened to the ceiling surface 25 with the aid of a fastening rod element 25 .

2 shows a detailed view of the lifting device 4 and the rail device 9. In this embodiment, the anchoring elements 12 are designed as individual elements. In this embodiment, each belt element is thus attached individually to the rail element. The fastening elements 11 are fastened in bores on the ceiling surface 3, in which the fastening rod element 25 can also be fastened. The rail element 10 can be displaced in the displacement direction S relative to the fastening units 11 . In the embodiment shown here, the lifting device has a drive element 7 which is arranged on the underside of the transport element 5 . The drive element 7 is connected to a control element 8 . The lifting device can be raised and/or lowered with the control element 8 . The connection of the control element 8 with the drive element 7 is both a physical connection, for example wise via a cable, or as a radio, WLAN, Bluetooth or IR connection. In the embodiment shown here, the transport element 5 is designed as a box that is open at the top. The traverse elements 24 are arranged on the upper side of the side elements of the transport element 5, which are aligned transversely to the direction of displacement S. In this embodiment, the mounting element 2 rests only on the traverse elements. In the transport element, which is open at the top, assembly aids and/or also the fastening rod elements 25 and/or small parts such as screws and dowels and/or tools can be transported, for example.

In the fully raised state, the mounting element rests on the lifting device and is arranged between the two rail elements.

3a shows a detailed representation of the rail device 9. The fastening units 11 each comprise a fastening element 23, which rests flat on its upper side on the ceiling surface 3 and can be fastened to this. At the lower end of the fastening element 23, this has two extensions 26 arranged parallel to one another and perpendicular to the ceiling surface. The connecting element 22 is arranged between these extensions 26 . The connecting element 22 is fastened to the extensions 26 by a plug-in axle 27 which is arranged parallel to the ceiling surface and perpendicular to the direction of displacement in its longitudinal extension and can be inserted through both the extensions 26 and the connecting element 22 . Four roller elements 18 are arranged at the lower end of the connecting element 22 . Viewed in the direction of displacement, two roller elements 18 are arranged on the left side and two roller elements 18 on the right side of the connecting element 22 . The roller elements 18 on one side of the connecting element 22 are offset from one another in the direction of displacement and are therefore arranged next to one another, but at the same height.

The rail element 10 can be slid onto the roller elements 18 of the fastening unit 11 in the direction of displacement or counter to it. The rail element 10 is in the form of a hollow profile with a wall 20 enclosing a recess 19 . The wall 20 has a recess 21 on the upper side of the rail element 10 . This recess 21 is somewhat wider in its extension transversely to the displacement direction S than the connecting element 22 in this direction, so that the connecting element 22 can be arranged in the recess 21 .

3b shows a detailed view in the direction of displacement S of the rail system. The rail element 10 is shown here in the state in which it has been pushed onto the roller elements 18 . The roller elements 18 and the connecting element 22 arranged between them are arranged in the recess 19 of the rail element 10 . The roller elements 18 and the connecting element 22 arranged between them fill the recess 19 almost completely.

A guide element 27 , similar to the hollow profile of the rail element 10 , is arranged on the underside of the rail element 10 . The anchoring elements 12 can be fastened to this guide element 27 . In another embodiment, the anchoring elements 12 can be hooked into the guide element 27 . It is conceivable that the anchoring elements 12 in the guide element 27 can be displaced in the direction of displacement S or counter to it.

4 shows an overview of the lifting and frame device 4, 13 of the transport system 1. The transport of the assembly elements 2 to the ceiling surface 3 with the help of the frame device works very similarly to the variant with the rail device 9. However, the displacement in the displacement direction S takes place with the aid of the frame device 13, which can be rolled over the floor 17 with the wheel elements 16 and can therefore be displaced in the displacement direction S. The frame device 13 has a base element 14, which is arranged parallel to the floor 17 and to the ceiling surface 3, and side elements 15, which are arranged parallel to the displacement direction S. The anchoring elements 12 are arranged at the upper end of the side elements 15 . Thus, the lifting device 4 is arranged between the side members 15 and can be moved up and down in a vertical direction V between them. The transport element can preferably be raised to the height of the upper end of the side elements 15 at most. The assembly element 2 can thus be placed on the transport element 5 and can be lifted in a vertical direction V with the aid of the lifting device. The width of the frame device 13 is preferably adjustable transversely to the direction of displacement S, so that it can be adapted to mounting elements of different widths. The height of the side elements 15 is preferably also adjustable, so that they can be adapted to the height of the assembly site above the floor 17 and the assembly element can preferably be lifted up to the assembly site.

5 shows a detailed representation of the frame device 13 with the lifting device 4 arranged thereon. At both ends of the square rod member 28 is a wheel member 16 is attached arranges. The two square bar elements are connected to two cross bar elements 29 . The crossbar elements 29 are arranged transversely to the displacement direction S and at a right angle to the square bar elements 28 .

On the upper side of the square bar elements 28 a side element 15 is arranged in each case. The side element is arranged parallel to the vertical direction V and to the direction of displacement S in its planar extent. The two-dimensional extension of the side element is delimited in the direction of displacement S by two square rod elements 31 . These are aligned vertically and are perpendicular to the square rod elements 28 of the base element 14 and are stabilized at an angle 30 .

The two square rod elements 31 of the side elements 15 are aligned parallel to one another and are connected to one another by strut elements 32 . The strut elements 32 are arranged parallel to the displacement direction S. At the upper end of the two square bar elements 31 of a side element 13 a top strut element 33 is arranged parallel to the other strut elements 32 .

The uppermost strut element 33 is arranged on the face of the square rod elements 31 pointing upwards. The top strut element 33 has a length greater than the distance between the two square bar elements 31, so that the top strut element protrudes beyond the square bar elements 31 in the displacement direction S. The anchoring elements 12 of the lifting device 4 can be attached to the protruding underside of the uppermost strut element 33 . The belt elements thus run parallel and in the immediate vicinity of the square bar elements 31.

In this embodiment, the traverse elements 24 include the square bar elements 31, so that the transport element 5 is guided securely in the vertical V direction. In this embodiment, the traverse elements 24 can also be pulled out and/or pushed together, so that the width of the lifting device 4 can be adapted to the width of the mounting elements 2 to the same extent as the width of the frame device 13 .

6 shows an example of the transport system 1 according to the invention with the lifting device 4 and the rail device 9 when used for ceiling mounting of fire protection ducts 2 over a ground obstacle 34 and a shaft 35, which is located in the ground.
