[0001] DEVICE AND METHOD FOR MOVING AN INFRASTRUCTURE COMPONENT, IN PARTICULAR A TRACK SUPPORT PLATE

[0002] The invention relates to a device for moving an infrastructure component, in particular a track support slab, prepositioned on a ground into a target arrangement. Furthermore, the invention relates to a combination comprising at least one such device. The invention also relates to a system comprising at least one such device. Furthermore, the invention relates to a method for moving an infrastructure component, in particular a track support slab, into a target arrangement.

[0003] A device for displacing an infrastructure component, in particular a track support slab, pre-positioned on a ground into a target arrangement is known from public prior use. The device comprises a first actuating means for receiving a first drive movement for displacing the infrastructure component along a horizontal direction and a second actuating means for receiving a second drive movement for displacing the infrastructure component in a vertical direction. To effect the two linearly independent displacement movements, the first actuating means and the second actuating means are arranged separately from one another on the infrastructure component. Driving the two actuating means is time-consuming, and displacing the infrastructure component into the target arrangement is correspondingly complex.

[0004] It is an object of the invention to provide an improved device for displacing an infrastructure component, in particular a track support plate, pre-positioned on a ground into a target arrangement, which device is particularly easy and time-efficient to handle and economical in operation.

[0005] This object is achieved by a device having the features of claim 1. It has been recognized that a device for displacing an infrastructure component, in particular a track support slab, pre-positioned and supported on a ground into a target arrangement having a ground contact means for supporting on the ground and an actuating device for receiving a first rotational movement about a first axis of rotation can have a transmission device for converting the first rotational movement into a first displacement movement of the ground contact means relative to the infrastructure component with a translatory movement component oriented perpendicular to the first axis of rotation, whereby the device is particularly simple and time-efficient to handle and economical to operate.

[0006] Because the transmission device is designed to convert the first rotational movement, in particular a first drive movement, about the first axis of rotation into a displacement movement with a translational movement component perpendicular to the first axis of rotation, the displacement movement required to displace the infrastructure component can be generated particularly flexibly by a drive movement, for example by a rotational movement about a vertically oriented axis of rotation. By means of the transmission device, the drive movement can be converted into a displacement movement of the ground contact means relative to the infrastructure component with a horizontally oriented, translational movement component. In other words, the infrastructure component can be displaced horizontally on the ground by rotating the actuating device about a vertical axis of rotation.The drive movement in the form of a rotational movement around the first axis of rotation, in particular around the vertical axis of rotation, can be provided in a simple manner. In particular, the actuating device can be attached to the infrastructure component in a particularly flexible manner and thus in an easily accessible arrangement.

The stereo camera 21 is designed to capture the relative position of markers 23 to the measuring device 15, which markers are attached to the respective infrastructure component 4. Based on the relative position of the markers 23 to the measuring device 15 and the measurement position of the measuring device 15 in the global coordinate system, the arrangement of the respective infrastructure component in the global coordinate system can be determined.

[0076] The system 1 comprises a control device 24 with a processor 25 for processing information using a corresponding software program, a memory 26 in which the software program and the acquired measurement data are stored, and a user interface 27 for exchanging information with a user. The measuring device 15 and the control device 24 are particularly designed to continuously determine the arrangement of at least one, in particular at least three, infrastructure components 4, in particular at a frequency of at least 0.1 Hz, in particular at least 0.5 Hz, in particular at least 1 Hz, in particular at least 10 Hz, in particular at least 100 Hz.

[0077] The control device 24 is preferably designed to compare the actual arrangement of the infrastructure component 4 with a desired arrangement, in particular to determine an arrangement deviation. The arrangement deviation preferably comprises the deviation of a position and / or orientation of the infrastructure component 4 from the desired arrangement, which is also referred to below as the target arrangement. The control device 24 can be designed to display the arrangement deviation via the user interface 27, in particular a display, and / or to provide a control signal for the automated relocation of the infrastructure component 4 into the target arrangement, in particular to reduce the arrangement deviation.

In the embodiment shown in Fig.In the embodiment shown in Figure 1, the control communication interface 28 is designed as a wireless communication interface, in particular as a WiFi, ZigBee or Bluetooth interface.

[0078] The respective device 2 has an actuating device 29 for receiving a drive movement for displacing the infrastructure component 4. The actuating device 29 is designed to be driven manually, in particular by means of a wrench, and / or automatically, in particular by means of a drive unit 30. The drive unit 30 is shown in Fig. 1 as an example on one of the devices 2. A corresponding drive unit 30 is preferably arranged on each of the devices 2. This enables the infrastructure component 4, in particular several of the infrastructure components 4, to be displaced simultaneously, automatically, in particular in a coordinated manner, into the target arrangement.

[0079] The drive unit 30 comprises at least one drive motor, in particular two drive motors, in particular electric motors, for providing the drive movement, in particular two independent drive movements. The drive unit 30 can have an energy storage device, in particular for providing electrical energy, in particular a battery, for supplying the at least one drive motor with the required drive energy. Preferably, the two drive movements are provided as coaxial rotary movements.

[0080] The drive unit 30 comprises a drive communication interface 31 for exchanging control information with the control device 24, in particular for receiving the control signals.

[0081] The device is described in further detail with reference to Figs. 2 to 5. The device 2 comprises the actuating device 29, a ground contact means 32 for supporting, in particular, the infrastructure component 4, on the ground 3, a connecting means 33 for fastening the device 2 to the infrastructure component 4, and a transmission device 34 for converting a drive movement exerted on the actuating device 29 into a displacement movement of the infrastructure component 4 relative to the ground 3.

[0082] The actuating device 29 has a first actuating means 35 and a second actuating means 36. The first actuating means 35 and the second actuating means 36 each form a drive interface with an external hexagon profile for receiving a first rotational movement about a first rotational axis 37 and for receiving a second rotational movement about a second rotational axis 38. The first rotational axis 37 and the second rotational axis 38 are arranged coaxially with one another.

[0083] The ground contact means 32 is designed to transfer the weight of the system 1 to the ground 3, in particular to support the infrastructure component 4 on the ground 3. The ground contact means 32 has a contact dome 39 for secure connection to the ground 3. The ground contact means 32, in particular the contact dome 39, is arranged eccentrically to the first axis of rotation 37.

[0084] The connecting means 33 includes, in particular consists of, an external thread 48. The external thread 48 can be designed as a metric thread. Preferably, an external diameter DA of the external thread is in a range from 10 mm to 50 mm, in particular from 15 mm to 40 mm, in particular from 20 mm to 30 mm.

[0085] The counter-connecting means 8 of the infrastructure component 4 comprises, in particular consists of, an internal thread 50. The counter-connecting means 8 is preferably designed to form a screw connection with the connecting means 33. For this purpose, the dimensions of the counter-connecting means 8 preferably correspond to the dimensions of the connecting means 33.

[0086] The diameter di of a core bore of the internal thread 50 of the mating connecting means 8 is preferably in a range from 5 mm to 50 mm, in particular from 10 mm to 40 mm, in particular from 15 mm to 35 mm, in particular from 20 mm to 30 mm. A core diameter dA of the external thread 48 of the connecting means 33 is dimensioned essentially according to the diameter di of the core bore of the mating connecting means 8. The mating connecting means 8 preferably has a threaded insert 41 with the internal thread 50. The threaded insert 41 can be screwed or cast into the plate base body 5. In Fig. 3, the orientation of the eccentric ground contact means 32 about the first axis of rotation 37 is shown using a symbol in the form of a triangular wedge 42. This representation of the orientation of the ground contact means 32 is referred to in the following description of the method for relocating the infrastructure component 4.

[0087] The transmission device 34 has a first transmission means 43 for converting the first rotational movement into a first displacement movement of the ground contact means 32 relative to the infrastructure component 4. The first transmission means 43 comprises a base body 44 to which the ground contact means 32 is eccentrically mounted. The ground contact means 32 is formed integrally with the base body 44; in particular, they are integrally connected to one another. The first transmission means 43 further comprises a shaft 45 for transmitting the first rotational movement between the first actuating means 35 and the base body 44. The shaft 45 has a circular cross-section.A first rotational movement about the first axis of rotation 37 transmitted to the first actuating means 35 can be converted by means of the first transmission means 43 into a first displacement movement of the ground contact means 32 relative to the infrastructure component 4 with a translational movement component oriented perpendicular to the first axis of rotation 37.

[0088] The transfer device 34 has a second transmission means 46. The second transmission means comprises a hollow shaft 47 with an external thread 48. The external thread 48 of the second transmission means 46 is the external thread of the connecting means 33. This external thread 48 accordingly has a dual function. The second transmission means 46 is designed to convert a second rotational movement of the second actuating means 36 about the second axis of rotation 38 into a second displacement movement of the ground contact means 32 relative to the infrastructure component 4 with a translational movement component oriented parallel to the second axis of rotation 38. In other words, the second transmission means 46 is designed to convert a rotational movement of the second actuating means 36 into a movement of the ground contact means 32 relative to the infrastructure component 4 along the second axis of rotation 38.

[0089] The hollow shaft 47 surrounds the shaft 45. In particular, the shaft 45 is rotatably mounted in the hollow shaft 47, in particular by means of a plain bearing and / or a rolling bearing. Preferably, the shaft 45 is positively mounted in the hollow shaft 47 along the first axis of rotation 37, in particular on both sides.

[0090] The first rotation axis 37 and the second rotation axis 38 are oriented substantially perpendicular to a main extension plane 49 of the infrastructure component 4. This ensures that the rotational drive of the first actuating means 35 causes a displacement of the infrastructure component 4 in the vertical direction. The rotational drive of the second actuating means 36 causes a displacement of the infrastructure component 4 in a horizontal direction.

[0091] The device 2 is designed for reversibly penetrating the infrastructure component 4. For this purpose, the connecting means 33 completely overlaps all other elements of the device 2 arranged on the side of the ground contact means 32 with respect to the connecting means 33, in particular along the first axis of rotation 37 and / or along the second axis of rotation 38. In particular, the connecting means 33 completely overlaps the base body 44 and the contact dome 39. In particular, all elements of the device 2 that are located on the side of the ground contact means 32 with respect to the connecting means 33 lie along the first axis of rotation 37 and / or along the second axis of rotation 38 within the outer diameter DA of the internal thread 50, in particular within the diameter di of the core bore, in particular within the core diameter dA of the external thread 48 of the connecting means 33.

[0092] The device 2 penetrates the through-hole core of the infrastructure component 4 completely and reversibly, in particular non-destructively, detachably. In particular, the device 2, in particular the connecting means 33, is designed for reversible, in particular non-destructive and / or disassembly-free, fastening of the device 2 to the infrastructure component 4. In particular, the device 2 is designed for removal from the infrastructure component 4 after the infrastructure component 4 has been cast with the ground 3 by means of the filler 10 and after the filler 10 has hardened.

[0093] The total length L of the device 2 is preferably in a range from 200 mm to 600 mm, in particular from 300 mm to 500 mm, in particular from 350 mm to 450 mm. A length 1 of the external thread 48 is preferably less than the total length L. The length difference is preferably in a range from 10 mm to 200 mm, in particular from 20 mm to 100 mm, in particular from 30 mm to 60 mm. The total length L of the device 2 and / or the thread length 1 of the external thread 48 are preferably greater than the thickness t of the infrastructure component 4, in particular of the slab base body 5, in particular of the track support slab. The thickness t of the infrastructure component 4 is preferably in a range from 100 mm to 500 mm, in particular from 200 mm to 400 mm.

[0094] A distance c between the first actuating means 35 and the second actuating means 36, in particular along the first axis of rotation 37, is preferably in a range from 0 mm to 100 mm, in particular from 5 mm to 50 mm, in particular from 10 mm to 20 mm.

[0095] The functioning of the system 1, in particular the device 2, the combination 16, and the method for relocating the infrastructure component 4 is as follows:

[0096] By means of a transport device not shown, in particular by means of a carriage and / or a crane and / or a multi-joint arm, several of the infrastructure components 4 are pre-positioned one after the other on the ground 3, in particular within an area enclosed for casting, preferably vertically overlapping the reinforcement 11.

[0097] In this pre-positioned arrangement, which is also referred to below as the initial arrangement, the respective infrastructure component 4 is supported on the ground 3 by means of the ground contact means 32 of the device 2. Five of the devices 2 are fastened to the respective infrastructure component 4. The devices 2 penetrate the respective infrastructure component 4, in particular the base plate 5 of the track support slab, such that the ground contact means 32 protrudes downwards from the infrastructure component 4. The actuating device 29 of the respective device 2 protrudes upwards from the infrastructure component 4.

[0098] A drive unit 30 is attached to each of the actuating devices 29 and is in signal connection with the control device 24.

[0099] The measuring device 15 is located in a measuring position. The position determination unit 17 determines the distance to the respective land survey points 18, in particular by detecting the target windows 19 of the reflector rods 20. Based on these distances, the measuring position of the measuring device 15 is determined, in particular by means of the control device 24, in particular in a global coordinate system, and preferably stored in the memory 26 of the control device 24.

[0100] The arrangement of the respective infrastructure component 4 is recorded by means of the measuring device 15, in particular by detecting the markings 23. In particular, the stereo camera 21 records the position of the markings 23 relative to the measurement position of the measuring device 15. The arrangement of the infrastructure components 4, in particular the actual arrangement, is determined based on the image analysis and the measurement position, in particular by means of the control device 24, in particular in a global coordinate system, and preferably stored in the memory 26 of the control device 24. The control device 24 determines the arrangement deviation between a desired arrangement, in particular the target arrangement, and the actual arrangement of the infrastructure components 4. A control signal correlating with the arrangement deviation is determined by means of the control device 24.The control signal is transmitted to the respective drive unit 30, in particular via the wireless signal connection with the control communication interface 28 and the respective drive communication interface 31.

[0101] In accordance with the control signal, the drive unit 30 drives the first actuating means 35 and the second actuating means 36, in particular independently of one another, about the first axis of rotation 37 and about the second axis of rotation 38. Based on the control signal, all drive units 30 act on the devices 2, in particular the actuating devices 29, in such a way that the infrastructure component 4 is displaced from the initial arrangement to the target arrangement.

[0102] The rotational drive of the first actuating means 35 causes the infrastructure component 4 to be displaced in the region of the respective device 2, in particular in the region of the associated counter-connecting means 8, in the horizontal direction. The rotational drive of the second actuating means 36 of the respective device 2 causes the infrastructure component 4 to be displaced in the region of the respective device 2, in particular in the region of the associated counter-connecting means 8, in the vertical direction.

[0103] Because the ground contact means 32 has the contact dome 39 arranged eccentrically to the first rotation axis 37, the infrastructure component 4 is displaced in a circular motion around the contact dome 39 when the first actuating means 35 is driven in rotation. The radius of the circular motion corresponds to the distance r of the contact dome 39 from the first rotation axis 37. The distance r is 10 mm. Upon a complete rotation of the first actuating means 35 about the first rotation axis 37, the infrastructure component 4 is displaced in the region of the corresponding device 2 in the horizontal direction by + / - 10 mm relative to the ground 3.

[0104] Preferably, the control device 24 is designed to control the drive units 30 in such a way that the total required displacement movement of the infrastructure component 4 relative to the floor 3 and / or the displacement duration are as short as possible.

[0105] The infrastructure components 4 are shifted from the initial arrangement to the target arrangement. The target arrangement deviates from the target arrangement, particularly in the area of ​​the markings 23, by a maximum of 5 mm, particularly by a maximum of 2 mm, particularly by a maximum of 1 mm, particularly by a maximum of 0.5 mm, particularly in the horizontal direction, particularly perpendicular to a longitudinal direction of the rails 7.

[0106] The relocation of the respective infrastructure component 4 is described in further detail with reference to Figs. 6A to 6C. For better understanding, the five devices 2 are individually labeled as devices 2.1 to 2.5, distinguishable from one another. The arrangement of the ground contact means 32, in particular the contact dome 39, around the first rotation axis 37, is symbolized by the tip of the triangular wedge 42.

[0107] An x-direction and a y-direction of a Cartesian coordinate system, particularly shown in Fig. 6A, extend in the horizontal plane. The x-direction is oriented parallel to a longitudinal direction of the rails 7. The y-direction is oriented perpendicular to the longitudinal direction of the rails 7. A z-direction is oriented vertically, in particular upwards. The x-direction, the y-direction, and the z-direction form a right-handed coordinate system. Preferably, a main extension plane 49 of the infrastructure component 4, in particular of the slab base body 5, is oriented substantially parallel to the x-direction and the y-direction, in particular to the horizontal plane.

[0108] In Fig. 6A, the system 1, in particular the infrastructure component 4 and the devices 2, is in the initial configuration. The contact domes 39 of each of the devices 2 are arranged at a distance from the respective first rotation axis 37, counter to the y-direction. Accordingly, the dirt-shaped wedges 42 point counter to the y-direction.

[0109] The first actuating means 35 are rotationally driven about the first rotation axis 37. The ground contact means 32, in particular the contact dome 39, is rotated by 90°, in particular clockwise, about the first rotation axis 37. The infrastructure component 4 is thereby displaced in the horizontal direction, in particular in the x-direction and y-direction, relative to the ground 3.

[0110] Fig. 6B shows the system 1 in a first displacement arrangement. Compared to the initial arrangement, the infrastructure component 4 in the first displacement arrangement is displaced in the x-direction by xi = 10 mm and in the y-direction by yi = -10 mm. The respective ground contact means 32, in particular the contact dome 39, is arranged at a distance from the first axis of rotation 3 opposite to the x-direction. The triangular wedge 42 of the devices 2 accordingly points opposite to the x-direction. The first actuating means 35 is rotated further about the first axis of rotation 37, in particular clockwise, in particular again by 90°. As a result, the infrastructure component 4 is displaced relative to the ground 3 opposite to the x-direction and further opposite to the y-direction.

[0111] Fig. 6C shows the system 1, in particular the infrastructure component 4, in a second displacement configuration. Compared to the initial configuration, the infrastructure component 4 is displaced in the second displacement configuration by X2 = 0 mm in the x-direction and by y2 = -20 mm in the y-direction. The ground contact means 32 is arranged at a distance from the first rotation axis 37 in the y-direction.

[0112] In order to displace the infrastructure component 4 over a greater, in particular horizontal, distance, in particular beyond twice the distance r between the first rotation axis 37 and the contact point 39, the devices 2 can be realigned, in particular one after the other. The realignment of the devices 2 is described with reference to Figs. 7A to 7C.

[0113] Fig. 7A shows the system 1 in the second displacement configuration. To realign the device 2.1, it is displaced along the second rotation axis 38, in particular vertically upward, by rotating the second actuating means 36. The ground contact means 32 of the device 2.1 is disengaged from the ground 3. The first actuating means 35 is then rotationally driven to align the ground contact means 32 according to the initial configuration. The infrastructure component 4 retains its position and orientation relative to the ground 3.

[0114] The second actuating means 36 is driven in rotation about the second rotation axis 38 to lower the device 2.1. The ground contact means 32 again comes into contact with the ground 3. The infrastructure component 4 is again supported on the ground 3 via the device 2.1. The system 1 is in the first alignment configuration shown in Fig. 7B.

[0115] The method described above is repeated successively for each of the devices 2.2 to 2.5. The devices 2.1 to 2.5 are then oriented relative to the infrastructure component 4 according to the initial arrangement, with the infrastructure component 4 not having changed its arrangement compared to the second relocation arrangement. The system 1, in particular the infrastructure component 4, can be relocated further counter to the y-direction relative to the ground 3 according to the method described with reference to Figs. 6A to 6C.

[0116] With reference to Fig. 8A to Fig. 8B, it is described how the system 1 can be fixed particularly stably to the ground 3. Depending on the height of the infrastructure component 4 above the ground 3 and a fit between the connecting means 33 and the counter-connecting means 8 and / or the elasticity of the device 2, a force input to the infrastructure component 4, in particular in the horizontal direction, can lead to an unwanted relative movement of the infrastructure component 4 relative to the ground 3. This could impair the precise arrangement of the infrastructure component

[0117] 4 in the target arrangement. A corresponding force input can occur, for example, when the infrastructure component 4 is cast with the filler 10.

[0118] By means of the devices, the infrastructure component 4 can be fixed, in particular braced, in the target arrangement. For this purpose, the devices 2, in particular the first actuating means 35, are rotationally driven in pairs in opposite directions. In particular, the first actuating means 35 of the devices 2.1 and 2.3 are rotationally driven in opposite directions, and the first actuating means 35 of the devices 2.2 and 2.4 are rotationally driven in opposite directions. The displacement movement of the respective ground contact means 32 about the first axis of rotation is preferably in a range from 2° to 60°, in particular from 5° to 45°, in particular from 10° to 30°, in particular from 15° to 20°. The infrastructure component 4 preferably does not move relative to a ground 3. The bracing can be carried out by applying a predetermined torque to the respective device, in particular the first actuating means 35.The relative movement of the ground contact means 32 to the infrastructure component 4 causes an elastic deformation of the respective device 2, which clamps the infrastructure component 4 in the target arrangement to the ground 3. The system 1 is located in the clamping arrangement shown in Fig. 8B. The clamping arrangement preferably corresponds to the target arrangement.

[0119] As an alternative to the automatic execution using the drive units 30, the method described above can also be carried out manually. For this purpose, the arrangement deviation is displayed on the user interface 27. The user can drive the actuating device 29, in particular the first and second actuating means 35, 36, using a tool, in particular a wrench, such that the infrastructure component 4 is displaced into the target arrangement and / or clamped in the target arrangement.

[0120] In the target arrangement, in particular in the prestressing arrangement, the at least one infrastructure component 4 is cast with the filler 10, in particular with pourable concrete. The free space 14 between the ground 3 and the infrastructure component 4 is filled with the filler. The filler hardens. The infrastructure component 4 is firmly connected to the ground 3 via the hardened filler 10.

[0121] The devices 2 can be removed from the respective infrastructure component 4. For this purpose, the second actuating means 36 is driven in rotation about the second rotation axis 38, and the respective device 2 is removed from the device 2 in the vertical direction, in particular in the z-direction. The device 2 can be used to relocate the infrastructure components 4 into a target arrangement.

[0122] A further embodiment of the system 1 with the at least one device 2 is described with reference to Figs. 9 to 12. In contrast to the embodiment described above, the device 2 has a ground contact means 32 with a rotatably mounted contact dome 39. The contact dome 39 is cylindrical in sections. An end face of the cylindrical section of the ground contact dome 39, in particular facing the infrastructure component 4, is cylindrical, in particular spherical segment-shaped. The ground contact means 32 comprises a pivot bearing 51, in particular an axial bearing. The pivot bearing 51 is designed as a rolling bearing, in particular as a ball bearing.

[0123] The contact dome 39 is mounted on the transmission device 34, in particular on the first transmission means 43, in particular on the base body 44, by means of the pivot bearing 51, so as to be rotatable about a bearing axis 52. The bearing axis 52 is oriented parallel to the first axis of rotation 37. A distance r between the bearing axis 52 and the first axis of rotation 37 corresponds to the distance r between the first axis of rotation 37 and the tip of the contact dome 39. In particular, the contact dome 39 is rotationally symmetrical about the bearing axis 52.

[0124] Along the first axis of rotation 37, the contact dome 39 projects beyond the base body 44, with respect to the transmission device 34 in the direction of the ground contact means 32, by a height h in a range from 1 mm to 30 mm, in particular from 2 mm to 20 mm, in particular from 3 mm to 15 mm, in particular from 4 mm to 10 mm.

[0125] The system 1 comprises a counter-ground contact means 53. The counter-ground contact means 53 is designed to transmit the force transmitted to the ground 3 via the ground contact means 32, in particular the contact dome 39, in particular the weight of the infrastructure component 4, into the ground 3 in a particularly evenly distributed manner, in particular distributed over an enlarged area. The counter-ground contact means 53 preferably comprises a plate, in particular a metal plate, in particular a steel plate. The counter-ground contact means 53 has a square base with a side length of 200 mm. The thickness of the counter-ground contact means 53 is 15 mm. The system 1 and the device 2 otherwise correspond to the previously described embodiment. The mode of operation corresponds to that of the previously described embodiment.

[0126] The rotatable mounting of the ground contact means 32 relative to the base body 44 advantageously reduces the friction between the ground contact means 32 and the ground 3. The device 2 is thereby particularly easy to operate; in particular, the actuating device 29, in particular the first actuating means 35, can be driven particularly smoothly and with low friction. The counter-ground contact means 53 improves the force introduction between the device 2 and the ground 3. In particular, the weight of the infrastructure component 4 transmitted via the ground contact means 32 can be transmitted over a larger area by means of the counter-ground contact means 53 and thus introduced into the ground 3 in a particularly evenly distributed manner, in particular with a reduced surface load. Damage to the ground 3 is avoided. The displacement of the infrastructure component 4 relative to the ground 3 can be carried out particularly reliably by means of the device 2.

[0127] The devices 2, in particular the combination 16, enable the relocation of an infrastructure component 4 pre-positioned on a floor 3 into a target arrangement in a particularly precise and economical manner. The device 2 and / or the combination 16 are fully reusable. In particular, after the infrastructure component 4 has been cast and cured on the floor 3, the device 2 can be completely removed from the device 2, in particular non-destructively and / or without disassembly, and is thus ready for reuse for relocating another infrastructure component 4. Due to the spatial proximity of the first actuating means 35 and the second actuating means 36, in particular due to their coaxial rotation axes 37, 38, the driving of the device 2, in particular the actuating device 29, can be carried out in a particularly easy-to-handle manner, in particular in an automated manner.Because the infrastructure component 4 can be fixed, in particular clamped, in the target arrangement by means of the device 2, a displacement of the infrastructure component 4 from the target arrangement, in particular during casting with the filler 10, can be reliably avoided.
