Description

Concreting system and method for operating a concreting system

[0001] The invention relates to a concreting system for the production of precast concrete elements and a method for operating a concreting system.

[0002] Precast concrete elements are typically manufactured in an assembly hall, where production can take place without being affected by weather conditions. The final use of the precast concrete element usually occurs at a location outside the assembly hall, to which it is transported.

[0003] Currently, concrete pumps are frequently used for the production of precast concrete elements. These pumps are mounted on a turntable in a central area of ​​the assembly hall. A height-adjustable boom on the pump allows liquid concrete to be dispensed to various areas of the hall for the production of precast components. This method requires a significant amount of floor space for the concrete pump, space that cannot be used for the production of precast concrete elements. Alternative options include belt conveyors mounted on a similar turntable, which also occupy considerable floor space. With a so-called rotary distributor, support structures project far outwards, which is mechanically complex. Bucket conveyors, used to transport the liquid concrete in batches, are also complex and require an elaborate rail system.

[0004] The invention is based on the objective of presenting a concreting system with which these disadvantages are reduced. The problem is solved by the features of the independent claims. Advantageous embodiments are specified in the dependent claims.

[0005] A concrete placement system according to the invention for producing precast concrete elements comprises a first belt conveyor, a second belt conveyor, and a distribution bridge. The distribution bridge spans a gap between a first guide rail and a second guide rail. The distribution bridge is movable along the guide rails. An overlap zone exists between the first belt conveyor and the second belt conveyor, such that liquid concrete discharged from the first belt conveyor is fed to the second belt conveyor. The second belt conveyor communicates with the distribution bridge, so that liquid concrete discharged from the second belt conveyor is fed to the distribution bridge. The length of the overlap zone between the first belt conveyor and the second belt conveyor is adjustable.The distribution bridge is designed to move the position of an outlet end of the concreting system in such a way that the movement of the outlet end includes a movement in a direction transverse to the direction of the guide rails.

[0006] The invention proposes a concrete placement system that can be used in an assembly hall without requiring much floor space. The arrangement, consisting of the distribution bridge and the belt conveyors, can be housed in an upper area of ​​the assembly hall. The concrete placement system allows for a low overall height and can therefore be positioned, for example, near the hall ceiling. The system can be designed so that the position at which the liquid concrete is dispensed via the distribution bridge can be changed, while the height of the distribution bridge and the belt conveyors remains constant. This allows for flexible use of the space on the floor of the assembly hall and thus an overall improved usability of the assembly hall.

[0007] The first and second belt conveyors can be aligned parallel to each other. The first belt conveyor can be arranged in a first plane, and the second belt conveyor can be arranged in a second plane. The first plane can be aligned parallel to the second plane. The first plane can be a horizontal plane. The second plane can also be a horizontal plane. It is also possible for the first and / or the second plane to be a slightly inclined plane. The length of the overlap area between the first and second belt conveyors can be changed by moving the first and second belt conveyors linearly relative to each other. The direction of this linear movement can be parallel to the conveying direction of the first and / or second belt conveyor.

[0008] The first belt conveyor can have a fixed position relative to the guide rails. The length of the overlap area can be changed by moving the second belt conveyor relative to the first. The concreting system can be configured so that the distributor bridge moves synchronously with the second belt conveyor relative to the guide rails. This ensures that, despite the changed position of the second belt conveyor, the liquid concrete discharged by the second belt conveyor can continue to be fed to the distributor bridge.

[0009] The second belt conveyor can be positioned between a first The concreting system can extend to a first end and a second end. The concreting system can include a first system state in which the handover takes place. The transfer of liquid concrete from the second belt conveyor to the distribution bridge at the first end of the second belt conveyor takes place. The concreting system can include a second system state in which the transfer of liquid concrete from the second belt conveyor to the distribution bridge at the second end of the second belt conveyor occurs. The conveying direction of the second belt conveyor can be opposite to the conveying direction of the second belt conveyor in the second system state. The conveying direction of the second belt conveyor can be reversible.

[0010] The concreting system can be configured such that, in the first system state, the distributor bridge moves synchronously with the second belt conveyor, and in the second system state, the spreader bridge moves synchronously with the second belt conveyor. For a transition between the first and second system states, the distributor bridge can be moved relative to the second belt conveyor. The travel path can be parallel to the conveying direction of the second belt conveyor. The length of the distributor bridge's travel path relative to the second belt conveyor can correspond to the length of the second belt conveyor. In particular, the difference between the length of the travel path and the length of the second belt conveyor can be less than 10%, preferably less than 5%, and more preferably less than 2%.

[0011] The first belt conveyor can extend between its proximal and distal ends. At the proximal end, the liquid concrete is fed into the first belt conveyor; at the distal end, the liquid concrete is transferred to the second belt conveyor. The first belt conveyor can have a fixed conveying direction that does not change between the first and second system states of the concreting system.

[0012] The concrete placement system can include a feed device through which the liquid concrete is fed to the proximal end of the first belt conveyor. The system can also include a pre-filling hopper through which the liquid concrete is fed to the feed device. The liquid concrete can be supplied to the pre-filling hopper from an intermediate container. This intermediate container could, for example, be a bucket filled with liquid concrete that can be moved within the assembly hall using a crane. Alternatively, the liquid concrete can be supplied directly from a concrete mixer truck. For this to be advantageous, the pre-filling hopper should be positioned so that it can be accessed from outside the assembly hall. The liquid concrete can also be supplied directly from a mixing plant. The advantage of this is that different concrete qualities can be applied sequentially.

[0013] The concrete placement system allows for the definition of a conveying path extending from the first belt conveyor, or any upstream components of the system, through the second belt conveyor and the distribution bridge to a discharge point. At the discharge point, the liquid concrete can fall from the concrete placement system. The discharge point can be positioned so that the falling concrete lands in a formwork whose shape corresponds to a precast concrete element being produced. A discharge hose can be connected to the discharge point, through which the liquid concrete falls downwards.

[0014] The distributor bridge can be designed to change the position of the outlet end relative to the second belt conveyor. In particular, the movement of the outlet end can include a movement in a transverse direction relative to the second belt conveyor. The transverse direction is a horizontal direction that forms a right angle with the direction of the travel path of the distributor bridge along the guide rails. The angle between the direction of movement of the outlet end and the transverse direction can be less than 20°, preferably less than 10°, and more preferably less than 5°.

[0015] The distribution bridge can include a pivot arm, the distal end of which forms the outlet end. With a pivot arm, movement of the outlet end in the transverse direction is coupled with movements in other directions; that is, it is generally not possible to move the outlet end linearly in the transverse direction with a pivot arm. The pivot arm can be mounted on a support of the distribution bridge via a pivot bearing. The support can be supported on the first and second guide rails and bridge the distance between them. The pivot bearing can have a vertical axis. The pivot range of the pivot arm relative to the support of the distribution bridge can extend over at least 180°, preferably at least 270°. In one embodiment, the pivot range of the pivot arm extends over 360°.The distributor bridge has the ability to distribute the liquid concrete spatially via such a swivel arm.

[0016] The swivel arm can include a conveyor belt that conveys the liquid concrete from an end of the swivel arm adjacent to the distributor bridge support towards the discharge end. The swivel arm can have an adjustable length. For example, the swivel arm can be designed as a telescopic mechanism, allowing its length to be changed by moving two components of the swivel arm longitudinally relative to each other. Each component of the swivel arm can be connected by a A conveyor belt can be formed. A belt conveyor and a conveyor belt within the meaning of the invention can have a comparable structure and a comparable function.

[0017] The distribution bridge can include a conveying mechanism for transporting the liquid concrete along the bridge. The conveying mechanism can be designed as a belt conveyor. The length of the conveying mechanism can be adjustable, for example, by allowing two components of the mechanism to be moved longitudinally relative to each other, similar to a telescopic mechanism.

[0018] An end hose can be attached to the outlet end, through which the pumped liquid concrete falls downwards. The end hose can be flexible. The concreting system can be equipped with a valve to prevent liquid concrete from passing through the end hose. Such a valve makes it possible to precisely control when the flow of liquid concrete begins or ends. The valve can be designed as a pinch valve that compresses the end hose when the valve is closed.

[0019] The concreting system may include a primary cleaning device to remove residual liquid concrete from the first belt conveyor. The cleaning device may be equipped with a spraying unit that sprays a liquid, particularly water, onto the first belt conveyor. A collection device may be provided to collect the used liquid or a mixture of the liquid and the liquid concrete. The cleaning device may include a scraper that removes residual liquid concrete from components of the first belt conveyor. For a cleaning operation, the first The belt conveyor is kept in operation so that components contaminated with liquid concrete are moved relative to the cleaning device, allowing different areas of the first belt conveyor to be cleaned.

[0020] The concreting system may include a second cleaning device to remove residual liquid concrete from the second belt conveyor. The second cleaning device may, individually or in combination, have the features described in connection with the first cleaning device. If the concreting system has additional elements designed like a belt conveyor, one or more further cleaning devices may be provided, each assigned to one of these additional elements.

[0021] The concrete placement system can be designed to perform a cleaning process when switching from one type of liquid concrete to another. For such a changeover, the supply of the first type of concrete to the first conveyor belt can be interrupted, preventing any new concrete from arriving at the first conveyor belt. Once the last of the concrete has been transferred to the second conveyor belt, the first conveyor belt can be kept running and the first cleaning device activated. After a complete cycle of the first conveyor belt, it is sufficiently cleaned and ready to receive the second type of concrete.

[0022] A cleaning process can be carried out on the second conveyor belt at a time staggered from the cleaning process of the first belt conveyor. After the last of the concrete has been transferred to the distribution bridge, the second conveyor belt can be kept running and the second cleaning unit activated. New concrete can then be fed into the first conveyor belt before the cleaning process begins. the second belt conveyor is completed. In this way, the time loss resulting from the cleaning process between switching from one type of concrete to a second type of concrete can be kept to a minimum.

[0023] The concreting system can include a vibrator. The vibrator can be mounted on the distribution bridge. A vibrator is a device used to compact fresh concrete. By including the vibrator as a component of the concreting system, the system can both place the fresh concrete and perform a subsequent work step immediately afterward. This enables an efficient method of working in the production of precast concrete elements.

[0024] The concreting system can include a control unit designed to manage the interaction of its components. The concreting system can include one or more position sensors that provide a measurement of the position of the discharge end. In one implementation, the position is measured relative to the guide rails of the concreting system. The control unit can be designed to process the position measurements as input to generate control commands that actuate actuators of the concreting system, either individually or in combination. A first actuator can be controlled to move the distributor bridge along the guide rails. A second actuator can be controlled to move the first belt conveyor relative to the second belt conveyor. A third actuator can be controlled to change the position of the discharge end relative to the second belt conveyor.Additional actuators can be controlled to start or stop the delivery of the first belt conveyor, the second belt conveyor and / or the distribution bridge.

[0025] The concrete placement system can include more than two belt conveyors connected in series, so that the liquid concrete is transferred from a preceding belt conveyor to a subsequent one. The overlap area between each pair of successive belt conveyors can be adjustable. The liquid concrete can be transferred from the last belt conveyor in the series to the distribution bridge. The first belt conveyor in the series can be in a fixed spatial relationship to the guide rails.

[0026] The invention also relates to an assembly hall equipped with such a concreting system. The concreting system can be operated within the assembly hall. The assembly hall can include a crane that can be moved in a horizontal plane without requiring space on the floor of the assembly hall. The crane can be located closer to the ceiling of the assembly hall than to the floor. The first and second belt conveyors of the concreting system can be arranged in a vertical position above the crane.

[0027] A platform may be provided in the assembly hall from which maintenance work can be carried out on the concrete system. The platform may be positioned at a height that allows access to the belt conveyor for a person standing on it. The platform may also be positioned so that the belt conveyor is accessible when it is retracted to the shortest distance between its proximal and distal ends. In addition to or as an alternative to such a platform, one or more walkways may be provided, extending parallel to one, several, or all of the belt conveyors. Walkways can be arranged so that a person standing on the walkway can clean the conveyor belt. A similar walkway can also be provided for the distribution bridge.

[0028] The assembly hall can be a conventional assembly hall, which may have a fixed roof and fixed side walls. This also includes designs where the side walls and / or the roof consist entirely or partially of a tarpaulin-like material. Alternatively, the concrete pouring system can also be operated outdoors.

[0029] The invention also relates to a method for operating a concrete placement system, wherein the concrete placement system comprises a first belt conveyor, a second belt conveyor, and a distribution bridge. The distribution bridge spans a gap between a first guide rail and a second guide rail. The distribution bridge is moved along the guide rails. There is an overlap area between the first belt conveyor and the second belt conveyor, so that liquid concrete discharged from the first belt conveyor is fed to the second belt conveyor. The second belt conveyor communicates with the distribution bridge, so that liquid concrete discharged from the second belt conveyor is fed to the distribution bridge. The length of the overlap area between the first belt conveyor and the second belt conveyor is varied to position an outlet end of the concrete placement system attached to the distribution bridge.The position of an outlet end of the concreting system is arranged relative to the distributor bridge in such a way that the movement of the outlet opening includes a movement in a direction transverse to the direction of the guide rails.

[0030] The concreting system can be cleaned by performing an initial cleaning process on the first belt conveyor. a second cleaning process is carried out on the second belt conveyor, the second cleaning process being carried out after the first cleaning process and liquid concrete being supplied to the first belt conveyor before the second cleaning process is completed.

[0031] The disclosure includes further developments of the method that are described in connection with the concreting system according to the invention.

[0032] The invention is described below by way of example with reference to the accompanying drawings and advantageous embodiments. The drawings show: Fig. 1: an assembly hall with a concreting system according to the invention; Fig. 2: the view according to Fig. 1 in a different state of the concreting system; Fig. 3: a schematic side view of a concreting system according to the invention; Fig. 4: the view according to Fig. 3 in a different state of the concreting system; Fig. 5: the state according to Fig. 4 in a top view; Fig. 6-8: the view according to Fig. 3-5 in a different state of the concreting system; Fig. 9: an alternative embodiment of a distributor bridge according to the invention in a side view; Fig. 10: the view according to Fig. 5 in an alternative From the implementation form of the invention; Fig. 11: another embodiment of a concreting system according to the invention.

[0033] A concreting system according to the invention is arranged in an assembly hall 14. The concreting system defines a conveying section for liquid concrete that extends from a pre-filling hopper 15 to an end hose 26. The pre-filling hopper 15 is located outside the assembly hall 14, so that the liquid concrete can be filled into the pre-filling hopper 15 from a mobile concrete mixer. A feeding device 20 extends from the pre-filling hopper 15 to a first belt conveyor 16. The first belt conveyor 16 conveys the liquid concrete towards a second belt conveyor 17, from which the liquid concrete is transferred to a distribution bridge 25. Via the distribution bridge 25, the liquid concrete enters an end hose 26, at the lower end of which an outlet 46 of the concreting system is formed.

[0034] Figure 2 shows a state of the concreting system in which the second belt conveyor 17, together with the distributor bridge 25, is displaced in the X-direction 36, thereby changing the position at which the liquid concrete exits the end hose 26. The ability to displace the end hose 26 is used to dispense the liquid concrete in such a way that the precast concrete elements 18 can be produced.

[0035] According to Fig. 5, the distributor bridge 25 rests on two Guide rails 21, 22, which extend in the X direction 36 and which have a distance 51 from each other in the Y-direction 37. The distributor bridge 25 bridges the distance between the guide rails 21, 22 and projects beyond the first guide rail 21 on one side. The distributor bridge 25 is mounted on the guide rails 21, 22 so as to be movable in the X-direction 35. The first belt conveyor 16 and the second belt conveyor 17 extend parallel to the guide rails 21, 22. The distributor bridge 25 is positioned such that liquid concrete coming from the second belt conveyor 17 hits a receiving area 27 of the distributor bridge 25.

[0036] On the distributor bridge 25, the liquid concrete is conveyed by a conveying mechanism (not shown) to the position on the distributor bridge 25 where the end hose 26 is attached. The liquid concrete falls into the end hose 26 and exits at its lower end. By moving the distributor bridge 25 along the guide rails 21, 22 and by sliding the end hose 26 along the distributor bridge 25, the end hose 26 can be positioned in the XY plane. The position of the end hose 26 in the XY plane is adjusted so that the liquid concrete exits at the desired location.

[0037] The first belt conveyor 16 extends between a proximal end 33 and a distal end 34, see Fig. 3. Liquid concrete, fed by the feed device 20 to the proximal end 33 of the first belt conveyor 16, is transported in the conveying direction 35 until it falls off the first belt conveyor 16 at the distal end 34 and lands on the second belt conveyor 17. The second belt conveyor 17 extends between a first end 31 and a second end 32. In Fig. 3, the belt conveyor 17 is operated such that the conveying direction 35 runs from the first end 31 to the second end 32. The liquid concrete falls from the second belt conveyor 17 at the second end 32 and lands on the receiving area 27 of the distribution bridge 25.

[0038] The second belt conveyor 17 is movable in the X-direction 36, so that the second end 32 of the second belt conveyor 17 can be positioned appropriately for the distributor bridge 25 even when the distributor bridge 25 is moved in the X-direction. Depending on the position of the second belt conveyor 17 in the X-direction, the overlap area 38 between the first belt conveyor 16 and the second belt conveyor 17 becomes larger or smaller. Depending on the length of the overlap area 38, the position at which liquid concrete coming from the first belt conveyor 16 lands on the second belt conveyor 17 changes.

[0039] Figures 3 and 4 show a first system state of the concrete pouring system in which the conveying direction 35 on the second belt conveyor 17 points in the same direction as on the first belt conveyor 16. In the first system state, the second belt conveyor 17 and the distribution bridge 25 are coupled to each other in such a way that movement in the X-direction can only occur together. This ensures that the liquid concrete can fall from the second end 32 of the second belt conveyor 17 onto the receiving area 37 of the distribution bridge 25 at any time within the first system state.

[0040] Figures 6 and 7 show the transition between the first system state and a second system state of the concreting system. For the transition, the coupling between the distributor bridge 25 and the second belt conveyor 17 is released, so that the distributor bridge 25 can be moved to the first end 31 of the second belt conveyor 17. The distributor bridge 25 is positioned so that from the first end 31 of the second Liquid concrete falling from belt conveyor 17 lands on the receiving area 27 of the distributor bridge 25. In the second system state, the second belt conveyor 17 is operated in the opposite conveying direction 35, so that liquid concrete falling onto the second belt conveyor 17 is transported to the first end 31 of the second belt conveyor 17.

[0041] After reaching the second system state, the distributor bridge 25 and the second belt conveyor 17 are coupled together again, so that they can only be moved together in the X-direction 36. Similar to the first system state, the end hose 26 can be positioned so that the liquid concrete exits at the desired location.

[0042] For the proper operation of the concreting system, the overlap area 38 between the first belt conveyor 16 and the second belt conveyor 17 is required. This ensures that liquid concrete coming from the first belt conveyor 16 lands on the second belt conveyor 17. The adjustment range X-direction 36 of the distributor bridge 25 is limited by the requirement of the overlap area 38. In the first system state, it is therefore not possible to move the distributor bridge further to the left than to the distal end 34 of the first belt conveyor 16, see Fig. 6. By moving the distributor bridge 25 to the first end 31 of the second belt conveyor 17, an area in the X-direction 36 becomes accessible to the distributor bridge 25 in the second system state, which is not accessible in the first system state. Thus, the operating range of the concreting system is extended by switching between the first and second system states.

[0043] Figure 10 shows an alternative embodiment of a The concreting system is shown, in which the distributor bridge 25 is equipped with a swivel arm 40. According to Fig. 9, the The swivel arm 40 is suspended from the distributor bridge 25 via a pivot bearing 43. The swivel arm 40 can be pivoted over a rotation angle of 180°, with the swivel arm 40 extending parallel to the X-direction 36 at both limits of the pivot range.

[0044] Liquid concrete falling onto the receiving area 27 of the distribution bridge 25 is conveyed towards an opening 43 of the distribution bridge 45, through which the liquid concrete falls onto a proximal end 45 of the pivoting arm 40. The pivoting arm 40 comprises a first conveyor belt 41 and a second conveyor belt 42, which are arranged one behind the other in the longitudinal direction of the pivoting arm 40. Liquid concrete falling onto the proximal end 45 is conveyed by the first conveyor belt 41 towards the second conveyor belt 42 and from there to the distal end 46 of the pivoting arm 40. At the distal end 46, the liquid concrete falls from the pivoting arm 40. The distal end 46 of the pivoting arm 40 forms an outlet end of the concreting system.

[0045] The distance between the proximal end 45 and the distal end 46 of the swivel arm 40 can be changed by moving the second conveyor belt 42 in the longitudinal direction 44 of the swivel arm 40 relative to the first conveyor belt 41. By positioning the swivel arm 40 at a suitable angle relative to the distributor bridge 25 and by adjusting the swivel arm 40 to a suitable length, the liquid concrete can be dispensed in a desired position. The opening 43 can be arranged in a fixed position within the distributor bridge 25.

[0046] A vibrator 52 is attached to the distributor bridge 25 and is movable in the Y-direction 37 relative to the distributor bridge 25. The vibrator 52 is a device used for compacting fresh concrete. As a component of the concreting system, the vibrator 52 can The concreting system allows both the placement of fresh concrete and the immediate subsequent work step to be carried out. This enables an efficient working method in the production of precast concrete elements.

[0047] Fig. 11 shows an alternative embodiment of a concrete pouring system according to the invention, in which the first belt conveyor 16 is equipped with a first cleaning device in the form of a first spray device 47 and the second belt conveyor 17 is equipped with a second cleaning device in the form of a second spray device 48.

[0048] Once the supply of liquid concrete to the first conveyor belt 16 is interrupted, the first spray device 47 can be activated, spraying the surface of the first conveyor belt 16 with water. Liquid concrete adhering to the first conveyor belt 16 is washed away. The mixture of water and liquid concrete falls into a collection trough 49 located below the first spray device 47. After a complete rotation of the first conveyor belt 16, it is cleaned and ready to receive new liquid concrete. The second spray device 48 can be used in a similar manner to clean the second conveyor belt 17.

[0049] This enables the following process during the transition from one type of concrete to a second type of concrete. After interrupting the supply of liquid concrete to the first conveyor belt 16, a cleaning process can be carried out on the first conveyor belt 16. The cleaning process begins while liquid concrete is still falling from the first conveyor belt 16 onto the second conveyor belt 17. The cleaning process on the second conveyor belt 17 is carried out sequentially after the cleaning process on the first conveyor belt 16. Conversely, this means that the cleaning process The cleaning process on the first conveyor belt 16 must be completed before the cleaning process on the second conveyor belt 17 is completed. New liquid concrete can be fed to the first conveyor belt 16 while the cleaning process on the second conveyor belt 17 is still underway. The timing should be such that the cleaning process on the second conveyor belt 17 is completed before the new liquid concrete falls onto the second conveyor belt 17. In this way, a quick changeover to a new type of liquid concrete can be carried out without the new liquid concrete being contaminated by residues of the previous type of concrete.
