Description

Modular concrete conveyor

The invention relates to a modular concrete conveying device, in particular for conveying and / or distributing fresh concrete. Furthermore, the invention relates to a pump module, a conveyor module and a supplementary module for a modular concrete conveyor.

Concrete conveyors are used to promote fresh concrete and / or distribute, for example, to be spent on construction sites to the respective component to be concreted or in a precast plant in each formwork to be concreted. For this purpose, a concrete conveying device usually has a pump which is designed to pump fresh concrete through a concrete pipe, which is usually at least partially flexible in order to achieve different components on a construction site or formwork sites in a precast plant. In a precast plant usually stationary concrete conveyor devices are in use, whereas on construction sites usually concrete trucks, such as truck-mounted concrete pumps, are used because they are only needed temporarily on the site. A concrete conveyor is usually fed with already mixed and spent on the concrete conveyor fresh concrete, which is then transported by a concrete pump through a concrete pipe to its final location.

The use of concrete conveyors is expensive, downtimes are therefore undesirable, but in particular in a precast concrete plant downtime is usually unavoidable: if all formwork that can be reached by the concrete conveyor is filled with fresh concrete, the time must be allowed for the concrete to harden sufficiently before the concrete is switched off and the finished parts are removed and new formwork for the next prefabricated parts is erected can.

It is therefore an object of the present invention to provide a concrete conveying device and / or modules therefor, which eliminate or at least reduce one or more of the disadvantages mentioned. Further, it is an object of the present invention to provide a concrete conveyor apparatus and / or modules therefor which reduce downtime and / or extend the field of application.

This object is achieved according to the invention by a modular concrete conveying device, comprising a pump module with a pump module line between a first pump module connection for a concrete supply and a second pump module connection for a concrete removal, a concrete pump arranged in the pump module line between the first and second pump module connection and a frame with a Base area corresponding to the footprint of a standardized ISO container, and having a height corresponding to a part, preferably one half, one or two thirds, the height of a standardized ISO container, a conveyor module with a conveyor module line between a first conveyor module connection for a concrete feed and a conveyor module interface for connecting a distributor device to the conveyor module line, wherein the conveyor module has a base area which corresponds to the base area of a standardized ISO container and has a height corresponding to a part, vo In other words, half, one or two thirds, corresponds to the height of a standardized ISO container, wherein the pump module line and the conveyor module line can be detachably connected to one another via the pump module connection for concrete removal and the delivery module connection for concrete supply.

Preferably, the conveyor module has a lifting device, which is designed to move the conveyor module interface in the vertical direction between a basic position and a high position. Further preferably, the conveyor module comprises a frame having a footprint corresponding to the footprint of a standard ISO container and a height corresponding to one part, preferably one half, one or two thirds the height of a standard ISO container , The concrete conveying device according to the invention is divided into two modules, a pumping module and a conveying module, and these modules are preferably arranged in frames or frame racks. All elements of the pumping module are preferably located within the frame so that the entire pumping module has a footprint corresponding to the footprint of a standard ISO container and a height corresponding to a portion of the height of a standard ISO container. In the pumping module, a concrete pump is arranged, which is designed to pump fresh concrete through a pump module line. The pump module line leads from a first pump module connection, through which concrete can be supplied to the pump module, to a second pump module end, from which concrete is discharged from the pump module. Preferably, the first and second pump module connection are arranged on opposite end sides of the frame of the pump module. Further preferably, the first and / or the second pump module connection are arranged on a side surface of the frame.

The conveyor module has a conveyor module line through which fresh concrete is also conveyed. The delivery module is disposed in concrete delivery devices downstream of the pumping module, so that the fresh concrete is conveyed through the delivery module by means of the pressure generated by the concrete pump of the pumping module. For this purpose, the delivery module has a first delivery module connection through which fresh concrete can be supplied to the delivery module. The conveyor module line connects to this first conveyor module connection and leads to a conveyor module interface, to which a distributor device can be connected. Such a distribution device can be, for example, a distributor arm which is designed to transfer the concrete conveyed with the concrete conveying device to various locations within a precast plant or to various components of a construction site. The first conveyor module connection is preferably arranged on an end face of the conveyor module. The conveyor module interface is preferably arranged on an upper side of the frame in the operating and / or transport state. Furthermore, the conveyor module has a lifting device with which the conveyor module interface can be raised from a basic position to a high position and lowered again. This movement between the home position and the up position has at least a vertical portion, and is preferably a movement in the vertical direction. With the conveyor module interface in the home position, all elements of the conveyor module are preferably arranged within the frame, so that the entire conveyor module corresponds to the dimensions of the frame. The high position of the conveyor module interface is preferably beyond the dimensions of the frame, ie in the high position, the conveyor module interface, preferably in the vertical direction, projects beyond the frame.

The standardized ISO container, to which the information on the base area and the height of the pumping module and the conveyor module are related, is preferably a 20 or 40 foot ISO high cube container. The frame of the pump module and / or the conveyor module preferably has connecting elements which are suitable for connection to other ISO containers and / or load securing elements and / or transport elements customary in ISO container transport.

The arrangement of both the pump module and the conveyor module in frame with the said, related to an ISO container dimensions, has the advantage that the pump module and the conveyor module are easily transportable and thus displaceable.

Since the pump module line and the conveyor module line are detachably connectable to each other via the second pump module connection for concrete removal and the conveyor module connection for concrete supply and this connection either directly, for example by connecting the frame of the pump module and conveyor module on their front sides, or by a compound only Connections with each other, for example by a flexible concrete pipe, it is possible to set up and operate the concrete conveyor in different constellations: The pump module and the conveyor module can be placed directly adjacent and their frames are interconnected, the second pump module connection for concrete removal and the conveyor module connection for concrete supply directly or for example via an adapter or adapter can be releasably connected to each other. In another constellation, the delivery module can be arranged spatially spaced from the pump module, so that the two frames are not connected to each other, but only the second pump module connection for concrete removal and the delivery module connection for concrete supply via a concrete line are releasably connected. In this way, the range of the concrete conveyor - can be significantly increased - regardless of a connected to the delivery module interface distribution arm. Furthermore, the concrete conveying device can thereby also be used at locations which do not have sufficient footprint for installation of a conventional concrete conveying device, since the contraction of the concrete conveying device into two modules for operating the concrete conveying device does not require a coherent footprint for the entire concrete conveying device, but rather two modules can be set up and operated separately from each other, and sound line is required. Due to the adaptation of the base area of the frame to a standard ISO container, the modules can be easily transported. This is further facilitated by the above-described preferably provided connecting elements. For the supply of mixed fresh concrete to the first pump module connection for concrete supply, for example, a fresh concrete storage or buffer storage may be provided, in which, for example, concrete transport vehicles discontinuously dispensed fresh concrete. By a sufficiently large dimensioning of the buffer memory, optionally with a mixing device for further mixing of the fresh concrete, it is possible to ensure continuous operation of the concrete conveying device even in the case of discontinuous delivery of fresh concrete. Preferably, this fresh concrete buffer storage is arranged in a frame whose base corresponds to the base of a standardized ISO container and whose height corresponds to a part or the entire height of a standardized ISO container. In this way, the buffer as well as the pump module and the delivery module can be easily transported and offset. The buffer memory preferably has an outlet for fresh concrete, which can be connected directly to the first pump module connection for a concrete supply of the pump module, via an adapter or connecting piece and / or via a supply line. The arrangement of pumping and conveying module in transportable frame has the advantage that such a concrete conveyor device can be used both in a precast plant and from there to a construction site for temporary use and from there can also be transported back to the precast plant. Due to the detachable connection of the pumping module and the conveyor module with each other, the two modules can be transported separately, for example, each on a truck, and connected to each other at the site. In this way, expensive downtime of the concrete conveyor can be avoided because stationary concrete conveyor devices can be replaced in precast plants with the modular concrete conveyor on the one hand and can be spent during the otherwise incurred in a precast plant downtime, for example, to a construction site. At the same time, the modular concrete conveyor device according to the invention can also replace concrete conveyor vehicles, such as truck-mounted concrete pumps, and has a much wider field of application than the concrete conveyor vehicles, since the modular concrete conveyor device according to the invention can also be operated in a precast plant, in contrast to a car concrete pump. A preferred embodiment of the concrete conveyor device is characterized by at least one supplementary module with a frame, with a base area corresponding to the base of a standardized ISO container, and with a height, the part, preferably half, one or two thirds, the height of a standardized ISO container, wherein the height of the frame of the supplementary module together with the height of the frame of the pump module and / or the frame of the conveyor module corresponds to the height of a standardized ISO container, and wherein the frame of the supplementary module detachably connected to the frame of the pump module and / or the frame of the conveyor module is connectable. In this further development form, at least one supplementary module is provided, preferably two, three or more supplementary modules are provided. If, in the following, a supplementary module is mentioned, the embodiments, features and advantages preferably also apply to two, three or more supplementary modules. Several supplementary modules can be the same or different. A supplementary module also has a frame whose base corresponds to a standardized ISO container and whose height corresponds to a part of the height of a standardized ISO container, preferably an ISO high-cube container. It is particularly preferred that the height of a supplementary module is selected so that the height of the supplementary module together with the height of the pump module and / or with the height of the conveyor module together corresponds to the height of a standardized ISO container. It is further preferred that the frame of a supplementary module also has connecting elements which are suitable for connection to other ISO containers and / or load securing elements and / or transport elements customary in ISO container transport and which are particularly suitable for the frames a supplementary module and a pump module and / or a conveyor module to connect with each other. If such a supplementary module is connected to the pump and / or the conveyor module, thus creating a combination that corresponds overall to the dimensions of an ISO container and thus can be transported as an ISO container. It is further preferred that in a combination of pumping module with one or more supplementary modules and / or delivery module and one or more supplementary modules whose height corresponds to the height of an ISO container, the frame of at least one of the modules of the combination and Connection between the modules of the combination are formed such that the combination has properties, in particular a rigidity, which correspond to the properties required for an ISO container, in particular a rigidity.

For example, one of the frame racks can be stiffened by means of transverse struts such that the combination of this stiffened frame with another frame for a combination with the dimensions of an ISO container meets the requirements for such an ISO container and thus a corresponding approval for the ISO container. Container transport receives.

In this way, it becomes possible to connect the pump module and / or the delivery module, which correspond in each case only to a part of the height of an ISO container, with further supplementary modules which can facilitate or improve, for example, the transport or operation of the concrete delivery device. It may also be preferred in particular to connect the pump module with two supplementary modules, in particular in a sandwich arrangement in which the pump module, in particular in the operating state, is arranged in the vertical direction between two supplementary modules and, together with these supplementary modules, corresponds to the dimensions of an ISO module. Containers corresponds. For such an arrangement, in particular a division into thirds, ie a height of one third of the height of an ISO container for the two supplementary modules as well as for the pumping module, is preferred. Since, in particular, interchangeability of the supplementary modules with one another is also preferred, the delivery module is preferably designed with a height of one, in particular two-thirds, the height of an ISO container, so that a supplementary module with a height of one third of an ISO container both with the pump module (and optionally with another supplementary module) or the conveyor module can be connected equally to a combination with the dimensions of an ISO container. Particularly preferred is an embodiment of the pump module with a height of one third of an ISO container and a conveyor module with a height of two thirds of an ISO container. In this way, in a direct connection, in particular the front sides of the pump module and the delivery module, different connection options: The pump module can be arranged flush with the top or bottom of the conveyor module, ie at the upper or lower half of the conveyor module. Therefore, it is preferable for the delivery module to have, in addition to the first delivery module connection for a concrete supply, a second delivery module connection for a concrete supply, wherein the two delivery module connections are arranged such that the first delivery module connection is arranged on the pump module connection for a concrete removal can be when the pump module is connected to the lower half of the conveyor module and the second conveyor module connection can be connected to the pump module connection for a concrete removal, when the pump module is arranged on the upper half of the conveyor module. In a preferred embodiment, at least one of the supplementary modules is designed as a transport module and is arranged in an operating state and / or a transport state below the pump module and / or the conveyor module. Such a transport module preferably has a drive unit and / or a chassis and / or a steering device. When the pump module and / or the conveyor module is placed on such a transport module or be, the pump module and / or the conveyor module can be easily moved by means of the transport module or the transport modules. A self-propelled transport module with a drive unit, a chassis and a steering device can thereby, for example remotely controlled, independently move a pump module and / or conveyor module. If a transport module has only one chassis and, for example, a coupling unit for coupling to a transport vehicle, the transport module can act as a trailer and be moved together with the attached pump module and / or conveyor module by a vehicle or a self-propelled transport module. Depending on the substrate on which the combination of pumping module and / or conveying module plus supplementary module is to be moved, the chassis can also be designed as a track, so that the transport module can be moved in the sense of a crawler with a tracked chassis.

It is also particularly preferred that at least one of the supplementary modules is designed as a recycling module for the treatment of residual concrete. In particular, when using the concrete conveyor in a precast plant regularly accumulating residual concrete quantities are to be disposed of at the beginning and end of a concreting process. However, the fresh concrete to be disposed of as residual concrete has due to the properties of its constituents and their interaction so-called solidification and hardening properties. Solidification is the transition of fresh concrete from a flowable, plastic state to a solid state due to the hydration of the cement paste. Through continued hydration, the concrete hardens, ie it acquires a certain concrete compressive strength. Due to this solidification and hardening property, fresh concrete must be promptly removed from all used tools equipment and concrete conveyors or pump piping. Since only a certain time window lies between the mixing of the concrete and the onset of hardening or hardening, only a limited period of time remains after the processing of the concrete as intended in order to dispose of the residual concrete. Therefore, it is preferred that residual concrete can be processed directly on site to save transport times and costs.

It is therefore particularly preferred that a supplementary module is designed as a mobile concrete recycling plant comprising a residual concrete treatment device, which processes the residual concrete so that it loses its solidification and / or hardening property. In particular, it is preferred that such a mobile concrete recycling plant and disposed therein residual concrete processing device of the recycling module as in the utility model application of the applicant from 10 August 2012, including the training described therein is formed.

A climate control may include in particular a ventilation and / or cooling. Both climate control and sound absorption are particularly advantageous in combination with the pump module. Such a climate control and / or sound attenuation module can preferably be arranged on the pump module. In this way, a further supplementary module, in particular a transport module can be arranged under the pumping module.

A further preferred embodiment is characterized by a manifold module having a manifold, the manifold having a manifold interface for connection to the manifold interface (22), a discharge port for delivering concrete, and a manifold between the manifold interface and the discharge port, and wherein the manifold module is preferably has a footprint corresponding to the footprint of a standardized ISO container and a height (203) corresponding to a part, preferably one half, one or two thirds, the height of a standard ISO container. In another preferred embodiment provided that at least one of the supplementary modules is designed as a distributor module with a distributor device, wherein the distributor device has a distributor interface for a connection to the conveyor module having cut portions, a discharge port for discharging concrete and a distribution line between the distribution interface and the discharge opening.

The distributor is provided with a manifold interface through which a connection to the conveyor module interface can be made so that concrete from the conveyor module line can be pumped into a distribution line. The distribution line ends in a discharge opening for the delivery of concrete, which may for example be the open end of such a distribution line or may still be provided with a corresponding dispensing element.

It is further preferred that the distributor module or the distributor device is movable between a transport position and a distributor position, wherein the distance between the distributor interface and the dispensing opening in the distributor position is greater than in the transport position. Preferably, by means of a distributor drive, the distributor module or the distributor is movable between a transport position and a distributor position, that in the transport position all elements of the distributor module or the distributor are arranged within the frame of the supplementary module and in the distributor position, however, at least the discharge opening from the frame protrudes, preferably over several meters. In particular in combination with a distributor module, the advantage of the lifting device of the conveyor module becomes clear: Since the conveyor module interface can be moved in the vertical direction to a high position with the lifting device, a distributor interface arranged at the conveyor module interface is also moved upward, so that the distributor device, which is arranged at this distributor interface is also moved vertically upwards. This extends the range of the dispensing opening of the distributor.

Particularly preferred is a design of the distributor module or the distribution device as a scissors lever construction, wherein the distribution line preferably along at their respective end points interconnected scissor levers. In contrast to existing distributor arms here a scissor lever construction is provided as a distributor module or the distribution device with several intersecting scissor levers in the sense of a Nuremberg scissors. The distribution line preferably runs on a scissor lever train zigzag to the discharge opening, which is preferably arranged at the end of one of the last two scissor levers. The design as a scissors lever construction has the advantage that an actuator rail, which connects the two free ends of the first scissor lever with each other and varies over a variation of the distance of these free ends of the first two scissor levers, the total length of the scissor lever construction and thus the range of the distributor module or the distributor can be arranged in the distributor module and secured there accordingly, whereas the end of the scissor lever construction with the discharge opening can be substantially free of drive devices for moving the Scherenhebelkon- construction.

Furthermore, it is preferred that at least one scissor lever is designed as a truss bearer.

Preferably, all scissor levers are designed as lattice girder, preferably, however, at least all those scissor levers which carry the distribution line for conveying the fresh concrete, the training as truss girder makes the scissor lever light and stable at the same time.

Furthermore, it is preferred that the scissors lever construction is arranged and configured such that the dispensing opening is movable both in the horizontal and in the vertical direction. Such a variable possibility of movement of the scissor lever construction facilitates the movement of the fresh concrete also to remote components or formwork. For this purpose, in particular, an actuator rail connecting the two free ends of the first two scissor levers is rotatably and / or pivotably arranged about one, two or more axes in the distributor module. Furthermore, it is preferred that a counterweight of the distributor device is arranged and configured such that the counterweight is located in the transport position and / or in the distributor position within the base area of the distributor module.

In this way it is possible to prevent concrete from escaping from the discharge opening before or after concreting.

A further preferred embodiment of the concrete conveying device is characterized by at least one supplementary container whose dimensions correspond to the dimensions of an ISO container, with a supplementary line passing through the supplementary container in the vertical direction and a staircase arrangement and other logistics components.

The free space of the supplementary containers remaining next to the supplementary line can preferably be used by means of a staircase arrangement, so that the combination of pump module, delivery module and supplementary containers can at the same time also serve as a staircase for the construction site facility. Further remaining space in the supplementary containers can be used, for example, as a work surface, as open areas, eg for formwork preparation, as a storage area for system components of the formwork, or closed for recreation rooms for construction site personnel in the immediate vicinity of the site in the building. Here also elements for receiving a freight elevator can be provided. Also, the supply and disposal lines for the construction phase can be pre-installed here.

The actuator rail 920 is rotatably supported about the axis 921. In addition, the actuator rail 920 can also be rotatably mounted about one or more further axes, in particular axes orthogonally arranged to the axis 921. Further, preferably, the first guide lever 902a is variable in length via an actuator 912a to further increase the moving space of the scissor lever structure 900. In addition, in FIG. 1 two further supplemental modules designed as transport modules 300b, c are shown, which can be connected to the pump module 100 and / or the conveyor module 200 instead of the recycling module 400 or the transport module 300a. The transport module 300b is designed as a trailer with rollers 310b and a coupling device 31 1 b, with which the trailer can be connected, for example, with a designed as a self-propelled transport module 300a transport module.

Such an arrangement is particularly preferred in a precast plant. If now in the precast plant more remote areas are to be supplied with fresh concrete, the connection between the pump module 100 and the conveyor module 200 and optionally the supplementary modules 400 and 300a can be solved. Subsequently, the pumping module 200 can be moved, for example, on the self-propelled transport element 300a within the precast plant. Incidentally, when the pump module port for a concrete discharge is connected to the concrete module port for concrete supply by means of a flexible concrete pipe, the operability of the concrete conveyor device 1 is maintained although the conveyor module 200 has moved away from the pump module 100 by means of the transport module 300a.

For use on a construction site, the pumping module is preferably also used instead of on a recycling module 400 on a transport module 300a, b, c arranged to be flexibly movable on the construction site. Particularly preferred for use on construction sites is a transport module 300c with tracked chassis 310c.

FIGS. 2 to 4 show a supplementary container 800 for vertical construction site logistics with a frame 801. The supplemental container 800 and its frame 801 preferably correspond to the dimensions of a standard ISO container. The frame 801 has connecting elements 802 which are suitable for connection to the frames of the remaining modules (101, 201, 301a, b, c, 401, 501, 701) or for connection to other ISO containers and / or in the ISO Container transport customary Ladungssicherung- insurance elements and / or transport elements are suitable. Furthermore, the supplementary container 800 has a supplementary line 810 passing through in the vertical direction for the passage of fresh concrete. Preferably, a pump module 100 is arranged below the supplementary container 800 and a delivery module 200 above the supplementary container 800, wherein the supplementary line 810 serves, if necessary, to connect the second pump module connection for a concrete removal with the first delivery module connection for a concrete supply with further connecting lines. The supplementary container 800 further has a stairway arrangement 820, which is particularly preferred if a plurality of supplementary containers 800 are to be arranged one above the other between a pumping module 100 and a conveyor module 200. The remaining area 830 in the supplemental container 800 for the vertical construction site logistics can be used as a working area, e.g. as open areas e.g. for formwork preparation, as storage area for system components of the formwork, or closed for recreation rooms for construction site personnel in the immediate vicinity of the site in the building. Here also elements for receiving a freight elevator can be provided. Also, the supply and disposal lines for the construction phase can be pre-installed here.

FIGS. 6A-F show a further embodiment of a concrete conveying device 1000, in FIGS. 6A and 6B in a transport position, and in FIGS. 6C-F in different views in a distribution position. The conveying device 1000 has a plurality of modules 1 100, which are preferably designed as a basic module and supplementary modules. However, in FIGS. 6A-F, the modules 1100 are shown, with the exception of a residual concrete recycling plant 1400, without further associated elements. However, it can be seen cross bracing to increase the rigidity of the frame of the modules 1 100.

The conveyor module 1200 further includes a conveyor module line 1220 between a first conveyor module port 1230 for a concrete feed and a conveyor module interface 1310 for connecting a distributor.

To the interface 1310, the distribution device of the distribution module 1300 is connected. The distribution module 1300 has, in addition to the actual distribution device, a discharge opening 1320 for dispensing concrete and a counterweight 1330. The counterweight 1330 is arranged such that it is arranged both in the transport position and in the distribution position, in particular also when rotating the distributor, within the base of the conveyor or distributor module.

It can be seen in FIGS. 6A and 6B that, in the transport position, the conveyor module 1200 is arranged on a module 1100 and the distributor module 1300 is arranged on the conveyor module 1200. The delivery module 1200 is connected to the distribution module 130 via the delivery module interface or distribution module interface 1310. The distributor module 1300 projects beyond the two further modules 1 100. Overall, this results in an expansion of the conveying device 1000 whose base area corresponds to the base area of two modules 1100 and whose height corresponds to the height of three modules 1100, since preferably also the distributor module in the transport position has the height of a module 1100. Preferably, the total height of the conveyor 1000 corresponds to the height of a standardized ISO container. In this way, a transport, for example, on a truck is possible.

In the distribution position shown in FIGS. 6C-F, the delivery module 1200 with the distribution module 1300 has been arranged on the two modules 1 100 already arranged one above the other. In this way, can be distributed with the distribution device via the discharge port 1320 from the elevated position concrete. FIGS. 7A-E show a height-adjustable frame 2000 with two sub-frame pieces 2100, 2200 connected via connecting elements 2300. In Figs. 7A and 7B, the frame 2000 is shown in the extended position, in Figs. 7C and 7D in the shortened position, and in Fig. 7E in a plan view. The two partial frame pieces 2100 and 2200 can be releasably fixed to one another via the connecting elements 2300 both in the shortened and in the extended position. In particular, on the partial frame piece 2200 further connecting elements 2300 are preferably provided, which can be used to connect the frame 2000 with other elements.

FIG. 8 shows a preferred embodiment of a closure 3000 of a delivery opening of a distribution device of a distributor module. This closure 3000 has a flexible tube extending between a first end portion 3100 and a second end portion 3200. At the first end portion 3100 may be provided a connector for connecting the shutter 3000 to the discharge port of the distributor. The flexible hose can be connected, for example via pipe clamps with the connector. In Figure 8, the closure 3000 is shown in the closed position in which the second end portion is releasably secured via the eyelet 3210 to the first end portion disposed hook 31 10 such that gravity-induced dispensing of concrete through the tube is prevented. In this way, the discharge opening of a distribution device can be closed easily and safely. Furthermore, the training as a flexible hose has the advantage that such a tube is inexpensive to manufacture and therefore can be easily replaced.
