Description

Technical Field

[0001] The present invention relates to a method for carrying out engineering measures, in particular deep engineering measures, on a construction site with a certain number n of engineering machines, in particular deep engineering machines, wherein attached parts, in particular engineering tools, are detachably and replaceably arranged on the engineering machines, wherein a certain number N of attached parts are stored at the construction site, wherein N>n>2.

[0002] The present invention also relates to a component for performing engineering measures, in particular deep engineering measures, on a construction site with a certain number n of engineering machines, in particular deep engineering machines, wherein attached parts, in particular engineering tools, can be detachably and replaceably arranged on the engineering machines, wherein a certain number N of attached parts are stored at the construction site, wherein N>n>2. Background Art

[0003] When carrying out engineering measures, it is often necessary to place various engineering tools on construction machinery, such as drilling equipment, during the work process. For example, with drilling equipment, drilling a hole in normal soil may require the use of a drilling screw, which allows for efficient and rapid drilling in normal soil conditions. When the soil layer changes, such as when reaching rock formations, it may be necessary to replace the drilling screw with a rock drill bit, or to use a box drill bit when reaching gravel layers. It is known to provide each engineering tool with an identification device so that it can be automatically recognized by the machine. The machine may include a detection device, such as a transmitter and receiver, that queries the identification device of the attached engineering tool via wired or wireless communication. This allows the machine operator to reliably determine which engineering tool is currently installed. However, not all engineering tools are always equipped with such an identification device, or the identification device may not function properly. Furthermore, particularly when querying via radio, other engineering tools in the vicinity may negatively impact the one-to-one correspondence.

[0004] Information about the individual construction machines can be retrieved from the central device, namely which engineering tool is currently in use at the construction machine. This information is important for workflow planning at the construction site, as it is necessary to determine which engineering tools are still available and can be used by other construction machines at the construction site.

[0005] However, for reliable work planning, simply knowing the engineering tools currently installed on the construction machine is not enough. This is because, when operating a construction machine to perform a specific engineering task, the construction machine typically also uses other engineering tools that, while not currently installed on the construction machine, are located in its immediate vicinity and require tool replacement within the foreseeable future. Consequently, a group of multiple different engineering tools can actually be used by a single construction machine.

[0006] It is known that construction machine drivers inform construction management which set of engineering tools is required at the construction machine and is therefore not actually available for use, even though individual engineering tools are not installed at the construction machine. However, when the construction machine driver makes this notification, it can happen that he or she does not inform construction management of the actually required engineering tools, does not fully inform, or incorrectly informs construction management of the engineering tools actually required, or inadvertently fails to inform or incorrectly informs that individual engineering tools are available after completing an engineering measure. This makes efficient construction management and the efficient storage of necessary engineering tools difficult under workflow control at the construction site. Summary of the Invention

[0007] The present invention is based on the object of specifying a method and a device with which particularly efficient implementation of engineering measures at a construction site is possible.

[0008] This object is achieved on the one hand by the method according to the invention and on the other hand by the assembly according to the invention. The invention has a number of preferred embodiments.

[0009] The method according to the invention is characterized in that the number n and types of construction machines present at a construction site and the number N and types of attachment parts are stored in a computer unit, which is data-connected to each individual construction machine and queries information about the actuators of each individual construction machine, and the computer unit determines which attachment part is installed on the individual construction machine based on the information obtained, and the computer unit determines and indicates which attachment parts are freely available at the construction site.

[0010] The basic idea of the present invention may be to provide a method in which the engineering tools actually installed on a construction machine can be reliably determined by a computer unit. The computer unit queries information about the actuators of each individual construction machine, for example, information from the drive system, rotary drive, linear actuator, and information about the positions of components of the construction machine, such as struts, drilling rotary drives, booms, etc. The computer unit is configured to determine which engineering measures the construction machine has performed based on this information and, based on information stored in a database, determine whether and which engineering tools the construction machine is using. This information can be used alone or in combination with other information to determine the engineering tools used and installed. In this way, the computer unit can essentially automatically determine which engineering tools are actually in use by each individual construction machine. By comparing with a pre-set inventory of engineering tools, it can determine which and how many engineering tools are actually available for use at the construction site.

[0011] This allows to avoid idle times at the construction site due to a shortage of construction tools at the construction machine and also an overstocking of construction tools, which results in significant cost savings.

[0012] An advantageous embodiment of the invention can provide that the computer unit determines, based on the information obtained, which set of attachment components is required for the individual construction machine. A method is provided in which the computer unit can determine not only the engineering tools actually installed on the construction machine, but also the one or more additional engineering tools that the respective construction machine will immediately need in order to carry out the engineering work.

[0013] In principle, the attachment currently installed at the engineering machinery can also be manually input into the control system by the machine driver, so that the attachment can be queried by the computer unit. Preferably, according to an expansion scheme of the present invention, each engineering machinery has a detection device, which detects which attachment is placed at the engineering machinery and / or in the vicinity. Here, the detection device can be a camera system or a transmitting and receiving device. The detection device can preferably only detect the tools directly placed at the engineering machinery. However, it is also possible to detect engineering tools in the vicinity of the machine, but in this case, it is impossible to reliably and one-to-one determine whether an engineering tool is actually needed for the engineering machinery or whether the engineering tool has been installed at the engineering machinery. This information is used in combination with other information for the actuator to reliably determine the required and free engineering tools. Therefore, the computer unit can check and verify the determination made based on the actuator information of the engineering tool placed and used by the additional information for the engineering tool.

[0014] Particularly preferably, the attachment component is provided with a machine-readable identification device. The machine-readable identification device on the attachment component can be, for example, an RFID chip that can be wirelessly interrogated. This identification device allows for a direct response signal upon receiving a corresponding interrogation signal. This response signal can contain the necessary information specific to the interrogated attachment component. In principle, other identification devices can also be used.

[0015] Another preferred embodiment of the present invention provides that the computer unit stores for each construction machine the following information: which set of attachments is used to perform which construction measure, and what information is expected for the actuators of the construction machine in this regard. For example, when constructing foundation piles using a drilling rig, specific attachments, such as kelly bars, drilling tools, and, for example, tools for cleaning the bottom of the drill hole, must be used simultaneously or alternately. These attachments must each be operated at specific speeds and feed rates.

[0016] For example, the position of the rotary drive along the support rod can be used to determine when a component, such as a tool for cleaning the bottom of a drilled hole, is needed. This can be taken into account by a computer unit, which can be located in the central system, to release the attached component or to reserve it for further use by the construction machine. If necessary, the central computer unit can also trigger the procurement process for one or more additional attached components to be delivered to the construction site. It can also indicate to the construction management which attached components are no longer needed for other engineering measures at the construction site and can be removed from the site.

[0017] According to the present invention, another preferred method variant comprises providing at least one position determination device, which determines and outputs the position of the construction machine and / or the attached component on the construction site. This allows for precise position determination of each individual construction machine and each individual attached component. Thus, in the case of free construction tools, the appropriate construction tool can be assigned to the construction machine, with the two being as close together as possible. This allows the transport process to be kept confined to the construction site, further increasing the efficiency of the engineering work to be carried out.

[0018] The position determination can take place via a GPS system or a position determination system within the construction site, wherein the individual machines and components can be equipped with corresponding transmitting and / or receiving devices for transmitting / receiving position signals.

[0019] In principle, all conceivable construction machines can be provided as construction machines. For deep-drilling work, these can include, in particular, drilling rigs, grabbers, slotted wall milling machines, excavators, cranes, etc. Attached components are preferably deep-drilling tools, in particular drilling screws, rock drill bits, drill buckets, or pumps or drilling tools. Other deep-drilling tools and other engineering tools are also generally possible.

[0020] The component for performing engineering measures according to the present invention is characterized in that a computer unit is provided, in which the number n and types of engineering machines present at the construction site and the number N and types of attachment parts can be stored, the computer unit is in data connection with each individual engineering machine and is configured to query information for the actuator of each individual engineering machine, the computer unit is configured to determine which attachment part is placed on the individual engineering machine based on the information obtained, and the computer unit can determine and indicate which attachment parts are available for free use at the construction site.

[0021] In particular, the above-described method can be carried out using the described component, thereby achieving the above-described advantages.

[0022] According to a further development of the present invention, the computer unit is advantageously configured to determine, based on the acquired information, which set of attachment components is required for each individual construction machine. The computer unit can thus determine not only the engineering tools actually installed on the construction machine, but also the one or more additional engineering tools that the respective construction machine will immediately require to perform the engineering measure. This simplifies and improves work planning.

[0023] In this case, it is particularly preferred that each construction machine has a detection device that can detect which attachment component is attached to the construction machine and / or which attachment component is in the vicinity. In particular, the detection device can be a transmitter and receiver for wirelessly querying the attachment component. The additional information thus obtained can be used to verify the identification of the attached construction tool.

[0024] According to a further development of the invention, each attachment part is preferably provided with a machine-readable identification device. The identification device can in particular be an RFID chip, which is placed at a suitable location on the attachment part.

[0025] By linking multiple sensor information from different attached devices and comparing movements such as rotation, acceleration, or tilt, the machine can infer from the sensor information which attached device is connected to which other component and which component is ultimately connected to the device. To do this, the machine compares the motion information from these sensors with information from the machine's actuators.

[0026] For example, after installing a kelly and drilling tool, the machine rotates the attached components at a specific speed. By comparing the rotation rates of all considered components, the machine eventually detects the components it has installed and ultimately prevents them from being accessed by other machines.

[0027] By means of the rotational position or orientation of the attachment component, for example a box drill bit (vertical, horizontal), the machine can already distinguish which tool is actually intended for attachment.

[0028] The basic idea of the present invention is not limited to identifying which engineering tool is installed, but rather it is possible to identify which components are still available based on the installed or connected components / attachment parts.

[0029] This is important for the engineering process because it allows tools to be used more efficiently. Tools can therefore also be tracked. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The invention will be explained in more detail below with reference to a preferred exemplary embodiment. The single figure shows a schematic top view of a construction site with a plurality of construction machines and attached components. DETAILED DESCRIPTION

[0031] The single figure schematically illustrates a construction site 5 with an assembly according to the present invention for carrying out engineering measures. For example, three construction machines 10 are provided, each equipped with a detection device 12 for detecting attached components 20. Attached components 20 are, in particular, construction tools equipped with an identification device 22. Identification device 22 can, in particular, be an RFID chip that can be interrogated by radio via detection device 12 of construction machine 10.

[0032] In this case, the detection device 12 can be part of a control unit of the respective construction machine 10 , wherein this control unit is also in a wireless data connection with the central computer unit 8 .

[0033] At least one attachment part 20 is mounted on each construction machine 10, for example, to carry out a specific engineering measure or a specific engineering work step. Furthermore, further attachment parts 20 are stored at the clearing location 6 or in the vicinity of the construction machine 10. These attachment parts 20, not directly mounted, are provided for rapid replacement at a specific construction machine 10 in order to carry out an engineering measure for which a specific sequence of work steps with different engineering tools or attachment parts 20 is provided. A computer unit 8 is data-connected to each individual construction machine 10, wherein information regarding the actuators of each individual construction machine 10 is queried. Based on the information obtained, the computer unit 8 determines which attachment part 20 is mounted on the individual construction machine 10. This data can be compared and checked with data from a detection device. This also allows the determination of which attachment parts 20 are in the vicinity but not mounted on the construction machine 10.

[0034] Furthermore, further free attachment parts 20 can be provided on the tool magazine 9 , which are essentially freely available.

[0035] All attachments 20 on the construction site 5 are listed in the central computer unit 8 in a number N. Similarly, the number n of construction machines 10 on the construction site 5 is stored in the central computer unit 8. By querying the actuator information and the detection device 12 via the associated control unit of each construction machine 10, the central computer unit 8 can determine which specific attachment 20 is installed on the construction machine 10. Preferably, the computer unit 8 can also determine which other attachments 20 are located in the vicinity of each construction machine 10. However, since the individual construction machines 10 are arranged close to one another, this information is generally insufficient to determine which attachment 20 in the vicinity of a construction machine 10 is assigned to that construction machine and is also needed by that construction machine at a later time, or is possibly already located on the construction machine 10.

[0036] For each engineering measure, the required engineering tools or attachments 20 and their sequence, as well as data representative of the actuators used when the corresponding attachments 20 are used on the construction machine 10, are stored in the computer unit 8. The central computer unit 8 can thus determine or verify which attachments 20 are currently in use and which attachments 20 not yet installed on the construction machine 10 are required by the construction machine 10 at a later time and are therefore reserved for it and not freely available. By comparing this with the overall list of attachments 20 available, the computer unit 8 can determine which attachments 20 are actually freely available on the construction site. This can be taken into account by construction management when planning work or when purchasing or releasing attachments 20.

[0037] Information about the actuators of the construction machine 10, i.e., information about the vertical feed, the adjustment position of the actuating cylinders and drives, the rotational speed, and other information about the machine's sensors, can be wirelessly queried from the central computer unit 8 via the machine controller 14 at the construction machine 10. Within the meaning of the present invention, the term "actuator" is to be understood as an adjustable and / or movable component of the construction machine 10 that is activated in order to carry out a construction measure together with the attached component 20.

[0038] In addition, the number and type of attachment parts 20 stored there and essentially freely available can also be detected by the central computer unit 8 using a detection device (not shown) at the tool magazine 9. The current operation of each construction machine 10 can preferably be determined by the central computer unit 8, and the need for specific attachment parts 20 can be determined quickly or even in real time. This allows attachment parts 20 to be reserved in the tool magazine 9 or further attachment parts 20 to be released at the construction site 5.

[0039] Furthermore, the construction machine 10 and the attached components 20 can be provided with a position determination device, so that the specific position of the construction machine and the attached components on the construction site can be determined. This position can then be displayed on a screen in the central computer unit 8 or in each construction machine 10 as a position plan, as shown in the figure, for example.
