It is preferably provided that the at least one drilling device and the gap devices are arranged movably on a device carrier. For this purpose, the device carrier preferably comprises at least one guide rail along which the at least one drilling device and the gap devices are movably guided.

In this way, for example, the control of the device is facilitated, since the one-dimensional guide a single position information is sufficient to determine the position of a cleavage device and / or a drilling device or set. Due to this one-dimensionality, the splitting device must be centered with respect to a bore only along one degree of freedom.

In order to determine the movement system, the device carrier is preferably position-centered relative to the solid material via a centering device connected to the device carrier. Preferably, a plurality of centering means are provided, which are applied or pressed against the solid material in order to determine the position of the device carrier relative to the solid material.

It is preferably provided that the production of the holes and the splitting by the cleavage devices happen with position-centered device carrier. This means, in particular, that during the execution of the separation process, the equipment carrier remains stationary with respect to the solid material.

It is preferably provided that in a first step, one or more bores of a drilling arrangement provide a plurality of bores in the solid material. The holes correspond to holes that are at least designed as a blind hole or enforce the solid material entirely. The holes are preferably provided along a drilling contour. As a result, a series of spaced bores in solid material is created, along which should also be the cutting of the solid material. Drilling is provided at predefined or user selectable drilling locations.

It is preferably provided that in some of the holes, but not in all holes, in a further step, the gap extensions of the gap devices are introduced. By expanding the gap extensions, a pressure can be exerted on the inside of the holes, which leads to a fracture of the solid material along the drilling contour, whereby the solid material is cut. In all embodiments, the gap direction of the gap devices is preferably normal to the drilling contour, so that the solid material can be split along the drilling contour.

To simplify the operation and to partially automate the method, the device preferably comprises a control device. This control device preferably comprises a data memory for storing position data of the at least one drilling device and / or the drilling locations. By means of this control device, the position of the bores, and in particular the position of the drilling points, can be stored as position data in the data memory.

It is preferably provided that the at least one drilling device and the gap devices are provided on a device carrier. The gap devices and the at least one drilling device are preferably arranged side by side along the device carrier. In particular, the at least one drilling device and the gap devices are arranged side by side on a guide rail. In all embodiments, the guide rail may comprise a rail-shaped carrier or a plurality of guide rail-like carriers, on which guide devices of the gap devices and the at least one drilling device are guided. By means of this rail-like guide, all degrees of freedom are preferably blocked except for the degree of freedom running along the drilling contour or the degree of freedom running parallel to the drilling contour. As a result, the gap devices and the at least one drilling device can be moved along the drilling contour.

Optionally, not all holes are provided along the drilling contour. In this case, for example, a plurality of holes may be provided, with only some of these holes along the drilling contour. In this case, the device carrier is not during all steps to be performed over the centered solid material. However, at least for the last steps, in which holes are created, in which the gap extensions of the cleavage devices are introduced in a further step, the device carrier, however, is position-centered relative to the solid material, so that facilitates the insertion of the gap extensions of the cleavage devices in the holes and in particular can be partially automated.

In all embodiments, the position centering of the device carrier can be effected by a combination of at least one centering element and the stationary positioning of the tool carrier of the working device.

In all embodiments it can be provided that the drilling device, in particular the drill, comprises two actuators which can be actuated separately from one another for the movement of the drill along the drilling axis. In particular, a drive is set up or suitable for effecting delivery of the drill to the solid material. The second drive is set up or suitable in particular for creating the bore.

According to a preferred embodiment, the splitting device is movable along the gap axis via two drives, which can preferably be actuated independently of one another. The one drive is set up or suitable in particular for feeding the slitting device in the direction of solid material. The second drive is used to insert the gap extension in the bore.

• In einem ersten Schritt wird die Vorrichtung, insbesondere der Geräteträger, gegenüber dem festen Material positioniert, platziert und/oder lagezentriert.

According to an exemplary embodiment, the method of dividing solid material may include the steps of:

• In a first step, the device, in particular the device carrier, positioned relative to the solid material, placed and / or position-centered.

In a further step, the mode of the drilling operation can be selected. For example, a conjunctive operation and / or a parallel operation is possible.

In conjunctive operation, two drilling devices can start at outer positions of the equipment carrier with the creation of two holes. In a further step, the drilling devices are pulled out of the holes created and moved in the direction of the center of the device carrier in order to create further holes. Through this Conjuntionsbetrieb the holes are thus created from outside to inside. In parallel operation, however, the drilling equipment can be moved from one side of the equipment carrier to the other side of the equipment carrier to create several holes along the drilling contour step by step.

In particular, in the production of several holes along a relatively long drilling contour, it is advantageous that the holes are made symmetrically along the equipment carrier. For example, it can be started in conjunction operation with longer drilling contours, wherein the one drilling device is in one end region of the equipment carrier and another drilling device is arranged at the opposite end region of the equipment carrier to create two spaced-apart holes. In a further consequence, the two drilling devices can be moved in conjunctive operation to one another and in particular to the center region of the device carrier, bores being produced at specific intervals.

If necessary, it is possible to switch over to parallel operation in the middle area. During parallel operation or when switching to parallel operation, one of the two drilling devices moves automatically or partially automatically into the vicinity of the other drilling device. In the course of the two drilling devices are moved parallel to each other to produce at certain intervals further drilling. Such a parallel operation in the central region is particularly useful when a gap device is provided between two drilling devices along the device carrier. Due to structural factors, it is not possible in many cases, to position two drilling devices arbitrarily close to each other. In particular, the minimum distance between two drills of two drilling devices is greater than the desired distance between the holes. If now two drilling devices are moved exclusively in conjunctive operation in the direction of the center, an area remains over exactly in the middle, which would then have to be provided with further bores by a single drill in order to complete the desired drilling pattern. A more efficient method is to switch to parallel operation after a certain progress, for example at a distance of approximately one to one and a half meters in the conjunctive operation, and to create the remaining holes in the center region of the equipment carrier in parallel operation.

Simultaneously with the choice of the drilling operation or after the choice of the drilling operation, a specific drilling grid or a drilling pattern can be selected. In this case, for example, the distances between the holes along the drilling contour can be determined and determined. Example spacings range from about 100 mm to about 250 mm or more. The choice of the drilling operation and the choice of Bohrrasters done in particular via an input to the control device.

In a further step, the automated or semi-automated drilling process can then be started. In this case, position data of the drilling devices are determined in particular via one or more position sensors and preferably stored in a data memory. Once the desired holes have been made, the drills of the drills are removed from the boreholes. Subsequently, the cleavers are transported to the wells or to the desired wells. In this case, a collision protection can be given by the control devices. This collision protection serves to ensure that the splitting devices do not collide with each other and not with the drilling devices. Furthermore, this also preferably prevents a collision of the drilling devices with each other. In particular, safety distances between the individual components can be detected via the position sensors.

In a further step or simultaneously, the cleavage devices can be selected for cleaving the solid material. For example, three slit devices are provided. About check valves, for example, a control of the gap devices happen, whether they are actively used to split the solid material, or whether they remain inoperative.

In particular, a choice of the splitting devices can be made by input to the control device. In a further step, the selected cleavage devices can then be assigned to individual holes. This is done, for example, by selecting a number of a hole or by manual delivery in the vicinity of the desired hole. In this case, each splitting device can preferably be positioned individually and independently of the others.

In a further step, the splitting process can then be started. In this case, the splitting device is preferably positioned automatically or partially automatically via or in the respective bore. This is in particular stored on the Location data used. In addition, a position sensor or a plurality of position sensors for positioning the gap devices can be used. For example, in the case of manual delivery, the respective splitting devices can be automatically moved to the nearest borehole.

In a further step, the splitting device or its gap extension is preferably introduced into the borehole until a switch-off pressure is reached.

In a further step, the gap extension is preferably actuated until, for example, a certain cut-off pressure has been reached. A possible cut-off pressure of an exemplary embodiment of a splitting device is, for example, between 400 and 600 bar, preferably about 500 bar.

In a further step, the cleavage devices can be removed again from the boreholes. Optionally, a separation of the solid material is already carried out, whereby the device can be removed and positioned at a new desired location and in particular position-centered.

The invention will now be further described by way of an exemplary embodiment.

• The device according to the invention installed on a working device 2 designed as a hydraulic excavator is provided with rotary hammers which drill the borehole and with splitting devices which split the stone after the drilling operation. The number of drilling and splitting units is variable. It is preferably provided that each hammer drill and each splitting device can be moved with a separate drive 19 together with brake device by engagement with a rack on the equipment carrier 4 and can be moved by means of cylinders along the drilling or slit axis. First of all, the series drilling machine is positioned on the rock to be excavated by means of an excavator and the functions of turning, swiveling and tilting the series drilling machine. Depending on the circumstances, the carriage 17, on which the hammer drill is installed, can be individually positioned. Afterwards you can choose between conjunction operation and parallel operation. Furthermore, the drilling distance between the to be drilled Holes between, for example, 100 - 250mm in 50mm increments are defined and set. Once the data has been selected, the drill pattern can be drilled in manual or automatic mode.

The position of the individual carriages 17 or splitting devices, which are mounted on separate frames and can individually move on the equipment carrier 4, is detected by an inductive measuring system according to this embodiment. About a magnetic bar, the respective position of the individual rotary hammer and / or splitting device is queried and checked. Further, if necessary, a system for the drilling and splitting unit is provided, which queries the individual positions of the control device. So they can always communicate with each other and always dodge in the process of the individual drilling devices 14, cleavers 10, carriages 17 and / or frame to avoid a collision. In addition, all positions of the boreholes can be stored for subsequent automatic positioning of the splitting cylinder. After drilling, the number of splitting devices or splitting device can be selected. The activation (activation / deactivation) of the individual splitting cylinders preferably takes place via individual shut-off valves. Then the respective splitting device is driven in particular manually in the approximate gap position. If the splitting operation is started, the respective splitting device moves automatically or partially automatically to the nearest, stored borehole and starts the splitting process. The displacement of the splitting cylinder corresponds to the maximum Verschubweg the carriage 17 of the drilling unit - in particular to achieve the maximum lower gap position with non-planar block surface. The splitting wedges of the splitting device 10 are preferably provided with a centering bevel in order to enable easier positioning in the borehole. Furthermore, the splitting cylinders are preferably mounted on a special rubber mount to compensate for inaccuracies can. The higher pressure which is required in the gap devices is preferably realized by a pressure booster. Thus, the hydraulic supply by the implement 2 or the carrier device with standard pressures is possible. After the splitting operation has been completed, the device can be moved, repositioned via the setup functions and a new drilling or splitting operation started.
