Definitions
- Hollow drill device with a display and method and system for determining and displaying a quality level for a drill hole cleaning
- the present invention relates to a hollow drilling device for generating a borehole, the hollow drilling device comprising a display with which a quality of a cleaning of the borehole can be displayed.
- the invention also relates to a system which comprises a hollow drill device and an external device and with which a drill hole cleaning quality level can be displayed.
- the invention relates to a method for determining and displaying a quality level for a well cleaning.
- drilling devices are known which are suitable for creating boreholes in sometimes very hard ground, such as concrete. These drilling devices work with drilling tools that work their way into the material to be drilled and thereby create the mostly round borehole.
- the drilling devices can be equipped with conventional, massive drilling tools.
- hollow drilling tools which are referred to, for example, as “hollow drilling bits”.
- the so-called “hollow drilling bits” the comminuted material produced during the creation of the borehole can be removed from the borehole through openings in the hollow drilling tool by being sucked out of the borehole with a vacuum.
- the drilling tool or the drilling device connected to it can be connected to a dust suction device which generates a negative pressure in a known manner. The negative pressure is set so that a sufficiently large suction volume flow is generated to suck the dust and the crushed material out of the borehole.
- the operator of the drilling device has to take complex measures to remove dust and comminuted material from the borehole after the borehole has been created.
- these measures consist, for example, in flushing the borehole produced several times with an air stream and / or wiping it out several times with a brush.
- An optimally cleaned borehole is desirable in order to ensure a good fastening effect or a stable connection between the substrate and the fastening material, such as dowels and / or anchors, in the borehole produced.
- the strength or the size of the suction volume flow with which dust and comminuted material is sucked out of the borehole can depend on various factors, so that in some cases it is difficult for the operator to recognize whether at any point in time during the operation of the drilling device, an optimal drill hole cleaning is achieved by the system of drilling device, drilling tool and dust extraction device.
- the various factors that can influence the quality of the borehole cleaning are in particular variable environmental conditions in the vicinity of the borehole to be generated, for example the type of dust extraction device used, the type of hose used, the condition of the filter in the dust extraction device or by the diameter of the hollow drilling tool or by the size and number of openings of the hollow drilling tool.
- the depth of the borehole, the performance class of the suction device used or the suction cross section can also play a role.
- situations can arise in which the operator or the user of the drilling system consisting of the drilling device, drilling tool and dust extraction device lacks information in order to be able to assess whether a sufficiently good drill hole cleaning is currently taking place.
- the large number of factors acting on the operator make it difficult for the operator to assess the borehole condition in terms of its degree of cleaning; this in particular because it is often not clear how the individual factors are related to one another or how they influence one another or interact with one another.
- the object of the present invention is therefore to overcome the disadvantages of conventional hollow drill devices described above and to provide a hollow drill device in which the operator can quickly and easily see whether the degree of cleaning of the borehole is in an acceptable range and whether no further measures to clean the borehole have to be taken. It would be particularly desirable if the user could receive quick, objective and reliable feedback on the cleaning status of the borehole, directly during the creation of the borehole, i.e. directly when drilling the hole.
- the object is achieved by a hollow drill device for generating a borehole, where the hollow drill device comprises a suction head for connecting the hollow drill device to a dust extraction device.
- the hollow drill device is characterized by that it comprises a display, the display being set up to display a quality level of a borehole cleaning, the hollow drilling device comprising a sensor for determining pressure conditions in the suction head and the display showing the quality of the borehole cleaning as a function of determined pressure values in the suction head.
- the proposed display is a “vacuum-controlled display”, since the display of the different degrees of quality of the drill hole cleaning takes place as a function of the pressure conditions within the suction head of the hollow drill device.
- pressure ratios in the context of the invention preferably denotes the pressure that prevails in the suction head when the hollow drill device is in operation. This is particularly a negative pressure, since the dust extractor preferably sucks in dust and impurities using negative pressure in order to suck the dust into the interior of the dust extractor through the suction pipe.
- negative pressure refers in particular to a pressure which is lower than the usual atmospheric pressure or the pressure of the environment in which the hollow drill device is operated. In this respect, it is particularly preferred within the meaning of the invention that the display indicates the quality of the borehole cleaning as a function of the negative pressure values determined in the suction head.
- the hollow drill device in particular in the area of the suction head, includes the sensor for determining the pressure conditions in the hollow drill device or that the sensor is arranged in spatial proximity to the suction head of the hollow drill device.
- the display for the well cleaning quality is arranged on the suction head.
- the arrangement of the display on top of the suction head is particularly advantageous because the display is thus directly in the field of vision of the operator of the hollow drill device and can be seen by the operator without turning his head away from the borehole.
- the proposed arrangement of the display device achieves optimum visibility during the drilling process.
- the sensor can preferably be an electronic pressure sensor.
- the pressure sensor is preferably set up to send the determined pressure conditions or the borehole cleaning quality data derived therefrom to the display of the hollow drilling device to transfer. If the hollow drilling device interacts with an external device, such as a mobile communication device, it can also be preferred that the determined pressure conditions or the borehole cleaning quality data derived therefrom are transmitted to the external device using the preferably electronic pressure sensor. The data collected can then be displayed with a display device of the external receiver device. The data transmission between the hollow drilling device and the external device preferably forms a communication link which is preferably part of the system comprising the hollow drilling device and the external device. This communication connection preferably works using the preferably electronic pressure sensor.
- the preferably visual display device is designed in the area or as a component of the suction body.
- the present invention is based on the knowledge that the quality of a borehole cleaning, which in the sense of the invention is preferably also referred to as borehole cleaning efficiency, is related to the pressure conditions in the suction head of the hollow drill device.
- the detection of this correlation advantageously makes it possible to determine the pressure inside the suction head with a sensor and to use the pressure values thus determined to determine the quality of the cleaning of the borehole.
- suction volume flow in the context of the invention preferably denotes that air flow with which dust can be sucked out of a borehole using negative pressure when a hollow drilling tool is used during drilling.
- a hollow drilling tool can preferably be equipped with openings in its front area, where the contact with the material to be drilled through, and these openings can be subjected to a negative pressure by a Staubabsaugevor direction.
- a particularly inexpensive element for example a tube with a spring
- the tube can, for example, be designed as a preferably elastic membrane, with the preferably elastic membrane being able to be deflected by the pressure difference in the suction head depending on the size of the pressure difference.
- a deflection height of the membrane is preferably determined by the determined pressure values in the suction head, the deflection height of the membrane advantageously being able to be used to indicate the preferably colored pressure levels or the drill hole cleaning quality levels.
- the deflection of the preferably elastic membrane is preferably determined by the pressure conditions, in particular the pressure differences or the suction volume flow in the suction head.
- the suction volume flow preferably determines the suction quality in the area of the borehole wall.
- a higher suction volume flow leads to improved cleaning of the borehole wall.
- a major advantage of the invention is that the operator of the hollow drilling device with the proposed display receives feedback from the proposed device as to whether the cleaning of the borehole during drilling is sufficient to be able to refrain from further measures to clean the borehole after its completion .
- An optimally cleaned borehole leads to higher dowel pull-out forces, so that an improved fastening quality can be achieved if sufficiently clean boreholes are used to receive fastening mortar or the base material for a chemical dowel.
- the invention thus advantageously increases the safety of the fastening produced with the borehole or of the building built with it.
- the stability of the attachment can be effectively increased by applying the invention.
- the hollow drill device comprises means so that the pressure values determined in the suction head are transmitted to the display.
- the transmission of this data can be wireless or wired.
- the data can be transmitted from the pressure sensor to the display device with a data cable within the device.
- wireless communication means are used for the data transmission.
- predefined reference values for example, different quality grades such as “good”, “sufficient” and “there is a need for action” can be assigned to individual value ranges.
- These different levels of quality can be indicated by the display, for example using a traffic light color system. In other words, it is very particularly preferred that different degrees of quality of the drill hole cleaning are displayed with different colors.
- the display is an optical display.
- the quality grade “good” for the drill hole cleaning can be marked with the color “green”, while for example the quality grade “sufficient” is marked with the color “yellow” and the quality grade “there is a need for action” with the color red.
- the display can, for example, also be designed in such a way that two different quality grades for drilling hole cleaning are distinguished and displayed.
- a first grade can consist in the fact that the borehole cleaning efficiency meets the requirements for satisfactory borehole cleaning, it being possible for this state to be marked, for example, by emitting a green color signal.
- a second grade of quality can consist, for example, in the fact that the requirements for adequate borehole cleaning are not met.
- This second quality grade can be identified, for example, with a color signal kept in the signal color red.
- This second quality grade “red” can, for example, also indicate or mean that the hollow hole drill is blocked.
- the use of the color “red” in the context of the present invention is preferably to be understood to mean that the user is shown that the drill hole cleaning is not optimal and that action is required.
- the display device can in particular be referred to as a “binary display”. In the context of the invention, it is particularly preferred that the display device changes its color when, for example, a previously established or predefined negative pressure level is undershot.
- the displayed color preferably correlates with the determined pressure values and / or the suction flow volume values derived therefrom, which is in the context of the present invention is referred to as a display of the borehole cleaning quality “as a function of determined pressure values”.
- the display is arranged directly in the field of vision of the operator of the hollow drill device, so that the operator can keep an eye on the display while working. In particular, the operator does not have to look away from the borehole if he wants to see the display and at the same time operate the hollow drill device.
- the display device has a small size so that it advantageously does not distract the operator from the work or block his view.
- the pressure-controlled display device is arranged or placed in or on a suction head of the hollow drill suction.
- user support can advantageously be provided with which the safety and stability of a connection between a chemical anchor and a borehole can be improved by the operator of the hollow drilling device can easily see at any point in time during operation of the device whether the borehole cleaning during drilling is sufficiently good or not.
- the invention enables monitoring or monitoring of the cleaning of the borehole, for example when the pressure values determined with the sensor or the data evaluated with the evaluation unit are stored for the suction volume flow. The data can then be read out at a later point in time and / or used for documentation purposes.
- the proposed invention also relates in particular to the display device, it being possible for the display device to be placed, for example, on a suction head of a hollow drill device.
- This display device can preferably also be referred to as a control display.
- the display can indicate, for example with one color, that the drill hole cleaning is insufficient.
- the operator after drilling the hole, the operator would have to carry out the measures that are required when using a conventional drilling device without a hollow drilling tool in order to clean the borehole and prepare it for further fastening work. These measures consist in particular of flushing the borehole produced with a stream of air several times and wiping it out with a brush.
- the display can include lighting means, for example, the lighting means being set up to emit light in different colors, ie with different wavelengths or frequencies.
- the display device can either include a light source that emits “white” light that is colored with different filters.
- the display comprises different illuminants which emit light in different colors.
- the display can also be set up to flash at intervals, with different flashing frequencies being able to mark different degrees of quality of the drill hole cleaning, for example.
- the invention in a second aspect, relates to a system which comprises a hollow drilling device and a mobile communication device as an external device.
- the mobile communication device can be a smart or mobile phone, a notebook, a laptop, a handheld device, a tablet or the like, without being limited thereto.
- the mobile communication device comprises a display device, such as a screen, a touch screen, a monitor or a display, the mobile communication device being set up to take over the display function of the display of the proposed hollow drill device.
