Definitions

  • the present invention relates to a method for controlling a water supply system for use with a machine tool, in particular a core drill, comprising a water storage for storing water, a conduit for transporting water from the water storage to the machine tool, the conduit having a first portion and a second section, a pump means for conveying water from the water reservoir to the machine tool, a signaling device, at least one sensor for measuring at least one parameter of the pump device and a control device.
  • a water supply system is an essential and indispensable necessity in almost every core drilling job as well as in numerous other work with large machine tools (such as saws or cut-off machines).
  • a core drill for drilling holes in mineral rock by means of a rotating drill bit cooling and rinsing of the individual components of the core drill and drill bit is necessary.
  • the core drill there is a general possibility of the core drill to a fresh water line, such. a conventional water pipe, to connect and thus to produce the necessary cooling and flushing.
  • a water supply facility instead of connecting a core drill to a fresh water line which cools the drill bit while processing the material and, in particular, spills off the rock dissolved by the drill bit and dust, a water supply facility provides the ability to transport a particular supply of water to the worksite.
  • the water supply system has this for a fresh water storage in which a certain amount of water for cooling and rinsing is stored.
  • a water supply system has a conduit in the form of a flexible hose to pump the water to the machine tool or to the drill bit can.
  • Core drilling is complex and requires constant monitoring of the core drill bit as well as the drill bit during preparation and throughout the actual drilling process.
  • the gear of the core drill, the drilling speed, the torque, the drilling progress and the amount of water needed for cooling and rinsing must be changed or adjusted.
  • a continuous and sufficient flow of water to the core drill and drill bit must be ensured throughout the core drilling operation.
  • the water serves both to cool the core drilling rig and to muddle out drilling mud (mixture of dissolved rock, dust and water) from the drill bit. If sufficient flow of water to the core rig and drill bit can no longer be achieved, there is a risk of overheating of the core drill as well as hard drilling of the drill bit in the drilled hole.
  • the core drill and the drill bit can be permanently damaged, which can lead to a delay in the completion of the core hole and high costs for the time-consuming disassembly of the stuck drill bit and their repair.
  • a method for controlling a water supply system for use with a machine tool, in particular a core drill comprising a water storage for storing water, a conduit for transporting water from the water storage to the machine tool, the conduit having a first portion and a second portion includes, a pump means for conveying water from the water reservoir to the machine tool, a signaling device, at least one sensor for measuring at least one parameter of the pump device and a control device.
  • the user of the core drill By sending a signal, the user of the core drill is informed in good time during the execution of a core drilling that only a small amount of water is still available for cooling and for flushing, and appropriate measures, such as, for example, an interruption of the core drilling process, must be initiated to prevent a hard drilling of the drill bit or other damage.
  • the at least one parameter of the pump device may be the water pressure in the pump device.
  • the at least one parameter of the pump device is the receiving power of the pump device.
  • the predetermined amount of water is realized by the internal volume of the second section of the line.
  • Fig. 1 shows a water supply system 1, which is connected to a machine tool 2.
  • the water supply system 1 is configured to carry out the method according to the invention.
  • the water treatment plant 1 essentially comprises a housing 3, a water reservoir 4 for storing water, a line 5 for transporting water from the water reservoir 4 to the machine tool 2 designed as a core drilling machine, a signal device 6, a pump device 7 for conveying water from it Water storage 4 to the core drill 2, a sensor 8 for measuring at least one parameter of the pump device 7 and a control device. 9
  • the housing 3 is designed substantially as a hollow body.
  • the water reservoir 4 is positioned in the housing 3 and serves as a reservoir for water. Alternatively, another suitable liquid may be used.
  • the conduit 5 is configured in the form of a flexible tube and includes a first end 5a and a second end 5b. As described in detail below, the conduit 5 includes a first portion 17 and a second portion 18. The first end 5a of the conduit 5 projects into the water reservoir 4 and the supply of water. The second end 5b of the pipe 5 is connected to a connector 13 on the core drill 2.
  • the line 5 is used to transport fresh water from the water reservoir 4 to a designed as a drill bit tool 14. As in Fig. 1 shown, the line 5 is connected via the connector 13 with the core drill 2 that the water enters the interior of the drill bit 14. The water cools and flushes the drill bit 14 during a drilling operation.
  • the water penetrates through a first end 14a of the drill bit 14 into the interior of the drill bit 14 and out of the drill bit 14 again through a second end 14b.
  • the drill bit 14 includes a catcher 15 having an outlet port 16 at the second end 14b. Through the outlet port 16, the water exits the drill bit 14 together with the drilling mud (not shown) for disposal.
  • the line 5 is first performed for cooling by the core drill 2 before it finally reaches the drill bit 14 for cooling and rinsing.
  • the diameter of the conduit 5 is six millimeters (6 mm). It is also possible that the diameter is less than 6 mm. With a maximum diameter of the line 5 of 6 mm, it is ensured that at least the water which is located downstream in the line behind the pump device 7, is still promoted to the drill bit 14 when a portion of the line 5 upstream of the pump means 7 contains no more water and the pump means 7 instead of water pumps only air.
  • the pump device 7 is connected to the line 5 and serves to promote or pump fresh water from the water reservoir 4 to the drill bit 14.
  • the pump device 7 is a diaphragm pump. However, it is also possible to use any other suitable type of pump. Due to the positioning of the pump device 7 in the line 5, the line 5 is divided into a first section 17 (partial section A to B) and a second section 18 (partial section C to D).
  • the first portion 17 includes a first end 17a and a second end 17b.
  • the first end 17a of the first section 17 projects into the water reservoir of the water reservoir 4.
  • the second end 17b of the first section 17 is connected to the pump device 7.
  • the second portion 18 of the conduit 5 includes a first end 18a and a second end 18b.
  • the first end 18 a of the second section 18 is connected to the pump device 7.
  • the second end 18b of the second portion 18 is connected to the connector 13.
  • the sensor 8 for measuring at least one parameter of the pump device 7 is in accordance with the in Fig. 1 shown embodiment designed as a water pressure sensor. According to an alternative, but not shown embodiment, the sensor 8 may also be configured as a sensor for measuring the recording power of the pump device 7.
  • the in Fig. 1 illustrated water pressure sensor 8 is connected to the pump device 7 and serves to measure the water pressure in the pump device 7. According to an alternative and not shown embodiment, it is also possible that the water pressure sensor 8 does not measure the water pressure in the pump device 7, but in the first and / or second section 17, 18 of the line 5.
  • the signaling device 6 is in accordance with the in Fig. 1 shown embodiment designed as an acoustic signal transmitter (horn). According to an alternative, but not shown embodiment, the signaling device 6 may also be designed as a visual signal transmitter (lamp) or as a combination of an acoustic and a visual signal generator.
  • the control device 9 is connected to the sensor 8 and the signal device 6.
  • the control device 9 serves to receive and evaluate data, in particular measurement data, from the sensor 8. Furthermore, the control device 9 monitors, controls and regulates the pump device 7 Control device 9, the signal device 6.
  • the control device 9 thresholds or limits for the individual parameters, in particular water pressure in the pump device 7 and recording power of the pump device 7 are stored.
  • the core drill 2 is connected to the line 5 for supplying water for cooling and rinsing (see. Fig. 1 ).
  • the pump device 7 conveys water from the water reservoir 4 via the line 5 to the drill bit 14.
  • the designed as a water pressure sensor sensor 8 continuously measures the pressure of the water in the pump device 7 and sends this data to the controller 9.
  • the controller 9 continuously compares the received Measurement data with the threshold values stored in the control device 9. If the water pressure in the pump device 7 drops below a certain threshold value for a certain period of time due to an empty water reservoir 4 and an empty first section 17 of the line 5, the control device 9 sends a corresponding signal to the signaling device (horn).
  • Horn signaling device 6 issues a warning signal to notify the (not shown) user of coring device 2 that the water supply is nearly exhausted.
  • the warning signal is only the inner volume of the second portion 18 of the conduit 5 for cooling and rinsing the drill bit 14 is available.
  • the configured as a diaphragm pump pump device 7 is able to continue to pump in the interior of the second portion 18 of the line 5 remaining water to the drill bit 14.
  • the user of the core drill 2 thus knows that only the content (internal volume) of the second section 18 of the line 5 is pumped to the drill bit 14 and no water is pumped in a short time.
  • the senor 8 is designed such that the power consumption of the pump device 7 is measured.
  • the data measured by the sensor 8 are sent to the control device 9 and compared with correspondingly stored threshold values. If, as a result of an empty water reservoir 4 and an empty first section 17 of the line 5, the transmitted measurement data falls below the threshold values for a certain period of time, a warning signal is output via the signal device 6.
  • the warning signal serves the user be aware that the water supply is almost used up and only the content (internal volume) of the second portion 18 of the line 5 for cooling and rinsing is available.
