Definitions

  • the invention relates to a device for filling boreholes by means of one- or multi-component adhesive, filling, sealing or filling compounds, with storage containers for the masses to be filled, a dispensing device and a pressing device which can be interacted with a hand lever for supplying the masses from the storage containers to the delivery facility.
  • a device is e.g. B. is known from US-A-3,058,632.
  • a measured amount of a hardening mass is packaged in a destructible envelope.
  • This packaging is inserted into the borehole and destroyed using the anchor rod in the borehole.
  • This method is relatively complex, in particular from the point of view of the necessary packaging, and therefore leads to high costs.
  • the packaging leads to problems because it can be damaged prematurely, for example during transport or handling, outside the borehole and can therefore become unusable.
  • the mass is introduced into the borehole using a device consisting of large storage containers which generally contain the mass for several boreholes.
  • a device which consists of a tube which can be filled with the mass and which can be inserted so deeply into the borehole that its mouth lies against the bottom of the borehole. While withdrawing the pipe from the borehole, its content is pressed out by means of a piston which can be displaced in the pipe.
  • This method is extremely cumbersome due to the tube that has to be refilled before each insertion process and is associated with contamination due to dripping mass.
  • the retraction of the tube is entirely left to the operator's hand, which allows the retraction to be carried out too quickly, possibly causing air pockets.
  • the invention has for its object to provide a device that enables a clean, air-free filling of the borehole.
  • the dispensing device has a feed nozzle and a mouthpiece, the feed nozzle being connected to the device and, viewed in the dispensing direction, the mouthpiece adjoining the feed nozzle and insertable into the boreholes while dispensing the masses by means of an actuating device is telescopically displaceable against the feed nozzle.
  • the displacement of the mouthpiece is coupled with the delivery of the masses. It can thus be achieved that the mouthpiece is only pulled out of the borehole to the extent that it is already filled with the mass.
  • the mouthpiece can be inserted into the feed nozzle or can comprise it. In the latter case, the feed port filled with mass serves as an ejection piston for the mouthpiece. If the mouthpiece is inserted into the feed nozzle, the mouthpiece serves as an ejection piston.
  • the mass is brought from the storage containers into the dispenser by means of the squeezing device.
  • the squeezing device it is advantageous that channels opening out of the storage containers into the feed pipe are provided.
  • the channels can be designed as tubular connecting pieces or as recesses in the housing.
  • the channels opening from the storage containers into the supply connection piece can be arranged as desired. From a fluidic point of view, however, it is expedient if the channels open essentially radially into the feed connector.
  • the components stored separately in the storage containers must be mixed with one another before being introduced into the borehole.
  • a radial flow of the channels into the feed connector creates a mixed flow in the feed connector.
  • the channels can be arranged opposite one another or adjacent to one another. In both cases, the flow results in a good mixture of the components.
  • additional baffles serving to deflect the flow can be arranged in the feed connection.
  • the masses are filled into the boreholes.
  • the mouthpiece is tubular.
  • the outer diameter of the mouthpiece can essentially correspond to the borehole diameter.
  • the mouthpieces can be exchanged for different borehole diameters.
  • the individual components when using multi-component materials, the individual components must be mixed with one another before being introduced into the borehole.
  • the mouthpiece In order to achieve thorough mixing, it is therefore expedient for the mouthpiece to contain a mixing insert. Due to the mixing insert, the components are broken down into partial streams when they flow through the mouthpiece and brought together again. If this is done several times in succession, the components are mixed homogeneously. If the components that have been mixed together harden in the area of the mixing insert after a long shutdown, the mixing insert together with the mouthpiece, just be replaced.
  • the mouthpiece After the mouthpiece has been inserted into the borehole, the mouthpiece is pulled out of the borehole while the masses are being dispensed by means of the actuating device.
  • the actuating device is designed as a feed unit that can be connected to the hand lifting.
  • the feed unit can consist, for example, of a toothed rack and a latching lug interacting with it.
  • a simple clamping device is also possible.
  • the connection of the actuating device to the hand lever enables a gear ratio that is adapted to the conditions. Since the effort to pull back the mouthpiece is relatively small, this translation can be chosen to be relatively large, so that only a few strokes of the hand lever are required to pull back the mouthpiece.
  • the feed connection and the mouthpiece are to be filled on the one hand by means of the squeezing direction and on the other hand the mouthpiece is to be withdrawn by means of the actuating device. Since these two functions are to be carried out at different times, it is expedient that a switchover device is provided for the mutual transmission of the movement of the hand lever to the actuating device and to the squeezing device. Depending on the position, the switching device enables one or the other function to be carried out. The hand lever does not have to be released.
  • the switching path required for switching is relatively short. However, various spring forces must be overcome.
  • the switching device is designed as an eccentric lever.
  • An eccentric lever requires simple turning as a switching movement. By conveniently setting the eccentricity or the switching angle, the switching device can be designed so that it is automatically locked in the end positions and no special holding elements are required.
  • the device according to the invention which can be seen from FIGS. 1 to 4, is used to fill a borehole 1 in a receiving material 2.
  • the device has a housing, designated overall by 3.
  • the housing 3 consists of a rear part 3a receiving the drive mechanism and a front part 3c releasably connected thereto via a snap lock 3b.
  • a handle 4 is formed on the rear part 3a.
  • the front part 3c has a stop 5 for supporting the device on the receiving material 2.
  • two storage containers, generally designated 6, are arranged side by side for receiving the masses to be filled.
  • a piston 6a is slidably guided in each of the storage containers 6.
  • the plunger 7 has a shaft 7a which is provided with tooth catches 7b.
  • the front end of the plunger 7 is designed in a manner known per se as a cutting edge 7c for cutting through the wall of the storage container 6.
  • a hand lever 8 arranged in the area of the handle 4 is rotatably mounted about an axis 9.
  • the hand lever 8 is brought into the illustrated starting position by a torsion spring 10.
  • a pawl 11 is pivotally connected to the hand lever 8 via an eccentrically arranged pin 12. In the position shown in FIG. 1, the pawl 11 is brought into engagement with the toothed catches 7b of the tappet 7 by means of a ball 13 supported on the housing 3 and a spring 14.
  • a locking cam 15 is also due to the force of a compression spring 16 in engagement with the tooth pegs 7b. The locking cam 15 prevents the plunger 7 from being pushed back when the pawl 11 grips.
  • a feed pipe designated overall by 17.
  • the feed connector 17 is connected to the storage containers 6 via channels 18.
  • the channels 18 open essentially radially into the feed connector 17.
  • Baffles 17a are arranged in the rear region of the feed connector 17.
  • the baffles 17a result in thorough mixing of the components flowing from the storage containers 6 into the feed connection 17.
  • a mouthpiece, designated overall by 19, is telescopically displaceable relative to the feed connector 17.
  • the retraction of the mouthpiece 19 is carried out by an actuator, which we substantial consists of a rack 21 connected to the mouthpiece 19 and a latching lever 22 which can be brought into engagement with the rack 21.
  • the locking lever 22 is also articulated on the hand lever 8.
  • the locking lever 22 is pressed by a leaf spring 23 against the rack 21.
  • a locking lever 24 is provided in order to avoid advancing the toothed rack 21 when the locking lever 22 is gripped.
  • the locking lever 24 is pivotally mounted about a pin 25 and is also pressed against the rack 21 by means of the compression spring 16.
  • a total of 26 eccentric lever serves as a switching device.
  • the eccentric lever 26 has an eccentrically arranged pin 26a. In the position shown in FIGS.
  • the pin 26a presses on the locking lever 22 and brings it out of engagement with the rack 21 against the force of the leaf spring 23.
  • the locking lever 24 is connected to the pin 26a via a linkage 27 and is also kept out of engagement with the rack 21.
  • the pawl 11, on the other hand, is in engagement with the tooth catches 7b of the tappet 7.
  • the mouthpiece 19 and the associated rack 21 are freely movable and are moved by the mass flowing into the feed connector 17 until the rack 21 stops on the feed connector 17 to the left, ie against the receiving material 2.
  • the housing front part 3c can be removed for replacing or filling the storage container 6.
  • the cross section shown in FIG. 2 through the housing rear part 3a shows the tappet 7 and the pawl 11 which is in engagement therewith and the locking cam 15.
  • the toothed rack 21, which is U-shaped in cross section can be seen.
  • the locking lever 22, which is also U-shaped in cross section is arranged.
  • This design enables a partial nesting of the pawl 11 and the locking lever 22 and thus results in a compact design.
  • the leaf spring 23 is connected to the locking lever 22.
  • the locking lever 22 is pressed down by the pin 26a of the eccentric lever 26 against the force of the leaf spring 23.
  • the pawl 11, however, is freely movable upwards.
  • the locking lever 24 is also pressed down against the force of the compression spring 16 and thus kept out of engagement with the rack 21.
  • FIG. 3 shows the device according to FIG. 1 while the mouthpiece 19 is being pulled back. This is made possible by turning the eccentric lever 26.
  • the pin 26a eccentrically arranged on the eccentric lever 26 moves upwards, i. H. away from handle 4.
  • the pin 26a presses on the pawl 11 and, against the force of the spring 14 supported on the ball 13, disengages it from the toothed catches 7b of the plunger 7.
  • the detent lever 22 and the locking lever 24, on the other hand, are released and come through the force of the leaf spring 23 or the compression spring 16 in engagement with the rack 21.
  • the hand lever 8 is actuated, the rack 21 and the mouthpiece 19 connected to it are now withdrawn. Compared to the position shown in FIG.
  • the mouthpiece 19 has already been pulled out of the borehole 1 by the path s. A corresponding part of the mass was ejected into the borehole 1 by means of the mouthpiece 19 acting as a piston through its bores 19a and the mixing insert 20.
  • the stop 5 serves to support the device on the receiving material 2.
  • the mass contained in the feed connector 17 is displaced as far as possible by the mouthpiece 19 and ejected into the borehole 1 .
  • the eccentric lever 26 is then brought back into the position shown in FIGS. 1 and 2.
  • the locking lever 22 and the locking lever 24 come out of engagement with the rack 21 and the pawl 11 engages again in the tooth catches 7b of the plunger 7.
  • the filling of the feed connector 17 can thus begin again.
  • the mouthpiece 19 together with the rack 21 is brought back into the position shown in FIG. 1.
