Definitions

  • the invention relates to a receptacle for a tubular drilling tool on a drilling gear with radially arranged locking pin which engages in a corresponding opening of the drilling tool.
  • the locking pin is conical or frustoconical at its inwardly facing end, so that even with not exactly exact alignment with the opening in the drilling tool locking is possible.
  • This condition can be z. B. form in that the drilling tool is slightly deformed, or are clamped between the tool holder and drilling tool small stones or other hard impurities. The condition can also change during operation form. In these cases, a very large force must be exerted on the drilling tool on the conical portion of the locking bolt, the z. B. ensures that any foreign bodies are pushed out, or the slight deformation of the tube are pushed back. It follows that the normally almost force-free insertion of the locking bolt in these limit operating situations may require an extremely high operating force.
  • a medium speed should also be run and a medium current flow, which is in the order of magnitude of the commissioning range.
  • slip ring tracks which are only used for transmitting data or control commands, this is not the case in principle.
  • the invention has made the creation of a tool holder to the task, in which an accidental and unintentional opening of the locking bolt is largely excluded.
  • the solution to this problem is a receptacle for a tubular drilling tool on a drilling gear with a radially arranged locking bolt which engages in a corresponding opening of the drilling tool and characterized in that the locking bolt, in a sleeve is rotatably and slidably disposed and on the locking bolt a radial outwardly facing pin is located, which engages in a helically extending in the sleeve, slot-like backdrop, seen from the surface of the sleeve, the scenery in the front area, the retraction of the pin, obliquely to the axis of rotation of the locking bolt and sleeve and in the rear area , the locking position of the pin, is arranged transversely to the axis of rotation and wherein the locking bolt is rotatable by a crank-shaped and arranged transversely to the axis of rotation lever with pressure cylinder acting thereon.
  • the locking bolts of the tool holder should be introduced not only by moving into the openings of the drilling tools, but by an additional rotational movement in a corresponding guide initially quickly and with little force into the tool are guided and towards the end of insertion on their cone a possibly required, Carry out subsequent fine adjustment of the drilling tool in the recording and can not be pushed out of this locking position in its position from the drill pipe backwards.
  • the drive for this rotational movement is to allow a high speed and a low actuation force by a corresponding translation to a pressure cylinder out in the beginning of the locking movement and limit the entry speed in the locking position, but exert the highest possible application of force in the pressing direction.
  • the locking bolt should be guided so that it is guided beyond its locking position out into a stable position, in which it can not be moved out easily by acting on him, non-directed vibrations or vibrations.
  • a key idea of the invention is the movement of the locking bolt via a pin, which is guided by a helically extending in the sleeve, slot-like backdrop.
  • This slot-like backdrop extends as seen from the surface of the sleeve obliquely to the axis of rotation of the locking bolt. If the slot-like backdrop - contrary to the core idea of the invention - over the entire area away only a single would incline (slope) would correspond, they correspond in their effect a well-known spindle or screw.
  • the peculiarity of the invention is that the pin can easily follow different inclinations (gradients) of the backdrop through the circular design.
  • a further increase in safety is achieved in that the pin in its locking position or in its safety return position is held by a blockage.
  • the blockage is pressed with spring force on the pin on the bolt. This blockage prevents release of the locking bolt when subjected to intermittent, non-directional forces (shaking and shaking).
  • a tool holder according to the invention proposes various advantageous embodiments of the energy store. It is known to arrange a simple pressure accumulator on the housing of the machine. This accumulator is fully exposed to the operational vibrations of the tool holder. In order to save installation space and costs, the invention prefers shell-shaped pressure accumulators which, like the segment of a cylinder, conform to the outer wall of the tubular tool receptacle. The shape of this memory is also describable as the segment of a ring as a floor plan, on which the walls are erected vertically.
  • the accumulators enhance the structure of the tool holder by forming ribs on the outside.
  • these ribs lie so flat on the body that a Bohrwerkssuit invention has a comparatively small outer diameter.
  • the locking bolt is guided by a rotational movement in the drilling tool, because it is guided by its axially outwardly directed pin, which engages in the slot-like backdrop, with different inclinations (gradients).
  • the scenery thus provides a non-linear translation due to the different inclinations the rotary and the linear movement of the locking bolt ago. Therefore, different drive systems are conceivable for the rotational movement of the bolt.
  • the movement is possible through a rotating pneumatic drive, a rotating hydraulic drive or a rotating electric motor.
  • the invention prefers to put on the locking bolt a crank-shaped lever which is moved by a cylinder. This arrangement is not only comparatively simple and inexpensive, but adds by the combination of crank and cylinder another, non-linear, special sinusoidal characteristics in the E-nergieübertragungskette.
  • crank it is advantageous to arrange the crank so that it is perpendicular to the piston rod of the printing cylinder in that point of the movement sequence in which the conical part of the locking bolt has fully emerged from the inner surface of the tool holder. At this point she enters the drilling tool. In the case of any inaccuracies must act from then on the cone of the locking bolt on the drilling tool and sometimes exert considerable forces depending on the inaccuracy occurred. In this final phase of the introduction of the locking bolt very high forces are required, but not very high travel speeds - unlike during the beginning of the introduction phase of the bolt.
  • the invention proposes to make this range of angular position of the crank outwardly visible to the operator by setting a screen in front of the crank is, which makes the crank recognizable only in this range of angular position for the operator.
  • the crank itself serves as a display device for secure locking.
  • a Positionistgeber is arranged, by means of which an electrical signal, for example, can be tapped that the crank is in the locking region of the bolt.
  • the invention proposes as actual value magnets, Hall generators, encoders or other electronic systems. They should in any case be connected to an additional locking indicator on the tool holder. It is conceivable, for example, a lamp or setting up an additional indicator lever. Useful is the additional connection of this information with a remote control system.
  • the linear actuator preferred by the invention, a pneumatic cylinder.
  • the invention also proposes for the pneumatic cylinder the cultivation of Positionistwerter linearen.
  • Another security element should be the verification of a sufficient amount of energy in the energy storage, so monitoring z.
  • a manometer has already been described.
  • Another possibility is an electronic pressure sensor, which can be evaluated via the interface of the remote control.
  • One of the essential principles of this invention is an energy storage and supply for the operation of the locking pin in the tool holder, which manages without complex rotary feedthroughs.
  • the disadvantages of a hydraulic rotary feedthrough described in the introduction also apply, in principle, to a pneumatic rotary feedthrough, with the difference that escaping air generally does not cause any secondary damage.
  • An electrical energy transfer by means of brushes and slip rings and their disadvantages have also been described in detail.
  • an inductive coupling is conceivable for electrical energy transmission without mechanically contacting parts: an exciter coil on the stationary part is arranged concentrically within a further coil on the rotating part.
  • An alternating electric current in the stationary part generates a pulsating magnetic field, which penetrates the secondary coil on the rotating part and thereby generates a current.
  • This current can be used directly as an energy source for an electric drive of the locking bolt.
  • a useful extension of such an electrical system is a backup battery, which ensures the reliability of the entire system even with short-term failure of the electrical energy supply. In a mechanically sufficiently protected against vibration execution, for Example by casting the coil, this type of energy supply is wear-free.
  • a utilization variant of the electrical energy supply is the electric drive of a pneumatic pump for supplying a compressed air reservoir.
  • the remote control technology makes sense to also use the electrical energy to operate a remote control via radio or infrared or ultrasound.
  • the electrical energy is also predestined for the supply of electronic elements for actual position detection at the various points of the drive mechanism for the locking bolt.
  • a particularly economical solution is the pneumatic operation of the tool holder.
  • the invention proposes a pressure accumulator for this purpose. Very low investment costs arise when a mass-produced storage tank is mounted in the interior of the tool holder.
  • Another variant of the invention is the cultivation of cylinder-segment-shaped storage on the outer wall of the tool holder. This invention allows the function as a compressed air storage function as a space-saving stiffening ribs.
  • the invention proposes an additional pressure cylinder, on the piston rod a flywheel is arranged, wherein the piston rod is aligned in the direction of the impact movement of the drilling tool and the outputs of the printing cylinder via one-way valves (check valves) and pressure lines to the compressed air reservoir are connected.
  • This arrangement represents a non-contact transmission of energy into the tool holder into it.
  • a particular advantage is that no additional facilities need to be created outside of the tool holder. Rather, the impact movement is tapped for the drilling tool. Since the energy consumption of the tool holder itself is almost negligible compared to the energy for the impact movement, an amplification of the impact movement in practice is not required.
  • the tool holder After each impact movement, the tool holder experiences a very high acceleration. This acceleration also experiences the flywheel on the additional pressure cylinder. Due to its inertia, a force vector, which runs opposite to the direction of the impact movement, forms on the flywheel. Since the flywheel is movable in this direction via the piston rod, the piston moves within the pressure cylinder and builds up a pressure. The resulting increased air pressure is transferred via the compressed air line and the check valve in the compressed air reservoir. With a time delay compared to the rest of the tool holder, the flywheel will move the piston in the impression cylinder to the opposite stop and back with each impact movement.
  • Another variant of this compressed air supply according to the invention is the utilization of the placement process of the tool holder on the tool.
  • the additional pressure cylinder is to be arranged for this variant such that its piston rod extends in the direction of the wall of the drilling tool.
  • the piston In the resting state of Bohrwerksit, ie without an inserted tool, the piston is pressed by spring force down. By putting on the edge of the drilling tool, the piston is pressed into the pressure cylinder.
  • the compressed air thus formed is transferred via pressure line and check valve in the compressed air reservoir.
  • the spring presses the piston rod down again.
  • This hub also generates compressed air, which is supplied to the compressed air reservoir.
  • the additional cylinder is to be dimensioned so that its energy quantity covers the energy requirement of the locking bolt and additionally builds up a certain safety margin.
  • the tool holder it is a very cost-effective variant, about once a working day to charge the compressed air reservoir via a hose and an external, standard on the carrier already existing compressor. For this it is of course necessary that the energy storage is sufficiently large to store the amount of energy for the entire locking and unlocking movements.
  • the invention proposes two variants for the electric drive of the locking bolt.
  • a rotating electric motor accesses the locking bolt either by direct coupling or by coupling via a gear and will thereby set it in rotation.
  • Another variant of an electric drive is the replacement of the pneumatic or hydraulic cylinder against an electric linear drive.
  • the electric linear drive acts on the locking bolt via the crank and turns it.
  • electromagnet which surrounds the locking bolt and pushes it into the tool for locking purposes.
  • a further variant of the invention is the replacement of the axially in the drilling tool driving in locking bolt against a locking claw.
  • the locking claw pivots about an axis which is parallel to the drilling tool and located on the outer wall of the Bohrwerksfact.
  • the advantages of this arrangement are its low construction volume (more compact dimensions) and the low reaction by forces exerted by the drilling tool on the conical part of the locking claw.
  • a cylinder is proposed according to the invention, which is arranged tangentially to the outer surface of the tool holder and performs the pivoting movement via an additional pivot point on the locking claw.
  • the articulation point of the impression cylinder can be chosen so that the effective lever arm is then greatest, when the locking claw enters with its conical part in the drilling tool.
  • Another drive variant according to the invention for the locking claw is the introduction of a helical backdrop on the drive claw.
  • This backdrop corresponds to the course and structure of the previously described in detail, slot-shaped gate for the pin on the locking bolt.
  • the advantages thus achieved also apply to this drive variant of the pivotable locking claw.
  • To move in this case also serves a cylindrical pin which engages in the slot and is guided linearly in the direction of the pivot axis of the locking claw.
  • the invention proposes a very ample dimensioning of this guide. In the event of improperly aligned tools, or in the case of slightly deformed tools, and the consequent repercussion of significant forces backwards into the pivot mechanism via the locking claw, a sufficiently sized guide will be able to block this movement.
  • a remote control For a particularly secure tool holder and for a particularly detailed feedback on the operating state of all elements in the locking movement, it is advantageous to a remote control to provide for the transmission of the operating command from the operator to the tool holder.
  • This remote control avoids the problem of rotary feedthrough.
  • Another advantage is that the transmission path is not affected by moisture and dirt. It is according to the prior art possible and useful to encapsulate the receiving unit in the tool holder and suspended vibration damped.
  • this transmission path is also used to transfer information from the tool holder back to the operator.
  • meaningful information is the pressure in the compressed air reservoir, the position of the cylinder and the angular position of the lever on the locking bolt.
  • the invention proposes for the example of the pneumatic variant with pressure cylinder, that in the supply line of the pressure cylinder for the actuation of the locking bolt an externally accessible changeover valve is integrated, to which an additional pressure cylinder is connected , whose piston rod is movable via an externally accessible handle.
  • This arrangement is advantageous as an emergency operating function if the compressed air reservoir no longer has sufficient reserves or if the remote actuation of the valves for activating the individual cylinders has failed.
  • a manual emergency operation of the lock according to the following sequence is possible: switching the pressure cylinder to manual mode and pumps on the handle for the purpose of actuating the locking lever. have been saved becomes the time-consuming disassembly of the connection from the crank-shaped lever to the pressure cylinder.
