    Hammer mechanism for a hammer device and method for opening a tap hole
    The invention relates to a striking mechanism for an axially replaceable in both directions 5 hammer device, in particular striking mechanism for a
    Rotary hammer for opening and optionally closing a taphole of a metallurgical vessel, comprising a displaceable by means of a pressure medium tube piston in a hammer mechanism housing and a centric or proximal, stiffenable, io connected at least with a tool, both sides anvil parts having transmission part of the impact energy and a means for reversing the pressurization of the tube piston, wherein the tube piston on both sides acted upon by the pressure medium, has substantially radial pressure surfaces and between the tube piston and 15 percussion housing grooves for reversing a
    Having Druckmediumbeaufschlagung the pressure surfaces and discharge or return of the medium.
    Furthermore, the invention relates to a method for opening or closing 20 a tapping opening in a provided with a refractory lining wall of a metallurgical vessel.
    Pneumatically or hydraulically operable hammers with a percussion mechanism, which in each case axially on both sides acted upon by pressure medium tube piston 25 are known in the art and, for example, in EP 0 930 476 B1. Such percussion devices are preferably used for devices which accomplish a propulsion or withdrawal of a tool in both directions, such as means for opening and closing tapping openings of metallurgical vessels and the like.
    A regulation within limits of the impact energy as well as the impact frequency of the cattail can be done in a complex manner by means of conversions of the 30 * * * * *· »··········································································. * ί * ·· «· ···· · * 4
    Hammer device or by adjusting the amount per unit time and / or the pressure of the supplied pressure medium done.
    In metallurgical vessels, such as blast furnaces and the like, it may be convenient to provide a high impact frequency and a low impact force of the tool for opening the tap hole in the wall.
    When pulling the drill tool from the tap hole after the breakdown, it is in each case to prevent jamming thereof, 10 procedurally advantageous to apply the highest possible kickback force even at lower impact frequency.
    The invention has for its object to overcome the disadvantages of percussion devices of the type mentioned for rotary hammers and to provide a simple way of controlling the beat frequency and the impact force of the cattail. Furthermore, a conversion of the impact frequency and impact force of the tubular piston in axial direction change of the tool load in practical use should be possible, if necessary, to meet specific requirements for Hammereinrichtungen, especially in 20 metallurgical plants.
    Furthermore, it is an object of the invention to provide a method for opening or closing tapping openings according to the type mentioned, which has an improved technology with increased reliability.
    This object is achieved with a generic percussion by the fact that in the tube piston a control recess and axially offset in percussion housing at least two control grooves for switching the 3o Druckmittelbeaufschlagung the tubular piston pressure surfaces are arranged and by a control means by means of connecting channels Umsteuerungsnuten are activated alternatively. 2 * ··· * ··· · t * · · ···· »· · φ * ·» · # ·· * · · ··· ♦ · ♦ ···· ···
    The advantages achieved by the invention are essentially to be seen in the fact that the tubular piston performs a different displacement or acceleration path, depending on the activation of one of the Umsteuerungsnute offset in the axial direction and such changes of the beat frequency and 5 of the impact force or impact energy are achieved. Thus, the longer the path for the return stroke of the pipe piston is provided to the reversal of the pressure medium, the lower the beat frequency and the higher the impact energy of the hammer and vice versa. 10
    Depending on the desired impact criteria of the hammer device can be adjusted with a simple control means the effectiveness of the Umsteuerungsnuten and thus set the working parameters. 15 A particularly simple and effective control of the
    Pipe piston movement is achieved when connected to the striking mechanism housing control means of the impact mechanism has a cylindrical recess with connecting channels to Umsteuerungsnuten Schlagwerkgehäuse and by means of axial positioning of a control piston in the recess 20 each one Umsteuerungsnuten activated.
    This embodiment of the control means has the advantage that by a simple displacement of the control piston in the recess each directly effective, short flow channel connections are created 25, which ensure a precise reversal of Rohrkoibenbewegung.
    According to an embodiment variant according to the invention, the control piston can be positioned manually or against a spring force by means of a pressure medium in the recess of the control means.
    In this way, an automatic adjustment of the tube piston movement can alternatively be achieved. 3 * »* ···« · I · * · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ··· be effected when the hammering device is moved hydraulically or pneumatically.
    If in a further embodiment of the invention, a hiring as well as a 5 removal of the hammer device on site by means of a pressure medium and thus the position of the control piston in the control means in dependence on the direction of impact of the hammer device is adjustable, for example, in ironworks open position or closing the Tapping of metallurgical vessels after a io favorable procedure be made automatically.
    The further object of the invention to provide an advantageous method using a hammer mechanism disclosed hereinbefore in a hammering device for opening or possibly closing a taphole in a refractory feed wall of a metallurgical vessel is achieved when propulsion and withdrawal of a tool done with different impact energy and / or with different beat frequency. 20 Refractory linings and the like repairs and sealants are extremely brittle and sensitive to cracking. Thus, if the tool is advanced with high impact energy when the tapping opening of a metallurgical vessel is opened, larger, funnel-shaped outbreaks may arise in the masonry, which necessitate a complex repair. A changeover of the impact energy and / or the impact frequency of the tool makes it possible to choose the most favorable impact technology in each case.
    If a conversion of the impact energy and / or the impact frequency of the tool is controlled by a change of propulsion to retraction of the hammer device in an advantageous manner, an improved
    Process technology of the tapping of metallurgical vessels with high efficiency can be achieved. 4 * ·· «········································································ ···
    It has proven to be particularly favorable when the propulsion of the tool with low impact energy and high impact frequency and the retraction of the same with high impact energy and low impact frequency are made. 5
    In such a way, the drilling process is optimized at a tapping position and, in the direction of advance, a funnel-shaped breakout from the masonry is largely avoided, and removal of the tool takes place without jamming at high speed, io
    An embodiment of the invention, which represents only a technical way of the same, is shown in the drawing and will be described below. 15 It shows
    Fig. 1 shows a striking mechanism with control means of a tubular piston
    A reference list is intended to facilitate the assignment of the functional means and parts in the representation. 20

    A cattail 1 is arranged axially displaceable in a percussion mechanism housing 2 and has distal pressure surfaces 11 and 11 ', which move the piston 1 when a surface is acted upon by a pressure medium.
    A reversal of the pressurization of the respective pressure surfaces 11 and 11 'of the tubular piston 1 is carried out with a conventional means, being exchanged for an i5 spring force by pressure or relaxation of a control device, the supply and discharge of the pressure medium. For operation in the impact mechanism according to the invention, a supply line 13 of pressure medium takes place by means of a recess in the impact mechanism housing 2. 20
    When a pressure surface 11 'on the tubular piston 1 is acted upon, it is axially displaced in the housing 2 until a connection of the supply line of pressure medium 13 and a control recess in the tubular piston 12 is achieved. 25 This results in a reversal of the pressurization on the pressure surface 11, which drives the tube piston in the opposite direction.
    A recess 12 on the tubular piston projects beyond two control grooves 3, 3 'with connection channels 31, 31' to a control means 4, in which the 30 connection channels 42, 42 'are continued in a recess 41 with a control piston 43. 6
    The control piston 43 has on the outer surface a recess, the is connected to an inner hollow and thus forms a discharge channel for a pressure medium, which channel cooperates with a discharge means 5 for a relaxed pressure medium. The control piston 43 is displaceable against a spring, so that its recess on the outer surface activates either the channels 31 in the striking mechanism housing 2 and 42 in the control means 4 or the axially spaced channels 31 'in the striking mechanism housing 2 and 42' in the control means 4. This results in alternatively a shorter or longer path of the tubular piston 1 to the reversal of the application of the pressure surfaces 11 and 11 '. A positioning of the control piston 43 in the control means 4 can be carried out in an advantageous manner respectively by the pressure medium for hiring or for a withdrawal of the hammer drill so that an automatically controlled with the axial direction of impact energy and / or impact frequency is reached. 7
