Definitions

  • the present invention relates to a hammer device according to the preamble of claim 1 and as from U.S. 4,548,278 A disclosed.
  • a ball mill is used in the cement industry, which are generally used for the coarse, fine and ultra-fine comminution or homogenization of ground material.
  • a ball mill consists of a grinding chamber that can be set in rotation, in which the material to be ground can be comminuted by grinding media, for example in spherical form.
  • the grinding chamber can be separated into individual chambers by one or more partition walls, which are usually designed as grids.
  • the first chamber can then be filled with the largest balls and the other chambers with smaller and smaller balls. In cement mills, this separation is carried out continuously by means of Gattier armoring, ie by separating the balls by means of impulses on bevelled grids.
  • the mill can be powered by a central opening in one of the end walls can be filled with the material to be shredded.
  • the discharge depends on the design. In the case of dry mills, the ground material is discharged through slots in the pipe wall at the end of the mill. The grinding media are retained in this way.
  • the added slots can reduce the throughput and thus the profitability of the ball mill, which is why the slot walls have to be cleaned regularly to remove the stuck clamping bodies.
  • this has usually been done by manual methods using manual striking tools or manual lever tools, by means of which the clamping bodies are driven further through the slot by a person (in the axial direction) or driven out of the slot again against the entry direction of the clamping body (in the opposite direction to the axis) or manually be levered out to the slot entry side.
  • This can be very labor-intensive and time-consuming as well as strenuous and also does not always lead to the desired cleaning of the slots.
  • the DE 10 2011 007 050 B4 describes a tool for loosening a component, in particular for pulling out an injection nozzle.
  • the tool has a frame which has two longitudinal members spaced apart from one another, a rear cross member extending between the two longitudinal members and a front cross member extending between the two longitudinal members.
  • the tool also has a coupling element which is provided in the area of the rear cross member, extends in the direction of the front cross member and is used to couple a head of a pneumatic hammer.
  • the tool also has a traction device, which in the area of the front cross member is provided, extends in a direction facing away from the rear cross member and is used to couple the assembly to be detached.
  • the DE 10 2011 007 050 B4 a commercially available, hand-held pneumatic hammer can be coupled in such a way that the compressive force of the pneumatic hammer in its axial direction can be converted into a tensile force on the component to be loosened in the opposite axial direction by means of the tool.
  • a pressure-generating vibration blow from the pneumatic hammer can be converted via the tool into a vibration train acting on the component to be loosened.
  • the tool can use the DE 10 2011 007 050 B4 a compressive force can be converted into a tensile force on the component to be detached.
  • the compressive force of the pneumatic hammer and the tensile force of the tool act along a common longitudinal axis of the pneumatic hammer.
  • the disadvantage here is that the tool DE 10 2011 007 050 B4 only forces, in particular tensile forces, can be exerted in one direction, namely in the counter-axial direction of the pneumatic hammer.
  • Another disadvantage is that the tool of the DE 10 2011 007 050 B4 only forces can be exerted on a component to be detached, which by means of a coupling with the tool of the DE 10 2011 007 050 B4 can be connected.

  • the tool can be received by the hammer device by means of a holding means.
  • the axial direction denotes one of the two directions of the longitudinal axis of the hammer device.
  • this hammer device is characterized by at least one impact force storage means which is designed to at least partially store an impact force of the impact mechanism in the axial direction and at least partially release it again as an impact force in the counter-axial direction.
  • the opposite axis direction denotes the direction of the longitudinal axis of the hammer device, which is oriented opposite to the axial direction.
  • An impact force storage means is understood to mean any means which is able to receive kinetic energy in the axial direction and at least partially, preferably as completely as possible, to release it again in the counter-axial direction.
  • the impact force storage means can be an elastic means but also a rigid means such as an impact body, in particular made of metal, which can direct the kinetic energy of the impact mechanism from the axial direction into the counter-axial direction by means of an impact effect.
  • the hammer device according to the invention is provided with an impact function which can act along the longitudinal axis of the hammer device in both directions, ie both in the axial direction and in the counter-axial direction.

  • the striking mechanism can be continuously in contact with the striking force storage means, ie for the entire duration or strength of the striking movement in the axial direction, or at least partially spaced from this along the longitudinal axis, so that only part of the duration or strength of the striking movement in axial direction can act on the impact force storage means. If there is continuous contact between the striking mechanism and the impact force storage means, the greatest possible impact force can be transmitted from the striking mechanism to the impact force storage means and thus the greatest possible impact force storage or rebound effect and output in the opposite direction.
  • the hammer mechanism can preferably be operated by means of compressed air, by means of pressurized fluid, by means of a fuel-operated drive and / or electro-mechanically.
  • drive means can be used.
  • an impact function on the tool can be brought about in the axial direction by means of a movable piston or impact mechanism and in the counter-axial direction by at least one impact force storage means charged during the previous impact or the rebound effect of a rigid impact body.
  • a gasoline engine for example, can be used as a fuel-powered drive.
  • the impacts in the axial direction can preferably have a higher energy than those in the counter-axial direction. This can be achieved through a lossy impact energy storage or directional change of the impact energy through the Striking force storage means are effected. These impact functions of different strengths can be advantageous due to a tool effect, but also due to the durability of the tool.
  • the impact force storage means is designed to be elastically restoring, preferably incompressibly elastically restoring.
  • an elastically restoring impact force storage means can release its energy back to the tool quickly and with little loss, counter to the previous impact direction.
  • the efficiency can be increased by using an incompressible impact force storage means.

  • the impact force storage means can easily be exchanged, e.g. to replace it if it is damaged or worn.
  • the impact force storage means can also be easily exchanged, so that a change in the rebound behavior of the impact force storage means can be achieved.
