Definitions

  • the invention relates to a method for determining the operating time and the operating state of a hydraulic impact unit, in particular a hydraulic hammer according to the preamble of claim 1.
  • the invention further relates to a hydraulic impact unit, in particular a hydraulic hammer with a percussion piston according to the preamble of claim 18th
  • Such a method or such an aggregate is, for example EP 0 461 565 A known.
  • Hydraulic impact mills in particular hydraulic hammers, are used for material comminution (for example crushing rock or concrete).
  • This comminution is achieved by the kinetic energy of a percussion piston is introduced by impact on a tool on this and the tool tip in the material to be processed and converted there into destructive work.
  • the kinetic energy of a percussion piston is introduced by impact on a tool on this and the tool tip in the material to be processed and converted there into destructive work.
  • the kinetic energy is transformed into destructive work; the unconverted energy component is reflected by the tool into the percussion piston.
  • the impact energy is completely transformed into destructive work.
  • Hydraulic impact units of the type mentioned - known from the document DE 34 43 542 C2 - represent, also with regard to the otherwise harsh operating conditions, highly stressed devices that require from the point of view of economic efficiency and reliability of close observation and appropriate care or maintenance.
  • service life of the hydraulic percussion unit ie an indication of the total time span during which the hydraulic percussion unit has been actively used.
  • the invention is therefore based on the object to provide measures and means by which the operating time and the use state of a hydraulic percussion unit - especially recognizable to an operator - determine. In this way, the competent body has the opportunity to decide whether there is already a need for maintenance or whether the relevant impact unit can continue to be used.
  • the object is achieved by a method having the features of claim 1.
  • the invention is based on the recognition that the current total number of strokes executed by the stroke represents a relevant variable for the determination of the active operating time, from which - by comparison with appropriate specifications - a statement about the operational state of the respective impact unit can be derived ,
  • the statement about the use state in the simplest case is that it is made clear whether the end of a maintenance-free operating period is reached and thus there is a need for maintenance.
  • the inventive method for determining the operating time and the use state of a hydraulic percussion unit is characterized in that signals are generated during the individual, successive operating sections of the percussion unit, the number of which is proportional to the executed by the percussion piston in a direction strokes; that the number of signals is continuously accumulated and stored as a total; and that the respective current total number of signals is made recognizable, at least temporarily, in the form of an indication indicating the condition of use.
  • the last mentioned display can be optical and / or acoustic in the context of the invention.
  • the mode of production and the type of signals can be arbitrary in the context of the invention, as far as it is ensured that their number allows a statement about the number of strokes executed by the percussion piston in one direction of movement. In question comes in particular the generation of signals by means of a sensor that detects due to the percussion piston movements occurring physical processes (or related state changes).
  • the signals are generated as a function of at least one of the physical processes - pressure, displacement, sound level, temperature, flow and vibration - (claim 2).
  • the invention can also be further designed so that the determined in the manner mentioned current total number of signals in response to at least one other predictor - for example, the measured ambient temperature - is provided with a correction factor, so that the end of a maintenance interval recognizable making display - When falling below a predetermined outside temperature - triggered at an earlier time.
  • the method can also be carried out in such a way that the percussion strokes proportional signals due to a sound measurement (claim 6) or by detecting vibration processes (claim 7) are generated.
  • this can be done with the aid of a Schallmeßwertgebers in the form of a microphone, which is optionally followed by a suitable filter.
  • the vibrations caused by the movements of the percussion piston can be detected by means of a vibration transmitter; this has a vibrationally held in the manner of a seismic mass and cooperating with a plunger vibration sensor. The latter is excited by relative vibrations with respect to the plunger coil from the percussion outgoing, whereby signals corresponding to the vibrations are generated by inductive means.
  • the method can also be designed such that the displacement of a moving due to the percussion piston strokes in a direction of movement component of the percussion unit is detected by means of a Wegmeßwertgebers (claim 8).
  • the movements of the percussion piston itself can be converted into corresponding signals that it is enclosed without contact by an induction coil unit.
  • the latter is preferably assigned to the percussion piston on the side facing away from the percussion piston top side of the percussion unit.
  • the method can also be designed such that the stress of a component of the percussion unit - which changes periodically with the strokes executed by the percussion piston - by means of a force orchrochronsmeßwerts detected (claim 9).
  • transducers can be used which are designed as strain gauges or as piezoelectric elements and convert the stress states occurring in them to signals.
  • the respective transmitter are mounted on the housing of the percussion unit so that they are deformed with its caused by the Schlagkoben strokes stress.
  • suitable signals can also be generated by detecting the temperature or the pressure of the gas cushion by means of a temperature transmitter or a pressure monitor (see claims 10 and 11, respectively). Since the gas cushion is normally arranged on the side facing away from the percussion piston tip side of the percussion unit, the sensors mentioned here (temperature transmitter, pressure switch) are relatively far away from the immediate working area of the percussion unit.
  • the method is further developed from the point of view of reliability and economy such that upon reaching a predetermined total signal number at least one maintenance indicator is generated, which makes at least recognizable that the percussion unit requires maintenance (claim 12). This can be done, in particular, by the fact that, if necessary, a - for example red - warning lamp lights up, which indicates the end of a maintenance-free operating period.
  • These pre-warnings may consist of first lighting a green warning lamp and, at a later point in time, a yellow warning lamp, before reaching an upper limit of the predetermined signal total, which, so to speak, gradually indicates the current operational state of the striking unit.
  • the electrical energy required for the provision - that is, in particular for the extraction, summation and storage - of the signals can be generated by batteries or rechargeable batteries.
  • the energy units concerned should be equipped with a charge indicator in order to rule out any incidents.
  • the method can also be designed in such a way that the electrical energy for the provision of the signals is generated by means of the fluid, which also drives the percussion piston (claim 16).
  • an electric power unit may be provided which has an auxiliary hydraulic motor with a generator driven therefrom and an electric accumulator connected downstream of the latter.
  • the electrical energy for the provision of the signals can also be generated by means of a generator which becomes effective on the basis of the movement processes triggered by the percussion piston strokes and to which an electric accumulator is connected downstream (claim 17).
  • this automatically operating generator can correspond in particular to the previously mentioned vibration transmitter.
  • the hydraulic excavator 1 shown in Fig. 1 has a supply unit 2 with a diesel engine, not shown, and a hydraulic pump driven therefrom (cf., Fig. 3a); this is connected in a conventional manner to a hydraulic hammer 3, which in turn is held adjustably on the boom 4 of the hydraulic excavator with two boom arms 4a, 4b.
  • the cantilever arm 4b in turn carries a pivotable terminal bracket 5, to which a support member 6 formed as a support housing or as a support frame - is attached. At this the hydraulic hammer 3 is supported via its housing 3a.
  • the hydraulic hammer 3 acts on a tool designed as a chisel 7, wherein the kinetic energy emanating from the hydraulic hammer is converted into impact energy.
  • a display element A is arranged, which makes, among other information about the operating life and the use state of the hydraulic hammer 3 recognizable.
  • the hydraulic hammer has a sensor S for generating signals which are continuously accumulated in the display element A, stored as a total number and made recognizable.
  • Fig. 2 shows schematically in more detail the sequence and the interaction of the processes that eventually lead to a statement about the operating time and the use state of the hydraulic hammer 3.
  • the events occurring on the occasion of the operation of the hydraulic hammer 3 are converted into signals by the sensor S, continuously accumulated in a counting and storage element ZS in terms of their total number and stored as a total, the current total number of signals on the on the use state of Hydraulic hammer indicative display A is made recognizable.
  • the required for the provision of the signals and the information derived therefrom electrical energy is provided by an electric storage E available. If necessary, the information obtained by means of the counting and storage element ZS can be transmitted wirelessly to an evaluation AW.
  • the senor S is arranged and designed such that during the individual, successive operating sections of the hydraulic hammer 3 signals are generated, the number of which is proportional to the executed by the percussion piston of the hydraulic hammer in a direction strokes.
  • the sensor thus detects events or states or state changes which are triggered by the percussion piston movements and maps these processes, states or state changes into signal form.
  • a statement about the active operating time can be obtained, from which - with regard to predetermined maintenance intervals - information about the operating state of the hydraulic hammer 3 can be derived. This information can be made visible on the display A and optionally wirelessly the evaluation AW out.
  • the display A can be constructed such that after reaching a predetermined signal total number at least one maintenance indicator is generated, which makes recognizing the achievement of the end of a maintenance-free period of operation period.
  • the display may also be such that it generates, depending on the respective current signal total number of times consecutively several prewarning indications that indicate in stages the approach to the end of a maintenance interval.

  • the smaller piston surface K1 is constantly acted upon by a pressure line 12, which is in communication with the return line 10, with the working pressure.
