Definitions

  • the invention relates to a hand-held implement, in particular an implement for soil compaction.
  • the implement can in particular be designed as a vibrating machine, in particular as a soil compacting device.
  • Soil compaction devices in particular vibrating plates or vibrating rollers, are known. They essentially consist of a lower mass with a tool, for example a soil contact element, which is moved over the soil to be compacted and subjected to vibrations generated by a vibration exciter.
  • the vibration exciter is usually an imbalance exciter in which, for example, two counter-rotating imbalance shafts generate a resulting force that causes the desired vibration.
  • an upper mass which is movable relative to the lower mass and has a drive, for example an internal combustion engine, a machine frame and optionally a drawbar for guiding the vibration plate.
  • the upper mass usually also includes a fuel tank, a starter battery, control elements and - if present - parts of a hydraulic system.
  • the internal combustion engines provided for driving the vibration exciters on the upper mass can usually be started via electric starters with starter batteries.
  • the starter batteries can consist, for example, of grid plate accumulators that are designed for motor vehicles to participate in road traffic.
  • the vibration amplitudes occurring in the vibration machines are orders of magnitude higher than those occurring in normal road traffic.
  • the problem often arises that the grid structure of the vibration-sensitive starter batteries can be damaged due to the vibrations, so that the starter batteries fail.
  • the invention is therefore based on the object of specifying a hand-held working device in which the vibrations acting on the starter battery and the operator are as low as possible.
  • a vibration plate for soil compaction is particularly suitable as a working device.
  • a hand-held tool is specified, with a lower mass, which is a tool and a working device for effecting a working movement of the tool has; with an upper mass which is movable relative to the lower mass and has a drive component for the working device; with a first vibration decoupling device arranged between the lower mass and the upper mass for vibrationally decoupling the upper mass from the lower mass; with a guide tongue for guiding the implement by an operator; and with an electrical energy store for Providing electrical energy for the drive component; a drawbar carrier being provided, which is carried by the upper mass and which is connected to the upper mass via a second vibration decoupling device; wherein the guide tongue is attached to the tongue carrier; and wherein the energy store is carried by the drawbar carrier.
  • the lower mass is essentially formed by the working device and the tool.
  • the working device can be, for example, an imbalance exciter that drives a ground contact plate that is used as a tool or causes it to vibrate (working movement).
  • the upper mass has at least one drive component, which can be designed, for example, as a drive motor for the working device, in particular as an internal combustion engine.
  • the drive component can also be designed as a control component.
  • the drive component can therefore also be designed as an additional battery (also referred to below as a traction battery), electric motor, voltage and/or frequency converter, electronic controller and/or circuit breaker.
  • a fuel tank, an engine cooling device, a cooling fan, a protective frame or a centrifugal clutch, for example, can also be arranged on the upper mass.
  • the energy store carried by the drawbar carrier can be defined as the first energy store, wherein the drive component can have a second energy store, which can be arranged on the upper mass.
  • the drive motor can also be part of the drive component and can therefore be arranged on the upper mass.
  • the drive motor can also not be part of the drive component and can be arranged, for example, on the lower mass, for example directly on the working device (e.g. the vibration exciter).
  • the second energy store can serve to supply the drive motor arranged on the upper mass or on the lower mass.
  • a transmission device can be provided for transmitting the drive power of the drive motor arranged on the upper mass to the working device be.
  • This can be, for example, a belt drive or a hydraulic coupling, for example to drive the unbalance exciter on the lower mass.
  • the drive motor can be arranged on the upper mass, with its drive power being able to be transmitted to the lower mass with the named transmission device.
  • the drive motor can be arranged on the lower mass. In this case, the use of an electric motor is preferred, which can be coupled to a vibration exciter.
  • the energy store (possibly also referred to below as the first energy store) can be, for example, a starter battery, for example for an electric starter provided on the internal combustion engine.
  • the energy store (or the first energy store) can also be a secondary battery for providing electrical energy, e.g. for control devices of the motor, or also part of the traction battery that supplies the electric motor with drive energy .
  • the electric motor can be supplied with drive energy, for example, by both energy stores, namely the first energy store and the second energy store. The electrical energy required for the electric motor is then stored in a distributed manner in the two energy storage devices.
  • the drawbar carrier is connected to the upper mass via the second vibration decoupling device.
  • the drawbar carrier can be movable relative to the upper mass within certain limits that are specified by the second vibration decoupling device.
  • Both vibration decoupling devices can be formed with the help of an elastic bearing and in this way allow relative mobility of the components coupled to one another (lower mass - upper mass; upper mass - drawbar carrier) in order to prevent or at least reduce the transmission of vibrations from one component to the other.
  • the first vibration decoupling device and the second vibration decoupling device are functionally connected in series between the lower mass (and thus the location where the vibrations occur) and the components to be protected (battery; guide pole). This adds up Vibration decoupling effect of the two vibration decoupling devices.
  • the energy store carried by the drawbar carrier or the first energy store (e.g. the battery, starter battery, traction battery, part of the traction battery) and the guide drawbar are vibrationally decoupled from the actual place of vibration generation, namely the working device in the lower mass.
  • the vibrations on the lower mass are effectively damped or reduced by the vibration decoupling devices connected in series with respect to the battery and the guide tongue in order to protect the battery and the guide tongue from high vibration effects. Accordingly, the operator is also protected from excessive vibration when grasping the drawbar at its end to guide the work implement with his hands.
  • the drawbar carrier can be arranged in an area of the upper mass that faces the operator. This means that the drawbar carrier can be arranged in particular in the rear, rear part of the upper mass, seen in the forward direction of travel. Accordingly, a suitable recess for the drawbar support and the second vibration decoupling device is to be provided in the rear part of the upper mass.
  • the guide pole can be pivoted relative to the pole carrier.
  • the guide pole can be pivoted either upwards for a transport position or downwards for an operating position.
  • the guide pole can be fastened to the pole carrier via a rotary bearing, for example an axle.
  • a resilient stop is provided in order to support the guide pole in this lower position.
  • the stop can be realized, for example, by a rubber or plastic buffer.
  • the second vibration decoupling device can have several connection points between the drawbar carrier and the upper mass.
  • the connection points allow on the one hand the reliable mechanical coupling between Drawbar carrier and upper mass. On the other hand, they also ensure vibration decoupling between the two components.
  • connection points can be provided between the drawbar carrier and the upper mass, with three of the four connection points spanning an imaginary (virtual) plane and the fourth connection point having a perpendicular distance from the plane that corresponds to at least half of the smallest distance that having the fourth connection point to the nearest one of the other three connection points.
  • the four connection points can thus be arranged in a kind of tetrahedron in order to achieve a particularly stable and effective arrangement in space and to reliably hold the drawbar carrier with the guide drawbar on the upper mass.
  • the second vibration decoupling device must be suitable for reliably transmitting the steering and control forces, which the operator brings in with his hands at the end of the guide pole, to the upper mass and thus to the lower mass. In particular, this results in tilting and torques which are introduced by the operator via the guide pole into the pole carrier and which are to be transmitted by the second vibration decoupling device.
  • the arrangement of the four connection points ensures a broad base of moments in order to introduce the executives and moments directly into the upper mass and thus into the implement.
  • the fourth connection point is outside the plane that is spanned by the three other connection points.
  • the distance between the fourth connection point and the plane should be as large as possible in order to make the imaginary (virtual) tetrahedron as large as possible.
  • connection points are provided between the drawbar carrier and the upper mass, with at least two of the six connection points being arranged at a different height level than the remaining connection points, based on an intended position of use of the implement in a horizontal plane.
  • connection points it is also possible to arrange connection points outside of imaginary planes, so that the advantageous tetrahedron arrangement described above can be achieved by four of the six connection points in each case.
  • the difference in height level can be, for example, at least 50% of the smallest distance between the remaining connection points.
  • connection points can each be formed by buffer elements and can be realized, for example, as rubber buffers or plastic buffers.
  • the buffer elements should have at least a low level of elasticity in order to be able to develop the vibration-decoupling effect.
  • the buffer elements can each have a central axis in their longitudinal direction, with the central axes of the buffer elements of all connection points being able to extend in at least three different spatial directions.
  • the buffer elements are constructed in a manner known per se and can, for example, have two metal plates (plates, discs) spaced apart from one another, between which an elastic rubber or plastic element is provided. The respective forces are introduced via the plates provided at the end and are elastically absorbed by the rubber or plastic element.
  • the rubber or plastic element thus also serves as a spring and damper element.
  • the central axes of the buffer elements should therefore deviate from one another and extend in three different spatial directions. As a result, the central axes are at an angle to one another or are skewed. Of course, it can make sense to arrange the buffer elements in pairs in such a way that the best possible accommodation of the active executives can also be achieved here.
  • the buffer elements can be arranged in such a way that they are subjected to pressure and/or shear during operation of the implement, but not to tension. Accordingly, the fastenings of the buffer elements on the drawbar carrier and the upper mass are to be designed so that no tensile effects can be brought about in the buffer elements with normal force effects due to the prevailing vibrations and the executive forces introduced by the operator.
  • a protective frame can be provided which is rigidly connected to the upper mass.
  • the protective frame then represents part of the upper mass.
  • the protective frame can be rigidly connected to the drawbar carrier instead of to the upper mass.
  • the protective frame is separate from the upper mass and is not part of the upper mass.
  • the guide pole can have an elongate extension, with a handle bar being provided on an end facing away from the upper mass or the pole carrier for gripping by the operator.
  • the operator can grip the handle not only to guide the implement.
  • the handlebar as a control element for setting the running direction of the implement, for example a vibrating plate.
  • the handlebar can be pivoted relative to the end of the drawbar, with the pivoting movement of the handlebar being detected in a suitable manner and transmitted to an imbalance exciter in the lower mass.
  • the function and effect of such a vibrating plate control is known per se and will therefore not be discussed in greater detail at this point.
  • the implement can in particular be a vibrating plate for soil compaction.
  • 1 shows a vibration plate driven by an internal combustion engine for soil compaction as an example of a working device according to the invention in a perspective view from above.
  • 2 shows the vibration plate from 1 in side view. While in the presentation of 2 the vibration plate with a is equipped with the protective frame explained later, this is in the view of 1 removed for better display.
  • the vibration plate has a lower mass 1 and an upper mass 2 arranged above the lower mass 1.
  • a part of the lower mass 1 is a soil contact plate 3 which is used as a tool and is moved with its underside over the soil to be compacted.
  • a vibration exciter 4 is arranged, which can be designed, for example, as a known imbalance exciter.
  • the imbalance exciter has, for example, two imbalance shafts rotating in opposite directions, on each of which an imbalance mass is arranged. The counter-rotation generates a resulting force vector that forms the desired vibration. Due to the rigid coupling between the vibration exciter 4 and the soil contact plate 3, the vibration is introduced directly into the soil contact plate 3 and can therefore be used effectively for soil compaction.
  • Fastening devices 5 are also provided on the lower mass 1, on each of which buffer elements 6 made of a rubber or plastic material are arranged.
  • the buffer elements 6 are part of a first vibration decoupling device, which decouples the vibrations of the upper mass 2 from the lower mass 1, which vibrates strongly during operation.
  • a protective frame 7 is arranged on the upper mass 2 as part of the upper mass 2 ( 2 ), which however - as mentioned above - in 1 is not shown.
  • a drive motor (not shown) for driving the vibration exciter 4 is also part of the upper mass 2. This can in particular be an internal combustion engine. However, it is also possible to implement the drive motor as an electric motor.

  • the battery 13 can also serve as part of a traction battery that supplies the electric motor with the necessary electric drive energy. Another part of the traction battery can be provided directly on the upper mass than not - like the battery 13 - on the drawbar support 8, which is vibrationally decoupled from the upper mass.
