Definitions
- the invention relates to a hand-held soil compaction machine, in particular a vibratory rammer or a vibrating plate.
- Generic vibration tampers are known for example from EP 2 434 053 B1 and generic vibrating plates from DE 10 2012 01 7 777 A1. They are typically used in asphalt and earthworks to increase the strength of substrates. For this purpose, they have a superstructure and arranged on the superstructure drive means with at least one drive shaft.
- the drive device is usually an internal combustion engine, for example a gasoline, diesel or LPG internal combustion engine.
- the generic hand-held soil compacting machines have a substructure with a compression plate driven by the drive device.
- the compacting plate may be part of a tamper foot and, in the case of a vibrating plate, a vibrating plate.
- the drive device normally drives a vibration or vibration exciter, which, for example, displaces the padfoot of a vibration rammer in up and down movements or pitching movements or causes the vibration plate of a vibration plate to vibrate.
- a vibration or vibration exciter which, for example, displaces the padfoot of a vibration rammer in up and down movements or pitching movements or causes the vibration plate of a vibration plate to vibrate.
- the soil under the hand-held soil compaction machine is increasingly tamped or compacted.
- the walk-behind soil compacting machine can be moved across the ground in one working direction so that a desired area of a soil can be compacted in this way.
- the sensor device typically includes an acceleration sensor for this purpose.
- the soil stiffness increases with increasing Compression too, so that an operator can close from the achievement of a certain soil stiffness that the soil has been sufficiently compacted. How the soil stiffness can be calculated during the operation of a soil compaction machine is disclosed, for example, in EP 2 627 826 B1.
- the sensor device and display device is operated in the prior art from the electrical system or a battery of hand-held soil compaction machines.
- the ground stiffness can only be determined with reduced accuracy, but the display can be advantageously integrated, thus reducing the wiring effort. Nevertheless, in this case can not be completely dispensed with a wiring, since a power supply is needed.
- the object of the invention is therefore to provide a way, in particular with simple hand-held soil compaction machines with the lowest possible cost, a sensor device for determining the soil stiffness of a soil to be compacted can be operated.
- the solution of the problem with an hand-held ground compaction machine mentioned above succeeds in that the supply of electrical energy of the sensor device, in particular exclusively, by one of the at least one drive shaft, in particular directly driven generator. It is particularly preferred if the generator also supplies only the sensor device with electrical energy.
- the generator may for example comprise a dynamo or operate on the principle of a dynamo.
- the generator is typically configured to utilize rotational motion to generate electrical energy.
- the necessary rotational movement is provided, in particular directly, by the drive device, which drives a drive shaft, with which in turn the generator, in particular dere directly, is connected.
- the drive shaft is rotated by the drive means and this rotation in turn transmitted to the generator, which thereby generates electrical energy.
- the generator supplies only the sensor device with electrical energy and in particular forms a unit with the sensor unit.
- This generator and sensor unit can be mounted together as a complete assembly without the need for additional cable connections.
- Such a supply of electrical energy of the sensor device has been found to be particularly reliable and is also very compact, essentially maintenance-free, since it is not necessary, for example, to replace batteries from which the sensor device is driven, and also, as described in more detail below , suitable for retrofitting.
- the generator is driven by the operation of the drive means, the supply of the sensor device is at least and in particular exclusively in the working operation of the soil compaction machine continuously secured with electrical energy.
- the hand-held soil compacting machine therefore does not have to be equipped with a complete electrical system, in particular comprising a battery, or the sensor device can be operated autonomously by a vehicle electrical system.
- a complete electrical system in particular comprising a battery
- the sensor device can be operated autonomously by a vehicle electrical system.
- vehicle electrical system is understood to mean, in particular, a unit or a system having an electrical energy store, for example a rechargeable battery, in particular a lead-acid battery
- the vehicle electrical system also can supply an electric generator for charging the electrical energy store Components, but especially not just the sensor device according to the invention.
- One way to drive the generator is to use the drive shaft itself at the same time as a shaft for the generator by, for example, directly on the drive shaft magnets, in particular permanent magnets are mounted in a corresponding stator of the sensor device for training a Protrude dynamo unit.
- a connecting element may be present, for example a coupling.
- the connecting element is preferably a shaft drive, which connects the at least one drive shaft and the generator with each other, so that the rotational movement of the drive shaft is transmitted to the generator via the shaft drive.
- the shaft drive is a component which is axially fixed to the drive shaft or on an end face of the drive shaft and transmits the rotational movement of the drive shaft to the generator or makes it usable for the generator, for example a, in particular polygonal connecting pin.
- the shaft drive is thus at least partially a coaxial extension of the drive shaft.
- the sensor device or the generator connects directly in the axial direction of the drive shaft to the end face of the drive shaft or overlaps them.
- the generator, and in particular also the sensor device is arranged outside a housing of the superstructure and the shaft through-drive penetrates the housing.
- the drive shaft is within a housing of the superstructure.
- the generator, and in particular also the sensor device are arranged outside the housing, so that they can be easily mounted and maintained.
- the shaft through drive is preferably passed through the housing or through the housing wall and connects the drive shaft, in particular its end face, with the generator.
- the sensor device can also be viewed from the outside and can, for example, additionally comprise a display device on which the measured values and / or the soil stiffness and / or a display correlating with the soil stiffness are displayed.
- the at least one drive shaft may preferably be a directly driven by the drive means crankshaft.
- the generator for supplying the sensor device is driven by electrical energy directly or via the shaft drive from the crankshaft of the drive device.
- the drive device is designed such that the crankshaft exits from this on two opposite sides of the drive device.
- This embodiment is particularly preferred if on one side of the drive means the excitation unit is arranged for vibration or vibration excitation, which is driven by the crankshaft, and therefore there is no space for the generator or the generator and the sensor device is present , In this case, the generator is then driven from the other end of the crankshaft exiting on the opposite side of the drive means. The generator is thus driven by a portion of the crankshaft, which emerges from the drive means in relation to a further portion of the crankshaft from which the energizing unit of the soil compaction machine is driven. In this way, the generator and thus the sensor device according to the invention can be driven by the crankshaft, even in confined spaces, such as those present, for example, in vibration tampers.
- the at least one drive shaft may be an eccentric shaft or imbalance shaft driven by an eccentric gear or an unbalanced transmission of the drive device.
- the tamping tion of the padfoot typically achieved by rotation of an eccentric on which eccentric a connecting rod is attached, which converts the rotational movement in a linear up and down movement of the padfoot.
- the eccentric wheel is seated on an eccentric shaft, which is driven by an eccentric gear, for example a pinion, which meshes with the eccentric wheel, by the drive device, in particular via the crankshaft.
- an eccentric gear for example a pinion
- this eccentric shaft can now be used to drive the generator and thus to the electrical supply of the sensor device.
- the vibrating plates are usually caused by a rotating unbalance in vibration or vibrations.
- the imbalance is located on an imbalance shaft which is driven by a transmission (for example belt drive or hydraulic power transmission) by the drive device, for example by the crankshaft of the drive device.
- a further rotating shaft in this case the imbalance shaft, can be used to drive the generator and thus to supply the sensor device with electrical energy.
- the connection of the generator to the respective shaft corresponds to the embodiments described above. In principle, every housing-fixed shaft of the hand-held soil compaction machine is suitable for driving the generator.
- the rotational movement of the crankshaft is transmitted to the eccentric shaft or the imbalance shaft via the eccentric gear or the unbalanced transmission. It can therefore have the eccentric shaft or the imbalance shaft, in particular parallel, offset to a drive axis of the crankshaft of the drive means eccentric axis or unbalance axis.
- the offset between the respective axes of rotation is overcome by the eccentric gear or the unbalanced transmission.
- the eccentric axis or the unbalance axis may thus have a different position within the soil compaction machine. There is therefore a large number of different possibilities for connecting the generator to the respective shaft, so that the respective design can be adapted to the specific space conditions of the soil compaction machine, in particular of the superstructure.
- the sensor device comprises a transmitting device which is designed for the wireless transmission of the measurement results of the sensor device to a mobile receiving device.
- the mobile receiving device can be, for example, a tablet computer or a smartphone over which the operator of the hand-held ground compaction machine usually already has his own home. If a compatible data transmission, for example WLAN, is used, such a mobile terminal can be used as a receiving device if it is already carried by the operator of the soil compacting machine anyway.
- a smartphone or a tablet computer can be configured by the installation of a simple app to the data of the transmitting device of the sensor device receive and evaluate if necessary. In this way, no separate display device or evaluation on the hand-held soil compaction machine is necessary. In particular, a power supply for the display is unnecessary since the mobile receiving device generally has its own energy store.
- the invention is particularly suitable for retrofitting existing hand-held soil compaction machines, whether with an existing power source without.
- Both the sensor device and the generator and its drive connection are optimally suitable for installation in existing systems, since, for example, no integration into on-board electronics or otherwise has to take place.
- the components are very compact and can thus be well integrated with regard to the required free space.
- a further preferred embodiment of the invention therefore relates to a hand-held ground compaction machine with at least one further generator, which supplies other components of the hand-held ground compaction machine with electrical energy, for example spark plugs, wherein the supply of electrical energy of the sensor device takes place exclusively by the first generator and this preferably exclusively the sensor device is supplied with electrical energy.
- the generator and the supply of electrical energy of the sensor device are thus formed electrically completely separate from all other electrical components of the hand-held soil compaction machine.
- the sensor device derives its required power exclusively from the generator as described above and is completely independent of another power source, for example a further generator or a battery or an accumulator.
- the sensor device according to the invention together with the corresponding generator is also suitable as a retrofit kit for existing hand-held soil compaction machines, regardless of whether they already have electronics or not.
- the sensor device according to the invention can be used with the generator on all hand-held ground compaction machines.
- the sensor device and the generator supplying it with electrical energy are designed together as a module or as a coherent, in particular compact, structural unit, and in particular as a retrofit kit.
- the sensor device and the generator particularly preferably have a common housing and / or a common fastening device for attachment to the rest of the soil compaction machine. They are thus preferably mounted together as an independent module mounted on a hand-held soil compaction machine, so that they only, for example, via the shaft drive, connected to the drive shaft and, for example, must be attached to the housing on the superstructure.
- the sensor device comprises a memory unit.
- the measurement data of the sensor device are stored continuously and can be read from this.
- the storage unit enables the detection and monitoring of long-term trends and operating hours.
- the storage unit can also be provided separately from the sensor device and receive the measurement results from it, for example as part of the mobile receiving device.
- the sensor device is equipped with a bidirectional radio interface, which allows a wireless configuration of the sensor device.
- the sensor device is thus also designed to receive measurement results and to receive and implement configuration commands via which various functions of the sensor device can be controlled.
- the mobile receiving device is designed to send such configuration commands to an input of an operator.
- the position data of the receiving device and the duration of use of the compacting device allow documentation of the machine use. If, for example, the achievable quantity output is known in m 3 / h, it can be determined from the recording of the actual working time of the compacting machine whether the built-in quantity of material has also been compacted.
- the provision of the summarization display and other additional functions can also be limited in time and location via an Internet-based authorization.
- location monitoring is conceivable in such a way that the sensor device regularly reports the operating location of the machine via WLAN-based location as soon as a corresponding infrastructure is available. As a result, a theft protection can be realized in a simple manner.

- Fig. 1 is a side view of a vibration rammer
- Fig. 2 is a side view of a vibrating plate
- FIG. 4 shows a sectional view through a vibrating plate along the line IV from FIG. 2.
- Figures 1 and 2 show generic hand-held soil compaction machines 1, specifically a vibration tamper (Fig. 1) and a vibration plate (Fig. 2).
- the hand-held ground compaction machines 1 each have a guide bracket 2, with which an operator can direct the soil compaction machine 1 in working mode on the ground.
- the guide bracket 2 of the vibration plate shown in Fig. 2 can, as indicated by the dashed lines, be folded into a transport position.
- the hand-held ground compaction machines 1 have a superstructure 3, in which a drive device 4 is located, usually an internal combustion engine, for example a diesel or gasoline or LPG internal combustion engine.
- the soil compacting machines 1 have a substructure 5 with a compacting plate 7, 8.
- the compacting plate 7 is designed as a ramming plate, which represents the lower or ground-oriented end of the rammer foot 6.
- the compression plate 8 is a bottom contact plate in the form of a vibrating plate.
- the compression plates 7, 8 are set in the working operation of the hand-held soil compaction machines 1 by the drive means 4 in vibration or vibration.
- An operator leads the soil compaction machines 1, for example, in the direction of work a over the ground and thereby leads to a compaction of the substrate.
- the superstructure 3 of the hand-held soil compacting machines 1 in each case has a housing 9 which contains various components of the soil compaction machines 1.
- FIG. 3 shows a sectional view through the superstructure 3 of the vibration rammer from FIG.
- FIG. 3 shows the components of the vibration tamper within the housing 9.
- the drive unit 4 sets the crankshaft 10 in rotation about the drive axle 12.
- drives the drive means 4 via the crankshaft 10 a pinion 1 1, which is also about the drive axis 12th rotates and meshes with an eccentric wheel 13, which is thereby also offset by the pinion 11 in rotation.
- the eccentric 1 3 rotates about the eccentric axis 14.
- the eccentric 13 has an eccentric shaft 15 which is rotatably supported on the housing 9 via eccentric 16.
- the eccentric wheel 13 rotates, as a result of which the connecting rod 18 is set into a regular up and down movement.
- This up and down movement transmits the connecting rod 18 to the Stampferfuß 6 and thus leads to the drive of the compression plate 7.
- the pinion 1 1 and the eccentric 13 together form the eccentric 27, which drives the eccentric shaft 15.
- the eccentric 27 transmits in other words, the rotational movement of the crankshaft 10 of the drive means 4 on the eccentric shaft 15.
- the eccentric shaft 1 5 then rotates about the eccentric axis 14, which is parallel to the drive shaft 12 about which the crankshaft 10 rotates.
- a shaft drive 24 is disposed on the eccentric 13 opposite end face of the eccentric shaft 15, which penetrates the housing 9 and with a generator 26 of a sensor device 25, which is used to determine the ground stiffness of compacting soil is formed, connected.
- the shaft drive 24 continues the eccentric shaft 15 axially functionally on its end face and transmits the rotational movement of the eccentric shaft 15 to the generator 26, whereby the generator 26 produces electricity, which is used to supply the sensor device 25 and in particular their acceleration sensor and transmitter.
- the generator 26 and the sensor device 25 are arranged outside the housing 9. First, there is sufficient space on the vibratory rammer to accommodate the components, on the other hand, the sensor device 25 and the generator 26 is thereby accessible from the outside for an operator, for example, for maintenance purposes. The assembly of the sensor device 25 and the generator 26 can be carried out in this way easily from the outside.
- the generator 26 and the sensor device 25 are further formed as a continuous module with a common housing surrounding these two elements.
- Fig. 3 also shows an alternative embodiment of the invention in which the shaft passage 24, the generator 26 and the sensor device 25 are driven by the crankshaft 10 of the drive motor.
- the shaft drive 24 is arranged on the pinion 1 1 opposite end face of the crankshaft 10, wherein the crankshaft 10 at two opposite sides of the drive device 4 exits.
- the shaft drive 24 is driven by the side of the crankshaft 10, which is not connected to the pinion 1 1.
- the shaft drive 24 is connected directly to the crankshaft 10 in such a way that the crankshaft 10 sets the shaft drive 24 in rotation and thereby drives the generator 26.
- a drive means 4 which drives a crankshaft 10 about a drive axle 12.
- the crankshaft 10 in turn is connected via an unbalance transmission 19 with an imbalance shaft 20 and sets the imbalance shaft 20 in rotation about the imbalance axis 21st
- the unbalance transmission 19 is formed in the example shown as a belt transmission, but could for example be a gear transmission or the like.
- the imbalance shaft 20 is mounted on unbalance bearing 22 on an imbalance housing 28 and carries an imbalance 23, which is located within the imbalance housing 28.
- the imbalance 23 is likewise set in rotation about the imbalance axis 21, as a result of which the compression plate 8 is set into oscillations or vibrations.
- the sensor device 25 according to the invention and the generator 26 can be arranged in principle via the shaft drive 24 on each shaft fixed to the housing.
- the shaft drive 24 is arranged on an end face of the eccentric shaft 20.
- the shaft drive 24 penetrates the imbalance housing 28 or the housing wall of the imbalance housing 28 and transmits the rotation of the imbalance shaft 20 about the imbalance axis 21 to the generator 26, which is thereby driven and produces electrical energy for the sensor device 25.
- vibration plates Due to their design, vibration plates have markedly damped vibrations on the superstructure, which are only of limited use for the measurement of soil stiffness. This is for example due to a vibration decoupling of the imbalance housing 28 relative to the housing 9, for example via rubber elements.
- the attachment of the sensor device 25 directly to the imbalance shaft 20 is advantageous in various ways.
- the measurement of the soil stiffness is particularly accurate by measuring the vibrations on the imbalance housing 28 of the vibrating plate, at the same time the energy supply of the sensor device 25 is particularly easy to implement, since sensitive cable connections omitted.
- the direct attachment of the sensor device 25 to the imbalance shaft 20 also allows cost-effective integration further functions. For example, it makes sense to integrate a condition monitoring for the vibration bearings 22 in the sensor device 25.
- the condition monitoring could be done, for example, by the direct or indirect measurement of the storage temperature.
- rolling bearing typical frequencies can be extracted from the acceleration signal, and thus possible damage by evaluation of these signal components are automatically detected. Another additional function can be the determination of the actual working time with the machine.
- the sensor device 25 is equipped with a transmitting device which transmits the measurement results of the sensor device 25 and / or the calculated values of soil stiffness to a receiving device 29, in particular a mobile receiving device 29.
- the mobile receiving device 29 is, for example, a tablet computer or a smartphone of an operator of the hand-held ground compaction machines 1, on which a program, for example an app, is executed, which is designed to display or evaluate the measured signals and / or the calculated soil stiffness values.
- the sensor device 25 and the generator 26 are formed as a module.
- the sensor device 25 and the generator 26 form a unitary component or an independent module which can be mounted together on the corresponding mounting position on the hand-held ground compaction machine 1 or on the housing 9.
- the assembly takes place for all components together in just one step.
- the shaft through-drive 24 has to be connected to a drive shaft 10, 15, 20 and the unit of sensor device 25 and generator 26 to the soil compacting machine 1 or the housing 9 be attached.
- the invention is therefore particularly suitable as a retrofit kit for beautiful existing hand-held soil compaction 1 any type, whether they have a supply of electrical energy, a vehicle electrical system or any electronics of any kind.
