GROUND COMPACTING DEVICE WITH ELECTRICALLY OPERATED WHEEL

SET

Description

The invention relates to a ground compacting device, in particular a vibration plate or plate compactor.

Such a ground compacting device has a vibration exciter driven by a motor, which vibration exciter generates a substantially vertically directed vibration which acts on a compacting plate (ground contact plate). Depending on its design, the vibration exciter is suitable for moving the compacting plate also forwards or backwards over the ground to be compacted and for making the plate steerable.

Such a ground compacting device is known as a vibration plate, for example, from

DE 198 40 453 A1. It has an extendable running gear, so that a shorter distance on a construction site can be covered with the machine without a transport vehicle being required.

The running gear mechanism described in DE 198 40 453 A1 is structurally complex, heavy and expensive. In contrast, DE 102 26 920 A1 discloses a simpler transport device in which a wheel set is directly attached to the compacting plate (ground contact plate). By tilting the vibration plate about the wheel set, the ground contact plate can be lifted off the ground and the entire vibration plate can be transported or rolled away with the aid of the wheel set.

Even if the tilting and transporting in particular of smaller vibration plates is considerably simplified by the wheel set on the ground contact plate, a considerable effort is still required for pushing or pulling the machine. This applies especially also to larger, heavy vibration plates.

DE 18 00 257 U1 describes a device for compacting road covers, having a mobile frame on which a combustion engine and a generator connected thereto are disposed. A compacting plate provided with a vibration exciter is mounted on the frame movable on wheels.

2 EP3 901 372

The invention is therefore based on the object of providing an improved ground compacting device which can be transported conveniently and without special effort.

The object is achieved according to the invention by a ground compacting device having the features of claim 1. Advantageous developments of the invention are presented in the dependent claims.

The invention relates to a ground compacting device, having a lower mass comprising a compacting plate, an upper mass coupled to the lower mass via a vibration decoupling device, a vibration exciter acting upon the compacting plate, a running gear having one or a plurality of roller bodies for transportation of the device, and having an electric drive for driving at least one of the roller bodies, wherein an electric power store is provided to supply the electric drive with electric power.

Accordingly, the lower mass comprises the compacting plate used as the ground contact plate, on which the ground compacting device stands on the ground. The compacting plate is caused to vibrate by the vibration exciter and brings about compacting of the ground located underneath. The vibration exciter or parts of the vibration exciter can also be assigned to the lower mass. The drive can be disposed on the upper mass which is vibrationally decoupled from the lower mass.

In other embodiments, however, the drive can also be disposed directly on the lower mass.

The vibration decoupling device between the lower mass and the upper mass can, in particular, be a spring-damper device, for example with rubber buffers, in order to effectively isolate the vibrations produced and generated on the lower mass from the upper mass.

One roller body or the plurality of roller bodies are used for rolling over the ground in order to carry the entire ground compacting device and to be able to transport it rolling over the ground. The roller bodies can in particular be designed as wheels, wherein a plurality of wheels, in particular a pair of wheels, form a wheel set.

The electric drive, which, for example, can comprise an electric motor and can rotationally drive at least one of the roller bodies, is used to support the transport movement. By supporting the electric drive, it is easily possible for an operator to

3 EP3 901 372 move the ground compacting device on the ground using the roller bodies. The operator then only has to guide and possibly balance the ground compacting device in a suitable manner, while the actual transport movement is brought about by the electric drive and the roller bodies driven thereby.

The electric power store can in particular be a battery or an accumulator. The power store can be permanently installed in the ground compacting device.

However, it is also possible to provide the electric power store such as to be exchangeable.

In one embodiment, the running gear can be attached to the lower mass in a stationary manner, wherein the running gear is disposed at a distance to a standing surface of the compacting plate, which distance is of a length such that the ground compacting device can be tilted via the roller bodies in such a way that the compacting plate in a transportation position does not contact the ground but the roller bodies contact the ground and support the weight of the device.

However, in a working or vibrating position, i.e., when the compacting plate rests flat on the ground, the roller bodies are disposed at a certain distance from the ground. The roller bodies, so to speak, hover above the ground or contact surface.

The stationary attachment of the running gear to the lower mass means that the relative position between a running gear axle or axis of rotation of the roller bodies to the lower mass carrying the running gear, in particular to the compacting plate, is unchangeable. Although the roller bodies can rotate relative to the compacting plate, their relative position to the compacting plate cannot be changed.

Compared to devices that do not have such a running gear, the stationary running gear axle with respect to the compacting plate means that the roller bodies are in their travel position (transportation position) already during working operation (vibrating operation). Thus, extending or pivoting the running gear axle during transportation, as described in DE 198 40 453 A1, is not necessary. A particularly wear-prone part, namely an otherwise required extension or pivoting mechanism, is omitted, which results in lower acquisition costs, less downtime, lower maintenance costs and easy operability of the ground compacting device.

4 EP3 901 372

In another embodiment, on the other hand, a carrier device can be provided with which the running gear is movably fastened to the upper mass, wherein, with the aid of the carrier device, the running gear can be moved between a working position, in which the ground compacting device is able to compact the ground, and a transportation position for transportation of the ground compacting device.

The carrier device is thus used to move, in particular to pivot the running gear relative to the upper mass. In the vibrating position or working position, the roller bodies of the running gear are lifted off the ground. The running gear can be held with the roller bodies on the upper mass.

For the transportation position, the running gear is pivoted downward, so that the roller bodies can be supported on the ground and the entire ground compacting device can be transported.

The running gear can comprise at least two roller bodies, at least one roller body of which can be driven by the electric drive. Different variants are possible. It is thus possible for only one of the roller bodies to be rotationally driven, while the other roller body is mounted such as to run freely. In another variant, both roller bodies can be driven. In this case, it is possible for both roller bodies to be driven by a common drive. It is also possible for each of the roller bodies to have its own individual drive.

In one variant, the two roller bodies can be connected to each other via a torque coupling in such a way that the two roller bodies are jointly driven by the electric drive. The torque coupling can be produced, for example, by a connecting shaft, a gear, etc., in order to couple the rotational movement of the two roller bodies to one another. Accordingly, the common electric drive can be attached at a suitable location in order to transmit the torque to both roller bodies.

A controller can be provided to actuate the electric drive, wherein, by means of the controller, a readiness condition can be brought about, in which the electric drive for the running gear can be activated while the vibration exciter cannot be activated. The readiness condition means that a transport operation is possible in which the electric drive can be activated. However, no working operation (vibrating operation) is possible in the readiness condition. The readiness operation thus

EP3 901 372 constitutes a preliminary stage to the actual transport operation in which the vibration exciter must no longer be activated.

The readiness condition can be activated by a switching device, wherein the switching device can have different components or functional principles. The 5 switching device can comprise, for example, an inclination sensor to detect whether the ground compacting device is tilted about the running gear axle. If the ground compacting device is tilted about the running gear axle (axis of rotation of the wheel set or axis of rotation of the roller bodies), as described above, the roller bodies contact the ground so that the ground compacting device can be transported. This tilted or inclined condition can be detected by the inclination sensor, whereby the readiness condition can be activated.

In one variant, the switching device can comprise a drawbar detector to detect a position of a guiding drawbar in an upright stopping condition. Many ground compacting devices have a guiding drawbar with the aid of which an operator can manually guide and move the ground compacting device. For transportation, it is known to pivot the guiding drawbar upward and to lock it with the aid of a corresponding locking device, for example to latch it on the upper mass. With the aid of the drawbar detector, this stopping condition of the guiding drawbar can be detected, as a result of which the readiness condition can, in turn, be activated.

A transport operating device can be provided to activate the electric drive in at least one direction of rotation of the associated roller body and therefore transport direction of the ground compacting device. With the aid of the transport operating device, an operator can thus switch the electric drive on and off in order to bring about a rotation of the corresponding roller body (or the plurality of roller bodies) and to accomplish the transport.

For example, a rocker switch or rocker button or a control lever for forward and reverse travel can be suitable as a transport operating device, similar as in the case of an electric carriage. In this case, it can also be provided that the electric drive can be activated only when the readiness condition has been activated beforehand.

The speed of the electric drive can be constant, i.e., unchangeable.

6 EP3 901 372

In this case, operation of the electric drive is limited, for example, only to on-off or forward and reverse travel and standstill. In one variant, it is possible to vary the speed of the electric drive with the aid of the transport operating device. For example, depending on the position of the transport operating device, a higher or lower speed of the electric drive can be effected, but also a change in the direction of rotation of the electric drive.

A guiding device for manually guiding the ground compacting device by an operator can be provided, wherein the guiding device can be attached to the upper mass. The guiding device can be, for example, the above-described guiding drawbar. A vibration decoupling device can be provided between the guiding device and the upper mass for fastening the guiding device to the upper mass.

The vibration decoupling device can, for example, comprise rubber buffers.

The electric power store can be disposed on the upper mass or on the lower mass or on the guiding device. The arrangement on the upper mass and—even more so—on the guiding device has the advantage that these locations can be vibration-decoupled from the lower mass, so that the power store is exposed to only low vibrations.

The vibration exciter can be driven by an electric working drive, wherein the electric working drive is supplied with electric power from the electric power store. In this variant, the ground compacting device has a large electric drive which is used as a working drive and drives the vibration exciter. Both the electric working drive and the electric drive for the running gear are jointly fed by the electric power store.

In a fundamentally different embodiment, the vibration exciter can be driven by a combustion engine, wherein a starter battery for starting the combustion engine can be provided and wherein the starter battery forms the electric power store for the electric drive for the vehicle. In this variant, the actual working drive for the vibration exciter is provided by the combustion engine. The starter battery equipped as a battery with smaller capacitance is used to supply the starter and the electric drive for the running gear.

The power store for the electric drive can be charged by the combustion engine.

Accordingly, the power store does not have to have a large capacitance. During

7 EP3 901 372 operation, it can be charged by the combustion engine, which accordingly comprises or drives a generator.

A charging device can be provided to monitor a charge condition of the power store, wherein at least one of the following functions can be ensured: when the charge falls below a preset upper residual charge limit, switching off (or preventing a switching on of) the working drive for the vibration exciter; and when the charge falls below a preset lower residual charge limit, switching off (or preventing a switching on of) the electric drive for the running gear.

The charging device thus makes it possible to monitor the charge condition of the power store. If the power store is also used to feed an electric working drive for the vibration exciter, this working drive can be switched off when the charge falls below the preset upper residual charge limit, while at that point in time, an operation of the travel drive or electric drive for the running gear is still possible. The running gear can then be driven further while the vibration exciter is switched off.

However, when the charge falls below a preset lower residual charge limit, the electric drive for the running gear is switched off. The running gear can then no longer be driven. This measure is intended to prevent a deep discharge of the power store.

These and further advantages and features of the invention are explained in more detail in the following using examples, with the assistance of accompanying figures, in which:

Fig. 6 is a schematic bottom view of another embodiment;

Fig. 7 is a schematic bottom view of yet another embodiment; and

Fig. 8 is a schematic bottom view of a further embodiment.

Fig. 1 to 4 substantially show the same ground compacting device according to the invention as a vibration plate in each case from different viewing angles and in different operating conditions. Since the figures relate to the same object, they are also described together.

A drive belonging to an upper mass 4 and hidden under a cover 5 is positioned on a compacting plate 2 belonging to a lower mass 1, coupled via a spring damper device 3 (e.g., a rubber buffer) used as a vibration decoupling device.

The drive, usually a gasoline or diesel engine, drives a vibration exciter 6 which is coupled to the compacting plate 2 in such a way that the vibrations generated by the vibration exciter 6 are transmitted directly to the compacting plate 2 and thus into the ground to be compacted.

Alternatively, the drive can also be an electric drive and can comprise an electric motor. In this case, the drive can be disposed both on the upper mass 4 and on the lower mass 1. If the electric motor is seated on the upper mass 4, a suitable power transmission between the electric motor and the vibration exciter 6 is provided, for example a belt drive or a hydraulic drive known per se. If, on the other hand, the electric motor is disposed on the lower mass 1, it can drive the vibration exciter 6 directly.

A power store required for the electric motor can be disposed on the upper mass 4, for example below the cover 5. As a result, the power store is also decoupled from the vibrations acting on the lower mass 1.

A running gear 7 is disposed on the lower mass 1, which running gear has a running gear axle 8 which is stationary relative to the ground compacting device, about which running gear axle one or more roller bodies 9 are rotatably arranged.

9 EP3 901 372

Two roller bodies 9 designed as wheels are shown in the figures, which together form a wheel set.

In the embodiment shown here, the running gear 7 is attached to the lower mass 1, in particular to the compacting plate 2. The center of gravity distance of the overall device from the running gear axle 8 is thus reduced, as a result of which the driving behavior of the device in the transport operation is, in turn, improved.

Also, the tendency of heavy compacting plates to tilt about the running gear axle 8 and in the direction of travel during transportation is reduced.

The two roller bodies 9 can be rotationally driven by an electric motor 15 in order to facilitate transportation of the entire vibration plate by means of the roller bodies 9, which are then in contact with the ground, in the transportation position of the vibration plate. The electric motor 15 rotates the roller bodies 9, as a result of which they roll over the ground, thereby carrying the remaining ground compacting device in a rolling manner.

For this purpose, the operator can actuate a controller (not shown in the figures), for example a rocker switch or a control lever, in order to switch the electric motor 15 on and off or also to specify a direction of rotation of the electric motor 15. As a result, even heavy ground compacting devices can be easily transported in a rolling manner.

As shown in Fig. 2, the electric motor 15 can, for example, be disposed between the two roller bodies 9. It is also possible to design the electric motor 15 as a hub motor, which is then disposed in at least one of the roller bodies 9 or also in both roller bodies 9.

The running gear axle 8 can consist of an actual component; however, it can also be an imaginary axis of rotation formed by carriers 8a, 8b that are fastened to the compacting plate 2, which carriers each carry the roller bodies 9 (Fig. 2 and 4).

With a given diameter of the roller bodies 9, the axle position of the running gear axle 8 is selected such that, in a vibrating position (Fig. 3), the compacting plate 2 has flat ground contact and the roller bodies 9 do not contact the ground (distance b) whereas in a transportation position (Fig. 4) the compacting plate 2 does not

10 EP3 901 372 contact the ground (distance a), but the roller bodies 9 contact the ground and carry the weight of the device. A change between the two positions is possible by tilting the entire device about an axis which substantially corresponds to the running gear axle 8. By simply tilting the compacting plate 2 toward a drawbar 10 used as a guiding device, a change from the vibrating to the transportation position is possible here, for example. A control lever is provided on the drawbar 10, with which control lever the vibration exciter 6 can be controlled in a manner known per se.

It is furthermore advantageous to select the axle position of the running gear axle 8 and the size of the roller bodies 9 such that the distance b (Fig. 3) between a ground contact surface of the compacting plate 2 and the lowest point of the roller bodies 9 in the vibrating position, and a distance a (Fig. 4) about which the roller bodies 9 project in the transportation position from the then lowest point of the compacting plate 2 are achieved. With a sufficiently large distance a, the ground compacting device can be moved without problems even in the event of uneven ground, wherein at the same time the distance b must be selected such that it is ensured that the roller bodies 9 do not contact the ground during vibrating operation.

The running gear axle 8 is disposed above the compacting plate 2, as a result of which a favorable relationship between the line of action of the operator's tractive force at the drawbar 10, the center of gravity of the entire device and the position of the running gear axle 8 is possible so that a very good traveling comfort without tilting in the direction of travel is achieved. The ground compacting device is then balanced, so that its center of gravity is substantially perpendicular above the running gear axle 8.

Since the roller bodies 9 are also acted upon with a high acceleration when disposing the running gear 7 on the lower mass 1, in particular also on the compacting plate 2, it is recommended to provide the roller bodies 9 with a targeted imbalance 11, so that they strive to rotate about the running gear axle 8 on their own in case of vibration. In this way, selective wear of the roller body bearings is counteracted. As a result, the use of ball bearings for the roller bodies 9is particularly suitable.

11 EP3 901 372

Furthermore, the embodiment shown here has a tread surface 12 for supporting the momentum required for changing positions laterally on the upper mass 4, so that the operator can reach the driving position or transportation position, for example by weighting the tread surface 12 with the foot and tilting the drawbar 10 back and forth. This type of change from the vibrating to the transportation position, and vice versa, has a significantly lower risk of injury compared to ground compacting devices with pivotable or extendable running gears and can be performed very quickly since no conversion of the running gear is required.

The tread surface 12 can also be used as a protective cover for the electric motor located therebehind.

In Fig. 1 to 4, the drawbar 10 is pivoted upward from the otherwise usual operating position into a locking position. In this position, the drawbar can be locked by a locking device (not shown) in order to achieve a compact unit with the remaining vibration plate for transport. 15 At the same time, the position of the drawbar 10 is detected in the locking position, so that the electric drive transitions into a readiness condition.

The second prerequisite for activating the readiness condition is that the vibration plate is tilted, as shown in Fig. 4. Tilting of the vibration plate by pivoting it about the roller bodies 9 can be detected, for example, by an inclination sensor.

In this readiness condition, control elements (not shown in the figures) are activated as a transport operating device via which the electric drive can be switched on or off in order to rotationally drive the roller bodies 9 and to move the vibration plate above the ground.

Fig. 5 is a schematic bottom view of a variant of a vibration plate used as a ground compacting device.

In this case, two roller bodies 9a, 9b designed as wheels are provided, which have a common axis of rotation (running gear axle 8). An electric drive 15 is provided as a hub motor on one of the roller bodies (roller body 9a), by means of which the roller body 9a can be rotationally driven.

12 EP3 901 372

The other roller body 9b (the lower one in Fig. 5) is only mounted in a freely rotatable manner and is not driven.

A steering support may optionally be achieved by changing the speed both with respect to the speed and direction of rotation.

In one variant (not shown), both roller bodies 9a and 9b are each associated with a separate electric drive 15. The two electric drives 15 can be controlled individually in order to thus achieve maneuverability of the vibration plate. When the two electric drives 15 are operated in opposite directions, the associated roller bodies 9a, 9b also rotate in the opposite direction, so that the vibration plate can be rotated in place.

Fig. 6 shows a variant in which the electric drive 15 is likewise disposed as a hub motor in the roller body 9a (the upper roller body in Fig. 6). However, the other roller body 9b is coupled to the electric drive 15 or to the roller body 9a via a shaft 16.

Both roller bodies 9a, 9b are thus driven equally at the same speed and same direction of rotation.

In the variant of Fig. 7, the electric drive 15 is not directly associated with one of the roller bodies 9a, 9b, but is disposed approximately centrally between the two roller bodies 9a, 9b. Accordingly, the electric drive 15 can have two shaft outputs (shafts 16).

In one variant (not shown), the electric drive 15 can also have only one shaft output which is then guided to only one of the roller bodies 9a, 9b.

Fig. 8 in turn shows a different variant in which the electric drive 15 is associated only with the roller body 9a, similar as in the case of Fig. 5, while the roller body 9b rotates freely. However, the electric drive 15 is not designed as a hub motor, but as a separate motor which drives the associated roller body 9a via a transmission shaft mechanism 17.

Further drives of the roller bodies are also possible. For example, the electric drive can have a friction wheel which can be pressed onto one of the roller bodies (transport wheel).
