Description

Auf der Oberplatte 1 ist mit Hilfe des Schwenklagers 11, des Bolzenlagers 17 und des Gewindebolzens 14 die Motorplatte 13 verstellbar befestigt. Auf dem Gewindebolzen 14 sind Flügelmutter 15 und Mutter 16 aufgeschraubt. Der Elektromotor 12 (Figur 1) oder der Verbrennungsmotor 18 (Figur 2) sind je auf einer Motorplatte 13 befestigt.On the top plate 1, the motor plate 13 is adjustably mounted by means of the pivot bearing 11, the pin bearing 17 and the threaded bolt 14. On the threaded bolt 14 wing nut 15 and nut 16 are screwed. The electric motor 12 (FIG. 1) or the internal combustion engine 18 (FIG. 2) are each mounted on a motor plate 13.

Sowohl der Verbrennungsmotor 18 als auch der Elektromotor 12 sind auf gleichartige Grund- oder Motorplatten 13 montiert. Beide Motorplatten 13 sind mit den darauf montierten Antriebsmotoren 12 bzw. 18 zum gegenseitigen Austausch eingerichtet. Bei Motorwechsel wird die Flügelmutter 15 gelöst. Der Gewindebolzen 14 der Flügelmutter 15 ist schwenkbar im Bolzenlager 17 gelagert und kann dann aus dem Schlitz der Motorplatte 13 herausgeschwenkt werden. Die Motorplatte 13 wird dann an dem im Schwenklager 11 lagernden Zapfen entsichert, und nach Abheben des Keilriemens 4 vom Motor 12 bzw. 18 kann die jeweilige Motorplatte 13 mit dem entsprechenden Motor 12 bzw. 18 ausgewechselt werden, z.B. Elektromotor 12 gegen Verbrennungsmotor 18 oder umgekehrt. Nach Wechsel der Motorplatte 13 vollzieht sich der Vorgang der Montage in umgekehrter Reihenfolge, die Motorplatte 13 wird mittels Steckzapfen und Splintsicherung sowie mit einklinkbarer Flügelmutter 18 befestigt. Mit Hilfe der Mutter 16 kann der zwischen Motor 12 bzw. 18 und Vibrator 3 vorhandene Keilriemen 4 gespannt werden. Die Inbetriebnahme bei Elektrobetrieb erfolgt mittels eines Drehrichtungs-Umkehrschalters, so daß eine Umpolung der Anschlußklemmen grundsätzlich entfällt. Der Anschluß an das Stromnetz erfolgt über einen Aufbaustecker. Der Betriebsschalter 9 verhindert einen unbeabsichtigten Drehrichtungswechsel, durch falsches Polen der Kontakte R, S oderT. Durch den auf der Schwingplatte 2 montierten Vibrator 3 werden die Impulse in den Boden eingeleitet, die zu einer dichteren Lagerung der einzelnen Masseteilchen führen.Both the engine 18 and the electric motor 12 are mounted on similar base or engine plates 13. Both motor plates 13 are arranged with the drive motors mounted thereon 12 and 18 for mutual exchange. When changing the engine, the wing nut 15 is released. The threaded bolt 14 of the wing nut 15 is pivotally mounted in the pin bearing 17 and can then be pivoted out of the slot of the motor plate 13. The motor plate 13 is then released on the pivot bearing 11 in the journal, and after lifting the V-belt 4 from the engine 12 and 18, the respective motor plate 13 with the corresponding motor 12 and 18 are replaced, e.g. Electric motor 12 against internal combustion engine 18 or vice versa. After changing the motor plate 13, the process of mounting takes place in reverse order, the motor plate 13 is secured by means of plug pin and cotter pin and with einklinkbarer wing nut 18. With the help of the nut 16, the V-belt 4 present between the motor 12 or 18 and the vibrator 3 can be tensioned. Commissioning in electrical mode by means of a reversing switch, so that a reversal of polarity of the terminals is basically eliminated. The connection to the power grid is made via a body connector. The operation switch 9 prevents inadvertent rotation change by incorrectly polarizing the contacts R, S or T. By mounted on the vibrating plate 2 vibrator 3, the pulses are introduced into the soil, which lead to a denser storage of the individual mass particles.

Gemäß Figur 2 wird der Vibrator von einem Verbrennungsmotor 18 angetrieben, der schwingungsgeschützt auf der Motorplatte 13 montiert ist. Die Antriebsleistung des Motors 18 wird über eine Fließkörperkupplung mittels Keilriemen 4 auf den Vibrator 3 übertragen. Die Fortschreitbewegung erfolgt je nach Art und Feuchtigkeitsgehalt des zu verdichtenden Untergrundes. Die Erregerfrequenz kann durch eine Änderung der Motordrehzahl dem Boden angepaßt werden. Die Motorplatte 13 mit dem Verbrennungsmotor 18 und der Führungsstange 6 ist durch Schraubfedern 5 mit der Schwing platte 2 derart verbunden, daß sie beim Arbeiten relativ ruhig bleibt und somit der Motor 18 und die Bedienungsperson vor Schwingungen geschützt werden.According to FIG. 2, the vibrator is driven by an internal combustion engine 18, which is mounted vibration-proof on the motor plate 13. The drive power of the motor 18 is transmitted via a floating body coupling by means of V-belt 4 to the vibrator 3. The progressive movement takes place depending on the type and moisture content of the substrate to be compacted. The exciter frequency can be adapted to the ground by changing the engine speed. The motor plate 13 with the engine 18 and the guide rod 6 is connected by helical springs 5 with the swing plate 2 such that it remains relatively quiet while working and thus the motor 18 and the operator are protected from vibration.

Field of application of the invention

The invention relates to a vibrating plate and is used for compacting and solidifying the subsoil. The compaction effect is based on the principle of vibration and is thus dependent on the grain composition of the soil to be compacted, its moisture content and the type of substrate.

Characteristic of the known technical solutions

Vibrating plates or devices are known which work either with an internal combustion engine or only with an electric motor and are used for compaction and solidification of the building surface. In vibration plates with internal combustion engine, this is mounted on a top plate, and the top plate is resiliently connected to a vibrating plate. On the swing plate a vibrator is attached. Vibration plates, which work with internal combustion engine, have the disadvantage that they are maintenance-intensive and not environmentally friendly. In addition, the fuel consumption plays a certain role.

Environmentally friendly, however, are vibration plates that have an electric motor as a drive unit and work to save fuel. The disadvantage of these vibrating plates is that they are dependent on cable and bound to existing electrical connections. A special type of vibration plates with internal combustion engine have become known from DE-OS 2321761 and DE-AS 2407730. The internal combustion engine is located on the ballast and drives a generator. The vibrator is driven by a pole-changing and reversible electric motor also mounted on the swing plate. The electric motor works with the electrical energy generated by the generator. In addition to the disadvantages mentioned above is added that the cable connection between the generator and the electric motor is subject to vibrations due to the vibration and leads to cable breaks.

Object of the invention

It is the object of the invention to minimize the changeover times when changing the drive units.

Explanation of the essence of the invention

The invention has for its object to provide a vibrating plate, which can be operated according to the given site conditions both with internal combustion engine and with electric motor. According to the invention this object is achieved in that both drive units are mounted on a respective base plate, and because of their mounting elements, the drive units are easily and quickly interchangeable. The cumbersome assembly effort when replacing conventionally mounted units with resulting adjustment work is avoided.
Due to the additional mounting of an operating switch eliminates the need for polarity reversal of the plug in electrical operation.
