Description

self-moving

The invention relates to a

Vibration compressors for directional or non-directional Vibrations, especially for soil compaction.

There are known working with directional vibrations vibration compressors in which the directional Vibrations are generated by counter-rotating imbalances and by a horizontal one Component of the vibrations causes a feed of the device. By changing the direction of oscillation the feed speed can be changed or the direction of movement can even be reversed will. A steering takes place here by the fact that the device by muscle power on a guide rod being pushed around.

It is also a self-moving mechanical device by a circular oscillator known in which the circular oscillator with its drive motor is supported by slightly inclined leaf springs on runners is lying on the floor. As a result of the elastic resilience of the springs, a Asymmetry, which results in a hopping forward movement of the device. With this well-known Device is a steering by mutual displacement of each other resiliently supported Masses caused or by coupling two such devices in series for steering purposes can be twisted against each other. The first type of steering is not very effective, so that it is not useful for many purposes where great mobility is required. The second kind the steering requires large steering forces and a considerable mechanical effort.

Furthermore, a soil compactor with a circular vibrator is known, in which the circular vibrator Masses are resiliently coupled in such a way that.ge-, -richtete Vibrations arise. By pivoting the circular oscillator with the masses by one horizontal axis, a more or less large horizontal transport component can be set. This also only allows a change or reversal of the feed rate to be achieved. but no steering. The steering takes place here as with the first-mentioned devices by means of a Guide rod.

It is also known, in a soil compactor, a feed and a reversal of the direction of movement to be effected by additional weights, which can be moved in the longitudinal direction of the device. Even with this arrangement, however, no steering of the vibrator is provided.

The invention has for its object to provide a soil compactor, which with relatively simple Adjusting means allow steering, d. H.

can automatically describe a curved path without pushing around or guiding by hand. This is achieved according to the invention in that to generate the necessary to steer the device Torque at least one vibration exciter around one to the axis of rotation of the unbalances vertical axis swiveling or a vibration exciter sideways to the center of gravity of the device is displaceable, or that several. Vibration exciter laterally and asymmetrically, to the center of gravity of the device can be moved.

The rotation or lateral displacement of the vibration exciter is with. little effort and possible without excessive adjustment forces. The result is good maneuverability, which is particularly important for soil compactors of great importance on smaller construction sites, j

Fig. 4 and 4 a show a front view and a top view of such a compressor with an unbalance vibrator.

In the embodiment according to Fig. 1, la and Ib, two unbalanced vibrators 2 and 3 are arranged one behind the other on a compression plate 1. The vibrators 2, 3 with the unbalances U rotate about axes perpendicular to the longitudinal axis of the device and are mounted in frames 4 and 5, which in turn are pivotably mounted in stands 6, 6 'and 7, T about a horizontal longitudinal axis HA . By tilting the frames 4, 5 asymmetrically or in opposite directions in the direction of arrow A or B (Fig. 1 b), a steering movement of the vibrating device can be achieved.

In the embodiment according to Fig. 2 and 2a, a drive motor M is arranged at the location of the vibrator 3 and its bearing parts S ₁ 7, T. With such a vibrator, too, steering can be achieved by pivoting the frame 4.

The embodiment according to Fig. 3, 3a and 3b also shows two vibrators 2, 3 arranged one behind the other on a compression plate 1, which are mounted here in stands 8, 8 ', 9, 9'. The stands 8, 8 'and 9, 9' are arranged on base plates 10 and 11, respectively, which can be rotated in the direction of the arrow (Fig. 3a) about a vertical axis VA (Fig. 3 and 3b).

In the embodiment according to Fig. 4 and 4 a, the vibrator 3 is replaced by a drive motor.

The center of gravity of the device is denoted by S in each case.

If a shaker is rotated around an axis HA or VA, the centrifugal force creates a component in the horizontal plane that is perpendicular to the main direction of movement. If, therefore, in Figs. 1 and 3, the two vibrators are rotated or tilted in opposite directions, a couple of forces is created each time, which enables the necessary rotation of the unit and thus the steering. Here, the frictional forces between the floor and the plate play a role and, in particular, when rotating around the horizontal axis HA, the forces that oppose the desired steering find their reaction in the floor and thus do not allow any movement or rotation in the undesired sense. This applies both when the plate 1 lifts off the ground and when the plate and thus the assembly only perform sliding movements. In the examples according to Figs. 2 and 4, the second force belonging to the force couple arises from frictional forces between the floor and the plate.

Circular vibrators are shown in the figures. Anyone else can take their place Vibrators with a similar effect occur. There is still the possibility of a torque to be generated by lateral displacement of the vibration exciter (s).

Rotating, tilting or moving the or the shaker has the further advantages that a Steering of vibrating devices can also be achieved with undirected vibrations and that with special Execution only a single imbalance is required.

In the method for steering with the help of a rotation of the vibration exciter (s) by one to the Axis of rotation at an angle, the drive of the unbalances can be conveniently carried out in the following way carry out. The one pivot of the frame in which the unbalance (s) is (are) is designed as a hollow pin. The drive shaft for the imbalance (s) goes through this hollow pin.
