Definitions
- the innovation concerns a by means of a guide bracket or the like.
- Such devices which are supported on the ground with the ramming foot alone, are guided by an operator by direct transmission of executives by means of a guide bracket or a drawbar during the swinging movement of the ramming foot in the desired direction.
- the drive is switched off, the device is difficult to transport, it must be carried or driven with a suitable device, such as a cart.
- the innovation is based on the object of designing a ramming device of the type described at the outset in such a way that handling is made considerably easier, in particular the physical forces to be used for guiding it are reduced and a simple change of location is possible at any time with the tamper switched off without auxiliary devices.
- the chassis the tamper can be easily moved without additional aids even when the tamper drive is switched off. Due to the rolling support of essential weight components of the device, the necessary managers are noticeably reduced during the tamper operation. There is also the possibility of increasing the total weight of the tamper beyond the limit previously considered acceptable and, for example, of providing the tamper with a heavy diesel engine.
- a very advantageous embodiment provides that the additional chassis carries the internal combustion engine.
- Another very advantageous embodiment consists in providing the undercarriage with its own drive, a common power source preferably being provided for generating the ramming movement and the undercarriage drive.
- the self-propulsion of the undercarriage can advantageously be designed as a hydraulic drive or can take place via a drive chain.
- the chassis drive can expediently be switched between forward and reverse.
- the undercarriage can advantageously be designed as a three-point undercarriage by an additional support wheel on the side of the tamping foot facing away from the drivable axis.
- the upper mass comprises about two thirds and the striking working or lower mass a third of the total tamping mass, while the distances traveled by the upper mass and the working mass are in inverse relation to one another.
- the upper mass is in the range of 25 to 30 mm.
- This movement of the upper mass at a frequency of 10 - 11 Hz has various negative effects because these vibrations are not only transmitted to the body of the person guiding the implement over a guide bracket, especially to the hand and arm, but also because they are high There are loads on the attached drive motor regardless of its design and equally of the undercarriage provided according to the invention.
- the output of the ramming system is largely dependent on the upper mass, since too large a working mass or a too high speed of the working mass moves the upper mass oversized and increases the problems described above.
- the device In order to stabilize the upper mass without significantly increasing the weight of the device and thereby increasing the service life of the device, further improving its handling and better protecting the operator from the harmful effects of the vibrations, there is a particularly advantageous embodiment of the device according to the invention in that it Area of the upper mass is provided with a counter mass that can be driven by the motor together with the working mass, but in the opposite direction to the movement of the working mass.
- the upper mass is pressed upwards by a crank mechanism which supports itself on its housing at the moment when the crank mechanism presses the working mass and thus the ramming foot downwards via its connecting rod, a guide piston and a spring set.
- An advantageous embodiment consists in that the drive of the counter mass is derived from the crank mechanism and the movement of the end of the spring set connected to the crank mechanism and the movement of the counter mass with respect to the crank angle by 180 ° minus a phase shift derived from the design parameters of the spring set are offset from each other.
- the counter mass on the upper mass is parallel to the direction of movement of the working mass is led.
- An advantageous embodiment consists in that the counter mass is driven by a compensating eccentric on the crank mechanism, for example via a connecting rod.
- the connection between the counterweight and the compensating eccentric can be designed as a crank loop.
- the counter mass consists of two partial masses arranged on one or the other side of the crank drive at approximately the same height with respect to the axis of rotation of the crank drive, and each partial mass is connected by an eccentric pin to an associated one that is rotatably coupled to the crank drive Eccentric disc driven, the connection between the eccentric pin and the associated partial mass is designed as a crank loop.
- a further advantageous variant consists in that the counter mass consists of imbalances which are rotatably mounted on the upper mass about axes parallel to one another and are driven in opposite directions by the crank mechanism, the momentum of which and the mutual phase position are set up in such a way that they counteract an oscillation which counteracts the working mass Generate, a further embodiment consists in that the counterweight consists of two centrifugal weights, which are arranged symmetrically to the direction of movement of the working mass next to one another at approximately the same height in this direction, are rotatably coupled directly to one another and are driven by the crank mechanism.
- the counterweight consists of a first centrifugal weight seated directly on the shaft of the crank mechanism and two second centrifugal weights of symmetrical to the direction of movement of the working mass, which are arranged next to each other at approximately the same height in this direction and which have the same momentum contrary to the first centrifugal weight are rotatably driven by the crank mechanism and the moment of inertia is about half as large as the moment of inertia of the first centrifugal weight.
- the counterweight consists of a first centrifugal weight seated directly on the axis of rotation of the crank mechanism and a second centrifugal weight arranged behind it, which has approximately the same momentum as the first centrifugal weight and parallel to the axis of rotation of the crank mechanism to the direction of movement of the working mass slightly offset axis of rotation is driven in the opposite direction to the first centrifugal weight.

- the ramming tool 110b is connected approximately rigidly to the undercarriage 116b, that is to say only a slight relative movement is made possible by elastic damping members 124 and 126 between the ramming tool 110b and the undercarriage 116b, which transmit vibrations to should counteract the chassis 116b.
- the undercarriage 116b is supplemented by a third support wheel 128 to form a three-point undercarriage in order to improve stability, particularly when the ramming tool 110b is switched off.
- This third support wheel 128 is carried by an arm 130 attached to the crankcase 14 of the ramming tool 110b.
