Definitions

  • the invention relates to a vibration plate according to the preamble of claim 1.
  • Vibration plates of this type are known from DE-OS 16 34 492.
  • Vibration plates of the type characterized in the preamble of claim 1 generally have the advantage that a substantial area of the base plate is always underlaid by a tape, so that the base plate does not stick there, at least in the vibration mode, due to the lack of direct contact with the compaction material even if it is in vibration mode is binding. Therefore, the bottom plate may at any time independently of the loose soil under the vibrational forces from their support, is thus ensures the condition for the easy movement of the vibrating plate in the direction of travel under all operating conditions in the V ibrations ses. As the vibrating plate moves, each tape in the lower run, with the underside possibly adhering to a cohesive surface, is "peeled off" from this behind the trailing end of the base plate, which requires only very little effort.
  • the deflection devices are designed as driven rollers which are in frictional engagement with the only belt there.
  • unfavorable operating conditions e.g. greasy contamination of the side of the tape facing the rollers and the rollers, it can happen that the frictional engagement is practically eliminated and the rollers then slip through the tape.
  • the problem underlying the invention is to design vibration plates according to the preamble of claim 1 so that even under unfavorable Operating conditions, a safe transport of the belt or the belts is guaranteed solely by the travel drive, ie when the vibration exciter is switched off, and that no swirled compaction material can get stuck between the belt and the base plate, and that thin belts can still be used.
  • the perforation in the form of the band openings has a double function.
  • the first function is that it enables the travel drive to positively engage in a band, which can nevertheless be made thin
  • the second function is to create through-openings for swirled compaction material from the space between the band and the base plate Tape and soil compaction plate out through the tape back to the floor.
  • the thin tape with its advantage of good conformability and transferability for the vibrational forces, remains fully intact and is not replaced by the link-like structure known from tracked vehicles.
  • Subclaims 2 to 11 relate to preferred configurations of the vibrating plate according to claim 1.
  • Subclaims 7 to 11 have features that relate to the structural design of the band or bands.
  • the bands are subject to a considerable load, under which they should not expand significantly, while they should, as far as possible, hug the floor compaction plate as evenly as possible and also be as flat as possible towards the ground, so that a largely uniform force is applied to them for soil compaction can be transferred as with a normal vibratory plate.
  • the features mentioned in subclaims 7 to 11 characterize a belt construction that fully meets the aforementioned requirements and is nevertheless distinguished by a long service life and reliability.
  • the forces which are introduced into the belt by the positive-locking elements provided, for example, on the drive roller or drum of the travel drive of the vibrating plate, are transmitted over a large surface into the plastic and are largely evenly distributed.
  • the tensile cord or the tensile cords ensure the longitudinal stability of the band and the necessary uniform, unchangeable distance between the openings which are congruent with the recesses in the cross pieces.
  • Tapes with the features according to subclaims 7 to 11 can be produced using flat cross pieces with a relatively small thickness and can be set up very flexibly and are nevertheless highly resilient.
  • the vibration plate shown in FIGS. 1 and 2 has a base plate 1 which extends between solid side plates 2, which are connected to one another via a cross plate 3.
  • a vibration exciter 4 e.g. an unbalance exciter, which in the present case generates a directional vibration with a direction of vibration vertical to the base plate.
  • the rollers 5a and 6a are divided in the longitudinal center and by a rotary drive, not shown, possibly provided inside, e.g. a hydraulic or electric motor, independently of each other can be driven clockwise and counterclockwise.
  • the rollers 5a and / or 6a could be driven from the same power source, e.g. an internal combustion engine, which is responsible for driving the vibration exciter 4.
  • An endless belt 8 is guided over the deflection rollers 5a and 6a on one side of the vertical longitudinal center plane L of the vibrating plate and over the rollers 5a and 6a on the other side of this longitudinal center plane, that with its lower run under the base plate 1 and with it upper strand extends over it.
  • the strips 8 have a perforation 9 which extends in their longitudinal direction and matches the strip-like form-locking elements 7 of the rollers 5a and 6a, into which the form-locking elements 7 engage.
  • the aforementioned parts together form the lower mass of the vibrating plate, on which the upper mass (11), which is the spring source (11), is placed, which is the power source 12, for example one Combustion engine, for the various components to be driven in the vibration plate according to the invention, such as the vibration exciter 4 and the deflection rollers 5a and / or 6a, and the hydraulic oil tank 13.
  • the oversize 11 loads the undersize, which vibrates towards it under the action of the vibration exciter 4 and compresses the subsoil via the base plate 1.
  • the base plate 1 is in this case not in direct contact with the substrate but indirectly via the endless belts 8, which transmit the compaction performance over the entire surface of the base plate 1 into the substrate. Because of the perforation 9, the tapes 8 are also particularly easy to grip, without their good slidability with respect to the base plate 1 being impaired or compacted material being able to settle in between.
  • the belts rest in the area of the base plate 1 on the ground, and the latter is due to the forced driving of the belts by the rollers 5a and / or 6a on the lower run of the belts, depending on the direction of rotation of the rollers for the viewer Fig. 1 forced to the left or right as long as the rollers have the same direction of rotation, or rotated with respect to the ground on the spot when the rollers 5a, 6a on one side of the longitudinal median plane L on the one hand and the related roles on the other Side of this level L are driven in the opposite direction.
  • the rollers 5a and / or 6a or for the belts 8 ensure that the base plate 1 detach from its base even under cohesive soils under the vibrational forces and can then be easily moved in the direction of travel.
  • the forward movement of the vibration plate could also be brought about solely by the vibration exciter 4 by means of a vibration component in the direction of travel of the vibration plate.
  • the compulsory traction drive via the belts 8, however, has various special advantages.
  • a vibration exciter can be used which generates a directional vibration with a direction of vibration perpendicular to the base plate, that is to say without loss of power due to any propulsion component in the direction of travel.
  • the positive drive ensures a particularly high gradeability.
  • the finished strip 8 according to FIG. 4 is formed by inserting the metal insert according to FIG. 3 into a mold after completion, in which it is then extrusion-coated with an abrasion-resistant elastic plastic, preferably polyurethane, with the breakthroughs discussed in more detail below, or /
  • Figures 5 and 6 show the metal insert for two further embodiments of tapes according to the invention. These metal inserts, like those according to FIG. 3, are extrusion-coated with the plastic after the openings have been left open. Since, based on FIG. 4, it is readily conceivable what the finished endless strips with the metal inserts according to FIGS. 5 and 6 look like, an additional representation can be dispensed with.
  • the metal insert 8 2 consists of at least one flexible tensile strand 83, which extends in the longitudinal direction of the endless belt, and a plurality of flat, rigid cross pieces 8 4 which are perpendicular to the tensile strand or the tensile strands 8 3 , ie perpendicular to the longitudinal center line of the finished endless Tape, at a uniform distance from the tape openings 8 5 (Fig. 4) are attached.
  • the embodiment according to FIGS. 3 and 4 three such pull strands are provided, the embodiment according to FIG. 5 has two pull strands 8 3 , and the embodiment according to FIG. 6 is equipped with a single pull strand 8 3 .
  • tension cords 8 3 s y MME are arranged symmetrical to the longitudinal center line of the strip. 8
  • the recesses 8 6 are each symmetrical to the longitudinal center line of the finished strip between the adjacent pull strands 8 3 in the cross pieces 8 4 , so that in the embodiment according to Fig 3 and 4 result in two rows of perforations and in the embodiment according to FIG.
  • the tensile strands 8 3 hold the cross pieces 8 4 securely at the predetermined distance and distribute the tensile force to the individual cross pieces 8 4, which in turn introduce them over a large area into the plastic strip. In this way, despite the achievable small thickness of the band 8, excellent band stability is achieved both in the transverse and in the longitudinal direction of the band.
  • the metal inlays 8 2 are preferably made of steel, the tension cords 8 3 are made of spring steel.
  • Polyurethane is particularly suitable as an abrasion-resistant, elastic plastic.
  • connection between the cross pieces 84 and the tension cords 8 3 is made in any suitable known manner, for example by spot welding or riveting.
  • a material could also be used for the insert 8 2 which, in terms of its resilience, in particular its extensibility, has properties similar to those of the metals which can reasonably be used, in particular steel.
  • the perforations 9 in the band 8 of the vibrating plate according to FIGS. 1 and 2 or the perforations 8 5 forming these perforations in the band version according to FIGS. 3 to 6 convey the advantage, in addition to the functions described above, that the grip of the tape or tapes 8 on the ground is increased considerably by them, which also has a very positive effect on the climbing ability of the vibrating plate on sloping terrain.
  • the vibrating plate can be built in any size and, in the case of smaller versions, can also be provided with a guide drawbar if - in the case of such a simple version - cornering by means of split belts of switchable running direction is not provided.
