Definitions

  • the invention relates to a vibratory rammer for soil compaction according to the type specified in the preamble of claim 1.
  • a vibration rammer of the type in question is z. B. from the DE 44 36 081 A1 known.
  • This vibratory rammer comprises a superstructure with a drive motor and a substructure with a rammer plate (or compaction plate) driven by the drive motor.
  • the tamper foot is mounted with a guide element linearly movable on the vibratory tamper, as well as the Fig. 1 of the DE 44 36 081 A1 seen.
  • An object of the invention is that of the DE 44 36 081 A1 to improve known vibration tampers.
  • a vibratory rammer for soil compaction which has a superstructure with a drive motor and a substructure with a driven by the drive motor rammer plate, wherein the rammer plate is attached to a base belonging to Stampferfuß and this Stampferfuß with (at least) a guide element is mounted linearly movable on Vibrationsstampfer.
  • the at least one Stampferfuß is integrally formed or integrally with the guide element. In other words, this means that the Stampferfuß is formed with an integrated guide element.
  • stamper is formed integrally with the guide element in one piece or integrally, the number of manufactured and to be mounted individual components over the known from the prior art constructions, such as in the DE 44 36 081 A1 shown, reduced.
  • Other advantages are the elimination of the seals between Stampferfuß and guide element, and a weight savings. As a result, a cost optimization is achieved.
  • the integrated guide element is a cylindrical or tubular inner guide of a telescopic sliding guide device. So far, such cylindrical inner guides were usually made as welded parts and then connected to the Stampferfuß, such as in the DE 44 36 081 A1 shown, which was complex and costly. In addition, both parts had to be sealed at the interface to prevent oil leakage and / or dirt entering.
  • the tamper foot has a cup-shaped section which at least partially surrounds this cylindrical inner guide. Furthermore, between the inner contour of the cup-shaped portion and the outer contour of the cylindrical inner guide, a radial gap may be present, wherein preferably in this gap at least one extending between the inner contour of the cup-shaped portion and the outer contour of the inner guide connecting web is arranged.
  • the connecting web is preferably annular or the inner guide between the inner contour of the cup-shaped portion and the outer contour of the inner guide circumferentially formed. At the level of this annular connecting web, at least one through opening can also be present, which establishes a connection between the interior of the inner guide and the outer space surrounding the rammer.
  • stampferfuß can be arranged at least one large-sized transport or handle for the vibratory rammer, said transport handle is preferably also formed in one piece or in one piece with the Stampferfuß.
  • the tamper foot as a whole, ie together with the guide element and possibly also together with the transport handle, designed as a cast construction.
  • the casting material used is primarily an aluminum material.
  • the guide element in particular compared to a steel material, can be reworked relatively easily spanabriold. Due to the less time-consuming processing a cost optimization can be achieved.
  • a casting material and a plastic material or a plastic composite material may be used.
  • the cast construction is a multi-component casting in which different casting materials are used in accordance with the requirements. So z. B. the guide element may be formed of a steel casting material, while the rest of the Stampferfuß consists of an aluminum material.
  • Fig. 1 1 shows a superstructure 2 with a drive motor 3 and a substructure 4 with a tamper base 5, to which a tamping plate 6 is fastened.
  • the drive motor 3 drives an eccentric 7, on which a connecting rod 8 is mounted, which is connected at its lower end via prestressed springs 9 and 10 with the Stampferfuß 5.
  • the tamper foot 5 is mounted in a linearly movable manner on the vibration tamper 1 by means of a telescopic sliding guide device, this telescopic sliding guide device comprising a cylindrical inner guide 11 and a likewise cylindrical outer guide 12, which form corresponding guide elements (inner guide element and outer guide element).
  • the upper end of the cylindrical inner guide 11 is referred to, which also serves as the upper abutment for the spring 9.
  • a flange on the superstructure 2 is designated, on which the outer guide 12 of the telescopic sliding guide device is attached. To protect a bellows 15 is provided.
  • stamper foot 5 is integrally formed or integrally with the cylindrical inner guide 11, which in the following in connection with the Fig. 2 is explained in more detail.
  • Fig. 2 shows the designed as a cast design Stampferfuß 5, wherein the cylindrical inner guide 11 is formed integrally with this Stampferfuß 5.
  • the tamper foot 5 has a cup-shaped portion 16 which surrounds the cylindrical inner guide 11 in the lower region. Between the inner contour of this cup-shaped portion 16 and the outer contour of the cylindrical inner guide 11, a radial or annular cylindrical gap 17 is formed, on the one hand movement space for the outer guide 12 is created and on the other hand, the access for processing tools to the outer surface of the inner guide 11 is made possible to be able to process these by machining.
  • annular Connecting web 18 is arranged, whereby a particularly stable structure is achieved.
  • a through hole 19 which establishes a connection between the interior of the inner guide 11 and the outer space surrounding the rammer 1.
  • the through hole 19 is closed in the cup-shaped portion 16 with a locking screw 20.
  • the connecting web is further formed as a pocket 21, whereby this particular area is additionally stabilized. All transitions are designed to be castable and optimized for stress.
