Definitions

  • the invention relates to a method for fastening a machine base of a machine according to claim 1 and to a fastening device for a machine base according to the preamble of claim 7.
  • Foundation anchors are usually used to fasten machines or other components to their foundations, which are usually prefabricated from concrete.
  • the anchor bolts or bolts used are anchored with their heads in the foundation, and the machine to be fastened is attached to the shaft of the machine base using screws.
  • the foundation anchors, especially of large machines, must be designed for the direct transmission of very large forces (usually accident forces) and prevent the machine from being lifted off the dation.
  • compensating elements must be provided in order to be able to align the machines or an entire machine set.
  • Such foundation anchors are for example from the documents CH-PS-501, 163, DE-A1-42 27 924, DE-A1-41 39 387, CH-A5-676 876, DE-C1 -44 03 442, US-A- 5,289,626, DE-A1-43 35 485, US-A-1, 380,347, US-A-2,954,647, US-A-3,401, 733, DE-A1-100 09 072, DE-OS-25 24 682 or from DE -OS-2 011 468 known.
  • the document DE-OS-2 304 132 offers a solution for anchoring an anchor bolt in the foundation and bracing the machine foot.
  • a spatially adjustable support which is height adjustable and at the same time is equipped with a swivel screw for leveling.
  • the support is poured into the foundation.
  • the anchor bolts protrude from the foundation during assembly. These are in the way during the installation of the machine. There is also a risk of injury due to the protruding anchor bolts.
  • the present invention seeks to avoid the drawbacks known from the prior art.
  • the invention solves the problem of creating a method for fastening a machine foot and additionally fastening a machine foot, which is characterized by a simple construction.
  • the main aim of this is to reduce the complexity of the fastening and thus to shorten the overall assembly time.
  • the object is achieved in a method for fastening a machine base according to claim 1 in that it has the following method steps
  • End of the foundation anchor is designed such that it forms a stop in interaction with the foundation box
  • Machine foot is passed through.
  • the foundation anchor is advantageously already lowered when the foundation is poured into the foundation box, so that the casting and the subsequent installation of the machine are in no way impaired.
  • the actual assembly is then carried out via a threaded rod, which engages through the machine base and the means for height adjustment and the means for evenness to the upper part of the foundation anchor. In this way, the anchor bolt can be pulled up.
  • the foundation anchor can be pre-tensioned hydraulically or by a torque wrench.
  • the means for height adjustment and flatness compensation continue to be independent of the foundation, no further adaptation to the foundation, for example during casting, and further processing of the foundation plate is advantageously required.
  • the means can simply be positioned on the foundation plate above the hole for the foundation anchor during assembly.
  • the object is also achieved by a bearing block produced by the method according to the invention in accordance with the preamble of claim 7 in that the means for height adjustment of the machine base and the means for leveling the machine base are placed on the surface of the foundation independently of the foundation.
  • Fig. 1 shows a foundation of a machine in which a foundation box with an internal foundation anchor is cast
  • Fig. 2 shows the foundation of the machine while anchoring the machine base
  • Fig. 3 shows the detail m of Figure 2 and
  • Fig. 4 shows the foundation anchor in the assembled state.
  • a method for fastening and for leveling a machine base 9 of a machine on a foundation 1 and a corresponding fastening device are disclosed. Both are explained in more detail with reference to the attached Figures 1 to 4.
  • the machine to be fastened is a thermal turbo machine or parts, that is to say, for example, a gas or steam turbine, a compressor, a generator or a transmission.
  • the present invention is in no way limited to this.
  • a foundation box 3 is poured into the foundation 1 before setting up the machine.
  • a foundation tanker 4 is located within the foundation box 3. It is also conceivable that a holding rod is used during the casting and alignment of the foundation box 3 and that the holding rod is only replaced later by the actual foundation anchor 4.
  • the foundation anchor 4 has a threaded nut 5 at the lower end.
  • This threaded nut 5 forms, in interaction with the foundation box 3, a counter bearing or a stop, so that after the fastening has been carried out, the machine foot 9 can be braced.
  • the lower threaded nut 5 is secured against twisting by positive locking with the foundation anchor 4 in the foundation box 3.
  • a square nut can be used as the counter nut 5, it cannot be rotated, and the foundation anchor 4 can also be easily mounted using a torque wrench.
  • the foundation anchor can also be hydraulically preloaded. Since the foundation anchor 4 is lowered at this stage of assembly in the foundation box 3, the installation of the machine is advantageously not affected in any way.
  • a foundation plate 2 made of steel is placed on the surface of the foundation 1.
  • the foundation plate 2 serves as a support for the machine.
  • means for height adjustment 7 and means for leveling 6 are arranged above the foundation anchor 4 on the surface of the foundation plate 2 above the foundation box 3.
  • the means for height adjustment consist of a threaded bushing 7 and the means for leveling form two spherical washers 6.
  • the two spherical washers 6 have a spherical surface at the point of contact, so that a mutual displacement leads to a certain level, which compensates for the level of the machine foot to the level of the foundation plate ,
  • the spherical washers 6 are advantageously equally accessible from all sides.
  • the machine foot 9 is placed on the means mentioned.
  • the spherical washers 6 have a thread 8 directed towards the foundation anchor 4, which is connected to the threaded bushing 7 for the purpose of height adjustment. These means are therefore independent of the foundation 1 and do not require any adaptation to the foundation 1 (eg when casting) and no further processing of the foundation plate 2. They can simply be positioned on the foundation plate 2 above the hole for the foundation anchor 4 during assembly.
  • the foundation anchor 4 is then pulled up out of the foundation box 3 via a threaded rod 10 through the spherical washers 6 and the threaded bushing 7 and through the machine base 9, as shown in detail EI in FIG. 3. Both the spherical washers 6 and the threaded bushing 7 are arranged concentrically around the foundation anchor 4.
  • the last method step of fastening the foundation anchors 4 is prestressed by an upper threaded nut 11 and, after the prestressing, the threaded nut 11 is secured against loosening.
  • a washer 12 is additionally placed under the threaded nut 11.
  • Another advantage of the fastening according to the invention is that the foundation anchor 4 can be easily replaced if this should be necessary.

Abstract

L'invention concerne un dispositif de fixation d'un pied (9) d'une machine à une fondation (1). Ce dispositif comprend un tirant de fondation (4) qui serre la machine contre la fondation (1). Une section moyenne s'étend entre l'extrémité du tirant de fondation (4) solidement ancré dans la fondation (1) et l'extrémité du tirant de fondation traversant le pied (9). En plus, un moyen de réglage en hauteur (7) du pied (9) et un moyen d'équilibrage de planéité (6) du pied (9), situés sur la surface de la fondation (1) au-dessus d'une plaque de fondation (2), sont placés de manière concentrique autour du tirant de bâti (4). L'invention concerne un procédé de fixation et de nivellement du pied (9).
