    Seismic leveling device with partially spherical top and bottom nut and application
    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a leveling assembly comprising a column which can be mounted at an upper end to a workpiece such as a machine, and which is mounted at a lower end in a foot, the leveling unit further being provided with a clamping device which can lock the column by clamping position relative to the foot
    In addition, the invention relates to the use of the leveling assembly.
    From PCT / DK2014 / 050288 there is known a leveling unit which can be used to support machines in earthquake threatened areas.
    The machine foot known from PCT / DK2014 / 050288 is characterized in that the column is fastened to the foot with a bolt which is mounted from the underside of the foot and fastens the column by tightening in an internal thread with the column at the lower end, which faces the foot.
    However, it has been found that there are some drawbacks to this prior art, including that the internal threaded hole provided in the column which is used to ice the fastening bolt will impair the ability of the column to withstand force. According to the prior art, the column above the foot has an outer abutment in the form of an outward flange and an outer top nut arranged between the flange and the foot, so that compressive force from the column is transferred to the foot via the flange and the top nut, and traction between the foot and the column is transmitted via the fastening means. bolt.
    It is therefore an object of the invention to provide a technique without the above disadvantages. Another purpose is to provide an alternative
    DK 2017 70114 A1 technique.
    The object of the invention is met by a leveling assembly of the type specified in the preamble of claim 1, which is characterized in that the lower end of the column is inserted into the foot and fastened to it by tightening a bottom nut which is at an upper end complementary to it. contact surface of the foot that the bottom nut will touch upon tightening.
    In this way, it becomes possible to maintain the column's ability to withstand forces of force, since the column is not weakened by an internal threaded hole.
    As stated in claim 2, the thread about the lower end of the column is raised over the foot, with the thread being coupled with an internal threaded nut having a flange projecting from the bottom edge of the thread, which flange has an interior, as part of a thread. ball-shaped abutment surface, adapted for abutment to a corresponding exterior as part of a bullet-shaped abutment surface on the upper side of the foot around an opening through which the lower end of the column is passed. Here, the term "shell" means a surface which, in accordance with the manufacturing methods used for the workpieces, is closest to a spherical surface. Hereby, the top nut will act as a tightening device, so that tightening between the bottom nut and the top nut can be provided by adjusting the top nut. The top nut transfers compressive force to the foot via its downwardly facing abutment, and via the column passage down through a hole in the top of the foot and the bottom nut abutment towards the inside of the foot, it becomes possible to transfer traction to the foot, corresponding to the entire column's bearing capacity, since the column without significant reduction in diameter is brought down into the foot. This is of great importance in areas with earthquakes, where there is a risk of fine-tuning equipment being thrown into the air as a result of the strong movements of the substrate, unless proper fasteners are used against
    DK 2017 70114 A1 substrate, which will also withstand strong drag. By allowing the column to be inserted into the full-diameter foot, it becomes possible to utilize the entire column's carrying capacity, also in relation to pull-up of the foot.
    Furthermore, as stated in claim 3, it is a particular feature of the invention that the upper end of the bottom nut is partially spherical.
    This results in, for example, that the column can be moved relative to the foot. The column coupling to the foot is thus in fact designed as a ball joint, and it arises from the fact that the opening in the foot has a slightly larger diameter than the outer diameter of the column's lower thread piece, a movement so that the column can tilt or rotate about any horizontal axis through the center of the partially spherical joint portions: the top of the foot around the opening and the underside of the nut, as well as the inner surface of the foot around the opening and the bottom of the bottom nut. It is assumed here that the partially spherical joint members are all arranged so that they have a common geometric center.
    As stated in claim 4, the bottom nut is formed with a through-hole, so that the bottom nut can easily be mounted on the lower part of the column via its external thread. Hereby it becomes possible to adjust the distance between the bottom nut and the top nut both via the underside of the foot and via the outer surface of the top nut, which for this purpose can be formed with engagement means, for example in the form of pairs of planar parallel opposite external surfaces.
    As stated in claim 5, it is also preferred that the bottom end of the bottom nut is planar, so that the bottom nut has no parts extending below the lower end of the column when the bottom nut is mounted thereon with full threaded engagement.
    DK 2017 70114 A1
    As stated in claim 6, the height of the bottom nut is minimized, however, it must always be ensured that between the inner thread of the bottom nut and its spherical abutment towards the inside of the foot is sufficient material to transmit the tensile forces that occur when the column carries its maximum weight in an earthquake affected area. . This applies regardless of the angle of rotation or tilt that the column may take relative to the foot.
    It is advantageous, as stated in claim 7, if the bottom nut is provided with both tightening facilities and fixing facilities. Tightening facilities are defined as engagement surfaces which enable the bottom nut to be exposed to an external torque from a tool having engagement means corresponding to the tightening facilities of the bottom nut. For example, it may be 2, 3 or more holes provided in the surface of the bottom nut facing the environment, which allow a tool with a torque arm and the engagement portion corresponding to the holes to tighten the bottom nut with a suitable torque, so that the foot goods between the bottom nut and the top nut are clamped therebetween. There should further be a through-hole from the underside of the bottom nut to its inner thread surface so that a pin screw can ensure that the bottom nut does not detach from a tightened position due to shaking.
    In the event that the leveling unit is to be used in areas where special hygiene requirements are set, the unit as provided in claim 8 must be provided with gaskets so that there are no cracks and cracks that could be invaded by bacterial or dirt coatings. For example, the top nut must have gasket against both the foot and the column. Also other loose parts, such as the casing shown for protecting an upper thread, must include gaskets, partly against a machine and partly against the smooth part of the column itself under the upper thread piece. Finally, possible screws or bolts for attachment to the ground must also be fitted with gaskets between the bolt heads and the foot
    DK 2017 70114 A1 top side.
    As also stated in claim 9, the column must be inserted into the foot via a centrally located aperture herein, with a vaulted portion arranged around the aperture to enclose the bottom nut. Here, the vaulted portion is surrounded by a flange with an upper side and an underside, the underside extending along a plane, the plane of which remains unbroken by the bottom nut and the column regardless of the angle of the column with respect to the foot. Further, through the flange, openings are arranged between the upper and lower sides for the purpose of mounting the foot against a support. These measures together ensure that the foot and thus the column can be securely mounted against a substrate and that the column can then be rotated to an appropriate angle with respect to the surface of the substrate without colliding with a base plate arranged along the plane.
    As mentioned, the invention also relates to the use of the leveling assembly for areas at high risk of severe vibrations including earthquakes. The application here provides the opportunity to secure machines from being moved around or directly thrown into the air from the ground during an earthquake.
    The invention will now be explained in more detail with reference to the drawings, in which:
    FIG. Figure 1 shows a partially cut-away view of a leveling assembly with a device for fixing column 1 and foot 5, with column 1 attached to foot 5 using a partially spherical bottom nut 4.
    FIG. 2 shows an enlarged sectional view. First
    FIG. 3 is a sectional view of a leveling assembly provided with a partially spherical base nut 4, which can be locked to the column 1 with a pin screw
    8th
    DK 2017 70114 A1
    FIG. 4 is an enlarged sectional view, partially cut away, of an example of the invention.
    Figures 1-4 show a leveling assembly comprising a column 1 which is provided at the upper end 3 with a thread 27 for fastening in, for example, a machine whereby the leveling unit can act as machine foot. The column 1 is at the lower end 6 passed through an opening 16 into the foot 5. The column 1 is attached to the foot 5 using a specially designed bottom nut 4, which is formed at the top 7 so that the surface is form complementary to the abutment surface 9, such as the bottom nut. 4 will act as its counterpart so that the upper surface 7 of the bottom nut 7 in the example shown is formed as part of a ball shell or spherical surface. The counterpart surface 9 of the bottom nut 4 is an inner side surface of the foot 5, which is also formed as part of a spherical surface.
    The ball shell surfaces or spherical surfaces on the upper end 7 of the bottom nut 4 and the counterpart 9 from the inner side of the foot 5 have the same radius and can therefore mutually exert contact with a large area which is suitable for transferring a large force.
    Thus, as will be apparent from the figures, it is part of the invention that:
    Leveling assembly comprises a column 1, which can be mounted at an upper end 3 to a workpiece such as a machine, and which is mounted at a lower end 6 in a foot 5, the leveling unit further being provided with a tightening device 2 comprising a top nut, which at clamping can lock the position of the column 1 with respect to the foot 5, where the lower end of the column 1 is inserted into the foot 5 and fastened to it by tightening a bottom nut 4, which at an upper end 7 is form complementary to the abutment surface 9 of the foot 5, which the bottom nut 4 will touch upon tightening.
    DK 2017 70114 A1
    It is a further feature of the invention that:
    • The upper end of the bottom nut 4 is partially spherical. By this it is to be understood that in the region of the through-hole of the bottom nut there is a surface which is spherical or spherical. The spherical surface is restricted upwardly by the through opening and below it is limited by the outer edge of the bottom nut. Both constraints are constituted by planes parallel to the same equatorial plane of the spherical plane. This common equatorial plane is perpendicular to the center axis of the thread of the bottom nut.
    • the bottom nut 4 is formed with a through-hole 17 and the threaded hole matches the outer thread on the lower portion of the column 1 so that the bottom nut 4 can be mounted thereon. • The bottom end 18 of the bottom nut 4 is flat as seen in Figures 2,3 and 4. The intersection between the bottom end 18 of the bottom nut and its outer sides may be more or less torn, and a facet may be provided here, such that the transition between the lower plane end of the bottom nut and the sides takes place via a surface having a tapered configuration. In one embodiment, the spherical upper face 7 extends all the way down to the tapered cut. This ensures that when the column 1 is tilted or tilted relative to the foot, the transition between the bottom plane end of the bottom nut and its sides will not encounter a bottom plate covering the foot downwards. In this case, as seen in the figures, the downwardly flattened surface of the bottom nut will be constituted by a limited anular region around the threaded hole of the bottom nut.
    GB 2017 70114 A1 • The height of the bottom nut 4 is minimized. This means that the bottom nut and its threaded handle with the column are designed to withstand a pull which does not exceed the maximum allowable pull in the column.
    • the bottom nut 4 is provided with tightening facilities 26 such as engagement holes, including for mounting the bottom nut and for fixing the same including using a pin screw 8. The bottom nut must be tightened while surrounded by the foot, and therefore there is limited space around it for e.g. engagement via a key that engages facets on any radially outwardly facing surface. Instead, two or more engagement holes 26 are provided at the lower end of the bottom nut. Hereby a key can be arranged with pins corresponding to the holes, so that the bottom nut can be tightened when the pins are inserted into the engagement holes. In one embodiment, the holes are disposed on the tapered piece. It is further necessary to secure the bottom nut against unintentional solution, which may occur due to strong vibrations in the machine parts carried by the column or in connection with earthquakes. For protection against accidental loosening, a through-hole is provided from the lower end up to the inner thread hole of the bottom nut, so that a pin-screw 8 as shown in FIG. 1,2 and 3. By tightening such a pin screw to the lower thread column, the bottom nut is secured thereto, and will only be loosened when the pin screw is again screwed outwards.
    • The leveling unit is provided with means including gaskets 19 suitable for use where there are high hygiene requirements. Gaskets 19 are provided at the transition between the column and the head nut 12 and between the vaulted piece and the head nut 12.
    DK 2017 70114 A1
    Finally, there will be gaskets 28 between all the heads of the screws or nuts which are passed down through the outward flange of the foot for attachment to the base and the top of the flange.
    The thread 10 around the lower end of the column matches the internal thread 11 of the bottom nut 4, as seen in the figures. The protruding flange of the top nut 12 has a downwardly facing abutment surface 14 and as shown, this surface fits a corresponding surface 15 on the central vaulted portion of the foot 20. The lower end 18 of the bottom nut 4 is formed with a flat surface which may be larger or smaller.
    The foot 5 itself, in extension of the arched portion 20, has a flange 21 which extends radially outwardly and has an upper side 22 and an underside 23, as well as an outer rim 24. Within the outer rim, the flange has through openings 25 and herein mounted fasteners which extend downwardly into the substrate and provide a bracket between the foot and the substrate. It is noted that the underside 21 of the flange in the central region below the column comprises a base plate and that the upper side thereof remains unaffected by the column tipping to the full extent where the column abuts the rim of the central hole 16 in the foot 5.
    By loosening the top nut 12, for example by engaging the tightening device 2, the column is released to be able to tilt. Thus, top nut 12 has a flange 13 projecting from the bottom of its inner thread 11, which has a bearing surface 14 as part of a ball shell formed for abutment with a corresponding outer surface, as part of a ball shell, bearing surface 15 on the upper side of the foot. about the opening 16 of the foot, the lower end 6 of the column being passed through this opening 16.
