    Reading device for transport protection of leveling device with integrated weighing cell
    BACKGROUND OF THE INVENTION The invention relates to a laser device for transporting a leveling unit with an integrated weighing cell, which leveling type is comprised of a spindle for fastening in an assembly such as a machine, which spindle is connected to a base arranged for contact with a foundation such as a base. floor, the lower part comprising a housing in which a weighing cell with an actuating surface is located, as well as a power transfer assembly passing through the upper side of the lower part and extending the connection between the lower part and the spindle, which power transfer assembly comprises a lower end surface adapted to form abutments with the weighing cell's activating surface and an upper end surface arranged to engage the lower end surface of the spindle,
    From DK Patent No. 177805 B1, leveling assemblies of the above type are known with integrated weighing cell, but without transport.
    The purpose of this invention is to provide a transport safety device, among other things, for this type of leveling assembly.
    The form of the invention is met by a leveling assembly such as that set forth in the preamble of claim 1, further characterized by an orbiter which encloses the lower end of the spindle and is screwed to an external thread on this part and is thereby inserted between this lower part and the upper side. of the lower part
    In this way, it will thus be possible to protect a leveling unit with integrated weighing cell by unscrewing the encoder (2) with respect to the spindle (1) by means of suitable tools, so that the encoder (2) is pressed against the upper side (8) of the lower part ( 4) hereby obtaining that the downward-facing end face of the bolt (3) is pulled away, and thereby out of abutment, with the upwardly activating surface of the weighing cell (5) (Fig. 5.5) in (9) and at the same time the parts of the leveling assembly become spindle (1). ) and sub-section (4), read together until the transport reading is deactivated.
    As stated in claim 2, in that the PTO fixed engagement with the lower end surface of the spindle is a threaded assembly loaded with thread glue. hereby the advantage is obtained that the adjustment of the weighing cell is not disturbed by the use of the transport reading.
    The invention will now be explained in more detail with reference to the drawings, in which:
    FIG. 1 shows a leveling unit with integrated weighing cell
    FIG. 2 shows the same leveling unit with integrated weighing cell seen at a slightly different angle while
    FIG. 3 shows the same leveling assembly seen directly from one side, while FIG. 4 shows the leveling assembly cut through in plan A-A; FIG. 3, while FIG. 5 shows the deactivated laser device seen as an enlarged detail shown in circle C; FIG. 4, mens
    FIG. 6 shows the leveling assembly seen directly from above, whereas
    FIG. 7 shows the leveling assembly cut through in plane B-B; FIG. 6, mens
    FIG. 8 shows the active reading device seen as an enlarged detail shown in circle D; FIG. 7th
    FIG. 9.Show the starting point. In fig. 1 and 2 there is shown a leveling assembly of the type consisting of an upper part comprising a spindle (1) with a thread of the upper part thereof, intended for screwing into a supported assembly such as a machine or machine part, this thread being in addition, partially enclosed by a combined thread cover (13) and welding torque for shielding the portion of the thread not screwed into the supported assembly and for securing the spindle to the same assembly, and a cylindrical, two-piece, smoothly screwed lower portion below this thread ( 1) and (Figs. 5, 2), each of which is provided with oppositely located faces (11 and 12) of limited extent for receiving tools such as fork nails for independent manipulation of the spindle parts.
    This spindle is, via a power transmission assembly (3) which e.g. as in the example shown, may be designed as a bolt (3) with a bolt head formed on its underside to fit with the underside (8a) of the lower part (4), which lower part (4) is intended for contact with a underlying foundation such as a floor and is therefore provided with a pair of bores (14) for receiving through-going screws for any attachment of the base (4) to this underlying foundation. The lower part of the embodiment shown here is arranged with a cavity precisely adapted to receive a weighing cell (5) with an upwardly activating surface (Figs. 5, 5) adapted to form abutment surface (9) against the downwardly convex end surface of the power transmission assembly (3) also called the bolt (3).
    FIG. 5 shows an enlarged section of the circle C of FIG. 4. This section shows the loading device for transport protection of the leveling unit with the transport reading deactivated as soon as the unit is in weighing mode.
    FIG. 7 is an enlarged section of the circle D of FIG. 7. This section shows the transport protection reading device with the transport reading activated so that the unit is in transport mode.
    It can be seen from FIG. 5 and FIG. 7 that the spindle (1) is rotated downwards to a diameter smaller than the diameter of the other spindle (1). This pivot is provided with an external thread on which is screwed an orbiter (2), the same lowered part of the spindle (1) further comprising a center hole in which there is an internal thread (10) for receiving the thread portion of the bolt (3) .
    The assembly of spindle (1) and lower part (4) occurs by screwing the bolt (3) from the inside of the lower part (4) through its upper side through a hole that is oversized in relation to the diameter of the bolt (3) but smaller than the head of the the same bolt (3) and further through a center hole in the perimeter (2) and thence into the center hole of the downwardly extending portion of the spindle (1) where the length of the screw-in of the bolt (3) is adjusted so that there is contact (9) between the weighing cell (5) upwardly actuating surface (Figs. 5, 5) and the downward-facing end face of the bolt (3) (the convex head of the bolt), after which the bolt (3) is fixed to the thread (10). with thread glue like Loctite.
    The orbiter (2) is provided with substantially static O-ring seals (6) which, however, must also be able to withstand limited dynamic movements, both to the spindle (1) side and to the lower part (4), to ensure optimum tightness between these machine parts. and so that no dirt and bacteria enter and also so that the surfaces of these collections are relatively easy to clean.
    The transport protection from weighing mode is activated by unscrewing the nut (2) relative to the spindle (1) by means of suitable tools, such that the nut is pressed against the upper side (8) of the lower part (4) and the bolt head is pressed against the inner side of the upper part. (8a) of the lower part (4) thereby obtaining that the downwardly convex end face of the bolt (3) is pulled away from the upwardly activating surface of the weighing cell (5) (Figs. 5, 5) in (9) and at the same time the leveling assembly becomes parts, spindle (1). ) and sub-section (4), read together until the transport reading is deactivated.
    The actuation is carried out by screwing the inverter again in relation to the spindle (1).
    Here, the laser device for transport protection of leveling unit with integrated weighing cell is explained on the basis of a leveling unit similar to that described in DK Patent No. 177805 B1, but can in principle be used for transport protection in many other contexts with similar joints.
