Note that the bottom plate 38 and the base upper plate 40 may not have a ring shape.

  In the present embodiment, there are three support columns 42 that connect the bottom plate 38 and the base upper plate 40, and are arranged at three locations. Specifically, each column 42 is provided at an intermediate position between adjacent magnets 44 in the three magnets 44. That is, when viewed from the center of the circle of the bottom plate 38, the columns 42 are arranged with an interval of 120 ° from each other. As described above, the positions of the plurality of magnets 44 and the positions of the plurality of support columns 42 are in the middle positions of each other, so that the weight balance of the base 31 is extremely stable.

Next, the structure of the mounting portion 32 will be described.
The mounting portion 32 includes a mounting top plate 46 and a bottom plate 48 disposed below the mounting top plate 46 at a predetermined interval. The mounting top plate 46 and the bottom plate 48 are connected by a plurality of columns 50. The mounting upper plate 46 is formed in a ring shape with an opening 47 formed in the center. A GNSS receiver is mounted in the opening 47. The bottom plate 48 is a circular flat plate, and the bottom surface of the GNSS receiver is in contact with the bottom plate 48.
In addition, the support | pillar 50 is provided so that it may extend vertically downward from the lower surface of the mounting | wearing upper board 46, and the vertical member said in a claim corresponds to the support | pillar 50 of this embodiment.

Next, the horizontal vibration absorbing member will be described.
As the horizontal vibration absorbing member, a coil spring 36 is employed in the present embodiment. The coil spring 36 is disposed so that the expansion and contraction direction is horizontal, one end of which is attached to the support 50 and the other end is attached to the upper surface of the base upper plate 40 of the base part 31.
Moreover, although the coil spring 36 in this embodiment is provided in three places at equal intervals mutually, the installation location of the coil spring 36 is not limited to three places.

  The vertical vibration absorbing member is not limited to a coil spring, and for example, rubber or the like can be employed.

As described above, the mounting portion 32 to which the GNSS receiver is mounted is absorbed by the base rope 31 in the vertical direction by the wire rope vibration isolator 34 and by the coil spring 36 in the horizontal direction. Therefore, it is possible to prevent vibration from construction equipment from being applied to the GNSS receiver.
In the present embodiment, the three wire rope anti-vibration devices 34 are arranged at intervals of 120 ° with respect to the center of the circle of the mounting portion 32 in plan view. Similarly, the three coil springs 36 are planar. They are arranged at an interval of 120 ° with respect to the center of the circle of the mounting portion 32 as viewed. For this reason, it is possible to solve a so-called parallel shift problem in which vibration cannot be absorbed in a predetermined direction.

Next, a method for mounting the GNSS receiver in the mounting unit 32 will be described.
When the GNSS receiver to be mounted is circular in plan view, the diameter of the opening of the mounting upper plate 46 of the mounting portion 32 is formed to be slightly smaller than that of the GNSS receiver, so that the main body portion of the GNSS receiver is formed. It is arranged inside the mounting upper plate 46 of the mounting part 32. Further, the flange portion formed at the upper end portion of the GNSS receiver is placed on the upper surface of the mounting upper plate 46.

Furthermore, it is preferable to provide a detent for preventing the GNSS receiver from rotating in the circumferential direction at a predetermined position on the mounting upper plate 46. In the present embodiment, as an example of the rotation stopper, a cut portion 49 cut toward the inner opening is provided. The shape and size of the cut portion 49 may be appropriately changed according to the shape of the GNSS receiver to be mounted.
In addition, as an example of the rotation stopper, a protrusion protruding upward may be used instead of a recess recessed like a cut portion. Furthermore, as another example of the rotation stopper, a cover that covers the entire GNSS receiver may be provided, and the cover may be fixed to the mounting portion 32.

Further, the length of the support column 50 may be set so that the bottom surface of the GNSS receiver to be mounted comes into contact with the bottom plate 48 of the mounting portion 32. By setting in this way, the GNSS receiver is stably mounted.
Further, the bottom plate 48 of the mounting portion 32 may be provided with a screw 51 for screwing the GNSS receiver when a screw hole for attachment is formed on the bottom surface of the GNSS receiver. The lower end portion of the screw 51 is provided with a gripping portion 52 that is formed with irregularities on the surface so that the worker can easily turn the screw and is easy for the worker to grip.

  However, the place where the screw 51 is provided varies depending on the type of the GNSS receiver, and therefore, it may be appropriately adjusted to the structure of the screw hole on the bottom surface of the GNSS receiver.

Further, an antenna hole 56 through which an antenna (not shown) extending downward from the GNSS receiver may be formed in the bottom plate 48 of the mounting portion 32.
If comprised in this way, an antenna will protrude below from the baseplate 48 of the mounting part 32. FIG. At this time, since the antenna is disposed inside the base portion 31, the antenna can be protected by such a configuration.
