Description

  The present invention relates to an apparatus for positioning a surveying instrument when the surveying instrument is installed.

  The surveying instrument is installed by mounting the surveying instrument horizontally on a tripod that has been set up in advance, and then using a centripetal device such as a centripetal telescope or laser centripetal device to position the surveying instrument directly above the surveying point. It is done by adjusting so that.

  Conventionally, in order to align the surveying instrument to the centripetal position indicated by the centripetal apparatus, it has been performed only by the centripetal position adjusting device built in the surveying instrument. However, when alignment is performed only with the centripetal position adjustment device, there is a limit to the adjustment range, so alignment may not be possible unless the tripod is re-installed, and work efficiency during installation is not good. There was no problem.

  In order to solve such a problem, in Patent Document 1, a tripod base to which a surveying instrument is attached is adjusted to a reference point adjustment plate that can be moved in a horizontal direction by a horizontal movement adjustment unit, and a horizontal angle is adjusted by a horizontal angle adjustment unit. Proposed annular pedestals. Here, the horizontal movement adjusting means is configured to adjust the horizontal position of the surveying instrument by means of three screws provided so as to be in contact with the circumferential surface of the disk forming the reference point adjusting plate.

According to the technique described in Patent Document 1, the horizontal movement adjusting means and the horizontal angle adjusting means provided on the tripod are compared with the case where the positioning of the surveying instrument is performed only by the centripetal position adjusting device built in the surveying instrument. Because the adjustment range of surveying instruments is widened, the work of re-installing a tripod during installation can be reduced.
JP-A-9-257482

  However, in the above-described tripod described in Patent Document 1, the tripod includes a reference point adjustment plate that can be moved in the horizontal direction by the horizontal movement adjustment means of the surveying instrument, and an annular pedestal that can adjust the horizontal angle by the horizontal angle adjustment means. Since the weight and size of the tripod itself increases and the work efficiency when installing the tripod is not good, the work efficiency and installation accuracy when installing surveying equipment are still improved. There was room for improvement.

  In addition, the tripod described in Patent Document 1 described above is configured to adjust the horizontal movement of the surveying instrument with screws that are in contact with three locations on the circumferential surface of the reference point adjustment plate. There was also a problem that it was complicated and it was difficult to perform alignment accurately.

  Therefore, the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a positioning device for a surveying instrument that can perform the installation work of the surveying instrument with high accuracy and efficiency.

  In order to solve such a problem, the positioning device for a surveying instrument according to the present invention includes a second part having a connection part with a tripod on the upper surface of the first member having a connection part with a tripod on the lower surface. The members are engaged so as to be horizontally movable, and one of the first member and the second member is configured to move horizontally relative to the other.

  According to this configuration, since the positioning of the surveying instrument can be performed by horizontally moving one of the first member and the second member relative to the other, the positioning of the surveying instrument can be performed with high accuracy and It can be done efficiently.

  Moreover, since the positioning device of the surveying instrument is provided separately from the tripod and the surveying instrument, the tripod itself can be reduced in size and weight compared to the technique described in Patent Document 1 described above. The positioning of the surveying instrument can be performed with high accuracy and efficiency without impairing the work efficiency when the tripod is installed.

  Furthermore, by providing a surveying device alignment device separately from the tripod and surveying device, this surveying device alignment device can be connected to an existing tripod or surveying device to align the surveying device. Since it can be performed, excellent versatility can be obtained and the apparatus cost can be reduced.

  The positioning device for a surveying instrument according to the present invention may be configured such that at least one of the first member and the second member is provided with a movement guide means that enables the horizontal movement. Here, the movement guide means is not particularly limited, and for example, a cross roller guide, a linear ball, or a ball screw can be used. According to this configuration, the relative horizontal movement of the first member and the second member can be performed with higher accuracy and efficiency.

  Moreover, in the positioning apparatus for surveying instruments which concerns on this invention, it is good also as a structure which provided the said connection part detachably with respect to said 1st member and said 2nd member. According to this structure, since the connection part from which a dimension and a shape differ suitably according to various surveying instruments and a tripod can be used, the outstanding versatility is acquired.

  According to the positioning device for a surveying instrument according to the present invention, the surveying instrument can be installed with high accuracy and efficiency.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
