  At the time of surveying, it is necessary to hold the surveying pole and the GPS surveying mobile station antenna pole at a surveying point in a highly accurate and stable vertical state. As described in Patent Document 1, as a holding device for these poles, a pole support arm is protruded from a main body provided on a leg head supported by a tripod, and the XY axis coordinate axis in the horizontal plane of the support arm is set. The support arm is set at a predetermined position by the movement based on the patent (Patent Document 1) or the movement based on the R-θ coordinate axis (Patent Document 2), and the pole is held vertically.

Japanese Patent Laid-Open No. 7-139948. JP 2001-227951 A.

  In the conventional means, a pole support arm protrudes laterally from the main part of the leg head supported by a tripod, and the tripod is purposely positioned at the side of the pole standing position. It is necessary to install. In such a case, the tripod should be installed with the reference amount. If the position shift is large, the adjustment amount of the pole support arm will increase, or if it is out of the adjustment range, the tripod installation position will be changed again. There is a need.

  Also, when carrying the instrument, it is convenient to fold the tripod part into a stick and it is compact and convenient, but the handling arm becomes inconvenient as the support arm protrudes, and the operability and accuracy of the instrument when the support arm is folded This causes problems.

  Accordingly, the present invention proposes a new holding device such as a surveying pole that supports the pole at the center position of the tripod.

  A holding device such as a survey pole according to the present invention has a rotating plate portion that is horizontally rotatable in a circular frame portion provided on a tripod support, and a rotating plate in a direction about the center diameter of the rotating plate portion. A rotation plate that forms a long hole that penetrates the portion and has a pole mounting portion that can mount a predetermined pole upright.

  Thus, a predetermined pole (a surveying pole or a GPS surveying mobile station antenna pole) is mounted on the pole mounting part, and a pole lower extension line (a lower end of the pole or a laser beam directed to an extension on the opposite side of the pole standing direction) ) Is matched to the object to be measured, and when the pole is not vertically upright, the tilt direction and angle are detected, and the rotation drive unit and linear drive unit are operated by a predetermined amount (moving the R-θ coordinate). Stand up vertically.

  Further, a holding device such as a surveying pole according to the present invention (Claim 2) includes a racking portion provided with teeth along the entire inner peripheral surface of the circular frame portion located below the rotating plate portion. The drive gear meshes with the rack ring portion, the drive motor disposed on the upper surface of the rotating plate portion, and the transmission portion that connects the drive gear and the drive motor.

  Thus, when the drive motor (first drive motor) is operated, the drive gear moves along the rack ring portion, and the rotary plate portion rotates (moves the θ coordinate of the upright position of the pole mounting portion). It will be.

  Further, the holding device such as a surveying pole according to the present invention (Claim 3) forms the inner edge of the long hole in the rail part, and forms the wheel of the vertical axis on the side edge of the moving plate part, The wheel is meshed with the part, and the moving plate part is mounted in the long hole.

  Thus, the moving plate portion moves linearly along the side edge of the long hole by the operation of the driving motor (second driving motor) fixed on the rotating plate portion (the R coordinate of the upright position of the pole mounting portion). Will move).

  Further, according to the present invention (Claim 4), the pole mounting portion is a cylindrical body vertically penetrating the moving plate portion, and a biaxial tilt sensor that crosses in the orthogonal direction on a horizontal plane is provided as an inclination angle sensor on the upper portion of the cylindrical body. It is used.

(X = 0, Y = 0) is converted into the R-θ coordinate system (conversion data is recorded in the control unit in advance), the rotational movement amount and the linear movement amount are determined, the first drive motor and the The operation amount of the two-drive motor is controlled.

  In addition, a holding device such as a surveying pole according to the present invention (Claim 5) has a lower base provided on a tripod support mounted with an upper base that is movable in a linear direction, and a little center of the upper base.

  The holding device such as a surveying pole according to the present invention is a moving plate portion that moves within a main body (circular frame portion: upper pedestal) provided on a tripod, instead of the support arm that projects the pole holding to the side of the main body. The pole is held by the pole mounting part provided on the tripod, and the tripod is placed directly above the surveying point (the center of the tripod), so that the tripod can be installed quickly and reliably. Setting up standing (vertical standing up) will be performed quickly, which contributes to improving the efficiency of surveying work.
