Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pole holder for holding a surveying pole used in surveying work.

(Prior Art) Conventionally, in surveying work performed using a surveying telescope and a surveying pole, the surveying pole was supported by the worker himself at the survey point.

(Problems to be Solved by the Invention) In the above-mentioned conventional method, the worker himself had to support the surveying pole, and a worker was needed to operate the telescope.

(Means for Solving the Problems) In order to solve the above problems, the present invention includes a base that is detachable from the leg head of a surveying tripod, and a base that extends horizontally to the base and that rotates around the axis. It consists of a supporting member that is rotatably and horizontally movable, and a pole holder that is tiltably supported at one end of this supporting member and has a holding part that holds a surveying pole. be.

(Function) The base of the surveying pole holding device is attached to the leg head of the surveying tripod, and the surveying pole is held in an upright state on the holding part of the pole holder, and the support arm is attached to the base.
The surveying pole is held perpendicular to the survey point by horizontal movement, rotation around the axis, and tilting of the pole holder relative to the support arm.

(Example) Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes the base of the pole holding device, which consists of a cylindrical main body 1a and a flange 1b protruding from the bottom of the main body 1a.
b can be mounted on the installation surface by attaching it to the leg head of an existing surveying tripod S, and a circular space is formed in the center of the bottom surface, and the pedestal 2 is mounted within the space. A nut part 3 is formed in the center of this pedestal 2, into which a mounting bolt B provided approximately in the center of the leg head is screwed, and a nut part 3 is formed on the top surface of the pedestal 2 on both sides of the nut part 3. A receiving portion 4 having a U-shaped recess is integrally formed in a protruding manner. A substantially rectangular space communicating with the space is formed in the main body 1a, and a substantially rectangular fixing member 5 is loosely inserted into this space, and a mounting ring 6 is provided on the top of the fixing member 5. The receiving part 4 is formed in the lower part.
A presser portion 7 is formed having a U-shaped recessed portion facing the. A fixing bolt 8 is screwed into the upper end of the main body 1a of the base 1.
The lower end of the fixing member 5 is loosely fitted into the mounting ring 6 of the fixing member 5, and the fixing member 5 is fitted with a set screw 9 from below.
It is mounted rotatably relative to the By screwing in and retracting the fixing bolt 8, the fixing member 5 is moved up and down using the wall of the space as a guide. Note that an operation camera 8a is attached to the upper end of the fixing bolt 8. In addition, through-holes 10, 10 are provided through the outer periphery of the main body 1a of the base 1, and these through-holes 10, 10 are connected to the U of the receiving part 4 and the holding part 7.
It is located on the same line as the central axis of the shaped recess.

The support member 11 consists of a long support rod 12 and a tilting arm 14 connected to one end (the left end in the figure) of the support rod 12 by a support pin 13.
This support rod 12 is inserted into the insertion hole 1 of the base 1.
0 and 10, and is supported by a receiving portion 4 within the base 1 to enable movement in the horizontal direction and rotation around its axis, and an operation camera 12a is attached to the other end. In addition, tilting arm 1
A pole holder 15, which will be described later, is supported at one end (the left end in the figure) of the arm 4 via a support pin 16 and a bifurcated bracket 17 so as to be tiltable in the same direction as the tilting direction of the tilting arm 14.

The pole holder 15 has a holding portion 1 having a V-shaped flat section.
A pair of clamping pieces 16a and 16b made of plate springs are formed on the front surface of the pole P in the upper and lower directions, and approximately at the upper and lower parts thereof, the clamping pieces 16a and 16b are made of plate springs that elastically clamp and hold the surveying pole P.
A bubble-type spirit level 18 is attached to the upper end surface of the pole holder 15.

This embodiment is configured as described above,
Next, its effect will be explained.

First, the entire pole holding device is placed on the leg head of an existing surveying tripod S, and the base 1 is mounted on the leg head, and the mounting bolt B of the surveying tripod S is attached to the base 1 side. Screw it into the nut part 3 and tighten it. Then, the surveying pole P is erected on the V-shaped holding portion 15a of the pole holder 15 extending from the base 1 via the support member 10, and is elastically supported by the elasticity of the pair of clamping pieces 16a and 16b. Clamp and fix (hold).

Therefore, the surveying pole P is adjusted so that it stands perpendicular to the survey point, and the base 1
After setting the support rod 12 of the support member 11 in a free state, the lower end of the surveying pole P held by the pole halter 15 is placed above the ground in order to position it at the survey point. When the support rod 12 is in contact with the base 1
while moving the support rod 1 in the horizontal direction.
By tilting the tilting arm 14 with respect to 2 and further tilting the pole holder 15 in the same direction with respect to the tilting arm 14, for example, the tilt in the front-back direction is adjusted, and by rotating the support rod 12 around its axis. , adjust the inclination in the left-right direction perpendicular to the front-back direction. Adjustment of the inclination in each direction is performed while observing the level 18 attached to the pole holder 15. After this adjustment, when the fixing bolt 8 is rotated in the direction of screwing into the main body 1a of the base 1, the inclination is adjusted in each direction. As the fixing member 5 is moved downward as the fixing bolt 15 is screwed in and rotated,
The support rod 12 is fixed to the base 1 by the presser portion 7 of the fixing member 5 and the receiving portion 4 of the pedestal 2 opposing it. In this way, the surveying pole P is held vertically to the survey point.

(Effects of the invention) According to the invention, the entire pole holding device can be attached to an existing surveying tripod as is, and the surveying pole can be securely held by the pole holder of the pole holding device, unlike the conventional method. This eliminates the need for the worker to support the pole himself, making it possible to streamline this type of surveying work. Furthermore, since the support member can be moved and tilted in the horizontal direction relative to the base, the surveying pole held by the pole holder can be moved easily to the survey point by rotating around its axis and tilting the pole holder. It can be installed vertically.
