Description

  The present invention relates to a positioning auxiliary device (ruler) for three-dimensional measurement used for positioning (marking) using a three-dimensional measuring instrument (total station) and a positioning method using this device.

  For example, when installing a steel beam member (steel material such as a beam) at a predetermined position on a support material that supports the steel beam member, the installation position is marked on the support material in advance (so-called ink marking), and this mark (marking) ) As a mark, it is necessary to install a steel material (beam etc.) on the support material.

  As an example, when building a roof or the like in a wide space with few pillars, it is necessary to connect a plurality of beam members of a predetermined length and span a long span (between side walls) to form a beam. In such a case, support members as temporary placement stands (installation support stands) for the beam members are arranged at a predetermined interval obtained by dividing a long span into several parts, and precisely at the top end (upper surface) of those support members. It is necessary to mark the positioned mark and install the beam member according to the mark. In other words, if the position of the mark is not accurate, the error will increase if the span is long. For example, if the beam members are joined from both ends and connected at the center, the error prevents the center connection. There is a fear.

  Therefore, conventionally, a pin pole prism as described in Patent Document 1 or Patent Document 2 (a rod-shaped pole is connected to a pin with a sharp tip, and a reflection prism for measurement is connected to the pole) The attached prism is placed upright on the top of the support with the pin side down (see Fig. 14 (A)), and in that state the reflecting prism is moved with a three-dimensional measuring instrument. It was collimated and measured (coordinates were obtained) (see FIG. 14B).

  Then, the operator calculates the difference between the obtained coordinates (the position of the reflecting prism) and the target position (target coordinates: the position to be marked), moves the pin pole prism according to the difference, and moves The target position (target coordinates) to be obtained is obtained by repeating the operation (procedure) such that the reflecting prism is collimated again with a three-dimensional measuring instrument at a later position and measured (obtains coordinates) several times. I was doing complicated and time-consuming work.

  In addition, when performing inking (when drawing a straight line to be along one end of the beam), it is necessary to obtain the target coordinates described above and then follow the same procedure to obtain another target coordinate. It is possible to draw a straight line only after obtaining these two points, and further complicated and time-consuming work is required. In addition, when it is desired to mark a certain point on the line, it is necessary to obtain the target position (target coordinates) to be obtained again by the same procedure as described above, and further complicated and laborious work is required. It was.

  A three-dimensional measuring device is a measuring device that measures the distance and angle to a measurement target using light waves, lasers, etc., and is oscillated from the three-dimensional measurement device and reflected by a reflecting prism attached to the measurement target. By detecting light waves (or lasers, etc.) with a three-dimensional measuring device, it is possible to measure the reflecting prism, that is, the distance to the measurement object, the horizontal angle, the vertical angle, etc., and based on these, the three-dimensional measuring device With respect to a measurement coordinate system (surveying coordinate system) centered on the three-dimensional coordinates of the measurement target can be acquired.

JP 2001-33250 A Japanese Patent Laid-Open No. 2002-22443

  Here, in order to perform measurement (surveying) with high accuracy, it is important to hold the pin pole prism horizontally or vertically, but the pin pole prism is supported by the operator or supported by a dedicated tripod. However, it is inefficient because it is an unstable tool, and it is inefficient to hold the pin pole prism at the top of the support material at a high place or support it with a dedicated tripod. Work.

  As described above, the work until obtaining the required coordinate position is to move the reflecting prism (pin pole prism) closer to the target while observing the difference between the value obtained by measurement and the target (point). It is difficult to maintain horizontal holding (vertical holding) every time the reflecting prism is moved, due to the influence of the working environment of working at a high altitude. Repeated measurement reaches the target coordinate position. Until then, it becomes a troublesome task of repeatedly going back and forth with the reflecting prism back and forth or left and right.

  In addition, since only one point of coordinates can be obtained with one reflecting prism in the first place, two points of coordinates are necessary to draw a reference line on which the steel material is placed. Work is required at least twice.

  By the way, also in such a method using the conventional reflecting prism, the time until the reflecting prism reaches the target can be shortened to some extent by the skill of the operator. However, the actual situation is that engineers and managers taking care of the site do not want to spend much time and effort on the basic measurement (surveying) work of positioning the steel frame.

  The present invention has been made in view of such circumstances, and when acquiring the target coordinate position by measuring the coordinate position of the reflecting prism with a three-dimensional measuring device, it is simple and low cost, easily and quickly, It is an object of the present invention to provide a positioning auxiliary device for three-dimensional measurement that can contribute to obtaining a target coordinate position with high accuracy (positioning) and a positioning method using this device.

For this reason, the positioning assist device for three-dimensional measurement according to the present invention is

In the present invention, a fixing device capable of switching a state where the slider of the slide guide is fixed or not fixed to the slide guide;
It is possible to provide a lock device capable of switching a state where the rotation of the rotation arm is fixed or not fixed.

  In the present invention described above, the lower end side of the side surface of the rotary arm is substantially coincident with a straight line connecting the center of the rod-shaped member supported by the first support means and the center of the rod-shaped member supported by the second support means. It can be characterized by being formed in a concave shape.

  In the present invention, a scale corresponding to the distance from the center of the rod-like member supported by the first support means or the second support means is provided near the lower end of the side surface of the rotary arm along the long axis direction of the rotary arm. It can be characterized by being provided.

In addition, the positioning method according to the present invention includes:
A positioning method using the three-dimensional measurement positioning auxiliary device according to the present invention,
The position of the reflecting prism supported by the slider via the first support means is measured by the three-dimensional measuring device, and the position of the reflecting prism is set to the target coordinate position in the depth direction with respect to the three-dimensional measuring device. Moving the slider along,
While maintaining the slider at that position, the position of the reflecting prism supported by the rotary arm via the second support means is measured by a three-dimensional measuring device, and the position of the reflecting prism becomes the target coordinate position in the depth direction. Rotating the rotating arm around the rotation axis with respect to the slider;
Including
By drawing a line along the rotating arm in this state, the target coordinate position in the depth direction related to the three-dimensional measuring device is passed, and a straight line parallel to the left-right direction related to the three-dimensional measuring device is obtained.
Based on this straight line and the difference between the target coordinate position and the coordinate position in the left-right direction of the reflecting prism supported by the rotary arm at the target coordinate position in the depth direction, the target in the depth direction and the left-right direction It is characterized by obtaining the coordinate position.

  According to the present invention, when acquiring the target coordinate position by measuring the coordinate position of the reflecting prism with a three-dimensional measuring device, the target coordinate position is easily and quickly acquired with high accuracy while being simple and low-cost. It is possible to provide a positioning auxiliary device for three-dimensional measurement that can contribute to performing (positioning) and a positioning method using this device.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments described below.

  As shown in FIG. 1, a three-dimensional measurement positioning auxiliary device 100 according to an embodiment of the present invention includes a linear slide guide rail 30 as a slide guide, and a bearing or the like along the slide guide rail 30. And a slider 40 guided so as to be slidable (movable).

For example, as shown in FIG. 1, FIG. 2, etc., the guide rail 30 is configured by a rail having a C-shaped cross section orthogonal to the longitudinal direction, and the opening of the C-shaped cross section is positioned above. It is arranged.
A block-shaped slider 40 having a cross section corresponding to the C-shaped cross section of the guide rail 30 and having a predetermined gap with the C-shaped cross section of the guide rail 30 is slidable. It is inserted from the part. In addition, after inserting, it can be set as the structure which attaches a stopper etc. so that the slider 40 may not drop from the guide rail 30. FIG.

  Even if the entire apparatus is turned upside down, the slider 40 is regulated by the shoulder of the opening of the C-shaped cross section, so that it does not detach from the guide rail 30 (disengage upward in FIGS. 1 and 2). It is configured as follows. However, other guide groove shapes can be used.

  The slider 40 can rotate in the clockwise direction and the counterclockwise direction around the rotation axis 40A with respect to the slider 40 on the plane of the upper end of the support member on which the slider 40 slides along the slide guide rail 30. A substantially linear rotating arm 50 (which can swing or pivot) is attached (supported).

  The lower surface of the slide guide rail 30 and the lower surface of the rotary arm 50 are set to have substantially the same height. That is, the rotary arm 50 is configured to rotate around the rotation axis 40A along the plane on which the slide guide rail 30 is placed.

The rotary arm 50 can be rotated around the rotary shaft 40A, but can be fixed so that rotation around the rotary shaft 40A (rotation with respect to the slider 40 does not rotate) by manually operating the lock lever 42 by the operator. It is configured as follows.
Such a lock lever 42 corresponds to an example of a lock device according to the present invention.

As an example of the lock lever 42, a configuration as shown in FIG. 13 can be adopted.
As shown in FIG. 13, the rotary arm 50 is rotatably supported around a rotary shaft 40 </ b> A (screw portion 43) integral with the slider 40. ) 42A. The wheel 42A is slidably fitted on the outer periphery of the rotating shaft 40A (screw portion 43), and a slit (notch) 42B is provided in a part of the circumferential direction. A shaft integral with the lock lever 42 is rotatably inserted so as to span the slit 42B, and a screw portion provided on the outer periphery of the front end side of the shaft faces the slit (notch) 42B. It is screwed into only one of the loops 42A.

  For this reason, when the lock lever 42 is turned in one direction, one of the rings 42 is attracted to the other by the action of the screw part, and the gap between the slits 42B is narrowed to act to tighten the outer periphery of the rotary shaft 40A (screw part 43). As a result, the rotation of the rotary arm 50 around the rotary shaft 40A is fixed. Further, when the lock lever 42 is turned in the opposite direction, one of the wheels 42 is separated from the other by the action of the screw portion, and the interval of the slit 42B is widened so that the outer periphery of the rotating shaft 40A (screw portion 43) is not tightened. Therefore, the rotation of the rotary arm 50 around the rotation axis 40A can be permitted (the rotation is not fixed).

  However, the present invention is not limited to this. When the lever is operated in the fixing direction, the cam is pressed against the shaft portion of the rotating shaft 40A to stop the rotation, and when the lever is operated in the releasing direction, the cam is separated from the shaft portion of the rotating shaft 40A. Thus, a commercially available mechanism that can be rotated can be used.

  In the three-dimensional measurement positioning auxiliary device 100 according to the present embodiment, for example, the pole 10 is coaxially connected to the rotary shaft 40A of the slider 40 by the first support means of the screw portion 43 (or insertion or the like). It is configured to be able to stand (configured to be able to stand substantially perpendicular to the rotation plane (substantially horizontal plane) of the rotary arm 50), and the reflection prism 1 is attached to the pole 10 at the mounting angle and mounting height. Etc. can be adjusted (the angular position can be adjusted for measurement by a three-dimensional measuring device). The pole 10 is a cylindrical rod-shaped member made of metal, resin, or other material.

The pole 10 and the reflecting prism 1 can be attached substantially integrally with the slider 40 (rotating shaft 40A), but are attached independently from the rotating operation of the rotating arm 50.
However, since the pole 10 and the reflecting prism 1 have already been measured, it is possible to make them rigid so as to rotate integrally with the rotating operation of the rotating arm 50.

  Further, near the tip of the rotary arm 50 (the other end when the rotation shaft 40A side (rotation center side) is the base end side, the end portion away from the rotation shaft 40A), for example, the screw portion 51 (or insertion) Etc.) so that the pole 20 can be erected substantially vertically (for example, can be erected substantially perpendicular to the rotation plane (for example, substantially horizontal plane) of the rotary arm 50). The reflection prism 2 is attached to the pole 20 so that the attachment angle, the attachment height, etc. can be adjusted (the angle position can be adjusted for measurement by a three-dimensional measuring device) The pole 20 is made of metal, resin, etc. It is a cylindrical rod-shaped member made of the above material.

  Further, as the reflecting prism 1 and the pole 10 and the reflecting prism 2 and the pole 20 according to the present embodiment, those obtained by removing a pin (detachable screwing method) at the tip of a commercially available pin pole prism can be used as they are.

  Furthermore, a graduation (in the vicinity of the lower end of the side surface of the rotary arm 50 (for example, the side where the three-dimensional measuring device is installed) (near the surface on which the slide guide rail 30 is placed) along the major axis direction of the rotary arm 50 ( (Major, straight ruler) 52 is disposed.

  It should be noted that the operator does not interfere with the measurement by the three-dimensional measuring device (so as not to enter between the three-dimensional measuring device and the reflecting prism 1 or 2). Since the operator is at the back of the reflecting prism 1 and 2, when looking at the scale 52, the operator looks into the scale 52 from above. They are arranged upside down (the lower side in FIG. 1 is the upper side of the characters).

  Further, the lower end side of the side surface of the rotary arm 50 to which the scale 52 is attached (pasted) is curled inward (the concave portion 53 is formed in a concave shape) as shown in FIG. The position of the scale 52 (position in the short axis direction of the rotary arm 50) is substantially coincident with a straight line connecting the center of the pole 10 (reflecting prism 1) and the center of the pole 20 (reflecting prism 2). Therefore, when a line is drawn along the scale 52, a line is drawn on a straight line connecting the center of the pole 10 (reflecting prism 1) and the center of the pole 20 (reflecting prism 2).

  Further, the position of the scale 52 is adjusted so that the position indicated by the scale 52 coincides with the difference from the reflecting prism 2. That is, the difference from the reflecting prism 2 can be read on the scale 52 and the target position can be marked.

  The material of the slide guide rail 30, the slider 40, the rotary arm 50, etc. is not particularly limited, but can be made of metal such as aluminum, titanium, stainless steel, or resin such as plastic. It is also possible.

  In addition, when the 3D measurement positioning auxiliary device 100 according to the present embodiment is used on a steel frame or the like, the slide guide rail 30 and the back surface (lower surface) of the rotary arm 50 are arranged on the back surface of FIG. As shown, by attaching the magnet 54 and the like, it is possible to suppress inadvertent movement, overturning or falling.

  Using the three-dimensional measurement positioning auxiliary device 100 according to the present embodiment having the above-described configuration, the worker performs positioning in the following procedure (step) (FIGS. 5 to 5). 7).

Prior to the measurement, a three-dimensional measuring device is installed at a position where the installation position of the steel material can be seen. The three-dimensional measuring device collimates the reflecting prisms installed at two known points, measures the distance and angle between the three-dimensional measuring device and the two points, and determines the position of the three-dimensional measuring device. Calculate the coordinates.
In order to install the steel material at a predetermined position on the support material that supports the steel material, it is necessary to mark the support material on the support material in advance and install the steel material on the support material using this mark as a mark. However, the three-dimensional measurement positioning auxiliary device 100 according to the present embodiment is used when the installation position is marked on the support material in advance.

First, before positioning, for example, it is necessary to mark a beam member to be installed at a target position on the top end of the support material.
In a scene where the beam member is installed at the top end of the support member, the member is marked for alignment with the support member before the member is lifted by a crane or the like.

  In step 1 (procedure 1), the three-dimensional measurement positioning auxiliary device 100 according to the present embodiment is placed on the support member, and the three-dimensional coordinate value (current position) of the reflecting prism 1 is measured by the three-dimensional measurement device ( (Refer to Procedure 1, FIG. 8, FIG. 9 and FIG. 9A in FIG. 5).

  Here, when placing the three-dimensional measurement positioning auxiliary device 100 according to the present embodiment on the support member, the slider 40 is in a free state (movable state) with respect to the slide guide rail 30, for example. The depth direction of the measurement by the three-dimensional measurement device (the X-axis direction of the survey coordinate system in FIGS. 5 to 7, the depth direction with respect to the three-dimensional measurement device) so as to be located at an arbitrary position in the longitudinal direction of the slide guide rail 30 ) And the long axis direction of the slide guide rail 30 are set so as to be substantially coincident (not strictly) (fixed to some extent by a magnet or the like so as not to be misaligned during operation) (see FIG. 9A as an example). ).

  Note that it is only necessary that the coordinate value in the depth direction of the reflecting prism 1 can be changed by moving the slider 40 and the reflecting prism 1 along the slide guide rail 30 (the slider 40 and the reflecting prism 1 can be changed). Since it is sufficient if the depth direction component of the coordinates can be changed when moved along the slide guide rail 30), the long axis direction of the slide guide rail 30 is in the depth direction (X-axis direction of the survey coordinate system). On the other hand, it may be diagonal.

  In addition, the rotary arm 50 is set to a position that is substantially orthogonal (not strictly) to the slide guide rail 30, for example, as a free state (a rotatable state) with respect to the slider 40. However, it can be set at another position.

  In step 2 (procedure 2), the difference between the measured value in the depth direction (X-axis direction of the survey coordinate system) and the target position (the coordinate value of the target position, the target coordinate value) is calculated (obtained), The slider 40 and then the reflecting prism 1 are moved on the slide guide rail 30 by the difference (see procedure 2 in FIG. 5 and FIG. 9B).

  In Step 3 (Procedure 3), the coordinate value of the reflecting prism 1 after moving in the depth direction (X-axis direction of the survey coordinate system) in Step 2 is again measured (acquired) by the three-dimensional measuring device. When the difference disappears, the locking element 41 as a fixing device is screwed, and the movement of the slider 40 and then the reflecting prism 1 relative to the slide guide rail 30 is restricted and fixed (stopped) at that position (step 3 in FIG. 5). reference).

  In step 4 (procedure 4), subsequently, the three-dimensional coordinate value (current position) of the reflecting prism 2 is measured (acquired) by the three-dimensional measuring device (see procedure 4 in FIG. 6, FIG. 10A). .

  In step 5 (procedure 5), the measured value in the depth direction of the reflecting prism 2 (X-axis direction of the survey coordinate system), the target coordinate value of the reflecting prism 1 (or the actual measured value of the reflecting prism 1), and Is calculated (acquired), and the position of the reflecting prism 2 is moved by rotating the rotary arm 50 around the rotation axis 40A so that the difference is eliminated (step 5 in FIG. 6, FIG. 10B). reference).

In step 6 (procedure 6), the coordinate value of the reflecting prism 2 after the movement in step 5 is again measured (acquired) by the three-dimensional measuring device, and the three-dimensional measuring device in the depth direction (the X coordinate of the survey coordinate system). When the difference disappears, the lock lever 42 is operated in the fixing direction to restrict (fix) the rotation of the rotary arm 50 around the rotary shaft 40A with respect to the slider 40 (see step 6 in FIG. 7, FIG. 11A). ).
Then, the operator draws a line along the straight ruler scale 52 provided at the lower end of the rotary arm 50 (see procedure 6 in FIG. 7 and FIG. 11B).
As a result, the position marking (a straight line that passes through the target X coordinate and is parallel to the Y axis) in the depth direction (X-axis direction of the survey coordinate system) viewed from the three-dimensional measuring device is marked (marking and marking can be performed. )

Next, in Step 7 (Procedure 7), the left and right direction of the reflecting prism 2 (the Y-axis direction of the survey coordinate system in FIGS. The difference between the measured value in the axial direction) and the coordinate value (target coordinate position) of the target position is calculated (acquired), and marking is performed at a position corresponding to the difference with reference to the scale 52 of the rotary arm 50. (See Procedure 7 in FIG. 7, FIGS. 12A and 12B).
As a result, markings are made in the left-right direction (Y-axis direction of the survey coordinate system) and the depth direction (X-axis direction of the survey coordinate system) as viewed from the three-dimensional measurement apparatus. As for the height direction, the top end of the support material is obtained by subtracting the installation height (the height from the lower surface of the slide guide rail 30 to the center of the reflection prism 1) from the height direction coordinate value of the reflection prism 1 or 2. The height of the steel material can be managed from the height of the top.

And an operator installs steel materials on a support material with a crane etc. so that the mark of the steel frame member previously attached to the mark obtained in this way may be matched.
After that, it moves to the installation work of the next steel material.

  As described above, conventionally, the reflecting prism (pin pole prism) is measured while standing on the support material while being supported by the operator's hand. However, according to the present embodiment, the reflecting prism (pin pole prism) is arranged in the third order. Since it can be supported by the original measurement measurement positioning auxiliary device 100, it is not necessary for the operator to hold the reflecting prism (pin pole prism) horizontally during measurement by the total station, so that the burden on the operator can be reduced. It can contribute to the improvement of measurement accuracy and the reduction of measurement time because fluctuations can be suppressed.

  In addition, according to the three-dimensional measurement positioning auxiliary device 100 according to the present embodiment, the direction including the depth direction component (the X coordinate component of the survey coordinate system) related to the three-dimensional measurement device (direction oblique to the depth direction) A movable reflecting prism 1 is obtained, and the reflecting prism 1 is moved in the depth direction to obtain target coordinates in the depth direction (coordinate values in the X-axis direction of the survey coordinate system). By rotating the reflecting prism 2 attached to the rotating front end side of the rotating arm 50 with the reflecting prism 1 as the rotation center, the rotating arm 50 is substantially parallel to the left-right direction (Y-axis direction of the surveying coordinate system) and the target coordinates (surveying). It is brought on a straight line passing through the X-axis direction coordinate value of the coordinate system, and the difference (reflecting prism 1 or reflection) in the left-right direction (Y-axis direction of the surveying coordinate system) along this straight line (rotating arm 50). By subjecting the mark from rhythmic 2 at a position corresponding to the difference) to the target coordinate value (Y-axis direction coordinate value of the survey coordinate system), it can be quickly and out accurately located target coordinate the target position.

  That is, according to the present embodiment, when acquiring the target coordinate position by measuring the coordinate position of the reflecting prism or the like with the three-dimensional measuring device, it is easy and quick, with high accuracy, while being simple and low cost. It is possible to provide a positioning auxiliary device for three-dimensional measurement that can contribute to obtaining a target coordinate position (positioning) and a positioning method using this device.

  Here, the description has been made assuming that the two reflecting prisms 1 and 2 are provided. However, by replacing one reflecting prism (the lower end of the pole can be easily attached and detached with, for example, a screw type). It is also possible for one reflecting prism to function as two reflecting prisms 1 and 2.

  In the present embodiment, the lower end side of the side surface (the side where the three-dimensional measuring device is installed) of the rotary arm 50 to which the scale 52 is attached (attached) is the position of the scale 52 (the short axis of the rotary arm 50). The directional position is indented so that it substantially coincides with the straight line connecting the center of the pole 10 (reflecting prism 1) and the center of the pole 20 (reflecting prism 2). However, the present invention is not limited to this. That is, how much the position of the scale 52 (position in the short axis direction of the rotary arm 50) deviates from the straight line connecting the center of the pole 10 (reflecting prism 1) and the center of the pole 20 (reflecting prism 2). Since it is known in advance that the difference is taken into consideration, it is possible to obtain the same operational effects as the present invention although the labor is slightly increased and the accuracy is slightly decreased by marking.

  The embodiments according to the present invention described above are merely examples for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
