When the irradiation direction of the guide light irradiator is aligned with the collimation axis of the total station and the first guide light is irradiated toward the target point such as the stakeout point, the left and right colors are colored with the collimation axis as the boundary. Since different lights are emitted, it is possible to guide to the collimation axis using this as a mark. Next, when the second guide light is irradiated to a known height such as the prism height at the target point, the color of the light that can be confirmed in the front-back direction of the target point is different based on the known height, so that the movement direction in the front-back direction is different.

The ridgeline of the right-angled mirror coincides with the vertical plane of the optical axis of the lens including the rear focal point of the projection lens so that it is evenly incident on and emitted in the same direction, and between the pair of light sources. The two reflecting surfaces are arranged so as to be at equal angles. According to this aspect, light having different aspects on the left and right can be emitted with the optical axis as the boundary surface.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The embodiments are not limited to the invention, but are exemplary, and all the features and combinations thereof described in the embodiments are not necessarily essential to the invention.

(First Embodiment)
FIG. 1 is a schematic plan view for explaining the configuration of the optical system of the guide light irradiation device 1 according to the first embodiment. In each figure, the rotation angle of the dub prism is different. (A) shows the case where the rotation angle of the dub prism is 0 degree, and (B) shows the case where the rotation angle of the dub prism is 45 degrees.

The guide light irradiation device 1 includes a pair of light emitting diodes 4 and 5, a right-angled mirror 3, a projection lens 6 which is a collimating lens, and a dub prism 7.

The right-angled mirror 3 has two reflecting surfaces 3a and 3b, and the angle formed by the two is configured to be a right angle. The right-angled mirror 3 is arranged on the optical axis L of the projection lens 6 so that the ridges of the reflection surfaces 3a and 3b coincide with the vertical line of the optical axis L passing through the rear focal point of the projection lens 6.

The reflecting surfaces 3a and 3b of the right-angled mirror 3 face the projection lens 6 and are inclined at an equal angle in the direction opposite to the optical axis L.

A red light emitting diode 4 is arranged on the reflected optical axis La of one reflecting surface 3a, and a green light emitting diode 5 is arranged on the reflected optical axis Lb of the other reflecting surface 3b. The red light emitted from the light source 4S of the red light emitting diode 4 is reflected by the reflecting surface 3a, and the green light emitted from the light source 5S of the green light emitting diode 5 is reflected by the reflecting surface 3b, respectively, and is vertical on the optical axis L. The light is incident on the projection lens 6 in a state where the emission color is divided into two by the line.

A dub prism 7 is arranged on the optical axis L in front of the emission surface of the projection lens 6. The dub prism 7 has one of the two inclined surfaces as the incident surface 7a so that the light from the projection lens 6 is incident on the incident surface 7a and the light emitted from the projection lens 6 is incident on the incident surface 7a. Moreover, it is arranged so that its longitudinal direction is parallel to the optical axis L. The dub prism 7 is rotatably supported around the optical axis L, and its rotation angle θ is adjustable.

Here, the dub prism 7 will be described with reference to FIG. FIG. 2 shows the relationship between the rotation angle θ of the dub prism 7 and the state of the image emitted from the dub prism 7, and the rotation angle of the dub prism 7 is different in each of the drawings.

As shown in FIG. 2, the dub prism 7 has an outer shape obtained by extruding an isometric trapezoid having an inclination angle of 45 degrees in the perpendicular direction. One of the two inclined surfaces is an incident surface 7a and the other is an exit surface 7b, and the two inclined surfaces are rotatably supported around the longitudinal direction.

As shown in FIG. 2A, when the dub prism 7 is arranged so that the equiangular trapezoidal surfaces are the upper and lower surfaces, when the image 8A is incident from the incident surface 7a, the image 8B obtained from the exit surface 7b is obtained. , It will be inverted left and right.

When the dub prism 7 is rotated 45 degrees about the longitudinal direction from the state of FIG. 2A, the image 8C obtained from the exit surface 7b is inverted left and right even if the same image 8A is incident from the incident surface 7a. However, the dub prism 7 is rotated 90 degrees in the same direction as the rotation direction (see FIG. 2B).

From the state of FIG. 2A, when the dub prism 7 is rotated 90 degrees about the longitudinal direction, even if the same image 8A is incident from the incident surface 7a, the image 8D obtained from the exit surface 7b is left and right. It is inverted to and rotated 180 degrees in the same direction as the rotation direction of the dub prism 7 (see FIG. 2C).

In this way, when the dub prism 7 is rotated about the axis in the longitudinal direction, the image incident on the incident surface 7a is angled at the same angle as the rotation direction of the dub prism 7 with respect to the rotation angle θ of the dub prism 7. It is emitted in a state of being rotated by 2θ.

Utilizing this property, the guide light irradiation device 1 supports the dub prism 7 so as to be rotatable around the optical axis L and the rotation angle can be adjusted, and the dub prism 7 can be switched at a rotation angle θ of 0 degrees / 45 degrees. It was configured to be.

In this embodiment, with reference to the state of the dub prism 7 shown in FIG. 2A, the state in which the isometric trapezoidal surface is the upper and lower surfaces is defined as a rotation angle of 0 degrees, and the rotation direction in FIG. 2 is positive. The dub prism 7 of 2 (B) was set to a rotation angle of 45 degrees so that both could be switched.

As shown in FIG. 1A, when the rotation angle θ of the dub prism 7 is 0 degrees, the incident light on the incident surface 7a is emitted from the exit surface 7b in a state of being inverted left and right. The incident light on the dub prism 7 is light of different colors on the left and right with respect to the optical axis L, and the emitted light is in a form in which the left and right colors are simply inverted. That is, when the rotation angle θ of the dub prism 7 is 0 degrees, guide lights G having different colors on the left and right are emitted as boundaries with the optical axis L.

As shown in FIG. 1 (B), when the rotation angle θ of the dub prism 7 is 45 degrees, the incident light is the same as the rotation direction of the dub prism 7 from the state of the emitted light in which the rotation angle θ of the dub prism 7 is 0 degrees. It is in a state of being rotated 90 degrees in the direction. That is, when the rotation angle θ of the dub prism 7 is 45 degrees, guide lights G'of different colors at the top and bottom are emitted with the optical axis L as a boundary.

With this configuration, the guide light irradiating device 1 can selectively irradiate both the guide light G having different modes on the left and right and the guide light G'having different modes on the top and bottom.

In the present embodiment, the dub prism 7 is rotatably supported around the optical axis L, the dub prism 7 is rotated by a rotation mechanism (not shown), and the guide light G is adjusted by adjusting the rotation angle θ of the dub prism 7. , G'was configured to selectively irradiate, but by providing a moving mechanism that arranges / removes the dub prism 7 rotated by 45 degrees on the optical axis on the exit surface side of the projection lens, the guide light G, It may be configured so that both G'can be irradiated.

(how to use)
The guide light irradiating device 1 is configured to be capable of irradiating both the guide light G having different modes on the left and right and the guide light G'having different modes on the top and bottom with reference to the optical axis L. By setting the irradiation point as the target point as the pile driving point and switching the guide lights G and G'to irradiate, the worker at the pile driving point confirms the direction by himself in both the left-right direction and the front-back direction. It is possible to move to the vicinity of the pile driving point.

As a method of using the guide light irradiation device 1, a method of setting a pile driving point using the guide light irradiation device 1 will be described with reference to the flowchart of FIG. 3 and FIGS. 4 and 5.

As shown in FIG. 4, the guide light irradiation device 1 is mounted on a total station 2 having a distance measuring / angle measuring function so that the irradiation direction thereof and the collimation direction of the total station 2 substantially coincide with each other.

As step S1, first, the total station 2 is installed at the known point P0.

Next, in step S2, the pile driving point P to be set in the total station 2 is input, and the pile driving point P is collimated by the total station 2.

Next, in step S3, the guide light irradiating device 1 is first irradiated with the guide light G having a different form on the left and right. At this time, the rotation angle θ of the dub prism 7 is 0 degrees. Since the irradiation direction of the guide light G and the collimation direction of the total station 2 are configured to substantially coincide with each other in the horizontal direction, light having different colors on the left and right with respect to the collimation direction of the total station 2 is irradiated as the guide light G. (See FIG. 4 (A)).

Next, in step S4, the operator holding the pole 10 equipped with the prism 9 which is the target of the total station 2 moves in the collimation direction according to the color of the visually recognized guide light G. For example, the guide light G is configured so that the right side is green light and the left side is green light when viewed from the operator. Therefore, when the operator confirms the green light, he / she is more than the pile driving point P. Since you will be on the right side, you can face Total Station 2 and move to the left side of your current location. By checking the color of the guide light G, the operator can confirm whether to move to the left or right, and the operator guides the user to the collimation direction of the total station 2, which is the direction in which the left and right colors of the guide light G look uniform. Will be done. The guide light G guides the vehicle in the left-right direction with respect to the collimation direction.

In the next step S5, the operator remotely controls the guide light irradiation device 1, or the operator of the total station 2 receives a contact and operates the dub prism 7 to rotate the dub prism 7 by 45 degrees. As a result, the guide light G is rotated by 90 degrees, and as shown in FIG. 4 (B), this time, the guide light G'formed by light of different colors at the top and bottom with respect to the irradiation direction (collimation axis) is irradiated. Will be done.

Next, in step S6, the operator confirms the color of the guide light G', grasps the moving direction of the front and rear to the pile driving point P with respect to the collimation direction, and moves to the vicinity of the pile driving point P.

The guidance in the anteroposterior direction in step S6 will be described with reference to FIG. The instrument height of the total station 2 and the prism height of the prism 9 are known, and the prism 9 at the pile driving point P is collimated with the total station 2. FIG. 5 is an explanatory view for explaining the movement in the front-rear direction, and is a view obtained by cutting FIG. 4B in a vertical plane including a known point P0, a stakeout point P, and a collimation axis. The operator has already been guided to this collimation axis, and the front-back direction and the distance to the pile driving point P are unknown.

As shown in FIG. 5, the total station 2 collimates the prism 9 at the pile driving point P, and the guide light G'is a green light on the upper side with reference to the optical axis L (which substantially coincides with the collimation axis). Since the lower side is configured to be red light, the prism height is lower than the instrument height of the total station 2 (lens height of the guide light irradiation light) in this embodiment, based on the height of the prism 9. If it is closer to the total station 2 side than the piling point P, red light is confirmed, and if it is farther than the piling point P, green light is confirmed. The operator can confirm the moving direction by checking the color of the guide light G'by aligning the line of sight with the height of the prism. For example, when the worker is at a point P1 closer to the total station 2 than the pile driving point P, when the pole 10 is erected vertically on the ground and the line of sight is aligned with the prism 9, red light is confirmed. Therefore, it can be determined that the worker should face the total station 2 and move backward. Similarly, if the worker is at a point P2 that is farther than the stakeout point P, when the pole 10 is set up vertically and the line of sight is aligned with the prism 9, green light is confirmed, so it is sufficient to move forward. You can judge for yourself. Guidance in the left-right direction has already been made, and by facing the total station 2 and moving until the upper and lower colors can be seen evenly, guidance is also made in the front-back direction, and it is possible to move to the vicinity of the pile driving point P.

After being guided to the approximate position, the process proceeds to the next step S7. Accurate position confirmation is performed by measuring the distance and angle of the prism 9 provided on the pole 10 of the operator at the total station 2, and the pile driving point P is set.

Next, the process proceeds to step S8. If there is a next pile driving point, the process proceeds to step S9, and a new pile driving point is input to the total station 2. Steps S2 to S8 are repeated until all the pile driving points have been set. The work is completed when there are no more pile driving points to be set.

The guide light irradiating device 1 is configured to be capable of irradiating both the guide light G having different modes on the left and right and the guide light G'having different modes on the upper and lower sides with reference to the irradiation direction, and at the pile driving point P. By irradiating the guide lights G and G'in order, the operator can be guided in both the left-right direction and the front-back direction. By checking the color of the light, the worker himself can determine which way to move, so the guide lights G and G'are guided to the vicinity of the pile driving point P without being guided by others. ..

(Second Embodiment)
FIG. 6 is a schematic plan view for explaining the configuration of the optical system of the guide light irradiation device 101 according to the second embodiment. Similar to FIG. 1, the rotation angle of the dub prism is different in each figure, (A) shows the case where the rotation angle of the dub prism is 0 degree, and (B) shows the case where the rotation angle of the dub prism is 45 degrees. Those having the same configuration as that of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. FIG. 7 is a side view of FIG. 6 (A). In FIG. 7, the light emitting diode is omitted and only each light source is shown. Moreover, the irradiation light is colored and shown for convenience. In addition, for those with overlapping arrangements, the side to be arranged rearward is shown in parentheses. FIG. 8 shows the usage state of the guide light irradiation device 101.

The guide light irradiation device 101 includes a red light emitting diode 4A, 4B, a green light emitting diode 5A, 5B, a right angle mirror 3, a projection lens 6, and a dub prism 7, and includes two pairs of light emitting diodes. different.

The two pairs of the red light emitting diode 4A and the green light emitting diode 5A and the red light emitting diode 4B and the green light emitting diode 5B facing each other across the right angle mirror 3 are arranged vertically symmetrically with respect to the optical axis L in the vertical direction. .. Therefore, when viewed from above, the light emitting diodes of the same color are arranged in an overlapping manner (in FIG. 6, the side to be arranged downward is shown in parentheses).

Similar to the first embodiment, a pair of light emitting diodes having different emission colors form light having different colors on the left and right with the optical axis L as a boundary line in the horizontal direction by the right-angled mirror 3.

As shown in FIG. 7, the light emitted from the light sources 4AS and 5AS of the pair of light emitting diodes 4A and 5A arranged above the optical axis L is reflected by the upper portion of the right-angle mirror 3 and has different colors on the left and right. It is formed on the guide light GA and is incident on the projection lens 6 from slightly above the center as a whole. Similarly, the light emitted from the light sources 4BS and 5BS of the pair of light emitting diodes 4B and 5B arranged below the optical axis L is reflected by the lower portion of the right-angle mirror 3 and becomes the guide light GB having different colors on the left and right. It is formed and is incident on the projection lens 6 from slightly below the center as a whole.

The irradiation directions LA and LB of the guide lights GA and GB are configured to coincide with each other in the horizontal direction and emit light from the projection lens 6 at a predetermined angle β in the vertical direction. Since both the guide GA and GB are formed by the right-angled mirror 3 whose ridge line coincides with the vertical line of the rear focal point of the optical axis L, the boundary lines of the guide light GA and GB coincide in the vertical direction. Further, the angle β is adjusted so as to be smaller than the diffusion angle α in the vertical direction of the guide lights GA and GB emitted from the projection lens 6. By arranging in this way, the guide light GA and GB are partially overlapped at any point, and it is possible to prevent the occurrence of a gap that is not covered by the guide light GA and GB.

What is visually recognized by the operator is the composite guide light SG, which is the composite light of the light emitted from the dub prism 7 with the guide lights GA and GB as incident light. Similar to the first embodiment, when the dub prism 7 is rotated by an angle θ, the composite guide light SG is rotated by 2θ degrees. When the dub prism 7 has a rotation angle of 0 degrees, guide light SGs having different forms on the left and right are emitted (see FIG. 6A), and when the dub prism 7 is rotated 45 degrees, the emitted light is rotated 90 degrees. The composite guide light SG'in which the upper and lower shapes are different is emitted from the exit surface 7b of the dub prism 7 (see FIG. 6 (A)).

FIG. 8 shows a usage state of the guide light irradiation device 101, and is an explanatory diagram for explaining the action and effect. When the composite guide light SG is confirmed from a distance, the composite guide light SG appears not as a state in which multiple light sources are individually separated, but as a single light source in which the brightness when each light source is viewed as a single light source is added. .. Therefore, the synthetic guide light SG is elongated vertically and has a brighter form than the guide light G of the first embodiment.

Since the light reachable distance of the synthetic guide light SG is longer than that of the guide light G of the first embodiment, the working distance of the guide light irradiating device 101 (the distance at which the synthetic guide light SG can be visually recognized) is made longer. Can be done.

Further, by configuring as described above using two pairs of light emitting diodes, the visible range of the combined guide light SG is expanded in the vertical direction, so that it is easier to find and stretches vertically as compared with the first embodiment. The time and effort to search for the synthesis guide light SG is reduced.

The preferred embodiments and modifications of the present invention have been described above, but the above-described embodiments are examples of the present invention, and these can be combined based on the knowledge of those skilled in the art. Included in the scope of the invention.
