Abstract

PURPOSE:To enable marking operation to be executed accurately in a short time and man-hours to be saved by rotating and emitting two laser beams which are branched by a beam splitter onto vertical surfaces which cross each other. CONSTITUTION:With a laser beam which is discharged from a discharge lens 8, a quantity of light of nearly half is reflected toward a reflection mirror 12 by a semi-transmission reflection mirror 11 constituting a beam splitter and the reflected laser beam is reflected toward a surface reflection member 13 by the reflection mirror 12. The member 13 is rotated by a motor 15 and a laser beam L1 which is discharged from the member 13 is rotated and emitted on a vertical surface V1. On the other hand, a laser beam with light having nearly half quantity which is transmitted through a semi-transmission reflection mirror 11 is directed toward another double-surface reflection member by a double-surface reflection member 28 and laser beam is rotated and emits light on a vertical surface which crosses the vertical surface V1 according to rotation of the double-surface reflection member by the use of a motor.

[Conventional technology] Prior to construction, in construction surveying to determine the new construction point that will serve as the reference point for construction, there may be surveys that set various angles, but most of them are surveys that set right angles. This can be easily understood from the fact that the majority of buildings are constructed from right angles.

Therefore, the 71st example of conventional surveying for setting right angles!

[Problems to be solved by the invention] As mentioned above, when construction surveying is carried out using conventional surveying equipment and conventional surveying methods, ■ Theodolite D
A surveyor E is indispensable in order to standardize the target and rotate the theotrite D.

■These tasks require skill and skill.

■The marking work for the new installation point C is done indirectly by the setting worker F in accordance with the instructions of the surveyor E, so it takes time and tends to be uncertain.

There were some problems.

[Means for Solving the Problems] Therefore, the present invention provides a beam splitter composed of a semi-transmissive reflecting mirror or a semi-transmissive prism that splits a laser beam emitted from a light source, a radiation optical system, etc. into two directions, and The present invention provides a construction surveying machine equipped with a rotating irradiation device that rotates and irradiates the two branched laser beams on vertical planes perpendicular to each other. Provided is a surveying machine for construction work, characterized in that a convenser is provided in a radiation optical system to keep a rotating laser beam irradiated on a vertical plane regardless of the inclination; The present invention provides a surveying machine for construction work, which is characterized in that it is equipped with a beam splitter that splits one laser beam, and a rotating irradiation device that rotationally irradiates the laser beam onto a horizontal surface.

[Function] An example of surveying for setting right angles using the construction surveying machine according to the present invention will be explained with reference to FIG. 6. ■The construction surveying machine S according to the present invention is located near the machine S. The laser beams are installed so that the intersection B' of the laser beams Ll and L2 coincides with the existing point B.

(2) Align one rotating irradiation laser beam L1 with the existing point A.

(2) The setting operator F directly marks the point irradiated by the other laser beam L2 perpendicular to the laser beam L1.

Compared to the conventional survey example described above, fI411 engineer E is not required, and it is possible to definitely save one person's labor.

■Techniques and proficiency in turning the Theodolite D and standardizing the target are not required.

■The marking work for the new point C can be done in a short time and is accurate because it is sufficient to directly mark the point where the laser beam L2 is irradiated.

On the other hand, by adding a beam splitter to the above-mentioned surveying machine,
Furthermore, by providing another laser beam as a branch and rotating and irradiating the laser beam onto a horizontal surface, there is an effect of providing a surveying machine for construction work that has the added function of a leveling instrument.

[Example] Hereinafter, the configuration of the present invention will be described in detail based on the illustrated example.

In the embodiment of the present invention shown in FIGS. 1 to 3, reference numeral 5 denotes a bottom plate with a joint for attaching the machine S in FIG. 6 to the tripod T. Reference numeral 4 denotes a so-called leveling device that sets the aircraft l in a horizontal state using leveling racks installed at three height-adjustable locations with respect to the bottom plate 5. , If the conventator 7 described later is not available, a highly sensitive bubble tube (not shown) provided on the aircraft l is used as a guide for accurate leveling, but if the conventator 7 is available is used for rough leveling because it has the function of maintaining the laser beam emitted from the radiation optical system vertically with respect to the inclination of the m-body 1. The shaft B is a rotating shaft for directing the laser beam Ll (or L2) to the existing point, and is attached to the bearing stand 3.
Although not shown, it is supported by a previously known fine movement device (for example, Utility Model Application No. 63-13781).
It is desirable to install the device described in Publication No. 5).

Reference numeral 6 denotes a light source, and although it is desirable to use a laser diode to make the aircraft compact, it is also possible to use a HeNe gas laser in principle. Reference numeral 8 denotes a radiation lens, which converts the laser light emitted from the light source 6 into substantially parallel light and emits it. 6
The lens configuration (type, number, and arrangement of lenses) is determined according to the convenser 7 and the convenser 7. Approximately half of the light intensity of the laser beam emitted from the radiation lens 8 is reflected by the semi-transparent reflector 11 toward the reflector 12, and the reflected laser beam is further directed by the reflector 12 to the two-sided reflective member 13. It is constructed so that it is reflected by the light. Note that the semi-transparent reflection fi11 can be replaced with a semi-transparent prism. In addition, the configuration (shape, number, etc.) of the reflecting mirror 12 and the reflection U (reflection direction, number of reflections, etc.) are as follows:
Various configurations can be made, but these are determined depending on the presence or absence of the conventor and the corrective action of the conventor to be provided. Then, two-sided reflection meter material 1
The laser beam L1 rotated by a motor 5 and emitted from the two-sided reflective member 13 is configured to rotate and irradiate a vertical plane Vl.

On the other hand, the laser beam having approximately half the amount of light transmitted through the semi-transmissive mirror 11 is directed to the two-sided reflecting member 23 by the two-sided reflecting member 28, and the laser beam is directed to the two-sided reflecting member 23.
By rotating the two-sided reflective member 23 by the angle 5, the vertical plane 2 is rotated and irradiated as L2.

Note that the two-sided reflective member 28 is composed of a prism or a reflective mirror, and its configuration (shape, number, etc.) and reflection mode (reflection direction, number of reflections, etc.) can be considered in various ways; This is determined depending on the presence or absence of the convenser and the corrective action of the conventor to be installed.

At this time, the rotation axis of the two-sided reflective member 230 is 90 degrees horizontally relative to the rotation axis of the two-sided reflective member 13.
The vertical planes ■1 and ■2 are arranged at different positions by 0 degrees, and as a result, the two laser beams Ll and L2 rotate and irradiate the vertical surfaces ■1 and ■2.
form vertical planes perpendicular to each other.

The embodiment shown in FIG. 4 is a different embodiment from the above, in which a laser beam L3 that rotates and irradiates the horizontal surface H is added to the above embodiment.

That is, in the embodiment shown in FIG. 4, the semi-transparent reflection fill in the previous embodiment is changed to the semi-transmission reflection @ill' which transmits approximately 2/3 of the amount of light, and the two-sided reflection fill in the previous embodiment is changed. material 28
The configuration is changed to a transflective mirror 21 that transmits approximately 1/2 the amount of light and a reflective ff22.

Approximately 1/3 of the total amount of light transmitted through the transflector 2
The laser beam having the amount of light is configured to be rotated and irradiated onto the horizontal plane H as L'3 by rotating the two-sided reflecting member 330 by the motor 35.

Here, the semi-transparent reflecting mirror 21 can be replaced with a semi-transparent prism as described above.

In addition, in the above embodiment, the rotating two-sided evaluation material 13
．． Although both 23 and 33 are depicted as being directly connected to a motor, it is of course possible that they be configured to be rotated by a power transmission mechanism using a pulley, gears, or the like.

It is also common sense to combine the motors 15.25 and 35 into one or two motors, and to configure the two-sided reflective material 13.23 and U33 to rotate in conjunction with a pulley or gear. It is a means of obtaining.

The two-sided reflecting member 13, 23, 33 and the motor 15, 26, 35 each constitute a rotating irradiation device according to the present invention, and in FIG. A control signal is transmitted by the controller, and the control signal is received on the aircraft S side to adjust the rotation speed of the laser beam, including stopping it, and to turn the power switch ON/OFF, allowing for remote control. You can also do that.

And 9 is the light source 6 and the motor 15, 25.35
10 is an electronic circuit for driving the electronic circuit 9 and the light source 6. There is a power source for driving the motors 15, 25, 35, etc., 16, 26, 36 is a laser beam emission window of the rotating irradiation device, 14, 24, 34 is a two-sided reflective member support frame, 17, 27. 37 is a motor support frame.

FIG. 5 is a diagram showing still another embodiment, in which the radiation lens 8
By positioning the laser beam indexed from the horizontal direction, the two-sided splitting member 28 is omitted from the embodiments shown in FIGS. 1 and 2.

That is, approximately half of the light intensity of the laser beam indexed from the radiation lens 8 is horizontally reflected by the semi-transmissive reflector 11 toward the bifacially divided member 13, and then reflected from the bifacially reflective member 13 rotated by the motor 5. Emitted laser beam Ll
is configured to rotate pg on the vertical plane vl, while the laser beam with approximately half the amount of light transmitted through the semi-transparent reflection fill is directed horizontally to the two-sided reflection member 23, and the laser beam The beam is configured to be rotated and irradiated onto the vertical plane v2 as L2 by rotating the two-sided wound ablation material 23 by the motor 25.

Number 51 above! As in the embodiment 1, a transflective mirror 11
The laser beam reflected by the laser beam is directed directly to the two-sided reflective material 13. Therefore, it is possible to omit the reflective mirror 12 of the embodiment shown in FIG.
A two-sided splitting member 23 that rotates the laser beam that has passed through the
By directly cutting into large portions, the two-sided reflective material 28 of the previous embodiment can be omitted.

Further, as described above, in the embodiment shown in FIG. 4, the reflecting mirror 22 can be omitted by directing the laser beam reflected by the semi-transparent reflecting mirror 21 to the two-sided reflecting member 23.

In the embodiment with the above configuration, the use of the surveying machine of the present invention will be explained based on the surveying mode diagram shown in FIG. 6. A new point C is set in a direction perpendicular to the existing points A and Bc. In this case, first, the construction surveying machine S according to the present invention is installed on the third IIT, and the intersection point B' of the laser beams L1 and L2 is set to be located on the vertical line of the existing point B. At this time, the position of the intersection point B' with respect to the existing point is confirmed by the swing P or the centripetal telescope (known in the art, not shown) installed on the machine S. Next, the laser beam Ll is made to coincide with the existing point A. At this time, if the laser beam is visible light, the coincidence is confirmed visually, but if it is invisible light, the coincidence is confirmed with a detector. Then, by marking the point where the laser beam L2 is directed to irradiate, a new point C that is perpendicular to the existing points A and B is determined. In this case as well, if the laser beam is invisible light, the new point C is determined by the detector.

In addition, in the case of the configuration in which the laser beam L3 is rotated and irradiated on the horizontal ff1H in the embodiment shown in FIG. can be immediately obtained from

[Effects] The construction surveying machine according to the present invention having the above configuration has the following effects.

■In the conventional surveying method using the heptaodolite D, surveying engineer E requires additional tilting and tilting of the telescope, but when aligning the laser beam Ll with the existing point A, Laser beam L1 rotates on a vertical plane! ! ! ? Since the existing points are visible, they can be easily matched regardless of the distance or height of the existing points.

■Once the IjI machine S is installed, new installation points can be determined without operating the machine at all, and surveying engineer E is not required, so the labor of one person can be definitely saved.

■In the conventional surveying method using theodoray) D, it is necessary for the surveyor E to raise the telescope prone and focus at each new point, as well as to indicate the new point, whereas the laser beam Since L2 rotates and irradiates on a vertical plane, any number of newly installed points can be found without operating the machine S, regardless of distance or height.

■The surveying machine according to the present invention can be used not only for setting right angles, but also for setting vertical planes by using laser beams Ll or L2, and by finding the intersection of laser beams L1 and L2. It can also be used to set lines.

(2) Furthermore, in a configuration in which a convenser is provided in the radiation optical system, the rotating laser beam can always be kept vertical regardless of the tilt of the aircraft.

■Furthermore, in those equipped with a rotating irradiation device that rotates and irradiates a laser beam onto a horizontal surface,
It can also be used to set the horizontal plane, and can also be used in place of a leveling instrument.
