Abstract

PURPOSE:To require no technique or skill and to correctly mark a newly-set point in a short time by providing at least two pairs of radiation optical systems, and rotating and radiating laser beams projected from the radiation optical systems to planes orthogonal to each other. CONSTITUTION:If the directions of the laser beams projected from two pairs of light sources 6 are set on the horizontal planes, laser beams L1, L2 from a double-face reflecting member 13 are rotated and radiated onto vertical planes V1, V2 orthogonal to each other. Moreover, if a radiation optical system in the lateral direction from the light source 6 to a radiating lens 8 is horizontal and a radiation optical system in the longitudinal direction is vertical, the laser beam L1 projected by the optical system in the lateral direction is rotated and radiated onto the vertical plane V1, whereas the laser beam L2 projected from the optical system in the longitudinal direction is rotated and radiated onto the vertical planes V1, V2 orthogonal to each other. In the actual use, this machine is mounted to a tripod, the laser beam L1 is agreed with an existing point A and a radiation point is confirmed by the laser beam L2. A newly set point is thus determined.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying machine for construction work that can determine each new construction point on a vertical plane, each new construction point in a perpendicular direction, or each new construction point on a horizontal plane in construction surveying and the like.

0002

[Prior Art] 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.

[0003] Therefore, an example of conventional surveying for setting right angles will be explained with reference to Fig. 6. When establishing a new point C in a direction perpendicular to the existing points A and B, Install. ■Sight the existing point A with theodolite D. ■Turn theodolite D 90 degrees. ■Surveyor E indicates the point to aim at with theodolite D by hand. ■Following the instructions of surveyor E, setting worker F marks the new installation point C. The measurements were carried out using the following procedure.

0004

[Problems to be Solved by the Invention] As mentioned above, when performing construction surveying using conventional surveying equipment and conventional surveying methods, ■ sighting the target with theodolite D, Surveyor E is indispensable in order to rotate the ■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.

[0005]

[Means for Solving the Problems] The present invention basically includes at least two sets of radiation optical systems that emit laser light emitted from a light source as a laser beam, and the two sets of radiation optical systems. The present invention provides a surveying machine for construction work, characterized in that it is equipped with a rotating irradiation device that rotates and irradiates laser beams emitted from the respective planes onto mutually orthogonal surfaces.

As a means for solving the problem more directly, the present invention includes at least two sets of radiation optical systems that emit laser light emitted from a light source as a laser beam, and the two sets of radiation optical systems The present invention provides a construction surveying machine characterized by being equipped with a rotating irradiation device that rotates and irradiates laser beams emitted from a system onto mutually perpendicular vertical planes.

[0007] In addition, in the above-mentioned surveying machine, a semi-transmissive reflector or a semi-transmissive prism is installed to split the laser light emitted from the light source into two directions, and the two split laser lights are emitted as laser beams. The present invention provides a construction surveying machine characterized by being equipped with a set of radiation optical systems.

[0008] Furthermore, in the above-mentioned surveying machine, a radiation optical system for emitting another laser beam is added, and a rotational irradiation device is provided that rotates and irradiates three sets of laser beams onto a vertical plane and a horizontal plane that are perpendicular to each other. The present invention provides a surveying machine for construction use, which is characterized by being equipped with.

[0009] Furthermore, there is provided a construction surveying machine characterized in that, in the above-mentioned surveying machine, a compensator is provided in the radiation optical system to keep the laser beam that is rotated and irradiated always on a vertical plane regardless of the inclination of the machine body. It is something to do.

[Operation] Using the construction surveying machine according to the present invention,
An example of surveying for setting right angles will be explained with reference to FIG. Install it as shown. (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. The procedure is as follows.

[0011] Therefore, compared to the conventional surveying example described above, (1) the surveying engineer E is not required, and it is possible to definitely save one person's labor. ■Techniques and proficiency for turning Theodolite D and sighting the target are not required. - 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 irradiated by the laser beam L2. It has such effects.

On the other hand, in the above-mentioned surveying machine, one of the two sets of laser beams perpendicular to each other is rotated and irradiated onto a horizontal plane, thereby providing a construction surveying machine with an added leveling function.

Furthermore, in the above surveying machine, by adding an optical system that emits another set of laser beams orthogonally to the previous two sets of laser beams, the laser beams can be rotated and irradiated onto a horizontal plane. This has the effect of providing a construction surveying machine that has the added function of a leveling instrument.

Furthermore, in the configuration in which the compensator is provided within the radiation optical system, the rotating laser beam can always be kept vertical regardless of the inclination of the aircraft body.

Reference numeral 4 denotes leveling screws installed at three locations on the bottom plate 5 so as to be height adjustable, which is a so-called leveling device for installing the body 1 in a horizontal state. If the compensator 7, which will be described later, is not provided, a highly sensitive bubble tube (not shown) provided in the aircraft 1 is used as a guide for accurate leveling, but if the compensator 7 is not provided. In this case, it has the function of maintaining the laser beam emitted from the radiation optical system vertically with respect to the inclination of the aircraft body 1, so it is used for rough leveling.

However, it is desirable to provide a previously known fine movement device (for example, the device described in Japanese Utility Model Application No. 137815/1983). 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 beam emitted from the light source 6 into substantially parallel light and emits it. placement) is determined.

As shown in FIG. 1, the present invention includes two sets of radiation optical systems that emit laser light emitted from a light source 6 as a laser beam, and also includes a laser beam emitted from the two sets of radiation optical systems.

The laser beams L1 and L2 emitted from the two-sided reflective member 13 are rotated by

Therefore, if the directions of the laser beams emitted from the two sets of light sources 6 are both set on a horizontal plane, the laser beams L1, emitted from the two-sided reflective member 13,
L2 has a configuration in which rotational irradiation is performed on vertical planes V1 and V2 that are orthogonal to each other, respectively. In addition, in FIG. 1, if the radiation optical system that goes in the horizontal direction from the light source 6 to the radiation lens 8 is horizontal, but if the radiation optical system that goes in the vertical direction is set to be vertical, the radiation in the horizontal direction will be The laser beam L1 emitted from the optical system rotates and irradiates on the vertical plane V1, and the laser beam L2 emitted from the vertical radiation optical system rotates and irradiates on the horizontal plane.

In this case, by adding a radiation optical system to the two sets of radiation optical systems, in which the optical axes of the light source 6 and the radiation lens 8 are located in the direction perpendicular to the plane of the paper in FIG. The laser beam emitted from the radiation lens 8 in the vertical direction is projected toward the two-sided reflective member 13, and the third laser beam L3 from the two-sided reflective member rotated by the motor 15 rotates on the horizontal plane H. It can be configured to be emitted to irradiate.

In the embodiment shown in FIG. 3, when the paper surface is horizontal, a light source 6 is emitted on the paper surface and a compensator 7 is moved horizontally on the paper surface.
A semi-transmissive reflecting mirror 11 is installed in the optical path of the laser beam heading toward the radiation lens 8, and approximately half of the light is reflected by the reflecting mirror 11 in the vertical direction on the paper surface. The transmitted laser beam with approximately half the amount of light continues in the horizontal direction, and these two sets of laser beams that are orthogonal to each other are rotated by motors 15, respectively.
The surface reflecting member 13 causes laser beams L1 and L2 to be perpendicular to the plane of the paper and to each other.
It is configured to be rotated and irradiated onto V2, and has a configuration substantially identical to that of FIG. 1, except that the amount of light is approximately halved. Note that the semi-transparent reflecting mirror 1
1 can also be replaced with a semi-transparent prism.

The embodiment shown in FIG. 4 is a different embodiment from the above-mentioned embodiment, in which a laser beam L3 that rotates and irradiates on the horizontal plane H is added to the embodiment shown in FIG. That is, in the embodiment of FIG. 4, a semi-transmissive mirror 12 that reflects approximately half the amount of light of the laser beam in the vertical direction is installed behind the radiation lens 8 of the embodiment of FIG.
The laser beam L1 with approximately 1/2 the amount of light transmitted through the semi-transparent reflector 12 is rotated and irradiated on the vertical plane V1 by the two-sided reflector 13, whereas the reflected laser beam L3 is reflected by the two-sided reflector 13 on the horizontal plane. It is configured so that rotational irradiation is performed on H.

In the above embodiments, the rotating two-sided reflective member 13 is depicted as being directly connected to a motor, but it may be configured to be rotated by a power transmission mechanism using a pulley, gears, or the like. is of course possible. Furthermore, it is a common sense measure to consolidate each motor 15 into one or two motors and configure the two-sided reflective member 13 to rotate in conjunction with a pulley, gear, or the like.

The two-sided reflective member 13 and the motor 15 each constitute a rotating irradiation device according to the present invention, and in FIG. Then, the control signal is received on the aircraft S side, and the rotation speed of the laser beam can be adjusted including stopping, and the power switch can be turned on and off.
It is also possible to have a configuration in which FF is used, and a configuration in which remote control is possible. 9 is an electronic circuit that drives the light source 6 and the motor 15, etc.; 10 is a power source that drives the electronic circuit 9, the light source 6, the motor 15, etc.; and 16

In the embodiment having the above configuration, the mode of use of the surveying machine of the present invention will be explained based on the survey mode diagram shown in FIG. When setting, first, the construction surveying machine S according to the present invention is mounted on a tripod T, and the laser beams L1 and L are
The intersection point B' of the two points is set to be located on the vertical line of the existing point B.

At this time, the position of the intersection B' with respect to the existing point B is determined by the swing P or the centripetal telescope (
This is confirmed by a known method (not shown). Next, the laser beam L1 is made to coincide with the existing point A, but at this time,
If the laser beam is visible light, the match is confirmed visually, but if it is invisible light, the match is confirmed using a detector. Then, by marking the point to be irradiated with the laser beam L2, 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. Also,

[0029]

[Effects] The construction surveying machine according to the present invention having the above configuration has the following effects. ■In the conventional surveying method using theodolite D, it is necessary for the surveyor E to raise the telescope and focus it, but when aligning the laser beam L1 with the existing point A, the laser Since the beam L1 rotates and irradiates on a vertical plane, it can be easily matched regardless of the distance or height of the existing point.

■Once the machine S is installed, the new installation point can be found without operating the machine at all.
Since surveying engineer E is not required, the labor of one person can be definitely saved. ■In the conventional surveying method using theodolite D, it is necessary for the surveyor E to tilt the telescope prone and focus at each new point, and to indicate the new point, whereas the laser beam L2 Since the beam is rotated and irradiated on a vertical plane, any number of newly installed points can be found without operating the machine S, regardless of distance, distance, or height.

■The surveying machine according to the present invention not only uses the right angle setting, but also uses the laser beam L1 or L2,
It can also be used to set the vertical plane, and the laser beam L1
By finding the intersection of and L2, it can also be used to set a vertical line. (2) In addition, in a configuration in which a compensator is provided within the radiation optical system, the rotating laser beam can always be kept vertical regardless of the tilt of the aircraft.

[0032]Furthermore, in a device having a configuration including a rotating irradiation device for rotating and irradiating a laser beam onto a horizontal plane, it can also be used for setting the horizontal plane, and can also be used in place of a leveling instrument.

[0033] Also, in the case of a device having a configuration with an individual radiation optical system that emits the laser light emitted from the light source as a laser beam, the configuration is simple, and since there are few reflective surfaces, there is less light loss, and the laser beam Since there is no need to distribute the laser beam, the amount of light emitted from the laser beam can be increased and it can be used over a longer distance.

■Furthermore, the laser beam emitted from the light source is
In a configuration with a semi-transparent reflector or a semi-transparent prism that branches in different directions, and two sets of radiation optical systems that emit the two branched laser beams as laser beams, the light source can be shared, so the power consumption is reduced. Since the battery can be saved, the usage time can be extended when using a battery as a power source.
