Description

Technical Field

[0001] The present disclosure relates to a method for installing installation equipment. and Surveying system Mu It is related.

Background Art

[0002] When installing installation equipment in installation work such as electronic toll collection system (ETC: Electronic Toll Collection System) work, it is necessary to perform three adjustment operations: the height of the installation equipment, the inclination of the installation equipment, and the mutual position of two installation equipments.

[0003] Conventionally, there is a method of using an auto level to adjust the height of installation equipment. In the method of using an auto level, the auto level is installed at a position where both a point A serving as a height reference and a point B whose height is to be measured can be seen. One surveyor stands at point A and holds a leveling rod, and another surveyor looks into the auto level and checks the scale of the leveling rod. Also, one surveyor stands at point B and holds a leveling rod, and another surveyor looks into the auto level and checks the scale of the leveling rod. The height of point B is calculated from the height difference between the two points A and B, and the height of point B is adjusted by leveling the ground at point B horizontally or adding soil at point B to the required height. However, in the method of using an auto level, there may be variations in the measured values for each surveyor depending on how the leveling rod is held and how the auto level is viewed. Also, in the method of using an auto level, there is a problem that at least two surveyors are always required. Also, in the method of using an auto level, since the surveyor needs to adjust the height of point B while looking at the bubble tube of the auto level, there is a problem that a great deal of time and labor are required for the adjustment work.

[0004] Traditionally, one method for adjusting the tilt of installed equipment is to use a plumb bob. In this method, a plumb bob holder is attached to the equipment to be checked for perpendicularity to the ground, and a string is extended from the holder until the weight almost touches the ground. After the weight stops swinging, the horizontal distance from the side of the equipment to the string is measured at two points: the upper part of the equipment near the plumb bob holder and the lower part near the weight. This confirms whether the equipment is perpendicular to the ground. If the equipment is not perpendicular to the ground, its tilt is adjusted. However, with the plumb bob method, the weight may swing due to wind, making it difficult to accurately measure the horizontal distance. Furthermore, with the plumb bob method, strong winds can cause the weight to swing for a long time, which is a problem.

[0005] Traditionally, one method for adjusting the relative positions of two installed pieces of equipment is to mark them out. In this method, two reference points marked on the design drawing, which indicates the installation positions of the two pieces of equipment, are copied to the construction site, and a guideline is drawn by connecting the two reference points. Then, a reference line is drawn parallel to the guideline at a distance from it, and this reference line is used as the centerline of the two installed pieces of equipment. This determines the relative positions of the two installed pieces of equipment. However, a problem with this method is that if a reference line parallel to the guideline cannot be drawn at a distance from it, the installation location of the equipment cannot be accurately determined. Furthermore, even if the installation location of the equipment can be accurately determined using this method, it is difficult to accurately determine the orientation of the equipment.

[0006] One method for marking out locations is to use a laser level that projects a laser in a straight line or cross shape. In this method, the laser level is placed on the ground, and the laser is projected onto the ground. The relative positions of two installed pieces of equipment are determined by visually observing the laser projected onto the ground as a horizontal or vertical line. However, a problem with this method is that if the laser level is used in a bright place with sunlight, the laser projected onto the ground may not be visible.

[0007] As a way to solve these problems, Patent Document 1 discloses a technology in which the housing of a light receiver that receives a laser emitted from a laser level is a cubic case, one side of the housing is opened as a light inlet, and a light-receiving surface colored to be approximately the same color as the wavelength of the laser is provided inside the housing. According to the technology disclosed in Patent Document 1, even in bright places exposed to sunlight, the laser emitted from the laser level is reflected by the light-receiving surface colored to be approximately the same color as its wavelength, and the part of the light-receiving surface that is hit by the laser shines brightly, thus making the laser visible. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2009-58494 [Overview of the project] [Problems that the invention aims to solve]

[0009] Conventional adjustment methods only adjust one of three aspects: the height of the installed equipment, the tilt of the installed equipment, or the relative position of two installed equipment units. Therefore, when performing all three adjustment tasks, it is necessary to use different equipment and methods for each of the three adjustment tasks. This results in the time and effort required to prepare the equipment used for multiple adjustment tasks, which prolongs the construction period of the installation work.

[0010] This disclosure is made in view of the above, and aims to provide a method for installing installation equipment that can reduce the time and effort required to prepare equipment by standardizing some of the equipment used in multiple adjustment operations. [Means for solving the problem]

[0011] To solve the above-mentioned problems and achieve the objective, the installation method for installation equipment according to this disclosure is an installation method for installing installation equipment on an installation surface during installation work, and uses a surveying system. The surveying system comprises a laser oscillator, a stand for the laser oscillator, a laser catcher, and multiple types of stands for the laser catcher. The laser oscillator emits a laser. The stand for the laser oscillator is a stand for attaching the laser oscillator to the installation equipment or installation surface, and the state of the laser oscillator can be changed between a first vertical position in which the laser is irradiated in a horizontal plane and a first horizontal position in which the laser is irradiated in a vertical plane. The laser catcher receives the laser. The laser catcher is provided with a laser receiving reference line that indicates the correct irradiation position of the laser. The laser catcher notifies the deviation between the received laser and the laser receiving reference line at least visually and audibly. Multiple types of stands for the laser catcher are stands for attaching the laser catcher to the installation equipment. The laser catcher stand is selected from a laser catcher stand that holds the laser catcher in a second vertical position where the laser receiving reference line is located in the horizontal plane, and another laser catcher stand that holds the laser catcher in a second horizontal position where the laser receiving reference line is located in the vertical plane. The installation method of the installation equipment according to this disclosure includes a laser oscillator installation step, a laser catcher installation step, an irradiation step, and an adjustment step. The laser oscillator installation step involves changing the orientation of the laser oscillator stand to which the laser oscillator is attached, so that the laser oscillator is in a first vertical position or a first horizontal position, and then installing the laser oscillator on the installation equipment or installation surface via the laser oscillator stand. The laser catcher installation process involves selecting one type of laser catcher stand from several types of laser catcher stands, using the selected stand to hold the laser catcher in either a second vertical or second horizontal position, and then installing the laser catcher to the mounting equipment via the laser catcher stand.The irradiation process involves irradiating the laser catcher with a laser from the laser oscillator. The adjustment process involves adjusting the height of the installed equipment, the tilt of the installed equipment, and the relative position of the two installed equipment while visually and audibly confirming the discrepancy between the received laser and the laser receiving reference line. [Effects of the Invention]

[0012] According to this disclosure, by standardizing some of the equipment used in multiple adjustment operations, the time and effort required to prepare the equipment can be reduced. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0014] The installation method of the installation device according to the embodiment will be described below and Surveying system Mu It will be described in detail based on the drawings

[0015] Embodiment 1. First, the surveying system 1 used in the installation method of the installation equipment 9 and 10 will be described with reference to Figures 1 to 3. Figure 1 is a perspective view showing the installation method of the installation equipment 9 according to Embodiment 1, and shows the adjustment process of adjusting the height of the installation equipment 9 using the surveying system 1. Figure 2 is a perspective view showing the installation method of the installation equipment 9 according to Embodiment 1, and shows the adjustment process of adjusting the inclination of the installation equipment 9 using the surveying system 1. Figure 3 is a perspective view showing the installation method of the installation equipment 9 and 10 according to Embodiment 1, and shows the adjustment process of adjusting the relative positions of the two installation equipment 9 and 10 using the surveying system 1.

[0016] The surveying system 1 is a system for performing three adjustment tasks during installation work: adjusting the height of the installed equipment 9, adjusting the inclination of the installed equipment 9, and adjusting the relative positions of two installed equipment devices 9 and 10. In this embodiment, the case in which the installation work is for an electronic toll collection system (hereinafter referred to as "ETC") is illustrated. The surveying system 1 comprises a laser oscillator 2, a stand for the laser oscillator 3, a laser catcher 4, and several types of stands for the laser catcher 5, 6, and 7. The common laser oscillator 2, stand for the laser oscillator 3, and laser catcher 4 are used for each of the three adjustment tasks. On the other hand, the stand for the laser catcher 5 is used for adjusting the height of the installed equipment 9, and the stand for the laser catcher 6 or stand for the laser catcher 7 is used for adjusting the inclination of the installed equipment 9 and adjusting the relative positions of the two installed equipment devices 9 and 10. In other words, the installation method for the installation equipment 9 and 10 using the surveying system 1 involves using the laser 2a for adjustments in three adjustment operations, and some of the equipment used in these three adjustment operations is standardized.

[0017] The laser oscillator 2 automatically levels itself horizontally or vertically and emits a laser 2a for marking. In Figures 1 to 3, the laser 2a is illustrated with dot hatching. The laser oscillator 2 is a rotating laser device. The laser oscillator 2 has a rotating head 2b. The rotating head 2b has a laser light source such as a light-emitting diode, a semiconductor laser, or an SLED (Super Luminescent Diode). The laser oscillator 2 is installed on the mounting equipment 10 or the mounting surface via a laser oscillator stand 3. The laser oscillator 2 rotates the rotating head 2b to rotate the laser 2a so that it revolves in a horizontal or vertical plane.

[0018] The laser oscillator stand 3 is a stand for mounting the laser oscillator 2 to the installation equipment 10 or the mounting surface. The laser oscillator stand 3 can change the state of the laser oscillator 2 between a first vertical orientation, where the laser 2a is irradiated in a horizontal plane, as shown in Figure 1, and a first horizontal orientation, where the laser 2a is irradiated in a vertical plane, as shown in Figures 2 and 3. The laser oscillator stand 3 can be used to install the laser oscillator 2 on the mounting surface in the first vertical orientation, as shown in Figure 1; to install the laser oscillator 2 on the mounting surface in the second horizontal orientation, as shown in Figure 2; and to install the laser oscillator 2 on the installation equipment 10 in the second horizontal orientation, as shown in Figure 3. Details of the first vertical orientation and the first horizontal orientation will be described later.

[0019] Figure 4 is a perspective view showing the laser oscillator stand 3 when the laser oscillator 2 is in the first vertical position. Figure 5 is a perspective view showing the laser oscillator stand 3 when the laser oscillator 2 is in the first horizontal position. Figure 6 is a perspective view showing the laser oscillator stand 3 when the laser oscillator 2 is in the first horizontal position, and is viewed from a different angle than Figure 5. As shown in Figure 4, the laser oscillator stand 3 comprises a first support part 3a, a first adjustment screw 3b, a second support part 3c, a second adjustment screw 3d, a laser blocking arm 3e, a position adjustment operating part 3f, a pair of clamping parts 3g, 3h, and a clamping screw 3i. When describing each component of the laser oscillator stand 3, two directions orthogonal to each other in the same plane are referred to as the first direction A and the second direction B, and the direction orthogonal to the first direction A and the second direction B is referred to as the third direction C. Figure 4 and others illustrate arrows indicating the first direction A, the second direction B, and the third direction C. In the first direction A, the second direction B, and the third direction C, the direction pointed to by each arrow is referred to as one side, and the opposite side as the other side.

[0020] The first support portion 3a is a plate-shaped part extending in a first direction A and a second direction B that are orthogonal to each other within the same plane. The outer shape of the first support portion 3a is generally rectangular. A laser oscillator 2 that irradiates with a laser 2a is fixed to the first support portion 3a. As shown in Figure 6, the first support portion 3a has a support frame 3j and a movable portion 3k. The shape of the support frame 3j is rectangular. One rectangular screw mounting piece 3m is provided at each of the four corners of the support frame 3j. The shape of the movable portion 3k is rectangular so that it can be housed inside the support frame 3j. The movable portion 3k is movable in a third direction C relative to the support frame 3j. The laser oscillator 2 is fixed to the movable portion 3k.

[0021] The first adjustment screw 3b is attached to the first support portion 3a and is rotatable about the third direction C as an axis. One first adjustment screw 3b is attached to each screw mounting piece 3m of the first support portion 3a.

[0022] As shown in Figure 4, the second support portion 3c is a plate-shaped portion extending from one end of the first support portion 3a in the first direction A to the third direction C. The second support portion 3c can be positioned between the laser oscillator 2 and the installation equipment 10 (see Figure 3) in the first direction A. The second support portion 3c has two through holes 3n and 3o that penetrate in the first direction A. The two through holes 3n and 3o are spaced apart from each other in the third direction C. Between the two through holes 3n and 3o is a plate-shaped operating and holding portion 3p that extends in the second direction B and the third direction C. One through hole 3n is positioned to the other side of the third direction C from the operating and holding portion 3p. The other through hole 3o is positioned to the one side of the third direction C from the operating and holding portion 3p. The second support portion 3c is provided with an L-shaped screw mounting portion 3q. The screw mounting portion 3q extends from one end of the second support portion 3c in the second direction B toward one side of the second direction B, and then extends toward the other side of the first direction A.

[0023] The second adjustment screw 3d is a screw that is attached to the second support portion 3c and is rotatable about the second direction B as an axis. One second adjustment screw 3d is attached to the screw mounting portion 3q of the second support portion 3c.

[0024] The laser blocking arm 3e is an elongated plate-shaped portion that is rotatably attached to the second support portion 3c via a rotation axis 3r extending in the third direction C. The position of the laser blocking arm 3e can be changed between a blocking position that blocks a portion of the laser 2a emitted from the laser oscillator 2 (see solid lines in Figures 4 and 5) and a non-blocking position that does not block the laser 2a emitted from the laser oscillator 2 (see dashed lines in Figures 4 and 5). When the laser blocking arm 3e is in the blocking position, it blocks the irradiation port of the rotating head 2b from the other side of the second direction B, and extends in the first direction A and the third direction C, perpendicular to the second support portion 3c. When the laser blocking arm 3e is in the non-blocking position, it is away from the irradiation port of the rotating head 2b, and extends in the second direction B and the third direction C, parallel to the second support portion 3c.

[0025] As shown in Figure 4, the position adjustment operating section 3f is a member that can adjust the position of the movable section 3k in the third direction C. The position adjustment operating section 3f has an operating handle 3s and an operating screw section 3t. The position adjustment operating section 3f is held in the operating holding section 3p so as to be rotatable about the third direction C as an axis. The shape of the operating handle 3s is cylindrical. The operating handle 3s is positioned so as to be exposed from the through hole 3o. One end of the operating screw section 3t in the third direction C is fitted inside the operating handle 3s. The operating screw section 3t rotates in conjunction with the rotation of the operating handle 3s. The operating screw section 3t is positioned between the laser oscillator 2 and the second support section 3c in the first direction A. The operating screw section 3t extends from the operating handle 3s toward the first support section 3a. The other end of the operating screw section 3t in the third direction C is fixed directly or indirectly to the movable section 3k. By rotating the operating handle 3s around the third direction C as an axis, the operating screw portion 3t can be rotated, thereby adjusting the positions of the movable portion 3k and the laser oscillator 2 in the third direction C.

[0026] A pair of clamping portions 3g and 3h extend from the second support portion 3c toward the opposite side of the first support portion 3a in one direction of the first direction A, and are spaced apart from each other in the third direction C. One clamping portion 3g is located at the same position as one through hole 3n in the third direction C. One clamping portion 3g includes two plate pieces positioned opposite each other across the through hole 3n. Each plate piece is a plate-shaped portion extending in the first direction A and the second direction B. The other clamping portion 3h is located at one end of the second support portion 3c in the third direction C. One end of the second support portion 3c is the end opposite to the end connected to the first support portion 3a. The other clamping portion 3h is a plate-shaped portion extending in the first direction A and the second direction B.

[0027] The clamping screws 3i are screws that are rotatably attached to one of the clamping parts 3g around a third direction C. In this embodiment, one clamping screw 3i is attached to each plate piece of one of the clamping parts 3g. Each clamping screw 3i penetrates one of the clamping parts 3g in the third direction C. By rotating each clamping screw 3i around the third direction C, the clamping screws 3i can move closer to and further away from the other clamping part 3h. By bringing the clamping screws 3i closer to the other clamping part 3h in the third direction C, it is possible to clamp the mounting equipment 10 between the clamping screws 3i and the other clamping part 3h, and the laser oscillator stand 3 can be attached to the mounting equipment 10. On the other hand, by moving the clamping screws 3i away from the other clamping part 3h in the third direction C, the laser oscillator stand 3 can be removed from the mounting equipment 10.

[0028] A plate-shaped cushioning material 3u is attached to the portion of the second support portion 3c that faces the installed equipment 10. Similarly, a plate-shaped cushioning material 3u is attached to the portion of the other clamping portion 3h that faces the installed equipment 10, and a cylindrical cushioning material 3u is attached to the portion of the clamping screw 3i that faces the installed equipment 10. The cushioning materials 3u serve to suppress damage to the installed equipment 10 caused by contact between the installed equipment 10 and the laser oscillator stand 3. The cushioning material 3u is, for example, a monomer-cast nylon pad.

[0029] Here, with reference to Figures 1 to 6, the first vertical orientation and the first horizontal orientation will be explained in detail. In the following explanation, two directions perpendicular to each other in the horizontal plane will be referred to as the first horizontal direction a and the second horizontal direction b, and the direction perpendicular to the first horizontal direction a and the second horizontal direction b will be referred to as the vertical direction c. Figures 1 and others illustrate arrows indicating the first horizontal direction a, the second horizontal direction b, and the vertical direction c. In the first horizontal direction a, the second horizontal direction b, and the vertical direction c, the direction pointed to by each arrow will be referred to as one side, and the opposite side as the other side.

[0030] First, the first vertical orientation will be described. As shown in Figure 1, when adjusting the height of the installed equipment 9, the laser oscillator 2 is placed in the first vertical orientation, and the laser oscillator 2 is installed on the installation surface via the laser oscillator stand 3. In the first vertical orientation, the first direction A and the second direction B are located in the horizontal plane, and the third direction C is located in the vertical plane, and the laser oscillator 2 can be adjusted horizontally to the installation surface by turning the first adjustment screw 3b. As shown in Figure 4, in the first vertical orientation, the first direction A coincides with the first horizontal direction a, the second direction B coincides with the second horizontal direction b, and the third direction C coincides with the vertical direction c.

[0031] The first support portion 3a is positioned to extend in a first horizontal direction a and a second horizontal direction b. The laser oscillator 2 is positioned on the upper surface of the first support portion 3a. The first adjustment screw 3b is positioned to be in contact with the mounting surface and serves to adjust the laser oscillator 2 horizontally to the mounting surface. The second support portion 3c is positioned to extend vertically c from the first support portion 3a. The second adjustment screw 3d is positioned not to contact the mounting surface and does not contribute to adjusting the laser oscillator 2 horizontally to the mounting surface. The laser blocking arm 3e is rotatably attached to the second support portion 3c via a rotation axis 3r extending vertically c. When the laser blocking arm 3e is in the blocking position, it blocks the irradiation port of the rotating head 2b from the other side of the second horizontal direction b, and extends in the first horizontal direction a and vertical direction c, perpendicular to the second support portion 3c. When the laser blocking arm 3e is in the non-blocking position, it is away from the irradiation port of the rotating head 2b and extends in the second horizontal direction b and vertical direction c, parallel to the second support part 3c. The operating handle 3s is rotatable about the vertical direction c as its axis. By rotating the operating handle 3s and the operating screw part 3t, the position of the movable part 3k and the laser oscillator 2 in the vertical direction c can be adjusted. In the first vertical orientation, the laser oscillator 2 automatically levels itself horizontally.

[0032] Next, the first horizontal orientation will be described. When adjusting the tilt of the mounting equipment 9 shown in Figure 2, and when adjusting the relative positions of the two mounting equipment units 9 and 10 shown in Figure 3, the laser oscillator 2 is placed in the first horizontal orientation. However, when adjusting the tilt of the mounting equipment 9, the laser oscillator 2 is installed on the mounting surface via the laser oscillator stand 3. On the other hand, when adjusting the relative positions of the two mounting equipment units 9 and 10, the laser oscillator 2 is installed on the mounting equipment 10 via the laser oscillator stand 3. In the first horizontal orientation, the first direction A and the third direction C are located in the horizontal plane, and the second direction B is located in the vertical plane, and the laser oscillator 2 can be adjusted horizontally to the mounting surface by turning the second adjustment screw 3d. When adjusting the tilt of the mounting equipment 9, the laser oscillator 2 is adjusted horizontally to the mounting surface by turning the second adjustment screw 3d. On the other hand, when adjusting the relative positions of the two installation devices 9 and 10, the installation device 10 is sandwiched between the clamping screw 3i and the other clamping part 3h, thereby installing the laser oscillator stand 3, to which the laser oscillator 2 is attached, onto the installation device 10. As shown in Figures 5 and 6, in the first horizontal position, the first direction A coincides with the first horizontal direction a, the third direction C coincides with the second horizontal direction b, and the second direction B coincides with the vertical direction c.

[0033] As shown in Figure 5, the first support portion 3a is positioned to extend in the first horizontal direction a and the vertical direction c. The laser oscillator 2 is positioned on the side of the first support portion 3a. The first adjustment screw 3b is positioned not in contact with the mounting surface and does not contribute to adjusting the laser oscillator 2 horizontally to the mounting surface. The second support portion 3c is positioned to extend from the first support portion 3a in the second horizontal direction b. The second adjustment screw 3d is positioned to be in contact with the mounting surface and plays a role in adjusting the laser oscillator 2 horizontally to the mounting surface. The laser blocking arm 3e is rotatably attached to the second support portion 3c via a rotation axis 3r that extends in the second horizontal direction b. When the laser blocking arm 3e is in the blocking position, it blocks the irradiation port of the rotating head 2b from above in the vertical direction c and extends in the first horizontal direction a and the second horizontal direction b, perpendicular to the second support portion 3c. When the laser blocking arm 3e is in the non-blocking position, it is away from the irradiation port of the rotating head 2b and extends in the second horizontal direction b and the vertical direction c, parallel to the second support part 3c. The operating handle 3s is rotatable about the second horizontal direction b as its axis. By rotating the operating handle 3s and the operating screw part 3t, the positions of the movable part 3k and the laser oscillator 2 in the second horizontal direction b can be adjusted. The clamping screws 3i are rotatable about the second horizontal direction b as their axis. By rotating each clamping screw 3i, the clamping screws 3i can move closer to and further away from the other clamping part 3h in the second horizontal direction b. By bringing the clamping screws 3i closer to the other clamping part 3h in the second horizontal direction b, it is possible to clamp the installation equipment 10 between the clamping screws 3i and the other clamping part 3h, and the laser oscillator stand 3 can be attached to the installation equipment 10. On the other hand, by separating the clamping screw 3i in the second horizontal direction b from the other clamping part 3h, the laser oscillator stand 3 can be removed from the installed equipment 10. In the first horizontal position, the laser oscillator 2 automatically levels itself vertically.

[0034] As shown in Figures 1 to 3, the laser catcher 4 receives the laser 2a emitted from the laser oscillator 2. Figure 7 is a perspective view showing the laser catcher stand 5 that holds the laser catcher 4 in a second vertical position. As shown in Figure 7, the laser catcher 4 is formed in the shape of a rectangular parallelepiped. A laser receiving reference line 4a, a receiving sensor 4b, and a notification unit 4c are provided on the front of the laser catcher 4. The receiving sensor 4b detects the laser 2a. The notification unit 4c, in the illustrated example, includes three lamps 4d, a speaker 4e, and a display unit 4f. The display unit 4f is, for example, a liquid crystal panel. The receiving sensor 4b and the display unit 4f are arranged side by side in the short direction of the laser catcher 4. The laser receiving reference line 4a is a reference line that indicates the correct irradiation position of the laser 2a. The laser receiving reference line 4a extends in the short direction of the laser catcher 4. The laser light receiving reference line 4a is a discontinuous straight line that is interrupted by the light receiving sensor 4b and the display unit 4f.

[0035] The light receiving sensor 4b is electrically connected to the notification unit 4c. When the received laser 2a is on the laser receiving reference line 4a, the light receiving sensor 4b transmits a normal signal to the notification unit 4c indicating that there is no misalignment between the received laser 2a and the laser receiving reference line 4a. When the received laser 2a is not on the laser receiving reference line 4a, the light receiving sensor 4b transmits an abnormal signal to the notification unit 4c indicating that there is a misalignment between the received laser 2a and the laser receiving reference line 4a.

[0036] When the notification unit 4c receives an abnormal signal, it notifies the operator of the deviation (hereinafter sometimes referred to as "deviation") between the received laser 2a and the laser receiving reference line 4a, either visually or audibly. The three lamps 4d are arranged in a line perpendicular to the laser receiving reference line 4a (the longitudinal direction of the laser catcher 4). The central lamp 4d of the three lamps 4d is located on the extension of the laser receiving reference line 4a. When the notification unit 4c receives an abnormal signal, it notifies the operator visually, for example, by lighting up one of the lamps 4d located at the ends of the three lamps 4d in red, or audibly by emitting a sound from the speaker 4e. The notification unit 4c also displays the deviation numerically on the display unit 4f. This allows the operator to accurately grasp the magnitude of the deviation.

[0037] Furthermore, the notification unit 4c may also notify, visually and audibly, that there is no discrepancy between the received laser 2a and the laser reception reference line 4a when a normal signal is received. When the notification unit 4c receives a normal signal, it may, for example, visually notify by lighting the central lamp 4d of the three lamps 4d in green, or audibly notify by emitting a different sound from the speaker 4e than when an abnormal signal is received.

[0038] Next, with reference to Figures 1 to 3 and Figures 7 to 15, several types of laser catcher stands 5, 6, and 7 and riser blocks 8 will be described. Figure 8 is a perspective view showing a laser catcher stand 5 that holds a second vertically positioned laser catcher 4, viewed from a different angle than Figure 7. Figure 9 is a side view showing a riser block 8. Figure 10 is a perspective view showing a laser catcher stand 6 that holds a second horizontally positioned laser catcher 4. Figure 11 is a perspective view showing a laser catcher stand 6 that holds a second horizontally positioned laser catcher 4, viewed from a different angle than Figure 10. Figure 12 is a bottom view showing a laser catcher stand 6 that holds a second horizontally positioned laser catcher 4. Figure 13 is a perspective view showing another example of a laser catcher stand 7 that holds a second horizontally positioned laser catcher 4. Figure 14 is a perspective view showing another example of the laser catcher stand 7 that holds the laser catcher 4 in a second horizontal position, and is viewed from a different angle than Figure 13. Figure 15 is a bottom view showing another example of the laser catcher stand 7 that holds the laser catcher 4 in a second horizontal position.

[0039] The laser catcher stands 5, 6, and 7 are selected from a laser catcher stand 5 that holds the laser catcher 4 in a second vertical position where the laser receiving reference line 4a, described later, is located in the horizontal plane, and another laser catcher stand 6 or 7 that holds the laser catcher 4 in a second horizontal position where the laser receiving reference line 4a is located in the vertical plane.

[0040] As shown in Figure 1, the laser catcher stand 5 is a stand for attaching the laser catcher 4 to the installation equipment 9. The laser catcher stand 5 is used when adjusting the height of the installation equipment 9. When adjusting the height of the installation equipment 9, the laser catcher 4 is set to a second vertical position where the laser receiving reference line 4a is located in the horizontal plane. When adjusting the height of the installation equipment 9, the laser catcher 4 is installed on the installation equipment 9 via the laser catcher stand 5. By using the laser catcher stand 5, it becomes possible to check how much the laser 2a irradiated in the horizontal plane deviates from the laser receiving reference line 4a.

[0041] As shown in Figures 7 and 8, the laser catcher stand 5 comprises a base 5a, a holding part 5b, a height adjustment mechanism 5c, a slide rail 5d, and a magnetic block 5e.

[0042] The base portion 5a is attached to the installation equipment 9 via a riser block 8, which will be described later, and is a plate-shaped portion that extends in the vertical direction c and the second horizontal direction b. As shown in Figure 8, a slide hole 5f is formed in the base portion 5a that penetrates in the first horizontal direction a. A cylindrical block mounting portion 5g is formed in the portion of the base portion 5a below the slide hole 5f. The block mounting portion 5g protrudes in the other direction of the first horizontal direction a, opposite to the holding portion 5b. In this embodiment, there are two block mounting portions 5g, but this may be changed as appropriate. The two block mounting portions 5g are spaced apart from each other in the second horizontal direction b.

[0043] The holding portion 5b is a plate-shaped part to which the laser catcher 4 is attached, extending vertically c and in a second horizontal direction b between the laser catcher 4 and the base portion 5a. The laser catcher 4 is attached to the portion of the holding portion 5b that faces away from the base portion 5a. The laser catcher 4 and the laser catcher stand 5 are fixed together with screws (not shown). Specifically, the laser catcher 4 and the laser catcher stand 5 are fixed together by screwing screws attached to the holding portion 5b of the laser catcher stand 5 into screw holes (not shown) formed in the laser catcher 4. As shown in Figure 7, the holding portion 5b is provided with a stand-side reference line 5h located in the horizontal plane. The stand-side reference line 5h is a straight reference line for positioning the laser catcher 4 on the laser catcher stand 5. By aligning the reference line 5h on the mounting base with the laser receiving reference line 4a in the vertical direction c, the laser catcher 4 can be positioned on the mounting base 5 for the laser catcher.

[0044] The height adjustment mechanism 5c is a mechanism that can adjust the height of the holding part 5b and the laser catcher 4 in the vertical direction c. The height adjustment mechanism 5c has a height adjustment operating part 5i and a screw part 5j. The height adjustment operating part 5i is rotatably mounted on the base 5a about the vertical direction c as an axis. The height adjustment operating part 5i includes an operating handle 5k and an operating screw part 5m. The height adjustment operating part 5i is mounted near the upper end of the base 5a via a connecting member 5n. The shape of the operating handle 5k is cylindrical. The operating handle 5k is positioned above the upper end of the base 5a. The upper end of the operating screw part 5m is fitted inside the operating handle 5k. The operating screw part 5m rotates with the rotation of the operating handle 5k. The operating screw part 5m is positioned between the base 5a and the holding part 5b in the first horizontal direction a. The operating screw part 5m extends downward from the operating handle 5k. The lower end of the operating screw portion 5m is attached to the retaining portion 5b via the threaded portion 5j.

[0045] The threaded portion 5j is a plate-shaped portion attached to the part of the holding portion 5b that faces the base portion 5a, and into which the operating screw portion 5m is screwed. The threaded portion 5j extends from the part of the holding portion 5b that faces the base portion 5a to the other side in the first horizontal direction a, and is located within the slide hole 5f. A screw hole is formed in the threaded portion 5j into which the operating screw portion 5m is screwed. By rotating the operating handle 5k around the vertical direction c as an axis and thereby rotating the operating screw portion 5m, the height of the threaded portion 5j, the holding portion 5b, and the laser catcher 4 in the vertical direction c can be adjusted.

[0046] As shown in Figure 8, the slide rail 5d is attached to the base 5a and guides the movement of the retaining part 5b in the vertical direction c. The slide rail 5d is attached to the portion of the base 5a that faces the retaining part 5b. The slide rail 5d extends in the vertical direction c.

[0047] The magnetic block 5e is an adsorption member attached to the base 5a. The magnetic block 5e is attached by magnetic force to the riser block 8 placed on the bottom surface of the installation equipment 9. The magnetic block 5e has a rectangular outer shape and a cylindrical inner shape. The magnetic block 5e is attached to the base 5a by inserting the block mounting part 5g into the inside of the magnetic block 5e. The laser catcher stand 5 is fixed to the riser block 8 by the magnetic force of the magnetic block 5e.

[0048] As shown in Figure 9, the raising block 8 is a component for raising the laser catcher 4 and the laser catcher stand 5. The raising block 8 has a leg portion 8a, a mounting portion 8b, and a height adjustment screw 8c. The leg portion 8a extends in the vertical direction c. The mounting portion 8b is a flat portion that extends in a second horizontal direction b from the upper end of the leg portion 8a. The height adjustment screw 8c is positioned away from the leg portion 8a in the second horizontal direction b. The height adjustment screw 8c penetrates the mounting portion 8b in the vertical direction c. The height adjustment screw 8c is rotatably mounted on the mounting portion 8b with the vertical direction c as its axis. By rotating the height adjustment screw 8c, the position of the height adjustment screw 8c in the vertical direction c relative to the leg portion 8a can be adjusted. In this way, the raising block 8 can be adjusted horizontally even if there is a step between the bottom surface of the installed equipment 9 and the surrounding mounting surface.

[0049] As shown in Figures 2 and 3, the laser catcher stands 6 and 7 are both stands for attaching the laser catcher 4 to the installation equipment 9. When adjusting the tilt of the installation equipment 9 or adjusting the relative positions of the two installation equipment units 9 and 10, use either the laser catcher stand 6 or the laser catcher stand 7. When adjusting the tilt of the installation equipment 9 or adjusting the relative positions of the two installation equipment units 9 and 10, set the laser catcher 4 to a second horizontal position where the laser receiving reference line 4a is located in the vertical plane. When adjusting the tilt of the installation equipment 9 or adjusting the relative positions of the two installation equipment units 9 and 10, install the laser catcher 4 on the installation equipment 9 via the laser catcher stand 6 or the laser catcher stand 7. By using the laser catcher stands 6 and 7, it becomes possible to check how much the laser 2a irradiated in the vertical plane deviates from the laser receiving reference line 4a.

[0050] As shown in Figure 10, the laser catcher stand 6 comprises a base 6a, a holding part 6b, a pair of clamping parts 6c and 6d, and a clamping screw 6e. The base 6a is attached to the installation equipment 9 and is a plate-shaped portion extending in the vertical direction c and a second horizontal direction b. The shape of the base 6a is a rectangle that is longer in the second horizontal direction b than in the vertical direction c.

[0051] The holding portion 6b is a plate-shaped part to which the laser catcher 4 is attached, extending from the base portion 6a in the first horizontal direction a. The holding portion 6b extends from the lower end of the base portion 6a toward one side of the first horizontal direction a. The laser catcher 4 is positioned on top of the holding portion 6b. As shown in Figure 12, the holding portion 6b has a holding plate 6f, a movable plate 6g, and a position adjustment mechanism 6h. The holding plate 6f is immovably attached to the base portion 6a. The holding plate 6f is a plate-shaped part extending from the lower end of the base portion 6a in the first horizontal direction a and the second horizontal direction b. The movable plate 6g is a plate-shaped part positioned on top of the holding plate 6f and movable in the second horizontal direction b. The laser catcher 4 is fixed on top of the movable plate 6g. The length of the movable plate 6g in the second horizontal direction b is shorter than the length of the holding plate 6f in the second horizontal direction b.

[0052] The retaining plate 6f has an oval-shaped slot 6i extending in the second horizontal direction b. The movable plate 6g is fitted with a position adjustment screw 6j that is inserted into the slot 6i. The position adjustment mechanism 6h includes the movable plate 6g, the slot 6i, and the position adjustment screw 6j, and is a mechanism that can adjust the position of the laser catcher 4 in the second horizontal direction b. By changing the position of the position adjustment screw 6j in the slot 6i, the positions of the movable plate 6g and the laser catcher 4 in the second horizontal direction b can be adjusted. The position adjustment screw 6j also plays a role in fixing the laser catcher 4 and the laser catcher stand 6. Specifically, the laser catcher 4 and the laser catcher stand 6 are fixed together by screwing the position adjustment screw 6j, which is attached to the movable plate 6g of the laser catcher stand 6, into a screw hole (not shown) formed in the laser catcher 4. As shown in Figures 10 and 12, the movable plate 6g is provided with a frame-side reference line 6k located in the vertical and horizontal planes. The positional relationship between the laser receiving reference line 4a shown in Figure 10 and the frame-side reference line 6k of the movable plate 6g is uniquely determined by screw holes (not shown). As shown in Figure 12, the holding plate 6f is provided with a frame-side reference line 6n located in the horizontal plane. The frame-side reference line 6k of the movable plate 6g and the frame-side reference line 6n of the holding plate 6f are linear reference lines for positioning the laser catcher 4 on the laser catcher frame 6. By aligning the frame-side reference line 6k of the movable plate 6g and the frame-side reference line 6n of the holding plate 6f in the horizontal plane, the laser catcher 4 can be positioned on the laser catcher frame 6.

[0053] The pair of clamping portions 6c and 6d extend from the base portion 6a toward the opposite side of the holding portion 6b in the first horizontal direction a, and are spaced apart from each other in the second horizontal direction b. One clamping portion 6c is provided at one end of the base portion 6a in the second horizontal direction b. The clamping portion 6c is a plate-like portion that extends in the first horizontal direction a and the vertical direction c. The other clamping portion 6d is provided at the other end of the base portion 6a in the second horizontal direction b. The clamping portion 6d is a plate-like portion that extends in the first direction A and the vertical direction c.

[0054] The clamping screw 6e is a screw that is rotatably attached to one of the clamping parts 6c around a second horizontal direction b. In this embodiment, one clamping screw 6e is attached to one of the clamping parts 6c. The clamping screw 6e penetrates one of the clamping parts 6c in the second horizontal direction b. By rotating the clamping screw 6e around the second horizontal direction b, the clamping screw 6e can move closer to and further away from the other clamping part 6d. By moving the clamping screw 6e closer to the other clamping part 6d in the second horizontal direction b, it is possible to clamp the installation equipment 9 between the clamping screw 6e and the other clamping part 6d, and the laser catcher stand 6 can be attached to the installation equipment 9. On the other hand, by moving the clamping screw 6e away from the other clamping part 6d in the second horizontal direction b, the laser catcher stand 6 can be removed from the installation equipment 9.

[0055] As shown in Figure 11, a plate-shaped cushioning material 6m is attached to the portion of the base 6a facing the equipment 9. A plate-shaped cushioning material 6m is also attached to the portion of the clamping portion 6d facing the equipment 9, and a cylindrical cushioning material 6m is attached to the portion of the clamping screw 6e facing the equipment 9. The cushioning material 6m plays a role in suppressing damage to the equipment 9 caused by contact between the equipment 9 and the laser catcher stand 6. The cushioning material 6m is, for example, monomer-cast nylon pad.

[0056] As shown in Figure 13, the laser catcher stand 7 comprises a base 7a, a holding part 7b, and a handle 7c. While the laser catcher stand 6 described above was mechanically attached to the installation equipment 9 using a pair of clamping parts 6c, 6d and clamping screws 6e, the laser catcher stand 7 is manually attached to the installation equipment 9 by an operator using the handle 7c.

[0057] The configuration of the base 7a, holding part 7b, holding plate 7d, movable plate 7e, position adjustment mechanism 7f, elongated hole 7g, and position adjustment screw 7h is the same as the base 6a, holding part 6b, holding plate 6f, movable plate 6g, position adjustment mechanism 6h, elongated hole 6i, and position adjustment screw 6j of the laser catcher stand 6 described above, so its explanation is omitted here. The laser catcher 4 and the laser catcher stand 7 are fixed together by screwing the position adjustment screw 7h attached to the movable plate 7e of the laser catcher stand 7 into a screw hole (not shown) formed in the laser catcher 4. As shown in Figures 13 and 15, the movable plate 7e is provided with a stand-side reference line 7i located in the vertical plane and the horizontal plane. The positional relationship between the laser receiving reference line 4a shown in Figure 13 and the stand-side reference line 7i of the movable plate 7e is uniquely determined by a screw hole (not shown). As shown in Figure 15, the holding plate 7d is provided with a frame-side reference line 7m located in the horizontal plane. The frame-side reference line 7i of the movable plate 7e and the frame-side reference line 7m of the holding plate 7d are straight reference lines for positioning the laser catcher 4 on the laser catcher frame 7. By aligning the frame-side reference line 7i of the movable plate 7e and the frame-side reference line 7m of the holding plate 7d in the horizontal plane, the laser catcher 4 can be positioned on the laser catcher frame 7.

[0058] As shown in Figure 14, the base 7a has a handle support portion 7j. The handle support portion 7j extends from the base 7a in a first horizontal direction a away from the holding portion 7b. The handle support portion 7j is provided at the other end of the base 7a in a second horizontal direction b. The handle support portion 7j is a plate-like portion extending in the first horizontal direction a and the vertical direction c.

[0059] The handle 7c is attached to the handle support portion 7j of the base portion 7a and is a portion in which an opening is formed that penetrates in the first horizontal direction a. To adjust the position of the laser catcher 4 in the vertical direction c, the operator can grasp the handle 7c and move the laser catcher stand 7 to which the laser catcher 4 is attached along the height direction of the installed equipment 9.

[0060] A plate-shaped cushioning material 7k is attached to the part of the base 7a that faces the installed equipment 9. Similarly, a plate-shaped cushioning material 7k is attached to the part of the handle support 7j that faces the installed equipment 9. The cushioning material 7k plays a role in suppressing damage to the installed equipment 9 caused by contact between the installed equipment 9 and the laser catcher stand 7. The cushioning material 7k is, for example, a monomer-cast nylon pad.

[0061] Next, with reference to Figures 1 to 3 and Figure 16, the installation method for the installation equipment 9 and 10 according to this embodiment will be described. Figure 16 is a plan view showing the state in which two installation devices 9 and 10 are installed on a road 11. Specifically, the road 11 is an ETC lane. Figure 16 illustrates a car 12 traveling on the road 11. The installation method for the installation equipment 9 and 10 is a method for installing the installation equipment 9 on the installation surface during ETC construction, and includes an installation step for the laser oscillator 2, an installation step for the laser catcher 4, an irradiation step, and an adjustment step. Below, an overview of each step will be described, followed by a detailed description of each step when performing each of the three adjustment tasks.

[0062] The installation process for the laser oscillator 2 involves changing the orientation of the laser oscillator stand 3 on which the laser oscillator 2 is mounted, so that the laser oscillator 2 is in a first vertical or first horizontal position, and then installing the laser oscillator 2 on the mounting equipment 10 or on the mounting surface via the laser oscillator stand 3.

[0063] The installation process for the laser catcher 4 involves selecting one of several types of laser catcher stands 5, 6, or 7. The installation process for the laser catcher 4 also involves using the selected laser catcher stand 5, 6, or 7 to hold the laser catcher 4 in a second vertical or second horizontal position, and then installing the laser catcher 4 on the mounting equipment 9 via the laser catcher stand 5, 6, or 7. In this embodiment, the installation process for the laser catcher 4 is performed after the installation process for the laser oscillator 2, but it may also be performed before or simultaneously with the installation process for the laser oscillator 2.

[0064] The irradiation process involves irradiating the laser catcher 4 with laser 2a from the laser oscillator 2.

[0065] The adjustment process involves adjusting the height of the installed equipment 9, the tilt of the installed equipment 9, and the relative positions of the two installed equipment 9 and 10, while visually and audibly confirming the discrepancy between the received laser 2a and the laser receiving reference line 4a. In this embodiment, the operator visually and audibly confirms the discrepancy using the color of the lamp 4d, the sound emitted from the speaker 4e, and the numerical value displayed on the display unit 4f.

[0066] Next, we will explain the details of each step involved in adjusting the height of the installed equipment 9.

[0067] As shown in Figure 1, in the installation process of the laser oscillator 2, the laser oscillator 2 is placed in a first vertical position, and the laser oscillator stand 3 is installed on the installation surface. In the installation process of the laser oscillator 2, the laser oscillator stand 3 with the laser oscillator 2 attached is installed at a height reference position (for example, the center in the width direction of the road). In the installation process of the laser oscillator 2, the laser oscillator 2 is roughly adjusted to be horizontal on the installation surface by turning the first adjustment screw 3b. In the installation process of the laser oscillator 2, the position of the laser oscillator 2 in the vertical direction c is adjusted by turning the operating handle 3s to rotate the operating screw part 3t.

[0068] In the installation process for the laser catcher 4, the laser catcher 4 is held in a second vertical position by the laser catcher stand 5, and then the laser catcher stand 5 is installed on the mounting equipment 9. In the installation process for the laser catcher 4, the laser catcher 4 is attached to the laser catcher stand 5 with the laser receiving reference line 4a and the stand-side reference line 5h aligned (see Figure 7). In the installation process for the laser catcher 4, the laser catcher stand 5 is installed on the mounting equipment 9 via the riser block 8. In the installation process for the laser catcher 4, the riser block 8 is placed across the bottom surface of the mounting equipment 9 and the surrounding mounting surfaces, and then the riser block 8 is adjusted to be horizontal by rotating the height adjustment screw 8c. After that, the laser catcher stand 5 is placed on top of the riser block 8.

[0069] In the irradiation process, the laser 2a is irradiated from the laser oscillator 2 onto the laser catcher 4 in a horizontal plane. In the irradiation process, the power to the laser oscillator 2 and the laser catcher 4 is turned on, and the laser 2a is irradiated after the laser oscillator 2 has automatically completed the leveling process.

[0070] In the adjustment process, the height of the installed equipment 9 is adjusted while visually and audibly confirming the vertical deviation c between the received laser 2a and the laser receiving reference line 4a. In this embodiment, the deviation between the received laser 2a and the laser receiving reference line 4a is displayed numerically on the laser catcher 4, so in the adjustment process, the height of the installed equipment 9 can be adjusted while visually confirming the numerical value displayed on the laser catcher 4. In the adjustment process, the height of the installed equipment 9 is adjusted until the deviation is eliminated.

[0071] Next, we will explain the details of each step involved in adjusting the tilt of the installed equipment 9.

[0072] As shown in Figure 2, in the installation process of the laser oscillator 2, the laser oscillator 2 is placed in the first horizontal position, and then the laser oscillator stand 3 is installed on the installation surface. In the installation process of the laser oscillator 2, the laser oscillator stand 3 with the laser oscillator 2 attached is installed on a flat installation surface adjacent to the installation equipment 9. In the installation process of the laser oscillator 2, the laser oscillator 2 is roughly adjusted to be horizontal on the installation surface by turning the second adjustment screw 3d.

[0073] In the installation process of the laser catcher 4, the laser catcher 4 is held in a second horizontal position using the laser catcher stand 6 or the laser catcher stand 7, and then the laser catcher stand 6 or the laser catcher stand 7 is installed on the mounting equipment 9. In the illustrated example, the laser catcher stand 6 is used. When using the laser catcher stand 6, the mounting equipment 9 can be clamped between the clamping part 6d and the clamping screw 6e, and the laser catcher stand 6 can be mechanically fixed to the mounting equipment 9.

[0074] In the irradiation process, the laser 2a is irradiated from the laser oscillator 2 onto the laser catcher 4 in a vertical plane. In the irradiation process, the power to the laser oscillator 2 and the laser catcher 4 is turned on, and the laser 2a is irradiated after the laser oscillator 2 has automatically completed the leveling process.

[0075] In the adjustment process, the horizontal (second horizontal direction b) deviation between the received laser 2a and the laser receiving reference line 4a is confirmed visually and audibly at least one of two locations in the vertical direction c. The tilt of the installed equipment 9 is measured from the difference in the deviations at the two locations, and the tilt of the installed equipment 9 is adjusted. In the adjustment process, the numerical value displayed on the laser catcher 4 can be visually confirmed at two locations in the vertical direction c, and the tilt of the installed equipment 9 can be measured from the difference in the numerical value at the two locations, and the tilt of the installed equipment 9 can be adjusted. In the installation process of the laser catcher 4, as shown in the illustrated example, one laser catcher 4 and one laser catcher stand 6 may be installed at two locations separated from each other in the vertical direction c, and the deviation between the two locations may be confirmed in one step. Alternatively, in the installation process for the laser catcher 4, one laser catcher 4 and one laser catcher stand 6 may be installed at each location, and after confirming the misalignment at one location, the positions of the laser catcher 4 and the laser catcher stand 6 in the vertical direction c may be changed to confirm the misalignment at another location. In other words, the misalignment at two locations may be confirmed in two separate steps.

[0076] Next, we will describe the details of each step in the process of adjusting the relative positions of the two installation devices 9 and 10. As shown in Figure 16, the process of adjusting the relative positions of the two installation devices 9 and 10 is the process of adjusting them so that they are in the same position in the direction of travel of the road 11.

[0077] As shown in Figure 3, in the installation process of the laser oscillator 2, the laser oscillator 2 is placed in a first horizontal position, and the laser oscillator stand 3 is installed on one of the mounting equipment 10. In the installation process of the laser oscillator 2, the mounting equipment 10 is clamped between the clamping part 3h and the clamping screw 3i, and the laser oscillator stand 3 is mechanically fixed to the mounting equipment 10. In the installation process of the laser oscillator 2, the laser oscillator stand 3 is attached to the part of the mounting equipment 10 that faces the road 11. In the illustrated example, the first horizontal direction a coincides with the width direction of the road 11, and the second horizontal direction b coincides with the direction of travel of the road 11.

[0078] In the installation process for the laser catcher 4, the laser catcher 4 is held in a second horizontal position using the laser catcher stand 6 or the laser catcher stand 7, and then the laser catcher stand 6 or the laser catcher stand 7 is installed on the other installation equipment 9. In the illustrated example, the laser catcher stand 7 is used. When using the laser catcher stand 7, the worker can hold and support the laser catcher stand 7 and manually fix it to the installation equipment 9.

[0079] In the irradiation process, the laser 2a is irradiated from the laser oscillator 2 onto the laser catcher 4 in a vertical plane. In the irradiation process, the power to the laser oscillator 2 and the laser catcher 4 is turned on, and the laser 2a is irradiated after the laser oscillator 2 has automatically completed leveling. In the irradiation process, the position of the laser oscillator 2 in the second horizontal direction b is adjusted by turning the operating handle 3s (see Figure 6) to rotate the operating screw part 3t (see Figure 6) so that the laser 2a passes through the center of the installation equipment 10 to which the laser oscillator 2 is attached (the center of the installation equipment 10 in the direction of travel of the road 11).

[0080] In the adjustment process, the relative positions of the two installation devices 9 and 10 are adjusted while visually and audibly confirming the horizontal misalignment (second horizontal direction b, direction of travel of the road 11) between the received laser 2a and the laser receiving reference line 4a. In the adjustment process, the relative positions of the two installation devices 9 and 10 can be adjusted while visually confirming the numerical value displayed on the laser catcher 4. In the adjustment process, the relative positions of the two installation devices 9 and 10 are adjusted by moving one or both of the two installation devices 9 and 10 in the direction of travel of the road 11 until the misalignment is eliminated.

[0081] Next, the effects of Embodiment 1 will be described.

[0082] In this embodiment, as shown in Figures 1 to 3, the installation equipment 9 is installed using a surveying system 1 comprising a laser oscillator 2, a laser oscillator stand 3, a laser catcher 4, and multiple types of laser catcher stands 5, 6, and 7. The laser oscillator stand 3 is a stand for mounting the laser oscillator 2 to the installation equipment 10 or the installation surface, and the state of the laser oscillator 2 can be changed between a first vertical orientation where the laser 2a is irradiated in a horizontal plane and a first horizontal orientation where the laser 2a is irradiated in a vertical plane. As a result, by simply changing the orientation of the laser oscillator stand 3 and changing the state of the laser oscillator 2 to the first vertical orientation or the first horizontal orientation, the same laser oscillator 2 and laser oscillator stand 3 can be used for all three adjustment operations. Therefore, it is not necessary to prepare a laser oscillator 2 and a laser oscillator stand 3 for each of the three adjustment operations.

[0083] In this embodiment, the multiple types of laser catcher mounts 5, 6, and 7 are mounts for attaching the laser catcher 4 to the installation equipment 9. The laser catcher mounts 5, 6, and 7 to be used are selected from a laser catcher mount 5 that holds the laser catcher 4 in a second vertical position where the laser receiving reference line 4a is located in the horizontal plane, and another laser catcher mount 6 and 7 that holds the laser catcher 4 in a second horizontal position where the laser receiving reference line 4a is located in the vertical plane. As a result, by selecting one type of laser catcher mount 5, 6, or 7 from the multiple types of laser catcher mounts 5, 6, or 7 and using the selected laser catcher mount 5, 6, or 7 to hold the laser catcher 4 in either the second vertical or second horizontal position, the same laser catcher 4 can be used for all three adjustment operations. Therefore, it is not necessary to prepare a separate laser catcher 4 for each of the three adjustment operations. On the other hand, the laser catcher stand 5 can be used for adjusting the height of the installed equipment 9, and either the laser catcher stand 6 or 7 can be used for adjusting the tilt of the installed equipment 9 and the relative positions of the two installed equipment units 9 and 10. Therefore, when performing the three adjustment operations, it is sufficient to prepare at least two types of laser catcher stands 5, 6, and 7, eliminating the need to prepare a different laser catcher stand 5, 6, and 7 for each of the three adjustment operations. Thus, in this embodiment, some of the equipment used in multiple adjustment operations can be standardized, reducing the time and effort required to prepare the equipment.

[0084] ETC installation requires road closures, necessitating the completion of three adjustment tasks quickly and efficiently.
