Description

[Technical field]

[0001] The present disclosure relates to a measuring instrument holder used when measuring the distance to facilities installed around an orbit (hereinafter referred to as peripheral facilities) using a laser measuring instrument. [Background technology]

[0002] For example, in the non-contact type measuring device described in Patent Document 1, a laser measuring instrument is placed on a cart that is suspended across two rails. The non-contact type measuring device calculates the vertical distance and horizontal distance to the surrounding equipment using the distance to the surrounding equipment measured by the laser measuring instrument.

[0003] The vertical distance is the vertical distance from the horizontal plane where the laser measuring instrument is located (hereinafter referred to as the reference horizontal plane) to the surrounding equipment. The horizontal distance is the distance between the position where the laser measuring instrument is located and the foot of a perpendicular line drawn from the surrounding equipment to the reference horizontal plane.

[0004] Incidentally, in the non-contact measuring device described in Patent Document 1, the laser measuring instrument is placed in the center of the width of the carriage, that is, in a position corresponding to the center between the two rails, so the vertical distance and the horizontal distance are distances based on this center position.

[0005] [Patent Document 1] JP 2013-134164 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the non-contact measuring device described in Patent Document 1, the laser measuring instrument is arranged on a cart, so the mass and size of the non-contact measuring device become large, and there are problems in terms of portability of the measuring device and operability during measurement work. The present disclosure discloses an example of a measuring instrument holder that takes this into consideration. [Means for solving the problem]

[0007] It is desirable for a measuring instrument holder used when measuring the distance to equipment installed around the orbit using a laser measuring instrument (11) to have at least one of the following configuration requirements, for example.

[0008] That is, the constituent feature is a clamp portion (3) that is fixed to a rail (R) so as to clamp the head (R1) of the rail (R) from the width direction, and is configured in a U-shape or C-shape having a first portion (31) that can contact an upper surface of the head (R1), a second portion (32) that extends from one end of the first portion (31) in a direction perpendicular to the first portion (31), and a third portion (33) that extends from the other end of the first portion (31) in a direction perpendicular to the first portion (31). the clamp section (3) provided in the third section (33) and displaceable between a position where it can contact a side surface of the head and a position where it cannot contact the side surface, the pressing section (5) cooperating with the second section (32) to clamp the head; a mounting table (7) on which a laser measuring instrument (11) can be placed; and a hinge section (9) which swingably connects the mounting table (7) to the clamp section (3), the hinge section (9) having a swing center axis (Lo) located on the second section (32) side.

[0009] This allows a user of the measuring instrument holder, i.e., an operator who uses the measuring instrument holder to measure vertical and horizontal distances to surrounding equipment, to measure vertical and horizontal distances by fixing the clamp portion (3) to one of the two rails, placing the laser measuring instrument (11) on the mounting table (7), and adjusting the elevation angle of the mounting table (7) so that the laser light is irradiated to the surrounding equipment.

[0010] Therefore, the measuring instrument holder has a smaller mass and size than the measuring device described in Patent Document 1, and therefore is more portable and easier to use during measurement operations than the measuring device described in Patent Document 1.

[0011] In addition, when fixing the clamp portion (3) to the rail, it is desirable for the worker to fix the clamp portion (3) to the rail with the first portion (31) horizontal, for example, by using a spirit level built into the laser measuring instrument (11).

[0012] This is because, when the first portion (31) is horizontal, the first portion (31) is approximately aligned with the reference horizontal plane, and therefore, when the laser measuring instrument (11) measures the distance, the distance between the measurement reference point set by the laser measuring instrument itself and the swing central axis (Lo) of the hinge portion (9) becomes small.

[0013] In addition, when measuring the construction gauge (especially the horizontal distance) using this measuring instrument holder, the measurement is not based on the center between the two rails, but on the inner wall intersection point between the first section (31) and the second section (32).

[0014] Incidentally, the symbols in the above parentheses are examples showing the correspondence with the specific configurations etc. described in the embodiments described below, and the present disclosure is not limited to the specific configurations etc. shown by the symbols in the above parentheses.

[0016] The following "embodiment of the invention" shows an example of an embodiment that falls within the technical scope of the present disclosure. In other words, the invention-specific matters described in the claims are not limited to the specific configurations and structures shown in the following embodiment.

[0017] In addition, arrows and diagonal lines indicating directions in each figure are provided to facilitate understanding of the relationship between the figures and the shapes of each member or part. Therefore, the invention shown in this disclosure is not limited to the directions indicated in each figure. Diagonal lines do not necessarily indicate cross-sectional views.

[0018] At least one of each of the components or parts described with a reference number is provided, unless otherwise specified by "one". In other words, unless otherwise specified by "one", two or more of the components may be provided. The measuring device holder shown in this disclosure includes at least one of the components such as the components or parts described with a reference number and the structural parts shown in the drawings.

[0019] (First embodiment) <1. Overview of the measuring instrument holder> This embodiment is a measuring instrument holder used when measuring the distance to surrounding facilities using a laser measuring instrument. The measuring instrument holder according to this embodiment is mainly used during measurement work to check whether surrounding facilities are within the structure gauge.

[0020] As shown in FIG. 1, the measuring device holder 1 includes at least a clamp portion 3, a pressing portion 5, a mounting base 7, a hinge portion 9, and the like. <Clamp section> The clamp portion 3 is a member configured in a U-shape or C-shape, and is fixed to the rail R by clamping the head R1 of the rail R from the width direction. Note that the width direction refers to the horizontal direction perpendicular to the longitudinal direction of the rail R.

[0021] Specifically, the clamp portion 3 has a first portion 31, a second portion 32, and a third portion 33. The first portion 31 is a plate-like portion capable of contacting an upper surface of the head R1. The second portion 32 is a plate-like portion extending from one end of the first portion 31 in a direction perpendicular to the first portion 31, as shown in FIG.

[0022] The third portion 33 is a plate-like portion extending from the other end of the first portion 31 in a direction perpendicular to the first portion 31. The clamp portion 3 according to this embodiment is an integral product in which the first portion 31 to the third portion 33 are integrally formed by pressing a steel plate.

[0023] 1, elastically deformable sheet materials 31A, 32A are provided on the inner surfaces of the first portion 31 and the second portion 32. The sheet material 31A is attached to the first portion 31. The sheet material 32A is attached to the second portion 32.

[0024] The sheet materials 31A and 32A according to this embodiment are made of rubber, hard urethane, etc. The inner surfaces of the first portion 31 and the second portion 32 refer to the portions of the first portion 31 and the second portion 32 that face the rail R when the clamp portion 3 is fixed to the rail R.

[0025] <Pressing part> 1, the pressing portion 5 is provided in the third region 33. The pressing portion 5 is displaceable between a position where it can contact the side surface of the head R1 (the left side of the head R1 in FIG. 1) and a position where it cannot contact the side surface.

[0026] The pressing portion 5 contacts the side surface of the head R1 (the left side of the head R1 in FIG. 1) to sandwich the head R1 in the width direction in cooperation with the second portion 32. Specifically, the pressing portion 5 has at least a male threaded rod 51, a contact portion 52, an elastic portion 53, etc.

[0027] The male threaded rod 51 is a rod-shaped male screw that is screwed into the female threaded hole 33A provided in the third portion 33 and passes through the female threaded hole 33A. The contact portion 52 is provided at the tip of the male threaded rod 51 on the second portion 32 side, and is a flange-shaped portion that can swing relative to the male threaded rod 51.

[0028] A handle 54 is provided at the tip of the male threaded rod 51 on the side opposite to the abutment portion 52. The handle 54 is a portion that is gripped when an operator operates the pressing portion 5. "Operating the pressing portion 5" refers to the act of rotating the male threaded rod 51 to displace the abutment portion 52.

[0029] The elastic portion 53 is an elastically deformable portion provided at a portion of the contact portion 52 that can come into contact with at least the rail R. Note that the elastic portion 53 according to this embodiment is made of a cover-like rubber that covers the contact portion 52.

[0030] <Placement table> The mounting table 7 is a portion on which the laser measuring instrument 11 is placed at least during measurement operation. The mounting table 7 is configured in an L-shape and has a first mounting plate 71 and a second mounting plate 72. The first mounting plate 71 is a plate-shaped portion facing the first portion 31.

[0031] The second mounting plate 72 is a plate-like portion extending from an end of the first mounting plate 71 in a direction perpendicular to the first mounting plate 71. The mounting table 7 according to this embodiment is an integrated product in which the first mounting plate 71 and the second mounting plate 72 are integrally formed by pressing a steel plate or the like.

[0032] The laser measuring instrument 11 is a non-contact measuring instrument that measures the distance to an object by irradiating the object with a laser beam. The laser measuring instrument 11 according to this embodiment can also detect the angle between the emitted laser beam and a horizontal plane.

[0033] <Hinge> The hinge portion 9 connects the mounting table 7 to the clamp portion 3 so as to be able to swing. The swing central axis Lo of the hinge portion 9 is located on the second portion 32 side. Specifically, the hinge portion 9 connects the second portion 32 of the clamp portion 3 and the second mounting plate 72 of the mounting table 7.

[0034] The hinge unit 9 has a mechanism capable of holding the mounting table 7 at any swing angle. Specifically, the hinge unit 9 according to this embodiment is configured as a torque hinge that utilizes frictional force. Note that the hinge unit 9 according to this embodiment is a torque hinge that is capable of adjusting the magnitude of the frictional force.

[0035] <2. Features of the measuring device holder according to this embodiment> An operator who uses the measuring instrument holder 1 of this embodiment to measure the vertical and horizontal distances to surrounding equipment can measure the vertical and horizontal distances by fixing the clamp portion 3 to one of the two rails R, placing the laser measuring instrument 11 on the mounting table 7, and adjusting the elevation angle of the mounting table 7 so that the laser light is irradiated to the surrounding equipment.

[0036] Therefore, the measuring instrument holder 1 has a smaller mass and size than the measuring instrument described in Patent Document 1, and therefore is more portable and easier to operate during measurement than the measuring instrument described in Patent Document 1.

[0037] When fixing the clamp unit 3 to the rail R, it is desirable to position the measuring instrument holder 1 so that the hinge unit 9 is located on the other rail side, that is, on the central side between the rails. When fixing the clamp unit 3 to the rail, it is desirable for an operator to fix the clamp unit 3 to the rail R with the first portion 31 horizontal, for example, by using a spirit level or the like built into the laser measuring instrument 11 (see FIG. 3).

[0038] This is because when the first part 31 is horizontal, the first part 31 is approximately aligned with the reference horizontal plane, and therefore when the laser measuring instrument 11 measures the distance, the distance between the measurement reference point set by the laser measuring instrument itself and the swing central axis Lo of the hinge part 9 becomes small.

[0039] In other words, when checking the construction gauge using the measuring instrument holder 1 of this embodiment, particularly when measuring the horizontal distance, the measurement is not based on the center between the two rails, but on the inner wall side intersection point between the first section 31 and the second section 32.

[0040] Elastically deformable sheet materials 31A, 32A are provided on the inner surfaces of the first portion 31 and the second portion 32. This makes it difficult for the position and posture of the measuring instrument holder 1 to shift when the clamp portion 3 is fixed to the head portion R1 of the rail R. As a result, the construction gauge can be properly confirmed.

[0041] An elastic portion 53 is provided at least at a portion of the abutment portion 52 that can come into contact with the rail R. This makes it even more difficult for the position and posture of the measuring instrument holder 1 to shift when the clamp portion 3 is fixed to the head portion R1 of the rail R.

[0042] The swing central axis Lo of the hinge portion 9 is located on the second portion 32 side. This prevents the distance between the measurement reference point of the laser measuring instrument and the swing central axis Lo from changing significantly even if the mounting angle of the laser measuring instrument 11, i.e., the swing angle of the mounting table 7, changes. As a result, the construction gauge can be appropriately confirmed.

[0043] The hinge section 9 has a mechanism that can hold the mounting table 7 at any swing angle. This allows the worker to easily change the mounting angle of the laser measuring instrument 11 to accommodate various peripheral equipment of different heights and sizes. This in turn makes it easier to check the construction gauge.

[0044] (Other embodiments) The sheet materials 31A and 32A according to the above-described embodiment are configured by the sheet material 31A attached to the first portion 31 and the sheet material 32A attached to the second portion 32. However, the present disclosure is not limited to this. That is, in the present disclosure, for example, the sheet materials 31A and 32A may be configured as a single continuous sheet material.

[0045] The handle 54 according to the embodiment described above rotates the male threaded rod 51. However, the present disclosure is not limited to this. That is, in the present disclosure, the handle may be configured by, for example, an operating lever that utilizes a cam.

[0046] In the above-described embodiment, the sheet materials 31A and 32A and the elastic portion 53 are provided. However, the present disclosure is not limited thereto. That is, the present disclosure may be configured such that, for example, at least one of the sheet materials 31A and 32A and the elastic portion 53 is eliminated.

[0047] In the above embodiment, when fixing the clamp unit 3 to the rail, the worker uses, for example, a spirit level or the like to fix the clamp unit 3 to the rail R in a state where the first portion 31 is horizontal. However, the present disclosure is not limited to this.

[0048] That is, when fixing the clamp portion 3 to the rail, for example, the first portion 31 may be in contact with the top of the head R1 and the second portion 32 may be in contact with the side of the head R1 (see FIG. 1) without being horizontal.

[0049] Furthermore, the present disclosure is not limited to the above-mentioned embodiments as long as it is consistent with the gist of the disclosure described in the above-mentioned embodiments. Therefore, the present disclosure may be a configuration in which at least two of the above-mentioned embodiments are combined, or a configuration in which any of the components illustrated or the components described with reference numerals in the above-mentioned embodiments are eliminated.
