Description

Technical Field

[0001] This invention belongs to the field of angle measurement technology, specifically relating to an angle measuring device and method for highway bridge and culvert construction. Background Technology

[0002] Highway bridges and culverts, including bridges and culverts, are constructed to allow vehicles to cross natural or man-made obstacles. Bridges are generally used to cross wider obstacles, such as rivers, canyons, and railways, and consist of piers, abutments, and a deck. Culverts, on the other hand, are smaller structures typically used to allow water or traffic to pass under highways.

[0003] During bridge and culvert construction, the angle, shape, and angle of the bridge and culvert vary depending on the terrain. Existing angle measuring devices for bridge and culvert construction are inconvenient to carry and have complex structures, making it impossible to measure the angle of measuring points located on non-horizontal surfaces, thus affecting the construction progress. Therefore, we propose an angle measuring device for highway bridge and culvert construction to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide an angle measurement structure that is simple in structure and reasonably designed in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] This invention provides an angle measuring device for highway bridge and culvert construction, comprising a base shell, a measuring mechanism, and an adjusting mechanism, wherein the adjusting mechanism is installed inside the base shell;

[0007] The measuring mechanism includes a disk, rotating columns, and reflecting mirrors. The disk is movably connected to the base shell, and angle scale lines are provided on the edge of the disk. There are two sets of reflecting mirrors and rotating columns. The two sets of reflecting mirrors are connected to the two sets of rotating columns and are perpendicular to the disk. One set of rotating columns is rotatably connected to the upper surface of the other set of rotating columns, and the other set of rotating columns is rotatably connected to the center of the top surface of the disk. A pointer is connected to both sets of rotating columns. The pointers point to the angle scale lines and are perpendicular to the reflecting mirrors. Laser emitters are provided on both sides of each set of reflecting mirrors. The laser emitters on one side are arranged vertically and vertically. The laser emitters emit lasers to the reflecting mirrors. Rotating the reflecting mirrors causes the lasers to irradiate the two sets of measuring points.

[0008] The disc is located at the adjustment end of the adjustment mechanism, which is used to adjust the disc so that it is parallel to the straight line formed by connecting the two sets of measurement points.

[0009] As a further optimization of the present invention, the adjustment mechanism includes two sets of semi-circular long plates arranged in a cross shape. Angle scale lines are opened on the surface of the two sets of long plates. A fixing plate is fixedly connected to the bottom of the base shell. Both ends of the two sets of long plates are rotatably connected to the surface of the fixing plate. Slide grooves are opened on the surface of the two sets of long plates. A movable rod is provided inside the base shell. One end of the movable rod is rotatably connected to the bottom of the base shell, and the other end passes through the two sets of slide grooves and is connected to the disc. A limiting mechanism is provided inside the base shell to limit the rotation of the long plates.

[0010] As a further optimization of the present invention, the limiting mechanism includes a trigger, a rotating ring, a fixing block, a fixing toothed plate, and a moving toothed plate. The rotating ring is rotatably connected to the inner wall of the base shell, and an arc-shaped groove is formed on the surface of the rotating ring. The trigger is fixedly connected to the surface of the rotating ring. A sliding groove is formed on the inner wall of the base shell, and a push rod is slidably connected in the sliding groove. One end of the push rod extends outside the sliding groove and is fixedly connected to the moving toothed plate. The fixing block is connected to the surface of the push rod located outside the sliding groove. The end of the fixing block away from the push rod passes through the arc-shaped groove. The moving toothed plate meshes with the fixing toothed plate. The fixing toothed plate is fixedly connected to the surface of the long plate and is located on the axis of rotation of the long plate. A tension spring is connected to the surface of the rotating ring, and the other end of the tension spring is connected to the inner wall of the base shell.

[0011] As a further optimization of the present invention, the movable rod includes a rotating frame and a connecting column. A fixed shaft is connected to the bottom of the base shell. A ring is rotatably sleeved on the surface of the fixed shaft near the upper end. The two ends of the rotating frame are rotatably connected to the surface of the ring. The connecting column is fixedly connected to the rotating frame. A slot is opened at the end of the connecting column away from the rotating frame. A plug is fixedly connected to the bottom surface of the disc. The plug is inserted into the slot. A fixing mechanism is provided on the connecting column to fix the plug in the slot.

[0012] As a further optimization of the present invention, the fixing mechanism includes a limiting ring, a sleeve, and a cylindrical block. The sleeve is slidably fitted onto the surface of the connecting column. A cylindrical groove is formed on the inner wall of the sleeve. The limiting ring is disposed in the cylindrical groove and fixedly fitted onto the surface of the connecting column. A compression spring is fixedly connected to the upper surface of the limiting ring. The other end of the compression spring is fixedly connected to the inner wall of the sleeve. A through hole is formed on the surface of the connecting column. A cylindrical block is slidably connected into the through hole. Both ends of the cylindrical block are arc-shaped. A limiting groove is formed on the surface of the connecting column at a position corresponding to the through hole. One end of the cylindrical block extends into the limiting groove. The upper end face of the sleeve is inclined.

[0013] As a further optimization of the present invention, the upper end face of the fixed shaft is provided with a insertion groove, and the insertion rod can be inserted into the insertion groove.

[0014] As a further optimization of the present invention, the upper end of the base shell is provided with a shell cover, and the base shell and the shell cover form a complete closed shell.

[0015] As a further optimization of the present invention, a level is installed on the base shell.

[0016] A method for measuring angles during highway bridge and culvert construction, applied to the aforementioned angle measuring device for highway bridge and culvert construction, includes the following steps:

[0017] S1. Place the device at the observation point, open the cover, and adjust the device to a horizontal position using a level.

[0018] S2. Rotate the trigger to make the push rod move the moving toothed plate away from the fixed toothed plate, so as to limit the mechanism's restriction on the long plate;

[0019] S3. Adjust the position of the disc by rotating the two sets of long plates, so that the disc is parallel to the straight line formed by connecting the two sets of measuring points. Then release the trigger to move the toothed plate and fix the position of the two sets of long plates.

[0020] S4. Turn on the laser emitter and rotate the two sets of reflective mirrors to direct the laser light onto the two sets of measurement points.

[0021] S5. Obtain the rotation angle of the two sets of reflecting mirrors by the direction of the pointer;

[0022] S6. Calculate the angle between the observation point and the two sets of measurement points using the principle of specular reflection of light.

[0023] The beneficial effects of this invention are as follows: This invention sets up a laser emitter to emit laser light onto a reflective lens. By rotating two sets of reflective lenses, the light is reflected to the measurement point. With the cooperation of the pointer and the angle scale, the angle of rotation of the reflective lens is obtained. Then, the angle between the observation point and the two sets of measurement points is calculated by the principle of specular reflection of light. The entire device has a simple structure and is convenient and practical. Attached Figure Description

[0032] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Example 1

[0034] refer to Figure 1 and Figure 2 The structure shown is an angle measuring device for highway bridge and culvert construction, including a base shell 1, a measuring mechanism 2 and an adjusting mechanism 3, with the adjusting mechanism 3 installed inside the base shell 1.

[0035] The measuring mechanism 2 includes a disk 21, a rotating column 22, and a reflecting mirror 23. The disk 21 is movably connected to the base shell 1. Angle scale lines are provided on the edge of the disk 21. Two sets of reflecting mirrors 23 and rotating columns 22 are provided. The two sets of reflecting mirrors 23 are connected to the two sets of rotating columns 22 and are perpendicular to the disk 21. One set of rotating columns 22 is rotatably connected to the upper surface of the other set of rotating columns 22. The other set of rotating columns 22 is rotatably connected to the center of the top surface of the disk 21. A pointer 24 is connected to both sets of rotating columns 22. The pointer 24 points to the angle scale lines and is perpendicular to the reflecting mirror 23. Laser emitters 25 are provided on both sides of each set of reflecting mirrors 23. The laser emitters 25 on one side are arranged vertically. The laser emitters 25 emit lasers to the reflecting mirrors 23. Rotating the reflecting mirrors 23 causes the lasers to irradiate the two sets of measuring points.

[0036] The disc 21 is located at the adjustment end of the adjustment mechanism 3. The adjustment mechanism 3 is used to adjust the disc 21 so that the disc 21 is parallel to the straight line formed by connecting the two sets of measurement points.

[0037] It should be noted that the laser emitters 25 on both sides of the reflector 23 are located on the 0° scale line and the 180° scale line respectively, and the initial position of the reflector 23 is on the same plane as the 0° scale line.

[0038] In practical use, the device is placed at the observation point, and two sets of laser emitters 25 on different horizontal lines are turned on as needed. The laser emitters 25 emit lasers onto the reflecting mirrors 23. Through the rotation of the two sets of reflecting mirrors 23, the light is reflected to the two sets of measurement points. With the cooperation of the pointer 24 and the angle scale, the angle of rotation of the reflecting mirrors 23 can be obtained. Then, the angle between the observation point and the two sets of measurement points can be calculated by the principle of specular reflection of light.

[0039] refer to Figure 1 and Figure 3 The structure shown includes an adjustment mechanism 3 comprising two sets of semi-circular long plates 31 arranged in a cross shape. Angle scale lines are provided on the surface of the two sets of long plates 31. A fixed plate 32 is fixedly connected to the bottom of the base shell 1. Both ends of the two sets of long plates 31 are rotatably connected to the surface of the fixed plate 32. Slide grooves 33 are provided on the surface of the two sets of long plates 31. A movable rod 4 is provided inside the base shell 1. One end of the movable rod 4 is rotatably connected to the bottom of the base shell 1, and the other end passes through the two sets of slide grooves 33 and is connected to the disc 21. A limiting mechanism 5 is provided inside the base shell 1 to limit the rotation of the long plates 31.

[0040] In this embodiment, the position of the disk 21 can be adjusted by setting the adjustment mechanism 3. With this setting, the device can still perform measurements even if the straight line formed by connecting two measurement points is not on the horizontal plane.

[0041] In other embodiments, the limiting mechanism 5 may be two sets of motors, but the use of motors would increase the manufacturing cost of the device. Therefore, this embodiment provides a limiting mechanism 5 that does not require the use of motors, thereby reducing the manufacturing cost.

[0042] Furthermore, the limiting mechanism 5 includes a trigger 51, a rotating ring 52, a fixing block 53, a fixing toothed plate 54, and a moving toothed plate 55. The rotating ring 52 is rotatably connected to the inner wall of the base shell 1. An arc-shaped groove 56 is formed on the surface of the rotating ring 52. The trigger 51 is fixedly connected to the surface of the rotating ring 52. A sliding groove is formed on the inner wall of the base shell 1. A push rod 57 is slidably connected in the sliding groove. One end of the push rod 57 extends out of the sliding groove and is fixedly connected to the moving toothed plate 55. The fixing block 53 is connected to the surface of the push rod 57 located outside the sliding groove. The end of the fixing block 53 away from the push rod 57 passes through the arc-shaped groove 56. The moving toothed plate 55 meshes with the fixing toothed plate 54. The fixing toothed plate 54 is fixedly connected to the surface of the long plate 31 and is located on the axis of rotation of the long plate 31. A tension spring 58 is connected to the surface of the rotating ring 52. The other end of the tension spring 58 is connected to the inner wall of the base shell 1.

[0043] It should be noted that at least one end of each of the two sets of long plates 31 is connected to a fixed toothed plate 54. In this embodiment, four sets of arc-shaped grooves 56 are provided, and therefore four sets of fixed toothed plates 54 and movable toothed plates 55 are also provided accordingly.

[0044] In actual use, the plate ring 52 is rotated by triggering the trigger 51. With the cooperation of the arc groove 56 and the fixed block 53, the push rod 57 will drive the moving toothed plate 55 away from the fixed toothed plate 54. Only then can the long plate 31 be rotated. After releasing the trigger 51, the moving toothed plate 55 will mesh with the fixed toothed plate 54 under the action of the tension spring 58, thereby restricting the rotation of the long plate 31.

[0045] refer to Figure 5 and Figure 6 The structure shown includes a movable rod 41 and a connecting post 42. A fixed shaft 43 is connected to the bottom of the base shell 1. A ring 44 is rotatably fitted on the surface of the fixed shaft 43 near the upper end. The two ends of the rotating frame 41 are rotatably connected to the surface of the ring 44. The connecting post 42 is fixedly connected to the rotating frame 41. A slot 7 is provided at the end of the connecting post 42 away from the rotating frame 41. An insert rod 8 is fixedly connected to the bottom surface of the disc 21. The insert rod 8 is inserted into the slot 7. A fixing mechanism 6 is provided on the connecting post 42 to fix the insert rod 8 in the slot 7.

[0046] Furthermore, the fixing mechanism 6 includes a limiting ring 61, a sleeve 62, and a cylindrical block 63. The sleeve 62 is slidably fitted onto the surface of the connecting post 42. A cylindrical groove 64 is formed on the inner wall of the sleeve 62. The limiting ring 61 is disposed in the cylindrical groove 64 and fixedly fitted onto the surface of the connecting post 42. A compression spring 65 is fixedly connected to the upper surface of the limiting ring 61. The other end of the compression spring 65 is fixedly connected to the inner wall of the sleeve 62. A through hole 66 is formed on the surface of the connecting post 42. A cylindrical block 63 is slidably connected in the through hole 66. Both ends of the cylindrical block 63 are arc-shaped. A limiting groove is formed on the surface of the connecting post 42 at the position corresponding to the through hole 66. One end of the cylindrical block 63 extends into the limiting groove. The upper end face of the sleeve 62 is inclined.

[0047] It should be noted that the openings on both sides of the through hole 66 are slightly smaller than the diameter of the cylindrical block 63, and the openings can only allow the part of the cylindrical block 63 with an arc surface to move out.

[0048] In actual use, the sleeve 62 is moved downward along the surface of the connecting post 42, so that the upper end of the sleeve 62 is away from the cylindrical block 63. Then the insertion rod 8 can be inserted into or pulled out of the slot 7. Under the force of the compression spring 65, the sleeve 62 is released, so that the sleeve 62 moves upward. Due to the inclined setting of the upper end surface of the sleeve 62, one end of the cylindrical block 63 is pressed into the limiting groove, thereby restricting the movement of the insertion rod 8.

[0049] Furthermore, the upper end face of the fixed shaft 43 is provided with a insertion groove 9, and the insertion rod 8 can be inserted into the insertion groove 9.

[0050] refer to Figure 4 and Figure 7 As shown in the partial structure, the upper end of the base shell 1 is provided with a shell cover 10, and the base shell 1 and the shell cover 10 form a complete closed shell.

[0051] It should be noted that after the measurement is completed, the disc 21 can be pulled out from the connecting post 42, then inserted into the insertion slot 9, and then the two sets of long plates 31 can be rotated so that the long plates 31 are located inside the base shell 1. Finally, the shell cover 10 is placed on the base shell 1, thus completing the storage of the entire device. Specifically, as shown... Figure 4 As shown.

[0052] Furthermore, a level 11 is installed on the base housing 1.

[0053] It should be noted that the device needs to be calibrated using a level 11 before use.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
