[0002] A centering instrument is a testing instrument used to detect and adjust the relative positional accuracy of connected equipment during installation, and to check whether the positions between equipment components are within design tolerances. Centering is generally divided into shaft centering, hole centering, and geometric centering.

[0003] In the field of engineering surveying, ensuring that multiple measuring instruments are in the same horizontal position in physical space is an important prerequisite for ensuring measurement accuracy. Currently, the common method is to keep the instruments on the same horizontal plane using a horizontal disk. However, in actual use, due to the complexity of engineering terrain, this method cannot meet the centering requirements in the vertical direction.

[0004] Therefore, it is necessary to invent a three-dimensional forced centering instrument to solve the above problems. Utility Model Content

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 5 The illustrated stereo forced centering instrument includes a support base 1, a fixed bracket 11 fixedly connected to the side of the support base 1, a photovoltaic panel 12 fixedly mounted on the side of the fixed bracket 11, a rotating plate 21 rotatably connected to the upper side of the support base 1, an equipment box 2 fixedly connected to the upper side of the rotating plate 21, and adjustment components provided on the inner and outer sides of the equipment box 2. The adjustment components include a servo motor 22, a first bevel gear 23, a support cylinder 3, a fixed bearing 31, a transmission shaft 32, a second bevel gear 33, a lifting cylinder 34, a positioning rod 35, a threaded sleeve 36, and a threaded rod 37. A positioning component is provided at the upper end of the lifting cylinder 34. The positioning component includes a mounting base 4, a horizontal disc 41, a first mounting column 42, a measuring device 43, a support frame 5, a second mounting column 51, and a satellite receiving module 52.

[0034] During use, photovoltaic panels 12 generate electricity, which is stored in the battery to power the equipment. After multiple sets of equipment are installed, the horizontal disc 41 is first adjusted to bring the multiple sets of measuring devices 43 to the same horizontal position. Satellite receiving module 52 is used to acquire satellite signals and calculate the height of the measuring devices 43. The measuring devices 43 in the multiple sets of equipment are vertically aligned. At this time, the height of the lifting cylinder 34 is adjusted by the cooperation of servo motor 22, first bevel gear 23, second bevel gear 33, transmission shaft 32, positioning rod 35, threaded sleeve 36 and threaded rod 37, thereby vertically aligning the multiple sets of measuring devices 43, improving the convenience of equipment adjustment and the alignment accuracy.

[0035] See Figure 1 and Figure 2 The mounting base 4 is fixedly connected to the middle of the upper end of the lifting cylinder 34. The horizontal disc 41 is installed on the upper side of the mounting base 4. The first mounting column 42 is fixed on the upper surface of the horizontal disc 41. The measuring device 43 is installed on the upper end of the first mounting column 42. The lower end of the support frame 5 is fixedly connected to the upper end of the lifting cylinder 34. The second mounting column 51 is fixedly installed on the upper end of the support frame 5. The satellite receiving module 52 is fixedly installed on the upper end of the second mounting column 51.

[0036] Specifically, during installation, the measuring device 43 is installed on the upper end of the first mounting post 42, and the satellite receiving module 52 is installed on the upper end of the second mounting post 51. The satellite receiving module 52 acquires satellite signals around the clock and calculates the precise position of the second mounting post 51. Since the distance between the second mounting post 51 and the first mounting post 42 is fixed, the height of the first mounting post 42 is calculated, and the height of the measuring device 43 is precisely positioned. The measuring device 43 is then vertically aligned, and the measuring device 43 is horizontally aligned by adjusting the horizontal disc 41.

[0037] See Figures 3 to 5 The servo motor 22 is fixedly installed inside the equipment box 2. The output end of the servo motor 22 is fixedly connected to the first bevel gear 23. The support cylinder 3 is fixedly connected to the upper surface of the equipment box 2. The fixed bearing 31 is fixedly connected to the inner bottom wall of the support cylinder 3. The transmission shaft 32 is rotatably connected to the inside of the fixed bearing 31. The second bevel gear 33 is fixedly connected to the lower end of the transmission shaft 32. The second bevel gear 33 meshes with the first bevel gear 23. The lifting cylinder 34 is slidably connected to the support cylinder 3. The positioning rod 35 is fixedly connected to the inner top wall of the lifting cylinder 34. The threaded rod 37 is set inside the positioning rod 35. The threaded sleeve 36 is fixedly connected to the lower end of the positioning rod 35. The threaded sleeve 36 is threadedly connected to the threaded rod 37. The lower end of the threaded rod 37 is fixedly connected to the upper end of the transmission shaft 32.

[0038] Meanwhile, during the vertical alignment adjustment of the measuring device 43, the output of the servo motor 22 drives the first bevel gear 23 to rotate, which in turn drives the second bevel gear 33 to rotate. The second bevel gear 33 drives the transmission shaft 32 to rotate inside the fixed bearing 31, which in turn drives the threaded rod 37 to rotate. At this time, since the lifting cylinder 34 positions the positioning rod 35, the height of the positioning rod 35 is adjusted by the threaded sleeve 36 during the rotation of the threaded rod 37, thereby driving the lifting cylinder 34 to rise and fall, and vertically aligning the measuring device 43.

[0039] In addition, in the scenario of measuring settlement inside a tunnel, since satellite signals cannot be received inside the tunnel, an inertial camera is installed inside the tunnel, and this device is placed outside the tunnel in a stable location where satellite signals can be received. A prism target is installed on the upper end of the first mounting column 42. The inertial camera takes pictures of the prism target. If the target position moves during continuous shooting by the inertial camera, but the target position remains unchanged in the information received by the satellite receiving module 52, it can be determined that the tunnel has settled. If the target position does not move during continuous shooting by the inertial camera, but the target position changes in the information received by the satellite receiving module 52, it can also be determined that the tunnel has settled, and the height of the settlement can be further calculated. If the target position does not move during continuous shooting by the inertial camera, and the target position also does not change in the information received by the satellite receiving module 52, it can be determined that the tunnel has not settled.

[0040] The working principle of this utility model is as follows: By using the satellite receiving module 52 to receive satellite signals and obtain the coordinate height information of the equipment, the height of the measuring equipment 43 is adjusted by the adjustment component, so that multiple sets of measuring equipment 43 are kept at the same height, which facilitates the vertical alignment of multiple sets of measuring equipment 43, effectively ensuring the consistency of the measuring equipment 43 in the horizontal and vertical directions, and effectively improving the measurement accuracy.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
