Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of inclinometer calibration, and particularly to an efficient calibration device and method used for calibrating an inclinometer.
Background Art
[0002] An inclinometer is to measure the inclination angle of a measured object. Specifically, it is used to long-term monitor the horizontal displacement deformation between layers of similar buildings such as dams, foundation walls, slopes of hills, barriers, etc., or to measure the inclination change of a building or structure when installed alone.
[0003] As shown in FIG. 1, the structure of the inclinometer 1 is provided with a contact member 2. Since the inclinometer 1 is usually operated in a hidden working environment and it is difficult to inspect and replace, after the user receives a batch of inclinometers sent from the instrument factory, the batch of inclinometers need to be calibrated using a calibration device (during the transportation, storage, etc. from the instrument factory of the inclinometer 1 to the user, the performance of the inclinometer 1 may change, so it is necessary to calibrate the received inclinometer 1), and it is necessary to determine whether the performance of the inclinometer meets the usage requirements.
[0004] As shown in FIGS. 2 to 3, the structure of a certain calibration device includes a workbench 3, a fixed arm 4 fixed on the top surface of the workbench 3, a rotary arm 6 rotatably attached to the upper end of the fixed arm 4 via a rotating shaft 5, and a stepping motor 7 fixed on the rear end surface of the fixed arm 4. The output shaft of the stepping motor 7 is connected to the rotating shaft 5, and a digital angle meter 8 is fixed on the front end surface of the rotary arm 6.
[0005] The operation procedure for an operator to calibrate the received inclinometer 1 using this calibration includes the following. After the operator removes the inclinometer 1 to be calibrated, they attach and secure the inclinometer 1 to the front end surface of the rotating arm 6 using adhesive tape 9, and as shown in Figures 4 and 5, the inclinometer 1 is positioned vertically, thereby achieving the mounting and securing of the first inclinometer 1 to be calibrated (S1). The operator connects the signal line A10 to the contact member 2 of the inclinometer 1, and connects the other end of the signal line A10 to the access terminal of the reading device 11, S2. The operator starts the stepping motor 7, which rotates the rotating shaft 5, which rotates the rotating arm 6, and as shown in Figure 6, the rotating arm 6 rotates the inclinometer 1 and the digital angle meter 8 in synchronous motion. When the digital angle meter 8 displays 5° (this angle is the first range of the inclinometer 1), the operator closes the stepping motor 7 and records the angle value displayed on the reading device 11. This angle value is the current actual angle of the inclinometer 1. Then, 5° is subtracted from the angle value to obtain the first difference in S3. The operator starts the stepping motor 7, causing the rotating arm 6 to rotate the inclinometer 1 and the digital angle meter 8 synchronously. When the digital angle meter 8 displays 10° (this angle is the second range of the inclinometer 1), the operator closes the stepping motor 7 and records the angle value displayed on the reading device 11. This angle value is the current actual angle of the inclinometer 1. Then, 10° is subtracted from this angle value to obtain the second difference (S4). The operator repeats the operation of S4 multiple times, obtaining multiple differences, and finally completes the calibration of the first inclinometer 1 in S5. The operator analyzes and processes the multiple differences obtained and determines whether the performance of inclinometer 1 meets the requirements in S6. By repeating the operations in steps S1 to S6 in this manner, the operator can continuously calibrate multiple inclinometers 1 (S7).
[0006] However, while such a calibration device can calibrate a batch of inclinometers 1 received, its actual operation has the following technical deficiencies: 1. In step S1, the inclinometer 1 cannot be attached to the rotating arm 6 unless it is secured using adhesive tape 9 to the front end surface of the rotating arm 6. In this process, multiple pieces of adhesive tape 9 are required to secure the inclinometer 1, which undoubtedly increases the adhesive fixing time of the inclinometer 1 and further reduces the calibration efficiency of the inclinometer 1. Furthermore, since there are 50 to 60 inclinometers 1 to be calibrated, manually securing them with adhesive tape 9 takes a long time to calibrate all of them, further reducing the calibration efficiency of the inclinometer 1. 2. In step S2, before calibrating the inclinometer 1, it is necessary to manually connect the inclinometer 1 to the reading device 11 via the signal line A10, thereby allowing the current actual angle of the inclinometer 1 to be displayed through the reading device 11. However, connecting the signal line A10 each time will undoubtedly increase the calibration time of the inclinometer 1 and further reduce the calibration efficiency of the inclinometer 1.
[0007] Therefore, a calibration device and method are needed that minimizes the calibration time of the inclinometer and maximizes the calibration efficiency of the inclinometer. [Overview of the project] [Means for solving the problem]

A movable plate is fixed vertically to the top surface of the operating part of the linear electric cylinder, and support bases are fixed at intervals along the longitudinal direction of the movable plate on the top surface of the movable plate. Each support base has a counterbore, and a small groove in the counterbore penetrates downward through the bottom surface of the movable plate. Two through holes are provided on both sides of each support base, which are opened in the movable plate.
[0014] The large groove in the aforementioned counterbore is aligned with the outer casing of the inclinometer.
[0015] The calibration device further includes a controller, which is electrically connected via signal lines to the push-up electric cylinder, the drive electric cylinder, the direct-acting electric cylinder, and the stepping motor.
[0016] An efficient calibration method used for calibrating an inclinometer, comprising the following steps: The operator takes out multiple inclinometers to be calibrated, places one inclinometer in the counterbore of each support base of the rotating assembly, and aligns the large groove of the counterbore with the outer casing of the inclinometer to achieve positioning of the multiple inclinometers (S1). The linear electric cylinder of the rotary assembly is activated, and the actuation part on the linear electric cylinder moves the moving plate forward, the moving plate moves each support base and inclinometer forward in sync, and after the actuation part has moved to a predetermined distance, the controller controls the linear electric cylinder to close, at which time the counterbore of the first support base is directly above the push-up block, and at the same time the through holes located on both sides of the first support base are directly above the two square heads, and at the same time the inclinometer in the first support base is directly below S2, which is directly below the vertical cylinder, The following operating procedure is included, S3, which involves installing the inclinometer in the first support base into the vertical cylinder, S31, the operator controls the piston rods of the drive electric cylinders of the two drive assemblies to extend, the piston rods move the thin rod upward, the thin rod moves the square head upward, the square head extends through the through hole into the rectangular groove of the retaining plate, at which point the square head engages with the rectangular groove. In S32, the drive motor of the drive assembly is started and controlled to rotate the thin rod, which rotates the square head, which synchronously rotates the retaining plate. As the retaining plate moves away from the vertical cylinder, the retaining plate simultaneously deforms the torsional spring.

The operator starts the stepping motor, which rotates the rotating shaft, which rotates the rotating arm, which rotates the inclinometer and digital angle meter in synchronous rotation, and when the digital angle meter displays 5°, the operator closes the stepping motor and records the angle value displayed on the reading device, this angle value is the current actual angle of the inclinometer, and then subtracts 5° from the angle value to obtain the first difference S4, The operator starts the stepping motor, and the rotating arm rotates the inclinometer and digital angle meter in sync. When the digital angle meter displays 10°, the operator closes the stepping motor and records the angle value displayed on the reading device. This angle value is the current actual angle of the inclinometer. Then, 10° is subtracted from this angle value to obtain the second difference (S5). The operator repeats operation S5 multiple times, obtaining multiple differences, and finally completes the calibration of the first inclinometer in S6. The worker analyzes and processes the multiple differences obtained, determines whether the performance of the inclinometer meets the requirements, and repeats operations S31-S32 once to remove the inclinometer from the vertical cylinder in S7.

The drive assembly 24 has a drive electric cylinder 26 fixed to the arch frame 20, the piston rod of the drive electric cylinder 26 extends upward through the arch frame 20 and a drive motor 27 fixed to the extended end, a thin rod 28 connected to the output end of the drive motor 27, and a rectangular head 29 extending into the workbench 3 connected to the top end of the thin rod 28, the rectangular head 29 located directly below the rectangular groove 18 of the stopper plate 17.
[0022] The workbench 3 is provided with a vertically oriented rotating assembly 25 for rotating the inclinometer 1 to be calibrated. The rotating assembly 25 includes an opening 30 made in the fixed arm 4 and a linear-acting electric cylinder 31 that passes through the opening 30 and is fixed to the workbench 3. A movable plate 33 is fixed vertically to the top surface of the operating part of the linear-acting electric cylinder 31.

[0023] The calibration device further includes a controller, which is electrically connected via signal lines to the thrust-up electric cylinder 21, the drive electric cylinder 26, the linear electric cylinder 31, and the stepping motor 7. The operator can control the extension and retraction of the piston rods of the thrust-up electric cylinder 21 and the drive electric cylinder 26 via the controller, and can also control the starting or closing of the linear electric cylinder 31 and the stepping motor 7, thereby facilitating operator operation.
[0024] An efficient calibration method used for calibrating an inclinometer, comprising the following steps: As shown in Figures 17 and 18, the operator takes out multiple inclinometers 1 to be calibrated, places one inclinometer 1 in the counterbore 35 of each support base 34 of the rotating assembly 25, and aligns the large groove of the counterbore 35 with the outer casing of the inclinometer 1, thereby achieving positioning of multiple inclinometers 1 in S1. The linear electric cylinder 31 of the rotary assembly 25 is activated, and the actuation unit 32 on the linear electric cylinder 31 moves the moving plate 33 forward, and the moving plate 33 moves each support base 34 and the inclinometer 1 forward in synchronous motion, and after the actuation unit 32 has moved to a predetermined distance, the controller controls the linear electric cylinder 31 to close, at which time the counterbore 35 of the first support base 34 is directly above the push-up block 23, and at the same time the through holes 36 located on both sides of the first support base 34 are directly above the two square heads 29, and at the same time the inclinometer 1 in the first support base 34 is directly below S2, which is directly below the vertical cylinder 13, The following operating procedure is included, S3, which involves installing the inclinometer 1 in the first support base 34 into the vertical cylinder 13, In S31, the operator controls the piston rods of the drive electric cylinders 26 of the two drive assemblies 24 to extend, causing the thin rod 28 to move upward, which in turn moves the square head 29 upward, causing the square head 29 to pass through the through hole 36 and extend into the rectangular groove 18 of the retaining plate 17, at which point the square head 29 engages with the rectangular groove 18, as shown in Figure 19. In S32, the drive motor 27 of the drive assembly 24 is started and controlled to rotate the thin rod 28, which in turn rotates the square head 29, which in turn rotates the stopper plate 17 synchronously. As the stopper plate 17 moves away from the vertical cylinder 13, the stopper plate 17 simultaneously deforms the torsion spring 19, and after the stopper plate has rotated 180°, the controller 27 controls the drive motor to close, so that, as shown in Figure 20, the stopper plate 27 does not obstruct the bottom port of the vertical cylinder 13. In S33, the piston rod of the push-up electric cylinder 21 is controlled to extend upward, causing the piston rod to move the rod member 22 upward, which simultaneously moves the push-up block 23 upward, so that the push-up block 23 enters the counterbore 35 of the first support base 34, the push-up block 23 pushes the inclinometer 1 inside the first support base 34 upward, and after the piston rod of the push-up electric cylinder 21 has fully extended, the inclinometer 1 enters the vertical cylinder 13, as shown in Figure 21, and the contact member 2 of the inclinometer 1 is in contact with the conductive column 14. S34, the piston rod of the drive electric cylinder 26 of the two drive assemblies 24 is controlled to be pulled back downward, the piston rod moves the thin rod 28 downward, the thin rod 28 moves the square head 29 downward, and after the square head 29 has come out of the rectangular groove 18 of the retaining plate 17, the retaining plate 17 rotates in the reverse direction around the axis of the fixed rod 16 under the restoring force of the torsion spring 19, and as shown in Figure 22, the retaining plate 17 again supports the inclinometer 1 located inside the vertical cylinder 13 while shielding the bottom port of the vertical cylinder 13. In S35, the piston rod of the push-up electric cylinder 21 is controlled to pull back downward, causing the piston rod to move the rod member 22 and the push-up block 23 downward. After the push-up block 23 is reset, the inclinometer 1 in the first support base 34 is mounted inside the vertical cylinder 13, as shown in Figures 23-24. As can be seen from step S3, the present invention allows the inclinometer 1 to be calibrated in the support base 34 to be automatically mounted in the vertical cylinder 13 by the interlocking fitting of the drive assembly 24, the push-up electric cylinder 21, the stopper plate 17, and the torsion spring 19. Therefore, compared to the calibration devices shown in Figures 2 to 6, this calibration device eliminates the need for the operator to fix the inclinometer 1 with multiple adhesive tapes 9, significantly reducing the mounting time of the inclinometer 1 and further significantly improving the calibration efficiency for the inclinometer. Furthermore, when the inclinometer 1 is installed inside the vertical cylinder 13, the contact member 2 of the inclinometer 1 automatically contacts the conductive column 14, and the inclinometer 1, signal line B15, and reading device 11 are automatically connected in series. Therefore, it is no longer necessary to connect the reading device 11 and the contact member 2 of the inclinometer 1 using signal line A10 before calibrating a single inclinometer 1, significantly reducing the installation time of the inclinometer 1 and further improving the calibration efficiency for the inclinometer. The operator starts the stepping motor 7, which rotates the rotating shaft 5, which rotates the rotating arm 6, which rotates the inclinometer 1 and the digital angle meter 8 in synchronous rotation, and as shown in Figure 25, when the digital angle meter 8 displays 5°, the operator closes the stepping motor 7 and records the angle value displayed on the reading device 11. This angle value is the current actual angle of the inclinometer 1, and then, by subtracting 5° from the angle value, the first difference is obtained in S4. The operator starts the stepping motor 7, causing the rotating arm 6 to rotate the inclinometer 1 and the digital angle meter 8 synchronously. When the digital angle meter 8 displays 10°, the operator closes the stepping motor 7 and records the angle value displayed on the reading device 11. This angle value is the current actual angle of the inclinometer 1. Then, 10° is subtracted from this angle value to obtain the second difference (S5). The operator repeats operation S5 multiple times, obtaining multiple differences, and finally completes the calibration of the first inclinometer 1 in S6. The worker analyzes and processes the multiple differences obtained to determine whether the performance of the inclinometer 1 meets the requirements, and the worker repeats operations S31-S32 once to remove the inclinometer 1 from the vertical cylinder 13 in S7. S8 allows the operator to continuously calibrate multiple inclinometers 1 by repeating operations S1 to S7.
[0025] As can be seen from steps S1 to S8, this calibration device, through the interlocking fitting of the rotary assembly 25, the push-up electric cylinder 21, and the drive assembly 24, automatically mounts the inclinometers 1 on the rotary assembly 25 one after another into the vertical cylinder 13, and further allows the inclinometers 1 to be quickly moved into the calibration location, enabling the calibration of 50 to 60 inclinometers 1 in a short time and significantly improving the calibration efficiency of the inclinometers.
