Description

Technical Field

[0001] The invention relates to the technical field of calibrating an inclinometer, and in particular to a high-efficiency calibration device and method for calibrating an inclinometer. Background Art

[0002] The function of an inclinometer is to measure the tilt angle of the object being measured. Specifically, it is used for long-term monitoring of layered horizontal displacement deformation of dams, foundation walls, slopes, retaining walls and other similar structures, or when installed alone, it is used to measure the tilt change of a building or structure.

[0003] Among them, the structure of the inclinometer 1 is as follows Figure 1 As shown, a contact column head 2 is arranged on it. Since the inclinometer 1 is usually installed in a hidden working environment for operation, it is difficult to perform maintenance and replacement. Therefore, when the user receives a batch of inclinometers from the instrument factory, the user uses a calibration device to calibrate the received batch of inclinometers (because the performance of the inclinometer 1 may change during the transportation and storage of the inclinometer 1 from the instrument factory to the user, therefore, the received inclinometer 1 needs to be calibrated) to determine whether the performance of the inclinometer meets the use requirements.

[0004] The structure of a calibration device is as follows: Figure 2~Figure 3 As shown, it includes a workbench 3, a fixed arm 4 fixed on the top surface of the workbench 3, a rotating arm 6 rotatably installed on 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 display angle meter 8 is fixed on the front end surface of the rotating arm 6.

[0005] The operation steps for workers to calibrate the received inclinometer 1 using the calibration device are as follows:

[0006] S1. The worker takes out an inclinometer 1 to be calibrated, and then uses adhesive tape 9 to stick and fix the inclinometer 1 on the front end surface of the rotating arm 6, and ensures that the inclinometer 1 is in a vertical state, so as to install and fix the first inclinometer 1 to be calibrated. Figure 4~Figure 5 As shown;

[0007] S2. The worker connects the signal line A10 to the contact column head 2 of the inclinometer 1, and connects the other end of the signal line A10 to the access end of the reading instrument 11;

[0008] S3, the worker controls the stepper motor 7 to start, the stepper motor 7 drives the shaft 5 to rotate, and the shaft 5 drives the rotating arm 6 to rotate, such as Figure 6As shown, the rotating arm 6 drives the inclinometer 1 and the digital display angle meter 8 to rotate synchronously. When the digital display angle meter 8 displays 5° (this angle is the first range of the inclinometer 1), the worker controls the stepper motor 7 to turn off, and then the worker records the angle value displayed on the reading instrument 11, which is the current actual angle of the inclinometer 1; then the angle value is subtracted from 5° to obtain the first difference;

[0009] S4, the worker controls the stepper motor 7 to start, and the rotating arm 6 drives the inclinometer 1 and the digital display angle meter 8 to rotate synchronously. When the digital display angle meter 8 displays 10° (this angle is the second range of the inclinometer 1), the worker controls the stepper motor 7 to turn off, and then the worker records the angle value displayed on the reading instrument 11, which is the current actual angle of the inclinometer 1; then the angle value is subtracted by 10° to obtain the second difference;

[0010] S5, the worker repeats the operation of step S4 multiple times to obtain multiple difference values, thereby finally completing the calibration of the first inclinometer 1;

[0011] S6. The worker analyzes and processes the obtained multiple differences to determine whether the performance of the inclinometer 1 meets the requirements;

[0012] S7. The worker repeats the operations of steps S1 to S6 to continuously calibrate multiple inclinometers 1.

[0013] However, although this calibration device can calibrate a batch of inclinometers 1 received, in actual operation, it still reflects the following technical defects:

[0014] I. In step S1, the inclinometer 1 needs to be attached and fixed to the front end surface of the rotating arm 6 with adhesive tape 9, so that the inclinometer 1 to be calibrated can be installed on the rotating arm 6; wherein, multiple adhesive tapes 9 are required to fix the inclinometer 1, which undoubtedly increases the bonding and fixing time of the inclinometer 1, thereby reducing the calibration efficiency of the inclinometer 1. In addition, the number of inclinometers 1 to be calibrated is as many as 50 to 60, and the method of manually fixing them with adhesive tape 9 results in a long time to calibrate all the inclinometers 1, thereby further reducing the calibration efficiency of the inclinometer 1.

[0015] II. In step S2, before calibrating each inclinometer 1, it is necessary to manually connect the inclinometer 1 and the reader 11 with the signal line A10, so that the current actual angle of the inclinometer 1 can be displayed through the reader 11; and 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.

[0016] Therefore, there is an urgent need for a calibration device and method that can greatly shorten the calibration time of an inclinometer and greatly improve the calibration efficiency of an inclinometer. Summary of the invention

[0077] The workbench 3 is also provided with a longitudinally arranged turnover assembly 25 for rotating the inclinometer 1 to be calibrated. The turnover assembly 25 includes an opening 30 provided in the fixed arm 4, a linear electric cylinder 31 penetrating the opening 30 and fixed to the workbench 3, a longitudinally arranged moving plate 33 is fixed on the top surface of the moving part 32 of the linear electric cylinder 31, a plurality of support seats 34 are fixed on the top surface of the moving plate 33 and spaced along the length direction thereof, each support seat 34 is provided with a countersunk groove 35, the small groove of the countersunk groove 35 penetrating downwardly the bottom surface of the moving plate 33; two through holes 36 provided on the moving plate 33 are provided on both sides of each support seat 34. The large groove of the countersunk groove 35 matches the outer contour of the inclinometer 1.

[0078] The calibration device also includes a controller, which is electrically connected to the lifting cylinder 21, the driving cylinder 26, the linear cylinder 31 and the stepper motor 7 via a signal line. Workers can use the controller to control the extension or retraction of the piston rods of the lifting cylinder 21 and the driving cylinder 26, and can also control the start or stop of the linear cylinder 31 and the stepper motor 7, thereby facilitating the workers' operation.

[0079] A high efficiency calibration method for an inclinometer, comprising the following steps:

[0080] S1. The worker takes out a plurality of inclinometers 1 to be calibrated, and then places an inclinometer 1 in each countersunk groove 35 of each support seat 34 of the turnover assembly 25. Since the large groove of the countersunk groove 35 matches the outer contour of the inclinometer 1, the positioning of the plurality of inclinometers 1 is achieved, such as Figure 17-18 As shown;

[0081] S2, the linear electric cylinder 31 of the control turnover assembly 25 is started, the moving part 32 on the linear electric cylinder 31 drives the moving plate 33 to move forward, and the moving plate 33 drives each support seat 34 and the inclinometer 1 to move forward synchronously. When the moving part 32 moves to the set distance, the controller controls the linear electric cylinder 31 to close. At this time, the countersunk groove 35 of the first support seat 34 is just above the jacking block 23. At the same time, the through holes 36 on both sides of the first support seat 34 are respectively above the two square heads 29. At the same time, the inclinometer 1 in the first support seat 34 is just below the vertical cylinder 13.

[0082] S3, installing the inclinometer 1 in the first support seat 34 into the vertical tube 13, the specific operation steps are:

[0083] S31, the worker controls the piston rods of the driving electric cylinders 26 of the two driving assemblies 24 to extend, the piston rods drive the thin rods 28 to move upward, the thin rods 28 drive the square heads 29 to move upward, the square heads 29 pass through the through holes 36 and enter the rectangular grooves 18 of the baffle 17, as shown in FIG. Fig.19 As shown, at this time, the square head 29 cooperates with the rectangular groove 18;

[0084] S32, the driving motor 27 of the control driving assembly 24 is started, the driving motor 27 drives the thin rod 28 to rotate, the thin rod 28 drives the square head 29 to rotate, the square head 29 drives the baffle 17 to rotate synchronously, the baffle 17 moves away from the vertical tube 13, and at the same time, the baffle 17 causes the torsion spring 19 to twist and deform. When the baffle 17 rotates 180°, the controller controls the driving motor 27 to turn off. At this time, the baffle 17 no longer blocks the bottom port of the vertical tube 13. Fig. 20 As shown;

[0085] S33, control the piston rod of the lifting electric cylinder 21 to extend upward, the piston rod drives the rod 22 to move upward, the rod 22 drives the lifting block 23 to move upward synchronously, the lifting block 23 enters the countersunk groove 35 of the first support seat 34, and then the lifting block 23 lifts the inclinometer 1 in the first support seat 34 upward. When the piston rod of the lifting electric cylinder 21 is fully extended, the inclinometer 1 just enters the vertical tube 13, as shown in FIG. Fig.21 As shown, the contact column head 2 of the inclinometer 1 just contacts the conductive column 14;

[0086] S34, control the piston rods of the driving electric cylinders 26 of the two driving components 24 to retract downward, the piston rod drives the thin rod 28 to move downward, and the thin rod 28 drives the square head 29 to move downward. When the square head 29 escapes from the rectangular groove 18 of the baffle 17, the baffle 17 rotates in the opposite direction around the axis of the fixed rod 16 under the restoring force of the torsion spring 19, and the baffle 17 blocks the bottom end of the vertical tube 13 again. Fig. 22 As shown, the inclinometer 1 located in the vertical tube 13 is supported;

[0087] S35, control the piston rod of the lifting electric cylinder 21 to retract downward, and the piston rod drives the rod 22 and the lifting block 23 to move downward. When the lifting block 23 is reset, the inclinometer 1 in the first support seat 34 is installed in the vertical tube 13. Figure 23~Figure 24 As shown;

[0088] Among them, it can be seen from step S3 that the calibration device can automatically install the inclinometer 1 to be calibrated in the support seat 34 into the vertical tube 13 only through the linkage cooperation of the driving component 24, the lifting cylinder 21, the baffle 17 and the torsion spring 19. It can be seen that compared with the calibration device of the present invention, the inclinometer 1 to be calibrated in the support seat 34 is automatically installed in the vertical tube 13. Figure 2~Figure 6 The calibration device shown does not require workers to use multiple adhesive tapes 9 to fix the inclinometer 1, thereby greatly shortening the installation time of the inclinometer 1 and further greatly improving the calibration efficiency of the inclinometer.

[0089] In addition, when the inclinometer 1 is installed in the vertical tube 13, the contact column head 2 of the inclinometer 1 automatically contacts the conductive column 14, thereby automatically connecting the inclinometer 1, the signal line B15 and the reading instrument 11 in series. Therefore, it is not necessary to connect the reading instrument 11 with the contact column head 2 of the inclinometer 1 with the signal line A10 every time before calibrating an inclinometer 1, thereby greatly shortening the installation time of the inclinometer 1 and further improving the calibration efficiency of the inclinometer.

[0090] S4, the worker controls the stepper motor 7 to start, the stepper motor 7 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the rotating arm 6 to rotate, and the rotating arm 6 drives the inclinometer 1 and the digital display angle meter 8 to rotate synchronously, such as Fig.25 As shown, when the digital display angle meter 8 displays 5°, the worker controls the stepper motor 7 to turn off, and then the worker records the angle value displayed on the reading instrument 11, which is the current actual angle of the inclinometer 1; and then subtracts 5° from the angle value to obtain the first difference;

[0091] S5, the worker controls the stepper motor 7 to start, and the rotating arm 6 drives the inclinometer 1 and the digital display angle meter 8 to rotate synchronously. When the digital display angle meter 8 displays 10°, the worker controls the stepper motor 7 to turn off, and then the worker records the angle value displayed on the reading instrument 11, which is the current actual angle of the inclinometer 1; then the angle value is subtracted by 10° to obtain the second difference;

[0092] S6, the worker repeats the operation of step S5 for multiple times to obtain multiple difference values, thereby finally completing the calibration of the first inclinometer 1;

[0093] S7, the worker analyzes and processes the obtained multiple differences to determine whether the performance of the inclinometer 1 meets the requirements; the worker repeats the operations of steps S31 to S32 once to remove the inclinometer 1 in the vertical tube 13;

[0094] S8. The worker repeats the operations of steps S1 to S7 to continuously calibrate multiple inclinometers 1.

[0095] Among them, it can be known from steps S1 to S8 that the calibration device can automatically install the inclinometers 1 on the turnover assembly 25 into the vertical tube 13 one by one through the linkage cooperation of the turnover assembly 25, the lifting cylinder 21, and the driving assembly 24, so that the inclinometers 1 can quickly enter the calibration station, thereby completing the calibration of 50 to 60 inclinometers 1 in a short time, thereby greatly improving the calibration efficiency of the inclinometers.
