[0001] The utility model belongs to the technical field of tensiometer calibration, and particularly relates to a calibration device for a steel cable tensiometer. Background Art

[0002] After the production of tension measuring instruments and meters is completed, calibration is required to ensure the correct use of the tensiometer. Traditional calibration methods include: 1. Applying a standard load by applying a standard weight to the tensiometer through gravity or a physical device, and then calibrating the tensiometer; 2. Measuring the tensiometer using a sensor, and then comparing the readings of the sensor and the tensiometer.

[0003] However, the above two methods have the following defects during measurement: when applying a standard load, manual operation is often required, which will generate certain measurement errors. At the same time, when the prior art uses a sensor to measure it, a certain force needs to be applied to the tensiometer, which will also generate certain errors, and there is no corresponding comparative analysis to judge the error degree. Content of the Utility Model

A first fixing bracket is installed between the transmission rod and the base plate. A rotating seat is installed on the bottom wall of the base plate, and the transmission rod is rotatably arranged in the rotating seat.

[0011] Further, a driving seat is installed on the bottom wall of the jig body. A transmission rod is threadedly driven in the driving seat. A slide rail is installed on the base plate, and the jig body is slidably arranged on the slide rail.

[0027] As Figure 2 shown in the figure, the utility model provides a calibration device for a steel cable tensiometer. The connection component 503 includes a first connection frame 5031 connected to one end of the tension sensor 502, and a steel wire rope 5032 is connected to the other end of the first connection frame 5031.

[0028] As Figure 1 and Figure 2 shown in the figure, the utility model provides a calibration device for a steel cable tensiometer. The clamping component 4 includes a clamp body 401 slidably arranged on the bottom plate 2. A tensiometer 9 is installed on the clamp body 401, and the tensiometer 9 is connected to the steel wire rope 5032.

[0029] As Figure 1 、 Figure 2 and Figure 4 shown in the figure, the utility model provides a calibration device for a steel cable tensiometer. The driving component 3 includes a first motor 301 installed on the bottom wall of the bottom plate 2. A transmission rod 302 is connected to the output end of the first motor 301. A first fixing frame 501 is installed between the transmission rod 302 and the bottom plate 2. A rotating seat 304 is installed on the bottom wall of the bottom plate 2, and the transmission rod 302 is rotatably arranged in the rotating seat 304.

[0030] As Figure 1 and Figure 4 shown in the figure, the utility model provides a calibration device for a steel cable tensiometer. A driving seat 402 is installed on the bottom wall of the clamp body 401, and the transmission rod 302 is in threaded transmission in the driving seat 402.

[0031] As Figure 1 shown in the figure, the utility model provides a calibration device for a steel cable tensiometer. A slide rail 6 is installed on the bottom plate 2, and the clamp body 401 is slidably arranged on the slide rail 6.

[0032] As Figures 1-3 shown in the figure, the utility model provides a calibration device for a steel cable tensiometer. A grating scale displacement sensor 7 is also installed on the bottom plate 2. The grating scale displacement sensor 7 includes a grating reading head 701 and a grating scale 702. The grating reading head 701 is connected to the inner side of the clamp body 401, the grating scale 702 is fixedly arranged on the bottom plate 2, the grating scale displacement sensor 7 is electrically connected to an industrial computer, and the tension sensor 502 is electrically connected to the industrial computer.

[0033] According to Hooke's Law:

[0034] F = kx;

[0035] where F is the tensile force, k is the elastic coefficient of the wire rope, and x is the deformation displacement of the wire rope. By judging and calculating the deformation displacement of the wire rope, the magnitude of the tensile force can be calculated, and then a comparative analysis can be performed on the tensile force sensor 502.

[0036] As Figure 1 and Figure 2 shown, a calibration device for a wire rope tensiometer provided by the present utility model, a limit head 8 is installed on the bottom plate 2 for restricting the moving position of the clamping assembly 4.

[0037] During specific use,

[0038] firstly, the tensiometer 9 is installed on the clamping assembly 4. By installing the tensiometer 9 on the fixture body 401, after the installation is completed, the driving assembly 3 starts to work. The driving rod 302 is driven to rotate by the first motor 301. Then, the driving rod 302 rotates on the first fixing frame 303 and the rotating seat 304. Further, the driving rod 302 drives the driving seat 402 to move through a threaded transmission method. Since the wire rope 5032 is fixed to the fixture body 401, a loading force is generated, and this loading force acts on the tensiometer 9, and corresponding values are measured by the tensile force sensor 502.

[0039] When the tensile force sensor 502 measures the tensile force value between the wire rope 5032 and the tensiometer 9, the grating reading head 701 moves along with the fixture body 401 on the slide rail 6. Then, the deformation amount of the wire rope 5032 can be measured. Further, the magnitude of the tensile force on the wire rope 5032 is calculated through Hooke's Law. Then, a comparative analysis is performed on the magnitude of the tensile force measured by the tensile force sensor 502 and the magnitude of the tensile force value calculated by the grating displacement sensor 7 to judge whether the force is accurate, so as to accurately calibrate the tensiometer.
