Problems solved by technology

[0004] However, when performing tension measurement with the tension measuring instrument in the prior art, it is usually necessary to perform bending stiffness calibration and equipment calibration for each cable to be tested. Not only the measurement process is cumbersome and inefficient, but also the deviation of calibration and correction will be Lead to large deviations in measurement results and low accuracy

Embodiment Construction

[0040] The technical solutions in the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the present disclosure.

[0041] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

[0042] Please refer to figure 1 , is a schematic diagram of a tension measurement principle provided by the publication. The cable to be tested is in the normal tension state A, B, C three points and one line, point C is in the middle of A and B, the distance between points A and B to point C is l, when point C is in the direction of the cable to be tested When the pressure P is applied, the cable to be tested will produce a certain positional deviation (ie deflection δ) in the direction of the line connecting the vertical points A and B. According to the actual deformatio...

Abstract

The invention provides a tension measuring method, which relates to the technical field of measurement. The method is applied to a tension measuring instrument. The tension measuring instrument comprises a support, a transmission assembly, a pressure sensor, a guide wheel and two identical adjusting wheels. The transmission assembly is fixedly arranged on the support and is in transmission connection with the two adjusting wheels. The pressure sensor is fixedly connected with the support and the guide wheel. A preset vertical distance is formed between the axis of the guide wheel and the axesof the adjusting wheels. The method comprises the following steps: 1, a to-be-tested cable is introduced between the axis of the guide wheel and the axes of the two adjusting wheels, the two adjustingwheels are controlled to move through the transmission assembly; when the horizontal distances between the axes of the two adjusting wheels and the axis of the guide wheel are the same and are multiple preset horizontal distances, pressure values corresponding to the preset horizontal distances are measured through the pressure sensor; and the tension of the to-be-tested cable is determined basedon the preset vertical distance, the multiple preset horizontal distances and each pressure value. The tension measuring efficiency and the accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of measurement, and in particular, to a tension measurement method. Background technique [0002] The tension measuring instrument is a commonly used measuring instrument in the field of measurement technology. The tension measuring instrument can measure the tension of ropes, silk threads, cables, etc., so as to carry out subsequent safe production operations according to the measured tension. [0003] In the prior art, the tension measuring instrument includes a moving guide wheel arranged on a support frame and two static guide wheels arranged symmetrically with respect to the moving guide wheel, and the moving guide wheel is connected with a pressure sensor and a manual dial. When measuring with the tension measuring instrument, the moving guide wheel and the two static guide wheels are respectively stuck on both sides of the rope, and the manual dial is moved to drive the moving guide wheel to ...
