Embodiment 1
[0019] Such as figure 1 with figure 2 As shown, the device of this embodiment includes two wheels (1), two wheels (2) and a meter counter (3). The cable to be measured first passes through the gap between the two wheels (1) to eliminate The vertical jitter generated when the cable travels, and then the cable passes through the gap between the two wheels (2), eliminating the horizontal jitter generated when the cable travels, and the cable is pulled out to drive the meter counter Count the meters.
[0020] In this embodiment, two wheel rollers (1) are used at the wire inlet end, which can ensure that the vertical direction jitter of the cable can be eliminated regardless of whether the wire is fed from the upper end or the lower end of the wheel roller (1).
[0021] In this embodiment, the length of the Ф8.16mm steel strand is measured. The measured value is 2500m, and the actual measured value is 2500.5m. Comparing the two data, the error of meter counting is 0.02%.
Embodiment 2
[0023] Such as image 3 with Figure 4 As shown, the device of this embodiment includes four wheels (1), four wheels (2) and a meter counter (3). The cable to be measured first passes through the gap between the two wheels (1) to eliminate The cable jitters in the vertical direction, and then the cable passes through the gap between the two wheels (2), eliminating the cable jitter in the horizontal direction. After the cable is pulled out, the meter counter is driven to count the meters. After the meter counter (3) passes through the gap between the two wheels (2) and the two wheel rollers (1), the jitter of the cable is further eliminated and the meter counting is accurate.
[0024] In this embodiment, the length of the steel-cored aluminum stranded wire with Φ9.0mm is measured. The measured value is 4000m, and the actual measured value is 4000.6m. Comparing the two data, it is found that the meter counting error is 0.015%.
Embodiment 3
[0026] Such as Figure 5 with Image 6 As shown, in this embodiment, the cable to be tested first passes through a member (4) fixed on the bracket. The member (4) has a circular hole (5) with the same diameter as the cable in the direction of the cable travel. After the cable passes through the circular hole (5), the jitter is eliminated, and then the cable clings to the upper surface of the meter counter (3), and the friction force drives the meter counter to rotate for meter counting. The cable pull-out end is set at the same position The symmetrical member (4) with round holes (5) at the inlet end can eliminate jitter at the inlet and outlet ends of the cable, and ensure the accuracy of meter counting to the greatest extent.
[0027] In this embodiment, the length of the steel-cored aluminum stranded wire of Φ9.0mm is measured. The measured value is 3000m, and the actual measured value is 3000.7m. The two data are compared, and the meter counting error is 0.023%.
