Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soft cable testing, and particularly relates to a soft cable tensile strength testing device. Background Technique
[0002] The background technique of the soft cable tensile strength testing device mainly stems from the actual needs during the cable installation process. When installing a cable, a certain amount of tensile force often needs to be applied to the cable to pull it to the fixed installation location. However, if the tensile force is blindly applied, it is very likely to break the cable, which not only affects the performance of the cable but may even lead to the scrapping of the cable in severe cases, and is not conducive to the implementation of the energy conservation and consumption reduction goals.
[0003] A soft cable tensile strength testing device can more conveniently and quickly test the tensile strength of the cable, saving time and costs for enterprises. For example, the device may include an upper tension pulley and a lower tension pulley, with sliding nuts and matching slots respectively set, so that the soft cable whose tensile strength is to be tested can be wound around the slots multiple times on the upper fixture and the lower fixture. In addition, a relative adjustment mechanism may also be set on the upper fixture mounting and the lower fixture mounting to ensure the accuracy of the test.
[0004] The clamping device may not be applicable to all types and sizes of soft cables. If the clamping is not stable enough or the clamping force is uneven, it may lead to inaccurate test results or the cable sliding during the test. In view of this, we have proposed a soft cable tensile strength testing device. Content of the Utility Model
