Problems solved by technology

[0005] Although the device can complete a certain test, it is greatly affected by external factors. As the test continues, the tensile machine will inevitably be fatigued and overheated due to long-term work, so that the set tensile value cannot be kept constant continuously. Multiple adjustments are not only time-consuming and laborious, but also result in inaccurate test results, which cannot meet the long-term testing of large batches of products; at the same time, the device has no fault-tolerant mechanism. Once the machine fails due to long-term work, the test device will be in a paralyzed state. , unable to achieve online adjustment, unable to achieve continuous and effective testing, resulting in low work efficiency

Abstract

The invention relates to a cable tension testing device, which comprises: a power source module (1), which provides output power; an oil cylinder (74), to which cables are connected; The output end of the source module (1) is connected, and the output end is connected to the oil cylinder (74), which receives the output power and generates a constant tension; the oil cylinder (74) moves under the action of the constant tension, and the control cable is tested according to the constant tension . Compared with the prior art, the invention improves the working efficiency and working precision of the cable fatigue testing device.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable tension testing device for cable fatigue testing. Background technique [0002] Large-scale cables, especially offshore engineering cables or umbilical cables, must undergo sufficient mechanical performance tests, such as fatigue tests, before they are officially put into use. In actual engineering, the umbilical cable transmits energy and power from the mother ship, such as a workboat or an offshore platform, to the underwater working device, and the underwater working device is often affected by various factors such as gravity and waves, which will generate a certain amount of tension and force on the mother ship. Therefore, in order to keep the overall system stable, the mother ship will have a certain amount of cable storage to maintain a certain tension state and deal with complex and changeable underwater situations. [0003] Laboratory tests cannot prepare a large ...
