Description

Technical Field

[0001] The present invention relates to the field of chemical fiber rope net detection, in particular to a chemical fiber rope net tensile performance detection device. Background Art

[0002] Chemical fiber ropes and nets are widely used in safety protection (such as safety nets), fishing, transportation, and other fields. Their tensile properties (such as breaking strength, elongation, and yield strength) are key indicators of their quality and safety. The chemical fiber rope and net tensile performance testing device is a specialized device specifically designed to quantify the mechanical behavior of these ropes and nets under tensile loads. Its design must meet multiple requirements, including accuracy, safety, and adaptability.

[0003] However, when testing existing synthetic fiber ropes, a sample is typically cut and then clamped on testing equipment at both ends before stretching to obtain the test results. However, existing testing equipment is generally inconvenient and inflexible in clamping the ends of the synthetic fiber rope, requiring manual winding. Furthermore, after the test, any broken ends of the synthetic fiber rope must be manually unwound, resulting in inefficient and inconvenient operation.

[0004] The publication number CN119958975A is a chemical fiber rope net tensile performance testing device, which discloses "a chemical fiber rope net tensile performance testing device, comprising a base; a fixed seat is fixedly connected to one side of the top surface of the base; a traction seat is slidably connected to the side of the top surface of the base away from the fixed seat; a connecting seat is installed on the side surface of the fixed seat and the traction seat close to each other; a tension sensor is installed between the connecting seat and the traction seat at the traction seat, and the connecting seat at the fixed seat is fixedly connected to the fixed seat, and the upper clamping plate is pressed against the lower clamping plate by the driving component, so that the rope knots at both ends of the sample are respectively clamped by the upper clamping plate and the lower clamping plate at the fixed seat and the traction seat, and then the hydraulic system is started to drive the traction seat away from the fixed seat, thereby stretching the sample, and obtaining specific data through the tension sensor at the traction seat, and then obtaining the tensile performance of the sample. Since the sample has the same weaving structure as the entire chemical fiber rope net, it can better reflect the tensile performance of the entire chemical fiber rope net."

[0005] While the aforementioned technical solution can better reflect the tensile properties of an entire synthetic fiber rope net, it is a flat-lay test, which can cause the rope net to sag, affecting the accuracy of the test results. Furthermore, it is inconvenient to clamp the ends of the rope net and to disassemble it after testing. Therefore, a device for testing the tensile properties of synthetic fiber rope nets is proposed.
