Description

Technical Field

[0001] This utility model relates to the field of fiber rope and net application technology, specifically a rope working condition simulation and testing device. Background Technology

[0002] High-performance synthetic fiber ropes and nets, due to their light weight, high strength, flexibility, and ease of handling, have gradually found widespread application in various fields such as marine engineering, mooring and towing, and industrial lifting. However, high-performance ropes and nets generally face harsh environments in their applications. For example, when used in mines, they may pass through corners, sharp rocks, and metal edges on machinery, and mud, sand, and rock debris may enter the rope strands. Testing indicators for high-performance ropes and nets are no longer limited to traditional indicators such as breaking strength, wire diameter, and elongation. Attention is increasingly being paid to the abrasion resistance, bending resistance, and fatigue resistance of ropes and nets, aiming to simulate the operating conditions of ropes and nets to determine their service life and guide product selection and process improvement. Furthermore, high-performance ropes and nets, especially large-sized products, involve complex manufacturing processes from fiber to net, with numerous intermediate products. Testing the performance of end products is costly and time-consuming, limiting the scope of extensive parameter experiments. Therefore, developing a device capable of simulating rope operating conditions and rapidly testing the performance of ropes and nets is essential. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a rope working condition simulation testing device. By simulating different real-world usage conditions of rope nets, it can quickly test various physical and mechanical properties of rope products under different working conditions, such as bending fatigue resistance, sharp angle resistance, and friction resistance.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wire rope working condition simulation testing device includes a frame, a power source component, a working condition simulation component, a load-bearing component, a testing component, and a wet testing frame. The frame has multiple workstations, each with its own power source component, working condition simulation component, load-bearing component, and testing component. A horizontal and vertical slide rail are located on the front of the frame. Several guide pulleys are mounted on the horizontal slide rail. The bottom of the vertical slide rail is suspended, and the working condition simulation component is movably mounted on it. Testing components are symmetrically arranged on both sides of the working condition simulation component. The load-bearing component is located at the bottom of the frame. A guide plate is mounted on the power source component. During testing, the wire rope to be tested is fixed to the power source component, wound around the working condition simulation component via the guide plate and guide pulleys, and then fixedly connected to the load-bearing component via the guide pulleys. The wet testing frame is detachably mounted at the bottom of the frame and has a test cup for holding liquid. During wet testing, the vertical slide rail is placed inside the test cup, ensuring that the working condition simulation component and the area where the wire rope to be tested is wound are submerged in the liquid.

[0005] The frame is configured as a frame structure, and the horizontal and vertical slide rails are configured as groove structures. The guide pulleys and working condition simulation components can move parallel within the grooves.

[0006] The operating condition simulation component is configured as a component of different shapes and sizes, such as a wedge, a friction component, or a pulley, to simulate the operating conditions.

[0007] The size of the guide pulley and the distance between the two guide pulleys are both adjustable.

[0008] The test components are configured to include a sensor, counter, and proximity switch with relevant parameters.

[0009] The power source component is a reciprocating motor.

[0010] This invention designs a frame capable of providing multi-station testing for rope performance. By adjusting the shape, size, height, and winding angle of the simulated working condition components, it simulates the stress conditions of the rope under actual use. Force is applied to the rope through the power source and load-bearing components, and the strength retention rate or failure cycle count of the rope before and after testing is recorded. This allows for the testing of the rope's physical and mechanical properties, such as bending fatigue resistance, sharp angle resistance, and abrasion resistance. The multi-station design allows for simultaneous testing of multiple ropes, improving testing efficiency, and wet testing can be performed as needed. The principle is simple, operation is convenient, and the various adjustable components are easy to replace. By testing the rope's performance, the product's life cycle can be determined, and the manufacturing process parameters of the rope net can be optimized based on the test results. This provides more precise technical support for guiding customers in selecting rope net products and is suitable for large-scale application. Attached Figure Description
