Description

Technical Field

[0001] This invention belongs to the field of wire rope monitoring technology, specifically relating to a wire rope defect monitoring device based on the fusion of electromagnetic and visual information. Background Technology

[0002] Steel wire rope is a flexible rope made of multiple strands of steel wire twisted according to a specific pattern. It has excellent properties such as high strength, wear resistance, and fatigue resistance, and is widely used in industrial fields such as hoisting, transportation, mining, shipbuilding, construction, and aerospace. Its basic structure usually consists of three core parts: steel wire, strands, and core. The steel wire serves as the main load-bearing unit, and its strength is increased through a cold drawing process. The strands are made of multiple steel wires twisted together. The core provides support and lubrication storage functions, and is divided into two types: metal core (such as steel wire rope core) and fiber core (such as polypropylene and sisal).

[0003] When steel wire ropes are used on cable-stayed bridges for a long time, even minor internal or external damage can have a significant impact, thus requiring monitoring. Existing steel wire rope defect monitoring devices based on the fusion of electromagnetic and visual information cannot adapt to steel wire ropes of different diameters, making them unsuitable for different steel wire ropes. Furthermore, they cannot guarantee smooth operation of the defect monitoring devices at different inclination angles, thus reducing their performance. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wire rope defect monitoring device based on the fusion of electromagnetic and visual information.

[0005] The technical solution adopted to solve the above technical problems is: a wire rope defect monitoring device based on the fusion of electromagnetic and visual information, including a main body that is flipped up and down and a monitoring cavity opened therein, with a set of clamping wheels on the main body at both ends of the monitoring cavity, an electromagnetic sensor and multiple visual probes in the monitoring cavity, and a symmetrical multi-angle adaptation mechanism on the main body.

[0006] The multi-angle adaptation mechanism includes a climbing component and a winding component. The climbing component, in cooperation with the winding component, enables the steel wire rope to be wound around at multiple angles. The climbing component is equipped with a squeezing component for pressing against steel wire ropes of different diameters.

[0007] Furthermore, the climbing component includes symmetrically arranged inner and outer rings that are separated vertically, and multiple sliders and a fixed block at the bottom are slidable within the rings. A sleeve rod is rotatably mounted on the slider, and an inner rod with its other end rotatably connected to the slider is provided inside the sleeve rod.

[0008] Furthermore, the ring assembly is provided with a fixing ring for fixation.

[0009] Furthermore, a bracket is provided on the inner rod, and a first motor is provided on one side of the bracket. A roller located on the bracket is fixed at the output end of the first motor.

[0010] Furthermore, the winding assembly includes a gear ring disposed between the ring groups, wherein a second motor is fixed on one of the sliders, and a drive gear meshing with the gear ring is fixed on the output shaft of the second motor.

[0011] Furthermore, a connecting rod is provided between the sliders on the winding assembly.

[0012] Furthermore, the extrusion assembly includes a groove formed inside the sleeve for sliding of the inner rod, a guide post extending through the sleeve on the inner rod, and a spring sleeved on the guide post between the inner rod and the groove.

[0013] The beneficial effects of this invention are as follows:

[0014] (1) By designing climbing components, winding components and squeezing components, the present invention can ensure the stability of the detection process by rotating around the steel wire rope when the steel wire rope defect monitoring device that integrates electromagnetic and visual information is used. At the same time, it is applicable to steel wire ropes of various specifications and diameters, and can maintain the clamping force during the monitoring process, thereby improving the working performance of the detection device.

[0015] (2) The present invention, through the climbing component and the winding component, can facilitate the quick and easy winding and fitting of the wire rope when the monitoring device is in use, so as to ensure that the detection device can be put into use quickly, and at the same time ensure the multi-angle fitting of the wire rope, thus realizing automation;

[0016] (3) The present invention, through the extrusion component, can quickly adapt to the size of steel wire ropes of different diameters by wrapping the steel wire rope, thereby improving the applicability of the monitoring device. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-9 As shown, this embodiment of a wire rope defect monitoring device based on the fusion of electromagnetic and visual information includes a main body 11 that is flipped up and down and a monitoring cavity 12 opened therein. The monitoring cavity 12 is provided with a set of clamping wheels 13 on the main body 11 at both ends. An electromagnetic sensor 14 and a plurality of visual probes 15 are provided in the monitoring cavity 12. A symmetrical multi-angle adaptation mechanism is provided on the main body 11. The multi-angle adaptation mechanism includes a climbing component 2 and a winding component 3. The climbing component 2, with the cooperation of the winding component 3, realizes multi-angle winding of the wire rope. The climbing component 2 is provided with a squeezing component 4 for pressing against wire ropes of different diameter specifications.

[0029] The existing electromagnetic sensor 14 is a large-diameter sensor array based on the principle of strong magnetic leakage, which is a non-contact detection structure. Its core function is to accurately identify internal defects in the wire rope. The vision probe 15 is equipped with a high-resolution industrial camera and polarization suppression technology. Its core function is to accurately capture surface defects in the wire rope and can identify surface damage such as HDPE sheath cracks and surface corrosion.

[0030] The combination of electromagnetic sensor 14 and multiple vision probes 15 enables synchronous data acquisition of internal damage and surface defects in wire ropes, solving the problem that a single sensing mode can only detect one type of defect. It provides complete multimodal feature data for intelligent identification of damage type, location, and degree in subsequent cross-modal fusion algorithms, and is the core foundation for the integrated detection of internal and external defects by the fusion monitoring device.

[0031] like Figures 4-5 As shown, the winding assembly 3 includes a gear ring 33 disposed between the ring groups 21. A second motor 31 is fixed on one of the sliders 23, and a drive gear 32 that meshes with the gear ring 33 is fixed on the output shaft of the second motor 31. A connecting rod 16 is disposed between the sliders 23 on the winding assembly 3.

[0032] In use, the upper and lower main body 11 is opened and fitted onto the steel wire rope used in the cable stay. Then, the electromagnetic sensor 14 and multiple vision probes 15 are activated to detect the inside and outside of the steel wire rope. The second motor 31 is started to drive the drive gear 32 on its output shaft to rotate.

[0033] like Figures 4-7 As shown, the climbing component 2 includes symmetrically arranged inner and outer ring groups 21, separated vertically. Multiple sliders 23 slide within the ring groups 21, and a fixing block 27 is fixed at the bottom. A sleeve rod 24 rotates on each slider 23, and an inner rod 28 with its other end rotatably connected to the slider 23. A fixing ring 22 for fixation is provided on the ring groups 21. A bracket 25 is provided on the inner rod 28, and a first motor 29 is provided on one side of the bracket 25. A roller 26 located on the bracket 25 is fixed to the output end of the first motor 29.

[0034] Since the drive gear 32 meshes with the gear ring 33, it drives the slider 23 to slide along the split ring assembly 21. The ring assembly 21 is split and fixed to the main body 11, facilitating the separation of the main body 11 and the entry of the wire rope into the monitoring chamber 12. Due to the connection of the connecting rod 16, the two sides of the main body 11 begin to move, causing the slider 23 to separate the sleeve rod 24 and the inner rod 28, and slide along the ring assembly 21. Under the pull of the sleeve rod 24 and the inner rod 28, multiple sliders 23 will separate until they are arranged in an array on the outer wall of the wire rope, ensuring stable monitoring by the electromagnetic sensor 14 and the visual probe 15.

[0035] like Figures 8-9 As shown, the extrusion assembly 4 includes a groove 41 formed in the sleeve rod 24 for sliding of the inner rod 28, a guide post 42 that passes through the sleeve rod 24 on the inner rod 28, and a spring 43 sleeved on the guide post 42 between the inner rod 28 and the groove 41.

[0036] Meanwhile, according to the diameter specifications of the wire rope, the inner rod 28 is compressed, which in turn compresses the spring 43 to ensure real-time compression of the wire rope, preventing slippage on wire ropes with inclination angles, while also being applicable to wire ropes of different diameters. Subsequently, multiple first motors 29 are activated to drive the rollers 26 on their output shafts, thereby moving the monitoring device along the wire rope for monitoring.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
