Description

Technical Field

[0001] This utility model relates to the field of intelligent wire rope detection technology, specifically to a cylindrical online wire rope detection equipment. Background Technology

[0002] As a core load-bearing component in lifting, transportation and other operations, the operational safety of wire ropes directly determines the overall reliability of the equipment and the safety of operations. Therefore, the real-time and continuous detection of internal and external damage such as broken wires, wear, and corrosion of wire ropes is particularly important.

[0003] Currently, most online inspection equipment for wire ropes on the market relies on auxiliary translation frames to move and position the inspection components. To ensure inspection stability, these structures are often designed to be bulky and have complex components. On the one hand, they require ample on-site installation space, making them difficult to adapt to confined working environments; on the other hand, the equipment assembly and debugging process is cumbersome, requiring professional personnel, and is inconvenient to move and relocate, making it impossible to quickly respond to multi-station inspection needs. Furthermore, some inspection equipment can only inspect wire ropes of a single specification. When dealing with wire ropes of different diameters and used in different scenarios, core components need to be replaced, resulting in low inspection efficiency and high costs, making it difficult to meet the inspection needs of diverse industrial scenarios. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a cylindrical online wire rope testing equipment.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cylindrical online wire rope inspection device includes a detection probe assembly for detecting damage to the wire rope under inspection using the principle of magnetic leakage; a roller assembly including two sets of rollers symmetrically arranged at both ends of the detection probe assembly for guiding and tensioning the wire rope under inspection; a roller bracket located on the outside of the roller assembly for connecting to external equipment; and a multi-axis adjustment bracket assembly located on the side of the detection probe assembly for multi-angle and multi-directional installation and fixation of the inspection device.

[0006] The beneficial effects of this utility model are: Through the coordinated design of the detection probe assembly, roller assembly, roller bracket, and multi-axis adjustment bracket assembly, the integrated function of online wire rope detection is realized, which solves the problems of large structure and poor adaptability of traditional equipment. Moreover, the structure is lightweight, occupies little space on site, is easy to turn around, and is simple to operate.

[0007] Furthermore, the detection probe assembly includes a first housing and a second housing, which are connected by a hinge. Each housing contains a magnetic flux leakage detection probe, and a magnetic flux leakage detection channel is formed between the two probes. The first and second housings are fitted over the outside of the wire rope, and the wire rope is inspected using the magnetic flux leakage detection probes.

[0008] Furthermore, the magnetic flux leakage detection probe includes a magnetizer, a magnetic sensitive element, and a wear-resistant sleeve. The magnetic sensitive element is fixedly connected to the magnetizer via a probe shoe. The magnetizer is fixedly connected to either a first housing or a second housing. The magnetizer includes an armature and two magnets, with the two magnets respectively disposed at both ends of the armature. Wear-resistant sleeves are provided at both ends of both the first and second housings, and the wear-resistant sleeves are coaxially arranged with the probe shoe. A magnetic field is formed outside the wire rope by the magnetizer, and the wire rope is then detected by the magnetic sensitive element and the probe shoe. The detection result is obtained based on the change in the magnetic field. The structure is simple, the device is small in size and weight, and easy to carry.

[0009] Furthermore, the roller assembly includes two tensioning rollers, which are symmetrically rotatably connected to a wheel frame. The wheel frame is fixedly connected to a wear-resistant sleeve. One of the tensioning rollers is equipped with an encoder. During testing, the tensioning roller abuts against the outer wall of the steel wire rope under test. Specifically, each tensioning roller includes a wheel body and an axle. The wheel body is mounted on the wheel frame via the axle and bearings, and a guide groove is formed on the outer circumferential wall of the wheel body. The symmetrical tensioning rollers ensure stable guidance and tension of the steel wire rope, preventing the rope from swaying during testing and affecting data accuracy. The encoder synchronously records the position information of the steel wire rope, enabling damage localization and improving the practicality of the test data. The wheel body, mounted via the axle and bearings, ensures rotational flexibility. The outer guide groove fits snugly against the steel wire rope, enhancing guiding stability and reducing testing errors caused by steel wire rope deviation. Simultaneously, the wheel body is made of engineering plastic to avoid damage to the steel wire rope.

[0010] Furthermore, the roller bracket is L-shaped and symmetrically fixedly connected to the wheel frame. The upper part of the roller bracket is directly fixedly connected to the external equipment or flexibly connected to the external equipment through an elastic spring. In the case of a flexible connection, the L-shaped bracket, in conjunction with the elastic spring, can adaptively adjust to the position fluctuations of the wire rope, ensuring that the roller assembly and the wire rope are always in reliable contact, compensating for the effects of vibration or sway, and improving the stability of the detection.

[0011] Furthermore, one end of the elastic spring is connected to the roller bracket, and the other end is connected to a set of multi-axis adjustable bracket assemblies. The multi-axis adjustable bracket itself can be installed at multiple angles. After the elastic spring is directly connected to it, the fixed angle adjustment of the bracket can be combined with the dynamic elastic buffering of the spring, adapting to more complex operating conditions.

[0012] Furthermore, the multi-axis adjustment bracket assembly includes a connecting rod. One end of the connecting rod is rotatably connected to a connecting seat or a first connecting joint via a first pin, and the other end is rotatably connected to a rotating component via a first pin. Both ends of the connecting rod are fixedly connected to a first gear. A second gear, meshing with the first gear, is fixedly connected to the rotating component and the first connecting joint / connecting seat. The first connecting joint and the connecting seat are used to fixably connect the detection probe assembly and the elastic tension spring, respectively. The rotating component is rotatably connected to a second connecting joint via a second pin, and a third gear is fixedly connected to the rotating component. A fourth gear, meshing with the third gear, is fixedly connected to the second connecting joint. The second connecting joint is used for fixed connection with external equipment. Through this gear-meshing rotary connection structure, the equipment can be adjusted in multiple axes, significantly improving its adaptability to different installation scenarios and flexibly addressing complex on-site installation needs.

[0013] Furthermore, the first and second pins are perpendicular to each other. This gives the multi-axis adjustment bracket assembly a spatially perpendicular adjustment dimension, enabling a more comprehensive angle adjustment range and further enhancing the flexibility of equipment installation and its adaptability to various scenarios.

[0014] Furthermore, it also includes a terminal data acquisition and control system, which comprises a data acquisition card and a host computer. The input end of the data acquisition card is connected to the magnetic flux leakage detection probe and encoder, and the output end is connected to the host computer via wired or wireless transmission. This enables real-time acquisition of detection data, providing a basis for damage assessment. Attached Figure Description

It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0021] Example 1 like Figures 1 to 4 As shown, this embodiment provides a cylindrical online wire rope inspection equipment, including a detection probe assembly 1 for detecting damage to the wire rope under inspection using the principle of magnetic leakage; a roller assembly 2, including two sets of rollers symmetrically arranged at both ends of the detection probe assembly 1, for guiding and tensioning the wire rope under inspection; a roller bracket 4, located on the outside of the roller assembly 2, for connecting to external equipment; and a multi-axis adjustment bracket assembly 3, located on the side of the detection probe assembly 1, for multi-angle and multi-directional installation and fixation of the inspection equipment. Through the coordinated design of the detection probe assembly 1, roller assembly 2, roller bracket 4, and multi-axis adjustment bracket assembly 3, the integrated function of online wire rope inspection is realized, solving the problems of large structure and poor adaptability of traditional equipment. Furthermore, the structure is lightweight, occupies little space for on-site installation, is convenient to move around, and is simple to operate.

[0022] Specifically: The detection probe assembly 1 includes a first housing 11 and a second housing 12, which are connected by a hinge. Both housings contain a magnetic flux leakage detection probe, and a magnetic flux leakage detection channel is formed between the two probes. The first housing 11 and the second housing 12 are fitted over the outside of the wire rope, and the wire rope is inspected using the magnetic flux leakage detection probes.

[0023] In this embodiment, the magnetic flux leakage detection probe includes a magnetizer, a magnetic sensitive element 14, and a wear-resistant sleeve 15. The magnetic sensitive element 14 is fixedly connected to the magnetizer via a probe shoe 16. The magnetizer is fixedly connected to either a first housing 11 or a second housing 12. The magnetizer includes an armature 13 and two magnets 17, which are respectively disposed at both ends of the armature 13. Wear-resistant sleeves 15 are disposed at both ends of the first housing 11 and the second housing 12, and the wear-resistant sleeves 15 are coaxially arranged with the probe shoe 16. A magnetic field is formed outside the wire rope by the magnetizer, and the wire rope is then detected by the magnetic sensitive element 14 and the probe shoe 16. The detection result is obtained based on the change in the magnetic field. The structure is simple, the device is small in size and weight, and is easy to carry.

[0024] The rollers include two tensioning rollers 21, which are symmetrically rotatably connected to a wheel frame 22. The wheel frame 22 is fixedly connected to a wear-resistant sleeve 15. One of the tensioning rollers 21 is equipped with an encoder 23. During testing, the tensioning roller 21 abuts against the outer wall of the wire rope under test. The symmetrical tensioning rollers 21 ensure stable guidance and tension of the wire rope, preventing the wire rope from swaying during testing and affecting data accuracy. The encoder 23 can simultaneously record the position information of the wire rope, realize damage location, and improve the practicality of the test data.

[0025] In this embodiment, the tensioning roller 21 specifically includes a wheel body and an axle. The wheel body is mounted on a wheel frame 22 via the axle and bearings. A guide groove 24 is formed on the outer peripheral wall of the wheel body. The wheel body is mounted via the axle and bearings to ensure rotational flexibility. The outer peripheral guide groove 24 fits snugly with the wire rope to enhance guiding stability and reduce detection errors caused by wire rope deviation. At the same time, the wheel body is made of engineering plastic material to avoid damage to the wire rope.

[0026] The roller bracket 4 is L-shaped and symmetrically fixedly connected to the wheel frame 22. The upper part of the roller bracket 4 is directly fixedly connected to the external equipment through the mounting holes. The detection equipment is directly and rigidly connected to the external equipment without the need for additional adapters, which reduces the connection gap and the risk of loosening between the bracket and the external equipment. This is especially suitable for installation in compact spaces or vibrating environments.

[0027] The multi-axis adjustable support assembly 3 includes a connecting rod 31. Both ends of the connecting rod 31 are rotatably connected to a first connecting joint 33 and a rotating component 34 via a first pin 32. A first gear 311 is fixedly connected to both ends of the connecting rod 31. A second gear 312, meshing with the first gear 311, is fixedly connected to both the first connecting joint 33 and the rotating component 34. The first connecting joint 33 is fixedly connected to either the first housing 11 or the second housing 12 via a connecting plate 35. The rotating component 34 is rotatably connected to a second connecting joint 37 via a second pin 36. A third gear 341 is fixedly connected to the rotating component 34. A fourth gear 371, meshing with the third gear 341, is fixedly connected to the second connecting joint 37. Through gear meshing and pin fixing and adjustment, the equipment can be adjusted in multiple axes, significantly improving its adaptability to different installation scenarios and flexibly meeting the installation needs of complex sites.

[0028] In this embodiment, the first pin 32 and the second pin 36 are perpendicular to each other. This gives the multi-axis adjustment bracket assembly 3 spatially perpendicular adjustment dimensions, enabling a more comprehensive angle adjustment range and further enhancing the flexibility of equipment installation and its adaptability to different scenarios.

[0029] In this embodiment, a terminal data acquisition and control system (not shown in the figure) is also included. This system comprises a data acquisition card and a host computer. Both the data acquisition card and the host computer can utilize mature technologies, such as laptops or all-in-one computers. Therefore, their specific structure and connection methods can be implemented with reference to existing technologies and will not be elaborated further here. The input end of the data acquisition card is connected to the magnetic flux leakage detection probe and encoder, and the output end is connected to the host computer via wired or wireless transmission. The terminal data acquisition and control system enables real-time acquisition of detection data, providing a basis for damage assessment.

[0030] Example 2 It is basically the same as Example 1, except that: like Figure 5 As shown, the upper part of the roller bracket 5 is flexibly connected to the external equipment via an elastic tension spring 5. The L-shaped bracket, in conjunction with the elastic tension spring, can move autonomously and freely in real time online according to the spring characteristics, adapting to the position fluctuations of the steel wire rope under test. This ensures that the roller assembly 2 and the steel wire rope are always in reliable contact, compensating for the effects of vibration or sway, and improving the stability of the test.

[0031] Specifically, one end of the elastic spring 5 is connected to the roller bracket 4, and the other end is connected to a multi-axis adjustable bracket assembly 3. The elastic spring 5 is fixedly connected to the connecting seat 38 of the multi-axis adjustable bracket assembly 3 (the connecting seat 38 is fixedly connected to the elastic spring 5, and the connecting seat 38 is rotatably connected to the connecting rod 31 through the first pin 32; a second gear 312 that meshes with the first gear 311 on the connecting rod 31 is fixedly connected to the connecting seat 38). The multi-axis adjustable bracket itself can be installed at multiple angles. After the elastic spring is directly connected to it, the fixed angle adjustment of the bracket can be combined with the dynamic elastic buffer of the spring, adapting to more complex operating conditions.
