[0021] Compared with existing technologies, when the wire rope sample is subjected to surface image acquisition through this wire rope tensioning and rotation device, in the initial state, the rotating chuck causes the protruding end of the spring pin to engage in the positioning recess on the end face of the support seat. Then, one end of the wire rope sample is fixed by the chuck at the fixed end of the wire rope clamping, and the other end of the wire rope sample is fixed by the chuck at the sliding end of the wire rope clamping. Then, by rotating the lead screw of the lead screw and nut transmission mechanism, the wire rope clamping rotating assembly at the sliding end of the wire rope clamping can be moved away from the wire rope clamping rotating assembly at the fixed end of the wire rope clamping until the wire rope sample is taut. Surface image acquisition of the wire rope sample can then be performed. During the image acquisition process, after acquiring an image in one direction, the chuck at the fixed end of the wire rope clamping or the chuck at the sliding end of the wire rope clamping is rotated to a set angle and positioned by the spring pin to continue acquiring images until 360° all-round image acquisition of the wire rope sample is completed. On the one hand, the wire rope clamping and rotating mechanism and the wire rope tensioning mechanism can enable rapid tensioning and replacement of wire rope samples. On the other hand, during image acquisition, the multiple spring pins and positioning recesses can accurately position and lock the wire rope sample at each predetermined angle during rotation, ensuring the integrity of image acquisition. Furthermore, the synchronous rotation mechanism allows the chuck at the fixed end of the wire rope clamping and the chuck at the sliding end of the wire rope clamping to rotate synchronously, improving the convenience and accuracy of image acquisition and meeting the testing requirements for efficient surface image acquisition of large-diameter wire ropes.

Abstract
Description
Technical Field
[0001] This utility model relates to a device for steel wire rope inspection, specifically a steel wire rope tensioning and rotation device used in the process of image acquisition and defect analysis and inspection of the surface of steel wire rope, belonging to the field of steel wire rope inspection technology. Background Technology
[0002] Steel wire ropes are essential components or materials in metallurgy, mining, oil and gas drilling, machinery, chemical industry, aerospace, and other fields. Especially in mine hoisting systems, their safety directly impacts personnel safety and production continuity, making regular maintenance and inspection extremely important. Service life assessment and safety monitoring of steel wire ropes require image acquisition and defect analysis of the rope surface. To ensure the completeness and accuracy of image acquisition, a section of the steel wire rope sample must first be tightened and fixed to a steel wire rope fixing device. The image acquisition device is then aligned with this section of the steel wire rope to acquire an image. After acquiring an image from one direction, the steel wire rope is rotated and image acquisition is repeated, and so on, to achieve full circumferential surface coverage imaging of the steel wire rope.
[0003] Existing wire rope fixing devices primarily use clamps, manual clamps, ratchet tensioners, or threaded clamps for securing wire ropes. However, for large-diameter wire ropes with a diameter of Φ20mm or more, the following problems are commonly found:
[0004] 1. Low tensioning efficiency: The clamping process is cumbersome and the loosening is difficult, making it difficult to adapt to the testing process of frequently changing wire ropes;
[0005] 2. Poor rotation control: It cannot achieve segmented rotation and fixed positioning at equal angles, which easily causes angular deviations and affects the accuracy of the acquired images;
[0006] 3. Large structural volume and inconvenient operation: not suitable for integrated use on laboratory benches or in industrial settings;
[0007] 4. Lacks rapid reset and repetitive operation capabilities, resulting in low efficiency under batch testing requirements.
[0008] Furthermore, most of the existing equipment for wire rope testing is designed for wire rope tensioning or cable adjustment during operation. Its structure and function have not been optimized for the needs of static rotation testing of wire ropes, and it has significant limitations in terms of fixing accuracy, ease of operation, angle control, and quick unlocking. Summary of the Invention
[0009] To address the problems existing in the prior art, this utility model provides a wire rope tensioning and rotating device with a compact structure and simple operation. It has functions such as rapid tensioning, controllable rotation, precise positioning, and repeatable assembly and disassembly, which can meet the testing requirements for efficient surface image acquisition of large-diameter wire ropes.
[0010] To achieve the above objectives, the wire rope tensioning and rotating device includes a wire rope clamping and rotating mechanism, a wire rope tensioning mechanism, and a synchronous rotating mechanism mounted on the frame.
[0011] The wire rope clamping and rotating mechanism includes two sets of wire rope clamping and rotating assemblies and support seats arranged in opposite directions. One set serves as the wire rope clamping fixed end, and the other set serves as the wire rope clamping sliding end. The wire rope clamping and rotating assembly includes a chuck, a turntable, an inner positioning bushing, and a locking end cover that are coaxially connected in sequence. The chuck is fixedly connected to the turntable. The edge of the turntable is provided with a roller surface structure. One end of the inner positioning bushing is connected to the turntable through a bearing in a rolling fit. The locking end cover, which is fitted onto the inner positioning bushing, is fixedly connected to the turntable. The other end of the inner positioning bushing is fixedly connected to the support seat. The end face of the locking end cover facing the support seat is also provided with multiple spring pins that extend towards the support seat and abut against the end face of the support seat. The multiple spring pins are symmetrically arranged with respect to the center of the locking end cover. The extended ends of the spring pins are spherical structures. The end face of the support seat is provided with multiple matching positioning recesses corresponding to the positions of the multiple spring pins. The support seat of the wire rope clamping fixed end is fixedly connected to the frame.
[0012] The wire rope tensioning mechanism is located on one side of the wire rope clamping and sliding end, and includes a lead screw and nut transmission mechanism and a guide sliding mechanism; the lead screw and nut transmission mechanism includes a lead screw and a lead nut that are fitted together, and the lead nut is fixedly installed in the inner positioning bushing; the guide sliding mechanism includes a linear guide rail that is set along the front and rear direction and fixedly installed on the frame and a slider that is fitted on the linear guide rail, and the slider is fixedly installed and connected to the support seat of the wire rope clamping and sliding end;
[0013] The synchronous rotation mechanism includes a drive shaft and synchronous rollers. The drive shaft, which is axially arranged along the front-rear direction, is mounted on the frame through a drive bearing seat. Two synchronous rollers are provided, corresponding to the wire rope clamping fixed end and the wire rope clamping sliding end. The synchronous rollers are coaxially mounted on the drive shaft and are radially positioned relative to the drive shaft. The wheel surface of one synchronous roller abuts against the turntable roller surface structure of the wire rope clamping fixed end, and the wheel surface of the other synchronous roller abuts against the turntable roller surface structure of the wire rope clamping sliding end.
[0014] As one embodiment of this utility model, a spline connection structure is provided between the synchronous roller and the transmission shaft.
[0015] In another embodiment of this utility model, the transmission shaft is coaxially spaced in two pieces, and the two transmission shafts are connected by a telescopic coupling.
[0016] As a further improvement of this utility model, the bearing is configured as two pieces, one in front and one behind the inner positioning bushing.
[0017] As a preferred embodiment of this utility model, the central angle between two adjacent spring pins is 60°.
[0018] As a preferred embodiment of this utility model, the chuck is a three-jaw chuck.
[0019] As a preferred embodiment of this utility model, the threaded fit between the lead screw and the lead nut in the lead screw and lead nut transmission mechanism is a trapezoidal thread fit.
[0020] As a further improvement of this utility model, the lead screw of the lead screw and nut transmission mechanism is mounted on the frame through a lead screw bearing seat.
[0021] Compared with existing technologies, when the wire rope sample is subjected to surface image acquisition through this wire rope tensioning and rotation device, in the initial state, the rotating chuck causes the protruding end of the spring pin to engage in the positioning recess on the end face of the support seat. Then, one end of the wire rope sample is fixed by the chuck at the fixed end of the wire rope clamping, and the other end of the wire rope sample is fixed by the chuck at the sliding end of the wire rope clamping. Then, by rotating the lead screw of the lead screw and nut transmission mechanism, the wire rope clamping rotating assembly at the sliding end of the wire rope clamping can be moved away from the wire rope clamping rotating assembly at the fixed end of the wire rope clamping until the wire rope sample is taut. Surface image acquisition of the wire rope sample can then be performed. During the image acquisition process, after acquiring an image in one direction, the chuck at the fixed end of the wire rope clamping or the chuck at the sliding end of the wire rope clamping is rotated to a set angle and positioned by the spring pin to continue acquiring images until 360° all-round image acquisition of the wire rope sample is completed. On the one hand, the wire rope clamping and rotating mechanism and the wire rope tensioning mechanism can enable rapid tensioning and replacement of wire rope samples. On the other hand, during image acquisition, the multiple spring pins and positioning recesses can accurately position and lock the wire rope sample at each predetermined angle during rotation, ensuring the integrity of image acquisition. Furthermore, the synchronous rotation mechanism allows the chuck at the fixed end of the wire rope clamping and the chuck at the sliding end of the wire rope clamping to rotate synchronously, improving the convenience and accuracy of image acquisition and meeting the testing requirements for efficient surface image acquisition of large-diameter wire ropes.

[0028] The present invention will be further described below with reference to the accompanying drawings (the following description refers to the front-to-back direction of the wire rope).
[0029] like Figure 1 As shown, this wire rope tensioning and rotating device includes a wire rope clamping and rotating mechanism, a wire rope tensioning mechanism 2, and a synchronous rotating mechanism mounted on the frame.
[0030] The wire rope clamping and rotating mechanism includes two sets of wire rope clamping and rotating assemblies 1 and a support base 10 arranged in opposition to each other. One set serves as the fixed end for clamping the wire rope, and the other set serves as the sliding end for clamping the wire rope. Figure 2 As shown, the wire rope clamping rotating assembly 1 includes a chuck 4, a turntable 5, an inner positioning sleeve 7, and a locking end cover 8, which are coaxially connected in sequence. The chuck 4 can be a three-jaw chuck or a four-jaw chuck, preferably a three-jaw chuck. The body end of the chuck 4 is fixedly connected to the turntable 5. The edge of the turntable 5 is provided with a roller surface structure coaxially arranged with it. The turntable 5 has a bearing seat structure on its surface. One end of the inner positioning sleeve 7 is connected to the turntable 5 through a bearing 6 installed in the bearing seat structure of the turntable 5 in a rolling fit. The locking end cover 8, which is fitted onto the inner positioning sleeve 7, is fixedly connected to the turntable 5 by mounting bolts. The inner and outer rings of the bearing 6 are positioned by the bearing seat structure of the turntable 5 and the locking end cover 8, respectively. The other end of the inner positioning sleeve 7 is fixedly connected to the support base 10. Figure 3 , Figure 4As shown, multiple spring pins 9 are also installed on the end face of the locking end cover 8 facing the support base 10, extending towards the support base 10 and abutting against the end face of the support base 10. The multiple spring pins 9 are symmetrically arranged with respect to the locking end cover 8. The protruding end of the spring pin 9 has a spherical structure. The central angle between two adjacent spring pins 9 can be 60° (6 spring pins 9 in total) or 90° (4 spring pins 9 in total). The end face of the support base 10 has multiple positioning recesses 15 that cooperate with the spherical structure of the spring pins 9 at the corresponding positions. The support base 10 of the wire rope clamping and fixing end is fixedly connected to the frame.
[0031] The wire rope tensioning mechanism 2 is located on one side of the wire rope clamping and sliding end, such as... Figure 3 As shown, it includes a lead screw and nut transmission mechanism 11 and a guide sliding mechanism; the lead screw and nut transmission mechanism 11 includes a lead screw and a nut that are fitted together, and the nut is fixedly installed in the inner positioning bushing 7. The lead screw can be mounted on the frame through the lead screw bearing seat. Since the trapezoidal thread has a self-locking function, the thread fit between the lead screw and the nut is preferably a trapezoidal thread fit; the guide sliding mechanism includes a linear guide rail 12 that is set along the front-back direction and fixedly installed on the frame and a slider 13 that is fitted on the linear guide rail 12. The slider 13 is fixedly connected to the support seat 10 of the wire rope clamping sliding end through the guide rail base 14.
[0032] The synchronous rotation mechanism is set between the two sets of wire rope clamping rotation components 1, such as... Figure 1 , Figure 5 As shown, the device includes a drive shaft 3 and synchronous rollers 16. The drive shaft 3 is mounted on the frame via a drive bearing seat. Two synchronous rollers 16 are provided, corresponding to the wire rope clamping and fixing end and the wire rope clamping and sliding end. The synchronous rollers 16 are coaxially mounted on the drive shaft 3 and are radially positioned relative to the drive shaft 3. The wheel surface of one synchronous roller 16 abuts against the roller surface structure of the turntable 5 at the wire rope clamping and fixing end, and the wheel surface of the other synchronous roller 16 abuts against the roller surface structure of the turntable 5 at the wire rope clamping and sliding end.
[0033] When the wire rope sample is subjected to surface image acquisition through the wire rope tensioning and rotation device, in the initial state, the rotating chuck 4 causes the protruding end of the spring pin 9 to engage in the positioning recess 15 on the end face of the support base 10. Then, one end of the wire rope sample is fixed by the chuck 4 at the fixed end of the wire rope clamping, and the other end of the wire rope sample is fixed by the chuck 4 at the sliding end of the wire rope clamping. Then, by rotating the lead screw of the lead screw and nut transmission mechanism 11, the wire rope clamping rotation component 1 at the sliding end of the wire rope clamping can be moved away from the fixed end of the wire rope clamping until the wire rope sample is taut. Surface image acquisition of the wire rope sample can then be performed. During the image acquisition process, after acquiring an image in one direction, the chuck 4 at the fixed end of the wire rope clamping or the chuck 4 at the sliding end of the wire rope clamping is rotated to a set angle and positioned by the spring pin 9. Image acquisition can then continue until 360° all-round image acquisition of the wire rope sample is completed. On the one hand, the wire rope clamping and rotating mechanism and the wire rope tensioning mechanism 2 can realize the rapid tensioning and replacement of the wire rope sample. On the other hand, during the image acquisition process, the multiple spring pins 9 and positioning recesses 15 can accurately position and lock the wire rope sample at each predetermined angle during rotation, which can ensure the integrity of image acquisition. Moreover, the synchronous rotation mechanism can make the chuck 4 at the fixed end of the wire rope clamping and the chuck 4 at the sliding end of the wire rope clamping rotate synchronously, which can improve the convenience and accuracy of image acquisition and meet the testing requirements for efficient surface image acquisition of large-diameter wire ropes.
[0034] In order to ensure that the synchronous roller 16 can accurately abut against the roller surface structure of the turntable 5 after the wire rope is taut, a spline connection structure can be set between the synchronous roller 16 and the drive shaft 3, or the drive shaft 3 can be set to two coaxially spaced pieces, and the two drive shafts 3 can be connected by a telescopic coupling 17 that can extend or shorten along the axial direction.
[0035] To achieve more stable rotational engagement and further improve image acquisition accuracy, such as Figure 2 As shown, the outer surface of the inner positioning bushing 7 is provided with a positioning step, and the bearing 6 can be set as two pieces in front and behind the inner positioning bushing 7, and the two bearings 6 are tapered roller bearings arranged in front and behind respectively.
